Description

  The present invention relates to a track carriage and a ladder-type sleeper transporting device that travels on a track rail and is generally used for transporting articles to the site for maintenance and inspection of railway tracks.

A guide rail that extends in a direction perpendicular to the track rail is provided on a pedestal for the loaded article, and a pair of wheel bodies including guide rollers that roll along the guide rail are movably assembled to the cradle, and the pair of wheels The other end of each intermediary piece whose one end is pivotally connected to the opposite side of the body is pivotally connected to the end of the connecting piece pivotally attached to the cradle at the center, and Each wheel body has a configuration in which traveling wheels that travel on track rails are rotatably provided.

  The present invention can also be applied to the case of the left side, and was devised to provide a track carriage suitable for transporting loaded articles such as ladder-type sleepers.

  A guide rail is provided on the pedestal for the loaded article, and a pair of wheel bodies including guide rollers that roll along the guide rail are movably assembled to the cradle, on the opposite sides of the pair of wheel bodies. The other end of each intermediary piece with one end pivotably connected is pivotally connected to the end of a connecting piece pivotally attached to the cradle at the center, and each wheel body has a track. A traveling wheel that travels on the rail is configured to be rotatable.

  According to the present invention, the connecting piece and the mediating piece pivotally connected to the connecting piece constitute a link mechanism so that the wheel bodies connected to the mediating pieces are brought close to and separated from each other, and the degree of the approaching and separating is set. Thus, the traveling wheel can travel on the track rail while following the space between the track rails, and therefore, a carriage corresponding to the track rail having a different track can be provided.

  Moreover, the ladder-type sleeper transport device according to the present invention is connected to a rail portion having a wider gauge at the sleeper replacement site. Place a dolly movably, load a ladder sleeper between the dolly pedestals, and move it from the rail section of the sleeper transport location to the rail position of the sleeper replacement site while maintaining the loaded state. Can do. That is, the ladder type sleepers on the cradle are lifted up using the Yamakoshi device (known) to the rail part position, and while the lifted state is maintained, each carriage is returned from the corresponding point to the sleeper carrying point while the ladder type Suspend the sleepers and lay them down (if necessary, repeat the transport of the ladder sleepers by means of a cart), and after laying, put the rail part with the gap between the rails back on the ladder sleepers. It is suitable for rail replacement work that uses ladder-type sleepers as new sleepers that are placed and fixed and returned to the track rails in the normal state.

  FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a side view showing a state in which a ladder sleeper is being transported, and FIG. 4 is a plan view of FIG. 5 is a partially enlarged view, FIG. 5 is a side view of FIG. 4, and FIG. 6 is a partially cutaway front view showing the relationship between the cradle and the link mechanism.

In the track carriage A of the embodiment, the center portion of the link mechanism 2 is assembled at the center of the cradle 1, and the wheel body 3 is rotatably assembled at both ends of the link mechanism 2. the roller 4 with combined rollably guide rail 1A extending at right angles of the track rail R provided on the cradle 1, the trajectory of the traveling wheel 5 is placed rollably on the track rail R It travels along the rail R, and conveys the ladder-type sleepers L loaded on the cradle 1, 1 of the pair of front and rear carts A, A arranged along the track rail R. is there.

The cradle 1 is composed of a slightly flat H-shaped cross section formed by placing horizontal parts 1b and 1b 'relative to each other above and below the vertical part 1a. The connecting piece 7 of the link mechanism 2 is rotated at the center in the longitudinal direction through the spacer 6 at the center in the longitudinal direction of the lower horizontal portion 1b ′ of the cradle 1. It is pivotally attached.

Linkage 2, one end of the intermediary piece 9 to each of both ends of the connecting piece 7 and the connecting piece 7 with the connecting pins 8 connected rotatably, the other end of the intermediary piece 9 of each of the wheel assembly 3 The wheel frame 10 is pivotally connected to the wheel frame 10 by a connecting pin 11.

  The wheel body 3 is configured by providing side pieces on both sides of the central piece, and the lower frame portions 10a and 10b are arranged in an orthogonal direction so as to be connected to each other at the central piece. And a pair of front and rear guide rollers 4 and 4 are pivotally mounted between side pieces of the upper frame portion 10a of the wheel frame 10, and between the side pieces of the lower frame portion 10b. In this case, the pair of front and rear traveling wheels 5 and 5 are pivotally supported.

  Then, the wheel body 3 is combined with the cradle 1 so that the guide roller 4 is engaged with the guide rail 1A using the lower horizontal portions 1b and 1b ′ as a guide material on the cradle 1, The traveling wheels 5 of the wheel bodies 3 combined on both sides of the cradle 1 are placed on the track rail R, and are assembled to the projecting piece 10 b ′ provided on the lower frame portion 10 b of the wheel frame 10 and the cradle 1. The pair of carts A and A are arranged on the track rail R so as to be freely movable by directly connecting the end portions of the mediating pieces 9 of the combined link mechanism 2 to each other by the connecting pins 11.

  Thus, the ladder-type sleepers L are stacked on the track rail R so as to pass over the pair of front and rear carts A, A arranged along the longitudinal direction of the rail R, and are placed on the upper frame portion 10a of the wheel frame 10. The ladder-type sleepers L are fixed to the carriage A with a rope m by using the locking ring 12 provided and used so as to be transported to the site.

  During the transfer movement to the sleeper replacement site, the gap between the track rails R gradually becomes wider at the replacement site, but the connecting piece 7 rotates as the traveling wheel 5 moves along the track rail R. Then, the guide roller 4 connected to the connecting piece 7 via the mediating piece 9, that is, connected via the link mechanism 2, moves along the guide rail 1A following the traveling of the traveling wheel 5, and the carriage A The movement corresponding to the distance between the rails of the track rail R is performed without any trouble.

Then, the ladder-type sleeper L is moved from the rail part of the conveyance place to the rail part position of the sleeper replacement site, and the ladder-type sleeper L is lifted from the cradle 1 using the Yamakoshi device (known). While maintaining the state, return each cart A from the relevant location toward the sleeper carrying location, and suspend and lay the ladder-type sleeper L (if necessary, repeat the transport of the ladder-type sleeper L with the cart) To do.

  In addition, after laying, on the said ladder type sleeper, the said rail part which extended the gauge was put back and mounted and fixed, and a rail exchange operation is completed by returning to the track rail in a normal state.
