Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a test device for the shaft power of an air compressor. Background Technology

[0002] Air compressors are widely used in various industries such as machinery manufacturing, mining and metallurgy, and construction materials. Their core function is to convert mechanical energy into gas pressure energy, providing stable compressed air power for various production processes. To reduce energy consumption during air compressor operation, intelligent starter motors are generally used for driving. The energy-saving effect and operating performance of energy-saving starter motors ultimately need to be verified through the actual operating parameters of the air compressor. Among them, the air compressor shaft power is a core key indicator for evaluating the energy consumption level, energy-saving effect, and operating efficiency of the air compressor. Air compressor shaft power refers to the actual power transmitted by the motor to the air compressor main shaft. Its value directly reflects the load state and energy loss of the air compressor, and is also the core basis for judging the compatibility of the energy-saving starter motor with the air compressor and verifying the effect of energy-saving transformation. The existing general version uses an intelligent drive device to simulate the operation of an intelligent starter motor to detect the dynamic power movement state of the air compressor shaft, thereby determining whether the air compressor meets the requirements.

[0003] Most existing testing devices cannot flexibly adjust the relative position between the air compressor and the test motor, resulting in a fixed belt tension. This means that shaft power testing can only be performed under a single tension condition. However, in actual industrial scenarios, the belt of the air compressor will loosen or tighten to varying degrees due to wear, temperature changes, etc. Existing devices cannot simulate this dynamic working condition, resulting in biased test data that cannot truly reflect the shaft power of the air compressor under different load conditions, leading to low accuracy of the test results. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an air compressor shaft power testing device.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an air compressor shaft power testing device, comprising a housing and a detection motor fixed inside the housing and capable of intelligent driving, wherein a main pulley is fixedly sleeved on the output end of the detection motor, and an adjustable mounting bracket is provided on the top of the housing, wherein an air compressor is detachably connected to the top of the mounting bracket, and a driven pulley is detachably connected to the drive shaft of the air compressor, wherein the output end of the air compressor drive motor rotates through a belt connecting the main pulley and the driven pulley.

[0006] By adopting the above technical solution, the torque detection device is first connected to the driven pulley. Then, the detection motor drives the main pulley to rotate. Under the transmission between the belt and the driven pulley, the drive shaft of the air compressor is driven to rotate. At the same time, the torque detection device measures the torque generated when the driven pulley rotates and can determine the operating power of the air compressor according to the power calculation formula, so as to judge the energy consumption level, energy saving effect and operating efficiency of the air compressor. In addition, by moving the position of the mounting bracket on the housing, the position of the air compressor on the housing is changed, thereby changing the distance between the driven pulley and the main pulley. The operating power of the air compressor under various belt tension states can be realized, thus realizing dynamic testing of the air compressor and improving the accuracy of the device detection.

[0007] Furthermore, the housing is provided with a fixing mechanism, the mounting bracket is provided with a through hole, the top of the housing is provided with multiple threaded grooves, the fixing mechanism includes a bolt passing through the through hole and threadedly connected to the corresponding threaded groove, and a limiting block fixed to the upper end of the bolt and coaxially arranged with the bolt. The bottom of the limiting block abuts against the surface of the mounting bracket, and the top of the limiting block is provided with an auxiliary groove of regular hexagonal structure for a hexagonal wrench to pass through.

[0008] By adopting the above technical solution, the rotating limit block drives the bolt to rotate until the bolt separates from the corresponding thread groove. Then, the mounting bracket is moved laterally until the through hole moves above other thread grooves, and the bolt is threadedly connected to the corresponding thread groove at this time, thus realizing the fastening operation of the mounting bracket.

