Description

Technical Field

[0001] This invention relates to the technical field of flipping machines, and in particular to a device and equipment for flipping large-size heavy-duty plate structural components in place. Background Technology

[0002] Existing flipping mechanisms all have a fixed flipping axis. Based on the nature of the flipping axis, flipping mechanisms can be specifically divided into those that use the symmetry axis of a symmetrical workpiece as the flipping axis and those that do not. However, when large, heavy-duty plate structures need to be flipped, these structures may not have a symmetry axis at all. Even for large, heavy-duty plate structures with a symmetry axis, flipping mechanisms using the workpiece's symmetry axis as the flipping axis cannot meet the load requirements. Furthermore, when a heavy-duty flipping mechanism that does not use the workpiece's symmetry axis as the flipping axis flips a large, heavy-duty plate structure 180°, the large... Heavy-duty plate structural components need to rotate around the fixed rotation axis of the flipping mechanism and cannot be flipped within the original space occupied by the structural components. This results in the existing heavy-duty flipping mechanism occupying at least twice the space occupied by the large-size heavy-duty plate structural components. In addition, the heavy-duty flipping mechanism occupies a large space and is also large in size. Therefore, the existing heavy-duty flipping mechanism is generally not suitable for installation in the limited space next to the processing station of large-size heavy-duty plate structural components. Moreover, when there are many processing stations for large-size heavy-duty plate structural components, the cost of equipping each processing station with a heavy-duty flipping mechanism is too high and not feasible.

[0003] In summary, existing technologies suffer from the following problems: they cannot be rotated in place when large-sized heavy plate structural components are being rotated; the installation space is large; and the rotation efficiency for large-sized heavy plate structural components is low. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a device and equipment for in-situ flipping of large-size heavy plate structural components, so as to alleviate the technical problem in the prior art that large-size heavy plate structural components cannot be flipped in-situ and occupy a large space.

[0005] In a first aspect, a device for in-situ flipping of a large-size heavy-duty plate structure includes a pallet, a base, a drive mechanism, and a column. The bottom of the column is provided with a push rod. The column is perpendicular to the plane of the base. A vertical guide rail is provided in the parallel direction of the column. A horizontal guide rail is installed on the base. The drive mechanism is mechanically connected to end B of the pallet.

[0006] During the flipping process, when the tray is perpendicular to the base, the lower push rod extends outward and pushes the tray.

[0007] The drive mechanism continues to drive the B end of the pallet to move downward along the vertical guide rail, and the A end of the pallet moves along the horizontal guide rail to flip the large-sized heavy plate structure component to be flipped.

[0008] One possible approach is that, during the flipping process, end B of the tray is flipped upwards with end A of the tray as the axis until the tray is perpendicular to the base.

[0009] One possible approach is to also include an upper push rod located at the top of the column;

[0010] During the reset process, when the tray is perpendicular to the base, the drive mechanism drives end B of the tray to rotate downwards around end A of the tray until the tray comes into contact with the base.

[0011] One possible approach is that, during the reset process, the drive mechanism causes end B of the tray to move upward along the vertical guide rail, while end A of the tray moves along the horizontal guide rail until the tray is perpendicular to the base.

[0012] One possible approach is that the pallet is provided with rollers at the four corners, and there are two vertical guide rails and two horizontal guide rails. The vertical guide rails intersect with the horizontal guide rails on the corresponding sides, so that the pallet can move on the vertical guide rails and / or the horizontal guide rails by means of the rollers.

[0013] A stop block is provided at the end of the horizontal guide rail away from the vertical guide rail, and a locking mechanism is provided at the end of the vertical guide rail closer to the horizontal guide rail.

[0014] One possible approach is that the base is equipped with a lifting mechanism for supporting the large, heavy-duty plate structure after it has been flipped over.

[0015] One possible approach is that the pallet is equipped with clamps for holding large, heavy-duty plate structural components of different sizes on the pallet.

[0016] One possible approach is that the drive mechanism includes a worm gear motor, the output shaft of which is connected to a rope pulley, the rope pulley being provided with a steel wire rope, and the B end of the support plate being provided with a mounting shaft, the free end of which is connected to the mounting shaft, the mounting shaft being located on both sides of the B end of the support plate.

[0017] In a second aspect, the present invention provides an in-situ turning device for large-size heavy-duty plate structure components, characterized in that it includes a rail flatcar and an in-situ turning device for large-size heavy-duty plate structure components as described in any one of the first aspects, wherein the in-situ turning device for large-size heavy-duty plate structure components is mounted on the rail flatcar.

