Description

Technical Field

[0001] This utility model relates to the field of maintenance tools and is a special platform for bearing repair. Background Technology

[0002] Compressor equipment plays a core role in chemical enterprises, encompassing various structural forms such as centrifugal and reciprocating compressors. As a critical component, bearings are typically made of wear-resistant materials such as bronze or anti-friction alloys, featuring a semi-cylindrical structure and a highly smooth surface. During compressor operation, the bearings perform multiple functions by forming a continuous oil film: supporting and precisely positioning the rotating shaft, significantly reducing friction and wear, efficiently transferring working heat, and withstanding dynamic load impacts. The fitting precision between the bearing and the rotating shaft directly determines the rotational stability of the shaft system. Poor lubrication or a lack of oil film will lead to direct contact friction between the bearing and the shaft, causing severe wear.

[0003] The operating condition of bearings has a decisive impact on the overall reliability of compressor operation. When bearings wear or have abnormal clearances, it can lead to increased equipment vibration and shaft misalignment, potentially causing sudden compressor shutdowns in severe cases. A well-designed bearing system can effectively suppress friction-related faults such as journal scratches and bearing seizure by optimizing oil film distribution and material properties, thereby extending the compressor's service life. Especially in large units, where the number of bearings can reach hundreds, their performance stability directly affects the continuous and safe operation of the production system.

[0004] Regular maintenance of bearing bushes offers significant economic advantages, being more cost-effective than replacing the entire bearing assembly. In practice, maintenance should be categorized according to the degree of damage: bearing bushes with severe surface chipping or deep scratches should be replaced, while those with minor damage should be repaired. Traditional repair processes have significant drawbacks, typically requiring multiple people to work together, using wooden clamps to hold the bearing bush in place before manual scraping. During this process, the bearing bush is prone to misalignment or difficulty in directional adjustment, leading to secondary scratches and failure. This not only consumes a large amount of manpower and time but also makes it difficult to guarantee repair accuracy that meets operational requirements, necessitating improvements in repair technology. Summary of the Invention

[0005] This utility model provides a special platform for bearing repair, which overcomes the shortcomings of the prior art and can effectively solve the problem that there is no special fixture for existing bearing repair operations.

[0006] The technical solution of this utility model is achieved through the following measures: A special platform for bearing repair includes a support plate, a retaining edge, a clamping device, a support column, and a fixing device. The support plate includes a left inclined plate, a middle plate, and a right inclined plate arranged sequentially from left to right. The left inclined plate is inclined with the left side higher than the right side, and the right inclined plate is inclined with the left side lower than the right side. The right end of the left inclined plate is fixedly installed with the left end of the middle plate, and the left end of the right inclined plate is fixedly installed with the right end of the middle plate. A retaining edge is fixedly installed on the rear side of the support plate, and a clamping device is provided on the front side of the support plate to clamp the bearing on the upper side of the support plate and make the rear side of the bearing abut against the retaining edge. A support column is fixedly installed in the center of the lower side of the middle plate, and a fixing device that can be detachably and fixedly installed with the inspection table is fixedly installed on the lower side of the support column.

[0007] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution: The aforementioned clamping device may include a left clamping nut, a right clamping nut, a left clamping bolt, and a right clamping bolt. The left clamping nut and the right clamping nut are fixedly installed at intervals on the left and right sides of the upper front end of the middle plate. The left clamping nut and the right clamping nut are respectively fixedly installed with left clamping bolt and right clamping bolt through threaded connection.

[0008] Both the left and right clamping bolts mentioned above can be wing bolts.

[0009] The above may also include anti-slip pads, with anti-slip pads fixedly installed at the rear ends of both the left and right clamping bolts, and anti-slip pads fixedly installed on the front side of the flange.

[0010] The aforementioned support column may include an adjusting screw, a fixed tube, an upper adjusting nut, a lower adjusting nut, an upper adjusting bolt, and a lower adjusting bolt. The adjusting screw, with its upper end located above it, is fixedly installed inside the fixed tube via a threaded connection. The upper end of the adjusting screw is fixedly installed together with the center of the lower side of the medium plate. The outer side of the fixed tube is provided with an upper adjusting hole and a lower adjusting hole that are spaced apart vertically and penetrate each other. The upper adjusting nut and the lower adjusting nut are respectively fixedly installed on the outer side of the fixed tube at the positions corresponding to the upper adjusting hole and the lower adjusting hole. The upper adjusting bolt and the lower adjusting bolt, with their inner ends abutting against the corresponding positions on the outer side of the adjusting screw, are respectively fixedly installed inside the upper adjusting nut and the lower adjusting nut.

