Description

Technical Field

[0001] The present invention relates to the technical field of line migration in a distribution network, and in particular to an auxiliary tool and method for distribution line migration under uninterruptible power supply. Background Art

[0002] In the process of urban development and power grid construction, it is often necessary to relocate existing overhead lines, especially when the pole tower position and line path need to be relocated in a small range due to factors such as road construction and municipal planning. The 10kV distribution line and the 0.4kV low-voltage line at the bottom of the tower are completed without power outage. In the existing technology, the pole tower adjacent to the relocated section is converted into a tension pole tower, and then the lead wire with a switch is connected to complete the relocation. In order to facilitate the subsequent connection of the new conductor and the lead wire, it is necessary to install a branch cross arm for fixing the new conductor and the lead wire on the pole tower adjacent to the relocated section. After the line relocation is completed, the branch cross arm needs to be removed. In addition, the branch cross arm is connected by bolts and clamps. Since the disassembly and assembly of the branch cross arm are all carried out at high altitude, this method is relatively troublesome. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides an auxiliary tool and method for distribution line migration under uninterruptible power supply, which has the advantage of easy operation.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] An auxiliary tool for the migration of distribution lines under uninterrupted power supply, comprising a lifting bracket which is sleeved on a pole tower and can be lifted and lowered along the pole tower; a lifting lug is formed on the lifting bracket to facilitate lifting and lowering using a pulley and a pull rope; a wire end limit seat and a plurality of lead end limit assemblies are provided on the lifting bracket; a plurality of wire insertion holes are formed on the wire end limit seat for the wire end to be inserted from top to bottom; the lead end limit assembly comprises a lead end clamping seat and a lead end limit piece; a lead end slot for the lead end to be inserted is formed on the lead end clamping seat; the lead end limit piece is used to limit the lead end within the lead end slot.

[0006] By adopting the above technical scheme, the end of the conductor is inserted into the wire insertion hole of the conductor end limit seat from top to bottom, and the end of the lead wire is inserted into the lead end plug of the lead end clamp, and then the lead end limiter is used to limit it, so that the lead wire and the conductor are connected to the lifting bracket, and then with the help of the pulley installed on the original branch cross arm at the top of the tower and the pull rope passing through the pulley, one end of the pull rope is fixed to the lifting ear, and then the lifting bracket is driven to rise to a suitable height by pulling the other end of the pull rope, which is convenient for the operator to take the ends of the lead wire and the conductor later, and finally the pull rope is loosened. The lifting bracket drops due to its own weight, so there is no need to disassemble and assemble the branch cross arm at high altitude, which is convenient to operate. At the same time, the lifting bracket can be required to stay at any height, and there is no need to loosen and tighten the bolts like the branch cross arm to achieve the above effect, which is more flexible to use; in addition, compared with the existing pull rope pulling the conductor to a specified height, the lifting bracket is used to constrain the position of the conductor end to prevent it from shaking, so that it is convenient for subsequent operators to take it; in addition, the lifting bracket can also be used as a tool for transporting other materials, and has a wider range of applications.

[0007] Optionally, the lead end stopper includes:

[0008] Connecting plate;

[0009] A limiting bolt vertically passes through the connecting plate and is screwed onto the lead end holder;

[0010] The limiting column is formed on the connecting plate and is used to compress the lead wire passing through the lead wire end slot.

[0011] By adopting the above technical solution, the end of the lead is inserted into the lead end slot of the lead end holder, and then the limit bolt is loosened to rotate the connecting plate. During the rotation of the connecting plate, the limit column presses the part of the lead located outside the lead end slot, so that the end of the lead is restricted and is not easy to disengage from the lead end slot, which is convenient for operation. In addition, the lead end can be disengaged from the lead end holder without completely unscrewing the limit bolt, reducing the possibility of the limit bolt falling from a high altitude.

[0012] Optionally, the lead end slot is arranged away from an end opening of the connecting plate.

[0013] By adopting the above technical solution, the lead end slot is arranged away from the opening at one end of the connecting plate, so that when the lead is connected to the lead end socket, the lead can enter the lead end slot from the side opening of the lead end slot without passing through the entire lead end slot, which is more convenient to operate.

[0014] Optionally, a circular lead sliding groove is formed on the limiting column; the axial direction of the lead sliding groove is parallel to the opening direction of the lead end slot away from the connecting plate.

[0015] By adopting the above technical solution, when the limiting column presses the lead wire, the lead wire is located in the lead wire sliding groove of the limiting column, so that the lead wire is not easy to slide out along the opening of the lead wire sliding groove.

[0016] Optionally, the lead end limiting assembly also includes a support seat fixed on the lifting bracket, a connecting column rotatably connected to the support seat, and a limiting member for limiting the rotation angle of the connecting column; the lead end clamp is connected to one end of the connecting column away from its rotation axis.

[0017] By adopting the above technical scheme, the connecting column can be rotated and matched with the limit piece to make the connecting column vertically downward and horizontally outward; when the connecting column is vertically downward, the connecting column and the lead end socket can be used as support feet to support the lifting bracket, so that the operator does not need to operate on the ground, which is convenient for operation; when the connecting column is horizontally outward, the lead end socket can be close to the tension wire clamp of the tension insulator string installed at the lead end, which is beneficial for subsequent operation.

[0018] Optionally, an adjusting rod is formed on one end of the lead end socket close to the connecting column; the adjusting rod is telescopically arranged on the connecting column; and a telescopic limiter for controlling the telescopic length of the adjusting rod is arranged on the lead end socket.

