Description

Technical Field

[0001] This invention belongs to the field of tooling and auxiliary equipment technology, and specifically relates to a flipping device. Background Technology

[0002] Some workpieces need to be flipped from a horizontal to a vertical position during production or maintenance. For example, large plate heat exchangers need to be flipped using flipping fixtures during production to facilitate the inspection of all welds around the plate heat exchanger.

[0003] Traditional flipping fixtures include a rotatable flipping seat, which typically comprises a main support frame for supporting the bottom of the workpiece and a side support frame for supporting the sides of the workpiece. The flipping seat is mounted on a machine frame via a rotating base. During operation, an external force is applied to the flipping seat, causing it to rotate the workpiece around the rotating base as a fulcrum.

[0004] However, in traditional flipping fixtures, as the workpiece flipping angle increases, the workpiece's center of gravity flips from one side of the fulcrum to the other side, which can easily cause the workpiece to tip over toward the other side of the fulcrum. Summary of the Invention

[0005] The present invention provides a flipping device that can control the workpiece to achieve two-stage flipping, so as to improve the problem that the workpiece is prone to tipping over due to the change of center of gravity during the flipping process.

[0006] An embodiment of the present invention provides a flipping device, including a first flipping seat that is rotatably disposed, the first flipping seat including a main support frame and a side support frame disposed at one end of the main support frame; and a second flipping seat having a flipping arm; the first flipping seat is connected to one end of the flipping arm through a first rotating seat, and the other end of the flipping arm is provided with a second rotating seat;

[0007] The first flipping seat achieves a first-stage flipping relative to the flipping arm with the first rotating seat as the fulcrum; during the first-stage flipping process, the first flipping seat and the second flipping seat form a limiting structure in the flipping direction, so that the first flipping seat and the second flipping seat simultaneously achieve a second-stage flipping with the second rotating seat as the fulcrum.

[0008] In some embodiments, the first rotating seat is disposed at the junction of the main support frame and the side support frame;

[0009] The second flipping seat also includes a support arm disposed on the flipping arm, the support arm being used to abut against the side support frame during the first-stage flipping process, so that the limiting structure is formed between the first-stage flipping seat and the second-stage flipping seat.

[0010] In some embodiments, the distance L1 between the top of the support arm and the first rotating seat is less than or equal to the distance L2 between the top of the side support frame and the first rotating seat.

[0011] In some embodiments, the first rotating seat is disposed on the main support frame, and the first rotating seat and the end of the main support frame disposed on the side support frame are at a distance L3;

[0012] The first rotating seat is connected to the flipping arm via a support seat, such that the first rotating seat and the flipping arm are at a distance L4 in a direction perpendicular to the flipping arm;

[0013] The distance L3 between the first rotating seat and the end of the main support frame is greater than the distance L4 between the first rotating seat and the flipping arm, so that the limiting structure is formed between the first-stage flipping seat and the second-stage flipping seat.

[0014] In some embodiments, the first rotating seat is disposed on the main support frame, and there is a distance between the first rotating seat and the end of the main support frame on which the side support frame is disposed;

[0015] The first rotating seat is connected to the flipping arm through the support seat, such that there is a gap between the first rotating seat and the flipping arm in a direction perpendicular to the flipping arm;

[0016] The flipping arm is provided with a support arm to abut against the main support frame and / or the side support frame, so that the limiting structure is formed between the first-level flipping seat and the second-level flipping seat.

[0017] In some embodiments, the first rotating seat is connected to the flipping arm via a support seat, such that there is a gap between the first rotating seat and the flipping arm in a direction perpendicular to the flipping arm;

[0018] The flipping arm is provided with a support arm to abut against the side support frame, so that the limiting structure is formed between the first-stage flipping seat and the second-stage flipping seat.

[0019] In some embodiments, the tilting arm is connected to the frame via the second rotating seat, the frame is provided with a first buckle, and the main support frame is provided with a second buckle adapted to the first buckle; the first buckle and the second buckle are connected by ropes to limit the tilting angle.

[0020] In some embodiments, the frame is provided with a support frame to support the free end of the main support frame, such that the support frame, in conjunction with the first rotating seat, horizontally supports the main support frame.

