TECHNICAL FIELD
[0001] The utility model relates to the technology field of ship unloaders, in particular to a gallery closing system for a ship unloader. BACKGROUND
[0002] At present, the ship unloading operation of large-scale specialized bulk cargo wharfs (mainly coal and iron ore) at home and abroad mainly adopts a bridge type grab ship unloader. When the ship unloading operation is carried out, the grab bucket picks up the material from the ship cabin, and then the material is unloaded into the hopper of the ship unloader. Then, the bulk cargo is transferred to the wharf belt conveyor through the vibrating feeder, and then the bulk cargo is conveyed to the rear stockyard through the belt conveyor.
[0003] The wharf belt conveyor is arranged in an open mode. In order to prevent the bulk dust from flying, a high 2.5m wind shield is usually arranged on both sides of the trestle to suppress dust. However, due to the randomness of wind blowing, there is a phenomenon that the bulk dust flies everywhere during the ship unloading operation. Not only does it pollute the air, but also a lot of dust accumulates on the trestle surface, which needs to be regularly flushed and cleaned, thereby increasing the management cost of the wharf. SUMMARY
[0004] The problem solved by the utility model is how to effectively reduce the flying of bulk dust during the ship unloading operation, so as to reduce air pollution, reduce the accumulation of dust on the trestle, reduce the management cost, and improve the operation efficiency and safety.
[0005] In order to solve the above problems, the utility model provides a gallery closing system for a ship unloader, which comprises a feeding belt conveyor and a wharf belt conveyor. One end of the feeding belt conveyor is provided with a first material chute pipe. One end of the first material chute pipe is connected below a vibrating feeder. The other end of the feeding belt conveyor extends into a transfer hopper. The bottom of the transfer hopper is provided with a second material chute pipe. The second material chute pipe is connected to the upper end of the wharf belt conveyor. First side plates are connected to both sides of the rack of the feeding belt conveyor through support legs. The first side plates extend along the feeding direction of the feeding belt conveyor. One end of the first side plate is connected to the side wall of the first material chute pipe. The other end of the first side plate is connected to the side wall of the transfer hopper. First covering belts are laid on the top of the first side plates on both sides of the feeding belt conveyor. Second side plates are arranged on both sides of the rack of the wharf belt conveyor. The second side plates extend along the feeding direction of the wharf belt conveyor. A support frame is arranged above the transfer hopper. The support frame is connected to the top of the second side plates on both sides of the wharf belt conveyor. Second covering belts are laid on the wharf belt conveyor in the length direction. The second covering belts are arranged above the support frame and the second side plates.
[0006] Optionally, a first anti-overflow apron is connected between the first side plate and the frame of the feeding belt conveyor, and is used for sealing between the first side plate and the frame of the feeding belt conveyor.
[0007] Optionally, the first covering belts at both ends of the first side plate are connected with the side walls of the first material chute and the side walls of the transfer hopper respectively.
[0008] Optionally, the support frame is provided with a first redirection roller and a second redirection roller at both ends along the length direction of the wharf belt conveyor, each of the second side plates is provided with a third redirection roller at one end along the length direction of the wharf belt conveyor, and each of the second side plates is provided with a fourth redirection roller at the other end along the length direction of the wharf belt conveyor, the first redirection roller and the second redirection roller are on the same horizontal plane, the third redirection roller and the fourth redirection roller are on the same horizontal plane, and the second covering belts pass through the third redirection roller, the first redirection roller, the second redirection roller and the fourth redirection roller in sequence.
[0009] Optionally, a second anti-overflow apron is connected between the second side plate and the frame of the wharf belt conveyor, and is used for sealing between the second side plate and the frame of the wharf belt conveyor.
[0010] Optionally, a buffer layer is laid along the length direction of the upper end of the feeding belt conveyor and the wharf belt conveyor.
[0011] Optionally, a plurality of idlers are arranged at intervals along the length direction of the first side plate or the second side plate, and the idlers are used for supporting the covering belts.
