Description

[0002] The weld connecting the railway sound barrier column and the base plate must meet the requirements of a Class I weld. Molten iron is usually used for welding. Due to the fluidity of molten iron, the joint to be welded needs to be facing upwards. Therefore, the column and base plate need to be flipped multiple times during the welding process to weld the joints on different sides. The railway sound barrier columns are 2-4 meters long, large in size and weight. If they are flipped manually, it would be time-consuming and labor-intensive. In internal research, the inventors came up with the idea of ​​designing a welding device for the column and base plate. After the column and base plate are installed on the welding device, a motor is used to flip the column and base plate.

[0003] However, since the cross-sectional shape of the railway sound barrier column is not circular, how to maintain stable support for the column during its rotation around its central axis has become a problem to be solved. Utility Model Content

[0018] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0023] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connected," "linked," "equipped with," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0024] The present invention will now be described in conjunction with the accompanying drawings and specific embodiments: Combination Figures 1 to 8 In a first aspect, the present invention provides a supporting rotation device, including a base 1 and a supporting structure 2 that are rotated together. A limiting channel 21 is provided in the middle of the supporting structure 2, through which a target component can pass. A limiting support part 23 is provided on the side wall of the limiting channel 21, which is used to support and limit the target component.

[0025] The limiting support 23 can be the inner wall of the limiting channel 21. The limiting channel 21 can be configured to match the size of the target component, so that the target component passing through the limiting channel 21 can be engaged with the support structure 2, and the target component can contact the side wall of the limiting channel 21.

[0026] In an optional embodiment, the inner wall of the limiting channel 21 is configured to fit the shape of the target component. For example, when the target component's interface is rectangular, the cross-section of the limiting channel 21 is also rectangular, and the dimensions of the two are similar, allowing the target component to be engaged by the limiting channel 21 of the support structure 2. In this case, the inner wall of the limiting channel 21 is in contact with at least part of the outer wall of the target component, which can apply a supporting force to the target component, allowing the support structure 2 to support the target component. At the same time, since the support structure 2 and the target component are engaged, by configuring the rotation axis of the support structure 2 relative to the base 1 to coincide with the rotation axis of the target component, the target component can drive the support structure 2 to rotate when it rotates, or the support structure 2 can drive the target component to rotate when it rotates. During the synchronous rotation process, the support structure 2 can maintain a tight connection with the target component, thereby providing stable support for the target component during rotation.

[0027] In an optional embodiment, the inner wall of the limiting channel 21 is not adapted to the shape of the target component, but its dimensions in at least one direction are similar to those of the target component, for example... Figure 1 and Figure 2 As shown, the cross-sectional shape of the limiting channel 21 is rectangular (the upper notch is the first opening 22), and the cross-sectional shape of the target component is H-shaped. Figure 1 In the horizontal direction shown, the size of the limiting channel 21 is close to the size of the target component, so that the limiting channel 21 can engage the target component. During synchronous rotation, the two sides and one bottom surface of the limiting channel 21 can apply support force to the target component respectively, playing a role in continuous support during rotation.

[0028] Functionally, the support structure 2 is similar to a clamp, used to engage with target components such as columns. The cross-sectional shape of the limiting channel 21 can be circular, rectangular, triangular, polygonal, etc.

[0029] For target components with non-circular cross-sectional shapes such as rectangles, triangles, and polygons, the cross-sectional shape of the limiting channel 21 can be set to a corresponding rectangle, triangle, or polygon of similar size. The inner wall of the limiting channel 21 is slightly larger than the outer wall of the target component so that the target component can pass through the limiting channel 21. Through the interlocking between the inner wall of the limiting channel 21 and the outer wall of the target component, the supporting structure 2 and the target component can remain relatively stationary during rotation, and there is little or no relative slippage between the supporting structure 2 and the target component.

[0030] For target components with irregular cross-sectional shapes such as H-shaped or channel-shaped, the cross-sectional shape of the limiting channel 21 can be set to be close to the dimension of the target component in one direction. For example, for a railway sound barrier column with an H-shaped cross-section, the corresponding limiting channel 21 has sides and a bottom surface, and the H-beam is placed between two opposite sides, with the spacing between the two sides corresponding to the width or height of the H-beam. To facilitate insertion and removal from the side of the limiting channel 21, the cross-section of the limiting channel 21 can be designed as a rectangle that can hold the H-beam. Figure 1 As shown, the inner wall of the limiting channel 21 is slightly larger than the size of the H-beam. The inner wall (including the side and bottom) of the limiting channel 21 is in contact with the outer surface and end face of the flange of the H-beam, so that the supporting structure 2 can apply a supporting force to the H-beam to overcome the weight of the H-beam. When the H-beam rotates relative to the base 1, the supporting structure 2 can rotate with the H-beam relative to the base 1, or when the supporting structure 2 rotates relative to the base 1, the H-beam can rotate with the supporting structure 2 relative to the base 1.

