Abstract

The invention belongs to the technical field of underground exploiting devices for a coal mine and relates to an extensible swinging device for crushing, impacting and tunneling for the underground coal mine. The device mainly solves the problem that a traditional tunneling method using cannon is small in roadway construction section, non-mechanical in operation, slow in construction, low in operation efficiency and safety coefficient and poor in operation environment. Two sets of extensible arms are arranged on a fixed base, each set of extensible arms is composed of two crushing hammers, an inner sleeve, a press block, a cover plate, an adjusting cushion block, an outer sleeve, a rotary base, a rotary bearing, a rotary oil cylinder, an extensible oil cylinder and a lifting oil cylinder. The two crushing hammers are arranged in the inner sleeve, the extensible oil cylinders are connected with the outer sleeve and the inner sleeve, the rotary base is connected with the rear end of the outer sleeve, the lifting oil cylinder is connected with the rotary base and the outer sleeve, and the rotary oil cylinder is connected with the rotary base and the fixed base. The device has the advantages of being high in construction efficiency and safety coefficient.

Description

technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, and in particular relates to a telescoping and swinging device for crushing impact excavation in underground coal mines. Background technique [0002] In the field of coal mine development equipment technology, the main method of traditional rock tunneling in various mines is blasting. The gun excavation is drilled, charged, and blasted with an air-leg pneumatic drill. The gangue that falls from the blast is first manually crushed and then transported out of the working face by a rock rake machine; protect. There are following problems in this blasting rock roadway excavation construction method: 1, roadway excavation section is little: excavation section is generally in 15m 2 Left and right; 2. Non-mechanized operations: blast hole construction and gangue crushing are all manual operations, and the labor intensity of workers is high; 3. Slow construction...
