Description

Technical Field

[0001] The utility model relates to a rotary operating device for a 6KV floor-standing switch cabinet trolley. Background Art

[0002] Many 6kV switches in thermal power plants are floor-standing. The trolley switch weighs more than 300 kilograms and has a high voltage level. To ensure the personal safety of operators, when the trolley switch stops supplying power, operators need to wear insulating gloves and use the trolley switch operating handle to swing in and out. When operators operate, the operating handle is often entangled by the insulating gloves, and they need to stop and rearrange the insulating gloves before continuing to operate. When they stop to rearrange the insulating gloves, the moving and static contacts of the trolley switch have not yet fully contacted, and there is a risk of discharge from the 6kV high-voltage busbar to the moving trolley contacts, which greatly threatens the personal safety of operators.

The Y-shaped fork at one end passes through the adjustment hole on the insertion rod end and is threadedly connected to the locking nut, and the Y-shaped fork at the other end passes through the adjustment hole on the hand-held rod end and is threadedly connected to the locking nut. A swivel ring sleeve is sleeved on the through rod, and a rotating sleeve is connected to the end of the hand-held rod.

[0007] The 6KV floor-standing switch cabinet trolley rotary operating device, the slewing ring sleeve is formed by two semicircular ring plates buckled together, the four corners of the semicircular ring plates are respectively fixed with fixed plates, and the fixed plates are provided with through holes.

[0008] The 6KV floor-standing switch cabinet trolley rotary operating device, the rotary sleeve comprises an outer screw sleeve, a movable sleeve and a plug, the outer screw sleeve is threadedly connected to the hand-held rod end, the movable sleeve is sleeved on the outer screw sleeve, and the plug is threadedly connected to the outer screw sleeve. Beneficial Effects

[0009] 1. The utility model has a swivel ring sleeve on the end of the operating rod, and a rotating sleeve is connected to the hand-held rod end. During operation, one hand holds the swivel ring sleeve part, and the other hand holds the rotating sleeve part to operate, so as to prevent the insulating gloves from being entangled during operation, ensuring that the operating personnel wearing insulating gloves can operate the 6kV high-voltage electrical switch in one go, thereby ensuring the personal safety of the operating personnel.

[0010] 3. The operating rod end of the utility model can be adjusted in position so that it can be installed with adjustment holes at different positions, so that the height of the "X"-shaped arch can be changed, making it suitable for operation by people with different arm lengths.

[0017] Reference Figure 1-Figure 5 A 6KV floor-standing switch cabinet trolley rotary operating device, which comprises a plug-in rod end 1 and a hand-held rod end 3, wherein the plug-in rod end and the hand-held rod end are connected through an operating rod end 2 to form a "X"-shaped structure;

[0018] The operating rod end includes a through rod, and both ends of the through rod are respectively provided with a Y-shaped fork 21. The Y-shaped fork at one end passes through the adjustment hole 8 on the plug rod end and is threadedly connected with the locking nut 7, and the Y-shaped fork at the other end passes through the adjustment hole on the hand-held rod end and is threadedly connected with the locking nut. There are multiple adjustment holes at the plug rod end, and the number of adjustment holes at the hand-held rod end is equal to that of the plug rod end and the positions correspond. A swivel ring sleeve 23 is sleeved on the through rod, and the swivel ring sleeve is formed by two semicircular ring plates 24 buckled together. Fixed plates 6 are respectively fixed at the four corners of the semicircular ring plates, and through holes 25 are provided on the fixed plates. When fixed, the two semicircular ring plates are fixed by fixing bolts 5. The inner diameter of the semicircular ring plate is larger than the outer diameter of the through rod by 0.5-1mm, so that the swivel ring sleeve can rotate freely. The end of the hand-held rod is connected with a rotating sleeve 4.

[0019] The rotating sleeve includes an outer screw sleeve 44, a movable sleeve 42 and a plug 43. The outer screw sleeve is threadedly connected to the end of the hand-held rod, and the movable sleeve is sleeved on the outer screw sleeve. The inner diameter of the movable sleeve is 0.5-1mm larger than the outer diameter of the outer screw sleeve, so that the movable sleeve can rotate freely. The plug is threadedly connected to the outer screw sleeve, and the other end of the outer screw sleeve has a retaining ring 41, and the outer diameter of the retaining ring is smaller than the outer diameter of the movable sleeve.

[0020] Working principle: When in use, insert the rod end of the device into the operating position of the 6KV switch cabinet trolley, then hold the slewing ring sleeve with one hand and the movable sleeve with the other hand to rotate the device. Due to the different arm lengths of different operators, the Y-shaped fork at the end of the operating rod can be inserted into the adjustment holes in different positions to adjust the height of the "X"-shaped arch, which is convenient for different personnel to operate.
