Abstract

A vertical double-hanging clamp is characterized by comprising two symmetrically arranged cross arm angle steel clamping apparatuses (2), two sets of lead screws (1) connected with the cross arm angle steel clamping apparatuses (2) respectively, and a balancing pull rod (3) located in the middle of the two cross arm angle steel clamping apparatuses (2) and connected with the two cross arm angle steel clamping apparatuses (2). The beneficial effects of the invention are that: the vertical double-hanging clamp enables the whole work to be operated conveniently, effectively balances the tensile forces generated by tightening the lead screws to thereby not enable the tower materials to deform, enables the personal injury risk during the tightening process to be reduced effectively, does not need the help of other tools when being installed, can be installed rapidly during the installation process, and enables the working risk to be reduced.

Description

Vertical two elevator
Technical field
The invention belongs to electric power apparatus examination instrument, particularly 110kV and above transmission line cross-arm angle steel head-on down time the replacing of linear insulator chain and erecting tools structure.
Background technology
Insulator is a kind of special insulation control, insulator plays two basic roles in overhead transmission line, namely support wire and prevent electric current return ground, these two effects must be guaranteed, insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, use and the service life of whole piece circuit will be damaged.In the process that transmission line runs, due to the reason such as destruction, thunder and lightning, pollution flashover of external force, causing insulator self-destruction or lose insulating effect, for ensureing the safe operation of transmission line, needing to change deteriorated insulator.Carrying out in fact-finding process to the transmission line of Pu'er electrical network 110kV, find that the electric power line pole tower cross-arm tower material of Pu'er electrical network is divided into water holding material and non-water holding material, on original replacing insulator instrument basis, if cross-arm tower material is non-water holding material (mouth down met by angle steel), existing instrument has been difficult to this type of work, or in Renewal process, occur that tower material discontinuity causes tower material to be out of shape, increase the risk of operation.
Existing power tool and shortcoming:
Existing replacing cross-arm tower material is in the instrument of the linear insulator of non-water holding material (mouth down met by angle steel), the dual-purpose straight line drop hanger card that usual employing is developed voluntarily, but the existence of this type of jig is tightened up in screw mandrel process and is caused both sides tower material unbalance stress, the appearance of tower material deformation, this will significantly increase the risk factor of this work.
Summary of the invention
Object of the present invention provides a kind of safe and reliable vertical pair of elevator to overcome the defect of above-mentioned prior art existence just.
The object of the invention is to realize by following technical solution.
Vertical two elevator, the present invention is characterised in that, comprise two cross-arm angle steel jigs, two sleeve screw rods is connected with cross-arm angle steel jig respectively and be positioned at two cross-arm angle steel jigs centres and the balancing pull rod be attached thereto; Wherein, screw mandrel is screwed in by the wire rod thread hole on cross-arm angle steel jig; The cross bar that balancing pull rod comprises center montant and is fixedly connected with montant, offer bolt connecting hole in cross bar both sides, adopt bolt by inserting bolt connecting hole and the bolt hole offered on cross-arm angle steel jig make balancing pull rod cross bar two ends be connected with cross-arm angle steel jig respectively.
Cross-arm angle steel jig of the present invention comprises superposed rectangle card and is positioned at the fixture block of side, bottom, offers a draw-in groove between card and fixture block.
The wire rod thread hole of cross-arm angle steel jig is set to open type hole by the present invention, namely breach is offered along wire rod thread hole axial line, and offer a fixing hole in cross-arm angle steel jig termination along breach, by adopting set bolt, the screw mandrel (1) in wire rod thread hole is fixed.
When cross-arm angle steel be head-on down time jig fixed form, whole installation process is convenient and swift, and the application of balancing pull rod makes screw mandrel can not cause the unbalance stress of both sides cross-arm angle steel in tightening process, the distortion of tower material can not be caused, make it be not easy the distortion because of tower material and cause the risk of effect.。Connect two assembly pulleys by screw mandrel to form, vertical two elevator is made up of the balancing pull rod of two cross-arm angle steel jigs, two sleeve screw rods and centre.Jig plays fixing effect, and screw mandrel plays stringing lead and to relax insulator, and the balancing pull rod of centre plays the stressed effect in balance both sides, prevents tower material from causing distortion by force unbalance.
In linear insulator chain Renewal process, the fixing of jig does not need by other aid, can Fast Installation, effectively reduces the injury to person when activity duration of work high above the ground personnel and tower material deform, reduce risk in more changing jobs.
Cross-arm angle steel jig of the present invention is for being arranged on cross-arm angle steel, and screw mandrel is used for stringing lead, and balancing pull rod is for balancing the stressed of both sides, is a spotlight of jig of the present invention.
Beneficial effect of the present invention is: the present invention makes whole operation convenient, and effective balance tightens up the pulling force that screw mandrel produces, and is unlikely to cause tower material to be out of shape, can effectively reduces personal injury risk in tightening process; Do not need during installation by other Work tools, can Fast Installation in installation process, reduce the risk of this type of operation.
