Description

Technical Field

[0001] This invention relates to the technical field of belt tear detection, and more particularly to a belt crack detection device. Background Technology

[0002] Conveyor belts, as conveying devices used in coal mining to replace manual handling and transportation of coal, reduce labor costs, and accelerate the progress of coal mining operations, play an irreplaceable role in coal mining. They are one of the essential pieces of equipment in coal production, playing a vital role in improving production efficiency, ensuring operational safety, and protecting coal quality.

[0003] Conveyor belts are subjected to significant tensile and frictional forces during use. Prolonged operation can lead to belt aging and wear. Crack inspection is used to detect and address cracks on the belt surface in a timely manner, preventing cracks from expanding and causing belt breakage, which would affect production and safety. Crack inspection can also help determine the belt's service life and health condition, allowing for timely replacement or repair of damaged parts and extending the conveyor belt's lifespan.

[0004] Traditional belt crack detection relies on visual and tactile inspections. While simple, these methods depend on the subjective judgment of the staff, which can lead to subjective errors in the results. Furthermore, they cannot monitor the conveyor belt in real time during its use, preventing timely detection of cracks. This can result in further damage to the conveyor belt, necessitating replacement of the entire belt and incurring high repair costs. Summary of the Invention

[0039] Example 1

[0040] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a belt crack detection device, including: a conveying component 100, including a conveyor belt 101 and support brackets 102 disposed at both ends of the conveyor belt 101; a monitoring component 200, including a first connecting frame 201 disposed on the conveyor belt 101, a cleaning component 202 disposed on the first connecting frame 201, a detection component 203 disposed on the cleaning component 202, a marking component 204 disposed on the detection component 203, and an alarm component 205 disposed on the detection component 203; the support brackets 102 are symmetrically arranged, and the first connecting frame 201 is located below the conveyor belt 101.

[0041] The support brackets 102 are located on both sides of the conveyor belt 101, and are symmetrically arranged to support the conveyor belt 101, thus facilitating its use. The monitoring component 200 is located below the conveyor belt 101 and is used to monitor the operating status of the conveyor belt 101 in real time during use. The first connecting frame 201 is located below the conveyor belt 101 and is used to install and store the monitoring component 200, facilitating its operation. The legs on both sides of the first connecting frame 201 are telescopically adjustable to adjust the height of the monitoring component 200, allowing it to match conveyor belts 101 of different heights and increasing its applicability. There are four cleaning components 202, and two adjacent cleaning components 202 are arranged symmetrically in two sets, which can clean the inner surface of the conveyor belt 101. The outer sides are cleaned to facilitate subsequent inspection of the conveyor belt 101 and prevent impurities from adhering to the surface of the conveyor belt 101, which could lead to unstable inspection data. The detection component 203 is located between the two sets of cleaning components 202 and is used to monitor the operating status of the conveyor belt 101 in real time. The marking component 204 is located inside the detection component 203 and is used to mark the damaged areas of the conveyor belt 101 detected by the detection component 203, thereby facilitating maintenance personnel to inspect the conveyor belt 101. The alarm component 205 is located above the detection component 203 and can issue an alarm in a timely manner after the detection component 203 detects damage to the conveyor belt 101, so that maintenance personnel can be aware of the damage to the conveyor belt 101 in a timely manner and deal with the damage in real time, preventing the conveyor belt 101 from being damaged further if cracks are not dealt with in time, thus saving maintenance costs.

[0042] The cleaning assembly 202 includes a linkage shaft 202a mounted on the first connecting frame 201, a linkage frame 202b mounted on the linkage shaft 202a, and a cleaning roller 202c mounted on the linkage shaft 202a. The linkage shaft 202a is rotatably connected to the first connecting frame 201, and a torsion spring is provided between the linkage shaft 202a and the first connecting frame 201. The cleaning roller 202c is rotatably connected to the linkage frame 202b, and the cleaning roller 202c is in contact with the surface of the conveyor belt 101. A cleaning cover 202c-1 is sleeved on the cleaning roller 202c, and the cleaning cover 202c-1 is in contact with the conveyor belt 101.

