Description

Изобретение относитс  к строительству трубопроводов , в частности к головкам дл  бестраншейной прокладки труб методом продавливани . Известны головки, включающие корпус с кольцевой режущей кромкой, переходный конус , лоток и ролик дл  троса. С целью улучшени  прохода грунта через головку в предлагаемой головке переходный конус смонтирован на подщипниках и выполиен с лопаст ми, закрепленными на нем под углом к продольной оси головки дл  обеспечени  самовращени  последней. На чертеже изображена предлагаема  головка дл  бестранщейной прокладки труб методом продавливани . Она включает переходный конус 1, лоток 2 и ролик 3 дл  троса. Переходный конус 1 смонтирован на подщипниках 4 и 5 между режущей кромкой 6 и корпусом 7 головки. На наружной поверхности конуса 1 под углом к продольной оси головки размещены лопасти 8. К выходному отверстию конуса жестко присоединена подвижна  цилиндрическа  часть 9 лотка, неподвижна  часть 10. которого соединена с корпусом 7. Головка работает следующим образом. Усилие через продавливаемую трубу 11 передаетс  на конус 1 головки, при поступательном движении которой режуща  кромка 6 прорезает грунт, а переходный конус 1 вращаетс  за счет лопастей 8, установленных под утлом к оси головки. Грунт, поступающий внутрь головки, проходит через вращающийс  переходный конус и сбрасываетс  на неподвижную часть 10 лотка. Предмет изобретени  Головка дл  бестранщейной прокладки труб методом продавливани , включающа  корпус с кольцевой режущей кромкой, переходный конус, лоток и ролик дл  троса, отличающа с  тем, что, с целью улучщени  прохода грунта через головку, переходный конус смонтирован на подщипниках и выполнен с лопаст ми, закрепленными на нем под углом к продольной оси головки дл  обеспечени  самовращени  последней.The invention relates to the construction of pipelines, in particular to trenchless pipe laying heads. Known heads include a housing with an annular cutting edge, a transition cone, a tray and a roller for a cable. In order to improve the passage of soil through the head in the proposed head, the transition cone is mounted on sub-supports and spliced with blades fixed on it at an angle to the longitudinal axis of the head to ensure self-rotation of the latter. The drawing shows the proposed head for the trenchless pipe punching method. It includes a transition cone 1, tray 2 and roller 3 for the cable. The transitional cone 1 is mounted on the supports 4 and 5 between the cutting edge 6 and the head housing 7. On the outer surface of the cone 1, the blades 8 are placed at an angle to the longitudinal axis of the head. A movable cylindrical part 9 of the tray is rigidly attached to the outlet of the cone, the fixed part 10. of which is connected to the body 7. The head works as follows. The force through the pressed pipe 11 is transmitted to the cone 1 of the head, with the forward movement of which the cutting edge 6 cuts through the ground, and the transition cone 1 rotates due to the blades 8 installed under the core to the axis of the head. The soil entering the inside of the head passes through a rotating transition cone and is dropped onto the fixed part 10 of the tray. The subject of the invention. A die for pushing a pipe without pipe piercing, comprising a housing with an annular cutting edge, a transition cone, a tray and a cable roller, characterized in that, in order to improve the passage of soil through the die, the transition cone is mounted on liners and made with blades mounted on it at an angle to the longitudinal axis of the head to ensure self-rotation of the latter.
