Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and more specifically, it relates to a steel structure processing and hoisting clamp. Background Technology

[0002] Steel structure hoisting clamps are commonly used clamping equipment today, solving the inconvenience of traditional hoisting methods. However, they still have some drawbacks, making it difficult to effectively address the problems encountered in actual production in terms of workpiece stability and equipment versatility.

[0003] The primary problem is the low efficiency of gripping and moving steel components. The usual method is to use a robotic arm to grab them onto the workbench before proceeding to the next step of production. This method has disadvantages such as inconvenience in operation, high equipment cost, low production efficiency, and low adaptability. In addition, during hoisting, workers need to manually pull the traction chain to lift and lower the workpiece, which increases the workload of the workers.

[0004] More notably, the fixtures have low applicability, only able to clamp components of specific sizes. When encountering workpieces of different specifications, the fixtures need to be changed frequently, reducing efficiency. Adjustment is difficult; if the spacing between components changes or there are irregularly shaped parts, the fixtures cannot adapt to the changes, requiring manual intervention or additional auxiliary tools, increasing operational complexity. Forcibly clamping non-compliant workpieces can easily lead to unstable clamping, causing the risk of slippage or overturning.

[0005] Crucially, the limited range of fixture options can lead to several drawbacks. Workpieces are prone to slipping, shifting, and rotating due to their own weight, inertia, or slight external forces, resulting in uneven clamping forces that could cause them to fall off, threatening the safety of personnel and equipment. When lifting workpieces with smooth or irregular surfaces, the fixtures are difficult to hold securely, limiting their application. To compensate for the lack of stability, manual assistance is usually required for fixing, increasing labor intensity and time costs. Utility Model Content

[0033] Please see Figures 1-5A steel structure processing hoisting fixture includes a support frame 1 and an I-beam 2 fixedly connected to the support frame 1. The I-beam 2 is provided with a lateral movement mechanism and a hoisting mechanism. The hoisting mechanism is connected to a clamping mechanism. The lateral movement mechanism includes wheels 3, a connecting bracket 4, a rotary motor 5, and a first hook 6. Wheels 3 are rotatably connected to the connecting bracket 4 and the I-beam 2. The rotary motor 5 is fixedly connected to the connecting bracket 4 and rotatably connected to the wheels 3. The connecting bracket 4 is connected to the hoisting mechanism via the first hook 5. The clamping mechanism includes an auxiliary clamp and a main clamp. The auxiliary clamp includes two clamp bodies 7, a fixed column 8, a connecting handle 9, a second chain 10, and a lifting ring 11. The second chain 10 is connected to the lifting ring 11 and the connecting handle 9 respectively. The connecting handle 9 is rotatably connected to the clamp body 7 and the clamp body 7 is rotatably connected to the fixed column 8. The auxiliary clamp is connected to the hoisting mechanism via the lifting ring 11 and is movably connected to the main clamp via the fixed column 8.

[0034] In a further embodiment of this application, the main clamp includes a clamp base 12, a clamp body 13, a connecting body 14, a threaded post 15, a tightening head 16, a fixed base 17, a locking element 18, and a threaded sleeve 19. The fixed base 17 is fixedly connected to the fixed post 8 in the auxiliary clamp. The clamp body 13 is movably connected to the clamp base 12 through the slot of the clamp base 12. The connecting body 14 is movably connected to the threaded post 15 and the clamp body 13 respectively. The threaded sleeve 19 is connected to the threaded post 15 and fixedly connected to the fixed base 17. The fixed base 17 is detachably connected to the clamp base 12 through the locking element 18. The tightening head 16 is fixedly connected to the threaded post 15.

[0035] In a further embodiment of this application, the hoisting mechanism includes a lifting housing 20, a lifting motor 21, a drum 22, a first chain 23, and a second hook 24. The lifting housing 20 is fixedly connected to the first hook 6 and the lifting motor 21. The drum 22 is rotatably connected to the lifting housing 20 and the lifting motor 21. The first chain 23 is connected to the drum 22 and the second hook 24 is fixedly connected to the second hook 24. The second hook 24 is connected to the lifting ring 11 in the auxiliary clamp.

[0036] In a further embodiment of this application, the fixture base 12 is provided with an adjustment hole 25, which is movably connected to the fixed base 17 and the locking member 18. When it is necessary to adjust the distance between the clamping bodies 13 in the main fixture according to the size of the workpiece, the locking member 18 is disassembled to separate the fixed base 17 from the fixture base 12. Then, the clamping body 13 is dragged to the required approximate position, and then the threaded sleeve 19 is rotated around the threaded post 15 for fine adjustment. After aligning the fixed base 17 with the adjustment hole 25, it is fixed with the locking member 18 to complete the adjustment of the distance between the clamping bodies 13.

[0037] In a further embodiment of this application, the support frame 1 is provided with casters 26, making the entire device movable.

[0038] In a further embodiment of this application, the hoisting mechanism is provided with an operating handle 27, which increases the ease of operation of the hoisting mechanism.

[0039] In a further embodiment of this application, the clamp body 7 of the auxiliary clamp is provided with an anti-slip block 28 to ensure the stability of the clamping.

[0040] In a further embodiment of this application, the first hook 6 and the second hook 24 are provided with an anti-detachment baffle 29 and an elastic body 30. The elastic body 30 is fixedly connected to the first hook 6 or the second hook 24 and the anti-detachment baffle 29, respectively. When an object is loaded into the hook, the object exerts a force on the anti-detachment baffle 29 and compresses the elastic body 30, causing the anti-detachment baffle 29 to separate from the hook, and the object can then enter the hook. After the object enters, it no longer exerts a force on the anti-detachment baffle 29. The anti-detachment baffle 29 is in contact with the hook due to the elastic force of the elastic body 30. The anti-detachment baffle 29 has unidirectional properties and can prevent the object from accidentally detaching from the hook.

