[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] As mentioned in the background technology, when the power system is shut down for maintenance or when some equipment is shut down, the existing trolley switch cabinet needs to use the trolley rocker to swing the trolley out or in to disconnect or connect the switch cabinet. The existing trolley rocker is usually a "Z" or "bow" shaped structure. One end of the rocker is plugged into the rocker socket of the trolley, and the other end is for the operator to hold and rotate, so that the rocker drives the trolley to swing in and out.

[0034] However, since only one end of the existing trolley rocker structure is connected to the switch cabinet and the force is unstable, it is difficult for the rocker to maintain a uniform speed during the rotation process. This can easily cause the contacts of the trolley switch to collide, causing safety hazards, and also requires a high level of physical strength from the operator.

[0035] Furthermore, since the trolley rocker is only plugged into the rocker socket without being fastened or limited, the trolley rocker is easily separated from the trolley during the rotation process.

[0036] In order to overcome the defects in the prior art, the present application provides a trolley rocker device and a switch cabinet. The trolley rocker device is equipped with a planetary gear train assembly so that the operating part and the connector are respectively connected to the input side and the output side of the planetary gear train assembly, and the smooth force transmission characteristic of the planetary gear train assembly is utilized to enable the trolley to be rocked in or out at a uniform and smooth speed.

[0037] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0038] Figures 1 to 4 The schematic diagram of each component in the trolley rocker device is shown. The specific structure of the trolley rocker device and other components in the switch cabinet is not limited to Figures 1 to 4 of examples.

[0039] On the one hand, referring to Figure 1 As shown, an embodiment of the present application provides a trolley rocker device for connecting to a trolley of a switch cabinet. The trolley rocker device includes an operating member 100, a connector 200 and a planetary gear train assembly 300. The operating member 100 is connected to the input side of the planetary gear train assembly 300, the connector 200 is connected to the output side of the planetary gear train assembly 300, the connector 200 is used to be plugged into the rocker socket of the trolley, and the planetary gear train assembly 300 is used to connect to the trolley.

[0040] The operating member 100 is configured to drive the planetary gear train assembly 300 to drive the connector 200 to rotate around the axis of the connector 200 under the action of an external force.

[0041] It should be noted that the planetary gear train assembly 300 has a planetary gear 331 system structure and correspondingly has the characteristics of the planetary gear 331 system structure. Its overall structure is simple and compact, and because the load acting on the output side is dispersed on a large number of gear teeth, it can withstand a large load, and the force transmission process is relatively smooth, so that the output side can rotate at a relatively stable speed without causing obvious sudden changes in speed.

[0042] Furthermore, by setting up a planetary gear train assembly 300, connecting the operating part 100 on its output side and connecting the connector 200 on its input side, the connector 200 is connected to the rocker socket of the trolley. When the operator applies external force to the operating part 100, the operating part 100 can drive the planetary gear set 330 to operate, and then drive the connector 200 to rotate, so as to realize the uniform speed of rocking in or out of the trolley, and the movement of the trolley is more stable and smooth.

[0043] And because it is necessary to ensure the stability of the relative position of the planetary gear train assembly 300 and the trolley during operation, the planetary gear train assembly 300 is also required to be connected to the trolley. Thus, while achieving stable operation of the planetary gear train assembly 300, a stable connection between the trolley rocker device and the trolley can be avoided, thereby avoiding detachment from the trolley during the process of rocking the trolley in or out.

[0044] Therefore, the trolley rocker device and switch cabinet provided in the present application, the trolley rocker device is provided with a planetary gear train assembly 300, an operating member 100 and a connector 200, so that the operating member 100 and the connector 200 are respectively connected to the input side and the output side of the planetary gear train assembly 300, and the planetary gear train assembly 300 is connected to the trolley of the switch cabinet, so that the operator can insert the connector 200 into the rocker socket of the trolley, apply external force to the operating member 100 so that the operating member 100 drives the planetary gear train assembly 300 to operate, and drives the connector 200 to rotate in the rocker socket, thereby realizing the rocking in and out of the trolley, because the planetary gear train assembly 300 has the characteristic of stable force transmission, during the driving process of the operating member 100, no matter where it is relative to the operator, it can stably transmit external force to the connector 200, so that the trolley can be rocked in or out at a uniform and stable speed.

[0045] Furthermore, the planetary gear train assembly 300 is connected to the trolley, and when the operator is rocking the trolley in or out, the trolley rocker device will not be detached from the trolley, so that the trolley can be rocked in or out smoothly and reliably.

[0046] Further, in some embodiments, referring to Figure 1 As shown, the trolley rocker device provided in this embodiment further includes an adsorption assembly, and the adsorption assembly is used to connect the planetary gear train assembly 300 to the trolley.

