[0002] The medium-mounted cabinet handcart is an important component in a medium-mounted high-voltage switch cabinet, which is convenient for equipment maintenance: it can be withdrawn from the switch cabinet, facilitating the inspection, repair and replacement of equipment such as circuit breakers without power outage affecting the operation of the entire switch cabinet. There are strict operation procedures and interlock devices for the handcart to switch between different positions, namely the working position, the test position and the maintenance position, which can effectively prevent misoperation and ensure the safety of operators. Electrical components such as circuit breakers are installed on the handcart, and the on-off and control of the circuit are realized by contacting the fixed components in the switch cabinet.

[0003] In the process of implementing the present utility model, the inventor found that the prior art has the following problems: 1. The medium-mounted cabinet handcart is usually used in a high-voltage power system. It requires manual use of a movable rocker to insert it into the docking groove and manually drive the rocker to rotate, resulting in the arm always maintaining a single action of rocking, increasing the labor intensity of the work, being time-consuming and laborious. When the rocker needs to be shaken to the circuit breaker mechanism, a spring locking sound will be heard to achieve fixation. Due to the uneven shaking speed or excessive force of the user, the shaker may not be able to shake, and due to the internal parts hitting the eyebrow-shaped part and the spring of the eyebrow-shaped baffle being stuck, the user may make a wrong judgment and think that the correct position has been reached; 2. The internal cost of the medium-mounted cabinet handcart is relatively high. Since the rocker is used in a power device, it is not convenient to disassemble the internal automatic rocker assembly when it is aged and damaged later. The traditional hand rocker is relatively laborious to shake. Content of the Utility Model

[0004] The purpose of the present utility model is to provide an automatic rocking-in and rocking-out device for a 10KV medium-mounted cabinet handcart to solve the problem in the above-mentioned background art that manual shaking of the handle may cause the internal parts of the equipment to be stuck due to uneven speed or excessive force of the user, resulting in a wrong operation when thinking that the correct position has been reached. To achieve the above purpose, the present utility model provides the following technical solution: An automatic rocking-in and rocking-out device for a 10KV medium-mounted cabinet handcart, including an equipment body, a second docking groove is provided inside the equipment body, a fixed groove is installed in front of the equipment body through screws, and a slide rail is provided above the fixed groove;

SPECIFIC EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a 10KV medium-mounted cabinet handcart automatic rocking-in and rocking-out device, including an equipment body 1, a second docking groove 3 is provided inside the equipment body 1, a fixing groove 4 is installed in front of the equipment body 1 by screws, and a slide rail 2 is provided above the fixing groove 4;

[0022] A plug board 201 is welded at the rear of the slide rail 2. A moving plate 210 is fitted inside the slide rail 2. A first slider 204 is welded on one side of the moving plate 210. A push plate 205 is welded above the first slider 204. A cylinder 206 is inserted on one side of the push plate 205. One side of the cylinder 206 is connected to a controller 207 through a cable. An arc-shaped groove 203 is welded on the other side of the moving plate 210. A second slider 202 is fitted inside the arc-shaped groove 203. A hand crank 208 is rotatably connected to the rear of the second slider 202. The other side of the hand crank 208 is rotatably connected to a first docking groove 209.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the first slider 204 and the push plate 205 are integrally connected. The outer wall structure size of the first slider 204 is consistent with the internal structure size of the slide rail 2. And the push plate 205 forms a sliding structure through the cylinder 206. The cylinder 206 drives the first slider 204 to move by the push plate 205. The first slider 204 moves inside the slide rail 2, which can adjust the rotation speed of the adjustable hand crank 208 according to the cylinder 206 connected to the controller 207, avoiding too fast rotation speed of the hand crank 208.

[0024] In this embodiment, as Figure 3 shown, the first docking groove 209 forms a rotating structure through the hand crank 208. The middle cabinet handcart has a more uniform rocking speed compared with the existing manual rocker. The hand crank 208 is provided with an adjusting component for rocking the first docking groove 209 to adjust the rotation force and speed, avoiding uneven rocking.