[0009] Furthermore, the housing is provided with a displacement component and a detection mechanism for detecting the air compressor. The mounting frame is a hollow structure with openings at the top and bottom. A lifting mechanism is provided on the mounting frame, and the air compressor is mounted on the lifting mechanism. The lifting mechanism includes a limiting component, which includes a lifting shell slidably disposed within the mounting frame, an annular plate fixed to the top of the lifting shell, sliding plates fixed to the side walls on both sides of the lifting shell, and an annular frame fixed to the side wall of the mounting frame. The base of the air compressor passes through the annular plate and slides in engagement. Sliding holes that slide in engagement with the sliding plates are provided through the side wall of the mounting frame. The number of sliding holes, the number of sliding plates, and the number of annular frames are all equal and their positions correspond one-to-one. The sliding plates extend into the annular frame and slide in engagement with the annular frame. The lifting mechanism also includes a lifting component for driving the lifting shell to rise and fall, and a clamping component for clamping the base of the air compressor.

[0010] By adopting the above technical solution, the lifting assembly is operated to drive the lifting shell to rise and fall, thereby driving the annular plate fixed to the lifting shell and the air compressor slidably connected to the annular plate to rise and fall, thereby changing the distance between the pulley and the main pulley, thus changing the belt tension. In addition, the distance between the pulley and the main pulley is adjusted to be less than the vertical length of the belt, so that the belt can be connected or separated from the pulley and the main pulley, which facilitates the use of the device.

[0011] Furthermore, the lifting assembly includes two threaded columns that pass through the bottom of the ring frame and are rotatably connected to the ring frame, a drive housing fixed to the bottom of the ring frame, a worm gear fixedly sleeved at the lower end of the threaded columns and located inside the drive housing, a worm gear rotatably installed inside the drive housing and meshing with the worm gear, and a lifting motor fixed to the drive housing and driving the worm gear to rotate. The threaded columns pass through the top of the sliding plate and are threadedly connected to the sliding plate. The number of threaded columns is equal to the number of worm gears and their positions correspond one-to-one. The number of lifting assemblies is equal to the number of sliding plates and their positions correspond one-to-one.

[0012] By adopting the above technical solution, when the lifting motor is working, it drives the worm to rotate, which in turn drives the worm wheel meshing with the worm and the threaded column fixedly connected to the worm wheel to rotate synchronously. This causes the sliding plate threadedly connected to the threaded column and the lifting shell fixed to the sliding plate to rise and fall, thereby changing the height of the air compressor.

[0013] Furthermore, the clamping assembly includes two movable plates slidably disposed within the lifting housing, a crossbar fixed within the lifting housing and slidably engaged with both movable plates, a bidirectional screw penetrating the side wall of the lifting housing and rotatably connected to the lifting housing, and a clamping plate fixed to the top of the movable plates and having an L-shaped structure. The bidirectional screw is provided with two sections of threads with opposite directions and equal pitch. The two movable plates are respectively disposed on the two sections of threads and threadedly connected. The top of the lifting housing is provided with a mounting hole through which the clamping plate passes and slidably engages. The horizontal section of the clamping plate penetrates the side wall of the annular plate and slidably engages. The side wall of the horizontal section of the clamping plate near the air compressor abuts against the side wall of the air compressor base. The number of clamping plates, the number of mounting holes, and the number of movable plates are all equal and their positions correspond one-to-one. The lifting mechanism also includes a rotating assembly for driving the bidirectional screw to rotate.

[0014] By adopting the above technical solution, the rotating component drives the bidirectional screw to rotate. Due to the good limiting effect of the crossbar, the bidirectional screw is provided with two sections of threads with opposite directions and equal pitch. The two moving plates are respectively set on the two sections of threads and threadedly connected. This allows the two moving plates and the two clamping plates fixed to the two moving plates to move away from or towards each other, thereby separating or sticking the clamping plates to the surface of the air compressor base. This enables the operation of loosening or clamping the air compressor. The setting of the clamping component improves the stability of the air compressor during testing.

[0015] Furthermore, the rotating assembly includes baffles fixed to the side walls on both sides of the housing, a limiting plate fixed to the sliding plate, a rotating rack slidably disposed on the baffles, a connecting rod fixed to the bidirectional screw and coaxially disposed with the bidirectional screw, and a rotating gear fixedly sleeved on the connecting rod and meshing with the rotating rack. The limiting plate is slidably engaged with the rotating rack, and the rotating rack is slidably connected to the baffles through a guide rod, a vertical hole, and a connecting block, so that the rotating rack can only slide up and down along the surface of the baffles.

