Abstract
The invention discloses a kind of oil buffer for elevators, including: screw, rubber blanket, spring base, beam tube circle, PVC canvas, compression spring, piston rod, lid, piston, sealed screw, projection, base plate, pipe and oil cylinder, it is characterised in that: rubber blanket is mounted elastically by screw；PVC canvas is contained in bottom spring base by beam tube corral, and compression spring and piston rod are trapped among centre；Piston rod is installed on inside compression spring, and compression spring one end contacts the other end with spring base and contacts with lid.When car or counterweight act on buffer, fluid can flow under the effect of the pressure, and fluid flows into oil storage chamber from cylinder cavity by throttling pore, by throttling pore, car or counterweight is played cushioning effect, there is good shock-absorbing capacity, it is ensured that car or the safety of counterweight.
Description
Technical field
The present invention relates to elevator safety technical field, particularly relate to a kind of a kind of oil buffer for elevators with elevator cushion stop.
Background technology
Buffer is to provide the elevator car safety of last a kind of safeguard protection.It is arranged in the well pit of elevator, is positioned at the underface of car and counterweight.When elevator is in being moved upwardly or downwardly; due to wire cable rupture, traction frictional force, brake sticking brake power is not enough or control system is malfunctioning and when surmounting terminal stop bottom or top layer; will by buffer cushioning effect; to avoid lift car or counterweight directly hit the end or rush to summit, protection passenger and the safety of equipment.Spring buffer is after being clashed into, and it makes car or the kinetic energy of counterweight and potential energy be the elastic deformation energy of spring, due to the counteracting force of spring, makes car and counterweight slow down.But when, after spring-compressed to extreme position, rebounding.Elastic deformation energy in release buffering course.Car is still to bounce-back and rises generation shock.Stroke speed is the highest, and ball rebound velocity is the biggest.Mainly by the damping of liquid flowing, alleviate car or the impact of counterweight, there is good shock-absorbing capacity.
When car or counterweight act on buffer, fluid can flow under the effect of the pressure, the most even can splash go out, it is therefore desirable to running check oil level, supplements when lacking, and this structure oil consumption is big, and environmental pollution is big, easily causes security incident when oil level is many.
Summary of the invention
It is an object of the invention to provide one not result in environmental pollution, save oil consumption, and can automatically reset a kind of oil buffer for elevators.
A kind of oil buffer for elevators, including: screw, rubber blanket, spring base, beam tube circle, PVC canvas, compression spring, piston rod, lid, piston, sealed screw, projection, base plate, pipe and oil cylinder, rubber blanket is mounted elastically by screw；PVC canvas is contained in bottom spring base by beam tube corral, and compression spring and piston rod are trapped among centre；Piston rod is installed on inside compression spring, and compression spring one end contacts the other end with spring base and contacts with lid.
Described oil storage chamber is made up of the cavity managed between oil cylinder, and has throttling pore on oil cylinder.
Described piston rod and piston pass through screw joints.
Described sealed screw and projection are installed in the side of pipe, and sealed screw has the effect sealing oil storage chamber.
Advantages of the present invention and providing the benefit that: when car or counterweight act on buffer, fluid can flow under the effect of the pressure, fluid flows into oil storage chamber from cylinder cavity by throttling pore, by throttling pore, car or counterweight are played cushioning effect, there is good shock-absorbing capacity, it is ensured that car or the safety of counterweight.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further, a kind of oil buffer for elevators, including: screw 1, rubber blanket 2, spring base 3, beam tube circle 4, PVC canvas 5, compression spring 6, piston 7 bar, lid 8, piston 9, sealed screw 10, projection 11, base plate 12, pipe 13 and oil cylinder 14, rubber blanket 2 is arranged on spring base 3 by screw 1；PVC canvas 5 is enclosed by beam tube circle 4 and is contained in bottom spring base 3, and compression spring 6 and piston rod 7 are trapped among centre；It is internal that piston rod 7 is installed on compression spring 6, and compression spring 6 one end contacts the other end and contacts with lid 8 with spring base 3.
Described oil storage chamber 16 is made up of the cavity between pipe 13 and oil cylinder 14, and has throttling pore 17 on oil cylinder 14.
Described piston rod 7 is coupled by screw 1 with piston 9.
Described sealed screw 10 and projection 11 are installed in the side of pipe 13, and sealed screw 10 has the effect sealing oil storage chamber 16.
A kind of oil buffer for elevators, owing to fluid is all stored in sealing structure, will not environment to external world, when oil level is many, do not result in security incident.
Above embodiment is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention determines.