[0012] Optionally, a friction-reducing bearing is arranged in the idler.
[0013] Optionally, a deviation rectifying device is arranged on the first side plate and the second side plate.
[0014] Optionally, a safety protection device is arranged on the first side plate and the second side plate.
[0015] The beneficial effect of the corridor sealing system for the ship unloader is that: in the ship unloading operation, bulk cargo (such as coal, iron ore, etc.) is first grabbed from the ship cabin by the bridge grab bucket and unloaded into the hopper of the ship unloader. The vibrating feeder receives the bulk cargo from the hopper and transfers it to the first material chute pipe connected below. The bulk cargo falls into the feeding belt conveyor through the first material chute pipe. The feeding belt conveyor starts to work and conveys the bulk cargo along its feeding direction. In the conveying process of the feeding belt conveyor, the first side plate on both sides plays a guiding and sealing role to prevent the bulk cargo from overflowing from both sides. At the same time, the first covering belt is laid on the top of the first side plate, which further enhances the sealing effect and reduces the flying dust. The bulk cargo is sent into the transfer hopper at the end of the feeding belt conveyor, and then falls into the wharf belt conveyor through the second material chute pipe below. The wharf belt conveyor continues to convey the bulk cargo along its feeding direction to the rear stockyard. In the conveying process of the wharf belt conveyor, the second side plate on both sides plays the same guiding and sealing role, and the second covering belt laid on the support frame further enhances the sealing effect.
[0016] The corridor sealing system for the ship unloader forms a relatively closed corridor system through the side plates on both sides of the feeding belt conveyor and the wharf belt conveyor and the covering belt on the top, effectively reducing the dust flying in the conveying process of the bulk cargo, thereby reducing the air pollution. Due to the reduction of dust, the amount of dust accumulated on the trestle floor will also be reduced accordingly, thereby reducing the frequency of regular flushing and cleaning and reducing the management cost of the wharf. The closed corridor system can reduce the loss and flying of the bulk cargo, so that the bulk cargo can be more efficiently conveyed to the rear stockyard, thereby improving the overall efficiency of the ship unloading operation. The closed corridor system can also reduce the direct contact of workers with the bulk cargo, reduce the probability of work accidents, and enhance the safety of the operation.

[0024] As Figure 1 , Figure 2As shown in the figure, an embodiment of the present invention provides a corridor enclosure system for a ship unloader, comprising: a feeding belt conveyor 1 and a dock conveyor 2. A first material chute 3 is provided on the upper side of one end of the feeding belt conveyor 1, one end of which is connected to the lower part of a vibrating feeder 4. The other end of the feeding belt conveyor 1 extends into a transfer hopper 5. A second material chute 6 is provided at the bottom of the transfer hopper 5 and is connected to the upper end of the dock conveyor 2. First side plates 7 are connected to both sides of the frame of the feeding belt conveyor 1 via support legs. The first side plates 7 extend along the feeding direction of the feeding belt conveyor 1, and one end of the first side plate 7 is connected to the first... The side wall of the material chute 3 is connected, and the other end of the first side plate 7 is connected to the side wall of the transfer hopper 5. A first covering belt 8 is laid between the tops of the first side plates 7 on both sides of the feeding belt 1. A second side plate 9 is provided on both sides of the frame of the dock belt 2. The second side plate 9 extends along the feeding direction of the dock belt 2. A support frame 10 is provided above the transfer hopper 5. The two sides of the support frame 10 are respectively connected to the tops of the second side plates 9 on both sides of the dock belt 2. A second covering belt 11 extending along its length is laid above the dock belt 2. The second covering belt 11 is set above the support frame 10 and the second side plate 9.
