Description

Technical Field

[0001] The invention relates to the technical field of mining belt conveyors, in particular to a mining belt conveyor capable of preventing lateral deviation. Background Art

[0002] Mining belt conveyors, as an indispensable and important equipment in mining, undertake the key task of material transportation. With compact structure and stable operation, they can efficiently transport ore, coal and other materials from one place to another. Mining belt conveyors also have many advantages, such as strong conveying capacity, strong adaptability, and low operating costs. It can not only adapt to various complex working environments, but also maintain stable performance under long-term continuous operation.

[0003] However, various faults may occur in the process of existing belt conveyors transporting large amounts of coal from the bottom of the mine to the ground. Conveyor belt deviation is one of the most common faults. When the conveyor belt deviates, a large amount of coal falls from one side of the conveyor belt, which directly affects production efficiency. The deviated conveyor belt not only affects production efficiency and equipment life, but may also pose a threat to the lives of miners. The fallen coal may injure the miners, and the deviated conveyor belt itself may cause more serious accidents due to loss of control.

[0004] In addition, the operating environment of the belt conveyor in the mine is harsh, and the conveyor belt is the key part for receiving materials. The coal blocks transported from the mining machinery to the conveyor drop port are accompanied by sharp angular objects (such as channel steel and angle steel, etc.), and there is a height difference between the drop port and the end-to-end connection between the two conveyor belts. Sharp objects can directly penetrate or tear the conveyor belt. They may directly penetrate the surface of the conveyor belt, causing material leakage, thereby affecting the conveying efficiency; more seriously, these sharp objects may also tear the conveyor belt, causing large-scale damage to the conveyor belt, and even paralyzing the entire conveying system. This damage not only increases maintenance costs, but may also cause safety accidents, posing a serious threat to the lives of miners.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0046] Please refer to Figures 1 to 10 As shown:

[0047] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a mining belt conveyor with anti-lateral deviation, including a transmission frame 1, belt rollers are installed on both sides of the transmission frame 1, a transmission belt 11 is connected to the belt rollers, an isolation cover 12 is arranged above the transmission belt 11, a cleaning device 13 is installed on one side of the transmission frame 1, a support plate 14 is arranged in the middle of the transmission frame 1, and also includes a detachable dust isolation mechanism 2, a longitudinal tear monitoring mechanism 3 and an anti-deviation mechanism 4;

[0048] Removable dust isolation mechanism 2;

[0049] The detachable dust-isolating mechanism 2 is arranged above the conveyor belt 11, and the detachable dust-isolating mechanism 2 is used for the quick disassembly and installation of the isolation cover 12;

[0050] Longitudinal tear detection mechanism 3;

[0051] The longitudinal tear detection mechanism 3 is arranged on the upper surface of the support plate 14, and the longitudinal tear detection mechanism 3 is used for longitudinal tear detection of the conveyor belt 11;

[0052] Anti-deviation mechanism 4;

[0053] The anti-deviation mechanism 4 is arranged on both sides of the support plate 14, and the anti-deviation mechanism 4 is used for anti-deviation detection of the conveyor belt 11;

[0054] Specifically, Figure 4 As shown, the bottom of the connecting bracket 21 is fixedly connected to the transmission frame 1, a card slot 22 is opened at the middle oblique angle of the connecting bracket 21, and limited blocks are symmetrically arranged at both ends of the isolation cover 12. The limited blocks on both sides of the isolation cover 12 are clamped in the card slot 22, and the end of the connecting bracket 21 away from the transmission frame 1 is fixedly connected to the limited pressure plate 23, and the limited pressure plate 23 is arranged above the conveyor belt 11. The middle of the transmission frame 1 is evenly fixedly connected with a bracket card plate 24, and the bottom of the support plate 14 is fixedly connected to the upper surface of the bracket card plate 24;

[0055] In this solution, multiple connecting brackets 21 are evenly fixed on both sides of the transmission frame 1. The limiting pressure plates 23 set on both sides of the connecting brackets 21 can prevent the two sides of the conveyor belt 11 from deflection. At the same time, multiple isolation covers 12 can be snapped into the card slots 22. Through modular splicing, it can not only be easier and faster during installation and disassembly, but also when the belt conveyor needs to be maintained or repaired, the staff can quickly remove the protective cover and easily install it back after completing the task, which greatly improves the work efficiency.

