Description

Technical Field

[0001] This utility model relates to a steel beam thermal straightening device, specifically, to a thermal straightening device for deformation of the top beam of a hydraulic support. Background Technology

[0002] In the coal mining industry, hydraulic supports are underground support equipment used to control mine pressure at the coal face. The roof beam is a crucial component of the hydraulic support, a large-tonnage structural component manufactured by assembling and welding steel plates. To ensure the roof beam can withstand the significant underground mine pressure without deformation, stiffening plates are welded to the roof plate. To guarantee the weld strength between the stiffening plates and the roof plate, large weld seams are often required. The welding process generates very high heat, causing thermal deformation of the roof plate, and residual stress remains after welding. Flame straightening is a method to release this stress. By heating the welded area at high temperature, the thermal deformation is corrected, and then natural cooling is allowed to release the residual stress.

[0003] In existing technologies, the heat straightening of the top beam of hydraulic supports is generally done manually, requiring manual operation of a handheld heat gun for localized heating. This manual heat straightening is inefficient and poses safety hazards. For reference, some existing automated equipment applicable to other plate parts, such as the CNC flame straightening machine for steel box girder plate units disclosed in Chinese Utility Model Patent CN202322228496.5, uses a translation mechanism that allows the gun head to move in three directions (X, Y, and Z), realizing dynamic adjustment of the straightening gun's working trajectory and achieving a high degree of automation; and a simple plate workpiece straightening machine disclosed in Chinese Utility Model Patent CN202320945091.0, which uses a gantry frame support on a track to move the heat gun assembly, achieving movement in two directions (X and Y) and automating the flame straightening process.

[0004] While the automated equipment disclosed above can replace manual labor to improve correction efficiency and prevent safety hazards, it also has certain drawbacks: the heating gun can only move along XYZ or XY and cannot swing to heat itself. Therefore, it is very likely to cause the heat input of the area to exceed the standard, which will lead to local overheating. In order to prevent this situation, it is necessary to increase the movement speed of the XYZ axis. However, there is always an upper limit to the movement speed. Therefore, the accuracy of its heat input is limited, and it cannot perform balanced and efficient heat correction for the deformed area.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a thermal correction device for the deformation of the top beam of a hydraulic support. This device can replace manual labor, automate the thermal correction process, and provide high precision in the heat input, enabling balanced and efficient thermal correction of the deformed area.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a heat gun, a swing plate, a rotating seat, and a movable frame. The heat gun is mounted on the swing plate, the swing plate swings on the rotating seat, and the rotating seat is rotatably mounted on the movable frame. The movable frame is used to drive the rotating seat to move along a first axis, a second axis, and a third axis that are perpendicular to each other. The second axis moves with the first axis, the third axis moves with the second axis, the rotating seat moves with the third axis, the third axis is perpendicular to the horizontal plane, and the rotation axis of the rotating seat is parallel to the third axis.

[0008] Based on the above, the swing plate is disposed on the side or bottom of the rotating seat, and the heat gun is configured to face a direction perpendicular to the third axis or a direction extending toward the third axis. The heat gun is used for heat correction from a horizontal direction or from above to below.

[0009] Based on the above, the rotating seat is provided with a fourth straight rail perpendicular to the third axis, and a linear slider is provided on the swing plate accordingly. The rotating seat is also provided with a swing motor, which drives the swing plate to slide along the fourth straight rail.

[0010] Based on the above, the swing plate has a swing groove perpendicular to the fourth straight rail on the plate surface facing the rotating seat. The swing motor is connected to a rocker arm, one end of which is connected to the output end of the swing motor, and the other end of which is slidably disposed in the swing groove.

[0011] Based on the above, a rotary cylinder is provided between the rotating seat and the moving frame, and the rotary cylinder drives the rotating seat to rotate on the moving frame.

[0012] Based on the above, the movable frame includes a first beam, a second beam, and a lifting plate. The second beam is disposed on the first beam, the lifting plate is disposed on the second beam, and the rotating seat is disposed at the bottom end of the lifting plate. The length direction of the second beam is consistent with the direction of the second axis, and the length directions of the first beam and the lifting plate are consistent with the direction of the third axis.

