Abstract

The invention relates to equipment for the mining industry and expands the field of application of the support-turning device due to the constant application of force from the hydraulic cylinders of rotation (PSC). The device enters the base-connected 3 of the PEG 2, which are kinematically connected with the radial grooves 4 of the turntable 5 by means of the rollers 6. The rollers 6 are hinged on the forks 7 located on the rods 8 and 9 of the PEG 1 and 2. The forks 7 are attached carriages 10 interacting with guides I2. When the rods 8 and 9 move in opposite directions, the rollers 6, rolling in the radial grooves 4, transmit the torque to the turntable 5. It rotates around the axis of the subframe 15 at an angle corresponding to the movement of the rods 8, 9. The reaction is perceived by the base 3 through the turntable 5 and the main one and 2, and the guides 12 through the forks 7 and carriages 10. As a result, the rods 8, 9 are protected from bending loads. 4 il. (L with

The invention relates to equipment for the mining industry, and, moreover, to the bearing and turning mechanism of the working bodies of tunneling machines, and can also be used in other branches of the national economy.

The aim of the invention is to expand the field of application of the turntable at the expense of constant. shoulder force on the side of the turn cylinders.

FIG. I shows the supporting-torsional device, general view; FIG. 2 is a view A of FIG. I; in: FIG. 3 -

section bb in fig. I; in fig. 4 is a view of B in FIG. 3

The slewing device consists of hydraulic cylinders 1 and 2 turning associated with the base 3, for example, with the help of Hymouths and kinematically associated with the radial grooves 4 of the turntable. 5 by means of rollers 6 pivotally mounted on forks. 7 rods 8 and 9 turn cylinders. The forks 7 are bolted to the carriage IO and 11, which cooperate with additional guides 12 parallel to the hydraulic cylinders 1 and 2 of the rotation. 30 Additional guides 12 are connected to the base 3 by means of bolted joints, and from the side of the rotary plate I 5 - through the half-circular H-shaped cross-section BB, the bracket 35 is 13, placed with a gap in the circular groove 14 of the rotary platform 5 interacting with vertical

axle axle 15.

The hinge-swiveling device works in a trace; in a manner.

When the rods 8 and 9 of the hydraulic cylinders 1 and 2 are rotated in opposite directions, the rollers 6, rolling in the radial grooves 4, transfer the torque to the turntable 5, which rotates at an angle corresponding to the movement of the rods 8 and 9, around the axis binder 15. The reaction of the bottom is perceived by the base 3 through the turntable 5 and the hydraulic cylinders 1 and 2, and the additional guides 12 through the forks 7 and the carriages IO and II. The guides 12 transfer the downhole reaction to the base 3, and from the turntable 5 side — through the bracket 13. Thus, the slots 8, 9 are protected from bending loads. The circular groove 14 contributes to the rotation of the platform 5 at the required angle.

Formula of invention

A turntable, which includes a base, rotational cylinders connected to the base, the rods of which are equipped with forks at their ends, a turntable with a guide that differs from the fact that, in order to expand the area of application due to the constant shoulder force of rotation cylinders, forks are provided with rollers and carriages attached to them, and the guides on the turntable are made in the form of radical grooves in which the rollers are mounted with the possibility of translational movement, while the bases and it is equipped with additional n-guides rigidly fixed on it, interacting with carriages and installed parallel to the hydraulic cylinders of rotation, rigidly fixed on the base.
