Description

Technical Field

[0001] The invention belongs to the technical field of automated conveyor lines, in particular to a wear resistance detection device for a belt conveyor. Background Art

[0002] The wear resistance testing device for belt conveyors is a device specifically used to evaluate the wear resistance of conveyor belt materials. It usually simulates the friction conditions between the conveyor belt and the material during actual operation, allowing the conveyor belt sample and the friction medium to move relative to each other at a set speed. At the same time, sensors are used to monitor parameters such as the wear amount, friction coefficient, and surface morphology changes of the sample in real time. Finally, the wear resistance level of the conveyor belt is determined based on the test data, providing a basis for its selection, quality control, and service life evaluation.

[0003] In order to better simulate the friction between the belt and different materials, during the friction detection process, it is necessary to switch the friction heads of different roughness to contact the belt, and sometimes the pressure of the friction head contacting the belt will also be different. For example, publication number CN119375078A discloses a wear resistance performance detection device for a belt conveyor, including a friction mechanism, which includes an annular friction element and a driving member that drives the annular friction element to rotate circumferentially; abrasive particles of different specifications can be discharged through the abrasive particle discharge mechanism to adjust the roughness of the abrasive particle wear resistance detection, so that the wear resistance detection of the belt can be realized through a variety of different roughness, and the discharge amount of the abrasive particles can be accurately controlled.

[0004] Although the roughness of the friction element can be adjusted by the abrasive particle discharge mechanism, the belt friction surface will be worn in actual use. After adjusting the roughness of the friction element, if the friction test is continued at the worn part, it will affect the final test result. The above application document cannot automatically switch the belt. The operator needs to manually remove the belt after friction and fix another set of unfrictioned belts before continuing the test. It is more troublesome and reduces the overall efficiency of the test. Therefore, a wear resistance detection device for a belt conveyor is proposed to address the above problem.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides a wear resistance detection device for a belt conveyor, comprising a base 100, and further comprising: a fixed plate 200, the inner wall of the fixed plate 200 is provided with a friction module 400 through a driving mechanism, the fixed plate 200 is provided with a chip removal mechanism 500, and the outer wall of the base 100 is provided with a conveying mechanism 300; Among them, the conveying mechanism 300 includes a fixed block 301, the inner wall of the fixed block 301 is provided with a guide groove 306, the inner wall of the fixed block 301 is slidably connected to the moving block 302, the inner wall of the moving block 302 is elastically connected to the splint 304 through the reset spring 303, the outer wall of the splint 304 is fixedly connected to the guide rod 305, the outer wall of the moving block 302 is fixedly connected to the moving rod 310, and the inner wall of the fixed plate 200 is slidably connected to the trapezoidal block 311.

[0021] The above scheme is adopted: the side wall of the friction module 400 is connected to four groups of friction heads through four groups of micro motors, and the particle roughness of the surface of each group of friction heads is different. By switching the friction heads to contact the belt and driving it to rotate through the micro motors, the wear resistance test of the belt under different friction degrees can be simulated; on the one hand, the conveying mechanism 300 can fix the belt to prevent it from shifting during the friction process, and on the other hand, when a group of friction heads is rubbed and the friction heads need to be replaced for testing, the belt is automatically pulled to move, and the unrubbed part of the belt surface is automatically moved to the bottom of the friction head to prevent multiple friction heads from always rubbing with the same place on the belt, affecting the wear resistance test results. There is no need for operators to manually move the belt, which reduces the process of manual intervention and has a high degree of automation; the two groups of splints 304 in the moving block 302 can clamp and fix one end of the belt, and the moving block 302 is movable, and the belt is pulled to move by the clamping force of the splint 304 on the belt.

[0022] like Figures 1 to 2 As shown, the top outer wall of the base 100 is fixedly connected to a fixing module 600, the outer wall of the base 100 is fixedly connected to a placement table 700, the outer wall of the base 100 is fixedly connected to a belt roller 800, and the outer wall of the fixing plate 200 is fixedly connected to a cylinder 900.

[0023] The above scheme is adopted: the fixing module 600 is provided with two sets of upper and lower clamping plates, and the upper clamping plate can be driven to move up and down by existing technologies such as electric push rods, providing high-pressure tightening force to one end of the belt for fixing, and automatically completing the clamping operation; the belt can be wound and rolled on the belt roller 800, and when the conveying mechanism 300 pulls the belt, the belt can rotate synchronously with the belt roller 800 for conveying. After the belt is pulled out, it passes between the placement table 700 and the two sets of clamping plates 304 and is fixed in the fixing module 600. The friction head of the friction module 400 is fixed to the placement table 700. The friction module 400 can be moved up and down by the cylinder 900 and the driving mechanism. Friction detection can be performed when it moves down to contact the belt surface on the placement table 700.

