Technical Field

The invention relates to a pipeline operation vehicle, in particular to a traction vehicle which is arranged in a power pipeline, a communication line pipeline and a transmission pipeline and is used for assisting operation in the pipeline.

Background

Taking communication line pipelines, power pipelines, transmission pipelines and the like as examples, when the three-dimensional positioning measurement is carried out on the pipelines, a steel wire line is firstly threaded, and the steel wire line is taken as a guide to pull the three-dimensional gyroscope measuring instrument to walk and position the pipeline for measurement. The existing steel wire threading operation generally uses a pipe dredging device. However, the channel is large in size and heavy in weight, threading operation is usually completed by more than 5 persons, operation is heavy, time and labor are wasted, and operation efficiency is low.

Disclosure of Invention

The invention aims to change the pipeline threading operation mode, further improve the automation capacity of threading operation, improve the pipeline threading operation efficiency and operation quality, and reduce the operation labor cost, and provides a pipeline threading tractor.

The technical scheme of the pipeline threading tractor provided by the invention mainly comprises the following technical contents: a pipeline threading tractor comprises a central body and two driving wheel trains arranged on the front and the back of the central body and matched with the inner wall of a pipeline in a rolling manner, wherein each driving wheel train comprises three driving wheel sets, and the three driving wheel sets are radially arranged on the central body in a regular star shape by taking the central body as the center.

In order to make the pipeline threading tractor suitable for the operation of pipelines with different pipe diameters, one preferable technical means in the whole technical scheme is that the central vehicle body is a lead screw, the driving wheel system is an adjustable wheel system according to the pipe diameter of the pipeline, and the central vehicle comprises a central main body positive tripod 4 fixed between a front end plate and a rear end plate, a central rod adjusting bolt 11, an adjusting ring 8 sleeved on the central rod adjusting bolt and adopting right-angle thread coupling, and the like.

The adjusting rotary adjusting hand wheel 10 is adjusted to drive the adjusting bolt 11 of the center rod to rotate, so as to drive the adjusting ring sleeved on the bolt to move forwards and backwards, drive the wheel carrier connecting rod 6 hinged between the adjusting ring 10 and the wheel carrier combination 4, lift the wheel carrier combination 4 forwards to increase the adaptive pipe diameter or lower the wheel carrier combination 4 backwards to reduce the adaptive pipe diameter, realize that the inner diameter of the adaptive pipe diameter can be continuously adjusted between 90mm and 300mm, and the adjusting rotary adjusting hand wheel is suitable for different pipe diameters.

According to the technical scheme of the pipeline threading tractor, the central vehicle body is stably supported in the center of the pipeline by the three driving wheel sets of the front driving wheel train and the rear driving wheel train, the central vehicle body is driven by the driving wheel sets and walks in the pipeline at the line position kept in the pipeline, the threading operation quality and the threading operation efficiency of the traction line are greatly improved, the operation is time-saving and labor-saving, the technical scheme also has the advantages of small size and light weight, the pipeline threading tractor can be completed by only one or two persons, and the operation cost is greatly reduced.

Detailed Description

An implementation structure of the pipeline threading tractor provided by the invention is shown in the figure. The threading tractor consists of a central tractor body 2 and two driving wheel trains A, B which are arranged on the central tractor body 2 in front and at back and roll on the inner wall of a pipeline 1, each driving wheel train A, B comprises three driving wheel sets 3, each driving wheel set 3 consists of a wheel carrier 4 and a roller 5 at the outer end of the wheel carrier 4, and the three driving wheel sets 3 are arranged on the central tractor body 2 in a positive star shape in the radial direction by taking the central tractor body 2 as the center; a direct current motor and a battery for driving the connecting roller 5 are arranged in the wheel frame 4 of each driving wheel set 3, the central vehicle body 2 is supported by the front driving wheel train, the rear driving wheel train and each driving wheel train in a radial regular triangle manner, as shown in figure 2, the roller 5 is driven by the direct current motor, and a traction wire is guided to automatically pass along the pipeline 1 to complete the traction of the steel wire.

On the basis of the above integral structure, in order to make the pipeline threading tractor suitable for pipeline operations with different pipe diameters, the driving wheel train A, B is a pipe diameter adjustable wheel train, one embodiment of which is configured as shown in fig. 3, the central vehicle body 2 is set as a lead screw, the driving wheel train A, B of the adjustable wheel train comprises a wheel carrier 4, an adjusting ring 8 and a wheel carrier connecting rod 6, the adjusting ring 8 and the central vehicle body 2 of the lead screw structure form a lead screw nut pair, a rotary adjusting hand wheel 10 is arranged at the outer end of the lead screw, a wheel train lantern ring 8 is radially and freely sleeved on a central rod 11 between the rotary adjusting hand wheel 10 and the lead screw, the wheel carrier 4 is hinged on the adjusting ring 8, the wheel carrier connecting rod 6 is connected between the adjusting ring 8 and the wheel carrier 4, and the three driving. One hand rotates the rotary adjusting hand wheel 10, the other hand holds the wheel carrier 4 to prevent the wheel carrier from moving along with the rotation of the screw rod, the screw rod forces the adjusting ring 8 to move left and right along the central vehicle body 2, the wheel carrier 4 is driven by the wheel carrier connecting rod 6 to drive the roller 5 to radially expand or retract along with the traction of the adjusting ring 8, and the radial radius is adjusted and changed in the radial range between the maximum radial direction M and the full retraction position according to the size of the actual pipe diameter of the pipeline so as to be suitable for pipelines with different pipe diameters.
