Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hemp rope detection, in particular to a sisal rope strength online detection device. BACKGROUND

[0002] Sisal rope is a kind of natural fiber rope, which is widely used in shipbuilding, fishing, construction and industrial binding due to its high strength, corrosion resistance and good friction resistance. The rope needs to bear complex mechanical action in actual use, especially the tensile strength and friction resistance, which are directly related to the safety and service life. Therefore, it is very important to accurately detect the strength and wear resistance of sisal rope during production. At present, the strength detection of sisal rope is mostly carried out in an offline manner, that is, the sample is taken from the production line and sent to the laboratory equipment for tensile and friction test. This method has the following disadvantages: first, the detection period is long, which cannot feedback the production quality in real time, resulting in late problem discovery; second, sampling detection cannot cover all products, which has the risk of missing detection; third, the traditional detection equipment has complex structure and cumbersome operation, and the efficiency is low, which is difficult to meet the needs of modern continuous production. In the prior art, although there are some online detection devices for ropes, they are single in function and mainly focus on the detection of tensile or wear resistance, lacking integrated comprehensive testing means. In addition, these devices lack coordination in clamping, traction, release and continuous feeding, which easily causes unstable detection process or damage to the sample, affecting the accuracy of the results. Therefore, there is an urgent need for a detection device that can realize synchronous online detection of sisal rope tensile and wear resistance, has reasonable structure and high automation, so as to improve production quality and product reliability.

[0035] As shown in the drawings, Figures 4-7 As shown, the pulling module further comprises a pulling rod 223 rotatably installed on the traversing rod 112, a lifting sleeve 219 is rotatably installed on the pulling rod 223, the lifting sleeve 219 is slidingly installed with the detection frame 103, a fixed trapezoidal block 222 is fixedly installed on the detection frame 103, two slope surfaces are arranged on the fixed trapezoidal block 222, a hook rod 220 is slidingly installed in the lifting sleeve 219, an inner spring 221 is arranged between the hook rod 220 and the lifting sleeve 219, two inclines are arranged on the hook rod 220, an outer side block 218 is fixedly installed on the lifting frame 212, and an incline is arranged on the outer side block 218.

[0036] In use, the sisal rope is passed through the two lifting frames 212, located between the fixed clamping block 217 and the movable clamping block 216, then passed through the rope inlet pipe 301, and passed through between the plurality of upper conveying rollers 303 and the lower conveying rollers 306, and passed through between the upper friction rollers 310 and the lower friction rollers 314. The upper gear 115 drives the worm gear 202 and the worm 201 to rotate through the transmission belt 203, the worm 201 drives the worm wheel 208 to rotate, the worm wheel 208 drives the inner sliding column 207 and the bidirectional screw rod 209 to rotate, the inner convex ball 210 and the bidirectional screw rod 209 are matched to drive the lifting inclined block 211 to descend, the lifting inclined block 211 descends to push the movable clamping block 216 to move towards the fixed clamping block 217 through the incline, and the spring between the movable clamping block 216 and the lifting frame 212 is stretched. At this time, the sisal rope is clamped through the rope clamping grooves of the movable clamping block 216 and the fixed clamping block 217.

[0037] Subsequently, the toothed gear 109 disengages from the intermittent gear 113. At this point, the movable clamping block 216 and the fixed clamping block 217 maintain the clamping of the sisal rope. Then, the lateral moving rod 112 moves outward, driving the upper lifting sleeve 219 downward via the pull rod 223, while the lower lifting sleeve 219 moves upward. When the upper lifting sleeve 219 moves downward, it drives the upper outer block 218 and the lifting frame 212 to descend via the hook rod 220. The lifting frame 212 drives the upper end of the sisal rope downward via the movable clamping block 216 and the fixed clamping block 217, while the lower lifting frame 212 rises, driving the sisal rope downward via the movable clamping block 216 and the fixed clamping block 217. The lower end of the hemp rope moves upward, the detection spring 215 is compressed, the inner sliding column 207 slides downward relative to the worm gear 208, and when the slope of the lower end of the hook rod 220 contacts the fixed trapezoidal block 222, the fixed trapezoidal block 222 drives the hook rod 220 to move to the right in the lifting sleeve 219 through the slope, the inner spring 221 is compressed, causing the hook rod 220 to disengage from the outer block 218, and then the detection spring 215 rebounds, causing the upper lifting frame 212 to pop upward with the upper end of the sisal rope, and causing the lower lifting frame 212 to pop downward with the lower end of the sisal rope, and the tensile strength test of the sisal rope is performed, and the buffer spring 214 buffers the lifting frame 212.

