[0002] In the daily operation and maintenance of high-voltage switchgear, traditional trolley handle devices present numerous inconveniences and safety hazards. Traditional handles are mostly fixed structures, requiring operators to be in close, direct contact with the switchgear. In confined spaces, this not only makes operation difficult but also increases the risk of electric shock and other accidents if an error occurs, threatening the operator's life. Furthermore, in special operating conditions, such as when there are obstacles or high temperatures around the switchgear, or when a malfunction occurs during operation leading to an explosion or fire, close-range, frontal operation further increases the risks and difficulty.

[0003] In summary, existing technologies have the problem that when personnel switch the working status of high-voltage switchgear at close range, a high-voltage switchgear malfunction can cause a frontal impact that can lead to personnel injury. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage switchgear trolley handle device based on a universal joint, which solves the problem in the prior art where personnel are injured by frontal impact caused by high-voltage switchgear malfunctions when switching the working state of the high-voltage switchgear at close range.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] A high-voltage switchgear trolley handle device based on a universal joint includes a liftable trolley base 2, on which a universal joint-based handle device 1 is mounted, and the universal joint-based handle device 1 is fixedly connected to the liftable trolley base 2.

[0025] The height-adjustable trolley base 2 includes a trolley body with wheels at the bottom. A universal joint-based handle device 1 is mounted on the trolley body. The trolley body includes a first support frame 26. Braked free wheels 24 are located at both ends of one side of the bottom of the first support frame 26, and free universal wheels 25 are located at both ends of the other side of the bottom of the first support frame 26. The free universal wheels 25 and the braked free wheels 24 are configured to cooperate. The upper part of the first support frame 26 is fixedly connected to a second support frame 27 via several support rods 23. The first support frame 26 and the second support frame 27 are arranged parallel to each other. A fixed panel 21 is located on the upper part of the second support frame 27. The fixed panel 21 is connected to the second support frame 27 via several lifting bolts 22. The angle between the plane of the fixed panel 21 and the plane of the second support frame 27 is adjusted by the lifting bolts 22. Several mounting holes 14 are formed on the fixed panel 21, and the mounting holes 14 are configured to cooperate with the fixed base 13.

[0026] The universal joint-based handle device 1 includes a telescopic rod 12, one end of which is connected to a handle 11, and the other end of which is connected to one end of a double universal joint coupling 15. The other end of the double universal joint coupling 15 is connected to one end of a crank handle 16, and the other end of the crank handle 16 is fitted into a high-voltage switchgear. Several fixing seats 13 are fitted onto the telescopic rod 12, and these fixing seats 13 are fitted into a fixing panel 21. The fixing seats 13 are bolted to the mounting holes 14 on the fixing panel 21. Similarly, several fixing seats 13 are fitted onto the crank handle 16, and these fixing seats 13 are bolted to the mounting holes 14 on the fixing panel 21.

[0027] When using this utility model, push the liftable trolley base 2 to the vicinity of the high-voltage switchgear to be operated. Select a suitable sleeve according to the size and model of the control hole of the high-voltage switchgear and install the sleeve on the front end of the crank handle 16. Then insert the crank handle 16 with the sleeve installed into the control hole of the high-voltage switchgear. At this time, the liftable trolley base 2 is located in front of the high-voltage switchgear, and the operator is located at the handle 11, i.e., the side of the high-voltage switchgear. Rotate the handle 11, and the handle 11 will drive the telescopic rod 12 and the double universal joint coupling 15 in sequence to rotate the crank handle 16. The crank handle 16 drives the stud in the control hole of the high-voltage switchgear to rotate, thereby changing the working state of the high-voltage switchgear. If the high-voltage switchgear malfunctions and causes a frontal impact, the operator can avoid being injured by the impact because the operator is located on the side of the high-voltage switchgear, thus ensuring the safety of the operator.

[0028] This utility model mounts the fixing base 13 onto the fixing panel 21 of the trolley via mounting holes 14. During installation, according to the preset mounting hole layout on the fixing panel 21, a suitable mounting hole 14 is selected, and the fixing base 13 is firmly fixed using matching bolts, nuts, and other connecting parts to ensure that the entire device will not loosen during subsequent use.

[0029] The operator adjusts the length of the telescopic rod 12 according to the actual operating distance requirements. For example, when there are obstacles between the operator and the high-voltage switchgear, making operation impossible at the normal distance, the telescopic rod 12 can be extended to increase the distance between the handle 11 and the trolley, enabling remote operation. During adjustment, the telescopic structure inside the telescopic rod 12 can be used to adjust the length through methods such as plugging, pulling, and rotating to lock, ensuring that the adjusted length is stable and reliable.

[0030] For lateral operation, the double universal joint coupling 15 plays a crucial role. Because the double universal joint coupling 15 can rotate freely in multiple directions, the operator can flexibly adjust the angle of the handle 11 according to the actual operating environment and their own position. For example, when one side of the high-voltage switchgear has more space than the front, the operator can rotate the handle 11, changing its direction via the double universal joint coupling 15, so that it is aligned with the operating interface of the high-voltage switchgear from the side, thus achieving lateral operation.

[0031] When in use, the crank handle 16 is connected to the corresponding operating part of the high-voltage switchgear. The operator holds the handle 11 and pushes the crank handle 16 back and forth to drive the high-voltage switchgear trolley to perform the corresponding operation. During operation, if the ground is uneven, the height of the trolley can be adjusted by adjusting the lifting bolt 22. In specific operation, use the matching tool such as a wrench to rotate the lifting bolt 22 to raise or lower the support rod 23 of the trolley, thereby adjusting the height of the entire trolley. This ensures that the device can be placed stably on the ground at different heights, adapting to trolley switches of different heights, and avoiding operational difficulties or equipment damage due to uneven ground.

[0032] To ensure safe operation when using this device, the braked caster 24 must be secured before operation. The brake pedal on the braked caster 24 will be pressed to brake it and prevent the trolley from moving unexpectedly during operation. When parking the trolley after operation, it is also necessary to ensure that the braked caster 24 is in the braked state to prevent the trolley from sliding and causing a safety accident.

[0033] The presence of the free-swivel casters 25 makes the trolley more flexible during movement. When the trolley needs to be moved, the brake on the braked caster 24 is released, and the operator can push the trolley. The free-swivel casters 25 can rotate at multiple angles, making it easy for the operator to move the trolley to the required position. Whether in narrow passages or complex work areas, the movement direction of the trolley can be easily controlled.

[0034] When not in use, push the handle 11 and crank 16 back to the fixed position. The fixed position can be set at a specific location on the trolley, such as a specially designed slot or hook. The handle 11 is inserted into the slot or hung on the hook to prevent it from shaking during the movement of the trolley, thus avoiding damage to the device or affecting other work.

[0035] This invention utilizes the flexibility of the universal joint to enable remote operation of the handle 11 from the side, effectively avoiding injury caused by improper operation due to close-range frontal contact, while improving the convenience and flexibility of operation.
