Description

Technical Field

[0001] The invention relates to the technical field of lifting, and in particular to a lifting device for a box-shaped large structural member with a flipping function and a use method thereof. Background Art

[0002] The box-type large structural component lifting device is mainly designed for lifting, flipping and transporting large box-type structural components, such as containers, large mechanical equipment boxes, etc. In the fields of ports, logistics, manufacturing, etc., large box-type structural components are often required to be lifted, and the box-type components need to be stacked during loading and unloading to save loading space. When stacking, the box-type structural components often need to be flipped to make the stacking compact. Therefore, the development of a box-type large structural component lifting device with a flipping function has important practical significance.

[0003] According to a lifting device and lifting method for adjusting and positioning the aerial posture of a steel box arch rib disclosed in a Chinese patent document with announcement number CN107338733B, the vertical inclination angle can be adjusted by independently controlling a single lifting point, including the lifting height of the jack and the rotation of the shaft of the lifting device mechanism; the angle of the steel box arch rib can be fine-tuned more accurately through the rotation of the shaft and the lifting ears of the steel box arch rib, thereby reducing the repeated adjustment workload caused by equipment manufacturing errors and insufficient aerial posture accuracy during installation during traditional lifting, ensuring rapid and accurate positioning of the steel box arch rib during installation, and improving construction efficiency.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when the above equipment is used, the flipping angle of the steel box is limited. Through the control of a single lifting point, the corner of the steel box can only be aligned with the ground. At this time, if the steel box is lowered vertically, it may be bumped, and the center of gravity of the steel box will shift when it is flipped, which may cause the lifting rope to shake, thereby affecting the installation accuracy of the steel box.

[0005] Therefore, there is an urgent need to improve the box-type large structural member lifting device with a flipping function to solve the above-mentioned problems. Summary of the invention

[0016] A method for using a box-shaped large structural member lifting device with a flipping function comprises the following steps: S1: First, the lifting lug is connected to the lifting hook of the lifting device. The lifting slider is located in the middle of the T-shaped support arm. The lifting device is started to transfer the T-shaped support arm to the top of the box-shaped component so that the bottom side of the chuck fits with the upper end of the box-shaped component. S2: Then start the clamping motor to drive the two driven bevel gears to rotate in the opposite direction through the active bevel gear. At this time, the two screws rotate in the opposite direction and drive the two chucks to slide in the opposite direction through the threaded slider. The two chucks clamp the box-shaped component in the opposite direction and fix it. Start the lifting device to lift the box-shaped component. S3: When the box-shaped component needs to be turned over for stacking, the driving motor is started to drive the first gear and the second gear to rotate through the driving shaft, the first gear drives the rotating seat to rotate through the chain, and the rotating seat drives the box-shaped component to rotate toward one side of the T-shaped support arm through the clamping plate module and the clamping head, and at the same time, the second gear drives the hook through the double-head hook chain to generate lateral pulling force on the box-shaped component; S4: During the rotation of the rotating seat, the center of gravity of the T-arm and the box-shaped component as a whole will shift, causing the T-arm to tilt. During the tilting of the T-arm, the metal hanging hammer will swing accordingly. The bottom end of the metal hanging hammer will contact the protective plate to form a circuit for the travel motor. The travel motor rotates through the worm gear to drive the travel gear, thereby causing the hanging slider to slide on the linear rack, automatically adjusting the position of the hanging slider and the center of gravity of the T-arm and the box-shaped component as a whole, so that the bottom end of the T-arm tends to be vertical, and then the bottom end of the box-shaped component tends to be horizontal; S5: When the box-type component is hoisted to a suitable stacking position, the clamping motor is started to drive the two clamps away from each other through the active bevel gear, the driven bevel gear and the screw rod, and the hook can be removed.