[0025] Specifically, the first material chute 3 is arranged on the upper side of one end of the feeding belt conveyor 1, one end of the first material chute 3 is connected with the lower side of the vibrating feeder 4, and the first material chute 3 is used to receive the material falling from the vibrating feeder 4 and guide the material to the feeding belt conveyor 1; the other end of the feeding belt conveyor 1 extends into the transfer hopper 5, so as to convey the material to the transfer hopper 5; the bottom of the transfer hopper 5 is provided with the second material chute 6, the second material chute 6 is connected with the upper end of the wharf belt conveyor 2, and the second material chute 6 is used to guide the material from the transfer hopper 5 to the wharf belt conveyor 2; the first side plate 7 is connected to the both sides of the rack of the feeding belt conveyor 1 through the support leg, the first side plate 7 extends along the feeding direction of the feeding belt conveyor 1, and the first side plate 7 is connected with the side wall of the first material chute 3 and the transfer hopper 5, so as to form a transfer channel; the first covering belt 8 is arranged between the top of the first side plate 7 on the both sides of the feeding belt conveyor 1, so as to enhance the sealing property of the transfer channel; the second side plate 9 is arranged on the both sides of the rack of the wharf belt conveyor 2, and the second side plate 9 also extends along the feeding direction of the wharf belt conveyor 2; the support frame 10 is arranged above the transfer hopper 5, and the both sides of the support frame 10 are connected with the top of the second side plate 9 on the both sides of the wharf belt conveyor 2; the second covering belt 11 is arranged above the support frame 10 and the second side plate 9 along the length direction of the wharf belt conveyor 2, so as to ensure the sealing property of the wharf belt conveyor 2 when conveying the material. In the unloading operation, the grab bucket unloads the material in the funnel of the ship unloader after grabbing the material from the ship cabin, and then the material falls to the first material chute 3 through the vibrating feeder 4. The first material chute 3 guides the material to the feeding belt conveyor 1, and the feeding belt conveyor 1 conveys the material to the transfer hopper 5. The transfer hopper 5 further guides the material to the wharf belt conveyor 2 through the second material chute 6 at the bottom of the transfer hopper 5, and finally the wharf belt conveyor 2 conveys the material to the rear stockyard. The first side plate 7 is connected to the both sides of the rack of the feeding belt conveyor 1 through the support leg, the first side plate 7 extends along the feeding direction of the feeding belt conveyor 1, and the first side plate 7 is connected with the side wall of the first material chute 3 and the transfer hopper 5, in addition, the first covering belt 8 is arranged between the top of the first side plate 7 on the both sides of the feeding belt conveyor 1, so as to form a closed transfer channel, which effectively prevents the dust generated in the transfer process of the material from flying. The second side plate 9 is arranged on the both sides of the rack of the wharf belt conveyor 2, and the second side plate 9 also extends along the feeding direction of the wharf belt conveyor 2. The support frame 10 is arranged above the transfer hopper 5, and the both sides of the support frame 10 are connected with the top of the second side plate 9 on the both sides of the wharf belt conveyor 2. The second covering belt 11 is arranged between the support frame 10 and the second side plate 9, so as to further ensure the sealing property of the wharf belt conveyor 2 when conveying the material.
[0026] In this embodiment, the full-closed design of the feeding belt conveyor 1 and the wharf belt conveyor 2 effectively suppresses the flying of the bulk dust, thereby significantly reducing air pollution and improving the wharf operation environment. Since the flying of the dust is effectively controlled, the trestle floor will not accumulate a large amount of dust, thereby reducing the need for regular flushing and cleaning and reducing the management cost of the wharf. The closed system reduces equipment failures and downtime caused by dust flying, thereby improving the overall efficiency of the unloading operation. The closed system also reduces health problems caused by workers' exposure to dust and improves the safety of the operation process.
[0027] Optionally, a first anti-overflow apron is connected between the first side plate 7 and the rack of the feeding belt conveyor 1, and the first anti-overflow apron is used for sealing between the first side plate 7 and the rack of the feeding belt conveyor 1.
