Abstract
A kind of elevator car safety is provided, technical field is elevator car safety.It can be avoided casualties caused by elevator derailedness, safety tongs and limiter of speed fail.The present invention makes elevator safety land using the pressure drag that the enclosure space of carriage lower part generates.Main composition increased blower composition when cannot be guaranteed for the partition around carriage, groove of holding one's breath, reinforcement elevator door, the valve on partition, the larger decrease speed of car mass.
Description
Technical field
The present invention relates to elevator car safeties.
Background technique
At present the main security device of elevator be by limiter of speed and safety tongs, usual ordinary accident occur in safety tongs and
Limiter of speed causes used during elevator falling speed is larger personnel is caused to hurt in the case where failing;Or by inevitable natural calamity feelings
Under condition, casualties caused by lift car derails.
Summary of the invention
It solves the problems, such as:
In order to solve the above problem, the present invention provides a kind of safety device, can effectively avoid casualties.
Technical solution:
To achieve the above objectives, the technical solution adopted by the present invention is that: lift car in addition to doorway three sides be arranged partition, partition
It is arranged from bottom to top from elevator bottom plate, elevator door is reinforced；Partition is contactless with carriage and keeps a lesser distance, every
Groove of holding one's breath is arranged in the corresponding face of plate surface and lift car surface；Valve is set on partition；For the elevator of larger load, bottom
Portion adds Fan Equipment.
Under normal conditions, whole partition valves are opened, and air frees in and out.When there is accident, elevator is with larger speed
Tenesmus, at this time valve closing, lift car and closed partition form approximate confined space in carriage lower part, and elevator drops to sky
Gas generates pressure, pressure drag is formed, so that lift car low speed be made to fall.Because lift car lower air can only be by carriage four
Week escapes with spacer gap, and lift car falling speed and ambient air escape velocity are directly proportional, and the groove drop of holding one's breath added
Low latitude gas flows through speed when passing through gap, and carriage is made to be down to bottom with safe speed.For the elevator of larger load, because of carriage matter
To measure larger, when decrease speed cannot be guaranteed safe speed, blower is arranged in bottom in the present invention, and blower mouth has one-way input valve door,
Air is injected to carriage lower space, to improve the pressure that lower part air pressure generates elevator bottom, reduces elevator lapse rate.
The utility model has the advantages that
In the case where conventional security measures failure, cab interior casualties is avoided.Especially suitable for earthquake areas or by
In the case of inevitable natural calamity, elevator derailedness, limiter of speed and safety tongs failure.
Detailed description of the invention:
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is elevator plan view of the invention.
Fig. 2 is elevator sectional view of the invention.
In figure: 1. lift cars, 2. partitions, 3. reinforce elevator doors, and 4. valves, 5 blowers, 6 hold one's breath groove.
Specific embodiment:
Embodiment one: when lift car 1 drops, systems inspection to used during elevator falling, control valve 4 is closed；After valve 4 is closed, sedan-chair
Approximate confined space is formed at compartment lower part, and elevator tenesmus generates pressure to air, forms pressure drag, lower air can only be by carriage
Surrounding and spacer gap escape, and lift car falling speed and ambient air escape velocity are directly proportional, and air flows through logical when gap
Groove 6 of holding one's breath is crossed, speed is flowed through in reduction, when lift car weight is equal to the power that lower part air pressure generates it, under elevator constant velocity
Drop；The setting height view elevator whole height of partition 2 and demand setting can be with by calculating partition 2 for elevator of less demanding
It does not need to top, with save the cost.
Embodiment two: for big load elevator, by calculating the carriage it cannot be guaranteed that declining with safe speed, systems inspection
To used during elevator falling, control valve 4 is closed；After valve 4 is closed, start blower 5, injects air to carriage lower space, improve electricity
The pressure that terraced lower air generates carriage 1, increases pressure drag, and lower air can only be escaped by carriage surrounding and spacer gap
Out, lift car falling speed and ambient air escape velocity are directly proportional, by groove 6 of holding one's breath when air flows through gap, reduce
Speed is flowed through, when lift car weight is equal to the power that lower part air pressure generates it, elevator constant velocity's decline.
Claims (3)
1. a kind of elevator car safety, it is characterized in that: valvular around the vertically arranged band of lift car from shaft bottom
Partition.
2. elevator car safety according to claim 1, it is characterized in that: partition is contactless with carriage and keeps one smaller
Distance, the setting of baffle surface and lift car surface corresponding face holds one's breath groove.
