Description

Technical Field

[0001] The invention relates to the technical field of drill rod cleaning, in particular to a thread wiping device. Background Art

[0002] Oil is the lifeblood of industry. Many things used in human daily life come from oil and have become necessities. Every well drilled by each drilling team is drilled with a drill bit connected by a series of drill pipes. Therefore, drill pipes are of great importance in drilling. In order to ensure the quality of the drill pipe connection, the production unit will apply anti-corrosion grease to the threads at both ends of each drill pipe before leaving the factory, and then cover it with a plastic protective cover. However, the protective cover needs to be removed during drilling and the anti-corrosion grease needs to be removed.

[0003] The technology currently used is a cleaning method. After a large number of connecting rods arrive at the drilling area, workers clean them one by one with a solution. This method is not only inefficient, but also makes it easy for workers' hands to come into contact with the cleaning fluid, causing damage to their skin. In the cold winter and hot summer, the workers' operating environment is extremely poor. Therefore, a method for solving the grease problem is needed to improve efficiency and avoid damage to the human body. To this end, the present invention provides a thread wiping device.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-4The present invention provides a technical solution for a thread wiping device: a thread wiping device, comprising a handheld electric drill gun 1 and a battery holder 2 connected to the bottom of the handheld electric drill gun 1. The battery holder 2 can be configured with multiple batteries, which is convenient for replacement and improves battery life. The power output end of the handheld electric drill gun 1 is connected to an adjustment mechanism 3. The adjustment mechanism 3 is connected to three connecting members 4 in a triangular shape. The connecting member 4 is an L-shaped structure. One end of each connecting member 4 is fixedly connected to a fixed block 5. Three limiting slide rods 52 slide through the fixed block 5. One end of the three limiting slide rods 52 is commonly connected to a connecting block 51, and the other end of the three limiting slide rods 52 is connected to a baffle. The fixed block 5 and the connecting block 51 are fixed to each other. A spring 53 is sleeved on a limiting slide rod 52 located in the middle, and plywood 54 is symmetrically installed on both sides of the connecting block 51. The two plywood 54 are fixed to the two sides of the connecting block 51 by bolts. The three limiting slide rods 52 are fixedly connected to the connecting block 51 and are slidably connected to the fixed block 5. In the process of wiping the drill pipe thread with multiple layers of oil-absorbing paper 6, the connecting block 51 is slidably connected to the fixed block 5 through the limiting slide rod 52. Under the expansion and contraction force of the spring 53, the multiple layers of oil-absorbing paper 6 have a certain degree of adaptability when wiping the drill pipe thread, so that the multiple layers of oil-absorbing paper 6 can better fit the drill pipe thread, thereby further improving the wiping effect.

[0026] like Figure 5 As shown, the connecting block 51 is fixed with multiple layers of oil-absorbing paper 6 by two clamping plates 54. The multiple layers of oil-absorbing paper 6 are made of multiple layers of highly oil-absorbent material, and the surface of each layer of oil-absorbing paper is treated with a concave-convex shape. The thickness of each layer is 0.4-0.6 mm. The multiple layers of oil-absorbing paper 6 are fixed to the connecting block 51 by the clamping plates 54. After use, the bolts can be removed, and after replacement, the clamping plates 54 can be used to clamp and fix them.

[0027] like Figure 6 and 7 As shown, the adjustment mechanism 3 includes a connecting shaft 31 installed at the power output end of the handheld electric drill gun 1, and a round pedestal seat 32 is fixed to the other end of the connecting shaft 31. The outer side of the round pedestal seat 32 is rotatably connected to the rotating seat 33, and a limited seat 34 is installed on the upper end of the round pedestal seat 32. A positioning hole 35 is provided on the upper surface of the limiting seat 34. A threaded hole is provided on the upper surface of the round pedestal seat 32 corresponding to the positioning hole 35. The limiting seat 34 is screwed into the threaded hole on the surface of the round pedestal seat 32 through the positioning hole 35 by a bolt. The limiting seat 34 is fixed to the top of the round pedestal seat 32 by bolts, and the rotating seat 33 is rotatably set on the outside of the round pedestal seat 32, and according to Figure 6 and 8 As shown, the middle parts of the rotating seat and the limiting seat 34 are both hollow and through-designed, in order to provide space for the connector 4 to contract and expand.