[0028] Specifically, the first anti-overflow apron is made of soft and wear-resistant materials, such as rubber or special synthetic materials, which have good elasticity and sealing performance and can tightly fit between the rack of the feeding belt conveyor 1 and the first side plate 7 to form an effective sealing barrier. The first anti-overflow apron is installed between the rack of the feeding belt conveyor 1 and the first side plate 7 through appropriate connecting members or fixing devices, ensuring that it can maintain a stable position during the operation of the feeding belt conveyor 1 and will not loosen or fall off due to the impact of the material. The design of the first anti-overflow apron makes it difficult for the material to overflow from the gap between the rack and the side plate even if a large impact force is generated during the operation of the feeding belt conveyor 1, thereby effectively preventing the leakage and flying of the dust.
[0029] In this optional embodiment, the first anti-overflow apron significantly improves the sealing performance of the feeding belt conveyor 1 area and effectively prevents the material from overflowing from the gap between the rack and the side plate, thereby reducing the leakage and flying of the dust. Since the material is effectively sealed within the feeding belt conveyor 1, the pollution of the surrounding environment by the dust is reduced, and the wharf operation environment is improved. Since the leakage and flying of the dust are controlled, the trestle floor will not accumulate a large amount of dust, thereby reducing the need for regular flushing and cleaning and reducing the management and maintenance cost of the wharf. The first anti-overflow apron can also effectively prevent the direct impact and wear of the material on the rack and the side plate, thereby prolonging the service life of the equipment.
[0030] Optionally, the first covering belt 8 at both ends of the first side plate 7 is connected with the side wall of the first material chute 3 and the side wall of the transfer hopper 5, respectively.
[0031] Specifically, both ends of the first covering belt 8 are connected to the side walls of the first chute 3 and the transfer hopper 5 via appropriate connectors or fixing devices. These connectors or fixing devices are typically made of high-strength, corrosion-resistant materials to ensure the stability and durability of the connection. The first covering belt 8 is made of high-strength, wear-resistant, and corrosion-resistant materials, such as special synthetic fibers or metal mesh belts. These materials have good toughness and durability, and can withstand the impact and wear during material transfer. Through a carefully designed connection structure and high-quality material selection, the first covering belt 8 can fit tightly against the side plate 7, the side walls of the first chute 3, and the side walls of the transfer hopper 5, forming a continuous and closed transfer channel. This design not only effectively prevents the leakage of materials and dust, but also improves the overall performance and reliability of the corridor enclosure system.
[0032] In this optional embodiment, by connecting the two ends of the first covering belt 8 to the side walls of the first chute 3 and the transfer hopper 5 respectively, a continuous and closed transfer channel is formed. This significantly enhances the sealing performance of the corridor enclosure system, effectively preventing leakage of materials and dust during the transfer process of the feeding belt conveyor 1, thereby reducing dust pollution to the surrounding environment. Since materials and dust are effectively contained within the transfer channel, equipment failures and downtime caused by dust leakage are reduced, improving the overall efficiency of unloading operations. Because dust leakage is controlled, large amounts of dust do not accumulate on the trestle surface and other equipment components, thus reducing the need for regular washing and cleaning, and lowering the management and maintenance costs of the dock.
[0033] Optionally, such as Figure 2 As shown, the support frame 10 is provided with a first redirecting roller 12 and a second redirecting roller 13 at both ends along the length of the dock conveyor belt 2. The two second side plates 9 are each provided with a third redirecting roller 14 at one end of the support frame 10 along the length of the dock conveyor belt 2, and the two second side plates 9 are each provided with a fourth redirecting roller 15 at the other end of the support frame 10 along the length of the dock conveyor belt 2. The first redirecting roller 12 and the second redirecting roller 13 are on the same horizontal plane, and the third redirecting roller 14 and the fourth redirecting roller 15 are on the same horizontal plane. The second cover belt 11 passes through the third redirecting roller 14, the first redirecting roller 12, the second redirecting roller 13, and the fourth redirecting roller 15 in sequence.
