Description

Technical Field

[0001] The invention relates to the technical field of centrifugal compressors, and in particular to a quick disassembly and maintenance structure for centrifugal compressors. Background Art

[0002] A centrifugal compressor is a device that uses rotational motion to convert mechanical energy into gas pressure energy. It is widely used in various industrial fields where gas pressure needs to be increased or a large amount of gas needs to be transported. It applies centrifugal force to the incoming gas through a high-speed rotating impeller (also called a rotor), so that the gas gains kinetic energy, and converts the kinetic energy into static pressure energy in the subsequent expansion process.

[0003] During routine maintenance, centrifugal compressors usually only require simple inspection, cleaning, and replacement of worn parts without removal from the mounting platform. However, when performing in-depth repairs or replacing core components of a centrifugal compressor, it is necessary to remove the entire compressor from the original mounting platform for comprehensive maintenance.

[0004] However, there are usually some problems when disassembling and maintaining centrifugal compressors. With the development of science and technology, technicians in related fields have also made a lot of optimizations on the disassembly and maintenance of centrifugal compressors. In order to make a more accurate comparison, a Chinese patent with publication number CN117399184A discloses a quick-disassembly centrifuge, including a frame and a centrifuge body. The frame includes a body and a connecting assembly. A working chamber is provided in the body, an opening communicating with the working chamber is provided on the body, a connecting assembly is arranged in the body, a connecting plate is provided on the top of the working chamber, a connecting mechanism is provided on the connecting plate, and the connecting assembly includes an upper connecting assembly and a lower connecting assembly.

[0005] When in use, the centrifuge body in the working chamber can be easily maintained and repaired through the opening, and the top of the quick-disassembly centrifuge can be checked separately, and parts can be replaced separately when they are damaged or mismatched; when disassembling, the connection between the centrifuge body and the connecting mechanism is released, and then the connection between the bottom of the centrifuge body and the lower end connecting component is released.

[0006] However, there are still some shortcomings in the process of disassembling and maintaining the centrifuge in the above-mentioned prior art:

[0007] 1. Although the centrifuge body can be installed and disassembled through the connecting mechanism, the specific structure of the connecting mechanism is not disclosed, so that the convenience of installing and disassembling the centrifuge body cannot be ensured, and it is difficult to ensure the stability of the centrifuge body after installation.

[0008] 2. Since the centrifugal compressor does not need to be removed during routine maintenance, but the locations that require maintenance may be different, the centrifugal compressor still needs to be removed when it is inconvenient for maintenance. Although the above-mentioned prior art can maintain the centrifuge body after opening, this method has limitations and it is difficult to perform comprehensive maintenance on the local location of the centrifuge body, thereby affecting the maintenance efficiency and effect.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in the disassembly, assembly and maintenance methods of existing centrifugal compressors. Summary of the invention

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-Figure 11 Embodiments of the present invention are described in detail.

[0045] The embodiment of the present application discloses a centrifugal compressor quick disassembly and maintenance structure. It should be noted that the centrifugal compressor quick disassembly and maintenance structure of the present application is mainly used in the process of quick installation, disassembly and maintenance of the compressor body 1. In terms of technical effect, the compressor body 1 can be quickly installed and disassembled, and the operation is convenient. There is no need to use more cumbersome bolts for installation and disassembly, which can effectively improve the disassembly and assembly efficiency of the compressor body 1, thereby reducing the time required for maintenance; especially when installing the compressor body 1, quick installation can be achieved by fixing its bottom feet in all directions, and its stability during use can be ensured; further, the centrifugal compressor quick disassembly and maintenance structure of the present application can also remove the compressor body 1 from the mounting platform 3, and local maintenance can be performed on it without removing it, which can effectively reduce the workload and improve the maintenance efficiency.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick disassembly and maintenance structure of a centrifugal compressor includes a compressor body 1, which is arranged on a mounting platform 3 through a supporting plate 2. The compressor body 1 and the supporting plate 2 are connected in a detachable manner, and two positioning plates 4 symmetrically distributed along its width direction are installed on the upper end of the supporting plate 2. The two positioning plates 4 are against both sides of the compressor body 1. The position of the compressor body 1 can be positioned through the positioning plates 4 to avoid its deviation and affect the installation efficiency; and the upper end of the supporting plate 2 is also provided with a clamping sleeve 5 for fastening and limiting one end of the bottom support foot of the compressor body 1 and a locking unit 6 for locking and limiting the other end of the bottom support foot of the compressor body 1.

