Novel wing opening type self-dumping semitrailer and self-dumping method thereof

Abstract

The invention discloses a novel wing opening type self-dumping semitrailer and a self-dumping method thereof, belongs to the technical field of semitrailers, solves the technical problems of safe operation, high efficiency and environmental protection of the self-dumping semitrailer in an operation site, and according to the technical scheme, the self-dumping semitrailer comprises a frame, a carriage body, a self-dumping mechanism, a side door locking mechanism and a lifting hydraulic system; the carriage body is welded to the frame; the self-dumping mechanism is arranged in the carriage body and hinged to the carriage body, one end of the lifting hydraulic system is hinged to the frame, the other end of the lifting hydraulic system is hinged to the self-dumping mechanism, and the lifting hydraulic system drives the side door of the carriage body to turn over towards the outer side of the carriage body through the self-dumping mechanism; the side door locking mechanism is arranged on the carriage body, and the side door locking mechanism and the lifting hydraulic system synchronously control opening or closing of the side door. The semitrailer can adapt to complex operation sites, goods are unloaded when the carriage body is in a horizontal state, the anti-rollover capacity of the semitrailer is improved, operation is convenient, wheels are not buried by the goods, and the unloading efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of semi-trailers, and in particular relates to a novel wing-opening self-unloading semi-trailer and a self-unloading method thereof. Background technique [0002] Semi-trailers can be divided into ordinary semi-trailers, warehouse-type semi-trailers, container-type semi-trailers, van-type semi-trailers, tank-type semi-trailers, special semi-trailers, dump semi-trailers, low-bed semi-trailers, etc. according to their structural characteristics. Dump truck, also known as dump truck, refers to a special vehicle that is equipped with a lifting mechanism on the frame to automatically tilt the cargo. It has a high degree of automation and convenient unloading, and has played a huge role in the transportation of coal, ore, earthwork and other materials. . In recent years, under the background of accelerated infrastructure investment, production has increased significantly, with a growth rate of more than 200%. ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to its high center of gravity and uneven force when unloading, the rear-turning dump truck is prone to rollover accidents, which also indirectly limits the length of the car body;

[0005] 2. When the rollover semi-trailer is unloading, the center of gravity of the cargo and the center of gravity of the vehicle are skewed, and the semi-trailer is easy to roll over on a soft or sloping work site, and the wheels of the semi-trailer are easily sunken in the dumped cargo to prevent the vehicle from starting. ;

[0006] 3. When the floor-turning dump truck is running and unloading, the cargo is easy to leak from the middle, and the flap is prone to jamming. There is also the problem that the wheels of the semi-trailer are easily sunken in the dumped cargo and hinder the vehicle from starting.
