(54) MANAGEMENT DEVICE OF THE EXECUTIVE BODY

WAY TO MMA

The invention relates to devices for the construction and repair of railway tracks and is intended for use in the automatic control system of executive workers of track machines during the process of straightening the glands of the new track road in the transverse plane.

A device for controlling an executive organ of a traveling machine is known, comprising a trolley mounted on it a distance sensor, including a measuring wheel, and a slope sensor mounted on a platform pivotally mounted on the trolley and connected to the executive organ 1.

The device does not provide an exact assignment of the elevation of the rail yarn for all possible transition curves, since it is intended to specify only a few values of the elevations of the driven rail yarn (for example: 0.67 / 1000.1 / 1000, 2/1000) with respect to the leading one. At the same time, during the construction of the railway, it is possible to change the values of the elevation elimination within

up to 3/1000.

It is also known that the control unit of the executive body is traveling

machine, containing a trolley, a carriage hinged on the trolley, a track inclination sensor mounted on the carriage and connected to the executive body, and a measuring wheel mounted on the trolley and connected to the carriage through the drive of its installation 2J.

The disadvantages of this device are associated with the absence of a rigid kinematic connection between the measuring wheel and the carriage movement drive in the vertical plane for setting the output of the driven rail thread over the lead in the function of the distance traveled, which can lead to the appearance and accumulation of errors and distortion of the position of the rail threads in transverse

20 plane, as well as with the presence of loss of working time for the calculation of calculations to determine the position of the carriage, depending on the length of the transition curve, the magnitude of

25 rail yarn at the end of the transition curve and elevation gradient gradient.

These drawbacks reduce the effectiveness of the device.

The purpose of the invention is to increase the efficiency of the device by increasing the accuracy of the installation of the executive body. To achieve this goal, the control unit for the traveling machine’s executive organ, containing those a bed, a carriage hinged on the trolley, a track inclination sensor mounted on the carriage and connected to the executive body, a measuring wheel mounted on the carriage and connected to the carriage through the drive its installation is equipped with an overtaking clutch mounted on the measuring wheel with a cam and regulated with a roller that interacts with the cam and connected to one coupling half of the overtaking clutch through a hinged pin. a lever, and another half-coupling is connected with a carriage installation drive. FIG. 1 schematically shows the control unit of the executive body of the traveling machine; in fig. 2 - section A-A in FIG. 1 .. The control unit of the executive body of the traveling machine comprises a measuring carriage 1 with a frame 2 on which a measuring wheel 3 attached to the cam 4 is fixed. On the frame 2 of the measuring carriage 1 the carriage 5 is hingedly mounted mounted on it sensor 6 slope path. With the cam 4, there interacts a pusher 7 that is adjustable in length, consisting of a micrometric screw 8 with an agile 9, and a stand for 10 s. roller 11, shtselsel 12, moving in the guides 13. Between the fixed cover 14 and the flange 15 of the shtselsel 12 an elastic element 16 is installed, providing the movement of the pusher down and pressing the roller 11 "to the cam 4. One coupling half 17 of the overtaking clutch 18 using the swing lever 19 pivotally connected to the length-adjustable push rod 7. The other coupling half 20 of the overtaking coupling 18 is fixed to the shaft 21, which through the gearbox 22 and the screw 23 with the nut 24 is connected to the carriage 5. The screw 23 with the nut 24 is the drive for mounting the carriage. The signal from the inclination sensor b of the path through the electronic amplifying unit 25 and the hydraulic distributors 26 and 27 control the movement of the actuator 28 by changing the position of the rail-sleeper grid 29. By specifying the position of the carriage 5, both of them prepare the required elevation of the path in the transient curves, and the specified gradient of elimination is provided by a stepless change the length of the pusher 7 by adjusting the micrometer screw 8. The change in the length of the pusher 7 is accompanied by a change in the value of its vertical movement in Performan reacting with the cam roller 11 of the carriage 4. Izmenenienapravleni skew placement 5 provided on the shaft sleeve with different passing direction of its working stroke position of the coupling halves and the change of the swinging lever 19 from the normal position, as shown in FIG. 1, to the position shown by the dotted line in the same figure. During the movement of the measuring carriage 1 together with the track machine, the cam 4 is continuously rotated together with the measuring wheel 3. The rotating cam 4, interacting with the roller 11, causes the push rod 7 coBepuiaTb reciprocating movements, the magnitude of which depends on the initial incrometric installation gradient screw depending on the given gradient of the height of the elevations in the transition curves. The movements of the pusher 7 through the swing arm 19, the half couplings 17 and 20 of the overtaking clutch 18 cause the shaft 21 to rotate, the latter rotating only in one direction, clockwise or counterclockwise, over the entire length of the transition curve. The movement of the shaft 21 through the gearbox 22 and the screw 23 with the nut 24 causes the carriage 5 to rotate around the hinge placed on the frame 2 of the carriage 1. B. As a result of the rotation of the carriage 5, an error signal appears at the output of the sensor b and by means of the amplifying electronic unit 25 through hydraulic distributors 26 and 27, an appropriate command is given to move the actuator 28 up or down depending on the mismatch sign. The actuator 28 moves the rail-fins lattice 29 on which the measuring carriage 1 is located, creating a path skew in the transverse plane equal to the specified angle of rotation of the carriage 5 relative to the frame 2 of the measuring carriage 1, but opposite in direction. In this case, the signal at the output of sensor b disappears and the movement of the track rail sleeper 29 is stopped. Thus, the device provides the setting of the position of the actuator 28 of the track machine with any amount of elevation retraction, for example, in the range of ± 3/1000 as a function of the path length, due to the stepless adjustment of the length of the pusher 7 using a micrometer screw 8, which improves the accuracy of the actuator and therefore, the effectiveness of the device. In the proposed device, a kinematic
