Description

Technical Field

[0001] The present invention relates to the technical field of steel rolling equipment, in particular to a ground guide support structure. Background Art

[0002] A guide is a device installed before and after the roll pass during the steel rolling process to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state.

[0003] The rolling mills in the mill area of bar and high-speed wire production lines typically have guides installed at the entrance and exit to assist the mill in engaging and rolling the workpiece. Guides are typically secured in two ways: one is a guide beam structure with guides mounted directly on the mill body; the other is a floor-mounted support structure with guides secured to a separate floor-mounted guide support. This structure maintains a fixed guide centerline, reducing the need for guide adjustments on the production line and saving adjustment time.

[0004] Existing floor-standing guide supports are divided into two types: one is that the floor-standing guide support and the bracket on which the guide is fixed are fixed. When replacing the guide and changing the rolls of the rolling mill, an overhead crane is required to lift the guide and the guide bracket, which is labor-intensive, labor-intensive and time-consuming; the other is that the guide support is fixed on the foundation, and the guide bracket can rotate around the rotating axis on the guide support. This type of guide support structure facilitates the rolling mill roll changing, is easy to use, and is widely used. However, the second type of floor-standing rotating support has the following problems: when the rolling mill rolls are changed, the rotation opening of the guide bracket must meet the requirements of a rolling mill roll changing position, the rotation angle must be at least 90°, and the rotation radius cannot be too small, which will increase the spacing between the rolling mills and affect the overall layout of the rolling process; the guide and bracket will interfere with the lower crossbeam of the rolling mill during rotation, resulting in obstructed rotation; due to the harsh environment in the rolling mill area, the rotating shaft is often rusted and stuck, and manual cooperation with the overhead crane is required to complete the rotation, which is labor-intensive and time-consuming, and has low work efficiency; the tipping moment of the guide is relatively large during rolling, and the rotating shaft with a hollow structure is easily broken.

[0050] The invention discloses a floor-standing guide support structure, which requires little space for roller changing and small rolling mill spacing requirements, shortens the overall process layout length, and avoids interference with rolling mill beams.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1 to 5 The floor-standing guide support structure of the present invention includes a base 1, on which are disposed a first guide rail 31 and a second guide rail 39 arranged in parallel. A horizontal guide bracket 2 is slidably connected to the first guide rail 31, and a vertical guide bracket 7 is slidably connected to the second guide rail 39. The first and second guide rails 31 and 39 are arranged along the conveying direction of the profile. The horizontal guide bracket 2 is driven by a first power device 12 to slide along the first guide rail 31, and the vertical guide bracket 7 is driven by a second power device 11 to slide along the second guide rail 39.

[0053] The vertical guide bracket 7 supports the vertical guide 8, while the horizontal guide bracket 2 supports the horizontal guide 4. The vertical guide 8 limits the vertical position of the passing bars or high wires, while the horizontal guide 4 limits the horizontal position of the passing bars or high wires. The outlet of the horizontal guide 4 corresponds to the horizontal rolling mill 3, while the inlet of the vertical guide 8 corresponds to the vertical rolling mill 9. The first guide rail 31 and the second guide rail 39 are fixed to the top of the base 1.

[0054] In the floor-standing guide support structure of the present invention, the horizontal guide bracket 2 and the vertical guide bracket 7 are connected to the base 1 by sliding linearly along the guide rail. When the bar needs to be supported, the horizontal guide bracket 2 or the vertical guide bracket 7 slides out of the base 1. When the rolling mill changes rolls, the horizontal guide bracket 2 or the vertical guide bracket 7 slides back to the top of the base 1. Compared with the guide supports with a rotating arrangement in the prior art, the required space is small, the rolling mill spacing requirement is small, the total process layout length is shortened, and the length of the factory building is saved. When driven by the power device, the horizontal guide bracket 2 and the vertical guide bracket 7 move in a straight line, avoiding interference with the rolling mill beam during rotation. And because the support structure of the present invention does not require a rotating shaft, the occurrence of problems such as rust or breakage of the rotating shaft is avoided. The horizontal guide bracket 2 is driven to slide by the first power device 12, and the vertical guide bracket 7 is driven to slide by the second power device 11, which is more convenient to use.

[0055] In order to ensure the reliability of the sliding connection between the horizontal guide bracket 2 and the first guide rail 31, a first limit plate 204 is provided at the bottom end of the horizontal guide bracket 2. Figure 3 As shown, the first limit plate 204 is slidably connected to the side of the first guide rail 31, and the bottom surface of the horizontal guide bracket 2 is slidably connected to the top surface of the first guide rail 31. Specifically, two first limit plates 204 are provided, and the two first limit plates 204 are symmetrically arranged on both sides of the first guide rail 31, effectively preventing the horizontal guide bracket 2 from deviating from the first guide rail 31 during sliding.

