Vertical lifting device capable of climbing by manpower and control method thereof

Abstract

The invention relates to a vertical lifting device capable of climbing by manpower, and the device comprises a vertical well, at least a lift car and power systems corresponding to the lift cars in a one-to-one manner. The vertical lifting device capable of climbing by manpower realizes free sliding of the lift cars in the vertical well through arranging supporting disks and a spiral rising rail, and the lift car is clamped with an internal rolling rail of the spiral rising rail through a U-type nave boss, so as to ensure the supporting disks and the lift cars not to fall off the spiral rising rail. The device can realize manual lifting and automatic lifting. Through arranging a plurality of lift cars in the vertical well, one vertical well provides combination of a plurality of lift cars and power structures is realized, and the device operates safely. The device has green environmentally friendly effect of saving land, and even though the device is used in a LOFT house type house in a city, the device has effects of saving space and energy, and is low carbon. The device can be applied in wide rural self-built houses, and has benefits of saving land and providing convenience for the old or people who cannot climb stairs conveniently to live upstairs.

Description

technical field [0001] The invention belongs to the field of transportation equipment, in particular to a manual climbing type vertical lifting device and a control method thereof. Background technique [0002] Human beings have a long history of using lifting tools to transport goods and people. The basic principle of the most primitive lifting system has not changed: that is, when a counterweight is lowered, the load platform is raised. Early lifting tools were basically powered by human power. In 1203, a donkey-powered crane was installed in a monastery on the coast of France, which ended the history of transporting heavy objects by human power. After the British scientist Watt invented the steam engine, the crane device began to use steam as power. Immediately thereafter, William Thomson developed a hydraulically driven elevator, and the hydraulic medium was water. In December 1889, the Otis Elevator Company of the United States manufactured a veritable elevator. It ...

AI Technical Summary

Problems solved by technology

2. The hydraulic elevator uses a hydraulic pump as the power source to push the hydraulic cylinder to expand and contract to realize the lifting function, which has a certain loss

3. The screw elevator uses the screw elevator as the power, which has relatively large loss and is easy to wear

[0007]The working efficiency of the three power structures of the existing vertical lifting device for carrying people and goods: 1. The traction elevator has no intermediate link loss, low loss and high speed

2. The intermediate link of the hydraulic elevator adopts the oil cylinder transmission, which has a certain loss, and the speed is slower than that of the traction elevator.

3. For screw elevators, due to the relatively large relative motion loss of the screw and the nut, the speed increase is hindered, and the lifting is relatively slow.

[0008]The noise of the three power structures of the existing vertical lifting device for carrying people and goods: 1. The noise of the traction elevator adopts the synchronous traction machine is relatively small

2. Since the hydraulic elevator is lifted by pressure, the load noise of the motor is increased and the noise is relatively large.

2. Although the technology of hydraulic pump and hydraulic cylinder used in hydraulic elevators is relatively mature, there are still hidden dangers of hydraulic oil leakage, and the electrical data is relatively complicated, especially the later failure rate is slightly higher

However, the disadvantage of the screw elevator is: the load-bearing is small, and it cannot be used on higher floors. It is not only slow to use on higher floors, but also the screw is too long to support it.

However, the main disadvantages of the inclined elevator are: it occupies a large area, it is not a vertical ascending mode, and its power structure also adopts three known methods: traction elevator, hydraulic elevator, screw elevator
