Description

Technical Field

[0001] This invention relates to a construction machinery capable of being equipped with an information acquisition device for acquiring information about the surroundings of the construction machinery. Background Technology

[0002] Patent documents 1 and 2 disclose an engineering machine equipped with a camera for capturing images of the surroundings. The camera described in patent documents 1 and 2 is mounted on the cab of the upper rotating body of the engineering machine via a pan-tilt unit or camera housing, and captures images in front of the cab.

[0003] However, the camera and the component supporting it protrude significantly upwards from the cab, potentially exceeding the maximum transport height of the construction machinery. This problem is particularly problematic when transporting the machinery to and from the work site, often by loading it onto low-floor trailers or other freight vehicles. While removing the camera and component from the machinery during transport can solve this issue, repeatedly disassembling and reassembling them for each trip reduces efficiency.

[0004] Existing technical documents Patent documents Patent Document 1: Japanese Patent Publication No. JP9-218713 Patent Document 2: Japanese Patent Publication No. 2008-111269. Summary of the Invention

[0005] The purpose of this invention is to provide a support device for engineering machinery and information acquisition equipment. The engineering machinery can be equipped with information acquisition equipment such as cameras, and the transportation height of the engineering machinery can be reduced without removing the information acquisition equipment when transporting the engineering machinery.

[0006] The present invention provides an engineering machinery, comprising: an engineering machinery body; a retaining part connected to the engineering machinery body; and a supporting member held in the retaining part and supporting at least one information acquisition device for acquiring information about the surroundings of the engineering machinery.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Figure 1 and Figure 2A The first embodiment of the present invention relates to an engineering machinery 10. The engineering machinery 10 includes a lower traveling body 20, an upper rotating body 30, a working mechanism 40, and a support device 50, wherein the lower traveling body 20 and the upper rotating body 30 constitute the main body of the engineering machinery. Figure 1The engineering machinery 10 in the example is construction machinery, specifically a backhoe excavator.

[0033] The lower walking body 20 includes a walking device that moves autonomously in a forward or backward direction. Figure 1 The walking device in the example is a pair of tracks 21 arranged on both sides in the width direction. Alternatively, the walking device may also include multiple tires. The lower walking body 20 corresponds to the undercarriage of construction machinery.

[0034] The upper slewing body 30 is connected to the upper part of the lower traveling body 20 via a slewing bearing (not shown in the figure), and can rotate around a vertical axis of rotation on the upper side of the lower traveling body 20. The upper slewing body 30 includes a cab 31 serving as an operator's cab, allowing an operator to enter the cab 31 and operate the construction machinery 10. The upper slewing body 30 is equipped with multiple components, including the working mechanism 40, the support device 50, a drive source such as an engine (not shown in the figure), multiple actuators, hydraulic circuits (not shown in the figure) for actuating the multiple actuators, and other components.

[0035] The cab 31 forms the front portion of the upper rotating body 30 and the left-hand portion in the width direction of the upper rotating body. The top of the cab 31 is the highest point of the upper rotating body 30, i.e., the uppermost part. An operator's seat 33 is arranged forward within the cab 31, wherein the width direction of the upper rotating body, i.e., the width direction of the cab 31, corresponds to the left-right direction as viewed from the operator seat 33. The upper rotating body 30 has a front-back direction orthogonal to the width direction of the upper rotating body, which corresponds to the front-back direction as viewed from the operator seat 33.

[0036] The cab 31 includes multiple walls that enclose an operating space for receiving the operator. These walls include a top wall 34, a front wall 35, a left side wall 37, a right side wall (not shown), and a rear wall 38, each containing a glass portion. The cab 31 also includes a front surface protector 36 that covers the front surface of the glass portion of the front wall 35 on its front side; and a top surface protector 39 that covers the top surface of the glass portion of the top wall 34 on its upper side. The front wall 35 and the rear wall 38 are erected separately in the longitudinal direction of the upper rotating body, separated by the operating space, with the top wall 34 connected to the upper ends of both the front wall 35 and the rear wall 38. The top wall 34 and the top surface protector 39 disposed on its upper side are components located at the highest point of the main body of the construction machinery. The front surface protector 36 and the top surface protector 39 are grid-like metal components. The cab 31 may also omit some of the multiple walls, such as the top wall 34.

[0037] The control area includes a control seat 33 and multiple operating components 32. Multiple operations required to operate the construction machinery 10 are applied to the multiple operating components 32, such as operations to move the working mechanism 40 and operations to move and stop the lower walking body 20. More specifically, the multiple operating components 32 are located in front of the control seat 33 and include: a control lever and a travel lever for receiving rotational operations performed by the operator seated in the control seat 33; and an operating pedal for receiving foot pedal operations performed by the operator. The interface for operating the construction machinery 10 is not limited to components disposed within the cab 31. The interface may also include components disposed in… Figure 4 The remote operation device 101 shown in the figure has a plurality of remote operation components 102. For example, a working mechanism such as a robot may also be configured in the operating space, the working mechanism being configured to receive a command signal corresponding to an operation applied to the remote operation component 102, and to operate the plurality of operation components 32 in accordance with the command signal.

[0038] The working mechanism 40 includes a boom 41, a stick 42, a distal attachment 43, and a plurality of actuators not shown in the figure. The boom 41 has a base end and a distal end opposite to the base end, the base end being connected to the middle portion of the front of the upper slewing body 30 in the width direction, allowing it to rock vertically. The stick 42 has a base end and a distal end opposite to the base end, the base end being connected to the distal end of the boom 41 in the vertical direction. The cab 31 is positioned to the left of and adjacent to the boom 41 in the width direction of the upper slewing body.

[0039] The distal accessory 43 is mounted on the distal end of the boom 42 in a rocking and detachable manner. Figure 1 The distal attachment 43 in the example is a bucket. However, the distal attachment 43 can also be a component other than a bucket that meets the operational purpose. Through the respective rocking of the boom 41, the stick 42, and the distal attachment 43, the distal attachment 43 located at the farthest end can move within a specified range, for example... Figure 1 The movement is within the usual range of Re or the extended range of Ra shown in the figure.

[0040] The plurality of actuators include a boom cylinder, a stick cylinder, and a remote accessory cylinder that respectively rock the boom 41, the stick 42, and the remote accessory 43. The boom cylinder and the stick cylinder are hydraulic cylinders that include a cylinder body and a piston rod.

[0041] exist Figure 1 In the posture shown by solid lines, the lower traveling body 20 is positioned on a horizontal ground surface S. The boom cylinder is fully extended, maximizing the undulation angle of the boom 41 relative to the upper rotating body 30. The stick cylinder is fully retracted, maximizing the rotation angle of the stick 42 relative to the boom 41. The distal auxiliary device cylinder is fully extended, maximizing the rotation angle of the distal auxiliary device 43 relative to the boom 41. In this posture, the distal auxiliary device cylinder retracts conversely, thereby achieving... Figure 1 As shown by the double-dotted line, the rotation angle of the distal auxiliary device 43 relative to the boom 41 is minimized.

[0042] The range of movement Ra refers to the range that the distal attachment 43, i.e., the tip of the bucket, can reach through the respective rocking motions of the boom 41, the stick 42, and the distal attachment 43. The extended range of movement Re refers to the range that, when... Figure 1 When the standard length stick 42 shown is replaced with a longer stick than the stick 42, the bucket tip can reach the range of motion of the boom 41, the stick 42, and the distal attachment 43. Regarding the height direction, both the (normal) travel range Ra and the extended travel range Re extend from a position above the uppermost part of the cab 31 to a position below the lowermost part of the cab 31. Furthermore, the extended travel range Re extends forward, downward, and backward beyond the travel range Ra. The rear boundary of the travel range Ra is set to be forward of the front surface guard 36 by a certain distance, so that when the stick 42 is replaced with the longer stick, the bucket tip will not interfere with the cab 31. Regarding the width direction of the upper rotating body, as... Figure 3As shown, viewed from the front of the cab 31, the right end of the travel range Ra is located on the left side, i.e., the inner side, of the support device 50, and the rear end Ra of the travel range Ra is located on the front side of the support device 50. The right boundary of the travel range Ra is positioned upwards from the top surface guard 39 by a certain distance, so that the tip of the bucket does not interfere with the cab 31. Depending on the type of distal attachment 43 installed at the distal end of the boom 42, the travel ranges Ra and Re will vary. However, as long as the distal attachment 43 recommended for use on the boom 42 is adopted, the travel range of the distal attachment 43 is set to be positioned forwards from the front surface guard 36 by a certain distance and upwards from the top surface guard 39 by a certain distance, so that the distal attachment 43 does not interfere with the cab 31.