[0056] Similarly, in order to ensure the reliability of the sliding connection between the vertical guide bracket 7 and the second guide rail 31, a second limiting plate 701 is provided at the bottom end of the vertical guide bracket 7. Figure 4 As shown, the second limit plate 701 is slidably connected to the side of the second guide rail 39, and the bottom surface of the vertical guide bracket 7 is slidably connected to the top surface of the second guide rail 39. Specifically, two second limit plates 701 are provided, and the two second limit plates 701 are symmetrically arranged on both sides of the second guide rail 39 to prevent the vertical guide bracket 7 from deviating from the second guide rail 39 during sliding.

[0057] To improve the wear resistance and corrosion resistance of the sliding connection between the horizontal guide bracket 2 and the first guide rail 31, a first wear-resistant plate 25 is fixedly connected to the bottom surface of the horizontal guide bracket 2 at a position corresponding to the top surface of the first guide rail 31, and a second wear-resistant plate 26 is fixedly connected to the position where the first limit plate 204 is slidingly connected to the side of the first guide rail 31. The first wear-resistant plate 25 and the second wear-resistant plate 26 are in sliding contact with the first guide rail 31.

[0058] In one embodiment, the first wear-resistant plate 25 and the second wear-resistant plate 26 are connected to the horizontal guide bracket 2 by screws, so that the first wear-resistant plate 25 or the second wear-resistant plate 26 can be replaced after being worn. The first wear-resistant plate 25 and the second wear-resistant plate 26 are made of copper or modified nylon.

[0059] To improve the wear and corrosion resistance of the sliding connection between the vertical guide bracket 7 and the second guide rail 39, a third wear-resistant plate 33 is fixedly connected to the bottom surface of the vertical guide bracket 7 at the position corresponding to the top surface of the second guide rail 39. A fourth wear-resistant plate 34 is fixedly connected to the position where the second limit plate 701 slides against the side of the second guide rail 39. The third and fourth wear-resistant plates 33, 34 are connected to the vertical guide bracket 7 with screws, facilitating replacement of the third and fourth wear-resistant plates 33, 34 if worn. The third and fourth wear-resistant plates 33, 34 are made of copper or modified nylon.

[0060] In order to prevent the horizontal guide bracket 2 from tipping over, the first limit plate 204 is provided with a first rolling structure 27 on the side close to the first guide rail 31. Figure 3 As shown, the first rolling structure 27 is rotatably disposed within a first limiting guide groove 32, which is disposed on the side of the first guide rail 31. The first limiting guide groove 32 extends along the length of the first guide rail 31 and is arranged parallel to the first guide rail 31 to prevent the first rolling structure 27 from interfering with the sliding of the horizontal guide bracket 2 along the first guide rail 31. The first rolling structure 27 is connected to the first limiting plate 204 via a rotating shaft. The provision of the first rolling structure 27 prevents the horizontal guide bracket 2 from tipping over and reduces friction with the first limiting guide groove 32.

[0061] In order to prevent the vertical guide bracket 7 from tipping over, the second limiting plate 701 is provided with a second rolling structure 40 near the side of the second guide rail 39. The second rolling structure 40 is rotatably provided in the second limiting guide groove 36. The second limiting guide groove 36 is provided on the side of the second guide rail 39. The second limiting guide groove 36 extends along the length direction of the second guide rail 39, and the second limiting guide groove 36 is provided in parallel with the second guide rail 39. Figure 4 As shown, the second rolling structure 40 is prevented from interfering with the sliding of the vertical guide bracket 7 along the second guide rail 39. The second rolling structure 40 is connected to the second limiting plate 701 via a rotating shaft. The second rolling structure 40 can prevent the vertical guide bracket 7 from tipping over and reduce friction with the second limiting guide groove 36.

[0062] Furthermore, the first rolling structure 27 and the second rolling structure 40 are both cylindrical rollers, which are standard parts and can be easily replaced after being worn.

[0063] In one embodiment, the first power device 12 is a first hydraulic cylinder, one end of which is rotatably connected to the base 1, and the other end is hinged to the bottom end of the horizontal guide bracket 2. The second power device 11 is a second hydraulic cylinder, one end of which is rotatably connected to the base 1, and the other end is hinged to the bottom end of the vertical guide bracket 7. In order to avoid interference, the horizontal guide bracket 2 and the vertical guide bracket 7 are respectively arranged at both ends of the base 1. The first guide rail 31 includes two parallel track support plates, and the first hydraulic cylinder is arranged between the two track support plates of the first guide rail 31. The second guide rail 39 also includes two parallel track support plates, and the second hydraulic cylinder is arranged between the two track support plates of the second guide rail 39.

