[0023] Example 1
[0024] like Figures 1-5 As shown in the figure, the assisted tilting and lifting device proposed in this embodiment includes a hoisting mechanism, a support mechanism, and a swing arm adjustment assembly.
[0025] The hoisting mechanism includes a vertically arranged connecting column 13, a rotating frame 10 located at the bottom of the connecting column 13, two sets of mounting components symmetrically arranged at the bottom of the rotating frame 10, and a first clamping mechanism and a second clamping mechanism respectively mounted on the two sets of mounting components. The two clamping mechanisms can clamp onto both sides of the material. Handles 12 are provided at both ends of the bottom of the rotating frame 10, providing convenient gripping for workers to lift, flip, and lower the material. A pneumatic manual valve 30 is installed on one of the handles 12. Workers control the direction of the power assist by operating the pneumatic manual valve 30, thus assisting in lifting and lowering the material.
[0026] The swing arm adjustment assembly is rotatably mounted on the support mechanism. The swing arm adjustment assembly includes a swing arm assembly with one end rotatably connected to the top of the connecting column 13, a counterweight assembly located at the other end of the swing arm assembly, and a cylinder assembly rotatably connected to both the support mechanism and the swing arm assembly on the side where the counterweight assembly is located. The counterweight assembly and cylinder assembly are located on the opposite side of the lifting mechanism, serving as a counterweight and providing auxiliary support.
[0027] The pneumatic manual valve 30 is connected to the cylinder assembly for control. Workers can control the cylinder assembly by moving the lever of the pneumatic manual valve 30. Moving the lever upwards assists in raising the lifting mechanism, the two clamping mechanisms, and the material clamped between them. Moving the lever downwards assists in lowering the lifting mechanism, the two clamping mechanisms, and the material clamped between them. The worker's movement direction is the same as the direction of force applied by the cylinder assembly, facilitating material handling and flipping.
[0028] The mounting assembly includes a mounting sleeve 11 at the bottom of the rotating frame 10, a second connecting block 8 rotatably connected to the end of the mounting sleeve 11, a first connecting block 7 connected to the second connecting block 8, and a rotating frame 9 mounted on the first connecting block 7. A rotating shaft is rotatably mounted on the rotating frame 10. Both the first and second clamping mechanisms include a first synchronous pulley at the end of the rotating shaft, a second synchronous pulley connected to the second connecting block 8, and a synchronous belt meshing with the first and second synchronous pulleys. The second connecting block 8 has a rotating rod portion rotatably mounted on the mounting sleeve 11, and the second synchronous pulley is coaxially mounted on the rotating rod portion. When one set of clamping mechanisms rotates, it can drive the other set of clamping mechanisms to rotate synchronously via the synchronous belt drive, thereby smoothly flipping the material and preventing the material from swaying during movement.
[0029] like Figure 2As shown, the first clamping mechanism includes a first clamping frame 101 mounted on a rotating frame 9 in a set of mounting components, two sets of first positioning frames 201 at both ends of the first clamping frame 101, a connecting frame 301 in the middle of the first clamping frame 101, two sets of first clamping blocks 31 symmetrically rotatably mounted on the connecting frame 301, and a first handle 41 connected to the first clamping blocks 31. Rotating the first handle 41 can drive the first clamping blocks 31 to rotate, so as to clamp the material on one side using the first clamping blocks 31. A first pad is detachably connected between the two sets of first clamping blocks 31.
[0030] like Figure 3 As shown, the second clamping mechanism includes a second clamping frame 102 mounted on a rotating frame 9 in another set of mounting components, two sets of second positioning frames 202 located at both ends of the second clamping frame 102, two sets of second clamping blocks 32 symmetrically rotatably mounted on the second clamping frame 102, and a second handle 42 connected to the second clamping blocks 32. Rotating the second handle 42 can drive the second clamping blocks 32 to rotate, thereby clamping the material on the other side using the second clamping blocks 32. A second pad is detachably connected between the two sets of second clamping blocks 32. Two cylinders 6 are symmetrically arranged on both the first clamping frame 101 and the second clamping frame 102, and the output end of the cylinder 6 is connected to a chuck 5.
[0031] The material is first placed in the area between the two clamping mechanisms and pre-positioned by the positioning frame. Then, the handle is rotated, causing the clamping blocks to rotate and abut against the material. Next, the cylinder 6 pushes the chuck 5 to move, clamping the material. This multiple positioning and clamping method ensures the material is securely held and will not fall when lifted. The clamping mechanism can rotate 360°. A detachable pad is connected between the two sets of clamping blocks. The thickness of the pad limits the distance between the two sets of clamping blocks. By changing the pads of different thicknesses, the distance between the two sets of clamping blocks can be adjusted, making it suitable for clamping materials of different sizes.
