Description
Technical field
The utility model relates to a kind of safety wire bar draw-gear.
Background technology
Electric pole is used to install electric wiring, and electric wire, after laying completes, can produce a tractive force to electric pole, the tractive force therefore needing another one tractive force to carry out balance wires to produce.
In prior art, mostly adopt a cable wire and adjusting bracket to be used as the carrier of tractive force, but the security performance of this mode of traction is lower, when the thread failure of fixing tightwire, screw rod is deviate from adjusting bracket, causes solid failure, finally cause electric pole to tilt, cause electric power safety accident.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of safety wire bar draw-gear, and this device plays duplicate protection, effectively avoids traction to lose efficacy, avoids electric pole to tilt.
For solving the problem, the utility model adopts following technical scheme:
A kind of safety wire bar draw-gear, comprise rectangle adjusting bracket, described rectangle adjusting bracket upper, the medium position place of lower surface is provided with screwed hole, and threaded rod is combined with in described screwed hole, that one end that described threaded rod is positioned at described rectangle adjusting bracket outside is welded with draw ring, described in upper end, draw ring place is combined with overhead extension rope, described in lower end, draw ring place is combined with bottom traction rope, the outer circumference surface that described threaded rod is positioned at that one end of described rectangle adjusting bracket inside is provided with through hole, steel wire cable is combined with between the through hole of threaded rod described in two, the two ends of steel wire cable connect, joint location place is provided with fastening devices.
As preferred technical scheme, the middle section position place of described overhead extension rope is provided with collets, and described collets are glass brick.
As preferred technical scheme, four corner position place chamfered transition of described rectangle adjusting bracket.
As preferred technical scheme, described fastening devices comprises shell, and being arranged on the lock screw of described cover top portion, the joint of described steel wire cable is positioned at described enclosure, and described lock screw offsets with the joint location of described steel wire cable through after described shell.
The beneficial effects of the utility model are: this device is under routine use state, traction is completed by screw rod and rectangle adjusting bracket, when tractive force is excessive cause screw flight to lose efficacy time, carry out second traction by the steel wire cable connected between two screw rods, avoid two screw rods to be separated, this structure can effectively avoid electric pole to tilt, avoid the generation of electric power accident, the structure of this device is comparatively simple simultaneously, uses more for convenience, is applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of fastening devices.
Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult a kind of safety wire bar draw-gear shown in Fig. 1 and Fig. 2, comprise rectangle adjusting bracket 1, described rectangle adjusting bracket 1 upper, the medium position place of lower surface is provided with screwed hole (not shown), and threaded rod 2 is combined with in described screwed hole, that one end that described threaded rod 2 is positioned at described rectangle adjusting bracket 1 outside is welded with draw ring 201, described in upper end, draw ring 201 place is combined with overhead extension rope 3, described in lower end, draw ring 201 place is combined with bottom traction rope 4, the outer circumference surface that described threaded rod 2 is positioned at that one end of described rectangle adjusting bracket 1 inside is provided with through hole (not shown), steel wire cable 5 is combined with between the through hole of threaded rod 2 described in two, the two ends of steel wire cable 5 connect, joint location place is provided with fastening devices 6.
A preferred embodiment in the utility model, the middle section position place of described overhead extension rope 3 is provided with collets 333, and described collets 333 are glass brick.
A preferred embodiment in the utility model, four corner position place chamfered transition of described rectangle adjusting bracket 1.
A preferred embodiment in the utility model, described fastening devices 6 comprises shell 601, and be arranged on the lock screw 602 at described shell 601 top, the joint of described steel wire cable is positioned at described enclosure, and described lock screw offsets with the joint location of described steel wire cable through after described shell.
The beneficial effects of the utility model are: this device is under routine use state, traction is completed by screw rod and rectangle adjusting bracket, when tractive force is excessive cause screw flight to lose efficacy time, carry out second traction by the steel wire cable connected between two screw rods, avoid two screw rods to be separated, this structure can effectively avoid electric pole to tilt, avoid the generation of electric power accident, the structure of this device is comparatively simple simultaneously, uses more for convenience, is applicable to promoting the use of.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
