[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0047] At present, the transfer trolley equipped with the existing circuit breaker does not have the lifting or flipping function. Since the weight of the circuit breaker trolley is between 160kg and 320kg, when inspecting the trolley chassis and the components such as the switch buffer, 4-7 maintenance personnel are required to manually lift the circuit breaker trolley to the ground and turn it sideways for inspection. During this work process, it is easy to cause personal injury and the external insulation parts of the circuit breaker trolley are also easy to be damaged. This embodiment provides a circuit breaker trolley maintenance platform, which effectively solves the technical problem of inconvenient maintenance of the existing circuit breaker trolley.

[0048] See also Figure 1-Figure 8 The embodiment of the present application provides a circuit breaker trolley maintenance platform, including a working platform 1, a guide rail seat 2 and a width adjustment mechanism 3; there are two guide rail seats 2, and the two guide rail seats 2 are respectively arranged on both sides of the working platform 1; the width adjustment mechanism 3 is connected to at least one guide rail seat 2, and is used to adjust the distance between the two guide rail seats 2; each guide rail seat 2 is provided with a track 21 matching the roller 61 of the circuit breaker trolley 6; a locking mechanism 4 for fixing and locking the roller 61 is installed in the track 21; each guide rail seat 2 is installed with a telescopic rod 5; the bottom end of the telescopic rod 5 is movably connected to the corresponding guide rail seat 2, and the top end of the telescopic rod 5 is connected to the hoisting hole 62 of the circuit breaker trolley 6 through a fastener 51.

[0049] More specifically, one of the guide rail seats 2 may be connected to the width adjustment mechanism 3, and the other guide rail seat 2 may be fixed on the work platform 1. The width adjustment mechanism 3 may be used to drive the guide rail seat 2 to move toward or away from the other guide rail seat 2, thereby achieving the effect of adjusting the distance between the two guide rail seats 2. Alternatively, both guide rail seats 2 may be connected to the width adjustment mechanism 3, and the width adjustment mechanism 3 may be used to drive the two guide rail seats 2 to move toward or away from each other, thereby also achieving the effect of adjusting the distance between the two guide rail seats 2. Figure 5 The internal cavity of the track 21 is in a convex shape, and the roller 61 of the circuit breaker trolley 6 is installed in the track 21, which can well limit the roller 61 of the circuit breaker trolley 6 from being separated from the track 21, thereby ensuring that the circuit breaker trolley 6 can move normally on the working platform 1; the table top of the working platform 1 is concave, wherein the rear half of the table top is open.

[0050] In this embodiment, the distance between the two guide rail seats 2 is adjusted by the width adjustment mechanism 3, so that the track 21 on the working platform 1 matches the width of the circuit breaker trolley 6, so that the circuit breaker trolley 6 can be pulled onto the working platform 1, wherein the rollers 61 of the circuit breaker trolley 6 are located in the matching track 21, and the side walls of the circuit breaker trolley 6 are connected by the telescopic rod 5. The position of the circuit breaker trolley 6 can be fixed by the locking mechanism 4; when the circuit breaker trolley 6 needs to be turned over, the locking mechanism 4 can be released, and the circuit breaker trolley 6 can be continued to be moved so that part of the rollers 61 are out of the way. The breaker trolley 6 is separated from the track 21. Under the limiting effect of the telescopic rod 5, the center of gravity of the breaker trolley 6 moves backward, causing the breaker trolley 6 to flip 90 degrees. Then, the other rollers 61 located in the track 21 are locked and fixed by the locking mechanism 4, so as to fix the position of the breaker trolley 6, so as to facilitate the maintenance of the breaker trolley 6, and effectively solve the technical problem of the inconvenience of the maintenance of the existing breaker trolley 6. At the same time, the setting of the telescopic rod 5 can also effectively protect the breaker trolley 6, which is conducive to preventing the external insulating parts of the breaker trolley 6 from being damaged.

[0051] Further, in this embodiment, please refer to Figure 4 The width adjustment mechanism 3 includes an adjustment hand wheel 31 and a forward and reverse screw rod 32; the forward and reverse screw rod 32 is rotatably arranged on the working platform 1, and at least one end of the forward and reverse screw rod 32 is connected to the adjustment hand wheel 31; the two guide rail seats 2 are respectively threadedly sleeved on the two ends of the forward and reverse screw rod 32. By rotating the forward and reverse screw rod 32 by the adjustment hand wheel 31, the rotation of the forward and reverse screw rod 32 can drive the two guide rail seats 2 to move toward or away from each other, thereby adjusting the distance between the two guide rail seats 2, so that the track 21 on the working platform 1 matches the width of the circuit breaker trolley 6, so as to pull the circuit breaker trolley 6 onto the working platform 1.