[0056] Compared with the traditional mineral conveyor belt 11, this design can not only effectively prevent the conveyor belt 11 from being punctured and damaged by objects suddenly falling from the external environment during transportation, but also further reduce the risk of longitudinal tearing of the conveyor belt 11. In addition, this design can also protect the belt conveyor from external factors such as dust and water stains to a certain extent, reduce equipment wear and failure rate, and thus extend the service life of the equipment.

[0057] Specifically, Figure 6 As shown, the middle belt roller 31 is arranged in the middle of the conveyor belt 11, and the outer surface of the middle belt roller 31 is in contact with the inner side of the upper part of the conveyor belt 11. The two ends of the middle belt roller 31 are symmetrically connected with the foreign body piercing detection plate 32. A retractable detection plate is arranged at the place where the upper end of the foreign body piercing detection plate 32 is in contact with the inner side of the conveyor belt 11, and a push switch is installed in the retractable detection plate.

[0058] Among them, a foreign body penetration detection plate 32 for horizontal detection is set on the inner side above the conveyor belt 11. When the conveyor belt 11 is in transportation, the sharp end of the object may pierce the surface of the conveyor belt 11 during transportation. A retractable detection plate is set on the inner side of the conveyor belt 11 above the foreign body penetration detection plate 32. A push switch is installed in the retractable detection plate. When the object piercing the conveyor belt 11 contacts the foreign body penetration detection plate 32 and squeezes the retractable detection plate of the foreign body penetration detection plate 32, the driving device driving the conveyor belt 11 will stop running by pressing the switch. The setting of the foreign body penetration detection plate 32 can prevent the conveyor belt 11 from being further damaged after the puncture.

[0059] The bottom surface of the foreign body piercing detection plate 32 is rotatably connected to the first push plate 33 and the second push plate 36 respectively. The first push plate 33 is rotatably connected to the first slider 34 at one end away from the foreign body piercing detection plate 32. The bottom of the first slider 34 is slidably connected to the upper surface of the support plate 14. The support plate 14 is evenly fixedly connected with a sliding shaft 37. The middle part of the first slider 34 is slidably connected to the outer surface of the sliding shaft 37. The end of the first slider 34 away from the first push plate 33 is fixedly connected to a buffer spring 35. The buffer spring 35 is sleeved on the outer surface of the sliding shaft 37. The end of the buffer spring 35 away from the first slider 34 is fixedly connected to the middle of the sliding shaft 37; the second push plate 36 is rotatably connected to the second slider 38 at one end away from the foreign body piercing detection plate 32. The middle part of the second slider 38 is symmetrically slidably connected to the outer surface of the sliding shaft 37. The end of the second slider 38 away from the second push plate 36 is fixedly connected to a return spring 39. The end of the return spring 39 away from the second slider 38 is fixedly connected to the sliding shaft 37.

[0060] In this solution, the first slider 34 and the second slider 38 are pushed by the first push plate 33 and the second push plate 36, which can not only effectively absorb the impact generated by the conveyor belt 11 during operation and reduce the wear and damage of the conveyor belt 11, but also make the conveyor belt 11 more stable during operation, reduce the deviation and jump caused by vibration and impact during transmission of the conveyor belt 11, and improve the stability and accuracy of transmission.

