Abstract

For solving inspection shaft safety protection problem, the utility model provides a take steel fibre inspection shaft safety device of protection network, it is including installing the steel fibre inspection shaft seat in the inspection shaft drill way, the inspection shaft seat has the round inner edge, and detachable connection has a plurality of couples on the inner edge, is fixed with the safety protection network that can hide the inspection shaft drill way on the couple. The hook comprises a vertical part and a bending part, the vertical part is provided with a blocking edge, a thread is arranged below the blocking edge, the hook is further provided with a nut matched with the thread of the vertical part of the hook, a through hole is formed in the inner edge of the inspection well seat, and the hook penetrates through the through hole and is fixed on the inner edge of the inspection well seat through the nut and the blocking edge in a matched mode. The hooks are arranged along the circumferential direction of the inner edge at equal intervals. The beneficial effects of the utility model reside in that: the safety protection device is arranged on the inspection well seat, so that the occurrence of an event that pedestrians fall into the uncovered inspection well is effectively avoided, and the safety of sewer maintainers is protected; the safety protection net is firm and reliable and is convenient to disassemble and assemble; the hook has reasonable structure and can not fall off.

Description

Steel fibre inspection shaft safety device

Affiliated field

The utility model relates to a kind of safety device, specifically is meant to be used to prevent that the pedestrian from falling into the steel fibre inspection shaft safety device of inspection shaft.

Background technology

Modern city underdrainage pipe network is crisscross, inspection shaft is densely distributed, and inspection shaft is distributed in the residential block with on the big road of visitors flowrate more, present inspection shaft covers big multidigit cast iron quality, stolen easily, the incident that the pedestrian falls into the uncovered inspection shaft happens occasionally, cast iron inspection shaft lid is substituted by steel fiber reinforced concrete manhole top gradually now, and steel fiber reinforced concrete manhole top is because the material cheapness is difficult for stolen, but when sewer overhauls, the inspection shaft lid is removed, and still can cause very big potential safety hazard to the pedestrian, and ground foreign material is fallen into inspection shaft easily, bring personal injury to the maintainer easily, inspection shaft security protection problem needs to be resolved hurrily.

Summary of the invention

In order to solve inspection shaft security protection problem, the utility model provides a kind of steel fibre inspection shaft safety device with protective screening.

The technical solution adopted in the utility model is:

A kind of steel fibre inspection shaft safety device comprises the steel fibre inspection shaft seat that is installed in the inspection shaft aperture, and described inspection shaft seat has a circle inner edge, removablely on the inner edge is connected with some hooks, is fixed with the safety guard net that the inspection shaft aperture can be covered on the hook.

Hook comprises vertical portion and kink, the vertical portion has the retaining edge, and retaining edge below is provided with screw thread, and hook also is provided with and links up with the nut of vertical portion threaded engagement, inspection shaft seat inner edge is provided with through hole, and hook passes through hole and is fixed on the inspection shaft seat inner edge by nut and the cooperation of retaining edge.

Described hook is arranged along inner edge is circumferentially equidistant.

Described safety guard net is worked out by nylon rope, and the edge nettle can be fastened with the hook kink.

The beneficial effects of the utility model are: on the inspection shaft seat safety device is set, effectively avoids the pedestrian to fall into the generation of uncovered inspection shaft incident and protection sewer maintainer's safety; Solid and reliable, the easy accessibility of safety guard net; Hook structure is reasonable, can not come off.
