Vertical lifting and locking device

Abstract

The invention relates to a lifting and locking device. The vertical lifting and locking device is composed of a vertical lifting mechanism and a locking mechanism, and is characterized in that the vertical lifting mechanism includes a fixed rack (2), a left lifting gear (1), a left motor, and a left bearing platform frame (17 ), the right lifting gear (22), the right motor, the right bearing platform frame (23), the left lifting gear (1) meshes with the teeth on the left end of the fixed rack (2), the right lifting gear (22) and the fixed gear The teeth on the right end of the bar (2) are meshed, the left lifting gear (1) is connected with the output shaft of the left motor, the right lifting gear (22) is connected with the output shaft of the right motor, and the left motor is fixed on the left bearing platform frame (17), the right motor is fixed on the right bearing platform frame (23), and the left bearing platform frame (17), the right bearing platform frame (23) are connected with the bearing platform respectively; locking mechanism. The invention has the characteristics of large carrying weight, high working efficiency, safety and reliability in static state.

Description

technical field [0001] The invention belongs to the technical field of hoisting and transportation, and in particular relates to lifting and locking devices for industries such as shipping, hoisting, oil exploitation, equipment installation, and construction engineering. Background technique [0002] The vertical lifting mechanism is an independent transmission device. It usually consists of active driving components, driven lifting components, etc. It is often used between two working faces that are not on the same level to transport goods. [0003] Common elevator mechanism principles include gear-rack type, spiral pair type, hydraulic type, rod folding type, wire rope traction type, etc. [0004] The locking mechanism is an independent device that maintains a static state. It is usually composed of locked components, locking parts, racks, etc. [0005] The common principles of locking mechanisms include using external pressure, using locking pins, using the dead point...

AI Technical Summary

Problems solved by technology

[0006] In the lifting mechanism, the rack and pinion type can transmit a large force, and the lifting space can theoretically be infinite; the force transmitted by the screw pair and the hydraulic type can be large, but the lifting space is small; the folding type of the rod can have a large lifting space , but the transmitted force is relatively small; the force transmitted by the wire rope traction can be large, and the lifting space can also be large, but its stability is poor, and the control is not appropriate, which will cause the object to shake during work.

[0007] At present, most of the ship lifts used in domestic rivers use wire rope traction type lifting mechanism. In order to avoid shaking of objects during work, a slow lifting method is adopted, which takes a long time to lift once, and friction is used when the equipment is stationary. self-locking way
