Abstract
Description
Technical Field
[0001] This invention relates to the field of large casting production and processing technology, and in particular to a suspended crushing device for large casting systems. Background Technology
[0002] In the production and processing of large castings, after the casting system completes the casting operation, it is necessary to remove the scrap material generated around the casting. This step plays a crucial role in ensuring the quality of the finished casting and meeting the needs of subsequent processing. Moreover, if the casting is to be recycled, it must first undergo crushing. However, traditional scrap removal operations mainly rely on manual operation, which brings many technical pain points and challenges to the industry.
[0003] Traditional methods of removing scrap rely on manual labor, requiring tools to pry and knock away the scrap from the casting. This process is cumbersome and time-consuming, making it difficult to meet the needs of assembly line mass production. Furthermore, manual operation makes it difficult to precisely control the force applied, and excessive force can easily cause scratches or damage to the casting itself.
[0004] Large castings often weigh several tons, while traditional edge material crushing equipment has a limited coverage area. To process edge material from different locations on a casting, hoisting equipment is needed to move the casting to the equipment's operating area. This process not only consumes a lot of auxiliary time but also poses safety hazards such as collisions and overturning of the casting during hoisting.
[0005] Furthermore, most suspended or lifting crushing equipment lacks effective emergency protection devices when the lifting drive mechanism malfunctions, making it highly susceptible to rapid equipment falls. Such falls not only damage ground facilities but also pose a serious safety threat to on-site operators, failing to meet the management requirements of "zero safety accidents" in industrial production.
[0006] Therefore, a suspended crushing device for large casting systems is proposed. Summary of the Invention

The other end of the steel wire rope is fixedly connected to a bracket. A wing ring plate is hinged to the bottom end of the bracket. The wing ring plate is rotatably connected to the cylinder.
[0014] Preferably, one end of the second air supply pipe is fixedly connected to one side of the pneumatic lifting rod, and a three-way valve is fixedly connected to the other end of the second air supply pipe.

[0017] Preferably, a first damping spring is provided inside the first telescopic airbag, and a second damping spring is provided inside the second telescopic airbag.
[0018] The beneficial effects of this invention are: 1. This invention designs an edge material crushing mechanism that uses an air pump as a power source. Air is supplied to the cylinder through a first air supply pipe, driving the piston, piston rod, and slider to expand the expansion clamps and separate the edge material. The operation can be completed simply by controlling the air pump control switch. Its function is to replace traditional manual operation, which not only improves the efficiency of edge material removal, but also avoids problems such as scratches and defects on the casting body caused by uneven manual force, thus ensuring the quality of the finished casting. After depressurization, the first and second reset springs automatically drive the components to reset, eliminating the need for manual adjustment. This greatly shortens the edge material processing time for a single batch of castings, significantly improves the continuity of operation, and can meet the needs of assembly line batch operation.
[0019] 2. This invention designs a position control mechanism to match the material crushing mechanism. Through the linkage control of the function control switch, the pneumatic lifting rod can be used to drive the main body of the equipment to lift and lower by switching the three-way valve. The servo motor can be started to complete the horizontal movement. The operation is convenient and does not require complicated debugging. The multi-dimensional adjustment capability expands the coverage area of the main body of the equipment. There is no need to move the castings weighing several tons, saving auxiliary time such as hoisting and relocation. A single machine can be responsible for crushing side materials at multiple stations, thus improving the utilization rate of the equipment.
[0020] 3. This invention, through the design of a reset protection mechanism in conjunction with a position control mechanism, automatically triggers protection in the event of a pneumatic lifting rod malfunction. The equipment body descends slowly through the gas buffering effect of the first telescopic airbag, circulation tube, and second telescopic airbag, requiring no manual intervention. Its function is to construct a safety barrier for the equipment. The slow descent design significantly reduces the falling speed of the equipment body, completely avoiding safety accidents such as damage to ground facilities and personal injury caused by equipment falling, meeting the management requirements for zero safety accidents in industrial production. Furthermore, the damping balance effect of the first and second damping springs maintains the vertical posture of the equipment body after slow descent, preventing secondary damage such as deformation of the expansion clamps and breakage of the wire rope caused by equipment tilting.