[0047] Furthermore, in this embodiment, the locking unit 6 includes a clamping block 61 for pressing and locking the end of the bottom leg of the compressor body 1 away from the clamping sleeve 5, and a locking groove 62 matching with the clamping block 61 is formed at the upper end of the supporting plate 2.

[0048] During the specific implementation process, the compressor body 1 is first placed on the support plate 2, and then its bottom support foot is inserted into the clamping sleeve 5, and the bottom support foot of the compressor body 1 is limited by the clamping sleeve 5, and then the other bottom support foot of the compressor body 1 is locked and limited by the locking unit 6, so that the bottom support foot of the compressor body 1 can be fully limited and fixed by the clamping sleeve 5 and the locking unit 6, thereby ensuring the stability of the compressor body 1 after installation.

[0049] When the compressor body 1 needs to be removed, first disconnect it from the pipes and other connecting parts on the installation platform 3, then release the limiting effect of the locking unit 6 on the bottom support feet of the compressor body 1, and then push the compressor body 1 away from the clamping sleeve 5 to quickly release the limiting effect of the clamping sleeve 5 on the bottom support feet of the compressor body 1, so that the compressor body 1 can be quickly installed and disassembled, and it is convenient to maintain it and operate conveniently.

[0050] It should be noted that in order to facilitate the rapid insertion of the bottom support foot of the compressor body 1 into the interior of the clamping sleeve 5 and the rapid insertion of the compressor body 1 between the two positioning plates 4, in the present embodiment, a cavity matching the bottom support foot of the compressor body 1 is provided inside the clamping sleeve 5, and the upper end of the clamping sleeve 5 close to the compressor body 1 is gradually tilted upward to facilitate guiding the bottom support foot of the compressor body 1 so that it can be quickly inserted into the cavity. In addition, the upper ends of the two positioning plates 4 are gradually tilted away from each other to facilitate guiding the compressor body 1 so that it can be quickly clamped between the two positioning plates 4, which can further speed up the installation efficiency of the compressor body 1.

[0051] Reference Figure 3 , Figure 4 and Figure 5 As shown, in order to facilitate the stable locking of the end of the bottom support leg of the compressor body 1 away from the clamping sleeve 5, in the present embodiment, a through hole 11 corresponding to the position of the locking groove 62 is provided at the end of the bottom support leg of the compressor body 1 away from the clamping sleeve 5, and the locking unit 6 also includes a force-bearing plate 63 slidably docked on the inner wall of the through hole 11, and a plurality of contraction springs 64 are installed between the force-bearing plate 63 and the inner top wall of the through hole 11, and the clamping block 61 is installed at the lower end of the force-bearing plate 63 through a connecting plate 65; both inner walls of the locking groove 62 in the length direction are provided with a receiving groove 66, and an abutment plate 67 is slidably arranged in the receiving groove 66, and a top contact spring rod 68 is arranged between the abutment plate 67 and the inner wall of the locking groove 62.

[0052] It should be noted that the contraction spring 64 always applies a pulling force with an upward movement tendency to the force-bearing plate 63, so that the force-bearing plate 63 drives the clamping block 61 to be retracted upward into the through hole 11 through the connecting plate 65 in the initial state; in addition, the top contact spring rod 68 always applies a driving force to the abutment plate 67, so that the two abutment plates 67 extend from the accommodating groove 66 and abut against each other in the initial state.

