Background

The technology of crossing and sealing the net of the power transmission line is mature, two supporting ropes are connected by using crossing frame bodies on two sides of a crossing object, then insulating ropes and insulating rods are coated on the supporting ropes by using net pulling ropes, and finally the crossing and sealing net is formed above the crossing object, so that the crossing object is protected when a lead ground wire is spread. After the ground wire is completely unfolded, the insulating rope and the insulating rod are retracted through the net pulling rope (changed into a net retracting rope), and finally the bearing rope is removed.

However, the net pulling wire is divided into two types:

the one is through, namely, one whole is used, two operators are connected with the insulating rope and the insulating rod in a fastening mode during construction, continuous unfolding is achieved, and the trafficability characteristic (namely, when the vehicle passes through) is good. There are problems: the size of each operator buckle is not fixed, so that the size of the net sealing is not standard, which is secondary, and the key is that the tightness of the two supporting ropes is inconsistent, and finally, the net sealing device cannot be continuously unfolded or cannot be recycled.

The other one is that the net pulling rope is connected by a plurality of fixed-length spacing ropes with O-shaped locks, which solves the problem of different tightness of the bearing rope, but also has new problems: the net can not cross the coaster in succession when receiving the net, must take off the O type lock one by one and retrieve, whole process all can only be that high altitude construction personnel accomplish alone moreover, if span length is great, block net when big cause easily because of phenomenon such as tired out of hand, can lead to a series of hidden troubles to appear.

Thus, the exemplary terms "at 8230; \8230; above" may include both orientations "at 8230; \8230; above" and "at 8230; \8230; below". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a stride across special R type anchor clamps of block net hauling rope, includes left splint 1 and right splint 2, the middle part of left side splint and right splint is articulated through hinge 3, is equipped with the spring on the hinge, based on high altitude personnel construction convenience, and has fine operation continuity, adopts spring structure, also decides according to general people's grip, can change and can use repeatedly. The front end of the left clamping plate is a semicircular clamping groove 4, the front end of the right clamping plate corresponding to the front end of the left clamping plate is provided with vertical teeth 5, and the vertical teeth are arranged at four positions. Four vertical teeth are arranged on the plane side, so that the rope can be bitten without damaging the rope, and the friction force is increased, so that the rope can be effectively fixed on the net pulling rope. The rear end of the right splint is provided with a connecting hole 6. The design of the connecting hole takes into account that the hand is not affected by the connecting hole during operation, and the connecting hole can be well connected with an OX type (or XX type) universal rotary connecting ring. The front end of the right splint bends outwards to form two bending parts 7, and the vertical teeth are arranged at two ends of the bending parts. The bending part extends into the opening of the semicircular clamping groove. The shape of the invention is similar to that of an iron clamp, the net pulling rope is clamped or removed by utilizing the elasticity of a spring, one surface of an R-shaped clamp is provided with an arc to facilitate the embedding of the net pulling rope, the other surface of the R-shaped clamp is provided with four vertical teeth to prevent slipping caused by insufficient holding power, and the net pulling rope can be firmly held; a round hole is punched at the end of the handle, so that the handle is conveniently connected with an insulating rope and an insulating rod. Before construction, marks are made on the hauling cable according to the distance positions, the R-shaped clamp is connected with the insulating rope and the insulating rod through an OX-type (or XX-type) universal rotary connecting ring, and during construction, high-altitude operation personnel only need to clamp the R-shaped clamp on the hauling cable marking positions in sequence, and the hauling cable is tightened by the other side, so that the laying task is finally completed.