[0043] Specifically, there are eight linkage shafts 202a, and adjacent linkage shafts 202a are symmetrically arranged. The linkage shafts 202a are located inside the first connecting frame 201, and are rotatably connected to the first connecting frame 201. A torsion spring is installed between the linkage shafts 202a and the first connecting frame 201. The torsion spring facilitates adjustment of the gap between the linkage frame bodies 202b on two adjacent linkage shafts 202a, thereby facilitating the cleaning of conveyor belts 101 of different thicknesses. The linkage frame body 202b is located on the linkage shaft 202a, and is fixedly connected to the linkage shaft 202a. The linkage frame body 202b serves as a connection between the linkage shaft 202a and the cleaning roller 202c. The purpose of adding a linkage frame 202b to the roller 202c is to increase the distance between the cleaning roller 202c and the linkage shaft 202a, thereby increasing the adjustability of the cleaning roller 202c and improving its applicability. The cleaning roller 202c is located at the end of the linkage frame 202b, and the cleaning roller 202c and the linkage frame 202b are rotatably connected. A cleaning cloth 202c-1 is fitted on the cleaning roller 202c. The conveyor belt 101 passes between the two cleaning rollers 202c. The movement of the conveyor belt 101 drives the cleaning roller 202c to rotate on the linkage frame 202b, so that the cleaning cloth 202c-1 wipes the dust and impurities on the surface of the conveyor belt 101, achieving the effect of cleaning the conveyor belt 101.

[0044] Furthermore, two sets of linkage shafts 202a are respectively set on both sides of the first connecting frame 201. This design can increase the applicability of the conveyor belt 101. Regardless of whether the conveyor belt 101 rotates clockwise or counterclockwise, the cleaning rollers 202c on the linkage shafts 202a can clean the conveyor belt 101, keeping it clean and tidy. At the same time, the purpose of setting two sets of cleaning components 202 is to make it easier to clean the conveyor belt 101 and to provide accurate information to the detection component 203, so that the detection component 203 can detect the conveyor belt 101 more accurately and improve the stability of the detection component 203.

[0045] Operation process: When the conveyor belt 101 is running, the conveyor belt 101 passes between the two linkage shafts 202a. The linkage shafts 202a, along with the elastic force of the torsion spring, push the cleaning rollers 202c on the linkage frame 202b to adhere to the conveyor belt 101. As the conveyor belt 101 moves, the cleaning rollers 202c on the linkage frame 202b rotate. The cleaning cloth 202c-1 cleans the impurities on the conveyor belt 101, making it convenient for the detection component 203 to detect the conveyor belt 101.

[0046] Example 2

[0047] Reference Figures 4-6 This is the second embodiment of the present invention, which is based on the previous embodiment, except that: the detection component 203 includes a detection housing 203a disposed on the first connecting frame 201, a detection connecting plate 203b disposed on the detection housing 203a, a detection connecting rod 203c disposed on the detection connecting plate 203b, a detection protrusion 203d disposed on the detection connecting rod 203c, and a reset spring 203e sleeved on the detection protrusion 203d; the detection protrusion 203d is located at the end of the detection connecting rod 203c, and the detection protrusion 203d is in contact with the conveyor belt 101.

[0048] The rest of the structure is the same as in Example 1.

[0049] The detection housing 203a is symmetrically arranged on the first connecting frame 201, with each housing corresponding to the inner and outer sides of the conveyor belt 101. The detection housing 203a is welded to the first connecting frame 201, and its interior is hollow. The detection connecting plate 203b is located inside the detection housing 203a and is detachable from it. The detection connecting plate 203b serves not only as a mounting and storage component for the detection connecting rod 203c but also as the sole entry and exit point for the detection housing 203a, thus facilitating its maintenance and inspection. The number of detection connecting rods 203c... There are multiple detection links, and the detection link 203c and the detection plate 203b are slidably connected. The reset spring 203e is sleeved on the end of the detection link 203c for resetting the detection link 203c. The detection protrusion 203d is located at the end of the detection link 203c and is in contact with the conveyor belt 101. According to the cracks generated on the surface of the conveyor belt 101, the surface of the cracks is irregular. The detection protrusion 203d moves along the conveyor belt 101 and passes through the cracks of the conveyor belt 101. Then, the detection protrusion 203d drives the detection link 203c to vibrate, so that the detection link 203c drives the marking component 204 to mark the damaged area, thereby facilitating the maintenance personnel to inspect the conveyor belt 101.

[0050] The length of the detection link 203c is irregularly arranged, the detection housing 203a is symmetrically arranged on the first link 201, and the detection protrusion 203d on the detection housing 203a is in contact with both sides of the conveyor belt 101.