[0021] In some embodiments, a buffer block is provided on the side support frame corresponding to the support arm.

[0022] In some embodiments, a maintenance platform is provided on the side of the side support frame away from the main support frame.

[0023] The flipping device of this invention can control the workpiece to achieve two-stage flipping. In the first-stage flipping process, the first flipping seat drives the workpiece to flip around the first rotating seat as a fulcrum. In the second-stage flipping process, the workpiece on the first flipping seat follows the second flipping seat and flips synchronously around the second rotating seat as a fulcrum. The fulcrum of the first-stage and second-stage flipping changes its support position as the workpiece flips, so that the center of gravity of the workpiece is always located on the same side of the fulcrum in the flipping direction, preventing the workpiece from tipping over from the other side of the fulcrum, thereby improving the problem of the workpiece easily tipping over due to the change of the center of gravity during the flipping process.

[0036] Example 1

[0037] like Figure 1-4 As shown, this embodiment provides a flipping device, which includes a frame 10, a second flipping seat mounted on the frame 10, and a first flipping seat mounted on the second flipping seat. The first flipping seat includes a main support frame 20 and a side support frame 21 located at one end of the main support frame 20. The main support frame 20 supports the bottom of the workpiece 90, and the side support frame 21 supports the side of the workpiece 90. Preferably, the entire first flipping seat is L-shaped. The second flipping seat includes a flipping arm 30. One end of the flipping arm 30 is connected to the first flipping seat via a first rotating seat 40, and the other end of the flipping arm 30 is connected to the frame 10 via a second rotating seat 41. In some embodiments, the flipping arm 30 can be mounted on the ground via the second rotating seat 41 as needed.

[0038] See details Figure 3 The first flipping seat is connected to the flipping arm 30 via the first rotating seat 40, enabling the first flipping seat to achieve a first-stage flipping relative to the flipping arm 30 with the first rotating seat 40 as the fulcrum; see details. Figure 4 The flipping arm 30 of the second flipping seat is connected to the frame 10 through the second rotating seat 41, so that the second flipping seat can achieve a second-level flipping relative to the frame 10 with the second rotating seat 41 as the fulcrum; during the first-level flipping process, the first flipping seat and the second flipping seat form a limiting structure in the flipping direction, so that the first flipping seat and the second flipping seat can flip synchronously during the second-level flipping process.

[0039] The working process of the flipping device in this embodiment is as follows: An external force is applied to the first flipping seat, causing the first flipping seat to drive the workpiece 90 to achieve a first-stage flipping with the first rotating seat 40 as the fulcrum. At this time, only the first flipping seat rotates, while the second flipping seat is stationary. When the workpiece 90 flips at a certain angle, the first flipping seat and the second flipping seat form a limiting structure in the flipping direction. The first flipping seat transmits the external force to the second flipping seat through the limiting structure, so that the workpiece 90 on the first flipping seat follows the second flipping seat and synchronously achieves a second-stage flipping with the second rotating seat 41 as the fulcrum. At this time, the first flipping seat and the second flipping seat remain relatively stationary, and the first flipping seat and the second flipping seat flip synchronously flip relative to the frame 10. After the second-stage flipping process is completed, the workpiece 90 can cause the second flipping seat and the first flipping seat to return to their original positions under its own gravity. When the second flipping seat has completed its return to its original position, the limiting structure formed by the first flipping seat and the second flipping seat can be automatically released, allowing the first flipping seat to flip back to its initial position.

[0040] Since the flipping device in this embodiment can control the workpiece 90 to achieve two-stage flipping, the fulcrum of the first-stage flipping and the second-stage flipping will change the support position as the workpiece 90 flips, so that the center of gravity of the workpiece 90 is always located on the same side of the fulcrum in the flipping direction, avoiding the workpiece 90 from tipping over from the other side of the fulcrum, thereby improving the problem that the workpiece 90 is prone to tipping over due to the change of the center of gravity during the flipping process.

