A cable pressing device

Abstract

The invention discloses a cable pressing device, and belongs to the field of machines for ships. The cable pressing device comprises a driving component, a supporting component and a cable pressing component; the supporting component comprises a supporting frame, a transmission shaft and a guide shaft, the two ends of the transmission shaft are rotationally installed on the supporting frame, an output shaft of the driving component is connected with one end of the transmission shaft, the guide shaft and the transmission shaft are parallel, and the two ends of the guide shaft are fixed to the supporting frame; the cable pressing component comprises a cable pressing assembly and a sliding piece, the cable pressing assembly is fixedly installed on the sliding piece, and a threaded hole and a through hole are formed in the sliding piece; and the transmission shaft is inserted into the threaded hole, the transmission shaft and the threaded hole are in threaded fit, the guide shaft is inserted into the through hole, and the guide shaft and the through hole are in clearance fit. The cable pressing device solves the problem of cable drooping.

Description

technical field [0001] The invention belongs to the field of marine machinery, in particular to a cable pressing device. Background technique [0002] The detector is the key equipment on the exploration ship, and the exploration ship realizes the exploration of the seabed by lowering the detector. [0003] When lowering the detector, it is necessary to connect the detector with the cable stretched out from the winch group arranged on the deck of the survey ship. The winch group usually includes a cable storage winch and a traction winch, wherein the cable storage winch is used for storing cables (the Multiple layers of cables can be wound on the drum), and the traction winch is used to retract and release the cables (only one layer of cables is wound on the drum of the traction winch). [0004] Due to the limitation of the cable material, the cable cannot withstand a large pulling force, so the traction winch cannot exert sufficient pre-tightening force on the cable. Once ...

AI Technical Summary

Problems solved by technology

[0004] Due to the limitation of the cable material, the cable cannot withstand a large pulling force, so the traction winch cannot exert sufficient pre-tightening force on the cable. Once the traction winch stops working, the traction force acting on the cable disappears, and the cable is easily under the action of gravity. It will hang down from the traction winch by itself, and in severe cases, even the cable skipping and rope breaking will occur. At this time, workers need to rewind the cable on the traction winch, resulting in low operating efficiency
