Technical Field

[0001] This application relates to the technical field of valve production, and particularly to an integrated machine for assembling and disassembling the spring cylinder of a valve sector actuator. Background Art

[0002] The patent with the publication number CN118224375A and the name "Valve Structure with High-Performance Spring Rotary Energy Accumulator" discloses a valve structure with a high-performance spring rotary energy accumulator, including an output transmission shaft for connecting with a valve stem used in cooperation with the spring rotary energy accumulator. It also includes an upper spring cylinder body, a lower spring cylinder body, and a scroll spring. The upper spring cylinder body and the lower spring cylinder body are buckled with each other to form a sealed cavity. One end of the output transmission shaft penetrates through the upper spring cylinder body, and the other end penetrates through the lower spring cylinder body. The scroll spring is located in the cavity and sleeved on the output transmission shaft. One end of the scroll spring is inserted and connected with the output transmission shaft, and a limiting member for locking the end of the scroll spring is arranged between the other end and the lower spring cylinder body. A position-adjusting component for changing the initial winding posture of the scroll spring is arranged on the lower spring cylinder body. This application has the effect of reducing the failure rate of the spring rotary energy accumulator and improving the transmission efficiency of the spring rotary energy accumulator in the service environment where the valve stem rotates frequently.

[0003] When installing the valve structure, it is necessary to install the spring into the lower spring cylinder body, and then connect the lower spring cylinder body with the upper spring cylinder body and the cylinder. During the installation process of the upper spring cylinder and the lower spring cylinder, the spring needs to be in an energy storage state, and the force required for spring energy storage is relatively large and cannot be completed manually. Therefore, there is an urgent need for a device for installing the upper spring cylinder and the lower spring cylinder together. Summary of the Invention

[0004] In order to realize the installation and disassembly of the upper spring cylinder and the lower spring cylinder, this application provides an integrated machine for assembling and disassembling the spring cylinder of a valve sector actuator.

[0005] The above technical objectives of this application are achieved through the following technical solutions: An integrated machine for assembling and disassembling the spring cylinder of a valve sector actuator includes a frame. A fixing structure for fixing the lower spring cylinder body is installed below the frame. A rotating shaft is connected above the frame. The rotating shaft is rotationally connected with the rotating shaft of the vane piston assembly. The rotating shaft is connected with a driving motor capable of driving the rotating shaft to rotate. When the driving motor rotates, the rotating shaft drives the rotating shaft of the vane piston assembly to rotate.

[0006] The cam is then moved back to the left of the piston rod and the piston rod is moved back to the right of the piston rod, and the piston rod is moved back to the right of the piston rod, so that the piston rod can be moved back to the left of the piston rod.

[0007] Optionally, the driving motor is connected to a worm, the worm is rotatably connected to the frame, the worm is engaged with a worm wheel, and the worm wheel is connected to the rotating shaft.

[0008] By adopting the above solution, the torque required for the deformation of the volute spring is relatively large. The transmission of the worm and the worm wheel can reduce the output torque required for the drive motor, so that the drive motor can drive the rotating shaft to rotate more smoothly, and the worm wheel has a self-locking function to prevent the rotating shaft from rotating.

[0009] Optionally, a through hole is opened in the middle of the worm gear, the rotating shaft passes through the through hole, and the rotating shaft is slidingly connected to the worm gear, a reversing wheel is arranged above the frame, one end of the rotating shaft is fixedly connected to a steel rope, the steel rope passes around the reversing wheel, and the end of the steel rope facing away from the rotating shaft is connected to a counterweight block.

[0010] By adopting the above solution, the rotating shaft can slide up and down, which facilitates the installation of the rotating shaft and the rotating shaft of the leaf piston assembly. The rotating shaft can be adjusted to adapt to spring cylinders of more specifications, and the steel rope will not interfere with the rotation of the rotating shaft.

[0011] Optionally, the rotating shaft is connected to a connecting block, one end of the connecting block is provided with a rotating shaft groove for inserting the rotating shaft of the leaf piston assembly, and the end of the connecting block facing away from the rotating shaft of the leaf piston is provided with a connecting outer groove, one end of the rotating shaft is provided with a connecting inner groove, and one end of the connecting block with the connecting outer groove is inserted into the connecting inner groove of the rotating shaft, and the shape of the connecting inner groove is a polygonal groove.

[0012] By adopting the above solution, when assembling spring cylinders of different specifications, it is only necessary to replace the connecting blocks of different specifications without replacing the rotating shaft, making the all-in-one machine more convenient to use when assembling spring cylinders of different specifications.

