Fixing device and method for spliced operation ladder

Abstract

The invention discloses a fixing device for a spliced operation ladder. The fixing device comprises a supporting seat and two fixing frames, the two fixing frames are located above the supporting seat, baffles are installed on the two sides of the supporting seat, a plurality of supporting frames are vertically welded between the two baffles at equal intervals, and a sleeve groove is formed between every two supporting frames. The fixing device for the spliced operation ladder has the beneficial effects that the operation ladder is placed in the sleeve grooves, meanwhile, safety protection iscarried out on the operation ladder through the baffles, so that workers are better protected during operation, and the use safety of the spliced type operation ladder is improved; a second motor at the bottom of a fixed seat drives a gear to roll, the gear meshes with a hobbing to roll, the fixing frames are driven to move to be close to ladder feet on the two sides of the operation ladder, hydraulic columns on the fixing frames push fixing plates to move under the action of hydraulic cylinders, the ladder feet on the side wall of the operation ladder are clamped and fixed through the two fixing plates on the fixing frames, and the construction safety of the workers on the operation ladder is greatly improved.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a spliced ​​working ladder, and belongs to the technical field of application of safety devices for detection of vacancy of getting off platforms. Background technique [0002] The spliced ​​working ladder is used more and more frequently in daily life. The spliced ​​working ladder is usually in the shape of a "herringbone". The staff can work at a higher position on the spliced ​​working ladder. The spliced ​​working ladder is matched with the fixing device. It is used more and more, and the working ladder is clamped and fixed by the fixing device, so as to improve the safety of the working ladder in use. [0003] The existing fixing devices for splicing work ladders still have great defects in use. The existing fixing devices for splicing working ladders can only clamp and fix working ladders of the same specification and width , the scope of adaptation is small, and the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing fixing devices for splicing work ladders can only clamp and fix the working ladders of the same specification and width, and the range of adaptation is small; The ladder is not fixed enough, which leads to poor safety of the working ladder; after the existing fixing device is fixed to the working ladder, the position of the working ladder cannot be adjusted, and the flexibility of use is very poor, which seriously affects the staff working on the working ladder efficiency and safety issues, and a fixing device for splicing working ladders is proposed
