Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a compressor maintenance tool. Background Technology

[0002] A screw compressor is a positive displacement compressor. Its core function is to continuously draw in, compress, and discharge high-pressure gas through the rotational motion of a pair of meshing helical rotors, thereby converting mechanical energy into the pressure energy of the gas.

[0003] A screw compressor draws in atmospheric or low-pressure gas (usually air, but can also be other process gases, refrigerants, etc.), compresses the gas within the rotor chamber by continuously reducing its volume, and finally discharges gas with significantly increased pressure. The compressed high-pressure air is one of the power sources in the industrial field, generally used to drive various pneumatic tools, pneumatic equipment, control instruments, etc. In refrigeration, industrial refrigeration, and central air conditioning systems, the screw compressor is the main refrigerant compression component. It draws in low-temperature, low-pressure refrigerant gas, compresses it into high-temperature, high-pressure gas, and then sends it to the condenser for heat dissipation, thereby driving the entire refrigeration cycle.

[0004] The rotor of a screw compressor is typically bolted to a disc. When disassembling the rotor disc, it is necessary to manually hold the disc in place to prevent it from rotating with the rotor when the bolts are turned. However, manually holding the disc presents a risk of slippage and damage due to uneven force distribution. Furthermore, during rotor and disc assembly, a tightening torque is required, and manually holding the disc makes it difficult to ensure that the bolts securing it to the disc reach the required torque. Therefore, there is room for improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a compressor maintenance tool that can fix the wheel disc to the compressor housing, avoid slippage and damage to the wheel disc when disassembling it, and ensure that the torque of the bolts fixing the wheel disc meets the installation requirements when installing the wheel disc after maintenance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a compressor maintenance tool, comprising:

[0007] The first mounting plate is used to connect to the compressor housing;

[0008] Connecting frame, wherein the connecting frame is detachably connected to the first mounting plate;

[0009] The second mounting plate is used to connect the rotor disc of the compressor, and the second mounting plate is detachably connected to the connecting frame.

[0010] Specifically, when the compressor needs maintenance, the first mounting plate and the second mounting plate are first installed on the connecting bracket. The distance between the first and second mounting plates is sufficient to allow the second mounting plate to be connected to the wheel when the first mounting plate is connected to the compressor housing. Then, the first mounting plate is connected to the compressor housing, and the second mounting plate is connected to the wheel. Since the first and second mounting plates are relatively fixed by the connecting bracket, the wheel can be relatively fixed to the compressor housing. At this point, when the bolts fixing the wheel are turned, the wheel will not rotate, preventing slippage and damage to the wheel during disassembly. Furthermore, when installing the wheel after maintenance, it ensures that the torque of the bolts fixing the wheel meets the installation requirements.

[0011] Optionally, the first mounting plate includes:

[0012] The first fixing part is used to connect the compressor housing;

[0013] The second fixing part is set at an angle to the first fixing part, and the second fixing part is detachably connected to the connecting frame.

[0014] Specifically, the first fixing part, as a component directly connected to the compressor housing, can connect with the mounting holes of the flange on the edge of the compressor body, preventing tool displacement. The angle design between the second fixing part and the first fixing part can precisely adapt to the spatial misalignment between the compressor body and the wheel, allowing the connecting bracket to extend smoothly to the wheel position. Its detachable connection with the connecting bracket, combined with the operating space provided by the angle, facilitates tool disassembly and maintenance.

[0015] The first fixing part and the second fixing part are integrally formed. The integrated angle structure of the two eliminates the angular deviation of the split mounting plate, improves the overall torsional strength, and can evenly transmit the reverse torsional force during maintenance to the outer shell, avoiding tool failure. This reduces the risk of wheel damage and ensures the bolt tightening accuracy.

[0016] Optionally, a plurality of sliding holes are provided on the second fixing part, the sliding holes extending along the length direction of the second fixing part, and the connecting frame is detachably connected to the second fixing part through the plurality of sliding holes.

