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
Technical field
The present invention relates to a kind of trigger, the screw rod type trigger used particularly to operation on transmission line of electricity, belong to power transmission technical field.
Background technology
During Operation of Electric Systems with maintenance livewire work, transmission line of electricity makes somebody a mere figurehead lead wire and earth wire, disconnected stock fracture of wire often occurs, need maintainer to repair and overhaul, tower shooting rope on operating personnel is needed under work site environments and conditions permit, if work site environments and condition do not allow, it is accomplished by carrying out throwing at operation field manpower hanging insulation ropes, if can throwing with manpower and hang for less than 15 meters, if it exceeds 15 meters are accomplished by specific purpose tool and carry out hanging insulation ropes, insulation ropes is not had on setting wire, current accident maintenance will be cancelled, cause rushing to repair work cannot be normally carried out.Throwing and hanging the insulation ropes instrument trigger generally with use is string of manually pulling the bow, and range is short, and labor intensity is big.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, it is provided that a kind of screw rod type trigger, solve that prior art is thrown extension insulation ropes range short, the problem that labor intensity is big.
Technical scheme is as follows:
The outer surface suit square tube of leading screw, square tube be arranged over movable axis, movable axis is provided with trigger ring, the two ends of movable axis connect arm-tie I and one end of arm-tie II respectively, it is provided with connecting shaft between the other end of arm-tie I and arm-tie II, connect trigger in connecting shaft, trigger is stuck on trigger ring by clamping structure；Arm-tie I and arm-tie II is positioned at the outside of trigger ring.
Described leading screw fixes movable axis by nut.
Described trigger ring is right-angled U.
Described leading screw, movable axis and trigger ring are mutually perpendicular to.
Described arm-tie I and arm-tie II is obliquely installed, and arm-tie I and arm-tie II forms angle with trigger ring.
Described clamping structure is saw dental structure.
Present invention have the advantage that
Utilize leading screw band trigger action, it is not necessary to operating personnel manually pulls open bowstring, improve work efficiency and the range of field operation, alleviate the labor intensity of operating personnel.

Fig. 1 is the structural representation of the present invention.
Fig. 2 is the side structure schematic diagram of Fig. 1.
In figure, 1, leading screw, 2, connecting shaft, 3, arm-tie I, 4, trigger, 5, movable axis, 6, trigger ring, 7, saw tooth, 8, nut.
Detailed description of the invention
Referring to the drawings, in conjunction with specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1-2, the outer surface of leading screw 1 suit square tube, square tube be arranged over movable axis 5, leading screw fixes movable axis by nut 8, and movable axis is provided with right-angled U trigger ring 6, and leading screw, movable axis and trigger ring are mutually perpendicular to；The two ends of movable axis connect arm-tie I 3 and one end of arm-tie II respectively, are provided with connecting shaft 2 between the other end of arm-tie I and arm-tie II, and connecting shaft connects trigger 4, and trigger is stuck on trigger ring by opening saw tooth 7 clamping structure；Arm-tie I and arm-tie II is positioned at the outside of trigger ring；Described arm-tie I and arm-tie II is obliquely installed, and arm-tie I and arm-tie II forms angle with trigger ring.
During use, hanging up steel wire rope string on trigger ring, utilize leading screw band trigger action ring, make trigger entirety drive steel wire rope string, reach maximum pull, injection insulation ropes hangs on aerial conducting wire.
The above is the specific embodiment of the present invention and the know-why used, any based on the equivalent transformation on the basis of technical solution of the present invention, within belonging to protection scope of the present invention.
