In Fig. 1 shows a track machine with a device for mounting a tool frame on rails; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 2; Fig. 4 and 5 embodiments of the device for installation of the tool frame on the rails.

Mobile travel machine (Fig. 1) has a bridge-type frame 1 installed via rail undercarriage 2 on the railroad 3. On the frame 1 are to conduct repairs two height-adjustable transversely of the machine spelaeogriphacea unit 4, one paleothermal and straightening unit 5 containing the actuators lifting and straightening, as well as managing these units reference system 6 leveling and straightening. The Central power unit 7 is used to drive all located on the machine actuators. To determine the actual position of the train path 3 is provided for rolling on the path of the measuring carriage 8 is connected between widely spaced apart rail-road trucks 2 through actuators with adjustable height and breadth of the machine frame 1 and for centering when installing on the road equipped with a device 9 for installation is shown in Fig. 2 and 3, the device 9 to install the tool frame on the railway consists of two (in their lower position reading) located above the rails and mirror relative to each other parts, of which for simplicity shows only the part situated above the left rail. This part of the device 9 has a carrier frame 11 fixedly connected with the tool frame 12 of the measuring trolley 8. Instrumental frame 12 by means of the actuators 13 and 14 move in height across device pivotally attached to the frame 1 of the machine is adjustable in relation to it and has wheels 15 with the flange provided for contact with the rails 16 of the path 3. Perpendicular to the longitudinal direction of the machine of the rotary plate 17 formed through two levers 18 parallelogram hinge connection pivotally attached to the base frame 11 and is adjustable relative thereto by means located on the support frame 11 and is designed as a spring-loaded power cylinder rotary actuator 19 in the transverse plane running perpendicularly relative to the plane of the path and in the transverse direction of the machine (see indicated in phantom lines upturned position on the lion the Ooty rotary plate 17 to limit its rotary movement still attached to the vertical fence 20 of the supporting frame 11.

The lower passing is basically parallel to the plane of the path and the axis 21 of the wheel 15 with the flange end zone of the rotary plate 17 is made in the form of contact strips 22, consisting of two spaced stepped offset relative to each other along the height of sections 23 and located below the section 23 has a vertical stop 24 for contact with the side surface of the head 25 of the rail 16. The length of the sections 23 of the strap 22 is the result of a boom lift arc of the circle described by rail with a minimum arc radius, depending on the length of a chord of the circle formed by the spaced apart rail-road trucks 2. To fit to the head 25 of the rail 16 of the contact strip 22 has a bearing surface 26 of insulating material 27. Central in relation to both perpendicular to the longitudinal direction of the machine parts of the strap 22 is flat body 28 made as well as covered with insulating material 27 rocker slats 29, resulting in its upper end position limit switch 30. Last through the wire 31 is connected with the hydraulic valves 32 and 33 to control the loading prepackage and/or acoustic signal.

Before installing on the path of the measuring carriage 8 is removed from the path 3, respectively, raised non-working position. When loading the respective rotary actuator 19 is first rotated to its lower end position, the position of the reading, the rotary plate 17 until then, until it is adjacent to the stop 20. In this position, located on the contact strip 22 of the indicator body 28 is located under the wheel 15 with the flange in its perpendicular axis 21 radial plane 35. After the instrumental frame 12 via the actuator 13 is lowered until then, until the contact strip 22 is not flat against the head 25 of the rail 16. When following the loading of the actuators 14 is cross movement, and accordingly the movement of the reading position of the tool frame 12 and connected to the devices 9, respectively, of the contact strips 22 in the transverse direction of the machine. As soon as the head 25 of the rail 16 comes to contact with the stop 24, the wheel 15 is in the desired position on the rail 16, the radial plane 35 is approximately identical with the plane of symmetry of the rail. Due to the head 25 of the rail 16 at the same time is driven by a reversible bar 29, which its ignitee movement of valve 32 to the zero position, what locks the actuator 14 and ends the movement of the reading position. At the same time the operator due to the optical and/or acoustic signal shows the correct position of the wheels 15 on the rails 16.

Once when loading the rotary actuator 19 of the rotary plate 17 together with the contact plate 22 is again up in its off state, due to the actuators 13 move in height may be the final lowering of the tool frame 12, respectively, of the measuring bogie 8, into position to fit the wheels 15 to the rails 16. The valve 32 under the influence of the return spring moves to the flow of the fluid, so that the actuator 14 in the framework of the working machine can be used freely for lateral retraction of the measuring bogie 8 on one of the both rails.

In Fig. 4 shows the following embodiment of the invention. Travel machine 36 has a frame 37, which is pivotally attached for movement in height across the machine through the actuators 38 and 39 instrumental frame 40. This frame is equipped with working tools (not shown) such as lifting rollers for lifting and reels along the path 43. The beam 42 is arranged with a distance from each other on the gauge indicator bodies 44. Both of the end section 45 of the beam 42 are offset, as shown by the left arrow in height relative to the located between the indicator bodies 44 of the Central part and at the expense of this form lugs 46, stepped form provided to fit to the head of the rail 47. The length of the end sections 45 corresponds to the greatest desired lateral deviation of the instrumental frame 40 from the centre of the machine to rounding ways depending on the distance between the undercarriage bogies machine 36. Instrumental frame 40 has a wheel 48 with a flange, which is mounted for movement along the height of the tool frame 40 in the respective vertical guides at the expense of own adjustment actuator 49. In their upper end position of the wheel 48 with the flange are located above the contact strip 41 of the indicator bodies 44 and above the supporting surface of the contact strips 41.

The installation process on the path, respectively, the process of centering, begins with the lowering of the tool frame 40 with a drive 38 to until the contact strip 41 will not fit to both nd the instrumental record frame 40 in the transverse direction of the machine, which ends with fixing rails 47 on the lugs 46 and/or the actuation of the indicator bodies 44 through outbound from them a trip signal to the actuator 39. Wheel 48 with the flange are now just tsentrirovannoi above the rails 47 and fall due to the loading of the adjusting drives 49 until such time as they will be in contact with the rails 47. Through following this further loading of the adjusting actuators 49 and control with pressure relief actuators 38 height adjustment is the push-up tool frame 40 and located on it contact strips 41 of the track 43, making contact strip 41 is removed from contact with the rail means. Instrumental frame 40 is now free to roll along the path 43. Naturally is also possible that the indicator body of the mounting device on the path gave out only acoustic and/or optical signal, prompting the operator to immediately finish passing in the transverse direction of the machine the movement of the reading position.

Indicator body 50, which can be seen in Fig. 5, is an inductive relay for contactless please take the 15 with the flange. The installation process on the railway is entered by turning down the swing frame in a position reading. After lowering device 9 to install on the path together with the connected with it instrumental frame and fit contact strips 22 to both rails 16 path is transverse moving the whole site up until the indicator body 50 in it just above the rail 16 position does not trigger lock actuator transverse adjustment and/or acoustic or optical signal.
