Abstract
The invention discloses a kind of elevator cushion system with reduction damping, including Buffer Unit and reduction damper assembly；Buffer Unit is used for preventing elevator car rigid touch bottom；The piston rod that reduction damper assembly is included cylinder body, damping piston and is fixedly connected with damping piston, piston rod are engaged between rebound stroke with Buffer Unit after Buffer Unit is compressed by elevator car, form reduction damping to Buffer Unit by damping piston；The present invention bottoms out buffering in car and terminates the speed that the engagement of pre reduction damper assembly is played a part of to limit resilience, due to reducing the presence of damper assembly, the cushion stroke and coefficient of elasticity of Buffer Unit can also be increased, thus the realization buffering that more can be relaxed, quick resilience is avoided using reduction damping after buffering, it is ensured that final buffering effect；Avoid because buffer spring coefficient of elasticity is excessive or the long and caused secondary security incident for causing that rebounds of compression travel.
Description
Technical field
The present invention relates to a kind of special safety equipment system, special type is related to the security system that a kind of cage type elevator is bottomed out.
Background technology
Cage type elevator is a kind of vehicles for solving vertical transport, is closely connected with daily life；Existing
Cage type elevator is mainly made up of traction machine, switch board, car, guide rail etc., realizes more rapidly uplink and downlink；In order to realize
Uplink and downlink simultaneously install relevant device, building or other using where cage type elevator can type of construction elevators hoistway, with reality
Existing trouble-free operation.
By mechanical force traction, the uplink and downlink of cage type elevator typically realize that structure is complex, due to use environment,
The problems such as cycle and ageing equipment, quality, drop in the case of causing lift car without constraint or finite constraint, tool
There is more serious safety problem.In prior art, in order to solve by car rigid touch bottom (directly dropping to shaft bottom) to taking advantage of
Seated user causes serious danger, arranges buffer unit in shaft bottom；For express elevator buffer unit is hydraulic cushion, for
Slower elevators then typically using buffer spring structure, and so consider mainly the coefficient of elasticity of spring, stroke and car it
Between relation, if elastic force is excessive, larger bounce can be carried out, cause bigger injury, therefore, express elevator then can not
Using the spring that coefficient of elasticity is larger；And in fact, for express elevator, due to speed, and action of gravity is added, liquid
The buffering of pressure buffering has more slowly, can still produce more serious rigid collision, so as to cause the accident.
Accordingly, it would be desirable to be improved to existing elevator cushion construction, it is suitable to all cage type elevators and uses, in elevator accident
When bottoming out, ensure that gentle, gradual compression buffering and return, it is to avoid because the coefficient of elasticity of buffer spring excessive or
The long and caused secondary security incident for causing that rebounds of compression travel.
Content of the invention
In view of this, it is an object of the invention to provide a kind of elevator cushion system with reduction damping, is suitable to all van-types
Elevator is used, and when elevator accident is bottomed out, ensure that gentle, gradual compression buffering and return, it is to avoid because buffering elastic
The coefficient of elasticity of spring is excessive or the long and caused secondary security incident for causing that rebounds of compression travel.
The elevator cushion system with reduction damping of the present invention, including Buffer Unit and reduction damper assembly；
The Buffer Unit is fixedly installed on elevator bottom to be used for preventing elevator car rigid touch bottom；
The piston rod that the reduction damper assembly is included cylinder body, damping piston and is fixedly connected with damping piston, the work
Stopper rod is engaged between rebound stroke with Buffer Unit after Buffer Unit is compressed by elevator car, by damping piston to buffering group
Part forms reduction damping.
Further, buffer spring on the basis of the Buffer Unit includes being arranged at and it is supported in slow at the top of buffer spring
Punching, the buffer board is just to elevator car bottom；
Further, relative with piston rod be provided with the buffer board fairlead and for engage with piston rod reduction resistance
Buddhist nun's power fastener, the fairlead by can axially directed in the way of be coated at piston rod, the reduction damping force fastener is slow
Rush spring and be compressed between rebound stroke by elevator car and engage with piston rod, the piston normality is close to cylinder base；
Further, reduction damping force fastener be by can along piston rod radially wobble in the way of be articulated with connecing on buffer board
Close bar, engagement bar lower end is provided with the engagement boss for extending internally, be provided with the piston rod for after engagement bar is descending with connect
Close the engagement groove that boss forms hasp；The fairlead is provided with the groove that at least can be used for radial through engagement boss；
Further, engagement bar passes through gravity vertically downward, and engagement boss extends inward into fairlead extended distance to be made to connect
Close boss inner end and can extend into engagement groove；It is used for by the groove for engaging boss in the tangential of fairlead on the fairlead
To engaging boss shape into spacing.
Further, the engagement boss lower surface is the acclivitous inclined-plane of ecto-entad, and the piston rod top is cone
Platform structure；
Further, the engagement groove is the cannelure around piston rod；
Further, the axial location of boss is engaged when the lower edge of the engagement groove is less than buffer spring limited compression.
Beneficial effects of the present invention：The elevator cushion system with reduction damping of the present invention, using buffering spring component
The structure combined with reduction damper assembly, is bottomed out buffering end pre reduction damper assembly engagement in car and plays restriction resilience
The effect of speed, it is ensured that gentle resilience, and downstream buffer is realized using Buffer Unit, due to reducing the presence of damper assembly,
The cushion stroke and coefficient of elasticity of Buffer Unit can also be increased, thus the realization that more can be relaxed is buffered, using reduction after buffering
Damping avoids quick resilience, it is ensured that final buffering effect；Therefore, the structure is suitable to all cage type elevators uses, in elevator thing
Therefore when bottoming out, ensure that gentle, gradual compression buffering and return, it is to avoid because the coefficient of elasticity of buffer spring excessive or
The long and caused secondary security incident for causing that rebounds of person's compression travel.
