Description

Technical Field

[0001] This utility model relates to the field of drilling, and in particular to a labor-saving tool using drilling slips in deep wells. Background Technology

[0002] Currently, during the drilling and completion of deep wells, the wellhead slips are used frequently and weigh 50-60 kilograms. In actual use, three people are required to lift and put them in to secure the drill bit. This results in high manpower consumption, is time-consuming and labor-intensive, and poses certain safety risks due to the close proximity of personnel to the wellhead during operation. Utility Model Content

[0003] The purpose of this invention is to provide a labor-saving tool for drilling deep wells using slips, which solves the safety risks associated with operation when the operator is close to the wellhead.

[0004] To achieve the purpose of this utility model, a labor-saving tool for drilling deep well slips is provided, comprising: slip control claw, fixed rod, horizontal axis, vertical axis, movable roller, operating rod, sleeve A, sleeve B, connecting rod, and handle. The slip control claw is rotatably connected to one side of the fixed rod via a hinge. The bottom surface of the other side of the fixed rod is fixedly connected to the upper surface of one side of the horizontal axis. The other side of the horizontal axis is rotatably connected to the middle end of the vertical axis via a pivot. The movable roller is installed on both sides of the vertical axis. The operating rod is rotatably connected to the middle end of the vertical axis via a pivot. Sleeve A is sleeved on the outside of the vertical axis. Sleeve B is sleeved on the outside of the operating rod. One side of the connecting rod is hinged to sleeve A, and the other side of the connecting rod is hinged to sleeve B. The handle is fixedly installed on the top of the operating rod.

[0005] As a preferred technical solution of this utility model, it includes: a fixing nut A, which is installed on both sides of the control claw of the clamp; and a fixing nut B, which is installed on both sides of the movable roller.

[0006] As a preferred embodiment of this utility model, the sleeve A has a central threaded groove on the two sides adjacent to the hinge connection surface, and the sleeve B has a central threaded groove on the two sides adjacent to the hinge connection surface.

[0007] As a preferred technical solution of this utility model, it includes: a locking bolt, wherein the locking bolt is threadedly installed in the threaded groove of the sleeve A, and the locking bolt is threadedly installed in the threaded groove of the sleeve B.

[0008] Compared with existing technologies, this utility model provides a labor-saving tool for deep well drilling slips, which has the following advantages: In use, first, the slip control claws grip the slip to be lifted or lowered, and tighten the fixing nut A. Then, rotate the operating rod up and down to the appropriate position. At this time, the connecting rod is in the corresponding position through the sliding of sleeve A and sleeve B. Tighten the locking bolts on the two sleeves, and the worker can easily lift and lower the slips from the wellhead by holding the handle and operating it remotely. The application of this deep well slip labor-saving tool effectively saves the physical strength of workers, reduces the number of personnel working at the wellhead, improves work efficiency, and reduces personnel safety risks.
