Abstract

The improved rotation formula conductor spacer special spanner that the utility model provides, comprise handle and the strip pedestal with centre bore, also be provided with the screw rod being connected with handle 1, described screw rod is connected with base thread through centre bore, described pedestal is also provided with first and hangs pin and second and hang pin, described first one end and second of hanging pin hangs that one end of pin is hinged with the two ends of pedestal respectively, and first other end that hangs pin is provided with grab, and second other end that hangs pin is provided with snap ring; Also be provided with retainer ring, described retainer ring is flexibly connected with snap ring.The situation that when this spanner can solve conductor spacer installation, the latch of internal layer wire clamp cannot be fixing.The size of the retainer ring of this spanner bottom can regulate adding according to the wire diameter of wire man-hour, has certain scope of application; Simple in structure, easy to process, retainer ring adopts material station current material to machine.

Description

Improved rotation formula conductor spacer special spanner
Technical field
The utility model relates to electrical equipment technical field, concrete refers to a kind of improved rotation formula conductor spacer special spanner.
Background technology
Cable clip rotary type conductor spacer often uses in overhead transmission line, general producer is all furnished with special assembly wrench, but after the actual arrival of conductor spacer, often find that conductor spacer adds and has mismachining tolerance man-hour in producer, the special spanner of employing producer cannot normal mounting.
It is generally by using special spanner by the eyelet of the upper frame of conductor spacer, cover plate to be tightened up that conventional conductor spacer is installed, cover plate parcel wire clamp, wire clamp tightens up be fixed with latch afterwards completely, then latch on fixed outer layer cover plate, completes the fixing of conductor spacer.Because conductor spacer needs to carry out vibrationproof after installation, therefore the general rubber that adopts carries out vibrationproof on wire clamp, outer parcel galvanized part.The wire diameter that is suitable for of the general design of conductor spacer has certain scope; if when conductor spacer is used on the less wire of wire diameter; because the interlock of wire clamp is large not; also because adding, producer has certain error man-hour; often can meet when mounted outer cover plate and fit completely, the wire clamp of internal layer, due to the reason of wire diameter too small (or mismachining tolerance), can not overlap the eyelet on wire clamp completely; thereby the latch on wire clamp can not be passed, and impact is installed.
If adopt and pad aluminium armor tape (even if cover plate and wire clamp are held the diameter that increases internal layer while closing between cover plate and wire clamp, make the stressed increase of wire clamp, make eyelet overlap) mode, between that wire clamp and outer cover plate, with regard to gapless, after space bar installation, just can not play good antihunt action.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide one can carry out high-altitude installation very easily, facilitates the improved rotation formula conductor spacer special spanner of engineering construction.
For achieving the above object, the improved rotation formula conductor spacer special spanner that the utility model provides, comprise handle and the strip pedestal with centre bore, also be provided with the screw rod being connected with handle 1, described screw rod is connected with base thread through centre bore, it is characterized in that: described pedestal is also provided with first and hangs pin and second and hang pin, and it is hinged with the two ends of pedestal respectively that one end of pin is hung in described first one end and second of hanging pin, first other end that hangs pin is provided with grab, and second other end that hangs pin is provided with snap ring; Also be provided with retainer ring, described retainer ring is flexibly connected with snap ring.
As preferred version, on described grab, be also provided with projection.
Further, the length of described retainer ring is greater than first and hangs pin and the second spacing of hanging between pin.
The utility model has the advantage of: the situation that when this spanner can solve conductor spacer installation, the latch of internal layer wire clamp cannot be fixing.The size of the retainer ring of this spanner bottom can regulate adding according to the wire diameter of wire man-hour, has certain scope of application; Simple in structure, easy to process, retainer ring adopts material station current material to machine.
Brief description of the drawings
Working state schematic representation when Fig. 1 is the utility model installation wire clamp.
Fig. 2 is structural representation of the present utility model.
In figure: handle 1, pedestal 2, centre bore 2.1, the first hangs pin 2.2, grab 2.21, projection 2.22, the second is hung pin 2.3, snap ring 2.31, screw rod 3, retainer ring 4, wire clamp 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done further and described in detail.
Improved rotation formula conductor spacer special spanner as shown in the figure, comprise handle 1 and the strip pedestal 2 with centre bore 2.1, also be provided with the screw rod 3 being connected with handle 1, screw rod 3 is threaded with pedestal 2 through centre bore 2.1, pedestal 2 is also provided with first and hangs pin 2.2 and second and hang pin 2.3, it is hinged with the two ends of pedestal 2 respectively that one end of pin 2.3 is hung in first one end and second of hanging pin 2.2, and first other end that hangs pin 2.2 is provided with the other end that grab 2.21, the second hangs pin 2.3 and is provided with snap ring 2.31; Also be provided with retainer ring 4, retainer ring 4 is flexibly connected with snap ring 2.31.
On grab 2.21, be also provided with projection 2.22.The length of retainer ring 4 is greater than first and hangs pin 2.2 and the second spacing of hanging between pin 2.3.
Operation principle of the present utility model is as follows: the utility model is in conjunction with the special spanner of the existing producer supply of material, and wire clamp is installed separately.Wire clamp is column type, adopts the special spanner (spanner shank adopt be " L " shape round steel) of the producer supply of material to install wire clamp.Therefore special spanner shank is processed, " L " shape round steel of the shank of one side is processed into " b " type, and with material station existing retainer ring (PH type, the size of ring is advisable can just put next wire clamp after special spanner processing) be connected and fixed, retainer ring and spanner opposite side adopt L-type shank to tangle the movable connection method of the end of retainer ring, conveniently on wire, use and take out spanner.It is to make spanner increase lifting surface area when with wire clamp contact that special spanner bottom adopts the reason of retainer ring, prevents from skidding.As shown in Figure 1.
The pin of " L " type to special spanner lower end cuts, welding in the other direction and below increase a projection, make first to hang pin and form endways a recess, the convenient retainer ring of fixing in use.Second hangs pin adopts close ring, and the retainer ring of bottom side is fixed.
Because crossbeam between two legs of former special spanner is shorter, between two legs, spacing is less, and wire clamp cannot be inserted in, admittedly need increase in bottom a retainer ring, the spacing between two legs is strengthened.Bottom adopt retainer ring also can make wire clamp when mounted bottom be that plane is stressed, increase install time stability.Bottom adopts the fixing retainer ring of annulus, and while avoiding installing in high-altitude, retainer ring comes off.
Cable clip rotary type conductor spacer when mounted, is first installed inner side wire clamp, then outside gold utensil is installed.
The retainer ring that the utility model uses and the projection of increase are material station and gather materials on the spot, and weld.Processing is simple, and practicality, has saved processing cost.
