The inventive device for controlling and measuring the relative position of the holes butt-joint rail and their relative position to its end includes a rod 1 with hard sponge 2 for contact with the end face of the rail 3. The rod 1 is passed through the guides posted in the body of the control tubes 6. On the rod 1 marked measuring scale 7 and the scale of check marks 8. In the control tubes 6 are open 9 vizier 10 arranged on the corresponding scales of the rod 1. 1 C.p. f-crystals, 5 Il. The invention relates to railway transport, in particular to measurement and control used in the construction and operation of rail ways, specifically to a device for controlling and measuring the relative position of the holes butt connection of rails and their relative position to the end of the rail.The known device for controlling and measuring the relative position of the holes butt connection of rails and their relative position to the end of the rail containing the bar with hard sponge-coloured.In devices of this type on the rod is fixed at a fixed distance control tube for each of the holes in the rail that allows you to monitor the location of all holes. However, the tube in the known device is rigidly fastened to the bar, which complicates the use of the device, as it is practically impossible to quickly provide simultaneous contact of the measuring surfaces of the tubes in all holes and hard sponge with the ends of the rail, also not is determined by the true position of the center of the hole.The present invention is to avoid the above difficulties and to create a scheme of the device when the relative simplicity of the design would be a quick job to contact all measuring surfaces of the device with the object being measured and, in addition, would give the device a number of additional useful properties, namely the ability to renounce the use of cylindrical measuring tube surface and execute it, for example, conical, which in turn will not only facilitate the use of the device, but will also improve the reliability of the measurements, since the conical tube defines the true position of the axis resp.This is due to the fact that the device for measurement of the relative position of the holes butt connection of rails and their relative position to the end of the rail containing the bar with hard sponge for contact with the end face of the rail and set it in the control tube to communicate with the holes in the neck rail, tube made with placed within the body of the guide, through which omitted the rod, the rod is caused to the measuring scale and the scale ticks, and tubes made Windows with sight on opposite sides above the relevant scales rod.In this scenario execution device, the measuring surface of the control tubes can be performed, for example, conical, thereby increasing the accuracy of measurement, as determined by the real position of the axis of the hole.In Fig. 1 shows a device, a General view of Fig. 2 General view of the device in plan; Fig. 3 a view of the arrow in Fig. 1; Fig. 4 section b-B in Fig. 1; Fig. 5 the layout of the holes in the rail according to GOST 16210-77 and GOST 7174-75.The device consists of a rod 1 is rigidly fixed thereto resistant sponge 2, intended for contact with the curves) and 5 (spring), placed in the body of the control tubes 6.On the rod 1 applied: measuring scale 7 and the scale of check marks 8 hole location and tolerances for each type of rail (for example, P 50, P 65, P 75).In the control tubes 6 are open 9 vizier 10, which may be, for example, in the form of strokes drawn on the chamfers 11 Windows, each of sight is above the scale bar.Measuring surface 12 of the control tubes 6 are tapered, allowing the tubes to capture the true position of the center of the holes drilled in the rail. Measuring the surface of the tubes can be made in the form of a sphere, which will also allow you to capture the true position of the center holes in the rail (not shown).It is reasonable to provide a control tube retaining screws 13, which interacts with a spring guide 5, would provide the opportunity, if necessary still to secure the rod 1 relative to the tubes 6.Working with the device is as follows.Pre-control tube 6 are mounted on the measuring or control scales 7, 8 for the appropriate type Rastogi as a measuring rod will be pressed against the end face of the rail, the measurements are made by exact count on the scale of the device. 1. DEVICE FOR CONTROLLING AND MEASURING the relative position of the HOLES BUTT-joint RAIL AND THEIR RELATIVE position to ITS END containing the rod is rigidly fixed at one of its ends thrust sponge for contact with the end surface of the rail and mounted on the rod along the control tube to enter in the butt hole in the neck rail, wherein each of the control tube is made with located in the body of the guide, through which skipped the bar, and with a window opening onto the upper surface of the tube, with the upper surface of the rod caused the measuring scale and the scale ticks, and on opposite sides of the open tube on the corresponding scales of the rod caused the vizier.2. The device under item 1, characterized in that an input in the butt hole in the neck rail side surfaces of the control tubes is made conical.

SUBSTANCE: proposed multipurpose gauge contains rod, fixed and movable stops, handle with tie-rod guide, device for determining railway track gauge with scale and device for determining distance between working faces of core and guard rail and distance between working faces of check rail and guard rail furnished with scales, respectively, carriage for checking ordinates of transition curves, width of troughs and side wear of rail head furnished with end piece with scale and mating with scale on tie-rod. Proposed method of checking comes to the following: check measurement of gauge is carried out by means of carriage whose end piece is fixed relative to CHECK position notch made on end piece. Then carriage is shifted to side of movable stop until end piece comes in contact with side working face of rail head and readings are taken from carriage scale relative to GAUGE CHECK position notch found on rod. Then gauge is measured by known method. Difference between readings obtained by known method and check measurement should not exceed gauge measurement error. Correspondence of readings is determine by comparing track gauge measurements and measurements of distance between core and guard rail or measurement of distance between check rail and guard rail. Difference between any values of gauge readings and distance between working faces of core and guard rail or distance between working faces of check rail and guard rail should be fixed.

SUBSTANCE: system of installation of a previous element, then the subsequent element into a base comprises a setting stand with a displacement direction, at least one measuring post installed at the first sign for topographic survey and a unit for direction of the setting stand movements. The method of installation of a previous element, then the subsequent element into the base consists in the fact that at first nominal positions are identified, in which the elements are to be installed into the base, depending on a theoretical trajectory. Then absolute error is determined in position of the previous element relative to the nominal position, into which the previous element is to be installed. Afterwards the setting stand is automatically sent to the assigned position, in which the subsequent element is to be installed, depending on absolute error of positioning determined for the previous element, to reduce the relative error of the subsequent element positioning relative to the previous element.
EFFECT: reduced relative error of installed elements positioning.