[0052] More specifically, an adjusting hand wheel 31 may be installed at one end of the forward and reverse screw rod 32 , or at both ends of the forward and reverse screw rod 32 ; the forward and reverse screw rod 32 is rotatably installed on the working platform 1 through bearings.

[0053] Further, in this embodiment, please refer to Figure 4 , the two guide rail seats 2 are slidably mounted on the working platform 1 through the guide rods 33. Both ends of the guide rods 33 are fixedly mounted on the working platform 1, and the guide rods 33 are arranged in parallel with the forward and reverse screw rods 32. The guide rail seats 2 are slidably sleeved on the guide rods 33. The setting of the guide rods 33 can effectively limit the guide rail seats 2 with a longer length, which is conducive to ensuring the stability of the two guide rail seats 2 when they move toward or away from each other, and achieve the effect of adjusting the distance between the two guide rail seats 2.

[0054] Further, in this embodiment, please refer to Figure 4The number of guide rods 33 is at least two, and each guide rod 33 is evenly distributed on the guide rail seat 2. The provision of multiple guide rods 33 can further limit the guide rail seat 2 and ensure the left-right balance of the guide rail seat 2, which is conducive to guiding the two guide rail seats 2 to move in a straight line, thereby achieving the effect of adjusting the distance between the two guide rail seats 2.

[0055] Further, in this embodiment, please refer to Figure 5-Figure 8 The locking mechanism 4 is specifically a key; the key includes a knob 41, a base plate 42, a limit piece 43 and a stop rod 44; the outer side of the base plate 42 is connected to the knob 41, and the length of the knob 41 is greater than the outer diameter of the base plate 42; the inner side of the base plate 42 is connected to the stop rod 44, and the outer diameter of the stop rod 44 is not greater than the outer diameter of the base plate 42; the side wall of the stop rod 44 is provided with a limit piece 43; the track 21 is provided with a locking hole 22 for the base plate 42 and the limit piece 43 to pass through. When it is necessary to fix the roller 61 of the circuit breaker trolley 6, the base plate 42 and the limiter 43 are inserted into the track 21 through the locking hole 22, wherein the stopper 44 is located in the track 21 to limit the movement of the roller 61, and the knob 41 is located outside the track 21. Then, the knob 41 is turned to make the limiter 43 rotate a certain angle to be offset from the locking hole 22, so that the entire key cannot be pulled out of the locking hole 22, thereby achieving the function of fixing the key. The two stoppers 44 can block and limit the forward and backward movement of the roller 61, thereby fixing the position of the circuit breaker trolley 6, so as to perform maintenance operations on the circuit breaker trolley 6.

[0056] More specifically, an elastic gasket 45 may be provided on the blocking rod 44 so that when the staff pulls the key due to misoperation, the elastic gasket 45 can effectively protect the limiter 43; see Figure 6 The locking hole 22 includes a circular hole 221 corresponding to the base plate 42 and a strip hole 222 corresponding to the limiter 43. When there are two limiters 43, the two strip holes 222 are arranged on both sides of the circular hole 221 and communicate with the circular hole 221, so that the limiter 43 and the base plate 42 pass through the locking hole 22; the hoisting hole 62 on the circuit breaker trolley 6 can also adopt the shape of the locking hole 22, and then the fastener 51 at the top of the telescopic rod 5 can also adopt a key. Similarly, the telescopic rod 5 can be fixedly connected to the circuit breaker trolley 6 through the key and the locking hole 22.

[0057] Further, in this embodiment, please refer to Figure 6There are multiple locking holes 22; the multiple locking holes 22 are distributed along the length direction of the track 21. Each locking hole 22 is equipped with a corresponding key. When the position of the circuit breaker trolley 6 needs to be fixed, the key can be inserted into the locking holes 22 in front and behind the roller 61 of the circuit breaker trolley 6 to limit the movement of the roller 61 of the circuit breaker trolley 6 in the front and rear directions, thereby achieving the effect of locking the position of the circuit breaker trolley 6, so that the circuit breaker trolley 6 can be repaired on the working platform 1.