[0047] By connecting the planetary gear train assembly 300 to the trolley through the adsorption component, the planetary gear train assembly 300 can be stably connected to the trolley during the process of rocking the trolley in and out. When the trolley rocker device needs to be removed from the trolley, the adsorption component and the trolley can be cancelled and the trolley rocker device can be easily removed.

[0048] Among them, refer to Figure 1 and Figure 2 As shown, the planetary gear train assembly 300 includes a ring gear 310 , a sun gear 320 , and a planetary gear set 330 . The planetary gear set 330 is meshed with the ring gear 310 . The sun gear 320 is coaxially arranged with the ring gear 310 , and the sun gear 320 is meshed with the planetary gear set 330 .

[0049] One of the planetary gear set 330 and the ring gear 310 is connected to the operating member 100 , the other of the planetary gear set 330 and the ring gear 310 is used to be connected to the trolley through an adsorption assembly, and the connector 200 is connected to the sun gear 320 .

[0050] It can be understood that since the position of the rocker socket on the trolley is fixed, the relative position between the output end of the planetary gear train assembly 300 and the rocker socket needs to be stable to ensure smooth transmission of the connector 200. Therefore, in the planetary gear train assembly 300, the connector 200 is coaxially connected to the sun gear 320 located at the center of the planetary gear train assembly 300.

[0051] Therefore, it is only necessary to ensure that the relative position of one of the planetary gear set 330 and the ring gear 310 with the sun gear 320 is fixed, and the sun gear 320 is driven to rotate at the fixed position. Figure 1 As shown in the figure, the operating member 100 is set on the planetary gear set 330 to drive the planetary gear set 330 to rotate around the sun gear 320, so that the ring gear 310 is fixedly connected to the trolley; the operating member 100 can also be set on the ring gear 310 to drive the ring gear 310 to rotate around the sun gear 320, so that the planetary gear set 330 is connected to the trolley, so that the axis of the planetary gear set 330 is fixed, and each planetary gear 331 rotates around its own axis.

[0052] Furthermore, in this embodiment, there is no restriction on the relationship between the number of teeth, the module relationship, and the transmission ratio between the planetary gear set 330 and the sun gear 320, and between the planetary gear set 330 and the ring gear 310. For example, according to specific needs, the number of teeth of the planetary gear 331 of the planetary gear set 330 can be set to be greater than that of the sun gear 320, so that the operator can drive the trolley to swing in and out relatively quickly with a large torque and a high speed. The number of teeth of the planetary gear 331 of the planetary gear set 330 can also be set to be less than that of the sun gear 320, so that the operator can drive the trolley to swing in and out relatively slowly with a small torque and a low speed, both of which can ensure that the trolley moves at a uniform speed.

[0053] In a specific implementation, the planetary gear set 330 includes a planet carrier 332 and at least two planetary gears 331 . The planetary gears 331 are evenly distributed in the ring gear 310 and meshed with the ring gear 310 and the sun gear 320 . The planet carrier 332 is connected to the axis of each planetary gear 331 .

[0054] The operating member 100 is fixedly disposed on the planet carrier 332 .

[0055] Providing two or more planetary gears 331 can ensure that the planetary gear train assembly 300 transmits force smoothly.

[0056] In this embodiment, three planetary gears 331 are provided. The planets are composed of three connecting rods connected at the same point. The angles between two adjacent connecting rods are consistent, and the connection point is located on the axis of the sun gear 320, so that the planetary gear train assembly 300 runs more smoothly.

[0057] In other embodiments, the planet carrier 332 may also be formed by three connecting rods connected end to end, and the present application does not limit this. It should be noted that when the number of planetary gears 331 increases, a corresponding number of connecting rods need to be provided to connect them.

[0058] Furthermore, when the operating member 100 is connected to the center of the planetary frame 332, the operating member 100 has a handle member 110, a first connecting section 120 and a second connecting section 130 connected in sequence, the handle member 110 and the second connecting section 130 are both perpendicular to the first connecting section 120, and the handle member 110 and the second connecting section 130 are in opposite directions.

[0059] The second connecting section 130 is connected to the planet carrier 332 , and an extending direction of the second connecting section 130 coincides with an axis of the connector 200 .

[0060] It can be understood that setting the operating member 100 at the center of the planetary frame 332 can reduce the operating range of the operator accordingly, and the operating member 100 formed by the handle portion 110, the first connecting section 120 and the second connecting section 130 makes it easier for the operator to apply torque to the planetary gear train assembly 300 and drive it to rotate.

[0061] A sleeve is provided on the handle 110 , and the sleeve is rotatably connected to the handle 110 , so that an operator can hold and operate the handle 110 .

