Description

Technical Field

[0001] This invention relates to the field of refrigerator handling technology, specifically to a hoisting device for handling refrigerators. Background Technology

[0002] Refrigerators, as large household appliances, are bulky and heavy. During production, warehousing, and logistics, they frequently require lifting equipment for handling, especially on production lines. While some existing lifting equipment can assist in handling, it often suffers from unstable clamping and poor adaptability when dealing with regularly shaped objects like refrigerators that require careful handling. Ordinary lifting devices may not be able to simultaneously meet the needs of lateral clamping and longitudinal restraint, leading to refrigerators easily shaking, rotating, or even slipping during lifting, posing a safety risk.

[0003] To address the aforementioned problems, we propose a hoisting device for refrigerator handling. Summary of the Invention

The clamping assembly includes two sets of clamping frames, which are respectively arranged on the lateral sides of the bottom end of the hoisting top plate. Two sets of insert plates are provided at the bottom of each clamping frame. A clamping plate is provided at the upper center of each insert plate, and the clamping plate is vertically mounted on the upper surface of the insert plate. A lifting assembly is provided on the back of each insert plate, which is used to drive the insert plate to move up and down. The limiting assembly includes two sets of limiting baffles, which are respectively arranged on the longitudinal sides of the bottom end of the hoisting top plate. A hydraulic rod is provided on the upper inner side of each limiting baffle, which is used to drive the limiting baffle to open and close. The driving component is used to drive the two sets of clamping frames and the two sets of limiting baffles to slide relative to each other synchronously, so that the two sets of clamping frames and the two sets of limiting baffles move closer to each other or further away from each other.

A second motor is installed in the inner center of the drive box. The output end of the second motor is connected to a worm gear through a gear assembly. Both sides of the worm gear are connected to bidirectional transmission screws through worm wheels. The two sets of bidirectional transmission screws are located in the middle of the two sets of clamping frames. The top of each set of clamping frames is provided with two sets of clamping sliding blocks. The two sets of clamping sliding blocks are respectively connected to the bidirectional transmission screws on both sides.

[0008] Preferably, the top of the clamping sliding block is provided with a first slider, the top of the first slider is slidably mounted with a first slide rail, and the first slide rail is fixedly mounted on the bottom end face of the hoisting top plate.

[0009] Preferably, each of the two sets of limiting baffles is provided with a limiting sliding block at its top, and each of the two sets of limiting sliding blocks is connected to a ball screw at the middle of its inner side. The two sets of ball screws are respectively installed at both ends of a worm gear and are arranged in opposite directions. The worm gear drives the ball screws at both ends to rotate synchronously, thereby driving the limiting sliding blocks at both ends to move closer to or further away from each other.

[0010] Preferably, the top of the limiting sliding block is provided with a second slider, and a second slide rail is slidably installed at the middle of the upper end of the second slider.

[0017] The technical solution in this application embodiment is to solve the problems in the background technology mentioned above. The overall idea is as follows: In the process of use, by setting clamping components and limiting components that are perpendicularly distributed to each other, the present invention can clamp and limit the refrigerator from both the horizontal and vertical sides at the same time, forming a stable three-dimensional constraint, which effectively prevents the refrigerator from shaking, rotating or slipping during hoisting, and greatly improves the safety and stability of handling operations.

[0018] Example: Refer to Figure 1 - Figure 6As shown, a hoisting device for transporting refrigerators according to this embodiment includes a hoisting top plate 1. The bottom end of the hoisting top plate 1 is provided with a clamping component and a limiting component. The clamping component and the limiting component are distributed vertically, that is, distributed in the horizontal and vertical directions, and surround the hoisting top plate 1 from all sides to form a stable hoisting space.

