Description

Technical Field

[0001] This utility model relates to the technical field of power distribution conductor lifting devices, specifically a 10kV power distribution conductor lifting device. Background Technology

[0002] A 10kV distribution conductor hoist is a power work device that temporarily lifts or fixes overhead conductors using mechanical or hydraulic principles to facilitate line maintenance, insulator replacement, crossarm installation, and other operations. Its design must meet requirements for insulation, load-bearing capacity, and ease of operation to ensure that conductor damage or electric shock risks are avoided during live-line or de-energized work.

[0003] Existing power distribution conductor lifters are inconvenient for fixing and disassembling conductors, making it difficult to quickly and safely replace porcelain insulators. In addition, the fixing clamps in some existing lifters cannot be adapted to different diameters (e.g., 50mm² and 240mm² conductors require module replacement).

[0004] To address this, this technical solution designs a 10kV power distribution conductor lifting device. Utility Model Content

[0005] The purpose of this invention is to provide a 10kV power distribution conductor lifter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A 10kV power distribution conductor lifting device includes an insulating support rod and a lifting support rod. The insulating support rod and the lifting support rod are longitudinally spaced and the distance between them is adjusted by a threaded lifting component. A conductor fixing groove is opened on one side of the top of the lifting support rod. A set of L-shaped conductor fixing stops is oscillatingly set on the outside of the top of the conductor fixing groove. The power distribution conductor to be lifted is placed in the conductor fixing groove, and then the conductor fixing stops are rotated to limit its position.

[0008] The bottom of the insulating support rod is threaded with a set of insulating support rod positioning screws, and a locking nut is threaded onto the insulating support rod positioning screws. Through the threaded engagement of the insulating support rod positioning screws and the locking nut, the insulating support rod positioning screws are installed into the mounting holes of the insulating support rod positioning screws opened on the porcelain insulator bracket. Then, under the control of the threaded lifting component, the height of the power distribution wire placed inside the wire fixing groove is adjusted, thereby separating the power distribution wire from the mounting hole of the insulating support rod positioning screw. This facilitates the disassembly, maintenance, or replacement of the porcelain insulator from the porcelain insulator bracket. At the same time, the cooperation between the wire fixing groove and the wire fixing stop facilitates the stable clamping and fixing of power distribution wires of different diameters.

[0009] Compared with the prior art, the advantages of this utility model are: by cooperating with the wire fixing groove and the L-shaped stop bar, and by using the swing locking structure to adapt to wires of different diameters, there is no need to replace the module.

[0010] The height of the conductor is adjusted by using a threaded lifting device to separate the power distribution conductor from the porcelain insulator bracket, enabling rapid replacement of the porcelain insulator.

[0011] The symmetrical anti-rotation columns are embedded in the telescopic holes of the insulating support rod to ensure stability during the lifting process.

[0012] The core components are made of silicone rubber / epoxy resin, which meets the insulation requirements for 10kV live-line work.

[0013] The porcelain bottle holder can be quickly positioned and disassembled by using a positioning screw and a locking nut. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-7 A 10kV power distribution conductor lifting device includes an insulating support rod 100 and a lifting support rod 101. The insulating support rod 100 and the lifting support rod 101 are longitudinally spaced and the distance between them is adjusted by a threaded lifting component. A conductor fixing groove 102 is opened on one side of the top of the lifting support rod 101. A set of L-shaped conductor fixing stops 103 are oscillatingly arranged on the outside of the top of the conductor fixing groove 102. The power distribution conductor to be lifted is placed in the conductor fixing groove 102, and then the conductor fixing stops 103 are rotated to limit its position.

[0027] An insulating support rod 100 has a set of insulating support rod positioning screws 109 threaded to its bottom. A locking nut 110 is threaded onto the insulating support rod positioning screw 109. Through the threaded engagement of the insulating support rod positioning screw 109 and the locking nut 110, the insulating support rod positioning screw 109 is installed into the insulating support rod positioning screw mounting hole 123 opened on the porcelain insulator bracket 121. Then, under the control of the threaded lifting component, the height of the power distribution wire placed inside the wire fixing groove 102 is adjusted, thereby separating the power distribution wire from the insulating support rod positioning screw mounting hole 123. This facilitates the disassembly, maintenance, or replacement of the porcelain insulator 124 from the porcelain insulator bracket 121. At the same time, the engagement between the wire fixing groove 102 and the wire fixing stop 103 facilitates the stable clamping and fixing of power distribution wires of different diameters.

[0028] In one embodiment of the present invention, the insulating support rod 100, the lifting support rod 101, the wire fixing stop 103, and the anti-rotation post 111 are all made of insulating materials such as silicone rubber and epoxy resin that are resistant to aging and pressure, so that they still have a good service life and performance when placed outdoors for a long time.

[0029] To prevent the conductor fixing groove 102 from rotating during the lifting of the power distribution conductor, two vertically distributed anti-rotation columns 111 are symmetrically installed on both sides of the threaded lifting component. The bottom end of the anti-rotation column 111 is provided with a telescopic hole in the insulating support rod 100. The anti-rotation column 111 moves synchronously into the telescopic hole as the lifting support rod 101 moves, thereby limiting the rotation of the conductor fixing groove 102.

