Description

Shock-absorbing device for fall prevention equipped with elastic material The present invention relates to a fall prevention shock absorber equipped with an elastic material, and more specifically, to a fall prevention shock absorber equipped with an elastic material to prevent worker injury by mitigating the impact through a first safety plate made of rubber, a second safety plate made of high-strength alloy, and a cushioning device supporting the first safety plate and the second safety plate when a worker falls. Generally, a support structure (3), such as a steel tower, is installed on the ground (1) to support power cables or communication cables for transporting high-voltage power from a power plant to a factory, etc. When installing various wires or power cables (2) on a support structure (3) or repairing equipment due to external factors such as lightning, a worker climbs onto the support structure (3) to carry out the work. At this time, protective devices are applied during the work process to prevent workers from falling or the falling of power distribution equipment or wires installed on support structures. In the past, safety platforms (4) or safety belts were used as protective devices, but because the working space of the support structure (3) was narrow, accidents in which a worker fell from the support structure continued to occur frequently due to reasons such as the worker slipping on the safety platform (4) installed on the support structure (3) or carelessly wearing the safety belt. Although protective nets are installed on support structures to prevent such fall accidents, existing protective nets have the problem that the installation and dismantling processes are complex and time-consuming because each component is assembled individually to the support structure. The background technology related to this is disclosed in Korean Registered Patent Publication No. 10-1205611 (Registered on November 21, 2012, Title of Invention: Safety Net for Utility Pole). Referring to FIG. 1, a power distribution facility (transformer) for power distribution is installed in the support structure (3) where the power cable (2) is installed, and a worker climbs up via the safety platform (4) to perform work in order to repair the power distribution facility. However, in situations such as rain, if the above safety platform is slippery, a worker may easily fall from the power distribution equipment installed on the upper part of the support structure (3) at a predetermined height from the ground (1) due to a mistake and sustain an injury. Figure 1 is a picture showing a footrest bolt installed on a typical power distribution pole. FIG. 2 is a top view of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention. Figure 3 is a cross-sectional view taken along A-A' of Figure 2. FIG. 4 is a schematic cross-sectional view of a shock absorber for fall prevention equipped with an elastic material according to one embodiment of the present invention. FIG. 5 is a figure showing the state in which the upper damper of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention is inserted into the inner side of the lower damper. FIG. 6 is a diagram showing the state in which the switch portion of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention is moved to the inside of the lower damper by an external force. FIG. 7 is an enlarged view of a hydraulic cushioning part of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention. FIG. 8 is an enlarged view of a locking member of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention. FIG. 9 is an enlarged view of the switch portion of a fall prevention shock absorber equipped with an elastic material according to one embodiment of the present invention.
