Abstract
The utility model provides a coal rock heading machine large-gradient testing stand. The coal rock heading machine large-gradient testing stand is mainly characterized in that a 25-degree foot foundation is made on the basis of a soil ground. Pre-embedded bolts are cast inside the plane on the top of the 25-degree foot foundation through cement concrete. A 25-degree frame is arranged on the pre-embedded bolts and fixed through nut 3 connection. One end of a guardrail is connected with the 25-degree frame while the other end is connected on the plane on the top of the 25-degree foot foundation. Cable embedded parts are cast on the rear wall of the 25-degree foot foundation through cement concrete. A guide rail is arranged below the cable embedded parts. A hoisting speed reducer and a pulley are arranged on the 25-degree foot foundation and connected with a hoisting wire rope. The other end of the hoisting wire rope is connected with a suspension hook. Granite slabs are laid on the surfaces of slopes on the two sides of the 25-degree foot foundation. The coal rock heading machine large-gradient testing stand having a simple structure and a low cost effectively confirms the maximum climbing angle of a coal rock heading machine and meanwhile ensures the safety of test operators and testing equipments. The coal rock heading machine is thus enabled to smoothly dig a tunnel in the underground.