[0013] Based on the above, the bottom end of the first beam is provided with an I-beam wheel, the I-beam wheel rolls along the light rail, the light rail extends along the first axis, and the first beam is driven by the first motor to move along the first axis on the light rail.

[0014] Based on the above, the top of the first beam is provided with a first straight rail extending along the first axis, and the second beam is provided with a corresponding first slide block. The second beam is driven by a motor to move along the first axis on the first beam.

[0015] Based on the above, the second beam is provided with a second straight rail extending along the second axis, and a second slide is provided on the second beam accordingly. The lifting plate is provided on the second slide, and the second slide is driven by the second motor to move along the second axis on the second beam.

[0016] This utility model has substantial features and advancements compared to existing technologies. Specifically, the thermal correction device for the deformation of the hydraulic support top beam of this utility model has the following advantages: it can replace manual labor to improve correction efficiency and prevent safety hazards. Furthermore, by adding a rotation axis and a swing axis to the XYZ three axes, this device can also drive the heating gun to swing in a zigzag pattern during the automated thermal correction process, ensuring that different parts of the deformation area are heated evenly, guaranteeing the accuracy of the heat input for thermal correction, and ultimately achieving balanced and efficient thermal correction, resulting in a more precise thermal correction effect.

[0039] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0040] like Figures 1-11As shown, the thermal straightening device for the deformation of the hydraulic support top beam of this utility model includes a heating gun, a swing plate 50, a rotating seat 40, and a moving frame 100. The heating gun is used to heat the deformed area requiring thermal straightening at high temperature, allowing it to cool naturally and release residual stress, thus completing the straightening of the deformed area. The heating gun is mounted on the swing plate 50, which drives the heating gun to swing periodically. The swing plate 50 is oscillatingly mounted on the rotating seat 40, which drives the swing plate 50 and the heating gun to rotate at a certain angle. The rotating seat 40 is rotatably mounted on the moving frame 100, which drives the rotating seat 40 to move along mutually perpendicular first axes x, second axes y, and third axes z.

[0041] like Figure 1 As shown, the orientation directions of the first axis x, the second axis y, and the third axis z can form a mutually perpendicular three-axis translation coordinate system. The second axis y moves with the first axis x, and the third axis z moves with the second axis y. The third axis z is perpendicular to the horizontal plane, and the first axis x and the second axis y are both parallel to the horizontal plane. Moreover, the rotating seat 40 moves with the third axis z, and the rotation axis of the rotating seat 40 is parallel to the third axis z. The rotation axis of the rotating seat 40 forms the rotation axis a. The swing plate 50 moves with the rotating plate 40, and the swing plate 50 swings periodically on the rotating seat 40, forming the swing axis b.

[0042] It is worth noting that, Figures 1-11 The directions X, Y, Z, and B in the diagram refer to the orientation of the first axis x, the second axis y, the third axis z, and the oscillation axis b, respectively. The direction A refers to the same rotation direction as the rotation axis a, and does not directly refer to the first axis x, the second axis y, the third axis z, the rotation axis a, or the oscillation axis b.

[0043] Based on the above, the moving frame 100 drives the rotating seat 40 to move along the first axis x, the second axis y, and the third axis z. After moving, the heat gun will reach the vicinity of the deformation area that needs to be heat-corrected. By swinging the swing axis b, combined with linear movement along the first axis x, the second axis y, or the third axis z, or a combination of the three axes, or a combination of the three axes, when the swing direction is perpendicular to the linear movement direction, the heat gun can achieve a zigzag swing. Then, by rotating the rotating axis a, the direction of the heat gun can be adjusted, so that the swing direction of the swing axis b remains perpendicular to the linear movement direction of the heat gun, thus keeping the zigzag swing effective. The zigzag swing of the heat gun can ensure that the deformation area is heated evenly and can also improve the correction efficiency of the welding gun.

