Description

The invention relates to the mechanization of works on the assembly of turnouts in track facilities of railway transport and can be used in a line for the assembly of turnouts with reinforced concrete beams on a specialized basis.

There is a well-known stand for assembling turnouts (the magazine “Way and track economy”, 2005, No. 8), where the bars are laid out by a crane using a template ruler with the marks of the axis of the beam. A disadvantage of the known stand is that the guidance of one end of the beam to align it with the mark of the ruler is done manually, while there remains uncertainty about the position of the second end of the beam and the size along the ordinate. A device for marking the position of the bars on the assembled railroad switch (RF patent No. 2131109. Turovsky tape measure for marking the position of the bars on the railroad switch, 03/13/1996), the disadvantage of which is that the marking of the position of the beam is done manually. It is known "Device for assembling rail-sleeper lattice of the railway track", and.with. No. 1120050 and “Stand for the assembly of turnouts”, RF patent No. 2007507. The disadvantages of the known devices are: firstly, the use of manual labor when installing each timber in place, and secondly, the use of a template in both devices allows the assembly of only one mark of the turnout switch, and in case of change (right translation, left or cross translation , brands 1/9, 1/11 and others) it is necessary to rebuild the template, which requires additional time and which limits the technological capabilities of known devices. A device for laying out sleepers (Yu.A. Orlov and A.V. Yeghiazaryan. Production bases of track machine stations. Fundamentals of designing mechanization tools. - M .: Transport, 1986, p. 53-54, Fig. 2.8 - adopted as a prototype ), which consists of a portal frame that moves along the rails of the enclosing path of the stand on wheels, and a bearing beam with a lifting mechanism equipped with legs for lifting the sleepers and moving them to a certain distance. The required distance can be counted by various known means, including using an enclosing path laid along the rail of the measuring chain, along which the sprocket rolls, the rotation angle of which produces a stop signal in accordance with the program of the command device.

A disadvantage of the known device is that it cannot be used for the layout of the bars of the turnout switch, since it is impossible to layout the bars so that their rotation angles with respect to the axis and ordinate are observed, in addition, it is impossible to work with the bars of different lengths.

The objective and purpose of the invention is to provide a mobile device for moving reinforced concrete beams of turnouts of different lengths and stacking them exactly according to the diagram with the necessary angle of rotation of individual beams and observing the ordinate. At the same time, it should be possible to assemble turnouts of different brands and different directions.

The task is achieved in that in a mobile device for installing reinforced concrete beams of turnout according to the diagram and ordinates, containing a portal frame that moves along the guides of the enclosing path of the stand on wheels, and carrying a beam with a mechanism for lifting the beam, equipped with paws for lifting the beam and its movement, the portal the frame is made in the form of two trolleys that are moved along the guides of the enclosing path of the stand on wheels independently of one another, one on the right and the second on the left side of the track, with power cylinders and a joint interconnected by articulated rods, each trolley equipped with a command device with a set of movement programs, each of which is kinematically connected via an asterisk to segments of measuring chains laid along the guides of the enclosing path of the stand, and a slider is placed on each trolley with the possibility of longitudinal movement, each of which pivotally connected to each other by a guide for two carriages having the ability to move relative to each other by means of a lead screw, the drive of which is placed on their guide and each carriage is equipped with a drive nut corresponding to the lead screw, in addition, each carriage is equipped with a pair of rollers for orienting the beam along its longitudinal axis and a beam lifting mechanism, on each foot of which there are two movable, spring-balanced in the longitudinal and transverse directions of the thrust bearing, at the same time, a scanning device is installed on one of the sliders, which is equipped with the device, for searching the holes of the embedded bolt in the beam, in addition, each trolley and its power hydraulic cylinders are equipped with clamps for releasing sy.

Each cart of the portal frame contains four wheels, and each guide of the enclosing path of the stand on the right and left sides of the path contains two parallel rails.

The implementation of the portal frame in the form of two trolleys that are moved along the guides of the enclosing path of the stand on wheels independently of one another, one on the right and the second on the left side of the track, with power cylinders and interconnected by articulated rods, supplying each trolley with a command device with a set of movement programs, each of which is kinematically connected through an asterisk with segments of measuring chains laid along the guides of the enclosing path of the stand, placement on each trolley with the possibility of longitudinal movement of the slider, each the second of which is pivotally connected to each other by a guide for two carriages that can be moved relative to each other by a lead screw, the drive of which is placed on their guide, supply each carriage with a lead screw with a drive nut, supply each carriage with a pair of rollers to orient the beam along its the longitudinal axis and the beam lifting mechanism, on each paw of which are two movable, spring-balanced in the longitudinal and transverse directions of the thrust bearing, supply device using a scanning device to search for bolt holes in a bar mounted on one of the sliders, supplying each trolley and their power cylinders with clamps behind the rails allows you to provide accurate dimensions for obtaining plots of reinforced concrete railings of railroad switches of different lengths with the required angle of rotation of individual bars to the axis of the track and compliance ordinates. At the same time, it is possible to assemble turnouts of different brands and turnouts of different directions by changing the programs of the command devices.

The implementation of each cart portal frame four-wheeled, and each guide enclosing path of the stand with two parallel rails allows you to provide a more reliable position of the portal frame and the entire device during operation.

In addition, the proposed mobile device can be used in the assembly of turnouts with wooden beams provided that the scanner is configured for the end of the beam (receiving a hole line).

