Description

Technical Field

[0002] Highway pavement friction testing is an important task to ensure road safety, involving a variety of methods and standards. The pendulum friction coefficient tester is a dynamic pendulum instrument used to measure the pavement friction coefficient. The pendulum hammer of the pendulum tester is allowed to swing freely to drive the pointer to rotate and record the friction coefficient during the swing. After multiple swings, the average value of the friction coefficient recorded by the pointer is taken to obtain the result data.

[0003] When using a pendulum tester to test the friction coefficient of a road surface, it is necessary to first use a brush to clean the test ground, and in subsequent multiple tests, use a spray bottle or other equipment to spray water on the ground where the rubber block contacts, so that the ground is in a certain state of moisture.

The two ends of the coil spring 223 are respectively fixedly connected to one side of the outer surface of the rotating shaft 222 and one side of the inner wall of the rectangular plate 221. A blocking rod 224 is fixedly connected to the top of the inner wall of the water tank 217. A water pipe 225 is fixedly connected to one side of the outer surface of the tank box 21. The water pipe 225 is connected to the inside of the water tank 217. By setting the shaft 23, before using the detection device, the chalk can be inserted into the inside of the ring 24, and the bolt 25 is rotated to move on the inner wall of the ring 24 to make one end of the bolt 25 against one side of the chalk to clamp the chalk inside the ring 24. Then, water is added to the inside of the water tank 217 at the water pipe 225. When the base 1 is placed on the ground and ready for detection, the shaft 23 can be rotated clockwise.When the shaft 23 rotates clockwise, the surface of the second gear ring 211 located inside the annular groove 26 will contact the bottom end of the tooth block 226 at the top end of the inner wall of the circular groove 22. When the second gear ring 211 passes the tooth block 226, it will squeeze the tooth block 226 and compress the third spring 227 on the outer surface of the tooth block 226, so that the second gear ring 211 can rotate normally and pull the pull rope 213 to reel the pull rope 213 on its own surface. The pull rope 213 on one side of the second gear ring 211 pulls the piston block 214 located inside the air groove 216 to move in the direction of the pull rope 213 and compress the second spring 215. At the same time, when the shaft 23 rotates clockwise, the surface of the first gear ring 210 contacts the bottom end of the tooth block 226 at the top, and the tooth block 226 is stuck on the outer surface of the first gear ring 210. The two convex teeth prevent the first gear ring 210 from rotating clockwise with the shaft 23. The shaft 23 continues to be stressed, which will squeeze the top of the block 29 inside the annular groove 26, causing the block 29 to slide downward on the inner wall of the groove 27 and compress the first spring 28 until it is out of the groove 212 on the outer surface of the first gear ring 210. Then, the shaft 23 rotates clockwise to drive the second gear ring 211 to rotate along with it, and the first gear ring 210 cannot rotate along with it due to the obstruction of the top tooth block 226, so that the piston block 214 inside the air groove 216 will move with the pull rope 213, and the piston block 214 inside the water groove 217 will stop in place. After rotating the shaft 23 for several circles, the shaft 23 is released, and the second spring compressed on one side of the second gear ring 211 215 will push the piston block 214 to slide on the inner wall of the air groove 216, and pull the shaft rod 23 to rotate in the original direction through the pull rope 213 to release the pull rope 213 from the outer surface of the second gear ring 211, and the piston block 214 will quickly slide on the inner wall of the air groove 216 to spray out the air inside the air groove 216 through the air outlet 218 at the front end of the slot box 21, so as to clean the ground in front of the base 1 and blow away the pebbles and other debris on the ground in front of the base 1. The shaft rod 23 can be repeatedly rotated clockwise to perform jet cleaning. When the cleaning is completed and the inspection is performed, the shaft rod 23 is rotated counterclockwise. When the shaft rod 23 rotates counterclockwise, the tooth block 226 at the top of the second gear ring 211 will be stuck between the two convex teeth on the outer surface of the second gear ring 211 to prevent the second gear ring 211 from being moved. 11 rotates, and the shaft rod 23 continues to rotate, which makes the block 29 located in the groove 212 of the second gear ring 211 enter the groove 27 inside the ring groove 26. At the same time, when the shaft rod 23 rotates counterclockwise to make the groove 27 in the ring groove 26 below the first gear ring 210 coincide with the position of the groove 212 on the outer surface of the first gear ring 210, the block 29 located in the groove 27 will be pushed by the thrust of the first spring 28 to restore the original state and move the block 29 upward to be inserted into the groove 212 on the outer surface of the first gear ring 210. Then, the shaft rod 23 rotates counterclockwise to drive the first gear ring 210 to rotate counterclockwise and reel the pull rope 213 on one side of the first gear ring 210 onto its own surface, and pull the piston block 214 to slide on the inner wall of the water tank 217 through the pull rope 213.At the same time, the movement of the piston block 214 will drive the connecting rod 220 to pull the rectangular plate 221 to move in the direction of the piston block 214, so that the rectangular plate 221 is away from the water spray hole at one end of the inner wall of the water tank 217. The rectangular plate 221 continues to move for a distance and the top end will contact one side of the blocking rod 224 at the top of the inner wall of the water tank 217, so that the rectangular plate 221 rotates upward on the outer surface of the rotating shaft 222 and the coil springs 223 at both ends of the rotating shaft 222 are deformed. At this time, the water inside the water tank 217 between the rectangular plate 221 and the piston block 214 will flow through the The water in the water tank 217 is squeezed to the nozzle 219 by the second spring 215 on the outer surface of the piston block 214, and the connecting rod 220 pushes the rectangular plate 221 to move in the original direction. The coil springs 223 at both ends of the rotating shaft 222 are restored to their original state, which drives the rectangular plate 221 to rotate downward. Through the rapid movement of the piston block 214 and the rectangular plate 221, the water in the water tank 217 is squeezed to the nozzle 219. At the same time, the connecting rod 220 pushes the rectangular plate 221 to move in the original direction. The coil springs 223 at both ends of the rotating shaft 222 are restored to their original state, which drives the rectangular plate 221 to rotate downward. The downward swing of 21 squeezes the water inside the water tank 217 to the nozzle 219 and sprays it out to make the ground wet, and then a single test is performed. After the single test is completed, the shaft 23 is rotated counterclockwise to spray water to make the ground wet. When the shaft 23 is used, the chalk inside the ring 24 at one end of the shaft 23 is rotated to scratch on the road surface and mark on the ground to record the friction force detection position. By setting the convenient device 2, when the friction force of the road surface is tested, water is added to the inside of the water tank 217 at the water pipe 225, respectively. The shaft 23 is rotated clockwise and counterclockwise to drive the piston block 214 inside the air groove 216 and the water groove 217 to move. The shaft 23 is loosened to push the piston block 214 to move through the second spring 215 on one side of the piston block 214, so that the air groove 216 and the water groove 217 inside the tank box 21 respectively spray air to clean the ground or spray water to make the ground wet for easy detection. When using the convenient device 2, there is no need to carry additional cleaning tools and watering cans, and it is convenient to wet the road surface during the detection process, thereby improving the convenience of using the detection device;

