Abstract
The utility model relates to a level-type grounding down conductor lifting tool. The lifting device comprises a clamping device, a pressing bar and a support bar. The clamping device comprises a connection part, a top plate, a clamping plate and a cover plate. The top plate is fixed at the front end face of the connection part. A screw hole is respectively arranged in corresponding positions of the clamping plate and the top plate. Clamping bolts are installed in the two corresponding screw holes during usage. The cover plate is fixed at the front end face of the top plate or the cover plate. A connection plate with a connection hole is fixed on the rear end face of the connection part. The front end of the pressing bar is fixed at the rear end of the connection plate. A support hole is arranged in the bar body of the support bar. The connection hole of the connection plate aligns with the support hole and a connection bolt is installed. A grounding down conductor is installed in the space formed by the clamping plate, the top plate and the cover plate and is clamped and fixed through the clamping bolt. Then the pressing bar is pressed downwards and lifting of the grounding down conductor is achieved. The lifting tool is advantaged by simple on-site operation and short working time, reduces the personnel labor intensity and raises the working efficiency.
Description
Technical field
The utility model relates to a kind of hoisting tool, particularly a kind of lever down conductor hoisting tool.
Background technology
Electric power line pole tower earthing device comprises earth electrode and down conductor.Earth electrode is again earth electrode, refers to the metallic conductor of imbedding in ground and directly contacting with soil, in order to the earth leakage current.Down conductor is the wire that connects lightning conducter and earth electrode.Its effect is for conducting the lightning current on lightning conducter, flowing into the earth by earth electrode.Down conductor is connected with shaft tower by bolt.
Every year in measuring the work of electric power line pole tower power frequency earthing resistance, must open the connecting bolt of down conductor and shaft tower, can measure, after down conductor is taken apart, to underground, there is certain dilatability (approximately 30～50mm), due to without Special-purpose lifting instrument this with regard to for the installation of connecting bolt brings certain difficulty, increased accordingly personnel labor intensity and operating time.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lever down conductor hoisting tool, thereby in the test of electric power line pole tower power frequency earthing resistance, reduces the operating time, alleviates personnel labor intensity, increases work efficiency.
For solving above technical problem, the technical solution adopted in the utility model is:
A kind of lever down conductor hoisting tool, comprise clamping device, press thick stick and supporting lever, described clamping device comprises connecting portion, top board, clamping plate and cover plate, top board is fixed on connecting portion front end face, on the correspondence position of clamping plate and top board, respectively have a screw, during use, in two corresponding screws, pack fishbolt into, cover plate is fixed on the front end face of top board or cover plate, connecting portion rear end face is fixed with the connecting plate that has connecting hole, presses thick stick front end to be fixed on the rear end of connecting plate; Support on bar body and have supported hole, the connecting hole of connecting plate packs connecting bolt into after aliging with supported hole.
During use, down conductor is arranged in the space of clamping plate, top board and cover plate formation, is fixedly clamped, then to pressing down the lifting of pressing thick stick can be grounded downlead with fishbolt.
On described support bar body, have at least two supported holes, the object that a plurality of supported holes are set is to regulate clamping device and press the setting height(from bottom) of thick stick on supporting lever.
The utility model is simple in structure, is easy to carry, easy to implement, and applicability is stronger, can meet transmission route survey shaft tower power frequency earthing resistance, recovers the requirement of down conductor connecting bolt.Execute-in-place is simple, and the operating time is short, subtracts and has taken turns personnel labor intensity, has improved operating efficiency.
