Description
Technical Field
[0001] The present invention relates to the technical field of slings, and in particular to an electric rotating telescopic electromagnetic sling. Background Art
[0002] Electromagnetic lifter is a lifting tool that relies on strong magnetic attraction to lift heavy objects. When in use, the electromagnetic surface is in close contact with the object to be lifted to achieve stable adsorption of the object. Due to its significant advantages such as light weight, strong suction and low energy consumption, it is widely used in port cargo transportation and lifting.
[0003] Among the existing electromagnetic slings, the lifting chains are widely used due to their flexibility and strong pulling force. However, since the goods are generally heavy, they have great inertia. In order to avoid violent shaking of the goods during movement, they must be moved at a slow speed. In addition, in order to ensure the stability of the stacked goods during transportation during loading and unloading, the goods need to be stacked neatly. Users usually need to reduce the shaking of the goods before stacking them. In addition, the existing sling structure cannot make subtle adjustments to the position and rotation angle of the goods, and users still need long-term training to quickly and accurately stack the goods neatly. Summary of the invention
[0004] The object of the present invention is to provide an electric rotating telescopic electromagnetic hanger to solve the problems raised in the above background technology.

[0006] Preferably, two thread grooves are arranged on the side surface of the rotating column and are distributed in a mirror-symmetrical manner, and the two thread grooves are respectively connected to the two movable columns.
[0007] Preferably, a turntable is fixedly connected to the upper end of the bracket, a load-bearing plate is clamped in the middle of the side of the turntable, a second bevel gear is fixedly sleeved on one end of the side of the turntable, and a second motor meshing with the second bevel gear is fixedly installed above the load-bearing plate.
[0008] Preferably, four equidistant and circumferentially arranged hanging platforms are fixedly mounted on the top of the load-bearing plate, one end of each of the four hanging platforms is fixedly connected to one end of a hanging chain, and the other ends of each of the four hanging chains are fixedly sleeved with a hanging ring.
[0009] Preferably, a detection cylinder is fixedly connected to the middle of the bottom surface of the turntable, and the two ends of the detection cylinder are respectively fixedly connected to the two ends of spring one and spring two, and the other ends of spring one and spring two are fixedly connected to moving rings, and a small ball is fixedly sleeved in the moving ring.
[0010] Preferably, the spring 1 and the spring 2 are both in a compressed state, the small ball has a very high density, and the resultant force on the small ball in the vertical direction is zero when the device is stationary.
[0011] Preferably, the middle parts of the spring one and the spring two are respectively provided with motor starter one and motor starter two fixedly connected to the two ends of the detection tube, and the middle parts of the motor starter one and the motor starter two are movably sleeved with a connecting shaft fixedly sleeved with the small ball.
[0012] Preferably, a base is fixedly installed on the top of the load-bearing plate, a rectangular pillar is fixedly installed on the top of the base, a third motor fixedly sleeved with the base is provided in the middle of the rectangular pillar, a second screw is fixedly connected to the output end of the third motor, and the second screw is movably sleeved with a rectangular slider clamped in the rectangular pillar through a threaded sleeve.
[0013] Preferably, the sides of the rectangular pillars are provided with sliding grooves, and moving blocks fixedly connected to the rectangular sliders are clamped in the four sliding grooves. Limiting plates are provided on the tops of the four sliding grooves, and rotating plates are movably sleeved on both ends of the four moving blocks.
[0014] Preferably, when the connecting shaft moves to the bottom of the motor starter 1, the third motor starts to rotate in reverse, and when the connecting shaft moves to the top of the motor starter 2, the third motor starts to rotate in forward direction.
[0015] The working principle and beneficial effects of the present invention are: 1. The present invention realizes that in the process of the sling moving downward to prepare for stacking the goods, the ball will move upward relative to the sling under the action of inertia, so that the connecting shaft fixedly sleeved with the ball moves to the top of the motor starter 2, so that the third motor rotates forward, and the rectangular slider moves upward in the rectangular pillar with the forward rotation of the third motor, and the moving block moves upward along the slide slot. Since the length of the limit plate is greater than the moving block, and the rotating plate fixedly connected with the moving block under the joint action of the lifting chain will rotate with the limit plate as the fulcrum while moving upward with the moving block, thereby supporting the lifting chain before the goods are neatly stacked, enhancing the stability of the sling, significantly reducing the shaking of the sling, and facilitating the stacking operation for users. In addition, when the sling moves upward after the stacking is completed, the ball moves downward relative to the sling under the action of inertia and moves the connecting shaft to the bottom of the motor starter 1, so that the third motor is reversed, and the rotating plate is away from the limit plate, thereby restoring the flexibility of the lifting chain. Such a cycle can realize the rapid lifting of the goods while ensuring the accuracy of the goods when they are neatly stacked.
