[0005] The bottom plate is an arc-shaped plate protruding downward, the rib plate is provided on the upper side of the bottom plate, the rib plate is provided with a mounting hole, the baffle plates are respectively provided on the left and right sides of the bottom plate, the card block is provided on the outer side of the baffle plate, and the card block is provided with a card slot.
[0006] Furthermore, the bottom plate is an arc-shaped steel plate with a width of 190 mm, a thickness of 15 mm, an arc length of 621 mm, and a steel plate curvature of R4000 mm.
[0007] Furthermore, the ribs are respectively provided at the front and rear ends of the upper side of the bottom plate. The ribs are arc-shaped plates with a thickness of 10 mm. The ribs are provided with two circular mounting holes with a diameter of 40 mm, one distributed on the left and one on the right.
[0008] Furthermore, the thickness of the baffle is 15 mm.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] The card slot of the device can be stuck on the outside of the sleeper and the rail shoulder. With the help of the baffle and the card block, the sleeper and the rail shoulder can be abutted and limited, which can have a good fixing effect, so that a stable structural system can be formed, thereby preventing the shield machine trolley track and the battery car track from moving, ensuring the smooth operation of the shield machine and the battery car. The overall structure of the device is simple, easy to install and disassemble, and highly practical.
