An embedded safety elevator includes a van body, a motor, a battery, a driving wheel, a transmission rod, an embedded elevating device, and an inwardly concave spiral guide rail. The embedded elevating device is embedded in the guide rail and can move up and down along the guide rail; the embedded elevating device is fixed on the van body to drive the van body to move up and down, the motor and the battery are mounted on the van body and are connected with the driving wheel, the driving wheel is connected with the transmission rod, and the transmission rod is further connected with the embedded elevating device. The motor is started to drive the driving wheel to rotate, the driving wheel drives the transmission rod to rotate, the transmission rod transmits the power to the embedded elevating device for driving the embedded elevating device to spirally elevate.

The vertical support structure includes a half tube and a mounting member. The half tube has an inner surface defining a receiving space and formed with a series of axially spaced-apart helical groove halves. The mounting member is connected to an outer surface of the half tube. A lifting device is also disclosed, and includes a plurality of the vertical support structures, a plurality of rotation units, a plurality of slide housings, a lift carrier, a drive motor and a plurality of transmission units.

The invention relates to a drive unit which comprises a motor (6)-driven spindle (5), rollers (2, 3), and cables (11), and which has a favourable transmission ratio, specifically N:1 in which N=4+n, and n is an integer between −2 and 8 including 0. Said unit is used to move loads and people, is particularly suitable for lifts, is space-saving, environmentally friendly, low-maintenance, economical in terms of energy consumption, and call be used both in the construction of new lifts and in the renovation of older installations. It allows the installation to be operated securely, and people and loads to be transported at high speeds. It can, for example, be installed at the lower or upper end of a shaft, or also outside of the shaft. It can be used for movement in a vertical, horizontal and also inclined direction, and may be provided with a counter weight.

An elevator drive for a rope traction elevator, which is intended for installation in an elevator hoistway, includes of a gear with a traction sheave, a motor in an upright position on top of the gear, a brake and suspension elements which are slung over the traction sheave and provide vertical motion for an elevator car with a counterweight. The motor and the gear are inclined at an angle to the vertical. With this slightly tilted arrangement no part of the motor extends beyond the horizontal boundary of the gear. Furthermore, the brake is a part of the gear and non-detachably fastened to it, which makes it possible to mount the motor on the gear, and to dismount it therefrom, without difficulty.

An elevator drive has an electric motor 12 which drives a worm 30 that drives a gear 20,28 on a shaft 22, at right angles to the worm 30. The output shaft is in the horizontal plane, and an elevator rope sheave 10 is attached to this shaft 22. The shaft 22 is mounted on two bearings 32,36, at opposite ends of a single piece case 14. The drive is assembled by first inserting the gear 20,28 through the side of the case 14, then inserting the shaft 22 through one end of the case through the gear 20,28 and into the bearing 36. Then a thrust plate 40 is tightened down on the end of the shaft 22 to hold the shaft in place on the bearing's inner race and also thrust the gear 20,28 onto the shaft 22. The worm 30 is then inserted through the top of the case 14. Both shaft support bearings 32,36 are machined on the same axis.
摘要:
A compact and simple elevator system is disclosed which does not require a counterweight, a hoistway rope, a winding drum, safety devices such as an emergency stopping device, a speed governor or the like, and in which the installation space as well as the production costs thereof can be reduced, and which is most suitable for installation in private homes. The elevator system comprises a hoistway, an elevator car accommodated in the hoistway and movable in the vertical direction, a screw shaft vertically disposed in the hoistway and having a screw thread formed on the outer peripheral surface thereof, a rotary element mounted on the elevator car and adapted to be threadedly engaged with the screw shaft, a drive source mounted on the elevator car for driving the rotary element to rotate, and a mechanism for restraining the rotation of the screw shaft at least in the normal operating condition of the elevator system, whereby when the rotary element is driven to rotate by means of the drive source, it is caused to displace vertically along the screw shaft to thereby move the elevator car in the vertical direction.
