Support devices can ensure the stability of the working face and prevent the collapse of coal and rock on the roof and side walls, thereby ensuring the safety of workers. Commonly used support devices mostly adopt a straight beam frame structure. This force-bearing method is relatively direct. When the bearing capacity is large, higher requirements are placed on the structure, material and foundation of the equipment.

[0004] Now, a rapid support device for coal mine excavation is proposed to solve the above problems. Utility Model Content

[0007] The high-strength load-bearing structure includes two groups of first fixing seats, the two groups of first fixing seats are fixedly connected to the front side of the top of the fixing plate, the top of the two groups of first fixing seats are fixedly connected to the first arch frame, the rear side of the top of the fixing plate is fixedly connected to two groups of second fixing seats, the top of the two groups of second fixing seats are fixedly connected to the second arch frame, and the tops of the first arch frame and the second arch frame are fixedly connected to the support plate.

[0008] As a further technical solution of the present invention, two groups of the first fixing seats are symmetrically arranged, and two groups of the second fixing seats are symmetrically arranged.

[0009] As a further technical solution of the present invention, the main unit is electrically connected to the control seat, and the four groups of universal wheels are symmetrically arranged.