[0017] Specifically, by providing sliding holes extending along the length of the second fixing part, the connecting bracket can move along the length of the sliding holes, thereby adjusting the relative distance between the first fixing part and the second mounting plate. This allows the second mounting plate to precisely align with wheel discs of different specifications, eliminating the need to design separate tools for each type of compressor and significantly improving the tool's versatility and applicability. Simultaneously, the multiple sliding holes distribute the connection stress, preventing component deformation caused by single-point connections and further ensuring the structural stability of the tool during adjustment and use.

[0018] Optionally, the sliding hole is an oblong hole.

[0019] Specifically, the arc-shaped end design of the waist-shaped hole can prevent the first fixing part from getting stuck or rubbing against the edge of the hole wall when the connecting frame moves, ensuring a smooth adjustment process; its straight section length can accurately match the distance adjustment range between the common compressor disc and the housing, which not only meets the effective adjustment needs, but also avoids the connecting frame from shaking due to excessive hole length.

[0020] Optionally, the connecting frame includes:

[0021] The first connecting part has a plurality of through holes that correspond one-to-one with a plurality of sliding holes. A first fixing member is provided in the through hole, and the through hole is detachably connected to the corresponding sliding hole through the first fixing member.

[0022] The second connecting part is arranged at an angle to the first connecting part;

[0023] The third connecting part is set at an angle to the second connecting part, and the third connecting part is detachably connected to the second mounting plate.

[0024] Specifically, the first connecting part mates with the sliding hole of the first mounting plate through a through hole. By adjusting the relative position of the first connecting part and the first mounting plate, the second mounting plate on the third connecting part can fit against the wheel. The second connecting part forms an angle with the first connecting part, which can change the direction of force transmission and avoid spatial interference between the connecting frame and the compressor cylinder. The third connecting part forms an angle with the second connecting part, ensuring that the second mounting plate can be fixed on the third connecting part at an angle parallel to the wheel. This multi-segment angled design allows the connecting frame to flexibly adapt to the complex spatial layout of the compressor housing, improving the compatibility with compressors of different sizes.

[0025] Optionally, a hollow groove is provided on the first connecting part.

[0026] Specifically, a perforated groove is created in the first connecting part. On the one hand, the perforated groove can remove unnecessary material from the first connecting part, reducing the overall weight of the tool, lessening the physical burden on operators during installation and disassembly, and improving ease of use. On the other hand, a reasonable perforated structure can optimize the stress distribution of the first connecting part, avoiding excessive local stress caused by material concentration, while not affecting the overall rigidity of the connecting part. In addition, the perforated groove can also reduce the amount of processing material used, lowering the tool manufacturing cost.

[0027] Optionally, the first fastener includes a first screw and a first nut, wherein the first screw passes through the through hole and the sliding hole in sequence and is threadedly connected to the first nut.

[0028] Specifically, when it is necessary to adjust the relative position of the connecting bracket and the first mounting plate, first pass the first screw through the through hole and the sliding hole in sequence, and leave the first nut loose. At this time, the first screw can move in the sliding hole, thereby changing the relative position of the second fixing part and the first fixing part, so that the second fixing part can fit against the compressor disc. Then tighten the first nut to fix the position of the connecting bracket and the first mounting plate, and avoid the tool from shifting due to loose connection.

[0029] Optionally, the second mounting plate has a plurality of fixing holes corresponding to the disc of the compressor rotor, and the connecting bracket has at least one connecting hole adapted to the fixing holes. A second fixing member is provided in the connecting hole, and the connecting hole is detachably connected to the corresponding fixing hole through the second fixing member.

[0030] Specifically, by setting several fixing holes, the second mounting plate can be connected to the wheel at multiple points, distributing the force and avoiding tilting or deformation of the second mounting plate caused by single-point connection. This ensures that the second mounting plate can be accurately aligned with the wheel after installation, reducing positioning deviations. Connecting holes are provided on the connecting frame, and the second fixing component passes through these holes to install the second mounting plate onto the connecting frame. Furthermore, the detachable connection feature allows for easy replacement of the second mounting plate with a suitable one according to the wheel specifications, further enhancing the tool's versatility.

[0031] Optionally, the second fastener includes a second screw and a second nut, wherein the second screw passes through the connecting hole and the fixing hole in sequence and is threadedly connected to the second nut.