[0016] By adopting the above technical solution, when the sliding plate rises and falls, it drives the lifting housing connected to the sliding plate, the bidirectional screw connected to the lifting housing, the connecting rod connected to the bidirectional screw, the rotating gear fixed to the connecting rod, the limiting plate fixed to the sliding plate, and the rotating rack slidably connected to the limiting plate to rise and fall. Furthermore, the operating displacement component drives the mounting frame to move, which causes the lifting housing connected to the mounting frame, the bidirectional screw connected to the lifting housing, the connecting rod connected to the bidirectional screw, and the rotating gear fixed to the connecting rod to rotate. Since the rotating gear meshes with the rotating rack, it drives the rotating gear, the connecting rod fixed to the rotating gear, and the bidirectional screw fixed to the connecting rod to rotate, thereby realizing the clamping or loosening operation of the air compressor.

[0017] Furthermore, the detection mechanism includes a detection component and a transmission component. The detection component includes a mounting plate fixed to the housing, a horizontal plate slidably disposed on the mounting plate, a torque sensor fixed to the top of the horizontal plate, and a hydraulic push rod fixed to the mounting plate. The push rod end of the hydraulic push rod is fixedly connected to the horizontal plate. The transmission component includes a transmission rod fixed to the rotation detection end of the torque sensor, a connecting plate fixedly sleeved on the transmission rod, a main synchronizing ring disposed on the side of the connecting plate away from the transmission rod, and a secondary synchronizing ring fixedly sleeved on the secondary pulley and meshing with the main synchronizing ring.

[0018] By adopting the above technical solution, when the pulley rotates, it drives the driven synchronizing ring fixed to the pulley, the main synchronizing ring meshing with the driven synchronizing ring, the connecting disc connected to the main synchronizing ring, the transmission rod fixed to the connecting disc, and the rotation detection end of the torque sensor to rotate. The torque sensor can then detect the drive shaft connected to the pulley. Furthermore, when the hydraulic push rod operates, its push rod end extends and retracts, which drives the horizontal plate fixed to the hydraulic push rod and the torque sensor fixed to the horizontal plate to rise and fall, coordinating with the lifting and lowering operation of the air compressor, thereby ensuring the normal detection operation of the device.

[0019] Furthermore, the displacement assembly includes a movable shell fixed to the bottom of the mounting bracket, a limiting hole is provided through the side wall of the movable shell, and the displacement assembly also includes a first rack fixed to the top of the shell and slidingly engaged with the limiting hole, a displacement motor fixed inside the movable shell, a drive rod fixedly sleeved on the output end of the displacement motor, and a displacement gear fixedly sleeved on the drive rod and meshing with the first rack.

[0020] By adopting the above technical solution, the displacement motor operates, driving the drive rod fixed to the output end of the displacement motor and the displacement gear fixed to the drive rod to rotate. Since the displacement gear meshes with the first rack, the displacement gear, the drive rod fixed to the displacement gear, the displacement motor fixed to the drive rod, the movable housing fixed to the displacement motor, the mounting bracket fixed to the movable housing, the air compressor connected to the mounting bracket, the driven pulley connected to the air compressor, and the driven synchronizing ring fixed to the driven pulley can all move. This allows for normal separation or engagement of the driven synchronizing ring, and also enables the loosening or clamping of the air compressor base, facilitating the use of the device.

[0021] Furthermore, the main synchronizing ring is rotatably mounted on the connecting plate and coaxially arranged with the connecting plate. An arc-shaped hole is provided through the side wall of the connecting plate. The detection mechanism also includes a buffer assembly, which includes an arc-shaped slider fixed to the main synchronizing ring and slidingly engaged with the arc-shaped hole, an arc-shaped rod fixed inside the arc-shaped hole and slidingly engaged with the arc-shaped slider, and an arc-shaped spring fixed to the arc-shaped slider and the inner side wall of the arc-shaped hole.

