Fall protection device

Abstract

The invention discloses a fall protection device, which comprises a lifting mechanism, a brake mechanism, a transverse beam and guide rails fixedly arranged at both sides of the transverse beam. The lifting mechanism is fixedly arranged at the upper part of the transverse beam; the upper part of the lifting mechanism is connected with a large lifting hook which is arranged at the end part of a steel wire rope; the lifting mechanism is connected with the brake mechanism through a link mechanism; the brake mechanism is arranged on the guide rails; the lifting mechanism consists of a box body and a lifting rod; the lifting rod is arranged in the box body; a press plate is fastened at the upper part of the box body; the box body is internally provided with a bottom board capable of moving along the inner wall of the box body up and down; the lower end of the lifting rod is fixed on the bottom board; the upper end of the lifting rod extends out of the press plate and is provided with a large lifting hook; a trigger spring is arranged on the lifting rod and located inside the box body; the upper end of the trigger spring is pushed against the press plate; and the lower end of the trigger spring is pushed against the bottom board. The fall protection device disclosed by the invention has flexible action, good safety performance and good using effects, can effectively avoid decoking equipment from falling due to the breakage of the steel wire rope, and is beneficial to being popularized and applied.

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] ...
