[0002] Dump trucks are vehicles that unload goods by themselves through hydraulic or mechanical lifting, also known as tipping trucks. Generally speaking, dump trucks are special vehicles that have a hydraulic lifting mechanism installed on the chassis of current dump trucks. The hydraulic lifting mechanism is driven by the engine of the vehicle, the vehicle body is tilted at a certain angle to unload goods, and the vehicle body is reset by its own weight. The appearance of dump trucks is a handling device developed using high technology as the work of handling is no longer manpower-intensive.

[0003] The existing patent (Announcement No.: CN207607398U) discloses a support frame for a truck dump truck, which reduces the load on the parts of the cargo compartment during dump truck operation and reduces the maintenance cost of the dump truck. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:

[0004] When a truck is unloading, all of its gravity moves toward the rear. When a large amount of cargo is concentrated at the rear of a small truck, it is easy to cause the front of the truck to tilt up. Therefore, a jack will be installed at the rear, but the jack cannot adapt to the uneven terrain. Some trucks will have a lifting bracket, but the lifting bracket will lower the truck chassis, which is easy to bump during transportation. Utility Model Content

[0011] Through the above technical solution, it is convenient to drive the rotating rod to reset through the torsion spring, thereby facilitating the automatic reset of the protective block.

[0012] Optionally, in the above-mentioned support frame for trucks, the cylinder forms a rotating structure with the truck compartment through a connecting rod, the cylinder and the shift block are installed in an integrated manner, and the cylinder is symmetrically distributed on both sides of the center of the truck compartment.

[0013] Through the above technical solution, it is convenient to cooperate with the cylinder and the connecting rod so that the cylinder can rotate, which is convenient for the subsequent support work of the truck.

[0014] Optionally, in the above-mentioned truck support frame, the connection between the piston rod and the cylinder is a piston connection, the connection between the piston rod and the linkage block is a hot-melt connection, and shock-absorbing springs are evenly and equidistantly distributed on the right side of the linkage block.

[0019] Through the above technical solution, it is convenient to utilize the toggle block and the card slot to perform secondary limit fixation on the cylinder to ensure the stability of the cylinder.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0030] The inner side of the cylinder 4 is also connected to a piston rod 5, and the other side of the piston rod 5 is connected to a linkage block 7. The linkage block 7 is driven by the piston rod 5 to move, so as to carry out subsequent supporting work. The other side of the linkage block 7 is also connected to a shock-absorbing spring 8, and the other side of the shock-absorbing spring 8 is connected to a base plate 9. Multiple base plates 9 are used to fit the ground to ensure the supporting efficiency. An adsorption magnet 10 is provided on the other side of the base plate 9.

[0031] See the attached drawings in the specification Figure 1-4 Protection blocks 3 are symmetrically distributed on both sides of the truck compartment 2. The protection blocks 3 form a rotating structure with the truck compartment 2 through a rotating rod 6. Torsion springs are connected to both sides of the rotating rod 6. The rotating rod 6 is driven to reset by the torsion springs, thereby facilitating automatic reset of the protection blocks 3.

[0032] See the attached drawings in the specification Figure 1-4 The cylinder 4 forms a rotating structure with the truck compartment 2 through the connecting rod 12. The cylinder 4 and the toggle block 11 are installed in an integrated manner. The cylinder 4 is symmetrically distributed on both sides of the center of the truck compartment 2. The cylinder 4 cooperates with the connecting rod 12 to allow the cylinder to rotate, which is convenient for subsequent support work on the truck.

[0033] See the attached drawings in the specification Figure 1-4 The connection between the piston rod 5 and the cylinder 4 is a piston connection, and the connection between the piston rod 5 and the linkage block 7 is a hot-melt connection. Shock-absorbing springs 8 are evenly and equidistantly distributed on the right side of the linkage block 7. Through the cooperation between the piston rod 5 and the linkage block 7, the linkage block 7 can be raised and lowered, which is convenient for auxiliary support of the truck compartment 2.

[0034] See the attached drawings in the specification Figure 1-4 The linkage block 7 forms a spring shock-absorbing structure with the bottom plate 9 through the shock-absorbing spring 8. The number of the positions of the bottom plate 9 is consistent with the number of the positions of the adsorption magnets 10. The adsorption magnets 10 are integrated with the truck compartment 2. The bottom plate 9 is fixed by the adsorption magnets 10 to prevent the bottom plate 9 from falling off and onto the ground during truck transportation.

[0035] See the attached drawings in the specification Figure 1-4 The connection between the toggle block 11 and the toggle slot 13 is a sliding connection. Semi-annular grooves are provided on both sides of the toggle slot 13. The toggle block 11 and the grooves are engaged with each other. The toggle block 11 cooperates with the grooves to perform secondary limit fixation on the cylinder 4 to ensure the stability of the cylinder 4.

[0036] Working principle: When in use, first, during transportation, the cylinder 4 is in a parallel state with the truck base 1. At this time, the adsorption magnet 10 is attached to the bottom plate 9 to fix the bottom plate 9 to prevent the bottom plate 9 from falling off. The toggle block 11 on the outside of the cylinder 4 is engaged in the slot above the toggle slot 13 to ensure that the cylinder 4 will not move downward;

[0037] When unloading, manually grab the toggle block 11 and move it downward along the toggle slot 13, so that the toggle block 11 is separated from the upper slot and enters the lower slot, and the rear cylinder 4 moves with the movement of the toggle block 11. When the cylinder 4 moves, it abuts against the protective block 3 and pushes the protective block 3 to move downward. When the cylinder 4 is in a vertical state, turn on the switch of the cylinder 4, so that the piston rod 5 drives the linkage block 7 to move downward, so that the bottom plate 9 moves downward until it is in contact with the ground. At the same time, because the shock-absorbing springs 8 above each bottom plate 9 are independently connected, the bottom plate 9 will also be extended and retracted when the terrain becomes uneven to ensure fixation, and then it is lifted up by the driving mechanism under the truck compartment 2 for unloading, and it can be reset after unloading.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
