[0029] The following describes the specific structure of an inspection device for a position controller:

[0030] Please refer to Figures 1 to 5 , for the inspection device for a position controller in this embodiment, the inspection device includes a rotating assembly 1, and the rotating assembly 1 is configured to rotate the position controller. The rotating assembly 1 includes a motor 101. The inspection device further includes a frame body 5, and the frame body 5 is made of a high-strength material to ensure a certain bearing capacity. The motor 101 is fixedly connected to the frame body 5. The rotating assembly 1 further includes a first gear 102 and a second gear 103. The first gear 102 is connected to the motor 101, and the first gear 102 also meshes with the second gear 103. The first gear 102 is driven by the motor 101 to rotate, and then the second gear 103 rotates passively. The rotating assembly 1 further includes a clamping member 104, and the second gear 103 is engaged with the clamping member 104. Preferably, in this embodiment, the second gear 103 and the clamping member 104 are fixedly connected by bolts. Under the rotation of the second gear 103, the clamping member 104 also rotates synchronously, and then the position controller disposed at one end within the clamping member 104 also rotates accordingly.

[0031] Furthermore, the inspection device further includes a jacking assembly 2 and a positioning assembly 3. The jacking assembly 2 and the positioning assembly 3 cooperate with each other. The jacking assembly 2 applies a force to the position controller and the positioning assembly 3 restricts part of the displacement of the position controller, so as to accurately inspect by simulating the force in the working state of the position controller. The jacking assembly 2 includes a jacking member 201 and a bearing member 202. The jacking member 201 includes a housing 2011 and a moving member 2012. The frame body 5 includes a first carrier 501. The housing 2011 and the bearing member 202 are both fixedly connected to the first carrier 501. The moving member 2012 is movably engaged with the bearing member 202 relative to the housing 2011 along a first direction. In this embodiment, the first direction is Figure 3 The vertical direction shown is the direction perpendicular to the horizontal ground in the working state.

[0032] Further, the carrier 202 is connected to the clamping member 104, and a buffer portion 6 and a bearing portion 7 are further provided between the carrier 202 and the clamping member 104. A force is applied to the carrier 202 through the movement of the moving member 2012. Then, the carrier 202 transmits the force to the clamping member 104 through the buffer portion 6 and then to the position controller. A protrusion 1041 is provided on the surface of the clamping member 104, and the bearing portion 7 is clamped to the protrusion 1041, ensuring the stable rotation of the clamping member 104 relative to the carrier 202.

[0033] Further, the positioning assembly 3 includes a first positioning portion 301 and a second positioning portion 302. The frame 5 includes a second carrier 502 and a third carrier 503. The first positioning portion 301 is provided on the second carrier 502, and the second positioning portion 302 is provided on the third carrier 503. The first positioning portion 301 includes a first cylinder 3011 and a first positioning member 3012. The first cylinder 3011 is connected to the first positioning member 3012, and both are uniformly arranged on the second carrier 502. In this embodiment, four of the first cylinders 3011 and the first positioning members 3012 are respectively arranged in a circumferential and uniform manner. The first positioning member 3012 is further provided with a first hole 30121. Preferably, in this embodiment, the first positioning member 3012 is fixed to the second carrier 502 by bolts. When the bolts are loosened, the first cylinder 3011 can push the first positioning member 3012 to move in the first hole 30121, thereby realizing the positioning of the first positioning member 3012 to the position controller and preventing the position controller body from moving in the first direction due to the force of the lifting assembly 2.

[0034] Further, the second positioning portion 302 includes a second cylinder 3021 and a second positioning member 3022. The second cylinder 3021 is connected to the second positioning member 3022, and both are uniformly arranged on the third carrier 503. In this embodiment, two of the second cylinders 3021 and two of the second positioning members 3022 are respectively arranged. The second positioning member 3022 includes a first portion 30221 and a second portion 30222. The first portion 30221 and the second portion 30222 cooperate with each other. In this embodiment, the two second positioning members 3022 are arranged in the first direction in opposite directions to realize the cooperation between the first portion 30221 and the second portion 30222. In this way, the second positioning portion 302 can clamp the regulator in the position controller.

[0035] Further, the inspection device further includes a lifting component 4, which is used to move the regulator in the position controller along the first direction. The lifting component 4 includes a third cylinder 401. The frame 5 further includes a fourth carrier 504. The third cylinders 401 are uniformly arranged on the fourth carrier 504. The lifting component 4 further includes a connecting rod 402, which is telescopically arranged on the third cylinder 401. One end of the connecting rod 402 is also connected to the third carrier 503. In this embodiment, two third cylinders 401 and corresponding connecting rods 402 are provided. Through the movement of the third cylinder 401, the regulator moves relative to the position controller housing along the first direction.

[0036] The following describes the specific working process of the inspection device for a position controller according to an embodiment of the present invention as follows:

[0037] First, the rotation component 1 is used to synchronously rotate the position controller connected to the clamping member 104. Then, the jacking component 2 is used to simulate a force along the first direction on the position controller as needed. At the same time, the positioning component 3 is used to position the position controller housing on the one hand, ensuring that the position controller housing does not move along the first direction while being stressed, and on the other hand, locking and positioning the regulator in the position controller. Finally, the lifting component 4 is used to move the regulator relative to the position controller housing in the first direction for subsequent inspection. Through the combined action of the rotation component 1, the jacking component 2, the positioning component 3, and the lifting component 4, an integrated inspection function is achieved to ensure that the screw pump operates stably and efficiently, while reducing the equipment failure rate and maintenance cost.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