[0043] Next, refer to Figure 2A , Figure 2B , Figure 3 Figure 5 to Figure 7 , Figure 8A and Figure 8B The support device 50 is described below. Figure 6 In the middle, the support device 50 is shown with a solid line, while the top wall 34 is shown with a double-dotted line.

[0044] The supporting device 50 is used to support the information acquisition device, thereby enabling at least one information acquisition device to be installed on the main body of the construction machinery 10. In this embodiment, it can be installed on the upper rotating body 30. In this embodiment, the at least one information acquisition device includes multiple cameras, namely, a first camera S1, a second camera S2, and a third camera S3. The first to third cameras S1, S2, and S3 are digital cameras or other shooting devices used to capture images of the area around the construction machinery 10. The first to third cameras S1, S2, and S3 can also be stereo cameras.

[0045] The support device 50 includes a retaining portion and a support member 54. The retaining portion includes a retaining engagement member 51, a left axle support member 52, and a right axle support member 53. The retaining engagement member 51, the left axle support member 52, and the right axle support member 53 are fixed to the cab 31 by bolts and nuts, thereby forming the retaining portion connected to the cab 31 and used to retain the support member 54. The left axle support member 52 and the right axle support member 53 axially support the support member 54, allowing the support member 54 to... Figure 2B and Figure 3 The upper position shown in the figure and Figure 5B and Figure 6The cameras can rotate between the lower positions shown in the diagram. The support member 54 supports the plurality of cameras S1 to S3 and is held in the holding portion.

[0046] As will be described in detail later, the retaining engagement member 51 refers to a member that can be detachably engaged with the support member 54 when the support member 54 is in the upper and lower positions, respectively. The retaining engagement member 51 integrally comprises a base plate portion 51a, a first retaining engagement portion 51b, a second retaining engagement portion 51c, a left side plate portion 51d, a right side plate portion 51e, and a back plate portion 51f. The base plate portion 51a extends along the upper edge of the front surface protector 36 in the width direction (left-right direction) of the upper rotating body and is fixed to the upper edge. The left side plate portion 51d and the right side plate portion 51e extend upward from the left and right ends of the base plate portion 51a, respectively, and protrude upward beyond the top wall 34. The back plate portion 51f is connected to the rear edges of the left side plate portion 51d and the right side plate portion 51e, respectively, so as to connect the rear edges of the left side plate portion 51d and the right side plate portion 51e in the width direction of the upper rotating body. The first retaining engagement portion 51b and the second retaining engagement portion 51c are fixed to the inner side surface of the left side plate portion 51d.

[0047] The left shaft support member 52 and the right shaft support member 53 are rotatably supported at both ends of the shaft portion 55 of the support member 54. That is, the left shaft support member 52 and the right shaft support member 53 constitute a shaft support portion for rotatably supporting the support member 54.

[0048] like Figure 6 and Figure 7 As shown, the left shaft support member 52 integrally comprises a base plate portion 52a and a side plate portion 52b. The base plate portion 52a extends along the left edge of the top wall 34 in the front-rear direction of the upper rotating body and is fixed to the front end of the left edge by bolts. The side plate portion 52b protrudes upward from the outer edge, i.e., the left edge, of the base plate portion 52a at a position to the left of the top surface protector 39, and protrudes forward beyond the front wall 35.

[0049] The right-axis support member 53 has a base plate portion and a side plate portion. The base plate portion is fixed to the right side portion of the retaining and engaging member 51 in the width direction of the upper rotating body. The side plate portion protrudes upward and rearward from the base plate portion beyond the retaining and engaging member 51.

[0050] like Figure 3As shown, the retaining portion, including the retaining engagement member 51, the left axle support member 52, and the right axle support member 53, is positioned to the left of the front center relative to the cab 31, so that the retaining portion is located outside the movement range Ra of the distal accessory 43 in the width direction of the upper rotating body. Furthermore, the support device 50 is positioned outside the movement range Ra in the front-rear direction of the upper rotating body, such that even when the member with the maximum lateral width is mounted on the stick 42 as the distal accessory 43 and the left boundary of the movement range Ra of the distal accessory 43 is located at the outermost edge (i.e., the left side), the support device 50 including the retaining portion will not interfere with the distal accessory 43.

[0051] On the other hand, the support member 54 includes the shaft portion 55, the base portion 58, the retaining engagement portion 59a, and the camera support portion 60.

[0052] The shaft portion 55 is composed of a shaft-like member, such as a tube member, that extends integrally along the width direction of the upper rotating body. This shaft portion 55 is rotatably supported by the left shaft support member 52 and the right shaft support member 53. The shaft portion 55 includes a left-end shaft portion 55b and a right-end shaft portion 55c as its two ends, and an intermediate shaft portion 56 located between the left-end shaft portion 55b and the right-end shaft portion 55c. The left-end shaft portion 55b and the right-end shaft portion 55c are located on a common axis of rotation extending along the width direction of the upper rotating body, and are rotatably supported by the left-end shaft support member 52 and the right-end shaft support member 53 such that the entire support member 54 can rotate about this axis of rotation between the upper and lower positions.

[0053] The left-end shaft portion 55b is supported on the left shaft support member 52 in such a way that it can rotate about the rotation axis corresponding to the central axis of the left-end shaft portion 55b. Similarly, the right-end shaft portion 55c is supported on the right shaft support member 53 in such a way that it can rotate about the rotation axis corresponding to the central axis of the right-end shaft portion 55c.

[0054] like Figure 6 and Figure 8BAs shown, the intermediate shaft portion 56 includes an axial portion 56a, a left radial portion 56b, and a right radial portion 56c. The axial portion 56a extends along an axial direction parallel to the rotation axis, i.e., the width direction of the upper rotating body, at a position away from the rotation axis in a direction orthogonal to the rotation axis, i.e., the rotation radius direction. The left radial portion 56b connects the left end of the axial portion 56a and the inner end (right end) of the left-end shaft portion 55b in the rotation radius direction. The right radial portion 56c connects the right end of the axial portion 56a and the outer end (right end) of the right-end shaft portion 55c in the rotation radius direction.

[0055] Affixed to the left radial portion 56b Figure 6 The handle portion 57 is shown. For example, the handle portion 57 is rectangular and protrudes forward from the left radial portion 56b. Through the handle portion 57, the operator who climbs onto the footrest (not shown in the figure) of the upper rotating body 30 can grasp the handle portion 57 and easily rotate the entire shaft portion 55, that is, can change the position of the support member 54 between the upper position and the lower position.

[0056] Upward-opening notches 52d and 53d are formed on the left shaft support member 52 and the right shaft support member 53, respectively. The notches 52d and 53d are arranged in a consistent manner when viewed from the width direction of the upper rotating body. The notches 52d and 53d are groove-shaped and have a width approximately the same as the diameter of the left-end shaft portion 55b and the right-end shaft portion 55c. The left-end shaft portion 55b and the right-end shaft portion 55c are inserted into the notches 52d and 53d from above, respectively, and are axially supported by the left shaft support member 52 and the right shaft support member 53 at their lower ends. The distal ends of the left-end shaft portion 55b and the right-end shaft portion 55c protrude outwards (i.e., to the left and right) beyond the left shaft support member 52 and the right shaft support member 53, and flanges 55d and 55f are fixed to these distal ends, respectively. The flanges 55d and 55f have a length and width dimension that are larger than the width of the notches 52d and 53d, thereby preventing the shaft portion 55 from detaching from the left shaft support member 52 and the right shaft support member 53 in the axial direction (width direction of the upper rotating body).