[0017] The present invention has at least the following beneficial effects: The present invention can fix the box-type component by driving the clamping head through the clamping plate module, and the driving motor can drive the rotating seat to rotate through the chain, and the rotating seat can drive the box-type component to rotate, so that the box-type component can be flipped 90 degrees left and right. During the rotation of the box-type component, the hanging slider connected to the hook can slide left and right to balance the gravity of the T-shaped support arm and the box-type component, so that the center of gravity of the T-shaped support arm and the box-type component is always directly below the hook, which can reduce the shaking amplitude of the lifting rope, thereby improving the installation accuracy and stacking efficiency of the box-type component.

[0018] The driving motor drives the first gear and the second gear to rotate through the driving shaft. The first gear rotates at the bottom end of the suspension mechanism through the chain drive rotating seat, providing a basic rotational force to the splint module. Then the second gear generates a certain displacement through the meshing transmission double-headed hook chain. The double-headed hook chain generates a pulling force on the bottom side of the box-type component through the hook. The cooperation between the double-headed hook chain and the splint module can reduce the load of the driving motor and thereby improve the flipping efficiency.

[0019] During the rotation of the rotating seat of the present invention, the center of gravity of the T-shaped arm and the box-shaped component as a whole will shift to cause the T-shaped arm to tilt slightly. During the tilting of the T-shaped arm, the metal pendant will swing accordingly. The contact between the bottom end of the metal pendant and the protective plate will form a circuit path for the travel motor. The travel motor will work to cause the hanging slider to slide left and right on the linear rack. The movement of the hanging slider is controlled by changing the current direction of the travel motor, which not only simplifies the control logic, but also improves the timeliness of the reaction of the hanging slider.

[0020] The lifting ear of the present invention provides a connection point, so that the hook of the crane or other lifting equipment can firmly grasp the lifting slider, and provide a reference point for the subsequent flipping of the box-type component and the shifting of the center of gravity. The roller can ensure that the lifting slider moves along the path defined by the slide groove, preventing the traveling gear from deviating from the predetermined track. The rotating setting of the roller can also reduce the friction force. Compared with the lifting slider sliding directly in the slide groove, the rolling friction coefficient of the roller is much smaller than the sliding friction coefficient, thereby extending the service life of the lifting device.

[0021] During the operation of the driving motor of the present invention, the stroke of the double-headed hook chain is much greater than the stroke of the chain. By configuring a suitable gear ratio, the double-headed hook chain can assist the flipping of the box-type component. In order to prevent the double-headed hook chain from tearing off, a buffer can be added to one end of the hook. At the same time, the growth of the other end of the double-headed hook chain can fall off under the action of its own gravity, and there is no need for manual unhooking, thereby improving the convenience of lifting the box-type component.

