Motor active speed-reduction buffer system for measurement and control of forklift stroke

Abstract

The invention provides a motor active speed-reduction buffer system for measurement and control of a forklift stroke and aims to solve the problem of forklift shaking and vibration easily caused by severe impact when a forklift lifts or descends goods to the tail end of the stroke. The motor active speed-reduction buffer system comprises a pump motor, a vehicle controller, an ascending switch, a descending switch, a 24V power supply, a 80V power supply, a signal processing unit, an ascending buffer enabling switch and a descending buffer enabling switch, wherein the 24V power supply is connected with the signal processing unit through the ascending buffer enabling switch; the 24V power supply is connected with the signal processing unit through the descending buffer enabling switch; and the signal processing unit is connected with the vehicle controller and the 80V power supply respectively. The motor active speed-reduction buffer system has the advantages that the impact force during the goods ascending or descending process is reduced effectively, damage to forklifts is reduced, and the problems that bounce can occur easily and equipment can be worn and even fail easily when a buffer is used are solved; and the structure is simple, installation and debugging are convenient, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of forklift control, and in particular relates to a motor active deceleration buffer system when cargo is lifted and lowered to the end of a stroke. Background technique [0002] During the working process of the forklift, the lifting and lowering of the goods are its basic actions. When the cargo rises to the top, due to the stroke limitation of the lifting cylinder, it will stop by the collision when the piston of the cylinder hits the guide sleeve. Due to the high speed of the cargo, when the cylinder piston and the guide sleeve collide, a certain impact force and noise will be generated, resulting in vibration of the vehicle body and shaking of the cargo at a high altitude. Similarly, when the cargo falls to the bottom, it is stopped by the collision of the cylinder piston and the bottom of the cylinder, which also produces a large impact force, causing the vehicle to shake and vibrate. [0003] For th...

Problems solved by technology

[0004] However, using a buffer to reduce the impact force has the following disadvantages: 1) The energy converted into heat is dissipated and cannot be reused; 2) During the buffering process, it is easy to form a rebound; 3) The structure is complex and inconvenient to install