[0053] It should be further explained that in order to facilitate the rapid insertion of the snap-in block 61 into the locking groove 62, in the present embodiment, the lower half of the snap-in block 61 is an inclined surface whose width gradually decreases from top to bottom, and the upper ends of the opposite sides of the two abutment plates 67 are provided with inclined chamfers that cooperate with the inclined surface of the snap-in block 61 and are parallel to each other.

[0054] During the specific implementation process, after one of the bottom legs of the compressor body 1 is inserted into the clamping sleeve 5, the through hole 11 of the other bottom leg of the compressor body 1 corresponds to the position of the locking groove 62. At this time, the force-bearing plate 63 is pressed, and the force-bearing plate 63 drives the clamping block 61 to move downward as a whole through the connecting plate 65, so that the clamping block 61 squeezes the two abutment plates 67 to both sides. Under the action of the extrusion force, the abutment plate 67 overcomes the elastic driving force of the top contact spring rod 68 and shrinks to the accommodating groove 66; then the clamping block 61 moves down to the locking groove 62 and is located below the abutment plate 67, and the abutment plate 67 loses the extrusion force of the clamping block 61 and contacts the spring rod. The clamping block 61 is reset under the action of 68, so that the abutment plate 67 abuts against the upper end of the clamping block 61 and limits and fixes it, and at this time, the clamping block 61 drives the force-bearing plate 63 to move downward through the connecting plate 65 and abut against the inner bottom wall of the through hole 11, so that the abutment plate 67 can limit and fix the force-bearing plate 63 by limiting the clamping block 61, and then the force-bearing plate 63 is pressed and fixed to the bottom support foot of the compressor body 1, so that the clamping sleeve 5 and the positioning plate 4 can be used to fix the bottom support foot of the compressor body 1 in all directions, so that the compressor body 1 can be quickly installed and the stability of the compressor body 1 during use can be ensured.

[0055] When the compressor body 1 needs to be removed, the two abutment plates 67 are controlled to move away from each other and shrink into the accommodating groove 66, so as to release the limiting effect of the abutment plate 67 on the clamping block 61. Then, the force-bearing plate 63 drives the connecting plate 65 and the clamping block 61 to move up and reset as a whole under the action of the contraction spring 64, so as to release the limiting effect on the bottom support foot of the compressor body 1. Then, the compressor body 1 can be pushed away from the clamping sleeve 5 to realize the quick disassembly of the compressor body 1. The operation is convenient and there is no need to use more cumbersome bolts for fixing and disassembly. It can effectively improve the disassembly and assembly efficiency of the compressor body 1, thereby reducing the time required for maintenance.

[0056] Reference Figure 6 As shown, in order to facilitate the control of the two abutment plates 67 to quickly open so as to release the limiting effect on the clamping block 61, in the present embodiment, the locking unit 6 also includes two linkage rods 69 respectively installed at the two ends of the abutment plates 67, and a rotating shaft 70 located on the opposite sides of the two linkage rods 69 is rotatably installed inside the support plate 2, and a cam block 71 is sleeved on the outer wall of the rotating shaft 70, and the cam block 71 rotates and abuts against the opposite sides of the two linkage rods 69; a driving shaft 72 is rotatably installed on the upper end of the support plate 2, and belts 73 are respectively sleeved between the driving shaft 72 and the two rotating shafts 70, and a plurality of limiting shafts 74 for tensioning the belts 73 are rotatably installed inside the support plate 2, and the belts 73 can be supported by the limiting shafts 74, and a joystick 75 is sleeved on the upper end of the driving shaft 72.

[0057] It should be noted that the cam block 71 provided in this embodiment has two protrusions and two base circular portions, the two protrusions and the two base circular portions are more distributed, and the distance between the outer walls of the two protrusions and the axis of the rotating shaft 70 is greater than the distance between the outer wall of the base circular portion and the axis of the rotating shaft 70; in the initial state, the two base circular portions of the cam block 71 are in contact with the linkage rod 69, at which time the distance between the two linkage rods 69 is the minimum, and the two abutment plates 67 are in contact with each other.

