Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an adjustable multi-angle charging and discharging device for compressor operation testing. Background Technology

[0002] During the assembly process, in order to ensure the dynamic stability of the compressor rotor and determine whether the performance of the assembled compressor transmission system meets the factory requirements, each compressor needs to undergo an operation test. This involves two oil injections to simulate the operation of the compressor during use and to determine whether the compressor performance is up to standard.

[0003] During operational testing, gas needs to be charged into the compressor, and the compressor's discharge pressure and holding pressure must be measured simultaneously. Under the set speed, operating time, and holding time, the discharge pressure must reach the calibrated value. In related technologies, the charging and discharging mechanism is directly mounted on the top of the frame and is used for charging by pressing down. However, during use, due to the tricky positions and angles of the air inlet and outlet of some irregularly shaped compressors, it is difficult for the nozzle of the charging and discharging mechanism to accurately align with the compressor's air inlet and outlet, affecting the sealing effect and consequently the accuracy of the subsequent operational test results.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figures 1 to 6 The adjustable multi-angle charging and discharging device for compressor operation testing shown includes:

[0034] The support mechanism 10 is fixedly installed on the frame. As the foundation of the entire device, the support mechanism 10 provides stable support for the mounting frame 20 and the inflation and deflation mechanism 30, ensuring the stability and reliability of the entire device during operation.

[0035] The mounting bracket 20, mounted on top of the support mechanism 10, provides special installation and adjustment space for the inflation / deflation mechanism 30;

[0036] The charging and discharging mechanism 30 is movably connected to one side of the mounting bracket 20 and is used to dock with the compressor and perform charging and discharging operations;

[0037] The adjustment mechanism 40 is assembled on one side of the top of the support mechanism 10 and fixedly connected to one end of the mounting frame 20. It is used to drive the mounting frame 20 and the inflation / deflation mechanism 30 to move in the horizontal direction, thereby realizing the flexible adjustment of the inflation / deflation mechanism 30 in the horizontal position.

[0038] The mounting frame 20 has an arc-shaped plate 21. A toothed structure is evenly distributed along the length of one side of the arc-shaped plate 21. An adjustable component 31 is provided on the side of the inflation / deflation mechanism 30 facing the arc-shaped plate 21. The toothed structure of the arc-shaped plate 21 is engaged in the space formed by the inflation / deflation mechanism 30 and the adjustable component 31. The inflation / deflation mechanism 30 includes an air nozzle 32, an air pipe 33, a connecting plate 34, and a telescopic drive component 35. The air nozzle 32 is provided on the side where the compressor is located. The air pipe 33 is fixedly installed on the connecting plate 34 and one end is connected to the air nozzle 32. The telescopic drive component 35 is connected to the adjustable component 31 and its actuating end is fixedly connected to the connecting plate 34.

[0039] This invention allows for arbitrary adjustment of the position of the charging / discharging mechanism 30 by mounting the charging / discharging mechanism 30 on the mounting frame 20 and changing the orientation and height of the mounting frame 20 through the support mechanism 10 and the adjustment mechanism 40. Through the cooperation between the arc-shaped plate 21 and the adjustable component 31, the orientation and angle of the charging / discharging mechanism 30 on the mounting frame 20 can be flexibly adjusted, thereby changing the orientation of the air nozzle 32 on the charging / discharging mechanism 30 to adapt to the compressor inlet and outlet at different positions and angles. This ensures a sealing effect, improves the accuracy of operational test results, and adapts to compressors of different models and shapes, expanding the scope of application of the device and improving the versatility of the equipment.

[0040] Specifically, when using the charging / discharging mechanism 30, firstly, the charging / discharging mechanism 30 is assembled onto the mounting bracket 20. The supporting mechanism 10 sets the charging / discharging mechanism 30 at a suitable height, with the nozzle 32 facing the compressor. Based on the position and angle of the compressor's inlet or outlet, the adjusting mechanism 40 drives the mounting bracket 20 and the charging / discharging mechanism 30 to move horizontally, bringing the approximate position of the charging / discharging mechanism 30 close to the compressor interface. Simultaneously, the adjustable component 31 engages with the toothed structure of the arc-shaped plate 21 of the mounting bracket 20 to adjust the angle and position of the charging / discharging mechanism 30. Once the nozzle 32 is accurately aligned with the compressor's inlet or outlet, the telescopic drive component 35 drives the charging / discharging mechanism 30 to extend or retract towards the compressor, ensuring a tight connection between the nozzle 32 and the compressor interface and guaranteeing a seal. During the operational test, gas is charged into the compressor through the charging / discharging mechanism 30, and the compressor's discharge pressure and holding pressure are simultaneously monitored to determine if the compressor's performance is up to standard.

