Description

Technical Field

[0001] This utility model relates to the field of metal rolling equipment technology, specifically to a guide support device. Background Technology

[0002] Guides are devices installed before and after the roll passes during the rolling process of steel profiles to help the rolled workpiece enter and exit the roll passes accurately and stably in a predetermined direction and state. In order to improve the stability of the guides, they need to be supported by support devices after installation to increase their stability and avoid the risk of equipment failure. The guides are assembled from a variety of components, including the main body, support arms, guide plates, guide wheels, and nose tips. These components are in different positions and are mostly connected by fasteners such as bolts.

[0003] According to patent document CN219357406U, this utility model discloses a guide support device, relating to the field of metal rolling technology. This utility model includes a connector, on which a plurality of support components for preventing guide displacement are connected. Each support component has a retractable support end and a reaction mechanism that senses movement of the support end and provides corresponding protective action. This utility model connects the plurality of support components via the connector, allowing the support components to abut against different components of the guide. This not only supports the guide as a whole but also each individual component, improving the support effect. Simultaneously, the reaction mechanism provides timely protective action when each component shifts, preventing damage to components on the guide and equipment malfunctions causing downtime. When the guide needs to be disassembled, one side of the guide is unfolded, facilitating its removal from the mill outlet or inlet, avoiding interference from the support equipment during disassembly.

[0004] Currently, guides in existing technologies are subjected to significant impact and friction during use, causing the guide wheels to wear out quickly and requiring replacement. Typically, replacing the guide wheels requires removing multiple fasteners before removing the guide wheels from the guide body, which is not only time-consuming and labor-intensive but also prone to causing other components to loosen or be damaged due to improper operation. This further increases maintenance costs and downtime. In addition, the installation and disassembly of guides in existing technologies often require specialized tools or complex operating procedures, increasing the difficulty of operation for workers.

Two symmetrical sliders 135 are threadedly connected to the outer wall of the bidirectional threaded rod 134. A clamping plate 136 is fixedly connected to the front side of the sliders 135. A fixing post 137 is fixedly connected to the side of the upper and lower clamping plates 136 that are close to each other. The outer wall of the upper and lower fixing posts 137 is movably connected to the inner wall of the guide wheel 14. A circular movable hole 2 extending to the outside is opened at the top of the inner wall of the upper mounting slot 133. A limit rod 138 is movably connected to the inner wall of the circular movable hole 2 in the upper mounting slot 133. The bottom of the limit rod 138 is fixedly connected to the top of the slider 135. The system is connected in a fixed manner. A worm gear 139 is fixedly connected to the outer wall of the limiting rod 138. A worm 130 is meshed with the outer wall of the worm gear 139. Support sleeves 1301 are movably connected to both sides of the outer wall of the worm 130. The bottom of the support sleeves 1301 is fixedly connected to the top of the fixing plate 131. A fixing rod 1302 is fixedly connected to the end of the two support sleeves 1301 that are close to each other. A support sleeve 1303 is movably connected to the outer wall of the fixing rod 1302. The bottom of the support sleeve 1303 is fixedly connected to the top of the upper fixing plate 132. A fixing plate 1304 is fixedly connected to the left end of the left worm 130. A rectangular slot 1305 is opened at the left end of the fixing plate 1304. A trapezoidal plate 1306 is fixedly connected to the rear side of the fixing plate 131.The outer wall of the trapezoidal plate 1306 is movably connected to the inner wall of the dovetail groove 128. A limiting groove is provided on the rear side of the trapezoidal plate 1306. The outer wall of the trapezoidal block 120 is movably connected to the inner wall of the limiting groove provided in the trapezoidal plate 1306. By inserting a torque wrench into the rectangular slot 1305 and rotating it, the fixed plate 1304 is driven to rotate. The rotation of the fixed plate 1304 drives the left worm gear 130 to rotate, which in turn drives the right worm gear 130 to rotate via the fixed rod 1302. Rotation of 130 drives the worm gear 139, causing the limit rod 138 to rotate. This, in turn, drives the two sliders 135 to move simultaneously inward and outward on the outer wall of the bidirectional threaded rod 134. This causes the upper and lower clamping plates 136 to move closer or further apart, adjusting the tightness between the fixing post 137 and the guide wheel 14. This allows for the disassembly of the guide wheel 14 and is compatible with various models of guide wheels 14. When disassembly of the guide wheel assembly 13 is required, pulling the handle 125 causes the two sliding rods 124 to engage with the double-hole fixing plate 134. The inner wall of 23 moves, thereby driving the limiting plate 127 to move and compressing the spring 126. When the limiting plate moves, the fixing block 129 and the trapezoidal block 120 move accordingly, causing them to slide on the inner wall of the rectangular movable hole opened in the dovetail groove 128 and disengage from the inner wall of the dovetail groove 128. At this time, the guide wheel assembly 13 can be removed from the support arm assembly 12 as a whole. When installing a new guide wheel assembly 13, simply align the trapezoidal plate 1306 with the dovetail groove 128, and then slide the trapezoidal plate 1306 along the dovetail groove. When the trapezoidal plate 1306 contacts the inclined surface of the trapezoidal block 120, it pushes the trapezoidal block 120 until it corresponds to the limiting groove opened in the dovetail groove 128. At this time, the rebound force of the spring 126 pushes the slide rod 124 to reset, thereby moving the limiting plate 127 and the fixing block 129, pushing the trapezoidal block 120 into the interior of the limiting groove opened in the dovetail groove 128, completing the fixed installation of the guide wheel assembly 13. The whole process is simple to operate and greatly improves the efficiency of maintenance and replacement.

