Description

Изобретение относитс  к горной промышленности . Известно упоро-выравниваюи ее устройство дл  предотвращени  сползани  крайней лавкой секции, включающее гидроцилиндр, установленный в гнездах щек кронштейна основани  штрековой крепи. Известное устройство неудобно тем, что оно не обеспечивает надежного удержани  крайней лавной секции от сползани  в подрывку штрека, а потому стопоренис основани  секций производитс  унором дерев нной стойки в борт плтрека. В предлагаемом устройстве гидроцилиндр помещен в обойму, снабженную цапфами, вход щими в гнезда щек кронштейна. Щеки кронштейна могут быть выполнены с отверсти ми , а обойма снабжена стопором. На чертеже изображено предлагаемое устройство в двух проекци х. Устройство состоит из гидроцилнндра 1, обоймы 2 с цапфами 3 и стопором 4, и кронштейна 5. Кронштейн 5 выполнен в виде щек 6 и 7, которые имеют гнезда 8 и 9. Щеки кронштейна выполнены с отверсти ми 10. Направл юща  обойма, кача сь на цап (, фиксируетс  посредством стопора в нужном но высоте направлении. Г1 дроцилиндр выдвигаетс  до упора опорной лыжи // в основание 12 лавиой секции. Нередвижка как лавной секции, так и крепи сопр жени  13 производитс  с посто нным контактированием oHopHoii лыжи с основанием лавной секции. Н р е д М е т изобретени  1.Упоро-выравкивающее устройство дл  предотвращени  сползани  крайней лавиой секции, включающее гидроцилиндр, установленный в гнездах щек кронштейна основании штрековой крепи, отличающеес  тем, что, с целью обеспечени  надежной работы устройства , гидроцилиндр помещен в обойму, снабженную цапфами, ВХОДЯЩИМИ в гнезда щек кронштейна. 2.Устройство по п. 1, отличающеес  тем, что, с целью фиксации устройства в заданном положении, щеки кронштейна выполнены с отверсти ми, а обойма снабжена стопором.The invention relates to the mining industry. It is known to resist leveling it to prevent the section’s extreme bench sliding, including a hydraulic cylinder mounted in the slots of the cheeks of the ground support bracket. The known device is inconvenient in that it does not ensure that the extreme section of the section is reliably prevented from slipping into the drift run-up, and therefore, the stopper of the base of the sections is produced by wearing a wooden stand into the board of the deck. In the proposed device, the hydraulic cylinder is housed in a holder provided with trunnions entering the sockets of the cheeks of the bracket. The cheeks of the bracket can be made with holes, and the clip is provided with a stopper. The drawing shows the proposed device in two projections. The device consists of a hydrocylinder 1, a clip 2 with pins 3 and a stopper 4, and a bracket 5. The bracket 5 is made in the form of cheeks 6 and 7, which have slots 8 and 9. The cheeks of the bracket are made with holes 10. on the stud (fixed by stopper in the desired but elevated direction. G1 cylinder rotates up to the abutment of the supporting ski // into the base 12 of the lion section. Non-movement of both the main section and the lining of the interface 13 is performed with constant contact of the oHopHoii ski with the base of the main section Invention 1. Depression A protective device for preventing the extreme lavi section from slipping, including a hydraulic cylinder mounted in the nests of the bracket cheeks to the base of the lintel, characterized in that, in order to ensure reliable operation of the device, the hydraulic cylinder is placed in a yoke provided with trunnions INCLUDING in the nests of the bracket cheeks. Item 1, characterized in that, in order to fix the device in a predetermined position, the cheeks of the bracket are made with holes, and the clip is provided with a stopper.
