DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not used to limit the scope of the present application.

[0041] In the description of the present application, it should be noted that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] See also Figures 1 to 8 As shown, the embodiment of the present application provides a wing damage repair training platform, including a chassis 1 and an angle flip mechanism 2. The chassis 1 is provided with a walking mechanism 3, and the angle flip mechanism 2 includes a driving assembly 21 and a support bracket 22. The driving assembly 21 is provided on the chassis, and the support bracket 22 is connected to the driving assembly 21 by transmission. The driving assembly 21 can drive the support bracket 22 to rotate to adjust the angle formed between the support bracket 22 and the chassis 1. The wing damage repair training platform of the present application is provided with a driving assembly 21 that can drive the support bracket 22 to rotate. The wing 6 to be repaired is placed on the support bracket 22. The driving assembly 21 can drive the support bracket 22 to rotate, and the support bracket 22 drives the wing 6 to flip, so that the wing 6 stays at the angle that is most convenient for maintenance, which solves the disadvantage that the traditional wing repair training platform cannot achieve angle adjustment. According to the requirements of the repair operation, the wing 6 can be flipped and stopped at various angles from horizontal to vertical, which greatly facilitates the repair process and thus improves the efficiency of wing 6 damage repair.

[0044] In some possible implementations, such as Figure 5As shown, the driving assembly 21 includes a support column 211 and a telescopic component 212, wherein the support column 211 is connected to the chassis 1, one end of the telescopic component 212 is hinged to the chassis 1, and the support bracket 22 is hinged to the other end of the support column 211 and the telescopic component 212, respectively. The telescopic movement of the telescopic component 212 can drive the support bracket 22 to rotate, so as to adjust the angle formed between the support bracket 22 and the chassis 1. After the wing 6 is placed on the support bracket 22, the plane where the wing 6 is located is substantially parallel to the plane where the main part of the support bracket 22 is located, so the angle value of the rotation of the support bracket 22 is roughly equal to the angle value of the rotation of the rotating wing 6. The telescopic component 212, the support bracket 22 and the support column 211 form a triangle with three hinged corners. As the telescopic component 212 is extended, the support bracket 22 gradually flips from a state parallel to the chassis 1 to a state perpendicular to the chassis 1. As the telescopic component 212 is shortened, the support bracket 22 gradually flips from a state perpendicular to the chassis 1 to a state parallel to the chassis 1. By adjusting the length of the telescopic member 212, the wing 6 can be kept parallel to the chassis 1, perpendicular to the chassis 1, or at any angle between parallel and perpendicular. The wing 6 can be kept at an angle that is most convenient for inspecting the part to be inspected according to the inspection needs. The telescopic member 212 can be a telescopic cylinder, a telescopic oil cylinder, or other structural parts that can be extended and shortened.

[0045] In some possible implementations, such as Figures 1 to 6 As shown, the support bracket 22 includes a main support 221 and a side support 222. The main support 221 is hinged to the support column 211 and the telescopic component 212 respectively. The side support 222 is arranged at one end of the main support 221 along the length direction. A limiting clamping groove is formed between the side support 222 and the main support 221.

[0046] The side support 222 includes a limiting portion 2221 and a supporting portion 2222, one end of the supporting portion 2222 is connected to one end of the main support 221 along the length direction, one end of the limiting portion 2221 is connected to the other end of the supporting portion 2222, and the other end of the limiting portion 2221 extends to the other end of the main support 221. The space enclosed by the main support 221, the supporting portion 2222 and the limiting portion 2221 is the limiting clip groove. When the wing 6 is placed on the support bracket 22, one side of the wing 6 is located in the limiting clip groove, the supporting portion 2222 is located on one side of the width or length direction of the wing 6, and the main support 221 and the limiting portion 2221 are located on both sides of the thickness direction of the wing 6. When the wing 6 is in a state parallel to the chassis 1, the main support 221 mainly provides support for the wing 6. In the process of flipping the wing 6 from the parallel base 25 state to the vertical base 25, the main support 221 and the supporting portion 2222 provide support for the wing 6 at the same time. When the wing 6 is in a state perpendicular to the chassis 1, the support portion 2222 mainly provides support for the wing 6, and the main support 221 and the limiting portion 2221 limit the wing 6 from both sides of the wing 6 to ensure that the vertical state of the wing 6 is stable and not easy to flip over.