[0018] The embodiments of this invention bring the following beneficial effects: A device and equipment for in-situ flipping of large-size heavy-duty plate structural components, relating to the technical field of flipping machines, includes a pallet and base, a drive mechanism and a column. A push rod is provided at the bottom of the column, and the column is perpendicular to the plane of the base. A vertical guide rail is provided parallel to the column, and a horizontal guide rail is installed on the base. The drive mechanism is mechanically connected to end B of the pallet. During the flipping process, the push rod extends outward and pushes the pallet; the drive mechanism continues to drive end B of the pallet downward along the vertical guide rail, and end A of the pallet moves along the horizontal guide rail to flip the large-size heavy-duty plate structural component to be flipped. This invention can alleviate the technical problem in the prior art that large-size heavy-duty plate structural components cannot be flipped in situ, resulting in a large space occupation.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Currently, all existing flipping mechanisms have a fixed flipping axis. Based on the nature of the flipping axis, flipping mechanisms can be specifically divided into those that use the symmetry axis of the symmetrical workpiece as the flipping axis and those that do not. However, when large-size heavy plate structural components need to be flipped, these components may not have a symmetry axis at all. Even for large-size heavy plate structural components with a symmetry axis, flipping mechanisms using the workpiece's symmetry axis as the flipping axis cannot meet the load requirements. Furthermore, when a heavy-duty flipping mechanism that does not use the workpiece's symmetry axis as the flipping axis flips a large-size heavy plate structural component 180°, the load becomes unsatisfactory. Heavy-duty plate structural components need to rotate around the fixed rotation axis of the flipping mechanism and cannot be flipped within the original space occupied by the component. This results in the existing heavy-duty flipping mechanism occupying at least twice the space occupied by the large-size heavy-duty plate structural component. In addition, the heavy-duty flipping mechanism has a large space occupation and volume. Therefore, the existing heavy-duty flipping mechanism is generally not suitable for installation in the limited space next to the processing station of large-size heavy-duty plate structural components. Moreover, when there are many processing stations for large-size heavy-duty plate structural components, the cost of equipping each processing station with a heavy-duty flipping mechanism is too high and not feasible.

[0033] To facilitate understanding of this embodiment, a detailed description of an in-situ flipping device for large-size heavy-duty plate structure components disclosed in this embodiment of the invention will be provided first.

[0034] The embodiments provided by this invention can be applied to the flipping of large-size heavy-duty plate structural components. Large-size heavy-duty plate structural components are usually used as key installation components in mechanical equipment. The large-size heavy-duty plate structural components mentioned in the following embodiments of this invention mainly refer to plates with high-precision mating surfaces that need to be flipped, including but not limited to the following types of components: chassis of heavy vehicles and car floor of wind turbines.

[0035] Example 1:

[0036] The present invention provides an exemplary embodiment of a device for in-situ flipping of a large-size heavy-duty plate structure, comprising a support plate 13 and a base 1, a drive mechanism and a column 7, wherein the bottom of the column 7 is provided with a push rod 16, the column 7 is perpendicular to the plane of the base 1, a vertical guide rail 9 is provided in the parallel direction of the column 7, the base 1 is equipped with a horizontal guide rail 17, and the drive mechanism is mechanically connected to end B of the support plate 13.

[0037] Initial position of this embodiment Figure 1 As shown, end B of the tray 13 is the end of the tray 13 away from the column 7 at this time, and end A of the tray 13 is the end of the tray 13 close to the column 7 at this time.

[0038] Combination Figure 2 as well as Figure 3 The drive mechanism drives the B end of the tray 13 to rotate upward with the A end of the tray 13 as the axis until the tray 13 is perpendicular to the base 1, and the lower push rod 16 extends outward and pushes the tray 13.

[0039] Based on existing technology, the push rod 16 can be driven to extend and retract electrically or by other means;

[0040] like Figure 4 As shown, the drive mechanism continues to drive the B end of the pallet 13 to move downward along the vertical guide rail 9, and the A end of the pallet 13 moves along the horizontal guide rail 17 to flip the large-size heavy plate structure 11 to be flipped.

[0041] It should be understood that when the B end of the pallet 13 moves downward along the vertical guide rail, the A end of the pallet 13 moves away from the column 7 under the action of gravity due to the pushing force of the lower push rod 16, thus completing the flipping. Here, the lower push rod 16 plays the role of specifying the direction of movement of the pallet 13 so that the pallet 13 can be flipped.

[0042] At this time, end B of the tray 13 is the end of the tray 13 closer to the column 7, and end A of the tray 13 is the end of the tray 13 away from the column 7.

