[0009] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and duplicated descriptions will be omitted.

[0010] Fig. 1 is a left side view of a shovel 100 as an excavator according to one embodiment of the present invention. Fig. 2 is a right side view of the shovel 100 shown in Fig. 1.

[0011] In the following description, the X-axis, Y-axis, and Z-axis directions are directions perpendicular to one another, and typically, the X-axis and Y-axis directions are horizontal directions, and the Z-axis direction is vertical. The X-axis direction is the front-to-rear direction of the shovel 100, with the front side being the +X direction and the rear side being the -X direction. The Y-axis direction is the left-to-right width direction of the shovel 100, with the left side being the +Y direction and the right side being the -Y direction. The Z-axis direction is the height direction of the shovel 100, with the upper side being the +Z direction and the lower side being the -Z direction.

[0012] 1 and 2, the excavator 100 has a lower traveling body 1, a slewing mechanism 2, an upper rotating body 3, a boom 4, an arm 5, and a bucket 6. The upper rotating body 3 is rotatably mounted on the lower traveling body 1 via the slewing mechanism 2.

[0013] A cabin 10 serving as an operator's cab is provided at the front left side of the revolving frame 3F that forms the base of the upper revolving body 3. A door 11 for an operator to enter and exit the cabin 10 is provided on the left side of the cabin 10.

A bucket 6 as an end attachment is rotatably attached to the tip of the arm 5. The boom 4, arm 5, and bucket 6 constitute an excavation attachment, which is an example of an attachment. Instead of the bucket 6, another end attachment such as a breaker or a crusher may be attached to the tip of the arm 5.

[0016] Next, the cabin 10 will be further described with reference to Figures 3 and 4. Figure 3(a) is a left front perspective view of the cabin 10 showing a state in which the protective plate 200 is attached. Figure 3(b) is a right rear perspective view of the cabin 10 showing a state in which the protective plate 200 is attached. Figure 4(a) is a left front perspective view of the cabin 10 showing a state in which the protective plate 200 has been removed. Figure 4(b) is a right rear perspective view of the cabin 10 showing a state in which the protective plate 200 has been removed.

[0017] <Cabin> First, the configuration of the cabin 10 to which the protection plate 200 is attached will be described with reference to Figures 3 and 4. The cabin 10 has a bottom surface, a top surface, and side surfaces (front side surface, left side surface, right side surface, and rear side surface), and is formed in a substantially box shape.

[0018] As shown in Figure 4, a door 11 that can be opened and closed by a door hinge 12 is provided on the front side of the left side of the cabin 10. A door catch 13 is provided on the outer side surface of the door 11. In addition, a metal receiving bracket 14 is provided on the left side of the cabin 10, rearward of the door hinge 12. By fully opening the door 11 and engaging the door catch 13 with the metal receiving bracket 14, the door 11 can be held in the open position. A handrail 15 is provided on the upper left side of the cabin 10.

[0019] 4, windows 21 to 27 are provided on the side surfaces of the cabin 10. Specifically, an upper window 21 and a lower window 22 are provided on the front side surface of the cabin 10. A door 11 provided on the front side of the left side surface of the cabin 10 is provided with windows 23 and 24. A window 25 is provided on the rear side of the left side surface of the cabin 10. A window 26 is provided on the right side surface of the cabin 10. A window 27 is provided on the rear side surface of the cabin 10. The windows 21 to 27 are provided with window glass, and are configured so that an operator inside the cabin 10 can see the outside of the cabin 10 through the windows 21 to 27.

[0020] 3 and 4, a carrier 30 that functions as a storage section for storing the protection plate 200 is provided on the ceiling surface of the cabin 10. As shown in FIG. 3, the carrier 30 has beam members 31 to 34 and bosses 35 to 38.