The top of the limiting plate 1 205 is fixedly connected to the lead screw 207. The top of the lead screw 207 is rotatably connected to the inner wall of the mounting frame 21. The outer wall of the lead screw 207 is threadedly connected to the slider 208. The side of the two sliders 208 that are close to each other is fixedly connected to the fixing plate 4 209. The lower right side of the front right side of the fixing plate 4 209 is provided with the mounting groove 4 210. The top right side of the mounting groove 4 210 is provided with the mounting groove 5 211. The inner wall of the mounting groove 4 210 is fixedly connected to the step Stepper motor 212 has a gear 3 213 fixedly connected to its output end. The right end of gear 3 213 is rotatably connected to the inner wall of mounting groove 4 210. Gear 4 214 is meshed with the outer wall of gear 3 213.

The right end of gear 4 214 is rotatably connected to the inner wall of mounting groove 5 211. A mounting sleeve 216 is fixedly connected to the middle position of the inner wall of fixed plate 4 209. A bidirectional threaded rod 217 is movably connected to the inner wall of mounting sleeve 216.The left end of the bidirectional threaded rod 217 is rotatably connected to the inner wall of the fixing plate 209. Two symmetrical sliders 218 are threadedly connected to the outer wall of the bidirectional threaded rod 217. Anti-slip fixing plates 219 are fixedly connected to the top of the sliders 218. The side of the two anti-slip fixing plates 219 that is close to each other, the mounting sleeve 216, and the top of the fixing plate 209 are movably connected to the outer wall of the guide assembly 11. By starting the stepper motor 212, the gear 213 rotates, which in turn drives the gear 214 to rotate the limiting disk 215, thereby causing the bidirectional threaded rod 217 to rotate. This causes the two sliders 218 to move simultaneously inward and outward on the outer wall of the bidirectional threaded rod 217. Adjusting the tightness between the anti-slip fixing plate 219 and the guide assembly 11 enables quick clamping and releasing of the guide assembly 11. Starting the stepper motor 25 drives the rotating shaft 26 to rotate, which in turn drives the gear 28 to rotate. The meshing of gear 28 and gear 29 further drives the rotating rod 201 and the limiting rod 203 to rotate, causing the conical gear 204 to drive the conical gear 206 to rotate, thereby rotating the lead screw 207. The rotation of the lead screw 207 pushes the slider 208 to move up and down. The movement of the two sliders 208 adjusts the height of the fixing plate 209, adapting to the installation requirements of guide assemblies 11 of different sizes, significantly improving the applicability and ease of operation of the equipment.

[0021] Working principle: By inserting a torque wrench into the rectangular slot 1305 and rotating it, the fixed plate 1304 is rotated. The rotation of the fixed plate 1304 drives the left worm gear 130 to rotate, which in turn drives the right worm gear 130 to rotate via the fixed rod 1302. The rotation of the worm gear 130 drives the worm wheel 139, causing the limiting rod 138 to rotate. This causes the two sliders 135 to move inward and outward simultaneously on the outer wall of the bidirectional threaded rod 134, thereby moving the upper and lower clamping plates 136 closer or further apart to adjust the tightness between the fixed post 137 and the guide wheel 14. This allows for the disassembly of the guide wheel 14 and is compatible with various models of guide wheels 14. When it is necessary to disassemble the guide wheel assembly 13, pulling the handle 125 moves the two sliding rods 124 on the inner wall of the double-hole fixed plate 123, which in turn moves the limiting plate 127 and compresses the spring 126. When the limiting plate moves, the fixing block 129 and the trapezoidal block 120 move accordingly, causing them to slide on the inner wall of the rectangular movable hole in the dovetail groove 128 and disengage from the inner wall of the dovetail groove 128. At this time, the guide wheel assembly 13 can be removed from the support arm assembly 12. When installing a new guide wheel assembly 13, simply align the trapezoidal plate 1306 with the dovetail groove 128, and then push the trapezoidal plate 1306 along the dovetail groove 128. When the trapezoidal plate 1306 contacts the trapezoidal groove 128... When the inclined surface of the trapezoidal block 120 is reached, the trapezoidal block 120 will be pushed until the trapezoidal block 120 corresponds to the limiting groove opened in the dovetail groove 128. At this time, the rebound force of the spring 126 will push the slide rod 124 to reset, thereby moving the limiting plate 127 and the fixing block 129, pushing the trapezoidal block 120 into the interior of the limiting groove opened in the dovetail groove 128, and completing the fixed installation of the guide wheel assembly 13. The whole process is simple to operate and greatly improves the efficiency of maintenance and replacement. By activating stepper motor 212, gear 213 rotates, which in turn drives gear 214 to rotate limit plate 215. This, in turn, rotates bidirectional threaded rod 217, causing two sliders 218 to move simultaneously inward and outward on the outer wall of bidirectional threaded rod 217. This adjusts the tightness between anti-slip fixing plate 219 and guide assembly 11, enabling rapid clamping and releasing of guide assembly 11. Stepper motor 25 then drives shaft 26 to rotate. The rotating shaft 26 drives the gear 28 to rotate. The meshing transmission between the gear 28 and the gear 29 further drives the rotating rod 201 and the limiting rod 203 to rotate, so that the bevel gear 204 drives the bevel gear 206 to rotate, thereby driving the lead screw 207 to rotate. The rotation of the lead screw 207 pushes the slider 208 to move up and down. By moving the two sliders 208, the height position of the fixing plate 209 can be adjusted to adapt to the installation requirements of guide components 11 of different sizes, which can significantly improve the applicability and ease of operation of the equipment.
