Manual hole digging operation safety protective cover

Abstract

The invention belongs to the technical field of design and manufacture of building construction facilities, and particularly discloses a manual hole digging operation safety protective cover which comprises a lifting mechanism. The manual hole digging operation safety protective cover consists of a cylindrical cover body and a cover top, a supporting frame is arranged at the upper end of the coverbody, the cover top is hinged to the cover body through a rotating shaft arranged on the supporting frame, the cover top is formed by two arc panels with large top and small bottom, a pushing rod isarranged on the rotating shaft, and the pushing rod hangs down into the cover body; and the cover body is provided with a crown block, and the crown block is connected with the lifting mechanism arranged outside a protective cover body and used for transporting articles. The manual hole digging operation safety protective cover is suitable for the construction operation protection of manual digging holes and piles such as a narrow site, an uneven site, complicated geology and weak foundation.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of building construction facilities, and specifically discloses a safety shield for manual hole-digging operations, which is suitable for protection of manual-digging piles and other construction operations such as narrow sites, uneven sites, complex geology, and weak foundations. Background technique [0002] In the process of building construction, when manual digging is required, there are many uncertain factors in the working environment. It may be accompanied by unsafe factors such as groundwater, quicksand, harmful gas, electric shock, object strike, falling from a height, collapse of the retaining wall, etc. The operators and inspectors in the hole are out of balance or the lifting equipment is damaged during the process of going up and down the hole and fall; The ground tools, mudstones, steel bars, etc. fell into the well for some reason, as well as the lifting tools in the...

AI Technical Summary

Problems solved by technology

It may be accompanied by unsafe factors such as groundwater, quicksand, harmful gas, electric shock, object strike, falling from a height, collapse of the retaining wall, etc. The operators and inspectors in the hole are out of balance or the lifting equipment is damaged during the process of going up and down the hole and fall; The ground tools, mudstones, steel bars, etc. fell into the well for some reason, as well as the lifting tools in the pile holes, the soil, sand, stones in the hanging basket or the decoupling of the hanging basket, and the broken rope surface. Falling into the bottom of the hole and injuring the personnel at the bottom of the hole. The hole contains poisonous gas or oxygen is thin. It is necessary to work without adequate ventilation and replacement, causing poisoning or suffocation. Because the construction site does not strictly follow the standard wiring, the wiring is not standardized, and the bottom of the hole is illuminated. No low-voltage electricity is used. When the submersible pump pumps water when there is water at the bottom of the hole, the personnel do not leave in time and cause electric shock accidents. These problems have been reported in the practice of manual digging
