Description

Underground electric scraper convenient for switching power sources Technical Field The utility model relates to the field of electric scooptrams, in particular to an underground electric scooptram convenient for switching power sources. Background The electric scraper is also called as an electric loader, is engineering machinery taking electric power as a power source, and is widely applied to the fields of underground mines, engineering roadways and the like. The electric scooptram with double power sources is generally provided with a double-power electric drive control device, and the double-power electric drive control device can control the electric scooptram to switch between two power supply modes of cable power supply and storage battery power supply, so that the electric scooptram is more flexible and convenient to use. In the prior art, the cable power supply generally depends on a winding and unwinding structure to realize the mode of power supply along with the movement of the scraper body, but under special conditions, if the cable is damaged or the travel exceeds the length of the cable, a storage battery needs to be started as a standby power source to continue power supply operation so as to ensure the normal operation of the electric scraper. The battery power supply module of the electric scraper consists of a plurality of battery modules, module collectors, connecting wires and other parts, is huge and heavy, is distributed on the left side and the right side of the bottom of the vehicle, can increase the difficulty of disassembling, assembling and replacing batteries and overhauling the power supply structure, is compact in the conventional electric control design of the electric loader, and generally integrates a battery pack and a control device in a container box for fully utilizing the space, and is troublesome in disassembling, assembling and replacing the batteries due to the structure. Disclosure of utility model The utility model aims to solve the problems in the background art and provide an underground electric scraper which is convenient for switching power sources.
