Description

Technical Field

[0001] This utility model relates to the field of roller frame equipment technology, specifically a roller frame moving device. Background Technology

[0002] A roller frame moving device is a device used to assist in the movement and rotation of large cylindrical workpieces. The rollers are one of the most critical components of the roller frame, and are usually made of high-strength alloy steel or wear-resistant materials to ensure that they can withstand the weight of large workpieces and be used for a long time. The bracket is the supporting structure of the roller frame, which needs to have sufficient strength and stability. It is usually made of welded steel sections, such as I-beams and channel steel.

[0003] Mainly used in welding, machining and assembly, roller frame mobile equipment is a device where the motor drives the active roller to rotate, and due to the friction, the active roller will drive the workpiece to rotate together. The magnitude of the friction between the workpiece and the roller depends on factors such as the surface roughness of the roller, the weight of the workpiece, and the normal pressure between them. For example, in welding operations, by controlling the rotation speed of the roller, the cylindrical workpiece can be rotated at a uniform speed, which makes it convenient for the welder to perform circumferential welding on the workpiece.

[0004] In existing methods of using small roller frame moving devices to weld materials, one end of the roller moves to the other end to position the two ends of the material, and then the material is rotated by rotating the roller. However, most materials are round, and the top of the material does not have good positioning support, which makes the material unstable during rotation. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a roller frame moving device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roller frame moving device, including a base, a roller assembly mounted on the top of the base, a limiting plate mounted on the bottom of the roller assembly, an electric push rod mounted on one end of the limiting plate, and teeth provided on the lower end of the limiting plate. A second gear is provided on the outer wall of the teeth, and a first gear is provided on the coaxial axis of the second gear. A rack is provided on the outer wall of the first gear, and a connecting rod is provided on the top of the rack. A positioning wheel is mounted on one end of the connecting rod.

[0007] By adopting the above technical solution, the positioning wheel is positioned by setting the connecting rod, so that the positioning wheel moves with the roller assembly and clamps the outer wall of the round material synchronously, which improves the stability of the material placed on the equipment. Moreover, the roller is triangular and located on the outer wall of the material, which improves the quality of material processing and welding. By setting the limiting plate, the limiting plate is connected to the bottom of the roller assembly. When the roller assembly is moved, the limiting plate moves synchronously, which drives the connecting rod to descend. This reduces the cost of the equipment and improves the stability and working efficiency of the equipment.

[0008] The present invention is further configured such that a support frame is installed on the top of the positioning wheel, and hydraulic rods are installed at both ends of the support frame.

[0009] By adopting the above technical solution, the support frame and hydraulic rod effectively support and position the positioning wheel, thereby effectively improving the stability of the positioning wheel during movement.

[0010] The present invention is further configured such that the bottom of the hydraulic rod is connected to the base, and the hydraulic rod is an adjustable hydraulic rod.

[0011] By adopting the above technical solution, the adjustable hydraulic rod is a device that can change its length and supporting force through adjustment. It mainly consists of a hydraulic cylinder, piston rod, sealing device, oil inlet and outlet, etc. By changing the pressure of hydraulic oil, the piston rod can be extended and retracted, thereby achieving the purpose of adjusting the length and supporting force.

[0012] The present invention is further configured such that there are two sets of roller assemblies, the two sets of roller assemblies are arranged opposite to each other, and one set of roller assemblies is connected to the limiting plate.

[0013] By adopting the above technical solution, a limiting plate is installed at the bottom of the roller assembly, and an electric push rod is installed at one end of the limiting plate. The electric push rod pushes the roller assembly to move while the positioning wheel moves downward synchronously.

[0014] The present invention is further configured such that the positioning wheel and the two sets of roller assemblies are triangular in shape, and one set of roller assemblies is fixedly connected to the base.

[0015] By adopting the above technical solution, the outer wall of the circular material is clamped simultaneously, which improves the stability of the material when placed on the equipment. Furthermore, the rollers are triangular in shape and located on the outer wall of the material, thereby improving the quality of material processing and welding.

[0016] The present invention is further configured such that a connecting rod is installed on the outer wall of the positioning wheel, and a rack is installed at the bottom of the connecting rod, and the connecting rod is L-shaped.

[0017] By adopting the above technical solution, the limiting plate moves synchronously, thereby driving the connecting rod to descend, which reduces the cost of the equipment and improves the stability and working efficiency of the equipment.

[0018] The present invention is further provided that the inner wall of the base is provided with a sliding groove, and the lower end of the sliding groove is provided with a limiting plate.