[0019] By adopting the above technical solution, the cooperation of the adjusting rod, the connecting column and the telescopic limiter can control the extension length of the adjusting rod within a certain range, thereby controlling the horizontal position of the lead end socket when it is horizontally facing outward, so as to adapt to different installation positions of the lead end and have a wider range of applications.

[0020] Optionally, the lifting bracket is provided with a central opening for the pole tower to vertically pass through; the lifting bracket is provided with a guide assembly; the guide assembly includes a plurality of guide rollers located in the central opening; and the guide rollers abut against the side walls of the pole tower.

[0021] By adopting the above technical solution, when working, all the guide rollers are against the side walls of the tower, so that the lifting bracket will not swing accidentally during the lifting process, and the operation safety is higher.

[0022] Optionally, the guide assembly also includes a plurality of roller frames and a displacement adjustment member; the guide rollers correspond to the roller frames one by one and the guide rollers are rotatably connected to the roller frames; the roller frames are movably arranged on the side walls of the center opening close to the pole tower; the displacement adjustment member is used to synchronously drive all the roller frames away from or close to the pole tower.

[0023] By adopting the above technical solution, the displacement adjustment member can synchronously drive all roller frames to move away from or approach the pole tower, so that the lifting bracket can use pole towers with different diameters and has a wider range of applications.

[0024] Optionally, the lifting bracket is formed by a pair of combined brackets that are detachably connected, each of the combined brackets is provided with a notch, and the notches on the pair of combined brackets cooperate to form a central opening for the tower to pass through.

[0025] By adopting the above technical solution, the lifting bracket can be split into a pair of combined brackets, and then a pair of combined brackets are located on both sides of the pole tower, and then the pair of combined brackets are close to each other, so that the pole tower enters the central opening formed by the notches of the pair of combined brackets, so that the lifting bracket and the pole tower can be coordinated more conveniently.

[0026] A method for migrating a power distribution line under uninterruptible power supply comprises a wire lifting step and a wire lowering step; the wire lifting step and the wire lowering step use the above-mentioned auxiliary tool.

[0027] By adopting the above technical solution, there is no need to disassemble and assemble the branch crossarm for transition on the pole tower, which reduces the workload of high-altitude operations and improves the operability and installation performance; in addition, the required lead wires and conductors can be driven up to the working position together, which is more efficient, and at the same time, the lead wires and conductors are restricted to facilitate the operator to take them.

The shape of the combined bracket 10 can be "U"-shaped or semi-circular arc-shaped; when the shape of the combined bracket 10 is "U"-shaped, the lifting bracket is in a square frame shape; when the shape of the combined bracket 10 is semi-circular arc-shaped, the lifting bracket is in a circular ring shape; considering the connection of other subsequent components, the "U"-shaped combined bracket 10 is the best, and in the following elaboration process, it will be expanded with this shape.

[0040] Refer to Figure 1 , several lifting lugs 11 are welded on the upper end face of the combined bracket 10. In this way, during use, a pulley is installed on the original branch cross arm at the top of the utility pole, a pulling rope is installed on the pulley, and one end of the pulling rope is fixedly connected to the lifting lug 11. In this way, the entire lifting bracket can be lifted by the pulling rope.

[0041] Refer to Figure 1, a wire end stopper 13 is fixed to one end of the combined bracket 10 away from the opening thereof; a plurality of wire insertion holes 130 with upper and lower openings are formed on the wire end stopper 13; a plurality of lead wire end stopper assemblies 20 are connected to the end surface of the wire end stopper 13 away from the combined bracket 10. In order to avoid interference between the lead wire and the wire, the lead wire end stopper assemblies 20 are divided into two groups and are located on both sides of the wire insertion hole 130. When in use, the wire end is inserted into the wire insertion hole 130 from top to bottom. At this time, the wire end is located on the upper side of the lifting bracket, the lead wire end is connected to the lead wire end stopper assemblies 20, and the lead wire is located on the lower side of the lifting bracket.

Of course, in this embodiment, in order to make the limiting more stable, a pair of limiting threaded holes cooperating with the limiting bolt 24 are formed on the outer surface of the connecting column 23. When the end of the limiting bolt 24 is screwed into one of the limiting threaded holes, the connecting column 23 is vertically arranged; when the end of the limiting bolt 24 is screwed into the other limiting threaded hole, the connecting column 23 is horizontally arranged. In order to facilitate the overall movement of the lifting bracket, a universal wheel 28 is installed on the end surface of the lead end clamp 26 away from the connecting column 23, so that when the connecting column 23 is vertically arranged, the universal wheel 28 is arranged on the ground.

[0044] refer to Figure 2 , Figure 4 and Figure 5 A lead end slot 260 is formed on the lead end holder 26; the lead end slot 260 penetrates the lead end holder 26; the lead end slot 260 is for the lead end to be inserted; in order to facilitate the lead end to enter the lead end slot 260, an opening is set at one end of the side wall of the lead end slot 260, that is, the cross-section of the lead end slot 260 is U-shaped, and the lead end can enter the lead end slot 260 from the lateral opening of the lead end slot 260, which is more convenient than passing through along the penetration direction of the lead end slot 260.

[0045] In order to make the lead state close to the installation state, refer to Figure 2 and Figure 4 The penetration direction of the lead end slot 260 is not perpendicular to the lead end holder 26, but is at an angle to the length direction of the lead end holder 26.