[0030] In this embodiment of the invention, one end of the wire fixing stop 103 is threadedly hinged to the rod seat 104 located on the top side of the lifting support rod 101 via a screw shaft 105. The swing of the wire fixing stop 103 is controlled by the screw shaft 105, and the rotation of the screw shaft 105 can also be restricted by tightening the screw shaft 105, thereby increasing the fixation of the wire fixing stop 103. A locking pin 107 is installed on the vertical section of the other end of the wire fixing stop 103. An L-shaped notch is opened on the side wall of the lifting support rod 101 corresponding to the locking pin 107. A locking hole 108 is opened in the inner wall of the locking pin 107. The locking pin 107 is engaged into the locking hole 108, and the swinging stop 103 can be fully fixed.

[0031] In one embodiment of the present invention, a porcelain insulator bracket 121 is installed on a power distribution conductor pole. Multiple porcelain insulator mounting holes 122 are provided on one side of the top of the porcelain insulator bracket 121 for mounting and fixing porcelain insulators 124. A power distribution conductor fixing groove 125 is provided on the top of the porcelain insulator 124, and the power distribution conductor is positioned within the power distribution conductor fixing groove 125. Simultaneously, an insulating support rod positioning screw mounting hole 123 is provided on the porcelain insulator bracket 121 on one side of the porcelain insulator mounting hole 122. The insulating support rod positioning screw mounting hole 123 is plugged into and connected to the insulating support rod positioning screw 109. Thus, when lifting the power distribution conductor in the power distribution conductor fixing groove 125, the insulating support rod positioning screw 109 is pre-installed in the insulating support rod positioning screw mounting hole 123 on one side of the porcelain insulator 124. Then, the power distribution conductor is lifted upwards using the conductor fixing groove 102. At this point, the porcelain insulator 124 can be disassembled without affecting the normal support and operation of the power distribution conductor.

[0032] In a preferred embodiment of the present invention, the threaded lifting component includes a hexagonal bolt 117 installed in the middle of the bottom of the wire fixing groove 102. The top of the hexagonal bolt 117 is rotatably connected to the middle of the bottom of the wire fixing groove 102. The bottom of the hexagonal bolt 117 is connected to a top lifting screw 116. The bottom end of the top lifting screw 116 is threadedly connected to a T-shaped screw hole post 114 fixed in the middle of the insulating support rod 100. A top screw hole 115 is opened in the middle of the T-shaped screw hole post 114 corresponding to the top lifting screw 116. That is, by rotating the hexagonal bolt 117, the depth of the top lifting screw 116 placed in the top screw hole 115 is controlled, thereby adjusting the lifting height of the wire fixing groove 102. At this time, the anti-rotation posts 111 on both sides move simultaneously.

[0033] An insulating support rod positioning screw 109 has a bottom screw hole 113 in the insulating support rod 100 corresponding to the top end of the insulating support rod positioning screw 109. The insulating support rod positioning screw 109 is threaded into the bottom screw hole 113 and is used to adjust the extension length of the insulating support rod positioning screw 109. That is, when the insulating support rod positioning screw 109 is inserted into the insulating support rod positioning screw mounting hole 123, the installation and removal of the insulating support rod positioning screw 109 and the insulating support rod positioning screw mounting hole 123 can be quickly controlled by rotating and locking the locking nut 110.

[0034] The positioning between the power distribution wire fixing groove 125 and the power distribution wire, as well as the installation connection between the bottom of the porcelain insulator 124 and the porcelain insulator mounting hole 122, can be achieved using existing conventional structures and principles, and will not be elaborated here, but this does not affect the integrity of this technical solution.

[0035] The operation process of this lift is as follows:

[0036] Installation and positioning: Screw the insulating support rod positioning screw 109 into the mounting hole 123 of the porcelain bottle bracket 121, and tighten the lock nut 110 to fix the position.

[0037] Adjust the bottom screw hole 113 at the bottom of the insulating support rod 100 to adjust the length of the positioning screw 109.

[0038] Wire fixing: Place the power distribution wire into the wire fixing groove 102 of the lifting support rod 101.

[0039] The swing guide is fixed to the stop bar 103 in the closed position, so that the locking pin 107 engages with the locking hole 108 on the side wall of the lifting support rod 101 and locks it in place. Figure 4 .

[0040] Wire lifting: Rotate the hexagonal bolt 117 to drive the top lifting screw 116 to rise and fall within the top screw hole 115 of the T-shaped screw hole column 114, thereby causing the lifting support rod 101 to move upward.

[0041] The anti-rotation column 111 moves synchronously along the telescopic hole of the insulating support rod 100 to prevent rotation. Figure 2 .

[0042] Porcelain insulator replacement: After the wire is lifted, it separates from the porcelain insulator bracket 121, and the porcelain insulator 124 is disassembled for repair and replacement. Figure 6 .

[0043] Reset and disassembly: Rotate the hex bolt 117 in the reverse direction to lower the wire, unlock the lever 103 and remove the wire.

[0044] Loosen the locking nut 110 and remove the positioning screw 109.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
