Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a loading and unloading structure for steel pipes. Background Art

[0002] In the field of steel pipe processing equipment, most of the current methods use the traditional manual method for loading and unloading. This traditional method has a series of problems. First, a large amount of human resources are required in the process of manual loading and unloading, which increases the labor cost of production and processing and reduces production efficiency. Secondly, manual operation is not only time-consuming and labor-intensive, but also prone to operational errors, leading to errors and delays in production. In addition, during the process of manual loading and unloading, operators need to frequently bend over, lift weights, and so on, which poses a certain risk of work-related injuries and is prone to physical discomfort or even injury, posing a potential threat to the health and safety of workers. Therefore, the traditional manual method of loading and unloading steel pipes has gradually exposed its shortcomings, and a more efficient and safe loading and unloading structure is urgently needed to replace the traditional manual operation method.

[0016] 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.

[0017] See also Figure 1-3The utility model provides a technical solution: a loading and unloading structure for steel pipes, including a feeding box 1 and a conveyor belt 4. The driving structure of the conveyor belt 4 adopts a stepper motor 5. The conveyor belt 4 is supported by a frame 3. The conveyor belt 4 is located at the middle end of the frame 3. The stepper motor 5 is located at the bottom end of the frame 3. A guide bin 2 is provided at the top of the feeding box 1. The upper end of the guide bin 2 is funnel-shaped. The diameter of the through groove at the middle end of the guide bin 2 is adapted to the outer diameter of the steel pipe. A positioning block 6 for separating steel pipes is provided on the outer surface of the conveyor belt 4. A mounting plate 7 is provided on the outer surface of one end of the feeding box 1. A cylinder 9 is installed inside the mounting plate 7.

[0018] A movable groove 8 is opened inside the unloading box 1. The height of the movable groove 8 is greater than the height of the conveyor belt 4. The front and rear ends of the movable groove 8 are hollow structures. The distance controlled by the movable groove 8 and the conveyor belt 4 is intended to ensure that the unloading can remain in close contact, thereby controlling a steel pipe to be limited between every two positioning blocks 6.

[0019] The distance between the top surface of the movable groove 8 and the top of the inner wall of the conveyor belt 4 is the same as the outer diameter of the steel pipe. The distance between the movable groove 8 and the conveyor belt 4 cannot be set larger, otherwise misalignment will occur and transmission will be limited.

[0020] The positioning blocks 6 are evenly spaced and distributed on the outer surface of the conveyor belt 4 , and the positioning blocks 6 are longitudinally arranged in three groups.

[0021] The output end of the cylinder 9 is connected to a rubber pad 11, which is movably connected to the steel pipe. The telescopic stroke distance of the cylinder 9 is greater than half of the length of the steel pipe. The cylinder 9 pushes the steel pipe between the positioning blocks 6 from the surface of the conveyor belt 4 by telescoping. Due to the height difference between the frame 3 and the conveyor belt 4, when the diameter of the steel pipe exceeds half and is outside the surface of the conveyor belt 4, the lever force and gravity are used to tilt the steel pipe and slide it into the guide frame 10, and finally it is transported to the designated position.

[0022] The height of the top of the frame 3 is lower than the height of the top surface of the conveyor belt 4. A guide frame 10 is provided at the top of the frame 3. The guide frame 10 and the cylinder 9 are located on the same longitudinal line. One end of the guide frame 10 is in a trapezoidal structure. The shape and structure of the guide frame 10 can guide the steel pipe and can correct it when the steel pipe is tilted, thereby increasing the overall practicality.

[0023] Working principle: First, stack the steel pipes and place them inside the guide bin 2. The steel pipes are sequentially discharged into the corresponding chute at the middle end of the guide bin 2 and introduced into the positioning blocks 6 arranged on the surface of the conveyor belt 4. Then, the stepper motor 5 is started to put the conveyor belt 4 in motion. The positioning blocks 6 limit the steel pipes and the conveyor belt 4 moves horizontally with them. After the steel pipes move one end distance, the guide bin 2 is discharged into the positioning blocks 6 arranged behind the conveyor belt 4, thus forming a cycle. After the steel pipes are discharged from the movable groove 8, due to the intermittent transmission setting of the stepper motor 5, the conveyor belt 4 will stagnate instead of moving continuously. The cylinder 9 pushes the steel pipes into the guide frame 10 in a telescopic manner and slides them from the guide frame 10 to the specified position. The fully automatic unloading method can effectively increase the unloading efficiency.
