Description

Technical Field

[0001] This utility model relates to the field of aluminum coil processing technology, and more specifically, to a buffer limiting device for a coil transport trolley. Background Technology

[0002] Aluminum coils are metal products produced by casting and rolling mills through rolling, bending, and angle processing, and are then ready for flying shearing. They are widely used in electronics, packaging, construction, machinery, and other fields. During the aluminum coil processing, the aluminum sheets produced by the casting and rolling mill are rolled into aluminum coils and then transported to the next processing stage using a coil transport trolley. To ensure the safety of aluminum coil transportation, buffer limit devices are often required on the coil transport trolley.

[0003] The prior art discloses an aluminum coil processing and feeding device with publication number CN218260394U, including a guide rail, a mobile trolley mounted on the guide rail, a power mechanism mounted at one end of the mobile trolley for driving the mobile trolley to move along the guide rail, a hydraulic cylinder mounted on the top of the mobile trolley, and a material support frame mounted on the top of the hydraulic cylinder; the upper surface of the material support frame is recessed with a V-shaped material support groove, and the upper surface of the material support frame is provided with a buffer layer; by designing the material support groove as V-shaped, it can limit the movement of aluminum coils of various sizes, stably placing the aluminum coils inside the material support groove, which has a wide range of applications, and can also play a buffering and shock-absorbing role between the aluminum coil and the material support frame through the buffer layer, avoiding rigid contact between the aluminum coil and the material support frame, thereby avoiding damage to the aluminum coil from impacts.

[0004] The aforementioned utility model utilizes a V-shaped material tray on the material tray to limit the movement of the aluminum coil on both sides during transport. Then, a rubber buffer layer fixedly installed on the inner wall of the material tray provides cushioning and protection for the aluminum coil during transport. Although this structure can provide some limiting and buffering protection for the aluminum coil, its limiting and fixing effect is poor. The aluminum coil is still prone to slipping or jumping during transport, which poses a threat to the reliability and safety of aluminum coil transport. Its practicality is relatively limited.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a buffer limiting device for a winding trolley, which has the following advantages:

[0017] (1) This utility model is equipped with a material support frame, a side limiting plate, and an arc-shaped top plate. Hydraulic cylinders are installed at the four corners of the top surface of the trolley body, and the output ends of the hydraulic cylinders are connected to the material support frame. Several material support grooves are evenly distributed on the material support frame, and an installation groove is formed in the center of the bottom surface of each material support groove. A bidirectional lead screw is installed in the installation groove, and installation sliders are symmetrically embedded in the installation groove. A first lead screw sleeve is fixedly installed in the installation slider, and a bidirectional lead screw is threaded into the first lead screw sleeve. In use, […]. The aluminum coil is moved into the center of the support groove. At this point, the two sides of the aluminum coil abut against the inner wall of the V-shaped support groove, achieving the limitation of the aluminum coil on both sides. Then, the worker can start the servo motor installed on one side of the support frame through the control panel. The output end of the servo motor is connected to one end of the adjustment shaft installed in the mounting cavity. Several first bevel gears are evenly fixedly installed on the adjustment shaft. Several bidirectional lead screws are located in the inner cavity of the mounting cavity and have second bevel gears fixedly installed at one end. The second bevel gears mesh with the first bevel gears. Therefore, when the adjustment shaft... When the shaft drives several first bevel gears to rotate, it can simultaneously drive several double-acting screws to rotate. When the double-acting screws rotate, they can drive two mounting sliders to move relative to each other. The top of the mounting sliders is fixedly installed with side limiting plates, so the two side limiting plates can move relative to each other with the mounting sliders until the two side limiting plates limit and fix the two ends of the aluminum coil. Finally, the worker can adjust the hand crank to drive the limiting screw, which is fixedly installed on the top surface of the side limiting plate and is connected to the limiting screw. The bottom end of the limiting screw is connected to an arc-shaped pressure plate, and the top surface of the arc-shaped pressure plate is symmetrically fixedly installed with a guide slide rod, which is sleeved in the guide slide sleeve. When the arc-shaped pressure plate moves downward with the rotation of the limiting screw, it can press and limit the top surface of the aluminum coil. This can limit the sides, ends, and top surface of the transported aluminum coil, preventing the aluminum coil from sliding or jumping during transportation. This greatly improves the reliability and safety of the aluminum coil transportation process and can be applied to the transportation of aluminum coils of different sizes within a certain range. It has a wider range of applications and is more practical.

A bidirectional lead screw 13 is installed within the mounting groove 14, and mounting sliders 22 are symmetrically fitted within the mounting groove 14. A first lead screw sleeve 23 is fixedly installed within the mounting slider 22, and the bidirectional lead screw 13 is threaded into the first lead screw sleeve 23. In use, the aluminum coil is moved into the center of the material support groove 8.