[0021] The beam members 31, 32 are arranged with their longitudinal direction aligned with the front-to-rear direction (X direction) of the shovel 100, and are fixed to the ceiling surface of the cabin 10 with bolts or the like. Here, the beam members 31, 32 are arranged spaced apart in the left-to-right direction (Y direction), with the beam member 31 arranged on the left side of the ceiling surface of the cabin 10 and the beam member 32 arranged on the right side of the ceiling surface of the cabin 10. The beam members 31, 32 are formed, for example, by bending sheet metal into a substantially L-shape. The beam members 33, 34 are arranged with their longitudinal direction aligned with the left-to-right width direction (Y direction) of the shovel 100, and both ends are fixed to the beam members 31, 32. Here, the beam members 33, 34 are arranged spaced apart in the front-to-rear direction (X direction), with the beam member 33 arranged on the front side and the beam member 34 arranged on the rear side. The beam members 33, 34 are formed, for example, by bending sheet metal into a channel shape (groove shape). When the protection plates 200 (201 to 211) are stored in the carrier 30, the protection plates 200 (201 to 211) are stored in a stacked state on the beam members 33 and 34, as shown in FIG.

[0022] Bosses 35 to 38 are formed extending upward from the beam members 33 and 34. Here, the bosses 35 and 36 are arranged on the front beam member 33 to be spaced apart in the left-right width direction (Y direction), and the bosses 37 and 38 are arranged on the rear beam member 34 to be spaced apart in the left-right width direction (Y direction). When storing the protective plates 200 (201 to 211) in the carrier 30, the bosses 35 to 38 are inserted into engagement holes 320 (see FIG. 5, which will be described later) formed in the protective plates 200 (201 to 211), thereby positioning the protective plates 200 (201 to 211) stored in a stack on the beam members 33 and 34. It is preferable that the distance between the bosses 35 and 36 is different from the distance between the bosses 37 and 38, resulting in an asymmetrical arrangement. This allows the orientation and front / back of the protective plates 200 (201-211) to be uniquely determined when the protective plates 200 (201-211) are stacked and stored on the carrier 30. The bosses 35-38 are cylindrical, and the beam members 33, 34 have holes that communicate with the holes in the bosses 35-38. Nuts (not shown) are welded and fixed to the back sides of the beam members 33, 34 at positions that communicate with the bosses 35-38 and the holes in the beam members 33, 34. The holes in the bosses 35-38 may be female-threaded. After the protective plates 200 (201-211) are stacked and stored on the beam members 33, 34, the protective plates 200 (201-211) can be fixed on the carrier 30 by inserting bolts 40 into the holes in the bosses 35-38 and screwing the bolts 40 into nuts fixed below the bosses 35-38.

[0023] Further, mounting portions 51 (51a to 51r) and mounting portions 52 (52a to 52m) for mounting the protection plate 200 are provided on the side surfaces (front side surface, left side surface, right side surface, and rear side surface) of the cabin 10. Here, the mounting portions 51, 52 are provided at six locations (mounting portions 51a to 51f) on the front side surface of the cabin 10, at twelve locations (mounting portions 51g to 51i, mounting portions 52a to 52i) on the right side surface of the cabin 10, at ten locations (mounting portions 51j to 51q, mounting portions 52j to 51k) on the left side surface of the cabin 10, and at three locations (mounting portions 51r, mounting portions 52l to 51m) on the rear side surface of the cabin 10. The mounting portions 51 (51a to 51r) are formed by engaging members that engage with mounting holes 310 (311, 312, 313; see FIG. 5, which will be described later) of the protection plate 200, which will be described later. The mounting portions 52 (52a to 52m) have a bolt hole structure that screws onto a bolt (not shown) inserted into a mounting hole 310 (314, see FIG. 5, which will be described later) of the protection plate 200.

[0024] Next, the configuration of the protection plate 200 that is detachably attached to the cabin 10 and protects the side surface of the cabin 10 will be described with reference to FIGS. 3 and 4. FIG.

[0025] For example, after daily work at a site is completed, the excavator 100 may be left abandoned at the site. At this time, the operator removes the protective plate 200 from a storage unit (carrier 30) provided on the excavator 100 and attaches the protective plate 200 to the side of the excavator 100. Specifically, the protective plate 200 is attached so as to cover the windows 21 to 27 provided on the side of the cabin 10. The protective plate 200 is also attached so as to prevent the door 11 from being opened. This prevents the window glass provided on the windows 21 to 27 from being damaged by flying stones kicked up by other excavators or vehicles traveling on the site or by stones thrown at the excavator 100. The protective plate 200 also prevents people from entering the cabin 10. The protective plate 200 is also called a vandal cover or vandal guard. Before starting work, the operator removes the protective plate 200 from the side of the cabin 10 and stores the protective plate 200 in a storage unit (carrier 30) provided on the excavator 100.

