A ladder 6 used for cleaning, seating, maintenance, etc. of the packing box 5 is provided behind the driver's cab 3 and below the front side of the packing box 5 in the subframe 4. The dump truck 1 has a vehicle 2 based on a light truck, and the depth of the scaffolding 6a of the ladder 6 is shallow due to a vehicle width limitation or the like. In addition, a rib 5a processed to prevent slipping may be provided on the side surface of the packing box 5.

On the side surface of the subframe 4 immediately in front of the ladder 6, a wheel chock holder 10 capable of inserting and removing the wheel chock member 20 in the vertical direction is provided.

As shown in FIGS. 1A to 1C, the wheel chock holder 10 includes a holder frame 11 that is fixed to the subframe 4 by welding or the like. As shown in FIG. 1A, the holder frame 11 has a horizontal member 11a whose front and rear ends are bent downward and whose upper left and right back sides are welded to the subframe 4, and whose front and rear ends are bent outward to the left and right, and the upper end thereof. A vertical member 11b welded to the inner surface of the horizontal member 11a is provided. A housing portion 12 formed by bending a steel plate into a shape covering the wheel chock member 20 is welded to the vertical member 11b of the holder frame 11. The wheel chock member 20 is inserted into the holder frame 11 and the accommodating portion 12 from above and accommodated. The wheel chock member 20 is made of, for example, a resin molded product, and is sandwiched between the outer circumference of the tire and the ground to prevent the wheel from moving.

A pair of support members 13 are welded to the subframe 4 and the horizontal member 11a so as to sandwich the front and rear sides of the holder frame 11. The pair of support members 13 are rotatably supported by the rotated member 14 in the direction indicated by an arrow in FIG. 1A about a rotation shaft 15 composed of bolts or the like. The rotation shaft 15 is inserted through a through hole 13a (shown in FIG. 1C) of the support member 13. A block-shaped stopper portion 13b is welded to the support member 13 at a predetermined distance from the through hole 13a. A retaining member 16 made of an aluminum alloy or the like is attached to the rotated member 14 by a mounting screw 16a or the like. That is, the retaining member 16 is rotatably provided above the wheel chock holder 10 and is configured to cover the wheel chock member 20 from above and prevent the wheel chock member 20 from coming off at the accommodation position. The retaining member 16 has an outer end portion in the vehicle width direction bent downward, and the wheel chock member 20 is prevented from slipping on the flat surface of the retaining member 16 which is the upper surface in a state where the wheel chock member 20 is prevented from coming off at the accommodation position. The processing is uneven. For example, the retaining member 16 is made of an aluminum striped plate or a striped steel plate.

As shown in FIGS. 1A and 1B, a hooking screw 17 is fixed to the side surface of the accommodating portion 12. A rubber fixing screw 18 is provided on the bent portion 16b bent below the retaining member 16, and the lower end of the retaining rubber 19 fixed by the rubber fixing screw 18 is a lower hooking screw. By being hung on the 17, the wheel chock member 16 is prevented from unintentionally rotating upward due to vibration such as during traveling, and the wheel chock member 20 does not come out.

In the present embodiment, the wheel chock member 20 is not unintentionally pulled out by covering the upper part of the wheel chock member 20 with the wheel chock member 16 in a state of being housed in the wheel chock holder 10. Further, the wheel chock member 20 can be taken out by rotating the wheel chock member 16 and retracting it from above the wheel chock member 20.

In addition, since the flat surface that is the upper surface at the accommodation position of the retaining member 16 is anti-slip processed, the retaining member 16 can be used as a step for cleaning the packing box 5, checking the contents, hanging the sheet, and performing maintenance work. Can be used.

Further, in the present embodiment, the rudder 6 is attached to the subframe 4 in the vicinity of the wheel chock holder 10, but this rudder 6 has restrictions such as a vehicle width limitation on the dump truck 1, and a wide space for footing is wide. Often not. However, by using the retaining member 16 as a step, for example, by placing one foot on the retaining member 16 and the other foot on step 6a of the ladder 6, the packing box 5 can be cleaned more safely. You can hang a seat, perform maintenance work, etc. Further, since the retaining member 16 is also used as the step, a support structure or the like only for providing the step becomes unnecessary.

Therefore, according to the dump truck 1 according to the present embodiment, the wheel chock member 20 can be easily taken out and can be accommodated so as not to be unintentionally pulled out.

(Embodiment 2)
3A to 3C show the wheel chock holder 110 according to the second embodiment of the present invention, and are different from the first embodiment in that the structure of the chock member 116 is particularly different. In each of the following embodiments, the same parts as those in FIGS. 1A and 2 are designated by the same reference numerals, and detailed description thereof will be omitted.

