Description

Folding ladder wellhead anti-falling device

Technical Field

The utility model relates to the technical field of sewer well bodies, in particular to a folding type ladder stand well head falling-preventing device.

Background

The sewer is an urban public facility, and refers to a pipeline for discharging sewage and rainwater from a building; but also refers to an underground passage for draining sewage and rainwater in cities, factories or villages. When the well lid is not reset in time, a gap exists on the ground, so that a large potential safety hazard exists. Therefore, we propose a folding ladder wellhead anti-falling device.

Disclosure of Invention

The utility model aims to provide a folding cat ladder wellhead anti-falling device so as to solve the problems in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the folding cat ladder wellhead anti-falling device comprises a well body and a well cover, wherein a folding cat ladder is arranged on the inner wall of the well body and comprises an upper ladder structure and a lower ladder structure, and the upper end of the upper ladder structure is connected to the upper part of the inner wall of the well body through two hinging seats; the lower end of the upper ladder structure is rotationally connected with the upper end of the lower ladder structure, so that the upper ladder structure and the lower ladder structure are folded; a first hook is arranged on the top beam of the upper ladder structure and used for hanging and fixing the folded lower ladder structure; the other side of the inner wall of the well body is provided with a second hook for transversely fixing the folded folding ladder stand at the well mouth.

As a further improvement of the scheme, the length of the upper ladder structure and the lower ladder structure after folding is smaller than the inner diameter of the well body, so that folding can be guaranteed.

As a further improvement of the scheme, a plurality of photosensitive lamps are arranged at the edge of the upper port of the well cover and the upper port of the well body.

As a further improvement of the scheme, the photosensitive lamp is inlaid on the well cover and the well body, and a transparent protective cover is arranged on the surface of the photosensitive lamp.

As a further improvement of the above-mentioned scheme, the photosensitive lamp emits light by solar energy storage; the photosensitive lamp can emit light at night after absorbing and storing solar energy in daytime, and the well lid is lightened, so that the well lid is beautiful and attractive and can play a role in lighting and warning. And the photosensitive lamp is installed in the well lid equally, if the well lid is lost, the effect of prompting can be played, and the workman who also conveniently gets into well lid work at night provides the illumination simultaneously.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model provides a folding cat ladder wellhead anti-falling device, which is characterized in that a folding cat ladder is arranged on the inner wall of a wellhead of a well body, and the folding cat ladder is put down when in use, so that maintenance personnel can conveniently go up and down; when not in use, the folding cat ladder is transversely hung at the wellhead after being folded, and when the manhole cover is moved, the folding cat ladder at the wellhead prevents pedestrians from carelessly falling, so that the protection effect is realized, and the occurrence of dangerous situations in the falling well is avoided.

2. The photosensitive lamps are arranged on the well cover and the well body, so that on one hand, the utility model can add beauty to urban construction; on the other hand, the well lid can play a role in warning when the well lid is lost; yet another aspect may provide illumination for workers working at night into the manhole cover.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

Examples

Referring to fig. 1 and 2, the well head anti-falling device of the folding type ladder comprises a well body 1 and a well cover 2, wherein a folding ladder 3 is arranged on the inner wall of the well body 1, the folding ladder 3 comprises an upper ladder structure 31 and a lower ladder structure 32, and the upper end of the upper ladder structure 31 is connected to the upper part of the inner wall of the well body 1 through two hinging seats 5; the lower end of the upper ladder structure 31 is rotationally connected with the upper end of the lower ladder structure 32, so that the upper ladder structure and the lower ladder structure are folded; the top beam of the upper ladder structure 31 is provided with a first hook 6 for hanging and fixing the folded lower ladder structure 32; the other side of the inner wall of the well body 1 is provided with a second hook 7 for transversely fixing the folded folding cat ladder 3 at a well mouth.
