Description

Technical Field

[0001] This utility model relates to the field of nut disassembly and assembly technology, and in particular to a locking nut installation tool. Background Technology

[0002] Oilfield centralizers, also known as stabilizers, are devices that ensure the quality of drilling and cementing. They are tools used to stabilize downhole drilling tools and prevent deviation. Connected to the drill string, they are used to stabilize the drilling direction and are important tools in oil, gas, and geological exploration drilling projects to prevent well deviation changes.

[0003] like Figure 1 and Figure 2 In the oil centralizer, the wire harness assembly 101 is generally installed inside a cylindrical housing 1, completely recessed therein, and then fixed by a locking nut 103, which is also completely located inside the cylindrical housing 1.

[0004] When installing the wire harness assembly 101, or when the oil stabilizer needs to be disassembled for maintenance after long-term use, the locking nut 103 that secures the wire harness assembly 101 is completely located inside the cylindrical housing 1, and cannot be disassembled with a regular wrench. Special tools are required for installation or disassembly.

[0005] Therefore, it is essential to design a specialized installation tool for installing or removing the locking nut 103, which is completely inside the cylindrical housing 1. Utility Model Content

[0006] The purpose of this utility model is to solve the technical problem of installing or removing the locking nut 103 that is completely inside the cylindrical shell 1 in the prior art, and to propose a locking nut installation tool.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A locking nut installation tool includes an insertion rod, one end of which is fixedly connected to a locking block; the end of the insertion rod away from the locking block is provided with a driving part.

[0009] Preferably, the number of the snap-fit ​​blocks is 2-4.

[0010] Preferably, the number of the snap-fit ​​blocks is four.

[0011] Preferably, the snap-fit ​​block and the insertion rod are integrally formed.

[0012] Preferably, the side wall of the insertion rod is provided with an inner groove, which extends to one end of the insertion rod located on the snap-fit ​​block.

[0013] Preferably, the driving part is a driving head; the cross-section of the driving head is polygonal, and the driving head is fixedly connected to the end of the insertion rod away from the snap-fit ​​block.

[0014] Preferably, the drive head and the insertion rod are integrally formed.

[0015] Preferably, the driving part is a through hole, which is located on the insertion rod and extends horizontally through the insertion rod.

[0016] Compared with the prior art, the present invention provides a locking nut installation tool, which has the following advantages:

[0017] This locking nut installation tool, when installing or removing the wire harness assembly, inserts the end of the insertion rod with the snap-fit ​​block into the cylindrical housing, so that the snap-fit ​​block engages with the notch, and then drives the insertion rod to rotate through the drive unit, which in turn drives the locking nut to rotate relative to the cylindrical housing, thereby achieving the purpose of installing or removing the locking nut.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1:

[0028] like Figure 1 and Figure 2 In the oil centralizer, the wire harness assembly 101 is installed inside the cylindrical housing 1, completely recessed therein, and then tightened and fixed by the locking nut 103. The locking nut 103 is threadedly connected inside the cylindrical housing 1 and is also completely located inside the cylindrical housing 1. The wire harness 102 of the wire harness assembly 101 extends outward from both ends of the cylindrical housing 1 for connection with other equipment.

[0029] The inner wall of the cylindrical shell 1 is provided with internal threads, and the outer wall of the locking nut 103 is provided with external threads, and the two can be connected by threads.

[0030] The locking nut 103 is ring-shaped. Generally, for installation and disassembly, the upper surface of the locking nut 103 is provided with notches 104, and the number of notches 104 is generally 2-4.

[0031] like Figures 1-6 A locking nut installation tool includes an insertion rod 2, which can be inserted into a cylindrical housing 1. One end of the insertion rod 2 is fixedly connected to a locking block 201. The number of locking blocks 201 is 2-4, and in this case, 4 are preferred. It should be noted that the number of locking blocks 201 corresponds to the number of notches 104, and the two are equal. In actual work, there are generally 4 notches 104. Therefore, in this case, the number of locking blocks 201 is also set to 4.

[0032] The width of the snap-fit ​​block 201 is less than or equal to the width of the notch 104, ensuring that the snap-fit ​​block 201 can snap into the notch 104.

[0033] The insertion rod 2 has a drive unit at the end away from the locking block 201, which is used to drive the insertion rod 2 to rotate.

[0034] When installing or removing the wire harness assembly 101, the end of the insertion rod 2 with the snap-fit ​​block 201 is inserted into the cylindrical housing 1, so that the snap-fit ​​block 201 engages with the notch 104. Then, the insertion rod 2 is driven to rotate by the drive unit, which in turn drives the locking nut 103 to rotate relative to the cylindrical housing 1, thereby achieving the purpose of installing or removing the locking nut 103.

[0035] When installing the wire harness assembly 101, the wire harness assembly 101 is tightened by rotating the locking nut 103.

[0036] When disassembling the wire harness assembly 101, remove the locking nut 103 by rotating it in the opposite direction, and then disassemble the wire harness assembly 101.

[0037] The snap-fit ​​block 201 and the insertion rod 2 are integrally formed, which improves the strength of the locking nut installation tool itself.

[0038] like Figures 3-6 The side wall of the insertion rod 2 is provided with an inner groove 202, which extends to one end of the insertion rod 2 located at the snap block 201.

[0039] The inner groove 202 extends to one end of the insertion rod 2 located on the snap block 201, meaning that the inner groove 202 is in a fully open state at the end near the snap block 201.

[0040] When installing or removing the wire harness assembly 101, the wire harness 102 located inside the cylindrical housing 1 of the wire harness assembly 101 is placed in the inner groove 202 during the process of rotating the locking nut 103 driven by the insertion rod 2. Then, the insertion rod 2 is rotated to avoid interference between the insertion rod 2 and the wire harness 102.

[0041] As the insertion rod 2 rotates, the wire harness 102 will also rotate and wrap around the insertion rod 2. At this time, after the insertion rod 2 rotates a few times, such as 2-4 times, the rotation can be temporarily stopped, the wire harness 102 wrapped around the insertion rod 2 can be released, and then the rotation can continue until the locking nut 103 is fully installed, or the locking nut 103 can be removed.

[0042] The insert rod 2 and the snap-fit ​​block 201 are both made of hard metal, such as steel.

[0043] Example 2:

[0044] This embodiment is basically the same as Embodiment 1, but based on Embodiment 1, a driving unit is proposed.

[0045] like Figure 5The driving part is the driving head 203; the cross-section of the driving head 203 is polygonal, generally hexagonal or octagonal. The driving head 203 is fixedly connected to the end of the insertion rod 2 away from the snap block 201. The driving head 203 and the insertion rod 2 are integrally formed to improve stability.

[0046] When it is necessary to rotate the insertion rod 2, use an existing wrench to engage with the drive head 203, and drive the insertion rod 2 to rotate through the wrench.

[0047] The drive head 203 is made of the same material as the insertion rod 2.

[0048] Example 3:

[0049] This embodiment is basically the same as Embodiment 1, but based on Embodiment 1, a second type of driving unit is proposed.

[0050] like Figure 5 The driving part is a through hole 3, which is located on the insertion rod 2 and extends horizontally through the insertion rod 2.

[0051] Prepare a rod in advance, made of hard materials such as metal or plastic, with a diameter smaller than the inner diameter of the through hole 3, so that the rod can pass through the through hole 3.

[0052] When it is necessary to rotate the insertion rod 2, insert the rod through the through hole 3, and then rotate the rod with both hands to drive the insertion rod 2 to rotate.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
