Description

Technical Field

[0001] This utility model relates to the field of roller auxiliary replacement technology, and in particular to an online roller removal device for a steel strip production line. Background Technology

[0002] In the cold rolling line of electrical steel strip, the rollers are also very important components. During the rolling process, the rollers are in direct contact with the metal being rolled. Therefore, the rollers will gradually wear down during operation. When the rollers are worn to a certain extent, a roller changer is needed to replace them with new rollers so that the line can continue to work.

[0003] Currently, when changing rollers, the equipment must be stopped after one round of processing and production is completed before the rollers can be replaced, which affects processing and production efficiency and can easily cause more serious wear to already worn rollers. Utility Model Content

[0004] In view of the above problems, this utility model provides an online roller pulling device for steel strip production lines.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A roll-pulling device for a steel strip production line is provided, comprising two sets of support roll assemblies spaced apart along the steel strip conveying direction. Each support roll assembly includes a roll for supporting the bottom wall of the steel strip and a first drive assembly for driving the roll to move up and down in parallel. A roll-pulling assembly is provided on one side of each of the two sets of support roll assemblies. The roll-pulling assembly includes a first support frame, a sliding seat, and a connecting roller. The first support frame is slidably mounted on the ground along the steel strip conveying direction. The sliding seat is slidably mounted on the first support frame along the roller axial direction. A first lifting seat is vertically and vertically mounted on the sliding seat. The connecting roller is fixedly mounted on the first lifting seat. A second drive assembly for driving the sliding frame to move is provided on the first support frame. A third drive assembly for driving the first lifting seat to move up and down vertically is provided on the sliding seat. A connecting assembly for connecting and fixing the ends of the roll is provided on the connecting roller.

[0007] Furthermore, the support roller assembly includes a second support frame symmetrically arranged on both sides of the steel strip, a second lifting seat vertically and vertically arranged on the second support frame, the first drive assembly includes a first screw jack, the base of the first screw jack is fixedly arranged on the top of the second support frame, the screw of the first screw jack is connected to the second lifting seat, and a first motor for connecting to and driving the second lifting seat is arranged on the second support frame.

[0008] The second lifting seat is rotatably connected to a rotating sleeve via a bearing. The rotating sleeve has a through hole coaxially opened for the roller to pass through. A first bolt is threaded along its own radial direction on the rotating sleeve. Multiple first bolts are evenly spaced along the axial direction of the rotating sleeve. The first bolts abut against the outer wall of the roller to fix the roller inside the rotating sleeve.

[0009] Furthermore, the second drive assembly includes a chain, sprockets, and a rotary handle. A slide rail is provided on the first support frame, and a sliding seat is slidably disposed on the slide rail. Sprockets are rotatably disposed at both ends of the first support frame, and the chain is wound around the two sprockets. The sliding seat is fixedly connected to the chain, and the rotary handle is rotatably disposed on the first support frame. The rotary handle is drively connected to any one of the sprockets.

[0010] Furthermore, the third drive assembly includes a second screw jack, the base of which is fixedly mounted on the top of the second support frame, the screw of which is connected to the second lifting seat, and a second motor is mounted on the second support frame for connecting to and driving the second lifting seat.

[0011] Furthermore, a connecting groove for inserting a roller is provided at one end of the connecting roller near the support roller assembly. The connecting assembly includes a second bolt. A threaded hole is provided through the outer wall of the connecting roller. The second bolt is threaded into the threaded hole. After passing through the outer wall of the connecting roller, the second bolt can abut against the outer wall of the roller.

[0012] Furthermore, threaded holes are provided on the top and bottom outer walls of the connecting roller. A second bolt is connected to the top outer wall of the connecting roller, and a third bolt that can abut against the outer wall of the roller is threaded in the bottom threaded hole of the connecting roller. The third bolt is located on the side of the second bolt close to the support roller assembly.

[0013] Furthermore, a reinforcing frame is fixedly installed at the bottom of the outer wall of the connecting roller, and a support roller is rotatably installed on the reinforcing frame. The support roller is vertically rolled on the outer wall of the sliding seat.

