Abstract
The utility model provides a horizontal underground wheel type self-adaption pipeline crawl device, and belongs to the technical field of oil and gas development. The crawl device is in a slender shape as a whole and mainly comprises a shell body, a drive motor, support drivers and a connecting frame. All parts are directly or indirectly installed on the shell body of a rack. Two groups of relatively independent support drive mechanisms are the most important part. According to the diameter size of a wall hole, the mechanisms can automatically open or shrink to a certain extent under the effect of pretightening force and then starts to compress driven wheels installed on the mechanisms on the well wall. The crawl device is supported on the well wall through two supporting drivers provided with drive wheels and the driven wheels. Power output and transmission of the crawl device are completed through the drive motor veering a drive mechanism and wheel sets of the supporting drive mechanisms. The crawl device can crawl inside the well eye with changeable diameters and avoid the occurrence of accidents of side turn and the like.

Description of drawings
Fig. 1 is the structural representation of wheeled self-adapting pipe crawl device under the horizontal well of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model relates to a kind of device of the wheeled pipe crawling device of self adaption of carrying for the horizontal well downhole instrument.Integral body is elongate, mainly contains housing, drive motor, support drive machine and link press span and forms, and all loseing is on the housing that directly or indirectly is installed in as frame.Two groups of relatively independent support driving mechanisms are most crucial loseing, and this mechanism can be afterwards under the effect that pretightening force is arranged, and automatically open or shrink certain degree according to the diameter dimension of well, and follower mounted thereto is begun compressing on the borehole wall.Crawl device just is supported on the borehole wall by two support drive levels that driving wheel and follower are installed.The power of crawl device output and to transmit be by driving electromechanics, tooth combination and driven combination on commutate a driving mechanism and the support driving mechanism come order to finish.This crawl device can be creeped in the well that straightens the footpath, and the accident such as rollover can not occur.
Specifically referring to Fig. 1, wheeled self-adapting pipe crawl device under the described horizontal well, at housing or machine the power arrangement is installed, driving mechanism and driving actuator, the relatively independent support driving mechanism of formation that drives that actuator initiatively opens according to well or pipe diameter and the supporting mechanism regained is combined into one, the both sides of two support driving mechanism skeleton same points morning respectively symmetry are installed in the power plant rear end, be connected with the rotating pin form between power plant and the support driving mechanism, and by tooth combination transmission power be input to driving wheel and carry out purpose to reach row.
Further, be equipped with the support driving mechanism that two diagonal angles can be out of shape on the described housing, this support driving mechanism is formed by strut and one group of wheel combination driving mechanism.Each group support driving mechanism is fixed on the both sides of the same point of skeleton, symmetrical placement.Driving cog is settled respectively in each chain group driving mechanism shell fixed position on skeleton.Each chain group driving mechanism and main cover are connected by screw.Be equipped with at housing and connect frame, and commutation one driving mechanism that can slide along the housing axis with link press span is installed on the link press span.
And housing is by pre-tightening mechanism is arranged.Relatively independent between each support driving mechanism, reach the output stable purpose of advancing synchronously by driving force.Pre-tightening apparatus has been realized the protective value of pretension to whole skeleton.Carry out the chain built-up section of transmission of power, input end is connected by tooth, and output terminal then transmits by multiple tooth combination and finally reaches on the external tooth.Be connected by screw at each group driving mechanism and limb.
