Description

The invention relates to the mechanization of assembly and renovation (disassembly, replacement of defective elements and assembly) of rail links in a bench way (the links are laid out on a stand, the actuators move along an enclosing path above the stationary materials) at the production base of the track machine station.

The famous "Layout of sleepers on the diagram", and.with. No. 958568, ЕВВ 29/13, in which on the device moving along the sweeping path on two longitudinal beams on flexible suspensions spaced by a step of the plot, fixed elements are inserted into the holes for the embedded bolts of the sleepers. After raising the beams, the sleepers hang in the air, set according to the diagram, after which they fall on the rails of the bench path. The main disadvantage of this device is that it is required to manually insert and pull out two embedded elements into each sleeper, that is, a large amount of manual work. In addition, sleepers must be pre-laid out in four pieces in a row at a certain distance between these rows. It is also extremely difficult and time-consuming to reconfigure the device to another sleepers diagram.

It is known “Device for overloading and leveling the sleepers”, ЕВВ 29/06, B65G 47/54, when using which the sleepers are fed to the device in a continuous flow, with the help of a reciprocating traverse, are placed on a step-by-step conveyor (rail) fixed on it is located on the plot stops. Then, after the sleepers are removed from it, the rail returns and a new set of sleepers occurs. This device is applicable in production lines with moving link materials and cannot be used with the bench assembly method, that is, with stationary materials and actuators moving along them.

Known "Device for laying sleepers on the diagram on the link assembly line", and.with. No. 746017, ЕВВ 37/00, and "A device for laying out sleepers on a plot on a link assembly line", US Pat. 1789581, ЕВВ 29/10, 37/00. Known devices also cannot be used with the bench assembly method. It should be noted that in all the listed devices the installation of sleepers on the "cord" does not occur, that is, their alignment relative to the axis of the path.

A mobile device for laying out sleepers according to the diagram is known (Link assembly and linking complexes of industrial bases of the PMS: Textbook for universities of railway transport. / Under the editorship of S.G. Shtarev. - M .: Route, 2006. - p. 53- 54, Fig.2.7b, taken as a prototype), the basis of which is a spatial portal frame, based on wheel bearings moving from the drive along the rails of the enclosing path. The frame is mounted pivoting, thrust levers, pushers, a measuring roller in contact with the rail, connected with a shaped cam that controls, by means of a limit switch, the rotation of the thrust levers-pushers. When approaching the sleepers, the thrust levers-pushers are located in such a way that they are in contact with the lateral surface of the sleepers. After a full rotation of the measuring roller, which corresponds to the size of the sleeper plot, the pusher levers turn, contact with the tie is lost and the device, driving over the installed tie, comes into contact with the next tie by the persistent levers-pushers. The disadvantages of this device include errors in obtaining a diagram of sleepers due to slipping of the measuring roller, as well as the fact that the sleeper remains in the initial, transverse position (as it was laid) relative to the axis of the path, that is, the "cord" line is not maintained. In addition, when shifting several sleepers at once, depending on their number, the coupling weight of the device is not always enough, its slipping is observed. This is especially true in the case of repair of rail links, when it is necessary to return the sleepers in order to obtain a plot.

The objective and purpose of the invention is the creation of a mobile device for installing sleepers on the plot and the "cord" when assembling or renovating rail links at the industrial base of the ICP.

The objective is achieved by the fact that a mobile device for installing reinforced concrete sleepers according to the diagram and "cord" when assembling and renovating rail links on the bench path, made in the form of a frame resting on wheel supports to move along the enclosing path of the bench, on which rotary, thrust levers are mounted with the possibility of interacting with the tie and associated with the control unit is equipped with a mechanism for installing the ties on the "cord", made in the form of a beam mounted on a frame movable in a vertical plane from the hydraulic cylinder, carrying two sliders placed in the guides, in the lower part of each of which a pivot lever is pivotally mounted with the possibility of interacting with the flange of the sleeper recess under the lining, and a step-by-step mechanism consisting of two hydraulic cylinders mounted on the device frame, the rod of each of which is pivotally connected to the movable a carriage equipped with clamping grips for fastening to the rails, while the aforementioned traverse is mounted on the frame at a distance from the rotary, persistent levers, a multiple of the step of the plot. The command device of the mobile device is kinematically connected with an asterisk pivotally mounted on the frame with the possibility of rolling around in a dimensional chain laid along the rail of the enclosing path of the stand.

