Description

Technical Field

[0001] This utility model relates to the field of special bolt technology, specifically a special tool for disassembling and assembling special bolts. Background Technology

[0002] Special bolts are fasteners designed and manufactured to meet specific working conditions. Compared with ordinary standard bolts, they differ significantly in materials, structure, performance, or application. These bolts are usually made of special materials such as high-strength alloy steel, stainless steel, and titanium alloy, and have characteristics such as high temperature resistance, corrosion resistance, and fatigue resistance. The structural design of special bolts is often more complex and may include irregular heads, special threads, or anti-loosening structures to cope with vibration, impact, or sealing requirements in extreme environments.

[0003] In the production of urea and other fertilizers, equipment is often exposed to high temperature, high pressure and highly corrosive media (such as ammonia, nitric acid, urea solution, etc.), which places extremely high demands on the connectors. Ordinary bolts are prone to corrosion, loosening or even breakage in this environment, affecting the sealing and operational stability of the equipment. Therefore, special bolts are widely used in fertilizer production equipment due to their excellent corrosion resistance, high temperature resistance and stress corrosion cracking resistance.

[0004] When maintaining fertilizer production equipment that uses special bolts, it is necessary to disassemble and assemble these special bolts. Traditional tools (such as open-end wrenches and socket wrenches) lack adaptive adjustment functions, making it difficult to match the complex geometry of special bolts. This can easily lead to slippage or damage to the bolts during disassembly and assembly. Therefore, a special tool for disassembling and assembling special bolts is proposed to address the above problems. Utility Model Content

[0027] Please see Figures 1-8 This utility model provides a technical solution:

[0028] A special tool for disassembling and assembling special bolts includes a main body 1, a disassembly and assembly component 2 at the bottom of the main body 1, and a connecting component 3 at the top of the main body 1. The disassembly and assembly component 2 includes a disassembly and assembly base 21, a disassembly and assembly groove 22 is formed at the center of the bottom of the disassembly and assembly base 21, and a plurality of adjusting bolts 23 are arranged at equal intervals on the side wall of the disassembly and assembly groove 22. The adjusting bolts 23 penetrate through the side wall of the disassembly and assembly groove 22 and extend into the disassembly and assembly groove 22, and the adjusting bolts 23 are threadedly connected to the side wall of the disassembly and assembly groove 22. A fastening structure 24 is provided at one end of the adjusting bolts 23 extending into the disassembly and assembly groove 22. The bottom of the main body 1 is fixedly welded to the top of the disassembly and assembly component 2, and the top of the main body 1 is fixedly welded to the bottom of the connecting component 3.

[0029] As a further implementation of this solution, the fastening structure 24 includes a fastening clamp 241 fixedly connected to one end of the adjusting bolt 23 extending into the disassembly groove 22. The fastening clamp 241 is trapezoidal in shape, and the side of the fastening clamp 241 away from the inner wall of the disassembly groove 22 is open. A fastening pad 242 is provided inside the fastening clamp 241. The fastening pad 242 is arc-shaped and concave inward toward the fastening clamp 241. Both ends of the fastening pad 242 are fixed to the inner wall of the fastening clamp 241. The fastening pad 242 is fixedly connected to a number of rubber clamping blocks 243 on the side away from the fastening plate 241. The fastening plate 241 and the fastening pad 242 are symmetrically provided with spring grooves 244 on the sides close to each other. Fastening springs 245 are fixedly connected in the spring grooves 244 on the fastening plate 241 and the fastening pad 242. The above configuration can be adapted to the complex geometry of special bolts through adaptive adjustment, so that it is not easy to slip or damage the bolts when disassembling or assembling special bolts.

[0030] As a further implementation of this solution, the connecting component 3 includes a connecting seat 31. A connecting interface 32 is provided at the top center of the connecting seat 31. Receiving grooves 33 are symmetrically provided on both sides of the top of the connecting seat 31. A connecting support rod 34 is movably inserted into the receiving groove 33. A reinforcing half-sleeve 35 is fixedly connected to the top of the connecting support rod 34. A reinforcing clamping groove 36 matching the specifications of the connecting interface 32 is provided on the inner side of the reinforcing half-sleeve 35. The two reinforcing half-sleeves 35 are connected by a threaded mounting bolt. A first positioning hole 37 is provided at the bottom of the outer side wall of the connecting support rod 34. Two pairs of second positioning holes 38 penetrating the receiving grooves 33 are symmetrically provided on both sides of the connecting seat 31. Positioning pins 39 are inserted into the second positioning holes 38 and the first positioning holes 37. The above configuration allows the main body 1 to be externally connected to a rotating handle or power tool, thereby making it more convenient to disassemble or install special bolts and enhancing the connection stability between the main body 1 and the rotating handle or power tool.

[0031] Workflow: When disassembling or installing special bolts, first place the main body 1 at the special bolt and fix it to the head of the special bolt using the disassembly and assembly component 2. The disassembly and assembly component 2 can match the complex geometry of the special bolt through an adaptive adjustment function, thus preventing slippage or damage to the bolt during disassembly and installation. For fixing, first fit the disassembly and assembly slot 22 at the bottom of the disassembly and assembly base 21 onto the outside of the special bolt head, and then rotate the adjusting bolt 23. The adjusting bolt 23 will drive the fastening clamp 241 in the fastening structure 24 to move towards the head of the special bolt until the fastening clamp 241 is in close contact with the head of the special bolt. The adjustment is then completed by rotating the adjusting bolt. The rotation adjustment of bolt 23 allows the fastening structure 24 to adapt to special bolt heads of different specifications or shapes. While the fastening clamp 241 is in close contact with the special bolt head, the fastening spring 245 in the spring groove 244 will drive the fastening pad 242 to move towards the special bolt head through its own rebound force. The rubber clamp 243 on the fastening pad 242 will then contact the special bolt head, increasing the friction between the fastening clamp 241 and the special bolt head. In addition, the rubber clamp 243 can buffer the clamping force to a certain extent through its own rubber properties, preventing damage to the special bolt head due to excessive clamping force.

[0032] The connecting interface 32 at the top of the connecting seat 31 in the connecting assembly 3 allows the main body 1 to connect to a rotary handle or power tool after the main body 1 is fitted with a special bolt via the disassembly and assembly assembly 2. This makes it easier to disassemble or install the special bolt. When connecting a rotary handle or power tool, first, pass the end of the rotary handle or power tool through the reinforcing groove 36 through the two reinforcing half-sleeves 35 and insert it into the connecting interface 32 at the top of the connecting seat 31. Then, pull out the positioning pin 39 in the first positioning hole 37 and the second positioning hole 38 located below, and pull the connecting support rod 34 upward from the receiving groove 33 until it reaches the first positioning hole 37. Corresponding to the position of the second positioning hole 38 located above, the positioning pin 39 is then inserted into the second positioning hole 38 and the first positioning hole 37 located above to limit the connecting support rod 34. At this time, the upward-moving reinforcing half-sleeve 35 will clamp the end of the rotary handle or power tool through the reinforcing clamp groove 36. Finally, the two reinforcing half-sleeves 35 are threaded together by the mounting bolt. This can enhance the connection stability between the main body 1 and the rotary handle or power tool, thereby preventing the rotary handle or power tool from falling off due to poor connection stability between the main body 1 and the rotary handle or power tool during the disassembly and assembly of special bolts.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
