A support frame comprises two supports which are symmetrically arranged at the open end of an insulation cup, each support is hinged to the insulation cup, a connecting piece is arranged on the middle upper portions of the two supports and located on a plane intersected with the plane where the two supports are located, the supports and the connecting piece can swing together around the hinged joint of the two supports, two positioning protrusions in vertical distribution are arranged on the upper portions of the two supports respectively, the positioning protrusions and the connecting piece are positioned on two sides of the plane of the supports respectively, and the distance between the outer surfaces of the positioning protrusions is equal to or smaller than that between two support frames of one overhead line fault indicator. The supports with the positioning protrusions are added on the insulation cup of an existing fault indicator installation tool, so that a V-shaped clamping groove and a pull pin can be accurately positioned and forced to return accurately, returning of the pull pin is facilitated, and further installation success rate of the fault indicators is increased.
Description
Technical field
The present invention relates to a kind of erecting tools, particularly a kind of fault indicator for overhead lines Electrified installation tool.
Background technology
A considerable amount of fault detectors have been installed in the built on stilts 10kV circuit of distribution by a lot of offices at present, the structure of fault detector be comprise be positioned at bottom for holding the bottle of various electronic devices and components and standing on the bracing frame of two ear shapes on bottle, be provided with through hole on bracing frame top, in through hole, be provided with the pin that draws that runs through two bracing frames, draw a termination of pin that positioning cap is set, draw pin from the through hole of a bracing frame through hole through another bracing frame, drawing drawing between the positioning cap of pin and first bracing frame on pin rod, to be provided with extension spring, between two bracing frames, be provided with V-type draw-in groove, the both sides of described V-type draw-in groove are provided with and may be stuck in the slideway sliding on bracing frame, below V-type draw-in groove, be provided with pretensioned spring, described Compress Spring one end is connected to the bottom of V-type draw-in groove, the other end of spring is fixed on the bottle of fault detector.This fault detector is in the time of work, first the pin that draws of fault detector to be pulled out, pull-out draw pin should be withdrawn in first through hole supporting can not all to pull out again, pretensioned spring resilience like this, utilize V-type draw-in groove to block and draw pin, in the time installing, this fault indicator for overhead lines is put into fault detector erecting tools, existing fault detector erecting tools, be by one insulation goblet and be connected in insulation goblet bottom insulating bar form, using, fault detector is put into insulation cup, to draw pin pull-out, then utilize insulating bar, with this fault detector, it is firmly impacted to line cord, utilize impulsive force that thereby the Compress Spring in fault detector is pressed down to discharge and draw pin, now draw pin return under the effect of self extension spring restoring force, thereby make to draw pin return to be worn on the through hole of getting back to another bracing frame.But actual situation is, due to reasons such as manufacturing process: the center of departing from V-type draw-in groove such as Compress Spring, or bracing frame run-off the straight will not cause drawing pin return to be made mistakes in situations such as upright states, make to draw pin cannot pass another bracing frame, so just cause fault detector not correctly to be installed on cable, the damage of dropping, the event of even pounding the personnel of work happens occasionally.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of erecting tools that improves the fault indicator for overhead lines that is mounted to power is provided.
A kind of erecting tools of fault indicator for overhead lines, include insulation cup, bottom at insulation cup is provided with the coupling arrangement being connected with insulating bar, its structural feature is: described aerial conductor fault indicator also comprises bracing frame, described bracing frame include be arranged on insulation cup openend be symmetrically arranged with two stands, two stands is hinged on respectively on insulation cup, the middle and upper part of two stands is provided with a connection piece, this web member in the plane of the Plane intersects at two stands place on, the related web member of two stands can swing around the pin joint of two stands, be respectively arranged with the locating convex block of vertical distribution on the top of two stands, two locating convex blocks and web member divide the both sides in two stands place plane, the distance of two locating convex block outside surfaces is equal to or less than the distance between fault detector two bracing frames, locating convex block two stands during in erectility by the extruding downwards of the V-type draw-in groove of fault detector and will draw pin to withstand on one of them support.
The erecting tools of the fault indicator for overhead lines of this structure, in the time that needs carry out fault detector installation, two stands is rotated, then pack fault detector into, the V-type draw-in groove of fault detector is pressed down, then rotating two stands makes it in vertical position, make the lower end of locating convex block prop up V-type draw-in groove and stop its return, then will draw again pin to pull out in a conventional way, be rotated further support, the locating convex block of erecting tools is propped up and draw pin, then this fault detector is sent into cable end or wire is installed, when the V-type draw-in groove of this fault detector touches after cable, continuing upwards to push erecting tools makes the web member on erecting tools touch cable extruded cable head or wire, there is downward return swing in the extruding that is subject to cable end or wire due to web member, occur to drive whole support to rotate around pin joint to the web member of lower swing, thereby drive locating convex block to be swung away from V-type draw-in groove and to draw pin place, the positioning action that so just makes to draw pin and V-type draw-in groove not to be subject to locating convex block and return, thereby fault detector is hung on safely on cable.
Described web member is C type or shaped as frame.
The weight that adopts the web member of this structure can greatly fall light whole erecting tools can play equally again the effect of installation, can greatly save the production cost of this instrument.
Described C type or the web member of shaped as frame are a member structure.
Described support is a kind of truss-frame structure.
Adopt truss-frame structure can greatly alleviate weight and the production cost of erecting tools.
Described truss-frame structure is a kind of truss-frame structure of plane formula.
Adopt the truss-frame structure of plane formula, can greatly alleviate the weight of support.
The coupling arrangement being connected with insulating bar is connected on insulation cup by universal joint, and coupling arrangement is arranged on universal joint.
The described coupling arrangement being connected with insulating bar or for castellated coupling arrangement, or be screw connection.
In sum, the present invention's following advantage compared to existing technology:
Installation tool for overhead line fault indicator of the present invention, owing to having added the support with locating convex block on the insulation cup at existing fault detector erecting tools, therefore can and draw pin accurately to locate and impel their accurate returns V-type draw-in groove, thereby conveniently draw the return of pin, thereby the power that is mounted to that greatly improves fault detector, success ratio reaches 100%.
