Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, and in particular relates to a switch cabinet with a movable switch cabinet bracket device. Background Technology

[0002] A switchgear is an electrical device whose main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. Due to its large size and weight, switchgear needs to be transported and moved using a bracket.

[0003] Chinese utility model patent document CN218887852U describes a switch cabinet with a movable switch cabinet bracket device. This design uses an electric push rod of the top support assembly to push the connecting frame, causing the feet to contact the ground and lift the bracket, thus slightly raising the casters off the ground. Simultaneously, when the feet are pressed firmly against the ground, suction cups on their bottoms can firmly adhere to the surface, providing additional stability to the switch cabinet. However, this design has revealed some significant drawbacks in practical applications.

[0004] First, the top support assembly is located between the four casters and below the bracket, resulting in a relatively low chassis in the middle of the bracket. When the switchgear encounters thresholds or obstacles of a certain height during movement, the top support assembly in the middle of the bracket is prone to collision with the obstacles, potentially causing equipment damage or hindering movement. Furthermore, the insufficient chassis height due to the top support assembly design may prevent it from effectively overcoming obstacles, limiting its usability and convenience.

[0005] Secondly, while suction cups provide good adhesion on flat and smooth surfaces, their effectiveness is significantly reduced on rougher surfaces. This can lead to instability of the switch cabinet during placement, making it prone to sliding or tilting, thus increasing safety hazards.

[0006] Therefore, it is essential to invent a switch cabinet with a movable switch cabinet bracket device. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a switch cabinet with a movable switch cabinet bracket device, including a retractable bracket, a protective plate, a loading and unloading plate, a switch cabinet and a push rod. Three protective plates are fixedly installed on the top of the retractable bracket, and the loading and unloading plate is hinged. The switch cabinet is located inside the protective plate and the loading and unloading plate and is placed on the retractable bracket. The push rod is fixedly installed on the retractable bracket.

[0008] The retractable support includes a base, retractable slots, anti-slip pads, a two-way lead screw, a retractable motor, a pulley, a belt, ball nuts, a connector, a retractable upright arm, a carrier plate, and casters. Three protective plates and a push rod are fixedly installed on the upper surface of the base, and the loading / unloading plate is hinged thereon. The switch cabinet is placed on top of the base. The retractable slots are symmetrically mirrored on both sides of the lower part of the switch cabinet, and the anti-slip pads are placed between the two retractable slots, fixedly installed on the lower surface of the base. The two-way lead screws are rotatably mounted inside the two retractable slots on the base. A lead screw, one end of which of the two bidirectional lead screws rotates through the base and is fixed to the output end of the receiver / discharge motor that is fixedly mounted externally; a pulley is fixedly mounted in the middle of the two bidirectional lead screws, and belts are mounted on the pulleys of the two bidirectional lead screws; two ball nuts are mounted on a single bidirectional lead screw; connectors are mounted on both the ball nuts and the carrier plate, and the take-up / discharge arm is connected to the connectors on the ball nuts and the carrier plate respectively; four casters are fixedly mounted on the carrier plate, and the carrier plate is slidably mounted in the take-up / discharge groove.

[0009] Preferably, a set of guide rollers is rotatably mounted on the loading and unloading plate, the loading and unloading plate is located on one side above the base, the base is a rectangular structure, and one side surface of the base is fixedly connected to the base.

[0010] Preferably, the bidirectional lead screw is provided with two sections of threads with different directions of rotation, namely one section is a left-handed helix and the other section is a right-handed helix. The ball nuts are respectively installed on the two sections of the helix, and the ball nuts are slidably connected to the inner wall of the ball nut. The ball nuts are located on both sides of the pulley.

[0011] Preferably, the pulley is located directly above the carrier plate, and the base has a through groove that allows the belt mounted on the pulley to move. This through groove communicates with the two take-up and release grooves respectively.

