Abstract
The utility model relates to an examination and repair protective frame of a knife switch, which belongs to the technical field of safety devices of power supply and distribution. The utility model is used for solving the safety protection problems of the examination and repair and upkeep of 110KV knife switches and is composed of a base and protective rods, wherein a groove is arranged on the base. Plug jacks of the protective rods are arranged on both side walls of the groove, the protective rods are insulating materials and safety ropes are arranged on the protective rods. The protective rods are in the clearance fit with the plug jacks of the protective rods, and the base is fixedly connected with the protective rods. The utility model is designed for the universal mounting structure of the 110KV knife switches and is used as a special examination and repair protective frame for the 110KV knife switches. With the utility model, the regular practice that insulators are used as fixing points of safety belts can be abandoned, safety hazards can be eliminated and accidents can be avoided. The utility model has the advantages of small and portable design, convenient use, portability, simple structure and low cost.
Description
Technical field
The utility model relates to the security tool that a kind of electrician overhauls use, and particularly the outside line electrician ascends a height and overhauls the protection rack special of 110KV disconnecting link, belongs to power supply distribution technical field of safety devices.
Background technology
The distribution line of distribution network is made up of overhead transmission line and cable line because overhead transmission line has low cost, draw materials conveniently, construction easily, easy access and find advantage such as fault point easily and be widely used.Electrical equipment comprises controller switching equipments such as transformer, switch tool, fuse, lightning arrester on the post of overhead distribution, because these equipment are arranged on the electric pole, work such as its installation, maintenance, maintenance all need ascend operation, maintenance worker's security protection work is most important, does not have slightly and very will cause security incident.As the 110KV disconnecting link is visual plant on the overhead distribution, and its daily Maintenance and Repair work is absolutely necessary, after the maintenance worker climbs to a higher point, normally insulator as fixing point, the high-altitude safe band is enclosed within on the insulator, carry out operation then.Hardly realize that this way is containing accident potential, because insulator is a ceramic product, matter is crisp easily broken, the long-term in addition material aging of exposing to the weather, fracture suddenly under extraneous heavy burden, is the way that a kind of ten minutes is taken a risk with it as belt anchorage point, once has the workman to cause the die report of accident of worker because of the insulator fracture when maintenance.Therefore, provide a kind of safe, special protection instrument easily, very important and press for for the maintainer of distribution line.
Summary of the invention
The utility model is used to provide a kind of disconnecting link maintenance protective frame of the 110KV of being exclusively used in disconnecting link maintenance repair maintenance safe in utilization, easy to carry.
The alleged problem of the utility model is that following technical scheme solves:
A kind of disconnecting link maintenance protective frame, its special feature is: it is made up of pedestal 1 and fender rod 5, described pedestal is provided with groove 10, the two side of groove is provided with the fender rod jack, described fender rod is the insulation material, fender rod is provided with safety rope 7, and fender rod and fender rod jack matched in clearance are fixedlyed connected between pedestal and fender rod.
Last disconnecting link maintenance protective frame, described pedestal two adjacent edge frames are provided with clamping screw 3, and the end that clamping screw is positioned at groove is provided with pressure strip 4.
Above-mentioned lock maintenance protective frame, described safety rope end is provided with the collar 8.
Above-mentioned disconnecting link maintenance protective frame, described pedestal is provided with and holds hole 10.
The utility model designs at the general mounting structure of 110KV disconnecting link, and it is used as 110KV disconnecting link maintenance protection rack special, and the maintenance worker carries during operation, it is clamped on the fixedly channel-section steel of 110KV disconnecting link, as belt anchorage point.Adopt the utility model, can abandon, eliminate safe hidden trouble, avoid accident to take place the usual practice of insulator as belt anchorage point.The utility model is made up of pedestal and fender rod for splitting structure, and base part is made by metal material, the fender rod part is made by high-strength insulating material, the results showed and can satisfy requirements stressed and insulation two aspects fully, the design of its small volume and less weight, use is carried all very convenient.In addition, the utility model is simple in structure, is easy to realize that the cost cost is low, and promotional value is arranged very much.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
The label of each parts is expressed as follows in the accompanying drawing: 1. pedestal; 2. check pin; 3. clamping screw; 4. pressure strip; 5. fender rod; 6. nylon wheel; 7. safety rope; 8. the collar; 9. hold the hole; 10. groove.
Embodiment
Referring to Fig. 1, the utility model is made up of pedestal 1 and fender rod 5, and pedestal is made by the metal material with sufficient intensity, and fender rod is made by materials such as high-strength insulating material such as light-duty fiberglass, engineering plastics, and both are detachable.Pedestal is provided with groove 10, is provided with the fender rod jack on the two side of groove, and fender rod is by passing in the hole, and check pin 2 is fixedly connected with both.Fender rod is provided with safety rope 7, and the safety rope end is provided with the collar 8, and is shown in Figure 1, fixes a nylon wheel 6 on the fender rod, and safety rope is wrapped on the nylon wheel.For adapting to the fixedly specification of channel-section steel of different 110KV disconnecting links, the degree of depth of groove and width can be greatly, and pedestal two adjacent edge frames are provided with clamping screw 3, and the end that clamping screw is positioned at groove is provided with pressure strip 4.
Earlier pedestal is stuck in the 110KV disconnecting link when the utility model uses fixedly on the channel-section steel, screws clamping screw, make pressure strip hold channel-section steel tightly.Fender rod is inserted in the fender rod jack again, check pin is inserted, pedestal is fixedlyed connected with fender rod, safety belt passes from the collar of safety rope and buckles snap close and promptly can work then.
For being convenient for carrying, pedestal is provided with and holds hole 9.
After the utility model is made, need carry out shock test, to guarantee requirement of strength.Whether whether preoperation inspection pedestal or fender rod have crackle, connect firmly, should be placed on aeration-drying place after the use and preserve.
