One end of the piston post extends into the cylinder body to be connected with the piston, and the other end of the piston post is connected with the supporting board. A pressure relief opening is arranged at the lower portion of the cylinder body. The lifesaving device for elevator falling is reasonable in design, simple in structure, easy to implement, safe and reliable, and lower in production cost.
Description
Technical field
The utility model relates to a kind of used during elevator falling lifesaving appliance that is arranged at the elevator hoistways pit.
Background technology
Elevator is the transportation device of vertical direction in the skyscraper, generally is made up of hoistway and machine room, running part, lifting part, control part, safety device five parts; Hoistway surrounds a finite space that holds elevator cage operation by leg, top board and pit, have the gangway at each stop, machine room is arranged on the top of hoistway, pit generally gos deep into ground, be used to install energy disperser, velocity limiter, steel wire rope stretching device etc., elevator in use, owing to the jacking system et out of order of elevator produces the accident that the elevator case falls generation is arranged by chance also, because the pit of elevator hoistways does not have corresponding shock attenuation device, so in case the elevator case falls, just directly contact with pit, very stiff and demanding, cause personnel's injures and deaths just relatively more serious.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of safety performance height, the used during elevator falling lifesaving appliance of personal casualty in the time of can avoiding the elevator case to fall.
The technical solution of the utility model is as follows: a kind of used during elevator falling lifesaving appliance, it is characterized in that: comprise cylinder body, piston, following cylinder cap, upper cylinder cover, stay bearing plate and piston pillar, the top of described cylinder body is provided with upper cylinder cover, the bottom is provided with down cylinder cap, described piston is positioned at cylinder body, one end of described piston pillar stretches in the cylinder body and is connected with piston, and the other end of described piston pillar connects stay bearing plate, and the bottom of described cylinder body is provided with a pressure relief openings.
Adopt technique scheme, be installed in this lifesaving appliance on the well pit or on the pit of hoistway, dig one and extend hoistway and this device is installed in extends in the hoistway, as long as guarantee when lift car falls, can touch stay bearing plate and move down smoothly.Piston moment moves down when lift car falls, air in the compression cylinder, form the bearing force upwards that grows from weak to strong gradually in the cylinder body below piston, make fall energy decay gradually under the effect of the bearing force that strengthens gradually of the lift car that falls, the speed of falling reduces gradually, and the high pressure gas of compression make pressure gas in time lose bounce-back energy to lift car by the timely release of less pressure relief openings, finally make stopping of elevator safety, to avoid personnel's injures and deaths.
In technique scheme, the position that described piston pillar is close to the upper cylinder cover upper surface is provided with a groove, is provided with the shear-type bayonet lock in this groove, does the time spent not being subjected to external force, described shear-type bayonet lock with the piston shore supports on upper cylinder cover, thereby piston is positioned the top of cylinder body.Do the time spent when being subjected to external force, the shear-type bayonet lock fractures, and the piston pillar moves down.
In technique scheme: be provided with cushion rubber on the upper surface of described stay bearing plate.At first contact the buffering transmission that cushion rubber obtains fall energy when lift car falls, avoid falling lift car and lifesaving appliance form knock-on effect, make huge fall energy pass to the piston pillar through buffering.
In technique scheme: described cushion rubber is made by foam or sponge.
In technique scheme: described cushion rubber is an air bag.
In technique scheme: be provided with support ring between described piston pillar and the upper cylinder cover, be provided with piston ring between described piston and the inboard wall of cylinder block.Support ring plays support, and piston ring plays the effect of support piston and seal compression gas.
In technique scheme: the both sides of described inferior part of the cylinder block are provided with the reinforcement base for supporting.
In technique scheme: be provided with air inlet openings on the described upper cylinder cover.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, safe and reliable, and the productive costs of this lifesaving appliance is also lower.