[0032] Specifically, using a second screw and a second nut to connect the second mounting plate and the connecting bracket provides a reliable and convenient way to connect the second mounting plate and the connecting bracket. The high strength of the threaded connection of the second screw and the second nut ensures that the second mounting plate does not loosen when locking the wheel and bearing the reaction force of bolt tightening, thus guaranteeing the fixing effect of the second mounting plate and the connecting bracket.

[0033] Optionally, a positioning pin is provided in the fixing hole, and the positioning pin is used to insert the rotor disc of the compressor.

[0034] Specifically, the locating pin can be inserted into the pre-set locating hole of the compressor rotor disc, restricting the disc's circumferential rotation and completely eliminating the risk of slippage during manual fixing. Simultaneously, the guiding function of the locating pin assists the second mounting plate in quickly and accurately aligning the disc, reducing positioning adjustment time during installation and improving maintenance efficiency. Furthermore, the tight fit between the locating pin and the fixing hole reduces the gap between the disc and the second mounting plate, preventing slight displacement of the disc when tightening bolts, ensuring precise torque transmission, and further guaranteeing the assembly quality and service life of the compressor after maintenance.

[0035] In summary, this utility model has the following beneficial effects:

[0036] When compressor maintenance is required, first install the first and second mounting plates onto the connecting bracket, ensuring the distance between them is sufficient for the second mounting plate to connect to the wheel disc when the first mounting plate is connected to the compressor housing. Then, connect the first mounting plate to the compressor housing and the second mounting plate to the wheel disc. Since the first and second mounting plates are relatively fixed via the connecting bracket, the wheel disc can be relatively fixed to the compressor housing. At this point, turning the bolts securing the wheel disc will prevent it from rotating, avoiding slippage and damage during disassembly. Furthermore, this ensures that the bolts securing the wheel disc will be tightened to the required torque when reinstalling it after maintenance. Attached Figure Description

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] Example 1

[0046] This embodiment provides a compressor repair tool, such as... Figure 1 and Figure 4 As shown, it includes: a first mounting plate 100 for connecting to the compressor housing 400;

[0047] A connecting frame 200 is detachably connected to the first mounting plate 100;

[0048] The second mounting plate 300 is used to connect the rotor disc 500 of the compressor, and the second mounting plate 300 is detachably connected to the connecting frame 200.

[0049] Specifically, when the compressor needs to be repaired, the first mounting plate 100 and the second mounting plate 300 are first installed on the connecting bracket 200, ensuring that the distance between the first mounting plate 100 and the second mounting plate 300 is sufficient for the second mounting plate 300 to be connected to the wheel 500 when the first mounting plate 100 is connected to the compressor housing 400. Then, the first mounting plate 100 is connected to the compressor housing 400, and the second mounting plate 300 is connected to the wheel 500. Since the first mounting plate 100 and the second mounting plate 300 are relatively fixed through the connecting bracket 200, the wheel 500 can be relatively fixed to the compressor housing 400. At this point, when the bolts fixing the wheel 500 are turned, the wheel 500 will no longer rotate, preventing slippage and damage to the wheel 500 during disassembly. Furthermore, when the wheel 500 is installed after maintenance, the torque of the bolts fixing the wheel 500 is ensured to meet the installation requirements.

[0050] Since there is an obstruction between the flange on the compressor housing 400 and the rotor disc 500, a connecting bracket 200 is needed to connect the first mounting plate 100 and the second mounting plate 300 to avoid obstructing the compressor housing 400.