[0012] Preferably, the carrier plate has a rectangular structure, and the four lower corners of the carrier plate are respectively fixedly installed with the casters; the carrier plate and the casters can be completely stored in the receiving slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention abandons the traditional method of relying on an electric push rod to drive the suction cup to adhere to the ground, and instead ingeniously adopts a retractable mechanism with a threaded drive and a linkage structure. This innovative design not only ensures smooth movement of the device, but also provides excellent stability without sacrificing the overall chassis height. Specifically, when the device is in motion, the two sets (four in a group) of universal wheels on the retractable support are in close contact with the ground, ensuring that the device can move flexibly on the ground. However, when stabilization is required, the retractable support cleverly uses a threaded drive mechanism and two linkage-type retractable arms to retract the eight universal wheels, removing them from contact with the ground. At this time, the anti-slip pad under the base will directly contact the ground, thus providing stable support for the device and significantly enhancing its stability. Attached Figure Description

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a switch cabinet with a movable switch cabinet bracket device, including a retractable bracket 1, a protective plate 2, a loading and unloading plate 3, a switch cabinet 4, and a push rod 5. Three protective plates 2 are fixedly installed on the top of the retractable bracket 1, and the loading and unloading plate 3 is hingedly installed. The switch cabinet 4 is located inside the protective plates 2 and the loading and unloading plate 3 and is placed on the retractable bracket 1. The push rod 5 is fixedly installed on the retractable bracket 1.

[0024] The retractable support 1 includes a base 11, retractable slots 12, anti-slip pads 13, a bidirectional lead screw 14, a retractable motor 15, a pulley 16, a belt 17, a ball nut 18, a connector 19, a retractable arm 10, a carrier plate 111, and casters 112. Three protective plates 2 and push rods 5 are fixedly installed on the upper surface of the base 11, and the loading / unloading plate 3 is hinged thereon. The switch cabinet 4 is placed on top of the base 11. The retractable slots 12 are mirror-symmetrically opened on both sides of the lower part of the switch cabinet 4, and the anti-slip pads 13 are arranged between the two retractable slots 12. The anti-slip pads 13 are fixedly installed on the lower surface of the base 11. The bidirectional lead screw 14 is rotatably installed inside the two retractable slots 12 opened on the base 11. A lead screw 14, one end of which is a bidirectional lead screw 14, rotates through the base 11 and is fixed to the output end of the externally mounted retractor 15; a pulley 16 is fixedly mounted in the middle of the bidirectional lead screw 14, and a belt 17 is mounted on the pulley 16 on both bidirectional lead screws 14; two ball nuts 18 are mounted on each of the single bidirectional lead screw 14; connectors 19 are mounted on both the ball nuts 18 and the carrier plate 111, and the retracting arm 10 is connected to the ball nuts 18 and the connectors 19 on the carrier plate 111 respectively; four casters 112 are fixedly mounted on the carrier plate 111, and the carrier plate 111 is slidably mounted in the retracting groove 12. The retractable support 1 adopts a retracting mechanism with a threaded transmission and linkage structure. This design not only ensures the smoothness of the device during movement, but also provides excellent stability without sacrificing the overall chassis height.

[0025] Example 1:

[0026] Specifically, a set of guide rollers is rotatably mounted on the loading and unloading plate 3 to facilitate loading and unloading operations. The loading and unloading plate 3 is located on one side above the base 11. The base 11 has a rectangular structure, and one side surface of the base 11 is fixedly connected to the base 11. The inclination of the loading and unloading plate 3 depends on the height of the base 11. The higher the base 11 is, the greater the inclination of the loading and unloading plate 3, and vice versa. When the caster wheel 112 is retracted, the inclination of the loading and unloading plate 3 reaches its minimum.

[0027] Specifically, the bidirectional lead screw 14 is provided with two sections of threads with different directions of rotation, namely one section is a left-handed helix and the other section is a right-handed helix. The ball nuts 18 are respectively installed on the two sections of threads. The ball nuts 18 are slidably connected to the inner wall of the pulley 16. The ball nuts 18 are located on both sides of the pulley 16.

