Abstract
The invention relates to an electrical installation tool, namely a strain-resistant tower drainage plate bolt tightener. The strain-resistant tower drainage plate bolt tightener is characterized in that a long and thin insulating rod (1) is arranged, a connecting rod (4) is hinged to the front end of the insulating rod (1) through a rotary shaft (3), the other end of the connecting rod (4) is fixedly connected with a socket wrench (5), and the socket wrench (5) is matched with an end cap of a drainage plate bolt and a nut. The strain-resistant tower drainage plate bolt tightener has the advantages that a maintainer can complete the drainage plate bolt tightening operation by holding the insulating rod by hand, buckling the socket wrench to the end of the drainage plate bolt and then pushing and pulling the insulating rod, so that high risk operation such as climbing and hanging is avoided, safety is achieved, labor is saved, and hot line work can be carried out. The strain-resistant tower drainage plate bolt tightener has the advantages of being simple in structure, low in manufacturing cost, convenient to carry and operate, low in requirement for operation conditions and the like and is expected to become a necessary tool in the industry.
Description
Technical field
The present invention relates to a kind of power ampere holding tool, i.e. a kind of strain tower drainage plate bolt tightener.
Background technology
The drainage thread of 220kV strain tower is connected with main line by drainage plate and bolt.Can cause loosening of bolt because circuit waves, initiation drainage plate is crossed thermal ablation and is even come off.For this reason, line rule regulation: all will carry out fastening to strain tower drainage plate bolt when line maintenance.The fastening method taked at present is equal potential working method mainly, and operating personnel climbs insulated flexible ladder and enters highfield suspention or hint operation, and waste time and energy, risk is high, to the technical ability of personnel and requirement for environmental conditions very harsh.And wire had both been subject to downward pulling force in personnel's climbing process, can amplitude of fluctuation be strengthened again, overheated or when being about to come off at drainage plate, more easily rupture, thus cause human casualty accident.
Summary of the invention
The object of this invention is to provide one and can avoid equal potential working, operating personnel need not climb rope ladder, also need not suspend in midair or hint operation, can carry out fastening to drainage plate bolt, and strain tower drainage plate bolt tightener that is safe, laborsaving, convenient and efficient.
Above-mentioned purpose is realized by following technical scheme: develop a kind of strain tower drainage plate bolt tightener, be characterized in: have the insulating bar that elongated, front end to be hinged a connecting rod by rotating shaft, connecting rod another end is connected mutually with socket wrench, and end cap and the nut of socket wrench and described drainage plate bolt match.
One section of tabular joint is installed in described insulating bar front end, and joint front end is provided with axle sleeve, and axle sleeve is connected with described axis of rotation, and the another end of rotating shaft and the axle sleeve of connecting rod one end are rotationally connected.
The invention has the beneficial effects as follows: the hand-held insulating bar of maintainer, socket wrench is buckled in drainage plate bolt end, push-and-pull insulating bar can complete the terminal operation of drainage plate bolt, thus avoid the high-risk operations such as climbing suspention, safety labor-saving, and structure simple, cheap, be easy to carry, convenient operation, less demanding to operating condition, be expected to become the indispensable instrument of industry.
Accompanying drawing explanation
Fig. 1 is a kind of front view of embodiment;
Fig. 2 is the left view of this embodiment;
Fig. 3 is the working state schematic representation of this embodiment;
Fig. 4 is the another kind of working state schematic representation of this embodiment.
Visible in figure: insulating bar 1, joint 2, rotating shaft 3, connecting rod 4, socket wrench 5, axle sleeve 6.
Embodiment
The total design of the present invention is by the spanner with stock, carries out the terminal operation of strain tower drainage screw at a distance.Only exemplify an embodiment below:
Embodiment: as shown in Figure 1 and Figure 2, this strain tower drainage plate bolt tightener has an elongated insulating bar 1, insulating bar 1 front end to be hinged a connecting rod 4 by rotating shaft, and connecting rod 4 another end is connected mutually with socket wrench 5, and end cap and the nut of socket wrench 5 and drainage plate bolt match.
For the insulating bar 1 that intensity is lower, the tabular joint 2 of one section of high-strength material can be installed in its front end, and joint 2 front end is provided with axle sleeve 6, and axle sleeve 6 and described rotating shaft 3 are rotationally connected, and the another end of rotating shaft 3 and the axle sleeve 6 of connecting rod 4 one end are rotationally connected.
During work, operating personnel can as shown in Figure 3, stand on the cross-arm of shaft tower, stretched out by insulating bar 1, the socket wrench 5 of front end is stuck in be needed on fastening nut, then, push-and-pull insulating bar 1, drivening rod 4 and socket wrench 5 rotate around bolt-center, and nut can be made to compress.
In order to prevent screws, as shown in Figure 4, can adopt two fasteners, one side blocks the end cap of bolt, and another side blocks the nut of bolt, relative reverse rotation, can complete terminal operation.
Winter in 2013, temperature is below-25 DEG C, belong to the weather conditions forbidding that equipotential operates, experimenter adopts this fastener, line is won at the tooth in the Inner Mongol, prick skein and implement the operation of 220kV earth potential live for twice, the workload of original one week is completed by 4 hours, successfully carry out the terminal operation of drainage plate bolt completely, decrease Bock figure, the loss of outage in the area such as Zhalantun, ensure the safe and stable operation of circuit, create considerable economic benefit, and significantly alleviate labour intensity, improve live-working safety coefficient, decrease the injury of highfield to human body, be subject to the high evaluation of test block.
Claims (2)