[0041] In this embodiment, when the device is needed, the support frame 1 is dragged to the working position via the casters 26. The rotary motor 5 on the connecting bracket 4 of the hoisting mechanism is started by operating the handle 27. The rotary motor 5 rotates, causing the wheels 3 to move on the I-beam 2, bringing the hoisting mechanism above the workpiece. Then, the lifting motor 21 on the lifting housing 20 is started by operating the handle 27. The lifting motor 21 rotates, causing the drum 22 to rotate, gradually separating the first chain 23 from the drum 22, placing the clamping mechanism above the workpiece. The workpiece is placed in the clamp 13, and the tightening head 16 is rotated, causing the threaded post 15 to rotate around the threaded sleeve 19 and the connecting body 14. The fixing seat 17 and the locking element 18 are fixed on the clamping seat 12 to provide a secure grip for the threaded post 15. A fixed support force is applied, causing the threaded post 15 to extend towards the workpiece, pushing the clamping body 13 to slide within the clamping seat 12. The clamping body 13 gradually clamps the workpiece and is locked by the fixed seat 17 and the threaded sleeve 19, completing the workpiece clamping operation. Then, the lifting motor 21 is started, causing the drum 22 to wind the first chain 23 tightly, raising the second hook 24. The rising of the second hook 24 drives the lifting ring 11 and the second chain 10 to rise. Under the influence of gravity, the rising of the second chain 10 causes the connecting handles 9 to move closer together, causing the clamping body 7 to rotate around the fixed post 8, clamping the working end of the clamping body 7. The anti-slip block 28 provided at the working end can effectively prevent the workpiece from sliding, completing the auxiliary clamping of the workpiece. At the same time, the second hook 24 and the clamping mechanism rise to lift the workpiece, completing the clamping and movement of the workpiece.

[0042] More specifically, when it is necessary to adjust the distance between the clamping bodies 13 in the main fixture according to the size of the workpiece, the locking member 18 is disassembled to separate the fixed seat 17 from the fixture seat 12. Then, the clamping body 13 is dragged to the required approximate position, and the threaded sleeve 19 is rotated around the threaded column 15 for fine adjustment. After aligning the fixed seat 17 with the adjustment hole 25, it is fixed with the locking member 18 to complete the adjustment of the distance between the clamping bodies 13. In addition, when the object is loaded into the hook, the object applies force to the anti-disengagement baffle 29 and compresses the elastic body 30, causing the anti-disengagement baffle 29 to separate from the hook, and the object can then enter the hook. After the object enters, it no longer applies force to the anti-disengagement baffle 29. The anti-disengagement baffle 29 is in contact with the hook due to the elastic force of the elastic body 30. The anti-disengagement baffle 29 has unidirectional properties and can prevent the object from accidentally disengaging from the hook.

[0043] In summary, when using or operating the overall equipment: When the equipment needs to be used, the support frame 1 is dragged to the working position via the casters 26. The rotary motor 5 on the connecting bracket 4 of the hoisting mechanism is started by operating the handle 27. The rotary motor 5 rotates, causing the wheels 3 to move on the I-beam 2, bringing the hoisting mechanism above the workpiece. Then, the lifting motor 21 on the lifting housing 20 is started by operating the handle 27. The lifting motor 21 rotates, causing the drum 22 to rotate, gradually separating the first chain 23 from the drum 22, placing the clamping mechanism above the workpiece. The workpiece is placed in the clamp body 13. The tightening head 16 is rotated, causing the threaded column 15 to rotate around the threaded sleeve 19 and the connecting body 14. The fixed seat 17 and the locking element 18 are fixed on the clamp seat 12 as the threaded column. 15 provides a fixed support force, causing the threaded post 15 to extend towards the workpiece and push the clamping body 13 to slide within the clamping seat 12. The clamping body 13 gradually clamps the workpiece and is locked by the fixed seat 17 and the threaded sleeve 19, completing the workpiece clamping work. Then, the lifting motor 21 is started, causing the drum 22 to wind the first chain 23 tightly, causing the second hook 24 to rise. The rise of the second hook 24 drives the lifting ring 11 and the second chain 10 to rise. Under the influence of gravity, the rise of the second chain 10 causes the connecting handles 9 to move closer to each other, causing the clamping body 7 to rotate around the fixed post 8, so that the working end of the clamping body 7 clamps. The anti-slip block 28 provided at the working end can effectively prevent the workpiece from sliding, completing the auxiliary clamping of the workpiece. At the same time, the second hook 24 and the clamping mechanism rise to lift the workpiece, completing the clamping and movement of the workpiece.

[0044] When it is necessary to adjust the distance between the clamping bodies 13 in the main fixture according to the size of the workpiece, the locking member 18 is disassembled to separate the fixed seat 17 from the fixture seat 12. Then, the clamping body 13 is dragged to the required approximate position, and the threaded sleeve 19 is rotated around the threaded column 15 for fine adjustment. After aligning the fixed seat 17 with the adjustment hole 25, it is fixed with the locking member 18 to complete the adjustment of the distance between the clamping bodies 13. In addition, when the object is loaded into the hook, the object applies force to the anti-disengagement baffle 29 and compresses the elastic body 30, causing the anti-disengagement baffle 29 to separate from the hook, and the object can enter the hook. After the object enters, it no longer applies force to the anti-disengagement baffle 29. The anti-disengagement baffle 29 is in contact with the hook due to the elastic force of the elastic body 30. The anti-disengagement baffle 29 has unidirectional properties and can prevent the object from accidentally disengaging from the hook.

[0045] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