[0013] Optionally, the fixing structure includes a base plate. A transmission cavity is formed inside the base plate. A transmission disk is rotatably connected inside the transmission cavity. A spiral tooth is formed on one side surface of the transmission disk. A plurality of chutes pointing to the center of the circle are formed on one side surface of the base plate. The chutes communicate with the transmission cavity, and a slider is slidably connected inside the chutes. A tooth meshing with the spiral tooth is arranged on one side of the slider close to the transmission disk. When the transmission disk rotates, the slider is driven to slide along the chute, and the slider is fixedly connected with a clamp block for clamping the lower spring cylinder.

[0014] By adopting the above scheme, when fixing the lower spring cylinder, place the lower spring cylinder above the base plate, rotate the transmission disk, drive the slider and the clamp block to move towards the center of the base plate, so that the clamp block fixes the lower spring cylinder, and the transmission between the slider and the transmission disk can be self-locked, making the fixation of the lower spring cylinder more firm.

[0015] Optionally, four chutes are formed, and four sliders and clamp blocks are provided. The four clamp blocks are arranged in a circumferential array, and a rectangular block is connected to the lower surface of the lower spring cylinder through bolts.

[0016] By adopting the above scheme, during the assembly process, the force received by the lower spring cylinder is mainly the rotational force. Just let the clamp block clamp the rectangular block, so that the clamping structure can fix the lower spring cylinder more firmly.

[0017] In summary, the present application has the following technical effects: 1. The lower spring cylinder is fixed by setting the fixing structure. The driving structure and the rotating shaft drive the volute spring to store energy, and then the upper spring cylinder and the lower spring cylinder are fixed through bolts, thus realizing the fixation of the spring cylinder; 2. By setting the worm gear and the worm, the torque required by the driving motor is reduced, enabling more energy storage of the volute spring; 3. By setting the rectangular block, the fixation of the lower spring cylinder is made more secure. Description of the Drawings

Specific implementation mode

[0020] The following further elaborates on this application in conjunction with the attached drawings.

[0021] Refer to Figure 1 and Figure 5 For the valve sector actuator spring cylinder assembly and disassembly integrated machine, it includes a frame 1. A fixing structure 2 for fixing the lower spring cylinder 9 is installed below the frame 1. A rotating shaft 3 is connected above the frame 1. The rotating shaft 3 is rotationally connected to the rotating shaft of the vane piston assembly. The rotating shaft 3 is connected to a driving motor 4 that can drive the rotating shaft 3 to rotate. When the driving motor 4 rotates, the rotating shaft 3 drives the rotating shaft of the vane piston assembly to rotate. When installing the upper spring cylinder 91 and the lower spring cylinder 9, first fix the air cylinder 92 to the upper spring cylinder 91, then fix the lower spring cylinder 9 through the fixing structure 2, place the upper spring cylinder 91 above the lower spring cylinder 9, connect the rotating shaft 3 to the rotating shaft of the vane piston assembly, and then the driving motor 4 drives the rotating shaft 3 to rotate, thereby driving the rotating shaft of the vane piston assembly to rotate, that is, driving the scroll spring to deform and store energy. Subsequently, fix the upper spring cylinder 91 and the lower spring cylinder 9 with bolts, and make the vane piston in the closed state. At this time, the stroke of the vane piston restricts the rebound of the scroll spring, so that the closed state of the vane piston is also in the energy storage state, thus realizing the installation of the upper spring cylinder 91 and the lower spring rod. When disassembling the upper spring cylinder 91 and the lower spring cylinder 9, connect the rotating shaft of the vane piston assembly to the rotating shaft 3, then remove the bolts between the upper spring cylinder 91 and the lower spring cylinder 9, and then the rotating shaft 3 drives the vane piston assembly and the scroll spring to rotate, avoiding the safety accident caused by the rebound of the scroll spring when removing the bolts.

[0022] Refer to Figure 1 and Figure 2The drive motor 4 is connected to a worm 5, which is rotatably connected to the frame 1. The worm 5 is meshed with a worm wheel 51, and the worm wheel 51 is connected to the rotating shaft 3. A through hole 511 is provided in the middle of the worm wheel 51, and the rotating shaft 3 passes through the through hole 511. The rotating shaft 3 and the worm wheel 51 are slidably connected. A reversing wheel 11 is provided above the frame 1. A steel rope 31 is fixedly connected to one end of the rotating shaft 3. The steel rope 31 passes around the reversing wheel 11, and a counterweight 32 is connected to the end of the steel rope 31 facing away from the rotating shaft 3. The counterweight 32 has the same weight as the rotating shaft 3, so that the operator only needs to lift the counterweight 32 to make the rotating shaft 3 slide downward in the through hole 511. The torque required for the volute spring to deform is relatively large. The transmission of the worm 5 and the worm wheel 51 can reduce the output torque required by the drive motor 4, so that the drive motor 4 can drive the rotating shaft 3 to rotate more smoothly. The worm wheel 51 and the worm 5 have a self-locking function to prevent the rotating shaft 3 from rotating. The rotating shaft 3 can slide up and down, which facilitates the installation of the rotating shaft 3 and the rotating shaft of the leaf piston assembly. The rotating shaft 3 can be adjusted to adapt to spring cylinders of more specifications, and the steel rope 31 will not interfere with the rotation of the rotating shaft 3.

