It evolved from coal cutters and is a large and complex system that integrates mechanics, electrical systems, and hydraulics. It operates in harsh environments, and any malfunction can lead to the interruption of the entire coal mining operation, resulting in huge economic losses. The outriggers are used to support the structural components of the bridge frame. Existing coal mining equipment requires the use of outrigger hydraulic cylinders for support and fixation during operation.

[0003] Currently, coal mining equipment often suffers from uneven outriggers during operation, leading to a deviation in the center of gravity and resulting in low installation stability and load balance. Utility Model Content

The No. 1 servo motor 5 operates, driving the two No. 1 lead screws 7 to operate. The two right-side clamping structures 11 limit the right side of the two hydraulic cylinders 1. Then, the No. 2 servo motor 6 is controlled to operate, driving the two No. 2 lead screws 8 to operate. The two left-side clamping structures 12 cooperate with the right-side clamping structures 11 to clamp and fix the two hydraulic cylinders 1, while making the hydraulic cylinders 1 symmetrically supported. Compared with related technologies, the symmetrical support leg hydraulic cylinder for coal mining equipment provided by this utility model has the following beneficial effects: it can prevent the support legs from being unsymmetrical, resulting in a deviation in the center of gravity, which leads to a low installation stability and load balance of the coal mining equipment.
