Description

Technical Field

[0001] The present application relates to the technical field of installation jigs, and in particular to a jig for assisting in the installation of a lock ring. Background Art

[0002] Currently, when installing a lock ring on an Adaptive Pressure Control (APC) pendulum valve, multiple lock buckles need to be raised first. Then, a worker needs to use both hands to place the lock ring under the lock buckle. Then, the multiple lock buckles need to be lowered. Then, the worker needs to use both hands to align the multiple lock buckles with the multiple lock holes on the lock ring in a narrow space. Finally, the lock ring is rotated to engage with the lock buckle, completing the installation of the lock ring.

[0003] Since there is no professional jig to assist in the installation of the lock ring, the worker needs to use both hands in a small space during installation. While keeping the lock ring in the horizontal position without deviation, the lock ring is moved upward and aligned with the lock buckle at the same time. This is inconvenient to operate, difficult to install, and has low installation efficiency.

Therefore, what is shown in the figures is schematic in nature, and their shapes are not intended to show the actual shape of the device and are not intended to limit the scope of the present application.

[0056] See attached Figure 1 , attached Figure 1 This is a schematic diagram of the structure of a lock ring 200, which includes a lock ring body 210 and a handle 220 connected to the lock ring body 210. The lock ring body 210 is generally annular and has multiple lock holes 211 evenly arranged along the circumference. The multiple lock holes 211 are located on the same circumference. The lock holes 211 have a circular first portion 2111 and a generally strip-shaped second portion 2112.

[0057] Currently, when installing the lock ring 200 on a pendulum valve, it is necessary to first raise the multiple lock buckles at the top of the pendulum valve's mounting cavity (the mounting cavity is used to install the lock ring 200). Then, a worker uses both hands to place the lock ring 200 below the lock buckles in the mounting cavity. The multiple lock buckles are then lowered, and the worker uses both hands to align the multiple lock buckles with the multiple lock holes 211 on the lock ring 200 within the narrow mounting cavity. It should be noted that when aligning the multiple lock buckles with the multiple lock holes 211 on the lock ring 200, the worker uses both hands to maintain the lock ring 200 in a horizontal position without deviation (so that the multiple lock holes 211 are located in the same plane) within the narrow mounting cavity, while moving the lock ring 200 upward and adjusting its position so that the multiple lock buckles are respectively inserted into the first portions 2111 of the multiple lock holes 211, thereby achieving alignment of the multiple lock buckles with the multiple lock holes 211. Afterwards, the handle 220 is turned to rotate the lock ring 200 so that the multiple lock buckles are respectively moved to the second parts 2112 of the multiple lock holes 211, thereby achieving the locking connection between the lock ring 200 and the lock buckles, and completing the installation of the lock ring 200.

[0058] Since there is no professional jig to assist in the installation of the lock ring 200, the worker needs to use both hands to work in a small space during installation. On the one hand, it requires a high level of physical strength from the worker, and the lock ring 200 is easily lost during installation, causing damage to the lock ring 200. On the other hand, the worker needs to keep the lock ring 200 in a horizontal position without deviation while moving the lock ring 200 upward and aligning the lock buckle. This is inconvenient to operate, difficult to install, and inefficient to install. During the alignment process, the lock ring 200 is prone to friction and collision with other components, which can easily damage the anodized coating on the outer surface of the lock ring 200. The lock ring 200 is at risk of substrate corrosion after long-term operation.

[0059] Refer to the attached Figure 2-7 The following is an exemplary description of a jig 100 for installing an auxiliary locking ring 200 according to the first embodiment of the present application. The jig 100 includes a base 110 , a guide rod 120 , a bearing 130 and an actuator 150 .

[0060] The base 110 is detachably connected to the outer wall 310 of the pendulum valve.

[0061] The guide rod 120 extends in a vertical direction and is connected to the base 110 .

[0062] The supporting member 130 is movably connected to the guide rod 120 and is configured to be movable along the extension direction (ie, vertical direction) of the guide rod 120 . The supporting member 130 has a horizontal supporting surface for supporting the locking ring 200 .

[0063] The actuator 150 is used to drive the carrier 130 to move along the extension direction of the guide rod 120, that is, to move in the vertical direction. It should be noted that the actuator 150 driving the carrier 130 to move along the extension direction of the guide rod 120 can be the actuator 150 directly driving the carrier 130 to move along the extension direction of the guide rod 120, or the actuator 150 can indirectly drive the carrier 130 to move along the extension direction of the guide rod 120 through other components (such as the guide rod 120).