[0051] Specifically, the cross-section of the detection link 203c is Z-shaped with a 90-degree flip. The detection link 203c can be divided into three parts: a first vertical link, a horizontal link, and a second vertical link. The first vertical link of the detection link 203c penetrates the detection plate 203b, and the lengths of the first vertical links on the detection link 203c are equal and predetermined. The first vertical link of the detection link 203c is perpendicular to the detection plate 203b, and there is a sliding connection between the first vertical link of the detection link 203c and the detection plate 203b. A return spring 203e is fitted at one end of the first vertical link of the detection link 203c inside the detection plate 203b. The length of the horizontal bar of the rod 203c controls the overall length of the detection link 203c. By varying the length of the horizontal bar of the detection link 203c, different rule settings for the detection link 203c can be achieved. The second vertical bar of the detection link 203c is located at the end of the horizontal bar. The length of the second vertical bar of the detection link 203c is equal and predetermined. The second vertical bar of the detection link 203c is perpendicular to the conveyor belt 101, and the detection protrusion 203d is located at the end of the second vertical bar of the detection link 203c. This design facilitates the contact between the detection protrusion 203d and the conveyor belt 101, thereby achieving the detection of the conveyor belt 101.

[0052] Furthermore, the cross-section of the detection bump 203d is circular. This greatly reduces the sharpness of the detection bump 203d, avoiding secondary damage when the detection bump 203d is inspecting the conveyor belt 101. Moreover, the circular detection bump 203d can more sensitively detect damage on the conveyor belt 101, thereby achieving accurate detection and improving detection accuracy.

[0053] Furthermore, the detection linkage 203c is symmetrically arranged along the centerline of the detection housing 203a, so that the damaged area of ​​the conveyor belt 101 can be detected a second time by the detection protrusion 203d. In this way, the marking component 204 can mark the beginning and end of the crack respectively. It can not only double-mark the crack, but also expand the damaged area to a specified range. Compared with the ordinary marking method, this marking can be more accurate. At the same time, it avoids the marking liquid from contaminating the crack, making it easier for maintenance personnel to inspect the conveyor belt 101.

[0054] Operation process: When the conveyor belt 101 is running, it is cleaned by the cleaning component 202, so that its outer surface is kept clean and free of impurities. After cleaning, the conveyor belt 101 continues to move with the driving force. The cracks on the outer surface of the conveyor belt 101 are detected by the detection protrusion 203d. The detection protrusion 203d contacts the crack, and after increasing the friction, the detection protrusion 203d drives the detection connecting rod 203c to slide on the detection connecting plate 203b. At the same time, the detection connecting rod 203c compresses the reset spring 203e during the sliding process. The reset spring 203e drives the detection connecting rod 203c to reset. This process is repeated to provide a signal to the marking component 204, so that the marking component 204 can be started.

[0055] Example 3

[0056] Reference Figures 4-6 This is the third embodiment of the present invention, which differs from the second embodiment in that: the marking component 204 includes a receiving cavity 204a disposed within the detection housing 203a, a power storage member 204b disposed on the receiving cavity 204a, a first connecting pipe 204c disposed on the power storage member 204b, and a nozzle 204d disposed on the first connecting pipe 204c; the receiving cavity 204a is located on the inner wall of the detection housing 203a, the nozzle 204d is located below the first connecting pipe 204c, the receiving cavity 204a is filled with a color developing solution, and two adjacent receiving cavities 204a are connected by a conductive connecting pipe.

[0057] The rest of the structure is the same as in Example 2.

[0058] The accommodating cavity 204a is located inside the detection housing 203a. The middle of the accommodating cavity 204a is hollow and used to store the marking solution. The number and position of the accommodating cavities 204a correspond to those of the detection housing 203a. The two accommodating cavities 204a are connected by a conductive connecting pipe and are interconnected by the conductive connecting pipe. The number of first connecting pipes 204c corresponds to the number of detection connecting rods 203c. The first connecting pipes 204c penetrate the detection connecting plate 203b and are used to transport the marking solution. The nozzle 204d is located at one end of the detection connecting plate 203b from which the first connecting pipe 204c extends. The energy storage component 204b enables the marking solution to be sprayed out from the nozzle 204d to mark the cracks in the conveyor belt 101.

[0059] The energy storage component 204b includes an energy storage tube 204b-1 disposed on the accommodating cavity 204a, the accommodating cavity 204a and the energy storage tube 204b-1 being connected by a connecting conduit 204b-2, an energy storage slide rod 204b-3 disposed within the energy storage tube 204b-1, and an energy storage piston 204b-4 disposed on the energy storage slide rod 204b-3; a one-way valve is disposed within the connecting conduit 204b-2, and the energy storage slide rod 204b-3 and the energy storage tube 204b-1 are slidably connected.

