Fixture for preventing from pulling out in bracing wire of the present utility model, comprise that more than one tension unit has the tension assembly of hollow structure and is arranged at the drag-line connector on tension assembly with detachable being fixedly connected to form, described tension assembly cross section is wedge structure;
Further, described tension unit is frame structure, and described tension module outer surface is provided with covering;
Further, described tension unit comprises upper support that parallel longitudinal arranges and the end wall bracket of lower support and the fixing upper support of oblique support and lower support, along the end of described upper support and lower support, is vertically arranged with support fixed head;
Further, described upper support, lower support, end wall bracket are angle steel;
Further, between described upper support and lower support, be vertically arranged with reinforcement, the two ends of described reinforcement are welded and fixed with upper and lower bracing frame respectively;
Further, described support fixed head is provided with the wing plate that lays respectively at support and lower support outer surface;
Further, described tension unit is 4, and described tension unit is fixedly connected with by joint bolt;
Further, described covering is steel plate;
Further, described drag-line connector is U-shaped structure.
The beneficial effects of the utility model: the interim stringing tensile device of power line of the present utility model, the bracing wire during for line maintenance is installed, and own wt is light, but globality is strong, stabilized structure, tensile strength is high, there is feature safe, light, easy transportation, when discharging labour, increase work efficiency, accelerate job schedule, have again simple in structure simultaneously, easily processing, the features such as cost is low, can also be combined into different size specifications, highly versatile as required.It is convenient to reclaim in addition, has also saved construction cost, and then saves Financial cost; Solved in ultra-high-tension power transmission line construction, a difficult problem of setting up temporary guy, has not only improved operating efficiency but also ensured construction safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model; As shown in the figure: the fixture for preventing from pulling out in bracing wire of the present embodiment, comprise that more than one tension unit 1 has the tension assembly 2 of hollow structure and is arranged at the drag-line connector on tension assembly 2 with detachable being fixedly connected to form, described tension assembly 2 cross sections are wedge structure; By tension unit, be assembled into the tension assembly 2 with hollow structure, can alleviate the own wt for the installing mechanism of bracing wire, be convenient to transportation, be also convenient to handling, alleviate operator's labour intensity, also improve the fail safe of operation.In addition, adopt detachable fixing to need Optional assembling according to scene, meet the user demand of different condition, be also convenient to installation and removal, and then be convenient to reclaim.
In the present embodiment, described tension unit 1 is frame structure; The tension assembly 2 of its formation is also frame structure; Described tension assembly 2 outer surfaces are provided with covering; Be covering by the framework setting that is coated and fixed, the structure that adopts framework to add covering reaches and alleviating deadweight and can meet high-tensile demand again simultaneously, also saves in addition material, and then saves Financial cost.