[0022] By adopting the above technical solution, when the slave synchronizing ring moves closer to the master synchronizing ring, and the transmission teeth of the slave synchronizing ring contact the transmission teeth of the master synchronizing ring, the master synchronizing ring rotates under force, which drives the arc-shaped slider fixed to the master synchronizing ring to rotate synchronously. The arc-shaped spring is stressed and gradually lengthens, which on the one hand can buffer the resistance generated during the meshing process of the slave synchronizing ring and the master synchronizing ring, and on the other hand can avoid the situation where the master synchronizing ring and the slave synchronizing ring cannot mesh normally when there is misalignment between the transmission teeth of the master synchronizing ring and the transmission teeth of the slave synchronizing ring.

[0023] Furthermore, multiple fixing frames are fixed on the inner wall of the movable shell, and each fixing frame is rotatably mounted with a pulley. The surface of the pulley is provided with a limiting groove for the first rack to pass through and roll.

[0024] By adopting the above technical solution, when the movable shell moves, it drives the fixed frame to move, which in turn drives the pulley that is rotatably connected to the fixed frame to move. Since the surface of the pulley is provided with a limiting groove for the first rack to pass through and roll, it plays a good limiting role.

[0025] In summary, the present invention has the following beneficial effects: In this application, by improving the prior art, it is possible to realize the operating power of the air compressor under various belt tension states, thereby realizing dynamic testing of the air compressor and improving the accuracy of device detection.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Example 1: As Figure 1-2As shown in the figure, this application discloses an air compressor shaft power testing device, including a housing 1 and a fixing mechanism 7. A detection motor 2 is fixed inside the housing 1. The detection motor 2 is capable of intelligent control, and a main pulley 3 is fixedly sleeved on the output end of the detection motor 2. An adjustable mounting bracket 4 is provided on the top of the housing 1, and an air compressor 5 is detachably connected to the top of the mounting bracket 4. A driven pulley 6 is detachably connected to the drive shaft of the air compressor 5, and the output end of the air compressor 5 drive motor rotates through a belt connecting the main pulley 3 and the driven pulley 6. A through hole 8 is provided on the mounting bracket 4, and multiple threaded grooves 9 are provided on the top of the housing 1. First, the torque detection device (the core component of the detection mechanism 15 in Embodiment 2) is connected to the driven pulley 6. Then, the detection motor 2 drives the main pulley 3 to rotate. Under the transmission of the belt and the driven pulley 6, the drive shaft of the air compressor 5 is driven to rotate. At the same time, the torque detection device measures the torque generated when the driven pulley 6 rotates and can determine the operating power of the air compressor 5 according to the power calculation formula, so as to determine the energy consumption level, energy saving effect and operating efficiency of the air compressor 5. In addition, by moving the mounting bracket 4 on the housing 1, the position of the air compressor 5 on the housing 1 is changed, thereby changing the distance between the driven pulley 6 and the main pulley 3. This allows the operating power of the air compressor 5 to be measured under various belt tension states, thereby realizing dynamic testing of the air compressor 5 and improving the accuracy of the device detection.

[0038] A fixing mechanism 7 is mounted on the housing 1. The fixing mechanism 7 includes a bolt 71 and a limiting block 72. The bolt 71 passes through the through hole 8 and is threadedly connected to the corresponding threaded groove 9. The limiting block 72 is fixed to the upper end of the bolt 71 and is coaxially arranged with the bolt 71. The bottom of the limiting block 72 abuts against the surface of the mounting bracket 4, and the top of the limiting block 72 has an auxiliary groove with a regular hexagonal structure for a hexagonal wrench to pass through. Rotating the limiting block 72 causes the bolt 71 to rotate until the bolt 71 separates from the corresponding threaded groove 9. Then, the mounting bracket 4 is moved laterally until the through hole 8 moves above another threaded groove 9, and the bolt 71 is threadedly connected to the corresponding threaded groove 9 at this time, thus realizing the fastening operation of the mounting bracket 4.

