[0002] The current rear tipping dump trucks do not have a safety support device, which can be adapted to medium and small rear tipping dump trucks with short cargo boxes, but for dump trucks with longer cargo boxes and larger loading capacity, especially For the rear-turning semi-trailer dump truck, its stability and safety performance have not been truly guaranteed. At present, there is only a small two-folding cage, which is installed in the lower part of the cargo box, but its function can only be It is to play a lateral guarantee for the cargo box body. If the car box body suddenly and rapidly drops due to a failure of the lifting cylinder or the hydraulic system of the lifting cylinder, it will not be able to provide protection at all.

The invention provides a back-tipping dumper with a safety support. According to the invention, a set of mechanism is mounted between the cargo tank body of the dumper and the auxiliary frame of a dumper chassis; the mechanism consists of a rigid stay bar frame, ratchet plates, ratchet bars and a damping oil cylinder. When the cargo tank body rises under the action of a front lifting oil cylinder, the stay bar frame, the ratchet plates and ratchet bars effectively perform a safeguard function and improve the stability; when the cargo tank body falls, the damping oil cylinder system ensures the falling stability and falling safety. The safety support mechanism is most applicable to a back-tipping dumper with a long cargo tank body and large load capacity.
Description
technical field [0001] A rear dump truck with a safety bracket, which is suitable for being installed on various freight car chassis, semi-trailer chassis or full trailer chassis to form a rear dump truck, semi-trailer dump truck or full trailer equipped with a safety bracket. Hang the dump truck. Background technique [0002] The current rear tipping dump trucks do not have a safety support device, which can be adapted to medium and small rear tipping dump trucks with short cargo boxes, but for dump trucks with longer cargo boxes and larger loading capacity, especially For the rear-turning semi-trailer dump truck, its stability and safety performance have not been truly guaranteed. At present, there is only a small two-folding cage, which is installed in the lower part of the cargo box, but its function can only be It is to play a lateral guarantee to the cargo box body, as the car box body suddenly and rapidly descends because of the failure of the lift cylinder or the hy...