[0041] See also Figures 2 to 12 The inner wall of the card slot 212 is semicircular, and the top edge of the card block 29 is arc-shaped. By setting the inner wall of the card slot 212 to be semicircular and the top edge of the card block 29 to be arc-shaped, when the first gear ring 210 or the second gear ring 211 cannot rotate with the shaft 23, the card block 29 is more likely to escape from the inside of the card slot 212 and enter the groove 27, so that the shaft 23 rotates normally. An observation hole 228 is opened on one side of the slot box 21. A transparent sheet of PC material is fixedly connected to the inner wall of the observation hole 228 away from the slot box 21. When using the convenient device 2, the water volume inside the slot box 21 can be observed through the PC transparent sheet on one side of the slot box 21 through the observation hole 228, so as to better judge whether the water inside the slot box 21 needs to be supplemented, thereby improving the convenience of using the convenient device 2.

[0042] See also Figures 4 to 12 The end of the shaft 23 away from the groove box 21 is fixedly connected to an operating block 229, and a plurality of protrusions are arranged on the outer surface of the operating block 229, and the protrusions are distributed in a circle on the outer surface of the operating block 229. Holding the protrusions on the outer surface of the operating block 229 can more conveniently rotate the operating block 229 to control the rotation of the shaft 23, further improving the convenience of the convenient device 2 when in use. A positioning ring 230 is fixedly connected to the side of the outer surface of the groove box 21 close to the shaft 23, and the outer surface part of the shaft 23 rotates on the inner wall of the positioning ring 230. When the shaft 23 is rotated, the end of the shaft 23 away from the circular groove 22 will rotate on the inner wall of the positioning ring 230, and the positioning ring 230 can limit the angles of the two ends of the shaft 23 to avoid holding it as much as possible. When the shaft rod 23 is rotated away from one end of the circular groove 22, the angles of the two ends of the shaft rod 23 are deflected. Two limit blocks 231 are fixedly connected to one side of the inner wall of the circular groove 22. The outer surface parts of the two pull ropes 213 are respectively located inside the two limit blocks 231. When the shaft rod 23 is rotated to control the first gear ring 210 or the second gear ring 211 to rotate and pull the pull rope 213, the outer surface parts of the two pull ropes 213 close to the first gear ring 210 or the second gear ring 211 will move inside the two limit blocks 231 respectively. The position of the pull rope 213 inside the circular groove 22 can be limited by the limit blocks 231 to avoid the pull rope 213 from being accidentally entangled in other positions inside the circular groove 22 as much as possible, affecting the normal use of the convenient device 2.

