(54) ОСНОВАНИЕ СЕКЦИИ МЕХАНИЗИРОВАННОЙ КРЕПИ(54) BASIS OF THE MECHANIZED STRAP SECTION

tt

Изобретение относитс к горному делу, конкретно к креплению очистных забоев механизированными креп ми, секции которых соединены с конвейером.The invention relates to mining, specifically to fixing of mining faces with mechanized supports, sections of which are connected to a conveyor.

Известно устройство дл соединени механизированной крепи с конвейером, содержащее гидродомкрат передвижени , закрепленный на основании секции, имеющей забойный носок, и соединенный с конвейером с помощью рычага, выполненного с упорами и снабженного направл ющими, которые взаимодействуют с забойным носком основани 1.A device for connecting mechanized supports with a conveyor is known, comprising a hydraulic jack of movement fixed on the base of a section having a bottom hole and connected to the conveyor by means of a lever made with stops and fitted with rails that interact with the bottom bottom of the base 1.

Однако такое устройство не исключает заклинивание направл ющих и нагружение щтока гидродомкрата изгибающим усилием .However, such a device does not exclude the wedging of the guides and the loading of the hydraulic cylinder wiper with a bending force.

Наиболее близким к изобретению но технической сущности и достигаемому результату вл етс основание секции механизированной крепи, содержащее продольные балки, св занные поперечной траверсой, соединенную с конвейером направл ющую лыжу, выполненную с фигурным уступом и расположенную между продольными балками , поворотный элемент, установленный между направл ющей лыжей и поперечнойThe closest to the invention but the technical essence and the achieved result is the base of the section of mechanized support, containing longitudinal beams connected by a cross-beam, connected to the conveyor by a guide ski, made with a figured ledge and located between the longitudinal beams ski and cross

траверсой, и поперечную горизонтальную ось 2.traverse, and transverse horizontal axis 2.

Недостатками известного основани крепи вл ютс заштыбовка поворотного элемента , выполненного в виде ролика, и как 5 следствие, увеличенные усили страгивани конвейера.The disadvantages of the known base of the lining are the gagging of the rotary element, made in the form of a roller, and, as a result of this, increased efforts to move the conveyor.

Цель изобретени - уменьщение усилий необходимых дл перемещени конвейера.The purpose of the invention is to reduce the effort required to move the conveyor.

Цель достигаетс тем, что поперечна траверса выполнена с фигурным уступом, а поворотный элемент - в виде щтанги с фигурными концами и закреплен поперечной горизонтальной осью консольно в одном фигурном уступе с возможностью взаимодействи свободного фигурного конца 15 другим фигурным уступом.The goal is achieved by the fact that the transverse traverse is made with a figured ledge, and the pivot element is made in the form of a bar with figured ends and is fixed by the transverse horizontal axis of the cantilever in one figured ledge with the possibility of interaction of the free figured end 15 with another figured ledge.

Claims

FIG. 1 shows the base of the lining section, tightened to the conveyor, side view; in fig. 2 - the same, with the conveyor pushed forward, side view; in fig. 3 shows section A-A in FIG. one; in fig. 4 — lining base when fastening the shtangi with the other end and tightened conveyor; in fig. 5 - the same, with extended conveyor; in fig. 6 shows section A-A in FIG. 5 The base of the mechanized roof support section includes longitudinal beams 1 connected by a transverse cross-beam 2, a guide ski 3 of the conveyor, made with a shaped ledge 4. With a guide ski 3 of the conveyor is connected by a horizontal transverse axis 5 with the lower figure end of the swivel bar 6, which when it is extended, the support section has the opportunity to interact with its upper figured end with the figured ledge from below the transverse yoke 2. A guide element 7 is installed on the yoke for inserting the rotary pole 6 into the bach position The device works as follows. When the conveyor is extended, the swivel rod 6 is located on the ski 3 of the conveyor, and the axis 5 prevents it from shifting. When extending the securing section of the guide element 7, it runs over the upper end of the pivot rod 6, turns it into an inclined working position before the upper end of the pivot rod 6 contacts the figured ledge in transverse traverse 2. The pivoting rod moves the rock mass that has fallen into the area of operation of the device . Acting as a spreader, the bar 6 eliminates the need for manual unscrambling operations. When the yoke 2 is pushed forward and loaded, it is supported by a shaped ledge on the upper end of the rod 6 and transfers part of the rock pressure to the guide ski 3 of the conveyor through the swivel rod 6, abutting the figured ledge 2 on the ski guide 3. When the conveyor is pulled out, the swivel rod 6, fascinated by the axis 5, turns around, slides along the guide element 7, thus forming a gap between the cross-member 2 and the guide ski 3, necessary for normal advancement of the conveyor and its control in a vertical plane. The invention The base of the mechanized support section, comprising longitudinal beams, connected by a cross-beam, a ski guide connected to the conveyor, made to a figured ledge and located between the longitudinal beams, a turning element installed between the ski guide and the cross-member, the transverse horizontal axis , characterized in that, in order to reduce the effort. required for moving the conveyor, the transverse traverse is made with a figured ledge, and the rotary element is in the form of a rod with figured ends and is fixed by the transverse horizontal axis of the cantilevered one figured ledge with the possibility of interaction of the free figured end with another figured ledge.