[0061] Further, if Figure 6 As shown, a connecting plate 301 is fixedly connected to one side of the second slider 38, a detection block 304 is fixedly connected to one end of the connecting plate 301 away from the second slider 38, fixed blocks 302 are symmetrically fixedly connected to both sides of the upper surface of the support plate 14, a resistor shaft 303 is fixedly connected to the middle of the fixed block 302, the middle of the detection block 304 is slidably connected to the outer surface of the resistor shaft 303, a junction box 305 is evenly fixedly installed on the upper surface of the support plate 14, and the detection block 304 and the resistor shaft 303 are respectively electrically connected in the junction box 305 through wires;

[0062] Among them, the other components of the longitudinal tear detection mechanism 3 except the belt middle roller 31 and the foreign body piercing detection plate 32 are symmetrically arranged on both sides of the belt middle roller 31;

[0063] In this solution, the second slider 38 on both sides of the upper surface of the support plate 14 is connected to the detection block 304 through a connecting plate 301 for fixing, and the fixed block 302 and the junction box 305 together form a sliding rheostat. When the conveyor belt 11 is transporting materials, by detecting the weight of the material on the conveyor belt 11 and comparing the weight on both sides of the middle roller 31 of the belt, the weight of the material on both sides of the conveyor belt 11 can be analyzed by sliding the detection block 304 on the resistance shaft 303, so that the force bearing state of the surface of the conveyor belt 11 can be obtained, so as to effectively detect whether the surface of the conveyor belt 11 is damaged, torn, etc.

[0064] On both sides of the upper surface of the base of the support plate 14, the second slider 38 is firmly connected to the fixed component of the detection block 304 through the connecting parts of the connecting plate 301. At the same time, the components from the fixed block 302 to the junction box 305 together constitute a high-precision sliding resistance sensor system; during the material transmission process, when the conveyor belt 11 is running with materials, the system can accurately detect the weight difference caused by the uneven distribution of materials on both sides of the conveyor belt. The sliding contact of the detection block 304 is flexibly displaced on the precision guide rail of the resistor shaft 303. The current change on both sides of the conveyor belt 11 due to the influence of gravity can be calculated through Ohm's law. Through this design, the weight distribution of materials on both sides of the conveyor belt can be analyzed and compared in real time. This process can not only accurately reflect the force-bearing state of the conveyor belt surface, but also effectively monitor whether there are abnormal conditions such as damage and tearing on the conveyor belt surface, thereby ensuring the stability and safety of the material transmission process.

[0065] Specifically, Fig.10 As shown, one end of the auxiliary plate 41 is rotatably connected to the upper surface of the second slider 38, and the other end of the auxiliary plate 41 is rotatably connected to an L-shaped connecting plate 42, and the L-shaped connecting plate 42 is rotatably connected to a beveled roller 43 on the side away from the auxiliary plate 41, and the outer surface of the beveled roller 43 is attached to the inner side of the conveyor belt 11; the end of the beveled roller 43 away from the L-shaped connecting plate 42 is rotatably connected to a connecting shaft 48, and a compression spring 44 is sleeved on the connecting shaft 48, and one end of the compression spring 44 is rotatably connected to the connecting shaft 48, and the other end of the compression spring 44 is fixedly connected to a pressure detection limit ring 45, and the middle part of the pressure detection limit ring 45 is slidably connected to the outer surface of the connecting shaft 48; belt limit blocks 47 are fixedly connected to the inner sides of both ends of the conveyor belt 11, and the lower surface of the belt limit block 47 is attached to the outer surface of the connecting shaft 48 close to the pressure detection limit ring 45, and the end of the connecting shaft 48 away from the belt limit block 47 is rotatably connected to a connecting frame 46;

