[0026] When using the hydraulic operating mechanism valve body disassembly device of the above structure, first connect one end of each bolt rod to the first threaded hole 301 corresponding to the valve body 300, and the other end of each bolt rod passes through the corresponding first waist-shaped hole 201 and installs a limit nut. Then, the displacement sensor 400 detects the distance between it and the bolt rod, and people move the fixing frame 100 until the distances detected by the two displacement sensors 400 are equal to stop moving the fixing frame 100. Finally, the controller determines that the screw rod 110 coincides with the central axis of the valve body 300, and the controller drives the driving assembly 120 to operate, so that the screw rod 110 rotates to drive the mounting member 200 to move upward, so that the valve body 300 can be automatically extracted along the central axis direction of the valve body 300, which is beneficial to avoid the direction deviation of the valve body 300 when manually extracting the valve body 300, and is also beneficial to evenly distribute the force acting on the valve body 300 by the mounting member 200 to the valve body 300, thereby improving the stability and automation of the disassembly of the valve body 300, thereby improving the maintenance efficiency of subsequent equipment.

[0027] See also Figure 1 and Figure 2 Further, the fixing frame 100 includes two first mounting plates 101 spaced apart in the vertical direction, the screw rod 110 is rotatably arranged between the two first mounting plates 101, a slide rail 130 is arranged between the two first mounting plates 101, the slide rail 130 is arranged in parallel with the screw rod 110, the screw rod 110 is threadedly matched with a slider 140, the slider 140 is slidably matched with the slide rail 130, and the mounting member 200 is connected to the lower end of the slider 140. Specifically, the matching of the slider 140 and the slide rail 130 can limit the rotation of the mounting member 200, so that the mounting member 200 can drive the valve body 300 to reciprocate in the vertical direction, further avoiding the deviation of the extraction direction of the valve body 300. In some embodiments, the slide rail 130 can also be replaced by a guide rod, and the slider 140 is provided with a guide hole matched with the guide rod, which can also guide and limit the movement of the mounting member 200.

[0028] See also Figure 1 and Figure 2, further, the fixing frame 100 also includes two second mounting plates 102 arranged opposite to each other, the second mounting plates 102 are connected to one side of the two first mounting plates 101, the slide rail 130 includes a card plate 131 arranged parallel to the second mounting plate 102, and the slider 140 is provided with a card slot that is slidably matched with the card plate 131, so that the movement of the mounting member 200 is guided and limited by the match between the card plate 131 and the card slot. Specifically, the first mounting plate 101 and the second mounting plate 102 are integrally formed by integral injection molding, or are fixed to each other by welding, which is conducive to ensuring the structural strength of the fixing frame 100. Among them, the slider 140 includes an L-shaped plate, the transverse surface of the L-shaped plate is connected to the first mounting block, the transverse surface of the L-shaped plate and the first mounting block are both provided with mounting holes that are threadedly matched with the screw rod 110, the vertical surface of the L-shaped plate is connected to the second mounting block, and the card slot is provided on the side of the second mounting block, so that the slider 140 can match with the screw rod 110 and the slide rail 130. In addition, the slide rail 130 further includes a connecting plate 132 connected to the second mounting plate 102 . The connecting plate 132 is arranged along the vertical direction, so that the length direction of the slide rail 130 is arranged parallel to the axis of the screw rod 110 .

[0029] See also Figure 1 and Figure 2 , further, the lower end of the second mounting plate 102 is connected to a fixing plate 103, and the fixing plate 103 is provided with a second waist-shaped hole 104 along its length direction, and the axis of the second waist-shaped hole 104 is parallel to the axis of the first waist-shaped hole 201, and the second waist-shaped hole 104 is used to connect to the second threaded hole 501 of the hydraulic operating mechanism 500. Specifically, the fixing plate 103 is provided with a bolt rod, one end of the bolt rod is connected to the second threaded hole 501, and the other end of the bolt rod passes through the second waist-shaped hole 104 and is connected to a limit nut. When the distances detected by the two displacement sensors 400 are equal, people stop moving the fixing frame 100 and tighten the limit nut to the bolt rod, so as to better lock the installation position of the fixing frame 100, thereby preventing the fixing frame 100 from moving and affecting the extraction of the valve body 300. It can be understood that the present device utilizes the first threaded hole 301 and the second threaded hole 501 existing in the existing equipment, and uses the end surface of the valve body 300 as the base surface to fix the mounting member 200 and the fixing frame 100, thereby facilitating the subsequent extraction of the valve body 300 by moving the mounting member 200, thereby ensuring the convenience of disassembly of the valve body 300.