[0023] Reference Figure 2 and Figure 3 The rotating shaft 3 is connected to a connecting block 6. One end of the connecting block 6 defines a rotating shaft groove 62 for inserting the rotating shaft of the vane piston assembly. The end of the connecting block 6 facing away from the rotating shaft defines an outer connecting groove 61. An inner connecting groove 33 is defined at one end of the rotating shaft 3. The end of the connecting block 6 defining the outer connecting groove 61 is inserted into the inner connecting groove 33 of the rotating shaft 3. The inner connecting groove 33 is polygonal in shape. When assembling spring cylinders of different specifications, only the connecting block 6 of different specifications needs to be replaced, without having to replace the rotating shaft 3. This makes the all-in-one machine more convenient for use with spring cylinders of different specifications.

[0024] Reference Figure 4, the fixed structure 2 includes a base plate 21. A transmission cavity 211 is provided inside the base plate 21. A transmission disk 22 is rotatably connected in the transmission cavity 211. A spiral tooth is provided on one side surface of the transmission disk 22. A plurality of chutes 212 pointing to the center of the circle are provided on one side surface of the base plate. The chutes 212 communicate with the transmission cavity 211, and a slider 23 is slidably connected in the chutes 212. A tooth meshing with the spiral tooth is provided on one side of the slider 23 close to the transmission disk 22. When the transmission disk 22 rotates, the slider 23 is driven to slide along the chute 212, and the slider 23 is fixedly connected with a clamping block 231 for clamping the lower spring cylinder. Four chutes 212 are provided, and four sliders 23 and clamping blocks 231 are provided. The four clamping blocks 231 are arranged in a circular array, and a rectangular block 7 is connected to the lower surface of the lower spring cylinder 9 by bolts. When fixing the lower spring cylinder 9, place the lower spring cylinder 9 above the base plate, rotate the transmission disk 22, drive the slider 23 and the clamping block 231 to move towards the center of the base plate, so that the clamping block 231 clamps the rectangular block 7, thereby fixing the lower spring cylinder 9. Moreover, the transmission between the slider 23 and the transmission disk 22 can be self-locked, making the fixation of the lower spring cylinder 9 more firm.

[0025] Refer to Figure 4 , a bevel gear is provided on the edge of the lower surface of the transmission disk 22, and the transmission disk 22 meshes with a bevel gear 8 through the bevel gear. The bevel gear 8 is fixedly connected with a wheel rod 81. One end of the wheel rod 81 passes through the transmission cavity 211 and is rotatably connected with the base plate 21, and a hand wheel 82 is fixedly arranged at one end of the wheel rod 81 passing through the transmission cavity 211. An operator can drive the bevel gear 8 to rotate by rotating the hand wheel 82, thereby driving the transmission disk 22 to rotate.

[0026] The specific implementation principle of this application is as follows: When assembling the spring cylinder, first fixedly install the upper spring cylinder 91 and the cylinder 92. Connect the rectangular block 7 and the lower spring cylinder 9 with bolts. Then place the lower spring cylinder 9 above the base plate 21. Rotate the handwheel 82 to drive the bevel gear 8 to rotate, thereby driving the transmission disk 22 to rotate. The transmission disk 22 drives the clamping block 231 to move towards the center position of the base plate 21 until the rectangular block 7 is clamped, thus fixing the lower spring cylinder 9. Then place the upper spring cylinder 91 above the lower spring cylinder 9, and connect the rotating shaft of the vane piston assembly with the central axis of the scroll spring, and insert the rotating shaft of the vane piston assembly into the shaft groove 62. Then the operator can lift the counterweight 32 to make the rotating shaft 3 slide downward in the through hole 511, so that one end of the connecting outer groove 61 of the connecting block 6 is inserted into the connecting inner groove 33 of the rotating shaft 3. Then drive the motor 4 to rotate to drive the worm 5 to rotate, thereby driving the worm gear 51, the connecting shaft of the rotating shaft 3 and the rotating shaft of the vane piston assembly to rotate, so as to drive the scroll spring to store energy. Then the operator connects the upper spring cylinder 91 and the lower spring cylinder 9 with bolts, and the valve control structure is in the state of controlling the valve to close. Then drive the electric rotation so that there is no force between the connecting shaft and the rotating shaft of the vane piston assembly. Then the connecting shaft can be removed. Then the operator rotates the handwheel 82 to separate the clamping block 231 from the rectangular block 7, removes the valve control structure, and separates the rectangular block 7 from the lower spring cylinder 9, thereby realizing the assembly of the spring cylinder.