[0028] Specifically, the pulley 16 is located directly above the carrier plate 111. To ensure smooth operation of the pulley 16 and the belt 17, a specially designed through slot is provided inside the base 11. This through slot not only allows the belt 17 mounted on the pulley 16 to move freely, but it also cleverly connects to the two take-up and release slots 12. This design ensures that the belt 17 can smoothly pass through the base 11, connecting the two bidirectional lead screws 14 located in different take-up and release slots 12. When the take-up and release motor 15 drives one of the bidirectional lead screws 14 to rotate, the other lead screw will also rotate synchronously through the transmission of the belt 17. This design allows the two ball nuts 18 to move simultaneously and evenly along the lead screws, thereby ensuring that the carrier plate 111 can rise or fall smoothly.

[0029] Specifically, the carrier plate 111 is designed as a rectangular structure to support the weight of the switch cabinet 4. To ensure that the device can flexibly switch between moving and stationary states, casters 112 are fixedly installed at the four lower corners of the carrier plate 111. The carrier plate 111 and the casters 112 can be completely stored in the storage slot 12. When the device needs to be moved, the carrier plate 111 and the casters 112 below it will descend below the base 11, so that the casters 112 are in contact with the ground, making it convenient for the user to push the entire device to move using the push rod 5. When the device needs to be stabilized, the carrier plate 111 and the casters 112 below it will be completely stored in the storage slot 12 of the base 11. This design not only ensures the stability of the device in a stationary state, but also makes the entire device more neat and aesthetically pleasing.

[0030] Example 2:

[0031] Working principle description:

[0032] The switch cabinet with a movable switch cabinet bracket device provided by this utility model has its core working principle in the design of its retractable bracket 1. When the switch cabinet 4 needs to be moved, the carrier plate 111 and the casters 112 can be easily raised and lowered by the drive of the retractable motor 15, thereby flexibly switching between moving and stationary states.

[0033] The specific work process is as follows:

[0034] stationary state:

[0035] In the initial state, the carrier plate 111 and the casters 112 below it are completely stored in the storage slot 12 of the base 11. At this time, the anti-slip pad 13 under the base 11 is in contact with the ground, providing stable support for the entire device.

[0036] In this state, after the loading and unloading plate 3 is opened, it can maintain a small tilt angle to ensure the ease of loading and unloading the switch cabinet 4. The switch cabinet 4 is located inside the guard plate 2 and the loading and unloading plate 3, and is placed on the base 11 of the retractable support 1. The base 11 bears its weight to ensure stability.

[0037] Movement status:

[0038] When the switch cabinet needs to be moved, the receiver / discharger 15 is started, and the motor output drives one of the bidirectional lead screws 14 to rotate. Since the two bidirectional lead screws 14 are connected by a belt 17 and a pulley 16, when one lead screw rotates, the other lead screw will also rotate synchronously.

[0039] Two threads with different directions of rotation on the bidirectional lead screw 14 drive two ball nuts 18 to move in opposite directions along the lead screw. The movement of the ball nuts 18 pushes the carrier plate 111 downward along the take-up and take-down groove 12 through the connector 19 and the take-up and take-down arm 10.

[0040] As the carrier plate 111 descends, the casters 112 beneath it gradually come into contact with the ground and eventually detach completely from the take-up / retractor slot 12, allowing the entire device to be easily moved via the push rod 5. At this point, the anti-slip pad 13 is no longer on the ground and does not provide support.

[0041] Return to a static state:

[0042] Once the device reaches the designated position, the receiver / discharge motor 15 is restarted, but in the opposite direction, causing the bidirectional lead screw 14 to rotate in the opposite direction.

[0043] The ball nut 18 moves upward along the lead screw, and pushes the carrier plate 111 and the caster wheel 112 upward through the retraction arm 10, and finally returns completely to the retraction slot 12.

[0044] At this point, the anti-slip pad 13 re-establishes contact with the ground, providing stable support for the device.

[0045] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
