Description

Technical Field

[0001] This invention relates to the field of mining equipment, specifically to a safety operation trolley for supporting broken roadways with an adjustable roof spacing. Background Technology

[0002] In related technologies, before anchoring a roadway, a support net is installed on the roadway wall. The support net plays a protective role during the anchoring operation. However, due to the low strength of the support net, it can only provide simple protection. When the surrounding rock of the roadway becomes unstable, the support net cannot stop the falling rock blocks, thus posing a safety hazard. Summary of the Invention

The protective frame and the telescopic frame are movably connected along the spacing direction of the support frame. When avoiding the protective position, the protective frame is arranged opposite to any of the support frames.

[0011] In some embodiments, the safety operation trolley for supporting broken roadways with an adjustable canopy with adjustable spacing further includes the support net, which is detachably connected to the support frame.

[0012] In some embodiments, the support frame is an arc-shaped plate, and / or the protective frame is an arc-shaped plate.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is for reference. Figure 1 and Figure 2 This invention describes a safety operation trolley for supporting broken roadways with an adjustable canopy based on an embodiment of the present invention.

[0022] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a safety operation trolley body device 1, a telescopic frame 2, a support frame 3, and a protective frame 4 for supporting broken roadways with an adjustable canopy.

[0023] The telescopic frame 2 is mounted on the vehicle body device 1, and can be optionally mounted on the vehicle body device 1 as follows: Figure 1 The top shown. The telescopic frame 2 is located at one end opposite to the vehicle body assembly 1 (as shown). Figure 1 The top of the telescopic frame 2 shown is provided with at least two support frames 3 and several protective frames 4. The telescopic frame 2 can be optionally arranged along the top of ... Figure 1 The vertical extension and retraction shown can drive the optional lifting and lowering movement of the support frame 3 and the protective frame 4.

[0024] At least two support frames, 3 optional, along such Figure 1 The front and rear directions are arranged at intervals, and together with the telescopic frame 2 and the vehicle body device 1, they form a working space. The working space is used to accommodate workers, who can carry out anchoring operations.

[0025] At least two support frames 3 are positioned away from the outer wall of the work space to support the support net 5. Driven by the telescopic frame 2, the support net 5 is raised and lowered to press against the roadway wall and continuously support it.

[0026] Several protective frames 4 are located within the work space; in other words, several protective frames 4 are located on at least two support frames 3. Figure 1 As shown below.

[0027] The protective frame 4 is movably connected to the telescopic frame 2, allowing it to move to a protective position relative to the space between it and the adjacent support frame 3, and to avoid a protective position. Optionally, when the protective frame 4 is in the protective position, it is positioned within the space between the support frame 3. Figure 1 Directly below. When the protective frame 4 is in the protective position, it can stop rocks from passing through the gap between adjacent support frames 3 and the support net 5, thereby improving the protective effect. When the protective frame 4 is out of the protective position, workers can carry out anchoring operations in the gap between adjacent support frames 3.

[0028] It should be noted that since the anchoring operation is carried out through the support net 5, the support net 5 is fixed to the roadway wall after the anchoring operation.

[0029] This invention discloses a safety operation trolley for supporting broken roadways with an adjustable canopy. The telescopic frame 2 can drive the support frame 3 to move so as to press the support net 5 carried by the support frame 3 against the roadway wall and continuously support the support net 5, thereby providing strong protection for personnel in the work space. The protective frame 4 can move to the protective position to stop rocks passing through the support net 5, further improving the protective effect. When the protective frame 4 avoids the protective position, it can carry out anchoring operations in the space between adjacent support frames 3 with strong safety.

[0030] In some embodiments, such as Figure 1 As shown, the working space is used to install anchoring devices, which can be selected from anchor drilling rigs, etc. The anchoring devices can be connected to the vehicle body device 1, for example, through a robotic arm, or they can be held by the operator.

[0031] The gap between adjacent support frames 3 is used for anchoring operations when the protective frame 4 avoids the relatively set protective position. When anchoring operations need to be carried out in the gap between adjacent support frames 3, the protective frame 4 that is relatively set in the gap is first moved to a position that avoids the protective position. Then, the anchoring operation is carried out in the gap using the anchoring device. After the anchoring operation is completed, the anchoring device is retracted, and then the previously moved protective frame 4 is moved back to the protective position that is relatively set in the gap. When there are multiple gaps between adjacent support frames 3, anchoring operations can be carried out in multiple gaps between adjacent support frames 3 in sequence. When anchoring operations are carried out in one of the gaps between adjacent support frames 3, the other relatively set protective positions in the gaps between adjacent support frames 3 are equipped with corresponding protective frames 4, thereby providing sufficient protection for personnel in the work space.

