Description

Technical Field

[0001] The utility model relates to the technical field of probe nut disassembly and assembly tools, and particularly relates to an assembly tool for a probe fixing nut of an air separation unit. Background Art

[0002] The probe fixing nut disassembly and assembly tool for an air separation unit is a special tool dedicated to disassembling and assembling the probe fixing nut in an air separation unit (air separation device). These probes are usually used to monitor key parameters during the operation of the air separation unit, such as temperature, pressure, etc.

[0003] 1. These tools are usually designed according to specific probes and fixing nuts to ensure compatibility with specific models of air separation units. The tools are usually made of high-strength and corrosion-resistant materials to adapt to the working environment of the air separation unit. Considering the convenience of on-site operation in the design, they usually have a simple operation interface or a user-friendly handle design.

[0004] 2. Wrench: A common type of tool, which can be an open-end wrench, a socket wrench or a box wrench, used to tighten or loosen the fixing nut. Torque wrench: Used to precisely control the tightening torque to avoid over-tightening or under-tightening. Special tool: For some specially designed probes and fixing nuts, specially designed tools may be required for disassembly and assembly.

[0005] 3. Positioning: First, determine the position of the probe and ensure that the tool is aligned with the fixing nut. Disassembly and assembly: Select the appropriate tool according to the type and size of the nut, and then tighten or loosen the nut in the correct direction. Torque control: When using a torque wrench, it is necessary to operate according to the torque value recommended by the manufacturer to ensure that the tightening degree of the nut meets the requirements.

[0006] 4. Correct tool selection: Ensure the use of tools that match the nut size to avoid damage to the nut due to inappropriate tools. Operation safety: During disassembly and assembly, appropriate personal protective equipment, such as gloves, goggles, etc., should be worn. Maintenance and servicing: Regularly check the wear condition of the tool to ensure it is in good condition.

[0007] The disassembly and assembly tool for the probe fixing nut of the air separation unit is an essential tool to ensure the normal operation and maintenance of the air separation unit. The correct selection and use of these tools are crucial for ensuring the installation accuracy of the probe and extending the service life of the equipment. In the coal chemical industry, blowers, compressors, and various steam turbine units are widely used. To ensure the high efficiency and safety of equipment operation, these units are equipped with a variety of displacement and vibration monitoring probes. However, due to the cables attached to the probes during the installation process, the fixing nuts of the probes are often located deep inside the machine body, which poses a great challenge to the tightening work because conventional tools are difficult to socket the probes and reach deep into the machine body for effective tightening. The probe fixing nuts are generally recessed in the equipment body, and due to space problems, general tools cannot be used. The probe itself has an extension cable, which affects the tightening process when tightening the fixing nut.

[0008] Therefore, there is an urgent need to design an assembly tool for the probe fixing nut of the air separation unit to solve the problems that the existing disassembly and assembly tools cannot reach the sunken probe nuts and the probe cables hinder rotation. Utility Model Content

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 - 3 shown, an assembly tool for the probe fixing nut of an air separation unit includes a sleeve 1, a socket head 2, a wire-passing opening 3, an auxiliary handle 4, and an inclined support beam 5. The sleeve 1 adopts a through cylindrical structure. One end of the sleeve 1 is fixedly connected to the socket head 2. The inner diameter model of the socket head 2 is adapted to the probe fixing nut. A vertically through wire-passing opening 3 is provided on the same side of the sleeve 1 and the socket head 2, and the cable of the probe passes through the wire-passing opening 3.

[0025] One end of the sleeve 1 is welded to the socket head 2, and the socket head 2 adopts a socket wrench with a diameter of 16 mm.

[0026] An auxiliary handle 4 is welded on the side of the sleeve 1 far from the socket head 2. The auxiliary handle 4 is perpendicularly connected to the outer wall of the sleeve 1, and the length of the auxiliary handle 4 is 200 mm.

[0027] On both sides of the auxiliary handle 4, the diagonal bracing beams 5 are fixedly welded, and the bottom of the diagonal bracing beams 5 is fixedly welded to the outer wall of the sleeve 1. The sleeve 1 is made of stainless steel pipe, the outer diameter of the sleeve 1 is 20 mm, and the length of the sleeve 1 is 200 mm.

[0028] The width of the wire passing opening 3 on the sleeve 1 and the plum blossom head 2 is 5 mm.

[0029] The manufacturing principle of the utility model: Using stainless steel pipe to make fastening tools including nut fastening part, extension sleeve, and torque arm. First, take a 200-mm DN20 thick-walled stainless steel pipe and a M16 plum blossom head 2, and fix the M16 plum blossom head 2 to the bottom end face of the stainless steel pipe by precise welding, aiming to enable the tool to effectively fasten the fixing nut at the probe. Then, weld a 200-mm solid iron rod to the other end of the stainless steel pipe to make it an important part of the torque arm. Finally, use a cutting machine to make an opening in the extension sleeve, allowing the cable to pass through the middle. This design ensures the convenient arrangement of the extension cable during fastening, saving time and effort.

[0030] 1. The fastening tool has a unique design. One end of it can reach into the recess of the unit to precisely fasten the fixing nut. The design of the torque arm (auxiliary handle 4) ensures the uniform and appropriate fastening force, effectively avoiding the problem that the fastening effect is affected by too large or too small force.

[0031] 2. This simple probe fastening tool has a clever design. The middle part is a hollow structure with an opening on the side. During fastening, the probe cable can pass through the hole in the middle, which not only solves the problem that the probe cable shuttles back and forth and has nowhere to be placed during fastening, but also ensures the smooth progress of the fastening process.