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figure 1-Figure 9 As shown, the box-shaped large structural member lifting device with a flipping function provided in this embodiment comprises a T-shaped support arm 1, a suspension mechanism 2 is fixedly installed at the bottom end of the T-shaped support arm 1, a rotating seat 3 is rotatably arranged inside the suspension mechanism 2, a clamping plate module 4 is fixedly installed at the bottom end of the rotating seat 3 by bolts, two symmetrically distributed clamps 5 are slidably arranged on the bottom side of the clamping plate module 4, a box-shaped member 6 is fixedly arranged on the bottom side of the clamping head 5, and the clamping plate module 4 is used to drive the two clamping heads 5 to slide in opposite directions to clamp the upper end of the box-shaped member 6; A driving motor 7 is fixedly installed on one side of the T-shaped support arm 1, and a driving shaft 71 is fixedly installed on the output end of the driving motor 7. The driving shaft 71 passes through the T-shaped support arm 1 and extends to the other side of the T-shaped support arm 1. A first gear 72 is fixedly installed on the end of the driving shaft 71 away from the driving motor 7, and a chain 8 is meshed on the outer side of the first gear 72. A tooth groove 31 is fixedly provided on the side of the rotating seat 3 corresponding to the first gear 72, and the inner side of the end of the chain 8 away from the first gear 72 is meshed with the tooth groove 31; a second gear 73 is fixedly installed on the middle part of the driving shaft 71, and a double-headed hook chain 9 is meshed on the second gear 73. The double-headed hook chain 9 extends to both sides of the box-shaped component 6, and hooks 91 are fixedly provided on both ends of the double-headed hook chain 9. The double-headed hook chain 9 is hooked with the bottom side of the box-shaped component 6 through the hook 91. A hanging slider 10 is horizontally slidably provided on the upper end of the T-shaped support arm 1, and the sliding direction of the hanging slider 10 is opposite to the rotation direction of the rotating seat 3; Specifically, the driving motor 7 drives the first gear 72 and the second gear 73 to rotate through the driving shaft 71, and the first gear 72 rotates at the bottom end of the suspension mechanism 2 through the chain drive rotating seat 3, providing a basic rotational force to the clamping plate module 4, and then the second gear 73 generates a certain displacement through the meshing transmission double-head hook chain 9, and the double-head hook chain 9 generates a pulling force on the bottom side of the box-shaped component 6 through the hook 91. The double-head hook chain 9 cooperates with the clamping plate module 4 to reduce the load of the driving motor 7, thereby improving the flipping efficiency; Among them, the clamp module 4 is fixed on the bottom end of the rotating seat 3 by bolts, and the clamp 5 is driven by the clamp module 4 to fix the box-type component 6. The driving motor 7 drives the rotating seat 3 to rotate through the chain 8, and the rotating seat 3 drives the box-type component 6 to rotate, so that the box-type component 6 can be flipped 90 degrees left and right. During the rotation of the box-type component 6, the hanging slider 10 connected to the hook can slide left and right to balance the gravity of the T-shaped support arm 1 and the box-type component 6, so that the center of gravity of the T-shaped support arm 1 and the box-type component 6 is always directly below the hook, which can reduce the shaking amplitude of the lifting rope, thereby improving the installation accuracy and stacking efficiency of the box-type component 6.

[0026] In order to make the sliding direction of the hanging slider 10 opposite to the rotation direction of the rotating seat 3: like Figure 2-Figure 9 As shown, a slide groove 11 is provided on the T-shaped support arm 1, a linear rack 12 is fixedly arranged inside the slide groove 11, a travel motor 101 is fixedly installed inside the suspension slide block 10, a worm 102 is fixedly installed on the output end of the travel motor 101, a travel gear 103 is meshedly arranged on the bottom side of the worm 102, the bottom side of the travel gear 103 is meshed with the linear rack 12, the suspension slide block 10 is slidably arranged on the linear rack 12 through the travel gear 103, the travel motor 101 drives the travel gear 103 to rotate through the worm 102, and the travel gear 103 is meshed with the linear rack 12 during the rotation process, thereby making the suspension slide block 10 slide on the linear rack 12; At the same time, if Figure 2 , Figure 3 and Fig. 9 As shown, a hinge ring 13 is fixedly installed on the inner side of the suspension mechanism 2, a metal pendant 14 is rotatably installed on the hinge ring 13, the metal pendant 14 is rotatably installed above the hinge ring 13, the upper end of the metal pendant 14 is connected in series to the power circuit of the travel motor 101 through a wire, and protective plates 15 are fixedly installed on both sides of the metal pendant 14, and an electrode block 16 is fixedly installed on the inner side of the protective plate 15 corresponding to the metal pendant 14, and the two ends of the electrode block 16 are respectively electrically connected to the positive and negative poles of the power supply of the travel motor 101 through wires; During the rotation of the rotating seat 3, the center of gravity of the T-shaped support arm 1 and the box-shaped component 6 as a whole will shift, causing the T-shaped support arm 1 to tilt slightly. During the tilting of the T-shaped support arm 1, the metal hanging weight 14 will swing accordingly. The bottom end of the metal hanging weight 14 will contact the protective plate 15 to form a circuit of the travel motor 101. The travel motor 101 will work to make the hanging slider 10 slide left and right on the linear rack 12. Specifically, Figure 3 and Fig. 9 As shown, when the box-type component 6 flips clockwise, the left side of the T-shaped support arm 1 tilts downward under the action of gravity, the metal pendant 14 contacts the electrode block 16 on the left, and the travel motor 101 outputs in the positive direction to drive the hanging slider 10 to slide to the left. Conversely, when the box-type component 6 flips counterclockwise, the travel motor 101 outputs in the reverse direction to drive the hanging slider 10 to slide to the right, so that the hanging slider 10 is always directly above the box-type component 6. The movement of the hanging slider 10 is controlled by changing the current direction of the travel motor 101, which not only simplifies the control logic, but also improves the timeliness of the reaction of the hanging slider.