[0039] Example 2: Figure 3-9As shown, this application discloses an air compressor shaft power testing device. Compared with Embodiment 1, the fixing mechanism 7 is replaced, and a displacement component 10, a lifting mechanism 11, and a detection mechanism 15 are added. The mounting frame 4 has a hollow structure with openings at both the top and bottom. The displacement component 10 is disposed on the housing 1 and includes a movable shell 101, a first rack 102, a displacement motor 103, a drive rod 104, and a displacement gear 105. The movable shell 101 is fixed to the bottom of the mounting frame 4, and a limiting hole 14 is provided through the side wall of the movable shell 101. The first rack 102 is fixed to the top of the housing 1 and slides in cooperation with the limiting hole 14. The displacement motor 103 is fixed inside the movable shell 101. The drive rod 104 is fixedly sleeved on the output end of the displacement motor 103, and the displacement gear 105 is fixedly sleeved on the drive rod 104 and meshes with the first rack 102. When the displacement motor 103 operates, it drives the drive rod 104 fixed to the output end of the displacement motor 103 and the displacement gear 105 fixed to the drive rod 104 to rotate. Since the displacement gear 105 meshes with the first rack 102, the displacement gear 105, the drive rod 104 fixed to the displacement gear 105, the displacement motor 103 fixed to the drive rod 104, the movable housing 101 fixed to the displacement motor 103, the mounting bracket 4 fixed to the movable housing 101, the air compressor 5 connected to the mounting bracket 4, the driven pulley 6 connected to the air compressor 5, and the driven synchronizing ring 1524 fixed to the driven pulley 6 can all move. This allows for the normal separation or engagement of the driven synchronizing ring 1524, and also enables the loosening or clamping of the air compressor 5 base, facilitating the use of the device.

[0040] The lifting mechanism 11 is mounted on the mounting frame 4. The lifting mechanism 11 includes a limiting component 111, a lifting component 112, a clamping component 113, and a rotating component 114. The limiting component 111 includes a lifting housing 1111, an annular plate 1112, a sliding plate 1113, and an annular frame 1114. The lifting housing 1111 is slidably disposed within the mounting frame 4, and the annular plate 1112 is fixed to the top of the lifting housing 1111. The base of the air compressor 5 passes through the annular plate 1112 and slides within it. Sliding holes 12 are provided through the side walls of the mounting frame 4, slidingly engaging with the sliding plates 1113. The number of sliding holes 12, the number of sliding plates 1113, and the number of annular frames 1114 are equal and their positions correspond one-to-one. The sliding plates 1113 extend into the annular frame 1114 and slidely engage with it. The sliding plates 1113 are fixed to the side walls on both sides of the lifting housing 1111, and the annular frame 1114 is fixed to the side walls of the mounting frame 4. The lifting assembly 112 drives the lifting housing 1111 to rise and fall, which in turn drives the annular plate 1112 fixed to the lifting housing 1111 and the air compressor 5 slidably connected to the annular plate 1112 to rise and fall, thereby changing the distance between the pulley 6 and the main pulley 3, thus changing the belt tension. In addition, adjusting the distance between the pulley 6 and the main pulley 3 to be less than the vertical length of the belt facilitates the connection or separation of the belt from the pulley 6 and the main pulley 3, making the device easier to use.

[0041] The lifting assembly 112 is used to drive the lifting housing 1111 to rise and fall. The lifting assembly 112 includes threaded posts 1121, a drive housing 1122, a worm gear 1123, a worm 1124, and a lifting motor 1125. Two threaded posts 1121 are provided, passing through the bottom of the annular frame 1114 and rotatably connected to it. The threaded posts 1121 also pass through the top of the sliding plate 1113 and are threadedly connected to it. The number of threaded posts 1121 is equal to the number of worm gears 1123, and their positions correspond one-to-one. The number of lifting assemblies 112 is equal to the number of sliding plates 1113, and their positions correspond one-to-one. The drive housing 1122 is fixed to the bottom of the annular frame 1114, and the worm gear 1123 is fixedly sleeved on the lower end of the threaded posts 1121 and located inside the drive housing 1122. The worm gear 1124 is rotatably mounted inside the drive housing 1122 and meshes with the worm wheel 1123. The lifting motor 1125 is fixed to the drive housing 1122 and drives the worm gear 1124 to rotate. When the lifting motor 1125 is working, it drives the worm gear 1124 to rotate, which in turn drives the worm wheel 1123 meshing with the worm gear 1124 and the threaded column 1121 fixedly connected to the worm wheel 1123 to rotate synchronously. This causes the sliding plate 1113 threadedly connected to the threaded column 1121 and the lifting housing 1111 fixed to the sliding plate 1113 to rise and fall, thereby changing the height of the air compressor 5.