[0064] According to the jig 100 for installing the auxiliary locking ring 200 of this embodiment, when installing the locking ring 200, the locking ring 200 can be supported by the horizontal supporting surface on the supporting member 130, and the supporting member 130 can be driven to rise in the vertical direction along the guide rod 120 by the actuator 150, and it is observed whether it is aligned with the falling lock buckle. If not, the position of the locking ring 200 can be adjusted by the handle 220 of the locking ring 200 to achieve the alignment of the locking hole 211 on the locking ring 200 with the lock buckle. After the locking hole 211 is aligned with the lock buckle, the locking ring 200 can be rotated to engage the locking ring 200 with the lock buckle to complete the installation of the locking ring 200. The fixture 100 for installing the auxiliary locking ring 200 according to this embodiment can replace the use of both hands to drive the locking ring 200 to move in a narrow space, so that the locking ring 200 remains in a horizontal state and moves in the vertical direction. On the one hand, it can significantly reduce the physical requirements for the staff. On the other hand, it can effectively simplify the staff's operation, reduce the difficulty of installation, and improve the installation efficiency. During the installation process, unnecessary operations can be effectively avoided to cause the locking ring 200 to collide with or rub against the internal components of the installation cavity, thereby avoiding the generation of particulate matter and damage to the anodized coating on the outer surface of the locking ring 200.

[0065] See attached Figure 2 In this embodiment, the carrier 130 includes a support base 131 and a carrier plate 132. The support base 131 is provided with a connecting portion 1311, which is sleeved on the guide rod 120 and configured to be movable along the extension direction of the guide rod 120.

[0066] In this embodiment, the guide rod 120 is a screw, and the connecting portion 1311 is a screw nut. The guide rod 120 is rotatably connected to the base 110 via a first bearing 170. For example, the outer ring of the first bearing 170 can be fixedly connected to the base 110 by means such as welding, and the lower end of the guide rod 120 can be fixedly connected to the inner ring of the first bearing 170 by means such as welding or interference fit. The central axis of the first bearing 170 extends vertically. The base 110 is generally box-shaped. The lower end of the guide rod 120 is rotatably connected to the bottom wall of the base 110 via the first bearing 170. The top wall of the base 110 is provided with an opening through which the upper portion of the guide rod 120 extends to the exterior of the base 110. The support base 131 and the carrier plate 132 are both located outside the base. The connecting portion 1311 is sleeved on the guide rod 120, and the two form a screw-nut transmission structure. When the guide rod 120 rotates, the connecting portion 1311 moves along the extension direction (i.e., the vertical direction) of the guide rod 120 (the connecting portion 1311 itself does not rotate). Exemplarily, the connecting portion 1311 can be a ball screw nut.

[0067] The carrier plate 132 is rotatably connected to the support seat 131. The carrier plate 132 has a horizontal bearing surface for supporting the lock ring 200. Specifically, the carrier plate 132 is rotatably connected to the support seat 131 via the second bearing 133. For example, the outer ring of the second bearing 133 can be fixedly connected to the support seat 131 by means such as welding, and the lower end of the carrier plate 132 can be fixedly connected to the inner ring of the second bearing 133 by means such as welding, with the central axis of the second bearing 133 extending in the vertical direction. In other embodiments, a cylindrical rotating shaft and a cylindrical sleeve extending in the vertical direction can be provided on the side of the carrier plate 132 facing the support seat 131 and the side of the support seat 131 facing the carrier plate 132, respectively. The rotating shaft is inserted into the sleeve, and the carrier plate 132 is rotatably connected to the support seat 131 via the rotating shaft and the sleeve. By rotatably connecting the carrying plate 132 and the supporting seat 131, the locking ring 200 and the carrying plate 132 can be rotated synchronously when the handle 220 on the locking ring 200 is rotated, thereby facilitating the alignment of the locking hole 211 on the locking ring 200 and the lock buckle, as well as the snap connection between the locking ring 200 and the lock buckle.

