Description

Technical Field

[0001] This utility model relates to the field of industrial material hoisting technology, and in particular to a single-point quick-connection and disassembly anti-sway mechanism. Background Technology

[0002] In the field of industrial material lifting, the connection between the hook and the lifting device is very simple in the case of a single lifting point. Typically, the lifting lugs on the lifting device are simply fitted onto the hook, and then the lifting and lowering of the hook drives the lifting device to lift the material. However, this existing method of directly connecting the hook and the lifting device has the following drawbacks during the lifting process: Since the lifting gear is directly attached to the hook through the lifting lugs, the lifting gear will sway relative to the hook during lifting, lowering and moving. This will cause the material to sway when being lifted, thus posing a significant safety hazard during the lifting process. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0004] Therefore, one objective of this utility model is to propose a single-point quick connection and disassembly anti-sway mechanism, which aims to solve the problem that the lifting device may sway relative to the hook in the prior art, resulting in safety hazards.

[0005] To achieve the above objectives, one embodiment of the present invention provides a single-point quick-connect and disassembly anti-sway mechanism, including a lifting device and a hook. Two symmetrical support plates are installed on both sides of the hook. Two symmetrical hanging plates are fixedly connected to the top of the lifting device, and a hanging rod is fixedly connected between the two hanging plates. The hook is sleeved on the outer surface of the hanging rod, and two symmetrical connecting plates are connected between the support plate and the hanging plate on the same side.

[0006] The beneficial effects are as follows: the connecting plate on the support plate supports the hanging plate, so that the hanging rod will not move inside the hook. Therefore, during the lifting process, the lifting tool will not sway relative to the hook. When lifting materials, the material can be quickly restored to stability, avoiding the problem of materials falling due to excessive shaking, thus improving safety.

[0007] In a preferred embodiment, the top of the connecting plate is rotatably connected to the side of the support plate, the bottom of the connecting plate is provided with a positioning groove, and a positioning block is fixedly connected to the outside of the hanging plate, with the positioning groove sleeved on the outer surface of the positioning block.

[0008] Furthermore, a positioning strip is fixedly connected to the outer side of the connecting plate, a sliding groove is provided on the top of the positioning strip, a C-shaped slide bar is slidably connected to the outer surface of the positioning strip, and a limit rod is fixedly connected to one side of the bottom of the C-shaped slide bar.

[0009] The beneficial effects are as follows: When changing lifting devices for different materials, simply tilt and slide the C-shaped slide bar upwards, then rotate the connecting plate upwards to separate the connecting plate from the lifting plate. Finally, remove the hook from the hanging rod to complete the disassembly. Then, the reverse operation can be performed to replace the new lifting device. Therefore, it has the advantage of quick disassembly and assembly of lifting devices, and can improve the efficiency of material lifting when transporting various materials.

[0010] Furthermore, a limiting plate is fixedly connected to the outer side of the positioning block, and a positioning hole is provided inside the positioning groove at the position corresponding to the limiting rod.

[0011] The beneficial effects are as follows: the limiting plate can limit the bottom of the connecting plate, which can prevent the connecting plate from bending outward under force, causing the positioning groove to detach from the positioning block. The limiting rod is inserted into the positioning hole, which can support the end of the limiting rod and avoid the problem of the limiting rod bending under force.

[0012] In a preferred embodiment, symmetrical limiting shafts are fixedly connected to both sides of the hook, and a positioning shaft is fixedly connected to the end of the limiting shaft. A circular hole is provided at the center of the support plate, and the support plate is sleeved on the outer surface of the positioning shaft through the circular hole. A limiting groove is provided on the outer surface of the positioning shaft, and a positioning plate is installed on the outer side of the support plate by bolts, and the positioning plate is stuck inside the limiting groove.

[0013] Furthermore, it also includes two support rods, each of which is fixedly connected to a plug rod at both ends. The support plate has a plug hole on its side, and the plug rod is inserted into the plug hole. The end of the plug rod is fixedly connected to a round shaft. The top of the connecting plate has a sleeve hole, and the connecting plate is rotatably sleeved on the outer surface of the round shaft through the sleeve hole.

