Abstract
Line maintenance steps on an overall process fall arrest personal security apparatus for bar, comprises the spacing anti-fall hook of c type 2 of band, c type sealing hook 3, trapezoidal spring 1, safety rope connection stake; All inwardly be provided with right baffle-plate 4 before and after the left side with the anti-fall hook 2 of spacing c type, before and after the right with the spacing anti-fall hook of c type 2, be all inwardly provided with right baffle plate 5; C type sealing hook 3 is set in the left baffle of the spacing anti-fall hook 2 of c type of band, and trapezoidal spring 1 is contained in is with the upper end of the spacing anti-fall hook 2 of c type and c type to seal between the top of hook 3.The present invention realizes hook opening and closing mouth by the c type hook utilizing two to superpose by spring linkage, realize the anti-height pendant of the person of upper and lower shaft tower, can effectively prevent due to hand grab sliding and from tower high pendant, ensure that being reliably suspended on pin nails on all the time, ensure the safety of process of ascending a height; It is the anti-fall apparatus utilizing human body to step on the light-duty little cost-effective rate of individual of the operating principle loading characteristic development of bar process.
Description
Technical field
The present invention relates to 35-220kV maintenance of overhead transmission line and step 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 constantly rises, the requirement improving person works's efficiency and work safety stability also improves constantly, and current line maintenance is stepped on bar work and be there is no reliably easy fall arrest measure and instrument.
Summary of the invention
Object of the present invention will solve practical difficulty exactly, the overall process fall arrest personal security apparatus providing a kind of line maintenance to step on bar, the c type hook superposed by utilizing two realizes hook opening and closing mouth by spring linkage, can effectively prevent due to hand grab sliding and from tower high pendant, all the time ensure that being a bit reliably suspended on pin nails on, the process safety that ensures to ascend a height is reliable.
The object of the present invention is achieved like this: a kind of line maintenance steps on the overall process fall arrest personal security apparatus of bar, is characterized in: it mainly comprises the spacing anti-fall hook of c type 2 of band, c type sealing hook 3, trapezoidal spring 1, safety rope connection stake; All inwardly be provided with right baffle-plate 4 before and after the left side with the anti-fall hook 2 of spacing c type, before and after the right with the spacing anti-fall hook of c type 2, be all inwardly provided with right baffle plate 5; C type sealing hook 3 is set in the left baffle of the spacing anti-fall hook 2 of c type of band, and trapezoidal spring 1 is contained in is with the upper end of the spacing anti-fall hook 2 of c type and c type to seal between the top of hook 3.
The present invention realizes hook opening and closing mouth by the c type hook utilizing two to superpose by spring linkage, realize the anti-height pendant of the person of upper and lower shaft tower, can effectively prevent due to hand grab sliding and from tower high pendant, ensure that being reliably suspended on pin nails on all the time, ensure the safety of process of ascending a height; It is the anti-fall apparatus utilizing human body to step on the light-duty little cost-effective rate of individual of the operating principle loading characteristic development of bar process.

Fig. 1 is schematic front view of the present invention.
Fig. 2 is that schematic diagram is looked on a left side of the present invention.
Fig. 3 is schematic top plan view of the present invention.
Fig. 4 is using state schematic diagram of the present invention.
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 is followed closely.
Detailed description of the invention
As can be seen from Fig. 1, Fig. 2, Fig. 3: the present invention mainly comprises the spacing anti-fall hook of c type 2 of band, c type sealing hook 3, trapezoidal spring 1, safety rope connection stake; All inwardly be provided with right baffle-plate 4 before and after the left side with the anti-fall hook 2 of spacing c type, before and after the right with the spacing anti-fall hook of c type 2, be all inwardly provided with right baffle plate 5; C type sealing hook 3 is set in the left baffle of the spacing anti-fall hook 2 of c type of band, and trapezoidal spring 1 is contained in is with the upper end of the spacing anti-fall hook 2 of c type and c type to seal between the top of hook 3.
During use; the anti-fall hook of c type (being with spacing) natural opening under the action of the spring; when people climbs pin nail; c type sealing hook moves up thus is shut by anti-fall for c type hook (being with spacing) opening and makes it firmly hang over pin to nail on by the natural downforce that hand grabs pin nail; 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 the action of the spring, easily anti-fall hook is taken off from pin nail.The anti-falling protection replaced by the continuous both hands of upper and lower shaft tower realizes the continual anti-falling protection of overall process.
