Description

A kind of wiring pile extractor

Technical field

The present invention relates to a kind of instrument, 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 connect ground wire at the device of maintenance maintenance after the power failure, this work that is absolutely necessary.The access of ground wire is that a wiring pile is squeezed in the soil, and the ground wire (copper conductor) under will drawing from equipment then is connected on the wiring pile.Wiring pile is a copper rod that is about 1.5m, and the lower end of wiring pile is provided with the awl 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, connects to make things convenient for ground wire.The degree of depth of being driven underground of wiring pile is more dark, and the safety effect that ground wire plays is more big.Wiring pile can be squeezed into sledgehammer etc. when underground imbedding, but it is just very difficult when extracting, have no way of doing it when pulling out a nail easily when nailing, deep buried wiring pile is extracted and need be wasted time and energy, be to extract after making it loosening with knocking 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 big, often unusual effort.Hit so repeatedly and also wiring pile can be damaged.In order to extract wiring pile easily, some operating personnel often is simple squeezing into when squeezing into wiring pile, does not reach the degree of depth of regulation, can have potential safety hazard like this.

Summary of the invention

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

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of wiring pile extractor, comprise the column of being with base, the upper end of column has the lever of handle by the hinged end of bearing pin, 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 are made of pincers piece I and pincers piece II, the inner of pincers piece I and pincers piece II arranges the jaw of holding wiring pile tightly of tooth line for inner surface, pincers piece I and pincers piece II are plugged on together and are hinged by pin, and two steel wire ropes are connected on the contiguous block I and contiguous block II at pincers piece I and pincers 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 present invention is: the upper and lower surface of described lever is provided with reinforcement.

Further improvement of the present invention is: described column comprises the end column of upper pillar stand and hollow, described base is fixed on below the end column, upper pillar stand is plugged in the endoporus of end column, correspondingly on upper pillar stand and the end column some flexible location holes is set and by the fixed-site of alignment pin with upper pillar stand and end column; Described lever is hinged on the upper end of upper pillar stand.

Further improvement of the present invention is: the pin of described armful of pincers is provided with the split pin that prevents that pin from coming off.

Because the technological progress of having adopted technique scheme, the present invention to obtain is:

The present invention can easily extract wiring pile, has solved the problem that wiring pile is difficult to extract, and can the butted line stake not cause damage.When using the present invention 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 the lever, promote lever around wiring pile then, wiring pile is rotated, if the difficulty of rotation is then closed up column and is in the same place with lever, exert oneself together, rotate up to wiring pile.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 pull of steel wire effect, rotate around pin, 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, then again jaw is installed in subaerial position, press again lever make wiring pile rise again an end distance from, up to wiring pile being extracted.

The present invention uses lever principle, can increase to extract strength.The arranging of reinforcement on the lever can prevent that lever from exerting oneself to occur bending and deformation when excessive.Column of the present invention is flexible in end column by upper pillar stand, makes the height of column reach suitable operation height, is convenient to operating personnel firmly.Of the present invention armful of pincers are by two steel wire ropes pullings, make the pincers piece I of embracing pincers and the jaw of pincers piece II can block wiring pile, and kilocalorie more tight more firmly, and the inner surface of jaw arranges the tooth line makes the power of holding tightly between abaculus and the wiring pile bigger.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.
