Description

Technical Field

[0001] This utility model relates to the field of maintenance auxiliary tools, and in particular to a vibration probe disassembly and assembly tool. Background Technology

[0002] In the oil and gas industry, natural gas compressor units are core equipment. To ensure the pressurization and transportation needs of pipeline trunk lines and to ensure the high precision and high reliability of the equipment, it is necessary to monitor the vibration status of key rotating parts such as the main shaft of the unit in real time. Vibration probes are usually used to monitor the operation of the compressor unit.

[0003] A vibration probe typically consists of a body and a signal cable connected to it. A fastening nut is attached to the outer periphery of the body, and an adjusting bolt is located at the end where the body connects to the signal cable. During debugging, it is usually necessary to adjust the vibration probe's gap and tighten the body. However, existing disassembly and assembly tools typically involve disassembling and assembling the probe separately, performing the gap adjustment and body tightening operations step by step. However, disassembling and assembling the signal cable separately increases the possibility of equipment damage. For overall debugging, since the vibration probe is usually installed inside a hole, tool disassembly and assembly operations are limited, and improper operation may lead to broken signal cables and damage to the probe body.

[0004] Therefore, there is an urgent need for a vibration probe disassembly and assembly tool to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration probe disassembly and assembly tool to solve the technical problem that the vibration probe cannot be adjusted as a whole in the existing technology.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0036] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Specifically, the terms "first position" and "second position" refer to two different positions.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In the oil and gas industry, natural gas compressor units are core equipment, characterized by high flow rates, high pressure ratios, and high speeds. To ensure the pressurization and transmission needs of pipeline trunk lines and to guarantee high precision and reliability of the equipment, the design incorporates real-time dynamic monitoring of the vibration status of key rotating parts such as the unit's main shaft. This function transmits data from vibration probes to the control unit for display on the terminal, helping operators to promptly identify and prevent potential mechanical failures. During the disassembly, assembly, and maintenance of the compressor unit's vibration probes, it was discovered that the manufacturer had not provided the necessary specialized tools. Existing commonly used tools were insufficient for the specific needs of this situation, and the vibration probe gap adjustment and body locking functions could not be performed simultaneously during commissioning. This resulted in unstable equipment operation or commissioning failures, and in severe cases, equipment malfunctions.

[0040] Therefore, this utility model discloses a tool for disassembling and assembling a vibration probe. For example... Figures 1 to 3As shown, the vibration probe assembly / disassembly tool includes an outer wrench 1 and an inner wrench 2. The outer wrench 1 includes a first wrench head 11 and a first wrench handle 12. One end of the first wrench head 11 is used to adjust the fastening nut of the vibration probe, and the other end is connected to the first wrench handle 12. The inner wrench 2 includes a second wrench head 21 and a second wrench handle 22. One end of the second wrench head 21 is used to adjust the adjusting bolt of the vibration probe, and the other end is connected to the second wrench handle 22. The second wrench head 21 is fitted inside the first wrench head 11. Both the first wrench head 11 and the second wrench head 21 have a first groove 3 along the axial direction, through which the vibration probe cable can pass.

[0041] It is understood that the vibration probe disassembly and assembly tool proposed in this utility model has through holes extending axially on both the first wrench head 11 and the second wrench head 21, and both the first wrench head 11 and the second wrench head 21 have first grooves 3 extending axially. The first wrench head 11 on the outer wrench 1 cooperates with the fastening nut of the vibration probe, and the second wrench head 21 on the inner wrench 2 cooperates with the adjusting bolt of the vibration probe. The second wrench head 21 is fitted inside the first wrench head 11, so that the outer wrench 1 can directly pass through the cable on the vibration probe and be fitted onto the fastening nut of the vibration probe. At the same time, the inner wrench 2 can also directly pass through the cable on the vibration probe and be fitted onto the adjusting bolt of the vibration probe. This avoids the need for existing disassembly and assembly tools to perform the fastening and gap adjustment of the vibration probe in separate steps, which increases the possibility of cable damage.

[0042] When using the inner wrench 2 and the outer wrench 1, first adjust the gap of the vibration probe using the inner wrench 2, then hold the inner wrench 2 to fix one end of the vibration probe connecting cable to ensure that the gap of the vibration probe does not change. At the same time, rotate the outer wrench 1 to tighten the vibration probe. This process of adjusting and tightening the vibration probe gap improves the efficiency of disassembly and assembly, and also avoids changes in the gap caused by connecting the cable or tightening the vibration probe with other tools after the gap adjustment is completed. This effectively improves the installation accuracy and the accuracy of subsequent monitoring data.

[0043] Furthermore, to facilitate the fitting of the second wrench head 21 within the first wrench head 11, in some embodiments, the inner diameter of the first wrench head 11 is larger than the outer diameter of the second wrench head 21. This arrangement improves the smoothness of fitting the second wrench head 21 within the first wrench head 11, thereby increasing the working efficiency of the vibration probe assembly / disassembly tool during use.