[0044] By oscillating the heat gun in a zigzag pattern, it is possible to ensure that different parts of the heating area receive uniform heat radiation, thereby avoiding local overheating or underheating. It can also expand the heating area, allowing heat to be transferred to the entire target area more quickly, thus shortening the heating time, improving heating efficiency, and saving energy and costs. Moreover, by oscillating the heat gun, it can be adapted to boards with complex shapes or irregular surfaces, achieving a more precise heating effect.

[0045] Therefore, by inputting specific coordinates, the heating torch can be driven by the moving frame 100, the rotating seat 40, and the swing plate 50. The heating torch moves along the first axis x, the second axis y, and the third axis z to a specific position, automatically, accurately, and efficiently performing heat correction on the deformed area that needs heat correction. Compared with manual heating, it has higher safety and heat correction efficiency. At the same time, during the automated heat correction process, the heating torch can also swing in a zigzag pattern to ensure that different parts of the deformed area are heated evenly, ensuring the accuracy of the heat input for heat correction, and finally completing a balanced and efficient heat correction.

[0046] Based on the above, the swing plate 50 is located on the side or bottom surface of the rotating seat 40, such as... Figure 4 , Figure 5 This is a schematic diagram of the swing plate 50 located on the side of the rotating base 40; the rotating shaft a mainly changes the swing direction of the grill gun, rather than the orientation of the grill gun, so the swing plate 50 and the grill gun can be located on the side or bottom of the rotating base 40.

[0047] Based on the above, the heating gun is fixed on the heating gun mounting base 60 on the swing plate 50. The heating gun is configured to face a direction perpendicular to the third axis z or a direction extending towards the third axis z. This allows the orientation of the heating gun to be determined so that it can be used to perform heat correction on the deformed area from a horizontal direction or from above.

[0048] As a preferred option, considering that some heating torches are quite long, in order to avoid damage to the heating torches due to interference during movement, when the swing plate 50 is located on the side of the rotating base 40, the heating torch is oriented towards the direction extending from the third axis z, that is, from top to bottom for heat correction; when the swing plate 50 is located on the bottom surface of the rotating base 40, the heating torch is oriented towards the direction perpendicular to the third axis z, that is, from the horizontal direction for heat correction.

[0049] like Figure 4 , Figure 5As shown, the rotating base 40 is provided with a fourth straight rail 51 perpendicular to the third axis z, and the swing plate 50 is provided with a corresponding linear slider 52. The rotating base 40 is also provided with a swing motor 53, which drives the swing plate 50 to slide along the fourth straight rail 51. Two parallel fourth straight rails 51 can be provided. The output end of the swing motor 53 is located between the two fourth straight rails 51 to ensure that the swing direction does not deviate. Furthermore, the surface of the swing plate 50 facing the rotating base 40 is provided with a swing groove 54 perpendicular to the fourth straight rail 51. Figure 5 (The location of the swing groove 54 is indicated by a dashed line). The swing motor 53 is connected to the rocker arm 55. One end of the rocker arm 55 is connected to the output end of the swing motor 53. The rocker arm 55 is driven by the swing motor 53 and rotates around the axis of the output end of the drive motor 53. The other end of the rocker arm 55 is slidably disposed in the swing groove 54. Specifically, the end of the rocker arm 55 is provided with a needle roller bearing, which can slide in the swing groove 54 along the length direction of the swing groove 54. While the rocker arm 55 rotates, it drives the swing plate 50 to swing along the direction of the fourth straight rail 51 to form the swing shaft b.

[0050] like Figure 4 As shown, a rotary cylinder 41 is provided between the rotating seat 40 and the movable frame 100. The rotary cylinder 41 connects the movable frame 100 and the rotating seat 40, and drives the rotating seat 40 to rotate on the movable frame 100. The rotation axis of the rotating seat 40 is parallel to the third axis z, forming a rotation axis a. Thus, when the rotating seat 40 rotates, it drives the swing plate 50 to rotate, that is, the rotation axis a drives the swing axis b to rotate. Of course, the use of a rotary cylinder 41 is not a limitation on the driving form of the rotating seat 40; other driving forms such as motors or electric cylinders can also be used to drive the rotation of the rotating seat 40.

