Description

Technical Field

[0001] This invention belongs to the field of conveyor self-protection technology, specifically a novel emergency self-protection device for belt conveyors. Background Technology

[0002] While existing belt conveyor protection and emergency stop devices ensure that on-site personnel can trigger emergency stops nearby through a distributed design on both sides and the control box, their passive response mechanism presents significant safety hazards. When the operating area is unattended, if personnel accidentally or improperly enter the belt conveyor area, the lack of autonomous stopping capability can easily lead to serious accidents such as entanglement or collisions, potentially causing cascading damage to equipment. Such scenarios expose the over-reliance of traditional protection on active human intervention, necessitating the construction of a blind-spot-free automatic emergency stop system by adding intelligent monitoring technologies such as infrared sensing and laser scanning. This would fundamentally shift accident prevention from "human-based" to "technology-based." Summary of the Invention

[0003] The purpose of this invention is to provide a novel emergency personal protection device for belt conveyors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel emergency personal protection device for a belt conveyor, comprising a fixed frame, a protective box fixedly installed on the top of the fixed frame, an internal fixed rod in the protective box, an inlet baffle movably installed on the outer surface of the fixed rod, a sensor fixedly installed on the inner side of the inlet baffle, a limit strip movably installed inside the protective box, an outlet stop plate fixedly installed at the bottom of the limit strip, a conveying mechanism provided inside the fixed frame, and an emergency handle fixedly installed on the top of the protective box.

[0005] Preferably, the limiting strip has a positioning hole inside, a positioning block is movably installed inside the positioning hole, a box body is fixedly installed on the left side of the protective box, a pull rod is fixedly installed at one end of the positioning block, and one end of the pull rod passes through the box body, and a spring is fixedly installed between the positioning block and the box body.

[0006] Preferably, a fixed shaft is movably installed inside the fixed frame, with both ends of the fixed shaft passing through the interior of the fixed frame. A driven gear is fixedly installed at one end of the fixed shaft, and a fixed frame is fixedly installed at one end of the driven gear and the other end of the fixed shaft. A roller is installed on the outer surface of one end of the fixed frame. A drive gear is movably installed on the front of the fixed frame, and the drive gear and the driven gear are meshed. A fixed disk is fixedly installed on the front of the driven gear, and a rotating handle is fixedly installed on the outer surface of the fixed disk.

[0007] Preferably, the conveying mechanism is disposed inside the fixed frame. The conveying mechanism includes a first rotating shaft movably installed inside the fixed frame, with both ends of the first rotating shaft penetrating the interior of the fixed frame. A drive wheel is fixedly installed at one end of the first rotating shaft. A motor is fixedly installed on the front of the fixed frame. A motor is fixedly installed at the output end of the motor, with one end of the motor penetrating the interior of the fixed frame. A driven wheel is fixedly installed at one end of the motor. A transmission belt drives through the driven wheel and the drive wheel. A conveyor belt drives through the outer surfaces of the first rotating shaft, the second rotating shaft, and the roller.

[0008] Preferably, a support plate is fixedly installed at the bottom of the fixed frame, and a fixed plate is fixedly installed between the two support plates.

[0009] Preferably, a reinforcing rib is fixedly installed between the support plate and the fixing plate, and the reinforcing rib is triangular in shape.

[0010] Preferably, a fixing seat is fixedly installed on the front of the support plate, a fixing block is movably installed inside the fixing seat, and a toolbox is fixedly installed on the front of the fixing block.

[0011] Preferably, a support base is fixedly installed on the front of the fixed frame, and the interior of the support base is in the form of a U-shaped groove.

[0012] Preferably, the emergency handle is U-shaped on the top of the protective box, and the emergency handle is arranged in a linear array.

[0013] Preferably, the outer diameter of the fixing block is equal to the inner diameter of the fixing seat, and the interior of the fixing seat has a smooth surface design.

