Description

Technical Field

[0001] This utility model belongs to the field of shot blasting technology, and in particular relates to a shot blasting lifting device for bogies. Background Technology

[0002] In the current field of shot blasting technology, shot blasting is a cold treatment process, which is divided into shot blasting cleaning and shot blasting strengthening. Shot blasting cleaning, as the name suggests, is to remove surface oxide scale and other impurities to improve the appearance quality. Shot blasting strengthening is to use high-speed moving shot to continuously impact the surface of the workpiece to be strengthened. Bogies are one of the most important components in the structure of rail vehicles. During their processing, they need to be shot blasted to strengthen their surface. Therefore, lifting equipment is needed to lift them for shot blasting.

[0003] Utility model patent CN216889704U discloses a lifting device for shot blasting equipment, belonging to the field of lifting technology. It addresses the problems of manual assistance required for loading workpieces before shot blasting, the limitation of hook-type shot blasting machines to blast only one casting at a time, and the inapplicability of single lifting devices to different product types. The device includes a main rod and hooks, with the main rod and hooks fixedly connected. One end of the main rod has a connecting part that mates with the hook, and the other end has the hook. The connecting part is inclined at a certain angle to the main rod and has a through hole that mates with the hook. This utility model achieves automatic coordination between the lifting device and the hook by setting a lifting device with an inclined connecting part; and enables simultaneous shot blasting of multiple parts by setting multiple hooks.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The aforementioned patent achieves automatic coordination between the lifting device and the hook by setting a lifting device with an inclined connecting part. However, when the rotating frame parts need to rotate, the lifting strap needs to be rotated, which can easily cause the lifting strap to become tangled. It is not convenient to adjust the angle of the rotating frame and other parts. At the same time, the use of hooks to hang the rotating frame and other parts is not very secure. When the frame is raised or lowered, the rotating frame and other parts are prone to shaking, resulting in poor safety. Utility Model Content

[0006] This utility model provides a shot blasting lifting device for bogies, aiming to solve the problems mentioned in the background, such as the ease with which lifting straps become entangled when the bogie parts need to rotate, the difficulty in adjusting the angle of the bogie and other parts, the poor stability of using hooks to hang the bogie and other parts, and the easy shaking of the bogie and other parts during lifting, resulting in poor safety.

[0043] Please see Figure 1-5This utility model provides a technical solution: a shot blasting lifting device for a bogie, including a base 1 and a rotating mechanism 2, which includes a fixed seat 21. The fixed seat 21 is fixedly installed on the upper surface of the base 1. A turntable 22 is provided inside the fixed seat 21. The turntable 22 is rotatably connected to the fixed seat 21 through a bearing seat 221. An insertion hole 222 is provided on the turntable 22. A pin 25 is inserted into the fixed seat 21. A connecting seat 23 is fixedly installed on the fixed seat 21. A lifting ring 24 is threadedly connected to the connecting seat 23.

[0044] The lifting strap passes through the lifting ring 24, thereby driving the lifting device and the bogie to move longitudinally. The turntable 22 rotates in the fixed base 21, which facilitates the manual rotation of the base 1 and the adjustment of the angle of the base 1. At the same time, the turntable 22 is fixed by inserting the pin 25 into the insertion hole 222.

[0045] Limiting mechanism 3, two limiting mechanisms 3 are fixedly installed on the lower surface of base 1. The limiting mechanism 3 includes a fixing frame 31, which is fixedly installed on the bottom wall of base 1. A fixing rod 311 is fixedly installed on the outer wall of the fixing frame 31. Two fixing chains 32 are rotatably installed on the fixing rod 311. One end of the two fixing chains 32 is rotatably connected to the fixing rod 311, and the other end is fixedly rotatably connected to the connecting shaft 321.

[0046] Two fixed chains 32 are rotatably connected to the fixed frame 31 via a fixed rod 311, and the fixed frame 31 can be made of I-beams, using the two fixed chains 32 to fix the bogie.

[0047] A rotating shaft 33 is rotatably mounted on the side wall of the fixed frame 31. A fixed plate 34 is fixedly mounted on the rotating shaft 33. A pawl 341 that cooperates with the connecting shaft 321 is fixedly mounted on the side wall of the fixed plate 34. A rotating frame 35 is fixedly mounted on the fixed plate 34. A handle 351 is fixedly mounted on the outer wall of the rotating frame 35. A connecting spring 342 is fixedly mounted on the side wall of the fixed plate 34. One end of the connecting spring 342 is fixedly connected to the fixed plate 34, and the other end is fixedly connected to the outer wall of the fixed frame 31.

[0048] Furthermore, after the fixing chain 32 fixes the bogie, the connecting shaft 321 is engaged by the claw 341. The connecting shaft 321 and the fixing chain 32 are fixed to improve the stability of the fixing bogie. By holding the handle 351 and pushing the rotating frame 35, the claw 341 is moved away from the connecting shaft 321, thereby releasing the fixing chain 32 and making it easier to release the bogie. The connecting spring 342 can drive the fixing plate 34 to reset.

[0049] The hanging mechanism 4 is fixedly installed on the lower surface of the base 1. The hanging mechanism 4 is located between the two limiting mechanisms 3. The hanging mechanism 4 includes a sleeve 41, which is fixedly installed on the lower surface of the base 1. A telescopic frame 42 is slidably connected inside the sleeve 41. A locking bolt 411 that abuts against the telescopic frame 42 is threaded on the outer surface of the sleeve 41. Hooks 421 are fixedly installed on both outer walls of the telescopic frame 42.

[0050] Specifically, the telescopic frame 42 slides within the sleeve 41, facilitating the adjustment of the length of the telescopic frame 42. The two hooks 421 are used to support the middle of the bogie, making the bogie more evenly stressed and less prone to loosening. The telescopic frame 42 can be fixed with locking bolts 411, and the height of the hooks 421 can be adjusted, making it suitable for use with different models of bogies.

[0051] The working principle and usage process of this utility model are as follows: Please refer to... Figure 1-5 The lifting strap passes through the lifting ring 24, thereby driving the lifting device and bogie to move longitudinally. The turntable 22 rotates within the fixed base 21, making it easy to manually rotate the base 1 and adjust the angle of the base 1. At the same time, the pin 25 is inserted into the insertion hole 222 to fix the turntable 22. Two fixed chains 32 are rotatably connected to the fixed frame 31 through the fixed rod 311. The bogie is fixed by the two fixed chains 32. After the fixed chains 32 fix the bogie, the connecting shaft 321 is engaged by the claw 341. The connecting shaft 321 and the fixed chains 32 are fixed to improve the stability of the fixed bogie. By holding the handle 351 and pushing the rotating frame 35, the claw 341 is moved away from the connecting shaft 321, thereby releasing the fixed chain 32. The telescopic frame 42 slides within the sleeve 41, making it easy to adjust the length of the telescopic frame 42. The two hooks 421 are used to support the middle of the bogie, making the force on the bogie more even.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
