Description
Technical field
The present invention relates to a kind of cat ladder, specifically, related to a kind of transmission line of electricity maintenance cat ladder that can the Protection personnel.
Background technology
Along with the development of power industry, people constantly increase the requirement of power industry, wish the electrical power services of qualified voltage quality and uninterrupted power supply, and therefore, electric power first-aid, maintenance become more and more important.In electric power first-aid, maintenance, the repairing of transmission line of electricity and safeguard essential, the repairing of transmission line of electricity and safeguard and mostly to adopt cat ladder, the staff climb the needs repairing by cat ladder or the transmission line of electricity safeguarded on, while using cat ladder, directly the cat ladder upper end is leaned against on transmission line of electricity, when the staff is climbed, have potential safety hazard simultaneously, simultaneously, for the safety of assurance, can complete repairing or maintenance work, inefficiency just need other staff to coordinate.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby provide a kind of design science, transmission line of electricity practical, simple in structure, that use safety and facilitate the staff to overhaul circuit to keep in repair cat ladder.
To achieve these goals, the technical solution adopted in the present invention is: a kind of transmission line of electricity maintenance cat ladder, it comprises a pair of symmetrically arranged montant, many cross bars and safety belt, evenly be fixed with the many described cross bars vertical with described montant between a pair of described montant, a pair of described montant top is respectively arranged with the insulation elastic hook towards the same side, a pair of described montant top is respectively arranged with link, the two ends of described safety belt are articulated in described link, and described montant top is provided with parcel tray.
Based on above-mentioned, described elastic hook is the L-type elastic hook, the corresponding described L-type elastic hook of described montant is provided with stationary links, described stationary links one end and described montant hinge, and the described stationary links other end is connected with described L-type elastic hook bottom with removably.
Based on above-mentioned, described cross bar middle part is provided with anti-skidding projection.
Based on above-mentioned, described safety belt two ends are respectively arranged with seat belt hanger, and described safety belt is articulated on described link by described seat belt hanger.
Based on above-mentioned, described L-type elastic hook bottom is provided with connecting hole, and the described stationary links other end is provided with pin, and described stationary links is connected with the described connecting hole of described L-type elastic hook bottom by described pin.
The relative prior art of the present invention has outstanding substantive distinguishing features and significant progressive, specifically, the present invention is different from traditional cat ladder, it comprises montant, many cross bars and safety belt, a pair of described montant top is respectively arranged with the insulation elastic hook towards the same side, by described insulation elastic hook, the cat ladder body closely is connected with transmission line of electricity, while preventing from climbing, cat ladder slides, simultaneously, increase safety belt, when the staff climbs the maintenance position, protected by safety belt and staff, prevented accident; Described montant top is provided with parcel tray, the convenient maintenance tool of placing; It has advantages of design science, practical, simple in structure, use safety and facilitate the staff to overhaul circuit.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below by the specific embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of transmission line of electricity maintenance cat ladder, it comprises a pair of symmetrically arranged montant 1, many cross bars 2 and safety belt 5, evenly be fixed with the many described cross bars 2 vertical with described montant 1 between a pair of described montant 1, a pair of described montant 1 top is respectively arranged with the insulation elastic hook 3 towards the same side, a pair of described montant 1 top is respectively arranged with link, and the two ends of described safety belt 5 are articulated in described link, and described montant 1 top is provided with parcel tray.
This transmission line of electricity maintenance cat ladder is articulated on transmission line of electricity by insulation elastic hook 3, comparing traditional cat ladder directly is overlapped on transmission line of electricity, it is firm to connect, when the staff climbs, transmission line of electricity maintenance cat ladder can not slide, the staff climbs maintenance during position, uses of seat belts 5 self and this transmission line of electricity maintenance cat ladder to be linked together, and the staff is because of accidental falling in placement.
In order better to overhaul transmission line of electricity, described elastic hook 3 is L-type elastic hooks, the corresponding described L-type elastic hook of described montant 1 is provided with stationary links 4, described stationary links 4 one ends and described montant 1 hinge, described stationary links 4 other ends are connected with described L-type elastic hook bottom with removably; When the staff climbs the maintenance position, stationary links 4 is connected with L-type elastic hook bottom, place this transmission line of electricity maintenance cat ladder and leave transmission line of electricity because of accident, the Protection personal security.
In order to make the climbing of whole transmission line of electricity maintenance cat ladder convenient, described cross bar 2 middle parts are provided with anti-skidding protruding 21, and while placing climbing, staff's sole skids.
For being connected of convenient and safe band and described montant, described safety belt 5 two ends are respectively arranged with seat belt hanger, and described safety belt 5 is articulated on described link by described seat belt hanger.
The present embodiment provides the syndeton of a kind of L-type elastic hook and stationary links, described L-type elastic hook bottom is provided with connecting hole, described stationary links 4 other ends are provided with pin, and described stationary links 4 is connected with the described connecting hole of described L-type elastic hook bottom by described pin.
When this transmission line of electricity maintenance cat ladder is used, first stationary links 4 and described L-type elastic hook are separated, then by described L-type elastic hook, whole cat ladder is mounted on transmission line of electricity, the staff links together self and cat ladder body by safety belt 5 after climbing the maintenance position, then stationary links 4 is connected with the L-type elastic hook, can start service work, simultaneously, described montant 1 top is provided with parcel tray, is convenient to deposit service kit.
