(54) DEVICE FOR INSTALLATION OF MECHANIZED STRAP SECTIONS

one

The invention relates to mining, specifically to means of mounting and dismounting mechanized roof supports on steep seams.

A device for mounting mechanized roof supports is known, which contains a traction winch, an accumulating winter track roller and angled guides installed in lava 1.

The disadvantage of this device is a large amount of preparatory work prior to installation or disassembly.

The closest to the invention to the technical essence and the achieved result is a device for mounting sections of mechanized support, comprising a pull winch and means of transporting sections through the mounting chamber 2.

A disadvantage of this device is the need to perform in the mounting chamber a considerable amount of operations to turn the sections and the need for the operating personnel to be located in the immediate vicinity of the place where these operations are performed, which reduces the safety conditions of the work.

The purpose of the invention is to reduce the labor intensity and increase the safety of the execution of works.

This goal is achieved by the fact that the means of transporting sections along the mounting chamber are made in the form of hydrocrats paired with hinged attachment points for installation between the ceilings and the bases of each two adjacent sections. FIG. 1 shows schematically the descent of a section into the mounting chamber with

to devices for installation, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - raising the section from the dismantling chamber with the help of a device for mounting, plan view; in fig. 4 shows a section BB in FIG. 3. A device for mounting mechanized support sections consists of two-sided mounting hydraulic jacks 1 having hinged attachment points 2 at the ends, which connect the hydraulic jacks to the overlaps 3 or bases 4 of each adjacent sections 5 of the support. The hinge attachment points have a hinge in the plane of the formation and in the plane normal to the formation. Each two adjacent sections 5 are interconnected by four mounting jacks 1 (two floors and two bases). Mounted sections of the support have hydraulic posts 6 and protective shields 7 installed between bases 4 and non-openings 3. When removing the supports from the lower side of the protective shields 7, a backfill pipe 8 with a telescopic device is installed. The ventilation winch is equipped with a winch for transporting the lining sections by clamp. Device for mounting support works as follows. With the help of a winch, section 5 of the lined support is pulled on the ventilation flap to the place of its descent into the mounting chamber. The first section is located in the mounting chamber by means of a traction winch below the soil of the ventilation slider adjacent to it, hydraulic supports 6 are included in the hydraulic support system, and the section is spread. Thereafter, the next section 5 is pushed towards the place of descent into the mounting chamber. The mounting jacks 1 and the legs 6 are included in the hydraulic system and the section is spread. The mounting jacks 1 are attached by the hinge joints 2 to the ceilings and bases of both sections. Further, below the first section 5 in the mounting chamber, wooden lining is removed to the width of the lining section; the size of the hydraulic jack shchaga equal to the width of section 5 of the support. After that, the displaced section is thrust between the roof and the ground, the next section is unloaded and moved down, supplying the working fluid to the plugs of the hydraulic jacks 1 and connecting their pressure cavities to the drain. Then, the next section 5 is pulled down to the place of descent into the mounting chamber in a described manner, dropping down onto the installation shaft located in the support section camera and descending into the section chamber located on the ventilation drift. After all the mechanized lining sections have been lowered, the rest of the hydraulic system of the mechanized lining and communication elements between the sections are installed. The dismantling works are performed in the reverse order. As the lining sections are removed, the removal chamber is laid through the backfill pipe 8, which is shortened with a telescopic device as the space developed (the removal chamber) is laid out. The use of the proposed device increases productivity, reduces the laboriousness of the assembly and disassembly work and the equipment used in this invention. Formula for mounting mechanical support sections, including a pull winch and means for transporting sections through the assembly chamber, characterized in the safety of the work, the means of transporting the sections along the mounting chamber are made in the form of paired hydraulic jacks with hinged nodes E attachment for setting the overlap between E and bases of each two adjacent sections.