[0032] It should be noted that the anchoring operation may include at least one of the following steps: drilling anchor holes, cleaning anchor holes, installing anchor bolts, and grouting.

[0033] In some embodiments, such as Figure 1 As shown, the protective frame 4 is arranged along the interval direction of the support frame 3 (e.g., Figure 1 (As shown in the front and back directions) are set to at least two, and the anchoring device can pass through the gap space between adjacent protective frames 4 to reach the gap space between adjacent support frames 3.

[0034] When anchoring operations are required in the space between adjacent support frames 3, the protective frame 4 of the space to be anchored is first moved to a position that avoids the protective position in the forward and backward direction. At this time, the space to be anchored is located between the moved protective frame 4 and another adjacent protective frame 4 on the other side in the forward and backward direction. The anchoring device passes through the space between the two protective frames 4 to reach the space to be anchored, so that the anchoring operation can be carried out.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, both the support frame 3 and the protective frame 4 are configured to run along the edge of the wall. Figure 1 The strips extending in the left and right directions are arranged in parallel. The protective frame 4 is parallel to the support frame 3 when it is in the protective position and when it is avoiding the protective position.

[0036] The protective frame 4 and the telescopic frame 2 are arranged along the interval direction of the support frame 3 (e.g., Figure 1The protective frame 4 is movably connected in the front-back direction (as shown). Optionally, the top left and right sides of the telescopic frame 2 are provided with first guide grooves 21 extending in the front-back direction. The left end of the protective frame 4 is located in the first guide groove 21 on the left and can move along the first guide groove 21 on the left. The right end of the protective frame 4 is located in the first guide groove 21 on the right and can move along the first guide groove 21 on the right, so that the protective frame 4 can move left and right, thereby being able to be in the protective position and avoid the protective position.

[0037] When the protective frame 4 is avoiding the protective position, it is positioned opposite to any support frame 3. In other words, when the protective frame 4 is avoiding the protective position, it is located directly below any support frame 3. It can be selected to be located directly below the support frame 3 adjacent to the protective position of the protective frame 4, so as to make the structure of the safety operation trolley for supporting broken roadways with adjustable spacing compact, which is conducive to reducing the volume and making it easy to move in the roadway.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, a safety operation trolley for supporting broken roadways with an adjustable roof spacing also includes a support net 5. The support net 5 is detachably connected to the support frame 3. Optionally, the support net 5 and the support frame 3 are detachably connected by connectors such as bolts, buckles, or binding wires.

[0039] In the use of a safety operation trolley for supporting broken roadways with an adjustable roof spacing, the vehicle body 1 moves to a designated position, the telescopic frame 2 is first at the loading height position, and then the support net 5 is connected to the outer wall of at least two support frames 3. After that, the telescopic frame 2 rises to the working height position to press the support net 5 against the roadway wall. Then, the anchoring operation is carried out sequentially on the several spaces formed between adjacent support frames 3 to be anchored. After the anchoring operation is completed on the several spaces formed between adjacent support frames 3 to be anchored, the support net 5 is separated from the support frame 3. The support net 5 remains on the roadway wall, and the support frame 3 moves down with the telescopic frame 2 so that the vehicle body 1 can move along the roadway to the next designated position.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame 3 is an optional upward-protruding arc-shaped plate. The arc shape of the support frame 3 matches the arc shape of the roadway top, so that the support net 5 is pressed into the wall of the roadway top in an arc shape and fits, thereby achieving a good protective effect and avoiding affecting the anchoring operation.

[0041] In some embodiments, such as Figure 1 and Figure 2As shown, the protective frame 4 is an optional upward-protruding arc-shaped plate, so that when the protective frame 4 is in the protective position, there is a small gap between it and the space between the adjacent support frame 3, thereby achieving a good protective effect and preventing personnel movement and the operation of the anchoring device in the work space.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame 3 and the telescopic frame 2 are arranged along the spacing direction of the support frame 3 (e.g., Figure 1 (As shown in the front and back directions) can be movably connected.