[0034] Specifically, the second cover belt 11 extends and is laid along the length of the dock conveyor belt 2. The first redirecting roller 12 and the second redirecting roller 13 are arranged at both ends of the support frame 10 along the length of the second cover belt 11 to ensure that the second cover belt 11 can smoothly bypass them and be laid along a predetermined path. Similarly, the third redirecting roller 14 and the fourth redirecting roller 15 are arranged on the second side plates 9 at both ends of the support frame 10 along the length of the second cover belt 11.
[0035] Because the height of the support frame 10 is higher than the second side plate 9, when the second covering belt 11 is laid along the length extension direction of the wharf belt conveyor 1, it needs to pass through the support frame 10 and cover the second side plate 9 at both ends of the support frame 10 along the length direction of the second covering belt 11, so that when the second covering belt 11 is laid along the length extension direction of the wharf belt conveyor 1, a height difference will be generated between the support frame 10 and the second side plate 9, which will cause a larger tension and fatigue damage to the second covering belt 11. Because the first redirection roller 12 and the second redirection roller 13 are located on the same horizontal plane and on the support frame 10, it can ensure that the second covering belt 11 can smoothly pass through the support frame 10; the third redirection roller 14 and the fourth redirection roller 15 are located on the same horizontal plane and on the second side plate 9 at both ends of the support frame 10 along the length direction of the second covering belt 11, which play a role of transition and guidance to the second covering belt 11, so that the second covering belt 11 can smoothly transition from a low place (the second side plate 9 on both sides of the wharf belt conveyor) to a high place (the support frame), and then smoothly return to a low place (the second side plate 9 on the other side of the support frame along the length direction of the wharf belt conveyor), through the smooth process of the redirection rollers, the tension caused by the height difference is effectively reduced, thereby reducing the fatigue damage to the second covering belt and prolonging its service life. The second covering belt 11 starts from the third redirection roller 14 on one side of the support frame 10, passes through the first redirection roller 12 and the second redirection roller 13 on the support frame 10, and then reaches the fourth redirection roller 15 on the other side of the support frame 10, forming a closed circulation path, in which the redirection rollers play a role of changing the running direction of the second covering belt 11 and providing the necessary tension.
[0036] In this optional embodiment, by reasonably arranging the positions and numbers of the redirection rollers and ensuring that they are on the same horizontal plane, the second covering belt 11 can be smoothly and continuously laid, the tension caused by the height difference is effectively reduced, thereby reducing the fatigue damage to the second covering belt, and the service life of the second covering belt 11 can be significantly prolonged.
[0037] Optionally, the second side plate 9 is connected with the rack of the wharf belt conveyor 2 through a second anti-overflow apron, which is used for sealing between the second side plate 9 and the rack of the wharf belt conveyor 2.
[0038] Specifically, the second anti-overflow skirt is installed between the second side plate 9 and the frame of the wharf belt conveyor 2, forming a tight contact surface that effectively prevents material and dust from overflowing from the tiny gap between the second side plate 9 and the frame. The second anti-overflow skirt is typically made of soft and wear-resistant materials, such as rubber or special synthetic materials, which have good elasticity and sealing performance. When the wharf belt conveyor 2 is in operation, even if the material tries to overflow from the gap between the frame and the side plate, it will be effectively blocked by the second anti-overflow skirt.
[0039] In this optional embodiment, the second anti-overflow skirt significantly improves the sealing performance of the wharf belt conveyor 2 area, effectively preventing material and dust from overflowing from the gap between the frame and the side plate, reducing environmental pollution. Since the material and dust are effectively sealed within the wharf belt conveyor 2, the wharf operating environment is improved, and the harm of dust to workers is reduced. The second anti-overflow skirt can also effectively prevent the direct impact and wear of the material on the frame and side plate, thereby prolonging the service life of the equipment. Since dust leakage is controlled, equipment failures and downtime caused by dust accumulation are reduced, thus reducing the maintenance cost of the wharf.
