Description

Technical Field

[0001] This utility model relates to the field of pipe casting production equipment, and in particular to a moving station device for ductile iron pipes. Background Technology

[0002] In the production of ductile iron pipes, the pipe casting process requires the coordinated completion of multiple steps, with each step corresponding to an independent processing station. Therefore, the transfer of pipes between adjacent stations is a crucial link in connecting the production line and ensuring production continuity. Due to the inherent characteristics of ductile iron pipes, finished or semi-finished products are hard and relatively heavy. The efficiency and stability of their movement between stations directly affect the processing rhythm and product quality of the entire production line.

[0003] Currently, the industry still largely relies on traditional methods for moving ductile iron pipes between adjacent workstations: some small and medium-sized production lines use manual labor with simple tools for handling. Due to the large weight of the ductile iron pipes, manual handling not only requires a large amount of manpower but also presents significant time and labor costs. Each transfer takes a long time, and improper human control during handling can easily lead to collisions, causing surface damage or dimensional deviations. Even when some production lines introduce mechanical assistance, they mostly use forklift transport or fixed-track conveyor structures. Forklift transport requires sufficient operating space and demands high operator skills. It lacks flexibility in workshops with densely packed workstations and is prone to interference with other equipment. Fixed-track conveyor structures are limited by the track laying path and can only adapt to workstations with specific spacing. If the production line adjusts the workstation layout or changes to ductile iron pipes of different diameters, the track needs to be redesigned, resulting in poor adaptability and high adjustment costs, making it difficult to meet the needs of flexible production.

[0004] With the increasing demand for ductile iron pipe production capacity, the requirements for automation and efficiency in production lines are rising. The inefficiency, high labor costs, and low adaptability of traditional moving methods are becoming increasingly prominent, posing a bottleneck to improving production line efficiency. Especially in continuous production scenarios, if the transfer of cast iron pipes between workstations cannot match the processing speed of each process, it can easily lead to pipe accumulation at upstream workstations and work stoppages at downstream workstations due to material shortages, severely impacting production continuity. Therefore, developing a moving device that can automatically transfer cast iron pipes, adapt to the layout of adjacent workstations, and operate stably to solve the problems of time-consuming, labor-intensive, and inefficient traditional methods has become an urgent need to ensure the efficient operation of ductile iron pipe production lines. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a moving station device for ductile iron pipes, which aims to solve the problem of inefficient handling of ductile iron pipes and can facilitate the convenient and efficient handling of ductile iron pipes between stations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a ductile iron pipe moving station device, including a first processing station and a second processing station for pipe casting that are suspended in the air. The length of the first processing station and the second processing station for pipe casting is less than the length of the pipe casting. A motor with the same specifications is also provided on both sides. An L-shaped rotating arm with the same specifications is connected to the output shaft of each motor. The short end of the rotating arm is connected to the output shaft of the motor, the long end is set upward, and a pipe frame is provided at the end of the long end.

[0007] A further improvement of the present invention is that: a horizontally extending connecting shaft is provided at the end of the long end of the rotating arm, a bearing is sleeved at the end of the connecting shaft, and a U-shaped tube frame with an upward opening is connected through the bearing.

[0008] A further improvement of this utility model is that the main body of the pipe frame is U-shaped, and the specific structure is that the top is a horizontal beam, the middle of the beam is fitted on the bearing, and a U-shaped frame with an upward opening is connected below the beam. The opening is connected to the beam, and a horizontally extending U-shaped plate is connected to the U-shaped frame. The opening size of the U-shaped plate is larger than the diameter of the cast pipe.

[0009] A further improvement of this utility model is that a rubber gasket is provided at the bottom of the U-shaped plate.

[0010] A further improvement of this utility model is that two parallel positioning rails are provided on both sides of the bottom of the motor, and the motor is sandwiched between the positioning rails to ensure that the positions of the motors on both sides are relative.

[0011] A further improvement of this utility model is that the motor is controlled by a PLC and is periodically turned on according to the production speed of the production line.

