LT5014B - A lift - Google Patents

Abstract

The invention relates to transport, particularly, to lifts. A lift comprises a vertical frame (1) with guides (2) to which mobile by a slider (3) is connected a platform (13) and lift and control systems, a lift system is a screw transmission system, which comprises a screw with a nut, which is disposed in a slider and belt trapezium drive, which comprises an engine, two pulleys, one of which is disposed on a shaft of an engine and second is disposed on a screw, a pulleys are connected by trapezium belts.

Description

The invention relates to the field of transport, specifically to lifts, and can be used from the balcony of the ground floor of an apartment building to lift or lower people with neglect.

There is known a hoist having a vertical stand for moving a carriage by means of a chain drive, having a rotating platform and its tipping mechanism consisting of a clamping element which is mounted on a platform and a support element mounted on a riser, wherein the clamping element is made in a hook shape with a curved the element consists of a bracket with a rear breaker mounted on it and a roller engaging the hook, the concrete bracket being able to move vertically with respect to the rack (see Soviet Union Patent No. 1689273, B 66 B 9/00, A 22 C 17/00, 1991 ).

There is a known elevator consisting of a vertical cranking rack consisting of two C - shaped profiles interconnected and the lifting platforms connected to a slider that is movably mounted inside the rack. The platform moves up and down with the help of rollers and protrudes sideways on both sides of the rack. Hydraulic hoist consisting of a cylinder with a shaft mounted close to the guide vertical stand. The rope system connecting the platform guide rack and the hydraulic hoist has a first unit mounted on the upper side of the rack, a second unit rigidly mounted on the lower side of the hydraulic hoist, a third unit connected to the outer end of the hydraulic hoist shaft and a rope then moves up and through the third block down then around the second up and around the first block down, the other end of the rope being connected to a lifting platform (see U.S. Patent No. 5,351,787, B 66 B 11/04 P> K «Μ3θ6ρβτβΗΜΗ CTpaH Mupa ”, 36-12-95).

The use of a hydraulic lift with a rope system is extremely unreliable and inconvenient, especially when using a lift to lift or lower people with disabilities, requires high maintenance and economic costs.

The object of the invention is to increase convenience and reliability and to reduce economic costs.

The stated purpose is achieved by the lifting and control systems of a hoist consisting of a vertical rack with guide rails with a platform slidably mounted on a slider, wherein the hoist is made by a screw conveyor system 5014 B

In the form of -2mos, consisting of a propeller with a working nut mounted on a slider and a V-belt drive consisting of an engine, two V-belts and two pulleys, one mounted on the motor shaft and the other on a propeller connected by parallel V-belts.

The essence of the invention is explained in the drawings.

The drawing shows: a front view of the a-lift, a side view of the b-lift.

The hoist consists of a stand 1 with guide 2, which is fixed at the bottom by anchor bolts to the concrete base and at the top to the wall. A slide 3 is mounted on the guides 2 with a working nut 4 which engages with a screw 5 of the propulsion system. The working nut 4 is made of caprolone material, which enables smooth movement without additional noise. The slide 3 rests on the guides 2 with the help of pads 6 and wheels 7. Pads 6 are made of caprolone material, which transmits smooth friction without additional noise. The safety nut 8 is mounted on the screw 5 below the slider 3 and moves with the load 5 unloaded until the main nut 4 is worn. When the main nut 4 is worn, all the load falls on the safety nut 8. V-belt drive consisting of two pulleys 9,10 of which is mounted on the shaft of the motor 11 and the other on the propeller 5 connected by two trapezoidal belts 12. The welded platform 13 is bolted to the slider 3. The control panel 14 is attached to the handrail 13 of the platform 13. duplicate. Two of them ensure that the slider 3 stops in the upper position and the other two in the lower position. The limit switch 17 is for signaling the position of the operating nut 4, i.e. y. a red light comes on in the event of a worn thread. The cover 18 of the electrical panel has green and red tell-tale lights.

Kettle works as follows.

When the on / off switch on the control panel 14 is pressed, the green light on the electrical panel 18 lights up. The disabled person rides the wheelchair on the platform 13 in the up position. Pressing the lower control panel button lowers platform 13 with a person. When the lower position is reached, the lift switches off and stops automatically. To move up, press the top button of control panel 14. If desired, platform 13 can be stopped in any position. To do this, press the center button 14 on the control panel. You can then continue moving in any desired direction until plateau 13 stops automatically.

Compared to the prototype, a new set of structural elements,

-3Comfortably, with little economic cost, people with disabilities can move freely from the balcony of their apartment on the ground floor of an apartment without anyone's help.
