Retractable frame structure of anti-drop net

This creation is about a retractable frame structure, especially a retractable frame structure that incorporates a fall-proof net.

Elevators have become the necessary equipment in many places in modern society. Elevator equipment is installed in homes, shopping malls, medical institutions, schools, etc. It is also because of the accident when riding or repairing the elevator. It is not uncommon for repeated transmissions.

In order to solve the above problems, the manufacturers have installed anti-drop nets at the bottom end of the elevator ladder, and the anti-fall nets are fixed on the walls around the bottom end of the ladder room. However, because the anti-fall nets need to constantly check whether the net body is aging or damaged, it is installed around. It is not easy to repair and replace the wall afterwards, so it is not possible to implement regular inspection after installation of the anti-drop net in most places, and it is still impossible to achieve safety protection. In addition, the elevator equipment installed in each place is of different sizes. Although the traditional anti-fall net can be customized according to the size of the vertical well in the ladder, the size of the anti-fall net is required. However, if it is a large elevator, a large anti-fall net is required, and the elevator is used in the vertical well. Confined space, poor air circulation, and dim light, also affect the construction personnel's construction risk. The traditional size of the anti-drop net is larger, and the difficulty of installation is also increased.

In addition to the frequent occurrence of falling accidents by elevator users and maintenance personnel, according to the statistics of the major occupational disaster inspections conducted by the Labor Committee of the Executive Yuan in the past few years, it shows that among the major occupational disaster types in China in the past decade, they have fallen by falling and rolling disasters. The first one, about 32%, shows that the implementation of the "safety measures for falling disasters" is the top priority.

Therefore, how to solve the above-mentioned lack of the prior art is the subject of research and development that is relevant to those engaged in this industry.

Therefore, in view of the fact that the traditional anti-drop net technology is unfavorable for the maintenance personnel to install and maintain, and can not adapt to the use of the ladder room space of various sizes, and in addition to the elevator ladder room can not be installed in other four-wallless locations, it can not be adapted anytime, anywhere. High functionality of various venues and environments.

The technical means adopted by the present invention to solve the problems of the prior art is to position a plurality of vertical columns in an elevator ladder space, fix a horizontal frame at the top of the vertical column, and set a fall prevention net, a fall prevention net and a horizontal frame. The horizontal frame is fixed by a stretching member, wherein each horizontal bracket is composed of two or more supporting plates, and a plurality of holes are opened at the predetermined spacing of the supporting plates. The upper support plate is vertically overlapped with at least a portion of the length section, and the support plates located at the two or more support plates are aligned with each other above and below the hole position of the length section, and then passed through the lock member. In the hole position, the two or more support plates are joined to conform to the length and width dimensions of the elevator ladder space.

The horizontal bracket is composed of a horizontal portion and a vertical portion.

The locking member is composed of a screw and a nut.

The anti-falling net comprises a plurality of first direction ropes, a plurality of second direction ropes and a plurality of fasteners respectively fastened at intersections of the plurality of first direction ropes and the plurality of second direction ropes.

The fall prevention net includes a plurality of first direction ropes, a plurality of second direction ropes and a plurality of fasteners, and is wound at the intersection with one of the first direction rope and the second direction rope.

In terms of effect, it can be used with the retractable horizontal frame design to match the space and size of various elevators. It can also make maintenance personnel more convenient, convenient and quick to check the net body, and also accidentally fall when repairing the elevator. It can be protected. The telescopic frame structure of the anti-fall net can also be used outside the elevator, such as a construction site or any place where high-altitude work is required, which can effectively prevent the damage caused by a high-altitude fall accident.
