Abstract
An adjusting support for an electric power circuit pole and tower cross arm is used for assisting in achieving the adjustment operation of the direction of the electric power circuit pole and tower cross arm. The adjusting support comprises a first supporting frame, a second supporting frame, a screw rod, a nut and a ratchet wrench, the first supporting frame and the second supporting frame are both arc-shaped supports, a set of rolling wheels is arranged on each arc-shaped support, the rolling wheels are evenly arranged in the radial direction of the arc-shaped supports, one end of the first supporting frame is hinged to one end of the second supporting frame through a pin shaft, and the other end of the first supporting frame and the other end of the second supporting frame are connected and fastened through the screw rod and the nut. The adjusting support has the advantages of being simple in structure and convenient to use, the direction of the electric power circuit pole and tower cross arm can be adjusted, the labor intensity and the danger coefficients for working high above the ground of operators are lowered, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement, especially a kind of bracing or strutting arrangement being applicable to electric power line pole tower cross-arm orientation adjustment, belongs to generating, power transformation or distribution technique field.
Background technology
In power circuit erection process, cross-arm on overhead line structures and porcelain piece installation workload are very large, especially when to the cross-arm of a minute pole, angle pole, terminal pole, double-deck circuit and multilayer line bar and porcelain piece installation, often run into the work high above the ground situation of two or three hours closely on same shaft tower simultaneously by two people, not only labour intensity is large, and danger coefficient is quite high.
For addressing the above problem, power construction personnel adopt the installation that completes on the ground cross-arm and porcelain piece, then by the operating type of electric pole integral assembly, thereby reduce danger coefficient and increase work efficiency.But, above-mentioned installation process can not guarantee cross-arm orientation and the angle that sets up wire is met to detail design requirement, also need the orientation of cross-arm to adjust, and at present owing to lacking special-purpose bracing or strutting arrangement, make the adjusting operation in cross-arm orientation become the bottleneck that restriction operating efficiency improves.
Summary of the invention
The object of the invention is to the drawback for prior art, provide a kind of simple in structure, easy to use, can reduce overhead line structures cross-arm and porcelain piece installment work intensity and danger coefficient, the electric power line pole tower cross-arm adjustment of increasing work efficiency is supported.
Problem of the present invention realizes with following technical proposals:
A kind of electric power line pole tower cross-arm adjustment is supported, it comprises the first bracing frame, the second bracing frame, screw rod, nut and ratchet spanner, described the first bracing frame and the second bracing frame are arc stent, one group of roller is set on arc stent, described roller is radially evenly arranged along arc stent, described first bracing frame one end and second bracing frame one end are hinged by bearing pin, and their other ends are connected, lock with nut by screw rod.
Above-mentioned electric power line pole tower cross-arm adjustment is supported, and described first bracing frame one end is provided with the first bracing frame hinged seat, at its other end, the first locking bed is set, and described the first locking bed outboard end is provided with screw rod groove.
Above-mentioned electric power line pole tower cross-arm adjustment is supported, and described second bracing frame one end is provided with the second bracing frame hinged seat, at its other end, the second locking bed is set, and described the second locking bed is provided with shoulder hole, in described shoulder hole larger diameter end, self-aligning bearing is set.
Above-mentioned electric power line pole tower cross-arm adjustment is supported, and described screw rod and ratchet spanner are integral type structure.
The first bracing frame of the present invention and the second bracing frame are hinged by bearing pin, when needs are during to overhead line structures cross-arm orientation adjustment, arc stent by the first bracing frame and the second bracing frame surrounds the hollow collar, and be sleeved on the cylindrical outside of overhead line structures, then by ratchet spanner, bolt and nut is locked; Because the present invention is provided with roller on the first bracing frame and the second bracing frame, the overhead line structures cross-arm being disassembled can rotate to the angle of setting like a cork in roller plane, and then by overhead line structures cross-arm and the fixing assembling of overhead line structures cylinder; The present invention is provided with self-aligning bearing on the second locking bed of the second bracing frame, and it coordinates the adjustment that can realize screw rod direction with screw rod; The present invention arranges screw rod groove at the outboard end of first bracing frame the first locking bed, with the ratchet spanner screw rod that is integral type structure both can be first and nut assembling after enter described screw rod groove again with fastening nuts, also after removable lower nut, pierce into screw rod groove, and then mounting nuts.In a word, the present invention has feature simple in structure, easy to use, can not only realize the adjustment to overhead line structures cross-arm orientation, and has reduced operator's labour intensity and work high above the ground danger coefficient, has improved operating efficiency.
