Abstract
The utility model relates to the technical field of insulating plate ladders, in particular to a pulley type insulating plate ladder which is mainly used for overhead transmission lines with 66kV voltage class and above. The pulley type insulating plate ladder comprises pulleys, brackets and a ladder; the brackets are fixedly connected with a seat plate; two brackets at each side are connected by a connecting rod; pulleys are respectively arranged at two ends of a shaft, two ends of the shaft are respectively connected on the two opposite brackets, and the upper parts and the lower parts of the brackets are respectively connected with two shafts; and the ladder is clamped between an upper group of pulleys and a lower group of pulleys. In the utility model, the vertical vibration of the insulating plate ladder can be eliminated completely, the center of gravity of operating personnel can be stabilized, the insulation combined gap when the operating personnel enters or exits a strong electric field is increased by 45cm-50cm, the damage on a lead caused by a hanger of the insulating plate ladder can be alleviated, the practicability is stronger, and the safety can be improved obviously when the operating personnel is in potential work. The pulley type insulating plate ladder is mainly suitable for potential work such as the overhead transmission lines and the like with 66kV voltage class and above.
Description
Technical field
The utility model relates to the technical field of insulating slab ladder, relates in particular to a kind of coaster formula insulating slab ladder, and it is mainly used in overhead transmission line equipotential live line work on 66kV and the above electric pressure.
Background technology
At present, 66kV and above electric pressure overhead transmission line carry out generally adopting in the equipotential live line work traditional insulating slab ladder, and promptly the operating personnel utilizes the simple ladder of being made by insulation materials epoxy resin to move to highfield.But because of operating personnel's shift action on ladder can cause insulating that combinational gap reduces, the insulating slab ladder produces vertical tremor and reduces insulating slab ladder mechanical strength, operating personnel and lose the generation that thereby a series of accidents such as fall in the high-altitude, lead damage and problem take place center of gravity easily.
Summary of the invention
The utility model is at above-mentioned problems of the prior art, a kind of novel coaster formula insulating slab ladder that provides a kind of security performance to significantly improve.It can eliminate insulating slab ladder vertical tremor, and the increase operating personnel enters and withdraw from the combinational gap in the highfield process, stablizes operating personnel's center of gravity, reduces the damage that insulating slab ladder hook causes lead.
The technical scheme of the purpose of the utility model realization invention is as follows:
Coaster formula insulating slab ladder comprises pulley, support and ladder; Support is fixedlyed connected with seat board; Two supports of every side are connected by connecting rod; Pulley is located at a two ends respectively, and the two ends of axle are connected on relative two supports, and the support top and the bottom are connected with two axles respectively; Ladder is located at the centre of two groups of pulleys up and down.
Described support is connected four jiaos of seat board.
Described ladder is the insulating slab ladder, and ladder is by connecting clamp, is installed on up and down in the middle of two groups of pulleys.
Described ladder is the epoxy resins insulation ladder.
The two ends of described seat board are connected with the external insulation pull rope.
Described pulley is made by insulation materials, and the outer is outstanding.
Described insulation materials is a nylon material.
The utility model compared with prior art, can eliminate insulating slab ladder up-down vibration fully, stablize operating personnel's center of gravity, the increase operating personnel enters and withdraws from the insulation combinational gap 45cm-50cm in the highfield process, reduce the damage that insulating slab ladder hook causes lead, practicality is stronger, and the security performance of staff when the current potential operation is significantly improved.The utility model mainly is applicable to overhead transmission line equipotential live line work on 66kV and the above electric pressure.