[0024] like Figures 2 to 5 As shown, the conveying mechanism 300 further includes a slide bar 307 , the inner wall of the slide bar 307 is elastically connected to a protrusion 308 via a connecting spring 309 , and an inner wall of the fixing block 301 is provided with an inclined groove 312 .

[0025] The above solution is adopted: the guide rod 305 passes through the outer wall of the moving block 302, and the outer wall of the moving block 302 is vertically opened, so that the guide rod 305 can only move vertically in the empty slot, and the guide rod 305 will always be in contact with the inner wall of the guide groove 306. The guide groove 306 is opened in a triangular shape. When the guide rod 305 contacts the horizontal straight section of the guide groove 306, the moving block 302 moves so that the guide rod 305 drives the clamping plate 304 to remain in the middle and clamp the belt. At this time, the return spring 303 is in a stretched state; and the moving block 302 02 moves to when the guide rod 305 contacts the vertical straight section of the guide groove 306, the guide rod 305 can move vertically along the guide groove 306 and the empty groove on the outer wall of the moving block 302, and the two sets of clamps 304 move to both sides and reset under the elastic force of the reset spring 303; when the moving block 302 moves to when the guide rod 305 is in the inclined section of the guide groove 306, the inclined section will squeeze the guide rod 305, and during the movement of the moving block 302, it will drive the two sets of clamps 304 to move toward the middle at the same time, and clamp the belt when it moves to the very end.

[0026] The sliding rod 307 is arranged on the outer wall of the side of the splint 304 away from the guide rod 305, and passes through the outer wall of the other side of the moving block 302, and is slidably connected to the empty groove of the outer wall of this side. It can only move vertically. The outer wall of the moving block 302 fits the inner wall of the fixed block 301. When the moving block 302 moves to the point where the protrusion 308 does not contact the inner wall of the inclined groove 312, the protrusion 308 is squeezed by the inner wall of the fixed block 301 and is always in the inner wall of the sliding rod 307, compressing the connecting spring 309.

[0027] like Figures 2 to 5 As shown, the fixed block 301 is fixedly connected to the top outer wall of the base 100, the splint 304 is slidably connected to the inner wall of the movable block 302, the guide rod 305 passes through and is slidably connected to the inner wall of the movable block 302, the guide rod 305 contacts the inner wall of the guide groove 306, the protrusion 308 is slidably connected to the inner wall of the slide rod 307, and the movable rod 310 is slidably connected to the inner wall of the fixed block 301.

[0028] The above scheme is adopted: when the cylinder 900 and the driving mechanism drive the friction module 400 to be at the bottom and perform friction detection, the two sets of clamping plates 304 are in a state of clamping the belt, and the cylinder 900 drives the driving mechanism and the friction module 400 to move upward. After disengaging from the belt, the moving block 302 will move toward the side of the fixed module 600 under the action of the trapezoidal block 311 and the moving rod 310, driving the clamping plate 304 and the guide rod 305 to move synchronously, and the guide rod 305 moves straight along the horizontal section of the guide groove 306, keeping the clamping state of the clamping plate 304 on the belt, and then pulling the belt toward the side of the fixed module 600; move to the vertical When the straight line segment is reached, the splint 304 is reset. At this time, the place where the belt is not rubbed is directly below the friction module 400. The cylinder 900 can drive the friction module 400 to move down again. During the downward movement, the moving block 302 moves toward the side of the belt roller 800 due to the action of the trapezoidal block 311 and the moving rod 310. The guide rod 305 moves along the oblique segment of the guide groove 306, driving the two sets of splints 304 to move toward the middle at the same time. When the friction head of the friction module 400 contacts the belt on the placement table 700, the guide rod 305 is at the intersection of the horizontal straight segment and the oblique segment of the guide groove 306, keeping the splint 304 clamping the belt.