[0051] like Figure 2 , Figure 3 As shown, the movable frame 100 includes a first beam 10, a second beam 20 and a lifting plate 30. The second beam 20 is disposed on the first beam 10, the lifting plate 30 is disposed on the second beam 20, and the rotating seat 40 is disposed at the bottom end of the lifting plate 30. The length direction of the second beam 20 is consistent with the direction of the second axis y, and the length directions of the first beam 10 and the lifting plate 30 are consistent with the direction of the third axis z.

[0052] like Figure 2 , Figure 3 , Figure 6As shown, the mobile frame 100 adopts the form of a gantry frame. Specifically, the bottom end of the first beam 10 is provided with I-beam wheels 11, and a light rail 12 is provided on the ground or other base surface. The I-beam wheels 11 roll along the light rail 12 and are embedded in the top surface of the light rail 12. To ensure the rolling stability of the first beam 10, two or more I-beam wheels 11 can be provided at the bottom end of each first beam 10, and the first beams 10 are arranged in pairs to support the second beam 20. The light rail 12 extends along the first axis x direction, and the first beam 10 is driven by the first motor 13 to move along the first axis x direction on the light rail 12. The specific driving method can be as follows: Figure 6 As shown, a first rack 14 is provided on the side of the light rail 12, and a first gear 15 that meshes with the first rack 14 is provided at the output end of the first motor 13. A reducer is also provided between the first motor 13 and the first gear 15. Figure 6 (The dashed lines in the image indicate the approximate positions of the first motor 13 and the reducer.) When a gantry frame is used, the second beam 20 moves along the first axis x as the first beam 10 moves, which means the second axis y moves along the first axis x.

[0053] like Figure 11 As shown, unlike the gantry frame of the mobile frame 100, the mobile frame 100 can also adopt a three-axis truss form. Specifically, the bottom end of the first beam 10 is fixed to the ground or other base surface, and the top end of the first beam 10 is provided with a track beam 19 for laying the first straight rail. The first straight rail extends along the first axis x direction at the top end of the first beam 10. To ensure the support performance of the first beam 10, two sets of first beams 10 are provided to support the double-row first straight rail. Each set of first beams 10 has two or more first beams 10 to support the track beam 19, that is, the total number of first beams 10 is set to 4, 6, 8, etc. The second beam 20 is provided with a corresponding first slide 18. The second beam 20 is driven by a motor to move along the first axis x direction on the first beam 10. The specific driving form can be a motor, gear, and rack. A drag chain is provided between the first slide 18 and the track beam 19. When using a gantry frame, the second beam 20 itself moves along the first straight rail on the first beam 10, that is, the second axis y moves with the first axis x.

[0054] like Figure 2 , Figure 7 , Figure 8 As shown, a second straight rail 21 extending along the second axis is provided on the second beam 20, and a second slide block 22 is correspondingly provided on the second beam 20. The lifting plate 30 is movably mounted on the second slide block 22. To ensure the sliding stability of the second slide block 22 on the second beam 20, a double row of second straight rails 21 is provided. The second slide block 22 is driven by the second motor 23 to move along the second axis y direction on the second beam 20. The specific driving method can be as follows: Figure 8As shown, a second rack 24 is provided on the second beam 20 between the two second straight rails 21, and a second gear 25 that meshes with the second rack 24 is provided at the output end of the second motor 23. A reducer is also provided between the second motor 23 and the second gear 25. A drag chain is also provided between the second slide 22 and the second beam 20. Thus, the lifting plate 30 on the second slide 22 moves with the second beam 20, that is, the third axis z moves with the second axis y.