[0066] Among them, inclined rollers 43 that can rotate at an angle as the conveyor belt 11 is subjected to gravity are arranged at the inner ends of the material being transported above the conveyor belt 11. The inclined rollers 43 are arranged so that the inclined rollers 43 can be more effectively fitted with the surface of the conveyor belt 11. At the same time, this solution makes improvements and innovations on the conveyor belt 11 body by symmetrically and fixedly arranging belt limit blocks 47 on both sides of the conveyor belt 11, and by effectively limiting the belt limit blocks 47 in the connecting shaft 48. When the conveyor belt 11 is transporting materials, when the conveyor belt 11 is deformed at a certain angle after bearing the load, the middle part of the conveyor belt 11 starts to move downward, and at this time, the two ends of the conveyor belt 11 start to slide downward along the surface of the inclined rollers 43. In this solution, a pressure detector 47 that can slide is arranged The measuring limit ring 45 detects the sliding distance and strength of the two ends of the conveyor belt 11. The detection of the pressure detection limit ring 45 can effectively obtain the displacement of the two sides of the conveyor belt 11 due to the gravity of the materials, and the extrusion pressure of the belt limit block 47 on the surface of the pressure detection limit ring 45. The extrusion pressure of the belt limit block 47 by the pressure detection limit ring 45 can preferentially monitor whether the surface of the conveyor belt 11 is damaged or longitudinally torn. When the conveyor belt 11 is bearing weight, the pressure detection limit rings 45 on both sides of the bottom of the conveyor belt 11 will be compared and the difference will be analyzed. When the difference reaches the set threshold, the controller electrically connected to the control center through the pressure detection limit ring 45 starts to start, so that the early warning device promptly notifies the post monitoring personnel to conduct investigation and analysis.

[0067] Compared with traditional mining conveyors, this solution can monitor the stress conditions on both sides of the conveyor belt 11 in real time by setting up in the middle and both sides of the bottom of the conveyor belt 11. Once abnormal stress or overload is found, measures can be taken immediately to prevent the conveyor belt 11 from being damaged due to excessive pressure or even causing safety accidents. At the same time, by monitoring the force, the operating state of the conveyor belt 11 can be adjusted in time to ensure that it can still maintain stable operation when the load changes. Moreover, the inclined rollers 43 at the bottom of both sides of the conveyor belt 11 can automatically adjust their inclination angles according to the material distribution and stress conditions, so that the conveyor belt 11 maintains dynamic balance. This adjustment helps to reduce the vibration and deviation of the conveyor belt 11 during operation, and reduce the risk of longitudinal tearing caused by friction and wear.

[0068] Among them, one end of the connecting frame 46 away from the connecting shaft 48 is fixedly connected to the limiting pressure plate 23;

[0069] By arranging limiting pressure plates 23 on both sides of the conveyor belt 11, not only can the two sides of the conveyor belt 11 be limited, but also the spilling of materials can be prevented. The design of the limiting pressure plates 23 also fully takes into account the transportation safety of materials. During the transmission process, the limiting pressure plates 23 can effectively block materials that may be spilled due to various reasons, thereby avoiding waste and loss of materials. This not only improves the utilization rate of materials, but also reduces the production cost of the enterprise. Moreover, the limiting pressure plates 23 can also accurately limit the position of both sides of the conveyor belt 11 to ensure that it does not produce excessive deviation or shaking during operation. This precise limiting effect greatly improves the operating stability of the conveyor belt 11 and provides a strong guarantee for the smooth transmission of materials.

[0070] The specific implementation process in the above embodiment is as follows:

[0071] 1. Preparation before startup

[0072] Check the device status:

[0073] First, check whether the conveyor belt 11 is intact, whether the chain is loose, and whether the screws of each component are tightened.

[0074] Check whether the safety protection facilities such as guardrails, nets, isolation covers 12 are complete, reliable and intact.

[0075] Check whether the pull-wire switches, deviation protection devices, braking devices and other safety protection devices are complete, effective and intact.

[0076] Since multiple connecting brackets 21 are evenly fixed on both sides of the transmission frame 1 in this solution, the limiting pressure plates 23 arranged on both sides of the connecting brackets 21 can be used to prevent the two sides of the conveyor belt 11 from deflection. At the same time, multiple isolation covers 12 can be engaged in the card slots 22. Through modular splicing, not only can the installation and disassembly process be simpler and faster, but also when the belt conveyor needs to be maintained or overhauled, the staff can quickly remove the protective cover and easily install it back after completing the task, thereby improving the working efficiency of the conveyor belt 11;

[0077] Compared with the traditional mineral conveyor belt 11, this solution, by providing a quick-detachable isolation cover 12, can not only effectively prevent the conveyor belt 11 from being punctured and damaged by objects suddenly falling from the external environment during transportation, but can also further reduce the risk of longitudinal tearing of the conveyor belt 11. In addition, the design of this solution can also protect the belt conveyor from erosion by external factors such as dust and water stains to a certain extent, reduce equipment wear and failure rate, and thus extend the service life of the equipment.

