Claims (2)

1. Гидравлическое устройство натяжения болтов, содержащее устройство, образующее первую камеру и вторую камеру, первое полое поршневое устройство, которое перемещается в первой камере и частично продлевается во второй камере, второе поршневое устройство, перемещаемое внутри первого поршневого устройства и во второй камере, причем в указанном втором поршневом устройстве имеется соединительное устройство для соединения с концевой частью болта, и устройство для подачи гидравлической жидкости в упомянутую первую камеру так, что, когда давление гидравлической жидкости прилагается к первой камере, первое поршневое устройство перемещается и, таким образом, это первое поршневое устройство вытесняет гидравлическую жидкость во второй камере и перемещает второе поршневое устройство, которое вытягивает концевую часть болта.1. A hydraulic bolt tensioning device, comprising a device forming a first chamber and a second chamber, a first hollow piston device that moves in the first chamber and partially extends in the second chamber, a second piston device that moves inside the first piston device and in the second chamber, moreover, the specified second piston device has a connecting device for connecting with the end part of the bolt, and a device for supplying hydraulic fluid to said first chamber so that when the hydraulic fluid is attached to the first chamber, the first piston device moves and, thus, this first piston device displaces the hydraulic fluid in the second chamber and moves the second piston device, which extends the end part of the bolt. 2. Гидравлическое устройство натяжения болтов по п.1, в котором в упомянутой первой камере имеется площадь, к которой прилагается давление гидравлической жидкости и которая больше, чем площадь упомянутой второй камеры, к которой прилагается давление гидравлической жидкости. 2. The hydraulic bolt tensioning device according to claim 1, wherein the first chamber has an area to which the hydraulic fluid pressure is applied and which is larger than the area of the second chamber to which the hydraulic fluid pressure is applied.
