Abstract

The utility model relates to a screw-type household lift, particularly applicable to houses and villas. The device has the advantages of that: 1. no separate elevator shaft is required and the periphery curtain wall can be used as a elevator shaft, so the traditional elevator car is left out, thus largely reducing the cost; 2. the nut and the screw match with each other and an electric motor drive the nut via a belt to enable a L-shaped lifting platform to move up and down; 3. only one driving motor is needed; 4. an emergency device is provided so that emergency release can be performed in the case of power failure, therefore the utility model is an ideal lift for houses and villas. The utility model comprises a periphery curtain wall with a door and four enclosed sides, which is composed of an elevator shaft curtain wall (1) and a sound insulation curtain wall (16), a door system(2), a set of relatively motionless screw (4) and bearing nut(5)that matching with the screw, a non-bearing nut (6) and an upper fixed nut (11), a driving unit (7), an electric motor (8), a screw upper fixing girder (9), a thrust ball bearing(10), a guideway(13), a guide shoe(14) and a pedestal (15). The electrical motor drives the nut (5) via the belt to move up and down along the screw (4) so as to enable the L-shaped lifting platform to move up and down.

Description

The screw home lift

Technical field

The utility model relates to a kind of screw home lift, is particularly suitable for using in family expenses dwelling house and the villa.

Technical background

Prior art has a vertical leading screw is set in hoist trunk, and leading screw cooperates with nut, and nut is fixed on the lift car, and the leading screw rotation makes the car up-and-down movement that is fixed on the nut.Car adopts conventional enclosed construction, and motor is generally wanted two covers up and down, and motor is contained in the outside of hoist trunk.Its shortcoming is to need special building hoistway space; Adopt two cover motors simultaneously, energy consumption is also big.The spiral lift that other has is realized the envelope up-and-down movement by lifting traveling gear/worm propeller, and this is simple in structure, but only is suitable for loading.In a word, still do not have in the prior art: 1, building hoistway that need not be special-purpose, with outer curtain wall directly as hoistway.2, adopt nut and screw rod to cooperatively interact, realize that screw rod [4] is relative static conditions thereby motor moves up and down a lifting table that is the L type by belt drive nut.3, adopt a motor-driven.4, have emergent disposal device, when having a power failure, promptly put the people.

Technology contents

The utility model is intended to fill up the prior art blank, and a kind of screw home lift is provided, and it has: 1, novel structure, exquisite appearance, building hoistway that need not be special-purpose is directly made hoistway with outer curtain wall, and external form is very elegant in appearance, whole terraced compact conformation can make full use of careat; 2, adopt nut and screw rod to cooperatively interact, realize that screw rod [4] is relative static conditions thereby motor moves up and down a lifting table that is the L type by belt drive nut; 3, adopt a motor-driven, have energy-conservation; 4, have emergent disposal device, when having a power failure, promptly put the people; 5, have the low characteristics of simple installation and maintenance expense simultaneously.

Concrete technology contents of the present utility model is: a kind of screw home lift, and it comprises a four sides sealing that is made of hoistway curtain wall [1] and sound insulation curtain wall [16] and hoistway space/outer curtain wall that door is arranged; One door system [2]; One cover is by the screw rod that is relative static conditions [4] and bearing screwed cap with matching [5], non-bearing nut [6] and go up captive nut [11], and fixed beam [9], thrust ball bearing [10], guide rail [13] on the transmission component [7], motor [8], screw rod, leads boots [14], base [15] formation; Motor [8] drives nut [5] by belt and rotates up and down along screw rod [4], thereby drives L type operate lifting platform [3] up-and-down movement; This device also comprises an emergent disposal device [12].Described screw home lift is characterized in that: sound insulation curtain wall [16] adopts aluminium alloy extrusions to connect, and connects admittedly with base [15], guarantees L type operate lifting platform [3] safe operation in this space.L type operate lifting platform [3] is connected with guide rail [13] by leading boots [14]; When elevator normally moved, motor [8] rotated and drives transmission component [7]; Transmission component [7] comprises driving wheel, flower wheel and two cone belt.Described screw home lift, wherein the lower end of screw rod [4] is connected with base [15] by emergent disposal device [12]; The upper end of screw rod [4] is fixing by fixed beam on the screw rod [9]; Fixed beam on the screw rod [9] is used bolt with guide rail [13] again; When elevator normally moved, screw rod [4] was maintained static by emergent disposal device [12].And flower wheel wherein and bearing screwed cap [5] bolt realizes that bearing screwed cap [5] rotates; When having a power failure, emergent disposal device [12] action, emergent disposal device [12] mainly comprises a storage battery, a motor, a cover worm and gear speed-changing mechanism and an associated fitting; Storage battery is powered to motor, and motor rotates screw rod [4] by the worm and gear speed-changing mechanism; Bearing screwed cap [5] is motionless, thereby the people is promptly put in realization when having a power failure.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

Further describe embodiment of the present utility model below in conjunction with accompanying drawing.Described screw home lift, hoistway curtain wall [1] wherein, door system [2] and sound insulation curtain wall [16] can adopt aluminium alloy extrusions to make equally, make the elevator outward appearance have more fineness, and lightweight characteristics.The utility model only adopts a motor, drives nut [5] through belt-driving, thereby makes a simple L type platform [3] that is placed on the nut [5] do the oscilaltion campaign.This design is very scientific and reasonable, has saved the energy and manufacturing cost widely.The utility model has saved traditional car because adopt circumferential closed outer curtain wall to make hoistway, provides cost savings equally widely.The emergent disposal device when having a power failure is also considered in the utility model design, can promptly put the people rapidly during power failure, and the safety of this elevator is also very good.In a word, the screw home lift that the utility model provides is desirable the closing in family expenses dwelling house and villa elevator of people.