[0043] Through the embodiments provided by the present invention, it is possible to flip the large-size heavy-duty plate structure component 11, and then process the other side of the large-size heavy-duty plate structure component 11. The state after flipping is as follows: Figure 5 As shown;

[0044] In this application, various methods such as clamping and embedding can be used to fix the large-size heavy plate structure 11 during the flipping process.

[0045] The application specifically employs a clamping method. Accordingly, based on the aforementioned embodiments, it also includes a clamp 12, which is used to clamp large-sized heavy-duty plate structural components 11 of different specifications to be flipped, in conjunction with... Figure 5 as well as Figure 6 After the large-size heavy plate structure component 11 is flipped over, the base 1 is provided with the lifting mechanism 18 to support the large-size heavy plate structure component 11 and release the clamps.

[0046] Furthermore, the drive mechanism continues to drive the B end of the pallet 13 to move upward along the vertical guide rail 9 until the pallet 13 is perpendicular to the base 1. During this period, the lifting mechanism 18 is used to support the large-size heavy plate structure 11 after it has been flipped. Then, a crane is used to lift the large-size heavy plate structure 11 after it has been flipped for further processing.

[0047] It should be understood that at this time, when the large-size heavy-duty plate structure 11 is perpendicular to the base 1 and the support plate 13 is perpendicular to the base 1, there are no obstructions above the large-size heavy-duty plate structure 11, such as... Figure 6 As shown;

[0048] This allows the large, heavy-duty plate structure component 11 to be lifted using a crane after being flipped over, and the other side of the large, heavy-duty plate structure component 11 to be processed, such as... Figure 7 As shown. Further integration Figure 7 To achieve the reset of the support plate 13, in this embodiment, an upper push rod 5 is provided on the upper part of the column 7. The upper push rod 5 extends outward and pushes the B end of the support plate 13. The drive mechanism drives the B end of the support plate 13 to rotate downward about the A end of the support plate 13 as the axis, until the support plate 13 abuts against the base 1, and the final state is as follows. Figure 8 As shown.

[0049] It should be understood that under the action of the upper push rod 5, the B end of the tray 13 moves away from the column 7. When the B end of the tray 13 rotates downward about the A end of the tray 13, the B end of the tray 13 moves toward one side of the base 1, thus completing the reset. Here, the upper push rod 5 plays the role of specifying the direction of movement of the tray 13 so that the tray 13 is reset.

[0050] Combination Figures 1 to 8 In order to enable the pallet 13 to move on the guide rail, rollers 3 are provided at the four corners of the pallet 13. There are two vertical guide rails 9 and two horizontal guide rails 17. The vertical guide rail 9 intersects with the horizontal guide rail 17 on the corresponding side, so that the pallet 13 can move on the vertical guide rail 9 and / or the horizontal guide rail 17 by means of the rollers 3.

[0051] It should be understood that the distance between the two rollers 3 on the left and right sides of the pallet 13 is the distance of the horizontal guide rail 17;

[0052] Based on the above embodiments, in the embodiments provided by the present invention, in order to prevent the pallet 13 from sliding in a stationary state, a stop block 2 is provided at the end of the horizontal guide rail 17 away from the vertical guide rail 9, and a locking mechanism 10 is provided at the end of the vertical guide rail 9 close to the horizontal guide rail 17.

[0053] By using the stop block 2 of the horizontal guide rail 17 and the locking mechanism 10 of the vertical guide rail 9, the pallet 13 can be locked when it is laid flat, preventing the pallet 13 from sliding.

[0054] For example, the two vertical guide rails 9 are placed in parallel, and the two horizontal guide rails 17 are placed in parallel. When the support plate 13 moves to be perpendicular to the base 1, the plane where the support plate 13 is located is parallel to the plane where the vertical guide rails 9 are located, and the upper push rod 5 and the lower push rod 16 are perpendicular to the plane formed by the two vertical guide rails 9.

[0055] This enables the large-size heavy-duty plate structure component 11 to be flipped in place.

[0056] Combination Figures 1 to 8 Based on the aforementioned embodiments, in order to make this embodiment more convenient to carry and transport, the column 7 is rotatably connected to the base 1, and the vertical guide rail 9 is detachably connected to the base 1.

[0057] For example, the column 7 and the base 1 are hinged, one end of the vertical guide rail 9 is provided with a boss, one end of the horizontal guide rail 17 is provided with a slot, the boss is provided with a through hole, the boss and the slot are engaged, and a pin is inserted into the through hole.

[0058] By inserting a pin inside the through hole, the vertical guide rail 9 and the horizontal guide rail 17 can be positioned.

[0059] The other end of the vertical guide rail 9 is hinged to the column 7 via a pin.