[0040] Optionally, a buffer layer is laid along the length direction of the upper end of the feeding belt conveyor 1 and the wharf belt conveyor 2.
[0041] Specifically, the buffer layer is laid at the upper end of the feeding belt conveyor 1 and the wharf belt conveyor 2, extending along the length direction and tightly connected to both sides of the frame of the feeding belt conveyor 1 or both sides of the frame of the wharf belt conveyor 2. The buffer layer is typically made of soft and elastic materials, such as rubber, polyurethane, or other high-molecular materials. When the material falls on the belt conveyor, the buffer layer can absorb and disperse the impact energy, reducing the direct impact and wear of the material on the belt conveyor and the corridor side plate. At the same time, the connection of the buffer layer to both sides of the frame also plays a role in fixation and support, enhancing the stability of the belt conveyor during operation.
[0042] In this optional embodiment, the laying and connection of the buffer layer enhance the stability of the belt conveyor during operation, reducing the vibration and shaking caused by material impact. The buffer layer can absorb and disperse the impact energy of the material on the belt conveyor and the corridor side plate, thereby reducing wear and damage and prolonging the service life of the equipment. The buffer layer reduces the noise and vibration caused by material impact, improving the wharf operating environment and enhancing the comfort of workers. Since the stability and durability of the belt conveyor and the corridor side plate are improved, downtime caused by equipment failure is reduced, thereby improving the unloading efficiency.
[0043] Optionally, a plurality of idlers are spaced along the length extension direction of the first side plate 7 or the second side plate 9, and the idlers are used to support the cover belt.
[0044] Specifically, the idler rollers are mounted on the first side plate 7 or the second side plate 9 and are arranged in intervals along the length extension direction of the side plate. The rollers are usually composed of rolling bearings and support structures, which can flexibly support and drive the cover belt. When the cover belt runs in the corridor, the idler rollers play a supporting role to ensure that the cover belt remains in a relatively stable horizontal position.
[0045] In this optional embodiment, the supporting role of the idler rollers can ensure the stability of the cover belt when it runs in the corridor, reducing the sagging or deviation phenomenon, thereby improving the overall stability of the corridor sealing system. The rolling characteristics of the idler rollers reduce the direct contact and friction between the cover belt and the side plate, thereby reducing the wear rate of the cover belt and prolonging the service life. Since the idler rollers can reduce the frictional resistance between the cover belt and the side plate, the energy consumption of the corridor sealing system during operation can be reduced. The supporting and rolling effects of the idler rollers enable the cover belt to run more smoothly in the corridor, reducing downtime and maintenance costs caused by sagging or deviation of the cover belt.
[0046] Optionally, the idler roller is provided with a friction-reducing bearing.
[0047] Specifically, the idler roller, as a key component for supporting the cover belt in the corridor sealing system, plays a crucial role in the internal arrangement of the friction-reducing bearing. The friction-reducing bearing is a component used to reduce friction and wear, which is usually composed of inner ring, outer ring, rolling elements and retainer. In the idler roller, the friction-reducing bearing is installed between the roller shaft and the shaft seat, or more specifically, between the rotating part and the fixed part of the idler roller. When the cover belt runs on the idler roller, it will exert certain pressure and friction on the idler roller. Without the friction-reducing bearing, these forces and frictions will directly act on the shaft and shaft seat of the idler roller, causing severe wear and energy loss. With the friction-reducing bearing, the rolling elements (such as balls or rollers) roll between the inner ring and the outer ring, converting the original sliding friction into rolling friction, thereby greatly reducing the frictional resistance and wear. At the same time, the retainer ensures that the rolling elements roll in the correct position and direction, preventing them from colliding and rubbing against each other.
