Automatic carriage body scrolling-type closed system

Abstract

The invention relates to an automatic carriage body scrolling-type closed system. The front end of a carriage body is provided with an erection mechanism, wherein the erection mechanism is provided with a motor or a hydraulic motor; a rotating shaft is also arranged in front of the carriage body, an awning cloth is wound on the rotating shaft, the other end of the awning extends to the tail end of the carriage body and is provided with a tail end shaft; two side surfaces of a dumper carriage body are respectively provided with a drawing bar, an end A of the drawing bar is hinged with the tail end shaft, and an end B of the drawing bar is hinged onto the two side surfaces of the carriage body by virtue of a rotating supporting point; and two ends of the rotating shaft are provided with a transmission gear, and a drive shaft of the motor or the hydraulic motor is connected with the transmission gears at two ends of the rotating shaft by virtue of a chain. When in use, the drawing bars rise up and drive the awning cloth to move forwards until the awning is completely scrolled, so that conditions such as collision, deformation and the like can be avoided in the process of unfolding and folding the awning cloth, and the phenomenon such as clamping stagnation is also avoided when in movement.

Description

technical field [0001] The patent of the invention is a box-rolling-type automatic airtight system. Specifically, a motor or a hydraulic motor is used to drive the chain to shrink the tarpaulin, and the tension of the tension spring is utilized and overcome to realize the shrinkage of the tarpaulin. Background technique [0002] As the country pays more and more attention to urban muck control and smog control, most domestic muck trucks and van transport vehicles use rollers to move in a straight line on steel wires (or chains) on guide rails, relying too much on the box body. If there is a lot of body deformation, there will be stagnation, damage, and the phenomenon that the tarpaulin cannot be retracted normally. Therefore, an automatic airtight system that does not rely on the movement of the box body is becoming more and more important. [0003] Such as figure 1 Shown: [0004] The device is prone to bumping and deformation during transportation and loading, and it is ...

AI Technical Summary

Problems solved by technology

[0004] The device is prone to bumping and deformation during transportation and loading, and it is easy to accumulate muck, stone chips, etc., resulting in jamming during movement.

In addition, the front corner, the track wire rope, the tail fixing device, and the tail pulley are all welded on the car body, which is easy to deform, weld errors, etc.

[0005] When using chains or wire ropes for transmission, it is also prone to bumping and deformation during transportation and loading, and it is easy to accumulate muck and stone chips, which will cause jamming during movement, etc.
