Overturning double-door clamping lock for lift platform

Abstract

The invention discloses an overturning double-door clamping lock for a lift platform which comprises a first door leaf and a second door leaf, wherein the second door leaf is rotationally arranged atthe left side of the first door leaf, and the edge of the left end of the first door leaf is fixedly provided with a first vertical door frame. A first horizontal door frame is fixedly arranged at theedge of the top end of the first door leaf, an elastic tensioning device is arranged near the top end portion of the front end face of the first vertical door frame, and the outer side of the upper end of the first horizontal door frame is sleeved with a double-door clamping lock body. Through the installed double-door clamping lock body, the double-door can be locked, so that the door leafs of the double-door cannot exceed the table surface of the lift platform and the danger of the door leafs colliding with other equipment outside the lift platform can be avoided. Through the installed elastic tensioning device which can apply tension to a tensioning rope, and the guide effect of a guide wheel, the tensioning rope can apply tension to the double-door clamping lock body, so that the double-door can be locked more effectively.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a flip-type double door latch of a lifting platform. Background technique [0002] Today, with the rapid development of the national economy, construction machinery such as construction elevators has begun to play a huge role in more and more construction fields, especially for large projects and high-rise building sites, the use of construction elevators is particularly important; it can greatly improve productivity. and save labor time. People have higher and higher comprehensive requirements for the performance, efficiency, load capacity, energy saving, maintenance and other aspects of the elevator. When the elevator is lifting, it is necessary to use double doors to ensure the safety of the lifting. Contents of the invention [0003] (1) Technical problems to be solved: [0004] At present, during the use of the elevator, it is necessary to install double doors ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies in the prior art, a flip-type double-door latch of the lifting platform is proposed to solve the problem that the double-leaf door installed on the existing lifting platform proposed above is not equipped with a double-door latch, which causes the double-leaf door to perform lifting operations on the lifting platform When the displacement is too large, the door leaf of the double door will exceed the table of the lifting platform, and the door leaf beyond the table of the lifting platform may collide with other equipment outside the lifting platform, reaching the lifting platform. The effect of safe lifting