[0029] In this state, the protrusion 308 in the slide bar 307 will pop out under the elastic force of the connecting spring 309 and be stuck in the inclined groove 312. The inner wall of the inclined groove 312 can limit the protrusion 308, and the inclined groove 312 is at the same height as the horizontal straight section of the guide groove 306, thereby limiting the movement state of the splint 304, so that it can maintain the state of clamping the belt and move, and the guide rod 305 is always in the horizontal straight section of the guide groove 306; the inner wall of the inclined groove 312 is provided with an inclined surface, and when the moving block 302 moves toward the side of the fixed module 600, the protrusion 308 moves along the inclined surface of the inner wall of the inclined groove 312, and is squeezed by the inclined surface and gradually moves into the slide bar 307, and loses contact with the inclined groove 312 After that, the restriction on the movement of the protrusion 308 and the clamping plate 304 is released, and the clamping plate 304 can be driven to move along the inner wall of the guide groove 306 by the guide rod 305. The setting of the slide bar 307 and the protrusion 308 is to ensure that when the friction module 400 moves up and drives the moving block 302 to move toward the side of the fixed module 600, the clamping plate 304 will not move up under the elastic force of the reset spring 303 and move along the inclined section of the guide groove 306, but will maintain the clamping state of the belt and move along the horizontal straight section of the guide groove 306. The setting of the inclined section of the guide groove 306 is to ensure that the clamping plate 304 does not contact the belt when it is reset, but clamps the belt after it is reset into place to avoid reverse conveying of the belt.

[0030] like Figures 2 to 5As shown, the moving rod 310 is slidably connected to the outer wall of the trapezoidal block 311, one end of the return spring 303 is fixedly connected to the outer wall of the splint 304, the other end of the return spring 303 is fixedly connected to the inner wall of the moving block 302, one end of the connecting spring 309 is fixedly connected to the outer wall of the protrusion 308, the other end of the connecting spring 309 is slidably connected to the inner wall of the slide rod 307, the slide rod 307 is fixedly connected to the outer wall of the splint 304, the slide rod 307 is slidably connected to the inner wall of the moving block 302, and the protrusion 308 contacts the inner wall of the inclined groove 312.

[0031] The above solution is adopted: the outer wall of the top end of the trapezoidal block 311 is fixedly connected to the outer wall of the bottom end of the slider 401 through the connecting rod. When the cylinder 900 drives the slider 401 to move up and down, the trapezoidal block 311 can be driven to move up and down synchronously; when the slider 401 moves, the friction module 400 can be driven to move up and down synchronously through the rotating block 402. When the friction module 400 is at the bottom to perform friction detection on the belt, the short side inclined surface of the trapezoidal block 311 contacts one end of the moving rod 310, and when the friction module 400 moves up, the inclined surface of the trapezoidal block 311 will squeeze the moving rod 310. 310 can only move laterally along the outer wall groove of the fixed block 301, thereby driving the moving block 302 to move laterally synchronously. At this time, the moving block 302 will move toward the side of the fixed module 600; and when the friction module 400 moves downward, the inclined surface will pull the moving rod 310, causing the moving rod 310 to move in the opposite direction along the inclined surface, and the moving block 302 moves toward the side of the belt roller 800, so that when the friction module 400 moves upward, the moving block 302 drives the splint 304 to clamp the belt and move, and when the friction module 400 moves downward, the moving block 302 and the splint 304 are reset to clamp the belt again.

[0032] like Figures 6 and 7 As shown, the driving mechanism includes a slider 401, the inner wall of the slider 401 is rotatably connected to a rotating block 402, the inner wall of the rotating block 402 is elastically connected to a rotating shaft 404 through a spiral spring 405, the outer wall of the rotating shaft 404 is fixedly connected to a rotating plate 403, the inner wall of the rotating block 402 is elastically connected to a limiting block 407 through a telescopic spring 406, and the inner wall of the fixed plate 200 is fixedly connected to a contact plate 408.

[0033] The above-mentioned scheme is adopted: the rotating block 402 is fixedly connected to the friction module 400 and passes through the outer wall of the fixed plate 200, and can move vertically on the outer wall of the fixed plate 200, and the cylinder 900 can drive the slider 401 to move vertically; there are multiple groups of rotating plates 403 on the outer wall of the rotating block 402, and the rotating plates 403 can be flipped with the rotating shaft 404 as the center, and the rotating plates 403 can only be flipped in one direction, and the other side is in contact with the inner wall of the rotating block 402 and cannot be flipped. When flipping, the rotating shaft 404 rotates synchronously, and the spiral spring 405 will be forced to shrink and rebound; there are multiple groups of horizontal baffles on the abutment plate 408, which can contact the outer wall of the rotating plate 403. When the slider 401 and the rotating block 402 move vertically, the rotating plate 403 contacts the multiple groups of baffles on the abutment plate 408 in turn.

