Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and clamping, in particular to a hoisting and clamping device. Background Art

[0002] In the process of house decoration, various types of building materials are needed and the materials need to be transported to the appropriate area. Some materials such as steel and pipes need to be transported using lifting equipment. In order to ensure the stability of such materials during the lifting process, clamps are needed to clamp and fix the materials.

[0003] At present, when the existing lifting clamps are used, the staff will first hang the lifting ring connected to the top of the clamp on the hook of the lifting equipment. Since the inner diameter of the lifting ring is relatively large, when the lifting equipment is used for lifting outdoors and encounters strong winds, the lifting ring hanging on the hook is easily shaken by the wind, which can easily cause the material clamped by the clamp to tilt or even fall. There is a great safety hazard when using it. For this reason, we propose a lifting clamping device to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a hoisting clamping device.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The lifting device comprises a clamp 1, a lifting ring 2 is connected to the top of the clamp 1, and the lifting ring 2 is engaged in the hook 3. The hook 3 is a part of the lifting equipment, which can drive the lifting ring 2 to complete the lifting and transportation of the material. The specific clamping principle of the lifting ring 2 is the existing technology, which will not be described in detail here. The bottom end of the lifting ring 2 is provided with a receiving groove 4, and the inner wall of the receiving groove 4 is connected with a two-way threaded rod 5 through a bearing. The outer side of the two-way threaded rod 5 is symmetrically connected with a sleeve with a threaded sleeve 6, and the top of the threaded sleeve 6 is connected to a first limit plate 8 through a connecting rod 7. The inside of the lifting ring 2 is provided with a slideway adapted to the connecting rod 7. The outer side of the two-way threaded rod 5 is provided with two groups of external threads in opposite directions, and the internal threads of the two groups of threaded sleeves 6 sleeved on the outer side of the two-way threaded rod 5 are also opposite. Therefore, when the two-way threaded rod 5 rotates, the two groups of threaded sleeves 6 are subjected to force and slide in the inside of the receiving groove 4 at the same time. Through the mutual cooperation of the connecting rod 7 and the slideway, the normal movement of the first limit plate 8 in the lifting ring 2 can be satisfied.

[0023] Further, see Figure 2 It can be known that a buffer pad 10 is glued to the inner wall of the top end of the lifting ring 2, and the buffer pad 10 is arranged as an arc structure. The buffer pad 10 arranged by the arc structure can effectively prevent the outer wall of the hook 3 from being directly rigidly connected with the inner wall of the lifting ring 2, thereby realizing the protection of the lifting ring 2 and the hook 3 at the same time, so as to effectively prevent the hook 3 and the lifting ring 2 from being worn.

[0024] Further, see Figure 2 and Figure 3 It can be known that the left side of the bidirectional threaded rod 5 extends to the outside of the lifting ring 2 and is connected to a rotating block 9, and rotating columns are equidistantly distributed on the outside of the rotating block 9. When in use, the cooperation between the rotating block 9 and the rotating column can facilitate the staff to quickly rotate the bidirectional threaded rod 5, thereby effectively improving the convenience of using the device.

[0025] Further, see Figure 2 and Figure 3It can be known that a cylinder 11 is installed inside the lifting ring 2, and the bottom end of the cylinder 11 extends to the inner wall of the lifting ring 2 and is connected to a pushing block 12. The inner wall of the lifting ring 2 is provided with a movable groove adapted to the pushing block 12, and the side of the pushing block 12 is connected to a second limiting plate 13. A rectangular groove adapted to the second limiting plate 13 is provided inside the first limiting plate 8. The telescopic principle of the cylinder 11 is the existing technology, which can drive the second limiting plate 13 to move up and down smoothly inside the lifting ring 2, thereby realizing the limitation of the vertical range of the hook 3 to further prevent the lifting ring 2 from shifting during the hanging process.

[0026] Further, see Figure 3 It can be known that the inner wall of the lifting ring 2 is vertically connected with a guide rod 14, and a hole compatible with the guide rod 14 is opened on the left side of the second limiting plate 13. The second limiting plate 13 can be guided by the guide rod 14 and the hole opened inside the second limiting plate 13 to ensure the stable sliding of the second limiting plate 13.

[0027] Further, see Figure 1 It can be seen that the bottom end of the clamp 1 is symmetrically distributed with clamps 15, and the outer surface of the clamp 15 is glued with a rubber sheet. The clamp 15 with a larger cross-sectional area and the setting of the rubber sheet can ensure the clamping effect of the material.

[0028] Further, see Figure 3 It can be known that the outer surfaces of the first limiting plate 8 and the second limiting plate 13 are glued with anti-skid pads, and the outer walls of the anti-skid pads are evenly distributed with rubber particles. The anti-skid pads and anti-skid particles arranged on the first limiting plate 8 and the second limiting plate 13 can effectively prevent the first limiting plate 8 and the second limiting plate 13 from directly and rigidly contacting the hook 3, so as to protect the hook 3 and the second limiting plate 13.

[0029] Working principle: When the utility model is in use, the staff can first hang the lifting ring 2 on the hook 3, and then rotate the rotating block 9, thereby driving the two-way threaded rod 5 to rotate at the same time. Since the outer side of the two-way threaded rod 5 is provided with two sets of external threads with opposite thread directions, when the two-way threaded rod 5 rotates, it will drive the two sets of threaded sleeves 6 to move in opposite directions and slide inside the accommodating groove 4. When the threaded sleeves 6 move, the two sets of first limit plates 8 are forced to move at the same time and gradually approach and abut against the outer wall of the hook 3. Then the staff can stop rotating the rotating block 9, and then Start the cylinder 11 to drive the second limit plate 13 to move up. The rectangular groove provided inside the first limit plate 8 can ensure the normal movement of the second limit plate 13. When the upper side of the second limit plate 13 is moved to fit the outer wall of the bottom end of the hook 3, the cylinder 11 stops pushing, thereby limiting the vertical range of the hook 3. The lateral range limitation of the two groups of first limit plates 8 can effectively prevent the lifting ring 2 from swinging on the hook 3 due to the action of wind, so as to effectively ensure the stability of the clamp 1 when clamping the material. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
