Problems solved by technology
[0003] When the wire rope luffing electric crane is pulling the boom to do the luffing action, when the boom is raised upwards, there is a limit position. If the limit position is exceeded, the boom will collide with the tower body, which will cause the boom and the tower to collide. body damage
There are safety implications and reduced boom and tower life

The invention relates to a steel wire rope luffing electric arm rack anti-collision device. The device comprises a tower body, an lifting arm is hinged on one side of the tower body, a first pulley group is arranged on the top part of the lifting arm, a second pulley group is arranged on the top part of the tower body, a combined decelerator is fixed on the other side of the tower body through a fastener, the output terminal of the combined decelerator is connected to a steel wire rope, the steel wire rope orderly goes through the second pulley group and the first pulley group; a buffer device is arranged on the bottom of the lifting arm, wherein the buffer device comprises a buffer cushion, and a plurality of anti-collision rams are alternately fixed on the cushion through fasteners. The device has the advantages of compact and reasonable structure, convenient installation, and low cost, effectively prevents the lifting arm from colliding the tower body when the lifting arm exceeds the maximum elevation angle through setting a buffer device, and thus protects the lifting arm and the tower body. The operational reliability is good and the safety is high.
Description
technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an anti-collision device for a wire rope luffing electric boom frame. Background technique [0002] A marine crane is a large deck machinery on a ship, and it is a device for loading and unloading cargo on a ship. [0003] When the wire rope luffing electric crane pulls the boom to do the luffing action, when the boom lifts up, there is a limit position. If the limit position is exceeded, the boom will collide with the tower body, which will cause the boom and the tower to collide. body damage. There is a safety impact, which reduces the service life of the boom and the tower. Contents of the invention [0004] In view of the above-mentioned shortcomings of the existing production technology, the applicant provides a steel wire rope luffing electric boom frame anti-collision device with reasonable structure, so as to effectively prevent the collision between the bo...