[0014] Furthermore, a limiting plate two is fixedly connected to the end of the circular shaft, and a notch one adapted to the limiting plate two is opened on the inner wall of the insertion hole, and a notch two adapted to the limiting plate two is opened on the inner wall of the sleeve hole.

[0015] The beneficial effects are as follows: After the two support rods are placed between the two support plates and the positioning plate fixes the two support plates to the hook, the connecting plate is directly fitted onto the outer surface of the round shaft through the sleeve hole and notch two. Then, the connecting plate is rotated to make notch two and limit plate two misaligned, thus making the disassembly and assembly of the anti-sway mechanism simple.

[0016] In a preferred embodiment, the side of the connecting plate is provided with a slot, and connecting rods are inserted into the slots of the two opposite connecting plates. Both ends of the connecting rods are fixedly connected with screws, and the outer surface of the screws is threaded with nuts.

[0017] The beneficial effects are as follows: the nuts at both ends of the connecting rod can fix the distance between the two opposite connecting plates, so that when the lifting device is disassembled, the connecting plate can be rotated upwards and the notch two is aligned with the limit plate two, and the connecting plate will not fall off, thereby improving the stability of the structure.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides a single-point quick-connection and disassembly anti-sway mechanism. Example 1:

[0029] like Figure 1-2 As shown, it includes a lifting device 1, a hook 2, two support plates 3 and four connecting plates 5. The hook 2 is a hook on the lifting equipment that is connected to the wire rope. The two support plates 3 are symmetrically installed on both sides of the hook 2. Two symmetrical hanging plates 4 are welded to the top of the lifting device 1, and a hanging rod 41 is welded between the two hanging plates 4. The hanging rod 41 is suspended inside the hook 2 and is used to lift or lower the lifting device 1.

[0030] like Figure 1 As shown, four connecting plates 5 are arranged in pairs, with the two sets of connecting plates 5 symmetrically arranged on the outside of the two support plates 3 and the two hanging plates 4. The two connecting plates 5 in each set are symmetrically arranged, and the top of the connecting plate 5 is rotatably connected to the side of the support plate 3. The connecting plate 5 has a positioning groove 51. The outside of the hanging plate 4 is welded with a positioning block 42. The connecting plate 5 rotates around the connection point with the support plate 3 and can be fitted onto the outer surface of the positioning block 42 through the positioning groove 51. The outside of the positioning block 42 is welded with a limit plate 43 to prevent the connecting plate 5 from bending outward under force, which would cause the positioning groove 51 to detach from the positioning block 42.

[0031] like Figure 3 As shown, a positioning strip 53 is welded to the outer side of the connecting plate 5. A groove 54 is provided on the top of the positioning strip 53. A C-shaped slide bar 6 is slidably connected to the outer surface of the positioning strip 53. A limit rod 61 is welded to one side of the bottom of the C-shaped slide bar 6. When the C-shaped slide bar 6 is slid down, the limit rod 61 can close the opening of the positioning groove 51, thereby preventing the connecting plate 5 from rotating upward due to vibration, which would cause the positioning groove 51 to detach from the positioning block 42. Furthermore, a positioning hole 52 is provided inside the positioning groove 51 at a position corresponding to the limit rod 61. The end of the limit rod 61 is inserted into the positioning hole 52, which improves the rigidity of the limit rod 61 and avoids the problem of the limit rod 61 bending under force.

[0032] The working principle of this embodiment is as follows: In use, the hook 2 of the lifting equipment is fitted onto the surface of the hanging rod 41 on the lifting device 1. Then, the connecting plate 5 is rotated so that the positioning groove 51 is fitted onto the outer surface of the positioning block 42, and the C-shaped slide bar 6 is slid downwards at an angle so that the limiting rod 61 closes the opening of the positioning groove 51, thereby completing the connection between the lifting device 1 and the lifting equipment. The lifting device 1 can be quickly disassembled by reversing the operation, which facilitates the disassembly and assembly of the lifting device 1. When the lifting equipment lifts the lifting device 1, the four connecting plates 5 support the hanging plate 4, so that the hanging rod 41 cannot rotate inside the hook 2, thereby avoiding the problem of the lifting device 1 swaying relative to the hook 2. When lifting materials, the stability of the materials can be quickly restored, avoiding the problem of materials falling due to excessive shaking. Example 2:

