[0002] The steel wheel of a road roller is an important working component, and its roundness directly affects the quality and efficiency of road rolling operations.

[0003] Existing methods for testing the roundness of the cross section of the steel wheel of a road roller mainly rely on manual visual inspection or measurement using a measuring tape. However, manual visual inspection mainly relies on subjective observation and is easily affected by factors such as light, angle, and operator experience, making it difficult to guarantee the accuracy of the test results. Measuring tape requires the operator to take multiple measurements at different positions to obtain multiple data points and perform complex calculations to obtain the results, which is cumbersome and inefficient.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4This utility model provides a testing device for steel wheels of a road roller, including a base plate 1. A second support frame 10 is bolted to the top of the base plate 1. Two sliding rods 8 are slidably connected to one side of the second support frame 10. A baffle 9 is bolted to the other end of the two sliding rods 8. A stop block 11 is bolted to the other end of each of the two guide rods 14. The baffle 9 can limit the sliding rods 8, and the stop block 11 can limit the guide rods 14. A fixing plate 7 is bolted to one end of the two sliding rods 8. Two guide rods 14 are slidably connected to one side of the fixing plate 7. A fixing frame 6 is bolted to one end of each guide rod 14. Two connecting frames 1 are bolted to the bottom of the fixing frame 6. 2. Spotlights 15 are bolted to one side of the two connecting frames 12. When the spotlights 15 are turned on, they illuminate the contact point between the pressure roller 5 and the steel wheel. When there is a depression on the surface of the steel wheel, a gap will appear at the contact point between the pressure roller 5 and the steel wheel, and the light will pass through these gaps, thus quickly detecting the depression on the surface of the steel wheel. The pressure roller 5 is rotatably connected between the inner walls of the two sides of the fixing frame 6. Springs 13 are sleeved on the outer circumference of the two guide rods 14, and the two ends of the springs 13 are fixed to the fixing frame 6 and the fixing plate 7 respectively. A sliding plate 17 is bolted to one side of the fixing frame 6, and the sliding plate 17 is slidably connected to the fixing plate 7. Multiple scale lines 16 are evenly opened on the top of the sliding plate 17. The top of the base plate 1... The unit is equipped with a transmission mechanism that drives the steel wheel to rotate. The transmission mechanism consists of two first support frames 2, which are bolted to the top of the base plate 1. Two rotating shafts 4 are rotatably connected between the two first support frames 2. Two rollers 3 are welded to the outer circumference of each of the two rotating shafts 4. A DC motor is bolted to one side of one of the first support frames 2, and the output shaft of the DC motor is fixed to one of the rotating shafts 4. When the DC motor is started, the output shaft of the DC motor drives one of the rotating shafts 4 to rotate, which in turn drives the rollers 3 to rotate, and the rollers 3 drive the steel wheel to rotate. This achieves the rotation of the steel wheel, greatly facilitating the measurement of the roundness of the side cross section of the steel wheel. The second support frame 10... A fixing mechanism is provided on one side to limit the movement of two sliding rods 8. Pushing the two sliding rods 8 causes the fixing plate 7 to move. The fixing plate 7 causes the guide rod 14, the fixing frame 6, and the pressure roller 5 to move, so that the pressure roller 5 contacts the steel wheel placed on the transmission mechanism. Then the transmission mechanism is started, and the transmission mechanism drives the steel wheel to rotate. When the side cross section of the steel wheel is not round, the steel wheel will squeeze the pressure roller 5 to move backward. The pressure roller 5 drives the fixing frame 6 and the slide plate 17 to move backward. The deviation of the side cross section of the steel wheel can be judged by the scale line 16 on the top of the slide plate 17. Thus, the roundness of the side cross section of the steel wheel can be measured, which greatly improves the accuracy of the measurement of the roundness of the side cross section of the steel wheel. Moreover, the operation is simple and efficient.

[0024] In this invention, the fixing mechanism is a protrusion 20, which is fixed to one side of the second support frame 10 by bolts. A threaded rod 21 is threadedly connected to the bottom of the protrusion 20, and a knob is fixed to the other end of the threaded rod 21 by bolts. Multiple anti-slip grooves are evenly distributed on the outer circumference of the knob, allowing for easier rotation of the threaded rod 21. One end of the threaded rod 21 passes through the protrusion 20 and is rotatably connected to a top block 18. Two anti-slip pads are adhered to the top of the top block 18, and the anti-slip pads greatly increase the slip resistance between the slide rod 8 and the top block 18 at their contact points. The friction between blocks 18 is used to fix two positioning pins 19 at the bottom of the top block 18 by bolts. The positioning pins 19 are slidably connected to the protrusion 20. The positioning pins 19 make the top block 18 slide more smoothly. The top block 18 is slidably connected to one side of the second support frame 10. By rotating the threaded rod 21 clockwise, the threaded rod 21 drives the top block 18 to move upward, so that the top block 18 contacts the slide rod 8. The friction between the top block 18 and the slide rod 8 quickly fixes the slide rod 8, thereby fixing the position of the fixing plate 7 and the pressure roller 5.

[0025] The working principle of this utility model is as follows: A steel wheel is placed on multiple rollers 3, and then two sliding rods 8 are pushed. The two sliding rods 8 drive the fixed plate 7 to move. The fixed plate 7 drives the guide rod 14, the fixed frame 6, and the pressure roller 5 to move, so that the pressure roller 5 contacts the steel wheel placed on the transmission mechanism. Then, the threaded rod 21 is rotated clockwise, and the threaded rod 21 drives the top block 18 to move upward, so that the top block 18 contacts the sliding rod 8. The friction between the top block 18 and the sliding rod 8 quickly fixes the sliding rod 8. Then, the DC motor is started, and the output shaft of the DC motor drives one of the rotating shafts 4 to rotate. The rotating shaft 4 drives the roller 3 to rotate, and the roller 3 drives the steel wheel to rotate. When the side cross section of the steel wheel is not round, the steel wheel will squeeze the pressure roller 5 to move backward. The pressure roller 5 drives the fixed frame 6 and the sliding plate 17 to move backward. The deviation of the side cross section of the steel wheel can be judged by the scale line 16 on the top of the sliding plate 17.
