Current collector for trolley conductor, construction hoist and power supply system

Abstract

The invention discloses a current collector for a trolley conductor, a construction hoist and a power supply system. The current collector for the trolley conductor comprises a first current collectorand a second current collector, wherein the first current collector comprises a first mounting bracket used for being mounted on first mobile equipment, a first electric brush and a second electric brush which are used for being in contact with a conductive contact surface of a power transmission guide rail, a first pressing mechanism and a second pressing mechanism; the first mounting bracket isconnected with the first electric brush through the first pressing mechanism and is connected with the second electric brush through the second pressing mechanism; the second current collector comprises a second mounting bracket used for being mounted on second mobile equipment, a tensioning mechanism and a third electric brush used for being in contact with the conductive contact surface of thepower transmission guide rail, and the second mounting bracket is connected with the third electric brush through the tensioning mechanism; and a guide mechanism for guiding the first electric brush or the second electric brush to cross the second current collector is arranged on the second mounting bracket. According to the embodiment of the invention, two mobile devices can be supported to sharethe power transmission guide rail, and the spatial relative position between the two mobile devices can be exchanged.

Description

Technical field [0001] The invention relates to the field of power supply, in particular to a collector, a construction elevator and a power supply system for a sliding contact line. Background technique [0002] In the power supply field, equipment often uses cable power supply. But for mobile devices, since the mobile device needs to constantly change positions, in each different position, the mobile device must be able to get power at any time, otherwise it cannot continue to move. The use of cable for power supply has defects such as easy damage and difficult maintenance, and thus the isolated conductor rail (ICR) has emerged. The trolley line includes a power transmission rail laid in parallel along the running track of the mobile device and a current collector set on the mobile device for taking power from the power transmission rail. The current collector runs synchronously with the mobile device and obtains power from the power transmission rail at any time , Provided t...

Problems solved by technology

[0003] Although the existing trolley line can support the power supply to multiple mobile devices on a single power transmission rail to simplify the field wiring of multiple mobile devices, the relative positional relationship between the various mobile devices often cannot be exchanged

However, in practical applications, due to the different mobile requirements between mobile devices, the running trajectories of each mobile device may be different; in addition, according to their respective mobile requirements, the length of pauses required by mobile devices may be different, which may also lead to different There is a need to change the relative position of space between mobile devices, which leads to the laying of power transmission guide rails, which increases the project cost and increases the cost