[0041] Based on the above embodiments, the telescopic drive 35 and the adjustable component 31 are respectively disposed on both sides of the fixed plate. The adjustable component 31 includes an adjusting plate 311, a support rod 312 and a rotating head 313. The arc-shaped plate 21 has an arc-shaped track 21a on the side facing the inflation / deflation mechanism 30. The fixed plate is pressed against the side of the arc-shaped plate with the track 21a. One end of the adjusting plate 311 is fixedly connected to the fixed plate. Two support rods 312 are provided. One end of each support rod 312 is connected to the other end of the adjusting plate 311. The other end of each support rod 312 is equipped with a rotating head 313. The rotating head 313 is rolled and fitted against the other side of the arc-shaped plate.

[0042] Specifically, the fixed plate serves as a support and connector, integrating the telescopic drive component 35 and the adjustable component 31 into one unit. During adjustment, the adjusting plate 311 drives the support rod 312 and the rotating head 313 to move along the track 21a of the arc-shaped plate 21 through external operation. Whether manually or electrically driven, the rotating head 313 rolls and adheres to the arc-shaped plate 21, allowing the inflation / deflation mechanism 30 to adjust its angle around the curvature of the arc-shaped plate 21. During this process, the track 21a of the arc-shaped plate 21 provides trajectory guidance for the movement of the adjustable component 31, enabling precise adjustment of the angle of the inflation / deflation mechanism 30, ensuring the tightness and stability of the entire structure, and preventing loosening or displacement during adjustment.

[0043] Based on the above embodiment, two arc-shaped plates 21 are arranged in parallel. The same end of the two arc-shaped plates 21 is fixedly connected by a mounting block 22. Multiple support columns 23 are evenly distributed between the two arc-shaped plates 21. Both ends of each support column 23 are fixedly connected to the opposite sides of the two arc-shaped plates 21.

[0044] The two arc-shaped plates 21 can effectively distribute and bear certain pressure and torque, thereby significantly enhancing the overall rigidity of the mounting frame 20 and preventing structural deformation. The mounting block 22 not only strengthens the structural integrity between the two arc-shaped plates 21, but also provides a stable support point for the entire mounting frame 20, so that the arc-shaped plates 21 can evenly transmit the force to the support mechanism 10 when under stress, avoiding local stress concentration. Multiple pillars 23 together with the arc-shaped plates 21 form a frame structure, further enhancing the stability of the overall structure, so that the entire device can maintain good performance and reliability during long-term use and extend the service life of the device.

[0045] Based on the above embodiments, the mounting frame 20 also includes two sets of sliding components 24 respectively disposed between the two mounting blocks 22 and the support mechanism 10. Each set of sliding components 24 includes a fixed block 241, a slider 242 and a slide rail 243. The fixed block 241 is fixedly connected to one side of the top of the support mechanism 10. The slide rail 243 is fixedly disposed on the top of the fixed block 241. One side of the slider 242 is fixedly connected to the side of the mounting block 22 away from the arc-shaped plate 21, and the other side is slidably connected to the slide rail 243.

[0046] The fixed block 241 provides a stable installation position for the slide rail 243, ensuring the overall stability of the sliding assembly 24; the slide rail 243 provides a sliding track 21a for the slider 242, guiding the slider 242 to move horizontally along a predetermined path, ensuring the smoothness and straightness of the movement process; the slider 242 slides on the slide rail 243, driving the mounting block 22 and the entire mounting frame 20 to move horizontally, thereby adjusting the horizontal position of the inflation / deflation mechanism 30.

[0047] Based on the above embodiments, the adjustment mechanism 40 includes a first seat 41, a second seat 42, a connecting block 43, an adjustment rod 44, and a handwheel 45. The first seat 41 and the second seat 42 are respectively connected to both ends of the fixing block 241. The top of the connecting block 43 is fixedly connected to the side of the mounting block 22. The adjustment rod 44 passes through the first seat 41, the connecting block 43, and the second seat 42 in sequence. The handwheel 45 is assembled at the end of the adjustment rod 44 located outside the first seat 41.

[0048] During the process of adjusting the horizontal position of the mounting bracket 20 through the adjusting mechanism 40, the handwheel 45 and the adjusting rod 44 can be used to make fine adjustments, precisely control the moving distance of the mounting bracket 20, and improve the accuracy of the connection between the charging and discharging mechanism 30 and the compressor interface. Specifically, manually rotating the handwheel 45 drives the adjusting rod 44 to rotate. Due to the cooperation between the adjusting rod 44 and the connecting block 43, the rotational motion is converted into the linear motion of the connecting block 43 along the axis of the adjusting rod 44. The fixed connection between the connecting block 43 and the mounting block 22 drives the mounting bracket 20 and the charging and discharging mechanism 30 to move in the horizontal direction.

