Description

The present invention relates to railway transport, namely track machines.

A track machine is known, comprising a frame mounted on running bogies and working bodies representing bucket rotors, trusses are mounted on the sides of the machine frame, one of the supports of which is pivotally mounted on the frame, and the other is connected to the frame of the machine by a traction of variable length. Axles are installed between the supports of the truss, and the bearing frames of the rotors are connected by means of rotation cylinders to the truss / 1 /.

To ensure large rotor removal, very long traction is required. Due to the location of the conveyor on the farm and the use of long traction, the design of the track machine is complicated.

The fastening of the trusses to the frame using power cylinders and rods complicates the manipulation of the rotor, since when the hydraulic cylinder is extended, the rotor, limited by the rod, moves in two planes due to the interconnection of horizontal and vertical movements.

The impossibility of folding the structure into transport position in case of failure of the hydraulic cylinder at large distances from the track axis without additional powerful beam cranes is also a design flaw.

The basis of the invention is the solution of the problem: expanding the functionality of the machine by providing a large distance of the rotor from the axis of the path, increasing the reliability of the machine by providing emergency lift of the rotor at a great distance from the axis of the path, simplifying the design of the machine and simplifying the management of rotors by eliminating large traction lengths and exceptions for installing a hinged hydraulic cylinder.

This is achieved due to the fact that the track machine, containing a frame on the undercarriage, on which rotors are mounted that are moved by lifting and turning power cylinders, and the sides of the frame on each side are equipped with trusses pivotally mounted on it, made with the possibility of separate lifting and pivotally pivotally interconnected and connected by a lifting power cylinder, while the lifting truss is located on a turning cylinder connected to the machine frame.

The invention is illustrated by drawings, where figure 1 shows a General view of a track machine; figure 2 is a General view of the track machine from above in the direction A indicated in figure 1. The positions in the drawing indicate: frame - 1, running trolleys - 2, rotors - 3, drive - 4, lifting trusses - 5, rotary trusses - 6, lifting cylinders - 7, turning cylinders - 8.

The crushed stone cleaning machine contains a frame 1 mounted on running trolleys 2, devices for cutting ballast in the form of rotors 3, a drive 4, lifting trusses 5, rotary trusses 6, lifting rams 7, turning cylinders 8.

The machine works as follows: bucket rotors 3 with the help of cylinders 7 and 8, which control the movement of trusses 5 and 6, are retracted to the sides, lowered to the required depth and turned to the required angle (depending on the work performed). In this position of the rotors 3, the ballast is cut out and dumped when the conveyor of the rotor is reversed along the trench to any of its sides or fed to the conveyors of the machine.

The transfer of rotors to the transport position is carried out as follows: the rotor 3 rises from the trench and is brought to the machine on the farms 5 and 6 using the same power cylinders 7 and 8. In case of cylinder failure, the most difficult part of the job is to lift the rotors from the trench at a great distance from the axis of the machine, if there is a rotary truss in the structure, which is the base of the lifting truss, is solved without any crane beams, jibs, hoists, etc. - just a jack installed between these trusses, which greatly simplifies the design and reduces metal consumption. The rotation of the trusses 5 and 6 with the rotor in the raised position by rotation on the loop is possible both manually and by storing for the second rotor.

The track machine of the proposed simplified design will significantly improve the reliability of the machine and simplify the elimination of emergency situations, especially at large distances of the rotor from the axis of the track.
