Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of early warning spreaders, and in particular to an intelligent spreader capable of automatic early warning. Background Art
[0002] A sling is a device used in lifting machinery to lift heavy objects. The most commonly used slings for lifting piece items are hooks and slings, but other slings include lifting rings, suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry. The hook is often suspended from a wire rope using components such as a pulley block. The top of the wire rope is connected to a capstan. By rotating the capstan and reeling in the wire rope, the hook and the load are lifted.
[0003] To prevent the risk of unhooking during lifting, existing hooks are often equipped with a safety latch that rotates on one side of the hook. A torsion spring provides thrust, forcing one end of the safety latch into contact with the end of the hook. When hooking the weight, the safety latch is pushed to compress the torsion spring, opening the latch. The spring then rebounds, pushing the safety latch and hook together, providing a safety mechanism. However, after prolonged outdoor use, the torsion spring is exposed to the sun and rain and is prone to rust, leading to problems such as stuck rebound, slow rebound, and loose closure.

[0043] like Figures 1 to 12 As shown:
[0044] An intelligent lifting device with automatic warning function includes a frame 1 and a pair of horizontal moving components 2. The horizontal moving components 2 are mounted on the frame 1 and are used to drive the frame 1 to move horizontally along the crossbeam. After the heavy object is lifted by the lifting component 3, the frame 1 is moved horizontally by the horizontal moving component 2 to achieve the transfer of the heavy object. The lifting device also includes a lifting component 3, a driving component 4 and a closing warning component 5. The lifting component 3 includes a housing 30, a support shaft 31, a turntable 32, a hook 33 and a steel cable 34. The support shaft 31 passes through the turntable 32 and is coaxially connected to the turntable 32. The support shaft 31 passes through the side wall of the housing 30 and is rotatably connected to the turntable 32. The top of the hook 33 is rotatably connected to the outer periphery of the support shaft 31. The steel cable 34 passes through the housing 30 and is wrapped around the outer periphery of the turntable 32. The driving component 4 is mounted on the frame 1 and is used to drive the lifting component 3 to work, hooking the hook 33 to the lifting ring on the heavy object. Then, the driving component 4 drives the steel cable 34 to move, thereby driving the housing 30 to move up and down to lift the heavy object. The closing warning assembly 5 includes a safety bolt 50, a rotating shaft 51, a pair of torsion springs 52, a cylindrical gear 53, a rack 54, a return spring 55, a base 56 and a vibration ringing mechanism 6. One end of the safety bolt 50 is coaxially connected to the outer periphery of the rotating shaft 51, and the other end of the safety bolt 50 is in conflict with the end of the hook 33. The rotating shaft 51 passes through the side wall of the hook 33 and is rotatably connected thereto. The torsion spring 52 is sleeved on the outer periphery of the rotating shaft 51. One end of the torsion spring 52 is fixedly connected to the safety bolt 50, and the other end of the torsion spring 52 is fixedly connected to the hook 33. The cylindrical gear 53 is coaxially connected to the periphery of the rotating shaft 51, the rack 54 is engaged with the cylindrical gear 53, the top of the rack 54 passes through the top wall of the hook 33 and the bottom wall of the shell 30 and is slidably connected thereto, the bottom of the base 56 is fixedly connected to the top of the rack 54, the return spring 55 is sleeved on the periphery of the rack 54, one end of the return spring 55 is fixedly connected to the bottom of the base 56, and the other end of the return spring 55 is fixedly connected to the bottom wall of the shell 30, and the vibration ringing mechanism 6 is installed on the base 56, and the vibration ringing mechanism 6 is used to generate vibration and ringing sound. When the lifting ring on the heavy object is hung with the hook 33, it first pushes the safety pin 50 to rotate, causing the torsion spring 52 to compress and rotate, and the safety pin 50 is opened. Then the torsion spring 52 rebounds and drives the safety pin 50 to reset to ensure that it will not slip during the lifting process. When the torsion spring 52 rusts and fails, causing the piston pin to get stuck, the cylindrical gear 53 rotates a certain angle along the rotating shaft 51. Through the meshing transmission between the cylindrical gear 53 and the rack 54, the rack 54 is pushed upward to lift the base 56 and the vibration bell mechanism 6, so that the vibration bell mechanism 6 is in the working state. Then, when the housing 30 driven by the movement of the steel cable 34 moves upward, the turntable 32 rotates and drives the vibration bell mechanism 6 to work and generate vibration and alarm sound. The alarm sound has an early warning effect, and the vibration can also loosen the stuck safety pin 50, further improving safety. At this time, the return spring 55 is in a compressed state. The thrust provided by the return spring 55 can not only reset the base 56, but also provide thrust to close the safety pin 50.