[0031] The support rotation device described in this embodiment, through the rotating base 1 and support structure 2, can effectively solve the problem of difficulty in supporting non-circular cross-section columns during rotation, and can achieve continuous and stable support for non-circular cross-section columns.

[0032] For a target component with a circular cross-section, due to the high symmetry of the circle, it is only necessary to open a circular channel or arc-shaped groove on the base 1 so that the target component can rotate relative to the base 1 within the circular channel or arc-shaped groove, thus achieving stable support during the rotation of the target component. However, this connection method has the problem of frequent friction between the target component and the base 1, which may cause wear or damage to the target component. The frictional resistance between the contact surfaces will also increase the difficulty of rotating the target component. Therefore, the cross-sectional shape of the limiting channel 21 can be set to a circle with a size similar to that of the target component. After the target component is inserted into the limiting channel 21, a fixing component is installed between the target component and the support structure 2 to prevent relative sliding between the target component and the support structure 2, so that the support structure 2 rotates synchronously with the target component relative to the base 1, thereby reducing the wear of the target component.

[0033] In an optional embodiment, the support structure 2 rotates relative to the base 1 around the first rotating shaft 4. The first rotating shaft 4 is parallel or approximately parallel to the longitudinal direction of the limiting channel 21. The longitudinal direction of the limiting channel 21 is the length direction of the target component passing through the limiting channel 21, so that the first rotating shaft 4 is parallel or approximately parallel to the length direction of the target component, so as to adapt to the target component rotating around the length direction.

[0034] To facilitate the description of this solution, combined with Figure 5 and Figure 9 Define the direction parallel to the first axis of rotation 4 as the first direction, and define a second direction and a third direction that are perpendicular to each other, both of which are perpendicular to the first direction.

[0035] In some embodiments, the base 1 is provided with a raceway 3, which is located on the outside of the support structure 2 and rotates in conjunction with the support structure 2.

[0036] Furthermore, the support structure 2 has an arc-shaped sidewall, the projection of which in the first direction is an arc. The raceway 3 includes at least three rotating members 31, which are capable of rotating relative to the base 1. Several rotating members 31 are arranged circumferentially along the arc-shaped sidewall of the support structure 2, and at least three rotating members 31 are distributed in different directions of the support structure 2 to restrict the translation of the support structure 2 in a plane perpendicular to the first direction. The arrangement of the rotating members 31 along the arc-shaped sidewall of the support structure 2 does not restrict the rotation of the support structure 2 in a plane perpendicular to the first direction. Setting the center of the arc-shaped sidewall on the first rotating shaft 4 allows the support structure 2 to rotate relative to the base 1 around the first rotating shaft 4. The rotation axis of the rotating member 31 is configured to be parallel or approximately parallel to the first rotating shaft 4, allowing the rotating member 31 to roll relative to the arc-shaped sidewall of the support structure 2, thereby reducing the frictional resistance when the support structure 2 rotates relative to the base 1.

[0037] In some embodiments, the base 1 includes a first component 11 and a second component 12 disposed opposite to each other, with a gap between the first component 11 and the second component 12, and a support structure 2 disposed in the gap. The size of the gap along the first direction can be similar to the size of the support structure 2 along the first direction, so that the first component 11 and the second component 12 can restrict the translation of the support structure 2 in the first direction, as well as its rotation about the second direction and the third direction.

[0038] Those skilled in the art will understand that an object has six degrees of freedom in three-dimensional space: translational degrees of freedom along the X, Y, and Z axes, and rotational degrees of freedom about the X, Y, and Z axes. Through the cooperation of the base 1 and several rotating components 31, five degrees of freedom of the supporting structure 2 relative to the base 1 can be restricted, leaving only the rotational degree of freedom of the supporting structure 2 relative to the base 1 about the first direction. This allows the supporting structure 2 to rotate only about the first axis of rotation 4 relative to the base 1. Of course, based on installation errors and rotational requirements, the base 1 and the several rotating components 31 do not absolutely restrict the other five degrees of freedom, but can allow for minor movements relative to the base 1.

[0039] In an optional embodiment, the rotating component 31 includes a rolling bearing 312 and a connecting rod 311. The connecting rod 311 connects the first component 11 and the second component 12. The rolling bearing 312 is sleeved on the connecting rod 311 and located in the space between the first component 11 and the second component 12. All rolling bearings 312 are arranged around the first rotating shaft 4. Specifically, the first component 11 and the second component 12 are connected by a screw. The connecting rod 311 is the shank of the screw. A nut and a bolt are connected to the connecting rod 311. The nut and bolt are located on the opposite sides of the first component 11 and the second component 12, respectively.

