Title (EN) HYDROHAMMER
(FR) MARTEAU HYDRAULIQUE
(RU) ГИДРОМОЛОТ
Abstract: front page image
(EN)The invention relates to the mining and construction industries and is designed to increase the operating efficiency of a hydrohammer and simplify the design thereof. The indicated technical result is a hydrohammer, which comprises a pressure line and a drain line, a body with a hammer head fitted therein, a hydraulic power accumulator with hydraulic cavity and plunger located in the upper part of the body, the hydraulic power accumulator being in axial alignment with the hammer head, and where the end face of the plunger in operating condition, at the end opposite to the hydraulic cavity, is designed to be able to abut against the upper end face of the hammer head.
(FR)L'invention concerne l’industrie minière et des matériaux de construction et vise une meilleure efficacité de fonctionnent d’un marteau hydraulique et une simplification de sa conception. Le résultat technique consiste en ce que ce marteau hydraulique comprend une conduite principale d’injection et d’évacuation, un corps dans lequel est monté un percuteur; sur le même axe que ce dernier, dans la partie supérieure du corps, est monté un accumulateur d’énergie hydraulique muni d’un récipient hydraulique doté d'un piston, et l’extrémité du piston en mode actif du côté opposé au récipient hydraulique est capable de buter contre l’extrémité supérieure du percuteur.
(RU)Изобретение относится к горной и строительной промышленности и направлено на повышение эффективности работы гидромолота и упрощение конструкции. Указанный технический результат в гидромолоте, содержащем напорную и сливную магистрали, корпус с установленным в нем бойком, соосно которому в верхней части корпуса расположен гидравлический аккумулятор энергии с гидравлической полостью с плунжером, торец плунжера в рабочем состоянии со стороны противоположной гидравлической полости выполнен с возможностью упора в верхний торец бойка.
