Side door-opening mechanism of self-discharging vehicle and self-discharging vehicle with the mechanism

Abstract

The invention relates to a side-carriage door opening mechanism for a self-dumping truck and the self-dumping truck which comprises the same. The side-carriage door opening mechanism comprises a vehicle frame, carriage floor and two side carriage plates, wherein the lower ends of the side carriage plates can be opened or closed, and the side carriage plates are arranged on both sides of the vehicle frame; lower beams of the two side carriage plates are fixed with a plurality of snap close pieces respectively; snap close holes are formed inside various snap close pieces; locking pieces which are matched with the snap close pieces are arranged on both sides of the vehicle frame respectively; each locking piece comprises a locking rod which fixes a plurality of locking hooks on the same side, and a power element which drives the locking rod to perform reciprocating rectilinear motion; and hooking ends of various locking hooks are inserted into the matched snap close holes, so as to lock the side carriage plates, or are withdrawn from the matched snap close holes, so as to open the side carriage plates. The snap close pieces and the locking pieces of the side-carriage door opening mechanism for the self-dumping truck are easy to match, and the side carriage plates are easy to open and close, so that clamping stagnation of the locking hooks can be effectively prevented. Moreover, the side-carriage door opening mechanism for the self-dumping truck effectively prevents the lower ends of the side carriage plates from being deformed, and makes the side carriage plates abut against the vehicle frame.

Description

technical field [0001] The invention relates to a door opening mechanism of a dump vehicle, in particular to a door opening mechanism of a side compartment of a dump vehicle. Background technique [0002] The door opening mechanism of the dump truck side compartment provided by the prior art mostly adopts a rod mechanism, and the side compartment is tightly closed by adjusting the hook of the pull rod assembly. The hook of the door opening mechanism is stuck, which makes the side compartment unable to be closed and locked. Because the hook itself has no power to control, once the hook gets stuck, it is necessary to manually perform anti-deformation correction on the side box and the hook, which is labor-intensive and time-consuming. [0003] Such as figure 1 The shown is the door-opening mechanism of the dump truck side compartment provided by the prior art, which includes a seat plate 1' fixedly connected to the lower side of the side compartment, and the seat plate 1' is...

[0005] However, it can be seen from the above structure that the whole door-opening mechanism of the door-opening mechanism of the dump truck side compartment provided by the prior art is composed of rods without support. Once the lower frame of the side compartment is deformed, it is easy to produce hooks and seat plates Stuck, so that the hook and
