Abstract
Description
Technical Field
[0001] This utility model relates to the field of handling tools, and in particular to an auxiliary tool for short-distance handling of drill pipes. Background Technology
[0002] A drill pipe is a threaded steel tube used to connect the drilling rig's surface equipment to the drilling equipment or bottom hole assembly located at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and, together with the drill bit, raise, lower, or rotate the bottom hole assembly. Drill pipes must be able to withstand enormous internal and external pressures, torsion, bending, and vibration.
[0003] During use, drill rods need to be transported over short distances. Currently, when transporting drill rods over short distances, the main method is to lift the drill rod by manually supporting both ends or by inserting a pry bar or other transport aids into the drill rod. However, the surfaces of existing transport aids are relatively smooth, requiring a large amount of external force to transport the drill rod, making it laborious and inconvenient to use. Furthermore, the smooth surfaces of these tools have low friction, making the drill rod prone to falling off and potentially injuring workers. Utility Model Content
[0004] The purpose of this application is to provide an auxiliary tool for short-distance transport of drill pipes to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: a short-distance drilling pipe handling auxiliary tool, comprising a pry bar and a control rod, both of which are cylindrical and adapted to each other, both made of alloy material, and connecting components provided on the outer walls of adjacent sides of the pry bar and control rod, the connecting components being adapted to the pry bar and control rod respectively, a handle welded to the outer wall of the control rod, the handle being arc-shaped and adapted to the control rod, the outer wall of the handle being covered with an anti-slip sleeve adapted to it, the anti-slip sleeve being adapted to the handle, and anti-slip points evenly distributed on the bottom outer wall of the anti-slip sleeve, both the anti-slip sleeve and the anti-slip points being made of rubber material.
[0006] Preferably, the connecting assembly includes a connecting plate, which is circular and is adapted to the pry bar and the control bar respectively. Threaded rods are provided on both outer walls of the connecting plate.
[0007] Preferably, the length of the threaded rod is less than the length of the pry bar and the control rod, and threaded holes are provided on the outer walls of adjacent sides of the pry bar and the control rod, and the threaded holes are adapted to the threaded rod.
[0008] Preferably, the outer wall of the pry bar is provided with a wear-resistant pad, and the outer wall of the control rod is provided with a protective pad. The wear-resistant pad is adapted to the pry bar, and the protective pad is adapted to the control rod. The inner and outer diameters of the wear-resistant pad and the protective pad are the same.
[0009] Preferably, the outer wall of the pry bar is provided with equidistant limiting rings, which are adapted to the pry bar.
[0010] Preferably, the bottom outer wall of the pry bar has a mounting hole, and a support block is mounted on the inner wall of the mounting hole by means of a thread, the support block being adapted to the pry bar.
[0011] In summary, the technical effects and advantages of this utility model are as follows:
[0012] 1. In this utility model, the pry bar and control rod are connected by a connecting component to complete the assembly of the device. When in use, hold the handle, insert the pry bar into both ends of the drill rod, and hold the handle to lift the drill rod. The handle facilitates control of the control rod and makes it easier to apply force, making the drill rod easier to move. The anti-slip sleeve on the outer wall of the handle and the anti-slip points on the bottom of the anti-slip sleeve increase friction, preventing the tool from slipping during use. At the same time, the anti-slip sleeve protects the palm and facilitates tool use. The pry bar and control rod are connected by a threaded rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] refer to Figure 1-4 The illustrated drill pipe short-distance transport auxiliary tool includes a pry bar 1 and a control rod 2. Both the pry bar 1 and the control rod 2 are cylindrical and are fitted together. Both the pry bar 1 and the control rod 2 are made of alloy. Connecting components are provided on the outer walls of adjacent sides of the pry bar 1 and the control rod 2, respectively. A handle 3 is welded to the outer wall of the control rod 2. The handle 3 is arc-shaped and fitted to the control rod 2. The outer wall of the handle 3 is covered with a fitted anti-slip sleeve 4. The anti-slip sleeve 4 is adapted to the grip 3. The bottom outer wall of the anti-slip sleeve 4 is provided with anti-slip points 5 distributed at equal intervals. Both the anti-slip sleeve 4 and the anti-slip points 5 are made of rubber. The connecting component includes a connecting plate 6, which is circular. The connecting plate 6 is adapted to the pry bar 1 and the control rod 2 respectively. Threaded rods 7 are provided on both sides of the outer wall of the connecting plate 6. The length of the threaded rods 7 is less than the length of the pry bar 1 and the control rod 2. Threaded holes 8 are opened on the adjacent outer walls of the pry bar 1 and the control rod 2. The threaded holes 8 are adapted to the threaded rods 7.
