Abstract
Description
Technical Field
[0001] This application relates to the technical field of workpiece hoisting, and in particular to a hoisting fixture. Background Technology
[0002] Hot isostatic pressing (HIP) is a special heat treatment process for metallic or ceramic materials and an important means of preparing high-performance materials. Currently, HIP sintering technology is also one of the core technologies for target material preparation. The hot isostatic pressing process involves placing the product in a sealed container, applying isotropic pressure to the product, and simultaneously applying high temperature. Under the action of high temperature and high pressure, the product is sintered and densified.
[0003] In the hot isostatic pressing (HIP) workshop, lifting equipment is an indispensable auxiliary tool. Nickel-chromium alloy charging hoppers are frequently used during furnace loading. These hoppers are circular with walls exceeding 40mm in thickness, making them quite heavy. The weight increases even further when the hopper is full. When removing products from the HIP furnace, the charging hopper must be lifted, ensuring balance and preventing tilting, which could cause the product to collide with the hopper wall. Furthermore, uneven stress during repeated lifting can cause deformation of the hopper, affecting the amount of product loaded into the furnace. Utility Model Content
[0004] To reduce barrel deformation, this application provides a lifting fixture.
[0005] This application provides a lifting fixture, which adopts the following technical solution:
[0006] A hoisting fixture includes a support frame and hooks mounted on the support frame. There are at least three hooks, each hook including a support rod and an insertion rod connected to the support rod. A loading hopper has an insertion hole for the insertion rod to be inserted into. The support rod is detachably mounted on the support frame.
[0007] By adopting the above technical solution, the lifting fixture includes at least three hooks. With more than three hooks attached to the periphery of the loading barrel, the deformation of the loading barrel is reduced when it is lifted. The design of the hooks allows the insertion rod to be inserted into the insertion hole of the loading barrel, which enhances the stability and ease of lifting. At the same time, the support rod can be detachably installed on the support frame, which makes it easy to adjust the number and position of the hooks according to actual needs, thus improving the flexibility and adaptability of the fixture.
[0008] Optionally, the support frame includes a ring, and the inner wall of the ring is connected to multiple reinforcing ribs. The reinforcing ribs are arranged along the radial direction of the ring, and the multiple reinforcing ribs are fixedly connected to each other.
[0009] By adopting the above technical solution, the structural design of the ring and reinforcing ribs enhances the strength and stability of the support frame. The reinforcing ribs are arranged and fixedly connected along the radial direction of the ring, enabling the support frame to withstand greater lifting weights while maintaining the compactness and lightness of the structure.
[0010] Optionally, the support rod is connected to a latch, which is fastened to the ring.
[0011] By adopting the above technical solution, the design of the locking buckle allows the support rod to be securely fastened to the ring, and makes the hook easy to install.
[0012] Optionally, the hook is slidably mounted on the ring, and the ring forms a hook sliding area between two adjacent reinforcing ribs.
[0013] By adopting the above technical solution, the hook is slidably installed on the ring, which allows the hook to be flexibly adjusted according to the position of the loading bucket, improving the adaptability and convenience of the tooling. At the same time, the design of the hook sliding area ensures that multiple hooks do not interfere with each other and remain independent.
[0014] Optionally, the support frame is equipped with multiple sets of stabilization components, each corresponding to a hook. Each stabilization component includes a slider, a vertical rod rotatably connected to the slider, and a limiting rod rotatably mounted on the vertical rod. The slider is slidably mounted on the ring, and the support rod is fixedly connected to a connecting rod. The limiting rod and the connecting rod form a connection relationship.
[0015] By adopting the above technical solutions, the design of the stabilization component further enhances stability during hoisting. The combination of the slider, vertical rod, and limit rod allows for the limiting and fixing of the hook, reducing hook swaying or displacement during hoisting and improving the safety and accuracy of the hoisting process.
[0016] Optionally, a screw is threaded onto the slider, and the end of the screw contacts the annulus.
[0017] By adopting the above technical solution, the screw design allows the slider to be firmly fixed at any position on the ring, further enhancing the stability and reliability of the stabilization component. By adjusting the screw tightening, the slider position can be fine-tuned, improving the tooling's flexibility and adaptability.
[0018] Optionally, the support frame includes a mounting plate, which is fixedly mounted on the reinforcing rib. An adjusting rod is rotatably mounted on the mounting plate, the length of which extends along the radial direction of the ring, and the adjusting rod is connected to the slider.
[0019] By adopting the above technical solution, the design of the mounting plate and adjusting rod enables the slider to move and adjust along the circumferential direction of the ring.
[0020] Optionally, the hook can be detachably mounted on the adjusting rod.
[0021] By adopting the above technical solution, it is easier to select the appropriate number of hooks and the hook installation position according to the hoisting requirements, thereby improving the versatility and practicality of the tooling.
[0022] In summary, this application includes at least one of the following beneficial effects:
[0023] 1. By adopting a structural design with rings and reinforcing ribs, locking and fixing, sliding installation of hooks, and the combined use of stabilizing components, the strength and stability of the lifting equipment are enhanced, preventing the hooks from falling off or swaying, and improving the safety and accuracy of lifting.