[0027] Further, such as Figure 7 and Fig. 9 As shown, a lifting ear 104 is fixedly installed on the upper end of the lifting slider 10, and the lifting ear 104 is used to hook with the hook of the lifting equipment. Rollers 105 are rotatably arranged on both sides of the lifting slider 10, and the rollers 105 are rotatably arranged inside the slide groove 11. The lifting ear 104 provides a connection point, so that the hook of a crane or other lifting equipment can firmly grasp the lifting slider 10, and provides a reference point for the subsequent flipping of the box-type component 6 and the displacement of the center of gravity. The rollers 105 can ensure that the lifting slider 10 moves along the path defined by the slide groove 11, and prevent the traveling gear 103 from deviating from the predetermined track. The rotation setting of the rollers 105 can also reduce friction. Compared with the lifting slider 10 directly sliding in the slide groove 11, the rolling friction coefficient of the rollers 105 is much smaller than the sliding friction coefficient, thereby extending the service life of the lifting device.

[0028] Furthermore, if Figure 4-Figure 6As shown, a machine position slot 41 is provided on the clamping plate module 4, and the rotating seat 3 is fixedly installed above the machine position slot 41 by bolts. Screw grooves 42 are provided on both sides of the clamping plate module 4 corresponding to the machine position slot 41, and a clamping motor 43 is fixedly installed inside the machine position slot 41, and an active bevel gear 44 is fixedly installed on the output end of the clamping motor 43; driven bevel gears 45 are meshedly connected on both sides of the active bevel gear 44, and a screw rod 46 is fixedly connected to the end of the driven bevel gear 45 away from the active bevel gear 44, and the screw rod 46 passes through the machine position slot 41 and the screw rod slot 42 and extends to the inner side wall of the screw rod slot 42. The two screw rods 46 are arranged inside the clamping plate module 4 through the machine position slot 41 to rotate in opposite directions, and a threaded slider 51 is fixedly arranged on the upper end of the chuck 5, and the threaded slider 51 extends to the inside of the screw rod slot 42, and the internal thread of the threaded slider 51 is meshed with the thread of the screw rod 46, and the chuck 5 is slidably arranged on the bottom side of the clamping plate module 4 through the threaded slider 51; Among them, the clamping motor 43 is the power source. During the operation of the device, the clamping motor 43 can provide torque. The active bevel gear 44 fixedly installed at its output end is mainly used to change the transmission direction and speed of power. The driven bevel gear 45 and the active bevel gear 44 drive the screw rod 46 to rotate. Since the two driven bevel gears 45 are arranged on both sides of the active bevel gear 44, the two screw rods 46 rotate in opposite directions, and the threaded slider 51 can move in the opposite direction. By controlling the rotation angle of the screw rod 46, the position of the chuck 5 can be accurately controlled, thereby realizing the precise control of the position of the box-type component 6 and realizing the grasping operation of the box-type component 6. At the same time, if Figure 6 As shown, a fixing plate 32 is fixedly connected to the bottom side of the rotating seat 3, and the fixing plate 32 is fixedly installed on the clamping plate module 4 by bolts. A dust cover 33 is fixedly arranged on the fixing plate 32, and the dust cover 33 corresponds to the clamping motor 43, ensuring that the connection between the rotating seat 3 and the clamping plate module 4 is firm and reliable and can withstand the torque when the rotating seat 3 rotates. The dust cover 33 fixedly arranged on the fixing plate 32 mainly functions to dissipate heat and prevent dust, impurities, etc. from entering the clamping motor 43, which is conducive to reducing maintenance costs and ensuring that the motor can work stably and efficiently.

