Description

Technical Field

[0001] The invention belongs to the technical field of pole-mounted switches, and in particular relates to an auxiliary maintenance mechanism for pole-mounted switches. Background Art

[0002] Pole-mounted switches are installed on utility poles to ensure electrical safety. Their primary function is to isolate high voltage circuits. They differ significantly in function, structure, and application scenarios, each playing a unique role in the power system, collectively maintaining the safety and stability of the grid. However, to ensure grid security, pole-mounted switches require regular maintenance and inspection to prevent damage, which could compromise grid safety.

[0003] Publication number: CN116031084A, discloses a pole-mounted switch that is easy to maintain. It includes a supporting bracket installed between the main pole and the auxiliary pole, with the supporting bracket installed on the pole-mounted switch; the main pole is provided with a maintenance mechanism for flipping and lifting the supporting bracket; the supporting bracket includes a main mounting frame for installing circuit breakers and current transformers, with mounting brackets for installing voltage transformers provided on both sides of the main mounting frame; an intelligent feeder unit is installed on one side of the lower part of the main pole through a clamp; the auxiliary pole is provided with a support frame overlapped with the front end of the main mounting frame on the side close to the supporting bracket. The present invention can realize efficient and convenient flipping and lifting operations of the pole-mounted switch by organically combining the maintenance mechanism and the supporting bracket with the pole-mounted switch; thereby allowing workers to complete the maintenance or component replacement of the pole-mounted switch on the ground or at a lower level; while improving maintenance efficiency, it also greatly reduces the safety risks of workers.

[0004] However, there are some problems with the existing technology: Although the above-mentioned prior art can flip the pole switch and lower it, lowering the position of the pole switch, making it easier for staff to complete the inspection and maintenance of the pole switch on the ground or at a lower place, the above-mentioned technology still has the following problems: First, a special electric pole is required, which changes the original stable support of the electric pole, easily affecting the stable support of the pole switch by the electric pole, and the manufacturing cost of the special electric pole is high, and there are certain limitations. Secondly, the pole switch uses a pulley rope method to change the position of the pole switch. Although it is convenient to lift and lower the pole switch for convenient maintenance, the service life of the rope is limited, and the pole switch needs to be hoisted for a long time. This leads to the need to check the use of the rope during daily inspection and maintenance of the pole switch, which undoubtedly increases the workload of the staff and cannot meet the current situation. Therefore, we propose an auxiliary maintenance mechanism for the pole switch. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an auxiliary maintenance mechanism for pole-mounted switches. Through the installation method of the auxiliary power-off component, the lifting component and the anti-fall component, a sleeve installation method is adopted. Therefore, there is no need to change the shape and state of the electric pole itself to realize the lifting and lowering of the pole-mounted switch, thereby reducing the cumbersomeness of the installation of the lifting component that controls the lifting and lowering of the pole-mounted switch. Secondly, the mutual cooperation between the speed limiter and the anti-fall component can avoid the method of using a steel rope to lift the pole-mounted switch, which requires additional steps to inspect the steel rope, thereby effectively reducing the workload of the staff.

[0021] 2. Through the cooperation between the speed limiter and the anti-fall component, this application still uses the pulley method to lift the switch on the column, which is convenient for the staff to perform maintenance work on the column switch directly at a lower level or on the ground. At the same time, through the cooperation between the speed limiter and the anti-fall component, it can be prevented that the column switch falls and is damaged when the steel rope breaks, and there is no need for the staff to inspect the steel rope when maintaining the column switch. Therefore, the method of using the steel rope to lift the column switch can be avoided, which requires the additional step of inspecting the steel rope.

[0022] 3. When the steel rope breaks, the limiter can become the second safety measure for the positioning sleeve and the lifting sleeve. When the limiter is triggered, the anti-fall component can be linked to prevent the pole switch from falling and being damaged.