[0025] In this embodiment, as Figure 3 shown, the second slider 202 forms a sliding structure through the arc-shaped groove 203. And the internal structure size of the arc-shaped groove 203 is consistent with the external structure size of the second slider 202. The moving plate 210 reciprocates the arc-shaped groove 203. The arc-shaped groove 203 can drive the hand crank 208 to rotate by the second slider 202 inside, converting linear motion into rotational motion, realizing the conversion of motion forms, making the rotational motion of the hand crank 208 more stable, reducing impact and vibration, and helping to improve the stability and reliability of the whole system. Through the shape, length of the arc-shaped groove 203 and the motion law of the second slider 202, it is relatively easy to control the rocking speed, amplitude and period of the hand crank 208.

[0026] In this embodiment, as Figure 1 and Figure 3 shown, the external structure size of the first docking groove 209 is consistent with the internal structure size of the second docking groove 3. The sizes of the first docking groove 209 and the second docking groove 3 fit together, which can avoid loosening during rotation and facilitate stable rotation.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a single-threaded screw rod 401 is threadedly connected to the inner wall of the fixed groove 4. A rotating handle 402 and a fixing plate 403 are respectively welded on both sides of the single-threaded screw rod 401. An anti-slip pad 404 is adhesively bonded to one side of the fixing plate 403. Moreover, the fixing plate 403 forms a rotating structure through the single-threaded screw rod 401. And a plurality of rectangular anti-slip pads 404 are horizontally attached to the outer side of one side of the fixing plate 403. The external structure size of the single-threaded screw rod 401 is consistent with the size of the circular hole provided on one side of the fixed groove 4; the rotating handle 402 drives the fixing plate 403 connected to the single-threaded screw rod 401 to rotate, so that the fixing plate 403 fixes the plug plate 201. The simple fixing and installation method can facilitate installation and disassembly, adapt to the use of multiple sets of opposite devices, and at the same time facilitate the maintenance of the equipment in the later stage.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the plug plate 201 is an inverted "L"-shaped plate, and the plug plate 201 is snap-fitted and fixed to the fixing plate 403 through the fixed groove 4; the plug plate 201 can be inserted into the plug plate 201 and fixed through the fixing plate 403, which can prevent the loosening of the butt-jointed first docking groove 209, and the fixed docking can avoid the risk of the manual rotating rocker slipping.

[0029] The usage method and advantages of the present utility model: For the 10KV medium-mounted cabinet handcart automatic advancing and retreating device, during use, the working process is as follows:

[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the bottom end of the plug board 201 is vertically inserted from the rectangular hole above the fixed slot 4, so that one side of the plug board 201 fits against the inner wall of the fixed slot 4. The single-threaded screw rod 401 is rotated clockwise by the rotating handle 402, so that the anti-slip pad 404 on one side of the fixed plate 403 abuts against the plug board 201. The inner wall hole groove of the fixed slot 4 and the single-threaded screw rod 401 are threadedly connected, so that the plug board 201 can be fixed when the fixed plate 403 is pushed in. Since the height of the first docking groove 209 is consistent with that of the second docking groove 3, when the rotating component on the fixed plug board 201 is fixed, the first docking groove 209 and the second docking groove 3 also fit and are fixed, avoiding loosening during later rotation. The controller 207 (model: KZQ) can accurately control the extension and retraction actions of the cylinder 206, as well as the movement speed, formation, and position. The cylinder 206 horizontally drives the push plate 205, the first slider 204, and the arc groove 203 to move to one side. Since the arc groove 203 can limit the movement track of the second slider 202 inside, when the arc groove 203 reciprocates through the moving plate 210, it drives the rocking handle 208 to rotate, realizing that the rocking handle 208 drives the first docking groove 209 to rotate and twist.
