[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a special hopper for lifting blocks, such as Figure 1-Figure 4 As shown, it includes a protective frame 1, two load-bearing rods 3 are installed at the bottom of the protective frame 1, and the two ends of the load-bearing rods 3 are fixed to the protective frame 1 by pins 4. A clamping assembly 6 is installed on the inner side of the top of the protective frame 1, and a plurality of positioning protrusions 5 are installed on the side of the protective frame 1 close to the two ends of the load-bearing rods 3. The load-bearing rods 3 are adjusted in height according to the size of the hoisted blocks, and are fixed on the positioning protrusions 5 at different heights by pins 4. The clamping assembly 6 includes an upper pressing plate 61 and a lower pressing plate 62, and the upper pressing plate 61 and the lower pressing plate 62 are connected by a guide assembly. The top of the upper pressing plate 61 is rotatably connected to a threaded rod 66 through a bearing, and the threaded rod 66 is threadedly connected to the top plate of the protective frame 1.

[0023] Specifically, the special hopper for lifting blocks mainly includes a protective frame 1, which constitutes the main structure of the hopper and provides stable support and protection for the blocks. Two load-bearing rods 3 are installed at the bottom of the protective frame 1. These two load-bearing rods are the main load-bearing structures of the blocks in the hopper. They span the bottom of the hopper to ensure the stability and safety of the blocks during lifting. The two ends of the load-bearing rods 3 are fixed to the protective frame 1 by pins 4. This fixing method is both firm and easy to adjust. The design of the pin 4 allows the load-bearing rods 3 to be easily installed, disassembled or adjusted when necessary.

[0024] In order to adapt to blocks of different sizes, a plurality of positioning convex plates 5 are installed on the side of the protection frame 1 near the two ends of the load-bearing rod 3. These positioning convex plates provide multiple fixing points for the load-bearing rod 3, so that the height of the load-bearing rod 3 can be adjusted according to the size of the hoisted blocks. When the load-bearing rod 3 is adjusted to a suitable height, it is fixed to the positioning convex plate 5 at the corresponding position by the latch 4, thereby ensuring the stability of the blocks during the hoisting process.

[0025] A clamping assembly 6 is installed on the inner side of the top of the protection frame 1. The clamping assembly consists of an upper pressing plate 61 and a lower pressing plate 62, which are connected by a guide assembly. The function of the clamping assembly is to fix the blocks tightly in the hopper through the relative movement of the upper pressing plate and the lower pressing plate after the blocks are put into the hopper to prevent movement or collision during the lifting process.

[0026] In order to facilitate the adjustment of the pressure of the clamping assembly 6, a threaded rod 66 is rotatably connected to the top of the upper clamping plate 61 through a bearing. The threaded rod is threadedly connected to the top plate of the protective frame 1, so that by rotating the threaded rod, the height of the upper clamping plate 61 can be easily adjusted, thereby controlling the pressure of the clamping assembly 6 on the building blocks.

[0027] In this embodiment, the side of the protection frame 1 is composed of a plurality of vertical bars, a top plate is provided on the top, and the bottom is open. The overall structure is a rectangular parallelepiped, which makes it easy to insert the building blocks into the inner side of the protection frame 1.

[0028] Specifically, two lifting rings 2 are installed on the top of the protection frame 1 to facilitate lifting of the protection frame 1 .

[0029] Furthermore, the load-bearing rod 3 is a long plate-like structure with pin holes 31 provided at both ends. The long plate-like structure facilitates the load-bearing rod 3 to bear the weight, and the pin holes 31 facilitate the positioning of the two ends.

[0030] Furthermore, the end of the latch pin 4 is provided with a threaded end, and the outer end of the latch pin 4 is locked and fixed by a locking nut 41 .

[0031] Furthermore, protrusions 11 are installed at the bottom of both sides of the protective frame 1, and the protrusions 11 are provided with through holes. The ends of the pins 4 pass through the pin holes 31 and the through holes of the protrusions 11 and are locked and fixed by locking nuts 41, so that the two ends of the load-bearing rod 3 are fixed.

[0032] Furthermore, a through hole is provided on the surface of the positioning protrusion 5. When the height of the load-bearing rod 3 needs to be adjusted, the load-bearing rod 3 is removed from the bottom of the protective frame 1, moved upward, and the end of the pin 4 is passed through the pin hole 31 and the through hole of the positioning protrusion 5 and is locked and fixed by the locking nut 41, so that the load-bearing rod 3 is fixed on the positioning protrusion 5.

[0033] Furthermore, the guide assembly includes a guide sleeve 63 and a guide column 64. The guide sleeve 63 is slidably connected to the guide column 64. A spring 65 is arranged in the guide sleeve 63. The top end of the spring 65 is welded and fixed to the guide sleeve 63. The bottom end of the guide sleeve 63 is welded and fixed to the lower pressure plate 62. The top of the guide sleeve 63 is welded and fixed to the upper pressure plate 61. The bottom end of the guide column 64 is welded and fixed to the lower pressure plate 62. The guide assembly ensures the stability of the movement of the lower pressure plate 62 and provides a certain buffer space to avoid damage during transportation.