A mobile device for installing reinforced concrete switchgear according to the diagram and ordinates contains a left trolley 1 and a right trolley 2, each of which moves along the rail of the guide 3 of the enclosing path of the stand on two wheels 4 independently of one another, one on the right and the second on the left side ways, power hydraulic cylinders 5 (figure 3). Carts 1 and 2 are interconnected by two articulated rods 6, forming a portal frame. A slider 7 is placed on the left trolley 1, and a slider 8 is placed on the right trolley 2 with the possibility of longitudinal movement from the power cylinders 9 and 10, respectively. The sliders 7, 8 are pivotally connected to each other by a guide 11 for two carriages 12 and 13, which can be moved relative to each other by a lead screw 14, the drive 15 of which is mounted on the guide 11. The carriages 12 and 13 are equipped with nuts 16 and 17 corresponding to the lead screw 14 Each nut 16 and 17 has its own drive 18. A pair of rollers 19 are mounted on the carriage 12, and a pair of rollers 20 (Fig. 3) is mounted on the carriage 13 to orient the beam 21 along its longitudinal axis. On the carriages 12 and 13, the mechanisms for raising the beam 22 and 23, respectively, are also mounted. For free rotation of the beam 21 when it is mounted on the axis on each paw 24 of the lifting mechanisms 22, 23, two movable thrust bearings 25 are placed, spring-balanced in the longitudinal and transverse directions by springs 26 and 27, which are displaced together with the contact point of the thrust bearing 25 with the bar 21 (Fig.6, 7). In order to exclude the return turn when lowering the beam 21, i.e. when the beam loses contact with the rollers 19, 20, the position of the thrust bearings 25 changes with a decrease in their height in space, so the springs, calculated only on the force of returning the thrust bearings, will not be able to raise the beam. On the guide 11, from the side of the slider 7, a scanning device 28 is installed (Fig. 4) for searching the holes 29 of the embedded bolt in the timber 21 (Fig. 7) to obtain a hole line. Each truck 1 and 2 is equipped with clamps 30, and their power hydraulic cylinders 5 are equipped with clamps 31 for the rails of the enclosing path of the stand. Independent from each other, the movement of the left 1 and right 2 bogies pivotally connected by rods 6 is provided by command devices 32 with a set of movement programs, each of which is kinematically connected via sprockets 33 with segments of measuring chains 34 laid along the rails of the guides 3 of the enclosing path of the stand with the right and on the left side of the path. Each slider 7 and 8 is associated with limit switches 35 and 36, respectively. A variant of the execution of trolleys 1 and 2 with four wheels 4 is provided, and then the guides 3 of the enclosing path of the stand on the right and left sides of the path contain two parallel rails for moving four-wheeled left 1 and right 2 trolleys along them (Fig. 5).

The operation of the device for installing reinforced concrete beams of turnout according to the diagram and ordinates is as follows.

In the area of the location of the enclosing paths with guides 3, a vehicle is supplied with bars 21 previously laid out by the crane, and the deviation of the laid beam from the theoretically required one is within the contour created by the bogies 1,2 and rods 6. The left 1 and right 2 bogies are moved by hydraulic cylinders 5, the grippers 31 fixed to the rails of the enclosing paths, each at its own precisely oriented distance defined by the programs of the command devices 32 and read from the angle of rotation of the sprockets 33 when they interact with ezkami dimensional chains 34, stacked along the guide rails 3 of the ambient stand path. After stopping the bogies 1 and 2 are fixed to the rails by grippers 30, and the grippers 31 are opened and pulled by the rods of the hydraulic cylinders 5 to the end of the stroke of the rods and are again fixed on the rails. After the bogies 1 and 2 have stopped, the sliders 7 and 8 are shifted by the power hydraulic cylinders 9 and 10 in the direction of the previously laid beam 21, and the carriages 12 and 13, at this time, are moved apart by the nuts 16, 17 from the drives 18 and the lead screw 14 from the drive 15. Paws 24 of the mechanisms for raising the beam 22 and 23 in the initial position are located below the lower bed of the beam 21. When the limit switches 35 and 36 contact the beam 21, the sliders 7 and 8 stop, and the carriages 12 and 13 are shifted to the beam 21. The lifting mechanisms 22 and 23 are turned on , the beam 21 is picked up by the paws 24, rises and sets row rollers 19 on one side and roller 20 on the other hand, also located on the carriages 12 and 13, whereby the timber axis is centered on the axis of the carriages. Since the stop by the end switches 35 and 36 is approximate, when the bar 21 is inserted between the pairs of rollers 19 and 20, it turns around a little, which in the paws 24 is compensated by the springs 26, 27, which are spring-loaded in the longitudinal and transverse directions, by the thrust bearings 25. After the beam is fixed 21 in the rollers 19 and 20, the sliders 7 and 8 are returned by the hydraulic cylinders 9 and 10 to their original position, thereby setting the beam 21 along the desired theoretical axis. Then, the drive 15 of the lead screw 14 is turned on, and the carriages 12, 13 together with the beam 21 are displaced along this axis until the hole 29 under the embedded bolt of the beam 21 falls into the range of the scanner 28, and the rotation of the screw 14 is stopped. Thus, the beam 21 is brought to a predetermined position. At this position, the beam 21 is preferably provided with gaskets, linings, assemblies of embedded bolts, since it is raised and these operations are conveniently performed, after which the beam 21 is lowered to the base, the legs 24 are pulled out from under the beam 21, and the trolleys 1 and 2 of the device are moved for processing the next bar.
