    The apparatus consists of a supporting body (7) which can be put onto the flange of the cover (2) in a vertically adjustable manner and of clamping and releasing units, mounted on the supporting body (7), for the stud bolts (6) and fastening nuts (6.2) forming the cover bolting. When the apparatus is put on, drive pinions (9) of a rotary nut drive (10) engage in the external teeth (6.5) of the fastening nuts (6.2), and the free stud-bolt ends are coupled to gripping bodies (12). Furthermore, hydraulic clamping cylinders (13) are provided for axially extending the stud bolts (6) by axially loading the gripping bodies (12) via servo piston (13.1) during the unscrewing and tightening of the fastening nuts (6.2). The latter together with their stud bolts (6) can be unscrewed and removed with the apparatus. The clamping and releasing units are here provided with lifting and bearing means (15, 16), which can be controlled in engagement with regard to the stud bolts (6), in order to form a rotatable bearing arrangement relieving the weight for the thread turns, allocated to one another, of the stud bolts (6) and the pressure vessel, and, in addition to the rotary nut drive (10), the clamping and releasing units have a rotary drive (17) which can be brought into frictional engagement with the stud bolts (6). With this apparatus, it is possible to release not only the fastening nuts but also the stud bolts and then remove the entire cover bolting. <IMAGE>

    The invention of OTE-USES is to mechanized devices and can be used in industry: 1: 1 for building and disassembling threaded connections of scientific research institutes in the form of: i-files with nuts for fastening the cores of high-pressure reactors, mainly nuclear reactors,
    A device for assembling and disassembling threaded connections in the form of studs with nuts for fastening KpbUjjeK high-pressure vessels, mainly nuclear reactors, includes a housing, a nut for gripping the stud, and drives mounted on the housing for stretching the stud, rotating the fastening and catch nut 1.
    The disadvantage of this device is that the assembly and disassembly of threaded connections are performed in a certain sequence, moving the device from one threaded connection to another in order to avoid unsymmetrical loading of the lid and the body of the high pressure vessel, which takes relatively much time for its operation.
    The closest to the proposed technical entity is a device for assembling and disassembling threaded connections in the form of studs with nuts for fastening the rats of high-pressure vessels, mainly nuclear reactors, comprising a housing, a nut with a shoulder for gripping the stud and located on the housing drives for stretching the stud , rotating the fastening nut and the collar nut 2.
    A disadvantage of the known device is that the disassembly and assembly of the threaded connection in order to avoid unsymmetrical loading of the lid and the pressure vessel body takes a lot of time, and the technological operations are carried out only by the clamping and fastening nuts, and another device is required to remove the studs.
    The purpose of the invention is to improve the operating conditions.
    This goal is achieved by the fact that the device is equipped with mechanisms installed on the housing for rotating and lifting the stud, a lead ring with protrusions and grooves rigidly fixed to the pin and connected to the mechanism of the rotating pin by means of a connecting element, - made in the form of an FS spring-loaded in axial Direction} of the one installed in the case with a capacitance and with a possibility; pto} zorota :: the region of its axis is driven with internal and external serrated cuts, the first of which is: 5 interacts with protrusions and notches of the POEED col1:) Ca, and the second - with the Pg) and a driving element of the STEP rotation mechanism, and fur Axial C5 is installed in the casing and at the same time / as before with the process of stretching the saw blade and scoring: ol; en ;; 1t, g: -5DrOdilindr with nopuineM, in-line; -p.iG f5yj.)
