Automatic cable tensioning device and method

Abstract

The invention relates to the field of traction winches, in particular to an automatic cable tensioning device and method.The automatic cable tensioning device comprises a cylinder body, a mounting frame and a control system, the two ends of the cylinder body are open, a first end cover and a second end cover are arranged at the two ends of the cylinder body respectively, a motor is arranged on the first end cover, and one end of a first lead screw is arranged on an output shaft of the motor; a first sliding shoe and a second sliding shoe are arranged in the cylinder body, the other end of the first lead screw penetrates through the first end cover and the first sliding shoe and is located in the cylinder body, the first sliding shoe is in threaded connection with the first lead screw, a spring is arranged between the first sliding shoe and the second sliding shoe, and a pressure sensor is arranged on the second sliding shoe. The other end of the sliding rod penetrates through the second end cover to be connected with the second sliding shoe, a tensioning wheel is arranged on the installation frame, and the control system is connected with the motor and the pressure sensor. According to the automatic tensioning device, automatic tensioning control over the cable can be achieved, and the situations of cable cutting, slipping, disorder or cable jumping, cable falling and the like in the cable winding and unwinding process are prevented.

Description

technical field [0001] The invention relates to the field of traction winches, in particular to an automatic cable tensioning device and method. Background technique [0002] At present, in the process of deploying and recovering marine equipment, due to the changeable marine environment, the traction winch is affected by external factors such as wind and waves, and the cable is often in a state of slack and excessive tension. This situation will affect the deployment and recycling. adversely affect the process. Especially when the cable is in a slack state, the winch can easily lead to disorder or jumping of the cable in the process of arranging the cable, which not only requires the staff to re-arrange the cable, but also affects the normal use of the winch. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is that the winch easily leads to disorder or skipping of the cables during the arranging process. In order to solve this...

Problems solved by technology

[0002] At present, during the deployment and recovery of marine equipment by winches, due to the changeable marine environment, the traction winch is affected by external factors such as wind and waves, and the cables are often in a state of relaxation and over tension. adverse effect on the process

Especially when the cable is in a slack state, the winch will easily lead to cable disorder or jumping during the pulling process, which not only requires the staff to re-stretch, but also affects the normal use of the winch.
