Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a rolling mill protection device. Background Technology

[0002] Rolls are the main components of a rolling mill. They are a pair of rolls rotating in opposite directions, with a slit or hole of a specific shape between them. Steel billets pass through the slit or hole and are rolled into steel. They are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. A rolling mill 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, and it has a smooth cylindrical or grooved surface.

[0003] After the rolls are manufactured and processed, they are simply wrapped and protected before being transported to the user's site by truck or train. Due to the special roll shape, irregular shape, and multiple slots of some rolls, unstable road conditions and bumpy rides during transportation often cause the rolls to roll, creating safety hazards. In severe cases, the edges of the slots may rub against the rolls, resulting in edge damage or chipping, causing quality problems, affecting product use at the user's site, and causing serious losses. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3A roll protection device includes a base 1, a sliding cavity 2 inside the base 1, a bidirectional threaded rod 3 rotatably connected inside the sliding cavity 2, a turntable 4 fixedly connected to the front end of the bidirectional threaded rod 3, two mutually symmetrical clamping mechanisms threadedly connected to the bidirectional threaded rod 3, a plurality of sliding grooves 5 on the upper surface of the base 1, a limit mechanism fixedly connected inside the sliding grooves 5, a fixed seat at the front end of the base 1, and a connecting seat fixedly connected to the end of the base 1, the fixed seat and the connecting seat being connected by a fixing component.

[0021] like Figures 1 to 3 As shown, the roll protection device of this utility model can be used in a number that can be selected according to the length of the roll. Simply connect the connecting seat on one device to the fixing seat on another device and secure them with a fixing assembly. Then rotate the turntable 4, causing the bidirectional threaded rod 3 to rotate, which in turn causes the two U-shaped sliding plates 6 to move in opposite directions, thereby pushing the limiting rod 7 outwards to adjust the distance between the two limiting rods 7. Finally, place the roll on the base 1. Because the base 1... The upper surface is arc-shaped, which can fix the position of the roll and prevent the roll from shaking. At the same time, the slide bar 11 located below the roll moves downward under pressure, so as not to affect the placement of the roll. The slide bars 11 located on the front and rear sides of the roll are not under pressure, so under the action of the spring 10, they are always above the upper surface of the base 1, thus restricting the front and rear ends of the roll and preventing it from slipping in front of and behind the base 1. Then, the turntable 4 is rotated in the opposite direction, so that the two limit bars 7 move inward to clamp and restrict the roll, further preventing the roll from shaking.

[0022] like Figure 1 As shown, the upper surface of the base 1 is arc-shaped, and an anti-slip and wear-resistant pad 16 is fixedly connected to its upper surface.

[0023] Specifically, the upper surface of the base 1 is arc-shaped, which can be used to place rolls of different sizes, support a pair of rolls, and restrict the rolling of the rolls. The anti-slip and wear-resistant pad 16 can protect the base 1 and increase the friction between the rolls and the base 1, thereby further preventing the rolls from shaking and sliding.

[0024] like Figure 2 As shown, the clamping mechanism includes a U-shaped slide plate 6 threadedly connected to a bidirectional threaded rod 3, the U-shaped slide plate 6 being slidably connected to the base 1, and two limiting rods 7 being fixedly connected to the front end of the U-shaped slide plate 6.

[0025] Specifically, rotating the turntable 4 causes the bidirectional threaded rod 3 to rotate, which in turn causes the two U-shaped slide plates 6 to move in opposite directions, thereby pushing the limiting rod 7 to move outward so as to adjust the distance between the two limiting rods 7, thus facilitating the placement of the roll on the base 1. Then, rotating the turntable 4 in the opposite direction causes the two limiting rods 7 to move inward so as to clamp and restrict the roll, further preventing the roll from shaking.

[0026] like Figure 2 As shown, the lower ends of the two limiting rods 7 are rotatably connected to a rotating shaft 8, and both ends of the rotating shaft 8 are fixedly connected to rollers 9.

[0027] Specifically, the rollers 9 can support the limiting rod 7, and can also support the limiting rod 7 on both sides of the base 1, so that the device and the rollers are more stable when they are shaken or bumped.

[0028] like Figure 3 As shown, the limiting mechanism includes a spring 10 fixedly connected inside the slide groove 5, and a slide rod 11 fixedly connected to the upper end of the spring 10.

[0029] Specifically, the roll is placed on the base 1. Since the upper surface of the base 1 is arc-shaped, the position of the roll can be fixed to prevent the roll from shaking. At the same time, the slide bar 11 located below the roll is pressured and moves downward, so as not to affect the placement of the roll. The slide bars 11 located on the front and rear sides of the roll are not pressured, so under the action of the spring 10, they are always above the upper surface of the base 1. This can restrict the front and rear ends of the roll and prevent it from slipping off the base 1.

[0030] like Figure 1 As shown, the fixing base includes two grooves 12 at the front end of the base 1, and threaded holes 13 communicating with the grooves 12 are provided on both sides of the base 1.

[0031] Specifically, the groove 12 is used to place the connecting rod 14 on the connecting seat of another device, and the threaded hole 13 is used for threaded connection of the fixing component to fix and restrict the connecting seat.

[0032] like Figure 1 As shown, the connecting seat includes a connecting rod 14 fixedly connected to the rear end of the base 1, and the connecting rod 14 has a circular hole 15 corresponding to the threaded hole 13.

[0033] Specifically, the connecting rod 14 is inserted into the groove 12 on the mounting base of another device, and the fixing component is threadedly connected to the threaded hole 13 on the mounting base of another device. The front end of the fixing component is located inside the round hole 15, which can restrict and fix the round hole 15.

[0034] like Figure 2 As shown, the fixing component includes a hexagonal bolt 17 threaded onto a threaded hole 13, and a plug 18 is fixedly connected to the front end of the hexagonal bolt 17.

[0035] Specifically, the hex bolt 17 is threaded into the threaded hole 13. The insertion rod 18 at the front end of the hex bolt 17 is located inside the round hole 15 on the connecting rod 14. The insertion rod 18 can restrict the forward and backward movement of the connecting rod 14. Combined with the function of the groove 12, the connecting rod 14 can be fixed, thereby connecting the two devices. The number of devices used can be selected according to the length of the roll.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
