DETAILED DESCRIPTION

[0024] Example 1, please refer to Figures 1 to 2 , which is a schematic diagram of a container elevator and conveying production line provided by the present invention. The container elevator comprises: a protective frame 10, a horizontal conveying frame 20 disposed outside and connected to the protective frame 10, and a lifting assembly 30 and a buffer weighing assembly 40 disposed inside the protective frame 10. It is conceivable that the container elevator also includes other functional components and specific structures, such as electrical connection components, control components, and mounting structures, all of which are well known to those skilled in the art and will not be described in detail here.

[0025] The protective frame 10 is a vertical rectangular frame. The bottom of the protective frame 10 is connected to the ground or a flat base. The four sides of the protective frame 10 are assembled by surrounding vertical protective nets. A vertical lifting channel 11 is formed in the middle of the protective frame 10. The lifting channel 11 provides external protection and displacement guidance for the lifting component 30 to avoid the problem of container tipping over or material spillage during the lifting process.

[0026] The outside of the protective frame 10 is provided with a delivery opening 12 arranged at intervals. The delivery opening 12 can be multiple and opened at different heights of the protective frame 10. In this embodiment, there are two delivery openings 12 and they are located on both sides of the protective frame 10. The delivery openings 12 are connected to the lifting channel 11. A horizontal conveyor frame 20 is connected to the outside of the protective frame 10 at the delivery opening 12 position. The upper end of the horizontal conveyor frame 20 is connected to the lower end of the delivery opening 12. The horizontal conveyor frame 20 adopts a roller conveying method. The upper end of the horizontal conveyor frame 20 is provided with a conveying roller 21 and a driver for driving the conveying roller 21. The driver is a motor. The horizontal conveyor frame 20 is used to input the container into the lifting channel 11 or the lifting channel 11 is output horizontally outward. It can be imagined that this container elevator is mainly used in storage workshops. The container is an empty barrel or a lightweight container with a small load. The lightweight container is transported to the upper end space by the lifting assembly 30, forming a storage space with a light top and a heavy bottom.

[0027] See also Figures 1 to 3The lifting assembly 30 comprises a lifting frame 31 vertically arranged in the lifting channel 11, a guide sliding block 34 connected to one side of the lifting frame 31, a guide rail 35 vertically arranged on the inner wall of the lifting channel 11 and matched with the guide sliding block 34, a lateral support provided by the protection frame 10, the lifting frame 31 can vertically displace along the guide rail 35 through the guide sliding block 34, and the guide sliding block 34 is driven by a lifting motor 36. Optimally, the guide sliding block 34 is provided with a roller 37 rolling and matched with the outer side of the guide rail 35, the guide structure is reduced in friction through the matching mode of the roller 37 and the guide rail 35, the lifting smoothness is improved, the lifting motor 36 is arranged at the upper end, and the lifting motor 36 is connected with the guide sliding block 34 through a drag chain, the force of the drag chain is controlled, and the stroke of the guide sliding block 34 is accurately controlled.

[0028] The lifting frame 31 is connected with an inner conveying platform 32 at the upper end, the inner conveying platform 32 is provided with a frame structure with a wide upper end and a narrow lower end, the inner conveying platform 32 is provided with a conveying roller 21 at the upper end, a bidirectional driving motor 33 is installed in the space at the bottom of the inner conveying platform 32, the bidirectional driving motor 33 is matched with the conveying roller 21, the conveying direction on the inner conveying platform 32 is realized through the forward and reverse output of the bidirectional driving motor 33, the position of the container on the inner conveying platform 32 can be adjusted, and the power can be provided for the container to enter or move out of the lifting channel 11. In the embodiment, the lifting frame 31 is connected to the middle lower end of the inner conveying platform 32, and the lower end of the inner conveying platform 32 tends to be a trapezoidal cross-section structure.

[0029] Please refer to Figure 1 and Figure 4The buffer weighing assembly 40 includes a buffer bracket 41 arranged at the bottom of the lifting channel 11. The buffer bracket 41 is set on the ground or connected to the bottom of the protective frame 10 to increase the bottom counterweight of the protective frame 10 and improve the structural reliability. Four buffer support blocks 42 that can elastically press against the bottom of the lifting frame 31 are provided at intervals at the upper end of the buffer bracket 41. The buffer support blocks 42 are arranged at the corners of the buffer bracket 41, and the upper ends of the buffer support blocks 42 are flat surfaces. The four buffer support blocks 42 are spaced apart and fit against the bottom of the circumferential edge of the built-in conveying platform 32, which lowers the center of gravity of the built-in conveying platform 32 and enables the weight of the built-in conveying platform 32 to be evenly distributed and pressed down on the buffer support blocks 42. Specifically, a vertically arranged load-bearing channel 44 is provided at the upper end of the buffer bracket 41, and a spring 45 is provided in the load-bearing channel 44. A guide column 46 that penetrates into the load-bearing channel 44 and squeezes the spring 45 is provided at the bottom of the buffer support block 42. The vertical buffer structure can avoid unilateral tilting of the built-in conveying platform 32 and ensure the stability of the built-in conveying platform 32 during the container receiving process. It can be imagined that when the built-in conveying platform 32 is pressed down on the buffer weighing assembly 40, relying on its own weight, the height of the built-in conveying platform 32 remains flush with the height of the horizontal conveying rack 20, enabling the container to be smoothly conveyed from the horizontal conveying rack 20 to the built-in conveying platform 32.

[0030] It can be imagined that the outer wall of the guide column 46 located on the outside of the load-bearing channel 44 is provided with a limiting boss 47, and the buffer bracket 41 is connected to a limiting sleeve 48 that is sleeved on the outside of the guide column 46 and limits the upward movement of the limiting boss 47. Through the cooperation between the limiting sleeve 48 and the limiting boss, the guide column 46 is prevented from separating from the buffer bracket 41, and the maximum height of the buffer support block 42 is limited to ensure the installation stability of the buffer support block 42.

[0031] In addition, a weighing module 43 is provided on the buffer bracket 41, which can be against the bottom of the lifting frame 31. The structure of the weighing module 43 itself is the existing technology. The upper end of the weighing module 43 is in contact with the bottom of the lifting frame 31. When the container is transferred to the built-in conveying platform 32, the total weight of the container and the material in the container can be obtained. By identifying the weight of the container, it is avoided to transport heavy containers to high places, reducing the load-bearing pressure of the elevator and increasing its service life.

[0032] In addition, guide side plates 22 are provided on both sides of the horizontal conveying rack 20 and both sides of the built-in conveying platform 32. The guide side plates 22 are used to guide the horizontal conveying of the container between the horizontal conveying rack 20 and the built-in conveying platform 32 to avoid collision between the container and the protective frame 10 during the conveying process.

[0033] Example 2: The present invention also provides a conveying production line having a container elevator as described above. Except for the container elevator, other components are existing technologies or commercially available parts.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