[0051] When overhauling the compressor, first confirm its status, stop the compressor and disconnect the power source. After the internal pressure is completely released, clean the dust and oil from the flange of the compressor housing 400 and the surface of the rotor disc 500, ensuring that the connecting surface between the first mounting plate 100 and the housing, and the contact surface between the second mounting plate 300 and the disc 500, are free of impurities to avoid affecting positioning accuracy. Fit the connecting surface of the first mounting plate 100 to the flange of the compressor housing 400 using bolts or riveting to ensure a tight connection and prevent relative movement between the first mounting plate 100 and the flange. Then, fix the second mounting plate 300 to the connecting bracket 200, with one end of the connecting bracket 200 close to the connecting surface of the first mounting plate 100. Simultaneously observe the relative position of the other end of the connecting bracket 200 and the disc 500, ensuring the second mounting plate 300 is in contact with the disc 500. Finally, fix the connecting bracket 200 to the first mounting plate 100. The second mounting plate 300 and the wheel 500 can be connected by bolts, rivets, or locating pins to restrict the circumferential rotation of the wheel 500. At this time, since the second mounting plate 300 and the first mounting plate 100 are relatively fixed by the connecting frame 200, a complete rigid chain of "compressor housing 400, first mounting plate 100, connecting frame 200, second mounting plate 300, and wheel 500" is formed. The wheel 500 cannot rotate or move. At this time, the bolts fixing the wheel 500 can be rotated and removed to meet the maintenance operation conditions for repairing the compressor rotor.

[0052] After the compressor is overhauled, maintain the complete rigid chain of "compressor housing 400, first mounting plate 100, connecting bracket 200, second mounting plate 300, and wheel 500". When assembling the rotor, pass the bolts that fix the wheel 500 through the wheel 500 and apply a standardized tightening torque to the bolts to ensure that the bolts tightly connect the wheel 500 and the rotor, thereby improving the service life of the compressor.

[0053] Example 2

[0054] Please see Figure 1 , Figure 2 and Figure 4 Based on the above embodiment one, the difference between this embodiment and embodiment one is that the compressor maintenance tool in this embodiment includes the following: the first mounting plate 100 includes:

[0055] The first fixing part 110 is used to connect the compressor housing 400;

[0056] The second fixing part 120 is set at an angle to the first fixing part 110, and the second fixing part 120 is detachably connected to the connecting frame 200.

[0057] Specifically, the first fixing part 110, as a component directly connected to the compressor housing 400, can connect to the mounting hole 111 of the flange hole on the edge of the compressor body, preventing tool displacement. The angle design between the second fixing part 120 and the first fixing part 110 can precisely adapt to the spatial misalignment between the compressor body and the wheel 500, allowing the connecting bracket 200 to extend smoothly to the position of the wheel 500. The detachable connection between the connecting bracket 200 and the angle provides operating space, facilitating tool disassembly and maintenance.

[0058] The first fixing part 110 and the second fixing part 120 are integrally formed. The integrated angle structure of the two eliminates the angular deviation of the split mounting plate, improves the overall torsional strength, and can evenly transmit the reverse torsional force during maintenance to the outer shell, avoiding tool failure. This reduces the risk of damage to the wheel 500 and ensures the bolt tightening accuracy.

[0059] In this embodiment, the first fixing part 110 is provided with a mounting hole 111. After the screw passes through the mounting hole 111 and the flange hole of the compressor housing 400, it is connected with the nut to fix the first fixing part 110 to the compressor housing 400.

[0060] In this embodiment, there are two mounting holes 111, which are symmetrically arranged about the central axis of the first fixing part 110. The mounting holes 111 are oblong holes, and the extension direction of the mounting holes 111 is perpendicular to the central axis of the first fixing part 110. At this time, the distance between the screws passing through the two mounting holes 111 can be adjusted according to the flange hole of the compressor housing 400 to adapt to compressor housings 400 of different sizes.

[0061] Optionally, a plurality of sliding holes 121 are provided on the second fixing part 120, the sliding holes 121 extending along the length direction of the second fixing part 120, and the connecting frame 200 is detachably connected to the second fixing part 120 through the plurality of sliding holes 121.

[0062] Specifically, by providing a sliding hole 121 extending along the length direction in the second fixing part 120, the connecting bracket 200 can move along the length direction of the sliding hole 121, thereby adjusting the relative distance between the first fixing part 110 and the second mounting plate 300. This allows the second mounting plate 300 to accurately align with wheel discs 500 of different specifications, eliminating the need to design tools separately for each type of compressor and significantly improving the tool's versatility and applicability. Simultaneously, the arrangement of multiple sliding holes 121 can distribute the connection force, avoiding component deformation caused by single-point connections, further ensuring the structural stability of the tool during adjustment and use.

