[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "side", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0028] The present invention provides a first embodiment of a compatibility device applied to a pole-mounted switch. Refer to Figure 1 And Figure 2 , the compatibility device includes: a bottom plate 1, a first support plate 2, a second support plate 3, a first adjustment mechanism 4, a second adjustment mechanism 5, and a clamping mechanism 6; wherein, the clamping mechanism 6 is two clamping components with the same height and arranged oppositely, and a clamping space is formed between the two clamping components; the size of the clamping space will be adjusted according to the sizes of pole-mounted switch products of different models. In the current technology, due to the limitation of the clamping mechanism 6 or the lack of corresponding adjustment mechanisms, the clamping mechanism 6 cannot be compatible with pole-mounted switches of different model sizes, thereby restricting the automated production process.

[0029] In this embodiment, the bottom plate 1 is arranged at the bottom of the compatibility device and is used to support the compatibility device; its load-bearing range is greater than the sum of the weight of the pole-mounted switch and the weights of all the mechanisms arranged above it.

[0030] Among them, the first support plate 2 is arranged directly above the bottom plate 1 and is fixedly connected to the bottom plate 1. Considering that the size specifications of pole-mounted switches of different models vary greatly, such as pole-mounted switches of different models such as ZW20, ZW32, ZW68, etc., the length range spans 350mm - 1200mm. In this embodiment, it is preferably set that the length range of the first support plate 2 is 1300 - 1800mm; since the longest length of the pole-mounted switch is 1200mm, plus the thickness of the clamping mechanism 6, appropriate machining positions are reserved, and costs, etc., it is most suitable to set the length range of the first support plate 2 to 1400, and it is applicable to the use of pole-mounted switches of any model. If a range greater than 1800mm is adopted, although the universality is stronger, it is not conducive to on-site installation in the production and cost control.

[0031] In this embodiment, the first adjustment mechanism 4 is arranged directly above the first support plate 2; the first adjustment mechanism 4 includes: a transmission component 41, a transmission component 42, and a guiding component 43. Among them, the transmission component 42 includes: a transmission unit and a connection unit.

[0032] Among them, the transmission component 41 is an electric transmission component, a manual transmission component, or a combination of both. In this embodiment, a combination of an electric transmission component and a manual transmission component is preferably used as the transmission component 41. For specific reference, see Figure 3 and Figure 4 , the electric transmission component is composed of a flange coupling 411, a first motor 412, and a synchronous belt transmission unit 413. The synchronous belt transmission unit 413 has the following advantages: high strength, high rigidity, wear resistance, high temperature resistance, corrosion resistance; having an accurate transmission ratio and stable transmission performance; the belt has good flexibility and elasticity, smooth transmission, and low noise; when overloaded, the belt slips on the pulley to protect the prime mover; it does not require frequent adjustment of the tension, is convenient for maintenance, and has low operating costs. The synchronous belt does not require lubrication, and the maintenance cost is relatively considerable. Among them, the manual transmission component is composed of a handle, and the handle is connected to one end of the transmission mechanism 42 through a corresponding connecting piece; by adding a manual transmission method, it can provide further guarantee for the implementation of the transmission process.

[0033] See Figure 1 , the transmission component 41 is arranged on one side of the compatibility device bottom plate; the transmission unit of the transmission component 42 is connected to the transmission component 41, and the connection unit is fixedly connected to the bottom of the second support plate 3; the guiding component 43 is arranged on both sides of the first support plate 2 to provide a place for opposite / backward movement; the highest point of the guiding component 43, the highest point of the transmission component 42 are flush with the bottom surface of the second support plate 3.

[0034] In this embodiment, the transmission component 42 is preferably a bidirectional lead screw. If other components with similar or the same functions as the bidirectional lead screw are used, they are all within the protection scope of the present invention. Among them, the guiding component 43 is a combination of a track and a slider, or a combination of a track and a roller. The method adopted in the illustration of this embodiment is a combination of a track and a slider.

[0035] In this embodiment, the second support plate 3 is arranged directly above the first adjustment mechanism 4, one end of which is fixedly connected to the first adjustment mechanism 4, and the other end is fixedly connected to the bottom of the clamping mechanism 6; the first adjustment mechanism 4 is used to transmit the action through the second support plate 3 to make the clamping mechanism 6 perform horizontal opposite / backward movement, and adjust the relative size of the clamping space of the clamping mechanism 6.

