Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer equipment technology, specifically to a batch transfer fixture for loading and unloading carbon blocks. Background Technology
[0002] Carbon blocks (or charcoal briquettes) are an important raw material and finished product in industries such as metallurgy and chemicals. Their production process involves multiple transfer stages, such as from the forming workshop to the roasting workshop, and then from the roasting workshop to the cleaning workshop or finished product warehouse. Currently, the transfer of carbon blocks within or between workshops usually relies on overhead cranes or forklifts equipped with simple lifting devices or forks.
[0003] However, existing transfer methods have many limitations: First, traditional lifting devices or forks can typically only grip a single or a few charcoal blocks at a time, resulting in low transfer efficiency. This cannot meet the cycle time requirements of modern large-scale production lines, becoming a bottleneck restricting production efficiency improvement. Second, charcoal blocks have smooth surfaces and hard textures, making them prone to slipping or even falling off due to inertia during transfer, especially during high-speed movement or start-stop operations. This poses significant safety hazards and may cause product damage. Furthermore, most simple clamps lack effective guiding and positioning mechanisms, making them prone to positional deviations during gripping and lowering. This requires operators to repeatedly adjust and align the blocks, increasing labor intensity and affecting positioning accuracy and operational safety. Utility Model Content
[0004] To address the aforementioned issues, this utility model provides a batch transfer fixture for loading and unloading carbon blocks, which has the advantages of wide applicability, stable operation, and high transfer efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a batch transfer fixture for loading and unloading carbon blocks, comprising a traveling trolley, a fixture assembly disposed below the traveling trolley, the fixture assembly comprising a discharge gripper and a transfer gripper, both the discharge gripper and the transfer gripper comprising a crossbeam, a support disposed below the crossbeam, gripping arms disposed at both ends of the support, a tensioning chain disposed in the middle of the support and connected to the crossbeam, and transmission arms disposed on both sides of the tensioning chain.
[0006] As a further improvement to the above technical solution: The traveling trolley is equipped with a winch connected to the clamp assembly, and the upper part of the crossbeam is equipped with a guide wheel assembly that works in conjunction with the winch.
[0007] The transmission arm includes a first cantilever hinged to the crossbeam and a second cantilever hinged to the bracket. A hinge shaft is provided between the first and second cantilevers. An extension arm hinged to the gripping arm is provided at the lower part of the second cantilever.
[0008] The upper part of the crossbeam is equipped with a guide locator connected to the traveling trolley, and the lower part is equipped with a guide sleeve. The bracket is equipped with a guide column that cooperates with the guide sleeve.
[0009] The guide positioner includes a positioning sleeve, with positioning rods on both sides of the positioning sleeve that are connected to the traveling trolley, and a movable guide post passing through the middle of the positioning sleeve.
[0010] The lower part of the gripping arm is provided with an anti-slip plate that fits against the surface of the material, and the back of the anti-slip plate is rotatably connected to the gripping arm.
[0011] The beneficial effects of this utility model embodiment are as follows: the batch transfer fixture for loading and unloading carbon blocks includes a traveling trolley, and a fixture assembly is provided below the traveling trolley. The fixture assembly includes unloading jaws and transfer jaws. Through the design of the fixture assembly, different transfer modes can be used, making the equipment suitable for more transfer scenarios. The drive system, which combines a tension chain and a transmission arm, can effectively and synchronously transmit the lifting force to the gripping arms on both sides, ensuring uniform and reliable gripping force. The end of the gripping arm is equipped with a rotatable anti-slip plate, which increases the friction with the surface of the carbon block and can adaptively conform to the surface of the material, effectively preventing slippage during the transfer process and ensuring operational safety. The dual guiding system of guide positioner, guide sleeve, and guide column ensures that the clamping assembly moves vertically along a predetermined trajectory during lifting, avoiding rotation and shaking, and ensuring accurate positioning.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0015] like Figures 1-5 As shown, the clamping assembly includes two functional units: an unloading clamp 2 and a transfer clamp 3. Both the unloading clamp 2 and the transfer clamp 3 adopt a unified structural design except for their dimensions: they include a crossbeam 6, with a support 4 below the crossbeam 6. Clamping arms 5 are symmetrically installed at both ends of the support 4. The middle of the support 4 is connected to the crossbeam 6 via a tension chain 7. On both sides of the tension chain 7, transmission arms 8 are installed, connected to the clamping arms 5. The transmission arms 8 drive the clamping arms 5 to retract inward, completing the clamping operation of the material. Then, a winch 9 and a traveling trolley are used to complete the lifting and transferring of the material.
[0016] The traveling trolley 1 is equipped with a winch 9 that drives the two grippers to lift and lower independently. The winch 9 is connected to the clamp assembly. The upper part of the crossbeam 6 is provided with a guide wheel assembly 10 that works with the winch 9. Through the coordinated action of the winch 9 and the guide wheel assembly 10, the lifting and lowering control of the clamp assembly can be realized.
[0017] The transmission arm 8 adopts a multi-link structure design, including a cantilever 11 hinged to the crossbeam 6 and a cantilever 2 12 hinged to the bracket 4. The cantilever 11 and the cantilever 2 12 are connected by a hinge shaft 13. To further enhance the force transmission effect, an extension arm 14 hinged to the clamping arm 5 is also provided at the lower part of the cantilever 2 12, forming a complete power transmission chain.
[0018] To ensure motion accuracy, a guide positioner 15 connected to the traveling trolley 1 is installed on the upper part of the crossbeam 6, and a guide sleeve 16 is installed on the lower part. Correspondingly, a guide post 17 is provided on the bracket 4 to cooperate with the guide sleeve 16. Through the sliding cooperation between the guide sleeve 16 and the guide post 17, the bracket 4 is ensured to move along the predetermined trajectory.
[0019] The guide positioner 15 adopts a precision guide structure, including a positioning sleeve 18. The two sides of the positioning sleeve 18 are fixed to the traveling trolley 1 through positioning rods 19, and the middle part is provided with a movable guide post 20 that can slide relative to each other, thereby providing a stable guiding function for the crossbeam 6.
[0020] To enhance the gripping effect, a slip plate 21 is provided at the lower part of the gripping arm 5. The working surface of the slip plate 21 is in contact with the material surface, while the back is rotatably connected to the gripping arm 5, which can ensure gripping stability and adapt to material surfaces of different shapes.