[0023] 4. The installation method of the auxiliary power-off assembly, lifting assembly and anti-fall assembly all adopts the sleeve installation method. Therefore, there is no need to change the shape and state of the pole itself to realize the lifting and lowering of the pole switch, thereby reducing the cumbersomeness of installing the lifting assembly that controls the lifting and lowering of the pole switch.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figures 1 to 16As shown, an auxiliary maintenance mechanism for a pole-mounted switch provided by an embodiment of the present invention comprises: two groups of pole bodies 1 and a switch mechanism 2 slidably sleeved on the outside of the pole body 1, the switch mechanism 2 being composed of a switch base plate 201, a lifting plate 202, a pole-mounted circuit breaker 203 and a plurality of insulating columns 204, the lifting plate 202 being slidably sleeved between the two groups of pole bodies 1, the switch base plate 201 being arranged on the upper surface of the lifting plate 202, and the pole-mounted circuit breaker 203 being arranged on the upper surface of the switch base plate 201, a plurality of insulating columns 204 being respectively arranged at the four corners of the upper surface of the switch base plate 201, and a conductor 3 being arranged on the upper surface of each group of insulating columns 204, the upper ends of the outer sides of the two groups of pole bodies 1 being fixedly sleeved with a cable bracket 4, the cable bracket 4 being sleeved on the outer side of the conductor 3; an auxiliary power-off component 9, two groups of the auxiliary power-off components 9 being provided, and the auxiliary power-off component 9 The auxiliary power-off assembly 9 is arranged in pairs with the utility pole body 1. The auxiliary power-off assembly 9 consists of an insulating switch component 901, a linkage component 902, and a docking and fixing component 903. The linkage component 902 is arranged between the docking and fixing component 903 and the insulating switch component 901, and the docking and fixing component 903 and the insulating switch component 901 are both transmission-connected to the linkage component 902. A docking gasket 18 is provided at one end of the wire 3. The docking and fixing component 903 is arranged on one side of the utility pole body 1, and the docking gasket 18 is detachably connected to the upper surface of the insulating column 204 through the docking and fixing component 903. The insulating switch component 901 is arranged on one side of the lifting plate 202. Both ends of one side of the pole-mounted circuit breaker 203 are provided with a power-on crank 6 for controlling the current. The insulating switch component 901 is movably connected to the power-on crank 6, and the power-on crank 6 is repeatedly rotated by the insulating switch component 901.

[0045] Through the design that the docking fixing component 903 and the insulating switch component 901 are both transmission-connected with the linkage component 902, when the docking fixing component 903 cancels the extrusion of the docking gasket 18, the linkage component 902 can transmit the insulating switch component 901, control the power crank 6 to rotate or repeatedly rotate, and realize the power-off operation. Therefore, through the linkage component 902, the preparation work before the maintenance of the pole switch can be quickly completed, thereby effectively improving the maintenance efficiency of the pole switch.

[0046] The anti-fall component 11 and the lifting component 10 are each provided with two groups, and the two groups of anti-fall components 11 are respectively detachably mounted on the upper ends of the outer sides of the two groups of pole bodies 1, and the lifting component 10 is fixedly mounted on the upper ends of the outer sides of the pole bodies 1, and the anti-fall component 11 is arranged below the upper ends of the lifting components 10, and the lifting component 10 is fixedly connected to the lifting plate 202, so that the lifting plate 202 is lifted and lowered on the outer sides of the pole body 1 through the lifting component 10.

[0047] like Figures 1 to 16As shown, the anti-fall component 11 is designed to be arranged below the upper end of the lifting component 10. The upper end of the lifting component 10 serves as a fulcrum, and the wheel group is used to realize the lifting and lowering of the lifting plate 202. The upper end of the lifting component 10 serves as a fulcrum and is subjected to severe force. Therefore, the anti-fall component 11 is arranged below the upper end of the lifting component 10. When the upper end of the lifting component 10 falls off from the pole body 1, it can prevent the upper end of the lifting component 10 from falling directly. The anti-fall component 11 can serve as a second line of defense, effectively preventing the lifting component 10 from being damaged by hanging the pole switch for a long time, causing the pole switch to fall suddenly and be damaged.

[0048] In summary, the installation methods of the auxiliary power-off component 9, the lifting component 10 and the anti-fall component 11 all adopt a sleeve installation method. Therefore, there is no need to change the shape and state of the pole body 1 itself to realize the lifting and lowering of the pole switch, thereby reducing the cumbersomeness of the installation of the lifting mechanism that controls the lifting and lowering of the pole switch.