[0026] Please see Figures 1 to 7 The present invention provides a technical solution: a suspended crushing device for a large casting system, comprising a main body 1, with a casting 2 placed below the main body 1. The main body 1 includes an edge material crushing mechanism 3, a position control mechanism 4, and a reset and protection mechanism 5. The edge material crushing mechanism 3 is located at the upper and lower ends of the main body 1 and is used to remove the edge material around the casting 2. The position control mechanism 4 is located above the main body 1 and is used to control the movement and lifting of the main body 1. The reset and protection mechanism 5 is located on the position control mechanism 4 and is used to limit the falling speed of the main body 1.
[0027] As one embodiment of the present invention, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the edge material crushing mechanism 3 includes a cylinder 31 located at the upper end of the main body 1. A controller 311 is fixedly installed on the outer side of the cylinder 31. A first handle 32 is fixedly installed at the upper end of the cylinder 31. An air pump control switch 321 is located at the bottom end of the first handle 32. A piston 33 is slidably connected inside the cylinder 31. One end of a piston rod 331 is fixedly connected to the bottom end of the piston 33. The other end of the piston rod 331 passes through the main body 1 and is fixedly connected to a slider 332. A first return spring 34 is sleeved on the outer side of the piston rod 331. The slider 332 is located in a movable cavity 35, which is opened inside the main body 1. The internal sliding connection has two symmetrical sets of expansion clamps 36. Each set of expansion clamps 36 has a reset chamber 361 on its opposite side. The two sets of reset chambers 361 are jointly provided with a second reset spring 37. The two ends of the second reset spring 37 are fixedly connected to the two sets of expansion clamps 36 respectively. A first ball bearing 362 is rotatably connected to the expansion clamps 36. The first ball bearing 362 is rolledly connected to the inner wall of the movable cavity 35. One end of the first air supply pipe 381 is fixedly connected to the upper outer side of the cylinder 31. The other end of the first air supply pipe 381 is fixedly connected to an air pump 38. A pressure relief valve 382 is provided on the side of the air pump 38. A three-way valve 39 is provided on the first air supply pipe 381.
[0028] By adopting the above technical solution, during use, first insert the expansion clamps 36 at the bottom of the main body 1 into the edge material of the casting 2. Then, press the air pump control switch 321 at the bottom of the first handle 32. The air pump control switch 321 controls the air pump 38 to start through the controller 311. The air pump 38 sends gas into the cylinder 31 through the first air supply pipe 381. Then, the gas in the cylinder 31 drives the slider 332 to descend through the cylinder 31 and the piston rod 331, causing the slider 332 to drive the two sets of expansion clamps 36 to expand outward, thereby removing the edge material on the outside of the casting 2. Finally, the air pump control switch 321 controls the pressure relief valve 382 to start through the controller 311. The pressure relief valve 382 discharges the gas in the cylinder 31 through the first air supply pipe 381. At this time, the restoring force of the first return spring 34 drives the slider 332 through the piston rod 331 and the piston rod 331 to move the slider 332 to descend. As block 332 rises, the restoring force of the second reset spring 37 can drive the two sets of expansion clamps 36 to reset. This facilitates the use of air pump 38 as a power source to supply air to cylinder 31 through first air supply pipe 381, driving piston 33, piston rod 331 and slider 332 to work together, causing expansion clamps 36 to expand outward to separate the edge material. The operation can be completed by controlling air pump control switch 321. Its function is to replace traditional manual operation, which not only improves the efficiency of edge material removal, but also avoids problems such as scratches and defects on the casting 2 body caused by uneven manual force, ensuring the quality of the finished casting 2. After depressurization, the first reset spring 34 and the second reset spring 37 automatically drive the components to reset without manual adjustment, which greatly shortens the edge material processing time of a single batch of castings, greatly improves the continuity of operation, and can meet the needs of assembly line batch operation.