[0068] See attached Figure 2 In this embodiment, see the attached Figure 2 In this embodiment, see the attached Figure 3 In this embodiment, the carrier plate 132 is generally circular, with an arc-shaped protrusion 1321 disposed on the edge of its carrier surface. The protrusion 1321 and the carrier surface together form a receiving cavity for accommodating the lock ring body 210. The protrusion 1321 has a first end and a second end disposed opposite each other. A notch 1322 corresponding to the handle 220 is defined between the first and second ends of the protrusion 1321. This notch 1322 allows the handle 220 to extend outside the receiving cavity. When the lock ring 200 is positioned on the supporting surface and the lock ring body 210 is positioned in the receiving cavity, the inner edge of the protrusion 1321 is in contact with or substantially in contact with the outer edge of the lock ring body 210, and the ends of the protrusion 1321 are in contact with or substantially in contact with the sides of the handle 220. The protrusion 1321 limits the horizontal movement of the lock ring 200 relative to the supporting plate 132, so that the lock ring 200 and the supporting plate 132 can only rotate synchronously in the horizontal direction. In the vertical direction, the lock ring 200 can be placed on the supporting plate 132 and separated from the supporting plate 132 after being engaged with the lock buckle. The provision of the protrusion 1321 ensures that the lock ring 200 is stably placed on the supporting plate 132, preventing the lock ring 200 from shifting horizontally during installation.

[0069] See attached Figure 4In this embodiment, the outer wall 310 of the pendulum valve has four screw holes 311 on its outer side. The four screw holes 311 are used to install the pendulum valve cover plate, which can be used to enclose the installation cavity 320 located between the four screw holes 311. The base 110 is detachably connected to the outer wall 310 of the pendulum valve via two bolts 190. The two bolts 190 respectively pass through the two mounting holes on the base 110 and engage with the two screw holes 311 on the outer wall of the pendulum valve to connect the base 110 to the outer wall 310 of the pendulum valve. The relative positions of the carrier plate 132 and the base 110 can be configured such that, when the base 110 is connected to the outer wall 310 of the pendulum valve, the carrier plate 132 and the locking ring 200 located thereon are located within the mounting cavity 320, and the multiple locking holes 211 on the locking ring 200 located on the carrier plate 132 are co-circumferential with the multiple locking buckles at the top of the mounting cavity 320. That is, the projections of the multiple locking buckles on the locking ring 200 are all located on the circumference of the multiple locking holes 211. Because the protrusions 1321 can limit the horizontal movement of the locking ring 200 relative to the carrier plate 132, the locking ring 200 and the carrier plate 132 can only rotate synchronously in the horizontal direction. Therefore, when aligning the locking holes 211 on the locking ring 200 and the locking buckles, only the handle 220 needs to be rotated to achieve alignment, without the need for adjustments in other directions. This effectively simplifies the operation and reduces the difficulty of alignment. In addition, the base 110 is installed using the original screw holes 311 for installing the pendulum valve cover plate, which is conducive to the maximum and reasonable use of the original configuration.

[0070] See attached Figure 2 、 3In this embodiment, the jig 100 further includes a slide rail 160, which extends in a vertical direction. For example, the lower end of the slide rail 160 can be fixedly connected to the base 110 by means such as welding. A slider 1312 is provided at one end of the support seat 131, and the slider 1312 is slidably connected to the slide rail 160, and the guide rod 120 is located between the slider 1312 and the carrier plate 132. It should be noted that the sliding connection mentioned here means that the slider 1312 can only slide along the extension direction of the slide rail 160 relative to the slide rail 160, and cannot move in other directions. Specifically, the support base 131 includes a connecting portion 1311, a first strip plate 1313, a second strip plate 1314, and a slider 1312. The connecting portion 1311 is sleeved on the guide rod 120. The first strip plate 1313 and the second strip plate 1314 are fixedly connected to opposite sides of the connecting portion 1311. The slider 1312 is fixedly connected to an end of the first strip plate 1313 away from the connecting portion 1311. The carrying plate 132 is rotatably fixed to the second strip plate 1314 via a second bearing 133. The slider 1312 and the carrying plate 132 are respectively disposed on either side of the guide rod 120. When the supporting member 130 (i.e., the support base 131 and the carrying plate 132) moves in the vertical direction, the slider 1312 moves synchronously in the vertical direction on the slide rail 160. By setting the slider 1312 and the slide rail 160, the support member 130 can be effectively assisted in rising and falling, and a certain supporting force can be provided for the support member 130, so that the support member 130 can remain stable when moving in the vertical direction, and the end of the support seat 131 connected to the supporting plate can be prevented from being deflected due to excessive load, which can effectively extend the service life of the fixture 100.

