Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, in particular to a four-link self-supporting fixed hydraulic bracket type double-speed multi-purpose winch. Background Art

[0002] Winches are primarily used in underground coal mines and other mines for recovering pillars, dispatching, and pulling heavy objects at working faces and tunnels with inclinations less than 30°. Traditional winches are integral longitudinal frame structures with no inherent support devices, requiring ground anchoring or modification for use with single pillars. Due to constraints in on-site working conditions, fully mechanized mining faces typically utilize a four-pressure, two-strut fixed support method for winch support. This cumbersome installation process and the need to frequently relocate the winch during construction severely restrict mining efficiency. Existing winches are unable to freely adjust their speed to high or low according to the actual load, making them incapable of handling widely varying lifting and pulling tasks, reducing their applicability.
