Description

Technical Field

[0001] This utility model relates to the field of titanium alloy casting processing technology, specifically to a suspension chain for titanium alloy castings. Background Technology

[0002] Overhead conveyor chains are a type of overhead conveyor system that effectively utilizes space, saves manpower, and improves work efficiency. They are primarily composed of chains, tracks, lifting devices, supports, drive seats, and adjusting seats. They are widely used in long-distance workpiece conveying, floor lifting, overhead storage, material feeding, and automated coating production lines.

[0003] Currently, most overhead conveyor chains used for drying titanium alloy castings rely on connectors to secure the castings. Since titanium alloy castings vary in size, different connectors need to be changed during suspension to prevent the bottom of the casting from colliding and rubbing against surfaces or other objects. Changing connectors is cumbersome, and when there are many types of titanium alloy castings, frequent connector changes are necessary, leading to reduced drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a suspension chain for titanium alloy castings to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a suspension chain for titanium alloy castings, including a suspension chain body 1. A suspension unit is fixedly installed below the chain of the suspension chain body 1. The suspension unit includes a base plate 2, two connecting plates 3 and a hook 4. The hook 4 is detachably installed below the base plate 2. The two connecting plates 3 are fixedly installed below the chain of the suspension chain body 1. The bottom of each connecting plate 3 is fixedly connected to the top of the base plate 2 by a hanging ring.

[0023] A movable plate 5 is vertically and movably mounted on the base plate 2 via a height adjustment mechanism. A limiting plate 6 is fixedly installed at the bottom of the movable plate 5 at an angle, forming a groove 7 between the limiting plate 6 and the movable plate 5. A limiting rod 8 is fixedly installed on the side of the hook 4 and placed in the groove 7. There are two movable plates 5, which are fixedly connected by a horizontal plate 9. The height adjustment mechanism is located between the horizontal plate 9 and the movable plate 5. The height adjustment mechanism includes a threaded rod 10 and a knob 11. The threaded rod 10 passes through and is rotatably connected to the surface of the movable plate 5. The end of the threaded rod 10 is rotatably connected to the center of the horizontal plate 9. The knob 11 is fixedly installed. At the top of the threaded rod 10, each movable plate 5 is engaged with the base plate 2 through a limiting structure. The limiting structure includes a guide groove 12, a side plate 13, and a guide block 14. The two side plates 13 are fixedly installed on the two sides of the movable plate 5, and the guide block 14 is fixedly installed between the two side plates 13. Both side plates 13 are in contact with the surface of the movable plate 5. The guide groove 12 is provided on the surface of the base plate 2, and the guide block 14 is slidably connected to the inside of the guide groove 12. The hanging ring is set as an open lifting ring 16. The surfaces of the connecting plate 3 and the base plate 2 are provided with through holes 17. The open lifting ring 16 passes through the two through holes 17 to connect the connecting plate 3 and the base plate 2.

[0024] Please see Figure 1 , Figure 2 and Figure 3The connecting plate 3 is connected to the base plate 2 via a hanging ring to form a stable suspension support frame. This split design allows the hook 4 to be replaced individually without disassembling the entire suspension unit, significantly reducing maintenance difficulty. The two movable plates 5 are connected by a horizontal plate 9 to form a symmetrical support structure, ensuring that the base plate 2 is subjected to uniform force during height adjustment. The threaded rod 10 passes through the movable plate 5 and is connected to the horizontal plate 9. The threaded rod 10 is driven to rise and fall by rotating the top knob 11, achieving precise height adjustment of the movable plate 5. The threaded transmission method has both self-locking and convenient operation. The guide groove 12 and the guide block 14 slide together to restrict the movable plate 5 to move only in the vertical direction, avoiding skewing during adjustment. The contact surface between the side plate 13 and the base plate 2 provides frictional resistance, enhancing stability after adjustment. An open-type lifting ring is used to connect the base plate 2 and the connecting plate 3. During installation, the lifting ring does not need to be completely disassembled; only the opening needs to be opened for quick replacement or adjustment, significantly improving maintenance efficiency.

[0025] Specifically, the vertical height of the hook 4 to the bottom surface can be adjusted by rotating the knob 11, eliminating the need for frequent replacement of connectors to accommodate titanium alloy castings of different volumes. The operation is relatively simple. The suspension height of the hook 4 can be precisely adjusted by driving the movable plate 5 to rise and fall through the threaded rod 10. The V-shaped constraint structure formed by the limiting plate 6 and the groove 7 can suppress the lateral swing amplitude of the hook 4 during casting transportation, preventing casting collisions caused by chain shaking. The sliding contact design of the limiting rod 8 and the groove 7 allows the hook 4 to rise and fall freely in the vertical direction while restricting horizontal displacement, balancing flexibility and safety. The frame structure of the double movable plate 5 and the horizontal plate 9 makes the load distribution more uniform during height adjustment, and greatly increases the bending strength of the base plate 2.

[0026] The cross-section of the limiting rod 8 is circular. Limiting plates 6 are provided on both sides of the movable plate 5. A vertical rod 15 is fixedly installed on the top of the hook 4. The limiting rod 8 is horizontally fixedly installed on the surface of the vertical rod 15, and the vertical rod 15 is vertically set.

[0027] Please see Figure 3 and Figure 4 The bottom of the movable plate 5 is fixed with an inclined limiting plate 6 to form a groove 7. The limiting rod 8 is embedded in the groove 7. The inclined design of the limiting plate 6 and the groove 7 can apply lateral restraint to the hook 4 to prevent the hook 4 from colliding with the casting due to shaking during transportation. At the same time, the circular limiting rod 8 can reduce the contact stress with the groove 7 and reduce wear. It also allows the hook 4 to swing slightly in the groove 7 to adapt to the change of the center of gravity of the casting. The vertical rod 15 is vertically fixed to the top of the hook 4. The limiting rod 8 extends horizontally to form a T-shaped structure, which further enhances the stability of the hook 4. The hook 4 is detachably connected to the base plate 2 through the vertical rod 15. When replacing, it is only necessary to pull the limiting rod 8 out of the groove 7 to complete the disassembly.

[0028] Working principle: By rotating the knob 11, the threaded rod 10 is driven to rotate inside the base plate 2. At this time, the threaded rod 10 can drive the horizontal plate 9 to move vertically, so that the horizontal plate 9 drives the two movable plates 5 to move synchronously. The movable plates 5 can then drive the limiting rod 8 to move synchronously through the groove 7, thereby adjusting the height of the hook 4 from the ground. The height of the hook 4 can be adjusted by the knob 11 to accommodate titanium alloy castings of different volumes. Then, the titanium alloy casting is suspended on the hook 4, and the suspension chain body 1 can drive the titanium alloy casting to move sequentially through the connecting plate 3, the open lifting ring 16, the base plate 2, the movable plate 5, and the hook 4, so that the titanium alloy casting passes through the fan placed below the suspension chain body 1 to achieve rapid drying of the titanium alloy casting.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
