Current collectors for trolley lines, construction elevators and power supply systems

Abstract

The invention discloses a current collector for a trolley line, a construction elevator and a power supply system. Wherein, the current collector for trolley line includes: a first current collector, including: a first brush for mounting on a first mounting bracket on the first mobile device, and a first brush and a second brush for contacting the conductive contact surface of the power transmission rail. Brushes, first pressing mechanism and second pressing mechanism; the first mounting bracket is connected to the first brush through the first pressing mechanism, and connected to the second brush through the second pressing mechanism; the second current collector includes : the second installation bracket for installation on the second mobile device, the tension mechanism and the third brush for contacting the conductive contact surface of the power transmission guide rail, the second installation bracket is connected to the third brush through the tension mechanism; Wherein, a guiding mechanism for guiding the first electric brush or the second electric brush to pass over the second current collector is arranged on the second mounting bracket. The embodiment of the present invention can support two mobile devices to share the power transmission rail, and the spatial relative positions 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 for a trolley line, a construction elevator and a power supply system. Background technique [0002] In the field of power supply, equipment is often powered by cables. But for the mobile device, since the mobile device needs to constantly change positions, in each different position, the mobile device must be able to obtain power at any time, otherwise it cannot continue to move. The use of cable power supply has defects such as easy damage and difficult maintenance, so the isolated conductor rail (ICR for short) came into being. The trolley line includes a power transmission guide rail laid in parallel along the running track of the mobile device and a collector installed on the mobile device for taking power from the power transmission guide rail. The collector operates synchronously with the mobile device and obtains power from the power transmission guide rail at any...

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
