Detailed implementation manners

[0041] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention fall within the scope of protection of the present invention.

[0042] The following combines Figures 1 to 5 to describe the flipping device and flipping system for flipping a trailer beam assembly of the present invention.

[0043] As Figure 1 and Figure 2 shown, a flipping device for flipping a trailer beam assembly provided by the present invention includes at least one flipping unit for flipping the trailer beam assembly by 180 degrees.

[0044] Among them, the flipping unit includes a cantilever 2, a flipping mechanism and a flipping drive device.

[0045] Specifically, the flipping mechanism includes a flipping frame for fixing the trailer beam assembly. The flipping drive device includes a first telescopic drive device 14, a second telescopic drive device 15, and a drive rotating rod. The drive rotating rod is rotatably connected to the cantilever 2, and both ends of the drive rotating rod are rotatably connected to the flipping frame. The telescopic ends of the first telescopic drive device 14 and the second telescopic drive device 15 are respectively rotatably connected to both ends of the drive rotating rod, and the first telescopic drive device 14 and the second telescopic drive device 15 are rotatably connected to one end of the cantilever 2 away from the drive rotating rod, that is, the first telescopic drive device 14 and the second telescopic drive device 15 are rotatably connected to one end of the cantilever 2 away from the flipping frame. In this way, the flipping frame is driven to flip by controlling the rotation of the drive rotating rod through two telescopic drive devices.

[0046] When the first telescopic drive device 14 extends and the second telescopic drive device 15 contracts, the drive rotating rod rotates, causing the drive rotating rod to drive the flipping frame to rotate, thereby realizing the flipping of the flipping frame.

[0047] It should be noted that when the first telescopic drive device 14 is in a fully contracted state and the second telescopic drive device 15 is in a fully extended state, the flipping frame is in a horizontal state; when the first telescopic drive device 14 and the second telescopic drive device 15 are both in an intermediate state (that is, both the first telescopic drive device 14 and the second telescopic drive device 15 are in a semi-extended or semi-contracted state), the flipping frame is in a vertical state, that is, the flipping frame flips 90 degrees; when the first telescopic drive device 14 is in a fully extended state and the second telescopic drive device 15 is in a fully contracted state, the flipping frame flips 180 degrees.

[0048] Here, the first telescopic drive device 14 and the second telescopic drive device 15 can be hydraulic cylinders, pneumatic cylinders, or electric push rods.

[0049] With such a setting, the trailer beam assembly is fixed on the flipping frame, and the flipping frame is driven to rotate by controlling the rotation of the drive rotating rod through two telescopic drive devices, realizing the flipping of the trailer beam assembly, so that the trailer beam assembly can be stably flipped 180 degrees horizontally, and the trailer beam assembly will not be squeezed during the flipping process, and the trailer beam assembly will not be deformed and damaged.

[0050] In an alternative embodiment of the present invention, the flipping drive device further includes a first connecting rod 16 and a second connecting rod 17. Both ends of the first connecting rod 16 are respectively rotatably connected to the flipping frame and the first end of the drive rotating rod, and both ends of the second connecting rod 17 are respectively rotatably connected to the flipping frame and the second end of the drive rotating rod. In this way, it is convenient for the drive rotating rod to drive the flipping frame to flip.

[0051] In an alternative embodiment, the driving rotating rod may include a first rotating rod 18 and a second rotating rod 19. The first end of the first rotating rod 18 is rotatably connected to the cantilever 2, and the second end of the first rotating rod 18 is rotatably connected to the telescopic end of the first telescopic driving device 14 and the first connecting rod 16. The first end of the second rotating rod 19 is rotatably connected to the cantilever 2, and the second end of the second rotating rod 19 is rotatably connected to the telescopic end of the second telescopic driving device 15 and the second connecting rod 17. In this way, it is convenient to realize the flipping of the flipping frame.

[0052] In an alternative embodiment of the present invention, the flipping unit further includes a column 3 and a lifting driving device. Wherein, the cantilever 2 is slidably arranged on the column 3, and the lifting end of the lifting driving device is connected to the cantilever 2, so that the lifting driving device can drive the cantilever 2 to lift along the column 3, thereby driving the flipping frame to lift by the cantilever 2. In this way, the lifting driving device can drive the flipping frame away from the ground, thereby reserving a space for the flipping of the trailer beam assembly to avoid abrasion or failure to achieve a horizontal 180-degree flip when the trailer beam assembly is flipping and contacting the ground.

[0053] It should be noted that the distance that the lifting driving device drives the cantilever 2 to rise is greater than or equal to half of the width of the trailer beam assembly.

[0054] In an alternative embodiment, the lifting driving device may be a lifting telescopic cylinder or an electric push rod, and the push rod of the lifting telescopic cylinder or the electric push rod is fixedly connected to the cantilever 2. Here, the lifting telescopic cylinder or the electric push rod is fixedly installed on the column 3, and the moving direction of the push rod is parallel to the column 3. The lifting telescopic cylinder may be a lifting hydraulic cylinder or a lifting air cylinder.

