[0002] Chinese patent document CN210479649U discloses a hopper for hoisting loose materials on a tower crane. It proposes that both ends of the hopper are rotatably connected to support shafts extending from the side walls of the hopper. A cover plate is fixed to the middle of each support shaft. The two cover plates rotate towards each other to a horizontal position, abutting against each other and sealing the upper side of the hopper. Hanging plates are also fixed to both ends of the support shaft. Lifting cables are fixed to the two hanging plates on the same support shaft, and lifting lugs are fixed to the middle of each lifting cable. The two lifting cables drive the hanging plates at both ends of the hopper to move towards each other, which in turn causes the support shaft to rotate until the two cover plates cover the hopper. This design effectively prevents the hoisted material from spilling out of the hopper during hoisting, resulting in high safety.

[0003] The aforementioned solution and existing technology utilize a hopper, a widely used lifting and hoisting tool in construction engineering. It can carry a wide variety of items, including blocks, liquids, and powders. According to relevant national regulations and company rules, the hoisted items should generally not exceed the hopper's capacity. However, in actual use, improper operation by personnel often results in items exceeding the hopper's capacity, posing a safety hazard of falling objects during hoisting and failing to meet practical usage requirements.

[0004] Therefore, this utility model proposes an overload-proof hoisting hopper with a protective cover to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides three technical solutions for an overload-resistant hoisting hopper with a protective cover:

[0024] Example 1: An overload-proof hoisting hopper with a protective cover, comprising: a hopper body 1 and an arc-shaped lifting block 2; the arc-shaped lifting blocks 2 are fixedly arranged at equal intervals on the upper end surface of the hopper body 1;

[0025] The hopper body 1 is equipped with protective components and auxiliary components.

[0026] Example 2: Based on Example 1, the protective components include a protective door 3 and a steel wire mesh 4. The protective door 3 is located on the upper surface of the hopper body 1, and a steel wire mesh 4 is fixedly installed inside the protective door 3. A hollow iron fan-shaped column slot 5 is provided on the upper surface of the protective door 3 corresponding to the arc-shaped lifting block 2. The protective door 3 is movably connected to the hopper body 1 through a hinge 6. When the hopper is overloaded, the protective door 3 is not completely closed, and the hollow iron fan-shaped column slot on the protective door 3 will cover the hopper hook, making it impossible to connect the hopper to the crane hook, i.e., it cannot be lifted. When the hopper is not overloaded, the protective door 3 can be completely closed, the hopper hook is exposed, and the operator can connect the hopper to the crane for lifting.

[0027] Fixed rods 7 are fixedly installed at equal intervals on the right protective door leaf 3, and a movable plate 8 is movably installed on the fixed rods 7. A positioning rod 9 is movably inserted into the movable plate 8, and one end of the positioning rod 9 is connected to the connecting plate 10. The other end of the positioning rod 9 is movably inserted into the positioning hole on the left protective door leaf 3. Movable rods 11 are fixedly installed at equal intervals at the bottom of the connecting plate 10, and the movable rods 11 are movably inserted into the movable hole on the left protective door leaf 3. A washer 12 is provided on the outer wall of the positioning rod 9, and a connecting spring 13 is provided between the washer 12 and the movable plate 8.

[0028] Example 3: Based on Example 2, the auxiliary components include a positioning plate 14 and a positioning groove 15; the positioning plate 14 is fixedly installed on the protective door leaf 3 at equal intervals, and the positioning groove 15 is fixedly installed on the inner side wall of the positioning plate 14.

[0029] The hopper body 1 has movable grooves 16 fixedly arranged at equal intervals on its side, and movable plates 17 are movably arranged in the movable grooves 16. One side of the movable plate 17 is connected to the movable grooves 16 by a movable spring 19. The other side of the movable plate 17 is provided with a positioning protrusion 18, and the positioning protrusion 18 is adapted to and connected to the positioning groove 15 on the inner side of the positioning plate 14.

[0030] In use, after the hopper body 1 is loaded with materials, the protective door 3 connected to the hopper body 1 by the hinge 6 is closed, and the positioning groove 15 on the positioning plate 14 on one side of the protective door 3 is positioned and connected to the positioning protrusion 18 on the side of the hopper body 1. Then, the moving plate 8 at the end of the fixing rod 7 is rotated, and the connecting plate 10 connected to the positioning rod 9 on the moving plate 8 is moved upward and then released. Under the action of the connecting spring 13, the positioning rod 9 moves downward until it enters the positioning hole of the left protective door 3, and the movable rod at the bottom of the connecting plate 10 passes through the left protective door 3, positioning the left and right protective doors 3. This can prevent the materials inside the hopper body 1 from being overloaded. When the hopper is overloaded, the protective door 3 is not completely closed, and the iron hollow fan-shaped column slot on the protective door 3 will cover the hopper hook, making it impossible to connect the hopper to the crane hook, i.e., it cannot be lifted. When the hopper is not overloaded, the protective door 3 can be completely closed, the hopper hook is exposed, and the operator can connect the hopper to the crane for lifting.