[0057] like Figure 6As shown, flanges 55d and 55f each have bolt holes 55j and 55i located at a certain distance downward from the axis of rotation. The bolt holes 55j and 55i extend through flanges 55d and 55f along their thickness direction, i.e., the width direction of the upper rotating body, allowing bolts used to fix flanges 55d and 55f to the left shaft support member 52 and the right shaft support member 53, respectively, to pass through the bolt holes 55j and 55i. The left shaft support member 52 has a pair of threaded holes 55k, and bolts passing through the bolt holes 55j of flange 55d can be threaded into these holes. Similarly, the right shaft support member 53 has a pair of threaded holes 55l, and bolts passing through the bolt holes 55i of flange 55f can be threaded into these holes.

[0058] The front threaded hole 55k of the pair of threaded holes 55k is formed in a position such that a bolt inserted from the outside into the bolt hole 55j of the flange 55d is threaded into the front threaded hole 55k, thereby fixing the flange 55d and the left end shaft portion 55b to the left shaft support member 52 when the support member 54 is in the upper position. Similarly, the rear threaded hole 55k of the pair of threaded holes 55k is formed in a position such that a bolt inserted from the outside into the bolt hole 55j of the flange 55d is threaded into the rear threaded hole 55k, thereby fixing the flange 55d and the left end shaft portion 55b to the left shaft support member 52 when the support member 54 is in the lower position.

[0059] The front threaded hole 55l of the pair of threaded holes 55l is formed in a position such that a bolt inserted from the outside into the bolt hole 55i of the flange 55f is threaded into the front threaded hole 55l, thereby fixing the flange 55f and the right end shaft portion 55c to the right shaft support member 53 when the support member 54 is in the upper position. Similarly, the rear threaded hole 55l of the pair of threaded holes 55l is formed in a position such that a bolt inserted from the outside into the bolt hole 55i of the flange 55f is threaded into the rear threaded hole 55l, thereby fixing the flange 55f and the right end shaft portion 55c to the right shaft support member 53 when the support member 54 is in the lower position.

[0060] Alternatively, the bolts can be pulled out from the bolt holes 55i and 55j, and the left shaft portion 55b and the right shaft portion 55c can be pulled upward along the notches 52d and 53d respectively, thereby removing the shaft portion 55 and even the support member 54 containing the shaft portion 55 from the left shaft support member 52 and the right shaft support member 53.

[0061] The base 58 is the portion fixed to the shaft 55 and used to support the camera support 60. The base 58 has a fixing portion 58a and a supporting portion 58d. Figure 6 As shown, with the axial portion 56a and the right end shaft portion 55c of the shaft portion 55 passing through the fixing portion 58a along the width direction of the upper rotating body, the fixing portion 58a is fixed to the shaft portion 55 in a manner that it rotates integrally with the shaft portion 55. The support portion 58d has a flat upper surface so that when the support member 54 is located... Figure 2B In the position shown above, the support 58d is parallel to the ground surface S of the engineering machinery 10, that is, it is approximately horizontal, and the base 58 is fixed to the intermediate shaft 56.

[0062] The camera support 60 is fixed to the support 58d in an upright position. The camera support 60 can also be fixed to the support 58d in a manner that allows its relative position to the base 58 to change in the width direction of the upper rotating body. In this embodiment, as... Figure 3 As shown, the right side portion 58e of the support 58d is located near the movement range Re, and the camera support 60 is fixed at this right side portion 58e.

[0063] The camera support 60 includes a base plate portion 64, an erecting portion 65, and a plurality of mounting base portions, including a first mounting base portion 61, a second mounting base portion 62, and a third mounting base portion 63. The base plate portion 64 is fixed to the upper surface of the support portion 58d in a state of overlapping with it. The erecting portion 65 is erected from the base plate portion 64. The first mounting base portion 61 and the second mounting base portion 62 protrude forward from the upper end and middle section of the erecting portion 65, respectively. The third mounting base portion 63 extends downward from the front end of the base plate portion 64.

[0064] In this embodiment, the first to third mounting portions 61, 62, and 63 have front ends with different slopes, and the first camera S1, the second camera S2, and the third camera S3 can be mounted on these front ends. Specifically, the front end of the upper first mounting portion 61 faces obliquely upward, the front end of the middle second mounting portion 62 faces obliquely downward with a small slope, and the front end of the lower third mounting portion 63 faces obliquely downward with a larger slope than that of the second mounting portion 62. Therefore, the camera support portion 60 can support the first to third cameras S1 to S3 in an arrangement along the vertical portion 64 and facing different directions.

[0065] like Figure 8B As shown, the retained engagement portion 59a is connected to the intermediate shaft portion 56 via a relay shaft 59b, and can selectively engage with the first retaining engagement portion 51b and the second retaining engagement portion 51c, respectively. The relay shaft 59b extends radially from the axial portion 56a of the intermediate shaft portion 56, and the retained engagement portion 59a is fixed at the distal end of the relay shaft 59b. On the other hand, on the retaining engagement member 51, the first retaining engagement portion 51b and the second retaining engagement portion 51c are arranged such that the second retaining engagement portion 51c is located below the first retaining engagement portion 51b. In detail, the first retaining engagement portion 51b and the second retaining engagement portion 51c are configured such that the entire support member 54 is fixed in the upper position by the engagement of the retained engagement portion 59a with the first retaining engagement portion 51b; and the entire support member 54 is fixed in the lower position by the engagement of the retained engagement portion 59a with the second retaining engagement portion 51c.

[0066] Bolt holes capable of mating are formed in the retaining engagement portion 59a, the first retaining engagement portion 51b, and the second retaining engagement portion 51c. At the engagement position between the retaining engagement portion 59a and the first retaining engagement portion 51b, by passing a bolt through the bolt holes in both portions, the retaining engagement portion 59a can be fastened to the first retaining engagement portion 51b using the bolt and a nut threaded onto the bolt.

At the position where the retained engagement portion 59a engages with the second retained engagement portion 51c, by passing a bolt through the bolt holes of the retained engagement portion 59a and the second retained engagement portion 51c, the retained engagement portion 59a can be fastened to the second retained engagement portion 51c using the bolt and a nut threaded with the bolt. Thus, the support member 54 is fixed to... Figure 5A , Figure 5B and Figure 6 The lower position is shown in the diagram. Further, with the support member 54 held in the upper position, by passing through... Figure 6 The bolts after the bolt holes 55j and 55i of the flanges 55d and 55f shown are threaded into the threaded holes 55k and 55l on the front side of the left shaft support member 52 and the right shaft support member 53, thereby fixing the shaft portion 55 of the support member 54 to the left shaft support member 52 and the right shaft support member 53. Similarly, with the support member 54 held in the lower position, the shaft portion 55 can be fixed to the left shaft support member 52 and the right shaft support member 53 by threading the bolts after passing through the bolt holes 55i and 55j into the threaded holes 55k and 55l on the rear side of the left shaft support member 52 and the right shaft support member 53.

[0067] Figure 2B The upper position shown is applicable to the use of the construction machinery 10. That is, when the construction machinery 10 is used for operation, the support member 54 is held in the upper position by the retaining part. The upper position refers to the position where the support member 54 is fixed by the engagement of the retained engaging part 59a with the first retaining engaging part 51b. Figure 2B In the diagram, the height of the front end of the first mounting base 61 is indicated by a dashed line Ha, which is also the height of the uppermost part of the support member 54 located at the upper side. The first camera S1, fixed to the first mounting base 61, is located at a position higher than the uppermost part. In this embodiment, the support member 54 supports the first to third cameras S1 to S3 respectively at the uppermost part of the engineering machinery body including the upper rotating body 30 at the upper side. In this embodiment, they are supported at a position higher than the top wall 34 or the top protective member 39, thereby ensuring good visibility and a wide field of view for each of the first to third cameras S1, S2, and S3.

