Description
Technical field
The utility model relates to Maintenance of Electric Transmission Line technical field of tools, specifically a kind of one-way ratchet wrench.
Background technology
At present, the 500kV circuit overwhelming majority is overhead transmission line, is vulnerable to the impact of the environmental factors such as wind, rain, ice and snow in running, causes appearance displacement, the even fatigue damages such as conductor spacer.In order to process in time displacement and the damage problem that 500kV line segregation rod exists of repairing, line upkeep operating personnel need to operate with conductor spacer propeller, and tradition is generally two-way for rotating the angle of rake ratchet spanner of conductor spacer, and it is heavier to conduct oneself with dignity, and size is larger, operate more complicated, not Portable belt and use, easily cause operating personnel's physical fatigue, inefficiency, is unfavorable for completing in the short period of time the maintenance work to 500kV circuit.
Utility model content
For addressing the above problem, it is a kind of simple to operate that the utility model provides, conduct oneself with dignity lighter, compact conformation, portable a kind of novel one-way ratchet wrench, described one-way ratchet wrench is specially adapted for operating interval rod propeller, can reduce line upkeep staff's working strength, and improve its operating efficiency.
For achieving the above object, the technical scheme that the utility model is taked is as follows: a kind of one-way ratchet wrench, comprises interior mesh ratchet gear, spring, ratchet, trepanning parts, lower cover, upper cover, rivet, handle; Handle one end is fixedly connected with interior mesh ratchet gear outer, the inner trepanning parts of placing of interior mesh ratchet gear, centered by trepanning parts, opening square hole has the cylinder of otch on one side, square hole center is corresponding to the center of circle of interior mesh ratchet gear, otch outer is flexibly connected the ratchet that can make ratchet one-way rotate, the ratchet other end is resisted against in the teeth groove of interior mesh ratchet gear, between ratchet is near one end of teeth groove and trepanning parts, spring is set; The diameter of described lower cover and upper cover is between the external diameter and internal diameter of interior mesh ratchet gear, lower cover is placed under interior mesh ratchet gear, upper cover is placed on interior mesh ratchet gear, upper cover is fixedly connected with rivet with trepanning parts with lower cover, and position and the consistent size of the position of lower cover and upper cover center drilling and size and trepanning parts center drilling.
As a kind of improvement: the square that the center drilling of described trepanning parts is 13mm * 13mm.
Described one-way ratchet wrench entire length is 160mm, and thickness is 8mm.
Compared with prior art, the utility model has the advantages that: the utility model adopts single direction ratchet design, has reduced Wrench head weight, parts as a whole, more common reversible ratcheting tool has saved separated grinding tool hole parts, and more compact structure operates simpler and easy; Trepanning adopts special-purpose positive square design, can better coordinate more convenient operation with traditional conductor spacer propeller; Entire length is reduced to 2/3 of common reversible ratcheting tool, and weight is reduced to 1/3 of common reversible ratcheting tool, carries and more convenient operation.In a word, the utility model is more suitable for operating interval rod propeller, can reduce line upkeep staff's working strength, and improve its operating efficiency.
Accompanying drawing explanation
Fig. 1 is the modular construction schematic diagram of one-way ratchet wrench.
Fig. 2 is that one-way ratchet wrench trepanning parts are installed to the top view after interior mesh ratchet gear.
Fig. 3 is the lateral plan after one-way ratchet wrench is installed.
In figure: mesh ratchet gear in 1-; 2-spring; 3-ratchet; 4-trepanning parts; 5-lower cover; 6-upper cover; 7-rivet; 8-handle.
The specific embodiment
By reference to the accompanying drawings, a kind of one-way ratchet wrench: comprise interior mesh ratchet gear 1, spring 2, ratchet 3, trepanning parts 4, lower cover 5, upper cover 6, rivet 7, handle 8; Described handle 8 one end are fixedly connected with interior mesh ratchet gear 1 outer, the inner trepanning parts 4 of placing of interior mesh ratchet gear 1, centered by trepanning parts 4, opening square hole has the cylinder of otch on one side, square hole center is corresponding to the center of circle of interior mesh ratchet gear 1, otch outer is flexibly connected the ratchet 3 that can make ratchet one-way rotate, ratchet 3 other ends are resisted against in the teeth groove of interior mesh ratchet gear 1, between ratchet 3 is near one end of teeth groove and trepanning parts 4, spring 2 are set; The diameter of described lower cover 5 and upper cover 6 is between the external diameter and internal diameter of interior mesh ratchet gear 1, lower cover 5 is placed under interior mesh ratchet gear 1, upper cover 6 is placed on interior mesh ratchet gear 1, upper cover 6 is fixedly connected with trepanning parts 4 use rivets 7 with lower cover 5, and position and the consistent size of the position of lower cover 5 and upper cover 6 center drillings and size and trepanning parts 4 center drillings.
The center drilling of described trepanning parts is the square of 13mm * 13mm.
Described one-way ratchet wrench entire length is 160mm, and thickness is 8mm, adopts cast steel, guarantees spanner mechanical strength.The about 50g of the whole deadweight of spanner.
The operation of this specific embodiment is as follows, while needing to advance securing member, as shown in Figure 2, clockwise direction swing handle 8, now, ratchet 3 is resisted against in the teeth groove of interior mesh ratchet gear 1, makes trepanning parts 4 overlap securing member and and then turns over certain angle, another mistake clockwise swing handle 8, now, spring 2 compressions, ratchet 3 slips at hook tooth back, trepanning parts 4 transfixions.When handle 8 is made continuous reciprocally swinging, securing member is and then done unidirectional intermittent movement.In the time of need stepping back securing member, only need upset one-way ratchet wrench, with another side, operate.
The utility model is simple to operate, can reduce line upkeep staff's working strength, and improves its operating efficiency.