[0023] With the above structure, the pry bar 1 and control rod 2 are connected by a connecting component to complete the assembly of the device. When in use, hold the handle 3, insert the pry bar 1 into both ends of the drill rod, and hold the handle 3 to lift the drill rod. The handle 3 facilitates control of the control rod 2 and makes it easier to apply force, making the drill rod easier to move. The anti-slip sleeve 4 on the outer wall of the handle 3 and the anti-slip point 5 at the bottom of the anti-slip sleeve 4 increase friction, preventing the tool from slipping during use. At the same time, the anti-slip sleeve 4 protects the palm and facilitates tool use. The pry bar 1 and control rod 2 are connected by a threaded rod 7. When the pry bar 1 or control rod 2 is damaged, only the damaged part needs to be replaced, without replacing the entire tool, making it more convenient to use.
[0024] Example 2
[0025] like Figure 3As shown, the outer wall of the pry bar 1 is provided with a wear-resistant pad 9, and the outer wall of the control rod 2 is provided with a protective pad 10. The wear-resistant pad 9 is compatible with the pry bar 1, and the protective pad 10 is compatible with the control rod 2. The inner and outer diameters of the wear-resistant pad 9 and the protective pad 10 are the same. The wear-resistant pad 9 protects the pry bar 1 and prevents damage to the pry bar 1. The protective pad 10 covers the control rod 2, protecting the control rod 2 and the user at the same time.
[0026] like Figure 2 As shown, the outer wall of the pry bar 1 is provided with equidistant limiting rings 11. The limiting rings 11 are adapted to the pry bar 1. The limiting rings 11 improve the wear resistance of the surface of the pry bar 1. When passing through the drill rod, the limiting rings 11 make it easy to fix the drill rod. When moving the drill rod, the pry bar 1 is not easy to slip, making it more stable and more convenient to use.
[0027] like Figure 2 As shown, the bottom outer wall of the pry bar 1 has an installation hole, and a support block 12 is installed on the inner wall of the installation hole by means of a thread. The support block 12 is adapted to the pry bar 1, and the support block 12 and the pry bar 1 cooperate with each other. When moving the drill rod, the support block 12 is connected to the pry bar 1, and the support block 12 is used as a fulcrum to make it easier to pry up the drill rod, making it more convenient to use.
[0028] The working principle of this practical application is as follows:
[0029] The pry bar 1 and control rod 2 are connected by a connecting component to complete the assembly of the device. When in use, hold the handle 3, insert the pry bar 1 into both ends of the drill rod, and hold the handle 3 to lift the drill rod. The handle 3 facilitates control of the control rod 2 and makes it easier to apply force, making it easier to move the drill rod. The anti-slip sleeve 4 on the outer wall of the handle 3 and the anti-slip point 5 at the bottom of the anti-slip sleeve 4 increase friction, preventing the tool from slipping during use. At the same time, the anti-slip sleeve 4 protects the palm and facilitates the use of the tool. The pry bar 1 and control rod 2 are connected by a threaded rod 7. When the pry bar 1 or control rod 2 is damaged, only the damaged part needs to be replaced, without replacing the entire tool, making it more convenient to use.
[0030] Wear-resistant pad 9 protects pry bar 1 from damage. Protective pad 10 covers control rod 2, protecting both control rod 2 and the user. When passing through drill rod, limit ring 11 helps to fix the drill rod. When moving drill rod, pry bar 1 is less likely to slip, making it more stable and easier to use. When moving drill rod, support block 12 is connected to pry bar 1, and support block 12 is used as a fulcrum to make it easier to pry up the drill rod, making it more convenient to use.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
