    Abstract: The present invention discloses electromechanical equipment integrating functions of anchor protection and supporting, including a suspension support system, a power system, an advanced support system, a subsidiary transport system and an anchoring robot system. The suspension support system is fixed on a top end of a coal mining tunnel through an anchor rod to provide support for the system. The power system is mounted at a tail end of a system main beam in the suspension support system. The advanced support system is mounted at a front end of the system main beam in the suspension support system. The subsidiary transport system is mounted on the system main beam in the suspension support system at a rear side of the advanced support system. The anchoring robot system is mounted on the system main beam in the suspension support system between the power system and the subsidiary transport system. Furthermore, the present invention has good turning and slope changing performance, and the transport efficiency of the equipment is high. In addition, an anchoring robot working platform has a buffering function, the anchoring is stable, and the operation efficiency is high.

    Abstract: The sealed coring device for an underground coalbed comprises a rib drill pipe assembly, a tail bearing pack, a motor cylinder assembly and a sampling cylinder assembly. The rib drill pipe assembly consists of a rib drill pipe, a tail drill pipe joint and a head drill pipe joint. The tail bearing pack is mounted in the tail drill pipe joint and configured for protecting an internal structure from relatively rotating during drilling of the rib drill pipe, so that the stability of the sampling cylinder is ensured. The motor cylinder assembly is mounted in the rib drill pipe and configured for providing power for action of a center shaft in the sampling cylinder assembly.