[0016] 2. The present invention arranges adjustment devices, turntables and other devices. When stacking goods, the second motor can be started to rotate the turntable through the second bevel gear transmission, and then the bracket can be slowly rotated, so that the rotation angle of the goods to be loaded and unloaded reaches a preset angle. At this time, the first motor can be started to rotate the first screw, and the support column can be moved inside the support plate through thread transmission, thereby driving the electric permanent magnetic suction plate and the goods fixedly connected to one end of the support plate to move, and the position and rotation angle of the goods can be finely adjusted to achieve neat stacking of the goods.

Before loading and unloading the goods, the first motor 8 can be started according to the length of the goods, and the rotating column 6 can be rotated through the first bevel gear 7. Under the action of the thread groove 14, the two moving columns 3 will move away from each other along the notch 5, so that the two moving shafts 2 and the two electric permanent magnetic suction plates move away from each other, so that the distance between the two electric permanent magnetic suction plates 13 is consistent with the length of the goods to be loaded and unloaded.
[0022] Among them, the upper end of the bracket 1 is fixedly connected to a turntable 15, a bearing plate 16 is clamped in the middle of the side of the turntable 15, one end of the side of the turntable 15 is fixedly sleeved with a second bevel gear 17, a second motor 18 meshing with the second bevel gear 17 is fixedly installed above the bearing plate 16, and four equidistant circumferentially arranged hanging platforms 19 are fixedly installed on the top of the bearing plate 16, one end of the four hanging platforms 19 is fixedly connected to one end of a hanging chain 20, and the other end of the four hanging chains 20 is fixedly sleeved with a hanging ring 21, which can be connected Connect the lifting device. When the goods need to be stacked neatly, the second motor 18 can be started to rotate the turntable 15 through the second bevel gear 17, and then the bracket 1 can be slowly rotated, so that the rotation angle of the goods to be loaded and unloaded reaches a preset angle. At this time, the first motor 8 can be started to rotate the first screw 10, and the support column 12 can be moved inside the support plate 9 through thread transmission, thereby driving the electric permanent magnetic suction plate 13 at one end and the goods to move, and the position and angle of the goods can be slowly adjusted to achieve neat stacking of the goods.
[0023] Among them, a detection cylinder 22 is fixedly connected to the middle part of the bottom surface of the turntable 15, and the two ends of the detection cylinder 22 are respectively fixedly connected to the two ends of the spring 1 23 and the spring 2 24, and the other ends of the spring 1 23 and the spring 2 24 are fixedly connected to a moving ring 25, and a small ball 26 is fixedly sleeved in the moving ring 25. The spring 1 23 and the spring 2 24 are both in a compressed state. The small ball 26 has a very high density. The resultant force in the vertical direction on the small ball 26 is zero when the device is stationary. Since the resultant force in the vertical direction on the small ball 26 is zero when the hanger is stationary, the small ball is in a stationary state. However, when the hanger moves up and down, since the density of the small ball 26 is very high, it has a large inertia. Therefore, when the hanger moves downward, the spring 1 23 rebounds, and the small ball 26 moves upward relatively to further squeeze the spring 2 24. When the hanger moves upward, the spring 2 24 rebounds, and the small ball 26 moves downward relatively to squeeze the spring 1 23.
[0024] Among them, the middle parts of the spring 1 23 and the spring 24 are respectively provided with a motor starter 1 27 and a motor starter 28 fixedly connected to the two ends of the detection tube 22, and the middle parts of the motor starter 1 27 and the motor starter 28 are movably sleeved with a connecting shaft 29 fixedly sleeved with the ball 26. When the connecting shaft 29 moves to the bottom of the motor starter 1 27, the third motor 30 starts to reverse, and when the connecting shaft 29 moves to the top of the motor starter 28, the third motor 30 starts to rotate forward. When the sling is used to load and unload goods, the usual process The sling is moved to above the goods to be loaded and unloaded, and then the sling is moved downward to absorb the goods, and then the sling is raised to move the goods to above the preset position, and finally the sling is moved downward to stack the goods neatly, wherein when the sling moves upward, the small ball 26 moves downward relatively due to the action of inertia and moves the connecting shaft 29 to the bottom of the motor starter 27 to make the third motor 30 reverse, and when the sling moves downward, the small ball 26 moves upward relatively due to the action of inertia and moves the connecting shaft 29 to the top of the motor starter 28 to make the third motor 30 rotate forward.
