Description

one

The invention relates to mining, in particular to mechanized fasteners designed for LD-I of the fastening of mine workings.

The purpose of the invention is to increase the number of lining sections when moving them.

Figure 1 shows the lining, side view; figure 2 - the same plan; in FIG. 3, view A in FIG. 1; figure 4 - section bb in figure 1.

The coupling support includes the middle 1 and extreme 2 sections. Middle section

The reinforcement consists of a carriage 3 with grooves 4, on which hydroracks 5 are installed with guides 6 under the longitudinal beams 7 of the outer sections 2 of the support, the hydroracks of the latter 8 are located in the same plane with the corresponding hydroracks 5 of the middle section. Each hydraulic post 8 is mounted on support plates 9, each of which and - 1 has a hinge connection 10 with the end portions of the guide beams

11 entering the longitudinal grooves 4 of the carriage 3. Each guide beam

I1 is connected to the carriage 3 by the hydraulic jacks 12 before the liquefaction on both sides. On the carriage 3, the transverse guides 13 are fastened. To install the drive 14 of the lateral conveyor 15. The gaskets 16 are designed to provide the rails of the longitudinal beams for guiding the hydraulic struts of the middle support section.

To enable the use of lining in workings with various forms of execution, springs 17 are provided for each hydrorail 8 and elements 18 in the attachment of hydroracks 5 and B.

To carry out the adjustment of the position of the interface in relation to the excavation in the construction of a crepe, hydraulic jacks 19 are provided.

The support works as follows.

The initial position - the conveyor 15 is pushed up to the chest of the clearing face, after which it is necessary to move the support in the direction of the clearing recess. For this purpose, the hydraulic posts 5 of the middle section of the lining 1 are unloaded and the gasket 16 is removed from under the longitudinal beam 7. Then these hydraulic legs are again burst, but so that between the guide 6 and the longitudinal beam 7

tuls gap. Next, hydrostatic unloading is performed at 8 extreme sections 2 of the lining until the longitudinal interaction

 beams 7 with a guide 6 hydro stands 5 of the middle section 1. support.

When the rear and front hydraulic jacks 12 are turned on, the guide beam 11 moves relative to the longitudinal grooves 4 of the carriage 3. Simultaneously with the beam 11, the hydraulic posts 8 of the end section 2 with the longitudinal beam 7 mounted on them also.

15 of the extreme section 2 is made its spread.

The process of moving the second extreme section 2 is similar to moving the first extreme section 2 of the support. As a result, the lining is prepared for shifting the drive 14 of the main conveyor 15. for which it is necessary to unload all hydraulic racks 5 of the middle section 1 of the lining, turn on all hydraulic jacks 12 for simultaneous operation, and then spread the middle section 1 of the lining.

The direction of movement of the carriage 3 is guaranteed by the guiding beams 30, 11 with respect to which the carriage 3 moves, and by the presence of the guides 6 on the hydraulic legs 5 of the middle section 1 of the support.