[0068] The support member 54, located at the upper position, supports the first camera S1 in a forward-facing and upward-facing posture, supports the second camera S2 in a forward-facing and downward-facing posture, and supports the third camera S3 in a forward-facing and downward-facing posture with a greater slope than the second camera S2. This enables... Figure 1 The fields of view T1 to T3 of the first to third cameras S1 to S3 shown in the figure are continuously connected to each other, thus forming a panoramic image extending vertically. The shooting data corresponding to the fields of view T1 to T3 ensured in this way is transmitted to the outside of the engineering machinery 10 by a transmitting device (not shown) mounted on the engineering machinery 10, and received by a receiving device (not shown) located at a position away from the engineering machinery 10.

[0069] exist Figure 4 The display screens U1, U2, and U3, schematically shown in the diagram, display the captured data received by the receiving device, corresponding to the fields of view T1 to T3, respectively. The display screens U1, U2, and U3 are... Figure 4 The diagram shows the structural elements of the remote operation device 101, which is located away from the construction machinery 10, for example, in an office building used to manage the construction machinery 10.

[0070] The remote operation device 101 also includes a control device facing the displays U1, U2, and U3. The control device includes multiple remote operation components 102 and a remote control seat 103. The multiple remote operation components 102 are positioned in front of the remote control seat 103, and the operator 100, seated at the remote control seat 103, applies operations to the multiple remote operation components 102 to remotely operate the construction machinery 10. The multiple remote operation components 102 and... Figure 2A The plurality of operating components 32 within the cab 31 shown also include operating levers and travel levers for receiving rotational operations, and pedals may also be provided at the base or lower end of at least a portion of the operating levers and travel levers. After generating a command signal corresponding to the operation applied to the plurality of remote operating components 102, it is sent to the construction machinery 10, thereby enabling the operator 100 to remotely operate the construction machinery 10. The operator 100, seated in the remote control seat 103, can obtain the same field of vision T1, T2, T3 as when seated in the control seat 33 within the cab 31, through the images displayed on the displays U1, U2, U3.

[0071] The first to third cameras S1 to S3 capture images of the surroundings at a certain period, for example, 10 to 500 ms, and generate capture data. This capture data is continuously sent to the remote operating device 101 and displayed on the displays U1 to U3. In this way, the capture data is visualized in real time. This allows the operator 100 to operate the construction machinery 10 and perform prescribed tasks through the multiple remote operating components 102 without entering the cab 31.

[0072] On the other hand, the lower position shown in Figure 5 is suitable for transporting the construction machinery 10. When the construction machinery 10 is loaded onto a truck such as a low-chassis trailer and transported, the working mechanism 40 is positioned in a transport posture, for example, as shown in Figure 5. In this transport posture, the boom 41 is folded down, and the stick 42 and the distal attachment 43 contact or approach the ground surface S of the construction machinery 10 along the lower surface of the boom 41, while the distal attachment 43 is folded and inserted between the upper boom 41 and the lower stick 42. Alternatively, in this transport posture, the distal attachment 43 may also contact the ground surface S together with the stick 42. In the transport posture illustrated in Figure 5, the stick 42 is held under the boom 41, hence it is also referred to as a holding posture.

[0073] The lower position refers to the position where the support member 54 is fixed by engaging the retaining engagement portion 59a with the second retaining engagement portion 51c. Figure 5B In the diagram, the height of the rear end of the upright portion 65 is indicated by a dashed line La, which represents the height of the uppermost part of the support member 54 located on the lower side. Figure 5A As shown, the uppermost portion is located higher than the uppermost portion 41b of the boom 41 in the transport posture. In this embodiment, as indicated by the dotted line La, the support member 54 supports the first to third cameras S1 to S3 at a position lower than the uppermost portion of the support member 54 at the lower position. Therefore, regardless of whether the first to third cameras S1 to S3 are mounted on the first to third mounting portions 61 to 63, the transport height of the construction machinery 10 is the height of the uppermost portion indicated by the dotted line La. Thus, since the lower position is suitable for transporting the construction machinery 10, i.e., when the construction machinery 10 is not used, it is not a problem for the first to third cameras S1 to S3 supported by the support member 54 at the lower position to be positioned downwards than the upper position.

[0074] As described above, according to the engineering machinery 10 of this embodiment, when the first to third cameras S1 to S3 are used, by setting the support member 54 to the upper position, a good field of view T1 to T3 for the first to third cameras S1 to S3 is ensured; while when the first to third cameras S1 to S3 are not used, especially when transporting the engineering machinery 10, by setting the support member 54 to the lower position, it is not necessary to remove the first to third cameras S1 to S3 and the support member 54 from the upper rotating body 30, and the transport height of the engineering machinery 10 can be reduced.

[0075] Specifically, according to the support device 50 of this embodiment, the support member 54 is axially supported by the left axis support member 52 and the right axis support member 53 of the retaining part in a manner that allows rotation about the rotation axis, thereby enabling the position of the support member 54 to be changed between the upper and lower positions with a simple structure.

[0076] Furthermore, according to the support device 50 of this embodiment, the support member 54 has the retaining engagement portion 59a, which is located at a certain distance away from the rotation axis, and the retaining portion has: a first retaining engagement portion 51b, which engages with the retaining engagement portion 59a in a detachable manner, thereby retaining the support member 54 in the upper position; and a second retaining engagement portion 51c, which engages with the retaining engagement portion 59a in a detachable manner, thereby retaining the support member 54 in the lower position. Therefore, the support member 54 can be stably retained in the upper position and the lower position, respectively.

[0077] Furthermore, according to the support device 50, by passing a bolt through the bolt hole 55j formed on the flange 55d of the left end shaft portion 55b of the support member 54 and threading it into one of the pair of threaded holes 55k of the left shaft support member 52, the left end shaft portion 55b can be fixed to the left shaft support member 52; similarly, by passing a bolt through the bolt hole 55i formed on the flange 55f of the right end shaft portion 55c of the support member 54 and threading it into either of the pair of threaded holes 55l of the right shaft support member 53, the right end shaft portion 55c can be fixed to the right shaft support member 53. Thus, the support member 54 can be more stably fixed at the upper and lower positions, respectively.

[0078] Furthermore, according to the engineering machinery 10 of this embodiment, the uppermost part of the support member 54 located in the lower position is positioned higher than the uppermost part 41b of the boom 41 in the transport posture illustrated in FIG5. Therefore, the height of the uppermost part can be utilized, i.e. Figure 5B The height indicated by the dashed line Ha in the middle is used to easily manage the overall transport height of the engineering machinery 10 in the transport posture.

[0079] Furthermore, according to the engineering machinery 10 of this embodiment, the retaining engagement member 51, the left shaft support member 52, and the right shaft support member 53 constituting the retaining part are connected to the cab 31 of the upper rotating body 30. Moreover, the upper position of the support member 54 is directly above the cab 31. Therefore, the first to third cameras S1 to S3 supported by the support member 54 can all capture images of the front of the cab 31 with a good field of view.

[0080] Furthermore, according to the engineering machinery 10 of this embodiment, the support device 50 is positioned outside the movement range of the remote attachment 43. Therefore, regardless of the operation of the remote attachment 43, interference with the support device 50 by the remote attachment 43 can be prevented. Additionally, sand, mud, rocks, etc., falling from the boom 41, the stick 42, and the remote attachment 43 can be prevented from contacting the support device 50 and the first to third cameras S1 to S3.

[0081] Furthermore, according to the engineering machinery 10 of this embodiment, the retaining engagement member 51, which is part of the retaining part, is supported on the front surface protection member 36 that covers the front surface of the cab 31. Therefore, the support device 50 can be arranged in front of the cab 31 with a simple structure.