[0033] like Figure 4-5 As shown, based on Embodiment 1, symmetrical limiting shafts 21 are welded on both sides of the hook 2. The end of the limiting shaft 21 is provided with a positioning shaft 22 with a diameter smaller than the limiting shaft 21. A circular hole 31 with a diameter smaller than the limiting shaft 21 is opened at the center of the support plate 3. The support plate 3 is sleeved on the surface of the positioning shaft 22 through the circular hole 31, and the limiting shaft 21 supports the inner side of the support plate 3.

[0034] A limiting groove 23 is provided on the outer surface of the positioning shaft 22. The positioning plate 8 is inserted into the limiting groove 23. A through hole is provided on the positioning plate 8. A threaded hole is provided on the support plate 3 at the position corresponding to the through hole. By using a bolt to pass through the through hole and threadedly connect with the threaded hole, the positioning plate 8 can be fixed to the side of the support plate 3. The positioning plate 8 can position the support plate 3 so that it cannot slide out of the positioning shaft 22.

[0035] like Figure 5 As shown, two support rods 7 are also provided between the two support plates 3. The two support rods 7 support the interior of the two support plates 3 on both sides to prevent the two support plates 3 from bending and deforming inward. Square insertion rods 71 ​​are welded to both ends of the support rods 7. Square insertion holes 32 are opened on the side of the support plates 3. After the insertion rods 71 ​​are inserted into the insertion holes 32, the support rods 7 cannot rotate. A round shaft 72 is fixedly connected to the end of the insertion rod 71. The round shaft 72 protrudes from the outside of the support plates 3. A limit plate 73 is fixedly connected to the end of the round shaft 72, and the inner wall of the insertion hole 32 is provided with a limit plate 73. The limiting plate 73 has a notch 33 that matches the positioning plate 73. When the insertion rod 71 is inserted into the insertion hole 32, the limiting plate 73 passes through the supporting plate 3 through the notch 33. The top of the connecting plate 5 has a sleeve hole 55, and the inner wall of the sleeve hole 55 has a notch 56 that matches the limiting plate 73. When the connecting plate 5 is fitted onto the outer surface of the round shaft 72, the limiting plate 73 passes through the connecting plate 5 through the notch 56. Then, by rotating the connecting plate 5 around the round shaft 72, the notch 56 can be misaligned with the limiting plate 73, so that the limiting plate 73 can limit the connecting plate 5.

[0036] The working principle of this embodiment is as follows: During assembly, firstly, a support plate 3 is placed on the positioning shaft 22 on one side of the hook 2, and then the support plate 3 is positioned by the positioning plate 8. Then, two support rods 7 are inserted into the support plate 3, and another support plate 3 is placed on the positioning shaft 22 on the other side of the hook 2, with the insertion hole 32 corresponding to the other end of the support rod 7. Then, the positioning plate 8 is used to position the second support plate 3, thereby completing the assembly of the two support plates 3. The connecting plate 5 is directly fitted onto the outer surface of the round shaft 72 through the sleeve hole 55 and the notch 56. Then, the connecting plate 5 is rotated to make the notch 56 and the limiting plate 73 misaligned. Thus, the installation of the connecting plate 5 does not require conventional fixing structures such as bolts, and the assembly is very simple. Example 3:

[0037] like Figure 6 As shown, based on Embodiment 2, it also includes a connecting rod 9. The side of the connecting plate 5 has a hole and groove 57. The connecting rod 9 passes through the two opposite connecting plates 5 through the hole and groove 57. Then, nuts 92 are connected to the surfaces of the screws 91 at both ends of the connecting rod 9 to fix the distance between the two opposite connecting plates 5. This avoids the problem that the connecting plate 5 will fall off when the notch 56 aligns with the limiting plate 73 during the disassembly of the lifting device 1.
