Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle testing, in particular to a counterweight box for performance test of a hook arm garbage truck. BACKGROUND

[0002] The hook arm garbage truck is also called a detachable garbage truck, which is generally composed of a hook arm truck and a garbage box. During the working process of the hook arm garbage truck, the hook arm truck needs to hoist the garbage box filled with garbage from the ground to the truck body. Since the garbage box filled with garbage is heavy, the hook arm truck has high requirements for rigidity and strength. Therefore, after the production of the hook arm garbage truck is completed, the performance of the hook arm truck needs to be tested.

[0003] The method of the hook arm truck performance test is generally as follows: a special counterweight box is used to simulate the garbage box filled with garbage. The counterweight box is loaded with weights to increase its counterweight. A fixing structure for fixing the weights is arranged in the counterweight box. The counterweight box is used for testing with the hook arm truck. For the same type of hook arm truck, the counterweight box can be repeatedly used without replacing the weights, which is very convenient to use.

[0004] However, for different types of hook arm garbage trucks, since their carrying capacities are different, the weight requirements of the counterweight box are different. The counterweight box needs to load weights of different weights, and the sizes of the weights of different weights are different. The fixing structure for fixing the weights in one counterweight box can generally only fix weights of a specific size, which leads to the fact that the counterweight box can only be applied to one type of hook arm garbage truck, and the universality is poor. SUMMARY

[0005] The purpose of the present application is to provide a counterweight box for performance test of a hook arm garbage truck with good universality.

[0006] To achieve the above purpose, the counterweight box for performance test of a hook arm garbage truck provided by the present application adopts the following technical scheme:

[0007] The counterweight box for performance test of a hook arm garbage truck comprises:

[0008] The box body has a loading space for loading counterweight blocks. The box body is provided with at least a rolling body at the bottom of the rear end to facilitate the movement of the box body when the front end of the box body is lifted.

[0009] The hanging ring is arranged on the outer side of the front wall of the box body and is used for hooking the hook of the hook arm truck.

[0010] A plurality of position-adjustable limiting blocks are installed on the bottom of the box body for limiting the weight block in the front-back and left-right directions, a T-shaped slot extending in the front-back direction and having a narrow upper part and a wide lower part is arranged on the bottom of the box body or a bottom fixing body arranged on the bottom, the T-shaped slot is arranged in a plurality of and is arranged in the left-right direction to achieve the position adjustment of the limiting block in the left-right direction, a locking bolt for fixing the limiting block is arranged in the T-shaped slot, the limiting block is fixed on the T-shaped slot through the locking bolt and a matching locking nut, and the stepless adjustment of the position of the limiting block in the front-back direction is achieved through the cooperation of the T-shaped slot, the locking bolt and the matching locking nut.

[0011] The weight box for performance test of the hook arm garbage truck has the following advantages: a plurality of position-adjustable limiting blocks are installed on the bottom of the box body, the plurality of limiting blocks can limit the weight block in the front-back and left-right directions, the position of the limiting block is adjustable, the size of the weight block can be changed at will to adjust the total weight of the weight box, which is very convenient, and the weight box can be applied to different models of hook arm garbage trucks and has good versatility.

[0012] Further, the weight box for performance test of the hook arm garbage truck further comprises a position-adjustable protection piece installed on the bottom or the left and right side walls of the box body, the protection piece is fixed to the rear side of the weight block after the weight block is loaded, so as to prevent the weight block from tilting backward when the front end of the box body is lifted. For some high weight blocks, if the height of the limiting block is small, the weight block is likely to tilt backward when the front end of the box body is lifted, which not only affects the test, but also has certain safety hazards. The protection piece can well avoid the above situation, and the height of the limiting block can be small, thereby reducing the material consumption of the limiting block.

[0013] Further, the protection piece is a protection support extending in the left-right direction, and the two ends of the protection support are connected with the left and right side walls of the box body. The two ends of the protection support are connected with the left and right side walls, so that the protection support is stable and is not easy to deform or have other abnormal conditions.

[0014] Further, a T-shaped slot extending in the front-back direction is arranged on the left and right side walls of the box body or a side wall fixing body arranged on the left and right side walls, the T-shaped slot is arranged in a plurality of and is arranged in the up-down direction, the T-shaped slot has an inward opening and a locking bolt for fixing the protection support is arranged in the T-shaped slot, and the protection support is fixed on the T-shaped slot through the locking bolt and a matching locking nut. The protection support is fixed through the cooperation of the T-shaped slot, the locking bolt and the matching locking nut, so that the stepless adjustment of the position of the protection support in the front-back direction can be achieved, and the versatility is high. In addition, the plurality of T-shaped slots are arranged in the up-down direction, so that the position of the protection support in the up-down direction can be adjusted, and the versatility of the weight box is further improved.

[0015] Further, the T-shaped grooves are arranged on the side wall fixing bodies, and the T-shaped grooves are one-to-one corresponding to the side wall fixing bodies. In this way, the T-shaped grooves on the side wall fixing bodies are facilitated to be arranged.