[0047] The limiting portion 2221 and the supporting portion 2222 may be integrally formed, and the main support 221 and the side support 222 may be connected via a connecting piece.

[0048] In some possible implementations, such as Figure 5 As shown, the main support 221, the limiting portion 2221 and the supporting portion 2222 are all provided with a supporting layer 224 on one side close to the limiting clip groove. The supporting layer 224 can be made of materials with a certain buffering effect such as rubber, silicone, and plastic, and the supporting layer 224 can be connected to the main support 221, the limiting portion 2221 and the supporting portion 2222 by bonding, clamping, or fixing with a connector.

[0049] In some possible implementation schemes, the main support 221, the limiting portion 2221 and the support portion 2222 all include a bottom plate and flanges on both sides of the bottom plate, a groove is formed between the bottom plate and the flange, one side of the support layer 224 is embedded in the groove, and the other side protrudes out of the groove. The flange of the support portion 2222 is connected to the flange of the main support 221 by fasteners, and the bottom edge of the main support 221 is hinged to the support column 211 and the telescopic component 212.

[0050] In some possible implementations, such as Figures 1 to 4 As shown, the wing damage repair training platform includes at least two angle flipping mechanisms 2, and each angle flipping mechanism 2 is arranged at intervals. The two angle flipping mechanisms 2 support the wing 6 at the same time, and the support is more stable and not easy to roll over.

[0051] Preferably, the wing damage repair training platform includes two angle flipping mechanisms 2. The two angle flipping mechanisms 2 can stably support the wing 6 as long as the distance between them is reasonable. It is not necessary to set too many angle flipping mechanisms 2. The structure is simple and the cost is reduced.

[0052] In some possible implementations, the telescopic component 212 may be a telescopic hydraulic cylinder, which has the advantages of strong power, stable operation, and high durability, and is sufficient to provide the flipping force for the flip wing 6 .

[0053] In some possible implementations, such as Figures 1 to 4 and Figure 6 As shown, the wing damage repair training platform also includes a variable amplitude transmission mechanism 4, which is arranged on the chassis 1. Each of the angle flipping mechanisms 2 can be movably arranged on the chassis 1, and the variable amplitude transmission mechanism 4 is respectively connected to each of the angle flipping mechanisms 2 in transmission to drive and adjust the spacing between each of the angle flipping mechanisms 2. The traditional fixed wing repair training platform has poor compatibility. Generally, wing repair training platforms of different specifications and sizes are required to correspond to wings 6 of different specifications. The number of platforms is large and not easy to maintain and store. In addition, the truss structure wing repair platform with a fixed angle flipping mechanism 2 has a fixed angle flipping mechanism 2. During the process of supporting the wing 6, when repairing the partial cover of the wing 6, sometimes the support cannot quickly and effectively avoid the partial cover. Generally, the wing 6 is moved to avoid the position by hoisting by a crane, which is cumbersome to operate. The wing damage repair training platform of the present application sets the angle anti-rotation mechanisms to be adjustable, which expands the universality of the wing damage repair training platform, can meet the support and flipping of wings 6 of various sizes and specifications, reduces the configuration cost of multiple models of repair platforms, and can avoid positions that require inspection and positions that are not suitable for being pressed through amplitude adjustment.

[0054] In some possible implementations, such as Figures 1 to 4 As shown, the chassis 1 is provided with a first guide rail 11, and each of the angle flip mechanisms 2 includes a slider 23, and the slider 23 is slidably connected to the first guide rail 11. Preferably, the wing damage repair training platform includes two first guide rails 11, and the angle flip mechanism 2 includes four sliders 23, and every two sliders 23 are slidably connected to one first guide rail 11. In this way, the supporting state of the angle flip mechanism 2 is stable when it is not sliding, and the angle flip mechanism 2 is stable when it slides.

[0055] Furthermore, the angle flip mechanism 2 includes a base 25 , four sliders 23 are evenly arranged at four corners below the base 25 , and the top of the base 25 is connected to the support column 211 .

