[0040] To facilitate those skilled in the art to understand the present invention, specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense.

[0042] like Figure 1 As shown, the present invention provides a high-precision laser ranging type rolling mill push bed, including a first rolling roller 2 arranged on the input side of the rolling mill body 1, and also including a rolling steel centering mechanism 3 and a laser ranging device arranged on both sides of the first rolling steel roller 2; the rolling mill body 1 and the first rolling steel roller 2 are arranged in a pit, and the rolling steel centering mechanism 3 is arranged on the ground on both sides of the pit, and is used to push and align the rolled steel that is skewed during transportation; the laser ranging device is used to detect whether the rolled steel transported on the first rolling steel roller 2 is skewed, and a pushing mechanism is provided on the upper side of the first rolling steel roller 2, and the pushing mechanism is used to push the rolled steel into the rolling mill body 1.

[0043] like Figure 2 As shown, the first steel rolling roller 2 includes a U-shaped roller base 4 and a steel rolling roller 5 rotatably matched to the roller base 4. The side of the roller base 4 is provided with a drive motor 6 corresponding to the steel rolling roller 5. The drive motor 6 is installed on the side of the roller base 4 through a motor bracket 7, corresponding to the position of the steel rolling roller 5; the side roller shaft of the steel rolling roller 5 extends out of the roller base 4 and is fixed to the motor shaft of the drive motor 6 through a coupling, and the drive motor 6 drives the steel rolling roller 5 to rotate synchronously; the inner side of the roller base 4 is provided with a jacking switching mechanism 8, which is used to lift the steel rolling and separate it from the conveyor roller during the process of steel rolling centering; thereby avoiding wear on the conveyor roller caused by lateral movement during steel rolling centering; as shown Figure 3-4 As shown, the jacking switching mechanism 8 includes a jacking cylinder 9 arranged on the inner side of the roller base 4, and a jacking base plate 10 is provided on the pushing head of the jacking cylinder 9; a guide wheel base plate 11 is vertically provided on the upper side of the jacking base plate 10, and the guide wheel base plate 11 is located between two adjacent steel rolling rollers 5; a U-shaped guide wheel frame 12 is provided on the upper side of the guide wheel base plate 11, and the feed roller 13 is rotatably matched on the guide wheel frame 12; transverse support plates 14 are provided on both sides of the jacking base plate 10, and the transverse support plates 14 are slidably matched with the jacking base plate 10 through the adjusting slide shaft 15; the lower side of the adjusting slide shaft 15 passes through the jacking base plate 10 and is fixed to the adjusting plate 16; a switching component is provided on the lower side of the jacking base plate 10, and the switching component is used to adjust the height position of the transverse support plate 14.

[0044] like Figure 5As shown, when the laser ranging device detects that the rolled steel on the first rolling steel roller 2 is skewed, the switching component is actuated to adjust the transverse support plate 14 upward so that the upper side of the transverse support plate 14 exceeds the feed roller 13; the lifting cylinder 9 extends, driving the lifting base plate 10 to move upward, so that the transverse support plate 14 and the feed roller 13 on the guide wheel base plate 11 rise synchronously and pass through between the rolling steel rollers 5; during the rising process, the transverse support plate 14 will contact the bottom of the rolled steel and gradually lift the rolled steel to separate it from the surface of the rolling steel roller 5, avoiding direct friction between the rolled steel and the rolling steel roller 5 during the subsequent centering process; after the rolled steel is lifted, the rolling steel centering mechanism 3 starts to apply symmetrical thrust to both sides of the rolled steel, pushing the rolled steel to move laterally on the transverse support plate 14; after the rolled steel is centered, the switching component is actuated to adjust the transverse support plate 14 downward The transverse support plate 14 is moved horizontally so that the transverse support plate 14 is lower than the feed roller 13, the bottom of the rolled steel contacts the upper surface of the feed roller 13, and the rolled steel is pushed into the rollers of the rolling mill body 1 through the pushing mechanism; if the laser ranging device does not detect the skewness of the rolled steel, the switching component does not switch, and the transverse support plate 14 is lower than the feed roller 13; the lifting cylinder 9 extends, driving the lifting base plate 10 to move upward, the feed roller 13 directly contacts the bottom of the rolled steel, and the rolled steel is pushed into the rolling mill body 1 through the pushing mechanism; the rolled steel is pushed into the rolling mill body 1 by cooperating with the feed roller 13 through the pushing mechanism, thereby replacing the friction force of the rolled steel roller 5 to push the rolled steel into the rolling mill body 1, reducing the friction of the feed roller 13; at the same time, the feed roller 13 is more compact than the rolled steel roller 5 and is easy to replace.

[0045] The lifting switching mechanism 8 realizes the separation of the rolled steel and the rolled steel roller 5 through the lifting cylinder 9, which fundamentally eliminates the friction and wear between the rolled steel and the rolled steel roller 5 during the traditional centering process, and extends the service life of the rolled steel roller 5; and the cooperative pushing method of the pushing mechanism and the feed roller 13 replaces the traditional mode of conveying that relies on the friction force of the rolled steel roller 5. By combining active pushing with the rolling support of the feed roller 13, the relative sliding of the rolled steel bottom and the conveying components is reduced, the risk of scratching the rolled steel surface is reduced, and the pushing force is more stable and controllable.

