Abstract
The utility model relates to a kind of screw rod type trigger, its structure is, 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, and the two ends of movable axis connect respectively one end of arm-tie I and arm-tie II, between arm-tie I and the other end of arm-tie II, is provided with connecting axle, on connecting axle, connect trigger, on trigger, be stuck on trigger ring by clamping structure; Arm-tie I and arm-tie II are positioned at the outside of trigger ring.The utility model utilizes leading screw band trigger action, does not need operating personnel manually to pull open bowstring, improves operating efficiency and the range of field operation, has alleviated operating personnel's labour intensity.
Description
Technical field
The utility model relates to a kind of trigger, and 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, just need specific purpose tool to hang insulation ropes if exceed 15 meters, 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.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of screw rod type trigger, throws extension insulation ropes range short, the problem that labour intensity is large in solution prior art.
The technical solution of the utility model 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, be stuck on trigger ring by clamping structure; Arm-tie I and arm-tie II are positioned at the outside of trigger ring.
Described leading screw is fixed movable axis by 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.
The utlity model has following advantage:
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.

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 utility model in detail.
Embodiment
As shown in Figure 1-2, the outer surface suit square tube of leading screw 1, the top of square tube is provided with movable axis 5, and leading screw is by the fixing 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.
When use, on trigger ring, hang up steel wire rope string, utilize leading screw band trigger action ring, make trigger entirety drive steel wire rope string, reach maximum pull, penetrate insulation ropes and hang on aerial conducting wire.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on technical solutions of the utility model basis, within all belonging to protection range of the present utility model.