[0042] The clamping assembly 113 is used to clamp the base of the air compressor 5. The clamping assembly 113 includes a movable plate 1131, a crossbar 1132, a double-acting screw 1133, and a clamping plate 1134. Two movable plates 1131 are provided, both slidably disposed within the lifting housing 1111. The crossbar 1132 is fixed within the lifting housing 1111 and slidably engages with both movable plates 1131. The double-acting screw 1133 passes through the side wall of the lifting housing 1111 and is rotatably connected to the lifting housing 1111. The double-acting screw 1133 has two sections of threads with opposite directions and equal pitch. The two movable plates 1131 are respectively disposed on the two sections of threads and threadedly connected. The clamping plate 1134 is fixed to the top of the movable plate 1131 and has an L-shaped structure. The top of the lifting housing 1111 has a through-hole 13 for the clamping plate 1134 to pass through and slide. The horizontal section of the clamping plate 1134 passes through the side wall of the annular plate 1112 and slides. The side wall of the horizontal section of the clamping plate 1134 near the air compressor 5 abuts against the base side wall of the air compressor 5. The number of clamping plates 1134, the number of mounting holes 13, and the number of movable plates 1131 are all equal and their positions correspond one-to-one. The rotating assembly 114 drives the bidirectional screw 1133 to rotate. Due to the good limiting effect of the crossbar 1132, the bidirectional screw 1133 is provided with two sections of threads with opposite directions and equal pitch. The two moving plates 1131 are respectively set on the two sections of threads and threadedly connected. This allows the two moving plates 1131 and the two clamping plates 1134 fixed to the two moving plates 1131 to move away from or towards each other, thereby separating or clamping the clamping plates 1134 from the surface of the air compressor 5 base, thus realizing the operation of loosening or clamping the air compressor 5. The setting of the clamping assembly 113 improves the stability of the air compressor 5 during testing.

[0043] The rotating assembly 114 drives the bidirectional screw 1133 to rotate. The rotating assembly 114 includes a baffle 1141, a limiting plate 1142, a rotating rack 1143, a connecting rod 1144, and a rotating gear 1145. The baffle 1141 is fixed to the side walls on both sides of the housing 1, and the limiting plate 1142 is fixed to the sliding plate 1113. The rotating rack 1143 is slidably disposed on the baffle 1141, and the connecting rod 1144 is fixed to the bidirectional screw 1133 and coaxially disposed with it. The limiting plate 1142 is slidably engaged with the rotating rack 1143. The rotating rack 1143 is slidably connected to the baffle 1141 through a guide rod, a vertical hole, and a connecting block, so that the rotating rack 1143 can only slide up and down along the surface of the baffle 1141. The rotating gear 1145 is fixedly sleeved on the connecting rod 1144 and meshes with the rotating rack 1143. When the sliding plate 1113 is raised or lowered, it drives the lifting shell 1111 connected to the sliding plate 1113, the bidirectional screw 1133 connected to the lifting shell 1111, the connecting rod 1144 connected to the bidirectional screw 1133, the rotating gear 1145 fixed to the connecting rod 1144, the limiting plate 1142 fixed to the sliding plate 1113, and the rotating rack 1143 slidably connected to the limiting plate 1142 to all rise or fall. Furthermore, the operation displacement component 10 drives the mounting frame 4 to move, which causes the lifting housing 1111 connected to the mounting frame 4, the bidirectional screw 1133 connected to the lifting housing 1111, the connecting rod 1144 connected to the bidirectional screw 1133, and the rotating gear 1145 fixed to the connecting rod 1144 to rotate. Since the rotating gear 1145 meshes with the rotating rack 1143, it can drive the rotating gear 1145, the connecting rod 1144 fixed to the rotating gear 1145, and the bidirectional screw 1133 fixed to the connecting rod 1144 to rotate, thereby realizing the operation of clamping or loosening the air compressor 5.