[0056] The variable amplitude transmission mechanism 4 includes a rotary drive member 41 and a lead screw 42. The lead screw 42 is rotatably arranged on the chassis 1, and the lead screw is parallel to the first guide rail 11. A threaded sleeve 24 is arranged on the angle flip mechanism 2, and the threaded sleeve 24 is threadedly connected to the lead screw 42. The rotary drive member 41 is arranged on the chassis 1, and the rotary drive member 41 is transmission-connected to the lead screw 42. The rotary drive member 41 drives the lead screw to rotate to drive the angle flip mechanism 2 to move toward each other or away from each other. The threaded sleeve 24 is driven to move by the rotation of the lead screw 42, and then the angle flip mechanism 2 is driven to move. Such cooperation makes the moving process smooth and facilitates accurate positioning operation. Among them, the threaded sleeve 24 can be fixedly connected to the base 25.

[0057] Furthermore, in the actual implementation process, the lead screw 42 can be arranged in a variety of ways and cooperated with the rotating drive member 41. This embodiment shows the following two implementation methods:

[0058] The first type, the screw 42 includes a first screw segment and a second screw segment, the first screw segment and the second screw segment are an integral part, the thread rotation direction of the first screw segment is opposite to the thread rotation direction of the second screw segment, and the threaded sleeves 24 of the two angle flipping mechanisms 2 are respectively threadedly connected to the first screw segment and the second screw segment. In this embodiment, the rotary drive member 41 includes a motor 411 and a reduction box 412, the reduction box 412 has an output end, the first screw segment and the second screw segment are integrally formed, the middle part of the screw 42 is transmission-connected to the output end of the reduction box 412, and the first screw segment and the second screw segment are arranged on both sides of the rotary drive member 41. The thread rotation directions of the threaded sleeves 24 on the angle flipping mechanisms 2 arranged on both sides of the rotary drive member 41 are also opposite. Compared with the second embodiment, this embodiment only needs to install one screw 42, and there is no need to judge the rotation direction and installation direction of the screw 42 during the installation process, and the installation process is simpler.

[0059] The second type, the lead screw 42 includes a first lead screw body and a second lead screw body, the first lead screw body and the second lead screw body are two single pieces, the rotary drive member 41 includes a motor 411 and a reduction box 412, the reduction box 412 has two output ends, the first lead screw body and the second lead screw body are connected to the two output ends respectively, and the threaded sleeves 24 of the two angle flipping mechanisms 2 are respectively threadedly connected to the first lead screw body and the second lead screw body. In this embodiment, the first lead screw body and the second lead screw body are two separate sections of the lead screw 42. The thread rotation directions on the first lead screw body and the second lead screw body can be opposite, at this time, the two output ends of the reduction box 412 turn in the same direction, and the thread rotation directions of the threaded sleeves 24 on the angle flipping mechanism 2 on both sides of the rotary drive member 41 are also opposite. The threads of the first lead screw body and the second lead screw body can also have the same rotation direction, at this time, the two output ends of the reduction box 412 turn in opposite directions. The lead screw 42 section set in this embodiment is shorter than that in the first embodiment, and the material production and transportation are simpler. A suitable embodiment can be selected according to actual production, installation and use conditions.

[0060] Furthermore, the rotary drive member 41 further includes a reducer bracket 413, the reducer bracket 413 is arranged on the chassis 1, the reduction box 412 is connected to the reducer bracket 413, the reducer bracket 413 is provided with a through hole, and the lead screw 42 passes through the through hole.

[0061] In some possible implementation schemes, a first groove is provided on the chassis 1, the variable amplitude transmission mechanism 4 is provided in the groove, the lead screw 42 is located between the two first guide rails 11, the threaded sleeve 24 is located in the middle below the base 25, and the sliders 23 are provided around the threaded sleeve 24.

[0062] In some possible implementations, such as Figures 1 to 4 and Figure 8 As shown, the wing damage repair training platform also includes an auxiliary support member 5, which can provide auxiliary support force for the wing 6 at the bottom of the wing 6 when the wing 6 is parallel to the chassis 1 or the angle between the plane of the wing 6 and the plane of the chassis 1 is small, so that the wing 6 is placed more stably. Since the support and tightening components of the fixed truss structure wing repair platform are generally fixed, it is impossible to quickly and effectively avoid the repair of the wing local cover during the process of supporting the wing. Generally, it is moved by hoisting by a crane, which is cumbersome.

[0063] The chassis 1 is provided with a second guide rail 12, and the auxiliary support member 5 comprises a telescopic rod 51 and a top support seat 52 and a bottom support seat 53 connected to both ends of the telescopic rod 51, and the bottom support seat 53 is slidably connected to the second guide rail 12. The auxiliary support member 5 can translate bidirectionally along the second guide rail 12 and adjust the position to assist in supporting the wing at a suitable position.

