Abstract
The utility model provides a kind of construction elevator Terrace prevention door that can automatically close, comprise door and column, described door is double door, and be fixed on the described column of its both sides by hinge, characterized by further comprising spring and limit rope, described spring one end is connected with described door, and the other end is connected with described column, described limit rope two ends are individually fixed on two root posts, and described limit rope is just to described door top.Door and column arrange spring, pushes when personnel pass in and out in lateral, door is closed, without the need to artificial manual-lock automatically due to the effect of spring after pushing open; The effect that after limit rope plays and prevents a resilience, opens outward opens; When construction elevator arrives door correspondence position, touch trigger, make door lock be in opening, when preventing construction elevator from not arriving, door is surprisingly opened.The utility model automatically can be closed and be prevented unexpected unlatching, improves the safety of discharging platform mouth, guarantees not occur falling from high altitude and junk casualty accident at this place.
Description
Technical field
The utility model belongs to construction safety protection field, particularly relates to a kind of construction elevator Terrace prevention door.
Background technology
In recent years, along with the continuous expansion of building operations scale, building structure construction is also more complicated various, variously faces limit, the security incident at hole often occurs, in whole construction industry accident, forget that closing unloading platform protective door occurs that the accident ratio that high falling or junk are hurted sb.'s feelings rises year by year.Therefore, the protection of the unloading platform protective door of highrise building is the most important thing of current job site security protection.But from the actual conditions of current each job site, the protective door of present use is all artificial manual closedowns, if staff lacks a sense of responsibility or the project management protective door that all can cause not in place forgets closedown, thus causes very large hidden danger to safety management in construction site.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of construction elevator Terrace prevention door that can automatically close, comprise door and column, described door is double door, and is fixed on the described column of its both sides by hinge, characterized by further comprising spring and limit rope, described spring one end is connected with described door, the other end is connected with described column, and described limit rope two ends are individually fixed on two root posts, and described limit rope is just to described door top.
Often fan on described column that described door is adjacent and be provided with two described springs.
Described limit rope is wire rope.
Described wire rope is provided with red and white or yellow black alternate warning look.
Be provided with trigger below described door, described trigger is connected with the door lock be positioned at inside described door.
The beneficial effects of the utility model are: on door and column, arrange spring, push when personnel pass in and out in lateral, and door is closed, without the need to artificial manual-lock automatically due to the effect of spring after pushing open; The effect that after limit rope plays and prevents a resilience, opens outward opens; When construction elevator arrives door correspondence position, touch trigger, make door lock be in opening, when preventing construction elevator from not arriving, door is surprisingly opened.The utility model automatically can be closed and be prevented unexpected unlatching, improves the safety of discharging platform mouth, guarantees not occur falling from high altitude and junk casualty accident at this place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side schematic view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, door; 2, column; 3, spring; 4, limit rope; 5, trigger; 6, door lock.
As Fig. 1, shown in 2, double door 1 is fixed on the column 2 of its both sides by hinge, often fan door about 1 and be connected with two springs 3, spring 3 bolt is on door, one end is fastened on the bowl fastener of ricker 2, below door 1 highest point, 5cm place establishes a limit rope 4, limit rope 4 two ends, position are individually fixed on two root posts 2, limit rope 4 is wire rope, wire rope is provided with red and white or yellow black alternate warning look, trigger 5 is provided with below door 1, trigger 5 is connected with the door lock 6 be positioned at inside door 1, door 1 is heavy wall square tube, add steel plate, gauze wire cloth combining form, whole employing welding, steel plate adopts thickness 2mm thin-walled part, size is generally high 190cm, the wide 60-65cm of single door 1, the spring 3 selecting moment of torsion less, make to close in 20-30 second of door 1 after opening completely, to ensure the turnover of personnel, prevent personnel from promoting to be clamped by door 1 when small handcart enters building, also the impact to limit rope 4 when door 1 is closed is reduced.
Trigger 5 has projection towards outer setting, and after construction elevator reaches the position of door 1 correspondence, expression lobes, projection is pressed into trigger 5, and trigger 5 drives the keeper of door lock 6 to move down, and makes door lock 6 be in opening, and door 1 can inwardly be pushed open by personnel.After construction elevator leaves door 1 correspondence position, protruding ejection, trigger 5 drives the keeper of door lock 6 to move up, and makes door lock 6 be in closed condition, prevents the unexpected unlatching of door 1.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