[0028] The surface of the limit seat 34 is provided with an expansion slot 36 corresponding to one end of each connecting member 4, and the inner side wall of each expansion slot 36 symmetrically protrudes a limit slider 37. A slide 41 adapted to the expansion slot 36 is fixed to the bottom of one end of the connecting member 4, and limiting slots 42 adapted to the limiting slider 37 are provided on both sides of the slide 41. The slide 41 slides in the expansion slot 36, and the limiting slider 37 slides in the limiting slot 42. When the limiting channel at the bottom of the slide 41 slides toward its center on the spiral strip 38, the slide 41 slides toward the center of the limit seat 34 in the expansion slot 36. At the same time, the sliding limit of the limiting slider 37 and the limiting slot 42 improves the stability of the slide 41 when sliding. When the limiting channel at the bottom of the slide 41 slides toward its outer ring on the spiral strip 38, the slide 41 moves toward the outer ring of the limit seat 34 in the expansion slot 36.

[0029] A plurality of sliding blocks 43 are also distributed at the bottom of the slide 41, and a limited channel is formed between every two sliding blocks 43. A spiral strip 38 is fixed to the upper surface of the rotating seat 33, and the sliding block 43 slides on the spiral strip 38 through the limited channel. The spiral strip 38 at the top of the rotating seat 33 is located in the space at the bottom of the limited seat 34. When the slide 41 contracts or expands on the limited seat 34, the limited channel formed between the sliding blocks 43 slides on the spiral strip 38, thereby performing a spiral slide along the spiral strip 38. When the spiral strip 38 is rotated, the sliding block 43 slides on the spiral strip 38. When the center of the strip 38 slides, the three slides 41 move closer to each other, which can drive the three multi-layer oil-absorbing papers 6 to gather toward the center point (that is, closer to the drill rod thread), thereby reducing the distance between the three multi-layer oil-absorbing papers 6 to adapt to the wiping operation of small-sized drill rod threads. Conversely, when moving along the spiral strip 38 toward its outer circle, the three slides 41 expand outward from the center of the spiral strip 38, thereby moving the three multi-layer oil-absorbing papers 6 away from each other, thereby expanding the distance between the three multi-layer oil-absorbing papers 6 to adapt to the wiping operation of large-sized drill rod threads.

[0030] The working principle of the present invention is as follows: when working, the spacing between the three connecting members 4, that is, the spacing between the three multi-layer oil-absorbing papers 6, is adjusted through the adjustment mechanism 3 according to the diameter of the drill rod. During adjustment, the staff member holds the rotating seat 33 with one hand and turns on the switch of the handheld electric drill gun 1 with the other hand to control the handheld electric drill gun 1 to flip, so that the handheld electric drill gun 1 drives the limit seat 34 to rotate in the opposite direction through the connecting shaft 31, thereby driving the connecting member 4 to rotate in the opposite direction. When the connecting member 4 rotates in the opposite direction, the limiting channel at the bottom of the slide seat 41 slides toward its center along the spiral strip 38, thereby reducing the spacing between the three multi-layer oil-absorbing papers 6 to adapt to the wiping operation of the small-sized drill rod thread. Conversely, controlling the handheld electric drill gun 1 to rotate forward will expand the spacing between the three multi-layer oil-absorbing papers 6 to adapt to the wiping operation of the large-sized drill rod thread. After the adjustment is completed, the staff member releases the hand holding the rotating seat 33.

[0031] After the multi-layer oil-absorbing paper 6 is attached to the drill rod thread, the switch of the handheld electric drill gun 1 is used to control its reverse rotation, so that it drives the three connecting parts 4 to rotate synchronously through the adjustment mechanism 3. As a result, the three multi-layer oil-absorbing papers 6 are synchronously driven to quickly wipe the grease on the drill rod thread. The wiping is counterclockwise, and can be wiped from the inner end to the outer end of the drill rod thread. In addition, during the wiping process, the multi-layer oil-absorbing paper 6 can be adaptively adjusted by the action of the spring 53, so that the drill rod thread can be better wiped, thereby improving the speed of wiping and the cleaning efficiency.

[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
