Description
Technical field
The utility model belongs to electric power maintenance equipment, particularly a kind of new tool of the various model insulator connecting pins that are used to choose.
Background technology
In recent years, along with the increase year by year of Hangzhou grid power workload demand, new line every year, iron tower quantity was increasing with up to a hundred kilometers speed increment.(the thundering) complicated and changeable of weather; Intricate (high mountain, the area with more lightning activities) of landform; The probability that transmission line is struck by lightning is the trend that increases year by year, and the glass porcelain vase takes place by also corresponding the increasing of quantity of self-destruction thereupon, and old circuit also needs maintenance; Therefore, change thunderbolt, damaged, aging insulator is hundreds of.In order not influence the normal operation of transmission line, just must change faulty insulator at short notice.Usually, adopt the pincers of pulling pin to extract connecting pin, then the insulator of breakage is changed.Traditional pincers of pulling pin are as shown in Figure 1, comprise by stock 101 and quarter butt 102 constituting " L " type main body, are provided with coupler body 104 in quarter butt 102 ends, are provided with pair of balanced bar 102 in intersection 105 both sides of stock 101 and quarter butt 102.During use; The free end 106 of hand-held stock 101 is inserted into the coupler body 104 of quarter butt 102 ends 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, make insulator disengagement up and down.The pincers of pulling pin of this structure have following defective:
1, connecting pin commonly used has R type and two kinds of structures of W type.Shown in Figure 2 is the structure of R type connecting pin, and it comprises a collar extension 61.The coupler body 104 of the pincers of pulling pin is inserted in the collar extension 61 of connecting pin and can extracts connecting pin.Therefore, traditional pincers of pulling pin can be used in and extract R type connecting pin.Yet, for W type connecting pin, referring to Fig. 2, the opening 82 at two collar extensions 81 and a middle part about this W type connecting pin comprises.Because two collar extensions 81 are all at sidepiece, and connecting pin is ductile, 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 subsequent use pin and just can change new insulator, and this can't realize when operating in the open air.
2,,, therefore also can't operate because coupler body 104 can't be deep into the connecting pin position for H anti-fouling type large distance insulator.
3, be fixed on same position owing in operating process, act on fulcrum, and local stress concentration causes the porcelain vase explosion easily, brings accident to service work.
4, when operation, pair of balanced bar 102 is also very easily run into intact porcelain vase, and collision is prone to cause porcelain vase to break.
Summary of the invention
What the utility model will solve is the problems referred to above that prior art exists, and aims to provide a kind of simple in structure, practicality and high efficiency, easy to operate, safe in utilization, is applicable to the new tool of the various model insulator connecting pins of choosing.
For addressing the above problem; The utility model adopts following technical scheme: a kind of pin removal of all types of insulator connecting pins that are used to choose; The connecting rod that comprises main part; Described connecting rod front end is provided with the semi-circular hook of pulling pin, and 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 is provided with.
The beneficial effect of the utility model is:
1, because the two ends that connect are respectively equipped with the pull pin hook and the shovel of pulling pin, and the described hook of pulling pin can act on R type connecting pin, the described shovel of pulling pin can act on W type connecting pin, makes the utility model can not receive the restriction of insulator model when using.The line maintenance personnel use this instrument, can realize the replacing to various model insulators on 35kV-500kV strain insulator and the straight line pole, have improved the efficient of power transmission lines overhauling work, reduce the activity duration on maintainer's bar, thereby it are dangerous to reduce work high above the ground.Particularly because the light practicality of the utility model instrument, easy and simple to handle, safe and reliable will be established 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, was 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,, when operation, can not collide porcelain vase, thereby can not cause the accident of porcelain vase to crash through because the utility model is simple and compact for structure.
4, platypelloid type is pulled pin to shovel with connecting rod and is ± 10 degree angles setting of 145 degree, and one side making to pull pin to shovel and can enter into the enterprising line operate in connecting pin position smoothly, and active force can effectively be delivered on the connecting pin, can reduce the moment loss in the transmittance process on the other hand again.
As a kind of improvement of the utility model, connecting rod is long strip type, and is integral formula casting with the described hook of pulling pin with the shovel of pulling pin and is connected.This structure, the bulk strength of product is high, helps the transmission of active force.
As a kind of improvement of the utility model, the said hook of pulling pin comprises and described semi-circular part that links to each other and the extension that is connected with described semi-circular part end of being connected.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.
As a kind of improvement of the utility model, the said shovel of pulling pin is terminal to be W type notch design, perhaps tack or semi-circular design, and the former is an optimum structure, when horizontal sliding, can carry out good cooperating with W type connecting pin, has protected the integrality of connecting pin effectively.W type connecting pin after extracting is reusable, thereby the insulator that can in the shortest time, will newly change is fixed to corresponding position.
As a kind of improvement of the utility model, described connecting rod bottom surface is " V " type structure of indent, and the breakover point of said " 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 frangible.
