Abstract

The invention relates to an adapter malfunction prevention protective system comprising an adapter and a hydraulic control system. The adapter comprises a frame and a retaining claw unit pivoted to the frame. The hydraulic control system comprises a hydraulic cylinder, an electromagnetic valve and an oil tank. One end of the hydraulic cylinder is welded to the frame, and the other end of the hydraulic cylinder is connected to the retaining claw unit through a connector and drives the retaining claw unit. The hydraulic cylinder is connected with the oil tank through the electromagnetic valve. The adapter malfunction prevention protective system is reasonable in design, simple in structure, convenient to mount and maintain, simple to operate, low in production cost, and capable of operating reliably and being mounted with no influence on daily operation of a cage; scratch of the cage, caused by malfunction of an adapting cylinder, can be effectively prevented.

Description

[0001] technical field [0002] The invention relates to a mine cage lifting protection device, in particular to a protection system for preventing malfunction of a receiving device, and belongs to the technical field of mining equipment. Background technique [0003] When the auxiliary well cage of the prior art is in normal operation, the cage will be scraped due to the misoperation of the oil cylinder during the up and down operation, which poses a major threat to safe production. [0004] Therefore, in order to solve the above technical problems, it is indeed necessary to provide an advanced protection system for preventing malfunction of the receiving device, so as to overcome the above-mentioned defects in the prior art. Contents of the invention [0005] In order to solve the above problems, the object of the present invention is to provide a protection system for preventing malfunction of the receiving device, which is simple in structure, safe and reliable, and ea...