[0040] In an optional embodiment, the first rotating shaft 4 of the support structure 2 passes through the limiting channel 21. In some application scenarios, the purpose of rotating the target component is to change the orientation of its sidewall in space. From the perspective of saving space, it is best to keep the target component in the position before rotation after rotation, that is, the target component should preferably rotate around its cross-sectional center. In this embodiment, the cross-sectional center of the target component is approximately the cross-sectional center of the limiting channel 21, that is, the first rotating shaft 4 is preferably arranged at the cross-sectional center of the limiting channel 21. The limiting effect of the rotating component 31 on the support structure 2 in this embodiment is on the sidewall of the support structure 2, without occupying the central area of ​​the support structure 2. The area on the support structure 2 passing through the first rotating shaft 4 can be left to open the limiting channel 21. Therefore, by using the base 1 and the rotating component 31 described in this embodiment to limit the support structure 2, the target component can rotate around its central axis, reducing the space occupied by the target component during rotation.

[0041] In some embodiments, to accommodate target components of different lengths, the supporting rotation device described in this embodiment is used to support the middle part of the target component. That is, both ends of the target component can extend out of the supporting rotation device on both sides in the first direction. Therefore, the base 1 is provided with a receiving channel 13 corresponding to the limiting channel 21. The limiting channel 21 is located in the receiving channel 13. Both the limiting channel 21 and the receiving channel 13 are used for the target component to pass through.

[0042] In an optional embodiment, the cross-section of the accommodating channel 13 is larger than the cross-section of the limiting channel 21, in order to accommodate the rotation of the target component around the first rotating axis 4, combined with Figure 3 , Figure 6 , Figure 7 and Figure 8 The cross-section of the receiving channel 13 is the same as or similar to the rotation surface formed by the rotation of the target component, so that the target component passing through the limiting channel 21 can rotate 360°. Furthermore, considering that the cross-sectional shape of the limiting channel 21 is adapted to the shape of the target component, the cross-section of the receiving channel 13 can be the same as or similar to the rotation surface formed by the rotation of the limiting channel 21 around the first rotating axis 4. At this time, the target component passing through the limiting channel 21 can still rotate 360°.

[0043] Combination Figure 2 and Figure 3 In some embodiments, to facilitate the placement of the target component into the limiting channel 21 and the receiving channel 13, the support structure 2 is provided with a first opening 22 connecting the limiting channel 21 and the outside, and the base 1 is provided with a second opening 14 connecting the receiving channel 13 and the outside. By rotating the support structure 2 so that the projections of the first opening 22 and the second opening 14 in the first direction coincide, the target component can be placed into the limiting channel 21 and the receiving channel 13 from the first opening 22 and the second opening 14. Figure 1 As shown, it is not necessary to insert the limiting channel 21 from the end of the target component.

[0044] Combination Figure 2 The first opening 22 is connected to the limiting channel 21, and the two form a support limiting groove with open ends. That is to say, according to their different functions, the spatial area of ​​the support limiting groove can be divided into the limiting channel 21 and the first opening 22; combined with Figure 3 The second opening 14 is connected to the receiving channel 13, and the two form a receiving groove with open ends. Depending on their different functions, the spatial area of ​​the receiving groove can be divided into the receiving channel 13 and the second opening 14.

[0045] For H-beams, another advantage of setting the cross-section of the limiting channel 21 to a rectangle is that it makes it easier to insert the middle part of the H-beam into the limiting channel 21 from the side of the first opening 22.

[0046] Another function of configuring the cross-section of the accommodating channel 13 to be the same as or similar to the surface of revolution of the target component is that: Figure 7 As shown, when the support structure 2 rotates to the point where the first opening 22 faces downward, the sidewall of the receiving channel 13 can replace the support structure 2 to apply a supporting force to the target component, thereby maintaining stable support throughout the rotation of the target component.

[0047] In one embodiment, the base 1 is provided with seven rotating members 31, one of which is located on the side of the receiving channel 13 away from the second opening 14, i.e., as shown in the figure. Figure 3 Below, the remaining six rotating components 31 are symmetrically arranged on both sides of the base 1. The second opening 14 is located above the base 1, without any rotating components 31.

[0048] Combination Figure 1 and Figure 5 In some embodiments, the base 1 includes two clamping plates that are opposite to each other and spaced apart. The two clamping plates are also the first component 11 and the second component 12 mentioned above. The support structure 2 is a limiting plate disposed between the two clamping plates. Both the clamping plates and the limiting plate can be made of steel plates and have a certain thickness. The limiting plate has an arc-shaped sidewall. At least three rolling bearings 312 are rotatably connected between the two clamping plates. The rolling bearings 312 can be sleeved on the screw used to connect the two clamping plates. All rolling bearings 312 are arranged circumferentially along the arc-shaped sidewall of the limiting plate to restrict the translation of the limiting plate in a plane perpendicular to the first direction and to enable the limiting plate to rotate relative to the clamping plates. A supporting limiting groove is provided in the middle of the limiting plate. The supporting limiting groove can be engaged with the target component. A receiving groove is provided in the middle of the clamping plate. The cross-sectional shape of the receiving groove is adapted to the rotation surface formed by the rotation of the target component.

