Abstract
The invention discloses a kind of new draw-in groove leading screw tension grip, it is characterised in that：Including clamp body, for the draw-in groove leading screw tension grip being connected to the first connector of the dead load tester and connects the second connector of the clamp body and first connector.Present invention efficiently solves draw-in groove leading screw cannot connect the problem that puts forth effort on dead load tester.
Description
【Technical field】
The present invention relates to power domain, more particularly to draw-in groove leading screw tension grip.
【Background technology】
Draw-in groove leading screw is mainly used in disconnecting for the insulator chain on line steel tower and more changes jobs, by the card of draw-in groove leading screw
Groove is stuck on the cross-arm on steel tower, and the other end is connected on the conductor wire end of insulator chain by arm-tie or pull-rod, by rocking arm control pine
Tightly the gravity of wire is afforded on leading screw to carry out more changing jobs for insulator chain, therefore the security performance of draw-in groove leading screw is necessary
Reliable.According to the rules, draw-in groove leading screw will do static load test, but the particularity due to draw-in groove shape, can be led using Bolted angle connection
Cause the fracture of non-rectilinear stress angle steel so that draw-in groove leading screw cannot be mounted directly on dead load tester and carry out stress test, because
And cause the static load of draw-in groove leading screw to test and cannot carry out.If the draw-in groove leading screw for not carrying out preventive trial is directly applied to
Construction, it will serious hidden danger is brought to the safety of electrical network, equipment and the employee for working in a line.
【Content of the invention】
For solving foregoing problems, the invention provides a kind of new draw-in groove leading screw tension grip, efficiently solves
Draw-in groove leading screw cannot connect the problem that puts forth effort on dead load tester.
In order to achieve the above object, the present invention is adopted the following technical scheme that：Draw-in groove leading screw tension grip, the draw-in groove
Leading screw tension grip is installed on dead load tester, it is characterised in that：Including being provided with the clamp body of accommodating chamber；For by institute
State the first connector that draw-in groove leading screw tension grip is connected to the dead load tester；And connect the clamp body and
Second connector of first connector；The accommodating chamber is provided with opening, and the opening is just to the dead load tester.
Further, second connector includes the vertical plate being vertically arranged and horizontally disposed horizontal plate, described perpendicular
Straight panel and the horizontal plate are in bar shaped, the vertical plate and the L-shaped connection of the horizontal plate.
Further, on the vertical plate, the clamp body is connected to the horizontal plate, institute to first connector
State opening to be located on the upside of the horizontal plate.
Further, reinforcement is provided between the vertical plate and the clamp body, the reinforcement is located at the fixture
The side of body.
Further, first connector is provided with installing hole.
After using above-mentioned technical proposal, the invention has the advantages that：Efficiently solve draw-in groove leading screw to try in static load
Test and the problem that puts forth effort on machine, cannot be connected, draw-in groove leading screw has been smoothly completed by the effectively connection of draw-in groove leading screw tension grip
Preventive trial hold tool gate of the quality monitoring, it is ensured that the safety of electrical network, equipment and front man, bring well to enterprise
Benefit.
The present invention these features and advantage will be detailed in following specific embodiment, accompanying drawing exposure.
【Description of the drawings】
The invention will be further described below in conjunction with the accompanying drawings：