[0041] The flipping device in this embodiment is preferably used in conjunction with a lifting device. The lifting device applies external force to the free end of the main support frame 20 only through the hook, and the flipping device can achieve two flips in sequence, namely the first-stage flip and the second-stage flip, without the need for an additional power mechanism. The operation is simple and convenient. Furthermore, in traditional flipping fixtures, the flipping seat has only one fixed fulcrum. Due to the problem that the existing flipping seat is prone to interference with the frame 10, the flipping angle of the workpiece 90 on the existing flipping seat does not exceed 90°. However, the flipping device in this embodiment can change the fulcrum, so that the flipping angle of the workpiece 90 can be greater than 90°, which can meet more flipping requirements. Some embodiments can set conventional power mechanisms such as motors and hydraulic cylinders for the first-stage flipping seat and the second-stage flipping seat respectively, so that the flipping device in this embodiment can achieve two-stage flipping.

[0042] See details Figure 2 In this embodiment, the first rotating seat 40 is located at the junction of the main support frame 20 and the side support frame 21. The flipping arm 30 is provided with a support arm 31, which is used to abut against the side support frame 21 during the first-stage flipping process. Specifically, the distance L1 between the top of the support arm 31 and the first rotating seat 40 is less than or equal to the distance L2 between the top of the side support frame 21 and the first rotating seat 40, ensuring that the first rotating seat forms a limiting structure with the side support frame 21 and the support arm 31 during the first-stage flipping process.

[0043] In this embodiment, the first rotating seat 40 is positioned at the junction of the main support frame 20 and the side support frame 21. The main support frame 20 is directly connected to the tilting arm 30 via the first rotating seat 40, allowing the first rotating seat 40 to tilt relative to the tilting arm 30 in a single stage. The main support frame 20 and the tilting arm 30 are approximately on the same plane, ensuring structural compactness. In this embodiment, the side support frame 21 abuts against the support arm 31 to form a limiting structure. The side support frame 21, the tilting arm 30, and the support arm 31 form a triangular structure, which helps improve the stability of the limiting structure. In this embodiment, the side support frame 21 is provided with a buffer block 22 corresponding to the support arm 31 to mitigate the impact load between the side support frame 21 and the support arm 31, thus helping to extend service life.

[0044] In this embodiment, the frame 10 is provided with a first buckle 50, and the main support frame 20 is provided with a second buckle 51 adapted to the first buckle 50. The first buckle 50 and the second buckle 51 are connected by a rope 52 to limit the flipping angle. By calculating the length of the rope 52, when the main support frame 20 flips too much relative to the frame 10, the rope 52 can pull the main support frame 20 in the opposite direction of flipping, thus preventing the workpiece 90 from tipping over in the flipping direction due to the excessive flipping angle.

[0045] In this embodiment, the frame 10 is preferably flat. A support frame 11 is provided on the frame 10 to support the free end of the main support frame 20, so that the support frame 11, in conjunction with the first rotating seat 40, horizontally supports the main support frame 20, facilitating the horizontal loading of the workpiece 90 onto the first tilting seat. The main support frame 20 is provided with conventional latches 60 and binding straps 61 to secure the workpiece 90 to the main support frame 20. The main support frame 20 is provided with a conventional first support pad 70 to support the bottom of the workpiece 90, and the side support frame 21 is provided with a conventional second support pad 71 to support one side of the workpiece 90. For some large workpieces 90, due to the large size of the main support frame 20 and the side support frame 21, a maintenance platform 80 is provided on the side of the side support frame 21 away from the main support frame 20 to provide space for operators to inspect the workpiece 90.

[0046] It should be noted that the rotating seat in this embodiment can be a conventional hinge or bearing seat to ensure that the interconnected parts can rotate relative to each other. Therefore, the structure of the first rotating seat 40 and the second rotating seat 41 will not be described in detail in this embodiment. In addition, since the center of gravity of the workpiece 90 is related to factors such as shape and size, the relevant dimensions of the first rotating seat 40 and the second rotating seat 41 will not be described in detail in this embodiment. It is sufficient to ensure that the center of gravity of the workpiece is always located on the same side of the corresponding fulcrum during the flipping process.