[0029] As one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 6 As shown, the position control mechanism 4 includes a support platform 41 mounted above the main body 1. A base 42 is mounted on the upper end of the support platform 41. A pneumatic lifting rod 43 is fixedly mounted on the upper end of the base 42. A lifting plate 44 is fixedly connected to the upper end of the pneumatic lifting rod 43. A lifting rod 441 is fixedly connected to the bottom end of the lifting plate 44. The bottom end of the lifting rod 441 passes through a slide rail 411 and is fixedly connected to a base plate 442. A top plate 443 is sleeved on the outer side of the lifting rod 441. One end of a steel wire rope 45 is fixedly mounted on the bottom end of the base plate 442. The other end of the steel wire rope 45 is fixedly connected to a bracket 46. A wing ring plate 461 is hinged to the bottom end of the bracket 46 and is rotatably connected to the cylinder 31. One end of the second air supply pipe 431 is fixedly connected to one side of the pneumatic lifting rod 43, and the other end of the second air supply pipe 431 is fixedly connected to the three-way valve 39. The bottom end of the equipment base 42 and the top end of the top plate 443 are both rotatably connected to the second ball bearing 421. The second ball bearing 421 is slidably connected in the slide rail 412. The slide rail 412 is opened at the upper and lower ends of the support platform 41. The upper end of the equipment base 42 is fixedly installed with a servo motor 47. The output shaft of the servo motor 47 is fixedly connected to a gear 471. The gear 471 meshes with a rack 472. The rack 472 is fixedly installed at the front end of the support platform 41. The front end of the equipment body 1 is fixedly installed with a second handle 48. The second handle 48 is equipped with a function control switch 481.
[0030] By adopting the above technical solution, when it is necessary to raise or lower the position of the main body 1 of the equipment to change the crushing position, firstly press the function control switch 481 at the bottom of the second handle 48. The function control switch 481 controls the three-way valve 39 to switch connections through the controller 311, so that the air pump 38 and the pressure relief valve 382 can supply and exhaust air to the pneumatic lifting rod 43 through the second air supply pipe 431. Then, the pneumatic lifting rod 43 drives the wire rope 45 to rise and fall through the lifting plate 44, the lifting rod 441, and the base plate 442. The wire rope 45 drives the main body 1 of the equipment to rise and fall through the bracket 46 and the wing ring plate 461. Finally, press the function control switch 481. The function control switch 481 controls the servo motor 47 to start through the controller 311. The servo motor 47 drives the gear 471 to rotate because Gear 471 meshes with rack 472, which is fixed on the equipment base 42. Therefore, servo motor 47 can drive equipment base 42 to move on support platform 41, thereby allowing the main body 1 of the equipment to follow the position of equipment base 42. The friction of equipment base 42 during movement is reduced by second ball bearing 421 and slide rail 412, which is conducive to linkage control through function control switch 481. Switching three-way valve 39 can realize the pneumatic lifting rod 43 to drive the main body 1 to lift and lower. Starting servo motor 47 can complete horizontal movement. The operation is convenient and does not require complicated debugging. The multi-dimensional adjustment capability expands the coverage area of the main body 1. There is no need to move the casting 2 weighing several tons, saving auxiliary time such as hoisting and relocation. A single machine can be responsible for crushing edge materials at multiple stations, improving equipment utilization.
[0031] As one embodiment of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the reset protection mechanism 5 includes a first telescopic airbag 51 and a second telescopic airbag 53 sleeved on the outside of the lifting rod 441. The first telescopic airbag 51 is disposed between the equipment base 42 and the lifting plate 44, and the second telescopic airbag 53 is disposed between the bottom plate 442 and the top plate 443. One end of the circulation tube 52 is fixedly connected to the inner side of the first telescopic airbag 51, and the other end of the circulation tube 52 passes through the lifting rod 441 and is fixedly connected to the second telescopic airbag 53. A first damping spring 54 is disposed inside the first telescopic airbag 51, and a second damping spring 55 is disposed inside the second telescopic airbag 53.