[0011] Both the upper and lower adjusting bolts mentioned above can be wing bolts.

[0012] The aforementioned fixing device may include a clamping block, a fixing bolt, and a handwheel. A clamping block is fixedly installed at the lower end of the support column. The clamping block is U-shaped and has a mounting screw hole in the center of the lower part. A fixing bolt is fixedly installed in the mounting screw hole through a threaded connection. A handwheel is fixedly installed on the outer side of the lower end of the fixing bolt.

Detailed Implementation

[0017] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0018] In this utility model, for ease of description, the description of the relative positional relationships of the components is based on the appendix to the specification. Figure 1 The layout is described using a central A-axis method, and the positional relationships such as front, back, top, bottom, left, and right are determined based on the layout direction of the attached diagram in the instruction manual.

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 2As shown, the special platform for bearing repair includes a support plate 1, a retaining edge 2, a clamping device, a support column, and a fixing device. The support plate 1 includes a left inclined plate, a middle plate, and a right inclined plate arranged sequentially from left to right. The left inclined plate is inclined with the left side higher than the right side, and the right inclined plate is inclined with the left side lower than the right side. The right end of the left inclined plate is fixedly installed with the left end of the middle plate, and the left end of the right inclined plate is fixedly installed with the right end of the middle plate. The retaining edge 2 is fixedly installed on the rear side of the support plate 1. The front side of the support plate 1 is provided with a clamping device that can clamp the bearing 17 on the upper side of the support plate 1 and make the rear side of the bearing 17 abut against the retaining edge 2. A support column is fixedly installed in the center of the lower side of the middle plate, and a fixing device that can be detachably and fixedly installed with the maintenance table is fixedly installed on the lower side of the support column. During use, by setting the left inclined plate, the middle flat plate, and the right inclined plate, the contact area between the bearing bush 17 and the support plate 1 is increased after the bearing bush 17 is placed behind the support plate 1, preventing the bearing bush 17 from rolling. The clamping device abuts against the front of the bearing bush 17 and makes the rear of the bearing bush 17 contact the retaining edge 2, thereby restricting the movement of the bearing bush 17. The fixing device facilitates quick installation of this tool onto the edge of the maintenance table. This utility model effectively solves the problem of the lack of dedicated clamps for existing bearing bush 17 repair operations, prevents operators from being injured by the bearing bush 17 during the repair process, saves manpower, simplifies the work, and has a simple and convenient structure.

[0020] The aforementioned dedicated platform for bearing repair can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 1 , 2 As shown, the clamping device includes a left clamping nut 3, a right clamping nut 4, a left clamping bolt 5, and a right clamping bolt 6. The left clamping nut 3 and right clamping nut 4 are fixedly installed at intervals on the left and right sides of the upper front end of the middle plate. The left clamping nut 3 and right clamping nut 4 are respectively fixedly installed with left clamping bolt 5 and right clamping bolt 6 through threaded connections. During use, the clamping and fixing method of the left clamping bolt 5 and right clamping bolt 6 using set screws significantly improves the stability and controllability of the bearing bush 17 repair operation. The axial clamping force generated by the rotation of the threads of the left clamping bolt 5 and right clamping bolt 6 can achieve precise positioning and secure locking of the bearing bush 17, completely eliminating the risk of bearing bush 17 displacement caused by sliding of the contact surface or uneven force in traditional wooden clamps. Its core advantage lies in the quantifiable and adjustable clamping force. The operator can precisely control the clamping force according to the material strength and damage degree of the bearing bush 17, ensuring the absolute stillness of the bearing bush 17 during the repair process while avoiding substrate deformation or surface indentation caused by excessive clamping. This mechanical fastening method not only simplifies the repair work from multi-person collaboration to single-person operation, but also provides a stable benchmark for precise control of the scraper trajectory through the combination of rigid constraints and flexible adjustments, fundamentally ensuring the geometric accuracy and surface quality of the repaired bearing bush 17.

[0021] Example 3: As shown in the attached documentFigure 1 , 2 As shown, both the left clamping bolt 5 and the right clamping bolt 6 are wing bolts. During use, the unique wing-shaped handle design of the wing bolts allows the operator to tighten or loosen the left clamping bolt 5 or the right clamping bolt 6 directly by hand, without the need for additional tools such as wrenches, greatly improving the ease of operation.