[0082] Furthermore, according to the engineering machinery 10 of this embodiment, the support member 54 supports multiple information acquisition devices, namely the first to third cameras S1 to S3. Therefore, the support member 54 and the multiple information acquisition devices can move integrally between the upper and lower positions. Additionally, the information acquisition device is not limited to a camera; it can also be a sensing device that measures the distance from the sensing device to the object. Furthermore, the multiple information acquisition devices supported on the support member may also include the camera and the sensing device.

[0083] Furthermore, when the information acquisition device is the sensing device, the transmitting device included in the construction machinery 10 according to this embodiment, that is, the transmitting device for outputting image data captured by the first to third cameras S1 to S3 to the outside of the construction machinery 10, can also be configured to transmit the measurement data measured by the sensing device to the remote operation device 101.

[0084] Furthermore, according to the engineering machinery 10 involved in this embodiment, such as Figure 2B As shown, in the lower position, the support member 54 is located forward of the corner 35c formed between the top wall 34 and the front wall 35 of the cab 31. Accordingly, the support member 54 can be lowered to the lower position without interfering with the top wall 34 and the top surface protection member 39.

[0085] according to Figure 8B The structure shown indicates that the support member 54 includes the retained engagement portion 59a, and the retaining portion includes a first retaining engagement portion 51b and a second retaining engagement portion 51c that can respectively engage with the retained engagement portion 59a. However, it is also possible that the support member 54 includes a first retaining engagement portion and a second retaining engagement portion located respectively away from the rotation axis, and the retaining portion includes retaining engagement portions that selectively engage with the first and second retaining engagement portions in a detachable manner. For example, as... Figure 8B As shown, with the support member 54 in the lower position, the first retaining engagement portion and the second retaining engagement portion are respectively positioned on the support member 54 corresponding to the first retaining engagement portion 51b and the second retaining engagement portion 51c. In this case, it is preferable that the retaining engagement portion is positioned on the retaining engagement member 51, for example, corresponding to the first retaining engagement portion 51b. This retaining engagement portion engages with the first retaining engagement portion in a detachable manner, thereby holding the support member 54 in the upper position, and engages with the second retaining engagement portion in a detachable manner, thereby holding the support member 54 in the lower position.

[0086] Below, refer to Figures 9 to 11 The second embodiment of the present invention will now be described. Figures 9 to 11 The second embodiment shows a support device 70, which includes a retaining part 71 and a support member 72.

[0087] The retaining part 71 includes Figure 11The diagram shows a pair of left axle support portions 71b and right axle support portions 71c. These two portions are arranged spaced apart in the same width direction as the cab 31 according to the first embodiment, i.e., the width direction of the upper rotating body. The left axle support portion 71b includes a pair of left and right ears that are fixed to the left side frame of the front surface protector 36 of the cab 31, protruding forward from the left side frame. Similarly, the right axle support portion 71c also includes a pair of left and right ears that are fixed to the right side frame of the front surface protector 36, protruding forward from the right side frame.

[0088] The support member 72 includes a pair of left shaft portions 55B and right shaft portions 55C, a pair of left arms 73b and right arms 73c, a crossbeam 74, a support column 66, and a camera support portion 60.

[0089] The left shaft portion 55B and the right shaft portion 55C are both horizontally extending cylindrical shapes, and are respectively held in the left shaft support portion 71b and the right shaft support portion 71c in a manner that allows them to rotate about a horizontal axis. Specifically, the left shaft portion 55B includes two ends of the pair of ears on the left shaft support portion 71b and a middle portion located between the pair of ears in a rotatable manner. Similarly, the right shaft portion 55C includes two ends of the pair of ears on the right shaft support portion 71c and a middle portion located between the pair of ears in a rotatable manner.

[0090] The paired left arm 73b and right arm 73c extend from the left shaft portion 55B and right shaft portion 55C respectively in the direction of rotation radius, that is, in a direction orthogonal to the axial direction of the left shaft portion 55B and right shaft portion 55C, and are respectively capable of rocking about the left shaft portion 55B and right shaft portion 55C. Specifically, the left arm 73b has a base end and a distal end on its opposite side, the base end being connected to the middle portion of the left shaft portion 55B in a manner that is integrally rotatable with the left shaft portion 55B. Similarly, the right arm 73c has a base end and a distal end on its opposite side, the base end being connected to the middle portion of the right shaft portion 55C in a manner that is integrally rotatable with the right shaft portion 55C.

[0091] The crossbeam 74 includes a plate extending along the width direction of the cab 31, i.e., the width direction of the upper rotating body, and is connected at the distal end of the paired left arm 73b and right arm 73c. ​​Specifically, the crossbeam 74 has a left end connected to the distal end of the left arm 73b and a right end connected to the distal end of the right arm 73c. ​​The lengths of the left arm 73b and right arm 73c and the angle of the crossbeam 74 relative to the left arm 73b and right arm 73c are set such that the crossbeam 74 can be moved by the rocking motion of the paired left arm 73b and right arm 73c. Figure 9 The upper horizontal position shown in the middle and Figure 10 and Figure 11 The crossbeam 74 moves between the forward spanning positions shown in the diagram. The upper spanning position corresponds to the upper side position of the support member 72, where the crossbeam 74 spans the cab 31 above the top wall 34 along the width direction of the upper rotating body. The forward spanning position corresponds to the lower side position of the support member 72, where the crossbeam 74 spans the cab 31 in front of the front wall 35 along the width direction of the upper rotating body.

[0092] The support column 66 extends outward from the central portion of the upper rotating body of the cross member 74 in the width direction and supports the camera support portion 60. Specifically, the support column 66 has a base end fixed to the central portion of the cross member 74 and a distal end on the opposite side thereto, and the camera support portion 60 is connected at the distal end.

[0093] The camera support portion 60 has the same shape and structure as the camera support portion 60 according to the first embodiment. That is, the camera support portion 60 according to the second embodiment includes the same base plate portion 64, upright portion 65, first mounting base portion 61, second mounting base portion 62, and third mounting base portion 63 as those in the first embodiment. The base plate portion 64 is connected to the distal end of the support column 66 in a posture that allows the upright portion 65 to extend further from the distal end of the support column 66. The first to third mounting base portions 61 to 63 support the first to third cameras S1 to S3 in the same manner as in the first embodiment. Specifically, in Figure 9As shown in the upper position, the first mounting part 61 supports the first camera S1 in a forward and upward orientation, the second mounting part 62 supports the second camera S2 in a forward and downward orientation, and the third mounting part 63 supports the third camera S3 in a forward and downward orientation with a greater slope than the second camera S2.

[0094] When the construction machinery 10 is in operation, the support member 72 is set to... Figure 9 The upper position is shown in the diagram. In this upper position, the support member 72 supports the first to third cameras S1 to S3 in a suitable posture and position for use, thereby enabling the first to third cameras S1 to S3 to... Figure 1 The views T1 to T3 shown in the diagram provide a similarly good view of the front of the construction machinery 10. This is especially true when the construction machinery 10 is not in operation, particularly when transporting it. Figure 10 As indicated by arrow A1, the support member 72 tilts forward from the upper position, thereby moving to... Figure 10 and Figure 11 The lower position is shown in the diagram. The orientation of the first to third cameras S1 to S3, supported by the support member 72 located in the lower position, is not suitable for use, but since the construction machinery 10 is not in operation, there is no problem. Thus, in the second embodiment, similarly to the first embodiment, the support member 72 swings along the fore-and-aft direction of the cab 31, thereby switching between the upper and lower positions.

[0095] The support member 72 can be held in the upper and lower positions by its own weight, or it can be fixed in these positions by bolts or other fixing units.