[0049] Furthermore, the insulating switch component 901 includes a pull rod 9011 and a base 9012. The base 9012 is fixedly mounted on one side of the lifting plate 202. A movable seat 25 is slidably connected to the upper surface of the base 9012. The movable seat 25 is rotatably connected to the pull rod 9011. The power crank 6 is slidably sleeved on the outside of the pull rod 9011. One end of the movable seat 25 is rotatably connected to a connecting rod 9013. Both ends of one side of the lifting plate 202 are fixedly mounted with a sliding bearing plate 9014. The upper surface of the sliding bearing plate 9014 is slidably connected to a sliding seat 9015. The sliding seat 9015 is rotatably connected to the connecting rod 9013. The sliding seat 9015 is transmission-connected to the linkage component 902.

[0050] like Figures 1 to 16 As shown, by the design that the power crank 6 is slidably sleeved on the outside of the pull rod 9011, the connecting rod 9013 moves, and the pull rod 9011 can be controlled to slide downward along the inclined direction of the base 9012 through the movable seat 25, thereby realizing the rotation of the power crank 6, realizing power off or releasing the stored energy inside the switch.

[0051] Furthermore, the docking fixing component 903 includes two groups of fixed cover plates 9034, and a docking pad 19 is provided on the upper end of the insulating column 204. The docking pad 19 is composed of a bottom plate and a docking column fixedly connected to the center of the upper surface of the bottom plate, and one side of the docking column is arranged in an arc shape. Both ends of the upper surface of the fixed cover plate 9034 are provided with fixing holes. The fixed cover plate 9034 is sleeved on the outer side of the docking column through the fixing holes.

The bottom of the driven gear 9032 is meshed and connected to the driving gear 9033. Both sides of the driving gear 9033 are rotatably connected to the first side mounting plate 20. The fixed cover plate 9034 is rotatably connected to the insulating column 204; the outer sliding sleeve of the pole body 1 is provided with a lifting sleeve 5. The lifting sleeve 5 is correspondingly arranged at the bottom of the anti-fall assembly 11, the lifting sleeve 5 is fixedly connected to the lifting plate 202, and a protective shell 9036 is fixedly connected to one side of the lifting sleeve 5. A second synchronization mechanism 9035 is arranged inside the protective shell 9036, and both ends of the second synchronization mechanism 9035 are transmission-connected with a second linkage rod 9031. One end of the second linkage rod 9031 passes through one side of one group of first side mounting plates 20, and one end of the second linkage rod 9031 is fixedly connected to the driving gear 9033. One end of the second synchronization mechanism 9035 is transmission-connected to the linkage component 902. A driving assembly 21 is provided at one end of one side of the protective shell 9036, and the driving assembly 21 is transmission-connected to the other end of the second synchronization mechanism 9035, and the driving assembly 21 is used to drive the second synchronization mechanism 9035;

[0052] Specifically, such as Figures 10 to 13As shown, the driving assembly 21 mentioned above includes a hollow frame 2103, a ratchet mechanism 2107 and a remote control motor 2105. The hollow frame 2103 is fixedly connected to the protective shell 9036, and a avoidance hole is provided on one side of the protective shell 9036, and the avoidance hole corresponds to the inside of the hollow frame 2103. One side of the hollow frame 2103 is slidably connected to the mobile shell 26. The ratchet mechanism 2107 is arranged inside the mobile shell 26, and the outer side of the remote control motor 2105 is fixedly connected to the mobile shell 26. The center of one side of the ratchet mechanism 2107 and one end of the output shaft of the remote control motor 2105 are both transmission-connected with the docking shaft 2104, and the other end of the second synchronization mechanism 9035 is transmission-connected with the docking block 2106. The two groups of docking shafts 2104 are both provided with square grooves on the same side, and the two groups of square grooves are arranged opposite to each other. One end of one side of the hollow frame 2103 is provided with an electric The electric adjustment mechanism 2101 is driven, and the outer side of the remote control motor 2105 is transmission connected to the electric adjustment mechanism 2101. The center of one side of the movable shell 26 is rotatably connected to the rotating crank 2108, and the rotating crank 2108 is transmission connected to the ratchet mechanism 2107. The bottom of the rotating crank 2108 is fixedly installed with an adjusting rod 2102. The lower ends of both sides of the adjusting rod 2102 are slidably connected to the connecting plates 22, and the opposite sides of the two groups of connecting plates 22 are rotatably connected to the second side mounting plates 24. Another group of adjusting rods 2102 is fixedly installed between the two groups of second side mounting plates 24, and the upper end of the other group of adjusting rods 2102 is fixedly installed with a second card joint 23. A card slot is opened at the lower end of one group of adjusting rods 2102, and the second card joint 23 is engaged in the card slot. The other group of adjusting rods 2102 is detachably connected to the lower end of the outer side of the pole body 1 by bolts.

