Transport vehicle and driving device used for driving pantograph thereof

Abstract

The invention provides a driving device used for driving a pantograph. The driving device used for driving the pantograph comprises a linear motor which is installed on a bottom board of the pantograph through a first high voltage isolation device; and one end of the linear motor is a connection board which is hinged to an output shaft of the linear motor through a second high voltage isolation device, the other end of the linear motor is provided with a groove matched with an apex angle of a lower arm rod of the pantograph, wherein the apex angle is close to the connection board, the first side wall of the groove is hinged to the lower arm rod, and the height of the second side wall of the groove is not smaller than one half of the thickness of the lower arm rod. The pantograph is controlled through the linear motor, pantograph ascending and pantograph descending work of the pantograph is achieved as long as a power supply is provided, space occupied by a compressor in a pneumatic method is saved, and therefore, occupied space of the driving device is greatly reduced, and available space inside a vehicle is effectively enlarged. The invention further provides a transport vehicle provided with the driving device used for driving the pantograph.

Description

technical field [0001] The invention relates to the technical field of vehicle production, in particular to a transport vehicle and a driving device for driving a pantograph. Background technique [0002] The pantograph is the electrical equipment used by the electric traction vehicle to obtain electric energy from the catenary, and it is installed on the roof of the locomotive or motor vehicle. At present, the driving mode of pantographs used in most subways and urban rail vehicles is pneumatic drive. Pneumatic driving methods are divided into two types: cylinder spring type and air bag type. The working principles of the above two driving methods are described respectively: [0003] Among them, the cylinder spring drive mode: the cylinder spring pantograph uses a cylinder containing a compression bow spring and a set of bow extension springs to control the lifting of the pantograph. During specific work, when there is no compressed gas in the cylinder, the moment generat...

Problems solved by technology

However, since the compressor has a large volume and needs to be installed inside the vehicle, it takes up a lot of space in the vehicle and reduces the available space in the vehicle.
