A cylinder 15 carries an auxiliary bogie wheel 14 that can be lifted.

A second vehicle 2 which will be described in more detail with reference to FIG.
The position correcting device is attached to a position corresponding to the joint connecting portion 3 between the first and second vehicles 1 and 2. The second vehicle 2 has a conveyor 16 connected to the conveyor 7 of the first vehicle 1 for the old sleeper tree, which is removed from the upper portion thereof, a conveyor 17 connected to the storage stand 9 of the first vehicle for the new sleeper to be laid, Details of the rail laying stage plate 18 for monitoring the laying work and enabling the operation of each mechanism, the working room 19, and a special sleeper laid at a special place such as a level intersection will be described later. The storage device 20 is carried. The second vehicle 2 has a sleeper removing device 21 for removing an old sleeper which is fed to a conveyor 16 in a lower portion thereof, a plow blade 22 for smoothing or removing a ballast, and a new sleeper laying described later in detail with reference to FIG. Sleeper distribution device 2 coming from device 23, storage device 20
4 and a crawler type support device 25 lifted by, for example, a hydraulic cylinder 26. When the axle 6 is used, the crawler type support device 25, which is lifted for approaching movement on the track, is lowered to the position shown in the figure during this movement and the second vehicle 2 is still railed. It is possible to proceed to place it on a freshly placed sleeper, or alternatively to bring the sleeper closer from the side. The hydraulic cylinder 26A can also be used to fix the orientation of the crawler type support device 25 while acting.

The above-described vehicle is continuously advanced to the left in FIG. 1, that is, traveling on an old rail unbolted by an axle 4, a frame 12, a roller scissors device 13 and the like.
Use to remove the old rails by lifting the old rails, leaving the old sleepers as they are, sliding the old sleepers by the second axle 5 and the auxiliary bogie wheel 14, and removing the sleepers 21.
The old sleeper tree is removed by using the conveyor, and the removed sleeper tree is conveyed by the conveyors 16 and 7 to the storage table 8. The plow blade 22 and related work devices are used to flatten, move, or smooth the ballast, and the new sleeper tree is placed at a location C Is provided, and the vehicle is advanced by the crawler type support device 25 thereon. Then, various works such as laying new rails, laying out ballasts, etc. are carried out by various working devices, which are not included in the scope of the present invention and will not be described here.

The second vehicle 2 is connected to the first vehicle 1 as described above, whereby the location C where the new sleeper is laid is well approximated on the curve locally formed by the railway track. By arranging them in such a manner, the laying of the sleeper tree can be naturally carried out in an extremely close to optimum manner. Only in the case of special singular trajectories, or if for some reason it is desired to change the preceding trajectories, only minor modifications are needed. In order to make these modifications, two horizontal hydraulic cylinders 52, 53 are arranged in the area of the connecting part 3 of the first, second vehicle 1, 2 forming the vehicle, as shown in FIG. Hydraulic cylinders 52, 53 of the second vehicle 2 change the angle A (FIG. 2) formed between the axis of the second vehicle 2 and the axis of the first vehicle 1, whereby the new sleeper laying point C with respect to the railway track.

In addition to the above-mentioned method of correction, various working devices 21 to 24 mounted on the vehicle 2 can be appropriately provided with individual adjusting means for working positions of these devices.

As a work for laying a new sleeper,
Use a gutter or strip that reaches a location near the barrath, and sleep on top of it with sleepers one at a time.
It is a commonly used method to descend one after another by controlling a blocking device for advancing the sleepers one by one, and to place the sleepers on the ballast by dropping the sleepers from the lower end of the gutter or the belt-shaped member. This device often fails, especially in the case of concrete sleepers, as the entire load of its weight is concentrated on the trailing edge below it when the sleeper is at the point of leaving the trough or strip. . Moreover, the variation of the distance between the end of the gutter and the ballas,
And other unanticipated conditions cause some irregularities in the laying of sleepers by this method.

According to the invention, these drawbacks are avoided by the sleeper laying device 23, as shown in FIG.
Trough or strip 17 along which the sleeper descends
Has a bounce plate 47 at its end, and the bounce plate 47 is lowered by a hydraulic cylinder 48, and at the same time, the bounce plate 47 is pivotally attached to a support member 50 fixed to the second vehicle 2 to provide a hydraulic pressure. It has a gripping device 49 which is actuated by a cylinder 51. The gripping of the sleeper by the gripping device 49 is carried out by a scissors device or an electromagnet acting on the area of the rail-supporting metal plate previously attached to the sleeper. The gripping device 49 lifted up to the position shown by the dotted line receives the sleeper that is placed and gripped on the bounce plate 47 each time, and then the bounce plate.
47 is lowered and the gripper 49 positions the sleeper on the ballas by adjusting its position with the desired accuracy. During this operation, no stress concentration occurs on any part of the sleeper, so that the sleeper can be arranged in a completely inconvenient state.

The role of the storage device 20 mounted on the vehicle is to store a special sleeper T for use in a special track area, such as a level intersection. These sleepers are laid at location C by a special laying device 24. As shown in FIG. 5, the storage device 20 is a horizontal conveyor 86 arranged to transfer the special sleepers from the storage device 20 to the laying device 24, and a plurality of the stackers that carry the overlapping stages of the special sleepers T, which are overlapped at equal steps. Pair of horizontal brackets 70, 7
It has a vertical conveyor 69 with 1, 72, etc. When all the sleepers mounted on the horizontal conveyor 68 have been transported out of the storage device 20, the vertical conveyor 69 is lowered by one step, whereby the sleeper T carried by the bottom bracket pair on the horizontal conveyor 68. Position. To allow this work, each bracket has a spacing different from the spacing of the other brackets and the spacing of the horizontal conveyor 68, which spacing increases from bottom to top, for example as shown in FIG. In this way, the bracket 70,
When 71 and the like reach below the level of the horizontal conveyor 68, they are gathered on the both sides of the horizontal conveyor 68 at the level of the vehicle 2 at the position shown by the dotted line in the drawing. With this configuration, a well-organized storage can be performed, a considerable number of sleepers T can be stored in a narrow space, and the sleepers can be loaded and unloaded easily and quickly.