[0058] During the specific implementation process, when the compressor body 1 is removed, it is necessary to first move the clamping block 61 upward from the lower ends of the two abutment plates 67. Specifically, the driving shaft 72 is controlled to rotate by the operating lever 75, and the driving shaft 72 drives the rotating shaft 70 and the cam block 71 to rotate synchronously through the belt 73, and controls the cam block 71 to rotate 90 degrees, so that the two protrusions of the cam block 71 contact the linkage rod 69 and push it to the side away from the rotating shaft 70. The linkage rod 69 drives the abutment plate 67 to move synchronously and releases the limiting effect on the clamping block 61, so that the clamping block 61 can be smoothly moved up and reset, thereby quickly releasing the limiting fixation of the bottom support foot of the compressor body 1, thereby ensuring that the compressor body 1 can be quickly disassembled.

[0059] Subsequently, the operating lever 75 is used to drive the driving shaft 72 to rotate in the opposite direction and reset, so that the driving shaft 72 drives the rotating shaft 70 and the cam block 71 to rotate synchronously, thereby controlling the rotation and reset of the cam block 71, and then releasing the ejection force of the cam block 71 on the linkage rod 69 and the abutment plate 67, so that the abutment plate 67 extends from the accommodating groove 66 under the action of the top contact spring rod 68 and resets to the initial state.

[0060] Reference Figure 7 As shown, in order to prevent the drive shaft 72 from rotating arbitrarily and driving the cam block 71 to rotate synchronously, causing the two abutment plates 67 to be unable to reset and unable to limit the clamping block 61, in this embodiment, a connecting hole 76 is opened on the operating rod 75, and a limiting block 77 located on one side of the drive shaft 72 is installed on the upper end of the supporting plate 2, and the limiting block 77 cooperates with the connecting hole 76, and an elastic telescopic rod 78 is provided between the lower end of the limiting block 77 and the supporting plate 2; the elastic telescopic rod 78 can apply an upward extending force to the limiting block 77, so that the limiting block 77 is in an initial state. The cam 71 is in the form of a plurality of locking plates 76 that are provided at the bottom of the cam face 72 and a plurality of locking plates 76 are provided at the bottom of the cam face 72. The cam face 71 is provided with a plurality of locking plates 76 that are provided at the bottom of the cam face 72.

[0061] Reference Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in order to facilitate quick maintenance of the compressor body 1, in the present embodiment, the compressor body 1 can be maintained without disassembling it, specifically, the supporting plate 2 is composed of a base plate 21 and a movable plate 22, wherein the base plate 21 is arranged on the mounting platform 3, a sliding groove is provided at the upper end of the base plate 21, and a movable plate 22 is slidably docked inside the sliding groove, and the compressor body 1 is detachably mounted on the upper end of the movable plate 22, and controlling the movable plate 22 to move along the sliding groove can drive the compressor body 1 to move synchronously, thereby facilitating the compressor body 1 to be quickly removed from the mounting platform 3, but the compressor body 1 does not need to be removed from the mounting platform 3, so as to facilitate local maintenance thereof, which not only reduces the workload but also improves the maintenance efficiency, and a fixing component 23 for locking and limiting the movable plate 22 is installed between the movable plate 22 and the base plate 21.

[0062] Furthermore, in order to prevent the movable plate 22 from sliding randomly and causing the compressor body 1 to move randomly, in the present embodiment, the fixing assembly 23 includes an auxiliary slide groove 231, and two auxiliary slide grooves 231 are symmetrically provided inside the movable plate 22 along its width direction, and two through holes are symmetrically provided on the side of the auxiliary slide groove 231 away from the middle of the movable plate 22 along the length direction, and an insertion rod 232 is slidably passed through the through hole, and a limiting hole corresponding to the position of the through hole and cooperating with the insertion rod 232 is provided on the side of the base plate 21 close to the movable plate 22; the through hole is provided with docking grooves 233 on the upper and lower sides, and two pads 234 slidably arranged in the docking grooves 233 are symmetrically installed on the outer wall of the insertion rod 232, and a supporting spring 235 is installed between the pad 234 and the docking groove 233, and the supporting spring 235 always applies a driving force to the pad 234 pointing to the side of the auxiliary slide groove 231, so that the pad 234 drives the insertion rod 232 to retract into the through hole in the initial state.

