Description

(54) MECHANIZED COMPLEX

one

The invention relates to mining, in particular to mechanized crepe and cleaning faces, and can be used in the integrated mechanization of cleaning work on steep seams.

Known mechanized lining, containing two-post sections, a system of telescopic links and a base element in the form of a cable, mounted on the End sections 1.

However, during the movement of sections of this support there is an accumulation of errors in their spatial position, which reduces the performance of the complex.

The closest to the proposed technical rectification is a mechanized complex that includes lining sections installed between the guiding beams of the base element, on which hydroins are installed a pair of telescopic pivot links, and the bases are connected to the base element by means of mobile hydraulic jacks 2.

The disadvantage of this complex is the presence of a continuous chain of telescopic links along the entire length of the lining and placement between the bases of all sections of the guide beams, which, in case of inaccurate alignment of the sections to the final position, leads to an intensive accumulation of errors both in the direction of the strike and on the rise of the reservoir.

The purpose of the invention is to increase the accuracy of orientation of the support sections in the process of movement.

10 The goal is achieved by the fact that the sections are combined into groups, and the guide beams are made with bevels towards the dam on the side of the overlying section and are connected to the base element by means of sliders installed with

15 is moved along it by means of hydraulic jacks, while the base in the bottom of the section group is provided with a collar and a support for interacting with the guide beam.

Claims (2)

In addition, the clamps are made of sharpened four-links and installed in the bases by means of pivots that can be rotated around an axis perpendicular to the longitudinal axis of the section. FIG. 1 shows a complex, general view; in fig. 2 is a section A-A in FIG. 1. The mechanized coal complex includes mechanized lining with sections of the same type 1 containing hydrorests 2, bases 3, overlap 4, swiveling telescopic links 5, jointly connected with hydrorests 2, hydraulic jacks 6 moving, mounted on bases 3 and associated with sliding parts with the base element 7, located on the bottom side of the lining. The base unit is movably connected to the excavation mechanism 8 by means of grippers 9. Between groups of lining sections, including each, at least four sections 1, interconnected by telescopic links 5, guide beams 10 are mounted, which are connected to base element 7 by means of slide blocks 11 with hydraulic jacks 12 installed parallel to the longitudinal axis of the base element 7 and freely placed in clamps 13 fixed on the bases 3 on the side facing the underlying sections. The lateral sides 14 of the guide beams 10 reversed nnye overlying sections to m 1 have bevels in the dammed side rows of hydraulic Ho.muty 2. 12 formed as scharnirnyh quadrilateral and are provided with trunnions 15 installed in the base 3 x axis with the possibility of free rotation, lane pendikul molecular longitudinal axis of the section. From axial movement, the trunnion 15 is fixed by the fastening element 16. The horizontal position of section 1 on the inclined side 14, of the guide beam 10 is provided with a support 17, fixed on the base 3. The complex works as follows. The base element 7, which is prevented from slipping by the clamps 13, in which the guide rails 10 are moved, is moved by the movement jacks 6 to the slaughter together with the excavation mechanism 8 to the impoverishment prepared for it by self-cutting. In this case, gaps S are formed between the inclined lateral sides 14 of the guide beams 10 and the support surfaces of the clamps 13 and the supports 17. All lining sections are displaced between the lateral rocks during the movement of the base element 7. Following the movement of the working excavation mechanism 8 from the bottom up, the section 1 is sequentially moved. The lower section of each group is based on the guide beam 10. All sections of the group pushed away from it are guided by telescopic connections 5. If any section is faulty to the final position due to the dip of the formation, for example, due to the non-detachment of the telescopic links 5 or the deviations of the sections from the horizontal position, these faults are not transmitted to the clipping gaps the sections and the gaps h between the groups of sections, since the telescopic links 5 which are absent in these places do not impose restrictions. After removing the coal strip along the entire length of the lava and moving all sections of the support, the excavation mechanism 8 is lowered along the road to its original position, after which the next excavation cycle is repeated in the order described. To raise the support and the base element 7, if necessary, the following operations are performed. After the base element 7 is moved to the bottom for the next excavation cycle, the lower end hydraulic cartridge 12 is turned on, which raises the guide bar 10 through the slide 11, selects the clearance S. Thereafter, the hydraulic lock 12 is locked with a hydraulic lock. Then the sections of this group move sequentially from bottom to top, copying the amount of lift of the guide beam. All other section groups are raised in a similar manner. After all guiding beams 10 and sections 1 are lifted, the base element 7 is lifted. To do this, hydraulic cartridges 12, which move the base element 7 upwardly relative to the guide beams 10 basted into sections 1, simultaneously turn on. eliminate the accumulation of stepping and angular errors in the links of the kinematic system, orienting the lining of the reservoir uprising, and, consequently, eliminate the unproductive costs of eliminating the consequences of insertion of sections, to improve the accuracy of the orientation of the support sections relative to the base element. Claim 1. Mechanized complex, including lining sections installed between guide beams of the base element, on which hydraulics are installed a pair of telescopic swivel links, and the bases are connected to the base element by means of movement hydraulic jacks, characterized in that in order to improve the accuracy of section orientation the supports in the process of moving, the sections are combined into groups, and the guide beams are made with bevels towards the dam from the side of the overlying section and are connected to the base element th through sliders mounted for movement therealong by means of hydraulic jacks, said base section is provided with a bottom in the group and the support yoke . and interacting with the guide beam. 2.