[0026] The protective plate 200 has multiple protective plates 201 to 211. The protective plate 201 is a protective plate for covering the window 27 provided on the rear side of the cabin 10. The protective plates 202 to 205 are protective plates for covering the window 26 provided on the right side of the cabin 10. The protective plate 206 is a protective plate for covering the window 25 provided on the rear left side of the cabin 10. The protective plates 207 to 209 are protective plates for preventing the door 11 provided on the front left side of the cabin 10 from being opened and for covering the windows 23 and 24 provided on the door 11. The protective plate 207 has an opening 330 for avoiding interference with the door catch 13 formed to protrude from the outer side surface of the door 11 when the protective plate 207 is attached to the left side of the cabin 10. The protective plates 210 and 211 are protective plates for covering the windows 21 and 22 provided on the front side of the cabin 10. The protection plates 201 to 209 are formed of plate members. The protection plate 210 is formed by connecting two plate members with a hinge. The protection plate 211 is formed by bending a plate member along the shape of the front lower part of the cabin 10.

[0027] The configuration of the protection plates 201 to 211 will be described using the protection plate 204 as an example. FIG.

[0028] The protective plate 204 is provided with mounting holes 310 (311 to 314). In the example shown in FIG. 5, the mounting holes 311 to 313 engage with mounting portions 51 (51m to 51o) provided on the side of the cabin 10. Specifically, the mounting holes 311 to 313 have a shape that communicates with a large-diameter hole portion through which the head of the mounting portion 51 can be inserted, and a slotted hole portion that has a diameter smaller than that of the head of the mounting portion 51 and slightly larger than that of the shaft of the mounting portion. The mounting holes 314 are configured so that bolts (not shown) are inserted and screwed into mounting portions 52 (51j) provided on the side of the cabin 10, thereby preventing the protective plate 204 from being easily removed.

[0029] The protective plate 204 is also provided with engagement holes 320 (321 to 324) through which the bosses 35 to 38 are inserted when the protective plate 204 is housed in the carrier 30.

[0030] Furthermore, the protection plate 204 is provided with an attachment position graphic 410 corresponding to information indicating the attachment position when the protection plate 204 is attached to the side surface of the cabin 10. The attachment position graphic 410 is provided with a cabin shape graphic 411 indicating the shape of the cabin 10, and a position indication graphic 412 indicating the attachment position of the protection plate 204. In other words, the protection plate 204 has an attachment position information display area (attachment position information display unit) for displaying information indicating the attachment position when the protection plate 204 is attached to the side surface of the cabin 10. The attachment position graphic 410 is formed in the attachment position information display area.

[0031] In the example shown in FIG. 5 , the protection plate 204 is attached to the right side of the cabin 10, and therefore an attachment position graphic 410 for the protection plate 204 displays a schematic cabin-shaped graphic 411 of the cabin 10 as viewed from the right side. Furthermore, the protection plate 204 is attached to a position on the front lower side of the right side of the cabin 10, and therefore a position indication graphic 412 indicating the attachment position (front lower) of the protection plate 204 is displayed at a position corresponding to the cabin-shaped graphic 411. The cabin-shaped graphic 411 has a cabin-front shaped graphic corresponding to the cabin 10 as viewed from the front, a cabin-left rectangular shaped graphic corresponding to the cabin 10 as viewed from the left side, a cabin-right rectangular shaped graphic corresponding to the cabin 10 as viewed from the right, and a cabin-rear shaped graphic corresponding to the cabin 10 as viewed from the rear. The cabin-front shaped graphic is provided on the protection plates 210 and 211. The cabin-left rectangular shaped graphic is provided on the protection plates 206, 207, 208, and 209. The cabin right side shape figure is provided on protection plates 202, 203, 204, and 205. The cabin rear shape figure is provided on protection plate 201. In this way, cabin shape figure 411 is provided with a figure corresponding to the surface of cabin 10 on which protection plate 200 is to be placed. In addition, position indication figure 412 is provided with a hole (figure) that indicates at which position on the side surface of the cabin corresponding to cabin shape figure 411 protection plate 200 is to be attached.