[0014] The beneficial effects of this invention are as follows: 1. This invention employs a movable inlet baffle linked to sensors at the entrance, which can instantly trigger a stop signal when personnel accidentally enter, with a response sensitivity down to the millisecond level. If the main detection system fails, the emergency handle on the top of the protective box provides physical braking, mechanically locking personnel to prevent them from moving with the conveyor belt. The stop at the exit is driven by a limit strip, forming a reliable physical barrier that effectively prevents personnel from being drawn into dangerous areas. These three protective mechanisms work independently yet collaboratively, constructing a complete safety chain from sensing and braking to isolation, shortening equipment failure response time, increasing the success rate of personnel protection, and significantly reducing the risk of industrial accidents.

[0015] 2. Compared with traditional devices, this invention achieves efficient and safe protection through the precise coordination of multiple structures via the installation of the outlet stop plate: the pull rod and the positioning block form a rigid transmission chain to ensure accurate transmission of operating force; the conical tail of the positioning block and the spring constitute an elastic energy storage system to achieve rapid avoidance and reset; the box guide rail and the positioning block cooperate to ensure displacement accuracy; the serrated structure of the limit strip and the wedge-shaped surface of the positioning block form a mechanical interlock, which, together with the circular groove of the fixed plate, constitutes a three-level positioning safety; this mechanism uses the instantaneous release technology of spring potential energy to enable the positioning block to complete self-locking, while realizing quick installation by a single person, significantly improving equipment maintenance efficiency and personnel safety.

[0016] 3. Compared with traditional devices, this invention achieves efficient and precise control through the cooperation between the roller and the fixed frame. Operators can easily drive the entire transmission by simply rotating the handle. The mechanism employs a wedge-shaped compression mechanism and a vertical displacement design of the support plate, enabling fine adjustment of belt tension and ensuring extremely high precision in tension control. Simultaneously, the application of double-gear backlash elimination technology effectively eliminates transmission backlash, avoiding overshoot during adjustment and making the adjustment smoother and more reliable. The self-lubricating and wear-resistant coating on the support plate surface significantly reduces belt friction loss while achieving controllable pressure application. The entire mechanism achieves dynamic balance of belt tension through precise mechanical linkage, extending the service life of the conveyor belt and supporting real-time adjustment under load, thereby significantly improving equipment maintenance efficiency and operational stability.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, this embodiment of the invention provides a novel emergency self-protection device for a belt conveyor, including a fixed frame 1, a protective box 2 fixedly installed on the top of the fixed frame 1, a fixed rod 27 inside the protective box 2, an inlet baffle 20 movably installed on the outer surface of the fixed rod 27, a sensor 32 fixedly installed on the inner side of the inlet baffle 20, a limit strip 28 movably installed inside the protective box 2, an outlet stop plate 26 fixedly installed at the bottom of the limit strip 28, a conveying mechanism inside the fixed frame 1, and an emergency handle 8 fixedly installed on the top of the protective box 2.

[0021] When personnel enter the conveyor entrance, the inlet baffle 20 is pushed to rotate around the fixed rod 27, triggering the inner sensor 32 to send a linkage signal, which immediately cuts off the power to the conveyor mechanism and stops the machine instantly. If the inlet detection system fails, the emergency handle 8 located on the top of the protective box 2 can be manually grabbed by personnel, and the mechanical locking prevents the body from continuing to move with the belt. At the exit, the limit bar 28 drives the exit stop 26 to form a physical barrier to prevent personnel from being transported to the danger zone. The movable inlet baffle at the entrance is linked with the sensor, and when personnel accidentally enter, it can immediately trigger a stop signal with a response sensitivity of up to milliseconds. If the main detection system fails, the emergency handle on the top of the protective box can provide physical braking and prevent personnel from moving with the belt through mechanical locking. The operating force is only 20N to trigger. The stop at the exit is driven by the limit bar to form a reliable physical barrier, effectively preventing personnel from being pulled into the danger zone. The three protection mechanisms are independent of each other and work together to build a complete safety chain from sensing, braking to blocking, which shortens the equipment failure response time, improves the success rate of personnel protection, and significantly reduces the risk of industrial accidents.

