[0030] like Figures 1-9The utility model discloses a multi-stage pump maintenance turning platform, comprising a base 1, a storage plate 2 is rotatably mounted on the base 1, a placement rack 6 is rotatably mounted on the storage plate 2, a turning unit for driving the storage plate 2 and the placement rack 6 to rotate is fixedly mounted on the base 1, a clamping unit is slidably mounted on the placement rack 6, and a locking unit for limiting the clamping unit is fixedly mounted on the placement rack 6. According to the size of the pump body that needs to be repaired, the position of the clamping unit on the placement rack 6 is adjusted, and the clamping unit is fixed by the locking unit, so that the clamping unit can better clamp and fix the pump body that needs to be repaired, and the pump body that needs to be repaired is placed on the placement rack 6 and clamped and fixed by the clamping unit. The storage plate 2 and the placement rack 6 are driven to rotate by the turning unit, so that the pump body that needs to be repaired can be turned over, which is convenient for repairing the pump body at different angles.

[0031] like Figures 1-8As shown, the clamping unit includes a mounting frame 301, the mounting frame 301 is slidably arranged on the placement frame 6, the mounting frame 301 is connected to the locking unit, a hydraulic telescopic mechanism 302 set relatively tilted is fixedly installed on the mounting frame 301, a buffer box 303 is fixedly installed on the telescopic end of the hydraulic telescopic mechanism 302, a movable rod 305 is slidably installed on the buffer box 303, and a limiting plate 311 and a mounting plate 307 are respectively installed at both ends of the movable rod 305, a spring 306 is sleeved on the part of the movable rod 305 located between the buffer box 303 and the mounting plate 307, the limiting plate 311 is slidably connected to the buffer box 303, and the mounting plate 307 is connected to the clamping plate 308 by bolts. The holding plate 308 is fixedly installed with anti-slip teeth 309 in an eight-shaped shape. According to the position where the pump body needs to be supported during maintenance and disassembly, the sliding mounting frame 301 is adjusted, the position of the mounting frame 301 on the placement frame 6 is adjusted, and the mounting frame 301 is locked and fixed by the locking unit, so that the mounting frame 301 can better support and store different pump bodies. According to the shape of the pump body, a suitable clamping plate 308 is selected to be installed on the mounting plate 307, and the clamping plate 308 and the mounting plate 307 are locked and fixed by bolts. The suitable clamping plate 308 is selected for use according to the shape of the pump body, which can increase the contact area between the clamping plate 308 and the pump body, so that the clamping plate 308 fits better on the pump body. The outer surface of the pump body is clamped and fixed to improve the stability of the pump body when clamped, and the limit plate 311 is used to prevent the movable rod 305 from being separated from the buffer box 303. The pump body that needs to be repaired is placed on the mounting frame 301, and the buffer box 303 is driven to move by the telescopic end of the hydraulic telescopic mechanism 302. The buffer box 303 drives the mounting plate 307 and the clamping plate 308 to move through the movable rod 305. The clamping plate 308 is supported on the outer surface of the pump body by the anti-slip teeth 309. As the telescopic end of the hydraulic telescopic mechanism 302 moves, the clamping plate 308 and the anti-slip teeth 309 push the movable rod 305 in the opposite direction through the mounting plate 307, and compress the spring 306, so that the clamping plate 308 and the When the pump body is in flexible contact and the clamping plate 308 and the mounting plate 307 are unable to push the movable rod 305 in the opposite direction, the hydraulic telescopic mechanism 302 drives the clamping plate 308 and the anti-slip teeth 309 to press against the surface of the pump body through the buffer box 303, the movable rod 305 and the mounting plate 307. The relatively arranged hydraulic telescopic mechanism 302 applies a multi-point clamping force to the pump body in the circumferential direction, effectively improving the firmness and stability of the pump body during clamping. At the same time, since the anti-slip teeth 309 on the clamping plate 308 are arranged in an eight-shaped shape, the anti-slip teeth 309 apply a force in the opposite direction to the pump body, and during the process of turning the pump body over for maintenance, the pump body is effectively prevented from sliding and falling, thereby improving safety.

[0032] like Figure 5As shown, a pressure sensor 304 is fixedly installed in the buffer box 303. The pressure sensor 304 corresponds to the limit plate 311. When the placed pump body is clamped and fixed, the clamping plate 308 drives the limit plate 311 through the mounting plate 307 and the movable rod 305 to apply a force to the pressure sensor 304. The force of the clamping plate 308 clamping the pump body is detected by the pressure sensor 304, so as to facilitate the control of the force clamping the pump body.

[0033] like Figure 2 As shown, the movable rod 305 is square, and the square design is used to limit the movable rod 305 to prevent the movable rod 305 from rotating, thereby improving the stability of the movable rod 305.

[0034] like Figure 2 、 Figure 4 、 Figure 5 As shown, a slip sensor 310 is fixedly installed on the buffer box 303. During the inspection and flipping of the pump body that needs to be inspected, the slip state of the pump body is monitored by the slip sensor 310 to ensure that when the pump body slides, it can be discovered in time, the clamping force of the pump body can be adjusted, the safety is improved, and the pump body is prevented from slipping and causing danger.

