Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figures 1-5As shown, this utility model provides a quick-assembly tower crane material hoisting bucket, mainly comprising a bucket body 1 and four support columns 2. The four support columns 2 form a stable rectangular frame through connecting columns 3. The bucket body 1 is fixed to the inner side of this frame.

[0022] A locking mechanism 4 is provided at the top of each support column 2. The top of each support column 2 is equipped with the same locking mechanism 4 to ensure the stable fixation of the bucket body 1.

[0023] The locking mechanism 4 includes a latch 41 and a positioning rod 42. The latch 41 has a U-shaped structure, with its first end 411 being longer than its second end 412. The top of the support column 2 has a sliding groove 21 and a insertion groove 22. The first end 411 of the latch 41 is slidably connected within the sliding groove 21. The inner wall of the sliding groove 21 is designed to be narrower on the outside and wider on the inside to facilitate the sliding and positioning of the first end 411 of the latch 41.

[0024] The second end 412 of the latch 41 is inserted into the insertion groove 22. A limiting hole 23, penetrating the support column 2, is provided in the insertion groove 22. A through hole 413, corresponding to the limiting hole 23, is provided on the second end 412 of the latch 41. A positioning rod 42 is slidably connected within the limiting hole 23. When the second end 412 of the latch 41 is inserted into the insertion groove 22, the positioning rod 42 passes through the through hole 413 and the limiting hole 23 of the latch 41, thereby locking the latch 41 in the insertion groove 22.

[0025] To facilitate positioning and locking, a push plate 43 is provided on the positioning rod 42, positioned outside the limiting hole 23 for easy operation. A mounting bracket 5 is also provided on the support column 2 outside the limiting hole 23. The push plate 43 is connected to the mounting bracket 5 via a spring 44, which is sleeved on the outside of the positioning rod 42. This structure allows the positioning rod 42 to be pushed to the locked position by the spring 44 when no external force is applied. When unlocking is required, the spring force of the spring 44 can be overcome by pulling the pull ring 45 at the end of the positioning rod 42, thereby pulling out the positioning rod 42 and releasing the lock.

[0026] Within the sliding groove 21, a limiting block 414 is provided at the bottom of the first end 411 of the latch 41. The function of the limiting block 414 is to contact the edge of the sliding groove 21 after the latch 41 slides to a certain position, thereby limiting the latch 41 and preventing it from sliding excessively, thus ensuring the positioning accuracy of the latch 41.

[0027] The bottom of the bucket body 1 is provided with a discharge port 11. An arc-shaped bottom plate 6 is provided at the discharge port 11. The design of the arc-shaped bottom plate 6 allows the material to slide out more smoothly. Fixed seats 12 are provided on both sides of the discharge port 11. The two sides of the arc-shaped bottom plate 6 are rotatably connected to the fixed seats 12 through a rotating shaft, so that the arc-shaped bottom plate 6 can switch between opening and closing the discharge port 11 around the rotating shaft.

[0028] To achieve automated discharge control, a rotating seat 13 is provided on the bucket body 1. A cylinder 7 is mounted on the rotating seat 13. The output end of the cylinder 7 is rotatably connected to a connecting seat 61 provided on the arc-shaped base plate 6. By controlling the extension and retraction of the cylinder 7, the connecting seat 61 and the arc-shaped base plate 6 can be rotated, thereby achieving precise control of the discharge port 11, such as automatically opening the discharge port 11 for unloading.

[0029] Each support column 2 is equipped with casters 8 at its bottom. The installation of casters 8 allows the hopper to be easily moved and positioned on the ground, improving the flexibility of the construction site.

[0030] Working principle:

[0031] Pull the ring 45 at the end of the positioning rod 42 to overcome the elastic force of the spring 44, causing the positioning rod 42 to disengage from the limiting hole 23 and the through hole 413 of the latch 41. At this time, the latch 41 can slide. Slide the first end 411 of the U-shaped latch 41 to the appropriate position, put the lifting ring on the latch, and then push the second end 412 into the insertion groove 22. Finally, release the push plate 43, and under the action of the spring 44, the positioning rod 42 returns to its original position, passes through the through hole 413 and the limiting hole 23 of the latch 41, thereby firmly locking the latch 41 in the insertion groove 22.

[0032] The locked hopper is suspended by the lifting rings of the tower crane for hoisting. As needed, the discharge port 11 is opened manually or by controlling the arc-shaped base plate 6 via cylinder 7 to discharge the material.
