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 with reference to the accompanying drawings and specific embodiments.

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

[0023] like figure 1 , figure 2 As shown, the structure of the clamping unit includes a chuck body 3, the through hole of the shaft center of the chuck body 3 is called the middle wire hole 2, and the front end surface of the chuck body 3 is installed with three sets of jaws 1 centripetally, The inner circular surfaces of the three groups of jaws 1 together form an arc-shaped clamping seat 25 , each group of jaws 1 is provided with a countersunk head adjusting bolt 24 , and the three groups of jaws 1 are provided with a jaw drive 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 thre...

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 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 well sections with large well inclination and long horizontal well sections, the existing surface pipeline traction It has become difficult to run downhole instruments downhole for logging, relying on the gravity of the equipment itself to lower downhole instruments to the bottom of the well, and corresponding technologies 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 there are some deficiencies to a certain extent, such as poor reducing ability, low adhesion to the well wall or pipe wall, easy to slip and jam, It is suita...
