Problems solved by technology

[0005] The purpose of the present invention is to provide a crawler-type self-adaptive pipeline crawler, which solves the problem that the prior art cannot adapt to the laying of cables with different pipe diameters in horizontal wells and extended-reach wells, the driving force is insufficient, and the crawling of curved pipelines cannot be overcome. Inconsistency, the problem of poor adhesion in the well section

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The structure of the crawler-type self-adaptive pipeline crawler of the present invention includes a clamping unit, a crawling unit and a control unit.

[0023] Such as figure 1 , figure 2 As shown, the structure of the clamping unit is to include the chuck body 3, the axial through hole of the chuck body 3 is called the middle wire-passing hole 2, and the front end surface of the chuck body 3 is equipped with three sets of claws 1, The inner circular surfaces of the three groups of claws 1 together form an arc-shaped clamping seat 25 , each group of claws 1 is provided with a countersunk adjusting bolt 24 , and the three groups of claws 1 are provided with a claw driving mechanism.

[0024] The structure and principle of the clamping unit are similar to the three-jaw chuck on the machine tool. The centripetal position of the three ...

Abstract

The invention discloses a tracked self-adaptation pipeline crawler. The tracked self-adaptation pipeline crawler comprises a clamping unit, a crawling unit and a control unit. The crawling unit comprises two caterpillar track unit sets, wherein two driven bevel gears, two tension wheels and a driving bevel gear are jointly connected with a bevel gear caterpillar track in a transmission mode to form one caterpillar track unit set. The control unit comprises an electrically controlled box; the electrically controlled box is further connected with all synchronous motors in a control mode; each synchronous motor is provided with a torque sensor. The tracked self-adaptation pipeline crawler solves the problems that an existing crawler in the prior art can not adapt to different-pipe-diameter cable paving in a horizontal well and an extended reach well, is not enough in driving force, can not crawl in a bent pipeline, is not consistent in inner side and outer side speed and poor in well section adhesive force, and can be applied to occasions like oil exploration and urban pipeline laying.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a crawler-type self-adaptive pipeline crawler. Background technique [0002] In oil drilling technology, horizontal wells and extended-reach wells have been developed rapidly. However, due to the limitation of wellbore conditions, for wells with large well deviation and long horizontal well sections, the existing surface pipeline traction It has become very difficult to put the downhole instrument down to the bottom of the well, relying on the gravity of the equipment itself to lower the downhole instrument to the bottom of the well. Corresponding technology and tooling are urgently needed to solve this problem. [0003] There are many existing ground pipeline tractors, and some underground crawlers have also appeared, but to a certain extent, there are some shortcomings, such as poor diameter changing ability, small adhesion to the well wall or pipe wall, easy slipping...