[0049] Based on the above embodiment, a stop ring 46 is also sleeved on the adjusting rod 44. The stop ring 46 is located between the first seat 41 and the handwheel 45, and a lock head 46a is rotatably connected to the outer shaft surface.

[0050] The stop ring 46 can limit the movement range of the adjusting rod 44, preventing the adjusting rod 44 from moving excessively during rotation, thereby preventing the mounting bracket 20 and the inflation / deflation mechanism 30 from exceeding their designed adjustment range. After adjustment, the adjusting rod 44 can be locked by rotating the locking head 46a with the outer shaft surface of the stop ring 46, preventing the adjusting rod 44 from loosening or displacing due to vibration or other external forces during operation test, thereby ensuring that the position and angle of the inflation / deflation mechanism 30 remain stable during the test.

[0051] Based on the above embodiments, the connecting plate 34 includes a first plate 341, a second plate 342, and a third plate 343; the actuator of the telescopic drive member 35 is fixedly connected to one side of the first plate 341; a first adjusting member 341a is provided at the end of the first plate 341; the first adjusting member 341a is fixedly connected to the second plate 342; the second plate 342 is slidably connected to the first plate 341; a second adjusting member 342a is provided at the end of the second plate 342; the second adjusting member 342a is fixedly connected to the third plate 343; the third plate 343 is slidably connected to the second plate 342; the sliding directions of the second plate 342 and the third plate 343 are perpendicular to each other; and the air pipe 33 is fixedly installed on the third plate 343.

[0052] Through the sliding connection between the second plate 342 and the third plate 343, the nozzle 32 can achieve precise and fine adjustment of its position in two mutually perpendicular directions. During adjustment, the position of the second plate 342 can be changed by the first adjusting member 341a, and the second adjusting member 342a can make the nozzle 32 more accurately aligned with the air inlet or outlet of the compressor. Even when facing complex interfaces, it can maintain good sealing and docking accuracy, and also enhance the flexibility and adaptability of the device, so that it can better meet the operational test requirements of different compressors.

[0053] Based on the above embodiments, a first adjustment groove 341b is provided on the side of the first plate 341 facing the second plate 342, and the second plate 342 protrudes in the middle of the side facing the first plate 341 and is slidably disposed in the first adjustment groove 341b; a second adjustment groove 342b is provided on the side of the second plate 342 facing the third plate 343, and the third plate 343 protrudes in the middle of the side facing the second plate 342 and is slidably disposed in the second adjustment groove 342b; the first adjustment groove 341b and the second adjustment groove 342b are arranged perpendicular to each other.

[0054] By opening mutually perpendicular adjustment slots on the connecting plate 34 and setting sliding connection protrusions between each plate, the inflation and deflation mechanism 30 can achieve flexible position adjustment in two vertical directions while ensuring the connection stability between the air nozzle 32, air pipe 33 and telescopic drive 35, preventing shaking during position and angle adjustment, and ensuring stability.

[0055] Based on the above embodiments, the support mechanism 10 includes a base plate 11, guide blocks 12 and guide posts 13. The base plate 11 is fixedly connected to the bottom of the frame. Four guide blocks 12 are provided, located at the four corners of the base plate 11 respectively. Each guide block 12 is provided with a guide post 13. The other end of the guide post 13 is fixedly connected to the bottom of the mounting frame 20.

[0056] The fixed connection between the base plate 11 and the bottom of the frame provides a stable foundation for the entire device, ensuring that the device will not shake or shift during operation. The cooperation between the guide block 12 and the guide column 13 provides precise guidance for the lifting or position adjustment of the mounting frame 20. Furthermore, the linear motion characteristics of the guide column 13 enable the mounting frame 20 to move vertically and smoothly along a predetermined path, improving the adjustment accuracy and thus enhancing the movement accuracy and stability of the mounting frame 20.

[0057] Based on the above embodiment, a bracket 14 is also provided between the two guide blocks 12 on the same side. The bracket 14 includes a top block 141, an upper top plate 142 and a lower top plate 143. The top block 141 is fixedly disposed between the upper top plate 142 and the lower top plate 143. The lower top plate 143 is fixedly connected to the bottom plate 11, and the upper top plate 142 is fixedly connected to the top of the frame.

[0058] The bracket 14 enhances the structural stability between the two guide blocks 12 on the same side. At the same time, it is fixedly connected to the top of the frame through the upper top plate 142, which can bear part of the load, improve the load-bearing capacity of the support mechanism 10, provide additional protection for the smooth movement of the mounting frame 20, and further ensure the safety of the position and angle adjustment process.
