The utility model relates to a kind of protective device, particularly relates to a kind of live line working and prevents wire dropping backup protection equipment.It is by following Structure composing: with bail two pieces of main boards respectively by the fixed lever of upper end adapting position and connecting rod and rear portion win in succession and the fixed axis of bail connects and composes main hook part, be located at the U-shaped hook in the middle of two pieces of main boards, its afterbody adapting position is fixed with spring; This spring other end is connected with connecting rod, and U-shaped hook is connected with main hook part by the fixed axis through its front end through hole, is fixed on the locking pin on winning in succession and the groove match being located at out U-shaped hook rear portion.The utility model is simple and reasonable for structure, lightweight, easy to carry, swift to operate, save the activity duration, simplify operational method, improve operating efficiency, reliably prevent the potential safety hazard that wire comes off suddenly to personnel and equipment generation, and it is with low cost, long service life, brings great convenience to user.
Description
Technical field
The utility model relates to a kind of protective device, particularly relates to a kind of live line working and prevents wire dropping backup protection equipment.
Background technology
In " electric power safety working regulation ", regulation " is changed the operation of straight path insulator string and movable conducting wire, when adopting simple catenary device, should be taked the backup protection measure preventing wire dropping ".The wire dropping backup protection measure that prevents adopted in the live line working of 66-500 KV transmission line has: 1, use " double-U-shaped protection hook ".Passed from two U-shaped centres by wire during use, reverse protection hook and make wire enter U-shaped end thus hook wire, the other end plays a protective role cross-arm side is locked.Adopt the method side of wire not have locking device, when wire does not have stressed, protection hook loosens easily to deviate from from wire; 2, use insulating cord one end to pinion wire, add task difficulty, the other end plays a protective role cross-arm side is locked.Use the method operating personnel that equipotential method must be taked to install; when live line working does not need to adopt equipotential method operation; and during in order to prevent wire dropping from adopting the method to carry out backup protection; live line working method has carried out again unnecessary increase; personnel and safety measure etc. have also carried out unnecessary increase accordingly; make live line working become complicated like this, personnel and equipment easily produce potential safety hazard, also reduce operating efficiency simultaneously.
Summary of the invention
The utility model is for above-mentioned Problems existing; a kind of protective device with blocking function is provided; operating personnel just can be installed easily and fast at earth potential, reliably prevent the backup protection equipment of wire dropping, to solve the problems that existing safeguard measure is brought.
The purpose of this utility model realizes by the following technical solutions:
Live line working prevents wire dropping backup protection equipment, by following Structure composing: with bail two pieces of main boards respectively by the fixed lever of upper end adapting position and connecting rod and rear portion win in succession and the fixed axis of bail connects and composes main hook part, be located at the U-shaped hook in the middle of two pieces of main boards, its afterbody adapting position is fixed with spring; This spring other end is connected with connecting rod, and U-shaped hook is connected with main hook part by the fixed axis through its front end through hole, is fixed on the locking pin on winning in succession and the groove match being located at out U-shaped hook rear portion.
Described U-shaped hook also can be substituted by notched loop-hook.
Described spring is extension spring.
The utility model compared with prior art has following advantageous effect: the utility model is simple and reasonable for structure, lightweight, easy to carry, swift to operate, save the activity duration, simplify operational method, improve operating efficiency, reliably prevents wire to come off suddenly the potential safety hazard produced personnel and equipment.Again because using the metal material of high strength to make, thus continuous operation or unexpected stressed time can not deform, solve many potential safety hazards that existing safeguard measure is brought, and with low cost, long service life, brings great convenience to user.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is left TV structure schematic diagram of the present utility model;
Fig. 3 is A-A sectional structure schematic diagram of the present utility model.
In figure: fixed lever 1, connecting rod 2, U-shaped hook 3, fixed axis 4, spring 5, locking pin 6, main board 7, high-strength insulating rope 8, wins 9 in succession.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail; but protection range of the present utility model not limited by specific embodiment; be as the criterion with claims; in addition; with without prejudice under the prerequisite of technical solutions of the utility model, any change that the those of ordinary skill in the art made the utility model easily realize or change can fall within right of the present utility model.
Embodiment 1
Live line working as shown in Figure 1, Figure 2 and Figure 3 prevents wire dropping backup protection equipment, by following Structure composing: with bail two pieces of main boards 7 respectively by the fixed lever 1 of upper end adapting position and connecting rod 2 and rear portion win in succession 9 and the fixed axis 4 of bail connect and compose main hook part, fixed lever 1 and connecting rod 2 adopt the bolt of stock to make, be located at the U-shaped hook 3 in the middle of two pieces of main boards 7, its afterbody adapting position is fixed with extension spring 5; This extension spring 5 other end is connected with connecting rod 2, and U-shaped hook 3 is connected with main hook part by through the fixed axis 4 of its front end through hole, by being screwed on win in succession locking pin 6 on 9 and the groove match being located at out U-shaped hook 3 rear portion.
Embodiment 2
Live line working prevents wire dropping backup protection equipment, by following Structure composing: with bail two pieces of main boards 7 respectively by the fixed lever 1 of upper end adapting position and connecting rod 2 and rear portion win in succession 9 and the fixed axis 4 of bail connect and compose main hook part, fixed lever 1 and connecting rod 2 adopt the bolt of stock to make, be located at the notched loop-hook 3 in the middle of two pieces of main boards 7, its afterbody adapting position is fixed with extension spring 5; This extension spring 5 other end is connected with connecting rod 2, and notched loop-hook 3 is connected with main hook part by through the fixed axis 4 of its front end through hole, by being screwed on win in succession locking pin 6 on 9 and the groove match being located at out loop-hook 3 rear portion jaggy.
During concrete use:
First high-strength insulating rope 8 is first connected on fixed lever 1 by operating personnel; Then operating personnel to make a movement locking pin 6 with hand-screw; locking pin 6 is thrown off in the groove at U-shaped hook 3 rear portion; and after driving U-shaped hook 3 to open mode; new for this practicality shape protective device high-strength insulating rope 8 is put to wire place; wire is made to enter in the opening hook of U-shaped hook 3; lift high-strength insulating rope 8; U-shaped hook 3 can reach closure state automatically by wire pressure; U-shaped hook 3 is made to reach closure state; locked in the groove that now locking pin 6 enters U-shaped hook 3 rear portion, now spring is in extended state.
