When the fixing assembly moves to fix the compressor, one side of the second fixed block contacts the compressor and can move a certain distance through the elasticity of the first spring.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, in the embodiment of the present invention, the compressor pressure detection device includes a base 1, a bearing platform 16 is installed on the top of the base 1, and fixing components are arranged on both sides of the bearing platform 16. A frame 5 is arranged above the bearing platform 16, a hydraulic rod 4 is installed on the top of the frame 5, and a detection frame 3 is installed on the outer wall of the hydraulic rod 4. Support seats 2 are installed at both ends of the bottom of the detection frame 3, and the two support seats 2 are rotatably connected to the detection frame 3 through a rotating component, and the two support seats 2 are connected to the base 1 through a lifting component;

[0032] The fixing assembly includes a fixing plate 8 arranged at the top of the base 1, and two fixing plates 8 are symmetrically arranged. One side of the two fixing plates 8 is installed with an electric telescopic rod 7, and the electric telescopic rod 7 is fixedly installed at the top of the base 1;

[0033] The rotating assembly includes a second rotating shaft 29 fixedly mounted on the inner wall of the detection frame 3, and one end of the second rotating shaft 29 away from the detection frame 3 is embedded in the interior of the support seat 2. A worm gear 30 is fixedly mounted on the outer wall of the second rotating shaft 29, and the bottom end of the worm gear 30 is meshedly connected with a worm 9, and a motor 10 is mounted on one end of the worm 9.

[0034] Existing: CN217276634U discloses a compressor pressure detection device. This patent discloses the framework 5 proposed in this application document and the specific pressure detection method. This technical means will not be described in detail here;

[0035] By the coordination of the fixed assembly and the rotating assembly, when the compressor is to be pressure tested, the compressor is first placed on the top of the carrier 16, and the position of the compressor is adjusted so that the air outlet on the top of the compressor is perpendicular to the frame 5, and then the fixed plate 8 is driven inward by the electric telescopic rod 7, and the compressor is fixed by the two fixed plates 8, and then the frame 5 is driven downward by the hydraulic rod 4 to dock the frame 5 with the air outlet of the compressor, and the two are installed, and finally the pressure test is performed;

[0036] After the air outlet at the top of the compressor is detected, the motor 10 is started by PLC control, the start of the motor 10 drives the rotation of the worm 9, the rotation of the worm 9 drives the rotation of the worm wheel 30, the rotation of the worm wheel 30 drives the rotation of the second rotating shaft 29, the rotation of the second rotating shaft 29 drives the rotation of the detection frame 3, the rotation of the detection frame 3 drives the rotation of the hydraulic rod 4 and the frame 5, so that the frame 5 rotates to the side of the compressor, parallel to the side air outlet, so as to perform pressure detection on it;

[0037] The above detection method not only improves the detection efficiency of the compressor with multiple exhaust ports, but also improves the convenience of operation.

[0038] The device has a self-locking function through the transmission mode of the worm 9 and the worm wheel 30, thereby improving the reliability and stability of the transmission.

[0039] like Figure 2As shown, the lifting assembly includes connecting columns 6 fixedly mounted at both ends of the bottom of the support seat 2, and the connecting columns 6 are arranged at both ends of the bottom of the support seat 2. The two connecting columns 6 are embedded in the interior of the base 1, and the internal thread of one of the connecting columns 6 is connected to a threaded rod 11, and the bottom end of the threaded rod 11 is fixedly mounted with a first bevel gear 12, and the bottom end of the first bevel gear 12 is meshingly connected with a second bevel gear 13, and the second bevel gear 13 is fixedly mounted on the outer wall of the first rotating shaft 14, and the first rotating shaft 14 is rotatably mounted in the interior of the base 1, and one end of the first rotating shaft 14 is fixedly connected with a hand wheel 15, and the hand wheel 15 is arranged on one side of the base 1.

[0040] Through the setting of the lifting assembly, when the air pressure of the air outlet located on the side of the compressor is detected, the first rotating shaft 14 can be driven to rotate by turning the hand wheel 15, and the rotation of the first rotating shaft 14 drives the rotation of the second bevel gear 13, and the rotation of the second bevel gear 13 drives the rotation of the first bevel gear 12, and the rotation of the first bevel gear 12 drives the rotation of the threaded rod 11, and the rotation of the threaded rod 11 drives the movement of the connecting column 6, and the movement of the connecting column 6 drives the movement of the support seat 2, and the movement of the support seat 2 drives the movement of the detection frame 3, so as to adjust the height of the frame 5 and ensure that the frame 5 and the air outlet are in a parallel position, so as to facilitate the connection between the two and perform air pressure detection on the air outlet on the side of the compressor.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, a first fixing block 17 and a second fixing block 31 are provided on one side of the fixing plate 8 . The first fixing block 17 is fixedly connected to the fixing plate 8 , and the second fixing blocks 31 are provided on both sides of the first fixing block 17 .

[0042] The fitting surface between the entire fixing structure and the compressor is arc-shaped, which can increase the contact area between the fixing structure and the compressor, thereby improving the fixing effect and ensuring stability during the detection process.