[0064] The rod end of the first hydraulic cylinder is rotatably connected to the first connecting plate 30 at the bottom of the horizontal guide bracket 2 through the first pin 28. In order to reduce the friction at the connection position, the rod end of the first hydraulic cylinder is rotatably connected to the first pin 28 through the first bearing 29. Figure 3 As shown. The rod end of the second hydraulic cylinder is rotatably connected to the second connecting plate 35 at the bottom of the vertical guide bracket 7 through the second pin 38. In order to reduce the friction at the connection position, the rod end of the second hydraulic cylinder is rotatably connected to the second pin 38 through the second bearing 37, as shown. Figure 4 shown.

[0065] The first hydraulic cylinder and the second hydraulic cylinder are both trunnion type hydraulic cylinders. Figure 6 As shown, the ear shaft is rotatably connected to the base body 16 through the copper sleeve 17, and the base body 16 is installed on the track support plate.

[0066] To prevent water from entering the rolling zone and the housing of base 1, the top covers of the first and second hydraulic cylinders are equipped with sealing steel plates 14, which are connected to the housing structure of base 1 via sealing bolts 15. A drain port is provided on base 1 to allow any splashing water into the housing to escape. Telescopic tubes 13 are sleeved around the piston rods of the first and second hydraulic cylinders to prevent water or impurities from falling onto the piston rods, extending their service life.

[0067] To facilitate connection with the corresponding guide, the horizontal guide bracket 2 is fixedly connected to the horizontal guide 4 via a first locking structure. Specifically, the first locking structure includes a first limiting groove 202 and a positioning flat key 22 disposed on the bottom surface of the first limiting groove 202. The first limiting groove 202 is also provided with a limiting groove pressure plate 21. The limiting groove pressure plate 21 is connected to the bottom surface of the first limiting groove 202 near the groove side via a limiting bolt 23. The limiting groove pressure plate 21 is used to compress and limit the horizontal guide 4 connected to the first limiting groove 202. The connection between the first limiting groove 202 and the limiting groove pressure plate 21 forms a dovetail groove structure, and the bottom ends of the horizontal guide bracket 2 and the horizontal guide 4 are slidably connected by the dovetail groove structure. The horizontal guide bracket 2 is positioned by the positioning flat key 22 to prevent the horizontal guide 4 from sliding out along the dovetail groove structure.

[0068] To facilitate connection of the limiting groove pressure plate 21, a sliding connection groove 203 is provided on the bottom surface of the first limiting groove 202. The extending direction of the sliding connection groove 203 is the same as that of the first limiting groove 202. The head end of the limiting bolt 23 is slidably connected in the sliding connection groove 203. The tail end of the sliding connection groove 203 is fixedly connected to one side of the first limiting groove 202 by a limiting nut. One side of the guide structure connected to the first limiting groove 202 is limited by the side wall of the first limiting groove 202, and the other side is limited by the limiting groove pressure plate 21.

[0069] Specifically, such as Figure 7 As shown, the first limiting groove 202 includes a first groove side surface 2021 and a second groove side surface 2022, and the first groove side surface 2021 and the second groove side surface 2022 are respectively arranged on both sides of the groove bottom surface of the first limiting groove 202. The angle between the first groove side surface 2021 and the groove bottom surface is a first acute angle, and the angle between the second groove side surface 2022 and the groove bottom surface is a first obtuse angle. The limiting groove pressure plate 21 contacts the second groove side surface 2022. The angle between the first plate side surface of the limiting groove pressure plate 21 close to the second groove side surface 2022 and the groove bottom surface of the first limiting groove 202 is a second obtuse angle, and the angle between the second plate side surface of the limiting groove pressure plate 21 away from the second groove side surface 2022 and the groove bottom surface of the first limiting groove 202 is a second acute angle. In order to achieve reliable contact between the first plate side surface of the limiting groove pressure plate 21 and the second groove side surface 2022, the first obtuse angle and the second obtuse angle are the same. The first acute angle and the second acute angle can be the same or different.

[0070] Similarly, the vertical guide bracket 7 is fixedly connected to the vertical guide 8 through a second locking structure. The second locking structure is the same as the first locking structure. The difference between the two is that the first limiting groove 202 of the first locking structure is horizontally arranged, and the second limiting groove 702 of the second locking structure is vertically arranged. The horizontal and vertical here are both referred to the base 1, and will not be repeated here.

