Flat belt dragger

Abstract

The invention discloses a flat belt dragger which comprises a bracket, an upper caterpillar band and a lower caterpillar band, wherein the upper caterpillar band and the lower caterpillar band are symmetrically arranged, left wheels are mounted at one ends of the upper and lower caterpillar bands, right wheels are mounted at the other ends of the upper and lower caterpillar bands, rotating shaftsare connected to the middle parts of the left and right wheels connected to the lower caterpillar band, and reducers are connected to the same ends of the rotating shafts, separately. A phenomenon ofslip as a result of insufficient contact surfaces or friction forces between the caterpillar bands and a sea cable when the two caterpillar bands drag the sea cable because an existing flat belt dragger is short of a mechanism for clamping the two caterpillar bands can be solved, and a condition that the caterpillar bands are likely to take off or even damage as a result of insufficient tension during operation because a mechanism for adjusting the tension of the caterpillar bands is in short is avoided. Meanwhile, a condition that the existing flat belt dragger often needs a plurality of driving motors in achieving forward and backward traction is avoided.

Description

technical field [0001] The invention relates to the field of tractors, in particular to a flat belt tractor. Background technique [0002] In the course of receiving and unwinding the submarine cable, it is necessary to use a flat belt tractor for traction, but the existing flat belt tractor still has certain defects in use. First of all, due to the lack of a The clamping mechanism makes it easy for the two crawlers to slip due to insufficient contact surface or insufficient friction between the crawler and the submarine cable during the process of pulling the submarine cable, and due to the lack of a mechanism for adjusting the tension of the crawler, As a result, the track is prone to detachment or even damage due to insufficient tension during operation. At the same time, the existing flat belt tractors often need to be equipped with multiple drive motors when they need to be able to achieve forward and reverse traction, resulting in traction. The production cost is high...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a flat belt tractor, which can solve the problem that the existing flat belt tractor lacks a mechanism for clamping between the two crawlers during the use of the existing flat belt tractor, so that the two crawlers are in the process of pulling the submarine cable. It is prone to slipping between the track and the submarine cable due to insufficient contact surface or insufficient friction, and due to the lack of a mechanism to adjust the tension of the track, the track is prone to detachment or even damage due to insufficient tension during operation At the same time, because the existing flat belt tractors often need to be equipped with multiple drive motors when they need to be able to achieve forward and reverse traction, which leads to the problem of high production costs of the tractor