[0043] Optionally, the top left and right sides of the telescopic frame 2 are provided with second guide grooves 22 extending in the front-back direction. The left end of the support frame 3 is located in the second guide groove 22 on the left and can move along the second guide groove 22 on the left. The right end of the support frame 3 is located in the second guide groove 22 on the right and can move along the second guide groove 22 on the right, so that the support frame 3 can move left and right. On the one hand, by adjusting the position of the support frame 3, the support net 5 can be better supported. On the other hand, by adjusting the position of the support frame 3, the width of the space between adjacent support frames 3 can be adjusted to ensure that anchoring operations can be carried out.

[0044] Optionally, when the telescopic frame 2 is at the loading height position, the position of the support frame 3 is adjusted, and then the support net 5 is connected to at least two support frames 3, the position of the support frame 3 remains unchanged before the support net 5 is separated from the support frame 3.

[0045] Optionally, the two first guide grooves 21 are located between the two second guide grooves 22 so that the protective frame 4 is located within the working space, in other words, the protective frame 4 is located below the support frame 3.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame 3 and the telescopic frame 2 are detachable. Optionally, the second guide groove 22 passes through the telescopic frame 2 in the front-to-back direction and forms a second opening at both the front and rear ends of the telescopic frame 2. The end of the support frame 3 in the left-to-right direction can be inserted into and detached from the second guide groove 22 through the second opening at the same end.

[0047] The number of support frames 3 connected to the telescopic frame 2 is adjustable, so that the corresponding number of support frames 3 can be set according to the anchor position at the top of the roadway and the model of the support net 5, so as to avoid the support net 5 collapsing due to insufficient number of support frames 3, and to avoid the anchor position being obscured due to excessive number of support frames 3.

[0048] The protective frame 4 and the telescopic frame 2 are detachable. Optionally, the first guide groove 21 extends through the telescopic frame 2 in the front-to-back direction and forms a first opening at both the front and rear ends of the telescopic frame 2. The end of the protective frame 4 in the left-to-right direction can be inserted into and detached from the first guide groove 21 through the first opening at the same end.

[0049] The number of protective frames 4 connected to the telescopic frame 2 is adjustable, so that the corresponding protective frames 4 are set according to the number of interval spaces formed between adjacent support frames 3, so as to avoid the protection gap caused by the insufficient number of protective frames 4, and to avoid the anchoring operation of the anchoring device being affected by the excessive number of protective frames 4.

[0050] Optionally, there may be multiple support frames 3 and multiple protective frames 4.

[0051] In some embodiments, such as Figure 2 As shown, the protective frame 4 has a first protrusion at each end along the left and right directions. The first guide groove 21 has a first slot on at least one side wall surface in the left and right directions. Optionally, both side walls have a first slot. The first protrusion is embedded in the first slot to restrict the ends of the protective frame 4 along the left and right directions within the corresponding first guide groove 21, so as to prevent the protective frame 4 from detaching from the slot at the top of the first guide groove 21.

[0052] The support frame 3 has a second protrusion at each end along the left and right directions. The second guide groove 22 has a second slot on at least one side wall in the left and right directions. Optionally, both side walls have a second slot. The second protrusion is embedded in the second slot to restrict the ends of the support frame 3 along the left and right directions within the corresponding second guide groove 22, so as to prevent the support frame 3 from disengaging from the slot at the top of the second guide groove 22.

[0053] In some embodiments, such as Figure 1 As shown, the telescopic frame 2 includes an end frame 23 and at least three telescopic actuators 24. The at least three telescopic actuators 24 are connected between the vehicle body assembly 1 and the end frame 23 to drive the end frame 23 to move toward and away from the vehicle body assembly 1. The telescopic actuators 24 may be four arranged along the four corners of a rectangle, or the telescopic actuators 24 may be arranged along... Figure 1 As shown in the vertical arrangement, the end frame 23 is connected to the top of four telescopic actuators 24 to move up and down under the synchronous drive of the four telescopic actuators 24. The telescopic actuators 24 can be hydraulic telescopic rods.

[0054] The end frame 23 connects two support frames 3 and several protective frames 4. Optionally, the end frame 23 is provided with a first guide groove 21 and a second guide groove 22. The end frame 23 can be rectangular to facilitate the support frames 3 and protective frames 4.

[0055] In some embodiments, such as Figure 1As shown, the telescopic frame 2 also includes telescopic members 25, and at least two adjacent telescopic actuators 24 are provided with a plurality of parallel telescopic members 25.

