Automatic charging pile for mining walking trolley

Abstract

The invention relates to the technical field of mining production, in particular to an automatic charging pile for a mining walking trolley. The automatic charging pile comprises an electric push rod installed on the upper portion of the walking trolley, a contact male head and a plurality of contact female heads installed below a walking track. The walking trolley is hung below the walking track, and the electric push rod drives the contact male head to be close to or away from the contact female head. The plurality of contact female heads are uniformly arranged below the guide rail, the contact female heads are connected with a power supply, and the contact male head is connected with a battery pack in the walking trolley. According to the automatic charging pile for the mining walking trolley, a stable, safe and rapid automatic charging structure is provided, the contact male head is close to or away from the contact female head through the mechanical electric push rod, and therefore contact and separation of the contact male head and the contact female head are achieved; therefore, under the condition that the long-distance walking trolley is powered by the lithium battery, charging is rapid, the structure is simple and stable, and installation is easy.

Description

technical field [0001] The invention relates to the field of mining production technology, in particular to an automatic charging pile for a mining trolley. Background technique [0002] With the development of intelligent walking trolleys in the coal industry, walking trolleys with various drive structures emerge in endlessly, and the biggest difference lies in the research on the energy supply mode of the walking trolleys. For example, if the long-distance battery life is more than 3Km, the self-weight of the walking trolley must not exceed the pressure range of the driving structure. Within the guaranteed pressure range, the cruising range should be guaranteed as much as possible. Therefore, it is particularly important to optimize the charging structure. [0003] At present, the intelligent walking trolleys in the coal industry are mostly powered by lithium batteries. The specific method is to install lithium batteries inside the walking trolley body. However, when it i...
