Abstract

The present invention relates to a lead screw type trigger. The structure of the lead screw type trigger is that a square tube sleeves on the outer surface of a lead screw, a movable shaft is arranged above the square tube and is equipped with a trigger ring, and the two ends of the movable shaft are connected with one ends of a pull plate I and a pull plate II respectively; a connecting shaft is arranged between the other ends of the pull plate I and the pull plate II, and is connected with the trigger; the trigger is clamped on the trigger ring via a clamping structure, and the pull plate I and the pull plate II are located outside the trigger ring. According to the present invention, the lead screw is utilized to drive the trigger, so that the work personnel do not need to pull open a bowstring manually, and accordingly, the working efficiency and range of the on-site work are improved, and the labor intensity of the work personnel is relieved.

Description

Screw rod type trigger
Technical field
The present invention relates to a kind of trigger, the screw rod type trigger that particularly operation is used on transmission line, belongs to electric power conveying technology field.
Background technology
In power system operation and maintenance live line working process, transmission line is maked somebody a mere figurehead lead wire and earth wire, often there will be disconnected strand fracture of wire, need maintainer to repair and overhaul, under operation field environment and conditions permit, need tower shooting rope on operating personnel, if operation field environment and condition do not allow, just need to throw and hang insulation ropes at operation field manpower, if 15 meters of following can manpower throwing extensions, if surpass 15 meters, just need specific purpose tool to hang insulation ropes, on setting wire, there is no insulation ropes, will cancel current accident maintenance, cause repairing work normally to carry out.Throwing and hanging insulation ropes instrument is the string of manually pulling the bow with the trigger using conventionally, and range is short, and labour intensity is large.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of screw rod type trigger is provided, in solution prior art, throw extension insulation ropes range short, the problem that labour intensity is large.
Technical scheme of the present invention is as follows:
The outer surface suit square tube of leading screw, the top of square tube is provided with movable axis, movable axis is provided with trigger ring, the two ends of movable axis connect respectively one end of arm-tie I and arm-tie II, between the other end of arm-tie I and arm-tie II, be provided with connecting axle, on connecting axle, connect trigger, on trigger, by clamping structure, be stuck on trigger ring; Arm-tie I and arm-tie II are positioned at the outside of trigger ring.
Described leading screw is by the fixing movable axis of nut.
Described trigger ring is right angle U-shaped.
Described leading screw, movable axis and trigger ring are mutually vertical.
Described arm-tie I and arm-tie II are obliquely installed, and arm-tie I and arm-tie II and trigger ring form angle.
Described clamping structure is saw dental structure.
Tool of the present invention has the following advantages:
Utilize leading screw band trigger action, do not need operating personnel manually to pull open bowstring, improve operating efficiency and the range of field operation, alleviated operating personnel's labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side structure schematic diagram of Fig. 1.
In figure, 1, leading screw, 2, connecting axle, 3, arm-tie I, 4, trigger, 5, movable axis, 6, trigger ring, 7, saw tooth, 8, nut.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the present invention in detail.
Embodiment
As shown in Figure 1-2, the outer surface of leading screw 1 suit square tube, the top of square tube is provided with movable axis 5, and leading screw passes through fixedly movable axis of nut 8, and movable axis is provided with right angle U-shaped trigger ring 6, and leading screw, movable axis and trigger ring are mutually vertical; The two ends of movable axis connect respectively one end of arm-tie I 3 and arm-tie II, between arm-tie I and the other end of arm-tie II, are provided with connecting axle 2, connect trigger 4 on connecting axle, saw tooth 7 clamping structures be stuck on trigger ring on trigger by opening; Arm-tie I and arm-tie II are positioned at the outside of trigger ring; Described arm-tie I and arm-tie II are obliquely installed, and arm-tie I and arm-tie II and trigger ring form angle.
During use, on trigger ring, hang up steel wire rope string, utilize leading screw band trigger action ring, make the whole steel wire rope string that drives of trigger, reach maximum pull, penetrate insulation ropes and hang on aerial conducting wire.
The above is specific embodiments of the invention and the know-why used, and any equivalent transformation based on technical solution of the present invention basis, within all belonging to protection scope of the present invention.