[0078] Next, to connect the power supply, first turn on the main power switch, check whether the power supply to the device is normally supplied, and confirm whether the power indicator light is on, indicating that the power supply has been normally connected, ensure that the voltage meets the requirements, and the wiring is correct to avoid damage to the equipment due to current problems.

[0079] Before starting, you must get in touch with the tail and each loading point, check whether the power indicator lights of the inverter, PLC and other equipment are on, and whether the display panel is normal (no fault code is displayed). Start only after receiving the correct signal. Do not start if the signal is unclear;

[0080] Specifically, in this solution, inclined rollers 43 are arranged at both ends of the inner side of the conveyor belt 11 for conveying materials, and the inclined rollers 43 can rotate at an angle as the conveyor belt 11 is subjected to gravity. The inclined rollers 43 can be arranged to more effectively fit the surface of the conveyor belt 11. At the same time, this solution makes improvements and innovations on the conveyor belt 11 body, by symmetrically and fixedly arranging belt limit blocks 47 on both sides of the conveyor belt 11, and by effectively limiting the belt limit blocks 47 in the connecting shaft 48. When the conveyor belt 11 is transmitting materials, when the conveyor belt 11 is deformed at a certain angle after bearing the load, the middle part of the conveyor belt 11 starts to move downward, and at this time, the two ends of the conveyor belt 11 start to slide downward along the surface of the inclined rollers 43. In this solution, a sliding pressure plate 47 is arranged The force detection limit ring 45 detects the sliding distance force at both ends of the conveyor belt 11. The detection of the pressure detection limit ring 45 can effectively obtain the displacement of both sides of the conveyor belt 11 due to the gravity of the materials, and the extrusion pressure of the belt limit block 47 on the surface of the pressure detection limit ring 45. The extrusion pressure of the belt limit block 47 by the pressure detection limit ring 45 can be used to preferentially monitor whether the surface of the conveyor belt 11 is damaged or longitudinally torn. When the conveyor belt 11 is bearing weight, the pressure detection limit rings 45 on both sides of the bottom of the conveyor belt 11 will be compared and the difference will be analyzed. When the difference reaches the set threshold, the controller electrically connected to the control center through the pressure detection limit ring 45 starts to start, so that the early warning device promptly notifies the post monitoring personnel to conduct investigation and analysis.

[0081] Compared with traditional mining conveyors, this solution can monitor the stress conditions on both sides of the conveyor belt 11 in real time by setting up in the middle and both sides of the bottom of the conveyor belt 11. Once abnormal stress or overload is found, measures can be taken immediately to prevent the conveyor belt 11 from being damaged due to excessive pressure or even causing safety accidents. At the same time, by monitoring the force, the operating state of the conveyor belt 11 can be adjusted in time to ensure that it can still maintain stable operation when the load changes. Moreover, the inclined rollers 43 at the bottom of both sides of the conveyor belt 11 can automatically adjust their inclination angles according to the material distribution and stress conditions, so that the conveyor belt 11 maintains dynamic balance. This adjustment helps to reduce the vibration and deviation of the conveyor belt 11 during operation, and reduce the risk of longitudinal tearing caused by friction and wear.

[0082] 2. Startup Operation

[0083] Issue a start signal: When starting, a signal bell must be rung to draw attention to the start of the belt conveyor and warn personnel to leave the rotating part of the conveyor.

[0084] No-load start: To prevent the coal conveying system from being blocked and the motor from starting under load, the belt coal conveyor should be started without load and the operation of the equipment should be observed. After starting the motor, observe the operation of the head transmission device, each roller, as well as the working conditions of the sweeper and other auxiliary devices.

[0085] Start against the material flow direction: Start the belt conveyor in the opposite direction of material flow (or feed direction) at a certain time interval. For example, start the downstream belt first, and then start the upstream belt after a delay.

