Description
Technical Field
[0001] This utility model relates to the field of industrial safety protection technology, specifically to a protective device for industrial rotating machinery with an emergency stop function. Background Technology
[0002] Industrial rotating machinery (such as belt conveyors, grinding machines, CNC machine tool spindles, etc.) is the core equipment in manufacturing production. However, its high-speed rotating parts are prone to mechanical injury accidents, posing a serious threat to the personal safety of operators. According to the safety regulations of the industrial and commercial sectors, the exposed rotating parts of equipment that are accessible to the human body must be equipped with reliable protective devices and emergency braking facilities to deal with sudden dangers.
[0003] Existing protective structures, consisting of only a single fence or protective cover, are insufficient in strength. When high-speed rotating parts break off and fly out, they cannot effectively prevent injury to surrounding personnel. Furthermore, the fence or protective cover is a single unit, requiring complete disassembly if either the fence or the protective cover or a single part of the rotating machinery is damaged, thus increasing the workload. In addition, the protective device lacks an emergency stop function, requiring manual searching for an independent emergency stop button in emergencies. The delayed response can easily lead to the escalation of the accident. Moreover, the lack of a status locking mechanism after an emergency stop poses a risk of accidental restart. Therefore, it is necessary to design an industrial rotating machinery protective device with an emergency stop function to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an industrial rotating machinery protection device with an emergency stop function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial rotating machinery protection device with an emergency stop function, comprising a machine side plate and a rotating shaft, a fixed mounting frame fixedly connected to the lower front end of the machine side plate, a mounting guard plate provided at the upper end of the fixed mounting frame, a connecting rod rotatably connected to the right side of the mounting guard plate, the connecting rod being spirally connected to the fixed mounting frame, an elastic telescopic rod fixedly connected to the rear corner of the mounting guard plate, and a buffer guard frame fixedly connected to the rear movable end of the elastic telescopic rod; A rotating shaft is rotatably connected to the left rear end of the mechanical side plate. An electromagnetic brake is provided on the outer front end of the rotating shaft. The electromagnetic brake is fixedly connected to the mechanical side plate. A pull switch is fixedly connected to the middle position on the upper side of the rear end face of the mounting guard plate. A drive turntable is fixedly connected to the front end of the internal shaft of the pull switch. The drive turntable is rotatably connected to the mounting guard plate.
[0006] Preferably, a transparent observation window is fixedly connected to the inner side of the mounting plate.
[0007] Preferably, a protective net is fixedly connected to the inner side of the buffer frame.
[0008] Preferably, a splicing sleeve is fixedly connected to the left end of the mounting plate, and a torsion block is rotatably connected to the upper right end of the mounting plate. The torsion block is fixedly connected to the connecting rod, and a threaded joint is provided at the lower end of the connecting rod.
[0009] Preferably, a rotating component brake pad is fixedly connected to the outer side of the rotating shaft. A positioning hole is provided on the front end face of the rotating component brake pad. A mechanical locking pin is provided in front of the rotating component brake pad. The position and size of the mechanical locking pin correspond to the position and size of the positioning hole. The mechanical locking pin is fixedly connected to the brake block on the inner side of the electromagnetic brake.
[0010] Preferably, a torsion spring is sleeved on the surface of the rotating shaft between the mounting plate and the drive turntable. The outer torsion arm of the torsion spring is fixedly connected to the mounting plate and the drive turntable respectively. A fixing bolt is spirally connected to the right front end of the drive turntable. A synchronous pull rod is rotatably connected to the outside of the fixing bolt. A mushroom-shaped button is fixedly connected to the left front end of the mounting plate. An infrared grating sensor is provided on the upper side of the rear end face of the mounting plate.
[0011] Preferably, a signal transmission module is fixedly connected to the left front end of the mechanical side plate, and the signal transmission module is electrically connected to the electromagnetic brake, the pull switch, the mushroom-shaped button and the infrared grating sensor respectively.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This device can block flying parts through the protective net. When the impact force is large, the buffer frame moves forward and compresses the elastic telescopic rod, thus effectively buffering the flying parts. When installing the protective plate or disassembling the damaged part, the twist block can be rotated to make the connecting rod screwed into the fixed mounting bracket and inserted into the splicing sleeve for quick assembly. Alternatively, the twist block can be rotated in the opposite direction to remove the connecting rod for quick disassembly and replacement of the damaged part.
[0013] 2. This device can achieve linkage emergency stop control through the setting of pull-type switch, mushroom head button and infrared grating sensor. By pulling the synchronous pull rod at a single position, multiple drive turntables can be rotated simultaneously, so that emergency stop can be performed at any position around the mechanical equipment. This makes the electromagnetic brake drive more timely. Furthermore, the mechanical locking pin can be inserted into the positioning hole to avoid the risk of the mechanical equipment restarting unexpectedly. Attached Figure Description

An elastic telescopic rod 5 is fixedly connected to the rear corner of the mounting guard plate 3. A buffer frame 6 is fixedly connected to the rear movable end of the elastic telescopic rod 5. The elastic telescopic rod 5 and the buffer frame 6 can buffer the flying parts. A rotating shaft 7 is rotatably connected to the left rear end of the mechanical side plate 1. An electromagnetic brake 8 is provided on the outer front end of the rotating shaft 7. The electromagnetic brake 8 is fixedly connected to the mechanical side plate 1. A pull switch 9 is fixedly connected to the middle position on the upper side of the rear end face of the mounting guard plate 3. A drive turntable 10 is fixedly connected to the front end of the internal shaft of the pull switch 9. The drive turntable 10 is rotatably connected to the mounting guard plate 3. By rotating the drive turntable 10, the pull switch 9 can be pulled, thereby enabling timely control of the electromagnetic brake 8 to perform emergency stop of the rotating machinery.
