Abstract

A whole-process anti-falling personal safety appliance for circuit maintenance boarding poles, including a C-shaped anti-falling hook 2 with a limit, a C-shaped sealing hook 3, a trapezoidal spring 1, and a safety rope connecting pile; a C-shaped anti-falling hook with a limit The left side of the hook 2 is provided with a left baffle 4 inwardly, and the right side of the c-type anti-falling hook 2 with a limit is provided with a right baffle 5 inwardly; the c-type sealing hook 3 is set in the c-type with a limit In the left and right baffle plates of type anti-falling hook 2, trapezoidal spring 1 is contained between the upper end of the c-type anti-falling hook 2 of band limit and the top of c-type sealing hook 3. The utility model uses two superimposed c-shaped hooks to realize the opening and closing of the hook through spring linkage, so as to realize the anti-falling of the upper and lower pole towers, and can effectively prevent the high fall from the tower due to slipping hands, and always ensure reliable hanging on the feet. It is nailed to ensure the safety of the climbing process; it is a personal light, low-cost and high-efficiency anti-falling device developed by using the action principle and force characteristics of the human body climbing process.

Description

Fall prevention personal safety equipment for the whole process of line maintenance boarding pole

technical field

The utility model relates to a personal safety appliance for preventing falling during the whole process of climbing a pole for maintenance of a 35-220kV overhead transmission line.

Background technique

With the improvement of people's living standards, the demand for electricity continues to increase, the pace of power grid construction is developing rapidly, the workload of maintenance is constantly increasing, and the requirements for improving personnel work efficiency and work safety and stability are also continuously increasing. Reliable and simple fall prevention measures and tools.

Contents of the invention

The purpose of this utility model is to solve practical difficulties and provide a personal safety appliance for preventing falling during the whole process of climbing poles for line maintenance. By using two superimposed c-shaped hooks to realize the opening and closing of the hook through spring linkage, it can effectively prevent the hand from falling. Grab slippery and fall from the tower, always ensure a reliable suspension on the foot nails, to ensure the safety and reliability of the climbing process.

The purpose of this utility model is achieved in the following way: a whole-process anti-falling personal safety appliance for circuit maintenance boarding poles, which is characterized in that it mainly includes a c-type anti-falling hook 2 with a limit, a c-type sealing hook 3, Trapezoidal spring 1, safety rope connection pile; the left side of the c-type anti-falling hook 2 with a limit is provided with a left baffle 4 inwardly, and the right side of the c-type anti-fall hook 2 with a limit is provided with a front and rear Right baffle 5; c-type sealing hook 3 is set in the left and right baffles of c-type anti-falling hook 2 with limit, trapezoidal spring 1 is contained in the upper end of c-type anti-falling hook 2 with limit and c-type sealing hook 3 between the tops.

The utility model uses two superimposed c-shaped hooks to realize the opening and closing of the hook through spring linkage, so as to realize the anti-falling of the upper and lower towers, and can effectively prevent falling from the tower due to slipping hands, and always ensure reliable hanging on the feet. It is nailed to ensure the safety of the climbing process; it is a personal lightweight, low-cost and high-efficiency anti-falling device developed by using the action principle and force characteristics of the human body climbing process.

Fig. 3 is a schematic top view of the utility model.

Fig. 4 is a schematic view of the utility model in use.

In the figure: 1—trapezoidal spring; 2—c-type anti-drop hook with limit; 3—c-type sealing hook; 4—left baffle; 5—right baffle; 6—foot nail.

Detailed ways

As can be seen from Fig. 1, Fig. 2 and Fig. 3: the utility model mainly comprises a c-type anti-falling hook 2 with a limit, a c-type sealing hook 3, a trapezoidal spring 1, a safety rope connecting pile; a c-type with a limit The left side of the anti-falling hook 2 is provided with a left baffle 4 inwardly, and the right side of the c-type anti-falling hook 2 with a limit is provided with a right baffle 5 inwardly; In the left and right baffle plates of the c-type anti-falling hook 2, the trapezoidal spring 1 is contained between the upper end of the c-type anti-falling hook 2 and the top of the c-type sealing hook 3 with spacing.

When in use, the C-type anti-drop hook (with limit) opens naturally under the action of the spring. When a person climbs the spikes, the natural downward pressure of the nails will move the C-type sealing hook upwards and the C-type anti-fall hook (with limit) the opening is sealed so that it can be firmly hung on the foot nails, which plays the role of anti-fall protection. When the hand needs to leave the foot nails, the downward pressure is released, and the c-type anti-fall hook (with limit) is under the action of the spring Restore the natural opening state, and easily remove the anti-fall hook from the footpeg. Uninterrupted anti-fall protection in the whole process is realized through the anti-fall protection of the upper and lower towers with alternate hands.

Claims (1)

1. line maintenance is stepped on an overall process fall arrest personal security apparatus for bar, it is characterized in that: it mainly comprises with the spacing anti-fall hook of c type, c type sealing hook, trapezoidal spring, safety rope connection stake; Before and after the left side with the spacing anti-fall hook of c type, be all inwardly provided with right baffle-plate, before and after the right with the spacing anti-fall hook of c type, be all inwardly provided with right baffle plate; C type sealing hook sleeve is loaded in the left baffle with the spacing anti-fall hook of c type, and trapezoidal spring is contained between the upper end and the top of c type sealing hook with the spacing anti-fall hook of c type.
