SU471455A1 - Mechanized support lava interface with drift - Google Patents

Description

The invention relates to mechanized support of the interfacing of lava with a drift and can be used in the plow mining of coal seams.

The lining of the lava interface with a drift is known, consisting of sections interconnected by power jacks, on the basis of one of which a table for plow drives and a conveyor is fixed. However, these lining is not stable and unreliable in management.

The proposed support is characterized by the fact that, on the basis of another section, a traverse with hinged transverse directions of yush is hinged, and the drive table is made with grooves in which guides are placed. This allows you to ensure the stability of lining and reliability in management.

FIG. 1 and 2 shows the proposed lining, general view; in fig. 3 is a view along arrow A in FIG. 2

The coupling support consists of the outer 1 and inner 2 sections interconnected by power jacks 3. On the basis of the outer section 1 there is a table 4 for plow drives and a conveyor connected by rods 5 to the front and rear carriages 6. On the basis of the inner section 2, the beam is hinged together 7 with hinged transverse guides 8. Table 4 is made

with grooves in which transverse guides 8 are placed.

The jacks 3 fixed on the carriages 6 allow the sections 1 and 2 to move freely one relative to the other in the transverse direction. The position of the tops is corrected by hydraulic jacks 9, which are hinged on the support posts.

The hinged connection of the table with the inner section 2 allows the sections to adapt to the unevenness of the soil, to install the section one relative to another at an angle dictated by the conditions of the notch.

The longitudinal movement of the table 4 with the carriages 6 along the base of the outer section 1 is carried out by the longitudinal jacks 10. Simultaneously with the movement of the table and the carriages, the inner section 2 also moves, since it is connected with the table by transverse guides 8 and the longitudinal cross member 7. Such a connection allows It does not significantly shorten the span between the hydraulic section of the inner section and install them in close proximity to the table.

Subject invention

Mechanized lining of lava 30 with a drift, consisting of sections interconnected by power jacks, on the basis of one of which a table for plow drives and a conveyor is strengthened, characterized in that, to ensure stability of lining and reliability in control, on the basis of another - The 5th section is hinged with a traverse with hinged transverse guides, and the drive table is made with grooves in which the guides are placed.
