Description
Technical field
The utility model relates to a kind of electric pole installation auxiliary device, relates in particular a kind of double end wire tensioning device.
Background technology
Electric pole all needs to draw two bracing wires after installing, and bracing wire and electric pole form triangle, thereby can utilize the fastness of the principle increase electric pole that triangle steadiness is good; Bracing wire is generally to imbed earth anchor at reservation point when mounted, then the steel cable being connected with earth anchor is joined together to form to bracing wire with the steel cable being connected with electric pole upper end, and in order to strengthen the firm counterbalance effect of bracing wire, needs two steel cable tensions, make it exceptionally straight, after stringing, could strain electric pole like this, play well firm effect, steel cable connection is in the past to adopt artificial stringing mostly, by manpower, strain, stringing is not only wasted time and energy like this, and stringing weak effect, accident-proneness.
Utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of double end wire tensioning device is provided, and wastes time and energy, the problem of stringing weak effect while having solved pole guy stringing in the past.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: double end wire tensioning device, the wiring fixture of two same structures that comprise sleeve and be connected with sleeve, described sleeve is provided with internal thread through hole, and described two wiring fixtures are threaded in respectively sleeve two ends.This programme is when application, the steel cable that connection of two wiring fixtures is connected with earth anchor, another connects the steel cable being connected with electric pole, after connecting, sleeve is threaded with two wiring fixtures, pass through rotational sleeve, by being threaded of sleeve and wiring fixture, two wiring fixtures can screw in to inside along internal thread hole, thereby band is automatically connected in the steel cable tension at binding clip tool two ends, after being tightened to necessary requirement, utilize and connect steel part by two bracing wires connection tensions, after connection, take off again this device; This programme is simple in structure, can realize easily and efficiently stringing, and without the operation of many people stringing, stringing is effective, practical simultaneously.
Described wiring fixture comprises clamp head and the external screw thread joint pin being connected with clamp head, and external screw thread joint pin is connected with internal thread through hole threaded engagement.The external screw thread joint pin of wiring fixture is realized axial stretching motion for being connected with sleeve, and clamp head is used for bracing wire to clamp, and the two has coordinated stringing jointly.
Described clamp head cross section is concave shape, comprise two side plates that are parallel to each other and the connecting plate being connected with two side plates, cavity between described two side plates is clamp chamber, clamp is provided with hold-down screw in chamber, two side plates are run through at hold-down screw two ends, and described connecting plate outside connects external screw thread joint pin.Clamp head, when connecting stay wire, is placed in the annulus of bracing wire junction in clamp chamber, and fixes by hold-down screw, bracing wire can be clamped.
Described connecting plate and external screw thread joint pin junction are provided with limited step.For preventing sleeve and joint pin excessive screwing damaged screw, so limited step is set, can limit the degree of screwing of sleeve and joint pin.
Described hold-down screw end is connected with retainer ring.While taking off clamp head after using, due to bracing wire tension, hold-down screw stressed being difficult for takes off, and now can in retainer ring, insert straight-bar, by rotating straight-bar, screws out screw, thereby knockout screw very easily reduces dismounting difficulty.
Described sleeve outside also connects handle.Sleeve is when rotating stringing, and staff can hold handle rotational sleeve, convenient use.
Described sleeve is also being provided with ratchet with handle junction.Because sleeve is when rotating, the sleeve handle that turns around also needs to rotate a circle, and staff is very inconvenience when rotational sleeve, and waste time and energy, so sleeve is being established ratchet with handle junction, staff's rotational sleeve among a small circle just when rotational sleeve, easy to use.
Described grip surface is provided with hatching knurling.Grip surface is established the frictional force that hatching knurling can be strengthened handle and hand, anti-skidding.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is simple in structure, and stringing is effective, practical.
It is time saving and energy saving, easy to loading and unloading when 2, the utility model is used.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
Embodiment 1
Double end wire tensioning device as shown in Figure 1, comprises sleeve 2 and the wiring fixture 1 of two same structures being connected with sleeve 2, and described sleeve 2 is provided with internal thread through hole, and described two wiring fixtures 1 are threaded in respectively sleeve 2 two ends.
In the present embodiment, two wiring fixtures 1 are in clamping connection bracing wire, and rotational sleeve 2 drives wiring fixture to screw in to sleeve 2 is inner, thereby tension two ends bracing wire realizes stringing, and simple in structure, easy to use, stringing is effective.Wiring fixture 1 in the present embodiment can be that the fixture of buckle structure, the fixture of the fixture of clamping pin structure, hook formation or the fixture of circulus all can as long as can clamp bracing wire.
As preferably, described wiring fixture 1 comprises clamp head 4 and the external screw thread joint pin 9 being connected with clamp head 4, and external screw thread joint pin 9 is connected with internal thread through hole threaded engagement.The external screw thread joint pin 9 of wiring fixture 1 is realized axial stretching motion for being connected with sleeve 2, and clamp head 4 is for bracing wire is clamped, and the two has coordinated stringing jointly.
