Embodiment

[0024] Please refer to Figure 1-4 As shown, an elevator car system, please refer to figure 1 As shown, it includes a low-voltage DC power supply system for the car and the elevator track. There are elevator metal guide rails and traction wire ropes on both sides of the car. The elevator metal guide rails and traction wire ropes form a power supply circuit; the elevator track low-voltage DC power supply system The system includes a power conversion device, a power take-off device and a power communication separator. The mains power is converted into direct current by the power conversion device. Power supply for all electrical equipment.

[0025] Specifically, the power extraction device adopts an electric comb power extraction device, and the power conversion device can specifically convert AC power into DC power through a rectifier, and then reduce the DC voltage to a required voltage, such as a voltage similar to a mobile phone charging device. Converter.

Abstract

The invention discloses an elevator car system. The elevator car system comprises an elevator car and an elevator rail low-voltage direct-current power supply system; the two sides of the elevator carare provided with elevator metal guide rails and traction steel wire ropes, and the elevator metal guide rails and the traction steel wire ropes form a power supply loop; the elevator rail low-voltage direct-current power supply system comprises a power source conversion device, a power obtaining device and a power source communication separator; and mains supply is converted into a direct current through the power source conversion device, and after the direct current passes through the elevator metal guide rails, the direct current supplies power to electric appliances in the elevator car through the power source communication separator and the power obtaining device in sequence. According to the elevator car system, existing metal components such as the elevator metal guide rails, thetraction steel wire ropes and the like in an elevator shaftway are sufficiently utilized, a low-voltage direct-current signal is transmitted through the elevator metal guide rails, power supply is conducted through the power obtaining device, and the elevator car power supply problem is solved by adopting the ultralow-voltage direct-current power supply technology.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car system. Background technique [0002] At present, the traditional elevator car adopts rail positioning, wire rope traction, power supply and communication with the cable, and the AC power on the car top is converted into DC power for internal electrical use through a power converter. The car top contains multiple electrical boxes, which leads to installation and debugging of the power supply system. Complexity, many consumables, many product types and many maintenance items. Contents of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide an elevator car system, which solves the problems of complex installation and debugging, many consumables, many product types and many maintenance items of the power supply system of the elevator car in the prior art. [0004] The present invention adopts technica...
