[Problems to be solved by the invention]
By the way, unlike road construction, track improvement and track maintenance work has a special feature that it must be performed in a short time from the last train to the first train.
However, in the conventional sleeper fixing device, because of the structure, it is not possible to quickly and easily perform the attachment and detachment of the sleepers and the replacement of the parts, so it is practically difficult to reliably complete these operations in a short time, This will lead to an increase in construction and maintenance costs and a longer construction period.
Then, the subject of this invention is providing the fixing device of the sleeper which can complete | finish the attachment or detachment operation | work of a sleeper or the replacement | exchange of components reliably in a short time.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, a sleeper fixing device according to the present invention is fixed to a sleeper support member that supports a sleeper having a trapezoidal cross section in a side view, and receives end portions of the sleeper from the front and rear and the lateral direction, respectively. Members, and front and rear pads provided on the front and rear surfaces of the end of the sleeper, respectively, and on the side ends of the end receiving member, and are in contact with the side end surfaces of the end of the sleepers. A side end pad is provided.
[0006]
According to such a sleeper fixing device, since the end receiving member and the side end receiving pad are provided, the sleeper can be fixed to the end receiving member by the side end receiving pad, and the sleeper can be attached and detached and the parts can be replaced. It becomes possible to carry out quickly and easily.
Therefore, the sleeper attaching / detaching operation and the component replacement operation can be completed in a short time, and thereby the construction cost and maintenance cost can be reduced and the construction period can be shortened.
[0007]
In such technical means, the point of view to allow the exchange of sleepers detachable and parts more quickly and easily, interposed wedge pad before and after the end receiving member.
[0008]
Further, as it is easily attached wedge pad, the groove and butt viewpoint et al to allow the exchange of sleepers detachable and parts even more quickly and easily, front and rear pad, extending laterally to the inner surface The strips are alternately formed continuously, and the wedge pad is formed with the grooves of the front and rear pads and the grooves and projections that fit the strips alternately on the outer surface thereof, and the wedge pad is shifted laterally. It was possible to remove .
[0009]
Furthermore, the front and rear pads are set to different thickness dimensions from the standpoint that the wedge pads of different thickness dimensions can be easily attached and the height of the sleepers can be adjusted quickly and easily. It is preferable.
[0010]
Furthermore, from the viewpoint of making it possible to easily and variably set the gap dimension between the end receiving member and the sleeper and also to quickly and easily adjust the planar position of the sleeper, the end receiving member and It is preferable that an adjusting member for adjusting the position of the sleeper in the lateral direction is provided between the side end receiving pads.
