Description

Technical Field

[0001] This invention relates to the field of lifting devices, specifically a lifting device that is easy to rotate. Background Technology

[0002] In industrial production and construction, lifting equipment is widely used for suspending and transporting various objects. Traditional lifting equipment typically uses chains, ropes, or wire ropes as suspension devices, relying on the lifting motion of the crane to suspend and transport objects. When lifting bulk objects, such as sand, gravel, and concrete, hoppers are used. After being lifted onto the construction platform, the objects need to be rotated and tilted. Most current lifting equipment uses hydraulic cylinders or rotary motors to drive the equipment to rotate and tilt. However, traditional lifting equipment may suffer from instability during tilting operations, vibration during the tilting process, and difficulty in controlling the tilting speed, thus reducing the efficiency and safety of lifting operations. Summary of the Invention

[0003] To address the existing problems, this invention provides a lifting device that is easy to flip, which can effectively solve the problems mentioned in the background art.

[0005] A lifting device that is easy to flip includes a frame, a hopper between the frames, the bottom of the hopper being movably connected to the frame via a shaft, and a power mechanism including two winches positioned on either side of the hopper's rotation direction. A traction rope is wound around each winch and connected to the upper side of the hopper. The two winches are drive-connected, with one winch connected to a power motor. The traction ropes on the two winches are wound in opposite directions. A lifting ring is fixedly connected to the top of the frame.

[0006] As a further embodiment of the present invention: the hoisting mechanism includes two end seats and a rotating rod, the rotating rod is movably connected between the two end seats, and four baffles are fixedly connected to the rotating rod, with each pair of baffles forming a group, and the two baffles forming a winding cavity for the traction rope. Two hooks are fixedly connected to each side of the hopper, and the traction rope is fixedly connected to the hooks.

[0007] As a further embodiment of the present invention: gears are fixedly connected to the rotating rods of both winch mechanisms, and the two gears are connected by a gear chain meshing. The power motor is driven by one of the rotating rods.

[0008] As a further embodiment of the present invention: a base plate is fixedly connected to the bottom surface of the upright frame, the hoisting mechanism is fixed on the base plate, and support legs are provided at the four corners of the bottom surface of the base plate.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Combination Figures 1 to 3 This embodiment provides a lifting device that is easy to rotate, including a frame 1, which is a portal frame structure. A hopper 2 is provided between the frames 1. The bottom surface of the hopper 2 is movably connected to the frame 1 through a shaft 3. The power mechanism includes two winch mechanisms 4 arranged on both sides of the rotation direction of the hopper 2. A traction rope 5 is wound on the winch mechanism 4 and connected to the upper side of the hopper 2. The two winch mechanisms 4 are connected in a transmission manner, and one of the winch mechanisms 4 is connected to a power motor 6. The traction ropes 5 on the two winch mechanisms 4 are wound in opposite directions. A lifting ring 7 is fixedly connected to the top of the frame 1.

[0022] like Figure 1-2As shown, the hoisting mechanism 4 includes two end seats 41 and a rotating rod 42. The rotating rod 42 is movably connected between the two end seats 41. Four baffles 43 are fixedly connected to the rotating rod 42, with each pair of baffles 43 forming a group. The two baffles 43 enclose a winding cavity for the traction rope 5. Two hooks 8 are fixedly connected to each side of the hopper 2. The traction rope 5 is fixedly connected to the hooks 8. The two baffles 43 limit the movement of the traction rope 5. When the rotating rod 42 rotates, it can rewind or unwind the traction rope 5, thereby using the traction rope 5 to pull and tilt the hopper 2. Meanwhile, during the lifting process, the traction rope 5 can pull the hopper 2 to maintain its stability. At the same time, gears 9 are fixedly connected to the rotating rods 42 of the two winch mechanisms 4. The two gears 9 are connected by a toothed chain 10. The power motor 6 is connected to one of the rotating rods 42. The power motor 6 drives the two shafts 3 to rotate in the same direction at the same time. When the two traction ropes 5 are wound in opposite directions, one traction rope 5 is wound up and the other traction rope 5 is unwound, thus ensuring the stability of the hopper 2 when it is flipped.

[0023] like Figure 1-2 As shown, a base plate 11 is fixedly connected to the bottom surface of the upright frame 1. The hoisting mechanism 4 is fixed to the base plate 11. Support legs 12 are provided at the four corners of the bottom surface of the base plate 11. The upright frame 1 is located in the middle of the base plate 11. At the same time, a level sensor 13 and a balancing device 14 are provided on the top surface of the base plate 11. The level sensor 13 is a gyroscope or other instrument that can measure the level of the base plate 11, such as a spirit level. The balancing device 14 adjusts the level of the base plate 11 according to the data measured by the level sensor 13, so as to ensure that the base plate 11 is always in a horizontal state during the hoisting process, thereby ensuring that the hopper 2 is in a square position.

[0024] like Figure 3 As shown, the balancing device 14 includes a housing 141 fixed in the middle of the base plate 11. A rotating rod 142 is movably connected to the middle of the housing 141. A servo motor 143 is driven to the outer end of the rotating rod 142. A bearing 144 is fixedly connected to the inner end of the rotating rod 142. A crossbar 145 is rotatably connected to the bearing 144, allowing the crossbar 145 to rotate vertically around the bearing 144. A smooth rod 146 is slidably connected to the other end of the crossbar 145. A rolling frame 147 is fixedly connected to the bottom of the smooth rod 146. A counterweight ball 148 is movably connected to the rolling frame 147. The servo motor 143 drives the rotating rod 142 to rotate, thereby causing the crossbar 145 to rotate around the housing 141. The counterweight ball 148 on the crossbar 145 applies pressure to the base plate 11, and the horizontal balance of the base plate 11 is adjusted according to the position of the counterweight ball 148.

[0025] like Figure 1 As shown, a vibrating motor 15 is installed on the outside of the hopper 2. When the material is being discharged, the vibrating motor 15 can discharge the material quickly and ensure that the material is discharged completely, thus preventing the material from sticking to the inner wall of the hopper 2.

[0026] like Figure 1-2 As shown, protrusions 16 are fixedly connected to the four corners of the top surface of the hopper 2. The two sides of the upright frame 1 are provided with protrusions 17 corresponding to the protrusions 16. An elastic rope 18 is fixedly connected between the protrusions 17 and the protrusions 16. The elastic rope 18 is made of a highly elastic rope. During the flipping process, the elastic rope 18 can further enhance the stability of the flipping. At the same time, a proximity switch 19 is installed on the side of the upright frame 1 located in the middle of the hopper 2 and close to the hopper 2. The flipping position of the hopper 2 is controlled by the proximity switch 19.

[0027] The working principle of this invention is as follows: the hoisting mechanism 4 drives the hopper 2 to rotate around the shaft 3, and the traction rope 5 on the hoisting mechanism 4 winds in opposite directions. When the hopper 2 rotates, one side of the traction rope 5 unwinds and the other side of the traction rope 5 winds up, thereby ensuring the stability of the hopper 2 when it is overturned. At the same time, it is easy to control the overturning speed, improves the efficiency and safety of the lifting action, and the overall structure is simple and easy to operate.