[0056] Optionally, such as Figure 1 As shown, the end frame 23 can be rectangular, and four telescopic actuators 24 can be selected and are correspondingly located at the four corners of the end frame 23. The left and right sides of the top of the end frame 23 are respectively connected to the support frame 3 and the protective frame 4 at their corresponding ends in the left and right directions. Multiple telescopic components 25 are provided between the two telescopic actuators 24 at the left end, and multiple telescopic components 25 are also provided between the two telescopic actuators 24 at the right end. The telescopic components 25 are arranged parallel to the telescopic actuators 24, and multiple telescopic components 25 located at the same end in the left and right directions are arranged at intervals in the front and back directions.

[0057] Thus, the telescopic component 25 forms a protective effect on the side of the telescopic frame 2 to protect the working space. Alternatively, the telescopic frame 2 can form a protective effect on the left and right sides of the working space. The front and rear sides of the telescopic frame 2 can be used for personnel and anchoring devices to enter and exit the working space.

[0058] The telescopic component 25 connects the vehicle body assembly 1 and the end frame 23, and is arranged along the direction of the adjacent telescopic actuators 24 (e.g., Figure 1 The telescopic component 25 (shown in the front-to-back direction) is movable, and it can extend and retract under the drive of the end frame 23.

[0059] Optionally, the bottom of the end frame 23 is provided with frame grooves extending in the front-rear direction on both the left and right sides. The top of the telescopic member 25 is engaged in the frame groove located at the same end in the left-right direction and can move back and forth along the frame groove. The top of the vehicle body device 1 is provided with vehicle body grooves 11 extending in the front-rear direction on both the left and right sides. The bottom of the telescopic member 25 is engaged in the vehicle body groove 11 located at the same end in the left-right direction and can move back and forth along the vehicle body groove 11, thereby allowing the telescopic member 25 to move between two adjacent telescopic actuators 24 in the front-rear direction. At the same time, the telescopic member 25 can move along the front-rear direction under the drive of the end frame 23. Figure 1 The telescopic mechanism extends and retracts in the vertical direction as shown to ensure that the telescopic frame 2 can be raised and lowered.

[0060] The telescopic component 25 is movable in the front-to-back direction. On the one hand, the position of the telescopic component 25 can be adjusted according to the location requiring protection to improve the protection effect. On the other hand, the working space is used to install anchoring devices. The anchoring devices can extend from the gap between adjacent telescopic components 25 to anchor the roadway sidewall. When no anchoring is being carried out, the gap between adjacent telescopic components 25 is too small to meet the size requirements for the extension of the anchoring devices. At this time, it mainly serves a protective function. When it is necessary to anchor a location on the roadway sidewall, the position of the telescopic component 25 is adjusted to increase the width of the gap between two adjacent telescopic components 25 to meet the size requirements for the extension of the anchoring devices. This gap is set opposite to the anchoring location on the roadway sidewall, so that anchoring can be carried out at that location.

[0061] Optionally, after anchoring the space between adjacent support frames 3, anchoring is also performed on the space between adjacent expansion joints 25 located below the space between adjacent support frames 3, so as to facilitate operation and achieve higher work efficiency.

[0062] The telescopic component 25 can be a telescopic plate.

[0063] In some embodiments, such as Figure 1 As shown, the telescopic frame 2 also includes a middle frame 26, which is located between the end frame 23 and the vehicle body device 1, and can be a rectangular frame.

[0064] Telescopic actuator 24 includes a fixed section and a telescopic section connected together, the telescopic section being relative to the fixed section along... Figure 1 The device is telescopic in the vertical direction. The fixed section is connected to the vehicle body device 1, and the telescopic section is connected to the end frame 23. Thus, the telescopic section drives the end frame 23 to move up and down.

[0065] The central frame 26 is connected to the fixed sections of at least three telescopic actuators 24. Optionally, the fixed sections of the four telescopic actuators 24 are respectively connected to the four corners of the central frame 26.

[0066] The central frame 26 is provided with a through-center sliding groove 27. Optionally, both the left and right ends of the central frame 26 are provided with central sliding grooves 27, and the central sliding grooves 27 extend along... Figure 1 The vertical direction extends through the middle frame 26 and is set along the as shown Figure 1 The telescopic member 25, which extends in the front-to-back direction, passes through the central groove 27 at the same end in the left-to-right direction and is movable along the central groove 27.

[0067] The stability of the telescopic frame 2 can be further improved by setting the middle frame 26.

[0068] In some embodiments, the vehicle body device 1 includes a platform and a tracked chassis. The platform is located on top of the tracked chassis and is used to form a working space and is provided with a vehicle body chute 11. When the operator is in the working space, he is on the platform. The tracked chassis is used to move the vehicle body device 1 along the roadway.
