Description

SIDE POWERING-BASED DUAL-SOURCE TRACKLESS ELECTRIC MINING TRUCK CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to the Chinese Patent Application 202110998793.0 filed on August 28, 2021 and entitled "DUAL SOURCE

TRACKLESS ELECTRIC MINING TRUCK BASED ON SIDE POWER

RECEIVING", the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

[0002] The present invention relates to the technical field of dual source trackless

trolleybuses, and in particular to a dual source trackless electric mining truck based on

side power receiving.

BACKGROUND

[0003] A dual source trackless trolleybus uses a wire network as a power source, and is provided with a power battery pack. In a section with a power grid, the trolleybus

is connected with the wire network by means of a trolley pole to drive, charge and store

electric energy. In a section with a wireless network, the trolleybus may use a battery to

drive off the wire network. However, a difference between a dual source trackless

electric mining truck and the dual source trackless trolleybus is that an entrance for

people to get on the dual source trackless trolleybus is at its side, so the trolley pole

may be placed at the top of the dual source trackless trolleybus. However, the dual

source trackless electric mining truck needs to dump and receive minerals, the top is

usually a feeding opening, so it is impossible to place its trolley pole at the top thereof

like the ordinary dual source trackless trolleybus. Moreover, due to complexity of

personnel and vehicles in a mining area, and complexity of ground in the mining area,

it is not as flat as an urban road surface, the dual source trackless electric mining truck

will produce severe vibration when driving, resulting in collision between a power grid

and the trolley pole, so as to suddenly increase current to cause circuit breakdown, and even seriously break a cable of the power grid, threatening life and health of personnel in the area. In view of the above technical defects, a solution is now proposed.

popup assembly, a spring lock assembly, an information acquisition module, a data

calculation module, a data analysis module, and an open circuit execution module, on

the basis of automatic power receiving and disengagement of a side of a dual source

trackless electric mining truck, it further achieves data acquisition, calculation and

comparison of the dual source trackless electric mining truck when it is driving on a

rugged section, and generates a power grid protection open circuit signal, such that the

dual source trackless electric mining truck is immediately disengaged from a power

grid cable, thereby protecting safety of the power grid cable and life safety of personnel

in the area, and when it is disengaged from a non-power grid section, it can

automatically return, taking up less space, so as to ensure that a device will not be

damaged by traffic vehicles, thereby solving a problem that a traditional dual source

trackless trolleybus is not applicable to a mining area.
