Crane hanging scaffold stall self-locking mechanism based on cable hoisting

Abstract

The invention relates to the technical field of cable installation, and discloses a crane hanging scaffold stall self-locking mechanism based on cable hoisting, the crane hanging scaffold stall self-locking mechanism comprises a base, the top of the base is fixedly connected with a first fixed column, the top of the first fixed column is movably connected with a first rotating disc, and the interior of the first rotating disc is fixedly connected with a first rotating shaft. For the crane hanging scaffold stall self-locking mechanism based on cable hoisting, when a stall phenomenon occurs in the hoisting process, the first metal ball makes contact with the negative electrode contact at the moment, magnetism is changed, the cross rod attracts the first metal ball at the moment, the second metal ball makes contact with the ball at the moment, the electro-rheological body is powered on, and therefore the effect that the electro-rheological body is changed into a solid state from a liquidstate is achieved. At the moment, a limiting column is clamped in a first groove under the action of centrifugal force and an electro-rheological body, a second rotating disc stops rotating at the moment, a first rotating shaft further stops rotating, and therefore the effects of stall self-locking of the hanging scaffold and sudden falling prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of cable installation, in particular to a stall self-locking mechanism for a suspension plate of a crane based on cable hoisting. Background technique [0002] In the process of cable laying and installation, it is often necessary to use a crane to hoist the cable. Due to the heavy weight of the cable, frequent work may cause mechanical fatigue to the hoisting device, resulting in a stall phenomenon, that is, a rapid drop during the lifting process. At this time, the cable will endanger the lives of the surrounding workers, and how to make the hanging pan stall and self-lock to prevent sudden fall has become an important problem. Therefore, we propose a stall self-locking mechanism for the suspension pan of the crane based on cable hoisting. .

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stall self-locking mechanism of the crane pan based on cable hoisting, which has the advantages of stall self-locking of the suspension and prevents sudden fall, and solves the problem of heavy cables and frequent work. It will cause mechanical fatigue of the hoisting device and cause a stall phenomenon, that is, the rapid decline during the lifting process, and the dropped cable will endanger the lives of the surrounding workers at this time.