[0043] like Figure 4 As shown, one side of the second fixed block 31 is fixedly connected to a connecting shaft 19, and one end of the connecting shaft 19 away from the second fixed block 31 is fixedly connected to a limiting plate 20. The limiting plate 20 is slidably installed inside the fixed plate 8, and a first spring 21 is arranged between the limiting plate 20 and the fixed plate 8.

[0044] The elastic potential energy of the first spring 21 ensures that the second fixed block 31 always has a tendency to move toward one side of the compressor. When the fixing assembly moves to fix the compressor, one side of the second fixed block 31 contacts the compressor and can move a certain distance through the elasticity of the first spring 21. It not only has certain flexibility and adjustability, but also can reduce the friction and wear between the compressor and the fixed structure, thereby reducing the maintenance cost and downtime of the equipment.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting belt 18 is connected between the second fixing block 31 and the first fixing block 17 and the fixing plate 8 .

[0046] The connecting belt 18 is elastically arranged;

[0047] The gap between the second fixing block 31 and the first fixing block 17 and the fixing plate 8 is protected by the connecting belt 18 .

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, the support platform 16 is slidably connected to the base 1 , and a grip groove 22 is provided on the inner wall of one end of the support platform 16 .

[0049] Before and after the compressor is inspected, the support platform 16 can be slid on the top of the base 1, part of the support platform 16 can be pulled out of the top of the base 1, and then the compressor can be placed on the top of the base 1. The compressor can be moved to the bottom of the frame 5 by pushing the support platform 16, which makes it easier to adjust the position of the support platform 16 and improves the convenience of operation.

[0050] like Figure 5 and Figure 6 As shown, a pressing plate 23 is provided inside the grip groove 22, and guide plates 24 are fixedly connected to both sides of the pressing plate 23. A limiting rod 25 is provided at one end of the two guide plates 24 away from the pressing plate 23, and one end of the limiting rod 25 is embedded in the interior of the base 1.

[0051] During testing, the limiting rod 25 is embedded in the base 1 so that the support platform 16 is fixedly connected to the base 1, thereby ensuring the stability of the compressor during testing.

[0052] like Figure 1 , Figure 2 and Figure 5 As shown, the limiting rod 25 is slidably connected to the base 1 .

[0053] like Figure 5 and Figure 6 As shown, the guide plate 24 is slidably installed inside the bearing platform 16 , and a tension spring 26 is provided between the guide plate 24 and the bearing platform 16 .

[0054] When the support platform 16 needs to be moved, the pressing plate 23 is pressed inward. The movement of the pressing plate 23 drives the movement of the guide plate 24. The movement of the guide plate 24 deforms the tension spring 26 to store elastic potential energy. When the pressing plate 23 is released, the elastic potential energy is released by the tension spring 26 to reset it.

[0055] like Figure 5 and Figure 6As shown, both sides of the limiting rod 25 are fixedly connected with sliders 27 , and the two sliders 27 are slidably installed inside the bearing platform 16 , and second springs 28 are arranged between the two sliders 27 and the bearing platform 16 .

[0056] When the guide plate 24 moves to separate from the limiting rod 25 , the second spring 28 releases the elastic potential energy to move the limiting rod 25 back to its original position, so that the limiting rod 25 slides out of the base 1 , thereby releasing the fixation of the supporting platform 16 .

[0057] Working principle and usage process:

[0058] When the compressor is to be pressure tested, the compressor is first placed on the top of the carrier 16, and the position of the compressor is adjusted so that the air outlet on the top of the compressor is perpendicular to the frame 5. Then, the fixing plate 8 is driven to move inward by the electric telescopic rod 7. The movement of the fixing plate 8 drives the movement of the first fixing block 17 and the second fixing block 31, so that the sides of the first fixing block 17 and the second fixing block 31 are in contact with the outer wall of the compressor to fix them. Then, the frame 5 is driven downward by the hydraulic rod 4 to dock the frame 5 with the air outlet of the compressor, and the two are installed for pressure testing.

[0059] After the air outlet at the top of the compressor is detected, the motor 10 is started by PLC control, the start of the motor 10 drives the rotation of the worm 9, the rotation of the worm 9 drives the rotation of the worm wheel 30, the rotation of the worm wheel 30 drives the rotation of the second rotating shaft 29, the rotation of the second rotating shaft 29 drives the rotation of the detection frame 3, the rotation of the detection frame 3 drives the rotation of the hydraulic rod 4 and the frame 5, so that the frame 5 rotates to the side of the compressor;

[0060] Then, the first rotating shaft 14 is driven to rotate by rotating the hand wheel 15, and the rotation of the first rotating shaft 14 drives the rotation of the second bevel gear 13, and the rotation of the second bevel gear 13 drives the rotation of the first bevel gear 12, and the rotation of the first bevel gear 12 drives the rotation of the threaded rod 11, and the rotation of the threaded rod 11 drives the movement of the connecting column 6, and the movement of the connecting column 6 drives the movement of the support seat 2, and the movement of the support seat 2 drives the movement of the detection frame 3, so as to adjust the height of the frame 5, ensure that the frame 5 is in a parallel position with the air outlet, and perform pressure detection on it;

[0061] Remove the compressor after pressure testing the air outlets on the top and sides.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
