The invention relates to a top drive guide rail plate butting device which mainly solves the problems of low butting and removal efficiency, high installation and removal cost, complex operation and requirement of high-attitude operation of the traditional guide rail plate butting device. The top drive guide rail plate butting device is characterized in that an adjusting main part comprises an adjusting back plate (3) and an adjusting plate (4), the top end of the adjusting back plate (3) is provided with a connecting lifting lug (5), and the adjusting plate (4) is inserted into the adjusting back plate (3) and is connected with the adjusting back plate (3) through bolts; the lower end of the adjusting plate (4) is hinged with a butting head (1), the lower end of the butting head (1) is a ball, and a guiding steel wire rope (6) is fixed in an axial hole of the butting head (1); a two-stage stepped hole with a small top and a large bottom is arranged in a butting sleeve (2), the lower part in the stepped hole is provided with a return spring (7), the upper end of the return spring (7) is provided with a spring seat (8), at least three slips (9) are connected outside the spring seat (8), and limiting stands are arranged in the upper parts of the slips (9). The top drive guide rail plate butting device not only has high installation and removal efficiency and low installation and removal cost and is simple to operate and but also is free from high-altitude operation.
Description
Technical field: [0001] The invention relates to a butt joint device used for the guide rail plate of a top drive drilling rig, in particular to a butt joint device for the top drive guide rail plate. Background technique: [0002] With the exploration and development of oil and gas, the demand for top drive drilling rigs is becoming more and more urgent. The top drive device directly drives the drilling tool with power from the top of the derrick for rotary drilling, which changes the traditional rotary drilling method and can complete various drilling such as circulating drilling fluid, erecting, making up and breaking out, and back reaming. operating drilling rig. In order to prevent the top drive from rotating itself, it is necessary to slide the top drive up and down on the guide rail plate, which is vertically installed between the upper part of the derrick and the drill floor. The guide rail plate is composed of 5-7 joints, and each joint is 5-6 Meter. When moving ...
