The rotating support assembly is arranged at the bottom of the first transverse rail group 11, and the track changing assembly is arranged on the rotating support assembly.

[0032] like Figure 1 and Figure 2As shown, the track changing assembly includes a movable rail 3 and an electric push rod 7. The first transverse rail group 11 includes a first transverse sub-rail 111 and a second transverse sub-rail 112. The movable rail 3 is arranged between the first transverse sub-rail 111 and the second transverse sub-rail 112. The two ends of the electric push rod 7 are respectively connected to the first transverse sub-rail 111 and the movable rail 3 through a rotating bracket 17.

[0033] like Figure 1 and Figure 2 As shown, the rotating support assembly includes a movable beam 4, a rotating shaft 5, a sleeve 6, and a base 18. The top of the movable beam 4 is connected to the bottom of the movable rail 3, one end of the movable beam 4 is connected to the base 18 through the rotating shaft 5, and the sleeve 6 is sleeved on the rotating shaft 5. The movable beam 4 and the base 18 are supported by a pad 16. The base 18 is provided with a slide groove, and the pad 16 is arranged in the slide groove.

[0034] like Figure 1 and Figure 2 As shown, the second transverse sub-rail 112 is provided with a limit plate 10 at one end of the movable rail 3 to prevent the movable rail 3 from deviating from the track after restoration.

[0035] like Figure 1 and Figure 2 As shown, the ends where the movable rail 3 and the first transverse sub-rail 111 are connected are both arc structures in opposite directions, and the ends where the movable rail 3 and the second transverse sub-rail 112 are connected are both arc structures in the same direction.

[0036] like Figure 1 and Figure 2 As shown, the sensing component includes a first sensor 14 and a second sensor 15. The first sensor 14 is arranged on the movable rail 3 and is used to obtain the signal of the second gantry crane 9 moving through the first transverse rail group 11. The second sensor is arranged on the first transverse sub-rail 111 at one end of the movable rail 3 and is used to obtain the signal of the first gantry crane 8 moving through.

[0037] like Figure 1 and Figure 2 As shown, a control method for the above-mentioned height difference rail crossing device includes the following steps:

[0038] S1: When the first gantry crane 8 passes through the transverse rail assembly 1, the controller 13 controls the electric push rod 7 to move and close the movable rail 3 on the first transverse rail assembly 11;

[0039] S2: When the first gantry crane 8 moves to the second sensor 15, the second sensor 15 obtains the position information of the first gantry crane 8 and transmits it to the controller 13. The controller 13 verifies whether the electric push rod 7 closes the movable rail 3;

[0040] S3: When the second gantry crane 9 passes the longitudinal rail assembly 2, the controller 13 controls the electric push rod 7 to rotate the movable rail 3 on the first transverse rail assembly 11 by 90 degrees to open it;

When the first sensor 14 does not obtain a signal, the controller controls the second gantry crane 9 to pass through the first transverse sub-rail 111.

[0042] The working principle of the present invention is as follows:

[0043] like Figure 1-2 As shown, when the present invention is in use, when the first gantry crane 8 passes through the transverse rail assembly 1, the controller 13 controls the electric push rod 7 to move, closing the movable rail 3 on the first transverse rail group 11. At this time, the movable rail 3 and the first transverse sub-rail 111 and the second transverse sub-rail 112 are in a straight line, and the first gantry crane 8 can pass through.

[0044] When the second gantry crane 9 passes through the longitudinal rail assembly 2, the controller 13 controls the electric push rod 7 to rotate the movable rail 3 90 degrees on the first transverse rail group 11 to open it. At this time, there is a gap on the first transverse rail group 11 at the intersection of the first longitudinal rail 21 and the first transverse sub-rail 111, and the second gantry crane 9 can pass through.

[0045] In addition, by setting up the first sensor 14 and the second sensor 15, the displacement of the second gantry crane 9 and the first gantry crane 8 is monitored in real time to ensure that when the second gantry crane 9 and the first gantry crane 8 move, the movable rail 3 is in an open or closed state, so that the second gantry crane 9 and the first gantry crane 8 can pass smoothly.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