[0049] Combination Figure 9 In a second aspect, this utility model embodiment provides a support rotation system, including a column 5 and a support rotation device as described above, wherein the column 5 passes through the limiting channel 21.

[0050] Column 5, also known as the target component mentioned above, can be a railway sound barrier column, which is usually made of H-beams.

[0051] In some embodiments, the support rotation system further includes a base 7 and a rotation drive mechanism. The base 1 is fixedly connected to the base 7. The rotation drive mechanism is used to drive the column 5 to rotate relative to the base 1. When the column 5 rotates relative to the base 1, the support structure 2 follows the column 5 to rotate relative to the base 1. The rotation drive mechanism may include a servo motor and a rotary table 71 disposed on the base 7. One end of the column 5 is fixedly connected to the rotary table 71. The support rotation device is supported at the other end or middle of the column 5. The servo motor is used to drive the rotary table 71 to rotate.

[0052] In this embodiment, a specific application scenario of the supporting rotation system is a welding device for the column and base plate, which serves to support the rotating column 5. Specifically, the welding device for the column and base plate includes a base 7, a rotary table 71 mounted on the base 7, and a supporting rotation device spaced apart from the rotary table 71. The base 1 of the supporting rotation device is fixedly connected to the base 7. A servo motor in the rotation drive mechanism drives the rotary table 71 to rotate, and the rotation axis of the rotary table 71 coincides with the first rotation axis 4. Optional applications include... In this method, the column 5 and the base plate 6 are first spot-welded for initial fixation. Then, the base plate 6 is fixed on the rotary table 71, and the middle part of the column is supported on the support rotation device. The rotary table 71 is driven to rotate by the rotation drive mechanism to drive the base plate 6 and the column to rotate, so that the connection side to be welded faces upward. Then, manual or welding robot can be used to fix the connection between the column and the base plate 6. After the welding on this side is completed, the rotary table 71 is driven to rotate again to make the other connection sides to be welded face upward. The above steps are repeated.

[0053] In an optional embodiment, molten iron is used to weld the joint between the column 5 and the base plate 6. To ensure that the molten iron is evenly distributed on the side wall of the column 5 and the surface of the base plate 6, the angle between the column 5 and the horizontal plane is 40°-50°, or even 45°. To reduce the flow of molten iron, the length direction of the joint between the column 5 and the base plate 6 is horizontal. For columns 5 of different specifications and shapes, different supporting rotation devices can be selected to support the column 5.

[0054] In an optional embodiment, a welding robot is used to spray molten iron onto the joint between the column 5 and the base plate 6. Exemplarily, the welding robot includes components such as a welding arm, a welding torch, a carbon dioxide cylinder, and a MIG / MAG welding machine. The welding arm is used to move the welding torch, the MIG / MAG welding machine is used to supply welding material to the welding torch, and the carbon dioxide cylinder is connected to the welding torch through a gas pipe to output carbon dioxide as a protective gas, which isolates the air and protects the weld pool. Furthermore, the movement of the welding arm, the opening and closing of the MIG / MAG welding machine, and the rotation of the rotary table 71 are all controlled by automated programming to achieve automated welding and improve welding efficiency.

[0055] In an optional embodiment, the platform 7 is hinged to the ground or base, allowing the platform 7 to rotate relative to the ground or base to transition from a first state to a second state. In the first state, the column 5 mounted on the platform 7 is horizontal, facilitating the placement or removal of the column 5 from the platform 7. In the second state, the column 5 mounted on the platform 7 is inclined relative to the horizontal plane, with an inclination angle of 40°-50°, or more specifically 45°, allowing the molten iron to be evenly distributed on the side wall of the column 5 and the surface of the base plate 6. To enable the platform 7 to switch between the first and second states, a hydraulic telescopic rod 72 is also provided for pushing and pulling the platform 7 to rotate.

[0056] In one alternative approach, robotic welding is used to address welding defects such as slag inclusions, porosity, undercut, and poor appearance quality found in traditional manual welding, thereby improving the weld inspection pass rate and enhancing efficiency.

[0057] The support rotation device described in this utility model can effectively solve the support problem during the rotation of the column 5, reduce the torque exerted by the column 5 on the base plate 6, meet the requirement of synchronous rotation of the column 5 with the base plate 6, and reduce friction between the column 5 and the support device. The support rotation device described in this embodiment is easy to operate, can be locked to columns 5 with non-circular cross-sections, and features stability, reliability, flexible replacement, and compatibility with welding operations of H-beams of different sizes.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