[0024] 2. By designing detachable support rods, sliding hooks, and the coordinated use of adjusting rods and sliders, the tooling can adjust the number, position, and angle of hooks according to actual needs, meeting different lifting requirements and improving the flexibility and adaptability of the tooling.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a hoisting fixture. (Refer to...) Figure 1A hoisting fixture includes a support frame 10 and hooks 20 mounted on the support frame 10. There are at least three hooks 20, and in this embodiment of the application, there are four hooks 20. Each hook 20 includes a support rod 21 and an insert rod 22 integrally formed with the support rod 21. The hook 20 is used to connect to a loading bucket 30.
[0031] Reference Figure 2 The filling barrel 30 has insertion holes for inserting the insertion rod 22. The insertion holes are arranged in four vertical rows along the periphery of the filling barrel 30. The same insertion rod 22 can be inserted into different insertion holes in the same vertical row.
[0032] Reference Figure 1 The support frame 10 includes a ring 11 and multiple reinforcing ribs 12 fixedly installed on the ring 11. The reinforcing ribs 12 are arranged radially along the ring 11, and the multiple reinforcing ribs 12 are fixedly connected together by mounting plates 13. The installation of the reinforcing ribs 12 provides support for the ring 11, keeping the ring 11 in place. The support frame 10 also includes multiple diagonal support rods 14. One end of the diagonal support rod 14 is fixedly connected to the ring 11, and the diagonal support rod 14 and the reinforcing ribs 12 form a fixed connection relationship. The other end of the diagonal support rod 14 is inclined upward and connected to a connecting ring 15. Multiple diagonal support rods 14 are connected to the same connecting ring 15. A lifting ring 16 is fixedly connected to the connecting ring 15. When the product is placed into the loading tank 30, a hook 20 is attached to the loading tank 30. The hooks connected to the gantry crane in the factory are connected to the lifting ring 16.
[0033] The support rod 21 is connected to a latch 23, which is prior art and will not be described in detail in this application. The latch 23 is hooked onto the ring 11, so that the hook 20 can be slidably installed on the ring 11. The ring 11 forms a sliding area for the hook 20 between two adjacent reinforcing ribs 12, so that multiple hooks 20 do not interfere with each other.
[0034] Furthermore, refer to Figure 3 When the hoisting tool lifts the material bucket 30, in order to further reduce the shaking of the material bucket 30, a stabilizing component 40 is installed on the support frame 10. There are multiple sets of stabilizing components 40, and each stabilizing component 40 corresponds to a hook 20.
[0035] Reference Figure 3Specifically, the stabilization component 40 includes a slider 41, a vertical rod 42 rotatably connected to the slider 41, and a limiting rod 43 rotatably mounted on the vertical rod 42. The slider 41 is slidably mounted on the ring 11. The rotation center line of the vertical rod 42 and the rotation center line of the limiting rod 43 are perpendicular to each other, and the rotation center line of the vertical rod 42 is coaxial with the central axis of the vertical rod 42. The vertical rod 42 is rotatably mounted on the slider 41 via a bearing. The slider 41 has an arc groove, allowing it to slide along the circumference of the ring 11. As the slider 41 slides on the ring 11, the vertical rod 42 approaches the support rod 21. Both the vertical rod 42 and the support rod 21 are vertical and parallel to each other when stationary. A connecting rod 50 is fixedly connected to the outer wall of the support rod 21. The limiting rod 43 has a slot. Rotating the limiting rod 43 causes it to engage with the connecting rod 50, which is located within the slot. The vertical rod 42 provides constraint on the support rod 21.
[0036] To prevent the slider 41 from sliding easily, a screw 45 is threaded onto the slider 41, and the end of the screw 45 contacts the ring 11. When the screw 45 is pressed against the ring 11, the friction between the slider 41 and the ring 11 increases.
[0037] Furthermore, refer to Figure 3 The mounting plate 13 has an annular groove, the central axis of which is coaxial with the circular ring 11. An adjusting rod 17 is rotatably mounted on the mounting plate 13. One end of the adjusting rod 17 is rotatably mounted on a rotating shaft, and the adjusting rod 17 corresponds one-to-one with the slider 41. The other end of the adjusting rod 17 is connected to a connecting block 18, which is slidably mounted in a groove.
[0038] Rotating the adjusting rod 17 drives the slider 41 to slide, facilitating its movement on the ring 11. If the outer diameter of the filling hopper 30 is too small, the hooks 20 can also be attached to the adjusting rod 17. Only a portion of the hooks 20 need to be attached to the adjusting rod 17 to change the distance between multiple hooks 20. If the hooks 20 are attached to the adjusting rod 17, and the support rod 21 is not far from the vertical rod 42, rotating the vertical rod 42 causes the limiting rod 43 to continue engaging with the corresponding connecting rod, ensuring that the stabilizing component 40 continues to stabilize the support rod 21.
[0039] The implementation principle of a hoisting tool in this application embodiment is as follows:
[0040] Select the appropriate number and type of hooks 20 according to the hoisting requirements, and install them on the support frame 10. Adjust the position of the hooks 20 so that the insertion rod 22 is inserted into the loading barrel 30. Slide the slider 41 to bring the vertical rod 42 closer to the support rod 21. Rotate the limiting rod 43 so that the slot of the limiting rod 43 and the connecting rod 50 are engaged. The stabilizing component 40 plays a limiting role for the hooks 20, which reduces the swaying of the hooks 20 during the subsequent hoisting of the loading barrel 30, so that the loading barrel 30 is not easily deformed and is in a stable moving state during hoisting.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