That is, in the holder frame 111 of the wheel chock holder 110 of the present embodiment, a horizontal member 111a similar to the horizontal member 11a of the first embodiment is fixed to the subframe 4 by welding or the like, and the above-mentioned embodiment is performed on the horizontal member 111a. A vertical member 111b similar to the vertical member 11b of the first embodiment is welded. A strip-shaped accommodating portion 112 bent so as to accommodate the wheel chock member 20 is welded to the vertical member 111b. A pair of support members 113 are welded to the back surface side of the vertical member 111b at intervals, and a retaining member 116 is rotatably supported on the support member 113 around a rotation shaft 115. There is. As shown by the alternate long and short dash line in FIG. 3A, the retaining member 116 is configured to press the horizontally extending grip portion 20a of the wheel chock member 20 and hold it in the accommodation position. The grip portion 20a of the wheel chock member 20 is provided for lifting the wheel chock member 20 and hanging a string connecting the wheel chock members 20 to each other, and is easy to put in and take out when the wheel chock member 20 is housed in the wheel chock holder 110. It is positioned on the upper side. The retaining member 116 has, for example, a pair of front and rear plate members 116a whose lower end is rotatably supported by a rotation shaft 115, whose upper end side is bent vertically toward the grip portion 20a, and then bent upward. It has a pair of upper and lower connecting portions 116b for connecting the pair of plate members 116a. An upper spring support hole 116c is formed at the lower end of the plate member 116a.

On the other hand, a spring support portion 117 is formed in the lower center of the vertical member 11b with a predetermined distance below the pair of support members 113. A lower spring support hole 117a is formed in the spring support portion 117, and the upper end of the tension coil spring 119 as a urging member whose lower end is locked to the lower spring support hole 117a is the upper spring support hole. It is locked to 116c. The tension coil spring 119 is always urged in a direction in which the retaining member 116 is held in a state of covering the wheel chock member 20.

As described above, in the present embodiment, the grip portion 20a, which serves as the handle of the wheel chock member 20 or the portion for hanging the string, is positioned above, and the grip portion 20a is moved upward by the retaining member 116. As a result, the entire wheel chock member 20 can be easily and effectively held.

Further, when the wheel chock member 20 is housed in the wheel chock holder 10 with the retaining member 116 lifted and then released, the wheel chock member 20 is surely held at the housed position. Since the retaining member 116 does not erroneously rotate even during traveling due to the urging force of the tension coil spring 119, the wheel chock member 20 does not unintentionally come out.

Further, in the present embodiment, when viewed from the side of the dump truck 1, the tension coil spring 119, the rotation shaft 115, the retaining member 116 and the like are arranged inside the holder frame 111 instead of outside, thereby preventing the retaining member. The 116 can be installed in a narrow space with a limited front-rear width. Further, such a configuration enables a compact configuration as shown in the following modification example.

-Modification example-
4A and 4B show the wheel chock holder 210 according to the modified example of the second embodiment of the present invention, and are different from the second embodiment in that the shape of the holder frame 211 is particularly different.

That is, in this modification, the wheel chock holder 210 is configured to accommodate the wheel chock members 20 side by side.

Specifically, in the holder frame 211 of the present embodiment, a horizontal member 211a similar to the horizontal member 111a of the second embodiment is fixed to the subframe 4 by welding or the like, and the horizontal member 211a is fixed to the horizontal member 211a of the second embodiment. A vertical member 211b having a length higher than that of the vertical member 111b is welded. For example, the horizontal member 211a is reinforced on both front and rear sides by a trapezoidal flat plate-shaped first reinforcing member 211c, and the horizontal member 211a and the vertical member 211b are diagonally connected by the second reinforcing member 211d to be reinforced.

The accommodating portion 212 of this modification is the same as that of the second embodiment and is welded to the vertical member 211b at a predetermined interval in the vertical direction.

The retaining member 116 of this modification is composed of the same retaining member 116 as in the second embodiment, and is urged to rotate in a direction in which the upper wheel stopper 20 is pressed from above so as not to come out by the tension coil spring 119. Has been done.

The pair of upper and lower wheel chock members 20 have, for example, their grip portions 20a connected by a string member 221 and are accommodated side by side in the upper and lower accommodating portions 212. The lower wheel chock member 20 does not come out as long as the upper wheel chock member 20 is present because the upper wheel chock member 20 interferes with the lower wheel chock member 20.

In this modification, the pair of wheel chock members 20 can be reliably accommodated even in a narrow space having a limited front-rear width.
