But this inspection shaft anti-falling device has the following disadvantages: when people or objects fall into the inspection shaft anti-falling device, the impact force of people or objects will be concentrated in a certain area of the inspection shaft anti-falling device. The anti-falling device causes damage, resulting in a greatly reduced service life of the inspection well anti-falling device; in addition, the position where the inspection shaft anti-falling device is connected to the connecting rope is close to the periphery of the inspection well anti-falling device, and the safety of the inspection shaft anti-falling device Insufficient protection; said manhole fall arrester consumes more material

Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0034] Such as figure 1 As shown, a manhole fall prevention device provided according to the present invention includes a fall protection cover, and the fall protection cover includes a frame 1, a radial protection part 2, a mesh protection part 3 and a support part 4, wherein: the The radial protection member 2 extends outward from the central area surrounded by the frame 1; the support member 4 is arranged on the outer end of the radial protection member 2; the mesh protection member 3 is arranged on ...

The invention provides a falling prevention device for an inspection well. The falling prevention device comprises a falling prevention protection cover; the falling prevention protection cover comprises a frame, radial protection pieces, reticular protection pieces and supporting pieces; the radial protection pieces extend outwards from a central area surrounded by the frame; the supporting pieces are arranged at the outer end parts of the radial protection pieces; and the reticular protection pieces are arranged in hollow areas formed by the frame and the radial protection pieces. The falling prevention device has the following advantages: the falling prevention device is convenient to mount, the impact strength is improved substantially, and the weight is reduced and materials are saved on the condition that the requirement on the use property is met; and after the inspection well is impacted, force can be dispersed effectively, and no centralized stress is generated at the local part of the inspection well.
Description
technical field [0001] The invention relates to the field of inspection well facilities, in particular to a fall prevention device for inspection wells. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Known as the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well mouth, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. [0003] Because the manhole cover has recycling value, the manhole cover is often lost or stolen; in addition, in rainy weather, people usually open the manhole cover to speed up dr...