[0012] The technological advancements achieved by this invention, due to the adoption of the aforementioned technical solutions, are as follows: By setting a linkage structure between a motor with periodic start and a rotating arm, the motor can start periodically according to the production speed of the production line, and drive the rotating arm to rotate counterclockwise around the motor shaft at a suitable slow speed. This provides stable power for the transfer of cast pipes, replacing traditional manual handling or complex transmission methods. This avoids the problems of time-consuming, labor-intensive, and inefficient manual handling, resulting in a significant reduction in labor intensity and an improvement in the efficiency of cast pipe transfer. Furthermore, by setting a connection structure between the bearing and the pipe frame, and utilizing the rotational characteristics of the bearing and the weight of the pipe frame itself, the pipe frame maintains a vertically upward U-shaped opening throughout the entire rotational motion of the rotating arm. This ensures that the pipe frame can stably hold the processed cast pipe at one station, and that the cast pipe will not tilt, slip, or be bumped during the transfer process. This avoids the problem of easy damage to the cast pipe in traditional transfer methods, resulting in the protection of the appearance and structural integrity of the cast pipe and improved stability during transfer. By integrating the motor, rotating arm, pipe frame and bearing into an integrated moving device, the automatic transfer of cast pipes from one station to two adjacent stations can be realized directly. There is no need to equip multiple sets of auxiliary equipment or manually intervene for adjustment. It can accurately adapt to the continuous production rhythm of the production line, avoid the problem of station connection jams in the traditional transfer method, and bring about the effects of reducing the transfer connection time between stations, ensuring the continuous operation of the production line, and further improving the overall production efficiency.

[0018] The present invention will be further described in detail below with reference to embodiments:

[0019] like Figure 1Figures 2 and 3 show a schematic diagram of a ductile iron pipe moving station device, including a first processing station 1 and a second processing station 2 for storing and holding pipes suspended in mid-air. Each station has the same specifications, with a flat middle and raised ends. The pipe 7 can be stored on the station. The length of the first processing station 1 and the second processing station 2 is less than the length of the pipe 7, that is, when the pipe 7 is stored on the station, both ends extend beyond the station. The station can be a single unit or, in this embodiment, a station composed of two smaller units. The distance between the ends of the two smaller units is still less than the length of the pipe 7, ensuring that both ends of the pipe 7 can extend beyond the station. At the outer center of the first and second workstations, two identical motors 3 are symmetrically arranged on both sides. Each motor 3 has an L-shaped rotating arm 4 of identical specifications connected to its output shaft. The L-shaped rotating arm has a short end and a long end, which are perpendicularly connected. The short end of the rotating arm 4 is connected to the output shaft of the motor 3, while the long end faces upwards. Rotation of the motor 3's output shaft drives the rotating arm 4 to rotate in a plane. The plane of rotation is located on the outer sides of both ends of the cast pipe. The rotating arm 4 rotates freely without interfering with the cast pipe. Furthermore, the two rotating arms 4 maintain the same angle and speed while rotating. A horizontally extending connecting shaft is provided at the long end of the rotating arm 4. A bearing 5 is fitted at the end of the connecting shaft, and a U-shaped tube frame 6 with an upward opening is connected through the bearing 5. The main body of the tube frame 6 is U-shaped, specifically with a horizontal crossbeam at the top. The middle of the crossbeam is fitted onto the bearing 5, allowing the crossbeam to rotate freely. A U-shaped frame with an upward opening is connected below the crossbeam, and the opening is connected to the crossbeam. The U-shaped frame is closed, and a horizontally extending U-shaped plate is connected to the U-shaped frame. It is a curved plate, which can be understood as a straight plate bent into a curved surface to form a U-shaped pocket. The opening size of the U-shaped plate is larger than the diameter of the cast pipe 7, and it is not closed at the top, allowing a section of the cast pipe to be freely, flexibly, and conveniently inserted into the pocket of the U-shaped plate and thus moved. A rubber gasket is provided at the bottom of the U-shaped plate, which increases friction to stably fix the cast pipe and ensures soft contact to prevent damage to the outer surface of the cast pipe.

[0020] Two parallel positioning rails are set on both sides of the bottom of the two opposing motors 3. The two motors 3 are sandwiched between the positioning rails, which can effectively ensure that the motors 3 are accurately aligned and that there is no positional deviation. At the same time, a base with rollers can be set under the motors 3 for easy movement and adjustment. The motors 3 are connected to the PLC and controlled by the PLC, and are periodically turned on according to the production line speed. The two motors 3 on both sides start once at a certain period of time (matched to the production line speed). Each time the motor 3 starts, it drives the rotating arm 4 to rotate counterclockwise at a suitable slow speed with the motor output shaft as the center, providing power for the entire device. The top of the rotating arm 4 is connected to the tube frame 6 through the bearing 5. Due to the weight of the bearing 5 and the tube frame 6 itself, the U-shaped opening of the tube frame 6 always remains vertical and upward during the entire rotation of the rotating arm. This allows the tube frame to hold the processed cast pipe at the first processing station and move it to the second processing station under the drive of the rotating arm, thereby realizing the transfer and movement of the cast pipe between two adjacent stations. The device described in this application is simple and easy to maintain; it can achieve automatic transfer, making it convenient and quick to move ductile iron pipes between workstations, saving time and effort.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