[0058] Further, in this embodiment, please refer to Figure 2 and Figure 3 The guide rail seat 2 is provided with an oblong hole 23; the bottom end of the telescopic rod 5 is movably installed in the oblong hole 23. The bottom end of the telescopic rod 5 can be installed in the oblong hole 23 of the guide rail seat 2 by a bolt. The arrangement of the oblong hole 23 enables the telescopic rod 5 to adapt to the size deviation of the circuit breaker trolley 6 of different lengths and models, and then adjust the fulcrum position of the telescopic rod 5 to form a necessary self-locking angle with the top end of the telescopic rod 5. Whether before or after flipping, the telescopic rod 5 can form an effective support effect on the circuit breaker trolley 6.

[0059] Further, in this embodiment, the telescopic rod 5 is specifically a hydraulic rod or an electric telescopic rod. No matter whether a hydraulic rod or an electric telescopic rod is used as the telescopic rod 5, the purpose of finely controlling the length of the telescopic rod 5 is achieved, so as to better support the circuit breaker trolley 6.

[0060] Further, in this embodiment, please refer to Figure 1 The working platform 1 is provided with a plurality of supporting feet 11; each supporting foot 11 is provided with a lifting wheel 12. The setting of the lifting wheel 12 can change the moving mode of the working platform 1, so that the staff can push the working platform 1 to move more easily, which is conducive to increasing the convenience of the operation.

[0061] Further, in this embodiment, please refer to Figure 1 Each lifting wheel 12 is adjustably connected to the corresponding supporting foot 11. By adjusting the common height of the supporting foot 11 and the lifting wheel 12, the height of the working platform 1 is adjusted so that the circuit breaker trolley 6 can be moved onto the working platform 1.

[0062] More specifically, the lifting wheel 12 can be threadedly connected to the support foot 11 through a threaded rod, and the lifting wheel 12 can be controlled to move away from or close to the support foot 11 by rotating the lifting wheel 12, thereby achieving the purpose of adjusting the height of the working platform 1.

[0063] The specific working process of this embodiment:

[0064] (1) The height of the working platform 1 can be adjusted by the lifting wheel 12. The working platform 1 is equipped with two guide rail seats 2 (the guide rail seats 2 are provided with tracks 21 matching the rollers 61) whose widths can be adjusted left and right by adjusting the hand wheel 31 to adapt to the circuit breaker trolleys 6 of different widths. The bottom end of the telescopic rod 5 moves left and right along with the guide rail seat 2, and the top end of the telescopic rod 5 is connected to the circuit breaker trolley 6 through the fastener 51 and the lifting hole 62; after the circuit breaker trolley 6 moves to the working platform 1, the locking mechanism 4 is used to lock and fix the two sides of the front wheels of the circuit breaker trolley 6, and the self-locking keys at the top ends of the hydraulic rods on both sides are inserted into the lifting holes 62 of the circuit breaker trolley 6, and the self-locking keys can be rotated to self-lock and locked with the locking nuts.

[0065] (2) When the circuit breaker trolley 6 needs to be turned over, please refer to Figure 2 First, release the locking mechanism 4 of the front wheel of the circuit breaker trolley 6, pull the handle of the circuit breaker trolley 6 forward, so that the front wheel below the circuit breaker trolley 6 is off the track 21, and then continue to pull the circuit breaker trolley 6 upward (in the direction of the arc tip). Due to the restraint of the telescopic rod 5 and the restraint of the rear wheel of the circuit breaker trolley 6 by the track 21, the circuit breaker trolley 6 will flip backward 90 degrees, so that the bottom of the circuit breaker trolley 66 is turned to the front for easy maintenance. After flipping 90 degrees, the rear wheel of the circuit breaker trolley 6 is locked and fixed by the locking mechanism 4 to prevent movement during maintenance;

[0066] (3) After the bottom inspection of the circuit breaker trolley 6 is completed, refer to Figure 3 First, release the locking mechanism 4 of the rear wheel of the circuit breaker trolley 6, then pull the handle of the circuit breaker trolley 6 backward and downward (in the direction of the arc tip), the rear wheel of the circuit breaker trolley 6 will slide backward, and the circuit breaker trolley 6 will flip 90 degrees. At this time, push the front wheel of the circuit breaker trolley 6 into the guide rail, and when the front wheel reaches the locking device, lock the front wheel through the locking mechanism 4, and then use the lifting wheel 12 to move the working platform 1 to the switch cabinet. After aligning the track 21 of the switch cabinet, release the locking mechanism 4, and then push the circuit breaker trolley 6 into the switch cabinet to complete the reinstallation.

[0067] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
