Description

Technical Field

[0001] This application relates to the field of heavy machinery assembly and tilting technology, and in particular to a heavy-duty tilting mechanism. Background Technology

[0002] Current factory production demands increasingly sophisticated industrial production lines capable of precisely controlling tilting angles and handling high loads. Traditionally, the tilting of heavy workpieces relies primarily on overhead cranes, supplemented by manual labor. Overhead crane operations typically require prefabrication and installation of crane tracks, followed by multiple personnel coordinating command, rigging, and lifting. Furthermore, overhead cranes usually employ wire ropes, lifting devices, or mechanical grippers when lifting workpieces.

[0003] Regarding the aforementioned technologies, overhead crane hoisting requires the prefabrication and installation of the traveling rails and the collaboration of multiple people during hoisting. At the same time, it is unable to quickly and under high loads to flip and lift heavy workpieces, posing significant safety hazards and low efficiency. The inventor believes that overhead crane hoisting has inefficiencies and safety defects in flipping heavy workpieces. Utility Model Content

[0004] In order to achieve efficient flipping of heavy workpieces, this application provides a heavy-duty flipping mechanism.

[0005] The heavy-duty tilting mechanism provided in this application adopts the following technical solution: A heavy-duty tilting mechanism, including Upgrade organization; The mounting base is provided on the lifting mechanism; A rotating bracket is mounted on the mounting base, and the rotating bracket is provided with a placement platform and a locking mechanism. The drive mechanism includes a drive assembly and a rotary guide mechanism; The rotating bracket is connected to the mounting base by mounting shafts and bearing seats at both ends. The rotating guide mechanism includes a guide plate on the rotating bracket and a support assembly fixed on the mounting base. The guide plate and the support assembly are slidably connected.

[0006] By adopting the above technical solution, the workpiece can be placed on the placement platform, and the worker can lock the workpiece using the locking mechanism via the control panel. Then, the drive component on the drive mechanism is activated, which drives the rotating bracket to rotate via the drive bearing seat. A rotating guide mechanism is installed on the rotating bracket and the mounting base. When the workpiece is rotated, the rotating guide mechanism slides within the support component via a guide plate to assist the rotating bracket in rotating, improving the rotation efficiency of the rotating bracket and reducing wear on the mounting shafts at both ends of the rotating bracket, thus extending the service life of the rotation mechanism.

[0007] Optionally, the support assembly includes a fixed base disposed on the mounting base, a plurality of movable pulleys arranged in an arc above the fixed base, and the lower end of the guide plate is arranged in an arc and its end face abuts against the upper part of the movable pulley to achieve a sliding connection.

[0008] By adopting the above technical solution, the movable pulley installed on the top of the fixed base is slidably connected to the guide plate. When the rotating bracket needs to be flipped, the guide plate can reduce the friction caused by sliding through the movable pulley, thereby improving the smoothness of the guide plate sliding and enabling the guide rotation mechanism to better assist the rotating bracket in rotating.

[0009] Optionally, the drive assembly includes a drive motor with a speed reducer mounted on it, and the output shaft of the drive motor is coaxially fixed with the mounting shaft.

[0010] By adopting the above technical solution, the drive component involved in this application uses a drive motor and a reducer for driving, and the output shaft of the drive motor is coaxially fixed with the mounting shaft at one end of the rotating bracket. When it is necessary to flip the workpiece, the drive motor is started to drive the reducer, and the reducer can realize the rotation of the mounting shaft. The mounting shaft will drive the rotating bracket to flip. This solution realizes the automatic flipping of the rotating bracket.

[0011] Optionally, the placement platform includes a first placement frame fixed on the rotating bracket and having a placement slot, and a compensation placement frame rotatably connected to the rotating bracket and having a height higher than the placement slot; the compensation placement frame is provided with an indexing pin for fixing the compensation placement frame.