[0063] Optionally, the sliding hole 121 is an oblong hole.

[0064] Specifically, the arc-shaped end design of the waist-shaped hole can prevent the first fixing part from getting stuck or rubbing against the edge of the hole wall when the connecting bracket 200 moves, ensuring a smooth adjustment process; its straight section length can accurately match the distance adjustment range between the common compressor wheel 500 and the outer shell, which not only meets the effective adjustment needs, but also avoids the connecting bracket 200 from shaking due to excessive hole length.

[0065] In this embodiment, two sliding holes 121 are provided and are symmetrically arranged along the central axis of the second fixed plate, which can ensure that the torque borne by the two sliding holes 121 is balanced.

[0066] In this embodiment, the included angle between the first fixing part 110 and the second fixing part 120 is 90°, so that the connecting frame 200 can move perpendicularly to the first fixing part 110 along the sliding hole 121, thereby driving the second mounting plate 300 connected to the other end of the connecting frame 200 to move perpendicularly to the first fixing part 110, changing the relative distance between the second mounting plate 300 and the first fixing part 110 to adapt to compressor housings 400 of different sizes.

[0067] Example 3

[0068] Please see Figures 1-4 Based on any of the above embodiments, the difference between this embodiment and any of the above embodiments is that, in this embodiment, a compressor maintenance tool includes a connecting frame 200 comprising:

[0069] The first connecting part 210 has a plurality of through holes 213 corresponding to a plurality of sliding holes 121. A first fixing member is provided in the through hole 213, and the through hole 213 is detachably connected to the corresponding sliding hole 121 through the first fixing member.

[0070] The second connecting portion 220 is arranged at an angle to the first connecting portion 210;

[0071] The third connecting part 230 is set at an angle to the second connecting part 220, and the third connecting part 230 is detachably connected to the second mounting plate 300.

[0072] Specifically, the first connecting part 210 engages with the sliding hole 121 of the first mounting plate 100 through the through hole 213. By adjusting the relative positions of the first connecting part 210 and the first mounting plate 100, the second mounting plate 300 on the third connecting part 230 can fit against the wheel 500. The second connecting part 220 forms an angle with the first connecting part 210, which can change the direction of force transmission and avoid spatial interference between the connecting frame 200 and the compressor cylinder. The third connecting part 230 forms an angle with the second connecting part 220, ensuring that the second mounting plate 300 can be fixed on the third connecting part 230 at an angle parallel to the wheel 500. This multi-segment angled design allows the connecting frame 200 to flexibly adapt to the complex spatial layout of the compressor housing 400, improving the compatibility with compressors of different sizes.

[0073] In this embodiment, the angle between the first connecting part 210 and the second connecting part 220 is 90°, and the angle between the second connecting part 220 and the third connecting part 230 is 90°, so that the first connecting part 210 and the second connecting part 220 are parallel to each other, and the first connecting part 210 is perpendicularly connected to the second fixing part 120, so that the second mounting plate 300 connected to the third connecting part 230 can be parallel to the first fixing part 110.

[0074] Optionally, the first connecting part 210 is provided with a hollow groove 211.

[0075] Specifically, a hollowed-out groove 211 is formed in the first connecting part 210. On the one hand, the hollowed-out groove 211 can remove unnecessary material from the first connecting part 210, reducing the overall weight of the tool, reducing the physical burden on operators during installation and disassembly, and improving ease of use. On the other hand, the reasonable hollowed-out structure can optimize the stress distribution of the first connecting part 210, avoiding excessive local stress caused by material concentration, while not affecting the overall rigidity of the first connecting part 210. In addition, the hollowed-out groove 211 can also reduce the amount of processing material used, reducing the tool manufacturing cost.

[0076] In this embodiment, two hollowed-out grooves 211 are provided and are symmetrically arranged about the central axis of the width direction of the first connecting part 210. The two hollowed-out grooves 211 provide a support rod 212 in the middle of the width direction of the first connecting part 210. The support rod 212 can optimize the stress distribution of the first connecting part 210 when the bolt is twisted, so as not to affect the overall rigidity of the first connecting part 210.

