Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling mill frame technology, specifically a double-layer rolling mill frame. Background Technology
[0002] Rolls are the main working components and tools on a rolling mill that cause continuous plastic deformation of metal. A roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in the rolling of metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing and transmits the rolling force to the mill stand through the bearing housing and the pressing device. The drive end shaft end is connected to a gear housing via a connecting shaft, transmitting the rotational torque of the motor to the roll. Rolls can be arranged in two-roll, three-roll, four-roll, or multi-roll configurations within the rolling mill stand.
[0003] When storing rolling mill rolls, brackets are typically used to support both ends of the rolls for placement. Due to the large size of the rolls, they are usually placed from top to bottom using a hoisting method. However, existing brackets are usually single-layer structures, which cannot utilize the space above the bracket, resulting in low space utilization and a large footprint when there are many rolls. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a double-layer roll holder with a detachable structure. It can make full use of vertical space to store double-layer rolls, thereby improving space utilization, reducing the floor space occupied when storing rolls in batches, and is easy to use. It can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer roll frame, including a square tube frame base, with two symmetrical square tube supports at both ends of the square tube frame base and perpendicular to the square tube frame base. A channel steel beam is movably installed on the top of the square tube support, and polyurethane brackets are installed on the upper surface of the channel steel beam and the upper surface of the square tube frame base corresponding to the channel steel beam.
[0006] As a preferred technical solution of this utility model, the upper surface of the square tube frame base and the upper surface of the channel steel beam are provided with symmetrically arranged limiting channel steels, and the polyurethane bracket is movably engaged between the two symmetrical limiting channel steels.
[0007] As a preferred technical solution of this utility model, the bottom of the channel steel beam corresponding to the square tube support is provided with a limiting insert that can be inserted into the square tube support.
[0008] As a preferred technical solution of this utility model, the bottom of the limiting plate is chamfered, and the lower end of the limiting plate is inclined towards the middle of the limiting channel steel.
[0009] As a preferred embodiment of this utility model, the channel steel beam is snapped onto the square tube support with its opening facing downwards, and the lower end of the wing plate of the channel steel beam is inclined outwards.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The double-layer roll holder of this utility model adopts a detachable structure, which can make full use of vertical space to store double-layer rolls, thereby improving space utilization, reducing the floor space occupied when storing batch rolls, and making it convenient to use.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a double-layer roll frame, including a square tube frame base 1. Two symmetrical square tube supports 2 are provided at both ends of the square tube frame base 1 and are perpendicular to the square tube frame base 1. A channel steel beam 3 is movably installed on the top of the square tube support 2. A polyurethane bracket 5 is installed on the upper surface of the channel steel beam 3 and the upper surface of the square tube frame base 1 corresponding to the channel steel beam 3. First, the roll is placed on the polyurethane bracket 5 on the square tube frame base 1 to complete the placement of the lower roll. Then, the channel steel beam 3 is installed, and then the roll is placed on the polyurethane bracket 5 on the channel steel beam 3.
[0019] Furthermore, the upper surfaces of the square tube frame base 1 and the channel steel beam 3 are provided with symmetrically arranged limiting channel steels 4, and the polyurethane bracket 5 is movably engaged between the two symmetrical limiting channel steels 4 for engaging the polyurethane bracket 5.
[0020] Furthermore, the bottom of the channel steel beam 3 corresponding to the square tube support 2 is provided with a limiting plate 31 that can be inserted into the square tube support 2, so as to limit the channel steel beam 3 and prevent the channel steel beam 3 from moving on the square tube support 2.
[0021] Furthermore, the bottom of the limiting insert plate 31 is chamfered, and the lower end of the limiting insert plate 31 is inclined toward the middle of the limiting channel steel 4, so that the limiting insert plate 31 can be inserted into the square tube support 2.
[0022] Furthermore, the channel steel beam 3 is snapped onto the square tube support 2 with its opening facing downwards, and the lower end of the flange of the channel steel beam 3 is inclined outwards to facilitate snapping the channel steel beam 3 onto the square tube support 2.