[0012] By adopting the above technical solution, the placement platform is fixed on the rotating bracket, allowing the workpiece to rotate within the placement platform as the rotating bracket rotates. The first placement frame initially fixes the workpiece on the rotating bracket, while the compensation placement frame, which is higher than the placement slot, compensates for and fixes workpieces of different shapes and sizes. This allows various workpieces of different shapes and sizes to be rotated on the rotating bracket, improving the applicability and stability of the flipping mechanism.

[0013] Optionally, the locking mechanism includes: Mounting base; fixed to the rotating bracket; A locking device, fixed on the mounting base, includes a mounting box, a locking drive assembly, a ball screw, a nut connected to the ball screw, and a linkage mechanism; The locking drive assembly includes a locking drive motor with a locking reducer; The linkage mechanism includes a first link fixed to the nut, a second link rotatably connected at one end to the first link, and a clamping block disposed at the other end of the second link; The mounting box is provided with a positioning plate, and the positioning plate is provided with an L-shaped positioning groove for guiding the clamping block to rotate toward the rotating bracket. The first connecting rod and the second connecting rod are provided with positioning rods that slide within the positioning groove.

[0014] By adopting the above technical solution, the locking mechanism is fixed to the rotating bracket via a mounting base and is integrally set with the rotating bracket. The locking device is fixed to the mounting base and drives the ball screw to rotate through the locking drive assembly. The nut on the ball screw will move up and down due to the rotation of the ball screw. The linkage mechanism, because it is connected to the nut, will move up and down along with the nut. At the same time, when the linkage mechanism moves downward, the clamping block on it will contact the workpiece, thereby achieving the locking effect. This solution is equipped with a mounting box on the locking mechanism, and a positioning plate with a positioning groove is installed in the mounting box. The linkage mechanism slides in the positioning groove through its own positioning rod, which constrains the sliding of the linkage mechanism within the fixed positioning groove and enhances the stability of the linkage mechanism during sliding. Therefore, the locking mechanism, through the combination of the locking drive assembly, linkage mechanism, mounting box and clamping block, realizes the automation of the locking mechanism and enhances its own connectivity and stability.

[0015] Optionally, the mounting box is provided with two limit switches and a directional groove, and the first connecting rod is provided with a directional rod that is slidably disposed on the directional groove and connected to the limit switch.

[0016] By adopting the above technical solution, a limit switch is installed inside the mounting box, and a directional groove is provided on the mounting box, which allows the directional rod connected to the limit switch to slide within the directional groove. Therefore, this solution improves the automation level of the locking mechanism, improves the accuracy of the limit switch movement, and thus indirectly improves the flipping accuracy of the flipping mechanism.

[0017] Optionally, the clamping block includes a touch switch and a nylon clamping block.

[0018] By adopting the above technical solution, the touch switch on the clamping block can enable the clamping block to quickly and accurately provide feedback on the pressure on the workpiece, avoiding damage to the workpiece due to untimely feedback of pressure information. Because the nylon clamping block is made of flexible nylon, it can protectively press against the workpiece surface upon contact, preventing damage to the workpiece surface from the locking mechanism.

[0019] Optionally, the lifting mechanism includes a hydraulic lift connected to the mounting base at its top and guide assemblies located on both sides of the hydraulic lift.

[0020] By adopting the above technical solution, the lifting power source of the lifting mechanism is a hydraulic lift. The hydraulic lift is connected and fixed to the mounting base to raise the height of the mounting base, thereby achieving the overall height of the lifting and tilting mechanism. A set of guide components is installed on both sides of the hydraulic lift, which helps to distribute the force on the hydraulic lift when lifting heavy workpieces, while making the hydraulic lift lift the workpiece more stably and avoiding damage to the hydraulic lift from the workpiece.

[0021] Optionally, the guide assembly includes a positioning platform connected to the mounting base and a lifting rod fixed to the outside of the hydraulic lift; a gear rack is provided on the positioning platform, and gears meshing on the gear rack are provided at both ends of the lifting rod.