[0096] According to the support device 70 of the second embodiment, the left axis support portion 71b and the right axis support portion 71c constituting the holding portion 71 also support the support member 72 in a manner that allows the position of the support member 72 to be selectively changed between the upper and lower positions. Accordingly, it is not necessary to remove the first to third cameras S1 to S3 from the first to third mounting portions 61 to 63 respectively, nor is it necessary to remove the support member 72 from the construction machinery 10, thus reducing the transport height of the construction machinery 10.

[0097] According to the support device 70 of the second embodiment, in Figure 10As shown in the diagram, in the lower position, the support member 72 is generally located in front of the corner 35c between the front wall 35 and the top wall 34 of the cab 31. Accordingly, the support member 72 can be lowered to the lower position below the top wall 34 without interfering with the top wall 34 and the top surface protection member 39. Alternatively, in this lower position, only a specific portion of the member 72 can be positioned in front of the corner 35c; in this case, at least that specific portion can be lowered in the lower position.

[0098] Below, refer to Figure 12 and Figure 13 The third embodiment of the present invention will now be described. Figure 12 and Figure 13 The support device 75 according to the third embodiment is shown. The support device 75 includes a retaining part and a support member 77.

[0099] The retaining portion includes a shaft support 76, which is the same as the left shaft support 71b and right shaft support 73c involved in the second embodiment. This shaft support 76 is not fixed to the front wall 35 of the cab 31, but is fixed to the top wall 34. Specifically, the shaft support 76 protrudes upward from the middle position of the top wall 34 in the front-rear direction of the upper rotating body.

[0100] The support member 77 includes a shaft portion 55, an arm 78, a pillar 66, and a camera support portion 60, which are respectively corresponding to the left shaft portion 55b and right shaft portion 55c, the left arm 73b and right arm 73c, the pillar 66, and the camera support portion 60 of the support member 72 according to the second embodiment.

[0101] The shaft portion 55 is held in the shaft support portion 76 in a manner rotatable about a horizontal axis, specifically, the horizontal axis is an axis extending along the width direction of the upper rotating body. The arm 78 has a base end and a distal end on its opposite side, the base end being rotatably connected to the shaft portion 55 integrally with it, and the arm 78 is axially supported in the shaft support portion 76 in a manner rotatable about the shaft portion 55. Specifically, the arm 78 is capable of... Figure 12 As shown, the front collapse position along the top wall 34 and the front collapse position as shown Figure 13 It sways between rearward tilted positions extending obliquely backward from the shaft portion 55 as shown, the front tilted position corresponding to the upper position of the support member 77, and the rear tilted position corresponding to the lower position of the support member 77.

[0102] The support column 66 and the camera support portion 60 are connected to the arm 78 in such a way that they are erected on the distal end, i.e., the front end, of the arm 78 located in the forward-folded position. Specifically, the camera support portion 60 of this embodiment includes the same upright portion 65 and the first to third mounting portions 61 to 63 as those of the second embodiment. The camera support portion 60 is connected to the distal end of the arm 78 via the support column 66 in such a way that the upright portion 65 and the support column 66 are substantially orthogonal to the arm 78. In the upper position, i.e., the position where the upright portion 65 is erected, the first to third mounting portions 61 to 63 are arranged sequentially from top to bottom and are connected to the upright portion 65 in a forward-projecting manner to support the first to third cameras S1 to S3, respectively.

[0103] When the construction machinery 10 is in operation, the support member 77 is set to... Figure 12 The upper position is shown. The first to third cameras S1 to S3 are supported at a higher position by the support member 77 located at the upper position, so as to have a... Figure 1 The field of view T1 to T3 shown in the figure have the same good field of view and are able to capture images of the front of the engineering machinery 10.

[0104] When the construction machinery 10 is not in operation, especially when the construction machinery 10 is being transported, such as Figure 13 As indicated by arrow A2, the operator moves the support member 77 backward around the axis 55 from the upper position, thereby moving it to... Figure 13 The lower position is shown in the diagram. In this lower position, the pillar 66 of the camera support 60 extends obliquely downward or downward from the distal end of the arm 78, which extends obliquely upward rearward, toward the rear side of the cab 31, and at least the first to third mounting portions 61 to 63 on the support member 77 are located behind the corner 38c between the top wall 34 and the rear wall 38 of the cab 31. Although the orientation of the first to third cameras S1 to S3 is not suitable for use, there is no problem because the construction machinery 10 is not in operation. Thus, in the third embodiment, similarly to the first and second embodiments, the support member 77 swings along the fore-and-aft direction of the cab 31, thereby switching between the upper position and the lower position. However, in the first and second embodiments, the support members 54 and 72 are tilted forward to move from the upper position to the lower position, while in the third embodiment, the support member 77 is tilted backward to move from the upper position to the lower position.

[0105] According to the support device 75 of the third embodiment, the shaft support portion 76 constituting the holding portion also rotatably supports the support member 77, and the position of the support member 77 can be selectively changed between the upper position and the lower position La. Therefore, it is not necessary to remove the first to third cameras S1 to S3 from the first to third mounting portions 61 to 63, nor is it necessary to remove the support member 77 from the construction machinery 10, so that the transport height of the construction machinery 10 can be reduced.

[0106] Furthermore, according to the support device 75 of the third embodiment, in Figure 13 As shown in the diagram, in the lower position, the distal portion of the support member 77 is located behind the corner 38c between the top wall 33 and the rear wall 38 of the cab 31. Therefore, the lower position of the support member 77 can be lowered without interfering with the top wall 34. Furthermore, in the lower position, the portion of the support member 77 located behind the corner 38c is not limited to the distal portion; it can be other portions. For example, all or almost all of the support member 77 in the lower position can be located behind the corner 38c.

[0107] Below, refer to Figure 14 and Figure 15 The fourth embodiment of the present invention will now be described. Figure 14 and Figure 15 The fourth embodiment shows a support device 80, which includes a retaining part 81 and a support member 82.

[0108] The retaining part 81 is fixed to the top wall 34 of the cab 31 and holds the support member 82 in a manner that allows it to slide vertically. The support member 82 includes not only the same camera support 60 as the camera support 60 described in the first embodiment, but also a retained part 83. The retained part 83 extends downward in a straight line from the camera support 60 and passes through the retaining part 81 in a vertical direction. The retaining part 81 can be switched between a state that allows the retained part 83 to slide vertically relative to the retaining part 81 and a state that prevents the sliding and fixes the support member 82 containing the retained part 83 in any position.

[0109] like Figure 14 As shown, the retaining part 81 can fix the supporting member 82 in the upper position by retaining the lower end of the retained part 83. Furthermore, as... Figure 15As shown by arrow A3, the retaining part 81, after allowing the operator to slide the retained part 83 downward from the upper position, retains the middle part of the retained part 83 in the vertical direction, such as... Figure 15 As shown, the support member 82 can be fixed at a lower position than the upper position. At this lower position, the lower end of the held portion 83 needs to descend to the lower position of the top wall 34, but the manner in which this descent is permitted is not limited. For example, a hole can be formed in the top wall 34 to allow the lower portion of the held portion 83 to pass through the hole, or the holding portion 81 can be configured to hold the held portion 83 at a position away from the top wall 34 along the width direction of the upper rotating body.

[0110] According to the support device 80 of the fourth embodiment, the retaining part 81 can also be capable of... Figure 14 The upper position shown in the figure and Figure 15 The support member 82 is held in a sliding manner between the lower positions shown in the figure, thereby reducing the transport height of the engineering machinery 10 without removing the first to third cameras S1 to S3 from the first to third mounting bases 61 to 63 or the support member 82 from the engineering machinery 10.

[0111] Below, refer to Figure 16 and Figure 17 The fifth embodiment of the present invention will now be described. Figure 16 and Figure 17 The fifth embodiment shows a support device 85, which includes a frame 86 constituting a retaining portion and a support member 87.

[0112] The frame 86 includes a beam 86a and a pair of feet 86b and 86c. The pair of feet 86b and 86c are fixed to the left and right edges of the top wall 34 of the cab 31 in such a way that they stand upright on the left and right edges. The beam 86a extends above the top wall 34 along the width direction of the upper rotating body and connects to the upper end of the pair of feet 86b and 86c.