[0055] like Figure 9 , Figure 10 As shown, the lifting plate 30 is provided with a third straight rail 31 extending along the third axis. To ensure the sliding stability of the lifting plate 30, the third straight rails 31 are arranged in pairs on both sides of the lifting plate 30. The second slide block 22 is provided with a guide rail base 32, which is arranged in pairs with the third straight rails 31. The lifting plate 30 is driven by the third motor 33 to move along the third axis z direction on the second slide block 22. The specific driving form can be as follows. Figure 10 As shown, the lifting plate 30 is also equipped with a third rack 34, and the output end of the third motor 33 is equipped with a third gear 35 that meshes with the third rack 34. A reducer is also provided between the third motor 33 and the third gear 35. Figure 10 (The approximate positions of the third motor 33 and the reducer are indicated by dashed lines). To prevent the third straight rails 31 on both sides of the lifting plate 30 from being contaminated by dust and other impurities, a front guard plate 36 and a rear guard plate 37 are respectively installed on the two plates of the lifting plate 30. Thus, the rotating seat 40 is located at the bottom of the lifting plate 30, and the moving seat 40 moves with the lifting plate 30, that is, the rotating shaft a moves with the third shaft z.

[0056] Based on the above, when the first axis x moves, it can drive the second axis y, the third axis z, the rotation axis a, and the swing axis b to move; when the second axis y moves, it can drive the third axis z, the rotation axis a, and the swing axis b to move; when the third axis z moves, it can drive the rotation axis a and the swing axis b to move; when the rotation axis a rotates, it can drive the swing axis b to rotate.

[0057] Based on the above, the mobile frame 100 is also equipped with an electrical control cabinet 70. The electrical control cabinet 70 can be equipped with a PLC and an input module (such as a touch screen) to control the quantitative and speed movement of the heating gun by inputting coordinate points. It can also integrate a teaching pendant to pre-teach the trajectory to realize the automated thermal correction of the top beam. The PLC may include a micro-numerical motion controller, which can control the movement trajectory, speed, rotation and other functions of the heating gun. By controlling the motor speed, the heating time and speed can be controlled, which can achieve more thorough stress release.

[0058] like Figure 12 As shown, for ease of understanding, this utility model also discloses a process for thermally correcting the deformation of the hydraulic support top beam based on the above-mentioned thermal correction device, as follows:

[0059] The first step is to determine the flatness of the top beam. If the flatness of the top beam is not up to standard, it needs to be heat-corrected; if it is up to standard, it can be transported.

[0060] The second step is thermal straightening, which includes positioning marking, programmed straightening, and natural cooling. Specifically:

[0061] Positioning and marking: Place the top beam at the workstation, determine the position to be corrected, determine the zero point position of the heating gun, mark the area to be corrected, and plan the movement path of the heating gun during heating.

[0062] The program is designed to correct the movement of four axes (x-axis, y-axis, z-axis, and a-axis) in a step-by-step manner, setting the movement coordinates and speeds (the movement speed is calculated based on the distance between the torch and the workpiece, the torch temperature, and the swing distance). The program can be written in either relative or absolute coordinates. For relative coordinates, the distance each axis moves at each step is input; for absolute coordinates, the target coordinates at the same zero point are input.

[0063] After the heat-corrected top beam has been moved to a naturally ventilated area, it will be allowed to cool naturally for 3-4 hours. Then, repeat step one to check if the flatness of the top beam is up to standard. If it is not up to standard, it needs to be corrected again.

[0064] The programming difficulty of the above process steps is relatively low. It only requires inputting the coordinates and speed of each axis movement. Moreover, after determining the weld position (i.e., deformation position) on the top beam of the hydraulic support, only one program modification is needed for a batch of workpieces, without the need for reprogramming.

[0065] The thermal correction device for the deformation of the hydraulic support top beam of this utility model can replace manual labor to improve correction efficiency and prevent safety hazards. Furthermore, by adding a rotation axis a and a swing axis b to the XYZ three axes, the device can also drive the heating gun to swing in a zigzag pattern during the automated thermal correction process, ensuring that different parts of the deformation area are heated evenly, guaranteeing the accuracy of the heat input for thermal correction, and ultimately achieving balanced and efficient thermal correction, resulting in a more precise thermal correction effect.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