[0046] The rolling steel centering mechanism 3 starts to apply symmetrical thrust to both sides of the rolling steel, pushing the rolling steel to move horizontally on the transverse support plate 14; the transverse support plate 14 may be worn and the rolling steel surface may also be scratched; in order to solve this problem, Figure 6 As shown, a mounting groove is provided on the upper side of the transverse support plate 14, and a number of transverse guide wheels 23 are rotatably fitted in the mounting groove; the upper side of the transverse guide wheel 23 exceeds the upper side of the transverse support plate 14, and the upper side of the transverse guide wheel 23 forms a horizontal rolling surface, which reduces wear during steel rolling centering.

[0047] like Figure 4As shown, the switching component includes a double-head switching cylinder 17, which is fixed to the lower side of the lifting base plate 10 through a U-shaped cylinder bracket 18; both sides of the double-head switching cylinder 17 pass through the cylinder bracket 18 and are fixed to one end of the switching active shaft 19, and the other end of the switching active shaft 19 is fixed to the arc-shaped push sleeve 20; the lower side of the adjustment plate 16 is fixed to the switching driven shaft 22 through the mounting ear 21, and the switching driven shaft 22 is slidably fitted in the push sleeve 20; when the switching component adjusts the height of the transverse support plate 14, the double-head switching cylinder 17 is started, and its push heads on both sides extend axially. out, driving the switching active shaft 19 fixed thereto to move outward synchronously; since the arc-shaped push sleeve 20 at the other end of the switching active shaft 19 slides with the switching driven shaft 22 on the lower side of the adjusting plate 16, when the switching active shaft 19 moves outward, the trajectory of the arc-shaped push sleeve 20 forces the switching driven shaft 22 to slide downward along the arc groove of the push sleeve 20, and the switching driven shaft 22 drives the adjusting plate 16 to descend through the mounting ear 21, and the adjusting plate 16 then pushes the adjusting slide shaft 15 to cause the transverse support plate 14 to descend.

[0048] This application uses a specifically structured lifting switching mechanism 8 (including a switching component, a lifting cylinder 9, etc.) and a laser ranging device, as well as a rolling mill centering mechanism 3, to coordinate and adjust the raising and lowering of the transverse support plate 14 through the switching component (supporting the rolling mill during centering and withdrawing during transportation), and combines the lifting cylinder 9 to separate the rolling mill from the rolling mill roller 5, thereby realizing switching between skewed and non-skewed working conditions.

[0049] like Figure 7-8 As shown, the steel rolling centering mechanism 3 includes a centering base 24 provided on the ground, with shaft seats 25 provided at the four corners of the centering base 24, a centering sliding shaft 26 slidingly engaged with the shaft seat 25, and an end portion of the centering sliding shaft 26 slidingly engaged with a centering movable seat 27; a push shaft 29 is fixed to the upper side of the centering movable seat 27 through a push ear 28; a cylinder fixing plate 30 is vertically provided on the centering base 24, a centering cylinder 31 is fixed on the cylinder fixing plate 30, and a push head of the centering cylinder 31 passes through the cylinder fixing plate 30 and is fixed to the push shaft 29 ; A roller mounting groove 32 that passes through the centering movable seat 27 and the contact side of the rolled steel is opened from top to bottom, and the position of the roller mounting groove 32 corresponds to the position of the rolled steel roller 5; a roller plate 33 is detachably installed on the upper side of the roller mounting groove 32 through a locking piece (bolt), and a centering roller 34 is rotatably fitted on the roller plate 33 through a bearing; the centering cylinder 31 extends, driving the centering movable seats 27 on both sides to be relatively close, and the centering roller 34 contacts both sides of the rolled steel, exerting a symmetrical thrust to push the rolled steel to move laterally on the transverse support plate 14 for centering.

[0050] When the roller contacts the hot steel billet, impurities such as iron oxide scale, metal debris, rolling oil, etc. will continue to accumulate. These impurities will directly cause the roller surface to wear, resulting in scratches and contamination on the product surface. It is necessary to manually use the spray pipe to regularly clean and remove impurities. In order to solve this problem, such as Figure 9-10As shown, a main spray pipe 35 is fixed on the upper side of the centering movable seat 27, and the water inlet side of the main spray pipe 35 is connected to the external water source through a hose. A branch pipe 36 is provided on the main spray pipe 35, and a threaded interface is provided on the outer side of the branch pipe 36; threaded interfaces are provided on the upper and lower sides of the roller plate 33 respectively; the branch pipe 36 is connected to the threaded interface on the upper side of the roller plate 33 through a water guide hose 37, and the threaded interface on the lower side of the roller plate 33 is connected to one end of the water guide bellows 38, and the other end of the water guide bellows 38 is connected to the cleaning nozzle 39; Spray reversing components are provided on both sides of the movable seat 27, and a reversing shaft 40 is provided between the spray reversing components.

After the reversing drive component contacts the spray reversing component, it drives the reversing shaft 40 to rotate 90 degrees, thereby driving the cleaning nozzle 39 to rotate 90 degrees to face the rolling roller 5.

[0051] like Figure 11As shown, the spray reversing component includes an n-shaped spray reversing frame 42 and a reversing head 43. The spray reversing frame 42 is fixed to the side of the centering base 24.