[0016] Further, the T-shaped grooves are arranged on the bottom fixing bodies, and the T-shaped grooves are one-to-one corresponding to the bottom fixing bodies. In this way, the T-shaped grooves on the bottom fixing bodies are facilitated to be arranged.

[0017] Further, the limiting blocks are L-shaped limiting blocks having longitudinal sections extending in the front-rear direction and transverse sections extending in the left-right direction. In the case that the number of limiting blocks is the same, the stability of the counterweight block is higher when the L-shaped limiting blocks are used.

[0018] Further, the counterweight box for performance test of the hook arm garbage truck is further provided with a cushion block, which is arranged in the spacing space between the limiting block and the counterweight block during use, so as to prevent the counterweight block from moving in the front-rear and left-right directions during use. In this way, the stability of the counterweight block during use after loading is increased. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0030] The specific embodiments of the present application will be further described below in combination with the drawings.

[0031] The embodiment of the counterweight box for performance test of the hook arm garbage truck provided by the present application:

[0032] As shown in Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the counterweight box comprises a box body, the box body has a loading space for loading the counterweight blocks 13 in the box body, and the box body comprises a front wall 1, a rear wall 16, a bottom plate 3 and two left and right side walls 2; a hanging ring 4 is fixed on the outer side of the front wall 1 of the box body, the hanging ring 4 is used for being hooked by the hook on the hook arm truck, so as to drive the counterweight box to perform the test; two rollers 15 are arranged at the bottom rear end of the box body along the left and right directions, the two rollers 15 are used for supporting the forward movement of the counterweight box when the front end of the counterweight box is lifted by the hook arm truck; and the rollers 15 constitute the rolling body arranged at the bottom rear end of the box body.

[0033] As shown in Figure 1 , Figure 4 and Figure 5 , a plurality of guide rails 5 are arranged on the bottom plate 3 of the box body along the left and right directions, the guide rails 5 are arranged one by one along the left and right directions (the guide rails 5 are arranged in the T-shaped groove 8) Figure 1Only a portion of the guide rails 5 is shown. Each guide rail 5 has a T-shaped groove 8 that is narrower at the top and wider at the bottom, extending in the front-to-back direction. The T-shaped grooves 8 on the base plate 3 are spaced apart in the left-to-right direction. Multiple locking bolts 11 are arranged in the T-shaped grooves 8. The bolt heads of the locking bolts 11 extend into the wider groove of the T-shaped groove 8 and engage with the step in the T-shaped groove 8 to prevent vertical detachment. Each locking bolt 11 is equipped with a matching locking nut 12. Limiting blocks 6 are fixed on the guide rails 5 by the locking bolts 11 and locking nuts 12. The limiting blocks 6 have a transverse section extending in the left-to-right direction and a section extending in the front-to-back direction. The longitudinal section has an L-shaped limiting block 6 with three fixing holes corresponding to the T-shaped groove 8. Two fixing holes are located on the longitudinal section and correspond to one T-shaped groove 8, and the third fixing hole is located on the transverse section and corresponds to another T-shaped groove 8. The limiting block 6 is used to limit the counterweight 13 in the front-back, left-right and right directions. In use, each counterweight 13 (the counterweight is generally square) is equipped with four limiting blocks 6. The four limiting blocks 6 are arranged at the four corners of the counterweight 13. The counterweight 13 is placed on the guide rail 5. The side of the limiting block 6 facing the counterweight 13 is used to limit the counterweight 13. The guide rail 5 on the bottom plate constitutes the bottom fixing body set at the bottom of the box.

[0034] Because the locking bolt 11 can be guided to move along the T-slot 8, the limiting block 6 can also be guided to move in the front-back direction. Furthermore, the fixing holes on the limiting block 6 can be replaced to correspond to different T-slots 8, so that the position of the limiting block 6 in the left-right direction can be adjusted. Therefore, different sizes and positions of the counterweight blocks 13 can be fixed by adjusting the different positions of the limiting block 6 on the base plate 3.

[0035] like Figure 6 As shown, because the position of the limiting block 6 in the left and right directions is adjustable by using its fixing holes to correspond to different T-slots, the limiting block 6 cannot be steplessly adjusted in the left and right directions. Often, after the counterweight 13 is placed in place, and the limiting block 6 is fixed in the T-slot 8 closest to the counterweight 13 in the left and right directions, there is still a certain gap between the longitudinal section of the counterweight 13 and the limiting block 6. Therefore, the counterweight box is equipped with a pad 14. The pad 14 can be inserted into the corresponding gap when there is a gap between the longitudinal section of the limiting block 6 and the counterweight 13, thereby limiting the counterweight 13 in the left and right directions. Since the position of the limiting block 6 in the front and back directions can be steplessly adjusted, the limiting block 6 can be directly adjusted so that its lateral section is close to the side of the counterweight 13 and fits tightly against the corresponding side of the counterweight 13, without the need to add a pad 14. Of course, it is not limited to adding a pad 14 between the lateral section of the limiting block 6 and the counterweight 13.
