This makes the device occupy less space while ensuring the overall structure of the device is simple, and increases the convenience of storage.

[0036] In one embodiment, see Figure 1 and Figure 4 A disassembly assembly 5 is provided between the bottom end of the supporting column 21 and the base 1. The disassembly assembly 5 includes a first insertion part 51 and a second insertion part 52. The first insertion part 51 is located on the bottom end of the supporting column 21, and the second insertion part 52 is located on the top surface of the base 1. The first insertion part 51 and the second insertion part 52 are interlocked. Specifically, the disassembly assembly 5 refers to a structure or component that allows two parts to be disassembled and connected. The disassembly assembly 5 can achieve disassembly and connection through methods such as insertion, snap-fit, or fastener 54 connection. The first insertion part 51 and the second insertion part 52 both refer to components or structures that can be interlocked with other components. For example, the first insertion part 51 can be an insertion post 511, in which case the second insertion part 52 is an insertion hole 521 or an insertion slot. In this embodiment, the bottom end of the support column 21 and the base 1 are detached and connected by the mutual insertion of the first insertion part 51 and the second insertion part 52, making the connection between the support column 21 and the base 1 more convenient and the structure of the whole device simpler.

[0037] In one embodiment, see Figure 4The first insertion part 51 includes an insertion post 511 disposed at the bottom end of the supporting column 21, and the second insertion part 52 includes an insertion hole 521 disposed on the base 1 and engaging with the insertion post 511. The insertion hole 521 is adapted to the shape of the insertion post 511. Specifically, the insertion post 511 refers to a component with a certain height, and the cross-sectional shape of the insertion post 511 can be circular, rectangular, or polygonal. The cross-section refers to the section cut by a plane perpendicular to the height direction of the insertion post 511. The insertion post 511 can be an integral structure with the supporting column 21, or it can be a separate component, installed at the bottom end of the supporting column 21 by means of snap-fit, welding, or fastener 54 connection. The insertion hole 521 refers to a hole structure with a certain depth, and the shape of the horizontal base surface of the insertion hole 521 matches the shape of the insertion post 511. In this embodiment, the cooperation between the plug-in post 511 and the plug-in hole 521 makes it easier to disassemble and connect the bottom end of the support column 21 to the base 1, and also makes the overall structure of the column assembly 2 simpler.

[0038] In one embodiment, see Figure 4 The disassembly assembly 5 also includes a connecting flange 53 and multiple fasteners 54. The connecting flange 53 is located at the bottom end of the support column 21 and is used to abut against the top surface of the base 1 when the first insertion part 51 and the second insertion part 52 are inserted into each other. The multiple fasteners 54 are used to connect the connecting flange 53 to the base 1. Specifically, the connecting flange 53 refers to a plate-like structure with a certain area. The connecting flange 53 is usually disc-shaped and surrounds the support column 21. The connecting flange 53 can be installed on the support column 21 by snap-fit, welding, or fastening. The fasteners 54 are components that thread the two parts together. The fasteners 54 can be screws, hand-tightened bolts, or bolts. Disassembly of the connecting flange 53 and the base 1 is more convenient, and hand-tightened bolts are preferred for the fasteners 54. In this embodiment, by providing a connecting flange 53 at the bottom end of the support column 21, and by having the connecting flange 53 abut against the top surface of the base 1 when the first insertion part 51 and the second insertion part 52 are inserted into each other, and by using multiple fasteners 54 to connect the connecting flange 53 to the base 1, the contact surface between the support column 21 and the base 1 is increased, which makes the installation of the support column 21 on the base 1 more secure and improves the overall stability of the device.

[0039] In an optional embodiment, please refer to Figure 4 A reinforcing rib can also be provided between the connecting flange 53 and the supporting column 21 to make the connection between the connecting flange 53 and the supporting column 21 more secure. At the same time, multiple fasteners 54 can be evenly arranged around the axis of the connecting flange 53 to make the stress on the connecting flange 53 more balanced.