[0113] The support member 87 includes a shaft portion 55, a support arm 67, a camera support portion 60, and multiple mounting portions 61, 62, and 63. The camera support portion 60 also includes a first mounting portion 61, a second mounting portion 62, and a third mounting portion 63, similar to the camera support portion 60 in the first embodiment.

[0114] The shaft portion 55 is cylindrical, and its central axis runs along the front-rear direction of the upper rotating body, i.e. Figure 16 and Figure 17The shaft 55 extends in the depth direction of the paper surface and is held in the middle portion of the beam portion 86a of the frame 86 in the width direction of the upper rotating body, in a manner that allows it to rotate about the central axis. The middle portion constitutes a shaft support portion, which axially supports the support member 87 in a manner that allows it to rotate about a rotation axis corresponding to the central axis of the shaft 55. The support arm 67 connects the camera support portion 60 and the shaft portion 55 to each other, thereby allowing the camera support portion 60 to rock about the rotation axis that is the central axis of the shaft portion 55 in the width direction of the upper rotating body. Specifically, the support arm 67 has a base end fixed to the shaft portion 55 and a distal end on the opposite side thereof. The camera support portion 60 is connected to the distal end of the support arm 67 in a manner in which the third mounting portion 63, the second mounting portion 62, and the first mounting portion 61 are arranged sequentially from the side near the distal end of the support arm 67.

[0115] By rocking the support arm 67, the position of the support member 87 can be selectively switched. Figure 16 The upper position shown in the figure and Figure 17 The lower position is shown in the diagram. When the construction machinery 10 is in operation, the support member 87 is positioned in the upper position, where the camera support 60 is located above the top wall 34 of the cab 31, and the first to third mounting seats 61 to 63 are arranged in this order from top to bottom. When the construction machinery 10 is not in operation, such as... Figure 17 As indicated by arrow A5, the operator rotates the support member 87 downwards from the upper position around the shaft 55 and moves it to the lower position. In the lower position, the support member 87 is in a tilted position along the beam 86a of the frame 86, and the first to third mounting portions 61 to 63 of the camera support 60 are horizontally arranged at a height adjacent to the top wall 34. Thus, according to the fifth embodiment, the support member 87 is tilted laterally in the lower position along the width direction of the cab 31, i.e., the width direction of the upper rotating body.

[0116] According to the support device 85 of the fifth embodiment, the axial support portion of the frame 86 supports the support member 87 in a manner that allows it to rotate around the axial portion 55. This allows the position of the support member 87 to be selectively switched between the upper position and the lower position. As a result, the transport height of the engineering machinery 10 can be reduced without removing the first to third cameras S1 to S3 from the first to third mounting portions 61 to 63 or removing the support member 87 from the engineering machinery 10.

[0117] Below, refer to Figures 18 to 20 The sixth embodiment of the present invention will now be described. Figures 18 to 20 The sixth embodiment shows a support device 90, which includes a retaining part 91 and a support member 93.

[0118] The retaining part 91 includes Figure 20 The diagram shows a pair of left track members 91b and right track members 91c, which are respectively fixed to the left and right edges of the front wall 35 of the cab 31. The left track members 91b and right track members 91c extend in the vertical direction.

[0119] The support member 93 includes a guided portion 92, a support column 68, and a camera support portion 60. The guided portion 92 extends along the width direction of the cab 31, i.e., the width direction of the upper rotating body, and includes two ends respectively held in the left track member 91b and the right track member 91c, namely, a left end 92b and a right end 92c. The left end 92b and the right end 92c are respectively engaged with the left track member 91b and the right track member 91c in a manner that allows them to be guided along the left track member 91b and the right track member 91c, i.e., in a manner that allows them to slide in the vertical direction. The left track member 91b and the right track member 91c include fixing units (not shown in the figure) for fixing the left end 92b and the right end 92c in any position. The fixing unit can be switched between: a state where the fixing of the left end 92b and the right end 92c is released and the guided part 92 is allowed to slide along the left track member 91b and the right track member 91c in the vertical direction; and a state where the sliding is prevented and the guided part 92 is fixed at least in the upper and lower positions respectively. The support column 68 is fixed in a vertical manner at the central part, extending upward from the central part in the width direction of the upper rotating body of the guided part 92. The camera support 60, like the camera support 60 in the first embodiment, includes a first mounting base 61, a second mounting base 62, and a third mounting base 63 capable of mounting the first camera S1, the second camera S2, and the third camera S3 respectively. The first to third mounting bases 61 to 63 are fixed to the upper end of the support column 68 in this order from top to bottom.

[0120] When the engineering machinery 10 according to the sixth embodiment is in operation, the support member 93 is fixed to the upper position by the fixing unit, that is... Figure 18 The position shown in the diagram. In the upper position, the first to third mounting portions 61 to 63 are held higher than the top wall 34 of the cab 31. On the other hand, when the construction machinery 10 is not in operation, the fixing unit is released, and, as shown in the diagram... Figure 19As indicated by arrow A6, the operator lowers the support member 93 and secures it to the lower position. Figure 19 and Figure 20 The position shown in the figure. In the lower position, the first to third mounting portions 61 to 63 are held lower than the top wall 34.

[0121] According to the support device 90 of the sixth embodiment, the left track member 91b and the right track member 91c of the holding part 91 hold the guided part 92 of the support member 93 in a manner that allows it to slide in the vertical direction between the upper and lower positions. As a result, the transport height of the engineering machinery 10 can be reduced without removing the first to third cameras S1 to S3 from the first to third mounting parts 61 to 63 or the support member 93 from the engineering machinery 10.

[0122] Below, refer to Figure 21 The seventh embodiment of the present invention will now be described. Figure 21 The following are important parts of the support device 50A according to the seventh embodiment, except for Figure 6 Apart from the specific shapes of the left axle support member 52 and the right axle support member 53 shown, the support device 50A has the same configuration as the support device 50 according to the first embodiment. The support device 50A, like the support device 50, has a left axle support member 52 and a right axle support member 53; however, the left axle support member 52 and the right axle support member 53 have rearward-opening notches 82d and 83d respectively, instead of upward-opening notches. Specifically, the notches 82d and 83d are inclined in a manner that increases in height towards the rear. Viewed from the width direction of the cab 31, i.e., the width direction of the upper rotating body, the notches 82d and 83d are arranged in a manner that aligns with their positions. The left end shaft portion 55b and the right end shaft portion 55c of the shaft portion 55 are inserted into the notches 82d and 83d from the rear, respectively, and, as... Figure 21 As shown, the left axis support member 52 and the right axis support member 53 can be engaged at the ends, i.e. the front ends, of the notches 82d and 83d.

[0123] Since the notches 82d and 83d slope forward and downward towards their ends, the support member 54 containing the shaft portion 55 can be stably supported when the operator inserts the left shaft portion 55b and the right shaft portion 55c into the notches 82d and 83d and when they are removed.

[0124] The embodiments of the present invention have been described above with reference to the accompanying drawings; however, the present invention is not limited to the embodiments shown in the drawings. Various modifications or alterations can be made to the embodiments shown in the drawings within the same or equivalent scope as the present invention. For example, a portion of the configuration may be extracted from one of the above embodiments, and other portions may be extracted from other of the above embodiments, and then these extracted configurations may be combined.

[0125] For example, the at least one information acquisition device involved in this invention is not limited to devices that cooperate with each other to perform wide-angle panoramic shooting, such as the first to third cameras S1 to S3. For example, the information acquisition device may be selected from LiDAR that measures the surrounding distance using optical methods, sensing devices that measure the surrounding distance using ultrasonic waves, and other sensing devices. The height position of the support member involved in this invention can be appropriately set. Furthermore, the retaining part involved in this invention may also be a member capable of fixing the support member at at least one intermediate position between the upper position and the lower position.

