[0016] In the figure, 1 is a steel pipe, 2 is a flange, 3 is a web, 31 is a first support ring, 32 is a second support ring, 4 is a roll body steel pipe, 5 is a stopper, 6 is an exhaust hole, 7 is a bearing seat, and 8 is a fixing bolt. DETAILED DESCRIPTION

[0017] The utility model will be explained in detail below in combination with the drawings and specific embodiments.

[0018] The portable roll device for the trial run of the rolling mill has the advantages that: Figure 1 As shown in the figure, it comprises a steel pipe 1, the outer wall of the middle part of the steel pipe 1 is sleeved with a web 3, the stability and strength of the overall structure are increased by arranging the web 3, and the local instability or bending of the structure under stress is prevented. Meanwhile, the web 3 can effectively transfer and disperse the load, improve the shearing performance and torsional stiffness of the structure, and thus enhance the durability and reliability of the structure, the outer wall of the web 3 is sleeved with a roll body steel pipe 4, the roll body steel pipe 4 is used to replace the existing roll body, the mass is small, and the device is portable, the two ends of the steel pipe 1 are fixedly connected with flanges 2, and the device further comprises two bearing seats 7, the two flanges 2 and the two bearing seats 7 are fixedly connected in one-to-one correspondence.

[0019] The two flanges 2 are welded on the two ends of the steel pipe 1, which saves materials and is conducive to ensuring the strength and rigidity of the roll body steel pipe 4.

[0020] Both flanges 2 are connected to the two bearing seats 7 through fixing bolts 8, which provide a detachable mechanical connection method, facilitating quick disassembly and reinstallation during equipment inspection, maintenance or adjustment. The fixing bolts 8 tightly fix the flanges and bearing seats together through threaded connection, ensuring the reliability and sealing of the connection, while allowing the bolts to be easily loosened for disassembly when needed. This connection method not only facilitates the adjustment of the installation gap of the equipment, but also can withstand axial force, radial force and torque during equipment operation, ensuring the stability and durability of the structure;

[0021] The roll body steel pipe 4 is welded to the outer wall of the web 3. The roll body steel pipe 4 is made of steel pipe or processed from steel plate after rolling. A firm mechanical connection is formed by welding to enhance the integrity and carrying capacity of the structure. The roll body steel pipe 4 can be directly processed from steel pipe or processed from steel plate after rolling. Both methods can provide high strength and rigidity. The roll body made of steel pipe has the characteristics of high forming precision and simple processing, while the steel plate rolling provides greater design flexibility, allowing the size and shape to be adjusted as needed. The welded connection not only ensures the stable combination of the roll body steel pipe and the web, but also effectively transfers axial force, bending moment and shear force to resist structural deformation. In addition, this design can adapt to complex working conditions, providing reliable support and stability to ensure the reliability and durability of the equipment during long-term operation;

[0022] The web 3 is provided with exhaust holes 6, which are arranged in parallel with the steel pipe 1. The exhaust holes 6 are pre-processed for stress relief during heat treatment of the roll body steel pipe 4 and for exhaust during processing, avoiding excessive internal cavity sealing pressure during processing, which may cause deformation of the workpiece and affect precision;

[0023] The web 3 includes a first support ring 31 and a second support ring 32. The first support ring 31 and the second support ring 32 are both sleeved on the outer wall of the steel pipe 1 and arranged in parallel. The first support ring 31 and the second support ring 32 are both welded to the steel pipe 1. The roll body steel pipe 4 is sleeved on the outer wall of the first support ring 31 and the second support ring 32 and is welded to the first support ring 31 and the second support ring 32. The first support ring 31 and the second support ring 32 are symmetrically arranged about the center line axis of the roll body steel pipe 4. The exhaust holes 6 are arranged on the second support ring 32, and the first support ring 31 and the second support ring 32 ensure that the roll body steel pipe 4 is stably arranged on the outer wall of the steel pipe 1;

[0024] Both flanges 2 are step-shaped disc structures, and both flanges 2 include a stopper 5. The end face distance of the stopper 5 of the flanges 2 at both ends is processed according to the end face distance of the existing bearing seats at both ends. The distance between the two stoppers 5 is 1500-2000mm. The diameter of the stopper 5 at both ends is processed according to the size of the corresponding part of the existing end cover.

[0025] The outer circle diameter of the roll body steel pipe is processed according to the existing roll body size, the outer diameter of the roll body steel pipe 4 is 300-1050mm, and the length of the roll body steel pipe 4 is 450-550mm, so that the detection needs of the rolling mill during commissioning can be met.

[0026] The working principle of the portable roll device for commissioning the rolling mill is that the steel pipe 1 is connected together with the two end bearing seats 7 through the joint 5 and the end face of the steel pipe 1, and the two are combined by the fixing bolt 8. Since the distance between the two end faces of the joint 5 is processed according to the distance between the end faces of the two end bearing seats 7, the distance between the two end bearing seats 7 is the same as the distance during assembly of the roll, and the outer circle of the roll body steel pipe 4 is used to replace the existing roll body outer circle to perform size inspection with the rack and other parts. Figure 1 The bearing seat assembly part after the roll body steel pipe 4 replaces the existing roll is used to perform commissioning test of the rolling mill such as roll replacement.
