Abstract

A kind of extended autostairs, increase memory space in the lower section of autostairs, for storing Extensible pedal, Extensible pedal is under the effect of external force, the centre-of gravity shift formed after being extended through operating rope pedal promotes that Extensible pedal is made to slide into pedal shaft position, the pedal for reaching rotating shaft position pedal can be rotated by 90 ° under external force, it is overlapped on the Extensible pedal other end on tank car guardrail, it proposes to hide stow-away arm rest and the locking of tank car guardrail immediately, security platform is formed, the extended autostairs includes operation rope pulley, sliding slot.

Description

Extended autostairs
Technical field extended autostairs
The present invention relates to one kind on railway loading and unloading tank deck on operating personnel, the special equipment of lower tank car.
Background technique
At present in petrochemical plant, the place such as oil depot stores and transports oil plant using Large Oil tank car, and operating personnel passes through peace Autostairs mounted in oil rack two sides enters tank deck and carries out Job Operations, and after completed loading, operating personnel exits tank car, passes through Autostairs, by pedal operation, autostairs automatically resets, thus generally uses this special equipment.Tank car stop position, often Cause with a certain distance from autostairs has from tank car mouth safety barrier, operator is frequently necessary to walking cambered surface position on tank car, week It is abnormally dangerous to enclose no any safeguard protection.
The object of the invention is that providing a kind of extension job platform, behaviour's safety is improved.
The content of present invention
To solve the above-mentioned problems, the present invention provides a kind of extended autostairs, and one is formed between autostairs and tank car guardrail can With folding and unfolding active job platform.
The present invention adopts the following technical scheme:
A kind of extended autostairs increases memory space in the lower section of autostairs, and for storing Extensible pedal, Extensible pedal is outside Under the action of power, the centre-of gravity shift formed after being extended through operating rope pedal promotes that Extensible pedal is made to slide into pedal shaft position It sets, the pedal for reaching rotating shaft position pedal can be rotated by 90 ° under external force, and the Extensible pedal other end is made to be overlapped on tank car It on guardrail, proposes to hide stow-away arm rest and the locking of tank car guardrail immediately, form security platform, the extended autostairs includes behaviour Make rope pulley, sliding slot.
The extended autostairs includes the pulley for reducing friction, power-assisted, locking.
The extended autostairs includes pedal regulating tank, adjustable pedal extension elongation, adaptive act ladder and tank car Different distance between guardrail.
It include the pulley for reducing friction, power-assisted, locking to more preferably improve the safety of extended autostairs.
It advantages of the present invention and has the beneficial effect that
The configuration of the present invention is simple makes full use of existing space and tank car partial condition, realizes operability and peace in practical application Quan Xing provides safeguard the personal safety for improving labourer.
Detailed description of the invention
Fig. 1 is main view of the invention.
Fig. 2 is top view of the invention.
Wherein, 1- Extensible pedal operating rope, 2- original activity ladder rung, 3- Extensible pedal sliding slot and stowed position, 4- extend Pedal, 5- pedal shaft, 6- Extensible pedal linear movement direction, 7- Extensible pedal rotary motion direction, 8- hide stow-away arm rest, 9- pedal regulating tank.
Specific embodiment
As shown, a kind of extended autostairs, usually 4 is hidden in 2 lower part of autostairs, pulls extend when needed Pedal operation rope 1 moves out Extensible pedal 4, when Extensible pedal 4 in place after, centre-of gravity shift makes pedal shaft 5 enter position, dial Dynamic Extensible pedal 4 makes its rotation, and Extensible pedal 4 is another to be overlapped on tank car, proposes to hide handrail 8, is fastened on hiding handrail On tank car guardrail, withdrawal movement is an inverse process.

Claims (5)
