Description
Technical field
The utility model belongs to building safety field, especially relates to a kind of elevator shaft door opening self-closing protective guard.
Background technology
In high building project construction, the security protection of elevator shaft door opening generally adopts steel pipe to set up temporarily and closes or install sizing protective door, potential safety hazard is more, especially at decorations, erection stage, constructor needs frequent turnover elevator shaft door opening, temporary guard rail, protective door do not recover after using in time, very easily high fall accident occur.
Utility model content
The purpose of this utility model is to provide a kind of elevator shaft door opening self-closing protective guard, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model have employed following technical scheme:
A kind of elevator shaft door opening self-closing protective guard, comprise installing plate, montant and some cross bars, described installing plate evenly offers several installing holes, described installing plate is fixed on elevator shaft door opening lateral wall by expansion bolt and described installing hole, described montant and described installing plate be arranged in parallel, described cross bar comprises fixed end and free end, described cross bar fixed end is rotationally connected by hinged crab-bolt and installing plate, and described cross bar is flexibly connected montant near cross bar free end side by hinged crab-bolt.
Preferably, also comprise foot guard plate, described foot guard plate be positioned at a cross bar of lowest part by being welded and fixed.
Preferably, the thickness of described installing plate is not less than 8mm, and width is not less than 50mm; The number of described installing hole is 2; The diameter of described expansion bolt is not less than 12mm.
Preferably, the quantity of described cross bar is 3, and length is not less than 1500mm.
Preferably, the height of described montant is not less than 1100mm, and the material of described montant is identical with the material of described cross bar.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model adopts articulated structure form, operating personnel manually mentions cross bar free end, unclamp cross bar free end after entering elevator door Jing Dong, the utility model closes automatically under gravity, the problem recovered time-consuming, there is potential safety hazard after avoiding elevator shaft door opening safeguard procedures to remove; Structure is simple, safe and reliable, guarantees the safety of work progress; Can regularization produce, peace is torn open conveniently, reusable, reduces security costs and drops into.
Accompanying drawing explanation
Fig. 1 is the structural representation of cross bar free end of the present utility model when not being raised.
Fig. 2 is the structural representation of cross bar free end of the present utility model when being raised.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of elevator shaft door opening self-closing protective guard, comprise installing plate 1, montant 2 and some cross bars 3, described installing plate 1 evenly offers several installing holes 11, described installing plate 1 is fixed on elevator shaft door opening lateral wall by expansion bolt and described installing hole 11, described montant 2 be arranged in parallel with described installing plate 1, described cross bar 3 comprises fixed end and free end, described cross bar 3 fixed end is rotationally connected with installing plate 1 by hinged crab-bolt 4, and described cross bar 3 is flexibly connected montant 2 near cross bar 3 free end side by hinged crab-bolt 4.
In order to further optimisation technique scheme, also comprise foot guard plate 5, described foot guard plate 5 be positioned at a cross bar 3 of lowest part by being welded and fixed.
In order to further optimisation technique scheme, the thickness of described installing plate 1 is not less than 8mm, and width is not less than 50mm; The number of described installing hole 11 is 2; The diameter of described expansion bolt is not less than 12mm.
In order to further optimisation technique scheme, the quantity of described cross bar 3 is 3, and length is not less than 1500mm.
In order to further optimisation technique scheme, the height of described montant 2 is not less than 1100mm, and the material of described montant 2 is identical with the material of described cross bar 3.
The utility model proposes a kind of elevator shaft door opening self-closing protective guard.The utility model adopts expansion bolt to be arranged on elevator shaft door opening lateral wall, by promoting cross bar 3 free end during unlatching, unclamp free end after personnel enter, automatically close under gravity, the accident stopping to cause because not closing elevator shaft protective equipment in time crashes into elevator hoistways security incident.
The utility model closes under gravity automatically, the problem recovered time-consuming, there is potential safety hazard after avoiding elevator shaft door opening safeguard procedures to remove; Structure is simple, safe and reliable, guarantees the safety of work progress; Can regularization produce, peace is torn open conveniently, reusable, reduces security costs and drops into.
Above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