[0032] Furthermore, the protective plate 204 is provided with a storage order graphic 420 corresponding to information indicating the storage order when the protective plate 204 is stored in the carrier 30. In other words, the protective plate 204 has a storage order information display area (storage order information display portion) for displaying information indicating the storage order when the protective plate 204 is stored in the carrier 30. The storage order graphic 420 is formed in the storage order information display area.

[0033] The mounting position graphic 410 and the storage order graphic 420 are arranged on the outer surface when the protective plate 200 is attached to the side surface of the cabin 10. This makes it easy to distinguish between the front and back of the protective plate 200 when attaching the protective plate 200 to the side surface of the cabin 10.

[0034] The mounting position graphic 410 and the storage order graphic 420 are displayed by arranging a plurality of through holes that penetrate the protective plate 200 in the plate thickness direction. By forming the through holes, it is possible to reduce processing costs. It is also possible to prevent the display from becoming invisible due to soiling or damage to the protective plate 200. Furthermore, the through holes allow light to pass through from the back side, thereby improving visibility. Note that the display is not limited to through holes, and the mounting positions and storage order may also be displayed by arranging a plurality of recesses or protrusions.

[0035] Furthermore, the attachment position figure 410 and the storage order figure 420 are disposed at diagonal positions on the protection plate 200. Specifically, as shown in Figures 3 and 5, the attachment position figure 410 is disposed at the upper right of the protection plate 200 (201 to 211), and the storage order figure 420 is disposed at the lower left of the protection plate 200 (201 to 211). In other words, the positional relationship between the attachment position figure 410 and the storage order figure 420 when the protection plate 200 (201 to 211) is viewed from the front is the same for all of the protection plates 200 (201 to 211). This makes it easy to determine the top-to-bottom and front-to-back orientations when attaching the protection plate 200 to the side of the cabin 10.

[0036] <Removal of the protection plate 200> Here, we will explain an example of the operator's work from the state in which the protective plate 200 is attached to the side of the cabin 10 (see Figure 3) to the state in which the protective plate 200 is removed and stored in the storage section (see Figure 4).

[0037] The operator passes through the step 3S from the front right side of the upper rotating body 3 and climbs up to the upper surface 3T of the upper rotating body 3. First, the operator removes the protective plate 201 attached to the rear side of the cabin 10 and places it on the carrier 30 so that the engagement holes 320 of the protective plate 201 are inserted into the bosses 35 to 38. Similarly, the operator removes the protective plates 202 to 205 attached to the left side of the cabin 10 and places them on the carrier 30 so that the engagement holes 320 of the protective plates 202 to 205 are inserted into the bosses 35 to 38.

[0038] The operator gets off the upper surface 3T of the upper rotating body 3 and moves to the left side of the cabin 10. The operator removes the protective plates 206 to 209 attached to the right side of the cabin 10 and places them on the carrier 30 so that the engagement holes 320 of the protective plates 202 to 205 are inserted into the bosses 35 to 38. The operator removes the protective plate 211 attached to the front side of the cabin 10, and then removes the protective plate 210. The operator then places the protective plate 210 on the carrier 30 so that the engagement holes 320 of the protective plate 210 are inserted into the bosses 35 to 38. Thereafter, the operator places the protective plate 211 on the carrier 30 so that the engagement holes 320 of the protective plate 211 are inserted into the bosses 35 to 38. In this way, the protective plate 211 having a bent shape is stored last. That is, the protective plates 201 to 211 are stacked on the carrier 30 in this order from the bottom up.

[0039] In this way, the operator stores the protection plates 200 in the order displayed in the storage order graphic 420. Then, the operator secures the protection plates 200 by inserting the bolts 40 into the holes in the bosses 35 to 38 and screwing the bolts 40 into the nuts fixed below the bosses 35 to 38. This allows the protection plates 200 to be stored in an appropriate manner.

