Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a portal of gantry crane, including girder 1, the below of girder 1 is provided with the Y-shaped supporting leg 4 that four symmetries set up, U-shaped fixed block 5 has all been welded at the top of Y-shaped supporting leg 4, there is adjusting block 9 all through bolted connection in the inside of U-shaped fixed block 5, L-shaped fixed block 2 has all been welded at the top of adjusting block 9, and girder 1 is located the inside upper surface of L-shaped fixed block 2, fixedly connected with supporting steel plate 7 between two Y-shaped supporting legs 4 that are located the right side, supporting steel plate 7's last fixed surface is connected with hydraulic stem 8, and hydraulic stem 8 is located the below of girder 1.

In this embodiment, the bottom of the Y-shaped support leg 4 is provided with a pulley 13, and the pulley 13 is matched with an external rail.

In this embodiment, fixedly connected with slide rail 11 is all established to the front and the back of girder 1, and sliding connection has electric block 12 on two slide rails 11.

In this embodiment, a plurality of searchlights 14 are installed at the bottom of the main beam 1 and are arranged at equal intervals.

In this embodiment, the upper end of U-shaped fixed block 5 all sets up the second screw hole 6 that a plurality of equidistance were arranged, and the third screw hole 10 that a plurality of equidistance were arranged is seted up to the inside of adjusting block 9, and second screw hole 6 and third screw hole 10 phase-match.
