Tunneling machine support net device

Abstract

The invention relates to a heading machine mesh supporting device which comprises a supporting plate, a support rack, a bottom plate, an overturning oil cylinder, an adjusting axis pin, an overturning axis pin and an adjusting oil cylinder. The front end of the bottom plate is connected with the lower end of the support rack, the rear end of the bottom plate is connected with one end of the overturning oil cylinder, the other end of the overturning oil cylinder is connected with the middle end of the support rack, the upper end of the support rack is connected with the front end of the supporting plate, the rear end of the supporting plate is connected with one end of the adjusting oil cylinder, and the other end of the supporting plate is connected with the support rack. The heading machine mesh supporting device is simple in structure, and reasonable in design, achieves the organic combination and combined operation of a cutting part of a heading machine and the supporting mesh device, is coordinated in motion, is interference-free, greatly reduces labor intensity of workers, improves working efficiency, quickens construction progress, lays a foundation for quick driving, completely prevents the unsafe hazards when underground workers support meshes manually, and achieves whole mechanized operation of downhole mesh supporting.

Description

technical field [0001] The invention relates to a support net device for a roadheader. Background technique [0002] The driving speed of the roadway under the coal mine mainly depends on the support net and bolting time after the roadheader works. At present, most of my country's mine undercarriage nets are manually completed by miners standing in front of the roadheader without any protection. The effective working space in front of the unsupported roadheader is small, the construction process is continuous, and the labor intensity is high. Greatly limits the construction speed, but also has unsafe hidden dangers. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming, provide a kind of supporting net device of roadheading machine, it mainly solves the problem that most of the supporting nets under the mine in my country are manually completed by the miners standing in front of the roadheading machine withou...
