Description

Technical Field

[0001] This utility model relates to the technical field of underground transportation auxiliary devices, specifically to a connecting component for supporting hydraulic cylinders on a self-propelled underground equipment train. Background Technology

[0002] Mining equipment trains are used to house critical equipment such as motors and reducers for coal mining machines and scraper conveyors. These pieces of equipment are typically large and heavy. Moving these trains allows for convenient transport from one roadway to another. However, these equipment trains are mostly moved by winches and steel cables, which requires laying tracks at the bottom of the roadway and places high demands on the tracks. Furthermore, a broken steel cable can cause the train to lose control, posing a safety hazard. Therefore, the applicant has designed a self-propelled equipment train transmission system. To address this, it is necessary to design a connector that can be installed on the engine and carriages to mount the hydraulic cylinders, thereby meeting current usage requirements.