[0038] Subsequently, the missing tooth gear 109 and the intermittent gear 113 mesh again. Since the bidirectional lead screw 209 has a bidirectional external thread, it continues to rotate, causing the lifting inclined block 211 to rise. The spring between the movable clamping block 216 and the lifting frame 212 resets, moving the movable clamping block 216 away from the fixed clamping block 217. The lateral rod 112 begins to move inward, driving the upper lifting sleeve 219 and hook rod 220 upward via the pull rod 223, while the lower lifting sleeve 219 and hook rod 220 move downward. When the hook rod 220 contacts the outer block 218, the hook... After the inclined surface of the rod 220 contacts the inclined surface of the outer block 218, the outer block 218 causes the hook rod 220 to slide to the left within the lifting sleeve 219, and the inner spring 221 is compressed. When the inclined section of the hook rod 220 passes the outer block 218, the inner spring 221 rebounds, causing the hook rod 220 to hook the outer block 218 again, returning to the initial state. At this time, the half gear 105 disengages from the output gear 106, and the half gear 105 meshes with the lower mating gear 302. The anti-wear mechanism conveys the sisal rope backward for a section, and then performs a tensile test on the next section of the sisal rope, repeating this process.

[0039] like Figure 8As shown, the anti-wear mechanism includes multiple rope inlet tubes 301 fixedly installed inside the base box 101. An upper friction roller 310 and a lower friction roller 314 are rotatably installed inside the base box 101. An upper friction gear 311 is fixedly installed on the upper friction roller 310, and a lower friction gear 315 is fixedly installed on the lower friction roller 314. The upper friction gear 311 meshes with the lower friction gear 315. An upper friction wheel 312 is fixedly installed on the upper friction roller 310, and a lower friction wheel 313 is rotatably installed inside the base box 101. The upper friction wheel 312 cooperates with the lower friction wheel 313.

[0040] like Figure 8 As shown, the bottom box 101 is equipped with three sets of conveying modules. Each conveying module includes an upper conveying roller 303 rotatably mounted inside the bottom box 101, an upper conveying gear 305 fixedly mounted on the upper conveying roller 303, a lower conveying roller 306 rotatably mounted inside the bottom box 101, a lower conveying gear 307 and a conveying drive wheel 308 fixedly mounted on the lower conveying roller 306, the upper conveying gear 305 meshing with the lower conveying gear 307, a conveyor belt 309 wrapped around the three conveying drive wheels 308, a conveying gear 304 fixedly mounted on the upper conveying roller 303 in the middle, the conveying gear 304 meshing with the lower docking gear 302, and the conveyor belt 309 cooperating with the lower friction wheel 313.

[0041] The lower connecting gear 302 drives the conveying gear 304 to rotate, which in turn drives the upper conveying roller 303 and the upper conveying gear 305 to rotate, which in turn drives the lower conveying roller 306, the lower conveying gear 307, and the conveying drive wheel 308 to rotate. The upper conveying roller 303 and the lower conveying roller 306 rotate in opposite directions. The three conveying modules rotate synchronously through the conveyor belt 309. The sisal rope is conveyed through the upper conveying roller 303 and the lower conveying roller 306. The conveyor belt 309 drives the lower friction wheel 313 to rotate through friction transmission, which in turn drives the upper friction wheel 312, the upper friction gear 311, and the upper friction roller 310 to rotate. The upper friction gear 311 drives the lower friction gear 315 and the lower friction roller 314 to rotate. The upper friction roller 310 rotates in the opposite direction to the upper conveying roller 303, and the lower friction roller 314 rotates in the opposite direction to the lower conveying roller 306. The upper friction roller 310 and the lower friction roller 314 are used to perform abrasion resistance testing on the sisal rope.

[0042] The working principle of the online sisal rope strength testing device disclosed in this invention is as follows: During use, the sisal rope passes through two lifting frames 212, positioned between the fixed clamping block 217 and the movable clamping block 216, then through the rope inlet tube 301, and between multiple upper conveying rollers 303 and lower conveying rollers 306, and between the upper friction roller 310 and lower friction roller 314. The motor 104 drives the half-tooth gear 105 to rotate. The half-tooth gear 105 drives the lower engaging gear 302 and the output gear 106 to rotate intermittently. When the half-tooth gear 105 meshes with the lower engaging gear 302, the half-tooth gear 105 and the output gear... When gear 106 disengages, and when half gear 105 meshes with output gear 106, half gear 105 disengages from lower mating gear 302. Output gear 106 drives crank 108 to rotate via vertical transmission belt 107. As crank 108 rotates, it slides in the long groove of slide bar 111 via inner connecting column 110, causing slide bar 111 and transverse rod 112 to slide back and forth along upper frame 102 in the horizontal direction. Crank 108 drives intermittent gear 113 to rotate intermittently via toothed gear 109. Intermittent gear 113 drives upper gear 115 to rotate via oblique transmission belt 114.

