[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a seamless steel pipe drawing device with a double support structure: it includes a machine platform 1, a drawing device assembly 2 installed on the top of the machine platform 1, support columns 3 installed around the bottom of the machine platform 1, support frames 4 installed on the top of the inner side of the support columns 3 and on both sides of the bottom of the machine platform 1, a drive assembly 5 is provided in the inner cavity of the support frame 4, the drive assembly 5 includes a drive motor 6 and a moving plate 7, a threaded rod 8 is installed at the output end of the drive motor 6, the bottom of the threaded rod 8 penetrates the bottom of the moving plate 7, a moving rod 9 is installed on the front and rear sides of the bottom of the moving plate 7, the bottom of the moving rod 9 penetrates the front and rear sides of the bottom of the support frame 4, a mounting groove 10 is formed at the bottom of the moving rod 9, a traveling wheel 11 is movably connected to the inner cavity of the mounting groove 10 through a movable shaft, and a telescopic rod 12 is installed on the front and rear sides of the top of the moving plate 7, the top of the telescopic rod 12 is fixed to the front and rear sides of the top of the inner cavity of the support frame 4.

[0021] Furthermore, the top of the movable plate 7 is provided with a threaded hole that cooperates with the threaded rod 8. The drive motor 6 drives the threaded rod 8 to rotate, and the rotational motion of the threaded rod 8 is converted into linear motion through the threaded hole.

[0022] Furthermore, the front and rear sides of the bottom of the inner cavity of the support frame 4 are provided with through holes 13 for use with the moving rod 9. The moving rod 9 moves linearly within the through holes 13 to ensure that the verticality of the moving rod 9 is ≤0.02mm / m.

[0023] Furthermore, a bearing housing is fitted to the bottom of the threaded rod 8, and the bottom of the bearing housing is fixed to the bottom of the inner cavity of the support frame 4. The bearing housing adopts a flange design, and the bottom is rigidly connected to the bottom of the inner cavity of the support frame 4 by 8.8 grade high strength bolts. When the drive motor 6 drives the threaded rod 8 to rotate, the bearing in the bearing housing bears the load, which is transmitted to the support frame 4 through the bearing raceway and absorbed by the anti-deformation structure of the bearing housing side wall.

[0024] Furthermore, an inspection door panel 14 is installed on the right side of the support frame 4 by screws. The inspection door panel 14 improves the convenience of maintenance while ensuring the rigidity of the equipment.

[0025] Furthermore, a base pad is installed at the bottom of the support column 3, and the base pad is made of rubber. Crossbeams are installed on the inner side of the support column 3 and on both sides of the bottom of the equipment platform 1. The crossbeams connect the support columns 3 to each other to form a closed triangular frame structure. When the support column 3 is subjected to lateral force, the crossbeams limit the radial displacement of the support column 3 through their axial stiffness, which can effectively decompose external forces in different directions.

[0026] It should be noted that this utility model is a seamless steel pipe drawing device with a double support structure. The drive motor 6 is started by the external controller. The drive motor 6 drives the threaded rod 8 to rotate. The threaded rod 8 cooperates with the threaded hole to push the moving plate 7 to move vertically. The moving plate 7 drives the walking wheel 11 to contact the ground through the moving rod 9 to form a secondary support point, lifting the equipment platform 1 and the support column 3. The equipment can be moved. The walking wheel 11 drives the equipment to move with an efficiency of 60%, which can meet the needs of multi-station flexible production lines. The four support columns 3 and the equipment platform 1 form a basic frame, which can effectively support the equipment platform 1. After moving to the designated area, the walking wheel 11 can be retrieved and lifted by the above reverse operation. The base pad and the support column 3 are in contact with the ground, which can effectively support and stabilize the equipment platform 1.
