Hydraulic telescopic protective cover for cutting head of roadheader and implementation method thereof

Abstract

The invention discloses a hydraulic telescopic protective cover for a cutting head of a roadheader and an implementation method thereof. The hydraulic telescopic protective cover comprises a fixed frame, outer square sleeves mounted on the left and right sides of the top of the fixed frame, inner square sleeves slidably connected to inner cavities of the outer square sleeves, and a protective cover body fixed on the tops of the inner square sleeves through supporting rods, the outer square sleeves and the inner square sleeves form a double-arm two-stage square sleeve type telescopic structure, an oil cylinder is arranged in an inner cavity of each outer square sleeve, a piston rod and a cylinder body of each oil cylinder are connected with the corresponding inner square sleeve and the corresponding outer square sleeve respectively, a winding mechanism is arranged on the opposite sides of the two inner square sleeves and rotationally connected with the center of the protective cover body, and the moving end of the winding mechanism is fixedly connected with the side wall of the protective cover body. The hydraulic telescopic protective cover is reasonable in design structure, after the cutting head of the roadheader falls to the ground through a hydraulic system of the roadheader, the protective cover automatically extends forwards to cover and protect the cutting head. The construction safety is guaranteed, the labor intensity of workers is reduced, and the tunneling efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of smilting machine interception head stopped landing protection device, and is specifically a liquid retractable shroud. Background technique [0002] The abbreviation of integrated mechanical evaporation is a comprehensive mechanized equipment integrating a collection of tunnen, container, coal and even support, and a variety of nailed roads. Under the coal mine, the most common is also the most advanced tunneling machinery, in modern coal mine Digging into mechanical production, it has played a very important role. At present, most of the coal mine rejuvenation has used the exploitation machine construction. After the cover is stopped, the cutting head has dropped, and it is necessary to set up a special cut-cut head protection cover to prevent the cut head. The accident occurred; the traditional protective cover is separated from the shroud, the weight is large, and the labor intensity is maintained, ...

Problems solved by technology

[0002] The abbreviation of comprehensive mechanized roadheader is a comprehensive mechanized equipment that integrates multiple functions of tunneling, rock loading, coal transportation, even support, and nailing. It is the most common and most advanced tunneling machine in coal mines. It plays a very important role in the mechanized production of excavation. At present, most coal mine excavation roadways are constructed by comprehensive excavation machines. After the comprehensive excavation machine stops, the cutting head falls to the ground. Personnel accidents occur; the traditional protective cover is a separate protective cover, which has a large weight and volume, requires frequent transfer and assembly, consumes labor, increases the labor intensity of employees, and takes up regular cycle time
