Two crawler type tractor

Abstract

The invention discloses a two crawler type tractor. The two crawler type tractor comprises an upper moving frame, a lower fixing frame and a traction mechanism, wherein a plurality of slide rails arearranged on one side of the upper moving frame, the same ends of the plurality of the slide rails are all connected with a top frame, a plurality of oil cylinders are installed on the top frame, the bottom of each oil cylinder is connected with a telescopic rod, and each telescopic rod is connected into the slide rail on the corresponding position, and connected with the upper moving frame. The two crawler type tractor can solve the problems that a slipping phenomenon is easily caused in the traction process of a submarine cable due to the fact that most crawler belts used by an existing crawler type tractor are flat belts, the existing crawler type tractor is lack of a mechanism for adjusting the distance between each two adjacent crawler belts, and therefore the distance between each twoadjacent crawler belts is inconvenient to adjust; the existing crawler type tractor is lack of an abutting and limiting component when each two adjacent crawler belts clamp the submarine cable, and therefore slip is easily caused in traction; and all assemblies of a traction mechanism of the existing tractor need customized production, and therefore cost is high, and procurement is troublesome.

Description

technical field [0001] The invention relates to the field of tractors, in particular to a two-crawler tractor. Background technique [0002] In the process of receiving and unwinding the submarine cable, it is necessary to use two crawler-type tractors for traction, but the existing crawler-type tractors still have certain defects in use. First, because the crawlers used are mostly flat The belt is likely to cause slippage during the process of pulling the submarine cable, and the lack of a mechanism to adjust the distance between the two crawlers makes it inconvenient to adjust the distance between the two crawlers. The cable lacks tightening and position-limiting parts, so it is prone to slippage during traction, and each component of the traction mechanism of the tractor needs to be customized, which is costly and troublesome to purchase. [0003] Publication number is: the patent of CN204057451U discloses a kind of crawler tractor, compares with this application, can't ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a two-crawler tractor, which can solve the problem that the existing crawler tractors are mostly flat belts, which easily lead to slipping in the process of pulling the submarine cable, and lack of adjustment. The mechanism of the distance between the two crawlers makes it inconvenient to adjust the distance between the two crawlers, and the two crawlers lack clamping and limiting parts when clamping the submarine cable, which makes it easy to slip during traction , and each component of the traction mechanism of the traction machine still needs to be customized, the cost is high, and the procurement is also troublesome.
