Description

The line hardware bolt tightener
Technical field
The utility model relates to a kind of tools for live working, relates in particular to a kind of line hardware bolt tightener.
Background technology
110KV~220KV power transmission network is being contacted directly operation of urban distribution network, and its power supply quality and power supply reliability are the key elements that electric company first will pay close attention to.Transmission system is in operation and often has the loosening phenomenon of metal bolt, such as the bolt of the gold utensils such as stockbridge damper, strain clamp, is an important content that improves the power transmission network safe operation to the hotline maintenance of 110KV~220KV power transmission network.Present Electrified fastening line hardware bolt in the circuit of 110KV~220KV power transmission network, normal operation be common wrench, the operating type that adopts all is equipotential, the preparation of Electrified fastening metal bolt just needs 30 minutes, the operating personnel needs 2 to 3 people on the bar, also must have 1 people to enter equipotential work, the engineering time approximately needs 2 to 3 hours.Adopt this maintenance mode, construction procedure is complicated, and difficulty of construction is large, and tool using is many, and coefficient of safety is low, and the activity duration is also longer.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model purpose is to provide a kind of tight sag of bolt that can make to reach specified standard, the job execution time is short, and coefficient of safety is high, can change the equipotential construction and be the line hardware bolt tightener of earth potential form of construction work.
The technical solution of the utility model is: a kind of line hardware bolt tightener, comprise a preset torque spanner and two telescopic insulating bars that are parallel to each other, the rear removable of described preset torque spanner connects an adapter sleeve, the top of the bottom of described adapter sleeve and an eradication edge action bars is hinged, another top of thoroughly doing away with the edge action bars is fixed with the U-shaped connector, have through hole on the described U-shaped connector, partial fixing at close its driving end of preset torque spanner has brace, described brace card is placed in the U-shaped connector, have installing hole on the brace, preset torque spanner by passing the U-shaped connector through hole and bolt and the U-shaped connector of the installing hole of brace be flexibly connected.
As preferably: described adapter sleeve top has adjustment hole, and the adjustment hole inwall is provided with internal thread, and adapter sleeve is provided with the bolt with adjustment hole internal thread coupling.
As preferably: the bottom of described insulating bar is provided with handle.
The beneficial effects of the utility model are: by preset torque spanner bottom installing insulating action bars, being provided with between preset torque spanner and insulating bar can be the two movable part that links together, preset torque spanner is connected with insulating bar to be connected, can remove easily again, thereby make the form of construction work of live line working change the earth potential operation into by the equipotential operation.When using the utility model to operate, preparation adds the activity duration only needs 15 to 20 minutes, and only need operation personnel, greatly shorten the live line working time, improved power supply reliability, reduced the workmen, simplified construction procedure, reduced construction labour intensity, improved the construction operation coefficient of safety, and can make the tight sag of bolt reach specified standard.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of A-A among Fig. 1;
Fig. 3 is the structural representation of B-B among Fig. 1.
Among the figure: 1, preset torque spanner; 2, insulating bar; 3, handle; 4, adapter sleeve; 5, bolt; 6, brace; 7, U-shaped connector.
Embodiment
As a kind of execution mode of the present utility model, as depicted in figs. 1 and 2, a kind of line hardware bolt tightener, comprise a preset torque spanner 1 and two telescopic insulating bars 2 that are parallel to each other, insulating bar 2 can optionally be regulated suitable length as required, the bottom of described insulating bar 2 is provided with handle 3, the rear removable of described preset torque spanner 1 connects an adapter sleeve 4, the top of the bottom of described adapter sleeve 4 and an eradication edge action bars 2 is hinged, another top of thoroughly doing away with edge action bars 2 is fixed with U-shaped connector 7, have through hole on the described U-shaped connector 7, partial fixing at preset torque spanner 1 close its driving end has brace 6, described brace 6 cards are placed in the U-shaped connector 7, have installing hole on the brace 6, preset torque spanner 1 by passing U-shaped connector 7 through hole and bolt and the U-shaped connector 7 of the installing hole of brace 6 be flexibly connected.
The utility model is by preset torque spanner 1 bottom installing insulating action bars 2, being provided with between preset torque spanner 1 and insulating bar 2 can be the two movable part that links together, preset torque spanner 1 is connected with insulating bar to be connected securely, can remove easily again, thereby make the form of construction work of live line working change the earth potential operation into by the equipotential operation.
When using the utility model to operate, preparation adds the activity duration only needs 15 to 20 minutes, and only need operation personnel, greatly shorten the live line working time, improved power supply reliability, reduced the workmen, simplified construction procedure, reduced construction labour intensity, improved the construction operation coefficient of safety, and can make the tight sag of bolt reach specified standard.
As shown in Figure 3, described adapter sleeve 4 tops have adjustment hole, and the adjustment hole inwall is provided with internal thread, and adapter sleeve 4 is provided with the bolt 5 with adjustment hole internal thread coupling.When needs change the direction of insulating bar 2, can withdraw from bolt 5, adjusting after the direction again, screwed in place bolt 5 makes adapter sleeve 4 relative fixing with preset torque spanner 1, can realize that so the staff in the direction adjustment of any angle to insulating bar 2, is not subjected to the restriction of job site.
