Abstract
The invention discloses an elevator buffer. The elevator buffer comprises a cylinder body, a plunger, a damping spring and an end cap, wherein the plunger is installed in the cylinder body, the damping spring is installed on the outer side of the plunger, the end cap is arranged on the plunger and fixedly connected with the plunger, the top of the damping spring and the end cap are clamped, and the end cap is provided with a rubber pad. A magnetic valve is installed at one end of the cylinder body, and a hydraulic joint is installed at the other end of the cylinder body and provided with a one-way valve. The magnetic valve is provided with a single-chip microcomputer and a laser speed measurement sensor. The magnetic valve, the single-chip microcomputer and the laser speed measurement sensor are electrically connected in sequence. The elevator buffer is convenient to operate and has a high degree of automation and a good buffer effect.
Description
Technical field
The present invention relates to a kind of buffer of elevator.
Background technology
Elevator is a kind of vertical conveyor with motor as power, equipped with box like gondola, for tier building take advantage of people or
The means of transport of carrying goods.Also there is step, step plate is contained in and continuously runs on crawler belt, be commonly called as escalator or automatic People's Bank of China
Road.Serve the fixed type lifting equipment of regulation floor.Vertical lift elevator has a car, operates at least two row vertical
Or inclination angle be less than between 15 ° of rigid guideway.Car size and version are easy to passenger and are come in and gone out or handling goods.Custom
No matter its type of drive upper, using elevator as vertical transportation means of transport in building general name.Low speed can be divided by speed
Elevator（Below 4 meter per seconds）, express lift 4～12 meter per second) and express elevator (more than 12 meter per seconds).19th century, mid-term started
Existing hydraulic elevator, still applies so far on low-rise building.1852, the E.G. Otis of the U.S. developed rope hoisting
Safety cage.The eighties, driving means have to be improved further, and such as motor is driven by worm-drive and is wound around reel, employing
Balance weight etc..In 19 end of the centurys, employ frictional wheel drive, greatly increase the hoisting depth of elevator.
Buffer of elevator is last link of elevator safety system, breaks down in elevator or plays during accident crouching bottom
The effect of buffering.Thus the people alleviated in elevator or elevator is clashed into from direct.Buffer of elevator is broadly divided into：Oleo cushion
Device, spring buffer and polyurethane bumper absorber, wherein oil buffer are more general due to adapting to various speed tonnage demand applications
Time, spring buffer is used for slower elevators.
Existing buffer of elevator inconvenient operation at present, automaticity is not high, and buffering effect is general.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of easy to operate, high degree of automation, the electricity of good buffer effect
Terraced buffer.
For solving the above problems, the present invention adopts the following technical scheme that：A kind of buffer of elevator, including cylinder body, plunger, subtracts
Shake spring and end cap, described plunger is arranged in cylinder body, and described damping spring is arranged on outside plunger, and described end cap is located at plunger
On, described end cap is fixedly connected with plunger, described damping spring top and end cap clamping, and described end cap is provided with rubber blanket,
Described cylinder body two ends are separately installed with magnetic valve and hydraulic joint, and described hydraulic joint is provided with check valve, described magnetic valve
On be provided with single-chip microcomputer and laser velocimeter sensor, described magnetic valve, single-chip microcomputer and laser velocimeter sensor are electrically connected with successively.
Preferably, described end cap is Titanium Alloy End Cover Part, keep end cover structure intensity high.
Preferably, the rounded setting of described rubber blanket, there is good buffering effect.
Preferably, described rubber blanket is connected with end cap gluing, holding structure firmly installs.
Preferably, described cylinder base is provided with installing plate, keep easy for installation.
Beneficial effects of the present invention are：The laser velocimeter sensor of setting can detect the lapse rate of elevator, by list
Piece machine electromagnetic valve for adjusting, thus adjust the flow that hydraulic pressure in cylinder body has so that easy to operate, high degree of automation；Arrange subtracts
Shake spring and plunger keep good buffer effect；The hydraulic joint of setting is convenient to connect conduit under fluid pressure, injects hydraulic oil toward cylinder body, single
It is prevented from hydraulic oil backflow to valve.

It is separately installed with magnetic valve 6 and hydraulic joint 7, described hydraulic joint 7 is provided with check valve 8, described magnetic valve 6 is provided with
Single-chip microcomputer 9 and laser velocimeter sensor 10, described magnetic valve 6, single-chip microcomputer 9 and laser velocimeter sensor 10 are electrically connected with successively.
Described end cap 4 is Titanium Alloy End Cover Part.
The rounded setting of described rubber blanket 5.
Described rubber blanket 5 is connected with end cap 4 gluing.
Described cylinder body 1 bottom is provided with installing plate 11.
Beneficial effects of the present invention are：The laser velocimeter sensor of setting can detect the lapse rate of elevator, by list
Piece machine electromagnetic valve for adjusting, thus adjust the flow that hydraulic pressure in cylinder body has so that easy to operate, high degree of automation；Arrange subtracts
Shake spring and plunger keep good buffer effect；The hydraulic joint of setting is convenient to connect conduit under fluid pressure, injects hydraulic oil toward cylinder body, single
It is prevented from hydraulic oil backflow to valve.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any
The change or replacement expected without creative work, all should be included within the scope of the present invention.
