The transverse guide rail is arranged on the detection surface, the base slides along the transverse guide rail, the bracket is arranged on the base, the rotating wheel, the hydraulic motor and the hydraulic cylinder are all arranged on the base, the hydraulic motor drives the rotating wheel to rotate, the rotating wheel abuts against the detection surface to rotate and drives the base to slide along the transverse guide rail, and the hydraulic cylinder is used to drive the rotating wheel to rise and fall.

[0004] When the rotating wheel in the above patent tests the wear resistance of the test surface, the frictional resistance of the rotating wheel on the sample may cause the test sample to shift or move laterally, thereby causing the test sample to shift and separate from the rotating wheel, affecting the test data of the wear resistance of the test sample. Therefore, there is still room for improvement. Utility Model Content

The transverse guide rail 13 is placed on the testing surface. There are two transverse guide rails 13. The base 11 is in the shape of a rectangular plate. The two transverse guide rails 13 are respectively located at both ends of the base 11. Circular plates 113 are fixed at both ends of the base 11 along the length direction, and the circular plates 113 are stuck in the transverse guide rails 13, so that the base 11 slides along the transverse guide rails 13. The bracket 12 is fixed on the base 11, the hydraulic motor 15 is fixed on the base 11, the hydraulic cylinder 16 is fixed on the bracket 12, and the rotating wheel 14 is fixed on the output rod of the hydraulic cylinder 16, so that the hydraulic cylinder 16 drives the rotating wheel 14 to rise and fall. The base 11 is provided with a through hole 111 for the rotating wheel 14 to penetrate, so that the rotating wheel 14 abuts against the testing surface through the through hole 111. The output shaft of the hydraulic motor 15 is also sleeved with a synchronous belt 151, and the hydraulic motor 15 drives the rotating wheel 14 to rotate through the synchronous belt 151, so that when the rotating contact detection surface rotates, the base 11 is driven to slide along the transverse track. The base 11 is also provided with a plurality of positioning mechanisms, which are distributed at the front and rear ends of the base 11. The positioning mechanisms are used to temporarily contact the detection surface, thereby improving the stability of the base 11 when the rotating wheel 14 abuts the detection surface and rotates.

[0034] Reference Figure 1 , Figure 2 as well as Figure 4 The top of the base 11 is recessed with a moving groove 112. There are two moving grooves 112. The two moving grooves 112 are respectively located on both sides of the base 11 along the width direction. The moving groove 112 is in the shape of a rectangular groove. The length direction of the moving groove 112 is consistent with the length direction of the base 11. The side walls of the moving groove 112 on both sides along the width direction are recessed with limiting grooves (not shown in the figure). The limiting grooves are in the shape of a rectangular groove. The limiting grooves are located at the bottom of the moving groove 112, and the side walls of the limiting grooves at both ends along the length direction are flush with the side walls of the moving groove 112 at both ends along the length direction.

[0036] Reference Figure 1 as well as Figure 2 The movable seat 2 is threadedly connected with a limiting bolt 21, and the axis of the limiting bolt 21 is perpendicular to the plane of the base 11, so that the limiting bolt 21 is screwed toward the base 11 until it is tightly pressed against the upper surface of the base 11. The limiting bolt 21 temporarily fixes the relative position of the movable seat 2 and the base 11 to prevent the movable seat 2 from sliding relative to the base 11 during the rotation of the rotating wheel 14.

[0037] Reference Figure 1 as well as Figure 2 The base 11 is also provided with a moving part for driving the positioning mechanism to move. In this embodiment, the moving part includes a moving cylinder 3. There are four moving cylinders 3. The four moving cylinders 3 are respectively fixed to one end of the moving base 2 outside the moving groove 112, so that when the moving base 2 moves, the moving cylinder 3 is driven to move; the output shafts of the moving cylinders 3 located on the same side of the base 11 are arranged back to back.

The four lifting cylinders 4 are respectively inserted into four positioning sleeves 31. The output shaft of the lifting cylinder 4 faces the bottom of the base 11, so that the positioning sleeve 31 is sleeved on the lifting cylinder 4, so that the lifting cylinder 4 can be lifted and lowered relative to the movable cylinder 3, and the relative position of the lifting cylinder 4 and the positioning sleeve 31 can be fixed by screwing the positioning bolt 32 into the lifting cylinder 4 until it is tight against the lifting cylinder 4.

[0040] Reference Figure 1 as well as Figure 2 The output shaft of the lifting cylinder 4 is also fixed with a positioning plate 41, and the positioning plate 41 is driven by the lifting cylinder 4 to descend to the abutment detection surface, thereby improving the stability of the base 11 sliding relative to the transverse guide rail 13 when the rotating wheel 14 rotates.

[0041] The implementation principle of the wear tester for convenient highway testing in the embodiment of the present application is as follows:

[0042] When the test surface needs to be tested for wear resistance, first place the wear tester on the test surface, then adjust the movable seat 2 and the movable cylinder 3 until the lifting cylinder 4 is in the appropriate position, and then fix the movable seat 2 with the limiting bolt 21; then adjust the positioning plate 41 to abut the test surface through the lifting cylinder 4, and then start the hydraulic cylinder 16 to drive the rotating wheel 14 to descend until the rotating wheel 14 abuts the test surface through the through hole 111; then the wear resistance test of the test surface can be carried out.
