Hereinafter, the configuration and operation of the present invention will be described with reference to embodiments shown in the drawings. FIGS. 1, 2, 3, and 4 are a cross-sectional view and a vertical cross-sectional view, respectively, before, during, and after conversion of the front-end branching device conversion device of the present invention. In these figures, the base 1 of the front end branch is uniformly lowered from the baseway 2 of the guideway, and the single-sided side walls 4 are set up on the left and right sides of the roadbed by the inner surface width of the sum of the inner width of the guideway and the thickness of the both side walls 3. Form bridge 5
Is placed on the base 1 of the front end branch. Under the U-shaped bridge 5, there is provided a roller 6 which can move laterally on the surface of the base 1.

The height of the subway 2 of the U-shaped bridge 5 is the same as that of the guideway, and the front and rear ends of the subbase 2 of the U-shaped bridge 5 are retracted from the front and rear ends of the single-sided side wall 4 so as to be between the subway 2 and the guideway. Is provided with a gap 8 perpendicular to the straight road.

A towing truck 9 moving on the base is inserted into the gap 8, and the double-sided side wall 3 is fixed thereon. A conveyor chain 10 that goes around the base 1 through the gap 8 at both ends of the towing car 9
Conveyor chain 10 at the exit of the gap 8 in the base 1
Is attached. A motor 13 with a speed reducer and a brake device 14 are connected to the sprocket shaft 12, and a conveyor chain that appears on the roadbed.
10 is a chain 15 with a lid.

The operation at the time of turning-off of the branching device is performed by rotating the motor with speed reducer from the state in which the right side wall 4 of the U-shaped bridge 5 of FIG. 1 is sandwiched between the both side walls 3 and the right stopper 7 in FIG. Until both sides contact the left side wall 4 of the U-shaped bridge 5 as shown in FIG.
To the left. Furthermore, move both side walls 3 to the left,
As shown in FIG. 3, the U-shaped bridge 5 is also pushed and moved to the left until the U-shaped bridge 5 hits the left stopper 7 so that the inner surfaces of the left and right side walls coincide with the path side. After that, when the brake is applied by the brake device to fix the double-sided side wall 3 so as not to move, the U-shaped bridge 5 is fixed together because the left single-sided side wall 4 is sandwiched between the double-sided side wall 3 and the stopper 7. The gap 8 in the roadbed 1 is covered with a chain 15 with a lid to eliminate irregularities on the roadbed surface, thereby changing the course of the front end branch.

FIGS. 5, 6, and 7 are plan views of the straight path of the branch and the course of the branch using the conversion device of the present invention, respectively, and before the branch is assembled.

In these figures, the side-translation type branching device of the U-shaped guideway of the superconducting magnetic levitation railway is composed of two types of branching devices, a front branching device and a rear branching device. Each of the branching devices is constituted by a single-sided side wall 4 provided with the coils 16 provided on the left and right sides of the roadbed 2 on the inside, and a double-sided side wall 3 provided with the coils 16 provided therebetween on the left and right sides. The shape is such that the side walls facing each other form a pair, and have the same linear shape and branched curve shape, respectively.

For reasons of mounting the coil 16 and strength, the both side walls 3 have an appropriate thickness at the front end, and both front and rear end surfaces are perpendicular to a straight path. Inside the turnout, two side walls 3 for the thin front end turnout and the thick rear end turnout 3
Is provided. And in the front end branching device, both side walls 3
Is translated until it comes into contact with the side wall 4 on the closed side,
The U-shaped bridge 5 placed on the base is moved laterally to the closed side by the thickness of the front end of the double-sided side wall 3, and the closed-side single-sided side wall 4 of the U-shaped bridge 5 is sandwiched between the stopper 7 and the double-sided side wall 3 and fixed. Has been converted.

In the rear end branch device, left and right single-sided side walls 4 are fixed to the roadbed 2, and the thick double-sided side walls 3 are placed between them. The double-sided side wall 3 is placed on a towing truck 9 placed in a groove 17 traversing the roadbed 2, and the towing truck 9 is pulled by the conveyor chain 10 until the double-sided side wall 3 contacts the one-sided side wall 4 on the closed side. By moving in parallel, the course of the rear end branch is changed.

〔The invention's effect〕

According to the present invention, the double-sided side wall and the U-shaped bridge can be translated accurately and quickly to the normal position together by the action of the groove guide and the stopper, and the brake operation to the conveyor chain for the double-sided side wall towing is performed. In addition, it is possible to develop a conversion device for a front-end branching device for a superconducting magnetic levitation railway which can easily and securely fix not only a double-sided side wall but also a U-shaped bridge.