[0040] In one embodiment, see Figure 1 and Figure 3 The sliding assembly 22 is provided with a locking groove 221, and at least a portion of the crossbeam portion 3 is accommodated within the locking groove 221. A locking component 222 is also movably disposed on the sliding assembly 22. The locking component 222 abuts against the crossbeam portion 3 when it is locked within the locking groove 221, thereby fixing the crossbeam portion 3 within the locking groove 221. Specifically, the locking groove 221 refers to a groove structure with a certain depth, generally arranged horizontally, and open at both ends. The locking component 222 refers to a component with a certain volume, and can be rod-shaped, block-shaped, or plate-shaped. The locking component 222 can be movably connected to the sliding assembly 22 through threaded connection or sliding connection, and the locking component 222 can fix the crossbeam portion 3 through snap-fit, abutment, or insertion. In this embodiment, by providing a locking groove 221 with both ends open on the sliding assembly 22, at least a portion of the crossbeam portion 3, such as the middle region, can be locked into the locking groove 221. The two ends of the crossbeam portion 3 can extend out of the locking groove 221 from their respective open ends. Simultaneously, a locking component 222 is movably provided on the sliding assembly 22. When the crossbeam portion 3 is installed into the locking groove 221, it abuts against the side of the crossbeam portion 3 and uses friction to fix the crossbeam portion 3 in the locking groove 221. Furthermore, when the crossbeam portion 3 needs to be removed from the locking groove 221, it disengages from the crossbeam portion 3, making the disassembly and installation of the crossbeam portion 3 more convenient and quick.

[0041] In an optional embodiment, please refer to Figure 3 The locking component 222 includes a locking screw. The first end of the locking screw is located inside the mounting groove 221, and the second end is located outside the mounting groove 221. The locking screw is threadedly connected to the sliding component 22. Rotating the locking screw allows it to move along its own axis, enabling the first end of the locking screw to approach or move away from the crossbeam 3. When approaching the crossbeam 3, it abuts against the side of the crossbeam 3, making the movement of the locking component 222 more convenient. Furthermore, a rotating handle can be provided at the second end of the locking screw, making its rotation even more convenient and quick.

[0042] In one embodiment, see Figure 3The drive structure 23 includes a rack 231, a gear 232, and a lifting handle 233. The rack 231 is mounted on the support column 21 and is positioned along the height of the support column 21. The gear 232 is rotatably mounted on the sliding assembly 22 and meshes with the rack 231. The lifting handle 233 is coaxially mounted with the gear 232 and is used to drive the gear 232 to rotate. Specifically, the rack 231 refers to a component with a certain length, and it also has meshing teeth arranged along the length of the rack 231. The gear 232 refers to a disc-shaped structure with a certain diameter, and it also has meshing teeth arranged around the axis of the gear 232 on its outer circumference. The lifting handle 233 refers to a component or assembly that allows the operator to rotate other objects. In this embodiment, a rack 231 is arranged along the height direction of the support column 21, and a gear 232 that meshes with the rack 231 is rotatably arranged on the sliding assembly 22. A lifting handle 233, coaxially arranged with the gear 232, is also provided on the sliding assembly 22. When the position of the sliding assembly 22 needs to be adjusted, the operator can drive the gear 232 to rotate through the lifting handle 233. The interaction between the gear 232 and the rack 231 causes the sliding assembly 22 to slide along the height direction of the support column 21, making the position adjustment of the sliding assembly 22 more convenient and faster.

[0043] It should be noted that there can be multiple gears 232, which together form a gear set. For example, two gears 232 can be used, both of which are rotatably mounted on the sliding assembly 22 and mesh with each other. The diameter of the first gear 232 is larger than that of the second gear 232. By meshing the first gear 232 with the rack 231 and coaxially arranging the lifting handle 233 with the second gear 232, the movement of the sliding assembly 22 is made easier and less strenuous.

[0044] In an optional embodiment, please refer to Figure 3 A positioning component 234 can also be provided on the sliding assembly 22, which can fix the sliding assembly 22 and the support column 21 to each other. The positioning component 234 can be a positioning screw threadedly connected to the sliding assembly 22. The position of the positioning screw can be adjusted by rotating it, so that the positioning screw moves away from or closer to the support column 21. When the sliding assembly 22 needs to be fixed, the positioning screw can be rotated so that one end of the positioning screw abuts against the support column 21. The friction force keeps the support column 21 and the sliding assembly 22 fixed, making the fixing of the sliding assembly 22 more convenient and secure.

[0045] In one embodiment, see Figure 2 and Figure 5The switchgear switching operation device also includes a control unit 6 and a control terminal. The control unit 6 is electrically connected to the control terminal of the drive motor. The control unit 6 is used to control the working state of the motor, and the control terminal is communicatively connected to the control unit 6 to send control commands to the control unit 6. Specifically, the control unit 6 refers to a component that can control other devices according to commands. The control unit 6 can be an MCU (Microcontroller Unit), a PLC (Programmable Logic Controller), or a computer, etc., and the specific form of the control unit 6 is not limited here. The control terminal refers to a component that can send commands to the control unit 6. The control terminal is generally wirelessly connected to the control unit 6 through a wireless communication module. In this embodiment, the wireless transmission method is not specifically limited. The control terminal can be a remote control, a mobile phone, a tablet computer, etc., and is not specifically limited here. In this embodiment, the control unit 6 can be electrically connected to the control terminal of the drive motor, and the control terminal can be communicatively connected to the control unit 6. Thus, commands can be remotely sent to the control unit 6 through the control terminal, and the working state of the motor can be controlled by the control unit 6, such as controlling the forward or reverse rotation of the motor, to realize the entire switching operation. This allows operators to stay away from dangerous areas, thereby making the switching operation safer and more reliable.