[0071] To improve the securement of the vertical guide 8, a lifting structure 10 is also provided on the vertical guide bracket 7. This lifting structure 10 is located at the bottom end of the second locking structure and is used to lift the bottom of the vertical guide 8. Specifically, the lifting structure 10 includes a support plate 1003 fixedly connected to the vertical guide bracket 7. A first push screw 1002 is threadedly connected to the support plate 1003, and the tail end of the first push screw 1002 corresponds to the bottom step surface of the vertical guide 8. The support plate 1003 supports the bottom end surface of the vertical guide 8, and the tail end of the first push screw 1002 supports the bottom step surface of the vertical guide 8, using the first push screw 1002 to assist in supporting the guide upward with its gravity. A locking nut 1004 is provided on the first push screw 1002, and an adjustment pad 1001 is placed on the support plate 1003. Because the guide heights of different manufacturers may vary, it is necessary to replace the adjustment pad 1001 with different thicknesses.

[0072] In order to reduce the temperature of the rolling mill, the floor-standing guide support structure of the present invention also includes a rolling mill cooling mechanism, which includes a first spray pipe 41 and a second spray pipe 42. The first spray pipe 41 and the second spray pipe 42 are both connected to the infusion pipe. Specifically, the first spray pipe 41 and the second spray pipe 42 are connected to the hose 44 through a quick-change joint 43. The hose 44 is a tube with steel wire wrapped around the outside of the tube. The hose 44 is connected to the infusion pipe through a welding head 45. The first spray pipe 41 is arranged at one end of the horizontal guide bracket 2 close to the horizontal rolling mill 3, and is used to cool the horizontal rollers of the horizontal rolling mill 3. The second spray pipe 42 is arranged at one end of the vertical guide bracket 7 close to the vertical rolling mill 9, and is used to cool the vertical rollers of the vertical rolling mill 9.

[0073] The floor-standing guide support structure of the present invention also includes a guide groove 5, one end of which is connected to the horizontal guide bracket 2, and the other end is connected to the vertical guide bracket 7, thereby guiding the blank located between the horizontal guide bracket 2 and the vertical guide bracket 7. In order to facilitate the connection with the guide groove 5, two vertical plates 201 are provided at the top of the horizontal guide bracket 2, and the guide groove 5 is placed between the two vertical plates 201. A threaded hole is provided on the vertical plate 201, and this threaded hole is used to connect a second top screw, and the second top screw tightens the guide groove 5 from both sides. A pin hole is left on the vertical guide bracket 7, and this pin hole is used to connect a positioning pin 6. The positioning pin 6 is used to fix the other end of the guide groove 5 to the vertical guide bracket 7, so as to achieve triangular positioning of the guide groove 5, which is stable and reliable. After the guide is installed, if the distance between the front and rear rolling mills (horizontal rolling mill 3 and vertical rolling mill 9) is too far due to the insufficient length of the guide, which is not conducive to the passage of billets, a guide groove 5 needs to be installed in the middle gap. One end of the guide groove 5 is tightened by the second push screw, and the second push screw can also be slightly adjusted left and right to facilitate the alignment of the guide groove 5 with the guide exit. The guide at the mill exit and the exit of the rear frame equipment are connected through the middle guide groove 5. When replacing the guide or the guide bracket, the guide groove 5 is lifted away, and the guide and guide bracket are pulled out of the rolling mill by the hydraulic cylinder on the base 1. The guide is replaced offline and the mill is pulled out to change the rollers.

[0074] Since the horizontal guide bracket 2 is close to the first spray pipe 41, in order to prevent the spray water from splashing onto the base 1, the end of the first guide rail 31 close to the first spray pipe 41 is sealed by the first sealing cover 19. Since the vertical guide bracket 7 is close to the second spray pipe 42, in order to prevent the spray water from splashing onto the base 1, the end of the second guide rail 39 close to the second spray pipe 42 is sealed by the second sealing cover 20.

[0075] After the horizontal and vertical guide brackets 2 and 7 are installed on the base 1, a first wedge 18 is used to limit the position of the guide brackets at one end, and a second wedge 24 is used to limit the position of the other end. A wedge on each side of the brackets serves as a locking mechanism. After the guide brackets are fully secured, the hydraulic cylinders fully stroke and release pressure. The hydraulic cylinders are not subject to impact loads, eliminating the risk of oil leakage and ensuring reliable and stable mechanical locking. The locking mechanism can also be designed without the wedges. After the hydraulic cylinders fully stroke, the hydraulic cylinders press against the inclined surface of the brackets and maintain pressure. This hydraulic locking method ensures automated control.

[0076] The horizontal guide bracket 2 and the vertical guide bracket 7 are both cast steel parts with strong integrity and meet the force requirements.

[0077] The base 1 of the floor-standing guide support structure of the present invention is a frame welding structure, which is fixed to the foundation by anchor bolts and shear grooves. It is impact-resistant, strong and stable. The assembly is separated from the rolling mill, which is beneficial to protecting the online rolling mill.