[0060] Based on the aforementioned embodiments, in order to enable the drive mechanism to drive the pallet 13 to move, one possible implementation is that the drive mechanism includes a worm gear motor 14, the output shaft of which is connected to a rope wheel 6, a steel wire rope 4 is provided on the rope wheel 6, a mounting shaft is provided at the B end of the pallet 13, the free end of the steel wire rope 4 is connected to the mounting shaft, and the mounting shaft is located on both sides of the B end of the pallet 13.

[0061] Based on the above embodiments, this application also provides a support rod 15 and a connecting rod 8. The connecting rod 8 is located between the column 7 and the vertical guide rail 9, and the support rod 15 is located between the base 1 and the column 7. The wire rope 4, the connecting rod 8, the upper push rod 5, the lower push rod 16, and the support rod 15 are respectively arranged in four parallel and non-overlapping planes, so that there is no interference between the wire rope 4, the push rod, the support rod 15, and the connecting rod 8.

[0062] This application has the following advantages:

[0063] 1) The flipping device proposed in this invention is used to flip large-size heavy plate structure components in place, thus having the advantages of compact structure and small size. At the same time, it can meet the requirements of large load and can complete the 180° flipping work in place on the track flat car next to the processing station, saving factory operating space and reducing the construction and use costs of enterprise factory buildings.

[0064] 2) The clamp of the present invention can preferably be fixed in position, and can adapt to the clamping of workpieces of different specifications;

[0065] Example 2:

[0066] Combination Figures 1 to 8 Based on Embodiment 1, Embodiment 2 of the present invention provides an exemplary embodiment of a device for in-situ flipping of large-size heavy-duty plate structure components, including a rail flatcar 19 and an in-situ flipping device for large-size heavy-duty plate structure components, wherein the in-situ flipping device for large-size heavy-duty plate structure components is installed on the rail flatcar 19.

[0067] By using a rail flatcar, a single tilting device can meet the needs of multiple workstations, improving processing efficiency and reducing equipment costs for enterprises.

[0068] Example 3:

[0069] Embodiment 3 of the present invention provides an exemplary method for in-situ flipping of a large-size heavy-duty plate structure component. The large-size heavy-duty plate structure component to be flipped is mounted on the support plate, and the method specifically includes the following steps:

[0070] The drive mechanism drives the B end of the tray to move, so that the B end of the tray rotates upward with the A end of the tray as the axis, until the tray is perpendicular to the base. The B end of the tray is the end of the tray away from the column, and the A end of the tray is the end of the tray close to the column.

[0071] The push rod located at the bottom of the column extends outward, pushing end A of the tray to move along the horizontal guide rail;

[0072] The drive mechanism drives the B end of the pallet to move, so that the B end of the pallet moves downward along the vertical guide rail, and drives the A end of the pallet to move along the horizontal guide rail toward the end away from the column, until the pallet abuts against the base, so as to flip the large-sized heavy plate structure.

[0073] One possible implementation is that the drive mechanism drives the B end of the pallet to move, causing the B end of the pallet to move downward along the vertical guide rail, and driving the A end of the pallet to move along the horizontal guide rail toward the end away from the column, until the pallet abuts against the base, after the step of flipping the large-size heavy plate structure, the method includes:

[0074] The large, heavy-duty plate structure component, after being flipped over, is moved to its designated position.

[0075] One possible implementation is that, after moving the flipped, large-sized heavy-duty plate structure to a predetermined position, the method further includes:

[0076] The tray is reset.

[0078] Use the lifting mechanism to support the large, heavy-duty plate structure component, and then release the clamps;

[0079] The drive mechanism drives the B end of the tray to move, so that the B end of the tray moves upward along the vertical guide rail, and drives the A end of the tray to move along the horizontal guide rail toward the end closer to the column, until the tray is perpendicular to the base.

[0080] A crane is used to lift and move the large, heavy plate structure components, which have been translated, to the designated location.

[0081] One possible implementation is that the tray is perpendicular to the base, and the step of resetting the tray includes:

[0082] The upper push rod located at the top of the column extends outward to push the B end of the tray to move;

[0083] The drive mechanism drives the B end of the tray to move, so that the B end of the tray flips downward with the A end of the tray as the axis, until the tray abuts against the base.

[0084] Based on Embodiment 2, one possible implementation is that the driving device includes a worm gear motor connected to a rope wheel, the rope wheel being wound with a steel wire rope, the free end of the steel wire rope being connected to the mounting shaft at end B of the pallet, so that the driving mechanism drives end B of the pallet to move, and rollers are provided at the four corners of the pallet, the pallet moving along the vertical guide rail and / or the horizontal guide rail using the rollers.

[0085] The method described herein can be followed according to Example 1, and will not be repeated here.
