Problems solved by technology

The hoisting ratchet locking device is controlled by manual control cable or linkage mechanism, which cannot be controlled automatically. If the manual control is not timely, it may cause the hoisting rotation of the hoisting machine to turn into the lowering arm rotation, thus causing the boom to lose control and cause an accident.

Abstract

The invention discloses an electromagnetic locking mechanism. The electromagnetic locking mechanism comprises an L-shaped base frame, the base frame comprises a transverse plate and a vertical plate,a horizontally-placed telescopic rod is arranged on the upper surface of the transverse plate, a fixed plate is arranged on the side face of the vertical plate, the left end of the telescopic rod is connected with a stop rod, the stop rod is vertically and obliquely arranged, the lower end of the stop rod is hinged to the telescopic rod, the stop rod upwards penetrates through the fixing plate tobe hinged to the fixing plate, pawls are arranged at the upper end of the stop rod, and the tail end of the stop rod is matched with the edges of the pawls; the right end of the telescopic rod penetrates through a fixing box, and the tail end of the telescopic rod is connected with an electromagnet; and a limiting ring is arranged on the part, extending into the fixing box, of the telescopic rod,and a first spring is arranged between the limiting ring and the inner wall, close to the electromagnet, of the fixing box. According to the electromagnetic locking mechanism, by means of the principle that the electromagnet is powered on to generate magnetism, the electromagnet can be powered on to generate magnetism only by pressing a switch of the electromagnet in time, the telescopic rod is attracted, thus linkage reaction is carried out to enable the stop rod to clamp the pawls, and pawl locking is achieved; and safety production accidents caused by untimely manual locking are avoided.

Description

technical field [0001] The invention relates to an electromagnetic locking mechanism, belonging to the technical field of mechanical locking. Background technique [0002] At present, in order to ensure the safety of the crawler crane, the luffing winch has a ratchet locking device. The ratchet locking device of the crawler crane winch is connected with the ratchet by a pull wire or a connecting rod mechanism, and the ratchet is stuck on the ratchet to form a ratchet lock. stop device. The hoisting ratchet locking device is controlled by manual control cable or linkage mechanism, which cannot be controlled automatically. If the manual control is not timely, it may cause the hoisting rotation of the hoisting machine to turn into the lowering arm rotation, thus causing the boom to lose control and cause an accident. Therefore, there is a need for an electromagnetic locking mechanism. Contents of the invention [0003] In order to solve the above-mentioned technical problem...