[0063] Furthermore, in this embodiment, a reciprocating plate 236 is slidably arranged in the auxiliary slide groove 231, and two extrusion blocks 237 corresponding to the position of the insertion rod 232 are installed on the side of the reciprocating plate 236 close to the through hole, and the extrusion block 237 is gradually inclined toward the middle part away from the reciprocating plate 236. A linkage plate 238 is installed on the side of the middle of the reciprocating plate 236 close to the through hole, and two fixed plates 239 are installed on the inner wall of the auxiliary slide groove 231. The linkage plate 238 and the two fixed plates 239 are symmetrically distributed along the linkage plate 238. A return spring 240 is installed between the linkage plate 238, and the return spring 240 applies a pushing force to the linkage plate 238, and the pushing forces on both sides of the linkage plate 238 are equal. Therefore, the linkage plate 238 drives the reciprocating plate 236 to be located in the middle of the auxiliary slide groove 231 in the initial state, and the reciprocating plate 236 drives the extrusion block 237 to abut against the insertion rod 232, so that the insertion rod 232 extends out of the through hole and then inserts into the limiting hole. The base plate 21 and the movable plate 22 can be limited and fixed by the cooperation between the insertion rod 232 and the limiting hole (in Fig. 9 ), to prevent the movable plate 22 from moving randomly and causing adverse effects on the compressor body 1.

[0064] Furthermore, in this embodiment, a pull rope 241 is installed at the same end of the two reciprocating plates 236. After the two pull ropes 241 pass through the movable plate 22, a movable handle 242 is installed together. A positioning frame 243 located outside the movable handle 242 is installed at both ends of the movable plate 22.

[0065] During the specific implementation process, when local maintenance of the compressor body 1 is required, the staff presses the movable handle 242 to the side close to the positioning frame 243, and the movable handle 242 drives the reciprocating plate 236 to move synchronously through the pull rope 241, and the reciprocating plate 236 drives the extrusion block 237 to be staggered with the insertion rod 232, so that the insertion rod 232 can be reset and pulled out from the limiting hole under the action of the pad 234 and the support spring 235, thereby releasing the limiting effect between the base plate 21 and the movable plate 22; then the movable plate 22 is pushed out from the base plate 21 through the positioning frame 243, so as to expose the maintenance part of the compressor body 1, so that local maintenance can be performed on it.

[0066] After the maintenance of the compressor body 1 is completed, the movable handle 242 is pressed to retract the insertion rod 232, and then the movable plate 22 is pushed back to its original position through the positioning frame 243, and then the movable handle 242 is released, so that the reciprocating plate 236 is reset under the action of the linkage plate 238 and the reset spring 240 and drives the extrusion block 237 to abut against the insertion rod 232, so as to restore the connection between the insertion rod 232 and the limiting hole and the fixation between the base plate 21 and the movable plate 22. It is not only convenient to operate, but also can reduce the workload and improve the maintenance efficiency.

[0067] It should be noted that the first anti-slip group and the second anti-slip group are symmetrically arranged on the opposite sides of the base plate 21 and the movable plate 22 along the length direction. The first anti-slip group includes a blocking frame 244 installed on the upper end of the base plate 21 and a displacement frame 245 arranged on the upper end of the movable plate 22. The second anti-slip group includes a shifting frame 246 installed on the upper end of the base plate 21 and an execution frame 247 arranged on the upper end of the movable plate 22. A clearance groove is provided on the side of the lower half of the blocking frame 244 close to the movable plate 22 to facilitate the displacement frame 245 to pass through. The height of the upper half of the blocking frame 244 is greater than the height of the execution frame 247. The execution frame 247 is an L-shaped structure. The height of the shifting frame 246 is less than the height of the horizontal section of the execution frame 247, and the height of the shifting frame 246 is greater than the height of the displacement frame 245.

