Description
Technical Field
[0001] The utility model relates to the technical field of mobile roller frames, in particular to a large-tonnage mobile roller frame. Background Art
[0002] Mobile roller racks are usually used to support and move long pipes, especially during welding. Mobile roller racks can help support the weight of the pipe and keep the pipe stable during welding. The roller racks are designed to bear the weight of the pipe and prevent it from sagging or deforming during welding. The rollers equipped on the mobile roller racks enable the pipe to move freely in the workplace.
[0003] Large-tonnage roller frames can effectively support and move heavy pipes. When placing pipes on mobile roller frames, the pipes need to be placed between two sets of rollers so that the mobile roller frames can support the pipes and keep them stable during welding. Since mobile roller frames generally only adjust the spacing between the two sets of rollers, when welding pipes of different diameters, the staff needs to adjust the height of the welding equipment accordingly. Therefore, we proposed a large-tonnage mobile roller frame. Utility Model Content

[0020] In specific implementation, according to Figures 1 - 3 , the large-tonnage roller rack can effectively support and move heavy pipelines. When the mobile roller rack arranges the pipeline, the pipeline needs to be placed in the middle of two groups of rollers, so that the mobile roller rack supports the pipeline and keeps the pipeline stable during the welding process. When the mobile roller rack arranges a pipeline with a larger diameter, start the double-headed motor 201, and let the output end of the double-headed motor 201 drive the second gear disk 106 and the first bevel gear 2 to rotate. Through the meshing connection of the first gear disk 105 and the second gear disk 106, the second gear disk 106 drives the first gear disk 105 to rotate, so that the first gear disk 105 drives the first roller plate 104 to rotate and unfold.

Through the meshing connection of the first bevel gear 2 and the second bevel gear 202, the first bevel gear 2 drives the second bevel gear 202 to rotate, so that the second bevel gear 202 drives the screw rod 102 to rotate. Through the threaded connection of the branch pipe 101 and the screw rod 102, and the thread directions of the two screw rods 102 are opposite, the screw rod 102 can move down along the branch pipe 101. At this time, the screw rod 102 pushes the slide plate 204 to slide along the chute 203, and the chute 203 can indicate the measuring scale 205, so that the staff can control the distance of the screw rod 102 moving down by checking the measuring scale 205, making it convenient for the mobile roller rack to arrange pipelines with larger diameters, and can control the pipeline to move down at the same time, enabling the large-tonnage mobile roller rack to be adjusted in height when welding pipelines with different diameters.
[0021] To sum up, the large-tonnage roller rack can effectively support and move heavy pipelines. When the mobile roller rack arranges the pipeline, the pipeline needs to be placed in the middle of two groups of rollers, so that the mobile roller rack supports the pipeline and keeps the pipeline stable during the welding process. When the mobile roller rack arranges a pipeline with a larger diameter, start the double-headed motor 201, and let the output end of the double-headed motor 201 drive the second gear disk 106 and the first bevel gear 2 to rotate, so that the first gear disk 105 drives the first roller plate 104 to rotate and unfold. At the same time, the first bevel gear 2 rotates, so that the screw rod 102 can move down along the branch pipe 101. At the same time, the staff can control the distance of the screw rod 102 moving down by checking the measuring scale 205, making it convenient for the mobile roller rack to arrange pipelines with larger diameters, and can control the pipeline to move down at the same time, enabling the large-tonnage mobile roller rack to be adjusted in height when welding pipelines with different diameters.