[0046] Instructions for use: When using the present application, a certain amount of water can be first added to the inside of the water bottle 34 at the top of the water bottle 34, and then the sealing plug 35 can be inserted into the water injection hole at the top of the water bottle 34 to seal the water bottle 34, and then the threaded tube 36 at the bottom of the water bottle 34 can be inserted into the inner wall of the round tube 31, and the water bottle 34 can be rotated so that the outer surface of the threaded tube 36 is threadedly connected with the inner wall of the round tube 31. When the threaded tube 36 enters the inside of the round tube 31, the top rod 33 at the top of the frame rod 32 will contact the round rod 310 inside the through hole 312. As the threaded tube 36 continues to penetrate into the top rod 33, the round rod 310 and the round block 39 will be pushed upward and the fourth spring 38 will be compressed, so that the round block 39 is away from the bottom of the inner wall of the water bottle 34. At this time, the water inside the water bottle 34 can enter the through hole 3 through the bottom of the round block 39. 12, and enter the inside of the circular tube 31 through the through hole 312 and the two sides of the rack 32, and then enter the inside of the water tank 217 through the water pipe 225, and observe the water volume inside the tank box 21 through the observation hole 228 at the PC transparent sheet on one side of the tank box 21, then carry the detection device to the detection road surface, place the base 1 on the ground, observe the position of the bubble in the horizontal bubble on the surface of the base 1, rotate the support legs 4 at the left and right ends and the rear of the base 1 respectively, so that the support legs 4 move up and down on the inner wall of the base 1 to adjust the support height of the support legs 4 to the base 1 until the base 1 remains horizontal, then push the pendulum rod 9 to swing and observe whether the rubber block 11 at the bottom of the pendulum 10 can touch the ground, rotate the adjustment bolts on both sides of the sleeve rod 8, pull the sleeve rod 8 to move up and down on the outer surface of the support rod 5 to adjust the sleeve rod 8 and the height position of the pendulum 10 until the rubber block 11 at the bottom end can contact the ground when the pendulum 10 moves to the bottom. Then, rotate the adjusting bolts on both sides of the sleeve rod 8 to fix the position of the sleeve rod 8 and the support rod 5, pull the spring pin on one side of the positioning block 12, push the pendulum rod 9 to rotate and clamp the outer surface of the pendulum rod 9 inside the positioning block 12, loosen the spring pin to fix the pendulum rod 9 in the positioning block 12, and push the recording rod 7 to move to the inside of the pendulum rod 9, insert the chalk into the inside of the ring 24, turn the bolt 25 to move on the inner wall of the ring 24, and push one end of the bolt 25 against one side of the chalk to clamp the chalk inside the ring 24, then add water to the inside of the water tank 217 at the water pipe 225. After placing the base 1 on the ground and preparing for testing, you can rotate the shaft 23 in the clockwise direction. When the rod 23 rotates clockwise, the surface of the second gear ring 211 located inside the annular groove 26 will contact the bottom end of the tooth block 226 at the top end of the inner wall of the circular groove 22. When the second gear ring 211 passes the tooth block 226, it will squeeze the tooth block 226 and compress the third spring 227 on the outer surface of the tooth block 226, so that the second gear ring 211 can rotate normally and pull the pull rope 213 to reel the pull rope 213 on its own surface. The pull rope 213 on one side of the second gear ring 211 pulls the piston block 214 located inside the air groove 216 to move in the direction of the pull rope 213 and compress the second spring 215. At the same time, when the shaft rod 23 rotates clockwise, the surface of the first gear ring 210 contacts the bottom end of the tooth block 226 at the top, and the tooth block 226 is stuck between the two convex teeth on the outer surface of the first gear ring 210.The first gear ring 210 cannot rotate clockwise with the shaft 23. The shaft 23 continues to be stressed, which squeezes the top of the block 29 inside the annular groove 26, causing the block 29 to slide downward on the inner wall of the groove 27 and compress the first spring 28 until it is out of the groove 212 on the outer surface of the first gear ring 210. Then, the shaft 23 rotates clockwise to drive the second gear ring 211 to rotate along with it. The first gear ring 210 cannot rotate along with it due to the obstruction of the top tooth block 226. The piston block 214 located in the air groove 216 moves with the pull rope 213, and the piston block 214 located in the water groove 217 stops