The invention relates to a travelling machines used for construction and repair of railway tracks, in particular to the travel machine for tamping ballast layer, alignment and stabilization of the path.
Famous modern lining, tamping, stabilizing machine continuous Dynamic Stopfexpress" 09-4, produced at the present time the firm "Plasser &Theurer Austria, contains two sections that are installed on the track: a section for alignment and tamping the path containing the main frame, supported on the undercarriage drive continuous work of moving and carrying extra frame mounted between the chassis trucks main frame with the possibility of cycle set on it tamping Assembly for tamping ballast under sleepers rail and lifting and leveling Assembly for alignment the horizontal and vertical planes, directly behind the section for alignment and tamping path provided by section to stabilize the path containing the frame resting on the undercarriage, and mounted on the frame with the possibility of working jointly move with her stabilizing unit (Prospect machine "Dynamic Stopfexpress" 09-4X" company "Plasser &Theurer Austria).
The main disadvantage of this machine is to reduce the effectiveness of stabilisierung the unit when the speed fluctuation of the working travel of the machine and need to change the parameters of a dynamic impact on the way especially in the period of change of the operating cycle tamping unit due to the large inertial moments of the stabilizing Assembly.
A known machine for tamping and stabilization of the railway, specified in method of tamping and stabilization of the track, which was adopted as a prototype, containing a machine frame supported chassis trucks with traction drive on the track with the rails mounted on the machine frame between the directional trolleys spelaeogriphacea unit for simultaneously tamping two adjacent ties and located in front of sporopollenin unit lifting and straightening unit. Directly behind the machine frame is provided for stabilizing the vehicle with the frame resting on the undercarriage, which has its front end connected by a hinge with the machine frame. In the center between the hinge and driving trucks on the frame stabilizing the vehicle rigidly fixed stabilizing unit. The hinge on the machine frame is located for movement stabilizing the vehicle with the stabilizing unit in a longitudinal direction relative to the machine frame drive longitudinal movement to maintain a constant duration of an operation stabilization path (RU, patent No. 2143512, CL. EV 27/20, 1999).
The disadvantages of zvetnoi machine for tamping and stabilizing rails are rigid stabilizing unit for stabilizing frame of the vehicle with a large joint mass and inertia, resulting in the change of the operating speed or stops during a working movement of the machine to the formation of defects alignment track and reduce the efficiency of the machine in a working mode of operation, and special arrangements fixation stabilizing the vehicle with the machine frame is a reduction in the reliability of the machine in transport mode.
The technical result of the invention is to increase machine efficiency by providing movement of the stabilizing Assembly relative to the frame stabilizing the vehicle and reduce defects alignment rail and improving the reliability of operation of the machine by eliminating the special mechanisms of the fixing roll of the vehicle with the machine frame.
This technical result is achieved by a machine for tamping and stabilization of railway track containing a machine frame supported chassis trucks with traction drive rail way sleepers installed between the chassis trucks spelaeogriphacea unit for compressing sleepers and located in front of sporopollenin unit lifting and straightening unit mounted directly behind the engine frame stabilizing the vehicle with the frame resting on the undercarriage, which, with its front to ncom connected with the machine frame, between running the trucks frame stabilizing the vehicle has a stabilizing unit stabilizing frame of the vehicle includes longitudinal rails with the carriage, roller bearings installed on the longitudinal guides, a stabilizing unit is installed on the carriage can move in the longitudinal direction relative to the frame stabilizing the vehicle by the drive to maintain a constant duration of an operation stabilization path.