[0077] Example 4

[0078] Please see Figures 1-3Based on any of the above embodiments, the difference between this embodiment and any of the above embodiments is that, in this embodiment, a compressor maintenance tool includes a first fixing member comprising a first screw and a first nut, wherein the first screw passes through the through hole 213 and the sliding hole 121 in sequence and is threadedly connected to the first nut.

[0079] Specifically, when it is necessary to adjust the relative position of the connecting bracket 200 and the first mounting plate 100, firstly, pass the first screw through the through hole 213 and the sliding hole 121 in sequence, and do not tighten the first nut. At this time, the first screw can move in the sliding hole 121, thereby changing the relative position of the second fixing member and the first fixing member, so that the second fixing member can fit with the compressor's wheel 500. Then tighten the first nut to fix the position of the connecting bracket 200 and the first mounting plate 100, and avoid the tool from shifting due to loose connection.

[0080] Example 5

[0081] Please see Figure 1 and Figure 3 Based on any of the above embodiments, the difference between this embodiment and any of the above embodiments is that, in this embodiment, a compressor maintenance tool is provided, the second mounting plate 300 is provided with a plurality of fixing holes 310 corresponding to the wheel 500 of the compressor rotor, the connecting frame 200 is provided with at least one connecting hole 231 adapted to the fixing holes 310, the connecting hole 231 is provided with a second fixing member, and the connecting hole 231 is detachably connected to the corresponding fixing hole 310 through the second fixing member.

[0082] Specifically, by providing several fixing holes 310, the second mounting plate 300 can be connected to the wheel 500 at multiple points, distributing the force and preventing tilting or deformation of the second mounting plate 300 caused by single-point connection. This ensures that the second mounting plate 300 can be accurately aligned with the wheel 500 after installation, reducing positioning deviation. Furthermore, a connecting hole 231 is provided on the connecting frame 200. The second fixing member passes through the connecting hole 231 and the fixing holes 310 to install the second mounting plate 300 onto the connecting frame 200. In addition, the detachable connection feature facilitates the replacement of the second mounting plate 300 with a suitable one according to the wheel 500 specifications, further improving the tool's versatility.

[0083] In this embodiment, the second mounting plate 300 is annular, and its size is consistent with the size of the compressor disc 500 to be inspected, thereby ensuring precise alignment of the disc 500. Furthermore, since the second mounting plate 300 is detachably connected to the connecting bracket 200, a corresponding second mounting plate 300 can be designed for compressor discs 500 of different sizes. During use, only the second mounting plate 300 needs to be replaced to allow for the assembly and disassembly of compressor discs 500 of different sizes.

[0084] Example 6

[0085] Please see Figure 4 Based on any of the above embodiments, the difference between this embodiment and any of the above embodiments is that, in this embodiment, a compressor maintenance tool includes a second fixing member comprising a second screw and a second nut, wherein the second screw passes through the connecting hole 231 and the fixing hole 310 in sequence and is threadedly connected to the second nut.

[0086] Specifically, using a second screw and a second nut to connect the second mounting plate 300 and the connecting bracket 200 provides a reliable and convenient way to connect them. The high strength of the threaded connection of the second screw and the second nut ensures that the second mounting plate 300 does not loosen when locking the wheel 500 and bearing the reaction force of bolt tightening, thus guaranteeing the fixing effect of the second mounting plate 300 and the connecting bracket 200.

[0087] Optionally, a positioning pin is provided in the fixing hole 310, which is used to insert the compressor rotor disc 500.

[0088] Specifically, the locating pin can be inserted into the preset locating hole of the compressor rotor disc 500, restricting the circumferential rotation of the disc 500 and completely eliminating the risk of slippage during manual fixing. Simultaneously, the guiding function of the locating pin assists the second mounting plate 300 in quickly and accurately aligning with the disc 500, reducing positioning adjustment time during installation and improving maintenance efficiency. Furthermore, the tight fit between the locating pin and the fixing hole 310 reduces the gap between the disc 500 and the second mounting plate 300, preventing slight displacement of the disc 500 when tightening bolts, ensuring precise torque transmission, and further guaranteeing the assembly quality and service life of the compressor after maintenance.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
