Description

The small-sized elevator of torch two controls

Technical field

The utility model relates to the small-sized elevator of a kind of torch two controls, is a kind of ball wire rod-type home lift, belongs to the dumbwaiter class.

Background technology

Along with the raising of social senilization and social civilization degree, people are also increasing to the demand of small-sized elevator.General elevator is the traction-type structure, and this elevator needs mini machine room and easy control cabin/cabinet at least, is applicable to the carrying in building mostly, for low-rise building/villa and public place and be not suitable for.Also have some small-sized elevators to use common screw mandrel and winch form, energy consumption is big during operation, noise is big, driving efficiency is low.Though existing elevator is provided with the function of saving oneself, only at this special status that has a power failure, when circuit breaks down, defencive function will lose efficacy, and have very big potential safety hazard.

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 generally needs two covers up and down, and motor is contained in the outside of hoist trunk.The shortcoming of this leading screw ladder is to need special building hoistway space, adopts two cover motors simultaneously, and it is big that energy consumption is also wanted relatively.Other has a kind of spiral lift, and by the up-and-down movement of lifting traveling gear/worm propeller realization envelope, this is simple in structure, but can only be applicable to loading.

The Chinese patent of the applicant one subordinate company application, the patent No.: 200620103088.0, " screw home lift ", overcome the shortcoming of above-mentioned prior art, it adopts outer curtain wall directly to make hoistway, use nut and screw rod to cooperatively interact, and only drive with a motor, the lifting table up-and-down movement that motor is the L type by belt drive nut lifting one realizes that this elevator is provided with emergent disposal device in addition, have energy-conservation, novel structure, exquisite appearance, building hoistway that need not be special-purpose, aesthetic in appearance generous, whole terraced compact conformation, can utilize careat fully, advantage such as simple installation and maintenance expense are low; But do not have manual function in this application.

In addition, the patent of two pieces of electric and hands, two control home lift aspects is arranged also, but different with the application.

Summary of the invention

The purpose of this utility model is to fill up the prior art blank, provide a kind of later-model torch two controls small-sized elevator, mainly be to the technological improvement of above-mentioned screw home lift and replenish, thereby a kind of novel small-sized elevator unique, that have manual and electronic dual occupation mode is provided.It has adopted the higher ball screw auxiliary driving of driving efficiency, special guide rail, new fixed sturcture, make complete machine have novel structure, exquisite appearance, hoistway specially can extensively be applied to electricity neatly or not have under electricity and the non-electric situation blocked operation neatly.

Concrete technology contents of the present utility model is: the small-sized elevator of a kind of torch two controls is characterized in that: comprise

One leg, described leg are directly made elevator hoistways and sound insulation curtain wall,

One manned formation, described manned is fixed on the ball nut, lifting in leg,

One screw mandrel formula electric transmission, described lead screw transmission mechanism comprises static relatively ball screw and the ball nut that cooperates with it, be commonly referred to as the rolling lead screw auxiliary driving, and the support of transmission component, with drive the rotation of worm reduction box by motor by coupler, and the upper holder of ball screw and lower fixed frame, setting nut, driving gear and ring gear constitute:

One manual control assembly, described manual control assembly comprises handwheel/handle, driving pulley, passive belt wheel, bearing seat, worm reduction box and handwheel erecting frame:

Wherein: adjust the setting accuracy that predetermincd tension guarantees ball screw by setting nut;

Handwheel is installed in handwheel/handle and is installed on the handwheel erecting frame, can be fixed or movable formula and install.

The utility model is when the needs electric operation, and handwheel is turned right and pushed away, and the spline fitted between driving pulley and handwheel is inoperative, that is to say, handwheel/handle and driving pulley are disengaged condition, and handwheel did not rotate when the assurance elevator normally moved up and down;

And when needs are manually controlled, pull out handwheel/handle, spline fitted between driving pulley and handwheel works, make handwheel/handle drive the driving pulley running, thereby driving pulley drives passive belt wheel and rotates the rotation of drive worm reduction box, the ring gear that the driving gear on the output shaft drives on the ball nut under the worm reduction box is rotated, thereby ball nut is rotated, realize manned oscilaltion.

The utility model compared with prior art has following good effect:

1, very scientific and reasonable, the novel structure of design, do not need special hoistway, manually can save the energy and manufacturing cost greatly.

2, owing to adopt rolling lead screw auxiliary driving and motor to drive ball nut, increased line slideway, thereby guaranteed the traveling comfort up and down and the safety of manned platform effectively.

3, this device design-calculated rotates handwheel and drives manually operation of ball nut rotation realization again by driving worm reduction box, and design has the latching characteristics of worm reduction box, ball nut can not be reversed, guaranteed manually light, safe and reliable during operation of this device.

4, this device has characteristics such as simple installation and service expenditure be low.

5, this device is suitable for that electricity is arranged, does not have electricity and do not thinking to have under the electricity consumption situation and can switch neatly and operate.

6, because the self-locking performance of worm reduction box guarantees that ball nut does not reverse, safe and reliable.

In a word, the small-sized elevator of torch that the utility model provides two controls, be the desirable small home dwelling house hand of people from dual-purpose ladder, also be applicable to that the public place is with ladder simultaneously.
