Abstract
The utility model relates to a coal mine tunneling machine with a safety device. The coal mine tunneling machine comprises a tunneling machine with a cutting head at the front end; a high-strength protective shed made of steel plates is erected at the top of the tunneling machine through at least four sets of hydraulic cylinder groups in hinged joint; each set of hydraulic cylinder group comprises two hydraulic cylinders which are in a herringbone arrangement; and at least two jumbolters are arranged on the protective shed. In the working process of the coal mine tunneling machine, the height of the protective shed and the front and rear shielding positions relative to the body of the coal mine tunneling machine can be adjusted by controlling the expansion and contraction of the piston rods of the hydraulic cylinders; a tunnel roof can be timely supported as required, so that falling rocks are effectively prevented from injuring workers and the coal mine tunneling machine so as to ensure the safety of the workers and the coal mine tunneling machine during the tunneling process.
Description
Technical field
The utility model content belongs to colliery heading equipment technical field, relates to a kind of colliery development machine with safety device.
Background technology
The colliery utilizes development machine to carry out in the course of work of tunnel initating, the rock that falls from top board may injure the workman, also may cause the development machine damage of components, this area is needed a kind of equipment that can guarantee workman and development machine device security in tunneling process badly for this reason.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, and a kind of rational in infrastructure, easy to use, the colliery development machine that can guarantee the band safety device of personnel and development machine device security is provided.
Be used for realizing that the technical solution of foregoing invention purpose is such: the colliery of the band safety device that provides comprises the development machine of a front end band cutterhead with development machine, pass through high-strength steel sheet protection canopy processed of the hinged Zhi Liqi of quadruplet hydraulic cylinder group at least at the development machine top, said every cover hydraulic cylinder group is formed by small one and large one two hydraulic cylinders of arranging by " people " font, is provided with at least two jumbolters at protection canopy.In the development machine course of work, piston rod by the control hydraulic cylinder flexible, can regulate the height of protection canopy and with respect to the position of screening, the front and back of machine body of boring machine, and as required back is carried out immediate support, thereby can prevent effectively that the rock that falls from injuring workman and development machine equipment, guarantee the safety of workman and development machine in the tunneling process.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model, and the protection canopy among the figure is positioned at body upper.
Fig. 2 is the structural representation of this embodiment when protection canopy is positioned at the fuselage front upper place.
The title of each label is respectively among the figure: 1-jumbolter, 2-protection canopy, 3-hydraulic cylinder (greatly), 4-hydraulic cylinder (little), 5-development machine.
The specific embodiment
Below with reference to accompanying drawing the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, the colliery of band safety device described in the utility model is made up of development machine 5, protection canopy 2, jumbolter 1 and hydraulic cylinder etc. with development machine.The fuselage top of development machine 5 is hinged to be provided with quadruplet or to overlap the hydraulic cylinder group more, each hydraulic cylinder group is formed by small one and large one two hydraulic cylinders 3 of arranging by " people " font, 4, top at big hydraulic cylinder 3 is hinged with protection canopy 2, control hydraulic cylinder 3,4 piston rod flexible, can regulate the height of protection canopy and canopy face with respect to the position of machine body of boring machine, prevent that the rock that falls from injuring workman and development machine equipment.Protection canopy 2 is made of high-strength steel sheet, and end face is the plane, can install two or more jumbolters 1 on it.In the tunneling process, control hydraulic cylinder 3,4 flexible, jumbolter 1 can be rested on the suitable position of top board, thereby hole.
