Abstract
The invention relates to an automatic locking device of a passageway. The automatic locking device comprises a first handrail and a second handrail arranged in a row; a passageway is formed between the first handrail and the second handrail; the automatic locking device of the passageway further comprises a third handrail which is L-shaped; one end of the third handrail is inserted in a tubular hub on the first handrail; the axial direction of the tubular hub and the axial direction of the first handrail form an acute angle in the vertical direction. According to the automatic locking device disclosed by the invention, automatic locking of the passageway is realized by smartly utilizing the gravity action of the handrails; the automatic locking device of the passageway, which is disclosed by the invention, is simple in structure, safe and reliable.
Description
Technical field
The present invention relates to a kind of passage automatic locking apparatus, particularly personnel's passage automatic locking apparatus of walking, belongs to safety technics field.
Background technology
At some equipment especially in altitude plant, in order to prevent that personnel from falling from height in the air, the passage of personnel's walking all needs to install the door that can automatically close or the arresting gear that can automatically close, at present in work high above the ground machinery, conventionally the door that adopts installation automatically to close is realized, and automatically close common employing spring and realize, but this kind of complex structure cost is high, if spring failure can not be realized the function of automatically closing, thereby the potential safety hazard of causing.
Summary of the invention
The object of this invention is to provide the device that a kind of passage automatically locks, a kind of device automatically locking for aerial lift device personnel channel particularly, property simple and reliable for structure is good.
Technical scheme: a kind of passage automatic locking apparatus, comprise the first railing and the second railing that are arranged side by side, between described the first railing and described the second railing, form passage, also comprise third column bar, described third column bar is L shaped, its one end is inserted in the tubular hub on described the first railing, described tubular hub axially with described the first railing be axially in vertical direction acute angle.
Preferably, on the height of the corresponding described third column bar of described the second railing, be provided with L shaped draw-in groove, described third column bar one end when closing is snapped in described L shaped draw-in groove.
Preferably, between described third column bar and described the first railing, being also provided with spring makes described third column bar need to overcome the power of described spring when opening.
Operating principle: have certain angle owing to being arranged on tubular hub and described first railing of described the first railing, described third column bar, under the effect of gravity, oppositely cuts out described passage all the time automatically, so just can avoid personnel to fall from passage.
L shaped draw-in groove is set, can further the free end of described third column bar be stuck in draw-in groove, safer.
Under the effect of described spring, described third column bar need to overcome the power of described spring while opening, more safe and reliable.
Automatically locking of the passage that the present invention realizes by the ingenious effect that utilizes railing gravity, simple in structure, safe and reliable.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention stereogram.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment mono-:
As shown in Figure 1, a kind of passage automatic locking apparatus, comprise the first railing 1 and the second railing 2 that are arranged side by side, between described the first railing 1 and described the second railing 2, form passage 3, also comprise third column bar 4, described third column bar 4 is L shaped, and its one end is inserted in the tubular hub 5 on described the first railing 1, described tubular hub 5 axially with described the first railing 1 be axially in vertical direction acute angle.
On the height of the corresponding described third column bar 4 of described the second railing 2, be provided with L shaped draw-in groove 6, described third column bar 4 one end when closing is snapped in described L shaped draw-in groove 6.
Between described third column bar 4 and described the first railing 1, being also provided with spring 7 makes described third column bar 4 need to overcome the power of described spring 7 when opening.
Operating principle: have certain angle with described the first railing 1 owing to being arranged on the tubular hub 4 of described the first railing 1, described third column bar 4 is under the effect of gravity, all the time automatically described passage 3 is oppositely closed, so just can avoid personnel to fall from passage.
Described L shaped draw-in groove 6 is set, can further the free end of described third column bar 4 be stuck in draw-in groove, safer.
Under the effect of described spring 8, described third column bar 4 need to overcome the power of described spring 8 while opening, more safe and reliable.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