[0035] like Figure 1 、 Figure 4 、 Figure 8 、 Figure 9 As shown, the flip unit includes a rotating motor 401, a tooth plate 404, a second gear 403 and a dual-axis motor 406. The rotating motor 401 and the tooth plate 404 are fixedly mounted on the lower surface of the storage plate 2. The first gear 402 is fixedly mounted on the output shaft of the rotating motor 401. The second gear 403 is fixedly mounted on the lower surface of the placement rack 6. The second gear 403 is meshed with the first gear 402. The dual-axis motor 406 is fixedly mounted on the base 1. The output shaft of the dual-axis motor 406 is fixedly mounted with a third gear 405. The third gear 405 is meshed with the tooth plate 404. When the process needs to flip the pump body, the first gear 402 is driven to rotate by the rotating motor 401, and the first gear 402 drives the placement rack 6 to rotate through the second gear 403, so that the angle of the pump body on the placement rack 6 is adjusted. At the same time, the third gear 405 is driven to rotate by the dual-axis motor 406, and the third gear 405 drives the storage plate 2 to rotate through the gear plate 404, so that one end of the storage plate 2 rises, so that the pump body on the placement rack 6 is in a tilted state. By rotating and tilting the pump body on the placement rack 6, the pump body is flipped, which facilitates the maintenance of the pump body at different angles.

[0036] like Figure 3 、 Figure 4 、 Figure 8As shown, the locking unit includes a through hole 502 and a screw 501. The through holes 502 are arranged on both sides of the placement frame 6. A threaded hole is provided on the side of the mounting frame 301 corresponding to the through hole 502. The screw 501 is slidably installed in the through hole 502. The screw 501 is threadedly connected to the threaded hole of the mounting frame 301. After the position of the mounting frame 301 on the placement frame 6 is adjusted, the screw 501 is installed in the through hole 502 corresponding to the mounting frame 301, and the end of the screw 501 enters the mounting frame 301, thereby locking and fixing the mounting frame 301.

[0037] like Figure 1 、 Figure 7 、 Figure 8 As shown, columns 7 are fixedly installed at the four corners of the upper surface of the base 1, and safety gratings 8 are fixedly installed on the opposite sides of the columns 7. The safety gratings 8 are supported by the columns 7. During the detection of flipping, safety detection is performed through the safety gratings 8. When the staff enters the flipping area, the flipping action can be stopped immediately, thereby improving safety during the work process.

[0038] Working principle: Figures 1-8 As shown, according to the position where the pump body needs to be clamped and supported, slide the mounting bracket 301, adjust the position of the mounting bracket 301 on the placement rack 6, install the screw 501 in the through hole 502 corresponding to the mounting bracket 301, and make the end of the screw 501 enter the mounting bracket 301, so as to lock and fix the mounting bracket 301, select a suitable clamping plate 308 according to the shape of the pump body and install it on the mounting plate 307, and lock and fix the clamping plate 308 and the mounting plate 307 with bolts;

[0039] like Figures 1-8 As shown, the pump body that needs to be repaired is placed on the mounting frame 301, and the buffer box 303 is driven to move by the telescopic end of the hydraulic telescopic mechanism 302. The buffer box 303 drives the mounting plate 307 and the clamping plate 308 to move through the movable rod 305. The clamping plate 308 is pressed against the outer surface of the pump body through the anti-slip teeth 309. As the telescopic end of the hydraulic telescopic mechanism 302 moves, the clamping plate 308 and the anti-slip teeth 309 push the movable rod 305 in the opposite direction through the mounting plate 307. When the spring 306 is compressed and the clamping plate 308 and the mounting plate 307 are unable to push the movable rod 305 in the opposite direction, the hydraulic telescopic mechanism 302 drives the clamping plate 308 and the anti-slip teeth 309 to press against the surface of the pump body through the buffer box 303, the movable rod 305 and the mounting plate 307. At this time, the movable rod 305 applies a force to the pressure sensor 304 through the limit plate 311, and the pressure sensor 304 detects the force of the clamping plate 308 clamping the pump body.

[0040] When the pump body needs to be turned over during maintenance, Figure 1 、 Figure 4 、 Figure 8 、 Figure 9 As shown, the first gear 402 is driven to rotate by the rotary motor 401, and the first gear 402 drives the placement rack 6 to rotate through the second gear 403, thereby adjusting the angle of the pump body on the placement rack 6. At the same time, the third gear 405 is driven to rotate by the dual-axis motor 406, and the third gear 405 drives the storage plate 2 to rotate through the gear plate 404, so that one end of the storage plate 2 rises, thereby making the pump body on the placement rack 6 in an inclined state. By rotating and tilting the pump body on the placement rack 6, the pump body is flipped, which facilitates the maintenance of the pump body at different angles.

[0041] When flipping, Figures 1-8 As shown, the hydraulic telescopic mechanisms 302 arranged opposite to each other apply a clamping force at multiple points on the pump body in the circumferential direction, and the anti-slip teeth 309 arranged in an eight-shaped pattern apply a force in the opposite direction to the pump body, thereby improving the anti-slip property of the pump body and preventing the pump body from sliding during the flipping process;

[0042] During the pump body reversal process, if Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown, the sliding state of the pump body is monitored by the slip sensor 310 to ensure that the sliding of the pump body can be discovered in time. When the slip sensor 310 detects that the pump body is sliding, the signal feedback of the slip sensor 310 is used to control the hydraulic telescopic mechanism 302 to increase the clamping force on the pump body to prevent the pump body from sliding. At the same time, safety detection is performed through the safety grating 8, and the staff can immediately stop the flipping action when entering the flipping area, thereby improving safety during the work process.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