[0036] This embodiment uses a specific example to elaborate in detail on the transmission method of the first adjustment mechanism 4. Specifically, refer to Figure 5 , as shown in the figure, if it is currently necessary to reduce the size of the clamping space, it is necessary to control the first motor 412 to drive counterclockwise, and then drive the bidirectional lead screw to move towards each other through the synchronous belt transmission unit 413, so that the clamping mechanism 6 moves towards each other. Similarly, if it is currently necessary to increase the size of the clamping space, it is necessary to control the first motor 412 to drive clockwise, and then drive the bidirectional lead screw to move away from each other through the synchronous belt transmission unit 413, so that the clamping mechanism 6 moves away from each other. If the manual control method is adopted, the handle is driven to rotate counterclockwise, thereby driving the bidirectional lead screw to move towards each other; on the contrary, the handle is driven to rotate clockwise, thereby driving the bidirectional lead screw to move away from each other.

[0037] In this embodiment, the second adjustment mechanism 5 is arranged on the side of the clamping mechanism 6 and is used to adjust the clamping surface angle of the clamping mechanism 6. The second adjustment mechanism 5 includes: a corner reduction gearbox, a second motor, a pedestal bearing, and a synchronous belt wheel mechanism. Since the pole-mounted switch has different assembly surfaces, when it is necessary to assemble or repair different assembly surfaces, the second motor of the second adjustment mechanism 5 drives the corner reduction gearbox to rotate an angle, so that the pole-mounted switch product clamped in the clamping mechanism rotates by a corresponding angle, further improving the function of the compatibility device.

[0038] Through the above implementation manner, pole-mounted switches of different models can all be clamped and rotated under the action of the above compatibility device, thereby improving the automation degree and production efficiency of the production process of the pole-mounted switch.

[0039] The present utility model also provides a second embodiment of a compatibility device applied to a pole-mounted switch. The difference between the second embodiment and the first embodiment is that the transmission component in the second embodiment is composed of a gear vertical transmission unit. Compared with synchronous belt transmission, the transmission efficiency of gear transmission is as high as 0.94 - 0.99; and it can provide a large and accurate transmission ratio in a smaller space. For scenarios where precise control of the clamping distance of the clamping mechanism is required, gear transmission is more suitable; on the other hand, gear transmission is applicable to different working environments and load conditions. Regarding the selection of gear transmission or synchronous belt transmission, it needs to be customized according to the actual needs of users.

[0040] Refer to Figure 6 , Figure 6Describe the kinematic diagram of the gear transmission mechanism. It can be seen from the figure that if it is currently necessary to reduce the size of the clamping space, the first motor 412 needs to be controlled to drive counterclockwise, and then the bidirectional lead screw is driven to move towards each other through the gear transmission component, so that the clamping mechanism 6 moves towards each other. Similarly, if it is currently necessary to increase the size of the clamping space, the first motor 412 needs to be controlled to drive clockwise, and then the bidirectional lead screw is driven to move away from each other through the gear transmission component, so that the clamping mechanism 6 moves away from each other.

[0041] The present invention also provides a third embodiment of a compatibility device applied to a pole-mounted switch. The third embodiment is improved on the basis of the above-mentioned first embodiment or the second embodiment. The improvement lies in that: the compatibility device further includes: a positioning mechanism (not shown in the figure). The positioning mechanism is arranged above the first adjustment mechanism and is used to position the position of the adjusted clamping mechanism 6. The positioning mechanism can be a baffle, a stop block, or other components with a positioning function. By adding the positioning mechanism, the clamping accuracy and stability of the compatibility device can be further improved.

[0042] The present invention also provides a fourth embodiment of a compatibility device applied to a pole-mounted switch. The fourth embodiment is improved on the basis of the above-mentioned third embodiment. The improvement lies in that: the compatibility device further includes: a buffer mechanism (not shown in the figure). The buffer mechanism is arranged at both ends of the first adjustment mechanism. The buffer mechanism can be an oil buffer, a spring buffer component, a rubber buffer component, etc.; as long as it can achieve a buffering effect, it is within the protection scope of the present invention.

[0043] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.

[0045] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered by the protection scope of the present invention.