[0014] The beneficial effects of this utility model are as follows: During the production and processing process, the height of two rollers in the two sets of support roller assemblies is adjusted so that one roller is higher than the other roller as a working roller used to support the steel strip. When it is necessary to replace the working and worn roller, the height of the rollers in the two sets of support roller assemblies is swapped, and the roller to be replaced is loosened. The operator pushes the first support frame and drives the first lifting seat to rise and fall vertically to adjust the position of the connecting roller to be aligned with the roller to be replaced. Then, the sliding seat is driven to approach the support roller assembly so that the end of the roller to be replaced is inserted into the connecting roller. By connecting and fixing the roller to the connecting roller, the sliding seat can be driven to move in the opposite direction to pull out the roller. This realizes the online removal and replacement of rollers without stopping the equipment, thus improving the roller replacement efficiency. Attached Figure Description

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This application discloses an online roller-pulling device for a steel strip production line, referring to... Figure 1 and Figure 2The system includes two sets of support roller assemblies 1 spaced apart along the conveying direction of the steel strip. Each support roller assembly 1 includes a roller 11 for supporting the bottom wall of the steel strip and a first drive assembly for driving the roller 11 to move up and down in parallel. The roller 11 is detachably mounted on the support roller assembly 1. Specifically, the support roller assembly 1 also includes second support frames 12 symmetrically arranged on both sides of the steel strip. Each second support frame 12 on both sides of the steel strip has a second lifting seat 13 vertically slidingly mounted. A rotating sleeve 15 is rotatably mounted on the second lifting seat 13 via a bearing. The rotating sleeve 15 has a through hole coaxially through which the roller 11 passes. A first bolt 16 is threaded along its own radial direction on the rotating sleeve 15. Three first bolts 16 are spaced apart along the circumference of the rotating sleeve 15. The first bolts 16 can abut against the outer wall of the roller 11 after passing through the rotating sleeve 15. The first drive assembly can specifically be a first screw jack 14. The base of the first screw jack 14 is fixedly mounted on the top of the second support frame 12. The screw of the first screw jack 14 is connected to the second lifting seat 13. A first motor 17 is fixedly mounted on the top of the second support frame 12. The first motor 17 is connected to the base of the first screw jack 14, thereby driving the first screw jack 14 to move vertically. The second lifting seats 13 on the second support frames 12 on both sides of the steel strip move synchronously, thereby driving the roller 11 to move up and down. Through the support roller assembly 1, the roller 11 can be positioned below the steel strip along the width direction of the steel strip. By adjusting the height of the two rollers 11, either roller 11 can be kept in a supporting state on the steel strip, thereby freeing the other roller 11 from the production line. This allows the roller 11 to be pulled out from the side and replaced online.

[0022] Reference Figure 3 and Figure 4 A roller-drawing assembly is provided on one side of the two sets of support roller assemblies 1. The roller-drawing assembly includes a first support frame 21, a sliding seat 22, and a connecting roller 23. A track is fixed on the ground on one side of the support roller assembly 1 along the steel belt conveying direction. Rollers are rotatably mounted on the bottom of the first support frame 21, and the first support frame 21 is slidably mounted on the track via the rollers. A slide rail 214 is provided on the first support frame 21 along the axial direction of the roller 11. The sliding seat 22 is slidably mounted on the slide rail 214. A mounting frame is integrally fixed on the sliding seat 22. A first lifting seat 24 is vertically and vertically mounted on the mounting frame. The connecting roller 23 is integrally fixed on the side wall of the first lifting seat 24 near the support roller assembly 1. A connecting groove 231 for accommodating the end of the roller 11 is provided at the end of the connecting roller 23 away from the first lifting seat 24 along the axial direction of the roller 11. The first support frame 21 is provided with a second drive assembly for driving the sliding frame to move, the sliding seat 22 is provided with a third drive assembly for driving the first lifting seat 24 to rise and fall vertically, and the connecting roller 23 is provided with a connecting assembly for connecting and fixing the ends of the roller 11.

