DEVICE FOR MOUNTING MINE MECHANIZED HOUSINGS

Claims (2)

Patent claims 1. A device for the assembly of mining mechanical supports with a sub-torture chamber, hydraulic lifts with tubular supports and a load-bearing base, the hallmark of the fact that below the runway / 1 / there is a track-stop chamber / 2 /, on the bottom of which there is a bearing plate / 3 /, on which are mounted symmetrically arranged feet of the lift / 4 / on which are mounted pi ^ i ^ i ^ and ^ o hydraulic jacks / 5 / with attached tubular supports / 6 / on which the supporting base is installed / 7 / with a length greater than the length of the transport platform / 9 / ', but less than the length of the mounting plate / 10 /, the section of the movable track / 8 / placed on the supporting base / 7 / being a continuation of the runway / 1 /. 2. The device according to claim 1, characterized in that between the supporting base / 7 / and the supporting plate / 3 / stabilizing supports are installed, and on the walls of the supporting chamber / 2 / there are guide rails on which rollers move along the sides of the supporting base / 7 / . The subject of the invention is a device for the assembly of mining supports at the bottom of the mine, the joint of the hydraulic support section. Currently, the assembly and disassembly of the powered support sections at the bottom of the mine took place on stands equipped with a sliding assembly plate located on the tracks and limited transversely against displacement. Transport of the assembled section of enclosures between the assembly stand and the partition wall took place on the transport platform. The loading of the section onto the transport platform and its unloading was carried out with the use of the structure of the loading sill, the wheels and the suspended monorail. A basic element of the currently used thio-tying is the costly and labor-intensive loading and unloading operations. They are related to the necessity to move the sections weighing several tons vertically and horizontally, which therefore extends the time spent on assembly work. The aim of the invention is to eliminate the problems associated with the necessity to load the sections onto the transport and unloading platform. The essence of the oyMiazek is the device for assembling the mining mechanized supports on the transport platform, located in the support chamber below the track. At the bottom of the pfdtfrooej chamber there is a support plate on which are mounted symmetrically spaced elevator feet. On the feet of the lift, vertical supports are mounted for hydraulic carriers, on which tubular slides are placed. A load-bearing base is mounted on the hydraulic lifts, the length of which corresponds to the length of the track chamber and is greater than the length of the transport platform, but smaller than the length of the deck. There is a movable track section on the support base, which is a continuation of the runway. It is advantageous if, for the stabilization of the supporting base, additional stabilizing supports are mounted between it and the supporting plate, and guide rails are arranged on the side walls of the track chamber, cooperating with rollers installed on the sides of the supporting base. The subject of the invention is illustrated by an example of the implementation in the drawing, which shows a device for assembling roofed mining supports with a view and a side section. Below the runway 1 there is a rectangular subtrack chamber 2. The horizontal bearing plate 3 in the form of a sandstone-gravel oylea covers the bottom of the track chamber 2. In the bearing plate 3 are embedded four symmetrically spaced rectangles, the hoist feet 4. The hoist feet are connected with them. 5 hydraulic jacks on which they are attached 157 537 aa tube guides 6. A rectangular support base 7 is mounted on the hydraulic jacks 5, the dimensions of which are adapted to the surface of the track chamber 2. On the support base 7 there is a movable track section 3, which is a continuation of the carriageway 1. The length of the support base 7 and The moving track section 8 is greater than the length of the transport platform 9, but less than the length of the mounting plate 10. The transport platform 9 with the mounting plate 10 placed on it is rolled along the track 1 and positioned on the moving track section 8. Hydraulic jacks 5 make it possible to lower the base support 7 with the transport platform 9 so that its surface is at the level of the runway 1. This enables or disassembly of the ooud section j on the mounting plate 10 directly on the transport platform 9. After completing the work, lifting the support base 7 it is possible to equalize the section K of the running track 8 e with the level of the runway 1 Connecting the transport platform 9 to the runway 1. Tubular guides 6 protect the transport platform 9 against movements in the horizontal plane.
