Description

Manipulator for live fastening bolts of power transmission line diversion plate

technical field

The invention relates to an improvement of a bolt loading and unloading tool for a drain plate, in particular to a live tightening bolt for a drain plate of a power transmission line that can realize simultaneous forward and reverse rotation of a screw rod and a nut, fast installation and fastening or quick disassembly, and convenient operation. solid manipulator.

Background technique

The diversion plate is a part connected by the drainage wire, the hanging wire string, and the parallel ditch clamp in the transmission line. The diversion plate is made of two rectangular aluminum plates and then passed through the corresponding through holes on the two plates through the screw and fixed with a nut. , A ring gasket and an elastic gasket are set on the screw rod. In order to be more difficult to loosen, sometimes two nuts are set on the upper end of the screw rod. After a period of operation of this kind of diversion plate, the contact resistance of the diversion plate and the parallel groove clamp will become larger due to factors such as the loosening of the screw and the nut and the oxidation of the contact surface. When the current load passing through is relatively large, the parallel groove The temperature of the local area on the contact surface of the wire clamp rises, and then redness, metal melting, etc. occur. In severe cases, the jumper wire may be burnt and cause an accident. Tighten to ensure the safe operation of the line.

At present, most of the tools used in live work are insulating wrenches and insulating sleeves. Each operation requires two insulating wrenches or insulating sleeves. One clamps the screw seat to prevent the screw from rotating, and the other clamps the nut. Turn clockwise to tighten the nut relative to the screw, but this tool needs to intermittently and continuously change the position of the clamping nut and pull it back and forth, so the tightening speed is slow, labor-intensive and inefficient; if the same drainage There are two groups of bolts arranged side by side on the board, and when an insulating wrench or an insulating sleeve tightens one group of bolts, the other group of bolts will hinder the turning handle and affect the operation.

It can be known by searching that in order to improve the deficiencies of the above prior art, there are many reports about the bolt fastening tool for the drainage plate, such as Chinese patent CN104242149A discloses a "bolt tightener for the drainage plate of the strain tower", which includes an insulating rod, a rotating shaft , Sleeve wrench, through the sleeve wrench and nut butt joint rotation; CN203019274U discloses a kind of "strain tower drainage joint plate screw fastening wrench", including sleeve rod, pull rod, puller, rotating shaft, and a ratchet is added on the rotating shaft , There is a rack on the upper end of the pull rod, and the continuous one-way rotation of the trigger is realized through the ratchet. However, this improvement still requires intermittent and continuous reciprocating pulls, which does not significantly increase the fastening speed and reduce labor intensity; at the same time, due to the addition of an insulating operating rod, the operating distance is extended and the safety performance is improved. This eliminates the difficulty of quickly aligning the socket with the nut and tires the eyes. There are also reports of motor-driven hexagonal screw barrels. Although the fastening speed has been improved, the problem of the screw being fixed and not rotating has not been solved. At the same time, other accessories must be equipped, which is not easy to operate. Have not yet seen the report that can realize the simultaneous forward and reverse rotation of the two ends of the drainage plate screw, fast fastening special tool.
