[0052] By tightening the second screw 19 , the second matching plate 15 , the mounting plate 10 and the front plate 8 are pressed against each other.

[0053] The shielding plate 20 is integrally formed with the second matching plate 15 . When the shielding plate 20 rotates to the position of the hand-cranked hole 9 , the shielding plate 20 is blocked between the hand-cranked hole 9 and the screw rod 5 .

The fixed wheel 30 and the universal wheel 31 are welded to the bottom end surface of the fixed rail 1 . The universal wheel 31 is also provided with a locking device 32 .

[0066] The position of the limit plate 22 pointing to the six o'clock direction indicates that the rail is powered on. At this time, the position of the limit plate 22 is the power-on position;

[0067] The position of the limit plate 22 pointing to the three o'clock direction represents that the rail is in a power-off state, and the position of the limit plate 22 is a power-off position;

[0068] Operation process of power failure simulation box 6:

[0069] Simulate the power-on state of the rails. When the power is on, the rotating plate 11 needs to be in the power-on position, the rotating plate 11 needs to be in the three o'clock direction, and the hand-crank hole 9 on the power-off simulation box 6 is in the closed state. At this time, the rotating plate 11 and the limit plate 22 are perpendicular to each other. The rotating plate 11 is limited by the limit plate 22 and the third limit column 21, and the rotating plate 11 cannot be operated. Figure 4 and Figure 5 As shown, the hand crank 7 cannot enter the working state and cannot be manually operated, so as to protect the operator from electric shock;

[0070] Simulate the power-off state of the rails. When the power is off, manual operation can be performed. First, rotate the rotating plate 11 to the power-off position, and then rotate the rotating plate 11 counterclockwise to open the hand-crank hole 9. Figure 6 and Figure 7 As shown, the hand crank 7 can be put into operation to realize manual operation of the hand crank turnout.

[0071] The screw rod 5 is threadedly connected to the through hole of the movable rail 3, and the screw rod 5 adopts reverse thread.

[0072] Not shown in the figure, the invention also includes a hook lock fixing device for locking the fixed rail 1 and the movable rail 3, and the hand crank 7 is inserted into the hand crank hole 9 for manual operation. When the manual operation is completed, the fixed rail and the movable rail on one side are close to each other. At this time, the hook lock fixing device is used to fix and lock the fixed rail 1 and the movable rail 3 from below.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