[0034] like Figures 6 and 7 As shown, the slider 401 is slidably connected to the inner wall of the fixed plate 200, the slider 401 is fixedly connected to the movable end of the cylinder 900, one end of the spiral spring 405 is fixedly connected to the outer wall of the rotating shaft 404, the other end of the spiral spring 405 is fixedly connected to the inner wall of the rotating block 402, and the rotating shaft 404 is rotatably connected to the inner wall of the rotating block 402; one end of the telescopic spring 406 is fixedly connected to the outer wall of the limit block 407, the other end of the telescopic spring 406 is fixedly connected to the inner wall of the rotating block 402, the limit block 407 is slidably connected to the inner wall of the rotating block 402, and the limit block 407 is engaged with the groove on the inner wall of the slider 401.

[0035] The above scheme is adopted: the limit block 407 is hemispherical, and the inner wall circumference of the slider 401 is provided with four groups of limit grooves, and each group of the four limit grooves is opened at an interval of 90 degrees, corresponding to the positions of the four groups of friction heads. After each group of friction heads is switched, the limit block 407 will be engaged with different limit grooves, which can play a certain limiting effect, and the rotating block 402 and the slider 401 are kept fixed without being affected by external forces; when the movable end of the cylinder 900 drives the slider 401, the rotating block 402 and the friction module 400 to move downward, when the rotating block 402 moves downward, the rotating plate 403 is blocked by the outer wall of the top of the baffle on the abutment plate 408, and flips around the rotating shaft 404 as the center, so that the volute spring 405 is forced to contract. After the rotating block 402 moves down into place, the volute spring 405 is stretched due to the elastic force, and the rotating shaft 404 and the rotating plate 403 are reset, so that The rotating block 402 rotates during the downward movement; and when the rotating block 402 moves up, the rotating plate 403 contacts the outer wall of the bottom end of the baffle on the abutment plate 408, but because the rotating plate 403 cannot flip back, it is blocked by the baffle, causing the rotating block 402 to rotate, and multiple sets of rotating plates 403 contact the outer walls of multiple sets of baffles in turn, the principle is similar to that of a gear and a rack; during the rotation of the rotating block 402, the arc surface of the limit block 407 is squeezed by the inner wall of the limit groove and moves toward the inner wall of the rotating block 402. After the rotating block 402 moves up into place, it rotates just 90°, and the limit block 407 pops out and engages with another set of limit grooves, switching the other set of friction heads to relative and fixed positions with the placement table 700, so that when the friction module 400 moves up and down once, the friction heads are automatically switched, and the operator does not need to switch manually, which is more convenient.

[0036] like Figure 8 As shown, the chip removal mechanism 500 includes an air cylinder 501, the inner wall of the air cylinder 501 is elastically connected to the pressure plate 507 through a tension spring 508, the inner wall of the fixed plate 200 is rotatably connected to the rotating wheel 503, the outer wall of the rotating wheel 503 is wrapped with a pull rope 502, the outer wall of the air cylinder 501 is connected to the injection pipe 505 through the air supply pipe 504, and the inner wall of the air supply pipe 504 is provided with a valve 506.

[0037] The above solution is adopted: an air jet head is provided on the outer wall of the air jet tube 505, and the air jet head is directly opposite to the top position of the placement table 700. The surface of the belt will be worn during the friction detection process and a large amount of debris will be generated. The debris removal mechanism 500 can automatically blow air to the surface of the belt on the placement table 700 when the friction module 400 completes the friction and moves upward, so as to remove the debris attached to its surface, so as to prevent the debris from being in the position where the belt is to be rubbed and affecting the accuracy of the friction detection; when the friction module 400 is at the bottom for friction detection, the pull rope 502 is not affected by the tension and is in a relaxed state, and the pressure plate 507 is kept in a state above the inside of the air cylinder 501 due to the elastic force of the tension spring 508. There is gas inside the air cylinder 501, and the gas is blocked by the valve 506 and is sealed inside the air cylinder 501 when there is no pressure.

[0038] like Figure 8 As shown, the air cylinder 501 is fixedly connected to the inner wall of the fixed plate 200, one end of the tension spring 508 is fixedly connected to the outer wall of the pressure plate 507, the other end of the tension spring 508 is fixedly connected to the inner wall of the air cylinder 501, the two ends of the pull rope 502 are respectively fixedly connected to the outer walls of the pressure plate 507 and the slider 401, and the air injection tube 505 is fixedly connected to the outer wall of the fixed plate 200.

