Background technology
Power transmission tower frame is requisite bracing or strutting arrangement in transmission line of electricity, and its stability has vital effect for whole transmission system.Chinese utility model patent CN 203096780U and CN201232194Y individually discloses two kinds of different pylon structures, improves the fastening devices bottom it, improves the stability of pylon.But out of doors in environment for use, the main stress point of pylon is at its top, and cable can drive insulator string to produce and rock, thus is passed to pylon itself.Known by lever principle, this structure of only carrying out reinforcing in bottom cannot bear larger moment.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti-offset assembly of power transmission tower frame, can solve the deficiencies in the prior art, improves pylon to the buffering of rocking transmitted by cable.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of anti-offset assembly of power transmission tower frame, comprise tower body, tower body top is symmetrically arranged with several insulator strings, described tower body internal symmetry is provided with two supports and a base, base is provided with holddown groove, support is articulated with in holddown groove, insulator string is arranged on two supports respectively, chute is provided with inside support, slide between two chutes and be provided with cross bar, the two ends of cross bar are provided with the spring body be connected in chute, the inwall of holddown groove is provided with rubber layer, the mid portion of rubber layer is provided with depressed part, the both sides of depressed part are provided with jut, metallic struts is provided with in jut, the both sides of holddown groove are also provided with triangle fixed mount, be provided with terminal pad below base, be provided with link between base and terminal pad, link comprises central post, is provided with annular projection in the middle part of central post, is staggeredly equipped with several the first reinforcing ribs between the two ends of central post and annular projection.
As preferably, described terminal pad top is fixedly connected with tower body, and be provided with threaded column bottom terminal pad, tower body is provided with thread bush, threaded column is socketed in thread bush.
As preferably, described tower body is positioned at part above terminal pad and the part be positioned at below terminal pad is respectively arranged with independently the second reinforcing rib.
The beneficial effect adopting technique scheme to bring is: the utility model is provided with support at the top of pylon, when cable be subject to external force produce rock time, cable drives support to move up and down, when side support-moving, opposite side support can produce rightabout movement under the drive of cross bar, and this will offset the amplitude that both sides cable rocks.When support moves in holddown groove, support and rubber layer produce Relative friction, produce inhibitory action to the mobile of support.The jut of rubber layer both sides can increase the frictional force to support, and inner metallic struts achieves the linear increase of support frictional force along with the increase of open angle.Whole pylon be divide into two independently parts by terminal pad, the twisting resistance that base absorbs is passed to terminal pad by central post, by terminal pad, twisting resistance is converted into the extruding force of vertical direction, thus avoid sliding for producing bottom pylon or reversing, improve whole pylon and resist the ability of rocking.First reinforcing rib can strengthen the intensity of central post.On pylon, two independently the second reinforcing ribs, can ensure that pylon can not produce the twisting of globality.
