The lifting chain 63 is set with several redirecting sprockets. The two ends of the lifting chain 63 are respectively connected to the rotary table frame 31 and the counterweight 62. The lifting motor 61 and the lifting chain 63 control the lifting and lowering of the rotary table frame 31.

[0032] like Figure 2 The rotary table 3 includes a rotary table frame 31, a box girder 36, a cargo rail 32, a fall arrestor 34, and a rotary drive assembly 35. The rear side of the rotary table frame 31 is mounted on the hoist frame 1 and can move up and down. The hoist drive assembly 6 is used to drive the rotary table frame 31 to move up and down. The box girder 36 is rotatably mounted on the front side of the rotary table frame 31. The box girder 36 is connected to the cargo rail 32 by several tie rods. The rotary drive assembly 35 is used to drive the cargo rail 32 to rotate. The rotary drive assembly 35 includes a rotary drive motor 351 and a transmission chain 352. The rotary drive motor 351 drives the rotary shaft to rotate through the transmission chain 352, sprockets, and other structures. The rotary shaft is connected to the box girder 36.

[0033] The cargo track 32 is provided with docking tracks 33 installed on the turntable frame 31 on both sides. The docking tracks 33 are used to connect the overhead track 2 and the cargo track 32.

[0034] Four sets of fall arrestor components 34 are provided, with two sets on each of the front and rear sides of the rotary table frame 31, forming stable support for the front and rear of the rotary table frame 31.

[0035] like Figure 4 The fall arrestor 34 includes a positioning block 342 and a positioning block motion drive. The positioning block motion drive is used to drive the positioning block 342 to switch between a supported state and a retracted state. The fall arrestor support 7 is used to support the positioning block 342 when it is in the supported state. When the positioning block 342 is in the retracted state, it avoids interference with the up and down movement of the rotary table.

[0036] In this embodiment, the positioning block motion drive is a positioning block rotation drive assembly, which includes a drive cylinder 341. The positioning block 342 is mounted on the rotary table frame 31 via a rotating shaft 345. The two ends of the drive cylinder 341 are hinged to the positioning block 342 and the rotary table frame 31, respectively.

[0037] The fall arrestor assembly 34 also includes a limiting structure, which is used to support and limit the positioning block 342 when it is in a supported state, so as to prevent the positioning block 342 from falling. The limiting structure is a limiting post 343, and a hydraulic buffer 344 is installed on the limiting post 343.

[0038] Preferably, the positioning block 342 is a wedge-shaped block with an inclined surface on its upper surface.

[0039] like Figure 3 Four sets of fall protection support components 7 are set up, which are respectively installed on the hoist frame 1 and the support beam 21 used to fix the aerial track 2. The fall protection support component 7 includes a support rod 71, the height of which can be adjusted. The support rod 71 is a screw. The fall protection support component 7 also includes a nut 72, which can be fixed on the hoist frame 1 / support beam 21. The support height can be adjusted by rotating the support rod 71.

[0040] In other embodiments, the support rod 71 may be equipped with support pads, and the support height can be adjusted by installing different numbers of pads.

[0041] A flexible buffer pad 73 is provided at the contact position between the support rod 71 and the positioning block 342.

[0042] By installing anti-fall components 34 at both the front and rear sides of the turntable frame 31, a stable support is formed for the turntable 3, ensuring the stability of the turntable 3 when the cargo track 32 connects with the overhead track 2, preventing it from settling, and achieving the anti-fall effect.

[0043] Working principle: Taking the above-ground operation as an example: The rotary table 3 is equipped with four sets of anti-fall components 34 at the four corners, and correspondingly, four fall support components 7 are set on the hoist frame and steel structure. The positioning block 342 extends and retracts when in the high position, and rests on the four support rods 71 ​​when in the middle position, which plays the role of preventing falls and stabilizing the loading platform.

[0044] Before the suspended vehicle enters the hoist, the rotary table 3 is in the middle position, with the cargo rail connected to the overhead rail. The positioning block 342 rests on the four support rods 71 ​​to ensure that the cargo rail is aligned with the overhead rail. After the suspended vehicle enters the designated position on the rotary table 3, the lifting motor raises the rotary table 3 to the high position via the lifting chain. Then, the positioning block 342 retracts (to ensure that it does not interfere with other components during the lifting process), and the rotary table 3 lowers to the low position, at which point the winding machine begins single-sided winding.

[0045] After the single-sided winding is completed, the rotary drive assembly 35 inside the rotary table 3 rotates the loading track 180°, and the winding machine begins the back-side winding operation.

[0046] After the wire feeding operation is completed, rotate 180° in the opposite direction to return to the original position. The rotary table 3 rises to the high position, the positioning block 342 extends, and then descends to the middle position, resting on the buffer bar. At this time, the cargo aluminum rail is aligned with the fixed aluminum rail in the air, and the suspended vehicle drives away from the rotary elevator.

[0047] Example 2:

[0048] Based on Embodiment 1, in this embodiment, a support platform 4 is installed on the hoist frame 1, and a rotating support body 5 for supporting the suspended vehicle is provided on the support platform 4. The rotating support body 5 is a rotatable disc structure. After the suspended vehicle enters the turntable, the turntable 3 descends to the working position, and the suspended vehicle comes into contact with the rotating support body 5, thereby supporting the suspended vehicle and ensuring safety during operation. When the turntable 3 drives the suspended vehicle to rotate, the rotating support body 5 rotates together.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments.
