Abstract: The invention discloses a steering mechanism and an independent suspension system. The steering mechanism comprises a steering rocker arm unit, a mid-position locking cylinder, a first power steering cylinder, a second power steering cylinder, a first steering linkage and a second steering linkage; one end of the mid-position locking cylinder is connected with the steering rocker arm unit, and the other end is hinged to a frame; one ends of the first power steering cylinder and the second power steering cylinder are connected with the steering rocker arm unit, and the other ends are hinged to the frame; and one ends of the first steering linkage and the second steering linkage are connected with the steering rocker arm unit, the other ends are connected with knuckle arms, and the knuckle arm is fixed on a wheel rim.

Abstract: A hoist for transferred materials in an underground auxiliary transportation system and a method thereof. The hoist includes a hoist body, guiding plates mounted at two ends of the hoist body through bolts, twist locks mounted at four ends of the hoist body, a driving unit configured to drive twist locks to rotate, transmission assemblies configured to connect the twist locks with the driving unit, ejector pins configured to prevent the twist locks from rotating mistakenly, and a sensor configured to control the hoist to operate and provide protection safety.

Abstract: The present disclosure provides a hoist for transferred materials in an underground auxiliary transportation system and a method thereof. The hoist includes a hoist body, guiding plates mounted at two ends of the hoist body through bolts, twist locks mounted at four ends of the hoist body, a driving unit configured to drive twist locks to rotate, transmission assemblies configured to connect the twist locks with the driving unit, ejector pins configured to prevent the twist locks from rotating mistakenly, and a sensor configured to control the hoist to operate and provide protection safety. The hoist provided by the present disclosure can satisfy the ground-to-air and ground-to-ground transferring requirements for underground materials, and the safety protection sensors can prevent a misoperation of the hoist, can adapt to standard containers of different sizes, has a certain adaptability to narrow terrains, and can improve the stability of the overall mechanism in cooperation with the rope-pulling mechanism.
