Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and in particular to a power supply device for vertical transportation tools. Background Art

[0002] Vertical transportation tools are tools used to transport goods or people. For example, the common vertical lifts in life belong to vertical transportation tools. With the development of society, the use of elevators has become more and more common. They have transitioned from being used only in commercial buildings and hotels to being used in office buildings, residential buildings and other places. With the popularization of elevators, people's lives have become more convenient, but the number of elevator accidents has also gradually increased, and people have begun to pay more and more attention to the safety protection measures of vertical lifts. When the elevator is in operation, each part requires power support, such as the elevator machine room, car system, door system and various safety protection devices, and the existing elevators all use the power cable with the elevator to supply power, which not only requires the traction force and power consumption of the traction support power cable to be increased, but also the power cable that moves with the car and passes through the elevator shaft is relatively long. Usually, the power cable is in a state of continuous bending during the movement of the car. Therefore, the power cable will cause fatigue damage to the outer rubber due to frequent bending, and then there is a hidden danger of greater electrical failure. Summary of the invention
