Description

A kind of wiring pile extractor

Technical field

The utility model relates to a kind of instrument, and being used for of using in a kind of electric power system specifically will be embedded in the instrument that underground wiring pile is extracted.

Background technology

, in order to guarantee safety, during the electric power system maintenance maintenance, need to connect ground wire on the device of maintenance maintenance after power failure, this work that is absolutely necessary.The access of ground wire is that a wiring pile is squeezed in soil, and the ground wire (copper conductor) under then drawing from equipment is connected on wiring pile.Wiring pile is a copper rod that is about 1.5m, and the lower end of wiring pile is provided with the cone point, and the top of wiring pile is provided with the hole that connects ground wire, and the wiring pile that connects the place, hole of ground wire is typically provided to the flat plane, to facilitate ground wire, connects.The degree of depth of being driven underground of wiring pile is darker, and the safety effect that ground wire plays is larger.Wiring pile is being imbedded when underground and can squeezed into sledgehammer etc., but just very difficult while extracting, have no way of doing it while easily pulling out a nail when nailing, deep buried wiring pile is extracted and need to be wasted time and energy, to knock after making it loosening and extract with about iron hammer when people extract wiring pile in the past, can produce effect for imbedding more shallow wiring pile like this, but burial depth is when very large, often unusual effort.So repeatedly hit and also wiring pile can be damaged.In order easily to extract wiring pile, some operating personnel is often simple squeezing into when squeezing into wiring pile, do not reach the degree of depth of regulation, can have potential safety hazard like this.

The utility model content

The utility model technical issues that need to address are to provide a kind of specific purpose tool that wiring pile easily can be extracted, the problem that is difficult to extract to solve wiring pile.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wiring pile extractor, comprise the column with base, the upper end of column is by the lever of the hinged end of bearing pin with handle, the lifting end of lever connects two steel wire ropes by the transverse axis of horizontally set, and the pincers of embracing of wiring pile are blocked in the lower end connection one of steel wire rope; Described armful of pincers mainly consist of pincers piece I and pincers piece II, the inner of pincers piece I and pincers piece II is the jaw of holding wiring pile tightly that inner surface arranges the tooth line, pincers piece I and pincers piece II are plugged in together and pass through pin hinged, and two steel wire ropes are connected to pincers piece I and clamp on the contiguous block I and contiguous block II at piece II two ends; Be provided with the bayonet socket post of the flat column of wiring place that can block wiring pile in the side of the lever that is positioned at the pin joint place.

Further improvement of the utility model is: the upper and lower surface of described lever is provided with reinforcement.

Further improvement of the utility model is: described column comprises the end column of upper pillar stand and hollow, described base is fixed on below end column, upper pillar stand is plugged in the endoporus of end column, and on upper pillar stand and end column, correspondence arranges some flexible location holes and by alignment pin, the position of upper pillar stand and end column fixed; Described lever is hinged on the upper end of upper pillar stand.

Further improvement of the utility model is: be provided with the split pin that prevents that pin from coming off on the pin of described armful of pincers.

Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:

The utility model can easily be extracted wiring pile, has solved the problem that wiring pile is difficult to extract, and can the butted line stake not cause damage.While using the utility model to pull out wiring pile, at first be stuck on the flat horizontal surface of wiring place of wiring pile with two bayonet socket posts on lever, then promote lever around wiring pile, wiring pile is rotated, if the difficulty of rotation, column and lever are close together, exert oneself together, until wiring pile rotates.Then with the base support of column on ground, embrace in the position of wiring pile near ground embracing the pincers card, and the pincers piece I that will embrace pincers with pin is in the same place with pincers piece II pin joint, then to the handle of depress lever, at this moment, embrace the pincers piece I of pincers and clamp the piece II under the pulling force effect of steel wire rope, around pin, rotating, the jaw of pincers piece I and pincers piece II is with wiring pile cylinder chucking, and wiring pile is stirred.Wiring pile can not be extracted if once press lever, again jaw is arranged on subaerial position, press again lever and make the wiring pile end distance that rises again, until wiring pile can be extracted.

The utility model uses lever principle, can increase and extract strength.The arranging of reinforcement on lever can prevent that lever from exerting oneself when excessive to occur bending and deformation.Column of the present utility model is flexible in end column by upper pillar stand, makes the height of column reach suitable operation height, and the convenient operation personnel firmly.Of the present utility model armful of pincers pull by two steel wire ropes, make the pincers piece I of embracing pincers and the jaw of pincers piece II can block wiring pile, and kilocalorie tighter more firmly, and the inner surface of jaw arranges the tooth line makes the enclasping force between abaculus and wiring pile larger.Embrace on the pin that clamps split pin is set, can prevent from embracing pincers piece I and the disengagement of pincers piece II of pincers, avoid operating casualty accident.