[0019] The clamping assembly includes two sets of clamping frames 2, which are respectively set on the horizontal sides of the bottom end of the hoisting top plate 1. Two sets of insert plates 3 are set at the bottom of the clamping frame 2, and a clamping plate 4 is set at the middle of the upper end of the insert plate 3. The clamping plate 4 is vertically installed on the upper surface of the insert plate 3. When clamping, the insert plate 3 can be inserted into the bottom of the refrigerator, and at the same time, the clamping plate 4 is close to the side of the refrigerator, forming a clamping and fixing of the bottom of the refrigerator, which enhances the stability during the hoisting process.

[0020] Furthermore, a lifting assembly is provided on the back of the insert plate 3. The lifting assembly is used to drive the insert plate 3 to move up and down. The lifting assembly includes a lifting transmission screw 5, which is movably installed at the bottom of the clamping frame 2. The lifting transmission screw 5 is connected to the back of the insert plate 3 for transmission. A first motor 6 is provided on the top of the lifting transmission screw 5. The first motor 6 is fixedly installed on the clamping frame 2. The first motor 6 is used to drive the lifting transmission screw 5 to rotate, thereby driving the insert plate 3 and the clamping plate 4 to move up and down to adapt to the bottom structure of the refrigerator of different heights.

[0021] The limiting assembly includes two sets of limiting baffles 12, which are respectively set on the longitudinal sides of the bottom end of the hoisting top plate 1. A hydraulic rod 14 is provided on the upper inner side of the limiting baffle 12. The hydraulic rod 14 is used to drive the limiting baffle 12 to open and close. When the limiting baffle 12 is in the unfolded state, the space left by the unfolded state allows the hoisting equipment to move from the side of the refrigerator to the position directly above the refrigerator and stop. Then, the hydraulic rod 14 retracts, causing the limiting baffle 12 to return to the vertical position, so that the limiting baffle 12 fits and contacts the outer surface of the refrigerator, forming a limiting and blocking effect.

[0022] The drive assembly is used to drive the two sets of clamping frames 2 and the two sets of limiting baffles 12 to slide relative to each other synchronously, so that the two sets of clamping frames 2 and the two sets of limiting baffles 12 move closer to each other or further away from each other. When the clamping frames 2 and the limiting baffles 12 are close together, the refrigerator inside can be clamped and limited on all four sides. Conversely, when the clamping frames 2 and the limiting baffles 12 are separated and far apart, a large amount of space is freed up, making it easy to remove the hoisting equipment from the refrigerator.

[0023] During use, the area enclosed by the two sets of clamping frames 2 and the two sets of limiting baffles 12 needs to be adjusted to match the size of the refrigerator to be hoisted and moved, so that when the clamping is closed, the clamping plate 4 and the limiting baffle 12 simultaneously come into contact with the outer wall of the refrigerator, thereby enhancing the stability of the refrigerator in longitudinal and lateral clamping and limiting.

[0024] The drive assembly includes a drive box 11, which is fixedly installed at the bottom center of the suspended top plate 1. A second motor 22 is installed in the inner center of the drive box 11. The output end of the second motor 22 is connected to a worm gear 19 via a gear assembly. Both sides of the worm gear 19 are connected to bidirectional transmission screws 7 via worm wheels 18. The two sets of bidirectional transmission screws 7 are located in the middle of the two sets of clamping frames 2. The top of each set of clamping frames 2 is provided with two sets of clamping sliding blocks 8. The two sets of clamping sliding blocks 8 are respectively connected to the bidirectional transmission screws 7 on both sides. When the second motor 22 starts, under the transmission force of the bidirectional transmission screws 7, the clamping sliding blocks 8 at both ends drive the clamping frames 2 at both ends to move closer or further away synchronously.

[0025] In some examples, a first slider 9 is provided on the top of the clamping sliding block 8, and a first slide rail 10 is slidably installed on the top of the first slider 9. The first slide rail 10 is fixedly installed on the bottom surface of the hoisting top plate 1. The first slider 9 and the first slide rail 10 serve to limit the sliding trajectory, thereby enhancing the stability and accuracy of the clamping frame 2 during the sliding process.

