Abstract

1. Mechanized mining support with hydraulic supports on the floor, a sliding system and a canopy placed on them, characterized in that the floor consists of a front floor (1) and a rear floor (2), connected by flexible elements (8) and placed on the floor at least one pair of hydraulic supports (4) is fitted with a device (5) for positioning the supports (4) flexibly connected to the floor runner, while the sliding system of the housing including the hydraulic cylinder (13) is connected to the front floor runner (1).

Description

The subject of the invention is a mechanized mining support intended for supporting the steep slope of these mills. The casing is adapted to lowlanders with high support due to the mid-thigh and thighs of the thigh.

Chest-shaped casings are known, built on two separate runners connected rigidly to each other.

It is advantageous to make the elastic element in the form of a shaped spring which is articulated to the floor rugs. It is also advantageous to provide the rear floor runner with a cover which forms, with a beam pivoted to the canopy, a casing section. A further advantage is the attachment to the floor floors of brackets containing pins securing the prop positioning device.

The use of the casing according to the invention allows for a comfortable space for miners. Moreover, the division of the floor into two articulated parts facilitates the positioning of the casing on an uneven floor, eliminating at the same time the deformation of the floor. The implementation of flexible elements in the form of a spring also allows for the so-called step back of the housing in cases requiring such a shift.

The subject of the invention is shown in the embodiment in the drawing, in which Fig. 1 shows a perspective view of the casing, and Fig. 2 - a perspective view from the floor side.

The mining housing is located on the front floor 1 and 2 rear floor runner. The bottom plates 1 and 2 are both reinforced with longitudinal supports. Two beams 3 are transversely attached to the brackets. On the bottom plates of the runners 1 and 2, hydraulic supports 4 are articulated, coupled in pairs by a setting device. The device 5 is terminated with two sleeves 6 containing a rubber insert inside and is put on the pins 7 attached to the supports 3. In order to properly attach it to the supports 4, the device 5 has half-clamps put on the outer diameter of the supports 4 and screwed together.

The front floor 1 and the rear floor 2 are connected by two elastic elements 8 made of a spring rolled at its ends and articulated on pins. To step back the housing, a pin must be inserted next to one pivot to prevent lifting. The bottom ridge 2 comprises a cover 9 on the cave side, forming a casing part with the beam 10. The beam 10 is articulated to the canopy 11, and its position is fixed by a hydraulic cylinder 12. The beam 10 overlaps the cover 9 at any height of the casing.

In the front floor 1 under the beams 3 there is a sliding system for sliding the housing. The system comprises a hydraulic cylinder 13 articulated and terminated with a sleeve 14 for connection to the chain conveyor.