[0046] Furthermore, in this embodiment, the operator manually adjusts the position of the base 1 and the height of the crossbeam 3 to match the position of the operating handle 41 with the trolley operating hole. Then, the switching operation is performed remotely via a control terminal. This human-machine combination approach, with manual assistance, replaces manual operation with machine intervention. This avoids the safety risks associated with manual operation while also offering the advantages of simple equipment structure and lower cost. It further improves the safety of personnel in high-voltage switchgear switching operation applications.

[0047] In one embodiment, see Figure 2 , Figure 5 as well as Figure 6 A torque sensor is provided between the drive end of the drive motor and the operating handle 41. The torque sensor is used to detect the torque at the operating handle 41. The control unit 6 is electrically connected to the torque sensor. The control unit 6 is used to obtain the number of rotations of the rotor of the drive motor. The control unit 6 is also used to obtain the detection value of the torque sensor and control the working state of the drive motor according to the detection value.

[0048] In this embodiment, the torque sensor is a component that can measure the magnitude of the torque applied to an object. The torque sensor is installed on the drive end of the drive motor and the operating handle 41, and is electrically connected to the control unit 6. The specific workflow of the switchgear switching operation device is as follows: After the operator completes the preparation work, they remotely start the operation on the control terminal. After receiving the start command, the control unit 6 needs to judge the data from the torque sensor. The controller controls the motor to rotate according to the received forward or reverse rotation command. When the torque sensor data increases to a set threshold, it indicates that the switchgear has reached the predetermined position and the motor has rotated within the preset range. If the two states do not match, it indicates that the switchgear cannot reach the predetermined position due to an abnormal state. In this embodiment, the torque sensor setting can be used to detect whether the switchgear cannot reach the predetermined position due to an abnormal state, thereby making the use of the entire switchgear switching operation device safer and more reliable.

[0049] It should be noted that a motor driver can also be installed between the control unit 6 and the drive motor, which can make the motor control more convenient and further improve the intelligence of the switching operation.

[0050] In one embodiment, see Figure 2 and Figure 5 The switchgear switching operation device also includes an alarm unit 7, which is electrically connected to the control unit 6. Specifically, the alarm unit 7 is a component capable of emitting an alarm, which can do so by emitting sound, light, or vibration. In this embodiment, by electrically connecting the alarm unit 7 to the control unit 6, if the trolley fails to reach the predetermined position due to an abnormal condition, the control unit 6 sends an alarm signal to the alarm unit 7, causing the alarm unit 7 to sound an alarm to alert the operator. The operator can then determine whether to continue operation or take emergency measures based on the alarm.

[0051] It should be noted that the alarm unit 7 can be installed on the crossbeam 3 or on the control terminal. Alternatively, the alarm unit 7 can be installed on both the crossbeam 3 and the control terminal.

[0052] In an optional embodiment, please refer to Figure 5 Alarm unit 7 is an audible and visual alarm that alerts operators by emitting light and sound, thus making the alarm effect more obvious.

[0053] In one embodiment, see Figure 2 and Figure 5A camera unit 8 for acquiring images of the working area is installed on the crossbeam 3. The camera unit 8 is electrically connected to the control unit 6, and an image display unit for displaying the images is also provided on the control terminal. Specifically, the camera unit 8 is a component that can acquire images or videos within a specified area. The camera unit 8 can be directly installed on the crossbeam 3, or it can be connected to the crossbeam 3 through other components, such as a gooseneck bracket, so that the position of the camera unit 8 can be adjusted as needed. The image display unit is a component that can display images, and it is generally a screen. In this embodiment, by installing the camera unit 8 on the crossbeam 3, the status of key signs at the switch cabinet can be captured, and the captured images can be transmitted to the image display unit, allowing the operator to see the video images through the image display unit so that the operator can take necessary control operations based on the video.

[0054] In one embodiment, see Figure 2 and Figure 5 A power supply unit 9 is provided on the base 1. The power supply unit 9 is electrically connected to the control unit 6, drive motor, torque sensor, camera unit 8, and alarm unit 7. The power supply unit 9 can be a battery. It can also be equipped with quick-connect connectors, which allow the power supply unit 9 to be connected to other devices while the support column 21 is being disassembled and installed.
