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.
[0023] Example: Reference Figure 1-4 The large-width road construction auxiliary device shown includes:
[0024] Reference components;
[0025] Detection assembly 1, which includes a fixed frame 8, an infrared rangefinder 7, a fixed cylinder 6, and a movable rod 5. The fixed frame 8 is connected to the reference assembly, and the reference assembly can maintain the fixed frame 8 at a constant height while being movable. A fixing hole is defined on the top outer wall of the fixed frame 8. The infrared rangefinder 7 is entirely fixed in the fixing hole. One end of the fixed cylinder 6 is fixed to the fixed frame 8. The infrared rangefinder 7 is located in the fixed cylinder 6. The fixed cylinder 6 is entirely sleeved on the movable rod 5.
[0026] The clamping assembly 3, one end of the moving rod 5 is connected to the clamping assembly 3;
[0027] From the above connection relationship, it can be seen that the moving rod 5 is on the bracket of the rearview mirror of the roller through the clamping component 3, and the reference component is placed on the road surface or roadbed that is not paved with asphalt, keeping the moving rod 5 perpendicular to the ground. When the roller is rolling, the roller moves up and down, and the infrared rangefinder 7 can measure the position change of the moving rod 5, so that the ground thickness can be quickly measured.
[0028] Specifically, the reference assembly includes a steel rope 4, two underground assemblies 2, and two sheaves 11. The two ends of the steel rope 4 are respectively connected to the two underground assemblies 2. A fixing plate 10 is fixed to the bottom of the fixing frame 8. One end of the axle of the sheave 11 is rotatably mounted on the fixing plate 10. The two sheaves 11 are arranged opposite to each other and are in contact with the steel rope 4.
[0029] It can be seen from the above connection relationship that the steel rope 4 remains perpendicular to the ground, and the fixing frame 8 moves on the steel rope 4 through the sheave 11.
[0030] Specifically, the underground assembly 2 includes a concave block 17, a rotating plate 16, a single-threaded rod 18, and an insertion tube 19. One end of the single-threaded rod 18 is rotatably mounted on the concave block 17, and the other end of the single-threaded rod 18 is threadedly mounted in the insertion tube 19. The rotating plate 16 is integrally rotatably mounted in the concave block 17, and one end of the steel rope 4 is fixed to the rotating plate 16.
[0031] It can be seen from the above connection relationship that the insertion tube 19 is inserted into the ground, and the single-threaded rod 18 is rotated to adjust the height so that the steel rope 4 is kept horizontal with the ground.
[0032] Specifically, the bottom end of the insertion tube 19 is conical.
[0033] Specifically, a speed sensor 9 is installed at the bottom of the fixed frame 8, and the speed measuring end of the speed sensor 9 is aligned with one of the groove wheels 11;
[0034] It can be seen from the above connection relationship that the speed sensor 9 can measure the moving speed of the groove wheel 11. Combined with the vibration frequency of the roller, the number of rollers per meter can be measured in combination with the speed.
[0035] Specifically, the clamping assembly 3 includes a cross bar 12, a double-threaded rod 14, two guide rods 13 and two clamping plates 15. One end of the cross bar 12 is fixed to the moving rod 5. A rotating hole is provided on the outer wall of the cross bar 12. The middle position of the double-threaded rod 14 is rotatably installed in the rotating hole. A guide hole is provided on the outer wall of the clamping plate 15. The guide rod 13 is slidably arranged in the guide hole. One end of the guide rod 13 is fixed to the cross bar 12. A left-handed screw hole and a right-handed screw hole are provided on the outer walls of the two clamping plates 15. The two ends of the double-threaded rod 14 are respectively installed in the left-handed screw hole and the right-handed screw hole through a left-handed thread and a right-handed thread.
[0036] As can be seen from the above connection relationship, by rotating the double-threaded rod 14 , the double-threaded rod 14 drives the two clamping plates 15 to move closer to each other through thread transmission until the bracket of the rearview mirror is clamped.
[0037] The working principle of the utility model is as follows: the moving rod 5 is on the bracket of the rearview mirror of the roller through the clamping component 3, that is, the double-threaded rod 14 is rotated, and the double-threaded rod 14 makes the two clamps 15 approach each other through threaded transmission until the bracket of the rearview mirror is clamped. The reference component is placed on a road surface or roadbed that is not paved with asphalt, that is, the insertion tube 19 is inserted into the ground, and the single-threaded rod 18 is rotated to adjust the height so that the steel rope 4 is kept horizontal with the ground and the moving rod 5 is kept vertical with the ground. When the roller is rolling, the roller moves up and down, and the steel rope 4 is kept vertical to the ground. The fixed frame 8 moves on the steel rope 4 through the groove pulley 11. The infrared rangefinder 7 can measure the position change of the moving rod 5, so that the ground thickness can be quickly measured. The speed sensor 9 can measure the moving speed of the groove pulley 11. Combined with the vibration frequency of the roller, the number of rolling times per meter can be measured in combination with the speed.