[0053] It should be noted that the electric adjustment mechanism 2101 mentioned above adopts a screw transmission method, and the technical means of using a screw to control the horizontal movement of an object has become an existing mature technology. Therefore, the present invention will not be described in detail here.

[0054] In addition, it should be noted that the ratchet mechanism 2107 mentioned above is composed of a ratchet and a pawl, and the pawl is rotatably connected to the rotating crank 2108. Therefore, the two sets of adjustment rods 2102 can be docked into one by sliding and rotating. By repeatedly shaking the adjustment rod 2102, the docking shaft 2104 can be rotated through the ratchet mechanism 2107. When the docking shaft 2104 connected to the ratchet mechanism 2107 is docked with the docking block 2106, by shaking the adjustment rod 2102, the fixed cover 9034 can be flipped and the power-off operation of the pole-mounted circuit breaker 203 can be achieved through the second synchronization mechanism 9035 and the linkage component 902.

[0055] Through the design of the ratchet mechanism 2107 and the remote control motor 2105, a method of manually and automatically driving the second synchronization mechanism 9035 transmission is realized, so that the best solution can be adopted to disconnect the wire 3 from the insulating column 204 and to cut off the power of the pole circuit breaker 203 according to the weather conditions for maintenance of the pole switch.

[0056] like Figures 1 to 16 As shown, through the arc-shaped design on one side of the docking column, when the fixed cover plate 9034 rotates around the driven gear 9032, the inner wall of the fixing hole can perfectly fit the outer side of the docking column, thereby achieving a more stable fixation of the docking gasket 18 on the docking pad 19.

[0057] By setting up the second synchronization mechanism 9035, the drive assembly 21 can cooperate with the second synchronization mechanism 9035 to simultaneously control the rotation of two groups of second linkage rods 9031 on the same side, so that the docking gasket 18 used to connect multiple groups of wires 3 is separated from the docking pad 19, thereby improving the preparation work before the pole-mounted switch is lowered for maintenance.

[0058] Furthermore, the linkage component 902 includes a bevel gear linkage mechanism 9027 and a first synchronization mechanism 9023. The bevel gear linkage mechanism 9027 is transmission-connected to the second synchronization mechanism 9035. A mounting shell 9021 is fixedly mounted on one end of the upper surface of the sliding carrier plate 9014. The second synchronization mechanism 9035 is disposed inside the mounting shell 9021. A first linkage rod 9022 is disposed between the bevel gear linkage mechanism 9027 and the first synchronization mechanism 9023. Thus, the bevel gear linkage mechanism 9027 is connected to the first synchronization mechanism 9035 via the first linkage rod 9022. 23 transmission connection, one end of the bottom of the first synchronization mechanism 9023 is transmission-connected to the transmission housing 9024, the bottom of the transmission housing 9024 is hollow, the upper surface of the sliding bearing plate 9014 is provided with a sliding groove, the lower end of the sliding seat 9015 is slidably installed inside the sliding groove, and a pull rope 9016 is fixedly installed at the lower end of one side of the sliding seat 9015. A winding wheel 9025 is provided at the lower end of the transmission housing 9024, one end of the pull rope 9016 is wound around the outside of the winding wheel 9025, and the winding wheel 9025 is rotatably installed inside the sliding groove; a lower part inside the sliding groove A reset groove is provided at the end, and a positioning rod 9026 is fixedly installed at the bottom of the winding wheel 9025. One end of the positioning rod 9026 extends into the reset groove. A reset spring 7 is fixedly installed on the inner wall of the reset groove, and the reset spring 7 is fixedly connected to the positioning rod 9026; a groove 8 is provided inside the transmission housing 9024, and a push plate 13 is elastically connected inside the groove 8. One end of the two sides of the push plate 13 is relatively inclined. A transmission rod 14 is fixedly installed in the middle of the upper surface of the winding wheel 9025, and a force plate 15 is fixedly installed on the outside of the transmission rod 14, and the force plate 15 is fixedly installed on the outside of the transmission rod 14. 5 is arranged corresponding to the push plate 13, one end of the force-bearing plate 15 is rounded, one end of the positioning rod 9026 passes through the lower part of the reset groove to the bottom of the sliding support plate 9014, and a protrusion is fixedly installed on the lower end of the outer side of the positioning rod 9026, and the upper surface of the protrusion is rotatably connected to the fixing plate 16, and the fixing plate 16 is fixed to the protrusion by bolts. A first clamping joint 17 is fixedly installed on one side of the fixing plate 16, and a baffle 12 is fixedly installed on one end of the bottom of the sliding support plate 9014. A clamping groove is opened on one side of the baffle 12, and the first clamping joint 17 is clamped inside the clamping groove;