[0068] The first anti-slip group and the second anti-slip group can prevent the movable plate 22 from being pushed out too far and causing the movable plate 22 to detach from the base plate 21. Specifically, the blocking frame 244 can block and limit the execution frame 247, and the shifting frame 246 can block and limit the displacement frame 245, so as to effectively limit the moving distance of the movable plate 22 to both sides and prevent the movable plate 22 from detaching from the base plate 21.

[0069] During operation: Step 1: First, place the compressor body 1 on the supporting plate 2, and then insert one of the bottom legs of the compressor body 1 into the clamping sleeve 5. The through hole 11 of the other bottom leg of the compressor body 1 corresponds to the position of the locking groove 62. At this time, the force-bearing plate 63 is pressed, and the force-bearing plate 63 drives the clamping block 61 to move down into the locking groove 62 through the connecting plate 65 and is located below the abutment plate 67. The abutment plate 67 abuts against the upper end of the clamping block 61 and limits and fixes it; the force-bearing plate 63 can be limited and fixed by limiting the clamping block 61 through the abutment plate 67, and then the bottom leg of the compressor body 1 can be pressed and fixed through the force-bearing plate 63, so that the bottom leg of the compressor body 1 can be fixed in all directions in cooperation with the clamping sleeve 5 and the positioning plate 4, so that the compressor body 1 can be quickly installed and the stability of the compressor body 1 during use can be ensured.

[0070] The second step: when the compressor body 1 needs to be removed, first disconnect it from the pipes and other connecting parts on the mounting platform 3, and then control the rotation of the drive shaft 72 through the operating lever 75. The drive shaft 72 drives the rotating shaft 70 and the cam block 71 to rotate synchronously through the belt 73, and controls the cam block 71 to rotate 90 degrees, so that the two protrusions of the cam block 71 contact the linkage rod 69 and push it to the side away from the rotating shaft 70, and the linkage rod 69 drives the abutment plate 67 to move synchronously and release the limiting effect on the clamping block 61; then the force plate 63 drives the connecting plate 65 and the clamping block 61 to move up and reset as a whole under the action of the contraction spring 64, so as to release the limiting effect on the bottom support foot of the compressor body 1, and then the compressor body 1 is pushed out to the side away from the clamping sleeve 5 to realize the quick disassembly of the compressor body 1, which is convenient to operate.

[0071] Step 3: When local maintenance of the compressor body 1 is required, the staff presses the movable handle 242 toward the side close to the positioning frame 243. The movable handle 242 drives the reciprocating plate 236 to move synchronously through the pull rope 241. The reciprocating plate 236 drives the extrusion block 237 to be staggered with the insertion rod 232, so that the insertion rod 232 can be reset and pulled out from the limiting hole under the action of the pad 234 and the support spring 235, thereby releasing the limiting effect between the base plate 21 and the movable plate 22; then the movable plate 22 is pushed out from the base plate 21 through the positioning frame 243, so as to expose the part of the compressor body 1 to be maintained, so that local maintenance can be performed on it.

[0072] After the maintenance of the compressor body 1 is completed, the movable handle 242 is pressed to retract the insertion rod 232, and then the movable plate 22 is pushed back to its original position through the positioning frame 243, and then the movable handle 242 is released, so that the reciprocating plate 236 is reset under the action of the linkage plate 238 and the reset spring 240 and drives the extrusion block 237 to abut against the insertion rod 232, so as to restore the connection between the insertion rod 232 and the limiting hole and the fixation between the base plate 21 and the movable plate 22. It is not only convenient to operate, but also can reduce the workload and improve the maintenance efficiency.

[0073] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
