Description

Technical Field

[0001] The invention belongs to the technical field of electric power construction isolation equipment, and in particular relates to an insulating drain wire bracket for live maintenance work. Background Art

[0002] Traditional replacement or maintenance of live equipment work generally requires the load of the equipment to be cut off first. At the same time, in order to ensure the safety of live work, the power supply side lead of the equipment must be removed. With the rapid development of modern industry and the improvement of people's living standards, power users' requirements for power supply reliability are also increasing. In order to reduce power outage time or even no power outage, it is sometimes necessary to carry out load work. Load work refers to the completion of live equipment maintenance work without power outage for power users and load loss of the power grid. In the process of live distribution network work, the insulated drainage wire is often needed. However, when the insulated drainage wire is used, its insulating sheath cannot directly contact the cross arm, and additional insulation shielding is required. Usually, the insulation shielding measures are insulation blankets and brackets. The insulation blanket is large in size, inconvenient to take, and too physically demanding to operate. The current bracket is generally fixed, that is, the fixing point of the insulated drainage wire can only be fixed at a certain position of the cross arm according to the bracket, and the drainage wire laying position cannot be adjusted according to actual operation needs, which has great limitations. Summary of the invention

[0008] A control mechanism is arranged at the front side of the support, and the control mechanism comprises a worm wheel and a worm. The worm wheel is fixedly connected to the active bevel gear, and the worm and the worm wheel are meshed with each other.

[0009] The end of the worm is provided with a turning handle.

[0010] A limiting mechanism is arranged inside the bracket, and the limiting mechanism includes a side plate and a claw. A push rod is arranged on the inner side of the side plate, and fixed hinge shafts are symmetrically arranged on the left and right sides of the push rod.

[0012] The surface of the side plate is provided with a limiting strip, and the side of the clamping claw is provided with a limiting groove.

[0013] The present invention provides an insulated drain wire bracket for live maintenance work, which has the following beneficial effects: through the cooperation of the positioning handle and the positioning gear and the rack, the base can be ensured to be firmly installed on the cross arm, and the sliding or falling off can be prevented during the operation, thereby greatly improving the safety of the operation. The design of the first and second clamping seats, in conjunction with the horizontal clamping plate and the vertical clamping plate, and the support of the clamping mechanism, can tightly fix the device and the cross arm, effectively preventing the drain wire from shaking or falling off during the operation, and further enhancing the safety of the operation.

The design of the limiting mechanism, the limiting strip, and the limiting groove not only enhances the stability of the internal structure of the bracket, but also facilitates the opening and closing operation of the claws, making the fixing and release of the drainage wire faster and preventing the drainage wire from accidentally detaching from the device. The connections between the various components of the device are mostly screwed or meshed, so that they can be easily disassembled and replaced when necessary, reducing maintenance costs and time.

A driven bevel gear 23 is provided on the rear side of the driving plate 22, and the driven bevel gear 23 and the top bevel gear 21 are meshed with each other.

[0032] Furthermore, a control mechanism is disposed on the front side of the support 15 , and the control mechanism includes a worm wheel 24 and a worm 25 . The worm wheel 24 is fixedly connected to the active bevel gear 17 , and the worm 25 and the worm wheel 24 are meshed with each other.

[0033] Furthermore, a handle 26 is provided at the end of the worm 25. The handle 26 facilitates the worm 25 to be rotated.

[0034] When the device is in use, the base 1 is placed steadily above the crossarm to ensure that there is enough contact area between the base 1 and the crossarm. By rotating the positioning handle 2, the positioning gear 3 is driven to rotate, and then the two racks 4 are driven to move synchronously left and right. According to the position and angle of the crossarm, the position of the positioning claw 5 under the rack 4 is adjusted so that it can accurately clamp the crossarm. The adjusting head 12 on the clamping screw 10 is rotated to drive the clamping screw 10 to rotate.

Therefore, the effect achieved is: while the support plate 13 rotates around the support 15, the bracket 14 also rotates around the support plate 13. No matter what angle the support plate 13 rotates to, the opening of the bracket 14 is always facing upward. This structural design is convenient for supporting drainage lines at different positions. This device has significant advantages in improving operational safety, flexibility, adaptability and ease of maintenance, and has a good effect on improving the efficiency and quality of live maintenance operations.
