Abstract
A power transmission line tension current-guide plate bolt fastener comprises a main shaft component and a moving shaft component; one end of the moving shaft component is provided with a through sleeve; the middle part of the moving shaft component is provided with a through groove; an adjusting key is fixed in the through groove through a rivet and is engaged with the through sleeve; the other end of the moving shaft component is connected with a movable pin through a rivet; one end of the main shaft component is connected with a movable pin through a rivet; and the other end of the main shaft component is provided with a connecting head. With the power transmission line tension current-guide plate bolt fastener of the utility model adopted, a traditional equal potential operation mode can be converted into a ground potential operation mode, such that electrified first-aid repair operation can be quickly completed in a labor-saving manner. According to the power transmission line tension current-guide plate bolt fastener of the utility model, an aluminum alloy material is selected to make the power transmission line tension current-guide plate bolt fastener, and therefore, greater portability and flexibility can be realized, and labor intensity can be greatly reduced, and the working time for processing each heat-emitting point is shorted to 0.5 hour, and therefore, first-aid repair work efficiency can be greatly improved; and operators do not need to wear a full set of closed shielding garment in electrified operation, and therefore, potential safety hazards such as heat stroke can be thoroughly eliminated.
Description
[technical field] the utility model relates to electric power overhaul instrument, specifically a kind of power line tension drainage plate bolt tightener.
[background technology], along with the acceleration of industrialization, Development of China's Urbanization, people's level of consumption improves constantly, and rapid growth has been appearred in the demand of electric power energy, and safe and reliable live line working is to guarantee the electric power key of uninterrupted supply continuously.During high temperature high load capacity, the heating of transmission line wire contact is the operating major hidden danger of circuit always, the screening clothing that needs equal potential working personnel to wear a complete set of sealing is rushed to repair, the activity duration of each heat generating spot is 1 hour, not only labour intensity is large in high-temperature operation for a long time, efficiency is low, and operating personnel also there will be the phenomenon of Heat stroke, physical stamina letdown, is unfavorable for eliminating in time circuit hidden danger point.In order to reduce operating risk, to reduce personnel labor intensity, be badly in need of the instrument of a kind of easy and simple to handle, safe fastening strain insulator drainage plate of research and development.
[summary of the invention] the utility model, for the problems referred to above, provides a kind of power line tension drainage plate bolt tightener.
This power line tension drainage plate bolt tightener, comprises spindle element and moving axis part, it is characterized in that, one end of moving axis part is provided with logical heart sleeve, and moving axis part middle part is provided with groove, and adjusting key is fixed in groove by rivet, and with logical heart engage sleeves; The moving axis part other end is connected with removable pin by rivet; One end of spindle element is connected with removable pin by rivet, and the other end of spindle element is provided with connector.
Earth potential working personnel are connected to insulating bar front end by the connector of drainage plate bolt tightener spindle element end, moving axis part sleeve is packed into drainage plate bolt, before and after push away, draw the insulating bar can be by drainage plate bolted, after tested, the torsion of drainage plate bolt tightener can reach standard value 70kN-80kN.
Advantage of the present utility model: 1, use drainage plate bolt tightener, traditional equal potential working mode can be changed into earth potential working mode, laborsavingly complete rapidly again charged repairing operation.2, drainage plate bolt tightener has been selected aluminum alloy material, lighter, flexible, also greatly reduces labour intensity simultaneously, and the activity duration of processing everywhere heat generating spot shortens to 0.5 hour, has greatly improved repairing working efficiency.3, no longer need to wear the screening clothing of a complete set of sealing during operating personnel's high-temperature operation, thoroughly eliminated the potential safety hazards such as Heat stroke.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model
In figure: 1, spindle element, 2, moving axis part, 3, logical heart sleeve, 4, connector, 5, removable pin, 6, rivet, 7, adjusting key, 8, groove.
[embodiment] is described below enforcement of the present utility model below in conjunction with accompanying drawing:
With reference to Fig. 1, one end of moving axis part 2 is provided with logical heart sleeve 3, and moving axis part 2 middle parts are provided with groove 8, and adjusting key 7 is fixed in groove 8 by rivet 6, and meshes with logical heart sleeve 3; Moving axis part 2 other ends are connected with removable pin 5 by rivet 6; One end of spindle element 1 is connected with removable pin 5 by rivet 6, and the other end of spindle element 1 is provided with connector 4, forms the utility model.
