A self-reactive multi-purpose mechanical limit anti-lock device and method

Abstract

The invention discloses a self-reaction type multipurpose mechanical limit anti-lock device and a method. The self-reaction type multipurpose mechanical limit anti-lock device comprise a base shell, asuspension shaft, a limit anti-lock shaft, a limit anti-lock sleeve, a sliding shaft and an unlocking device, wherein the base shell forms a storage cavity; the diameters of the suspension shaft, thelimiting anti-lock shaft and the sliding shaft are the same; the inner diameter of the limiting anti-lock sleeve is more than twice that of the suspension shaft; the suspension shaft and the limitinganti-lock shaft are horizontally, parallelly and fixedly arranged in the middle of the storage cavity; the limiting anti-lock shaft is positioned on the right side of the suspension shaft, and a space is reserved between the limiting anti-lock shaft and the suspension shaft; a limiting anti-lock sleeve is hung on the suspension shaft in a sleeving mode; when the limiting anti-lock sleeve is in anatural hanging state on the suspension shaft, the outer wall of the limiting anti-lock shaft is tangent to the limiting anti-lock shaft; a sliding waist-shaped groove is formed in the lower part of the base shell; and the sliding shaft is slidably arranged in the sliding waist-shaped groove. According to the self-reaction type multipurpose mechanical limit anti-lock device, a novel limiting anti-lock structure is adopted, pure machinery automatically triggers the anti-lock, the reaction is rapid and reliable, the service life is long, the installation and the maintenance are easy, hard impactis avoided in the whole process, the noise is small, the device is not prone to damaging, and the blocking condition is not prone to occurring.

Description

technical field [0001] The invention relates to a position-limiting and anti-locking device, in particular to a self-reaction multipurpose mechanical position-limiting and anti-locking device and method. Background technique [0002] The limit anti-locking devices currently used generally include two types. One is a hard limit anti-lock device with a purely mechanical structure. This kind of limit anti-lock mechanism is more traditional. The process action is blunt, with obvious impact and impact, easy to damage, loud noise, poor cushioning, and the anti-lock structure of the triangular block is prone to jamming, relying on the return spring, low life, and unstable effect; another It is an electric trigger type soft limit anti-locking device, which is triggered by a trigger switch or infrared rays, and cooperates with a relay or cylinder to drive a limit block to limit or anti-lock. Although the anti-locking process is sensitive and fast, it depends on the power supply, and ...

Although the anti-locking process is sensitive and fast, it depends on the power supply, and it will fail immediately when the power is off. Unable to guarantee the limit anti-lock effect after power failure, and the cost is high, and it is not easy to maintain