[0047] Example 2

[0048] See details Figure 5In this embodiment, the first rotating seat 40 is not placed at the junction of the main support frame 20 and the side support frame 21. Instead, the first rotating seat 40 is placed on the main support frame 20. The first rotating seat 40 and the main support frame 20 are located at the end of the side support frame 21 with a distance L3. The first rotating seat 40 is connected to the flipping arm 30 through the support seat 32, so that the first rotating seat 40 and the flipping arm 30 are located at a distance L4 in the direction perpendicular to the flipping arm 30, ensuring that the first flipping seat will not interfere with the flipping arm 30 during the first-stage flipping process.

[0049] In this embodiment, the distance L3 between the first rotating seat 40 and the end of the main support frame 20 is greater than the distance L4 between the first rotating seat 40 and the flipping arm 30, so that the end of the main support frame 20 can abut against the flipping arm 30 during the first-stage flipping process, thereby forming a limiting structure between the first flipping seat and the second flipping seat.

[0050] The working process of the flipping device in this embodiment is as follows: An external force is applied to the first flipping seat, causing the first flipping seat to drive the workpiece 90 to achieve a first-stage flip with the first rotating seat 40 as the fulcrum. At this time, only the first flipping seat rotates, while the second flipping seat is stationary. When the workpiece 90 flips at a certain angle, the corresponding end of the main support frame 20 abuts against the flipping arm 30, so that part of the main support frame 20, part of the support seat 32, and part of the flipping arm 30 form a triangular limiting structure. The first flipping seat transmits the external force to the second flipping seat through this limiting structure, so that the workpiece 90 on the first flipping seat follows the second flipping seat and synchronously achieves a second-stage flip with the second rotating seat 41 as the fulcrum. At this time, the first flipping seat and the second flipping seat remain relatively stationary, and the first flipping seat and the second flipping seat flip relative to the frame 10 at the same time.

[0051] Example 3

[0052] See details Figure 6 In this embodiment, the first rotating seat 40 is mounted on the main support frame 20, and there is a gap between the first rotating seat 40 and the end of the main support frame 20 where the side support frame 21 is mounted. The first rotating seat 40 is connected to the flipping arm 30 through the support seat 32, so that there is a gap between the first rotating seat 40 and the flipping arm 30 in the direction perpendicular to the flipping arm 30, ensuring that the first flipping seat will not interfere with the flipping arm 30 during the first-stage flipping process. The difference between this embodiment and embodiment two is that: in this embodiment, the flipping arm 30 is provided with a support arm 31 to abut against the main support frame 20 and / or the side support frame 21, so that a limiting structure is formed between the first-stage flipping seat and the second-stage flipping seat.

[0053] When the support arm 31 is only provided on the tilting arm 30 to abut against the main support frame 20, the distance L5 between the first rotating seat 40 and the end of the main support frame 20 where the side support frame 21 is located needs to be greater than or equal to the distance L6 between the first rotating seat 40 and the top of the support arm 31. Since the principle of using the support arm 31 in conjunction with the main support frame 20 or the side support frame 21 to form a limiting structure is the same as in Embodiment 1, the distance relationships between the support arm 31, the first rotating seat 40 and the main support frame 20 and / or the side support frame 21 that they cooperate with will not be described again in this embodiment.

[0054] Example 4

[0055] See details Figure 7 In this embodiment, the first rotating seat 40 is not located at the junction of the main support frame 20 and the side support frame 21, but is instead located on the side support frame 21. The first rotating seat 40 is connected to the flipping arm 30 via the support base 32, so that there is a gap between the first rotating seat 40 and the flipping arm 30 in a direction perpendicular to the flipping arm 30, ensuring that the first flipping seat will not interfere with the flipping arm 30 during the first-stage flipping process.

[0056] In this embodiment, the tilting arm 30 is provided with a support arm 31 to abut against the side support frame 21, so that a limiting structure is formed between the first-stage tilting seat and the second-stage tilting seat. Since the principle of the support arm 31 and the side support frame 21 forming the limiting structure is the same as in Embodiment 1, the distance relationship between the support arm 31, the first rotating seat 40 and the side support frame 21 is not described again in this embodiment.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
