Abstract
The utility model relates to the field of civil engineering construction opening, in particular to a security manhole channel, which comprises an opening, a moving cover plate and a moving handrail, and is characterized in that the moving cover plate comprises a package edge angle steel and a grating plate, one end of the package edge angle steel is connected with a platform beam through a hinge, a handle is arranged on the other side of the package edge angle steel, the moving handrail comprises stand columns, transverse rods and a return rod, one end of the return rod is bent and lapped on the transverse rod which is arranged on the top end of the stand column arranged on one side of a channel, the other end of the return rod is connected with a turning plate, the turning plate is sleeved on the transverse rod which is arranged on the top end of the stand column arranged on the other end of the channel, and a limit plate is arranged on the tail end of the turning plate. Compared with the prior art, the security manhole channel has the beneficial effects that the moving cover plate is small in self weight, saves labor to be turned over, and is safe and convenient to use. The return rod is arranged on the moving handrail, the moving handrail is conveniently turned over when personnel pass through, and the return rod can automatically return after the personnel pass through, thereby preventing safety accidents from happening in the situation that a handrail does not exist and an opening cover plate is not provided with a cover.
Description
Technical field
The utility model relates to field, civil engineering hole, particularly a kind of safety manhole passage.
Background technology
In current civil engineering, when needs arrange manhole on platform, while especially the manhole hole being set in narrow channel width scope, need to arranging on the side, hole of walkway on railing, hole removable cover is set, in current direction, movable railing is set.Wherein removable cover is comprised of steel plate and two flexible handles.Movable railing has two kinds, and a kind of is detachable, and another kind is that steel chain is set between railing post, and all there is the problem of using inconvenient and potential safety hazard in the two.
Summary of the invention
The purpose of this utility model is to provide a kind of safety manhole passage, alleviates the weight of removable cover, and removable cover can be dug, fall; When the people passes through, the cross bar of movable railing can be dug, safe and convenient to use.
For achieving the above object, the utility model adopts following technical scheme to realize:
A kind of safety manhole passage, comprise hole, removable cover and movable railing, and described removable cover comprises top angle and flase floor, and a side of top angle is connected by folding with landing beam, and the opposite side of top angle is provided with handle; Described movable railing comprises column, cross bar and release link, one end bending of release link is detained on the cross bar on the column top that rides over passage one side, the other end of release link is connected with turnover panel, and turnover panel is enclosed within on the cross bar on column top of passage opposite side, and the tail end of turnover panel is provided with limiting plate.
Compared with prior art, the beneficial effects of the utility model are: the removable cover deadweight is little, digs laborsaving, safe and convenient to use.Movable railing is provided with release link, and when personnel pass through, railing is dug conveniently, and after personnel pass through, release link energy self-return, prevent in the situation that do not cover the generation security incident without railing and hole cover plate.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment application state structural representation;
Fig. 2 is movable railing structural representation in the utility model embodiment;
Fig. 3 is removable cover structural representation in the utility model embodiment.
In figure: 1-platform 2-passage 3-removable cover 4-movable railing 5-column 6-cross bar 7-release link 8-turnover panel 9-limiting plate 10-top angle 11-flase floor 12-landing beam 13-folding 14-handle
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Seeing Fig. 1, is a kind of safety manhole channel application of the utility model status architecture schematic diagram, and wherein hole is located in the middle of platform 1 and is arranged in a passage 2, and removable cover 3 covers on hole, and two movable railings 4 are located on passage and divide the both sides that are positioned at hole.
See Fig. 2, movable railing comprises column 5, cross bar 6 and release link 7, one end bending of release link 7 is detained on the cross bar 6 on column 5 tops that ride over passage one side, the other end of release link 7 is connected with turnover panel 8, turnover panel 8 is enclosed within the cross bar 6 ' on the column 5 ' top of passage opposite side and goes up, and the tail end of turnover panel 8 is provided with limiting plate 9.
See Fig. 3, removable cover comprises top angle 10 and flase floor 11, and a side of top angle 10 is connected by folding 13 with landing beam 12, and the opposite side of top angle 10 is provided with handle 14;
When needs by hole from platform up and down to platform time, hold handle 14 removable cover 3 dug; While going up on platform from platform when needs, the removable cover that holds in the palm under platform is dug it.Because removable cover is made of steel grating plate, so it is little to conduct oneself with dignity, dig laborsaving, safe and convenient to use.When personnel need dig release link 7 from passage through out-of-date, after the people passes through, because limiting plate 9 can limit the rotational angle of release link 7, release link 7 continues can automatically fall after upset collision columns.
