Lifting appliance mechanical locking and fixing device

Abstract

The invention discloses a lifting appliance mechanical locking and fixing device comprising a square fixing frame. The fixing frame is composed of longitudinal beams and a transverse beam. The transverse beam is provided with a mechanical lock, sliding grooves are formed in the position, on the inner sides of the longitudinal beams, of the two sides of the fixing frame, sliding blocks are arrangedin the sliding grooves, the two sliding blocks are connected through angle aluminum, the sliding blocks are provided with connecting rods in the direction opposite to the angle aluminum, the ends ofthe connecting rods are provided with claw hands, a rocking arm is connected to the angle aluminum, and the other end of the rocking arm penetrates outside the mechanical lock. The device has the beneficial effects of the simple structure, good stability and high safety.

Description

technical field [0001] The invention belongs to the technical field of mechanical slings, and in particular relates to a mechanical locking and fixing device for a sling. Background technique [0002] As a kind of cargo grabbing and transportation equipment, spreaders are widely used in cargo handling and short-distance cargo transportation between various factory warehouses; currently, spreaders commonly used in automobile front axle assembly workshops are mainly divided into electromagnetic spreaders, Manipulator spreader, vacuum lifter, hydraulic lifter and hook spreader, etc. The electromagnetic spreader mainly operates by electromagnetic force. The electric power is sufficient, but it is easily disturbed by the fluctuation of the external electromagnetic force, and it will stop when the power is disconnected; the manipulator spreader is clamped by gravity, and it is easy to shake and slip during the lifting process. Phenomenon, there is a great potential safety hazard;...

AI Technical Summary

Problems solved by technology

The electromagnetic spreader mainly operates by electromagnetic force. The electric power is sufficient, but it is easily disturbed by the fluctuation of the external electromagnetic force, and it will stop when the power is disconnected; the manipulator spreader is clamped by gravity, and it is easy to shake and slip during the lifting process. Phenomenon, there is a great potential safety hazard; when the vacuum lifter absorbs the item, the surface of the item is required to be flat and smooth, and it is easy to fall off; the structure of the hydraulic lifter is complex, but the item is easy to fall off, and the fault is more likely to occur

[0003] Therefore, it is necessary to provide a mechanical locking device for the lifting device in view of the fact that the existing lifting device is prone to shaking and slipping during the lifting process.
