Description

Technical Field

[0001] The utility model relates to the technical field of electric power operation, in particular to a bypass flexible cable insulation laying rack. Background Art

[0002] Currently, the integrated non-stop operation method for distribution networks balances power supply reliability with public needs, offering a new maintenance method and resolving the conflict between the difficulty of performing power outages for troubleshooting and the necessity of maintenance. While the integrated non-stop operation method has essentially achieved full-service maintenance capabilities at 10kV, it requires the use of bypass flexible cables. Currently, bypass flexible cables are laid using bypass flexible cable covers and moisture-proof canvas. However, in complex terrain such as farmland and green belts along the route, this can cause significant damage to crops and vegetation, increasing the cost of maintenance operations. With accelerating urbanization, the volume of bypass flexible cable laying operations is increasing, and with it, the use of cable insulation support frames.

To address this issue, a bypass flexible cable insulation support frame has been developed. Using this tool can reduce environmental damage at the worksite, reduce the need for cable covers and moisture-proof canvas, and conserve personnel energy. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A bypass flexible cable insulation laying rack includes a bypass flexible cable insulation support rack insulation circular tube 1 and a bypass flexible cable insulation support rack insulation rectangular tube 2. The top assembly method of the bypass flexible cable insulation support rack is that one end of the two bypass flexible cable insulation support rack insulation rectangular tubes 2 are respectively fixed to the insulation rectangular tube joint 1 3 and the insulation rectangular tube joint 2 4, and the insulation rectangular tube joint fixing flange 5 passes through the insulation rectangular tube joint 1 3 and the insulation rectangular tube joint 2 4 and is fixed to the bypass flexible cable insulation support rack insulation circular tube 1. The two bypass flexible cable insulation support rack insulation rectangular tubes 2 can be expanded to an angle of up to 60 degrees with the insulation rectangular tube joint fixing flange 5 as the center.

[0022] The method of assembling the middle and end frames of the bypass flexible cable insulation laying rack is that the insulating round tube fixing tube 12 passes through the insulating round tube 1 of the bypass flexible cable insulation support rack and is fixed. One end of the insulating round tube fixing tube 12 with a flange is fixed to one side of the insulating rectangular tube 2 of the bypass flexible cable insulation support rack, and the other side is fixed with a locking pin fixing flange 9.

[0023] The method of assembling the frames on both sides of the bypass flexible cable insulation laying frame is as follows: the longitudinal horizontal side fixing plates 6 are fixed to the locking pin fixing flanges 9 on the insulating rectangular tube 2 (connected with the insulating rectangular tube joint 2 4) of the bypass flexible cable insulation support frame by bolts, and the longitudinal horizontal side fixing plates 2 7 are fixed to the locking pin fixing flanges 9 on the insulating rectangular tube 2 (connected with the insulating rectangular tube joint 3) of the bypass flexible cable insulation support frame by bolts, and the longitudinal horizontal side fixing plates can rotate around the locking pin fixing flanges 9.

[0024] When the bypass flexible cable insulation laying frame is merged, one end of the longitudinal horizontal two side fixing plates 6 is fixed to the locking pin fixing flange 9 on the bypass flexible cable insulation support frame insulation rectangular tube 2 (connected with the insulation rectangular tube joint 2 4) by bolts, and the other end is fixed to the same flexible cable insulation support frame insulation rectangular tube 2 by a locking pin 8.

[0025] One end of the two longitudinal horizontal fixing plates 7 is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 (connected with the insulating rectangular tube joint 3) of the bypass flexible cable insulation support frame by bolts, and the other end is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 of the same flexible cable insulation support frame by a locking pin 8.

[0026] When the bypass flexible cable insulation laying frame is folded and unfolded, one end of the longitudinal horizontal fixed plates 6 is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 of the bypass flexible cable insulation support frame (connected with the insulating rectangular tube joint 2 4) by bolts, and the other end is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 of the other flexible cable insulation support frame by a locking pin 8.

[0027] One end of the two longitudinal horizontal fixing plates 7 is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 (connected with the insulating rectangular tube joint 3) of the bypass flexible cable insulation support frame by bolts, and the other end is fixed to the locking pin fixing flange 9 on the insulating rectangular tube 2 of another flexible cable insulation support frame by a locking pin 8.

[0028] Two spreading roller frames 10 and three adjustable cable clamps 11 are installed on the insulating circular tube 1 of the bypass flexible cable insulation support frame at the top of the bypass flexible cable insulation laying frame.

[0029] When the flexible cable needs to be dragged, it is placed on the unrolling roller frame 10, which is composed of an unrolling roller arm 20, a U-groove nylon roller 21, and a stud bolt 22. When the flexible cable needs to be fixed, it is placed on the adjustable cable clamp 11. The quick clamp 17 can be adjusted to accommodate different wire diameters. The adjustable cable clamp 11 is composed of the quick clamp 17, an upper clamping block 18, and a lower clamping block 19.

[0030] Four footings 15 are fixed to the insulating rectangular tube 2 of the bypass flexible cable insulation support frame at the bottom end of the bypass flexible cable insulation laying frame. Two nylon directional wheels 16 are fixed above the footings 15 of the insulating rectangular tube 2 of the bypass flexible cable insulation support frame, which are fixed to the longitudinal and horizontal fixing plates 7 on both sides. This makes it easy to carry even in conditions with high terrain requirements. Four steel bar placement modules 13 are installed above the nylon directional wheels 16. When the bypass flexible cable insulation laying frame is not in operation, four steel bar 14 are placed in the four steel bar placement modules 13. When the bypass flexible cable insulation laying frame is in operation, when the bypass flexible cable insulation laying frame is unfolded, the steel bar 14 is removed from the steel bar placement modules 13 and inserted through the holes in the footings 15 to secure the bypass flexible cable insulation laying frame.
