Abstract
The utility model discloses a damping device of an elevator, which relates to a mechanical damping device. The device is arranged between a cage platform and a base, and comprises a lower guide body, a casing body, an upper guide body, a guide sleeve, a damping spring and a connecting plate; the lower guide body is in a disc shape, and a circle of annular dummy clubs are arranged at the middle part of the lower guide body; the casing body is cylindrical and sheathed on the excircle of the dummy clubs; a circle of step rings are arranged on the inner cylinder wall at the upper part of the casing body; the upper guide body is matched with the inner cylinder of the casing body in a sliding way; a small step circle is arranged at the upper part of the upper guide body; the small step circle extends out of the step rings; the damping spring is arranged in the casing body and between the lower guide body and the upper guide body; the connecting plate is fixedly connected on the upper end surface of the small step circle of the upper guide body; and the guide sleeve is arranged between the small step circle and the step rings. A spring plunger performs up-and-down linear motion, ensures the vertical motion of the upper guide body, and prevents tilting motion. The stability of the cage platform load is better guaranteed. The device overcomes the default of the original cage platform damping device, and has the advantages of simple structure, stable guiding, little cage platform shake, self lubricating, abrasion resistance, and prolonged service life.
Description
Technical field
The utility model relates to the shock absorption device of elevator, relates in particular to a kind of mechanical type shock absorption device.
Background technology
Shock attenuation unit generally is rubber damping cushion block and steel plate to be sticked with glue to connect form at the bottom of the past elevator sedan-chair.Sometimes easily come unstuck after this rubber damper and steel plate are bonded at and are given a shock or twist and peel off, and rubber damping piece period of service has been grown and has been prone to drawbacks such as aging, be full of cracks.Simultaneously, this shock attenuation unit does not have guide function, has only solved gravity damping up and down at the bottom of the sedan-chair, and do not resolve peripheral stressed distortion problem, that is to say, when transverse load occurring, elastomeric material directly carries this load, has quickened the aging of rubber in the long-term use, has reduced safety performance.Take rubber damper block buffering device, when number when overload of carrying at the bottom of the sedan-chair, though alarm signal is arranged, do not get rid of and still have excess weight to enter or be detained car, this moment, rubber damper overburden and distortion increased, and the rubber damping cushion block is sustained damage.
Summary of the invention
The utility model provides a kind of and utilized composite material aspect material at above problem, structurally adopts mechanical type, thereby can effectively resist the shock absorption device of the elevator of transverse load.
The technical solution of the utility model is: be arranged at the bottom of the car sedan-chair and between the base, it comprises down director, housing, goes up director, guide pin bushing, damping spring and connecting panel; Described director down is plate-like, and the middle part is provided with a circle annular boss; Described housing is tubular, is sheathed on the described boss cylindrical, and the inner tube wall on described housing top is provided with a circle step circle; The described inner core bearing fit of going up director and described housing, the described director top of going up is the small stair circle, described small stair circle stretches out described step circle; Described damping spring is arranged in the described housing, between following director and the last director; Described connecting panel is fixedly connected on described going up on the round upper surface of director small stair; Described guide pin bushing is located between described small stair circle and the described step circle.
Described damping spring comprises spring one and spring two, and described spring two external diameters make spring two be arranged in the spring one less than the internal diameter of described spring one.
The housing top of the utility model shock attenuation unit studs with the guide pin bushing that adopts the ultra-high molecular weight polyethylene engineering plastics to make, and the guide pin bushing material is the employing engineering plastics that ultra-high molecular weight polyethylene contains molybdenum disulphide.Its purpose is that the guide pin bushing endoporus has preferably intensity and resistance to abrasion, self-lubricating property is preferably arranged.Last director, following director, attaching parts are made with carbon steel.During the utility model is used when the number overload of carrying at the bottom of the sedan-chair, the signal that receives the report for police service, in overload or when continuing to occur loading phenomenon, the attaching parts pressuring spring sinks to shelving on housing and the guide pin bushing on the plane, spring can not bear overload and load.Because the ultra-high molecular weight polyethylene that adopts guide pin bushing contains the engineering plastics of elements such as glass dimension pearl, molybdenum disulphide, makes the existing rigidity of housing, wear-resisting and self-lubricating again to have strengthened service life greatly.The utility model guarantees the perpendicular movement of upper conductor owing to straight-line motion principle of work about the spring plunger that adopts, and has overcome the possibility of banking motion.Guaranteed the stability of sedan-chair bed load preferably.The utility model has overcome the defective of shock attenuation unit at the bottom of original sedan-chair, and the vibration reduction and cushioning apparatus structure is simple at the bottom of this sedan-chair, and guiding is stable, rocks for a short time at the bottom of the sedan-chair, and self-lubricating, wear-resistant has prolonged service life.

The specific embodiment
The utility model as shown in Figure 1, it comprises down director 6, housing 2, goes up director 5, guide pin bushing 4, damping spring 3 and connecting panel 1; Described director 6 down is plate-like, and the middle part is provided with a circle annular boss; Described housing 2 is tubular, is sheathed on the described boss cylindrical, and the inner tube wall on described housing 2 tops is provided with a circle step circle; The described inner core bearing fit of going up director 5 and described housing 2, described director 5 tops of going up are the small stair circle, described small stair circle stretches out described step circle; Described damping spring 3 is arranged in the described housing 2, between following director 6 and the last director 5; Described connecting panel 1 is fixedly connected on described going up on the round upper surface of director 5 small stairs; Described guide pin bushing 4 is located between described small stair circle and the described step circle.
Described damping spring 3 comprises spring one and spring two, and described spring two external diameters make spring two be arranged in the spring one less than the internal diameter of described spring one.
When the utility model is used, shown in Fig. 2,3, after whole assembling is finished, be arranged at the bottom of the sedan-chair of car 7 and base 8 between.Following director 6 is fixedly connected on the base 8, connecting panel 1 with 7 link to each other at the bottom of the sedan-chair; Impact load, when vibrations of vertical direction are arranged, and coil spring (damping spring 3) plays good buffer action; When meeting unbalance loading, transverse load, because the effect of guide pin bushing 4, housing 2,7 can not be offset with respect to base 8 at the bottom of the sedan-chair.
