Description

[0001]
[Industrial application fields]
The present invention relates to a temporary stand for track rails.
[0002]
[Prior art]
When replacing track rails or correcting track rails, a so-called low floor is used as a temporary table that supports the track rails by arranging them in an appropriate number along the direction in which existing sleepers are juxtaposed. The low floor roller has a configuration in which a roller body is pivotally attached to a support piece of a base frame in which a support piece is erected on both ends of the base piece so as to be rotatable about a support shaft. .
[0003]
[Problems to be solved by the invention]
The low-floor roller according to the above structure can be practically used as a guide for moving the track rail along the direction in which the sleepers are juxtaposed or for temporarily supporting the track rail. Is limited to a straight road, there is a risk that it will come off the roller body on a curved road, and even on a straight road, it will come off from the roller body due to external forces such as vibration due to train passage, and therefore, temporarily, Applicable only on straight roads.
[0004]
The present invention was devised for the purpose of providing a temporary placement base for a rail for a track that can be used in a relatively wide range while avoiding the limitation in use of such a conventional example.
[0005]
[Means for Solving the Problems]
A pair of support pieces are erected in the longitudinal direction of the sleepers on a base placed on an existing sleeper, and a roller for mounting the track rail is pivotally supported by the support pieces. on the opposite sides of the support shaft, that assembled freely undulating opposing regulation piece with the track rails on the roller when standing the basic unit, the rectangular outline form, in the longitudinal direction of the contour feature A long elongated hole is biased to one side in the longitudinal direction to form a restricting piece, and when the restricting piece is assembled with the elongated hole penetrating a support shaft, By providing a stopper in contact with one end along the longitudinal direction of the piece adjacent to the restriction piece, the restriction piece can be easily erected or laid down as necessary to provide a temporary table that is easy to use. be able to.

【Example】
FIG. 1 is a partially cutaway front view of FIG. 1, FIG. 2 is a plan view of a regulation piece lying down, and FIG. It is a sectional view taken on the line a.
[0007]
The temporary table A of the embodiment is arranged such that a new track rail R is arranged adjacent to the existing rail instead of the existing track rail currently in use, and then temporarily used for the track until the replacement work. It is applied as a support for the rail R, and is placed on one end in the longitudinal direction of the sleeper m, and is arranged with an interval of 5 to 6 m along the parallel direction of the sleeper m, that is, the longitudinal direction of the existing rail. Of course, there is no problem even if it is applied as a so-called low floor roller.
[0008]
In the figure, reference numeral 1 denotes a base of the temporary mounting table A, and the base 1 is formed by superimposing the first constituent material 1A and the second constituent material 1B on each other, and fastening them with bolts 2 and nuts 3 together. It is composed of the component 1B, and further includes a pair of support pieces 4 and 4 erected in the longitudinal direction of the sleeper m, and one end portion of the support pieces 4 and 4 is provided with a long hole. The handle 5 is made of the first component 1A and can be carried by the handle 5.
[0009]
On the support pieces 4 and 4 of the base 1, a support shaft 6 made of a bolt rod with a nut screwed to a tip is fastened and assembled, and the roller 7 is attached to the support pieces 4 and 4 by the support shaft 6 . 4 is pivotally supported on both sides of the support shaft 6, and a restricting piece 8 is rotatably mounted on both sides of the support shaft 6.
[0010]
The roller 7 has a length that allows the track rail R to be placed on its axis, and is supported by the support shaft 6 so that it can freely rotate. Although it is configured, there is no inconvenience even if resin or iron is used as a material.
[0011]
The restricting piece 8 is arranged adjacent to the support piece 4 on both sides of the support shaft 6 via the roller 7 on the inner side thereof, and is rectangular (not necessarily rectangular, and in short, if one side is long) A long hole 9 that is long in the longitudinal direction is provided on the one side in the longitudinal direction of the contour body, and is assembled to the support shaft 6 so as to penetrate through the long hole 9. It is attached.
[0012]
Further, since the restriction piece 8 is assembled to the support shaft 6 in the long hole 9 that is displaced to the one end 8 ′ in the longitudinal direction, one end of the long hole 9 on the one end 8 ′ side of the restriction piece 8. When the support shaft 6 is relatively positioned at 9 ′, the support shaft 6 is in a lying state, and as shown in FIGS. 1 and 3, the support shaft 6 is supported at the other end 9 ″ in the longitudinal direction corresponding to the one end 9 ′. when the shaft 6 is relatively position and standing, I said (to) is placed on the roller 7 are to the track rail R that faces so. That is, the restriction piece 8 rotates around the support shaft 6 due to the assembly relationship with the support shaft 6 in the long hole 9, and rises when the longitudinal side of the long hole 9 extends along the vertical direction, and extends along the horizontal direction. When falling, the rail R is prevented from coming off or falling from the roller 7 in the former state.
[0013]
Then, when the restriction piece 8 is erected on the inner side of the support piece 4 so as to be adjacent to the restriction piece 8 (when the longitudinal side of the restriction piece 8 extends in the vertical direction), the elongated hole 9 extends in the longitudinal direction. A stopper 10 made of a long ridge is provided, and one end 8a along the longitudinal direction of the restricting piece 8 is brought into contact with and separated from the stopper 10, and the restricting piece 8 is rotated in the lying down direction by the contact of the stopper 10. When being regulated and lying down, the restriction piece 8 is lifted and the position of the long hole 9 relative to the support shaft 6 is shifted from the one end 9 ′ side to the other end 9 ″ side for the first time. 6 can be rotated in the direction of lying down.
[0014]
Note that the stopper 10 does not need to be configured by a protrusion provided on the support piece 4 as in the embodiment, and may be erected on the base 1 like the support piece 4.
[0015]
In short, any structure may be used as long as it is located adjacent to the restricting piece 8 and the one end 8a of the restricting piece 8 contacts and separates due to the synergistic action with the long hole 9.
[0016]
Thus, the temporary placement table A is arranged along the longitudinal direction of the existing rail (the direction in which the sleepers m are juxtaposed) with appropriate intervals so as to be placed on the sleepers m. Are placed on the roller 7 at the end of the temporary table placed side by side, for example, a new track rail R is pushed and the rail R is moved to the roller 7. It is guided and moves along existing rails, and is arranged as desired without deviating from the moving direction due to the presence of the restricting pieces 8 and 8 even on some curved roads.
[0017]
And even if vibration is given by the passing train with being supported on the roller 7, the fall of the rail R from the control piece 8 roller 7 is controlled.
[0018]
When the rail R is arranged at the track position, or when the restriction piece 8 is not used from the beginning, the restriction piece 8 is lifted up using the engagement relationship between the long hole 9 and the support shaft 6, and then The restriction piece 8 is used in a lying state by rotating around the support shaft 6.
[0019]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a temporary mounting table suitable for moving or mounting the rail for the track by arranging an appropriate number along the direction in which the sleepers are juxtaposed. . In particular, since it is provided with a restriction piece facing the track rail placed on the roller, the rail fallen from the roller by the restriction piece during the movement operation of the rail guided by the roller. Therefore, the moving operation can be performed smoothly, the moving operation can be performed without any inconvenience on some curved roads, and the rails can be received in response to external loads such as vibration from the train. It is possible to provide a temporary table that can reliably maintain the support state and can be used in the same manner as a normal low floor roller.