[0022] The limiting strip 28 has a positioning hole 34 inside, and a positioning block 29 is movably installed inside the positioning hole 34. The box body 30 is fixedly installed on the left side of the protective box 2. A pull rod 31 is fixedly installed at one end of the positioning block 29, and one end of the pull rod 31 passes through the box body 30. A spring 14 is fixedly installed between the positioning block 29 and the box body 30.

[0023] According to the coal conveying situation, the staff needs to install the outlet stop plate 26. By holding the pull rod 31, the staff can pull the positioning block 29 to one side of the box 30 inside the protective box 2. The positioning block 29 will compress the spring 14 inside the box 30, so that the positioning block 29 passes through the inside of the protective box 2 and enters the inside of the box 30. Now, by holding the outlet stop plate 26, the staff can insert the limiting strip 28 into the inside of the protective box 2. When the limiting strip 28 is fully inside the protective box 2, the staff can release the pull rod 31, so that the spring 14 will compress the positioning block 29 inside the box 30, so that the positioning block 29 will quickly enter the inside of the fixed plate 23. The positioning block 29 will limit the limiting strip 28, thus completing the installation of the outlet stop plate 26.

[0024] The installation of the outlet stop plate 26 requires precise positioning via a mechanical linkage mechanism. The operator first pulls the lever 31 outwards, causing the positioning block 29 to move along a pre-set track within the protective box 2 towards the box body 30. During this process, the conical structure at the tail of the positioning block 29 continuously compresses the spring 14. When the spring compression reaches a critical value, the positioning block 29 completely retracts into the box body 30, creating clearance space. At this point, the limiting strip 28 of the outlet stop plate 26 is vertically inserted into the guide groove of the protective box 2 until the bottom of the limiting strip 28 contacts the surface of the fixed plate 23. After releasing the lever 31, the elastic potential energy stored in the spring 14 is released instantaneously, pushing the positioning block 29 to rebound rapidly. Its front wedge-shaped surface forms a mechanical self-lock with the circular groove of the fixed plate 23, cooperating with the limiting strip 28. The serrated structure on both sides of the device achieves dual limiting. Compared with traditional devices, this device achieves efficient and safe protection through the installation of the outlet stop plate 26 and the precise cooperation of multiple structures: the pull rod 31 and the positioning block 29 form a rigid transmission chain to ensure accurate transmission of operating force; the conical tail of the positioning block 29 and the spring 14 form an elastic energy storage system to achieve rapid avoidance and reset; the guide rail of the box 30 cooperates with the positioning block 29 to ensure displacement accuracy; the serrated structure of the limiting strip 28 and the wedge-shaped surface of the positioning block 29 form a mechanical interlock, which, together with the circular groove of the fixed plate 23, forms a three-level positioning safety; the mechanism uses the instantaneous release technology of spring potential energy to enable the positioning block 29 to complete self-locking, and at the same time achieves quick installation by a single person, significantly improving equipment maintenance efficiency and personnel safety.

[0025] The fixed frame 1 has a fixed shaft 25 installed inside it. The two ends of the fixed shaft 25 pass through the interior of the fixed frame 1. A driven gear 21 is fixedly installed at one end of the fixed shaft 25. A fixed frame 4 is fixedly installed at one end of the driven gear 21 and the other end of the fixed shaft 25. A roller 3 is installed on the outer surface of one end of the fixed frame 4. A drive gear 22 is installed on the front of the fixed frame 1. The drive gear 22 and the driven gear 21 are meshed. A fixed disk 23 is fixedly installed on the front of the driven gear 21. A rotating handle 24 is fixedly installed on the outer surface of the fixed disk 23.