[0055] In another alternative embodiment, the lifting driving device includes a chain 8, a driving sprocket 9, a driven sprocket, and a lifting motor for driving the driving sprocket 9 to rotate. Wherein, the chain 8 is threaded through the column 3, and both ends of the chain 8 are connected to the cantilever 2. The driving sprocket 9 and the driven sprocket are respectively rotatably arranged at the upper and lower ends of the column 3, and the chain 8 meshes with the driving sprocket 9 and the driven sprocket. In this way, the lifting motor drives the driving sprocket 9 to rotate to drive the chain 8 to move, thereby driving the cantilever 2 to lift.

[0056] Here, the lifting motor rotating forward can drive the cantilever 2 to move upward, and the lifting motor rotating in reverse can drive the cantilever 2 to move downward.

[0057] In other embodiments, the lifting driving device may be a ball screw mechanism. The ball screw mechanism includes a ball screw and a motor for driving the lifting screw of the ball screw to rotate. The motor may be arranged at the top of the column 3. The lifting screw of the ball screw is rotatably arranged on the column 3 and is parallel to the column 3. The cantilever 2 is connected to the lifting nut of the ball screw. The lifting of the cantilever 2 is realized by controlling the rotation of the lifting screw of the ball screw by the motor.

[0058] In an alternative embodiment of the present invention, the flipping frame includes a flipping base 10 and a clamping assembly. The middle part of the flipping base 10 is rotatably connected to the cantilever 2, and both ends of the driving rotating rod are rotatably connected to the flipping base 10. Specifically, the first connecting rod 16 and the second connecting rod 17 are rotatably connected to the flipping base 10. The clamping assembly is used to clamp the longitudinal beam wing plate of the trailer beam assembly, and the clamping assembly is arranged on the flipping base 10. In this way, driving the flipping base 10 to flip can drive the trailer beam assembly to flip.

[0059] In this embodiment, the middle part of the flipping base 10 is rotatably connected to one end of the cantilever 2 far from the column 3 through a connecting plate. In this way, it can not only improve the stability and strength of the flipping base 10, but also facilitate the realization of flipping.

[0060] In an alternative embodiment, the clamping assembly includes two clamping claws 11 and a clamping driving device. The clamping driving device is used to drive the two clamping claws 11 to approach or separate from each other, so that the two clamping claws 11 can grip or release the longitudinal beam wing plate of the trailer beam assembly.

[0061] Here, the two clamping claws 11 are slidably arranged on the flipping base 10.

[0062] And the clamping driving device may include a lead screw mechanism and a driving motor 12.

[0063] Among them, the lead screw mechanism includes a lead screw and two nuts. The lead screw is rotatably arranged on the flipping base 10. The two nuts are threadedly connected to the lead screw, and the lead screw is a double-thread screw, that is, two threads with opposite helix directions are arranged on the lead screw, and the two nuts respectively match the two threads. The two clamping claws 11 are respectively connected to the two nuts. In this way, rotating the lead screw can drive the two nuts to approach or separate from each other, so as to drive the two clamping claws 11 to approach or separate from each other.

[0064] The driving motor 12 is used to drive the lead screw to rotate. Here, the driving motor 12 can be arranged on the cantilever 2.

[0065] In this embodiment, driving the driving motor 12 to rotate forward can drive the two nuts to approach each other, so that the two clamping claws 11 approach each other to clamp the longitudinal beam wing plate of the trailer beam assembly; driving the driving motor 12 to rotate in reverse can drive the two nuts to separate from each other, so that the two clamping claws 11 separate from each other to release the longitudinal beam wing plate of the trailer beam assembly.

[0066] In an alternative embodiment, two groups of detection elements are arranged on the flipping base 10. The two groups of detection elements are used to detect the clamping state of the two clamping claws 11 on the trailer beam assembly, that is, the two groups of detection elements are used to detect whether the two clamping claws 11 clamp the longitudinal beam wing plate of the trailer beam assembly.

[0067] Among them, the two groups of detection elements can be arranged near the middle position of the flipping seat 10, and there is a gap between the two groups of detection elements. The gap between the two groups of detection elements can be equal to or less than the thickness of the longitudinal beam flange of the trailer beam assembly.

[0068] Here, the detection elements can detect the positions of the clamping claws 11. When the two groups of detection elements respectively detect the two clamping claws 11, it means that the two clamping claws 11 clamp the longitudinal beam flange of the trailer beam assembly.

[0069] Specifically, the detection elements can be photoelectric induction switches 13. When both of the two photoelectric induction switches 13 detect the two clamping claws 11, it indicates that the two clamping claws 11 clamp the longitudinal beam flange of the trailer beam assembly. When only one group of photoelectric induction switches 13 or both groups of photoelectric induction switches 13 detect the clamping claws 11, it means that the two clamping claws 11 do not clamp the longitudinal beam flange of the trailer beam assembly.

[0070] It should be noted that the above detection elements can also be infrared sensors, or travel switches, or other detection devices.