[0019] By adopting the above technical solution, the roller assembly and the limiting plate are connected through the slide groove, and the electric push rod drives the roller assembly to move while simultaneously driving the limiting plate to move.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention uses a connecting rod to position the positioning wheel, allowing it to move along with the roller assembly and simultaneously clamp the outer wall of the circular material. This improves the stability of the material when placed on the equipment. Furthermore, the triangular shape of the roller on the outer wall of the material enhances the quality of material processing and welding.

[0022] This invention uses a limiting plate that is connected to the bottom of the roller assembly. When the roller assembly is moved, the limiting plate moves synchronously, thereby driving the connecting rod to descend. This reduces the cost of the equipment and improves its stability and working efficiency. Attached Figure Description

A second gear 16 is provided on the outer wall of the tooth 21, and a first gear 15 is provided on the coaxial axis of the second gear 16. A rack 14 is provided on the outer wall of the first gear 15, and a connecting rod 13 is provided on the top of the rack 14. A positioning wheel 3 is mounted on one end of the connecting rod 13. The positioning wheel 3 is positioned by the connecting rod 13. Positioning is achieved by positioning the roller 3 so that it moves along with the roller assembly 2, simultaneously clamping the outer wall of the circular material, thus improving the stability of the material placed on the equipment. The rollers are triangular and located on the outer wall of the material, thereby improving the quality of material processing and welding. Through the setting of the limiting plate 20, which is connected to the bottom of the roller assembly 2, the limiting plate 20 moves synchronously when the roller assembly 2 is moved, thereby driving the connecting rod 13 to descend, reducing the cost of the equipment and improving its stability and working efficiency.

[0031] Please see Figure 1 - Figure 3 A support frame 12 is installed on the top of the positioning wheel 3, and hydraulic rods 11 are installed at both ends of the support frame 12. The support frame 12 and hydraulic rods 11 effectively support and position the positioning wheel 3, thereby effectively improving the stability of the positioning wheel 3 during movement.

[0032] Please see Figure 1 - Figure 3 The bottom of the hydraulic rod 11 is connected to the base 1, and the hydraulic rod 11 is an adjustable hydraulic rod. An adjustable hydraulic rod is a device that can change its length and support force by adjustment. It mainly consists of a hydraulic cylinder, piston rod, sealing device, oil inlet and outlet, etc. By changing the pressure of hydraulic oil, the piston rod can move to extend or retract, thereby achieving the purpose of adjusting the length and support force.

[0033] Please see Figure 1 - Figure 3 There are two sets of roller assemblies 2, and the two sets of roller assemblies 2 are arranged opposite to each other. One set of roller assemblies 2 is connected to the limiting plate 20. The limiting plate 20 is installed at the bottom of the roller assembly 2, and an electric push rod is installed at one end of the limiting plate 20. The electric push rod pushes the roller assembly 2 to move while the positioning wheel 3 moves downward synchronously.

[0034] Please see Figure 1 - Figure 3The positioning wheel 3 and the two sets of roller assemblies 2 are triangular in shape, and one set of roller assemblies 2 is fixedly connected to the base 1. They simultaneously clamp the outer wall of the circular material, which improves the stability of the material placed on the equipment. The triangular shape of the rollers on the outer wall of the material further improves the quality of material processing and welding.

[0035] Please see Figure 3 , Figure 4 The outer wall of the positioning wheel 3 is equipped with a connecting rod 13, and the bottom of the connecting rod 13 is equipped with a rack 14. The connecting rod 13 is L-shaped. The limiting plate 20 moves synchronously, thereby driving the connecting rod 13 to descend, which reduces the cost of the equipment and improves the stability and working efficiency of the equipment.

[0036] Please see Figure 1 - Figure 3 The inner wall of the base 1 is provided with a sliding groove 10, and the lower end of the sliding groove 10 is provided with a limiting plate 20. The roller assembly 2 and the limiting plate 20 are connected through the sliding groove 10. The electric push rod drives the roller assembly 2 to move while driving the limiting plate 20 to move.

[0037] The working principle of this utility model is as follows:

[0038] When a round material needs to be placed on the equipment for processing, the material is first placed on the top of the base 1. Then, the control button is activated to move the electric push rod to move the roller assembly 2, so that the roller assembly 2 fits against the outer wall of the material. At the same time, the movement of the roller assembly 2 moves the limiting plate 20, which causes the teeth 21 on the outer wall of the limiting plate 20 to drive the second gear 16 to rotate, which in turn causes the first gear 15 to drive the rack 14 to rotate, thereby causing the connecting rod 13 to move down and the positioning wheel 3 to move down. This multi-angle positioning of the outer wall of the round material improves the stability of the material on the equipment, thereby improving the quality of the welded material.
