Abstract

Disclosed is a damper replacer for an overhead ground wire. The damper replacer is provided with a pair of baffles which are connected and oppositely arranged, more than two pulleys are arranged between the two baffles, more than one anti-falling pin penetrates through the positions, below the pulleys, on the two baffles, and the two baffles are respectively provided with a rope-threading hole. Operators can stand on the ground and manually pull the replacer to move on the overhead ground wire after arranging the replacer on the overhead ground wire and putting a rope through the rope-threading holes, and then the replacer pushes against a damper to replace the damper. The damper replacer disclosed by the utility model is simple and reasonable in structure and convenient to operate and can be used to carry out electrical treatment on displacement defect of the damper on the overhead ground wire, outage time of power supply lines can be reduced to the greatest extent, and the reliability of power supply can be improved.

Description

Overhead ground wire stockbridge damper restorer

Technical field

The utility model relates to the maintenance tool that is used for transmission line, specifically a kind of overhead ground wire stockbridge damper restorer.

Background technology

Stockbridge damper is the important protective device on the transmission line, and its effect is inhibition and cuts down because of gentle breeze acts on lead, the caused vibration of overhead ground wire, avoids lead, overhead ground wire to cause wearing and tearing because of vibration.In the circuit running, constantly increase with the circuit operation time limit, the stockbridge damper on the overhead ground wire receives outdoor environment and other multiple factor affecting, it is held put forth effort to reduce and be shifted.For example, the spring pad elasticity of stockbridge damper bolt disappears, and produces the space between bolt looseness post-simulation hammer clamping plate and the steel strand wire, under the situation of ground wire vibrations, slowly slides to sag point, until the sag minimum point.In case stockbridge damper is shifted, not only do not have due antihunt action, even may aggravate vibration, overhead ground wire is caused more serious wearing and tearing, disconnected strand of weight person and even generation, broken string accident, direct threats is to the safe operation of electrical network.

After the overhead ground wire stockbridge damper displacement, is to utilize the charged processing of insulating bar to its means that reset that adopt at present, and stands in by operating personnel that earth potential carries out operation on the shaft tower.Adopt insulating bar to the stockbridge damper deficiency that exists that resets to be: only can handle the nearer defective of stockbridge damper translocation distance, the distance of handling displacement is exceeded with the length of action bars, and it is very limited to handle distance.

The utility model content

The purpose of the utility model is to provide a kind of overhead ground wire stockbridge damper restorer, and this restorer is installed on the ground wire, adopts the hand traction mode to make it move and push stockbridge damper along ground wire, can stockbridge damper be resetted.

For realizing above-mentioned purpose; The utility model adopts following scheme: overhead ground wire stockbridge damper restorer; It has a pair of baffle plate that is coupled to each other and is positioned opposite; At the pulley that is provided with between two baffle plates more than two, the position that is positioned at the pulley below on two baffle plates is coated with the locking pin more than, on two baffle plates, has lacing hole.

Visible by such scheme, under the state that locking pin and baffle plate separate, the pulley between two baffle plates is landed on the overhead ground wire; Then locking pin is installed on two baffle plates again, can accomplishes the setting of this restorer on overhead ground wire, set this restorer after; Reeve lacing hole; Can on overhead ground wire, move by this restorer of hand traction on ground, and then push stockbridge damper, it is resetted by this restorer.

The utility model is simple and reasonable for structure and easy to operate, and it can carry out charged processing to the position defective that stockbridge damper on the overhead ground wire moves, and then has shortened supply line idle time to the full extent, has improved the reliability of power supply.

Description of drawings:

The front view of Fig. 1 the utility model one embodiment and user mode sketch map;

The vertical view of Fig. 2 overhead ground wire stockbridge damper shown in Figure 1 restorer;

The A-A cutaway view of Fig. 3 Fig. 1.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 3

This overhead ground wire stockbridge damper restorer has a pair of baffle plate 1 that is coupled to each other and is positioned opposite, is coated with four locking pins 5 being provided with the position that is positioned at pulley 2 belows on four pulleys, 2, two baffle plates 1 between two baffle plates 1.Locking pin 5 has a pin 5a, and the end of pin 5a and a ring 5c are connected as a single entity, the other end is hinged with catch 5b.Catch 5b is rotated and pin 5a formation angle, can prevent that locking pin 5 from withdrawing from, coming off from baffle plate 1; Through locking pin 5 is set below pulley 2, can guarantee can not to turn on one's side or come off when this restorer is installed on the overhead ground wire.

Baffle plate 1 is partly interconnected with a slice vertical plate by a slice transverse slat part and constitutes " T " sub-shape, and the lacing hole 1a on the baffle plate 1 is positioned at the bottom of its vertical plate part, and the position that two vertical plates partly are positioned at above the lacing hole 1a also is coated with a locking pin 5.Baffle plate 1 adopts T shape structure, and the insulation pull rope is fastened on the lacing hole 1a of T-shape baffle plate 1 bottom during use, in distraction procedure, can make this restorer stressed more even, on ground wire, slides more steady.

Pulley 2 is loaded on the pulley spindle 3, and the both ends of pulley spindle 3 have screw thread, and the transverse slat part that a baffle plate 1 is passed at the two ends of pulley spindle 3 respectively connects with a nut 4.So promptly can realize the installation of pulley 2 between two baffle plates 1, can realize two connections between the baffle plate 1 again.

Visible by Fig. 1, after setting this restorer on the overhead ground wire 6, pass lacing hole 1a with insulation pull rope 8, pull insulation pull rope 8 these restorers of traction on ground and on overhead ground wire 6, move, push stockbridge damper 7 through this restorer, it is resetted.
