Description
Technical field
The present invention relates to a kind of manual-automatic integral lifting gear, is a kind of ball wire rod-type home lift, and it can manual and/or electronic two kinds of modes, is particularly suitable for home dwelling and public place and uses, and belongs to small-sized elevator 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 subsidiary/member companies's application of the applicant, 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 the weak point of this patent is: the structure that does not have manual controllable function and torch integral type.
By retrieval, other has the patent of two pieces of relevant electric and hand two control home lift aspects, but different with the application.
Summary of the invention
The objective of the invention is to fill up the prior art blank, a kind of later-model manual-automatic integral lifting gear is provided, mainly be to the technological improvement of the weak point of above-mentioned screw home lift and replenish, thereby a kind of novel unique, small-sized elevator with manual and electronic dual occupation mode and integral structure is provided.The present invention adopts the higher ball screw auxiliary driving of driving efficiency, special guide rail, new fixed sturcture, make complete machine have novel structure, exquisite appearance, also hoistway specially can extensively be applied to electricity or not have switch neatly under electricity and the non-electric situation and operate neatly.
Concrete technology contents of the present invention is: a kind of manual-automatic integral lifting gear is characterized in that: comprise
One leg, described leg are directly made elevator hoistways and sound insulation curtain wall,
One manned, described manned is fixed on the ball nut, lifting in leg,
One screw mandrel formula electric transmission, described screw mandrel electric transmission comprises: a static relatively ball screw and ball nut with matching, be commonly referred to as the rolling lead screw auxiliary driving, and the support of transmission component, with drive worm reduction box by motor by coupler and rotate, 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, and the spline of 1 on driving pulley 4 and handwheel/handle;
Wherein: described setting nut is adjusted predetermincd tension to guarantee the setting accuracy of ball screw;
Described handwheel/handle is installed on the handwheel erecting frame, can be fixed or movable formula and install.
The present invention is when the needs electric operation, handwheel/handle is turned right and is pushed away/draws/produce, spline fitted between driving pulley and handwheel/handle is inoperative, that is to say that handwheel/handle and driving pulley are disengaged condition, handwheel does not rotate when guaranteeing that elevator normally moves up and down, and motor 14 drives ball nuts 12 and drives manned 3 lifting that realizes manned 3 along ball screw 11 up and down then;
And when needs are manually controlled, push away/draw/produce 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 present invention 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 the drive worm reduction box, and designs the self-locking device that worm reduction box is arranged, and ball nut can not reversed.
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 under the electricity consumption situation, have and guaranteed light, flexible when manual, easily switch and operation and safe and reliable.
In a word, manual-automatic integral companion ladder provided by the invention, be the desirable hand of people from two control integrated companion ladders, be applicable to the small-sized elevator that family and public place are used.