Introduction to the device of the mechanism for installing sleepers along the "cord", made in the form of a beam mounted on a frame movable in a vertical plane from the hydraulic cylinder, carrying two sliders placed in the guides, in the lower part of each of which a pivot arm is pivotally mounted with the possibility of interacting with the flange of the sleeper recess under the lining and placement of the traverse on the frame at a distance from the rotary, persistent levers, a multiple of the step of the plot, allows you to set the sleepers relative to the axis of the path, that is, withstand the "cord" line at Novki sleepers on the diagram. The introduction of a step-by-step movement mechanism, consisting of two hydraulic cylinders mounted on the device frame, the rod of each of which is pivotally connected to a movable carriage equipped with clamping grips for fastening to the rails, provides, for example, during the renovation of links, given that the sleepers diagram on old links knocked down and when it is necessary to return the sleepers in order to be able to obtain a plot, to make a shift of several sleepers at once during the reverse stroke of the device without slipping. To eliminate the error in obtaining the sleepers diagram, possible as a result of slipping of the measuring roller, the drive of the command device with a displacement size counter is made in the form of an asterisk rolling around on the measuring chain laid along the rail of the enclosing path of the stand (pin engagement).

A mobile device for installing reinforced concrete sleepers along the diagram and the "cord" contains a portal frame 1, supported by two running 2 and two driving 3 from the drive 4 wheel supports for moving along the rails 5 of the path of the assembly stand 6. In the middle part of the portal frame 1 mounted rotary , stop levers 7 for interacting with sleepers 8. At the free end of the frame, at a distance from the rotary, stop levers 7, which is a multiple of the step of the sleepers diagram, there is a mechanism for installing sleepers along the "cord" 9. A step movement mechanism 10, pa displaced between the running 2 and driving 3 wheel supports, and an asterisk 11 is pivotally mounted with the possibility of rolling along a measuring chain 12 laid along the rail 5 of the enclosing path, and kinematically connected with a command device that carries a counter for the size of movement of the sprocket (not shown), which, in turn, it is connected with pivoting, persistent levers 7. The mechanism for installing sleepers along the “cord” 9 comprises a crosshead 13 with a hydraulic cylinder 14 carrying two sliders 15 placed in the guides 16, which are installed in the arch 17 of the portal frame 1. On the lower end of each slider 15 is secured by a pivoting lever 18 with stops 19 and 20 arranged so that each lever 18 is able to interact with the flange of the sleeper recess 21 under the lining. The step-by-step movement mechanism 10 consists of two hydraulic cylinders 22, each of which is fixed on the frame 1, and its rod 23 is pivotally connected to the movable carriage 24 with clamping grippers 25 for fastening to the rails 5 of the ambient path.

The operation of a mobile device for installing reinforced concrete sleepers on the diagram and the "cord" is as follows.

On bench stand 6, a row of sleepers 8 of 4 or 8 pieces is laid out by a crane or a trellis raiser, one adjacent to each other and somewhat offset from the required position to the side opposite to the direction of movement of the device, if work is required to renovate the link. When approaching the first sleepers 8 rotary, thrust levers 7 are installed in the working position. The stop levers 7 abut the sleeper 8, shifting the entire row of sleepers, and the device moves to a distance specified by the command device, the counter of which is driven from the sprocket 11, rolling along the measuring chain 12. The command device sends a command to stop the device and raise the rotary, stop levers 7 The levers 7 are rotated, the device passes over the sleepers 8 and the levers 7 are lowered behind the sleepers into the gap between the sleepers and move the sleepers to a distance specified by the control unit. Next, the installation of sleepers on the plot is repeated. When the device passes a distance equal to the distance by which the mechanism for installing sleepers along the "cord" 9 from the rotary, thrust levers 7, the levers 18 will occupy a position above the sleeper recess 21 (Fig. 3, position a) and the mechanism for installing the sleepers along the "cord" 9 will begin the installation of sleepers 8 along the axis of the bench path. The traverse 13 hydraulic cylinder 14 is lowered, the sliders 15, moving in the guides 16, lower the levers 18 into the sleeper recess 21 (figure 3, position b). The levers 18 are in contact with the surface of the sleeper recess 21 and, sliding along it, abut against the flange of the sleeper recess 21 and combine the axis of the sleeper 8 with the axis of the bench path. The alignment of the axis of the sleepers 8 with the axis of the path occurs at the moment when the levers 18 come into full contact with the stops 20 (Fig. 3, position c). After installing the sleepers along the axis of the path, the crosshead 13 rises together with the levers 18. The extreme lower positions of the levers 18 are determined by the limiters 19. In the same way, the rest of the sleepers 8 are set along the “cord” line.

During the renovation of the sleepers links on the old-time dismantled links, most often, the sleepers diagram on the old links is knocked down. Therefore, the device passes over several sleepers 8 with raised thrust levers 7, which are lowered from the back of the sleepers and, in the reverse direction of movement of the device, collect sleepers 8 in a row (Fig. 5). Then the device returns to the first sleepers in the row of assembled sleepers and the installation of sleepers on the diagram and "cord" is repeated. Given that when the sleepers are shifted, the resistance increases and the wheels of the device can slip, the step-by-step movement mechanism 10 is switched on. The clamps 25 of the carriage 24 are fastened to the rails 5 and, by means of the power cylinder 22, the device moves a predetermined distance. During the stop of the device for shifting the sleepers along the "cord" line by the reverse stroke of the rod 23 of the cylinder 22 of the carriage 24 are pulled to their original position.
