Problems solved by technology

However, in the prior art, most of the wire rope anti-loosening devices are mechanical structures, and the traditional mechanical limit sensor is used for limit triggering. This kind of device is not only slow in response, but also has low reliability in use, but also has a complex structure and mechanical wear during use. Large, high failure rate, poor use effect

Abstract

The invention relates to the field of crane manufacturing technology, and particularly relates to a looseness-preventing rope protection device of a steel wire rope used for a crane, which is characterized in that: the looseness-preventing rope protection device comprises a tension adjusting base plate with an adjustable height; the tension adjusting base plate is connected with a stressed spindle through a connecting frame which is arranged on the tension adjusting base plate, the peripheral part of the stress spindle is connected with a steel wire rope guide wheel through a bearing, the inner part of the stressed spindle is provided with a pressure sensor which can sense the stressed state of the stress spindle, and an electrical signal output end of the pressure sensor is connected with a winch control circuit which is used for controlling a winch. The looseness-preventing rope protection device is fast in response, is safe and reliable in using, can effectively prolong the service life of the steel wire rope, and is simple in structure, low in failure rate and long in service life.

Description

technical field [0001] The invention relates to the technical field of crane manufacturing, in particular to a wire rope anti-loosening protection device for a crane. Background technique [0002] Cranes are widely used in the loading and unloading of cargo on board. In the process of unloading, in order to prevent the wire rope from being released too long, causing the wire rope to slack and bend, causing the wire rope to be disorderly arranged, intertwined, or even damaged during recovery, it is necessary to install a wire rope anti-loosening device. However, in the prior art, most of the wire rope anti-loosening devices are mechanical structures, and the traditional mechanical limit sensor is used for limit triggering. This kind of device is not only slow in response, but also has low reliability in use, but also has a complex structure and mechanical wear during use. Large, high failure rate, poor use effect. Contents of the invention [0003] The object of the prese...