[0126] When the at least one information acquisition device includes multiple information acquisition devices, the multiple information acquisition devices are not limited to devices arranged in a vertical direction like the first to third cameras S1 to S3. The support member involved in this invention can also be a member that supports the multiple information acquisition devices in a manner that arranges them along the width direction of the upper rotating body. That is, the arrangement of the multiple mounting portions in the support member for respectively supporting the multiple information acquisition devices is not limited.

[0127] The support device of the present invention may further include a drive device for driving the support member to change its position. The drive device may include, for example, an actuator such as an electric or hydraulic working cylinder, and a mechanism for converting the action of the actuator into the action of the support member, such as a rack and pinion or a gear mechanism. Furthermore, the support device may also include an operating member operated by an operator to actuate the drive device, such as a button, switch, or lever. The operating member may be located within the cab 31 adjacent to the plurality of operating members 32, or it may be located outside the cab 31. Through the operating member, the operator can change the height of the support member without having to climb to a higher position where the retaining part and the support member exist.

[0128] The support device of the present invention may further include a control unit for controlling the operation of the drive device. The control unit may also be configured to monitor the status of the construction machinery, for example, the status of the construction machinery's engine being stopped. Figure 4The control unit determines situations such as communication interruption or termination during remote operation, and the loading of the construction machinery onto a transport truck, and automatically activates the drive unit. Alternatively, the control unit may be configured to activate the drive unit based on operations performed by the operator on a switch installed on the construction machinery 10, operations performed on a terminal carried by the operator, or operations performed by the operator sitting at the control seat of the remote operation device on the switch of the remote operation device. This improves the efficiency of operations related to the transportation of the construction machinery.

[0129] The auxiliary devices for construction machinery involved in this invention may be as follows: as described in the auxiliary device 43 above, an auxiliary device that moves within the range of motion Ra according to the operation of the operating member 32 by an operator entering the cab 31 of the construction machinery 10; or, an auxiliary device that moves within the range of motion Ra according to the operation of the remote operating member 102 in the remote operating device 101 outside the construction machinery by an operator; or, an auxiliary device that moves within the range of motion Ra according to automatic or autonomous driving that does not require the operation of an operator.

[0130] As described above, a support device for engineering machinery and information acquisition equipment is provided. The engineering machinery can be equipped with information acquisition equipment such as cameras. When transporting the engineering machinery, the transportation height of the engineering machinery can be reduced without removing the information acquisition equipment.

[0131] The construction machinery includes: a construction machinery body; a holding part connected to the construction machinery body; and a support member held in the holding part and supporting at least one information acquisition device for acquiring information about the surroundings of the construction machinery. The holding part is configured to selectively hold the support member between an upper position and a lower position below the upper position.

[0132] For example, when the information acquisition device is used, the retaining part holds the support member in the upper position, thereby enabling the information acquisition device to acquire information in a good condition. When the information acquisition device is not used, for example, the support member can be held in the lower position, which is lower than the upper position. Accordingly, the transport height of the construction machinery can be reduced without removing the information acquisition device from the main body of the machinery.

[0133] The retaining portion includes, for example, a shaft support portion, which can also be configured to retain the support member, allowing the support member to rotate between the upper and lower positions about a rotation axis. By allowing rotation of the support member, the retaining portion facilitates easy switching of the support member's position between the upper and lower positions.

[0134] The retaining part can retain the support member by its own weight or by a suitable fixing unit. For example, when the retaining part includes the shaft support part, it can also be that the support member includes a retaining engagement part located at a certain distance away from the rotation axis, and the retaining part includes: a first retaining engagement part that engages with the retaining engagement part in a detachable manner to hold the support member in the upper position; and a second retaining engagement part that engages with the retaining engagement part in a detachable manner to hold the support member in the lower position. Alternatively, it can be that the support member includes a first retaining engagement part and a second retaining engagement part, each located at a certain distance away from the rotation axis, and the retaining part includes a retaining engagement part. The retaining engagement portion engages with the first retaining engagement portion in a detachable manner, thereby holding the support member in the upper position, and engages with the second retaining engagement portion in a detachable manner, thereby holding the support member in the lower position.

[0135] The construction machinery further includes: a boom connected to the main body of the construction machinery in a manner capable of rocking up and down; and a stick connected to the distal end of the boom in a manner capable of rocking up and down, and capable of mounting distal attachments for operation. Preferably, the uppermost part of the support member in the lower position is positioned higher than the uppermost part of the boom in the transport posture. The transport posture refers to the posture in which the boom is tilted down and the stick contacts or approaches the ground contact area of ​​the construction machinery along the lower surface of the boom. Accordingly, the transport height of the construction machinery can be easily managed using the upper position.

[0136] The position of the retaining part relative to the main body of the construction machinery can be arbitrarily set. Preferably, the retaining part is located at the front of the main body of the construction machinery. Furthermore, it is preferable that the retaining part is located at the upper part of the main body of the construction machinery. When the main body of the construction machinery includes a cab with an operator's seat, the retaining part can be positioned directly above the cab. The main body of the construction machinery includes a lower traveling body and an upper rotating body, the upper rotating body being connected to the lower traveling body in a manner that allows it to rotate above the lower traveling body; when the upper rotating body includes the cab, it is preferable that the retaining part is connected to the cab, and the supporting member is positioned at the upper position and held directly above the cab. This allows information acquisition devices supported on the supporting member, such as digital cameras or other imaging devices, to acquire good information from the cab, for example, to capture images with a good field of view.

[0137] When the construction machinery further includes a protective component for covering the front surface of the cab, the protective component can also support at least a portion of the retaining portion. This allows the retaining portion to be located further forward of the construction machinery body.

[0138] When the cab includes a front wall, a rear wall located behind the front wall, and a top wall connected to the upper ends of the front wall and the rear wall respectively, preferably, in the lower position, at least a portion of the support member is located forward of the corner formed between the front wall and the top wall, or rearward of the corner formed between the rear wall and the top wall. This allows at least a portion of the support member to be lower than the top wall in the lower position, enabling the construction machinery to have a smaller height dimension.

[0139] The construction machinery further includes: a boom mounted on the main body of the construction machinery in a manner that allows it to rock vertically; a stick connected to the boom in a manner that allows it to rock vertically; and a remote attachment mounted on the stick and used for operation. Preferably, the retaining part and the supporting member are located outside the movement range of the remote attachment. Accordingly, regardless of how the remote attachment moves, the retaining part and the supporting member can be prevented from interfering with the remote attachment. Furthermore, it can prevent work objects, such as sand, mud, or rocks, from detaching from the remote attachment from contacting the retaining part and the supporting member.

[0140] The at least one information acquisition device may also include multiple information acquisition devices. In this case, the support member supports the multiple information acquisition devices, thereby enabling the acquisition of a wider variety of information with a simple configuration.

[0141] Preferably, the construction machinery further includes a transmitting device that outputs the information acquired by the information acquisition device to an external location. Through the transmitting device, the information can be acquired remotely from the construction machinery, thereby enabling, for example, the operation of the construction machinery remotely, or the storage of the information on a server.

[0142] Alternatively, the retaining portion may also retain the support member in a manner that allows it to move up and down at least between the upper and lower positions. For example, the retaining portion may include a track extending in a vertical direction, and the support member may include a guided portion that engages with the track in a manner that allows it to be guided along the track. By guiding the guided portion via the track, the support member including the guided portion can move vertically between the upper and lower positions.

[0143] Furthermore, a support device is provided for supporting an information acquisition device on the upper rotating body of an engineering machine, the engineering machine including a lower traveling body and an upper rotating body, the upper rotating body being connected to the lower traveling body in a manner capable of rotating relative to the lower traveling body, the information acquisition device being used to acquire information about the surroundings of the engineering machine. The support device includes: a retaining part connected to the upper rotating body; and a support member held in the retaining part and used to support the information acquisition device, wherein the retaining part is configured to selectively hold the support member in an upper position and a lower position below the upper position.
