By adjusting the extension length between the first mounting bracket 504 and the first adjusting bracket 505 in the adjusting mechanism 5, the inclination angles of the first bracket 501 and the second bracket 502 are adjusted, and further the extension length and the height of the right end of the third bracket 503 are adjusted. The change in the position of the third bracket 503 further changes the position and height of the hanging basket, making the adjustability of the construction hanging basket enhanced.

[0028] In this embodiment, referring to Figure 2 and Figure 3As shown, the first mounting bracket 504 and the first adjusting bracket 505 are respectively rotatably connected to the second bracket 502 and the third bracket 503 through rotating shafts. A slider 508 is rotatably mounted below the second mounting bracket 506, and the slider 508 is slidably connected to the chassis 3. The upper end of the second adjusting bracket 507 is rotatably connected to the right end of the third bracket 503 through a rotating shaft. Threaded rods 510 are provided in both the first mounting bracket 504 and the second mounting bracket 506. Second bevel gears 512 are provided in both the first mounting bracket 504 and the second mounting bracket 506. Locking mechanisms 6 are provided on both the first mounting bracket 504 and the second mounting bracket 506. The lower end of the threaded rod 510 penetrates through the first mounting bracket 504 or the second mounting bracket 506 and is rotatably connected to the first mounting bracket 504 or the second mounting bracket 506 through a bearing. The upper end of the threaded rod 510 penetrates through the first adjusting bracket 505 or the second adjusting bracket 507 and is threadedly connected to the first adjusting bracket 505 or the second adjusting bracket 507. A first bevel gear 511 is sleeved on the threaded rod 510, and the second bevel gear 512 is meshed with the first bevel gear 511. By rotating the rotating rod 601, the second bevel gear 512 is driven to rotate, and the threaded rod 510 is rotated by cooperating with the meshed first bevel gear 511. Under the limiting action of the first mounting bracket 504 or the second mounting bracket 506, the extended lengths of the first adjusting bracket 505 and the second adjusting bracket 507 are respectively adjusted. By rotating the lead screw 509, the position of the slider 508 mounted below the second mounting bracket 506 in the chassis 3 is adjusted, and then the inclination angles of the first bracket 501 and the second bracket 502 are adjusted, so that the position of the third mounting bracket is changed according to actual needs, and the height and fixed position during the use of the hanging basket are changed to meet the actual needs of bridge construction.

[0029] In this embodiment, referring to Figure 4 and Figure 5As shown, the latch mechanism 6 includes a rotating rod 601 fixedly installed with the second bevel gear 512. An installation tube 602 is sleeved on the rotating rod 601. The rotating rod 601 is rotatably connected to the first mounting bracket 504 or the second mounting bracket 506 through bearings. The installation tube 602 is fixedly installed in the corresponding first mounting bracket 504 or second mounting bracket 506. Four groups of symmetrically distributed rubber latch blocks 603 are provided on the installation tube 602. A sleeve 604 is threadedly sleeved on the installation tube 602, and a tapered sleeve 605 is provided on the sleeve 604. The tapered sleeve 605 is movably clamped with the rubber latch blocks 603. A latch rod frame 607 is provided on the left side of the sleeve 604, and four groups of symmetrically distributed card slots 606 are provided on the sleeve 604. The latch rod frame 607 is movably clamped with the sleeve 604 through the card slots 606. The outer wall of the sleeve 604 is threadedly connected to the corresponding first mounting bracket 504 or second mounting bracket 506. By driving the sleeve 604 to rotate in the first mounting bracket 504 or the second mounting bracket 506 through the latch rod frame 607, the position of the tapered sleeve 605 is adjusted. When the tapered sleeve 605 is firmly clamped with the four groups of rubber latch blocks 603, the four groups of rubber latch blocks 603 are tightly attached to the outer wall of the rotating rod 601, restricting the rotation of the rotating rod 601, thereby restricting the rotation of the second bevel gear 512 and fixing the positions of the first adjusting bracket 505 and the second adjusting bracket 507.

[0030] In this embodiment, referring to Figure 6 As shown, the extension mechanism 7 includes two groups of extension rods 701 symmetrically distributed in the cross frame 4. Both groups of extension rods 701 are slidably connected to the cross frame 4. A bidirectional screw rod 702 is provided in the cross frame 4, and both ends of the bidirectional screw rod 702 respectively penetrate through the two groups of extension rods 701 and are threadedly connected to the two groups of extension rods 701. A third bevel gear 703 is sleeved on the bidirectional screw rod 702. A fourth bevel gear 704 is provided in the cross frame 4. The fourth bevel gear 704 is meshed and connected with the third bevel gear 703. By rotating the bidirectional screw rod 702, the extension lengths of the two groups of extension rods 701 can be adjusted under the limiting action of the cross frame 4, and thus the transverse installation width of the hanging basket can be adjusted.

[0031] During the operation of this embodiment, the rotation of the rotating rod 601 drives the rotation of the second bevel gear 512. The rotation of the threaded rod 510 is achieved by cooperating with the first bevel gear 511 that is meshed and connected thereto. Under the limiting action of the first mounting bracket 504 or the second mounting bracket 506, the extended lengths of the first adjusting bracket 505 and the second adjusting bracket 507 are adjusted respectively. By the rotation of the lead screw 509, the position of the slider 508 installed below the second mounting bracket 506 within the chassis 3 is adjusted, and then the inclination angles of the first bracket 501 and the second bracket 502 are adjusted, so that the position of the third mounting bracket is changed according to actual needs, changing the height and fixed position during the use of the hanging basket to adapt to the actual needs of bridge construction. In this device, the rotation of the sleeve 604 in the first mounting bracket 504 or the second mounting bracket 506 is driven by the lever frame 607 to adjust the position of the tapered sleeve 605. When the tapered sleeve 605 is firmly clamped with the four rubber locking blocks 603, the four rubber locking blocks 603 are tightly attached to the outer wall of the rotating rod 601, restricting the rotation of the rotating rod 601, and further restricting the rotation of the second bevel gear 512, fixing the positions of the first adjusting bracket 505 and the second adjusting bracket 507. By the rotation of the bidirectional screw 702, the extended lengths of the two extension rods 701 can be adjusted under the limiting action of the cross frame 4, and further the lateral installation width of the hanging basket can be adjusted.

The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