[0043] The upper gear 115 drives the worm gear 202 and worm 201 to rotate via the transmission belt 203. The worm 201 drives the worm wheel 208 to rotate, and the worm wheel 208 drives the inner sliding column 207 and the double-acting lead screw 209 to rotate. Through the cooperation of the inner convex ball 210 and the double-acting lead screw 209, the lifting inclined block 211 is driven to descend. The descending lifting inclined block 211 pushes the movable clamping block 216 towards the fixed clamping block 217. The spring between the movable clamping block 216 and the lifting frame 212 is stretched. At this time, the sisal rope is clamped through the rope-clamping grooves of the movable clamping block 216 and the fixed clamping block 217. Then, the toothed gear 109 disengages from the intermittent gear 113. At this time, the movable clamping block 216 and the fixed clamping block 217 keep clamping the sisal rope. Then, the lateral rod 112 moves outward. The lateral rod 112 moves outward via the pull rod 223. The upper lifting sleeve 219 moves downward and the lower lifting sleeve 219 moves upward. When the upper lifting sleeve 219 moves downward, the hook rod 220 drives the upper outer block 218 and the lifting frame 212 to descend. The lifting frame 212 drives the upper end of the sisal rope to move downward through the movable clamping block 216 and the fixed clamping block 217. The lower lifting frame 212 rises and drives the lower end of the sisal rope to move upward through the movable clamping block 216 and the fixed clamping block 217. The detection spring 215 is compressed, and the inner sliding column 207 slides downward relative to the worm gear 208. When the slope at the lower end of the hook rod 220 contacts the fixed trapezoidal block 222, the fixed trapezoidal block 222 drives the hook rod 220 to move to the right inside the lifting sleeve 219 through the slope. The inner spring 221 is compressed, causing the hook rod 220 to disengage from the outer block 218.

[0044] Then, the spring 215 is tested for rebound, causing the upper lifting frame 212, carrying the upper end of the sisal rope, to spring upwards, and the lower lifting frame 212, carrying the lower end of the sisal rope, to spring downwards. A tensile strength test is performed on the sisal rope. The buffer spring 214 buffers the lifting frame 212. Then, the toothed gear 109 and the intermittent gear 113 mesh again. Because the bidirectional lead screw 209 has a bidirectional external thread, it continues to rotate, causing the lifting inclined block 211 to rise. The spring between the movable clamping block 216 and the lifting frame 212 resets, causing the movable clamping block 216 to move away from the fixed position. The fixed clamping block 217 and the transverse moving rod 112 begin to move inward, driving the upper lifting sleeve 219 and hook rod 220 to move upward via the pull rod 223, while the lower lifting sleeve 219 and hook rod 220 move downward. When the hook rod 220 contacts the outer block 218, the outer block 218 causes the hook rod 220 to slide to the left within the lifting sleeve 219, compressing the inner spring 221. When the inclined section of the hook rod 220 passes the outer block 218, the inner spring 221 rebounds, causing the hook rod 220 to hook the outer block 218 again.

[0045] At this point, the system returns to its initial state. The half-gear 105 disengages from the output gear 106 and engages with the lower connecting gear 302. The lower connecting gear 302 drives the conveying gear 304 to rotate. The conveying gear 304 drives the upper conveying roller 303 and the upper conveying gear 305 to rotate, which in turn drives the lower conveying roller 306, the lower conveying gear 307, and the conveyor drive wheel 308 to rotate. The upper conveying roller 303 rotates in the opposite direction to the lower conveying roller 306. The conveyor belt 309 causes the three sets of conveying modules to rotate synchronously. The upper conveyor... Roller 303 and lower conveyor roller 306 transport the sisal rope. Conveyor belt 309 drives lower friction wheel 313 to rotate via friction drive, which in turn drives upper friction wheel 312, upper friction gear 311, and upper friction roller 310 to rotate. Upper friction gear 311 drives lower friction gear 315 and lower friction roller 314 to rotate. The rotation direction of upper friction roller 310 is opposite to that of upper conveyor roller 303, and the rotation direction of lower friction roller 314 is opposite to that of lower conveyor roller 306. The upper friction roller 310 and lower friction roller 314 are used to perform abrasion resistance testing on the sisal rope. Subsequently, tensile strength and abrasion resistance testing are performed on the next section of sisal rope, and this process is repeated.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
