Abstract
Изобретение относитс к горной и строительной технике и может быть использовано при бестраншейной прокладке коммуникаций дл забивани труб в грунт. Цель изобретени - повышение эксплуатационной надежности за счет уменьшени интенсивности износа корпуса. На переднем направл ющем по се ударника 2 установлена жестко цилиндрическа втулка 10. Продольные пазы в переднем направл ющем по се дл прохода в камеру 8 выполнены под втулкой 10. При подаче сжатого ввоздуха по шлангу 12 ударник 2 совершает возвратно-поступательное перемещение в корпусе 1. Втулка 10 предохран ет корпус 1 от перенапр жений в местах взаимодействи кромок пазов с поверхностью последнего, что снижает интенсивность его износа. 3 ил.The invention relates to mining and construction equipment and can be used in trenchless laying of communications for plugging pipes into the ground. The purpose of the invention is to increase the operational reliability by reducing the intensity of wear of the housing. A rigidly cylindrical bushing 10 is mounted on the front guide over the striker 2. Longitudinal grooves in the front guide over the cross section for passage into the chamber 8 are made under the sleeve 10. When compressed air is fed through the hose 12, the impactor 2 makes a reciprocating movement in the housing 1. The sleeve 10 protects the housing 1 from overvoltages at the points where the edges of the grooves interact with the surface of the latter, which reduces the intensity of its wear. 3 il.