[0059] like Figures 1 to 15 As shown, the force-bearing plate 15 and the pushing plate 13 are designed to be arranged in correspondence, and the inclined side of the end of the pushing plate 13 contacts the force-bearing plate 15, and then the force-bearing plate 15 is pushed, and the winding wheel 9025 is driven to rotate through the transmission rod 14. At this moment, when the winding wheel 9025 rotates, it will reel in the pull rope 9016, so that the pull rope 9016 drives the sliding seat 9015 to slide, and the sliding seat 9015 cooperates with the connecting rod 9013, the base 9012 and the pull rod 9011 to realize the rotation of the power crank 6 and perform the power-off operation.

[0060] By setting the baffle 12 and the design that the lower end of the positioning rod 9026 extends to the bottom of the sliding bearing plate 9014, when the winding wheel 9025 rotates, it can drive the positioning rod 9026 to rotate, and the positioning rod 9026 drives the protrusion to rotate. Then, after the protrusion rotates to a certain position, it will contact the baffle 12. At this time, the positioning rod 9026 cannot rotate, and the push plate 13 continues to rotate. The transmission rod 14 is not subjected to the thrust for an instant, and the transmission rod 14 will be rotated by the force of the reset spring 7. At this moment, the pull rod 9011 will be reset, and then continue to contact with the push plate 13, so that the pull rod 9011 can repeatedly pull the power crank 6 to release the stored energy inside the switch.

[0061] It is worth noting that the two power cranks 6 on the pole-mounted circuit breaker 203 correspond to the switch for releasing the energy stored inside the switch and the power-off switch respectively. To release the switch for releasing the energy stored inside the switch, the power crank 6 needs to be repeatedly rotated, while the power-off switch only needs to be rotated once. The positioning rod 9026 used for the position where the power crank 6 only needs to be rotated once, and the fixed plate 16 connected to the convex point extending from the positioning rod 9026 is rotated, and the fixed plate 16 is flipped to a vertical state and fixed at an angle by bolts. When the positioning rod 9026 drives the convex point to contact the baffle 12, the first clamping joint 17 is engaged in the clamping groove, and the positioning rod 9026 will be unable to rotate. Therefore, after the power crank 6 that only needs to be rotated once is rotated, the angle is fixed and it will not be rotated repeatedly.

[0062] It should be noted that the connection between the power crank 6 and the pole-mounted circuit breaker 203 is equipped with a torsion spring to achieve automatic rotation. The power crank 6 can rotate on the pole-mounted circuit breaker 203, which is already a mature technology. Therefore, the present invention will not be elaborated here.

[0063] In summary, through the mutual cooperation of the baffle 12, the push plate 13, the force plate 15, the positioning rod 9026 and the reset spring 7, when the fixed cover 9034 is flipped open, the stored energy inside the pole-mounted circuit breaker 203 switch can be released and the power-off operation can be performed at the same time, so that the preparation work before the pole-mounted switch is lowered can be completed quickly, thereby improving the maintenance efficiency of the pole-mounted switch.

[0064] Furthermore, the lifting assembly 10 includes a positioning sleeve 101 and an automatic reel 105. The positioning sleeve 101 is fixedly mounted on the upper end of the outer side of the pole body 1. A pulley 102 is rotatably connected to one side of the positioning sleeve 101. A steel rope 103 is wound around the outer side of the automatic reel 105. The steel rope 103 passes over the top of the pulley 102 and is fixedly connected to the lifting sleeve 5. A speed limiter 104 is provided between the positioning sleeve 101 and the lifting sleeve 5.