[0039] The above solution is adopted: when the friction module 400 completes the upward movement through friction, the slider 401 will pull one end of the pull rope 502 to move upward. When the pull rope 502 moves, it passes through two sets of rotating wheels 503. The rotating wheels 503 will rotate to reduce wear and change the pulling direction of the pull rope 502, so that the other end of the pull rope 502 pulls the pressure plate 507 to move downward. The tension spring 508 is stretched, and the pressure plate 507 squeezes the gas in the air cylinder 501, so that the gas pushes open the valve 506 under pressure and enters the air injection pipe 505 through the air supply pipe 504. Under the pressure of the continuous movement of the pressure plate 507, the gas is ejected from the nozzle of the air injection pipe 505. , blow away the debris on the surface of the belt, and the blowing direction is to blow toward the side of the fixed module 600, and the conveying mechanism 300 pulls the belt to pull the belt wrapped around the belt roller 800 to the placement table 700 for testing, so that the debris will not affect the friction detection; when the slider 401 moves down and resets, the pull rope 502 loses the pulling force of the slider 401, and the tension spring 508 drives the pressure plate 507 to reset, and the pressure plate 507 performs piston motion in the air cylinder 501 and inhales air into the air cylinder 501, and the valve 506 opens. When the pressure plate 507 is reset, the valve 506 closes again, sealing the gas in the air cylinder 501.

[0040] The working principle and use process of the present invention: The belt to be tested is wound around the belt roller 800, and one end of the belt is pulled out so that it passes through the surface of the placement table 700 and finally passes between the two sets of clamps 304 and is fixed in the upper and lower clamping blocks of the fixing module 600. The fixing module 600 drives the upper clamping block downward through the electric push rod, and applies high-pressure tightening force to one end of the belt to complete the fixation; at this time, the friction module 400 is at the top, the moving block 302 is in the initial position, and the clamping plate 304 has not yet clamped the belt.

[0041] During testing, the cylinder 900 starts, pushing the slider 401 downward, driving the friction module 400 to move downward synchronously. During the downward movement, the trapezoidal block 311 moves downward with the slider 401, and its inclined surface pulls the moving rod 310, causing the moving block 302 to move toward the side of the belt roller 800. The guide rod 305 slides along the inclined section of the guide groove 306, squeezing the two sets of splints 304 to move toward the middle, and the reset spring 303 is stretched; when the friction module 400 moves downward until the friction head contacts the belt surface, the splint 304 clamps the belt.

[0042] In this state, the protrusion 308 pops out under the action of the connecting spring 309 and is stuck in the inclined groove 312, limiting the clamping plate 304 so that it will not move due to the elastic force of the return spring 303, thereby maintaining the clamping state of the belt; the micro motor in the friction module 400 drives the current friction head to rotate and start friction detection.

[0043] After a single friction test is completed, the cylinder 900 drives the slider 401 to move upward, the friction module 400 detaches from the belt surface, the trapezoidal block 311 moves upward and squeezes the moving rod 310, driving the moving block 302 to move toward the side of the fixed module 600, and the guide rod 305 slides along the horizontal section of the guide groove 306. The protrusion 308 moves along the inner wall of the inclined groove 312, so that the splint 304 remains in a clamping state and pulls the belt to move, so that the belt is pulled out from the belt roller 800, and the un-frictioned part moves to the bottom of the friction head.

[0044] The rotating block 402 moves up synchronously with the slider 401, and the rotating plate 403 is blocked by the baffle of the abutment plate 408, driving the rotating block 402 to rotate 90°, and the limit block 407 is stuck in the next set of limit grooves, switching to the second set of friction heads; while the slider 401 moves up, the pull rope 502 is pulled, and the pull rope 502 drives the pressure plate 507 to move down, squeezing the gas in the air cylinder 501, and blowing air to the belt surface through the air jet pipe 505 to remove the debris generated by friction to prevent it from remaining on the belt surface and affecting subsequent friction.

[0045] After the slider 401 moves up to its position, the cylinder 900 drives it down again, repeating the above steps, the moving block 302 is reset, and the clamping plate 304 clamps the belt again; the switched friction heads contact the belt in turn to complete the wear resistance test under different roughness levels; each time the friction head is switched, the conveying mechanism 300 automatically pulls the belt so that the new test section is on the placement table 700, and the chip removal mechanism 500 automatically removes the debris, with a high degree of automation, reducing the process that the operator needs to intervene in during the friction process, saving manpower, and reducing the operator's work intensity.
