Speed-limiting safety system of high-position stacking door frame

Abstract

The invention discloses a speed-limiting safety system of a high-position stacking door frame. The speed-limiting safety system comprises a hoisting control system, a drive control system, a DC converter and a proximity sensor; the hoisting control system comprises a hoisting motor, a hoisting controller, a hoisting switch, an inclining switch, a forward-moving switch, a hoisting speed-limiting mode switch and a transferring limiting mode switch, wherein the hoisting switch, the inclining switch, the forward-moving switch, the hoisting speed-limiting mode switch and the transferring limiting mode switch are electrically connected to pins of the controller; and the drive control system comprises a drive motor, a drive controller, an advancing switch, a retreating switch, a driving pedal switch, an accelerator and a driving crawling mode switch, wherein the advancing switch, the retreating switch, the driving pedal switch, the accelerator and the driving crawling mode switch are electrically connected to pins of the drive controller. According to the speed-limiting safety system, dynamic impact on the door frame in the process of stacking operation (ascending and descending, front-back moving of the door frame and front-back driving of a forklift) can be effectively reduced, the high-position loading capacity of the door frame can be improved, and the probability that cargos fall because of misoperation (fast driving and fast descending) in the high-position stacking process can be lowered.

Description

Technical field: [0001] The invention relates to the field of electric forklifts, and mainly relates to a speed-limiting safety system for high-position stacking masts. Background technique: [0002] With the rapid development of the modern warehousing and logistics industry, and due to the rapid growth of land costs, newly developed logistics parks, warehouses are all developing in the direction of high-density storage and ultra-high storage. In this market environment, storage-type electric reach trucks must not only meet the requirements of exquisite body structure and excellent stacking channel capacity, but also must have excellent high-level or ultra-high-level load stacking capacity of more than 10 meters. In response to this change in the market, it is urgent to quickly launch corresponding safe, reliable and excellent performance storage and logistics equipment in the industry. [0003] As an important type of warehousing forklift, the electric stand-and-drive fork...

AI Technical Summary

Problems solved by technology

[0005] During ultra-high stacking, there are certain potential safety hazards due to factors such as poor vision of the driver, large sway of the door frame of the body, large inertial force impact such as lifting and lowering of the cargo, and forward and backward movement.