[0060] Specifically, the accumulator tube 204b-1 is located between the accommodating cavity 204a and the detection link 203c. The accumulator tube 204b-1 and the accommodating cavity 204a are connected by a connecting conduit 204b-2, and the accumulator tube 204b-1 and the accommodating cavity 204a are interconnected. At the same time, a one-way valve is provided in the connecting conduit 204b-2. The one-way valve can control the flow of the marking solution from the accommodating cavity 204a into the accumulator tube 204b-1, and prevent it from flowing back from the accumulator tube 204b-1 into the accommodating cavity 204a. The accumulator slide rod 204b-3 is located at the end of the first vertical rod of the detection link 203c. The accumulator slide rod 204b-3 and the detection link 203c are slidably connected. The movement of the accumulator slide rod 204b-3 and the accumulator tube 204b-1 is similar to that of a piston.

[0061] Operation process: When the detection protrusion 203d at the end of the detection link 203c detects damage to the conveyor belt 101, the detection protrusion 203d moves up and down, causing the detection link 203c to move up and down. At this time, the detection protrusion 203d moves to the concave part of the conveyor belt 101, and the detection link 203c drives the energy storage slide 204b-3 to slide inside the energy storage tube 204b-1, so that a negative pressure is generated inside the energy storage tube 204b-1, and the marking solution moves along the negative pressure. The solution enters the storage tube 204b-1. When the detection protrusion 203d moves to the highest point of the conveyor belt 101, the detection connecting rod 203c drives the storage slide rod 204b-3 to slide on the storage tube 204b-1 and squeeze the storage tube 204b-1. This causes the marking solution in the storage tube 204b-1 to be sprayed out from the nozzle 204d along the first connecting pipe 204c onto the conveyor belt 101, thereby marking the cracks in the conveyor belt 101.

[0062] Example 4

[0063] Reference Figures 1-6 This is the third embodiment of the present invention, which differs from the third embodiment in that:

[0064] The alarm assembly 205 includes an alarm connection cavity 205a disposed on one of the accommodating cavities 204a, a response connection cavity 205b disposed on the alarm connection cavity 205a, and a sensing element 205c disposed on the alarm connection cavity 205a.

[0065] The rest of the structure is the same as in Example 3.

[0066] The alarm cavity 205a is located above the upper accommodating cavity 204a and is interconnected with the accommodating cavity 204a. The response cavity 205b is located above the alarm cavity 205a and is interconnected with the alarm cavity 205a. The alarm cavity 205a serves as the marking status of the sensing marking component 204 and sends a signal to the response cavity 205b, which then issues an alarm based on the real-time situation.

[0067] The upper end of the response cavity 205b is provided with an exhaust port 205b-1, and a spring is installed inside the exhaust port 205b-1. The lower end of the response cavity 205b is provided with an air inlet port 205b-2 that communicates with the alarm cavity 205a.

[0068] The upper exhaust port 205b-1 of the response cavity 205b is equipped with a spring. Gas is introduced into the response cavity 205b through the air inlet 205b-2, which increases the gas flow rate in the response cavity 205b. When the gas is discharged through the exhaust port 205b-1, it passes through the spring and then emits an audible alert.

[0069] The sensing element 205c includes a blocking protrusion 205c-1 disposed on the alarm connection cavity 205a, a blocking slide rod 205c-2 disposed on the blocking protrusion 205c-1, and a blocking float 205c-3 disposed on the blocking slide rod 205c-2; the blocking protrusion 205c-1 is adapted to the air inlet 205b-2, the blocking slide rod 205c-2 is slidably connected to the alarm connection cavity 205a, and the blocking slide rod 205c-2 passes through the alarm connection cavity 205a and the receiving cavity 204a, and the blocking float 205c-3 is disposed at one end of the blocking slide rod 205c-2 located in the receiving cavity 204a.

[0070] Operation process: When the crack generated by the conveyor belt 101 is marked by the marking component 204, the water level in the accommodating cavity 204a drops. At this time, the blocking float 205c-3 is affected by the drop in water level, which pulls the blocking slide bar 205c-2 to slide on the accommodating cavity 204a, causing a gap to be created between the blocking protrusion 205c-1 and the air inlet 205b-2. Gas flows from the alarm connecting cavity 205a into the response connecting cavity 205b, and then the gas is discharged from the exhaust port 205b-1 through the response connecting cavity 205b. At this time, the spring in the exhaust port 205b-1 emits an audible alarm so that maintenance personnel can know the location information.