in place. After rotating the shaft 23 for several circles, the shaft 23 is released, and the second spring 215 compressed on one side of the second gear ring 211 pushes the piston block 214 to move along with the pull rope 213. The piston block 214 slides on the inner wall of the air groove 216, and the shaft rod 23 is pulled to rotate in the original direction through the pull rope 213 to release the pull rope 213 from the outer surface of the second gear ring 211. The piston block 214 quickly slides on the inner wall of the air groove 216 to spray out the air inside the air groove 216 through the air outlet 218 at the front end of the groove box 21, so as to clean the ground in front of the base 1 and blow away the pebbles and other debris on the ground in front of the base 1. The shaft rod 23 can be repeatedly rotated clockwise for jet cleaning. When the cleaning is completed and the inspection is performed, the shaft rod 23 is rotated counterclockwise. When the shaft rod 23 rotates counterclockwise, the tooth block 226 at the top of the second gear ring 211 will be stuck between the two convex teeth on the outer surface of the second gear ring 211 to prevent the second gear ring 211 from rotating, and the shaft rod 23 The rod 23 continues to rotate so that the block 29 located inside the groove 212 of the second gear ring 211 enters the groove 27 inside the ring groove 26. At the same time, the shaft rod 23 rotates counterclockwise so that the groove 27 in the ring groove 26 below the first gear ring 210 coincides with the groove 212 on the outer surface of the first gear ring 210. The block 29 located inside the groove 27 will be pushed upward and inserted into the groove 212 on the outer surface of the first gear ring 210 due to the thrust of the first spring 28 to restore the original state. Then, the shaft rod 23 rotates counterclockwise to drive the first gear ring 210 to rotate counterclockwise and reel the pull rope 213 on one side of the first gear ring 210 onto its own surface, and pull the piston block 214 to slide on the inner wall of the water tank 217 through the pull rope 213. At the same time, the piston block 214 The movement will drive the connecting rod 220 to pull the rectangular plate 221 to move in the direction of the piston block 214, so that the rectangular plate 221 is away from the water spray hole at one end of the inner wall of the water tank 217. The rectangular plate 221 continues to move for a distance and the top end will contact the side of the blocking rod 224 at the top of the inner wall of the water tank 217, so that the rectangular plate 221 rotates upward on the outer surface of the rotating shaft 222 and the coil springs 223 at both ends of the rotating shaft 222 are deformed. At this time, the water inside the water tank 217 between the rectangular plate 221 and the piston block 214 will pass between the rectangular plate 221 and the bottom end of the inner wall of the water tank 217 and enter the front of the rectangular plate 221. The rotating shaft 222 is released and the second spring 215 on the outer surface of the piston block 214 restores the original state and pushes the piston block 214 to slide in the direction of the nozzle 219.The water inside the water tank 217 is squeezed to the nozzle 219, and at the same time, the connecting rod 220 will push the rectangular plate 221 to move in the original direction. The coil springs 223 at both ends of the rotating shaft 222 will return to their original state and drive the rectangular plate 221 to rotate downward. Through the rapid movement of the piston block 214 and the downward swing of the rectangular plate 221, the water inside the water tank 217 is squeezed to the nozzle 219 and sprayed out to make the ground wet. Then, the spring pin on one side of the positioning block 12 is pulled to make the pendulum 10 swing freely. The recording rod 7 is pushed by the pendulum rod 9 to move to the scale plate 6 to point to the data on the surface of the scale plate 6. When the pendulum rod 9 swings back, the pendulum rod 9 is controlled by hand to record the data pointed by the recording rod 7 for a single After a single test is completed, when the water in the water tank 217 is output, the water level in the water pipe 225 and the round tube 31 will drop. At the same time, the water in the water bottle 34 will continue to enter the round tube 31 through the through hole 312 and the two sides of the rack 32 to replenish the water in the water tank 217. The water in the water tank 217 is automatically added with water. Then, the shaft 23 is rotated counterclockwise to spray water to make the ground wet, so that the recording rod 7 and the pendulum 10 are reset to perform multiple tests and record data. When the shaft 23 is used, the chalk inside the ring 24 at one end of the shaft 23 will be scratched on the road surface and marked on the ground to record the friction force detection position.
