Truck body of horizontal-moving-type rollover self-unloading truck

Abstract

The invention provides a truck body of a horizontal-moving-type rollover self-unloading truck. The truck body comprises a compartment. The compartment is fixed to a truck frame through two return safety pins located on one side of the compartment and a son-mother safety lock on the other side of the compartment; a sliding groove is formed in a middle crossbeam of the truck frame, and a plurality of transverse rolling shafts are embedded in a bottom plate of the sliding groove; the compartment slides leftwards and rightwards along the sliding groove, and a moving crossbeam is arranged in the sliding groove; and the tail end of the moving crossbeam is fixed to the bottom of the compartment, the front end of the moving crossbeam is connected with hoisting oil cylinders through pin shafts, andthe upper ends of the hoisting oil cylinders penetrate through the bottom of the compartment to be fixed to the upper portion of one compartment wall of the compartment. The truck body has the beneficial effects that a safety hook at the front end of the moving crossbeam can limit the compartment and can further serve as a final force-bearing point at the time of rollover of the compartment, andaccordingly a large quantity of limiting and fixing structures are omitted; and the truck body is fixed quite easily and firmly through the return safety locks and the son-mother safety lock, so thatunloading is completed in a cab in a remotely-controlled mode.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a body of a translational rollover dump truck. Background technique [0002] At present, most of the trucks are backward tipping type. Such cars have several disadvantages. One is that the dumped goods are piled up and it is not easy to arrange them. If the truck is loaded with very heavy goods, such as stones, sand, soil, etc., it is not conducive to unloading, and it will also cause damage to the carriage. [0003] Of course, there are very few trucks that use rollover to unload goods, but when this type of truck is pushed sideways, it often uses a relatively large oil cylinder, and the friction between the carriage and the frame is too large, so that it can only increase the thrust of the hydraulic cylinder. It not only takes up the space in the compartment, but also increases the burden on the truck. Contents of the invention [0004] In order to solve the problems...

Problems solved by technology

[0002] At present, most of the trucks are backward tipping type. Such cars have several disadvantages. One is that the dumped goods are piled up and it is not easy to arrange them. If the truck is loaded with very heavy goods, such as stones, sand, mud, etc., it is not conducive to unloading, and it will also cause damage to the carriage.

[0003] Of course, there are very few trucks that use rollover to unload goods, but when this type of truck is pushed sideways, it often uses a relatively large oil cylinder, and the friction between the carriage and the frame is too large, so that it can only increase the thrust of the hydraulic cylinder. It not only occupies the space in the compartment, but also increases the burden on the truck
