Description
,1,one
Изобретение относитс к подземной добыче угл , а именно к креплению очистного забо с номощыо механизированной крепи.The invention relates to underground coal mining, namely to the attachment of a clearing slab with a mechanized support.
Известно устройство дл перекрыти межсекционных зазоров в механизированных креп х , включающее выдвижные кожухи.A device is known for closing off intersectional gaps in mechanized supports, including retractable covers.
Цель изобретени - предотвращение попадани породы в рабочее пространство крепи при ее передвижении на пластах с неустойчивой кровлей.The purpose of the invention is to prevent the rock from entering the working space of the support when it moves on seams with an unstable roof.
Это достигаетс тем, что устройство снабжено жестко закрепленными на выдвижных кожухах продольными стержн ми, св занными между собой серьгами.This is achieved by the fact that the device is provided with longitudinal rods rigidly attached to the retractable covers and connected to each other with earrings.
На фиг. 1 изображено предлагаемое устройство , вид спереди; на фиг. 2 - вид но стрелке Л на фиг. 1; на фиг. 3 - разрез но Б - на фиг. 2.FIG. 1 shows the proposed device, front view; in fig. 2 shows an arrow L in FIG. one; in fig. 3 shows a section but B in FIG. 2
Устройство состоит из выдвижных кожухов /, снабженных жестко закрепленными продольными стержн ми 2, св занными между собой серьгами 3.The device consists of retractable covers /, provided with rigidly fixed longitudinal rods 2, connected with each other by earrings 3.
Устройство позвол ет осуществить независимое передвижение каждой секции относительно друг друга, как в нараллельпом направлении , так и нри перемещении одной из соседних секций вверх или вниз.The device allows independent movement of each section relative to each other, both in the parallel direction and moving one of the adjacent sections up or down.