[0062] When the operating member 100 is connected to the side of the planet carrier 332 and does not coincide with the axis of the plug-in member 200, the operating member 100 can be formed by only the handle member 110, and when the operator applies external force, the distance between the mounting point of the handle member 110 on the planet carrier 332 and the axis of the plug-in member 200 is used to equivalently form a torque, making the structure of the operating member 100 simpler. Specifically, the handle member 110 can be coaxially connected to the axis of any planetary gear 331.

[0063] In addition, if Figures 1 to 3 As shown, in order to prevent the connector 200 from being worn and affecting the transmission between the connector and the trolley, the connector 200 and the sun gear 320 are detachably connected in this embodiment, so that the connector 200 can be replaced in time.

[0064] The two ends of the connector 200 are respectively a first plug end 210 and a second plug end 220. The first plug end 210 is a socket, which matches with the plug block on the sun gear 320, and the second plug end 220 is a plug, which matches with the rocker socket on the trolley.

[0065] Furthermore, in order to improve the interchangeability and versatility of the trolley rocker device and the connector 200, so that it can be applicable to switch cabinet trolleys of various voltage levels, different models and different specifications, multiple connectors 200 can be provided, and each connector 200 has different size specifications.

[0066] Specifically, the lengths of the connectors 200 in the extending direction may be different, or the sizes of the second connector ends 220 of the connectors 200 may be different, without adjusting the size specifications of the first connector ends 210 connected to the planetary gear train assembly 300 .

[0067] In some other embodiments, the trolley rocker device further includes at least one limit member (not shown), which at least partially covers at least one side end surface of at least one of the ring gear 310 , the sun gear 320 and the planetary gear set 330 .

[0068] It can be understood that a limit member cover is provided on at least one side end face of the ring gear 310, the sun gear 320 and the planetary gear set 330 so that the limit member abuts against the end faces of the ring gear 310, the sun gear 320 and the planetary gear set 330 to prevent any one of the ring gear 310, the sun gear 320 and the planetary gear set 330 from being disconnected from the other two and causing the trolley rocker device to fail.

[0069] The limiting member may be a baffle disposed on its end surface, or a shell covering the entire periphery of the planetary gear train assembly 300 , and corresponding mounting holes 311 of the operating member 100 and the connector 200 need to be reserved to prevent interference with the operation.

[0070] Reference Figure 1 and Figure 4 As shown, the adsorption assembly includes at least three adsorption members 400, which are used to adsorb the surface of the trolley. At least three mounting holes 311 are sequentially arranged on the end surface of the gear ring 310 facing the plug-in member 200, and each adsorption member 400 is detachably connected to the mounting hole 311.

[0071] Since the operating member 100 is disposed on the planet carrier 332 , the adsorption member 400 can be disposed on the ring gear 310 . Three or more adsorption members 400 can ensure that the planetary gear train assembly 300 and the ring gear 310 are reliably connected.

[0072] In a specific implementation, three or more mounting holes 311 may be sequentially and spaced apart on the gear ring 310, for example Figure 4 As shown in the figure, six evenly distributed mounting holes 311 are arranged on the gear ring 310, so that when the adsorption member 400 is adsorbed to the trolley, the adsorption member 400 can be set in any three of the six mounting holes 311 to avoid the adsorption member 400 from blocking the observation window and the five-anti-lock accessories on the trolley.

[0073] The adsorption member 400 may be a suction cup, or may be a magnet, an adhesive block or other component with adsorption capability, and the present application does not impose any limitation on this.

[0074] On the other hand, the present application provides a switch cabinet, comprising a switch cabinet body and any one of the above-mentioned trolley rocker devices, the switch cabinet having a trolley, and the trolley rocker device being connected to the trolley.

[0075] Among them, the trolley rocker device has been explained in the above embodiments and will not be repeated here.

[0076] Therefore, the trolley rocker device and switch cabinet provided in the present application, the trolley rocker device is provided with a planetary gear train assembly 300, an operating member 100 and a connector 200, so that the operating member 100 and the connector 200 are respectively connected to the input side and the output side of the planetary gear train assembly 300, and the planetary gear train assembly 300 is connected to the trolley of the switch cabinet, so that the operator can insert the connector 200 into the rocker socket of the trolley, apply external force to the operating member 100 so that the operating member 100 drives the planetary gear train assembly 300 to operate, and drives the connector 200 to rotate in the rocker socket, thereby realizing the rocking in and out of the trolley, because the planetary gear train assembly 300 has the characteristic of stable force transmission, during the driving process of the operating member 100, no matter where it is relative to the operator, it can stably transmit external force to the connector 200, so that the trolley can be rocked in or out at a uniform and stable speed.

[0077] In order to ensure that the planetary gear train assembly 300 can stably transmit power, the planetary gear train assembly 300 is connected to the trolley, so that when the operator shakes the trolley in or out, the trolley rocker device will not detach from the trolley, making the trolley shaking in and out smooth and reliable.
