Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used in the assembly of the links of the rail-sleeper lattice, mainly by the bench method.

With the bench method of assembling the links, their assembly is carried out on the bench track (a regular section of the railway track), on which the elements of the rail-sleeper grid are laid out, and actuators are moved along the rail track enclosing the bench path.

A device for laying out sleepers on a diagram on a link assembly line (USSR Author's Certificate No. 1789581, IPC ЕВВ 29/10, 37/00 (2006.01). A device for laying out sleepers on a diagram on a link assembly line / B. G. Tonkonogov, V. I. Ilyinsky, A.I. Margolin, I.F. Skripachev; PKTB of the KhabIIZhT. - No. 4897140/11; decl. 12/27/1990; publ. 23.01.1993. Bull. No. 3. - 3 pp. 6 ill.). The device comprises a trough feeder and a portal frame in the form of a gantry unit (gantry carriage) mounted on wheels for moving along a rail enclosing an assembly bench path and equipped with controlled stops for interacting with side faces of reinforced concrete sleepers and sleepers position sensors spaced relative to each other in the direction of the sleepers moving a distance multiple of the step of the plot.

The device operates as follows. The layout of the sleepers is carried out with continuous or periodic movement of the portal cart.

The sleeper installed on the diagram moves beyond its lateral edge with the lowered supports mounted on the cart, while the second lateral edge it moves the next sleeper to be installed in the diagram, the movement of the sleepers is carried out when they slip along the longitudinal beams (rails) of the receiving means for sleepers. When the sleepers position sensors reach the sleepers previously set according to the diagram, they are instructed to raise the stops. The stops are lifted, the trolley continues to move, and the sleepers moved up to this point are from the previously installed diagram at a distance equal to the selected interval between the laid sleepers, since the position sensor of the installed sleepers is placed from the stops at a distance equal to or a multiple of this interval.

After the trolley passes with the stops raised, the distance equal to the width of the upper edge of the sleepers, the command to lower the stops is received from the sleepers position sensors. The stops are lowered, and the next sleepers installed on the diagram are moved until the sensors of the sleepers have just reached the sleepers established on the diagram, and a command is issued to raise the stops to leave the next sleepers installed on the sleepers on the longitudinal beams of the sleepers. Next, the cycle repeats.

The required sleepers diagram is set by the longitudinal displacement of the sleepers position sensors in one direction or another by the amount of the diagram change.

The advantage of the device is that it allows you to arrange the sleepers on the diagram in automatic mode, as the stops work according to the commands of the sensors. Adjustment to the required sleepers diagram is carried out by shifting the sensor by the amount of change in the sleepers diagram. Thus, the process of laying out sleepers on a plot can be automated by sequential submission of appropriate commands to the executive bodies.

The disadvantage of the device is that, despite the simplicity of the layout of the sleepers, it does not allow to lay them down when laying a number of 8 reinforced concrete sleepers, which is preliminarily made according to the marks on the stand path (eight sleepers in a row correspond to the incoming package of reinforced concrete sleepers). This is due to the insufficient coupling force of the wheels of the trolley with rails, which is complicated by oil pollutants. Therefore, the accuracy of stopping the trolley is not guaranteed due to the possible slippage of the wheels on the rails.

A device for installing reinforced concrete sleepers on the plot of the assembled link on the bench path (Patent No. 2376411 of the Russian Federation, IPC ЕВВ 29/13 (2006.01). A mobile device for installing reinforced concrete sleepers on the diagram and the "cord" / A.I. Margolin, V.E. Vasiliev, I.F. Skripachev, R.T. Bogomolova; Federal State Institution Scientific and Technical Center “Track Machines” of the Federal Agency for Railway Transport (RF). - 2008121491/11; claimed May 27, 2008; published on December 20, 2009. Bull. .- 10 p.: 6 ill.).

The device comprises a frame supported by wheel supports (a portal carriage) for moving along a rail enclosing an assembly bench path, pivoting, stop levers (stops) for interacting with side faces of reinforced concrete sleepers mounted on a portal carriage with the possibility of rotation and connected with a command apparatus, and sleepers position sensors, an asterisk kinematically connected to the control unit and pivotally mounted on the portal trolley with the possibility of rolling around on a measuring chain laid along the rail the path of the stand, the truck is equipped with a gantry associated by rams sliding table at the bottom of the gantry wagon and equipped grips for fastening rails for enclosing the way.

The device operates as follows.

On the bench path with a crane or a trellis raiser, rows of sleepers of 4 or 8 pieces are laid out close to each other. When approaching the first sleepers, rotary, thrust levers are set into working position. The persistent levers abut the sleeper, shifting the entire row of sleepers, and the device moves to a distance specified by the command apparatus, the counter of which is driven by a sprocket rolling on the measuring chain. The command device instructs to stop the device and raise the rotary, persistent levers. The levers turn, the device passes over the tie, and the levers fall behind the tie into the gap between the sleepers and move the tie to a distance specified by the control unit. Next, the installation of sleepers on the plot is repeated.

The advantage of the device is the ability to install sleepers on the plot when assembling the links. The device, in comparison with the analogue, allows you to move a number of reinforced concrete sleepers of 8 pieces when laying (eight sleepers in a row corresponds to an incoming package of reinforced concrete sleepers). This is due to the fact that the movable carriage is equipped with grippers for attaching the portal carriage to the rails of the enclosing path.

