Description

Technical Field

[0001] This utility model relates to the field of disassembly technology of threaded locking ring heat exchangers, specifically a tooling for disassembling bolts of threaded locking ring heat exchangers. Background Technology

[0002] Threaded locking ring heat exchangers are highly efficient heat exchange devices widely used in industries such as petroleum, chemical, and oil refining. They feature compact structure, high heat exchange efficiency, and good sealing performance, enabling stable operation under complex conditions such as high temperature, high pressure, and corrosive media.

[0003] Regular maintenance and repair of threaded locking ring heat exchangers are crucial for ensuring their safe and stable operation. Bolts, as vital components connecting various parts of the heat exchanger, need to be disassembled during maintenance. Only by successfully removing the bolts can the heat exchanger be opened to inspect, clean, and replace internal components such as tube bundles, tube sheets, and sealing surfaces. This allows for the timely detection and resolution of potential safety hazards, extending the service life of the heat exchanger.

[0004] For large threaded locking ring heat exchangers, the number of bolts is large, their size is large, and the installation torque is high, making manual disassembly time-consuming and labor-intensive. Moreover, manual operation makes it difficult to precisely control the torque, which can easily lead to situations where excessive torque damages the bolts or insufficient torque prevents successful disassembly.

[0005] In existing technologies, when disassembling the bolts of large threaded locking ring heat exchangers, the distribution of multiple bolts results in different heights and positions requiring disassembly, necessitating flexible adjustment of the disassembly tooling.

[0006] Therefore, we urgently need to provide a tooling for disassembling threaded locking ring heat exchanger bolts. Utility Model Content

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] In existing technologies for disassembling bolts on large threaded locking ring heat exchangers, the distributed installation of multiple bolts results in varying heights and positions requiring disassembly. Therefore, flexible adjustment of the disassembly fixtures is necessary. Please refer to [reference needed]. Figures 1-4The embodiment provides a bolt removal tool for a threaded locking ring heat exchanger, which can effectively improve the flexibility of the bolt removal process. The bolt removal tool for the threaded locking ring heat exchanger includes a moving carriage 1, an adjustment device is installed on the top of the moving carriage 1, a removal drive device is installed on the top of the adjustment device, and a clamping removal device is installed on the left side of the removal drive device.

[0028] The adjustment device includes a lifting structure and a horizontal adjustment structure, with the horizontal adjustment structure installed on top of the lifting structure. The horizontal adjustment structure includes an asynchronous motor 104, the output of which is connected to an adjusting component 105. A disassembly platform 106 is connected to the center of the outer surface of the adjusting component 105, and a limit block 107 is installed on the center of the bottom surface of the disassembly platform 106 near one end of the front and back sides. The lifting structure includes a hydraulic cylinder 101, the output of which is connected to a lifting platform 102, and a telescopic rod 103 is connected to the bottom surface of the lifting platform 102.

[0029] The bottom of the hydraulic cylinder 101 and the telescopic rod 103 are connected to the top surface of the mobile vehicle 1. The asynchronous motor 104 is detachably installed in the middle right side of the lifting platform 102. The outer surface of the middle part of the adjusting component 105 is slidably connected to the inner wall of the rectangular groove in the middle of the top surface of the lifting platform 102. The outer surface of the limiting block 107 is slidably connected to the inner wall of the convex groove in the top of the lifting platform 102.

[0030] By adjusting the device, the hydraulic cylinder 101 drives the lifting platform 102 to rise and fall, and the asynchronous motor 104 drives the adjusting component 105 to move the disassembly platform 106, thereby flexibly disassembling bolts in various positions.

[0031] The hydraulic cylinder 101 is activated to drive the lifting platform 102 to rise and fall. During the lifting process, the telescopic rod 103 ensures stability. The asynchronous motor 104 is activated to drive the adjusting component 105 for transmission. The output end of the asynchronous motor 104 drives the threaded rod to rotate. The outer surface of the threaded rod is threadedly connected to the moving block. The moving block is slidably connected to the inner wall of the moving groove on the top surface of the lifting platform 102, thereby driving the disassembly platform 106 to move. This facilitates the disassembly of bolts and allows for flexible adjustment of the position of the disassembly device during disassembly.

[0032] Example 2:

[0033] Based on Implementation 1, existing technologies also suffer from bolt adhesion due to high temperature, high pressure, and corrosion, leading to increased tightening force and difficulty in disassembly. Please refer to... Figures 1-4This embodiment provides a tooling for disassembling threaded locking ring heat exchanger bolts, which can effectively solve the problem of disassembling stuck bolts. The tooling includes a disassembly drive device comprising a rotary motor 201. A transmission component 202 is connected to the output end of the rotary motor 201. A rotating shaft 203 is installed inside the transmission component 202, and a rotating table 204 is connected to the left end of the rotating shaft 203. The rotary motor 201 is detachably mounted on the left side of the disassembly table 106 near the top, and the rotating shaft 203 is mounted on the left side of the disassembly table 106 via bearings in the middle.

[0034] The clamping and disassembly device includes an electric push rod 301, with a clamping rod 302 connected to the output end of the electric push rod 301. A clamping head 303 is fixedly installed on the left end of the clamping rod 302. A vibrator 304 is arranged between the two clamping rods 302, and a collection box 305 is provided at the bottom of the vibrator 304. The electric push rod 301 is installed in the middle of the front and back of the rotary table 204. The end of the clamping rod 302 away from the clamping head 303 is slidably connected to the inside of the clamping groove in the middle of the left side of the rotary table 204. The vibrator 304 is installed in the middle of the left side of the rotary table 204, and the collection box 305 is installed in the middle left end of the top surface of the lifting platform 102.

[0035] By setting up a disassembly drive device and a clamping disassembly device, the vibrator 304 is used to facilitate the loosening and disassembly of the stuck bolts, while the collection box 305 is used to facilitate the collection of the disassembled bolts.

[0036] When disassembling the bolt, the electric push rod 301 is activated to drive the clamping rod 302 and the clamping head 303 to clamp and lock the bolt. Then, the vibrator 304 is activated to abut against the bolt and vibrate it, thereby reducing the tightening force caused by the bolt sticking together. Then, the rotary motor 201 is activated to drive the transmission component 202 to transmit power. The output end of the rotary motor 201 drives the worm to rotate. The outer surface of the worm meshes with the worm wheel. The worm wheel drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the rotating table 204 to rotate, thereby causing the rotating table 204 to drive the clamping rod 302 and the clamping head 303 to rotate, thus completing the disassembly of the bolt. Afterwards, the disassembled bolt is collected using the collection box 305.