[0045] like Figures 1 to 8 As shown:
[0046] The vibration ringing mechanism 6 includes a bell 60, a striker 61, a gear rod 62, a telescopic rod 63, a thrust spring 64, a disc 65 and a plurality of gear blocks 66. One end of the bell 60 is fixedly connected to the inner wall of the outer shell 30, one end of the striker 61 is in conflict with the bell 60, the other end of the striker 61 is fixedly connected to the gear rod 62, one end of the telescopic rod 63 is fixedly connected to the inner wall of the base 56, the telescopic end of the telescopic rod 63 is fixedly connected to the other end of the gear rod 62, the thrust spring 64 is sleeved on the outer periphery of the telescopic rod 63, one end of the thrust spring 64 is fixedly connected to the base 56, the other end of the thrust spring 64 is fixedly connected to the gear rod 62, the disc 65 is coaxially connected to the outer periphery of the support shaft 31, the gear block 66 can be vertically rotatably installed on the disc 65, and the gear block 66 is in conflict with the gear rod 62. When the base 56 is lifted up, as the housing 30 rises, the support shaft 31 rotates driven by the turntable 32, and the disc 65 drives the tooth block 66 to rotate, and one of the tooth blocks 66 pushes the gear rod 62 to move toward the end away from the bell 60, compressing the thrust spring 64. During this process, the telescopic rod 63 plays a role in keeping the gear rod 62 moving smoothly in the horizontal direction. As the disc 65 continues to rotate, the tooth block 66 separates from the gear rod 62, and the thrust spring 64 rebounds to push the gear rod 62 and the striker 61 to move horizontally, and causes the striker 61 to hit the bell 60 to issue a warning sound. The continuous rotation of the disc 65 will continuously sound the alarm, thereby reminding the staff that the safety pin 50 is stuck when lifting heavy objects, and the vibration generated by the impact will be transmitted to the cylindrical gear 53 and the rotating shaft 51 through the rack 54, which can loosen the safety pin 50 to a certain extent, thereby improving safety.
[0047] like Figures 1 to 8 As shown:
[0048] The vibration alarm mechanism 6 also includes multiple tension springs 67, one end of which is fixedly connected to a tooth block 66. A plurality of grooves 650 are defined on the periphery of the disk 65. The plurality of tooth blocks 66 are circumferentially arranged around the disk 65 and rotatably connected to the inner wall of the grooves 650. The other ends of the tension springs 67 are fixedly connected to the inner wall of the grooves 650. During the ascent of the hook 33, the support shaft 31 rotates counterclockwise, causing one side of the tooth block 66 to contact the inner wall of the groove 650, thereby pushing the gear rod 62 to move. As the disk 65 rotates, the plurality of tooth blocks 66 continuously push the gear rod 62, causing the striker 61 to repeatedly strike the bell 60. During the descent of the hook 33, the support shaft 31 rotates clockwise, causing the gear rod 62 to push the tooth block 66, which stretches the tension springs 67. As the disk 65 rotates, the tooth blocks 66 separate from the gear rod 62, thereby preventing the alarm from accidentally ringing during the lowering of the hook 33.
[0049] like Figures 1 to 10 As shown:
[0050] The lifting assembly 3 also includes a pair of capstans 35, a pair of rotating seats 36, and a pair of spur gears 37. The top of the rotating seat 36 is fixedly connected to the bottom of the frame 1. The capstans 35 are rotatably connected to the rotating seat 36. The ends of the steel cable 34 are respectively fixedly connected to opposite sides of the two capstans 35. The spur gears 37 are coaxially connected to the capstans 35. The spur gears 37 are rotated to drive the capstans 35 to rotate, so that the steel cable 34 can be reeled around the periphery of the capstans 35. When one capstan 35 is stationary and the other capstan 35 is rotating, one end of the steel cable 34 is stationary and the other end is reeled in or reeled in, thereby driving the housing 30 to move upward for lifting or downward for lowering, thereby achieving the operation of lifting heavy objects.