[0026] In some examples, the top of both sets of limiting baffles 12 is provided with limiting sliding blocks 13, and the inner middle of both sets of limiting sliding blocks 13 is connected to ball screws 17. The two sets of ball screws 17 are respectively installed at both ends of the worm gear 19 and are arranged in opposite directions. The worm gear 19 drives the ball screws 17 at both ends to rotate synchronously, thereby driving the limiting sliding blocks 13 at both ends to move the limiting baffles 12 closer to or further away from each other.

[0027] In some examples, a second slider 15 is provided on the top of the limiting sliding block 13, and a second slide rail 16 is slidably installed on the upper middle part of the second slider 15. The second slide rail 16 is fixedly installed on the bottom of the suspended top plate 1 and is installed perpendicular to the first slide rail 10. The second slide rail 16 and the second slider 15 limit the sliding trajectory of the limiting sliding block 13, thereby enhancing the stability of the limiting baffle 12 during the sliding process.

[0028] In some examples, the base of the hydraulic rod 14 is movably mounted at the bottom center of the limiting slide block 13, and the output end of the hydraulic rod 14 is movably connected to the inner end face of the limiting baffle 12.

[0029] In some examples, the worm gear 18 is fixedly mounted in the middle of the bidirectional transmission screw 7 and meshes with the worm 19.

[0030] In some examples, the gear assembly includes a transmission gear 20 and a drive gear 21. The transmission gear 20 is fixedly mounted in the middle of the worm gear 19, and the drive gear 21 is mounted at the output end of the second motor 22. The drive gear 21 is meshed with the transmission gear 20.

[0031] The working principle of this invention is: The hoisting equipment of this invention can be used on automated production lines. When in use, the hoisting top plate 1 needs to be installed on a mobile trolley on the automated production line. The mobile trolley can drive the hoisting equipment to move and slide on the track, so that the hoisting equipment can move to the storage area of ​​the refrigerator to clamp, hoist and transport the refrigerator.

[0032] When moving the refrigerator, first activate the drive assembly to move the clamping and limiting assemblies outward, expanding the internal space and providing sufficient room for the refrigerator to be placed inside. Simultaneously, activate the hydraulic rod 14 to push the limiting baffle 12 outward. (Refer to...) Figure 3 As shown, the limiting baffle 12 is in the open state, leaving enough height to facilitate the refrigerator entering the internal clamping space. At this time, the moving trolley can move the hoisting equipment from the longitudinal direction to the position directly above the refrigerator and place it. Then the drive assembly is started, and the worm gear 19 is driven to rotate by the second motor 22. Under the action of the worm wheel 18 and the bidirectional transmission screw 7, the clamping sliding blocks 8 on both sides drive the clamping frame 2 to move towards the center, so that the clamping frames 2 on both sides move closer to clamp the refrigerator from both sides. During the clamping process, the lifting assembly is activated, and the first motor 6 drives the lifting transmission screw 5 to rotate, thereby flexibly adjusting the height of the insert plate 3 so that the insert plate 3 can be inserted into the top of the refrigerator. As the clamping frame 2 continues to close and approach until the clamping plate 4 contacts the outer wall of the refrigerator, the front part of the insert plate 3 is completely inserted into the bottom of the refrigerator. Then, the first motor 6 is activated again, and the lifting transmission screw 5 rotates to drive the insert plate 3 to rise, thereby clamping and lifting the refrigerator, separating the refrigerator from the bottom tray or transport vehicle. Then, the hydraulic rod 14 retracts, driving the limit baffles 12 on both sides to close until the limit baffles 12 return to a vertical position. At this time, the limit baffles 12 fit against the outer surface of the refrigerator, thereby achieving longitudinal limiting and blocking of the refrigerator, thereby improving the stability of the clamping frame 2 on both sides for clamping and hoisting the refrigerator. Then, the moving trolley on the production line can move to carry the clamped refrigerator for hoisting and transportation.
