The invention relates to the technical field of coal mine underground support, in particular to a crawler-type gantry support which comprises a crawler walking unit, a crawler support, a lifting column, a side support unit, a connecting beam, a top frame unit and a stabilizing unit. The mine tunnel supporting device can solve the following problems existing in the process of supporting a mine tunnel in the prior art that movable supporting cannot be carried out, multiple supporting devices need to be used for repeated supporting, cost is wasted, the top wall of the mine tunnel cannot be comprehensively supported, the top wall of the mine tunnel is prone to cracking, and safety accidents occur; the side wall of the mine tunnel cannot be supported, so that the supporting safety cannot be ensured, and the hidden danger of causing safety accidents still exists; the top wall and the side wall of the mine tunnel can be comprehensively supported, so that the working range of workers in the mine tunnel is completely supported, movable supporting can be conducted, cost waste caused by repeated supporting of the mine tunnel is avoided, and fracture of the mine tunnel can be effectively reduced by comprehensively supporting the mine tunnel.

    本发明涉及煤矿井下支护技术领域,特别涉及一种履带式龙门支护,包括履带行走单元、履带支架、升降柱、侧边支护单元、连接梁、顶架单元和稳定单元;本发明能够解决现有技术对矿道进行支护的过程中存在的以下问题:无法进行移动支护,需要使用多个支护装置反复支撑,浪费成本,且无法对矿道顶壁进行全面支护,导致矿道顶壁容易发生破裂而发生安全事故;矿道侧壁无法得到支撑,从而无法确保支护的安全性,仍然存在引发安全事故的隐患;本发明可以对矿道的顶壁和侧壁进行全面支护,从而对矿道内部工人的工作范围完全支护,且可以进行移动支护,避免对矿道反复支撑而浪费成本,且通过对矿道全面支护可以有效减少矿道的破裂。
