Technical field
The present invention relates to a kind of lift facility field, specifically a kind of elevator slowly sprung back is filled with hydraulic pressure limit buffer It sets.
Background technology
Elevator buffer device is mounted on elevator shaft bottom, when lift car failure is fallen, can play to the end slow Punching, stop and protective effect reduce harm of the used during elevator falling to the passenger in lift car in order to avoid car directly hits bottom.Now Buffer unit applied to elevator is usually spring buffer, although spring buffer can quickly absorb Impact energy, its Bounce is big, the injury that elastic potential energy quick release may be brought to passenger again, therefore is badly in need of a kind of energy slow release of design The elevator limit buffer equipment of elastic potential energy.
Invention content
The purpose of the present invention is to provide a kind of elevator slowly sprung back hydraulic pressure limit buffer devices, to solve the above-mentioned back of the body The problem of being proposed in scape technology.
To achieve the above object, the present invention provides the following technical solutions:
A kind of elevator slowly sprung back hydraulic pressure limit buffer device, including pedestal and cylinder body, the pedestal there are two and Gap between it constitutes guide groove;It is provided with lower cover above the pedestal, the lower cover upper end is fixedly installed cylinder body, described Cylinder body upper end is opening and is detachably equipped with upper cover;It is provided with horizontally disposed head-on collision seat, the head-on collision above the cylinder body Seat upper end is provided with outer cushion pad;The head-on collision seat lower end is provided with piston rod, and the piston rod sequentially passes through upper cover and lower cover It extends in guide groove, and is connect with the block in guide groove;It is provided with buffer spring, institute between head-on collision seat and the upper cover Buffer spring is stated to be set in outside piston rod;Lower buffer spring, the lower buffer spring are provided between the block and lower cover It is set in outside piston rod;It is provided with the piston being adapted to cylinder interior on piston rod in the cylinder body, the piston is by cylinder body It is separated into epicoele and cavity of resorption, the epicoele and lower intracavitary are each filled with hydraulic oil;Be provided on the piston multiple connection epicoeles and The oil-through hole of cavity of resorption, the oil-through hole upper end are provided with the check valve of downlink unlatching;Setting in piston rod at the piston There are vertical pressure ports, the pressure ports to be connected to cavity of resorption by regulator hole, the pressure ports by damping hole with it is upper Chamber is connected to;The damping hole lower end is provided with the sliding slot arranged vertically, and matching unidirectional damping is provided in the sliding slot Block, the unidirectional damping block are connected by resetting spring with sliding slot bottom, and the unidirectional damping block upper end extends in damping hole And there are gaps with damping hole upper wall;The unidirectional damping block is rectangular cylindrical, and the upper end is arranged towards pressure ports side There is 45 ° of inclined surface.
As a further solution of the present invention:It is provided with sealing ring on the contact surface of the upper cover and lower cover and piston rod.
As further scheme of the invention:It is provided with sealing ring on the contact surface of the upper cover and cylinder interior.
As further scheme of the invention:It is both provided with sealing on the piston and the contact surface of piston rod and cylinder body Circle.
As further scheme of the invention:The threaded hole for installation is provided on the pedestal.
Compared with prior art, the beneficial effects of the invention are as follows:When colliding downlink, the upper buffer spring of head-on collision seat compression simultaneously makes Piston rod downlink to drive block downlink, and then stretches lower buffer spring, while piston also moves down, due to check valve Setting, the hydraulic oil of cavity of resorption largely quickly can enter epicoele from oil-through hole, therefore be obtained in car drop event dynamic It can be consumed at a reasonable time by the absorption of outer cushion pad, upper buffer spring and lower buffer spring in move distance, to exempt from Car is removed or alleviates to fall to injury caused by occupants;In addition there is section hydraulic oil can be through regulator hole, pressure ports Enter epicoele from damping hole, since unidirectional damping block upper end is provided with towards pressure ports side 45 ° of inclined surface, hydraulic pressure Oil has it downward active force, to overcome resetting spring (its design resistance is smaller) that unidirectional damping block is pressed into sliding slot It is interior, remove the flow resistance that unidirectional damping block forms hydraulic oil in damping hole.
And after colliding to pole, upper buffer spring and lower buffer spring release elastic potential energy drive piston rod uplink, this When closed check valve, the hydraulic oil of epicoele cannot enter cavity of resorption by oil-through hole, be only capable of out of damping hole above unidirectional damping block Gap location flow into pressure ports, and enter cavity of resorption from regulator hole, to make flow resistance increase, the rebound of the limit buffer device made What is become is slow, avoids the secondary injury that elastic potential energy quick release may be brought to passenger again.
In conclusion the utility model is reasonable in design, pass through hydraulic oil in upper buffer spring, lower buffer spring and cylinder body Triple role realizes the limit buffer in rational time and move distance;Have simultaneously and can effectively slow down in rebound anti- Bullet avoids the secondary injury that elastic potential energy quick release may be brought to passenger again.
