Abstract
The utility model discloses a jacking tool for a tower ground wire clamp, which solves the technical problem existing in the prior art that adjustment of the ground wire clamp of a power transmission tower is limited by a working space. The jacking tool comprises a jacking support base (1); two guide rods (2) are fixedly arranged on the jacking support base (1) in parallel; an ejector rod cross arm (3) is movably sleeved on the two guide rods (2); the center of the bottom surface of the ejector rod cross arm (3) is abutted against the top end of a screw (4); the bottom end of the screw (4) penetrates through a nut in a nut operating rod (5) first and penetrates downward from a screw nut arranged in a center hole of the jacking support base (1); a platform (6) of the ejector rod tower ground wire clamp is arranged on the ejector rod cross arm (3); a hanging ground wire slot (7) is arranged on the ejector rod cross rod (3); and a tower cross arm fixing frame (8) is arranged on the top ends of the two guide rods (2). The jacking tool disclosed by the utility model is simple in structure and easy to implement.
Description
Technical field
The utility model relates to the lifting instrument of the ground wire wire clamp on a kind of electric power transmission steel tower.
Background technology
When the shaft tower of electric power transmission line is distributed in the goaf, in rainwater multiple season, because surface subsidence, very easily cause transmission tower inclination and ground insulator to take a step, add that the residing geographical environment of shaft tower is complicated, repairing brings many difficulties to circuit, and the manual labor and the operation that have strengthened the maintainer are dangerous.When adjustment wire insulation is taken a step, there is complete ready-made instrument to use, takes a step the aspect owing to without suitable service kit, making adjustment ground wire wire clamp run into difficulty but adjust the ground wire wire clamp.When steel tower is changed overhead ground wire use jack and other instrument, also there is fixed point free, adjustment work can't be carried out.Employing uses anchor ear to hang the mode of coaster at bar, because hoist-hole apart from long, hangs ground wire not in place.In addition, because spacing is very little between ground wire and the cross arm of tower, in the ground wire lifting process, use traditional lifting tool to carry out.
Summary of the invention
The utility model provides a kind of pole tower ground wire wire clamp jacking tool, solved prior art whole ground wire wire clamp take a step aspect owing to making the technical problem of adjusting the very large difficulty of ground wire wire clamp existence without suitable service kit.
A kind of pole tower ground wire wire clamp jacking tool, comprise the lifting-up support base, be fixedly installed two parallel guide rods at the lifting-up support base, movable sleeve is connected to the push rod cross-arm on two guide rods, the bottom surface centre of push rod cross-arm and the top apical grafting of leading screw, the bottom of leading screw is passed first in the nut that arranges from the centre bore of lifting-up support base behind the screw in the screw action bars and is passed downwards, be provided with the platform of jacking pole tower ground wire wire clamp at the push rod cross-arm, be provided with the hanging ground-wire groove at the push rod cross-arm, be provided with steel tower cross-arm fixed mount on the top of two guide rods.
Be provided with chain colligation hole at the lifting-up support base, in chain colligation hole, be provided with around fixing chain.
The utility model is simple in structure, and is easy to implement, solved overhead ground wire and cross-arm hypotelorism, and hoisting tool can't use, a difficult problem that causes service work to stagnate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of pole tower ground wire wire clamp jacking tool, comprise lifting-up support base 1, be fixedly installed two parallel guide rods 2 at lifting-up support base 1, movable sleeve is connected to push rod cross-arm 3 on two guide rods 2, the bottom surface centre of push rod cross-arm 3 and the top apical grafting of leading screw 4, the bottom of leading screw 4 is passed first in the nut that arranges from the centre bore of lifting-up support base 1 behind the screw in the screw action bars 5 and is passed downwards, be provided with the platform 6 of jacking pole tower ground wire wire clamp at push rod cross-arm 3, be provided with hanging ground-wire groove 7 at push rod cross-arm 3, be provided with steel tower cross-arm fixed mount 8 on the top of two guide rods 2.
Be provided with chain colligation hole 9 at lifting-up support base 1, in chain colligation hole 9, be provided with around fixing chain 10.
The utility model main thought is loosening to the ground wire wire clamp, and the from top to bottom lifting by original changes from lower to upper jacking into, has solved overhead ground wire and cross-arm hypotelorism, the difficult problem that hoisting tool can't use.When the utility model uses at steel tower, the instrument top is fixed on the ground wire cross-arm, ground wire is snapped in the instrument ground wire casing again, utilize bottom leading screw jacking ground wire, reach the purpose of maintenance.During the maintenance of concrete bar, because the ground wire cross-arm is oblique shape casting pig, the cross-arm fixing point at a tool using top easily comes off, and should be used in conjunction with concrete burr bottom the instrument around fixing chain, to be fixed on the concrete club body around fixing chain 10, guarantee instrument safety in use.