[0051] like Figures 1 to 11 As shown:
[0052] The drive assembly 4 includes a bracket 40, a first gear 41, and a first motor 42. The bracket 40 is mounted on the frame 1 so as to be vertically movable. The first motor 42 is fixedly connected to one end of the bracket 40. The output shaft of the first motor 42 is coaxially connected to the first gear 41, and the first gear 41 meshes with the spur gear 37. When the first motor 42 is energized, its output shaft drives the first gear 41 to rotate. Through the meshing transmission between the first gear 41 and the spur gear 37, the two capstans 35 are simultaneously driven to rotate in the same direction, causing one capstan 35 to reel in the line and the other to pay out the line. At this time, the steel cable 34 drives the turntable 32 and the support shaft 31 to rotate, and the height of the housing 30 remains unchanged, so that idling can be performed to detect whether the safety buckle is closed before lifting, further improving safety.
[0053] like Figures 1 to 11 As shown:
[0054] The drive assembly 4 also includes a pair of second gears 43, a rotating plate 44, and a pair of shafts 45. The two shafts 45 are rotatably connected to the ends of the rotating plate 44, one of which passes through the bottom of the bracket 40 and is rotatably connected thereto. The second gear 43 is coaxially connected to the outer periphery of the shaft 45. The two second gears 43 are meshed with each other, and the two second gears 43 are respectively meshed with the two spur gears 37. When one of the second gears 43 is meshed with the spur gear 37, one of the second gears 43 is rotated. Through the meshing transmission between the second gear 43 and the spur gear 37, one of the capstans 35 can be driven to rotate for reeling in and out. When the two second gears 43 are meshed with the spur gear 37 at the same time, both capstans 35 can be driven to rotate simultaneously. The meshing transmission between the two second gears 43 causes the two capstans 35 to rotate in opposite directions, allowing the two capstans 35 to reel in and out the line simultaneously, thereby increasing the rate at which the hook 33 is lifted and lowered.
[0055] like Figures 1 to 11 As shown:
[0056] Drive assembly 4 also includes a pair of hydraulic rods 46, symmetrically located on either side of bracket 40. The bottoms of hydraulic rods 46 are fixedly connected to the top of frame 1, and the telescopic tops of hydraulic rods 46 extend through and are fixedly connected to bracket 40. When hydraulic rods 46 are activated, their telescopic ends drive bracket 40 up and down. When bracket 40 is in the top position, second gear 43 engages spur gear 37, allowing lifting. When bracket 40 is in the bottom position, first gear 41 engages spur gear 37, allowing the safety latch 50 to be checked for engagement without lifting.
[0057] like Figures 1 to 11 As shown:
[0058] The drive assembly 4 also includes a pair of knobs 47 and a cylinder 48. The two knobs 47 are rotatably connected to one side of the bracket 40 and the rotating plate 44, respectively. One end of the cylinder 48 is fixedly connected to the periphery of one of the knobs 47, and the telescopic end of the cylinder 48 is fixedly connected to the periphery of the other knob 47. When the bracket 40 is in the top position, the cylinder 48 is activated, and its telescopic end drives the rotating plate 44 to rotate about the shaft 45. At the same time, the knob 47 rotates to adjust the angle between the two second gears 43, thereby selecting the lifting speed according to the working conditions. This can reduce the impact of inertia on the lifting equipment while ensuring working efficiency, further improving safety.
[0059] like Figures 1 to 11 As shown:
[0060] The drive assembly 4 further includes a pair of pulleys 49, which are driven by a belt. One pulley 49 is coaxially connected to the periphery of the motor's output shaft, and the other pulley 49 is coaxially connected to the periphery of one of the shafts 45. Due to the belt transmission between the two pulleys 49, when the first motor 42 drives the first gear 41 to rotate, one of the shafts 45 rotates synchronously with the motor's output shaft, thereby simultaneously driving the second gear 43 to rotate, thereby driving the lifting assembly 3.
[0061] like Figures 1 to 12 As shown:
[0062] Two pairs of connecting plates 10 are fixedly connected to the top of the frame 1. The horizontal movement assembly 2 includes a pair of support plates 20, a support rod 21, two pairs of rollers 22, and a second motor 23. The two ends of the support rod 21 pass through the two connecting plates 10 and are fixedly connected to the two support plates 20. Two sets of rollers 22 are rotatably mounted on the two support plates 20. The second motor 23 is mounted on one of the support plates 20 and is used to drive one set of rollers 22 to rotate. The bottoms of the two sets of rollers 22 respectively contact the bottom walls of the grooves 650 on the overhead crane beam, so that the sling is installed on the beam, and the second motor 23 drives the rollers 22 to roll, which can drive the sling to move horizontally along the overhead crane beam, thereby completing the lifting movement.
