Abstract
A kind of self-locking safety door, including：Top bearing pin in safety door plane, installed in the out-of-plane bottom bearing pin of safety door, wherein, the distance at top bearing pin and safety door edge column center is less than bottom bearing pin center to the distance at safety door door edge column center；And door body can produce different movement locus along along top bearing pin, the rotary course of bottom bearing pin, to strengthen the reply effect of safety door.The present invention utilizes safety door self gravitation effect, can not only realize the auto-lock function of door body, solve the problems, such as the self-locking of safety door；Moreover, efficiently avoid the collision problem between bearing pin and safety door lateral rail column, it is ensured that produce stable restoring force in the case where thrust is minimum；Meanwhile, reduce production and maintenance cost.
Description
Technical field
The present invention relates to safety door, more particularly to a kind of self-locking safety door for oil vapor treatment equipment, belong to ocean
Engineering field.
Background technology
Need that all kinds of oil vapor treatment equipment are installed in offshore oil building course, on structural framing, and oil vapor treatment is set
At standby aisle or equipment operation platform vertical ladder mouthful etc., then need to set convenient and practical safety door.Due to conventional common peace
Air cock does not possess auto-lock function, and it is when in use, it is necessary to which artificial closed safe door, therefore, this common safety door exists certain
Potential safety hazard.Self-locking is carried out to common safety door according to special self-locking tool, then can accordingly increase production and safeguard
Cost.
The content of the invention
It is a primary object of the present invention to overcome the disadvantages mentioned above that prior art is present, and provide a kind of self-locking safety
Door, it utilizes safety door self gravitation effect, can not only realize the auto-lock function of door body, the self-locking for solving safety door is asked
Topic；Moreover, efficiently avoid the collision problem between bearing pin and safety door lateral rail column, it is ensured that in the feelings that thrust is minimum
Stable restoring force is produced under condition；Meanwhile, reduce production and maintenance cost.
The purpose of the present invention is realized by following technical scheme：
A kind of self-locking safety door, it is characterised in that：Including：Top bearing pin in safety door plane, it is arranged on
The out-of-plane bottom bearing pin of safety door, wherein, top bearing pin and the distance at safety door edge column center are less than bottom bearing pin center
To the distance at safety door door edge column center；And door body can produce difference along along top bearing pin, the rotary course of bottom bearing pin
Movement locus, to strengthen the reply effect of safety door.
Connected between the bottom bearing pin and safety door by arc plate；And bottom bearing pin presses close to safety door facade.
The upper pin axle position where the safety door within plane, lower pin axle position outside plane where safety door, and
Lower pin axle position is in the out-of-plane distance of safety door, to produce return action power.
Beneficial effects of the present invention：The present invention is due to using above-mentioned technical proposal, and it utilizes safety door self gravitation effect,
The auto-lock function of door body can not only be realized, the self-locking of safety door is solved the problems, such as；Moreover, efficiently avoid bearing pin and safety
Collision problem between door lateral rail column, it is ensured that produce stable restoring force in the case where thrust is minimum；Meanwhile, reduction
Production and maintenance cost.
Brief description of the drawings
Fig. 1 is structural facades schematic diagram of the present invention.
The close-up schematic view that Fig. 2 is A in Fig. 1.
The close-up schematic view that Fig. 3 is B in Fig. 1.
The diagrammatic cross-section that Fig. 4 is C in Fig. 3.
Major Symbol explanation in figure：
1. top bearing pin, 2. lateral rails, 3. keeper band irons, 4. rubber blankets, 5. bottom bearing pins, 6. arc plates, lower pin
Axle center to safety door door edge column center is apart from L, L1. bottoms bearing pin center to the distance at safety door edge column center, L2.
Lower pin axle position is in the out-of-plane distance of safety door.
Embodiment
As shown in Fig. 1-Fig. 4, the present invention includes：Top bearing pin 1 in safety door plane, installed in safety door
Out-of-plane bottom bearing pin 5, wherein, top bearing pin 1 is less than bottom bearing pin center extremely with safety door edge column center apart from L1
Safety door door edge column center apart from L；And door body can produce difference along along top bearing pin 1, the rotary course of bottom bearing pin 5
Movement locus, to strengthen the reply effect of safety door.
Connected between above-mentioned bottom bearing pin 5 and safety door by arc plate 6, it can be prevented effectively from bearing pin and safety door sidebar
Collision between bar column；Meanwhile, bottom bearing pin 5 presses close to safety door facade, to ensure to produce in the case where thrust is minimum
Stable reply effect.
Where above-mentioned top bearing pin 1 is located at safety door within plane, outside plane where bottom bearing pin 5 is located at safety door,
And lower pin axle position is out-of-plane at L2 in safety door, when it is in order that safety door is opened, its Action of Gravity Field wired-AND gate
Body plane produces certain angle, to produce return action power.
When with hand push safety door, vertical state when safety door by closing completely along top bearing pin 1 and bottom bearing pin 5 by
Gradually Unscrew.Because safety door bottom bearing pin 5 is located on the outside of safety door facade, safety door is in the rotary course of bottom bearing pin 5
Gradually it is displaced outwardly, safety door is produced certain angle of inclination.Now, safety door produces one vertically under self gravitation effect
In the lateral force of own layer.When unclamping safety door, safety door is under lateral force effect along top bearing pin 1 and lower pin
Axle 5 is rotated backward, as safety door is rotated, and safety door line of gravity is gradually reduced with vertical facade angle, lateral force
It is gradually reduced, door body is under effect of inertia, with approximately at the uniform velocity state motion, until door lateral rail 2 and the rubber on keeper band iron 3
Pad 4 is contacted, and safety door closure completely realizes self-locking.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all
It is any simple modification, equivalent variations and the modification made according to the technical spirit of the present invention to above example, still falls within
In the range of technical solution of the present invention.
