Embodiment Construction
[0024] A dual-power screw type elevator is composed of elevator system III, power transfer system II, and turbine power system I. It is characterized in that: turbine power system I is installed on the top and side bottom of elevator system III, and the power transfer system System II connects elevator system III and turbine power system I;
[0025] The elevator system III is composed of a landing door 6, a sealed shaft 1, a transmission screw 3, a guide rail, a bracket, a car system 2, a motor gearbox power system and a control cabinet, and the power transfer II System is made up of power transmission shaft 9, spur gear 8 and crossed shaft spur gear 7, and described turbine power system 1 is made up of volute 11, turbine 10 and gas duct 12;
[0026] Described staggered shaft cylindrical gear 7 is installed on the transmission screw rod 3 of elevator system 1, is arranged on the bottom of transmission screw rod 3, and the tooth of gear faces below; Spur gear 8 is connected wit...

The invention belongs to the field of industrial machines and relates to a dual-power screw-type elevator, in particular to a screw-type elevator device with the atmospheric pressure difference being used as the auxiliary power. The dual-power screw-type elevator is composed of an elevator system, a power adaption system and a turbine power system. The elevator system is composed of landing doors, an airtight shaft, a transmission screw, guide rails, a bracket, an elevator car system, a motor gear case power system and a control cabinet. The power adaption system is composed of a transmission shaft, a straight spur gear and a staggered shaft cylindrical gear. The turbine power system is composed of a turbine housing, a turbine and an air guide tube. The dual-power screw-type elevator has the beneficial effect that the screw provides power to make the turbine rotate at a high speed, and the difference between the atmospheric pressure at the upper side of an elevator car and the atmospheric pressure at the lower side of the elevator car is generated in the airtight shaft, so that the auxiliary power for operation of the elevator car is generated. The dual-power screw-type elevator further has the beneficial effect that the electric power can be saved under the condition that the elevator operating speed is increased and the elevator operating stability is improved.
Description
technical field [0001] The invention relates to a dual-power screw type elevator, in particular to a dual-power screw type elevator using air pressure difference as auxiliary power and motor power, and belongs to the field of industrial machinery. Background technique [0002] Since the elevator was born in 1854, it has been used more and more in daily life. As an efficient and convenient power tool, with the continuous improvement of elevator technology, in the 1970s, the appearance of the screw elevator has been used until now. . Screw-type elevators are widely favored due to their wide application and safety advantages; however, since the power drive of screw-type elevators all depends on the electric motor, there are high requirements for the torque and fast and continuous running performance of the electric motor. Larger power. The addition of auxiliary power can greatly reduce the requirements on the performance of the motor without reducing the safety and stability,...