The disadvantage of this device is that the adjuster of the next step in the diagram of the sleepers of the link from the control unit, the size counter of which is kinematically connected with the sprocket being rolled around the measuring chain, is complex, its accuracy depends on the accuracy of the chain, its installation and the process of rolling the sprocket over it. The error of each next step of the diagram is summed up, which does not guarantee the necessary position on the diagram of the link of the first and last sleepers. In addition, the use of a movable carriage with grips behind the rails guarantees the displacement of a number of sleepers, but this disrupts the device’s operating cycle with a reset of the command device, which leads to the need for manual control. All this leads to a decrease in productivity and operational efficiency of the device.

The objective of the invention is to create a device for laying out sleepers on the plot when assembling the links of the railway track, which allows to increase the productivity and efficiency of the device when laying reinforced concrete sleepers on the plot on the bench path by gradually separating the sleepers from a number of sleepers and arranging them on the plot of the assembled link with reliable moving sleepers along the bench path to the step of the plot, with reliable fixation of each step of the plot, with zeroing the error of each step in the implementation of the next.

To solve the problem in the device for laying the sleepers along the diagram when assembling the links of the railway track, containing a gantry carriage moving along the enclosing bench assembly track, equipped with sleepers position sensors, controllable stops for interacting with the side faces of reinforced concrete sleepers and a movable carriage, a movable carriage mounted on a portal trolley with the possibility of moving along it along the guides, controlled stops made vertically rotatable to move them on the floor When the arc is placed between the lateral faces of adjacent sleepers and mounted on a movable carriage, the portal carriage is equipped with grips for the rails of the track stand envelope, and the carriage is equipped with a step adjuster for the sleepers diagram, while the carriage travel specified by the step adjuster for the sleepers diagram is carried out after zeroing of all previous commands by the position sensor command installed on the sleepers diagram of the sleepers link.

Signs that distinguish the claimed solution from the prototype are: the installation of a movable carriage on a portal carriage with the ability to move along it along the guides, the execution of controlled stops vertically rotated to move them in a gentle arc when placed between the side faces of adjacent sleepers and their location on a movable carriage, supplying the portal carriage with grips for the rails of the enclosing stand of the track, equipping the carriage with a step setter for the sleepers diagram, implementing the carriage movement after updating the removal of all previous commands by the position sensor command installed on the sleepers link diagram of the sleepers link.

The presence of significant distinguishing features in the aggregate of essential features characterizing the claimed solution, indicates its compliance with the patentability criterion of "novelty."

Thanks to the distinctive features, the efficiency of the device and its performance are increased. This is due to the fact that the installation of controlled stops for interacting with the lateral faces of reinforced concrete sleepers on a carriage along the guides along the portal carriage equipped with a step adjuster for the sleepers diagram, and the equipment of the portal carriage with grippers behind the rails of the path that surrounds the stand allow reliably moving any number of ties row of sleepers when cutting off the next sleepers from the row to install it on the step set by the specifier of the plot of the assembled link. The execution of controlled stops for interacting with the side faces of the sleepers vertically rotated to move them in a gentle arc allows you to reliably place them in the gap between the side faces of the adjacent sleepers of a number of sleepers, without shifting the sleeper installed on the diagram. Carrying out the movement of the carriage to the step of the link sleepers diagram after zeroing all the previous commands with the position sensor command from the sleepers installed on the link sleepers diagram ensures a stable step of the link sleepers diagram without running from step to step when laying out all sleepers along the diagram of the link sleepers set.

In FIG. 1 shows the proposed device, side view. In FIG. 2 is a view A in FIG. one.

The device comprises a portal carriage 1, equipped with running wheels 2, a drive 3 for moving along the enclosing bench path 4 with a number of sleepers 5 of the rail track 6, a movable carriage 7 mounted on the portal carriage 1 and moving along it along the guides 8 using the drive 9, connecting a mobile carriage 7 with a gantry carriage 1. The gantry carriage 1 is equipped with grippers 10 for the rails of the enclosing path 6 and a position sensor 11 installed on the sleepers diagram 5. The carriage 7 is equipped with vertically rotatable canopy second arc drive 12 stops 13 for interacting with the side faces of the sleepers 5 and the adjuster of the pitch of the diagram sleepers 14.

The device operates as follows.

The gantry truck 1 with the controlled stops 13 of the carriage 7 raised and the position of the latter in the initial (extreme right) position with open jaws 10 is moved by the drive 3 to the sleepers 5 laid on the diagram, the first or any intermediate, and by the command of the position sensor 11 installed on the sleepers diagram 5 stops. The grippers 10 are triggered to hold onto the rails enclosing the bench stand 4 of the path 6, the guided stops 13 fall into the gap between the sleepers 5 installed according to the diagram and to be shifted by the diagram step. The guided stops 13 move along a very gentle arc, almost straight, without touching the sleepers laid down on the diagram 5. All commands of the adjuster 14 of the step of the sleepers diagram are reset, and he gives the command to move the carriage 7 to the step of the sleepers diagram. The carriage 7 moves to the step of the plot, shifting the sleepers and the whole row of sleepers in front of it, controlled by stops 13, and stops. Managed stops 13 rise to the upper position. The grips 10 open, and the trolley 1 moves to the next sleeper laid on the diagram. The cycle repeats. To reduce the cycle, moving the carriage 7 to its original position and moving the portal carriage 1 to the sleeper 5 laid on the diagram are combined, which increases the efficiency of use of the device. Zeroing the teams before each commit of the next step allows you to accurately, without incurring errors in the implementation of each next step, place the sleepers on the diagram of the assembled link. The control of the step of the plot from the lateral face of one sleepers to the lateral face of the next is equivalent to the distance of the step of the plot of sleepers between their longitudinal axes.
