[0016] One end of the first diagonal member 17 is connected to the upper part of the vertical frame 8. One end of the second diagonal member 18 is connected to the lower part of the vertical frame 8. That is, one end of the second diagonal member 18 is located below one end of the first diagonal member 17. Further, the other end of the first diagonal member 17 is connected to a portion of the vertical edge closer to the vertical column 13 than the vertical frame 8. The other end of the second diagonal member 18 is connected to a portion of one horizontal member 15 in the depth direction that is closer to the vertical column 13 than the vertical frame 8.

[0017] Between the other vertical frame 9 and the other vertical column 14, there is a first diagonal groove having one end connected to the vertical frame 9 and the other end connected to the vertical edge of the car floor 11. A member 19 and a second diagonal member 20 having one end connected to the vertical frame 9 and the other end connected to the longitudinal edge of the car floor 11 are arranged. [0018] One end of the first diagonal member 19 is connected to the upper part of the vertical frame 9. One end of the second diagonal member 20 is connected to the lower part of the vertical frame 9. That is, one end of the second diagonal member 20 is located below one end of the first diagonal member 19. Further, the other end of the first diagonal member 19 is connected to a portion of the vertical edge closer to the vertical column 14 than the vertical frame 9. The other end of the second diagonal member 20 is connected to a portion of the other horizontal member 15 in the depth direction that is closer to the vertical column 14 than to the vertical frame 9.

In this example, each support member 23 is arranged on a straight line connecting each second corner of the car floor 11 and the center part of the lower frame 6.

[0021] The dimensions of each support member 23 in the vertical direction are larger on the lower frame 6 side than on the second corner side. That is, each support member 23 is a trapezoidal plate-like member formed such that the dimension in the vertical direction decreases as the distance from the lower frame 6 increases.

[0022] Each support member 23 is fixed to the lower frame 6 and the protrusion member 22 by a plurality of screws 24 arranged at intervals in the vertical direction.

[0023] FIG. 2 is a sectional view showing the car floor 11 and support device 21 of FIG. 1. In the figure, a car floor leveling device 25 is provided between the car floor 11 and the support member 23 to adjust the car floor 11 to be horizontal. In this example, the car floor leveling device 25 is provided at the tip of the support member 23 on the side away from the lower frame 6.

[0024] The car floor horizontal adjustment device 25 includes a fixed part 26 horizontally fixed to the support member 23, an adjustment bolt 27 screwed into a screw hole of the fixed part 26, and passed vertically through the fixed part 26. It has a locking nut 28 for fixing the position of the adjustment bolt 27 with respect to the fixing part 26.

[0025] The second corner of the car floor 11 is placed on the adjustment bolt 27. In this example, the adjustment bolt 27 is in contact with the lower surface of the car floor 11. Also, the position of the adjustment bolt 27 in the vertical direction with respect to the fixing part 26 is as follows: It can be adjusted by adjusting the total amount. Therefore, by adjusting the amount of threading of the adjustment bolt 27 into the screw hole of the fixing part 26, the inclination of the power cage floor 11 with respect to the support member 23 is adjusted, and the car floor 11 is adjusted horizontally.

[0026] Further, the car floor 11 and the support member 23 are provided with a position fixing device 29 for fixing the position of the car floor 11 with respect to the support member 23. The position fixing device 29 has a fixing metal fitting 30 fixed to the lower surface of the car floor 11 and a tightening bolt 31 for fastening the fixing metal fitting 30 to the support member 23.

[0027] The fixture 30 is arranged along the side surface of the support member 23. A long hole 32 is provided in the fixing metal fitting 30 along the vertical direction. The fixture 30 is fastened to the support member 23 by a fastening bolt 31 passed through an elongated hole 32. The position of the fixture 30 relative to the support member 23 is fixed by tightening the fastening bolt 31 to the support member 23. Further, the fixing fitting 30 can be displaced along the elongated hole 32 with respect to the supporting member 23 by loosening the fastening bolt 31.

[0030] That is, for example, when the load is concentrated on one of the second corners and the barracks 11 receives an uneven load, part of the uneven load is near the second corner that received the uneven load. The truss structure formed by the first diagonal member 17 on the side and the longitudinal edge of the car floor 11 is transmitted to one vertical frame 8, and a portion of the remaining unbalanced load is transferred to one supporting member 23. From, bottom frame 6, other support member 23, other vertical column 1 4, and is transmitted to the other vertical frame 9 via the truss structure formed by the other depth direction horizontal member 15 and the other second diagonal member 20. The load transmitted to each vertical frame 8, 9 is supported by each car guide rail 3 via each guide shoe 10. Therefore, part of the unbalanced load received by the car floor 11 can be transmitted to each vertical frame 8, 9 via the truss structure, reducing the bending stress acting on each vertical frame 8, 9. can do.

[0031] This eliminates the need to strengthen the car floor 11, each of the vertical frames 8, 9, and the bottom frame 6, making it possible to prevent an increase in material costs and an increase in the weight of the car 2. Therefore, the specifications of the equipment such as the power car guide rail 3, the main rope, and the unloading machine can be made into standard specifications, and the uneven load that the car floor 11 receives can be easily supported with a simple configuration.

[0032] Furthermore, with such a structure, even if the car floor 11 receives an uneven load, the bending and tensile forces generated in the car floor 11 can be reduced, so that the structure of the car floor 11 can be reduced. You can increase your degree of freedom. For example, the structure of the car floor can be made into a structure that incorporates a vibration isolating material, and it is possible to prevent a decrease in riding comfort for passengers in the power car 2. In this case, the car floor consists of a rectangular floor support frame placed on the lower frame 6, four vibration isolators placed at the four corners of the floor support frame, and floor members placed on each vibration isolator. It consists of Further, the support member 23, the first diagonal member 17, and the vertical columns 13, 14 are connected to the floor support frame.

[0033] Furthermore, each support member 23 is fixed to the lower frame 6 by a plurality of screws 24 arranged at intervals in the vertical direction, so that each support member 23 is fixed to the lower frame 6 in the vertical direction. Strength can be increased. Therefore, even if the car floor 11 receives an uneven load, it is possible to further prevent the occurrence of large bending of the car floor 11.

[0034] Furthermore, between each support member 23 and the car floor 11, a car floor leveling device 25 is provided to adjust the cage floor 11 to be horizontal. Even if the car floor 11 is tilted for some reason, the car floor 11 can be adjusted horizontally.

[0035] Furthermore, the car floor horizontal adjustment device 25 has an adjustment bolt 27 on which the car floor 11 is placed, and by adjusting the position of the adjustment bolt 27 in the vertical direction with respect to the support member 23, the car floor 11 can be adjusted. Since it is designed to adjust horizontally, it is possible to adjust the weight floor 11 horizontally with a simple configuration.
