Abstract
Description
Technical Field
[0001] This utility model relates to the field of disassembly and installation technology of electric shear valve pulsers, and in particular to a tool for disassembling and installing the external magnet of a shear valve pulser. Background Technology
[0002] In oil drilling, wireless measurement-while-drilling instruments are commonly used to measure directional wells, horizontal wells, extended reach wells, and branch wells, facilitating real-time understanding of downhole parameters. Among these, the shear valve pulser, which relies on fluctuations in drilling hydraulic pressure to transmit signals, is currently the most widely used and reliable method in drilling processes.
[0003] The external magnet is one of the core components that ensures the instrument can work properly. Its complex operating environment and frequent rotation cause its bearings to wear and jam, requiring regular replacement and maintenance.
[0004] Due to the special nature of its structure, the disassembly or installation of its external magnet is extremely difficult. It is necessary to fix the shear valve pulse generator housing before disassembling or installing the external magnet.
[0005] However, the existing tools for disassembling and installing the external magnet of the shear valve pulser are relatively complex in structure, making the operation cumbersome when fixing the shear valve pulser housing, which in turn greatly reduces the efficiency of disassembly and installation. Utility Model Content
[0006] The purpose of this utility model is to solve the technical problem in the prior art that the operation of fixing the housing of the shear valve pulser is cumbersome, which leads to a significant reduction in the efficiency of disassembly and installation. Therefore, this utility model proposes a tool for disassembling and installing the external magnet of the shear valve pulser.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A tool for disassembling and installing the external magnet of a shear valve pulser includes a clamping plate and a collar. The clamping plate is designed in two sets, and both sets of clamping plates are arc-shaped. The inner wall of both sets of clamping plates is provided with a clamping groove. The collar is fitted onto the outer wall of the two sets of clamping plates.
[0009] Preferably, the top of the inner wall of both sets of the card plates is provided with a chamfer.
[0010] Preferably, the two sets of card plates are truncated cone-shaped.
[0011] Preferably, the collar has a beveled edge that matches the outer wall of the card plate.
[0012] Compared with the prior art, this utility model provides a ° flipping mechanism for battery electrolyte filling, which has the following beneficial effects:
[0013] This tool for disassembling and installing the external magnet of the shear valve pulser uses two sets of clamping plates and a collar to quickly fix the housing of the shear valve pulser. It has a simple structure and is easy for operators to use, thereby improving the efficiency of disassembling and installing the external magnet of the shear valve pulser. Attached Figure Description

[0019] 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.
[0020] 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.
[0021] Example:
[0022] like Figures 1-4 A tool for disassembling and installing the external magnet of a shear valve pulser includes a clamping plate 1 and a collar 2. The clamping plate 1 is designed in two sets, both sets of clamping plates 1 are arc-shaped, and together they can form a rotating cylinder, which is hollow. The inner walls of both sets of clamping plates 1 are provided with a clamping groove 101, which matches the shape of the shear valve pulser housing.
[0023] The 2-ring is fitted onto the outer wall of the two sets of 1-plates.
[0024] When it is necessary to fix the housing during the disassembly or installation of the external magnet of the shear valve pulse generator, two sets of clamping plates 1 are clamped on the outer wall of the housing, and then the collar 2 is put on the two sets of clamping plates 1 for limiting and fixing the housing. Then, the external magnet is disassembled or installed on the worktable.
[0025] The shear valve pulse generator housing is quickly fixed by two sets of clamping plates 1 and collar 2. The structure is simple and easy for operators to operate, thereby improving the efficiency of disassembling and installing the external magnet of the shear valve pulse generator.
[0026] like Figure 1 and Figure 2 The top of the inner wall of the two sets of card plates 1 is provided with a chamfer 102.
[0027] When the shear valve pulse generator housing is fixed in the two sets of clamping plates 1, the chamfered edge 102 facilitates the disassembly and installation of the external magnet of the shear valve pulse generator, improving the operating space and convenience.
[0028] The two sets of card plates are truncated cones, smaller at the top and larger at the bottom, with an inclination angle of 5-10° to improve stability.
[0029] The collar 2 has a bevel 201 that matches the outer wall of the card plate 1, and the angle of the bevel 201 matches the shape of the frustum-shaped card plate 1.
[0030] The design of the inclined side 201 makes the collar 2 and the frustum-shaped clamping plate 1 more stably engaged, improving the fixing effect.
[0031] 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.