[0026] The operator needs to adjust the tension of the conveyor belt 13 by rotating the handle 24. The handle 24 rotates the fixed plate 23, which in turn rotates the drive gear 22 inside the fixed frame 1. The drive gear 22 meshes with the driven gear 21, which in turn rotates the driven gear 21. The driven gear 21 then rotates the fixed shaft 25 and the handle 24 synchronously. The rollers 3 on the outer surface of the fixed frame 4 press the conveyor belt 13, and the rollers 3 adjust the tension of the conveyor belt 13, thus completing the adjustment of the tension of the transmission belt 15.

[0027] The tension adjustment of the conveyor belt 13 is achieved through precision mechanical transmission: the operator manually rotates the handle 24, driving the fixed plate 23 to rotate synchronously. The fixed plate 23 drives the drive gear 22 to rotate within the fixed frame 1. The drive gear 22 meshes with the driven gear 21, and after the torque is amplified by the gear reduction ratio, the driven gear 21 drives the fixed shaft 25 and the support plate 5 to make precise displacements. The roller 3 moves vertically along the surface of the fixed frame 4, applying controllable pressure to the conveyor belt 13 through the wedge-shaped extrusion mechanism to achieve belt tension adjustment. Compared with traditional devices, this device achieves efficient and precise control through the cooperation between the roller 3 and the fixed frame 4. The operator only needs to manually rotate the handle to easily drive the entire transmission. The mechanism adopts a wedge-shaped extrusion mechanism and a vertical displacement design of the support plate, which can finely adjust the belt tension and ensure that the tension control reaches extremely high precision. Meanwhile, the application of double-gear backlash elimination technology effectively eliminates transmission backlash, avoids overshoot during adjustment, and makes adjustment more stable and reliable; the self-lubricating wear-resistant coating covering the support plate surface not only achieves controllable pressure application but also significantly reduces belt friction loss; the entire mechanism achieves dynamic balance of belt tension through precise mechanical linkage, which not only extends the service life of the conveyor belt but also supports real-time adjustment under load, thereby significantly improving the equipment's maintenance efficiency and operational stability.

[0028] The conveying mechanism is located inside the fixed frame 1. The conveying mechanism includes a first rotating shaft 12 movably installed inside the fixed frame 1, with both ends of the first rotating shaft 12 penetrating through the interior of the fixed frame 1. A drive wheel 16 is fixedly installed at one end of the first rotating shaft 12. A motor 17 is fixedly installed on the front of the fixed frame 1. A motor 17 is fixedly installed at the output end of the motor 17, with one end of the motor 17 penetrating through the interior of the fixed frame 1. A driven wheel 33 is fixedly installed at one end of the motor 17. A transmission belt 15 is drivingly connected between the driven wheel 33 and the drive wheel 16. A conveyor belt 13 is drivingly connected to the outer surfaces of the first rotating shaft 12, the second rotating shaft 19, and the roller 3.

[0029] The operator starts the motor 17, which drives the second rotating shaft 19 to rotate inside the fixed frame 1. The second rotating shaft 19 drives the driven wheel 33 to rotate, which in turn drives the drive wheel 16 and the transmission belt 15 to rotate. The drive wheel 16 drives the first rotating shaft 12 to rotate inside the fixed frame 1. The rotation between the first rotating shaft 12 and the driven wheel 33 drives the conveyor belt 13 to rotate on the outer surface of the roller 3 and the fixed frame 1, and then the coal is conveyed by the conveyor belt 13.

[0030] Among them, a support plate 5 is fixedly installed at the bottom of the fixed frame 1, and a fixed plate 7 is fixedly installed between the two support plates 5.

[0031] Since a fixing plate 7 is fixedly installed between the two support plates 5, and the cooperation between the fixing plate 7 and the support plate 5 facilitates stable support for the fixing frame 1, the stability of the fixing frame 1 during use is guaranteed, and the efficiency of the fixing frame 1 is improved.

[0032] Among them, a reinforcing rib 6 is fixedly installed between the support plate 5 and the fixing plate 7, and the reinforcing rib 6 is triangular in shape.

[0033] Since the reinforcing rib 6 is triangular in shape between the support plate 5 and the fixing plate 7, and the triangle has the characteristic of stability, it ensures the stability of the support plate 5 and the fixing plate 7 during use and improves the efficiency of the support plate 5 and the fixing plate 7.

