Description

Technical Field

[0002] A submarine cable traction device is a device used for traction of submarine cables. The existing submarine cable traction device includes a frame and a driving mechanism, a pulling mechanism and a pressing mechanism arranged on the frame; the driving mechanism includes a frequency conversion motor, a first driving gearbox arranged on the frequency conversion motor, a left pulling gearbox and a right pulling gearbox. When this kind of submarine cable traction machine is in use, when the submarine cable does not enter between the upper chain and the lower chain parallel to the upper chain and the lower chain, the submarine cable may rub against the frame. When the bending angle of the submarine cable is relatively large, the traction machine needs to overcome the bending angle of the submarine cable to pull the submarine cable, and the traction of the submarine cable is relatively laborious.

DETAILED IMPLEMENTATION MANNER

[0016] The present utility model will be specifically described below with reference to the accompanying drawings. As shown in the Figure 1 drawings, a universal submarine cable traction device includes a tractor frame 1. The upper part of the tractor frame 1 is provided with a main body of the tractor 2. U-shaped frames 3 are arranged on both sides of the main body of the tractor 2. Each of the U-shaped frames 3 is fixedly arranged with the tractor frame 1. Horizontal guiding rollers 4 are installed on the upper and lower sides inside each of the U-shaped frames 3 through nuts. The horizontal guiding rollers 4 are steel rollers with a rotating shaft and a roller body rotating relative to each other. A vertical guiding roller structure 5 is installed on one side of the tractor frame 1.
