Fall protection device

Abstract

The invention discloses a fall prevention device, which comprises a lifting mechanism, a braking mechanism, a beam and guide rails fixedly installed on both sides of the beam, the lifting mechanism is fixedly installed on the upper part of the beam, and the upper part of the lifting mechanism and the end of the steel wire rope are provided The lifting hook is connected, the lifting mechanism is connected with the braking mechanism through a linkage mechanism, and the braking mechanism is installed on the guide rail; the lifting mechanism is composed of a box body and a lifting rod, and the lifting rod is installed in the box body, and the upper part of the box body A pressing plate is fastened, and a bottom plate that can move up and down along the inner wall of the box is arranged in the box body. The lower end of the lifting rod is fixed on the bottom plate, and the upper end of the lifting rod extends out of the pressing plate and is equipped with a lifting hook. The trigger spring is located inside the box body, the upper end of the trigger spring leans against the pressing plate, and the lower end of the trigger spring leans against the bottom plate. The invention has the advantages of sensitive action, good safety performance and good use effect, can effectively avoid the occurrence of falling accidents of decoking equipment caused by broken steel wire ropes, and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to a fall prevention device, which is applied in the technical field of fall prevention of decoking equipment in a delayed coking device in the petrochemical industry, and is used to prevent the decoking equipment from falling due to broken wire ropes. Background technique [0002] At present, the upper part of the decoking equipment in the delayed coking unit is connected to one end of the wire rope, and the other end of the wire rope is fixed on the winch drum of the drilling rig, and the up and down movement is realized by the winch and the wire rope. However, there are certain defects in safety. When the wire rope breaks, the decoking equipment falls to the ground instantly, which not only causes direct equipment loss, but also may cause damage to other equipment and personnel on the ground, which constitutes a serious threat to the safety production of the entire equipment. Great threat. Contents of the invention [0003] ...
