Abstract
The utility model relates to an instrument for removing nails, and particularly relates to a grounded screen underpinning lifting instrument. The grounded screen underpinning lifting instrument comprises a single-arm screw jack with a forcer, wherein the forcer of the single-arm screw jack is provided with a starting board, and one end of the starting board is provided with a V-shaped opening and the upper and lower surfaces of the starting board are perpendicular to the motion direction of the forcer. According to the utility model, the forcer of the existing single-arm screw jack is provided with the starting board with the V-shaped opening, and a ground stud knocked in the ground can be easily and rapidly pulled out, so that the ground stud can be recycled, and the utilization ratio of the ground stud is improved; and the instrument provided by the utility model also can remove implements, such as the ground stud which is knocked in the ground and is not easy to pull out, and the instrument provided by the utility model has the advantages of ingenious design, simple structure, and simplicity and convenience in manufacture.
Description
Technical field
The utility model is a kind of instrument of pulling out nail, is specially a kind of grounded screen pile and pulls up instrument.
Background technology
The quality of thunder resisting equipment, Resistance of Grounding Grids is related to the safe operation of transformer station's electric fixtures, the ground resistance size directly embodied electric installation with " " good degree that contacts, therefore want regularly measure to grounded screen electric resistance.In recent years, because requirements of one's work such as scrap build, increase-volume, enlarging relate to the grounded screen retrofit work is on the increase, the test job amount of Resistance of Grounding Grids is also strengthening.The test requirements document of Resistance of Grounding Grids is relatively strict, must carry out in the autumn and winter dry season, and autumn and winter season soil all be in freezing state.In the grounding net of transformer substation test job, the electric current utmost point and voltage pole (being ground stud) are pounded in the frozen soil so that test; The electric current utmost point and voltage pole are generally used diameter 40-50mm, and the screw-thread steel of long 1.5m is processed, and have and the similar structure of bolt.After test job was accomplished, the electric current utmost point and voltage pole (ground stud) were because entering ground is darker, and it is bigger to conduct oneself with dignity; And the instrument that pulls up that lacks specialty, when pulling up with regard to time-consuming, expend bodily strength, often occur because frozen soil obstacle ground stud can not pull out; Ground stud is permanent to be stayed in ground, causes waste.And auto repair is commonly used to a kind of single armed jackscrew, can be light and handy lift weight such as automobile, so consider this single armed jackscrew is improved so that it can be used in the work that pulls up of grounded screen pile.This kind single armed jackscrew has following structure: comprise master arm and the base that is hinged on the master arm bottom, both form the principal arm of jack together; One end of secondary support arm is hinged on the nearly middle part of master arm through bearing pin, and secondary support arm can rotate around bearing pin; The other end of secondary support arm is equipped with the top; Secondary support arm is provided with feed screw nut and screw mandrel, and feed screw nut and screw mandrel revolve joins, and an end of screw mandrel is installed in the top of master arm through bearing support, and this end of screw mandrel also is provided with rotating spanner.During use, rotating spanner is joined through revolving of screw mandrel and nut, drives secondary support arm and with the bearing pin is fulcrum and rotate, and master arm also is that fulcrum rotates with the base simultaneously, and the top of secondary support arm will vertically move up and down, thereby can jack-up or put down weight.
Summary of the invention
The utility model lacks the problem that special instrument causes pulling up difficulty in order to solve after the grounded screen pile is pounded ground, provides a kind of grounded screen pile to pull up instrument.
The utility model is to adopt following technical scheme to realize: a kind of grounded screen pile pulls up instrument; Comprise the single armed jackscrew that has the top, one one end is installed in the top of single armed jackscrew opens the nail-plate V-type gap, that upper and lower surfaces is vertical with the direction of motion of top.During use, the grounded screen pile is pulled up instrument place near the ground stud, choose correct position, the nail nipping integrated circuit board of V-type gap is gone into the ground stud lower head, rotating spanner, the top has driven nail-plate and has risen gradually, and ground stud will be extracted gradually.Play nail-plate and have the V-type gap, be similar to goat's horn, simple structure can conveniently be blocked ground stud.
The utility model is equipped with the nail-plate that rises of a V-shaped gap through the top in existing single armed jackscrew, can lightly extract the ground stud that hammers into ground fast, makes ground stud to reuse, and has improved the utilization rate of ground stud.The utility model also can be used to pull out be similar to ground stud such hammer into the implements that ground is not drawn out easily.The utility model design is ingenious, simple in structure, simple for production.

Fig. 2 the utility model use sketch map.
The 1-master arm, the 2-base.The secondary support arm of 3-, the 4-top, 5-plays nail-plate, 6-bearing pin, 7-feed screw nut, 8-screw mandrel, 9-bearing support, 10-rotating spanner, 11-ground stud, 12-ground stud head.
The specific embodiment
A kind of grounded screen pile pulls up instrument, comprises the single armed jackscrew that has top 2, one one end is installed in the top 2 of single armed jackscrew opens a nail-plate 5 V-type gap, that upper and lower surfaces is vertical with the direction of motion of top.Existing single armed jackscrew comprises master arm 1 and the base 2 that is hinged on the master arm bottom, and both form the principal arm of jack together; The nearly middle part of master arm is hinged with secondary support arm 3 through bearing pin 6, and secondary support arm can rotate around bearing pin; The other end of secondary support arm 3 is equipped with top 4; Secondary support arm is provided with feed screw nut 7, and feed screw nut 7 is revolved with screw mandrel 8 and joined, and an end of screw mandrel 8 is installed in the top of master arm through bearing support 9, and this end of screw mandrel also is provided with rotating spanner 10.During concrete the application, the grounded screen pile is pulled up instrument place near the ground stud 11, choose correct position; The nail-plate 5 that rises that will have the V-type gap snaps in ground stud head 12 belows and chucking, and rotating spanner 10 is joined through screw mandrel and revolving of feed screw nut 7; Screw mandrel 8 outwards withdraws from, and driving secondary support arm is that fulcrum rotates with bearing pin 6, and master arm 1 is that fulcrum rotates round about with base 2 also simultaneously; The top 4 of secondary support arm 3 has driven nail-plate 5 and has risen gradually, and ground stud 11 will be extracted gradually.
