The surface of the compression spring 19 is sprayed with anti-rust paint.
[0022] As a technical optimization of this utility model, by setting up the mounting bracket 17, locking bracket 18, slot and compression spring 19, when the operator needs to replace the positioning rod 10, the operator can pull the locking bracket 18 upward until the locking bracket 18 separates from the slot, thereby releasing the lock on the movable block 9. Then the operator pulls the movable block 9 to the right and disassembles the positioning rod 10. The operator can replace the positioning rod 10 with a suitable diameter according to the inner diameter of the gate valve body to be processed.
[0023] refer to Figure 1 , Figure 3 and Figure 4 The second port 14 is rotatably connected to a first threaded rod 20, which is threadedly connected to the slider 15. The right side of the first threaded rod 20 extends to the right side of the slide rail 13 and is fixedly connected to a handle.
[0024] As a technical optimization of this utility model, by setting the first threaded rod 20 and the handle, the operator can rotate the handle to drive the first threaded rod 20 to rotate, thereby driving the slider 15 to move left or right.
[0025] refer to Figure 1 , Figure 3 and Figure 4 The slide rail 13 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the slide rail 13, while the inner ring of the bearing is fixedly connected to the first threaded rod 20. The bearing is internally provided with lubricating oil and a sealed shaft cover.
[0026] As a technical optimization of this utility model, by setting the bearing, the friction between the slide rail 13 and the first threaded rod 20 can be reduced, thereby facilitating the rotation of the first threaded rod 20.
[0027] refer to Figure 1 , Figure 3 and Figure 4 A support plate 21 is fixedly connected to the top of the support frame 12. A reinforcing rod 22 is fixedly connected to the front and rear sides of the right side of the support plate 21. The end of the reinforcing rod 22 away from the support plate 21 is fixedly connected to the slide rail 13.
[0028] As a technical optimization of this utility model, the stability of fixing the slide rail 13 can be improved by setting the support plate 21 and the reinforcing rod 22.
[0029] refer to Figure 1 A cylinder 23 is fixedly connected to all four sides of the bottom of the base plate 1. A second threaded rod 24 is threaded inside the cylinder 23. A support pad 25 is fixedly connected to the bottom of the second threaded rod 24.
[0030] As a technical optimization of this utility model, by setting up the cylinder 23, the second threaded rod 24 and the support pad 25, the operator can rotate the second threaded rod 24, thereby driving the support pad 25 to move up or down, thereby adjusting the height or level of the base plate 1.
[0031] The working principle and usage process of this utility model are as follows: During use, the operator holds the gate valve body and aligns one of the two openings on either side of the valve body with the positioning rod 10. Then, the operator starts the motor 7 to rotate, causing the disc frame 6, sleeve 8, movable block 9, and positioning rod 10 to rotate. The surface of the positioning rod 10 has threads that fit the inner walls of both sides of the gate valve body. When the positioning rod 10 rotates, it connects with the gate valve body via these threads, thus supporting the valve body. The operator can then adjust the positions of the slider 15 and the insertion rod 16 left and right, so that the insertion rod 16 is positioned at the valve body adjustment component mounting port at the top of the gate valve body. Above, the operator activates the second electric cylinder 11 to retract, thereby driving the support frame 12, slide rail 13, slider 15 and insert rod 16 to move downward. Part of the insert rod 16 is inserted into the mounting port at the top of the gate valve body. Under the limiting action of the insert rod 16, the gate valve body can be prevented from rotating during processing. When positioning the gate valve body, this device will not obstruct a large area of the gate valve body surface, thus facilitating the operator's processing of the gate valve body. The operator can activate the first electric cylinder 5 to extend, thereby driving the movable frame 4 to move upward, thereby indirectly driving the gate valve body to move upward, and thus adjusting the height of the gate valve body.