[0044] Furthermore, in some embodiments, such as Figure 2As shown, the first wrench head 11 includes a first sleeve 111 and a first connecting member 112. The first sleeve 111 has a first engaging portion for engaging with a fastening nut. One end of the first connecting member 112 is connected to the first sleeve 111, and the other end is connected to the first wrench handle 12. Specifically, as shown... Figure 2 As shown, in this embodiment, the first snap-fit ​​part is an internal hexagonal portion provided inside the first sleeve 111 that mates with the fastening nut of the vibration probe. The first snap-fit ​​part engages with the fastening nut, and the first connecting piece 112 can increase the length of the first wrench head 11, making it easier for the operator to tighten the vibration probe located in the hole. The operator can tighten or loosen the vibration probe by rotating the first wrench handle 12.

[0045] More specifically, in this embodiment, the length of the first sleeve 111 is 46mm, the outer diameter is 20mm, and the distance between opposite sides of the inner hexagon of the first sleeve 111 is 14mm.

[0046] Furthermore, in some embodiments, a second groove 1121 is provided axially on the first connector 112, and the opening of the second groove 1121 is larger than the first groove 3 of the first sleeve 111. By providing the second groove 1121, it is convenient for the operator to insert the second sleeve 211 into the first sleeve 111 after the first sleeve 111 is engaged with the fastening nut of the vibration probe, thereby improving work efficiency. Preferably, the opening of the second groove 1121 is larger than the outer diameter of the second sleeve 211.

[0047] Specifically, such as Figure 2 As shown, in this embodiment, the first connector 112 is also cylindrical, and the outer diameter of the first connector 112 is the same as the outer diameter of the first sleeve 111. This arrangement can improve the smoothness of the first wrench head 11 when it is inserted into the hole, making it easier for the first wrench head 11 to extend along the hole to the position where the vibration probe tightens the nut.

[0048] More specifically, the first connector 112 is a semi-cylinder with a diameter of 20 mm and a thickness of 2 mm.

[0049] Furthermore, in some embodiments, the second wrench head 21 includes a second sleeve 211 and a second connecting member 212. The second sleeve 211 is provided with a second locking portion for engaging with an adjusting bolt. One end of the second connecting member 212 is connected to the second sleeve 211, and the other end is connected to the second wrench handle 22.

[0050] Specifically, such as Figure 2As shown, in this embodiment, the second snap-fit ​​part is the inner four corner portion provided inside the second sleeve 211 that mates with the adjusting bolt of the vibration probe. The second snap-fit ​​part engages with the adjusting bolt, and the second connecting piece 212 can increase the length of the second wrench head 21, making it easier for the operator to adjust the vibration probe installed in the hole. The operator adjusts the gap between the vibration probe and the hole by rotating the second wrench handle 22, and after adjustment, the vibration probe is tightened by the second wrench handle 22.

[0051] More specifically, in this embodiment, the second sleeve 211 has a length of 16mm, an outer diameter of 13mm, and a distance of 8mm between opposite sides of the four inner corners of the second sleeve 211.

[0052] Furthermore, in some embodiments, the outer diameter of the second connector 212 is the same as the outer diameter of the second sleeve 211. It is understood that this arrangement improves the smoothness of insertion of the second wrench head 21 into the hole, facilitating its extension along the hole to the position of the vibration probe adjustment bolt. More specifically, the second connector 212 is a semi-cylinder with a diameter of 13 mm and a thickness of 2 mm.

[0053] Furthermore, in some embodiments, the first wrench head 11 is detachably connected to the first wrench handle 12. The second wrench head 21 is detachably connected to the second wrench handle 22. This arrangement allows for the assembly of first wrench heads 11 and handles of different sizes according to the usage requirements of different vibration probes, improving the applicability of the disassembly and assembly tools.

[0054] Furthermore, in this embodiment, as Figure 2 and Figure 3 As shown, the first wrench head 11 is perpendicularly connected to the first wrench handle 12; the second wrench head 21 is perpendicularly connected to the second wrench handle 22. It is understandable that this arrangement increases the length of the lever arm, making the use of the inner wrench 2 and the outer wrench 1 easier.

[0055] Furthermore, such as Figures 1 to 3 As shown, to avoid the hand gripping the first handle 12 and affecting the rotation of the second handle 22 when using the inner wrench 2 and the outer wrench 1, in some embodiments, the length of the first wrench head 11 is smaller than that of the second wrench head 21. Specifically, in this embodiment, the first connecting member 112 has an axial length of 150mm.

[0056] It is understandable that, in order to ensure the structural strength of the vibration probe disassembly and assembly tool, in some embodiments, the first sleeve 111 and the second sleeve 211 are made of carbon steel, the first connector 112 and the second connector 212 are made of stainless steel, and the first handle 12 and the second handle 22 are made of galvanized flat steel.

[0057] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