[0071] See attached Figure 3 In this embodiment, the inner side of the slide rail 160 has a first sliding cavity extending vertically. The sliding cavity has a roughly semi-cylindrical cross-section along the vertical direction (it may also be rectangular or other suitable shapes). The slider 1312 is located in this sliding cavity and can slide vertically therein. The wall surface of the slide rail 160 facing the guide rod 120 has a strip-shaped hole extending vertically. The first strip plate 1313 passes through the strip-shaped hole and is fixedly connected to the slider 1312. In other embodiments, the inner side of the slider 1312 may have a second sliding cavity extending vertically. The slide rail 160 extends vertically and is disposed in the second sliding cavity, so that the slider 1312 can slide along the extension direction of the slide rail 160. For example, the cross-section of the slide rail 160 along the vertical direction may be a U-shaped or circular shape, and accordingly, the cross-section of the slider 1312 along the vertical direction may be a hollow rectangle or circle. The shapes and configurations of the slide rail and slider may also be other structures known to those skilled in the art, and this application does not specifically limit them.

[0072] In other embodiments, the jig 100 may be provided with a counterweight instead of the slider 1312 and the guide rail 160. The counterweight may be connected to one end of the support base 131, with the guide rod 120 positioned between the counterweight and the carrier plate 132. Specifically, the counterweight may be connected to the end of the first strip 1313 away from the connection portion 1311, on the side of the connection portion 1311 away from the second bearing 133. The counterweight can be used to balance the load, thereby maintaining the overall balance of the carrier plate 132, the locking ring 200, the support base 131, and the counterweight. This allows the carrier plate 132 and the locking ring 200 thereon to remain stable during lifting and lowering, preventing the end of the support base 131 connected to the carrier plate 132 from deflecting due to excessive load, thereby effectively extending the service life of the jig 100. For example, the counterweight may be configured to be detachably connected to one end of the support base 131.

[0073] See attached Figure 2In this embodiment, the actuator 150 includes a rocker 153 and a gear transmission structure. The rocker 153 is rotatably connected to the base 110 and is in transmission connection with the guide rod 120 via the gear transmission structure. The rocker 153 is used to drive the guide rod 120 to rotate via the gear transmission structure. When the guide rod 120 rotates, the carrier 130 moves in a vertical direction. In this embodiment, the gear transmission structure includes a first bevel gear 151 and a second bevel gear 152. The first bevel gear 151 is fixedly connected to the guide rod 120. Specifically, the first bevel gear 151 can be fixedly connected to the guide rod 120 by means such as welding. The first bevel gear 151 and the guide rod 120 are coaxially arranged. When the first bevel gear 151 rotates, it can drive the guide rod 120 to rotate synchronously. The first bevel gear 151 and the second bevel gear 152 are both located inside the base 110. The second bevel gear 152 meshes with the first bevel gear 151 and is connected to the rocker 153. Specifically, the central axis of the second bevel gear 152 can be perpendicular to the central axis of the first bevel gear 151. The second bevel gear 152 and the rocker 153 can be fixedly connected by means such as welding. The rocker 153 is used to drive the second bevel gear 152 to rotate. When the second bevel gear 152 rotates, it drives the first bevel gear 151 engaged therewith to rotate synchronously, thereby driving the guide rod 120 to rotate synchronously. The rocker 153 is rotatably connected to the base 110. Specifically, the rocker 153 includes a first rod segment 1531, a second rod segment 1532, and a third rod segment 1533 connected in sequence. One end of the first rod segment 1531 is fixedly connected to the second bevel gear 152, and the extension direction of the first rod segment 1531 is coaxial with the central axis of the second bevel gear 152. The first rod segment 1531 is rotatably connected to the side wall of the base 110 via a bearing. The second rod segment 1532 is perpendicular to the first rod segment 1531, and the third rod segment 1533 is perpendicular to the second rod segment 1532 and parallel to the first rod segment 1531. The second rod segment 1532 and the third rod segment 1533 are both located outside the base 110. Therefore, a staff member can hold the third rod segment 1533 of the rocker 153 and rotate it to drive the first bevel gear 151, thereby driving the first bevel gear 151 and the guide rod 120 to rotate synchronously, and then drive the support base 131, the carrier plate 132, and the lock ring 200 on the carrier plate 132 to move synchronously in the vertical direction. Through the arrangement of the rocker 153, the first bevel gear 151 and the second bevel gear 152, the user can control the vertical movement of the lock ring 200 by rotating the rocker 153, which is easy to operate and can avoid interference between mechanical movements of different planes (mechanical movement of the rocker 153, the support base 131 and the carrier plate 132) in a small space.