[0022] By adopting the above technical solution, both positioning platforms of the guide assembly are connected and fixed to the mounting base. The gear racks on the two positioning platforms mesh with the gears of the lifting rod, which enables the guide assembly to help the hydraulic lift distribute the force and avoid the risk of the hydraulic lift being crushed by heavy workpieces. At the same time, the connection of the lifting rod ensures that the guide assembly is evenly guided by the force, thus improving the overall stability of the mechanism.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a placement platform, a locking mechanism, and a rotary guide mechanism, this application can improve the flipping accuracy of the flipping mechanism and enable the flipping mechanism to efficiently and quickly flip larger and heavier workpieces, thereby improving the efficiency of the flipping mechanism.

[0024] 2. The nylon pressure block in the locking mechanism, in conjunction with the pressure-sensing limit switch, can ensure that the contact pressure on the workpiece surface is evenly distributed, thus preventing damage to the workpiece due to pressure.

[0025] 3. The integrated operation panel reduces manual operation steps and lowers the safety risks associated with flipping workpieces. Attached Figure Description

The positioning platform 13 also serves as a support for the tilting mechanism. A gear rack 15 is installed on the positioning platform 13. The lifting rod 12 is connected to the gear rack 15. When the hydraulic lift 9 is raised, the lifting rod 12 moves on the gear rack 15 to assist the hydraulic lift 9 in raising the mounting base 2 in a balanced and stable manner.

[0038] Reference Figure 1 , Figure 3 As shown, the mounting base 2 is preferably bolted to the top of the hydraulic lift 9 in the middle, and its two sides are bolted to the top of the positioning platform 13, thereby achieving stable lifting of the mounting base 2 by the lifting mechanism 1. The rotating bracket 5 is mounted on the mounting base 2, and its two sides are fixed and rotatably connected by bearing seats 17 with mounting shafts 16. A drive mechanism 18 for driving the rotating bracket 5 is also provided on the mounting base 2.

[0039] Reference Figures 3 to 5 As shown, the drive mechanism 18 includes a drive assembly 3 and a rotary guide mechanism 6. The drive assembly 3 includes a drive motor 19 with a reducer, which is fixed to a mounting shaft 16 on either side of the rotating bracket 5, enabling the drive motor 19 to rotate the entire rotating bracket 5 on the mounting base 2. The rotary guide mechanism 6 includes a guide plate 20 and a support assembly 21. The support assembly 21 includes a fixed base 22 and a movable pulley 23.

The upper end of the guide plate 20 is fixed on the rotating bracket 5, and the lower end of the guide plate 20 has an arc-shaped end face that abuts against the movable pulley 23. It can slide on the fixed base 22 through the movable pulley 23. Two sets of rotating guide mechanisms 6 are provided, preferably distributed on both sides of the hydraulic lift 9. The rotating bracket 5 can be stably rotated by the four-point positioning of the rotating guide mechanism 6 and the bearing seat 17.

[0040] Reference Figure 4 , Figure 6As shown, two sets of placement platforms 7 are provided on the rotating bracket 5. The placement platforms 7 are preferably located next to the rotating guide mechanism 6. The placement platform 7 includes a first placement frame 25 and a compensating placement frame 26. The lower end of the first placement frame 25 is preferably welded to the rotating bracket 5, and the upper end is provided with a placement groove 27 with a horizontal surface for placing workpieces. The height of the placement surface of the compensating placement frame 26 is higher than the end face of the placement groove 27 of the first placement frame 25. The lower end of the compensating placement frame 26 is provided with a rotating shaft 28, which is rotatably connected to the fixed seat 29 of the rotating bracket 5. A dividing pin 30 is installed in the middle of the frame of the compensating placement frame 26. The dividing pin 30 passes through and is fixed to the compensating placement frame 26 and the fixed seat 29. The compensating placement frame 26 can be adjusted to compensate and fix different workpieces by adjusting the dividing pin 30. When the compensating placement frame 26 is not needed, it can be rotated 90° and laid flat below the placement groove 27.

