Abstract
The utility model provides a hole opening safe protection device, which comprises a fixed plate and a movable plate, wherein a through hole is formed in the center position of the fixing plate; the shape of the movable plate is anastomotic with the through hole, and the movable plate is a little greater than the through hole; a round hole is formed in the center position of the movable plate; a long strip-shaped opening is formed in a position from the round hole to the side edge of the movable plate; and a hook is arranged at a combining part of the long strip-shaped opening and the side edge. The movable plate and the fixed plate are connected through a movable hinge. After the hole opening safe protection device is fixed on a hole opening, the normal construction operation is not influenced; and the effect of preventing the risk of hidden danger caused on construction safety by falling of small soil blocks or other objects into the hole opening can also be achieved. In addition, the hole opening safe protection device has the characteristics that the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to safety protection device for building construction, the safety device in the aperture while relating in particular to a kind of manually digging hole.
Background technology
Safety prevention measure to aperture when current manually digging hole, the general so easy safeguard procedures such as iron plate or steel mesh reinforcement or the covering of bamboo basketry that adopt, adopt in such a way and have some limitations, can only in the time not carrying out borehole construction operation, just can cover.In the time of operation, these overburden all must be removed again, otherwise cannot construction operation.In work progress, because overburden is removed, near small clod aperture or other thing just likely go out to fall from aperture, cause certain potential safety hazard.
Utility model content
Fall in order to solve aperture small clod or other thing in work progress the problem that causes potential safety hazard as aperture, the utility model provides a kind of aperture safety device that does not affect normal construction.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of aperture safety device, comprise fixed head and portable plate, and the center of described fixed head is provided with through hole, shape and the through hole of described portable plate match, and are slightly larger than through hole.Described portable plate center is provided with circular hole, and circular hole is provided with strip opening to portable plate side edge, and described strip opening and side junction are provided with hook; Described portable plate is connected by hinges with fixed head.
Further, the top of described fixed head is provided with guard ring, and described portable plate is connected by hinges with the top of guard ring.
Further, the height of described guard ring is 50 to 100MM.
Further, described fixed head is circular.
Further, described portable plate is on 10cm*10cm welded steel fabric, to cover one deck dense mesh.
Adopt after the technical solution of the utility model, in construction operation process, safety protector is fixed on to aperture, because portable plate is provided with the good strip opening of circular hole.And portable plate can be opened arbitrarily by hinges.Adopt in such a way, can construction operation normally carry out in order, can effectively protect falling of aperture place small clod or other thing again and cause the risk of security incident.It is reliable that safety protector has safety and stability, simple to operation, has the function that can have enough to meet the need use simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred scheme of the utility model is further elaborated:
As Fig. 1, shown in Fig. 2, a kind of aperture safety device, comprises fixed head 1 and portable plate 2, and described fixed head 1 is circular.The top of described fixed head 1 is provided with guard ring 12, and the height of described guard ring 12 is 50 to 100MM.The center of described fixed head 1 is provided with through hole 11, and the shape of described portable plate 2 and through hole 11 match, and are slightly larger than through hole.Described portable plate 2 covers one deck dense mesh on 10cm*10cm welded steel fabric.Described portable plate 2 centers are provided with circular hole 21, and circular hole 21 is provided with strip opening 22 to portable plate 2 side edge; Described strip opening 22 and side junction are provided with hook 23; Described portable plate 2 is connected by hinges 3 with the top of guard ring 12.
Introduce the use of safety protector below, before construction, safety protector is arranged on to aperture place.In the time of construction operation, hook 23 on pull-up portable plate 2, due to the mode that adopts hinges 3 to be connected between portable plate 2 and fixed head 1, can very easily portable plate 2 be started to opposite side, at this moment the working hoisting rope of carrying facility carefully is deep into inside, aperture by the through hole 11 arranging on fixed head 1, pull-up hook covers portable plate on guard ring 12, after covering, lifting line is moved to behind the center of circular hole 21 by the strip opening 22 arranging between side and circular hole 21, can start construction operation, for the object of safe construction, circular hole on portable plate 2 21 can be designed to slightly larger in diameter in the diameter of lifting line.Fixed head 1 top is provided with protection back-up ring 12, can effectively stop that small clod and other thing drop into the object that causes potential safety hazard in aperture accidentally.Portable plate 2 adopts stainless (steel) wire poroid, can observe the situation in aperture by the mesh on portable plate 2.After having constructed, lifting line is moved to the side edge of portable plate 2 through strip opening 22 from the center of circular hole 21, the hook 23 on pull-up portable plate 2, starts portable plate again, and lifting line and facility are pulled out from the through hole of fixed head.