[0086] Reverse coal flow sequence start:

[0087] To prevent the coal conveying system from being blocked and the motor from starting under load, the belt conveyor should be started in the following reverse coal flow sequence.

[0088] (1) Start the belt conveyor at the end.

[0089] (2) After a delay of a certain period (e.g. 5 seconds), start the belt conveyor in the previous section.

[0090] (3) And so on, until all belt conveyors are started.

[0091] Gradual loading: After all belt conveyors start up normally without load, you can start loading coal onto the belt conveyor. When loading, start with a small amount and slowly increase to the normal working amount to ensure a smooth transition of the equipment.

[0092] 3. Loading and Adjustment

[0093] Progressive loading:

[0094] Only after all the equipment on the entire coal transportation system starts normally without load, can the belt conveyor be loaded with coal for transportation, starting with a small amount of material and slowly increasing to the normal working amount to ensure a smooth transition of the equipment. In this solution, the first slider 34 and the second slider 38 are pushed by the first push plate 33 and the second push plate 36, which can not only effectively absorb the impact generated by the conveyor belt 11 during operation and reduce the wear and damage of the conveyor belt 11, but also make the conveyor belt 11 more stable during operation, reduce the deviation and jump caused by vibration and impact during transmission of the conveyor belt 11, and improve the stability and accuracy of transmission.

[0095] Furthermore, check the tension of the conveyor belt and pay attention to the operation of the conveyor belt after loading. If any deviation is found, adjust it immediately. Specifically, by setting limit pressure plates 23 on both sides of the conveyor belt 11, not only can the two sides of the conveyor belt 11 be limited, but also the spillage of materials can be prevented. The design of the limit pressure plates 23 also fully considers the transportation safety of materials. During the transmission process, the limit pressure plates 23 can effectively block materials that may be spilled due to various reasons, thereby avoiding waste and loss of materials. This not only improves the utilization rate of materials, but also reduces the production cost of the enterprise. Moreover, the limit pressure plates 23 can also accurately limit the position of both sides of the conveyor belt 11 to ensure that it does not produce excessive deviation or shaking during operation. This precise limiting effect greatly improves the operating stability of the conveyor belt 11, and provides a strong guarantee for the smooth transmission of materials.

[0096] 4. Shutdown Operation

[0097] Preparation before shutdown:

[0098] In order to leave no residual material on the conveyor belt, the machine should be shut down in the order of coal flow.

[0099] (1) First stop loading coal.

[0100] (2) After a delay of a certain period of time (e.g. 10 seconds), stop the frontmost belt conveyor.

[0101] (3) And so on, until all the belt conveyors stop.

[0102] Before shutting down, clear the cargo on the conveyor belt, clean all parts, and keep the surrounding environment clean.

[0103] To cut off the power supply: cut off the power supply of the starter and lock the operating handle to ensure the safe shutdown of the equipment. After shutdown, conduct a comprehensive inspection and maintenance of the belt conveyor, and check the belt wear, tension, and rotation flexibility of the roller again.

[0104] To sum up, the present invention adopts a modular disassembly and installation method for the isolation cover 12, which can not only protect the belt conveyor from erosion by external factors such as dust and water stains to a certain extent, but also the staff can quickly remove the protective cover and easily install it back after completing the task, thereby improving work efficiency. At the same time, the design of the isolation cover 12 can also reduce the wear of the conveyor belt 11 and the equipment failure rate, thereby extending the service life of the equipment; compared with the traditional design, the present invention sets a detection mechanism in the middle and both sides of the bottom of the conveyor belt 11, which can not only effectively prevent the conveyor belt 11 from tilting during transportation, but also to a certain extent prevent the risk of longitudinal tearing of the conveyor belt 11. Through real-time force monitoring of the bottom of the conveyor belt 11 in this scheme, not only the damage rate of the equipment during transportation can be reduced, but also the surface of the conveyor belt can be effectively monitored for damage, tearing and other abnormal conditions, thereby ensuring the stability and safety of the material transmission process.
