Abstract: The present disclosure discloses a time service and positioning network system for an underground chain-shaped large space in a coal mine. The system adopts a base station-level network internal time synchronization method which takes an optical fiber time service as a main part and takes a satellite time service as an auxiliary part to construct a time service and positioning network system with an unified time within the ad-hoc network base stations, based on the ad-hoc network base stations linearly arranged in the underground chain-shaped large space in the coal mine. Through the network construction, the network stabilization and the network application, the system unifies the time reference of the base station-level network and improves the positioning accuracy of the network application by utilization of the base station-level network internal time synchronization method.

Abstract: An elevation device includes a mounting frame, a rotary actuator fixed to the mounting frame, a shaft connected to the rotary actuator and rotatable with respect to the mounting frame, a drive bar slidably connected to the mounting frame, and a connecting member fixed to the shaft. The shaft defines a helical groove in a lateral surface thereof. The drive bar includes a post that is movably fit in the helical groove. The mounting frame, the shaft and the drive bar constitute a conversion mechanism that converts rotation of the shaft into linear motion of the drive bar. The drive bar is slidable with respect to the mounting frame along a direction that is parallel to an axis of rotation of the shaft.
