Anti-hit and anti-deformation tail plate of cargo compartment of dump truck and dump truck provided with tail plate

Abstract

The invention provides an anti-hit and anti-deformation tail plate of a cargo compartment of a dump truck and the dump truck provided with the tail plate. The dump truck comprises a truck body and the cargo compartment which comprises a front plate (1), left and right side plates (2), a base plate (3), the tail plate (4), a tail plate large locking hook, a manual hook device (6) and a rotary hook base (7). A series of measures of reinforcement, leaking and falling prevention, material accumulation prevention and safe locking are taken for the tail plate. By adoption of the anti-hit and anti-deformation tail plate of the cargo compartment of the dump truck and the dump truck provided with the tail plate, compared with the prior art, the cargo compartment has the advantages of being resistant to hit, expansion, impact, squeezing and deformation, free of material accumulation and long in service life and has the characteristics that boosting by other machines is facilitated when the dump truck is trapped or resisted and small-particle-size materials in the cargo compartment can be prevented from leaking and falling during transportation.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to an anti-smashing and anti-deformation dump truck container tail plate and a dump truck with the tail plate. Background technique [0002] Dump trucks are the most commonly used soil, sand and gravel transportation tools in engineering construction and mine construction. The use environment is relatively harsh, and most of them are short-distance transportation. Therefore, as a key component for frequent opening and closing of the dump truck, the tail plate of the dump truck has a direct impact on the performance and life of the vehicle, and is also an important guarantee for the normal operation of the dump truck. The tail plate of the dump truck in the prior art has the following problems: (1) When loading goods, large pieces of material hit the tail plate of the container, and the inner side of the plate of the tail plate is damaged by potholes due to the impact ...

AI Technical Summary

Problems solved by technology

The tail plate of the dump truck in the prior art has the following problems: (1) When loading goods, large pieces of material hit the tail plate of the container, and the inner side of the tail plate is damaged by potholes due to the impact of the material

(2) When the dump truck is fully loaded, the tail plate is subject to a large extrusion force from the goods in the container, and the tail plate is easy to deform backwards and expand outwards

(3) When unloading, the front part of the cargo box is lifted, and the cargo quickly rushes to the tail plate, especially when the cargo is a large rock, the huge impact force causes the tail plate to be uneven, and in serious cases, the horizontal and vertical reinforcement ribs on the rear side are burst or even damaged

(4) During the lifting and unloading process of the front of the container, the tail of the dump truck is asymptotically approaching the ground, and the lower part of the tailgate will be blocked by the unloaded cargo and damaged due to extrusion

(5) If the dump truck falls into a mud pit, it needs to be pushed forward by machinery such as an excavator or a forklift, and the tail plate of the cargo box is easily deformed and damaged under such external force

(6) The upper two sides of the tailgate are hinged with the hook seats on the left and right sides of the container, and the lower two sides are connected with the manual hooks on both sides of the bottom plate of the container. The tailgate is easily damaged at these four stress concentration points; (7 ) When loading goods, materials are easy to accumulate on the horizontal and vertical ribs on the rear side of the tailgate. When the vehicle is running, the accumulated materials will fall and fly, causing pollution to the road surface and the environment; Strict, if the cargo is in the form of granules or powder, it is easy to leak from the joint between the tailgate and the side floor of the cargo box, causing pollution to the road surface and the environment, and threatening the safety of pedestrians