[0064] In some possible implementation schemes, the end surface of one side of the top support seat 52 is a plane, and is covered with an anti-skid layer, which can be made of a material with a certain elasticity such as rubber, silicone, PVC, etc. A universal ball head is provided on the side of the top support seat 52 away from the anti-skid layer, and a universal ball head seat is provided on the telescopic rod 51. The top support seat 52 is connected to the universal ball head seat of the telescopic rod 51 through the universal ball head, so that the top support seat 52 can adjust the angle to ensure that the wing 6 can fit under the wing 6 at various angles, providing stable support force.

[0065] Preferably, the wing damage repair training platform includes multiple (at least two) second guide rails 12 and multiple auxiliary support members 5, and the multiple auxiliary support members 5 are respectively arranged on the corresponding second guide rails 12. Multiple auxiliary support members 5 can be arranged on each second guide rail 12. The multiple support members 5 can be respectively supported on different parts of the wing, so that the bottom of the wing 6 is evenly stressed and supported more stably.

[0066] In some possible implementations, such as Figure 8 As shown, the telescopic rod 51 is hinged to the bottom support seat 53, and the bottom support seat 53 is provided with a positioning hole, and the telescopic rod 51 is provided with a positioning matching hole 513 adapted to the positioning hole. The telescopic rod 51 has a storage state parallel to the chassis 1 and a support state perpendicular to the chassis 1. In the support state, the positioning pin passes through the positioning hole and the positioning matching hole 513 to lock the position of the telescopic rod 51, so that the telescopic rod 51 remains in a vertical state. In the storage state, the positioning hole and the positioning matching hole 513 are misaligned. Since the wing 6 rotates from a state parallel to the chassis 1 to a state perpendicular to the chassis 1, as the angle gradually increases, the auxiliary support member 5 will hinder the wing 6 from continuing to rotate, so the auxiliary support member 5 needs to avoid. If the auxiliary support member 5 is frequently disassembled, it is not only troublesome, but also easy to damage the auxiliary support member 5 and the connection structure. The auxiliary support member 5 is set to be foldable and stored, so that the auxiliary support member 5 can be switched between the use support state and the avoidance storage state more conveniently.

[0067] In some possible implementations, the telescopic rod 51 includes a main body section 511 and a telescopic section 512. A cavity is provided in the main body section 511, and a through hole communicating with the cavity is provided at the end of the main body section 511. The telescopic section 512 is partially located in the cavity, and partially extends out of the main body section 511 through the through hole. A nut is provided at the through hole, and the telescopic section 512 is provided with an external thread that matches the nut thread. The length of the telescopic section 512 exposed from the main body section 511 can be adjusted by manually rotating the telescopic section 512.

[0068] In some possible implementations, the bottom support seat 53 includes a limit plate 54, and the telescopic rod 51 abuts against the limit plate 54 when it is in a vertical state perpendicular to the chassis 1. When the telescopic rod 51 becomes a vertical state, the limit plate 54 limits the telescopic rod 51, so that the telescopic rod 51 can be positioned in a vertical state at the fastest speed, making the operation more convenient.

[0069] Furthermore, a second sinking groove is provided on the chassis 1, and the second guide rail 12 is provided in the second sinking groove, and when the auxiliary support member 5 is in the storage state, the height of the highest point of the auxiliary support member 5 is lower than the height of the lowest point when the support bracket 22 is in the state of being vertical to the chassis 1. It is further ensured that the auxiliary support member 5 will not affect the flipping of the wing 6.

[0070] In some possible implementations, such as Figures 1 to 4 and Figure 7 As shown, the walking mechanism 3 includes multiple walking components 31, and each walking component 31 is arranged on the chassis 1. Each walking component 31 includes a motor and a Mecanum wheel, the motor is connected to the chassis, and the Mecanum wheel is connected to the corresponding motor. The Mecanum wheel can achieve all-round movement, including forward, backward, left and right translation, oblique and on-site U-turn. The Mecanum wheel is used to move and adjust the posture of the wing damage repair training platform, and improve the accuracy and safety of the movement of the wing damage repair training platform.

[0071] Preferably, the wing damage repair training platform includes four groups of walking components 31 , which are arranged at four corners of the chassis 1 .
