Abstract

The invention relates to the mining industry and m. used in roadheaders selective action during the workings. The goal is to reduce the energy intensity of the downhole treatment process. The executive unit of the roadheader includes a disk 1 with roller cones 2, the shaft of which is connected to the gearbox (P) 3, and an arrow with a drive shaft and a drive head. The boom is made with a fork 7. The drive shaft is connected to the drive head by means of a cardan shaft 4 placed in the crosspiece opening (K) 6. The latter is installed in the fork 7 of the boom so that it can be rotated relative to the boom axis by means of hydraulic jacks (HD) 8. The cases of the central drive 8 are hinged mounted on the boom, and the rods on K 6. At the same time, P 3 is made planetary and is installed to rotate relative to K 6. It is installed P 3 that can be rotated relative to K 6 by means of additional DG 9, whose bodies are hinged to K 6, and 3. On cutting, the cutting disk 1 rotates around its axis coinciding with the axis of the boom. It deviates from the boom axis in a vertical plane at a certain angle together with K 6, shell 5 and P 3 using the main HD 8. In this case, DG 9 keeps the cutting disk 1 from shifting in the horizontal plane. During processing, the intake disc 1 deviates from the axis of the boom in the direction opposite to the direction of the downhole processing, with the aid of heads 8 and 9. 5 sludge.

Description

The invention relates to the mining industry and can be used in roadheaders for selective action during excavations.

The purpose of the invention is to reduce the energy intensity of the downhole production process.

FIG. 1 shows the executive body of the tunneling machine, side view; in fig. 2 - the same, top view; in fig. 3 and 4 kinematic scheme; in fig. 5 is a section A-A in FIG. one.

The executive body includes a cutting disc 1, equipped with roller cones 2, located with a flat surface parallel to or at an angle to the plane of the disk 1. planetary gear 3, propeller shaft 4, gear shell 5, cross 6, fork 7 booms, hydraulic jacks 8 booms, hydraulic jacks 9 crosses, gear coupling 10.

Hydrojacks 8 booms are hinged with housings on the fork 7 booms and rods on the cross 6, which makes it possible to rotate the cross 6 relative to the axis of the slide. Hydrojacks 9 crossings are hinged by the body on the seat

Tin 6, and a rod on the side of the gearbox 5, which makes it possible to rotate the planetary gearbox 3 with the cutting disk 1. Thus, by means of hydraulic jacks of the boom, the planetary gearbox 3 with the cutting disk 1 can deviate from the boom axis in the vertical plane together with the crosspiece 6 gimbal suspension. In addition, the planetary gear 3 with the cutting disk 1 can deviate from the axis of the cross 6 in the horizontal plane With the help of hydraulic jacks 9 of the cross. By combinations of deviations in the vertical and horizontal planes, it is possible to obtain the inclination of the cutting disc to the bottom of the mine at a given angle in any plane.

The torque from the drive shaft of the gearbox is transmitted by means of the gear coupling 10 and the drive shaft to the planetary gearbox 3. The drive shaft allows the planetary gearbox to deviate from the boom axis.

The executive body works as follows.

When nicked, the cutting disk 1 mounted on the output shaft of the planetary gearbox 3 rotates around its axis coinciding with the axis of the boom, deviates from the axis of the boom in a vertical plane at an angle, together with the gimbal crossbar, shell 5 and the planetary gearbox 3, jack jacks 8. At the same time, the jacks of the 9 crosses keep the cutting disk 1 from shifting in the horizontal plane.

Then the cutting disk 1 together with the boom of the combine is fed to the bottom and after the notch it returns to its original position with the help of hydraulic jacks 8. During processing, the cutting disk 1 deviates from the axis of the boom to the side

opposite to the direction of machining of the bottom, at an angle of up to 12 ° with the help of hydraulic jacks of the boom 8 and hydraulic jacks 9 crosses, which is necessary to prevent rubbing of the tool.

The planetary gearbox 3 of the executive body serves to unload the drive shaft 4.

When the planetary gear is displaced from the axis of the boom, the driveshaft moves into the hole of the crosspiece of the gimbal.

The proposed design also allows conducting and selective mining in the mines of any section.
