[0024] As Figures 1 to 5 shown, the utility model provides tower crane steel platform support structure, including:

[0025] Bearing steel beam 1, the top of bearing steel beam 1 is provided with cross beam 2;

[0026] Supporting mechanism, supporting mechanism is set up in the inside of bearing steel beam 1;

[0027] Wherein, supporting mechanism includes tooth plate 3, the outer surface of tooth plate 3 is movably connected with the inside of bearing steel beam 1, the top of tooth plate 3 is fixedly installed with vertical rod 4, sliding groove 5 is set up on vertical rod 4, limiting block 6 is slidably connected in the inside of sliding groove 5, the outer surface of limiting block 6 is fixedly connected with the inside of bearing steel beam 1, the outer surface of tooth plate 3 is engagedly connected with gear 7, rotating block 9 is fixedly installed on the outer surface of gear 7, fixed block 8 is movably sleeved in the inside of rotating block 9 and gear 7, the outer surface of fixed block 8 is fixedly connected with the outer surface of bearing steel beam 1.

[0028] Because the inside of limiting block 6 and sliding groove 5 is slidably connected, therefore limiting block 6 will limit the movement of vertical rod 4 through sliding groove 5, so that vertical rod 4 can only move up and down, when vertical rod 4 moves upward, tooth plate 3 will move upward under the drive of vertical rod 4 at this time, because the outer surface of tooth plate 3 is engagedly connected with the outer surface of two sets of gear 7 respectively, at this time, tooth plate 3 will drive two sets of rotating block 9 to rotate in opposite directions through two sets of gear 7, when two sets of rotating block 9 contact the ground in opposite directions, it will be able to increase the contact area of bearing steel beam 1 and the ground, thereby improving the stability of the overall support of bearing steel beam 1.

[0029] The bottom end of the cross beam 2 is fixedly provided with a supporting block 10, the inside of the supporting block 10 is provided with a bidirectional motor 11, and the other end of the output shaft of the bidirectional motor 11 is fixedly sleeved with a screw rod 12.

[0030] When the bidirectional motor 11 operates, the two screw rods 12 will rotate.

[0031] The outer surface of the screw rod 12 is threadedly sleeved with a moving block 13, and the inside of the moving block 13 is fixedly sleeved with an elongated shaft 14.

[0032] Since the outer surface of the screw rod 12 is threadedly sleeved with the inside of the moving block 13, when the two screw rods 12 rotate, the two moving blocks 13 will be driven to move in opposite directions, and at this time, the two elongated shafts 14 will be driven to move in opposite directions by the two moving blocks 13.

[0033] The outer surface of the elongated shaft 14 is movably sleeved with a moving rod 15, and the other end of the moving rod 15 is hingedly connected with the top end of the vertical rod 4.