[0074] In this embodiment, the working principle of the fixture 100 is as follows:

[0075] (1) When the rocker 153 rotates, it drives the second bevel gear 152 to rotate. The second bevel gear 152 is engaged with the first bevel gear 151. When the second bevel gear 152 rotates, it drives the first bevel gear 151 to rotate synchronously.

[0076] (2) When the first bevel gear 15 rotates, it drives the guide rod 120 to rotate synchronously;

[0077] (3) Since the vertical positions of the first bearing 170 and the guide rod 120 remain unchanged, during the rotation of the guide rod 120, the support seat 131 moves synchronously in the vertical direction, thereby driving the carrier plate 132 to move synchronously in the vertical direction.

[0078] In this embodiment, the steps for installing the lock ring 200 using the fixture 100 are as follows:

[0079] (1) Turn the rocker 153 to lower the support base 131 to the lowest position;

[0080] (2) Lift the multiple lock buckles on the top of the mounting cavity 320, place the lock ring 200 on the support seat 131, and place the lock ring 200 on the bearing surface of the bearing plate 132, so that the lock ring body 210 is located in the area surrounded by the protrusion 1321 and the handle 220 is located in the notch 1322 (see the attached figure). Figure 5 ), align the mounting holes on the base 110 with the two screw holes 311 below the outer wall 310 of the pendulum valve, use the bolts 190 to pass through the mounting holes and engage with the screw holes 311 to fix the base 110 to the outer wall 311 of the pendulum valve;

[0081] (3) Lower the multiple locks on the top of the mounting cavity 320, and turn the rocker 153 with one hand to slowly raise the support seat 131, the carrier plate 132 and the lock ring 200 on the carrier plate 132 in the vertical direction (see the attached diagram). Figure 6 ), during the ascending process, observe whether the multiple lock holes 211 on the lock ring 200 are aligned with the multiple lock buckles. If not, use the other hand to rotate the handle 220 of the lock ring 200 to make fine adjustments so that the multiple lock holes 211 are aligned with the multiple lock buckles respectively;

[0082] (4) After the multiple lock holes 211 are aligned with the multiple lock buckles (that is, after the multiple lock buckles are inserted into the first parts 2111 of the multiple lock holes 211), observe whether there is any abnormality in the lock ring 200. After confirming that there is no abnormality in the lock ring 200, turn the handle 220 (see Appendix Figure 7 ), so that the multiple lock buckles are respectively moved into the second parts 2112 of the multiple lock holes 211, completing the engagement between the lock ring 200 and the lock buckles;

[0083] (5) Turn the rocker 153 to lower the support base 131 and the carrier plate 132 in the vertical direction, separate the carrier plate 132 from the lock ring 200, loosen the bolts 190 connecting the base 110 and the outer wall 310 of the pendulum valve, and evacuate the fixture;

[0084] (6) Adjust the air valve of the pendulum valve several times to control the lifting of the lock ring 200 and confirm the installation effect of the lock ring 200.

[0085] Refer to the attached Figure 8 The fixture 100 ′ for mounting the auxiliary locking ring 200 according to the second embodiment of the present application is exemplified. The fixture 100 ′ differs only in the actuator 150 ′ from the actuator 150 of the first embodiment, and the rest of the components are the same as those of the first embodiment, which will not be described again.

[0086] In this embodiment, the actuator 150' includes a rocker 154 connected to the guide rod 120. The rocker 154 is used to drive the guide rod 120 to rotate. When the guide rod 120 rotates, the support member 130 moves vertically. Specifically, the rocker 154 includes a first segment 1541, a second segment 1542, and a third segment 1543, which are sequentially connected. The first segment 1541 is fixedly connected to the lower end of the guide rod 120 and is coaxial with the guide rod 120. The second segment 1542 is perpendicular to the first segment. The third segment 1543 is perpendicular to the second segment 1542 and parallel to the first segment 1541. Therefore, a worker can grasp the third segment 1533 of the rocker 154 and rotate it, directly driving the guide rod 120 to rotate synchronously, thereby driving the support base 131, the support plate 132, and the locking ring 200 on the support plate 132 to move synchronously in the vertical direction.

[0087] The steps of installing the lock ring 200 using the jig 100 ′ are substantially the same as those of the first embodiment, and will not be repeated here.