[0034] Among them, a fixing seat 9 is fixedly installed on the front of the support plate 5, a fixing block 10 is movably installed inside the fixing seat 9, and a toolbox 11 is fixedly installed on the front of the fixing block 10.

[0035] By holding the toolbox 11, the fixing block 10 is slowly inserted into the fixing seat 9. The fixing seat 9 limits and fixes the fixing block 10. By adding the toolbox 11, it is easier for the staff to take out and place maintenance tools in the toolbox 11, thereby improving the maintenance efficiency of the device.

[0036] Among them, the support base 18 is fixedly installed on the front of the fixed frame 1, and the interior of the support base 18 presents a U-shaped groove.

[0037] Since the inside of the support base 18 is in the form of a U-shaped groove on the front of the fixed frame 1, and the inside of the support base 18 is in contact with the outer surface of the motor 17, it is convenient to provide stable support for the motor 17, ensuring the stability of the motor 17 during use and improving the efficiency of the motor 17.

[0038] Among them, the emergency handle 8 is in the form of a U-shape on the top of the protective box 2, and the emergency handle 8 is in the form of a linear array.

[0039] Because the emergency handle 8 is in a U-shape on the top of the protective box 2, and the U-shape is ergonomic, it is easy to grasp the emergency handle 8 in time. At the same time, the emergency handle 8 is in a linear array on the top of the fixed frame 1, so that the staff can easily grab one.

[0040] The outer diameter of the fixing block 10 is equal to the inner diameter of the fixing seat 9, and the interior of the fixing seat 9 has a smooth surface design.

[0041] Since the outer diameter of the fixing block 10 is equal to the inner diameter of the fixing seat 9, and the interior of the fixing seat 9 has a smooth surface design, it is convenient for the staff to hold the toolbox 11 and insert the fixing block 10 into the interior of the fixing seat 9, thus ensuring the installation efficiency of the toolbox 11.

[0042] Working principle and usage process: When personnel enter the conveyor entrance, the inlet baffle 20 is pushed to rotate around the fixed rod 27, triggering the inner sensor 32 to send a linkage signal, which immediately cuts off the power to the conveyor mechanism to stop the machine. If the entrance detection system fails, the emergency handle 8 located on the top of the protective box 2 can be manually grabbed by personnel to prevent the body from continuing to move with the belt through mechanical locking. At the exit position, the limit bar 28 drives the exit stop plate 26 to form a physical barrier to prevent personnel from being transported to the danger zone.

[0043] According to the coal conveying situation, the staff needs to install the outlet stop plate 26. By holding the pull rod 31, the staff can pull the positioning block 29 to one side of the box 30 inside the protective box 2. The positioning block 29 will compress the spring 14 inside the box 30, so that the positioning block 29 passes through the inside of the protective box 2 and enters the inside of the box 30. Now, by holding the outlet stop plate 26, the staff can insert the limiting strip 28 into the inside of the protective box 2. When the limiting strip 28 is fully inside the protective box 2, the staff can release the pull rod 31, so that the spring 14 will compress the positioning block 29 inside the box 30, so that the positioning block 29 will quickly enter the inside of the fixed plate 23. The positioning block 29 will limit the limiting strip 28, thus completing the installation of the outlet stop plate 26.

[0044] The operator needs to adjust the tension of the conveyor belt 13 by rotating the handle 24. The handle 24 rotates the fixed plate 23, which in turn rotates the drive gear 22 inside the fixed frame 1. The drive gear 22 meshes with the driven gear 21, which in turn rotates the driven gear 21. The driven gear 21 then rotates the fixed shaft 25 and the handle 24 synchronously. The support plate 5 on the outer surface of the fixed frame 4 presses the conveyor belt 13, and the support plate 5 adjusts the tension of the conveyor belt 13, thus completing the adjustment of the tension of the transmission belt 15.
