AI Technical Summary

Technical Problem

The existing temporary support methods for underground tunneling equipment in coal mines have problems such as small roof and side protection area, weak adaptability, cumbersome operation, and low tunneling efficiency and safety.

Method used

The tracked full-section temporary support device includes a walking track, a top beam, a top beam telescopic support column, a moving hydraulic cylinder, a forward extension beam, and a forward extension beam telescopic support column. It achieves autonomous walking, large roof and side protection area, and wide range of height adjustment through multi-stage telescopic guide sleeves and lifting hydraulic cylinders, adapting to trapezoidal roadways and terrain with varying slopes.

Benefits of technology

It achieves large-scale roof and side protection, improves support reliability and safety, reduces equipment cross-interference, improves tunneling efficiency and safety, and adapts to complex terrain.

Abstract

This invention discloses a tracked full-section temporary support device, comprising a traveling track and a top beam; both ends of the top beam are hinged to the top ends of the top beam telescopic supports, and the bottom ends of the top beam telescopic supports are hinged to the frame of the corresponding traveling track; one end of a moving cylinder is hinged to the transverse main beam of the top beam, and the other end of the moving cylinder is hinged to the front extension beam main beam of the front extension beam; both ends of the front extension beam are hinged to the top ends of the front extension beam telescopic supports, and the bottom ends of the front extension beam telescopic supports are hinged to the support base. Advantages: The top beam and front extension beam expand the roof protection area through the staggered arrangement of longitudinal auxiliary beams, front auxiliary beams, and rear auxiliary beams; after the side protection plates and front auxiliary beams are opened, full coverage protection of both sides and the face of the working face is achieved, solving the problems of traditional equipment's immobility, incomplete roof and side protection, and small protection area.