[0025] Among them, a base 31 is fixedly installed on the top of the load-bearing plate 16, a rectangular pillar 32 is fixedly installed on the top of the base 31, a third motor 30 fixedly sleeved with the base is provided in the middle of the rectangular pillar 32, the output end of the third motor 30 is fixedly connected with a second screw 33, the second screw 33 is movably sleeved with a rectangular slider 34 clamped in the rectangular pillar 32 through a threaded sleeve, when the third motor 30 rotates forward, since the rectangular slider 34 is movably sleeved with the second screw 33 through a threaded sleeve and clamped in the rectangular pillar 32, the rectangular slider 34 will move upward in the rectangular pillar 32 with the forward rotation of the third motor 30, and when the third motor 30 reverses, the rectangular slider 34 will move downward under the action of the second screw 33 and the rectangular pillar 32.
[0026] Among them, the sides of the rectangular pillars 32 are all provided with sliding grooves 35, and the four sliding grooves 35 are all clamped with moving blocks 36 fixedly connected to the rectangular slider 34. Limiting plates 37 are set on the tops of the four sliding grooves 35, and rotating plates 38 are movably sleeved at both ends of the four moving blocks 36. The upward movement of the rectangular slider 34 will cause the moving blocks 36 to move upward along the sliding grooves 35, and then cause the rotating plate 38 to move upward and rotate with the limiting plate 37 as the fulcrum under the action of the lifting chain 20, so as to support the lifting chain 20 when the lifting device moves downward, enhance the stability of the lifting device, and significantly reduce the shaking of the lifting device. When the rectangular slider 34 moves downward, the rotating plate 38 is away from the limiting plate 37 to enable the lifting device to work normally.
[0027] Working principle: Before loading and unloading the goods, the first motor 8 can be started according to the length of the goods, and the rotating column 6 can be rotated through the first bevel gear 7. Under the action of the thread groove 14, the two movable columns 3 will move away from each other along the notch 5, so that the two movable shafts 2 and the two permanent magnetic suction plates move away from each other, so that the distance between the two permanent magnetic suction plates 13 matches the length of the goods to be loaded and unloaded. When using a sling to load and unload goods, the usual process is to move the sling to the top of the goods to be loaded and unloaded, and then move the sling downward to adsorb the goods, and then raise the sling to move the goods to the top of the preset position, and finally move the sling downward to start the second motor 18 to rotate the turntable 15 through the second bevel gear 17, and then the bracket 1 is slowly rotated, so that the rotation angle of the goods to be loaded and unloaded reaches the preset angle, at this time, the first motor 8 can be started to rotate the first screw 10, and the support column 12 is moved inside the support plate 9 through thread transmission, thereby driving the permanent magnetic suction plate 13 at one end and the goods to move, and the position and angle of the goods are slowly adjusted to achieve neat stacking of the goods.
[0028] In the process of the sling moving downward to prepare for stacking the goods, the ball 26 will move upward relative to the sling under the action of inertia, so that the connecting shaft 29 fixedly sleeved with the ball 26 moves to the top of the motor starter 28 to make the third motor 30 rotate forward, and the rectangular slider 34 will move upward in the rectangular support 32 with the forward rotation of the third motor 30, and make the moving block 36 move upward along the slide groove 35. Since the length of the limit plate 37 is greater than that of the moving block 36, the rotating plate 38 fixedly connected to the moving block 36 will move upward with the moving block 36 under the action of the lifting chain 20. The positioning plate 37 is used as a fulcrum for rotation, so as to support the lifting chain 20 before the goods are neatly stacked, enhance the stability of the sling, significantly reduce the shaking of the sling, and facilitate the stacking operation for users. In addition, when the sling moves up after stacking, the ball 26 moves downward relative to the sling under the action of inertia and moves the connecting shaft 29 to the bottom of the motor starter 27 to reverse the third motor 30 and move the rotating plate 38 away from the limiting plate 37, thereby restoring the flexibility of the lifting chain 20. Such a cycle can achieve rapid lifting of the goods while ensuring their accuracy when they are neatly stacked.
[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