[0065] like Figures 1 to 16As shown, by the design of the speed limiter 104, the lifting speed of the lifting sleeve 5 can be controlled, thereby preventing the lifting sleeve 5 from falling instantly when the steel rope 103 breaks, causing damage to the pole switch.

[0066] Furthermore, the anti-fall assembly 11 includes a positioning ring 1101 and multiple groups of extrusion plates 1102. The positioning ring 1101 is detachably sleeved on the outside of the pole body 1 by bolts. The multiple groups of extrusion plates 1102 are arranged in an annular shape with equal spacing, and the extrusion plates 1102 are rotatably connected to the positioning ring 1101. The lower end of one side of the extrusion plate 1102 is arranged in an arc shape corresponding to the pole body 1; multiple groups of stabilizing grooves are provided on the outside of the positioning ring 1101, and the multiple groups of stabilizing grooves are arranged in an annular shape with equal spacing. Multiple groups of plug-in rods 1103 are fixedly installed on the bottom of the positioning ring 1101. The plug-in rods 1103 are connected to the positioning ring 1101. 3 is slidably inserted into the stable groove. A rotating rod 1107 is fixedly installed on the upper surface of the extrusion plate 1102, and the rotating rod 1107 is rotatably connected to the bottom of the positioning ring 1101. A pressure rod 1105 is fixedly installed at both ends of the rotating rod 1107. The opposite ends of the pressure rod 1105 and the plug rod 1103 are arranged to be inclined and fit each other. The plug rod 1103 is slidably arranged in the stable groove with the rotating rod 1107 as the central axis. Multiple groups of extension slides 1106 are fixedly installed on the outside of the positioning ring 1101, and the plug rod 1103 is slidably connected to the extension slides 1106.

[0067] like Figures 1 to 16 As shown, through the design that the opposite ends of the pressure rod 1105 and the connecting rod 1103 are arranged in an inclined manner to fit each other, when the steel rope 103 labor positioning sleeve 101 descends, the positioning sleeve 101 descends and drives the connecting rod 1103 to squeeze the pressure rod 1105, and the pressure rod 1105 rotates around the rotating rod 1107, and drives the extrusion plate 1102 to squeeze the pole body 1, thereby increasing friction and improving the stability of the positioning ring 1101 on the outside of the pole body 1, thereby effectively preventing the positioning sleeve 101 from falling off at the installation position and causing the switch on the pole to fall and be damaged.

[0068] Specifically, such as Figure 15 As shown, multiple groups of aluminum I-plates 1104 are arranged between the positioning sleeve 101 and the positioning ring 1101. When the positioning sleeve 101 drops, the aluminum I-plates 1104 serve as the first line of defense to prevent the positioning sleeve 101 from dropping instantly and generating a large impact force on the positioning ring 1101, thereby affecting the means of increasing the friction of the multiple groups of extrusion plates 1102. The middle part of the aluminum I-plates 1104 is in a curved state, which can buffer the pressure of the instantaneous drop of the positioning sleeve 101, thereby achieving a stable increase in friction of the multiple groups of extrusion plates 1102, further improving the stability of the positioning ring 1101 after installation and the stability of the pole switch after maintenance after installation.

[0069] In summary, it should be noted that the first synchronization mechanism 9023 and the second synchronization mechanism 9035 in the present invention both adopt a transmission method of two sets of synchronization wheels and a synchronization belt to achieve the purpose of synchronous transmission. The transmission method of two sets of synchronization wheels and a synchronization belt to achieve the purpose of synchronous transmission has become an existing mature technical means. Therefore, the present invention will not elaborate on it here.

[0070] In addition, the bevel gear linkage mechanism 9027 mentioned above adopts the method of two sets of bevel gears meshing with each other to realize reversing transmission, so that the second synchronization mechanism 9035 can drive the first linkage rod 9022 to rotate through the bevel gear linkage mechanism 9027. The method of two sets of bevel gears meshing with each other to realize reversing transmission is already a mature transmission technology means. Therefore, the present invention will not elaborate on it here.

[0071] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that, without departing from the principles of the present invention, a number of improvements and modifications may be made to the present invention by those skilled in the art, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
