Description

Bolt-On Load Transfer Clamps

technical field

The utility model relates to an improvement of a drainage wire clamp, in particular to a bolt-fastened load transfer wire clamp. It is mainly used in the process of replacing equipment with electricity, transferring loads and hooking up drainage lines.

Background technique

Due to the low insulation level of the distribution network, failures are prone to occur under the influence of atmospheric overvoltage, pollution or other external factors, and the maintenance workload is large, which makes it difficult to meet the requirements of reliable power supply. In order to improve the reliability of distribution network power supply, reduce power failure losses, and improve reliability indicators, live work is an important means of testing, repairing, and transforming power equipment. During live work, it is often necessary to transfer loads to replace faulty equipment. In order to ensure the continuous power supply of the line, the use of the drain line is very frequent. In the past, the drainage wire used a sleeve-type clamp. During the hooking process, the sleeve needs to be unscrewed to realize the connection and fastening of the drainage wire and the wire. It is very inconvenient for the operator to wear insulating gloves during the operation, and the movement range is relatively large. Increased the unsafe factors and difficulty of operation of operators in the operation process.

Another Chinese patent application 2014205302291 of the applicant discloses a "Clamp Type Insulated Drainage Clamp for Load Transfer", which adopts the structural form of two semicircular clips that are buckled oppositely to realize the connection between the insulated drain wire and the 10kV wire connection, the structure is simple, the disassembly is convenient, and the manufacturing cost is low. However, due to the use of movable screw and nut fastening methods, the stability and reliability of the screw are relatively poor, which brings certain difficulties to the construction operation.

Contents of the invention

The purpose of the utility model is to provide a bolt-fastened load transfer clamp with simple structure, convenient disassembly, low manufacturing cost, easy operation, and the clamped wire is not easy to come out.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the bolt-fastened load transfer clamp includes a drain line plate and a handle, and a drain line fixing hole is arranged at the outer end of the drain line plate. An arc-shaped fixed splint is provided between the above-mentioned connecting and draining plate and the handle, and a raised rotating shaft seat is provided on both sides of one end of the arc-shaped fixed splint connected with the connecting and draining plate, and the connecting and draining plate, The handle, the arc-shaped fixed splint, and the rotating shaft seat are integrated, and a through-hole of the fixed splint is provided in the middle of the end connecting the arc-shaped fixed splint and the handle; The arc-shaped rotating splint, the arc-shaped rotating splint and the circular-arc-shaped fixed splint are interlocked to form a cylindrical clamping cavity, and one end of the arc-shaped rotating splint passes through the rotating shaft in the shaft hole through the raised rotating shaft The shaft holes of the seat are fixedly connected together, and the other end of the arc-shaped rotating splint is provided with a movable splint through hole, and the axes of the movable splint through hole and the fixed splint through hole are perpendicular to the axis of the clamping cavity; Fastening bolts are inserted into the through holes of the fixed splint.

A polygonal groove is provided on the outer surface of the arc-shaped rotating splint, and the polygonal groove is concentrically arranged with the through hole of the movable splint. One end of the fastening bolt is provided with a bolt tail end matching the polygonal groove, and the fastening bolt The head end is threadedly connected with a nut.

The beneficial effects of the utility model are: the transfer wire clip has a simple structure, is convenient to disassemble, and has low production cost. .

Detailed ways

As shown in Figure 1 and Figure 2, the bolt-fastened load transfer clamp includes a drain wire plate 1 and a handle 2, and a drain wire fixing hole 3 is provided at the outer end of the drain wire plate 1. An arc-shaped fixed splint 4 is arranged between the drain line plate 1 and the handle 2, and a raised rotating shaft seat 5 is provided on both sides of the end where the arc-shaped fixed splint 4 is connected with the drain line plate 1, and connected Drainage line plate 1, handle 2, arc-shaped fixed splint 4, and rotating shaft seat 5 are integrated, and a fixed splint through hole is provided in the middle of one end of the arc-shaped fixed splint 4 connected to the handle 2; The opposite side of the shaped splint 4 is provided with an arc-shaped rotating splint 7. The arc-shaped rotating splint 7 is buckled with the arc-shaped fixed splint 4 to form a cylindrical clamping cavity 13. The arc-shaped rotating splint 7 One end of one end passes through the shaft hole of the raised rotating shaft seat 5 through the rotating shaft 8 in the shaft hole and is fixedly connected together. The axis of the through hole of the fixed splint is perpendicular to the axis of the clamping cavity 13; the fastening bolt 6 is inserted in the through hole of the movable splint and the through hole of the fixed splint.

A polygonal groove is arranged on the outer surface of the arc-shaped rotating splint 7, and the polygonal groove is arranged concentrically with the through hole of the movable splint. One end of the fastening bolt 6 is provided with a bolt tail end 12 matching the polygonal groove, The head end of the fastening bolt 6 is threadedly connected with a nut 61 .

When it is necessary to transfer the load to replace the faulty equipment with electricity, the operator first loosens the nut 61 in the process of installing the drain wire, takes out the fastening bolt 6, turns the arc-shaped rotating splint 7 upwards, and puts the wire into the arc-shaped fixed splint 4 In the clamping mouth, make the arc-shaped rotating splint 7 turn down again, insert the fastening bolt 6 in the through hole of the movable splint and the through hole of the fixed splint, and tighten the nut 61 from the lower end. Connect the drain wire plate 1 to the drain wire to complete the operation, realize the connection between the insulated drain wire and the 10kV wire, and transfer the equipment load to the insulated drain wire, so that the live working time and the unsafe factors of the workers can be reduced. Improve the reliability of distribution network power supply.