[0032] This embodiment can clamp materials over a wider range and assist workers in flipping and transferring materials, making it more flexible to use. When the material is within the working range of this device, the worker adjusts the position of the clamping mechanism by gripping the handle 12, aligning the two clamping mechanisms with both sides of the material to be processed, then clamps the material from both sides, lifts the material upwards, and then flips the material. During the lifting process, the counterweight assembly and cylinder assembly assist the worker in lifting, reducing labor intensity. When assisting, the worker controls the direction of assistance by manually moving the lever on the pneumatic switch manual valve 30, making operation convenient.
[0033] Example 2
[0034] like Figures 1-5As shown, the assisted tilting and lifting device proposed in this embodiment, compared with the first embodiment, the support mechanism in this embodiment includes a support base 29, a connecting base 28 and a rotating base 27 connected in sequence from bottom to top, and a control box 26 set on the rotating base 27. An air storage tank 25 is set on the rotating base 27.
[0035] The swing arm assembly includes a swing arm 14 rotatably connected at one end to the top of the connecting column 13, a mounting base 15 rotatably connected to the other end of the swing arm 14, two parallel connecting arms 17 rotatably connected at both ends to the rotating base 27 and the mounting base 15 respectively, and a counterweight arm 19 disposed on the connecting arm 17. The swing arm 14 can be rotated within a range of 270° relative to the mounting base 15. The mounting base 15, the connecting arm 17, and the rotating base 27 form a parallelogram mechanism. The connecting arm 17 can be pitched, raising the material clamped by the clamping assembly when tilted up and lowering the clamped material when tilted down.
[0036] The cylinder assembly includes a booster cylinder 22, a lifting cylinder 23, and an auxiliary cylinder 24. The air supply volume and timing to the cylinders 22, lifting cylinder 23, and auxiliary cylinder 24 are controlled by the air tank 25 via the control box 26. The operation of the booster cylinder 22 is controlled by the pneumatic switch manual valve 30. The bottom ends of the booster cylinder 22, lifting cylinder 23, and auxiliary cylinder 24 are rotatably connected to the rotating seat 27, and the top ends are rotatably connected to the counterweight arm 19. When lifting materials held by the two clamping mechanisms, the booster cylinder 22, lifting cylinder 23, and auxiliary cylinder 24 retract, causing the counterweight arm 19 to move downwards, assisting in lifting the materials with the aid of the counterweight assembly. When lowering the clamped materials, the booster cylinder 22, lifting cylinder 23, and auxiliary cylinder 24 extend, pushing the counterweight arm 19 upwards, assisting in lowering the materials. The booster cylinder 22 can increase the weight of materials that can be lifted and lowered based on the auxiliary cylinder 24 and the lifting cylinder 23, thereby enhancing the performance of the entire device.
[0037] A folding boom crane 16 is connected between the swing arm 14 and the mounting base 15. The folding boom crane 16 increases the lifting capacity of this device, enabling it to lift heavier materials. Figure 4As shown, the folding boom crane 16 includes a first pull rod 161 rotatably connected at one end to the swing arm 14, a rotating sleeve 164 rotatably mounted on the mounting base 15, a second pull rod 163 rotatably connected at one end to the rotating sleeve 164, and a bidirectional screw 162 whose two ends are respectively threaded to the other ends of the first pull rod 161 and the second pull rod 163 to adjust the distance between the first pull rod 161 and the second pull rod 163. By rotating the bidirectional screw 162, the first pull rod 161 and the second pull rod 163 can be tightened to ensure the pulling force of the folding boom crane 16 on the swing arm 14. The bidirectional screw 162 is threadedly connected to the first pull rod 161 and the second pull rod 163, which has self-locking properties and can keep the overall length of the folding boom crane 16 stable after adjustment.
[0038] The counterweight assembly includes a mounting shaft 20 located at the outer end of the counterweight arm 19 and several counterweight rings 21 mounted on the mounting shaft 20. The counterweight rings 21 and the mounting base 15 are distributed on both sides of the rotating base 27. The counterweight rings 21 can serve as a counterweight to assist personnel in lifting materials. A reinforcing arm 18 is provided on the connecting arm 17 to further improve the structural strength and deformation resistance of the connecting arm 17.
[0039] This embodiment can rotate within a 360° circumferential range, and can transfer materials to the target position within the circumferential range, with a large material handling range.
[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