[0088] Refer to the attached Figure 9 An exemplary description is given of a jig 100 ″ for installing an auxiliary locking ring 200 according to the third embodiment of the present application. The jig 100 ″ differs from the actuating device 150 of the first embodiment only in the actuating device 150 ″, and the other parts are the same as those of the first embodiment, which will not be repeated here.

[0089] In this embodiment, the actuator 150 ″ includes a motor 155. The output shaft 1551 of the motor 155 is connected to the guide rod 120. The motor 155 is used to directly drive the guide rod 120 to rotate. When the guide rod 120 rotates, the bearing member 130 is driven to move in the vertical direction. Specifically, the output shaft 1551 of the motor 155 can be fixedly connected to the lower end of the guide rod 120 and coaxial with the guide rod 120. Therefore, when the output shaft 1551 of the motor 155 rotates, it can drive the guide rod 120 to rotate synchronously.

[0090] The steps for installing the lock ring 200 using the jig 100" are substantially the same as those of the first embodiment, except that in steps (3) and (5), it is necessary to control the forward and reverse rotation of the motor 155 to drive the guide rod 120 to rotate synchronously, so that the support seat 131 and the carrier plate 132 can be raised and lowered in the vertical direction. Using the motor 155 to drive the guide rod 120 to rotate can further save the staff's effort and reduce the difficulty of operation compared to using the rocker 153 to drive the guide rod 120 to rotate.

[0091] Refer to the attached Figure 10 An exemplary description is given of a jig 100'' for installing an auxiliary locking ring 200 according to a fourth embodiment of the present application. The jig 100'' differs from the actuating device 150'' of the first embodiment only in its actuating device 150''; the other parts are the same as those of the first embodiment and will not be repeated here.

[0092] In this embodiment, the actuator 150 ' includes a motor 156 and a transmission structure. The output shaft 1561 of the motor 156 is connected to the guide rod 120 through the transmission structure. The motor 156 is used to drive the guide rod 120 to rotate through the transmission structure. When the guide rod 120 rotates, the bearing member 130 is driven to move in the vertical direction. Exemplarily, the transmission structure is a gear transmission structure. The gear transmission structure may include a first bevel gear 157 and a second bevel gear 158. The first bevel gear 157 is fixedly connected to the guide rod 120 and is coaxially arranged with the guide rod 120. When the first bevel gear 157 rotates, it can drive the guide rod 120 to rotate synchronously. The first bevel gear 157, the second bevel gear 158 and the motor 156 can all be located inside the base 110. The second bevel gear 158 is connected to the first bevel gear 157 and the second bevel gear 158. A bevel gear 157 is meshed with and connected to the output shaft 1561 of the motor 156. A second bevel gear 158 can be coaxially arranged with the output shaft 1561. When the output shaft 1561 of the motor 156 rotates, the second bevel gear 158 is driven to rotate. When the second bevel gear 158 rotates, the first bevel gear 157 meshed with it is driven to rotate synchronously, thereby driving the guide rod 120 to rotate synchronously. In other embodiments, the transmission structure can be a belt transmission structure, which can include two pulleys fixedly connected to the guide rod 120 and the output shaft 1561 of the motor 156, respectively, and a belt tensioned on the two pulleys. The output shaft 1561 of the motor 156 is connected to the guide rod 120 via the transmission structure, which allows for more flexible configuration of the installation position of the motor 156.

[0093] The steps for installing the lock ring 200 using the jig 100″ are substantially the same as those of the first embodiment, except that in steps (3) and (5), it is necessary to control the forward and reverse rotation of the motor 156 to drive the guide rod 120 to rotate synchronously so that the support seat 131 and the carrier plate 132 can be raised and lowered in the vertical direction. Using the motor 156 and the transmission structure to drive the guide rod 120 to rotate can further save the staff's effort and reduce the difficulty of operation compared to using the rocker 153 to drive the guide rod 120 to rotate.

[0094] In some other embodiments, the guide rod 120 may be a polished rod extending in the vertical direction, and the connecting portion 1311 may be a sleeve mounted on the polished rod, and the connecting portion 1311 may be movable along the extension direction of the guide rod 120. The actuator is connected to the carrier 130 and is used to directly drive the carrier 130 to move in the vertical direction. Exemplarily, the actuator may include a linear actuator fixedly arranged on the base 110, such as a cylinder, etc., the output end of which is directly connected to the carrier 130 to drive the carrier 130 to move in the vertical direction. The other parts of the carrier 130 except the connecting portion may be the same as those in the above embodiment and will not be repeated here.
