Abstract
A falling-preventing personal safety appliance used for the overall process of line repair and pole climbing comprises a c-shaped falling-preventing pothook 2 with a limiting function, a c-shaped sealing pothook 3, a trapezoid spring 1 and a safety rope connecting pile, wherein the front portion and the back portion of the left side of the c-shaped falling-preventing pothook 2 with the limiting function are respectively provided with a left baffle 4 inwards, the front portion and the back portion of the right side of the c-shaped falling-preventing pothook 2 with the limiting function are respectively provided with a right baffle 5 inwards, the c-shaped sealing pothook 3 is installed inside the left baffles and the right baffles of the c-shaped falling-preventing pothook 2 with the limiting function in a sleeved mode, and the trapezoid spring 1 is installed between the upper end of the c-shaped falling-preventing pothook 2 with the limiting function and the top of the c-shaped sealing pothook 3. The two overlapped c-shaped pothooks are utilized to achieve opening and closing of the pothooks through linkage of the spring, a person climbing up and down a pole tower is prevented from falling off a high position and can be effectively prevented from falling off the pole tower due to hand slipping in the grabbing process, it is ensured that the person is hung on glide tacks constantly and reliably, and safety in the climbing process is guaranteed. The falling-preventing personal safety appliance used for the overall process of line repair and pole climbing is developed based on the stress features of action principles when people climb poles, and is light in weight, low in cost and high in efficiency.
Description
Technical field
The utility model relates to 35-220kV maintenance of overhead transmission line and steps on bar overall process fall arrest personal security apparatus.
Background technology
Along with the raising of people's living standard, the continuous increase of electricity needs, the fast development of power grid construction paces, maintenance workload is constantly soaring, the requirement of raising personnel operating efficiency and work safety stability also improves constantly, and line maintenance is stepped on bar work and be there is no reliable easy fall arrest measure and instrument at present.
Summary of the invention
The purpose of this utility model will solve practical difficulty exactly, the overall process fall arrest personal security apparatus that provides a kind of line maintenance to step on bar, by the c type hook that utilizes two stacks, by spring, link and realize hook switching mouthful, can effectively prevent due to hand grab sliding and from tower high pendant, all the time guarantee that being a bit reliably suspended on pin nails on, the process safety that guarantees to ascend a height is reliable.
The purpose of this utility model is achieved like this: a kind of line maintenance is stepped on the overall process fall arrest personal security apparatus of bar, is characterized in: it mainly comprises with the anti-fall hook 2 of spacing c type, c type sealing hook 3, trapezoidal spring 1, safety rope connection stake; Before and after the left side with the spacing anti-fall hook 2 of c type, be all inwardly provided with right baffle-plate 4, before and after the right with the spacing anti-fall hook 2 of c type, be all inwardly provided with right baffle plate 5; In c type sealing hook 3 left baffle that are set in the spacing anti-fall hook 2 of c type, trapezoidal spring 1 is contained between the upper end and the top of c type sealing hook 3 with the spacing anti-fall hook 2 of c type.
The utility model is linked and is realized hook switching mouthful by spring by the c type hook that utilizes two stacks, realize the anti-high pendant of the person of upper and lower shaft tower, can effectively prevent due to hand grab sliding and from tower high pendant, guarantee that being all the time reliably suspended on pin nails on, guarantee the safety of the process of ascending a height; To utilize human body to step on the anti-fall apparatus of the light-duty little cost-effective rate of individual of the operating principle loading characteristic development of bar process.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks schematic diagram.
Fig. 2 is that schematic diagram is looked on a left side of the present utility model.
Fig. 3 is schematic top plan view of the present utility model.
Fig. 4 is that the utility model is used view.
In figure: 1---trapezoidal spring; 2---with the spacing anti-fall hook of c type; 3---c type sealing hook; 4---right baffle-plate; 5---right baffle plate; 6---pin nail.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3, can find out: the utility model mainly comprises with the anti-fall hook 2 of spacing c type, c type sealing hook 3, trapezoidal spring 1, safety rope connection stake; Before and after the left side with the spacing anti-fall hook 2 of c type, be all inwardly provided with right baffle-plate 4, before and after the right with the spacing anti-fall hook 2 of c type, be all inwardly provided with right baffle plate 5; In c type sealing hook 3 left baffle that are set in the spacing anti-fall hook 2 of c type, trapezoidal spring 1 is contained between the upper end and the top of c type sealing hook 3 with the spacing anti-fall hook 2 of c type.
During use; the anti-fall hook of c type (being with spacing) natural opening under spring action; when people climbs pin nail; thereby the natural downforce that hand is grabbed pin nail moves up c type sealing hook anti-fall c type hook (being with spacing) opening is shut and made it firmly hang over pin to nail on; play anti-falling protection effect, when staff need depart from pin nail, downforce is removed; the anti-fall hook of c type (being with spacing) recovers nature open state under spring action, easily anti-fall hook is taken off from pin nail.The anti-falling protection replacing by the continuous both hands of upper and lower shaft tower is realized the continual anti-falling protection of overall process.
