[0001] This utility model relates to the field of lifting hook clamp technology, and in particular to an anti-slip lifting hook clamp for lifting steel bars. Background Technology

[0002] Commonly used lifting hooks and clamps for steel bar hoisting include C-hooks, electric / hydraulic clamps, lever-type mechanical clamps, magnetic lifting tools, and flexible slings. When selecting, the load capacity should be matched according to the specifications of the steel bars, the hoisting method, and the frequency of operation, and the clamps should be designed with anti-slip teeth or safety locks to prevent slippage.

[0003] Traditional hook clamps, when in operation, the hook is hung on the crane or other lifting equipment to bear the weight of the entire system. The weight of the object being lifted is transmitted to the sling and hook through the clamping device. However, because secondary clamping is not possible, during the lifting process, due to equipment vibration, operational errors, or accidental collisions, the object being lifted may loosen or even fall off the clamp. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-slip hook clamp for lifting steel bars, which aims to improve the problem that traditional hook clamps cannot be used for secondary clamping, causing the lifted items to loosen or even fall off the clamp.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3 An embodiment of this utility model provides: a non-slip hook clamp for hoisting steel bars, including a support frame 1, a fixing ring 2 fixedly connected inside the support frame 1, a first support plate 3 fixedly connected to the lower surface of the support frame 1, a first protective shell 4 provided on the lower surface of the first support plate 3, a hydraulic cylinder 5 fixedly connected inside the first protective shell 4, a first sliding block 6 fixedly connected to the output end of the hydraulic cylinder 5, a rotating plate 7 rotatably connected inside the first sliding block 6, a second support plate 8 fixedly connected to the outer wall of the rotating plate 7, a fixing block 9 fixedly connected to the upper surface of the second support plate 8, and a clamping assembly 10 provided inside the rotating plate 7;

[0027] Specifically, the support frame 1 is used to support and fix the fixing ring 2. The support frame 1 and the fixing ring 2 have good strength and toughness, and can withstand the weight of the steel bars and their clamps during the hoisting process, as well as the dynamic load generated under different working conditions such as hoisting, running, and braking. The first support plate 3 is used to support and fix the fixing ring 2. The first support plate 3 is used to support and fix the first protective shell 4. The first protective shell 4 protects the internal structure from damage. The first protective shell 4 is used to support the stable operation of the hydraulic cylinder 5. The hydraulic cylinder 5 is used to drive the first sliding block 6 to slide. The first sliding block 6 rotates the rotating plate 7 under the action of the hydraulic cylinder 5. The first protective shell 4 is used to support and fix the fixing block 9. The fixing block 9 is used to support and fix the second support plate 8. The second support plate 8 is used to assist the rotating plate 7 in rotating. The rotating plate 7 is used to drive the first clamping plate 1001 to clamp. The first clamping plate 1001 is used to clamp the steel bars first.

[0028] Reference Figures 4-6 The clamping assembly 10 includes a first clamping plate 1001, the outer wall of which is fixedly connected to the inside of the rotating plate 7. A micro hydraulic rod 1002 is fixedly connected to the inside of the first clamping plate 1001. A second sliding block 1003 is fixedly connected to the output end of the micro hydraulic rod 1002. A first rotating rod 1004 is rotatably connected to the outer wall of the second sliding block 1003. A second clamping plate 1005 is fixedly connected to the inside of the first rotating rod 1004. The outer wall of the rotating plate 7 is rotatably connected to the inside of the first protective shell 4. The upper surface of the fixing block 9 is fixedly connected to the inside of the first protective shell 4. The outer wall of the second sliding block 1003 is slidably connected to the inside of the first clamping plate 1001. The outer wall of the first rotating rod 1004 is rotatably connected to the inside of the first clamping plate 1001. The outer wall of the second clamping plate 1005 is rotatably connected to the inside of the first clamping plate 1001.

[0029] Specifically, the first clamping plate 1001 is used to support the stable operation of the miniature hydraulic rod 1002 and to protect the internal structure from damage. The miniature hydraulic rod 1002 is used to drive the second sliding block 1003 to slide. The second sliding block 1003 is driven by the force of the miniature hydraulic rod 1002 to rotate the first rotating rod 1004. The first rotating rod 1004 is used to drive the second clamping plate 1005 to rotate. The second clamping plate 1005 is used to clamp the steel bar and prevent slippage, thereby achieving the effect of secondary clamping of the steel bar and preventing slippage, avoiding injury to personnel below, and preventing items from falling and damaging surrounding equipment, facilities or other products.

[0030] Reference Figures 4-6The first support plate 3 has a second protective shell 11 inside. The outer wall of the second protective shell 11 is located inside the first protective shell 4. The second protective shell 11 has a threaded channel 12 inside. A rotating block 13 is threadedly connected inside the threaded channel 12. The lower surface of the rotating block 13 is located on the upper surface of the first support plate 3. A protective ring 14 is fixedly connected to the outer wall of the second protective shell 11. A sliding rod 15 is slidably connected inside the second protective shell 11. A fixing plate 16 is fixedly connected to the outer wall of the sliding rod 15. A second rotating rod 17 is rotatably connected to the outer wall of the fixing plate 16. The outer wall of the second rotating rod 17 is located inside the first protective shell 4. A spring 18 is provided on the outer wall of the sliding rod 15. The bottom end of the spring 18 is located inside the second protective shell 11. The interior of the second protective shell 11 is slidably connected to the outer wall of the sliding rod 15.

[0031] Specifically, by rotating the rotating block 13, the connection between the first support plate 3 and the first protective shell 4 is loosened. The second protective shell 11 has a threaded channel 12 inside, which assists the second protective shell 11 in rotating. The second protective shell 11 supports the protective ring 14 for fixation. The protective ring 14 prevents foreign objects from causing the sliding rod 15 to slide. The sliding rod 15 drives the fixed plate 16 to slide. The fixed plate 16 drives the second rotating rod 17 to rotate. The sliding rod 15 drives the spring 18 to compress. The second protective shell 11 supports the spring 18 in compressing. When the sliding rod 15 is not pressed, the spring 18 prevents the sliding rod 15 from sliding accidentally through its own characteristics. When the sliding rod 15 is pressed, the spring 18 will cause the sliding rod 15 to spring back to its original position when the sliding rod 15 is released, thereby achieving the effect of changing the clamping device and reducing the risk of items falling during hoisting.

[0032] Working principle: When the anti-slip hook clamp for hoisting steel bars is needed, when the steel bars need to be clamped, the first sliding block 6 is driven to slide by the hydraulic cylinder 5, which in turn drives the rotating plate 7 to rotate. This causes the rotating plate 7 to rotate inside the second support plate 8. The inside of the rotating plate 7 drives the first clamping plate 1001 to rotate, thus clamping the steel bars first. Then, the micro hydraulic rod 1002 is driven to slide the second sliding block 1003, which in turn drives the first rotating rod 1004 to rotate, causing the second clamping plate 1005 to rotate. This achieves the effect of clamping the steel bars a second time and preventing slippage. It can reduce the risk of items falling and avoid injury to people below. It can also prevent items from falling and damaging surrounding equipment, facilities or other products, reducing economic losses and safety hazards.

[0033] When it is necessary to replace the clamping device, first rotate the rotating block 13 to loosen the connection between the first support plate 3 and the first protective shell 4. Then press the sliding rod 15 to drive the fixed plate 16 to slide, and at the same time drive the second rotating rod 17 to rotate, so that the spring 18 is compressed. This can achieve the effect of replacing the clamping device. Replacing with a suitable clamping device can better fix the suspended items and reduce the risk of items falling during the hoisting process.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