[0032] By adopting the above technical solution, when the pneumatic lifting rod 43 malfunctions and loses its function, the main body 1 of the equipment begins to fall under its own weight. At this time, the weight of the main body 1 drives the lifting plate 44 to compress the first telescopic airbag 51 through the lifting rod 441, the base plate 442, the wire rope 45, the bracket 46, and the wing ring plate 461. Because the gas in the first telescopic airbag 51 can only flow into the second telescopic airbag 53 through the circulation pipe 52 with a small flow rate, the main body 1 can only descend slowly, thus achieving a soft landing. Then, because the first telescopic airbag 51 is equipped with a first damping spring 54 and the second telescopic airbag 53 is equipped with a second damping spring 55, the first damping spring 54 and the second damping spring 55 can neutralize the lifting force and maintain balance, allowing the main body of the equipment to fall. 1. Even when the pneumatic lifting rod 43 loses its force, the main body of the equipment 1 can still return to a vertical position, which is conducive to automatically triggering protection when the pneumatic lifting rod 43 fails. The equipment body 1 is slowly lowered through the gas buffering effect of the first telescopic airbag 51, circulation pipe 52 and second telescopic airbag 53 without manual intervention. Its function is to build a safety protection barrier for the equipment. The slow descent design greatly reduces the falling speed of the main body of the equipment 1, completely avoiding safety accidents such as damage to ground facilities and personal injury caused by equipment falling. It meets the management requirements of zero safety accidents in industrial production. In addition, the damping balance effect of the first damping spring 54 and the second damping spring 55 can maintain the vertical posture of the main body of the equipment 1 after slow descent, avoiding secondary damage such as deformation of the expansion clamp 36 and breakage of the wire rope 45 caused by equipment tilting.
[0033] Working principle: When in use, first insert the expansion clamp 36 at the bottom of the main body 1 into the edge material of the casting 2. Then press the air pump control switch 321 at the bottom of the first handle 32. The air pump control switch 321 controls the air pump 38 to start through the controller 311. The air pump 38 sends gas into the cylinder 31 through the first air supply pipe 381. Then the gas in the cylinder 31 drives the slider 332 to descend through the cylinder 31 and the piston rod 331. The slider 332 drives the two sets of expansion clamps 36 to expand outward, thereby removing the edge material on the outside of the casting 2. Finally, the air pump control switch 321 controls the pressure relief valve 382 to start through the controller 311. The pressure relief valve 382 discharges the gas in the cylinder 31 through the first air supply pipe 381. At this time, the restoring force of the first return spring 34 drives the slider 332 to rise through the piston rod 331 and the piston rod 331. This allows the restoring force of the second return spring 37 to drive the two sets of expansion clamps 36 to reset. When it is necessary to raise or lower the main body of the equipment to change the crushing position, first press the function control switch 481 at the bottom of the second handle 48. The function control switch 481 controls the three-way valve 39 to switch connections through the controller 311, so that the air pump 38 and the pressure relief valve 382 can supply and exhaust air to the pneumatic lifting rod 43 through the second air supply pipe 431. Then, the pneumatic lifting rod 43 drives the wire rope 45 to rise and fall through the lifting plate 44, the lifting rod 441, and the base plate 442. The wire rope 45 drives the main body of the equipment through the bracket 46 and the wing ring plate 461. The body 1 is raised and lowered. Finally, the function control switch 481 is pressed. The function control switch 481 controls the servo motor 47 to start through the controller 311. The servo motor 47 drives the gear 471 to rotate. Because the gear 471 meshes with the rack 472, and the rack 472 is fixed on the equipment base 42, the servo motor 47 can drive the equipment base 42 to move on the support platform 41, so that the main body 1 moves with the equipment base 42. The friction of the equipment base 42 when it moves is reduced by the second ball 421 and the slide rail 412. When the pneumatic lifting rod 43 malfunctions and becomes ineffective, the main body 1 of the equipment begins to fall under its own weight. At this time, the weight of the main body 1 drives the lifting plate 44 to compress the first telescopic airbag 51 through the lifting rod 441, the base plate 442, the wire rope 45, the bracket 46, and the wing ring plate 461. Because the gas in the first telescopic airbag 51 can only flow into the second telescopic airbag 53 through the circulation pipe 52 with a small flow rate, the main body 1 can only descend slowly, thus achieving a soft landing. Then, because the first telescopic airbag 51 is equipped with a first damping spring 54 and the second telescopic airbag 53 is equipped with a second damping spring 55, the first damping spring 54 and the second damping spring 55 can neutralize the lifting force and maintain balance, so that the main body 1 can still return to a vertical position when the pneumatic lifting rod 43 loses its force.
