Abstract
The invention discloses a spring hook capable of making a 500KV electric power circuit short-circuit ground wire solve the problem that the traditional wire clip difficultly hangs the wire and cannot directly hang a drainage wire on an inner angle side of an angle tower. On the basis of the conventional wire clip for a short-circuit ground wire, the spring hook is arranged to make the wire clip positioned in a pull-back hook state, and the drawing force of a person replaces impact of gravity, so that an operator pulls the wire clip upwards to easily hang the short-circuit ground wire. The spring hook is a hook riveted on a sleeve, the sleeve is coiled and fixed on a short-circuit wire a certain distance away from the wire clip, the other end of the hook is connected with a spring, the spring is fixed on the short-circuit wire through a bracket, and a fixing clip for hanging the spring is arranged on the rear of the wire clip.
Description
Affiliated technical field
The present invention relates to the short-circuit grounding wire of 500kv power circuit, especially can make it overcome the spring grab that the conventional wires wire clamp is carried additionally difficulty and can not directly be carried additionally the drainage thread of angle tower interior angle side.
Background technology
At present, existing short-circuit grounding wire is made up of wire clamp, earth connection, earth terminal chuck etc.During line maintenance, for the electricity that prevents to misdeliver, other branch road send electricity or induced voltage just must carry additionally short-circuit grounding wire to the injury of the person or equipment.But, be to utilize the self gravitation of wire clamp to impact the support tongue piece in the wire clamp downwards and make it to break away from the elastic force that supports retracting spring to clamp lead in the design of traditional earth connection.Because long, the thick own wt of earth connection is much larger than the weight of wire clamp, not enough to lower punch power, support tongue piece in the wire clamp and can not break away from support, the interference of wind-force often makes wire clamp dehisce can accurately not aim at lead, also has the drainage thread of angle tower interior angle side owing to can't carry additionally not below cross-arm.
Summary of the invention
For overcome that existing earth connection carrys additionally that difficulty, wind-force are disturbed and the drainage thread of angle tower interior angle side not horizontal but below the deficiency that can not carry additionally, the invention provides a kind of spring grab, this grab is installed on the existing earth connection, can realize simple, as the to change pine drainage thread of carrying additionally tangent tower lead and angle tower interior angle side, not disturbed by wind-force, avoid Danger Electric shock risk.
The technical solution adopted for the present invention to solve the technical problems is: increase a spring grab and wire clamp is in pull back the hook-type state on the basis of existing short-circuit grounding wire wire clamp, replace the impulse force of gravity by people's pulling force, upwards spur wire clamp by operating personnel like this and just can carry additionally short-circuit grounding wire easily.The spring grab is one, and sleeve pipe is fixed on the short-circuit line of wire clamp certain distance by the grab of rivet clasp on sleeve pipe, and the other end of grab is connected with spring, and spring is fixed on the short-circuit line by a carriage.When adding hanging earthing conductor, earlier wire clamp is turned round turnback, the fixed card that an end of spring is hung on the wire clamp rear portion nails on, and extension spring makes grab hook the duckbilled open top end of wire clamp, and opening has just made progress like this.Then, wire clamp is placed the lead below, be pulled upwardly, the support chip in the wire clamp takes off a wire clamp and clamps lead, carrys additionally success.During dismounting, secondary pulling ground wire comes off the spring grab, and the wire clamp opening turns to the below, spurs earth connection once more, and wire clamp comes off.In order to guarantee effectively to carry additionally, the pulling force of spring must be suitably greater than the maximum release force that supports tongue piece in the wire clamp.
The invention has the beneficial effects as follows: carry additionally simple to operate, quick and can carry additionally not horizontal but below the drainage thread of angle tower interior angle side, be not subjected to the interference of wind-force, avoid Danger Electric shock risk.Adopt rivet clasp grab and spring on sleeve pipe.Simple in structure, copper coin material the best.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

Fig. 6 is the course of action figure of this spring grab.
1. existing wire clamps among the figure, 2. wire clamp tongue piece, 3. ground connection annealed copper wire, 4. earth terminal folder, 5. sleeve pipe, 6. spring, 7. spring trustship, 8. bail, 9. grab, 10. rivet, 11. wire clamps, 12. insulator strings, 13. leads, 14. iron towers horizontal but.
Embodiment
In Fig. 2,3 illustrated embodiments, sleeve pipe (5) and grab (9) rivet (10) rivet clasp, sleeve pipe (5) volume is solid on earth connection (3), and spring trustship (7) volume is solid on earth connection (3), and spring (6) penetrates spring carrier (7) and is connected with grab (9).
Operating procedure: when adding hanging earthing conductor, ground connection annealed copper wire (3) is turned back, spring (6) hangs on the bail (8), and pulling spring (6) makes grab (9) be hooked in wire clamp (11) duckbilled top, forms as shown in Figure 2 the opening state that makes progress.If lead (13), places wire clamp (11) lead (13) below as shown in Figure 4 in cross-arm (14) below, upwards socket ground wire (3) lead (13) and enter wire clamp (11) and wire clamp tongue piece (2) is dashed, wire clamp (11) is clamped lead (13).If lead (13) not in cross-arm (14) below, is thrown wire clamp (11) as shown in Figure 5 hang on the lead (13), the earth connection of pulling back (3) action is the same.This just overcomes the deficiency of existing wire clamp shown in Figure 1 (1).Dismounting is during earth connection, as shown in Figure 6, secondary pulling earth connection (3), grab (9) comes off, and spring (6) comes off from bail (8) immediately, and wire clamp (11) transfers that Open Side Down to, spurs earth connection (3) once more, and wire clamp (11) comes off.
Claims (3)
1. a spring grab installs a spring grab additional on existing short-circuit grounding wire, in wire clamp one side a bail is set, and it is characterized in that: the opening that will have the wire clamp of short-circuit grounding wire by the spring grab now makes progress by transferring to downwards.
2. according to claim 1, it is characterized in that: the wire clamp opening by returning back to upwards and a side of opening being fixed on the earth connection, is formed " hook " shape downwards, realize the pulling-back type operation.
3. spring grab according to claim 1 is characterized in that: spring links to each other with grab and is fixed on the earth connection by a carriage, and the grab rivet clasp is on sleeve pipe, and the sleeve pipe volume is solid on earth connection.
