The utility model content
The purpose of this utility model provides a kind of simple in structure, convenient and practical OPGW releasing pulley anti-hopping device.
This novel purpose is achieved in that a kind of groove-jumping preventing device of cable communication line releasing pulley, mainly is made up of structure identical last nylon wheel and following nylon wheel; Wherein, last nylon wheel structure is: the nylon wheel body is arranged on the nylon wheel shaft rotationally, and nylon wheel shaft two ends are connected with nut; The shape of upper left fixed head and upper right fixed head is " L " font, and the nylon wheel shaft of last nylon wheel is fixed between upper left fixed head and the upper right fixed head, and the nylon wheel body is with a gap between upper left fixed head and bottom right fixed head; The nylon wheel shaft of following nylon wheel is fixed between lower-left fixed head and the bottom right fixed head, and the nylon wheel body of following nylon wheel is with a gap between lower-left fixed head and bottom right fixed head; Be provided with T type bolt between upper left fixed head and the lower-left fixed head: the horizon bar portion of T type bolt is hinged on the upper left fixed head, and the nut of T type bolt is positioned at its vertical bar subordinate end; Structure has been uniformly set another T type bolt between upper right fixed head and the bottom right fixed head, and is equipped with the opening that inserts for T type bolt bottom on lower-left fixed head and the bottom right fixed head.
The above-mentioned nylon wheel shaft of going up nylon wheel is provided with copper sheathing.
Above-mentioned outer end of going up the nylon wheel shaft of nylon wheel is provided with spring pin.
The horizon bar portion of above-mentioned T type bolt and the articulated structure of upper left fixed head are: the overhanging end middle part of upper left fixed head has an opening, opening two ends to curl into two cylindrical shells, and the horizon bar portion two ends of T type bolt are stretched into respectively in these two cylindrical shells versatilely.
Above-mentioned upper left fixed head, the lower-left fixed head all is welded with stiffener on upper right fixed head and the bottom right fixed head.
This novel advantage is: simple in structure, convenient and practical, effectively avoiding critical raises up tower position OPGW job-hopping and scrapes mutually with the releasing pulley metal parts and to cause damage, avoid handling the loaded down with trivial details of job-hopping, make OPGW exhibition knock off to do more smooth and easy and guaranteed quality, reduce construction cost, had good application prospects.

Embodiment
Fig. 2, Fig. 3 illustrate, this novel mainly by identical the last nylon wheel of structure and following nylon wheel (among Fig. 1 retractable cable take turns 13 and the two is tangent) form; Wherein, last nylon wheel structure is: nylon wheel body 1 is arranged on the nylon wheel shaft 2 rotationally, and nylon wheel shaft two ends are connected with nut 4; The shape of upper left fixed head 6 and upper right fixed head 7 is " L " font, and the nylon wheel shaft 2 of last nylon wheel is fixed between upper left fixed head and the upper right fixed head, and nylon wheel body 1 is with a gap between upper left fixed head and bottom right fixed head; The nylon wheel shaft of following nylon wheel is fixed between lower-left fixed head 8 and the bottom right fixed head 9, and the nylon wheel body of following nylon wheel is with a gap between lower-left fixed head and bottom right fixed head; The horizon bar portion that is provided with T type bolt 10:T type bolt between upper left fixed head 6 and the lower-left fixed head 8 is hinged on the upper left fixed head 6, and the nut of T type bolt is positioned at its vertical bar subordinate end; Structure has been uniformly set another T type bolt between upper right fixed head 7 and the bottom right fixed head 9, and is equipped with the opening that inserts for T type bolt bottom on lower-left fixed head 8 and the bottom right fixed head 9.The nylon wheel shaft 2 of last nylon wheel is provided with copper sheathing 3.The outer end of the nylon wheel shaft 2 of last nylon wheel is provided with spring pin 5.
Referring to Fig. 4, the horizon bar portion of T type bolt and the articulated structure of upper left fixed head are: the overhanging end middle part of upper left fixed head 6 has an opening, opening two ends to curl into two cylindrical shells, and the horizon bar portion two ends of T type bolt 10 are stretched into respectively in these two cylindrical shells versatilely.Upper left fixed head 6, lower-left fixed head 8 all is welded with stiffener 11 on upper right fixed head 7 and the bottom right fixed head 9.
The structure of upper left fixed head and upper right fixed head is identical, and the two all is " L " font, is bent by bar shaped sheet material to form, and there is a hole end, long limit, is used for fixing wheel body.Two cylindrical shells are curled into after cutting a part in the minor face end, and the bolted splice of T type is on these two cylindrical shells.