[0029] In order to solve the problem that one end of the double-ended hook chain 9 is separated from the box-shaped member 6: like Figure 6 and Fig. 9 As shown, the two ends of the bottom side of the box-shaped member 6 are provided with hanging grooves 61, the hanging grooves 61 correspond to the hooks 91, the diameter of the second gear 73 is greater than the diameter of the first gear 72, and during the rotation of the rotating seat 3, the hook 91 away from the box-shaped member 6 is separated from the hanging groove 61, and the two sides of the T-shaped support arm 1 are fixedly installed with reinforcing ribs 17, and the reinforcing ribs 17 are rotatably provided with sub-gears 18, and the side of the double-head hook chain 9 away from the second gear 73 is meshed with the sub-gear 18; Among them, the diameter of the second gear 73 is larger than the diameter of the first gear 72, so the torque of the second gear 73 is larger, and the stroke of the edge of the second gear 73 is longer. Therefore, during the operation of the driving motor 7, the stroke of the double-headed hook chain 9 is much larger than the stroke of the chain 8. By configuring a suitable gear ratio, the double-headed hook chain 9 can assist the flipping of the box-type component 6. In order to prevent the double-headed hook chain 9 from tearing off one end of the hook 91, a buffer can be added. At the same time, the growth of the other end of the double-headed hook chain 9 can fall off under the action of its own gravity, and there is no need for manual unhooking, thereby improving the convenience of lifting the box-type component.

[0030] like Figure 1-Figure 9 As shown, the method for using the box-shaped large structural member lifting device with a flipping function provided in this embodiment includes the following steps: S1: First, the lifting lug 104 is connected to the lifting hook of the lifting device. The lifting slider 10 is located in the middle of the T-shaped support arm 1. The lifting device is started to transfer the T-shaped support arm 1 to the top of the box-shaped member 6, so that the bottom side of the clamp 5 is in contact with the upper end of the box-shaped member 6; S2: Then start the clamping motor 43 to drive the two driven bevel gears 45 to rotate in the opposite direction through the active bevel gear 44. At this time, the two screw rods 46 rotate in the opposite direction and drive the two chucks 5 to slide in the opposite direction through the threaded slider 51. The two chucks 5 clamp the box-shaped component 6 in the opposite direction and fix it. Start the lifting device to lift the box-shaped component 6. S3: When the box-shaped component 6 needs to be turned over for stacking, the driving motor 7 is started to drive the first gear 72 and the second gear 73 to rotate through the driving shaft 71, the first gear 72 drives the rotating seat 3 to rotate through the chain 8, and the rotating seat 3 drives the box-shaped component 6 to rotate toward one side of the T-shaped support arm 1 through the clamping plate module 4 and the clamp 5, and at the same time, the second gear 73 drives the hook 91 through the double-head hook chain 9 to generate lateral pulling force on the box-shaped component 6; S4: During the rotation of the rotating seat 3, the center of gravity of the T-arm 1 and the box-shaped component 6 as a whole will shift, causing the T-arm 1 to tilt. During the tilting of the T-arm 1, the metal hanging weight 14 will swing accordingly. The bottom end of the metal hanging weight 14 will contact the protective plate 15, which will form a circuit of the travel motor 101. The travel motor 101 drives the travel gear 103 to rotate through the worm 102, thereby causing the hanging slider 10 to slide on the linear rack 12, automatically adjusting the position of the hanging slider 10 and the center of gravity of the T-arm 1 and the box-shaped component 6 as a whole, so that the bottom end of the T-arm 1 tends to be vertical, and then the bottom end of the box-shaped component 6 tends to be horizontal; S5: When the box-shaped component 6 is hoisted to a suitable stacking position, the clamping motor 43 is started to drive the two clamps 5 to move away from each other through the active bevel gear 44, the driven bevel gear 45 and the screw rod 46, and the hook 91 is removed.

[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".