[0023] In this embodiment, the second drive assembly consists of a chain 211, sprockets 212, and a rotary handle 213. Two sprockets 212 are provided, spaced apart at both ends of the first support frame 21 along the axial direction of the roller 11. The chain 211 is wound around the two sprockets 212 and engages with them. A sliding seat 22 is fixedly connected to several chain links on the upper layer of the chain 211. The rotary handle 213 is rotatably mounted on the first support frame 21 and is drively connected to any one of the sprockets 212. By manually rotating the rotary handle 213, the chain 211 rotates with the sprockets 212, thereby dragging the sliding seat 22 to slide on the first support frame 21. Specifically, the rotating shaft of the sprocket 212 furthest from the support roller assembly 1 is connected to a worm gear reversing box. The rotary handle 213 is detachably connected to another input end of the reversing box, allowing the operator to easily remove the rotary handle 213 to avoid obstructing their movement.

[0024] In this embodiment, the third drive component may be a second screw jack 221. The base of the second screw jack 221 is fixedly mounted on the top of the first support frame 21. The screw of the second screw jack 221 is connected to the first lifting seat 24. A second motor 222 is fixedly mounted on the top of the first support frame 21 by bolts. The output shaft of the second motor 222 is connected to the base of the second screw jack 221. The first lifting seat 24 is driven to rise and fall by the second motor 222.

[0025] In this embodiment, the connecting assembly includes a second bolt 232. A threaded hole is provided through the outer wall of the connecting roller 23, and the second bolt 232 is threaded into the threaded hole. After passing through the outer wall of the connecting roller 23, the second bolt 232 can abut against the outer wall of the roller 11. After aligning the connecting roller 23 with the roller 11 and moving it to insert the end of the roller 11 into the connecting groove 231, the operator tightens the second bolt 232 to press it against the outer wall of the roller 11, thereby fixing the roller 11 and the connecting roller 23.

[0026] Furthermore, to better align the connecting roller 23 with the roller 11 in the horizontal direction, a tapered guide surface can be provided at the opening of the connecting groove 231. To prevent the end of the roller 11 away from the connecting roller 23 from naturally drooping after being connected to the connecting roller 23, thus causing the roller 11 to slip out of the connecting roller 23, in this embodiment, threaded holes are provided on both the top and bottom outer walls of the connecting roller 23. A second bolt 232 is connected to the top outer wall of the connecting roller 23, and a third bolt 233, capable of abutting against the outer wall of the roller 11, is threaded into the bottom threaded hole of the connecting roller 23. The third bolt 233 is located on the side of the second bolt 232 closest to the support roller assembly 1. By using the second bolt 232 and the third bolt 233 to abut against the roller 11 in a staggered and spaced manner, and by designing the size of the connecting groove 231 to be slightly larger than the size of the roller 11, the roller 11 inside the connecting roller cylinder 23 can be tilted upward toward the opening of the connecting groove 231 after the second bolt 232 and the third bolt 233 are tightened against the roller 11. This can effectively prevent the roller 11 inside the connecting roller cylinder 23 from tilting downward or even slipping out of the connecting roller cylinder 23 due to the natural drooping of the suspended end of the roller 11, thereby improving the support effect of the connecting roller cylinder 23 on the roller 11.

[0027] To further improve the connection reliability between the connecting roller 23 and the first lifting seat 24, in this embodiment, a reinforcing frame 234 is welded and fixed to the bottom of the outer wall of the connecting roller 23. A support roller 235 is rotatably mounted on the reinforcing frame 234, and the support roller 235 is vertically rolled on the outer wall of the sliding seat 22. The reinforcing frame 234 and the support roller 235 are obliquely supported on the vertical side wall of the mounting frame on the sliding seat 22, thus forming a triangular support structure below the connecting roller 23, which effectively supports the connecting roller 23 and the roller 11. The direct rolling connection between the support roller 235 and the vertical side wall of the mounting frame on the sliding seat 22 allows the first lifting seat 24 to smoothly rise and fall on the moving seat.
