Description

[Detailed description of the invention] The invention is designed to allow a bogie to transfer to a transfer rail that is connected to the traveling rail at a required slope and is movable along the main rail without damaging the tip of the rail. This article relates to the structure of the rail joint section.

In recent years, as a method of concrete pouring for dams, etc.
As shown in Fig. 1, the hotspa station 2 is made to be able to be raised along the rail 1 laid on the slope, and the hotspa station 2 is raised as the level of concrete placement increases. Even if the concrete is displaced, it is possible to transfer the concrete from the hotspa station 2 to the dump truck 3, etc., and the concrete is supplied to the hotspa station 2 by using the rails 1 and 4 installed on the hotspa station 2. There is one that is carried out by a traveling bucket truck 12.

In this method, the rail 4 provided at the hotspot station has its tip, which is the connection part with the rail 1 laid on the slope, cut at an acute angle. For this reason, the strength of the leading edge (especially the leading edge) is weakened, and the running wheels of the bucket truck 12 are at the leading edge of the rail 1.
This is the part that receives the most severe impact when transferring from the rail 4 to the rail 4, and if the bucket cart 12 transfers frequently, the leading end will wear and break.

The present invention was developed in consideration of the actual situation,
During transfer, the trolley is temporarily run on the flange of the running wheel, and by lifting the running wheel above the rail while running on the flange, the load is not applied to the tip, which is weak in strength. .

Embodiments of the present invention will be described below based on the drawings.

Figure 2 is an enlarged view of section A in Figure 1, and Figure 3,
4 and 5 are views taken in the direction of arrow B, arrow C, and arrow D of FIG. 2, respectively, and FIG. 6 is a perspective view of the tip of the transfer rail.

A joint part 5 extending further from the tip of the transfer rail and sandwiching the running rail 1 is provided at the tip of the transfer rail 4 whose tip is cut off at an acute angle.

The joint portion 5 is fixed to or integrally formed with the side surface of the transfer rail 4, and the upper end surface is a flange rolling surface 8 having a width that allows the flange 7 of the wheel 6 to run. The surface 8 has a required level difference from the running surface 9 of the transfer rail 4 and the running surface 10 of the running rail 1 at the tip.

At the tip of the joint portion 5, as shown in FIG.
The height difference h between the outer peripheral surface of the wheel 6 and the outer peripheral surface of the wheel 6 should be equal to the height difference h, and the height difference between the running surfaces 10 and 9 and the rolling surface 8 should gradually become smaller than the height difference h near the tip of the transfer rail 4. The outer circumferential surface of the wheel 6 is raised so that it can run using the flange 7, and the step between the running surface 9 and the rolling surface 8 is gradually increased on the transfer rail 4 side from near the tip of the transfer rail 4. At the base, the flange 7 is completely raised above the rolling surface 8 as shown in FIG.

In addition, numeral 11 in the figure is a guide provided to prevent slippage.

Therefore, when the cart transfers to the transfer rail 4, the wheels 6 pass without contacting the tip of the transfer rail 4, and no impact force is applied to the tip. Furthermore, the running surfaces 9 and 10 having different slopes are gently connected by the rolling surface 8, and the impact caused by sudden changes in slope is also alleviated.

Although the above embodiment is a case in which the present invention is applied to a bucket cart, it goes without saying that the present invention can be applied not only to a bucket cart but also to any cart that transfers from a horizontal running rail to an inclined transfer rail. Of course, it is also effective when transferring to.

As described above, according to the present invention, it is possible to prevent wear and tear at the tip of the transfer rail which has a required slope with respect to the running rail and is movable along the running rail.
