Embodiment Construction
[0018] The present invention is not limited by the following examples, and specific implementations can be determined according to the technical solutions and actual conditions of the present invention.
[0019] In the present invention, for the convenience of description, the description of the relative positional relationship of each component is described according to the layout method of FIG. 1 of the specification, such as: the positional relationship of front, rear, top, bottom, left, right, etc. It is determined according to the layout direction of the drawings in the description.
[0020] Below in conjunction with embodiment and accompanying drawing, the present invention is further described:
[0021] As shown in Figures 1, 2, 3, 4, and 5, the strut-type cylinder claw pulling tool includes a pulling claw cylinder and an inner support rod 1; Claw split groove 2, the bottom of the claw split groove 2 extends to the middle of the pulling claw cylinder, the pulli...

The invention relates to the technical field of pulling tools, and is a pole-type cylinder claw pulling tool, which includes a pulling claw cylinder and an inner support rod; the right end surface of the pulling claw cylinder is distributed with claws with openings facing the right Groove, the groove bottom of the claw splitting groove extends to the middle of the pulling claw tube, the pulling claw tube on the left side of the groove bottom of the claw splitting groove forms a pulling cylinder, the right side of the groove bottom of the claw splitting groove The pulling claw tube forms elastic claws arranged in a ring. The invention has a reasonable and compact structure and is easy to use. By pushing the inner support rod to the right, the inner tapered surface of the claw can be squeezed to make the right end of the elastic claw open outwards to clamp the cylindrical workpiece, or by pushing the inner support rod to the left The right end of the elastic claw shrinks inwards to clamp the shaft workpiece, so that the workpiece can be pulled out. It is suitable for working conditions such as limited space and high tension. It has the advantages of simple structure, low manufacturing and maintenance costs, simple and reliable locking mechanism, and long service life. long features.
Description
technical field [0001] The invention relates to the technical field of pulling tools, and relates to a pole-type cylinder claw pulling tool. Background technique [0002] The vertical drilling system is a downhole closed-loop drilling tool integrating machinery, electricity and hydraulics. Its structure is complex, the working environment is harsh, and it needs to work for a long time in the environment of high temperature, high pressure and mud immersion. When going out of the well for maintenance, it is difficult to disassemble the components, especially to pull the components out from the body. Pulling tools are essential tooling during vertical drilling system assembly and maintenance. The existing pulling tools currently in use have the following deficiencies in actual use: the structure is relatively complex, the cost of manufacturing and maintenance is high, the spring locking mechanism is prone to failure, the service life is short, and the reliability is low. Too...