[0040] <Installation of the protection plate 200> Next, an example of the operations of the operator from the state where the protection plate 200 is stored (see FIG. 4) to the state where the protection plate 200 is attached to the side surface of the cabin 10 (see FIG. 3) will be described.

[0041] The operator removes bolts 40 that are threadedly engaged with nuts (not shown) fixed below bosses 35 to 38. Here, protective plates 201 to 211 are stacked in this order from the bottom up on carrier 30. That is, protective plate 210 is stacked so as to be located below protective plate 211.

[0042] Next, the operator removes the protective plate 211 and the protective plate 210 from the storage section. The operator attaches the protective plate 210 to the upper front side of the cabin 10 according to the attachment position displayed on the attachment position graphic 410 of the protective plate 210. Specifically, bolts (not shown) are inserted into two attachment holes 310 provided on the upper side of the protective plate 210 and screwed into two attachment portions 52a, 52b provided on the upper side of the cabin 10. As a result, the protective plate 210 is supported by being suspended from the front side of the cabin 10. In addition, bolts (not shown) are inserted into two attachment holes 310 provided on the lower side of the protective plate 210 and partially screwed into two attachment portions 52c, 52d provided on the side of the cabin 10 to form an engaging member.

[0043] Next, the operator attaches the protection plate 211 to the lower front side of the cabin 10 in accordance with the attachment position displayed in the attachment position graphic 410 for the protection plate 211. Specifically, the operator overlaps a portion of the protection plate 210 so that the protection plate 210 is below the protection plate 211, and engages (hooks) bolts (not shown) that screw into the attachment portions 52c and 52d with two attachment holes 310 provided on the upper side of the protection plate 211. As a result, the protection plate 211 is supported by being suspended from the side of the cabin 10. Then, bolts (not shown) are inserted into the two attachment holes 310 provided on the lower side of the protection plate 211 and screwed into two attachment portions 52e and 52f provided on the side of the cabin 10. Then, the bolts that screw into the attachment portions 52c to 52f are tightened. As a result, the protection plates 210 to 211 are fixed to the side of the cabin 10.

[0044] Here, the protection plate 210 having the hinges is fixed to the four mounting portions 52a to 52d with bolts. This makes it possible to prevent the gap between the protection plate 210 and the window 21 from widening due to the protection plate 210 attached to the front surface of the cabin 10 moving by the hinges.

[0045] Similarly, the operator removes the protective plates 209 and 206 from the storage section. Then, the operator attaches the protective plate 209 to the upper front left side of the cabin 10 in accordance with the attachment position displayed on the attachment position graphic 410 of the protective plate 209. Specifically, the operator engages (hooks) the four attachment portions 51a to 51d provided on the upper side of the cabin 10 with the attachment holes 310 provided on the upper and lower sides of the protective plate 209, two of which are provided on each side. As a result, the protective plate 209 is supported by being hung from the side of the cabin 10.

[0046] Next, the operator attaches the protection plate 208 to the center of the front left side of the cabin 10 in accordance with the attachment position displayed on the attachment position graphic 410 of the protection plate 208. Specifically, the operator overlaps a portion of the protection plate 209 so that it is below the protection plate 208, and engages (hooks) the attachment portions 51c, 51d, which are engaged with the two attachment holes 310 provided on the underside of the protection plate 209, with the two attachment holes 310 provided on the upper side of the protection plate 208. As a result, the protection plate 208 is supported by being hung from the side of the cabin 10.

[0047] Next, the operator attaches the protection plate 207 to the lower front left side of the cabin 10 in accordance with the attachment position displayed on the attachment position graphic 410 for the protection plate 207. Specifically, the operator overlaps a portion of the protection plate 208 so that it is below the protection plate 207, and engages (hooks) two attachment portions 51e, 51f provided on the underside of the cabin 10 with two attachment holes 310 provided on the underside of the protection plate 207. As a result, the protection plate 207 is supported by being suspended from the side of the cabin 10.