[0022] Example 4: As shown in the appendix Figure 1 , 2 As shown, it also includes anti-slip pads 7. Anti-slip pads 7 are fixedly installed at the rear ends of both the left clamping bolt 5 and the right clamping bolt 6, and anti-slip pads 7 are fixedly installed on the front side of the retaining edge 2. During use, placing anti-slip pads 7 on the contact surfaces between the tool and the bearing bush 17 effectively improves the reliability of the repair process and the protection of the bearing bush 17. Anti-slip pads 7 are typically made of soft, elastic material with a textured surface possessing a high coefficient of friction. This allows them to closely conform to the curved surface of the bearing bush 17, significantly increasing the frictional resistance between the contact surfaces, thereby completely avoiding the risk of secondary damage caused by the sliding or displacement of the bearing bush 17 in traditional clamping methods. Simultaneously, the flexible buffering characteristics of the anti-slip pads 7 can evenly distribute clamping pressure, preventing hard parts of the clamp from directly contacting the surface of the bearing bush 17 and causing indentations or scratches, thus fully ensuring the integrity of the bearing bush 17's surface precision. In addition, the anti-slip pad 7's adaptive deformation capability can adapt to the curved contours of different specifications of bearing bush 17, ensuring a uniform distribution of clamping force and keeping the bearing bush 17 in a stable posture during the scraping process. This provides a reliable basis for precise control of the scraper trajectory and ultimately significantly improves the yield rate and operational safety of the repair operation.

[0023] Example 5: As shown in the attached document Figure 1 , 2 As shown, the support column includes an adjusting screw 8, a fixed tube 9, an upper adjusting nut 10, a lower adjusting nut 11, an upper adjusting bolt 12, and a lower adjusting bolt 13. The adjusting screw 8, with its upper end located above it, is fixedly installed inside the fixed tube 9 via a threaded connection. The upper end of the adjusting screw 8 is fixedly installed together with the center of the lower side of the medium plate. The outer side of the fixed tube 9 is provided with an upper adjusting hole and a lower adjusting hole that are spaced apart vertically and horizontally. The upper adjusting nut 10 and the lower adjusting nut 11 are fixedly installed on the outer side of the fixed tube 9 at the positions corresponding to the upper and lower adjusting holes, respectively. The upper adjusting bolt 12 and the lower adjusting bolt 13, with their inner ends abutting against the corresponding positions on the outer side of the adjusting screw 8, are fixedly installed inside the upper adjusting nut 10 and the lower adjusting nut 11, respectively. During use, by installing the adjusting screw 8 in the fixed tube 9 using a threaded connection, the height, angle, and position of the support plate 1 can be easily adjusted to meet the repair work of the bearing 17 under different working environments. By setting the upper adjusting bolt 12 and the lower adjusting bolt 13, the upper adjusting bolt 12 can be tightened and pressed against the outer wall of the adjusting screw 8, thereby locking the position of the adjusting screw 8 and preventing it from rotating.

[0024] Example 6: As attachedFigure 1 , 2 As shown, both the upper adjusting bolt 12 and the lower adjusting bolt 13 are wing bolts. During use, the unique wing-shaped handle design of the wing bolts allows the operator to tighten or loosen the upper adjusting bolt 12 or the lower adjusting bolt 13 directly by hand, without the need for additional tools such as wrenches, greatly improving the ease of operation.

[0025] Example 7: As attached Figure 1 , 2 As shown, the fixing device includes a clamping block 14, a fixing bolt 15, and a handwheel 16. The clamping block 14 is fixedly installed at the lower end of the support column. The clamping block 14 is U-shaped, and a mounting screw hole is provided in the center of the lower part of the clamping block 14. The fixing bolt 15 is fixedly installed in the mounting screw hole through a threaded connection. The handwheel 16 is fixedly installed on the outer side of the lower end of the fixing bolt 15. During use, by setting up the fixing device to fix the tool to the edge of the repair table, the stability and efficiency of the bearing bush 17 repair operation can be significantly improved. This fixing device firmly locks the tool position through a quick clamping mechanism, effectively avoiding the risk of secondary scratches caused by the bearing bush 17's deviation or orientation adjustment when using traditional wooden clamps. At the same time, a single person can complete the installation and positioning of the tool, without the need for multiple people to cooperate in clamping the bearing bush 17, greatly reducing manpower consumption and operation time. In addition, the rigid fixation of the clamping block 14 to the edge of the table ensures the absolute stability of the tool during the scraping process, providing a basis for precise control of the scraper force and angle, significantly improving the surface repair quality of the bearing bush 17, and making it easier to meet the precision requirements of compressor operation.

[0026] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
