When the push rod 2 moves in the positive direction relative to the lower clamping port 102 and the upper clamping port 103 to form the installation wire, the movable arm 105 will rotate clockwise, driving the clamping arm 101 to rotate counterclockwise, and the upper clamping The opening 103 will move upwards, and the distance from the lower clamping opening 102 will continue to increase, and the function of releasing the wire will be completed; The movable arm 105 will rotate counterclockwise, driving the clamping arm 101 to rotate clockwise, the upper clamping port 103 will move downward, and the distance between the lower clamping port 102 will be continuously reduced, and the function of clamping the wire will be completed ;

In this embodiment, the wire clamp 1 not only has the basic functions and structures of common wire clamps on the market, but also has a threaded hole on the lower clamping port 102 on the wire clamp 1 for connecting with the second connector 301 The movable arm 105 on the wire clip 1 has a threaded hole for hinged connection with the first connector 201, and the push rod 2 can rotate around the movable arm 105.

In this embodiment, the whole part of the wire clamp 1 is cast from gray cast iron, so as to bear the tension during the line tightening process.

In this embodiment, the number of the first rod body 202 in the push rod 2 is not fixed, and can be selected according to the actual situation in the maintenance process. The first rod body 202 is set in multiples, and the plurality of first rod bodies 202 are connected in sequence. The length of the first rod body 202 is set according to actual needs, and can be 300 mm, or other values. The utility model does not make specific limitations. The front end of the first rod body 202 is provided with a threaded column, and the rear end of the first rod body 202 is provided with a threaded hole. Multiple first rods 202 can be used for the first connection. When the space required for work is large, four first rods 202 can be used for connection, and the working distance of the tight line can be extended to 1.2m; however, in the actual process, generally Using two first rod bodies 202 for connection, the working distance range of wire tightening is expanded to 0.6m, and the wire tightening task can be completed.

In this embodiment, the pull rod 3 can rotate around the lower thread clamp port 102. The stopper 305 in the pull rod 3 is different from the traditional thread clamp stopper on the market. The traditional thread stopper on the market is located at the On the substrate of the upper clamping port 103 of the device or on the upper base of the lower clamping port 102, the disadvantage is that the blocking piece 305 is often easy to shake during the operation process of clamping the line, so that the position of the blocking piece 305 is shifted, It does not have the function of restricting the position of the wire. Once the wire clamp shakes, it is very easy to cause the wire to fall off. In the present utility model, the retaining piece 305 is fixedly connected by two bolts and the head of the second rod body 302 directly connected with the second joint, because the second joint 301 can rotate around the movable arm 105, when there is no tight line During operation, there is no need to restrict the position of the wire, the position of the stopper 305 is not restricted, and the second connector 301 can be rotated arbitrarily around the lower clamping port 102 without any restriction; The position is limited. At this time, the second connector 301 is rotated so that the blocking piece 305 is always in the gap position with the upper and lower clamping openings of the wire tensioner, and the position of the wire is limited.

In this embodiment, the cross-section of the short wire tube 304 in the pull rod 3 is a notched cylinder with a hole, the size of the gap is larger than the diameter of the wire, the wire can be put into the cylinder with a hole, and when the wire is tightened, It takes a lot of physical effort for the operator to hold the wire tensioner all the time, and the 304 wire short tube can hang the wire tensioner on the wire through the cylinder with holes to reduce manual physical exertion.

In this embodiment, the number of the second rod body 302 in the pull rod 3 is not fixed, and can be selected according to the actual situation in the maintenance process. The second rod body 302 can be set in multiples, and the multiple second rod bodies 302 are connected in sequence. The length of the rod body 302 is set according to actual needs, which can be 300mm, or other values. The second rod body 302 can be connected at the first position. When the space required for operation is large, four second rod bodies 302 can be used for connection, and the distance range of the tight line operation can be extended to 1.2m; A second rod body 302 is connected, and the line tightening operation distance range is expanded to 0.6m, which can complete the line tightening task.

The working principle and application process of the utility model: when in use, before the wire tightening operation, it is necessary to select the length of the push rod 2 and the pull rod 3 according to the required length range, which is generally 0.6m, and first install two sections of the first rod body 202 or the second rod body 302, after selecting the length, assemble the push rod 2 and the pull rod 3 according to Figure 3 and Figure 4; then assemble the push rod 2, pull rod 3 and wire clamp 1 respectively to complete the assembly of the wire tensioner After work, carry out the wire tightening operation on the wire;

First of all, the worker first climbs up a section of the electric pole to fix one end of the electric wire, and then climbs up another electric pole with the other end of the electric wire. 2 Move to allow the movable arm 105 to rotate, so that the wire clamp 1 clamps the wire, or directly rotate the movable arm 105, so that the wire clamp 1 clamps the wire, and then the pull rod 3 will be rotated, and the stopper on the pull rod 3 305 also rotates, and rotates to the clamping mouth of wire clamp 1, and radially limits the electric wire. At the same time, the wire is put into the short wire tube 304 on the pull bar 3, and the wire clamp can be hung on the wire. In this way, workers do not need to pick up the wire clips, reducing the physical exertion of manual work at high altitudes;

The worker cooperates with the ratchet wire tensioner to complete the next operation, and connects the hook of the ratchet wire tensioner with the center hook of the movable arm 105 of the wire clamp 1. After the connection is completed, the swing bar of the ratchet wire tensioner is continuously rotated to Wires are clamped. In the traditional tight wire, because the wire is very long, the above process is repeated three to five times before the wire can reach the required tight wire level. And use the tightening auxiliary tool in this design, after finishing the clamping of wire clamp 1 pair of electric wires, can change the position of clamping electric wire; Rotate, drive the clamping arm 101 to rotate counterclockwise, the upper clamping port 103 will move upwards, and the distance from the lower clamping port 102 will continue to increase, so that the wire clamp 1 releases the wire, and then move the wire clamp 1 to Appropriate place, because wire clip just can be hung on the electric wire, be easy to finish the loosening of clamping mouth and the movement of clamping mouth at this moment, then, the worker puts push rod 2 relative to lower clamping mouth 102 and upper clamping wire When the port 103 forms the installation wire and moves in the positive direction, the movable arm 105 will rotate counterclockwise, and the clamping arm 101 will be driven to rotate clockwise, and the upper clamping port 103 will move downward, and the distance between the lower clamping port 102 Decrease continuously to finish clamping the wire;

Since the position of the clamping port is moved farther, when using the ratchet wire tensioner to tighten the wire, the operation of tightening the wire can be completed at one time, instead of repeating the traditional method many times to achieve the degree of wire tightening , thereby increasing work efficiency.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacements and modifications, the scope of the present utility model is defined by the appended claims and their equivalents.