[0018] Specifically, a transparent observation window 11 is fixedly connected to the inner side of the mounting plate 3. The transparent observation window 11 allows for safer observation of the mechanical operation.
[0019] Specifically, a protective net 12 is fixedly connected to the inner side of the buffer frame 6. The flying parts will first impact the protective net 12, which has a preliminary protective effect.
[0020] Specifically, a splicing sleeve 13 is fixedly connected to the left end of the mounting guard plate 3, and a torsion block 14 is rotatably connected to the upper right end of the mounting guard plate 3. The torsion block 14 is fixedly connected to the connecting rod 4. The lower end of the connecting rod 4 is provided with a threaded joint. The connection between the connecting rod 4 and the splicing sleeve 13 facilitates convenient and flexible assembly according to the overall length of the industrial rotating machinery.
[0021] Specifically, a rotating component brake pad 15 is fixedly connected to the outer side of the rotating shaft 7. A positioning hole 16 is provided on the front end face of the rotating component brake pad 15. A mechanical lock stop pin 17 is provided in front of the rotating component brake pad 15. The position and size of the mechanical lock stop pin 17 correspond to the position and size of the positioning hole 16. The mechanical lock stop pin 17 is fixedly connected to the brake block inside the electromagnetic brake 8. After emergency stop, the mechanical lock stop pin 17 can be inserted into the positioning hole 16 at the front end of the rotating component brake pad 15 to avoid the risk of accidental restart.
[0022] Specifically, a torsion spring 18 is sleeved on the rotating shaft surface between the mounting plate 3 and the drive turntable 10. The outer torsion arm of the torsion spring 18 is fixedly connected to the mounting plate 3 and the drive turntable 10 respectively. A fixing bolt 19 is spirally connected to the front right side of the drive turntable 10. A synchronous pull rod 20 is rotatably connected to the outside of the fixing bolt 19. After a worker's limbs accidentally enter the industrial rotating machinery, the worker can pull the synchronous pull rod 20 at his / her position, so that the fixing bolt 19 can drive the drive turntable 10 to rotate, and all the drive turntables 10 can rotate at the same time, thereby opening the pull switch 9, so as to carry out timely emergency stop control according to the worker's position. A mushroom head button 21 is fixedly connected to the front left side of the mounting plate 3. An infrared grating sensor 23 is provided on the upper side of the rear end face of the mounting plate 3.

[0023] Specifically, a signal transmission module 22 is fixedly connected to the front left side of the mechanical side plate 1. The signal transmission module 22 is electrically connected to the electromagnetic brake 8, the pull switch 9, the mushroom-shaped button 21 and the infrared grating sensor 23 respectively. The signal transmission module 22 can greatly reduce the emergency stop response time and avoid signal transmission failure.
[0024] Working Principle: This utility model is an industrial rotating machinery protection device with an emergency stop function. When performing external protection treatment on industrial rotating machinery, firstly, the fixed mounting bracket 2, electromagnetic brake 8, and signal transmission module 22 are installed at the required installation position on the machine side plate 1. Then, the mounting guard plate 3 is placed on the upper end of the fixed mounting bracket 2. By rotating the torsion block 14, the connecting rod 4 can be screwed into the fixed mounting bracket 2, thereby realizing the installation of the mounting guard plate 3. The connecting rod 4 on the outer side of the adjacent mounting guard plate 3 is first inserted into the left splicing plug of the installed guard plate 3. In set 13, the connecting rod 4 is screwed to the fixed mounting bracket 2, enabling rapid assembly of the mounting plate 3. A pull switch 9 is installed on the upper rear end of each mounting plate 3 and connected to the corresponding drive turntable 10. After installation, if a worker accidentally enters the industrial rotating machinery, they can pull the synchronous pull rod 20 at their location, causing the fixing bolt 19 to rotate the drive turntable 10 simultaneously. This allows the pull switch 9 to open, or... The mushroom-shaped button 21 and the infrared grating sensor 23 enable linkage control processing, making emergency stop response more timely. The switch signal is transmitted to the signal transmission module 22, so that the electromagnetic brake 8 can respond in time and brake the rotating shaft 7 and the rotating component brake pad 15, thereby avoiding the risk of accident expansion due to response delay. The mechanical lock pin 17 can be inserted into the positioning hole 16 at the front end of the rotating component brake pad 15 to avoid the risk of accidental restart. When a part flies out due to an internal fault in the industrial rotating machinery, emergency stop control can also be performed. The flying part will first impact the protective net 12. When the impact force is large, the buffer frame 6 moves forward and the elastic telescopic rod 5 is compressed, thereby effectively buffering the flying part. When disassembling the damaged part of the mounting plate 3, the connecting rod 4 can be removed by rotating the torsion block 14 in the opposite direction, so as to quickly disassemble and replace the damaged part, avoiding the workload of overall disassembly and replacement and reducing the overall replacement cost. The transparent observation window 11 allows for safer observation of the machine operation.
