Abstract
The utility model discloses an equipotential ladder which comprises a main rod that is longitudinally arranged, and is characterized in that the top of the main rod is provided with a hoisting ring, and the middle part and the bottom of the main rod are respectively provided with a first transverse ladder and a second transverse ladder. The equipotential ladder has the outstanding advantages that tools are simple, the on-site operation is convenient, the process of entering the electric field of equipotential operating personnel is smooth, and the like.
Description
Technical field
The utility model relates to electric power system live line working Work tool, delivery operating personnel's utensil when referring to charged dismounting straight line insulator string especially, specifically a kind of equipotential ladder.
Background technology
For the 500kV line live-line work, the process that the equal potential working personnel enter highfield is the important ring that live line working is normally carried out.How guaranteeing the equal potential working personnel in entering the process of highfield, promptly will satisfy the requirement of the combinational gap of " safety " regulation, accomplish that again execute-in-place is simple, the operating personnel passes in and out conveniently, is the important topic that needs solution.
The mode that equal potential working personnel commonly used at home at present carry out highfield mainly contains: (1) adopts the climbing insulated flexible ladder to enter; (2) adopt along the hard ladder of insulation laterally ride into; (3) adopt and to take insulation hanging basket fixed length camber line and enter.Method (1) has that Work tool is simple, execute-in-place advantage easily, but single-circuit steel tower only is applicable to the limit phase conductor, double only is applicable to down phase conductor, and equipotential personnel overall qualities are had relatively high expectations, be difficult in live line working, popularize in an all-round way application.Method (2) is as long as can customize corresponding insulation ladder firmly in conjunction with tower, all can be suitable for for most of tower, thereby have the scope of application wide, enter advantages such as the electric field process is convenient, but exist also that weight is big, amount of deflection big, the overlap joint size is big and the general defective of Work tool inconvenience during the three-phase operation.Method (3) has advantages such as the tower of use is various, the scope of application is wide, but because the characteristic of insulation hanging basket itself, left and right sides rope has limited equipotential personnel's working space, is unfavorable for that the operating personnel enters equipotential rapidly.
Summary of the invention
To be solved in the utility model is the above-mentioned defective that prior art exists, and aims to provide a kind of novel equipotential ladder, adopts simple structure to realize delivery fast.
The technical scheme that addresses the above problem employing is: the equipotential ladder comprises the mobile jib of vertical setting it is characterized in that the top of described mobile jib is provided with suspension ring that the middle part of described mobile jib and bottom are respectively arranged with the first horizontal ladder and second horizontal terraced.
Equipotential ladder of the present utility model, during use, operating personnel's both hands are embraced mobile jib, both legs bridge on the first horizontal ladder, and both feet are shelved on the second horizontal ladder, and the equipotential ladder that will be loaded with operating personnel by the insulation rope is transported to operation place, because equipotential ladder of the present utility model adopts hard material to make, operating personnel put forth effort and borrow power easily, can catch live wire fast near high potential the time, and be transferred on the lead rapidly.Because special " scholar " of the present utility model font structure makes operating personnel's both legs stressed evenly, be difficult for producing common problems such as tired and big legs become numb simultaneously, reduced operating personnel's operation intensity, improved the fail safe of operation.Thereby, the utlity model has that Work tool is simple, execute-in-place is convenient, the equal potential working personnel enter outstanding advantages such as electric field process smoothness.
According to further improvement of the utility model, the top of described mobile jib also is provided with the 3rd horizontal ladder.Operating personnel can directly catch both hands the 3rd horizontal ladder, make in the process of transporting more stablely, and because both hands are open-shaped, thereby can catch live wire quickly.
According to the utility model, described mobile jib and each horizontal ladder adopt insulating epoxy system, and described suspension ring adopt stainless steel; Described mobile jib top set metal cap, described first metal cap and suspension ring welding; Junction between described mobile jib and each the horizontal ladder all is set with metal cap, and rivets by pin.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is an another kind of execution mode of the present utility model.
Fig. 4 adopts job state figure of the present utility model.
Embodiment
With reference to Fig. 1,2, equipotential ladder of the present utility model comprises the mobile jib 2 of vertical setting, and the top of described mobile jib 2 is provided with suspension ring 1, and the middle part of described mobile jib 2 and bottom are respectively arranged with first horizontal the ladder 5 and second horizontal ladder 7.Described mobile jib 2 and each horizontal ladder adopt insulating epoxy system, and described suspension ring 1 adopt stainless steel.Described mobile jib 2 top set metal caps 2, described first metal cap 2 and suspension ring 1 welding.Junction between the described mobile jib 2 and the first horizontal ladder 5 is set with metal cap 4, and by pin 9 riveted joints.Junction between the described mobile jib 2 and the second horizontal ladder 7 is set with metal cap 6, and by pin 8 riveted joints.
With reference to Fig. 3, another kind of execution mode of the present utility model is the improvement on Fig. 1-2 execution mode basis, is that with the execution mode difference of Fig. 1-2 the top of described mobile jib 2 also is provided with the 3rd horizontal ladder 10, and all the other structures are identical with Fig. 1-2 execution mode.
With reference to Fig. 4, the course of work of the present utility model is as follows: operating personnel's both hands are embraced mobile jib 3, both legs bridge on the first horizontal ladder 5, both feet are shelved on the second horizontal ladder 7, the equipotential ladder that will be loaded with operating personnel by insulation rope 14 is transported to live wire 11 from the cross-arm 13 of iron tower 12, it is embraced and can operate arriving live wire 11 back operating personnel.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection range of the present utility model.