[0044] The detection mechanism 15 is mounted on the housing 1 and is used to detect the air compressor 5. The detection mechanism 15 includes a detection component 151, a transmission component 152, and a buffer component 153. The detection component 151 includes a mounting plate 1511, a horizontal plate 1512, a torque sensor 1513, and a hydraulic push rod 1514. The mounting plate 1511 is fixed to the housing 1, and the horizontal plate 1512 is slidably mounted on the mounting plate 1511. The torque sensor 1513 is fixed to the top of the horizontal plate 1512, and the hydraulic push rod 1514 is fixed to the mounting plate 1511, with its push rod end fixedly connected to the horizontal plate 1512. The transmission component 152 includes a transmission rod 1521, a connecting disc 1522, a main synchronizing ring 1523, and a driven synchronizing ring 1524. The transmission rod 1521 is fixed to the rotation detection end of the torque sensor 1513. A connecting disc 1522 is fixedly sleeved on a transmission rod 1521, and a main synchronizing ring 1523 is located on the side of the connecting disc 1522 away from the transmission rod 1521. The main synchronizing ring 1523 is rotatably mounted on the connecting disc 1522 and coaxially arranged with the connecting disc 1522. An arc-shaped hole 16 is provided through the side wall of the connecting disc 1522. A secondary synchronizing ring 1524 is fixedly sleeved on the secondary pulley 6 and meshes with the main synchronizing ring 1523. When the secondary pulley 6 rotates, it drives the secondary synchronizing ring 1524 fixed to the secondary pulley 6, the main synchronizing ring 1523 meshing with the secondary synchronizing ring 1524, the connecting disc 1522 connected to the main synchronizing ring 1523, the transmission rod 1521 fixed to the connecting disc 1522, and the rotation detection end of the torque sensor 1513 to rotate. The torque sensor 1513 can then detect the drive shaft connected to the secondary pulley 6. In addition, when the hydraulic push rod 1514 is working, its push rod end extends and retracts, which can drive the horizontal plate 1512 fixed to the hydraulic push rod 1514 and the torque sensor 1513 fixed to the horizontal plate 1512 to rise and fall, so as to cooperate with the lifting operation of the air compressor 5, thereby ensuring the normal detection work of the device.

[0045] The buffer assembly 153 includes an arc-shaped slider 1531, an arc-shaped rod 1532, and an arc-shaped spring 1533. The arc-shaped slider 1531 is fixed to the main synchronizing ring 1523 and slides in engagement with the arc-shaped hole 16. The arc-shaped rod 1532 is fixed inside the arc-shaped hole 16 and slides in engagement with the arc-shaped slider 1531. The arc-shaped spring 1533 is fixed to the inner wall of the arc-shaped slider 1531 and the arc-shaped hole 16. When the slave synchronizing ring 1524 moves closer to the master synchronizing ring 1523, and the transmission teeth of the slave synchronizing ring 1524 come into contact with the transmission teeth of the master synchronizing ring 1523, the master synchronizing ring 1523 rotates under force, which drives the arc-shaped slider 1531 fixed to the master synchronizing ring 1523 to rotate synchronously. The arc-shaped spring 1533 is subjected to force and gradually stretches, which on the one hand can buffer the resistance generated during the meshing of the slave synchronizing ring 1524 and the master synchronizing ring 1523, and on the other hand can avoid the situation where the master synchronizing ring 1523 and the slave synchronizing ring 1524 cannot mesh normally when there is misalignment between the transmission teeth of the master synchronizing ring 1523 and the transmission teeth of the slave synchronizing ring 1524.

[0046] Multiple mounting brackets 17 are fixed to the inner wall of the movable housing 101. Each mounting bracket 17 is rotatably mounted with a pulley 18. The surface of the pulley 18 has a limiting groove for the first rack 102 to pass through and roll into. When the movable housing 101 moves, it drives the mounting brackets 17 to move, which in turn drives the pulleys 18 rotatably connected to the mounting brackets 17 to move. Since the surface of the pulley 18 has a limiting groove for the first rack 102 to pass through and roll into, it plays a good limiting role.
