A manual forklift with self-leveling function

Abstract

The invention belongs to the technical field of reel transportation and particularly relates to a manual forklift with a self-leveling function. The forklift comprises a movable supporting plate. Thetail end of the movable supporting plate and the tail ends of supporting claws form hinged fit, and the axis of a horizontal hinge shaft of the movable supporting plate and the supporting claws is vertically positioned on the axes of discs on the supporting claws. The forklift further comprises hydraulic jacks. The bottom ends of the hydraulic jacks are fixed to the front ends of the supporting claws, and the top ends of the hydraulic jacks vertically extend upwards and are supported at the lower plate surface of the head end of the movable supporting plate from bottom to top. The forklift further comprises a hydraulic assembly for driving the two groups of hydraulic jacks positioned at the front ends of the two supporting claws to generate synchronous lifting action, wherein the hydraulicassembly comprises a hydraulic pump, and the hydraulic pump is communicated with the two groups of hydraulic jacks through a hydraulic pipeline and an oil path distribution valve. By the adoption ofthe forklift, it can be simply and quickly ensured that the supporting surface of the forklift is in a horizontal state so as to ensure the reliability and efficiency of the penetrating action of thediscs relative to a main shaft of a pay-off rack.

Description

technical field [0001] The invention belongs to the technical field of coil transportation, and in particular relates to a manual forklift with a self-leveling function. Background technique [0002] During the production process of stranded wire, a manual hydraulic pallet forklift will be used to lift the reel containing hundreds of kilograms of copper wire and put it on the main shaft of the pay-off rack. Because the wire reel is heavy and stuck between the two supporting claws of the forklift, if things go on like this, the front ends of the two supporting claws will be slightly separated, so that the center of gravity of the car body will be forward after the force is applied, and the front wheels will begin to deform and flatten, and the wear will accelerate, resulting in support Sinking phenomenon at the tip of the claw. Once the head ends of the two supporting claws of the forklift sink, it will cause the support surface of the forklift to be non-level, and then caus...

AI Technical Summary

Problems solved by technology

Because the wire reel is heavy and stuck between the two supporting claws of the forklift, if things go on like this, the front ends of the two supporting claws will be slightly separated, so that the center of gravity of the car body will be forward after the force is applied, and the front wheels will begin to deform and flatten, and the wear will accelerate, resulting in support Sinking phenomenon at the tip of the claw

Once the head ends of the two supporting claws of the above-mentioned forklift sink, it will cause the support surface of the forklift to be out of level, which in turn will cause the plate on the support surface of the forklift to be in a state of axis inclination

Obviously, the plate with inclined axis cannot smoothly penetrate the main shaft of the pay-off rack horizontally, and it will frequently collide with the main shaft of the pay-off rack or even get stuck, which will affect the production efficiency of the twisted wire at least, and cause damage due to impact. Cause the plate to fall from a height, resulting in production accidents