[0071] In an alternative embodiment of the present invention, the flipping device for flipping the trailer beam assembly includes two flipping units. The two flipping units are arranged side by side, and the flipping frames of the two flipping units can fix the same trailer beam assembly, that is, the clamping claws 11 of the two flipping units can clamp the longitudinal beam flange of the same trailer beam assembly. In this way, it is beneficial to improve the stability of the fixation of the trailer beam assembly, and can prevent the trailer beam assembly from falling during the flipping process due to excessive gravity, thereby improving the flipping efficiency.

[0072] In an alternative embodiment of the present invention, the flipping device for flipping the trailer beam assembly further includes a hydraulic station system 6 and an electric control system 7. The hydraulic station system 6 is used to provide power for the first telescopic driving device 14 and the second telescopic driving device 15, and the electric control system 7 can regulate the hydraulic station system 6, thereby realizing automatic control.

[0073] In this embodiment, the electric control system 7 can be communicatively connected to the lifting driving device, the clamping driving device, and the detection elements, so as to facilitate the realization of automatic control.

[0074] Moreover, the flipping device for flipping the trailer beam assembly can also include a remote controller. The remote controller is communicatively connected to the electric control system 7, so as to facilitate the operator to regulate and control each device through the remote controller.

[0075] Next, a flipping system for flipping a trailer beam assembly provided by the present invention will be described. The flipping system for flipping a trailer beam assembly described below can be mutually corresponding and referred to the flipping device for flipping a trailer beam assembly described above.

[0076] Such as Figure 1As shown, a flipping system for flipping a trailer beam assembly provided by the present invention includes a flipping device and a lifting trolley for lifting the trailer beam assembly. Here, the flipping device can be the flipping device for flipping the trailer beam assembly described in any of the above embodiments, and the lifting trolley can drive the trailer beam assembly to move to the flipping device, so that the flipping unit of the flipping device flips the trailer beam assembly.

[0077] In an alternative embodiment of the present invention, the flipping system for flipping the trailer beam assembly further includes a track 1. The flipping unit of the flipping device is located above the track 1, and the lifting trolley can move along the track 1 to facilitate moving the trailer beam assembly to the flipping device, so that the clamping claws 11 of the flipping unit can clamp the longitudinal beam wing plate of the trailer beam assembly.

[0078] Here, the flipping system can include two parallel tracks 1 and two sets of lifting trolleys located on the two tracks 1. The two sets of lifting trolleys can respectively lift the two ends of the trailer beam assembly. In this way, the balance of the trailer beam assembly during transportation can be ensured, and it is convenient for the clamping claws 11 of the flipping unit to clamp the longitudinal beam wing plate of the trailer beam assembly.

[0079] In some embodiments, the flipping unit further includes a swing oil cylinder 5. The swing oil cylinder 5 is slidably connected to a column 3 through a lifting slide plate 4. A cantilever 2 is rotatably connected to the lifting slide plate 4, and the swing oil cylinder 5 is rotatably connected to the lifting slide plate 4. The telescopic end of the swing oil cylinder 5 is rotatably connected to the cantilever 2. By the telescoping of the swing oil cylinder 5, the cantilever 2 can be driven to rotate horizontally, so as to avoid the flipping unit from hindering the movement of the lifting trolley.

[0080] It should be noted that the lifting slide plate 4 can be connected to the lifting end of a lifting drive device.

[0081] When it is necessary to flip the trailer beam assembly by 180 degrees, first, the two sets of lifting trolleys support the trailer beam assembly and drive it to stop at a suitable position on the track 1 parallel to the two flipping units; then, the swing oil cylinders 5 of the two flipping units push the cantilevers 2 to rotate horizontally by 90 degrees, so that the cantilevers 2 of the two flipping units are located on the track 1 and perpendicular to the trailer beam assembly;

[0082] Then, the lifting drive device drives the lifting slide plate 4 to slowly rise, so that the upper end surface of the flipping frame fits the bottom of the trailer beam assembly, and the drive motor 12 drives the two clamping claws 11 to approach each other until the clamping claws 11 clamp the longitudinal beam wing plate of the trailer beam assembly;

[0083] Then, the lifting slide plates 4 of the two flipping units continue to slowly rise synchronously. After rising to a certain height, the first telescopic drive devices 14 of the two flipping units extend synchronously, and the first telescopic drive devices 14 of the two flipping units contract synchronously, jointly pushing the flipping frame to drive the trailer beam assembly to complete a smooth flip of 0°→90°→180°;

[0084] After the flipping is completed, the lifting slides 4 of the two flipping units slowly descend synchronously. When they reach the position where they fit onto the tops of the two groups of lifting trolleys under the trailer beam assembly, they stop. The drive motor 12 drives the two clamping claws 11 to move away from each other, releasing the longitudinal beam flanges of the trailer beam assembly. Then, the lifting slides 4 of the two flipping units rise synchronously by a certain height, and the swing cylinder 5 retracts, causing the cantilever 2 to rotate to a position parallel to the track 1.

[0085] Finally, the two groups of lifting trolleys carry the trailer beam assembly out.

[0086] The device embodiments described above are merely illustrative. Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. Those of ordinary skill in the art can understand and implement it without creative efforts.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
