Horizontally pushing type dumper

Abstract

The invention provides a horizontally pushing type dumper, which can move loaded cargoes backward as a whole to realize unloading. The horizontally pushing type dumper comprises a flat bottom type carriage; the flat bottom type carriage comprises a front breast board, a left side breast board, a right side breast board, a bottom board, front stand columns and rear stand columns; the carriage is internally provided with a push board which is in parallel to the front breast board; the left side breast board, the right side breast board and the bottom board are provided with longitudinal slideways or slide rails; correspondingly, the push board is provided with slide blocks or slide grooves; the left side breast board, the right side breast board and the bottom board form a movable pair with the push board; the push board can move backward and forward along the carriage under the drive of a push board driving device; when the cargoes are unloaded, the push board moves backward; and after the cargoes are unloaded, the push board moves forward to reset. According to the invention, when the cargoes are unloaded, the horizontally pushing type dumper does not need to lift the carriage and can unload the cargoes in the carriage completely only by moving the push board backward; unloading through tipping the carriage is changed to the unloading through horizontal movement, thereby promoting the cargo capacity and the vehicle stability and meanwhile reducing the probabilities that a vehicle frame suffers permanent deformation, and snap of welded joints happens in the carriage and an auxiliary frame.

Description

technical field [0001] The invention relates to a dump truck, in particular to a flat-push dump truck. Background technique [0002] Dump truck (dump truck) refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting. In the prior art, the compartment of a dump truck is divided into two types: backward tipping and sideways tipping. Backward tipping is more common. A few tip over in both directions. From a structural point of view, the structure of the engine, chassis and cab of a dump truck is the same as that of a general truck. Composition of tubing etc. [0003] The working principle of the dump truck: the engine drives the hydraulic pump through the transmission and the power take-off device, and the high-pressure oil generated enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and pushes the piston rod to tip the carriage. The carriage stops at any desired inclined position. The compartment is reset ...

AI Technical Summary

Problems solved by technology

Due to the heavy curb weight, it directly leads to the reduction of the rated cargo capacity, which reduces the transportation profit

[0006]2. High vehicle center of gravity

Due to the high center of gravity of the vehicle, the stability of the vehicle will decrease when driving, especially when driving on a curve at a relatively high speed or when driving on a straight road with a full load and high speed (>80km / h) for emergency braking, if the braking forces of the left and right wheels are not equal, the Easy to cause the vehicle to overturn

[0007]3. The frame is easy to deform

When the lifting hydraulic cylinder is lifting the carriage, the frame is subject to the concentrated force with the support point of the lifting hydraulic cylinder as the action point, which may easily cause permanent deformation of the carriage and open welding of the carriage and the sub-beam of the carriage.

[0008]4. Problems during unloading

For a dump truck with a sideways tipping compartment, the weight will be concentrated on one side of the overturn pin of the compartment during unloading, which will cause early damage to the tires on this side

In addition, if the ground is uneven when unloading, and the whole vehicle is in a tilted state in the direction of side unloading, it is very easy to cause the vehicle to tip over.