[0030] See also Figure 1 and Figure 2Further, the mounting member 200 includes two parallel vertical plates 202, the upper ends of the vertical plates 202 are connected to the slider 140, and two displacement sensors 400 are respectively arranged on the corresponding vertical plates 202. The axis of the screw rod 110 is arranged colinearly with the symmetry axis of the two vertical plates 202, so that the two displacement sensors 400 detect the distance between the screw rod 110 and the corresponding bolt rod, and then indirectly judge whether the central axis of the screw rod 110 and the valve body 300 coincide, which is conducive to the subsequent smooth extraction of the valve body 300 along the central axis of the valve body 300. It can be understood that the vertical plate 202 is fixed to the slider 140 by welding, and the displacement sensor 400 is fixed to the vertical plate 202 by bolt connection, which will not be described in detail here.

[0031] See also Figure 1 and Figure 2 , further, the lower end of the vertical plate 202 is connected to the horizontal plate 203, and the horizontal plate 203 is provided with a first waist-shaped hole 201 along its length direction, and the vertical plate 202 and the horizontal plate 203 are an integrated structure. Specifically, the horizontal plate 203 abuts against the end surface of the valve body 300, which is conducive to increasing the contact area of ​​the subsequent mounting member 200 to lift the valve body 300, thereby improving the stability of the extraction valve body 300. Among them, the vertical plate 202 and the horizontal plate 203 are formed into one body by an integral injection molding method, or fixed together by a welding method, which is conducive to ensuring the structural strength of the mounting member 200.

[0032] Furthermore, the displacement sensor 400 is a laser sensor, and the output end of the laser sensor faces the bolt rod, so that the laser sensor is used to improve the accuracy and precision of the detection distance. The displacement sensor 400 can also be replaced by an ultrasonic sensor, which will not be described in detail here.

[0033] Furthermore, the fixing frame 100 is provided with a display screen, the display screen is electrically connected with a data processing module, the displacement sensor 400 is electrically connected with the data processing module, and the display screen is used to display the values ​​detected by the two displacement sensors 400, so that people can stop the moving fixing frame 100 in time through the values. Among them, the controller is electrically connected with a switch button, and the switch button controls the operation or stop of the driving component 120. When the two values ​​displayed on the display screen are equal, people tighten the limit nut on the corresponding bolt rod so that the mounting member 200 and the valve body 300 are connected as one, and the fixing frame 100 is fixed to the hydraulic operating mechanism 500. Finally, the switch button is pressed so that the driving component 120 drives the screw rod 110 to rotate, which is conducive to reducing the shaking caused by the connection to ensure the stability of the extraction valve body 300, and also enables people to manually control the distance of movement of the mounting member 200, thereby improving people's use experience. It can be understood that if the displacement sensor 400 generates a data signal, the data processing module uses a single-chip microcomputer to read it, and the single-chip microcomputer controls the display screen for display. If the displacement sensor 400 generates an analog signal, the data processing module further includes an A / D conversion circuit to convert the analog signal into a digital signal and output it using a single chip microcomputer.

[0034] See also Figure 1 and Figure 2 , further, the driving assembly 120 includes a motor 121, the motor 121 is electrically connected to the controller, the motor 121 is arranged on the fixed frame 100, and the output end of the motor 121 is connected to the screw 110 through a belt mechanism 122.

In some embodiments, a gear reducer 123 is connected between the motor 121 and the belt mechanism 122, so as to increase the output torque of the motor 121 to increase the axial load of the screw 110.
