At present, the compact high precision lifting device that in the market uses is mostly to guide cylinder elevating mechanism or the lifting of fiber V belt translation Mechanism.Wherein：Cylinder elevating mechanism is guided mainly to move up and down using the aluminum pipe transferring work piece of one layer of one layer of set, between every layer of aluminum pipe There is a dimension precision requirement, and aluminum pipe is not easy long, otherwise easy increase motor operation burden, therefore this elevating mechanism uses Easily it is subject to aluminum pipe weight and load weight etc. to limit；And fiber V belt translation elevating mechanism, depend merely on fiber V belt translation and cannot be guaranteed Transmission accuracy in transmission process, will increase sensor and related supporting limiting device, therefore in the high place of transmission precision prescribed Use, it is not easy to control lifting precision.
Chinese patent CN201720116634.2 discloses a kind of electric belt elevator, which includes reel, electricity Machine, side frame, belt, suspension hook, gearbox, further include forward and backward stable pulley, and the belt is wrapped in reel and two stable pulleys On, strap end is connected with suspension hook, and the motor and gearbox are fixed on side frame.The lifting leather machine belting as driving-chain, To ensure that transmission is smooth, but because belt is easy to shape when being lifted and being loaded, it is unfavorable for keeping lifting transmission accuracy, occurs at the same time Phenomena such as abrasion, burning.
The content of the invention
To solve the above problems, the present invention provides a kind of high precision small electric lifting device, can ensure to rise in load Preferable stationarity and accuracy are kept during drop so that lifting operation is smooth.
Small-sized electric lifting device of the present invention, including rack, Rolling motor, drive and transmission belt, driving wheel tube On Rolling motor, described transmission belt one end is fixedly connected with drive and is wrapped on drive, and the other end connects with load Connection mechanism connects；It is characterized in that：The transmission belt is steel band；The load bindiny mechanism includes connection locating rack, is connecting Its intermediate junction device with steel band one end Dynamic link library can be realized by being set on locating rack.
The present invention using steel band be used as elevator transmission belt, avoid conventional drive belt it is yielding cause elevator lifting calmly The defects of position precision is not high；At the same time by setting achievable Dynamic link library between the two between steel belt and mechanism loading The problem of intermediate junction device, the lifting action irregularity for synchronously overcoming steel band to be brought as transmission belt.
Specifically, the intermediate junction device includes intermediate connector, compression spring and steel band fixing piece；The connection positioning Erection is equipped with T-shaped mounting groove；The intermediate connector is inverted T-shaped, is placed in T-shaped mounting groove, and its upper part stretches out T-shaped mounting groove Notch；The compression spring sleeve is loaded on intermediate connector, and end face and the bottom surface of T-shaped mounting groove upper end notch lean thereon, its The base upper surface of lower face and intermediate connector leans；The steel band fixing piece is fixedly connected with steel band end, and is fastened It is sleeved on the top that intermediate connector stretches out T-shaped mounting groove notch；When steel band is lifted, steel band fixing piece drives intermediate connector Rise, drive connection locating rack to rise overally so as to extrude compression spring, when steel band declines, compression spring opens, and makes connection locating rack whole Body smooth-going declines.
Assembled for the ease of part of appliance, the steel band fixing piece includes preceding steel band briquetting and rear steel band briquetting, in described Between the top of connector one straight slot is set, steel band end is placed in the straight slot, during preceding steel band briquetting and rear steel band briquetting are fastened on Between connector top, two side portions of the steel band end beyond straight slot length are compressed and are fixedly connected.
In order to which steel band pressing fixation is more firm, the preceding steel band briquetting and rear steel band briquetting have oblique pressure matched each other Conjunction face, to increase the frictional force of steel band and briquetting, makes steel band pressing more firm.
The intermediate connector top ends set boss, and the preceding steel band briquetting and rear steel band briquetting are correspondingly arranged groove, Boss and groove clamping, drive intermediate connector to rise when front and rear steel band briquetting is increased by steel strip driving.
In addition, the present invention sets steel band guiding groove below the drive, in rack close to the side of steel band guiding groove Steel band pinch roller is set；The steel band pinch roller is bonded with steel band all the time, and keeps steel band to be lifted along steel band guiding groove, further to protect Demonstrate,prove elevator lifting smooth-going.
The scheme being more highly preferred to is that the steel band pinch roller is installed in rack by supporting rack and installation pedestal, installs base Seat is fixedly mounted in rack, and supporting rack lower part is hinged with installation pedestal, and supporting rack top is connected with the shaft of steel band pinch roller； Tension spring is vertically arranged between the supporting rack top of the steel band pinch roller and installation pedestal.In this way, steel band pinch roller can be in tension spring It is bonded all the time with steel band under active force, the outer rim energy relative motion of the axis and wheeled steel of steel band pinch roller.In steel band lifting process, Steel band itself constantly around axis on the wheeled steel of rotation, can suppress steel band downwards, prevent it from having upward fortune by steel band pinch roller The dynamic trend for departing from guiding groove, ensure that steel band traveling comfort, while can reduce the friction between steel band pinch roller and steel band Power, reduces steel band abrasion.
In order to further improve lifting positioning accuracy, the rack is equipped with positioning column, is corresponded on the connection locating rack Equipped with locating slot.Specifically, when loading hoisting depth close to preset height, during continuing to lift up, positioning column insertion In corresponding locating slot, positioning is realized.
Installed for convenience of mechanism loading, the connection locating rack bottom is fixedly connected with handle connecting piece, and the handle connects Fitting is equipped with the bullport with locating slot perforation；During lifting, steel strip driving load bindiny mechanism moves upwards, positioning column insertion The locating slot on locating rack is connected, and is pierced by by the bullport of handle connecting piece.At this time, the sense on connection locating rack Answer device toggled, send signal and leave the motor off rotation, steel band stops continuing to rise, and realizes the accurate fixed of load lifting Position.
In addition, the present invention can use single transmission wheel structure, as stated in the Background Art, double transmission rolling hitches can also be used Structure, i.e.,：It is symmetrical on the Rolling motor to be set with two drives, symmetrically set in the left and right sides of the connection locating rack Put T-shaped mounting groove, and two sets of intermediate junction devices of corresponding installation.Certainly, corresponding to two drives, corresponding steel band wheel press Structure, positioner etc. are also correspondingly arranged two sets.Relative to single transmission wheel structure, double transmission wheel structures will make the liter of lifting device Drop is more steady.
The present invention realizes the lifting of weight using steel band as transmission belt, ensure that the stationarity and essence of lifting device lifting True property；Meanwhile the present invention ensures that steel band lifting is smooth, realizes high accuracy by steel band and the Dynamic link library of load bindiny mechanism Lifting transmission.
