Manual-automatic integral lifting gear

Abstract

The invention provides a lifter which integrates the manual operation and the automatic operation into a whole, and belongs to a small type lift. The invention includes a casing wall, which is directly used as a lift well and an insulative curtain wall; a table, which is used for man to stand on, is fixed on a ball nut, and is lifted up and down in the casing wall; a screw mandrel electric actuating mechanism, which includes a ball screw mandrel that is relatively quiescent, the ball nut which is matched with the ball screw mandrel, the bracket of a driving subassembly, a electric motor whichdrives a worm reduction box to rotate by a shaft joint, an upper supporting structure as well as a lower supporting structure of the screw mandrel, an adjusting screw nut, a driving gear and a drivengear; a manual control subassembly, which includes a handwheel / hand lever, a driving belt wheel, a driven belt wheel, a shaft block, the worm reduction box, a mounting deck of the handwheel, and a spline arranged between the driving belt wheel and the handwheel / hand lever. The invention has the advantages that the design is scientific and reasonable, and the structure is novel; the ball nut cannotreverse because a self-locking device is arranged on the lifter, the invention is light and flexible when being operated by hand, and the switching and the operation are easy. The invention is an ideal lifter which integrates two control methods of the the manual operation and the automatic operation into a whole.

Description

Technical field [0001] The invention relates to a manual-automatic integrated lifting device, which is a ball screw type household elevator, which can be controlled in two manual and / or electric control modes, and is particularly suitable for use in family residences and public places, belonging to the class of small elevators. Background technique [0002] With the aging of society and the improvement of social civilization, people's demand for small elevators is also increasing. Generally, elevators are of traction structure. Such elevators require at least a mini machine room and a simple control room / cabinet. Most of them are suitable for passengers in buildings, but not suitable for low-rise buildings / villas and public places. There are also some small elevators that use ordinary screw rods and winches, which have high energy consumption, high noise and low transmission efficiency during operation. Although the existing elevator has a self-rescue function, it is only for th...

Problems solved by technology

[0004] The Chinese patent applied by the applicant's subsidiary company, patent number: 200620103088.0, "Screw Type Household Elevator", overcomes the above-mentioned shortcomings of the prior art. Driven by a motor, the motor drives the nut through the belt to lift an L-shaped lifting platform to move up and down. The elevator is also equipped with an emergency relief device, which is energy-saving, novel in structure, and beautiful in appearance. It does not need a special building well. Beautiful and elegant, the whole ladder is compact in structure, can make full use of the indoor area, easy to install and low in maintenance costs; but the disadvantage of this patent is that it does not have the structure of manual control function and integrated flashlight
