The tractor of the invention adopts the technical scheme that the inner surface of the crawler belt is provided with the arc groove, the arc groove on the inner surface is used for increasing the friction force with the driving wheel, and the arc groove on the outer surface of the crawler belt is used for increasing the clamping force on the fireproof cable so as to eliminate the occurrence of slip accidents during traction.
Description
Technical Field
The invention relates to the field of tractors, in particular to an adjustable multi-groove crawler-type tractor.
Background
Two crawler-type tractors need to be used to pull in receiving, putting the cable working process of carrying out fireproof cable, but current crawler-type tractor is mostly flat belt because the track that adopts to lead to the phenomenon of skidding appearing in the in-process of pulling fireproof cable easily.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide an adjustable multi-groove type crawler-type tractor.
In order to solve the technical problems, the invention adopts the following technical scheme:
an adjustable multi-groove crawler-type tractor comprises a base and a linear guide rail arranged on the base, wherein a sliding block is movably arranged on the linear guide rail, an upper frame is fixed on the sliding block, a first driving wheel, a second driving wheel, a first driven wheel and a second driven wheel are symmetrically arranged on the same surface of the upper frame from top to bottom, the first crawler is arranged on the first driving wheel and the first driven wheel, the second crawler is arranged on the second driving wheel and the second driven wheel, a plurality of groups of pulley blocks which are symmetrically distributed are arranged in the first crawler belt and the second crawler belt, the pulley blocks are arranged on a piston rod of an air cylinder, the air cylinder is arranged on the upper frame, arc grooves are respectively formed in the inner surface and the outer surface of the first crawler belt and the inner surface and the outer surface of the second crawler belt, and the motor is installed on the other surface of the upper rack and drives the first driving wheel and the second driving wheel to rotate.
Compared with the prior art, the invention has the beneficial effects that:
the invention relates to an adjustable multi-groove crawler-type tractor, wherein arc grooves are formed in the inner surface of a crawler, the arc grooves in the inner surface are used for increasing friction force between the inner surface and a driving wheel, and the arc grooves in the outer surface of the crawler are used for increasing clamping force on a fireproof cable so as to eliminate slipping accidents during traction.

Detailed Description
Referring to fig. 1-4, an adjustable multi-groove type crawler tractor comprises a base 1 and a linear guide rail 2 mounted on the base 1, a sliding block 3 movably mounted on the linear guide rail 2, an upper frame 4 fixed on the sliding block 3, a first driving wheel 5, a second driving wheel 6, a first driven wheel 7 and a second driven wheel 8 symmetrically arranged on the same surface of the upper frame 4 up and down, a first crawler 9 mounted on the first driving wheel 5 and the first driven wheel 7, a second crawler 10 mounted on the second driving wheel 6 and the second driven wheel 8, a plurality of groups of pulley blocks 11 symmetrically distributed in the first crawler 9 and the second crawler 10, the pulley blocks 11 mounted on a piston rod of an air cylinder 12, the air cylinder 12 mounted on the upper frame 4, circular arc grooves 13 respectively arranged on the inner and outer surfaces of the first crawler 9 and the second crawler 10, the motor is arranged on the other side of the upper frame 4 and drives the first driving wheel 5 and the second driving wheel 6 to rotate.
The invention relates to an adjustable multi-groove type crawler-type tractor which is used for cable winding and cable unwinding of a fireproof cable, wherein in the work, a first driving wheel 5 and a second driving wheel 6 rotate under the drive of a motor and drive a first crawler 9 and a second crawler 10 which are connected with the first driving wheel and the second driving wheel to rotate, a cylinder 12 is started and drives a pulley block 11 which is connected with the cylinder to tightly clamp the fireproof cable by the first crawler 9 and the second crawler 10, in order to avoid slipping, arc grooves 13 are respectively arranged on the inner surface and the outer surface of the first crawler 9 and the second crawler 10, the arc grooves on the inner surface are used for increasing the friction force with the driving wheels, and the arc grooves on the outer surface of the crawler are used for increasing the clamping force on the fireproof cable. In order to meet the production requirements of products with different pipe diameters, the arc grooves 13 can be arranged in various ways, and in order to obtain a better clamping position, the upper frame 4 is movably connected with the base 1 through the linear guide rail 2, when fireproof cables with different pipe diameters are clamped, the position of the upper frame 4 on the base 1 can be moved to adjust the positions of the arc grooves 13 only by arranging a rotating handle or a motor on the base 1 and driving the sliding block 3 through a lead screw. The clamping device is reasonable in design, novel in structure and good in clamping force, and can effectively avoid slipping.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, so that any person skilled in the art can make changes or modifications to the equivalent embodiments using the above disclosure. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are still within the protection scope of the present invention, unless they depart from the technical spirit of the present invention.
