Abstract
The invention discloses a support of an overhead transmission line used for letting down ground wires and optical cables, characterized by comprising a vertical support, inclined supports in connection with the vertical support, and a distance piece connected to the top end of the vertical support; the other end of the distance piece is provided with a suspension ring; the lower part of the vertical support is provided with a neck used for being clamped to an iron tower bolt. The support is provided with the vertical support, the distance piece and the inclined supports, is an auxiliary support apparatus used for letting down ground wires and optical cables of an electric transmission line with a voltage higher than 500 kV, and solves the problem that for original ground wires or optical cables, the joint space between original ground wire or optical cable hardware fittings and an iron tower is small, the amplitude of tightening ground wires after a tackle is suspended is small, and work personnel can not tighten the ground wires, dismount accessories or let down the ground wires.
Description
Technical field
The present invention relates to support when a kind of overhead transmission line let-down ground wire, optical cable, it is applicable to more than 500kV ultra-high-tension power transmission line overhead ground wire, the installation of the process of the optical cable line of fall and gold utensil annex changes.
Background technology
In 500kV earth wire of power transmission line, optical cable service work, often need to fall ground wire, optical cable, complete service work on ground.During line of fall operation, coaster need be hung at earth wire support place, utilize mill rope to mention ground wire, transfer again after ground wire suspension clamp of dismantling.Due to ground wire hanging position tower material of iron tower and ground wire, hypotelorism between optical cable, insufficient space, mill rope is made to mention ground wire or optical cable amplitude is too small, even to hang after coaster coaster bottom lower than ground wire or optical cable suspension height ineffective by coaster, the dismounting realizing ground wire or optical fiber cable fitting cannot be completed, for addressing this problem in work before this, often with bundling thick waddy as interim heightening bracket, strengthen the distance between steel tower suspension coaster and ground wire, although this way solves the earth wire support problem short with ground linear distance, but waddy fail safe is poor, more inconveniently to carry, thus reduce the operating efficiency of operating personnel, increase labour intensity.
Summary of the invention
The technical problem to be solved in the present invention is to provide support when a kind of structure simple, easy to use and overhead transmission line let-down ground wire, optical cable that fail safe is high.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: support when a kind of overhead transmission line let-down ground wire, optical cable, its key technology is: it comprises vertical supporting, the bearing diagonal be connected with described vertical supporting and the horizontal support being connected to vertical supporting top, the described horizontal support other end is provided with suspension ring, and described vertical supporting bottom is provided with the draw-in groove for being stuck on steel tower bolt.
Described vertical supporting is the angle steel of two pieces of back-to-back vertical settings, described bearing diagonal arranges 2, respectively arranges one in the both sides of vertical supporting, and one end of described bearing diagonal is connected with the top of vertical supporting, the other end is provided with the claw for being arranged on steel tower, and described claw is provided with jackscrew.
Described bearing diagonal is angle steel, connects after two bearing diagonals install through attachment bolt.
Described horizontal support is angle steel, and described horizontal support is located between two angle steel of vertical supporting.
The beneficial effect adopting technique scheme to produce is:
The present invention is provided with vertical supporting, horizontal support and bearing diagonal, it is for auxiliary support apparatus when high pressure 500kV above transmission line let-down ground wire, optical cable, change original because of ground wire or optical cable due to gold utensil and optical cable or ground wire and space, steel tower junction little, the amplitude of ground wire can be tightened up too small after pulley suspension, operating personnel cannot tighten up ground wire, removes a difficult problem for annex and let-down ground wire.And the present invention is the design of triangle rock-steady structure, and each parts are bolted, and have the features such as lightweight, size is little, material is firm, in use, be easy to carry, fail safe is high, by changing parts, is applicable to all kinds of turriform.500kV and above overhead transmission line ground wire, optical cable service work can be widely used in.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1, horizontal support, 2, suspension ring, 3, vertical supporting, 4, attachment bolt, 5, claw, 6, jackscrew, 7, bearing diagonal, 8, draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in more detail.
See accompanying drawing 1, the bearing diagonal 7 the present invention includes vertical supporting 3, being bolted with described vertical supporting 3 and bolt are connected to the horizontal support 1 on vertical supporting 3 top, described horizontal support 1 other end is hung with suspension ring 2, and described vertical supporting bottom is provided with the draw-in groove 8 for being stuck on steel tower bolt.
Described vertical supporting 3 is the angle steel of two pieces of back-to-back vertical settings, described bearing diagonal 7 arranges 2, one is respectively arranged in the both sides of vertical supporting 3, one end of described bearing diagonal 7 is connected with the top of vertical supporting 3, the other end is provided with the claw 5 for being arranged on steel tower, and described claw 5 is provided with jackscrew 6.
Described bearing diagonal 7 comprises two angle steel, connects after two angle steel install through attachment bolt 4.Described horizontal support 1 is angle steel, and described horizontal support 1 is located between two angle steel of formation vertical supporting 3.
After adopting the present invention, on tower, the claw 5 of this support bearing diagonal 7 is fixed on steel tower by operating personnel in operation, the draw-in groove 8 of vertical supporting 3 is stuck on steel tower bolt, form stable triangle structure, be fixed on steel tower earth wire support, then coaster is hung on the suspension ring 2 of support, just can start unwrapping wire service work.
The present invention can be widely used in 500kV and above overhead transmission line ground wire, optical cable service work.
