A mine assembled steel pipe arch shed

Abstract

This utility model relates to the field of mine safety facilities technology and discloses a prefabricated steel pipe arch shed for mining, including a support column, an outer frame, and a sleeve. A top beam is slidably connected to the middle of the support column, and a connecting assembly is installed between the support column and the top beam. The support column is slidably connected to the middle of the outer frame, and multiple insertion holes are evenly spaced in the middle of the support column and the outer frame. A locking assembly is installed between the support column and the outer frame, and the locking assembly includes a pin. The pin is inserted into the middle of the insertion hole, and a locking rod is slidably connected to the middle of the pin. A fixing block is fixedly connected to the middle of the sleeve. In this utility model, after the steel pipe arch shed is erected, the insertion rod is slidably pushed towards the middle of the sleeve and then aligned with the slot and released. When a strong spring pushes the insertion rod back to its original position, the insertion rod can be inserted into the slot, thereby connecting adjacent outer frames into a whole and improving overall stability.
