Description

"1 The invention relates to mining, in particular to equipment for the mechanization of coal mining in mines from inclined and steep seams. A known unit for excavation of inclined and steep seams, including mechanized lining with a base beam, upper and lower guides, the traverses of which are equipped with double action jacks and plow carriages j mounted on the guides l. The disadvantage of this design is that the reservoir power control is performed manually on each chip by double action jacks, which is very laborious and reduces the aggregate performance. Closest to the proposed coal excavation unit, including sectional mechanized support, connected with the base jacks on the base telescopes are installed to the hydraulic jacks of the control, the executive body, the body of which is connected by axes to the grips interacting with the upper and lower guides ba Shl .2. However, it is impossible to separate the soil and roof, because when tilted to the bumping holoak of the executive body, both the soil and the roof simultaneously approach and the slope to the dam is, on the contrary, a departure from the soil and from the roof; it is impossible to keep track of local changes in the formation hypsometry, and the breakage of telescopes due to a large amount of force from the executive body during coal blasting is not excluded. The aim of the invention is to increase the efficiency of formation hypsometry unit control. This goal is achieved by the fact that in a coal extraction unit comprising sectional mechanized support, connected with the hydraulic jack, the shifting to the base, on the telescopes of which the control hydraulic sleeves are mounted, the actuator body of which is connected with the grippers interacting with the upper and lower base guides, the executive body is made in the form of rotating boring heads, the axes of which are mounted horizontally on the body, coaxially with the core {2 pin to the grippers and perpendicular to the guides, The telescopes of the base are equipped with additional external moving parts, on which lower lower limbs are fixed, while the moving parts of each telescope are connected in a plane perpendicular to the direction of movement of the unit, with a fixed part of the telescope with hydraulic control jacks, the axes of which are perpendicular to the rotation axis of the breaking heads. FIG. 1 depicts the unit; in fig. 2 - the same, side view; in fig. 3 is a section A-A in FIG. 2; FIG. 4 - section bb in figure 2. The unit contains sectional mechanized lining 1, upper 2 and lower 3 guide and executive body 4, Each section of mechanized lining 1 includes upper to 5 and hydraulic post 6 resting on shoe 7, basic beam 8 and fence 9 connected by levers 10 to basic The beam 8. The base beam 8 is a frame structure connected by bolts 11 and has a front 12 and a rear 13 strip. The frame of the base beam 8 serves as a supporting element and guide for the base 7 when moving the lining sections 1. I The movement of the unit is carried out by hydraulic sleeves 14, connected with 13 sections and shoes 7 set by themselves, and hydraulic jacks 15 of movement connected to guards 9 and telescopes 16. Telescopes 16 are mounted on the front section 12 of the base beam 8 through the section and consist of the inner fixed parts 17 rigidly mounted on the front of the cross 12 and the outer securing parts .18 and 19, moved apart by the hydraulic jacks 20 and 21 of the control located inside the fixed part 17 of the telescope 16. To the movable outer parts 18 of the telescopes 1 6, an upper guide 2 is attached, and to the outer movable parts 19, a lower guide 3. An upper 2 and a lower 3 guide consist of separate segments interconnected. The hinge.3. The executive member 4 has rotating jacking heads 22 and 23 mounted on the housing on horizontal axes 24 and 25. The executive member 4 is provided with grippers 26 and 27 for engagement with the upper 2 and lower 3 guides. The body of the actuator 4 is connected to the grippers 26 and 27 by means of axes 28 and 29 located perpendicular to the guides 2 and 3 and coinciding with the axes of rotation 24 and 25 of the jack heads 22 and 23. The drive of the jack heads 22 and 23 can be placed in case grippers 27 or in the body of the executive body 4. The unit operates as follows. Before removing the first chip and when removing the unit from the assembly chamber with hydraulic jacks 20 and 21 of the control, which have separate control, the outer parts 18 and 19 are moved. The guides 2 and 3 connected to them are adjusted so that the end heads 22 and 23 covered the seam thickness. When the guides 2 and 3 are moved, the grippers 614 26 to 27 interact with them, and the body of the executing body 4 connected to the latter by means of axes 28 and 29 rotates parallel to the bottom of the chest until it touches the jack heads 22 and 23, respectively, of the roof and the formation soil. After adjusting the actuator 4, it is supplied to the bottom by means of hydraulic jacks 14 and 15 and the belt is worked out equal to the width of the baffle heads, which, moving along the bottom, follow the directional profile. When the formation hypsometry changes, the profile of the guides is corrected by hydraulic jacks 20 and 21. The lining sections are moved successively, following the working of the tape or in groups, then the cycle repeats. Such an implementation of the unit allows the body of the executive body to swing in the bottom plane and effectively control it by hypsometry of the formation separately on the soil and roof, it is also possible to work layers with hard coal and hard rock inclusions, while ensuring the reliability of the control system protect jacks telescopes sliding against the effects of transverse bending loads during blasting angle.
