Abstract
Utility model discloses oil buffer for elevators, comprise: screw, rubber pad, spring perch, beam tube circle, PVC canvas, Compress Spring, piston rod, lid, piston, sealed screw, projection, base plate, pipe and oil cylinder, is characterized in that: rubber pad is mounted elastically by screw; PVC canvas is contained in bottom spring perch by beam tube corral, and Compress Spring and piston rod are trapped among centre; Piston rod is installed on Compress Spring inside, and Compress Spring one end contacts the other end with spring perch and contacts with lid.When car or counterweight act on energy disperser, fluid can flow under the effect of the pressure, and fluid flows into oil storage chamber from cylinder cavity by throttling pore, plays buffer action by throttling pore to car or counterweight, there is good cushion characteristic, ensure that the safety of car or counterweight.
Description
Technical field
The utility model relates to elevator safety technical field, particularly relates to a kind of oil buffer for elevators with elevator cushion stop.
Background technology
Energy disperser is to provide the elevator car safety of last a kind of safety guard-safeguard.It is arranged in the well pit of elevator, is positioned at immediately below car and counterweight.When elevator is in motion up or down; due to wire cable rupture, traction friction force, brake sticking brake power is not enough or control system is malfunctioning and surmount terminal stop bottom or top layer time; will by energy disperser buffer action; to avoid lift car or counterweight directly hit the end or rush to summit, the safety of protection passenger and equipment.Spring bumper is after being clashed into, and it makes the kinetic energy of car or counterweight and potential energy be the elastic deformation energy of spring, due to the antagonistic force of spring, car and counterweight is slowed down.But when after spring-compressed to end position, will inevitably rebound.Elastic deformation energy in buffer release process.Car still will rebound to rise to produce and clash into.Velocity of impact is higher, and bounce-back speed is larger.Mainly utilize the damping of flow of liquid, alleviate the impact of car or counterweight, there is good cushion characteristic.
When car or counterweight act on energy disperser, fluid can flow under the effect of the pressure, sometimes even can splash go out, and therefore needs running check oil level, supplements when lacking, and this structure oil consumption is large, and environmental pollution is large, very easily causes safety misadventure when oil level is many.
Summary of the invention
The purpose of this utility model is to provide one can not cause environmental pollution, save oil consumption, and can automatically reset oil buffer for elevators.
Oil buffer for elevators, comprising: screw, rubber pad, spring perch, beam tube circle, PVC canvas, Compress Spring, piston rod, lid, piston, sealed screw, projection, base plate, pipe and oil cylinder, and rubber pad is mounted elastically by screw; PVC canvas is contained in bottom spring perch by beam tube corral, and Compress Spring and piston rod are trapped among centre; Piston rod is installed on Compress Spring inside, and Compress Spring one end contacts the other end with spring perch and contacts with lid.
Described oil storage chamber is made up of the cavity of managing 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 of sealed storage oil pocket.
Advantage of the present utility model and beneficial effect are: when car or counterweight act on energy disperser, fluid can flow under the effect of the pressure, fluid flows into oil storage chamber from cylinder cavity by throttling pore, by throttling pore, buffer action is played to car or counterweight, there is good cushion characteristic, ensure that the safety of car or counterweight.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further, oil buffer for elevators, comprise: screw 1, rubber pad 2, spring perch 3, beam tube circle 4, PVC canvas 5, Compress Spring 6, piston 7 bar, lid 8, piston 9, sealed screw 10, projection 11, base plate 12, pipe 13 and oil cylinder 14, rubber pad 2 is arranged on spring perch 3 by screw 1; PVC canvas 5 is enclosed by beam tube circle 4 and is contained in bottom spring perch 3, and Compress Spring 6 and piston rod 7 are trapped among centre; It is inner that piston rod 7 is installed on Compress Spring 6, and Compress Spring 6 one end contacts the other end and contacts with lid 8 with spring perch 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 connected 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 of sealed storage oil pocket 16.
Oil buffer for elevators, because fluid is all stored in hermetically-sealed construction, can not environment to external world, when oil level is many, can not safety misadventure be caused.
Above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering staff in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