[0048] In this optional embodiment, the main role of the friction-reducing bearing is to reduce the friction and wear between the idler roller and the cover belt. By replacing sliding friction with rolling friction, energy loss and component wear can be significantly reduced, prolonging the service life of the idler roller and the cover belt. Due to the reduction of frictional resistance, the operation of the idler roller and the cover belt is more smooth, reducing the resistance and energy consumption caused by friction. This helps to improve the operating efficiency of the entire corridor sealing system. The use of friction-reducing bearings reduces the wear of the idler roller and the cover belt, reducing downtime and maintenance costs caused by component damage. The internal arrangement of the friction-reducing bearing in the idler roller enables the idler roller to more stably support the cover belt, reducing vibration and noise caused by friction and wear, and enhancing the stability of the entire corridor sealing system.
[0049] Optionally, the first side plate 7 and the second side plate 9 are each provided with a deviation correction device.
[0050] Specifically, in the gallery closed system, the cover belt as a key component needs to maintain a stable running state to ensure the effective transmission of materials. However, due to various factors (such as wind, uneven distribution of materials, etc.), the cover belt may deviate or run off during operation. In order to correct this deviation and ensure that the cover belt always runs along the predetermined path, a deviation correction device is provided on the first side plate 7 and the second side plate 9. The deviation correction device is usually composed of three parts: a sensor, a controller and an actuator. The sensor is used to monitor the running state of the cover belt in real time, and when the deviation of the cover belt is detected, a signal is transmitted to the controller. The controller analyzes and processes the received signal, calculates the correction amount needed, and issues instructions to the actuator. The actuator adjusts the position or angle of the roller according to the instructions of the controller, or adjusts the tension of the cover belt, etc., to correct the deviation of the cover belt.
[0051] In this optional embodiment, the deviation correction device can monitor and correct the deviation of the cover belt in real time, ensuring that the cover belt always runs along the predetermined path, thereby improving the running stability of the gallery closed system. By correcting the deviation of the cover belt in a timely manner, it can avoid the failure shutdown caused by too large deviation, reduce the downtime and maintenance cost. The use of the deviation correction device reduces the friction and wear between the cover belt and the side plate, prolongs the service life of the cover belt and the side plate. Stable running state of the cover belt helps to ensure the effective transmission of materials, improving the material transmission efficiency.
[0052] Optionally, the first side plate 7 and the second side plate 9 are each provided with a safety protection device.
[0053] Specifically, in the corridor closed system, the safety protection device is a key component to ensure the safe operation of the system. When the corridor closed system is running, the cover belt moves between the first side plate 7 and the second side plate 9 for conveying materials within the corridor. To ensure safety during this process, safety protection devices are installed on both the first side plate 7 and the second side plate 9. The working principle of the safety protection device is usually based on sensor technology and control logic. Sensors are installed at appropriate positions on the first side plate 7 and the second side plate 9 to monitor the operating status of the corridor closed system, including the movement status, position of the cover belt, and possible obstacles, etc. When the sensor detects an abnormal situation, such as the cover belt stopping moving, the position deviating beyond the normal range, or obstacles existing, it will immediately send a signal to the control system. After receiving the signal from the sensor, the control system will immediately analyze and process it. If it confirms that there is a safety hazard, the control system will trigger the safety protection device to take a series of safety measures, such as stopping the movement of the cover belt, sounding an alarm, or starting an emergency shutdown program, to prevent accidents from happening.
[0054] In this optional embodiment, the safety protection device can monitor the operating status of the corridor closed system in real time and take measures immediately when it detects an abnormal situation, effectively preventing accidents from happening and improving the safety of the system. By taking timely measures, the safety protection device can reduce losses such as equipment damage, material loss, and personnel casualties caused by accidents. The presence of the safety protection device enhances the reliability and stability of the corridor closed system, allowing the system to operate safely in various complex environments. In many countries and regions, there are strict regulatory requirements for the safety of industrial equipment and systems. The installation of the safety protection device allows the corridor closed system to meet these regulatory requirements and avoid possible legal risks and fines.