[0041] Reference Figure 4 , Figure 7 and Figure 8 As shown, two sets of locking mechanisms 8 are also provided on the rotating bracket 5, and the locking mechanisms 8 are preferably located next to the placement platform 7. The locking mechanism 8 includes a mounting base 31 and a locking device 32; the mounting base 31 is fixed on the rotating bracket 5. The locking device 32 includes a mounting box 33, a locking drive assembly 34, a ball screw 35, a nut 36, and a connecting rod structure 37. The locking device 32 is fixed on the mounting base 31. The lower end of the locking drive assembly 34 is a locking drive motor 38 with a locking reducer, and the middle part of the locking drive assembly 34 is a ball screw 35 connected to the locking drive motor 38. When the locking drive motor 38 rotates, it will drive the ball screw 35 to rotate together. The nut 36 is installed on the ball screw 35, so when the ball screw 35 rotates, the nut 36 will move up and down on the ball screw 35. The connecting rod mechanism and the nut 36 are preferably welded together, and the connecting rod structure 37 will move up and down together with the nut 36. Mounting box 33 is installed on the outside of ball screw 35 as a protective housing. A positioning plate 39 is installed on one side of mounting box 33, and an L-shaped positioning groove 40 is provided on the positioning plate 39. A guide plate 41 is installed on the other side of mounting box 33, and a vertical guide groove 42 is provided on the guide plate 41. A limit switch 43 is installed at the bottom of the guide plate 41.

[0042] Reference Figure 7 , Figure 8As shown, the linkage structure 37 includes a first linkage 44, a second linkage 45, and a clamping block 46. The first linkage 44 is preferably welded and fixed to the nut 36, and moves up and down together with the nut 36 on the ball screw 35. One end of the first linkage 44 is provided with a guide rod 47, which is installed in a guide groove 42. A limit switch 43 is installed on the guide rod 47. When the first linkage 44 moves up and down with the nut 36, the guide rod 47 slides up and down within the guide groove 42, thus enabling the limit switch 43 to move up and down. One end of the second linkage 45 is provided with a clamping block 46. A nylon clamping block 48 is installed on the side of the clamping block 46 facing the rotating bracket 5, and a trigger switch 49 is installed on the other side. When the nylon clamping block 48 clamps the workpiece, it triggers the trigger switch 49, which preferably transmits a clamping signal to the control panel 4 via an electrical connection. The second connecting rod 45 is connected to the other end of the first connecting rod 44 via a connecting shaft 50, allowing the second connecting rod 45 to both rotate and be fixedly connected to the first connecting rod 44. Positioning rods are installed on the sides of both the first connecting rod 44 and the second connecting rod 45 at the positioning plate 39 of the mounting box 33. These positioning rods are placed within the positioning groove 40, allowing them to slide in a specific direction within the groove. When the positioning rod of the second connecting rod 45 is in the vertical section of the L-shaped guide groove, the clamping block 46 on the second connecting rod 45 faces the rotating bracket 5 and moves downwards along with the first connecting rod 44, thus clamping the workpiece. When the second connecting rod 45 is in the horizontal section of the L-shaped guide groove, the clamping block 46 is separated from the workpiece.

[0043] The implementation principle of a heavy-duty flipping mechanism in this application embodiment is as follows: When using the flipping mechanism, the operator first adjusts the height of the flipping mechanism by stepping on the pedal 11 according to their own height and the size of the workpiece, and then places the workpiece in the placement slot 27 of the first placement frame 25. According to the shape and size of the workpiece, the workpiece is compensated and fixed by the compensation placement frame 26. Then, the locking mechanism 8 is flipped by the operation control panel 4 to press the workpiece. When the locking mechanism 8 presses the workpiece, it will trigger the touch switch 49 sensor. At the same time, the sensor will transmit the pressing signal to the control panel 4. The operator can start the drive mechanism 18 according to the pressing signal fed back by the operation panel. The drive mechanism 18 will drive the bearing on the rotating bracket 5 to rotate, thereby driving the rotating bracket 5 to flip. The rotating guide mechanism 6 will assist the rotation when the rotating bracket 5 flips and keep the center of gravity of the workpiece near the axis before and after flipping. After the workpiece is assembled, the operator can operate the rotating bracket 5 to return it to the center again by the operation panel, and then release the locking mechanism 8.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
