Description
Technical field
The invention belongs to electric power maintenance equipment, particularly a kind of new tool be used to the various model insulator connecting pins of choosing.
Background technology
In recent years, along with the increase year by year of Hangzhou grid power workload demand, new line every year, steel tower quantity was increasing with the speed increment of up to a hundred kilometers.(the thundering) complicated and changeable of weather, intricate (high mountain, the area with more lightning activities) of landform, make the probability that transmission line is struck by lightning be the trend increased year by year, also corresponding increasing of the quantity of revealing occurs in the glass porcelain vase thereupon, and old circuit also needs maintenance, therefore, change thunderbolt, damaged, aging insulator is hundreds of.In order not affect the normal operation of transmission line, just must change at short notice faulty insulator.Usually, adopt pin pulling clamp to extract connecting pin, then damaged insulator is changed.Traditional pin pulling clamp as shown in Figure 1, comprises by stock 101 and quarter butt 102 and forms " L " type main body, is provided with coupler body 104 in quarter butt 102 ends, is provided with a pair of balancing pole 102 in intersection 105 both sides of stock 101 and quarter butt 102.During use, the free end 106 of hand-held stock 101, the coupler body 104 of quarter butt 102 ends is inserted in the collar extension of connecting pin, intersection 105 is placed on the porcelain vase of insulator as fulcrum, press down the free end 106 of stock 101, drive coupler body 104 and upwarp, thereby connecting pin is extracted in bulb, upper and lower insulator is thrown off.The pin pulling clamp of this structure has following defect:
1, connecting pin commonly used has R type and two kinds of structures of W type.Figure 2 shows that the structure of R type connecting pin, it comprises a collar extension 61.The coupler body of pin pulling clamp 104 is inserted into to the collar extension 61 of connecting pin is interior can extract connecting pin.Therefore, traditional pin pulling clamp can be used in and extracts R type connecting pin.Yet for W type connecting pin, referring to Fig. 2, this W type connecting pin comprises the opening 82 at two collar extensions 81 in left and right and a middle part.All at sidepiece, and connecting pin is ductile due to two collar extensions 81, therefore can't extract.Even firmly it is extracted, also can cause the permanent deformation of connecting pin and can't reuse.Therefore operating personnel must prepare standby pin and just can change new insulator, and this can't realize while operating in the wild.
2,, for H anti-fouling type large distance insulator, because coupler body 104 can't be deep into the connecting pin position, therefore also can't operate.
3, because effect fulcrum in operating process is fixed on same position, easily cause the porcelain vase explosion and local stress is concentrated, bring accident to service work.
4, when operation, a pair of balancing pole 102 is also very easily encountered intact porcelain vase, and collision easily causes porcelain vase to break.
Summary of the invention
The present invention will solve is the problems referred to above that prior art exists, aim to provide a kind of simple in structure, practicality and high efficiency, easy to operate, use safety, the new tool of the various model insulator connecting pins that are applicable to choose.
For addressing the above problem, the present invention is by the following technical solutions: a kind of pin removal be used to all types of insulator connecting pins of choosing, the connecting rod that comprises main part, described connecting rod front end is provided with the semi-circular hook of pulling pin, rod rear end is provided with the platypelloid type shovel of pulling pin, and the described platypelloid type shovel of pulling pin is 145 degree ± 10 degree angles with described connecting rod and arranges; The described hook of pulling pin comprises the semi-circular part and the extension be connected with described semi-circular part end be connected with described connecting rod, and described extension is vertical with the plane of the described shovel of pulling pin; The described shovel end of pulling pin is W type notch design; Described connecting rod bottom surface is " V " type structure of indent, and the breakover point of described " V " profile is near the described shovel of pulling pin.
The invention has the beneficial effects as follows:
1, because the two ends that connect are respectively equipped with pull pin hook and the shovel of pulling pin, the described hook of pulling pin can act on R type connecting pin, and the described shovel of pulling pin can act on W type connecting pin, while making the present invention use, can not be subject to the restriction of insulator model.The line maintenance personnel use this instrument, can realize the replacing to various model insulators on 35kV-500kV strain insulator and straight line pole, have improved the efficiency of power transmission lines overhauling work, reduce the activity duration on maintainer's bar, thereby reduce work high above the ground danger.Particularly, due to the light practicality of instrument of the present invention, easy and simple to handle, safe and reliable, will establish solid foundation for applying of its.
2, in the process of hook was pulled pin in use, the position of the fulcrum of active force produced continuous displacement with the rotation of coupler body, is displaced downwardly to porcelain vase from the steel cap of insulator, and when fulcrum was transferred to porcelain vase, connecting pin just in time was pulled out.Therefore, porcelain vase stressed less, and the time is very short, can not cause explosion.
3,, because the present invention is simple and compact for structure, when operation, can not collide porcelain vase, thereby can not cause the accident of porcelain vase to crash through.
4, the platypelloid type shovel of pulling pin is 145 degree ± 10 degree angles with connecting rod and arranges, and the shovel that makes to pull pin on the one hand can enter into the enterprising line operate in connecting pin position smoothly, and active force can effectively be delivered on connecting pin, can reduce again on the other hand the moment loss in transmittance process.
5, the described hook of pulling pin comprises the semi-circular part and the extension be connected with described semi-circular part end be connected with described connecting rod.Described extension pulls pin with described that to even face out vertical.This extension can be deep into the interior steel cap of H anti-fouling type large distance glass tempering insulator and the junction of bulb, and R type connecting pin is extracted.
6, the described shovel end of pulling pin is W type notch design, or tack or semi-circular design, and the former is optimum structure, can carry out good coordinating with W type connecting pin when horizontal sliding, has effectively protected the integrality of connecting pin.W type connecting pin after extracting is reusable, thereby the insulator that can will newly change within the shortest time is fixed to corresponding position.
7, described connecting rod bottom surface is " V " type structure of indent, and the breakover point of described " V " profile is near the described shovel of pulling pin.Should " V " profile transfer function power effectively, and can improve the intensity of connection, make it in operating process not frangibility.
As a modification of the present invention, connecting rod is long strip type, and with the described hook of pulling pin, is integral formula casting with the shovel of pulling pin and is connected.This structure, the bulk strength of product is high, is conducive to the transmission of active force.
