[0029] As a technical optimization scheme of the utility model, the knocking mechanism comprises a groove 16 formed in the end of the mounting plate 6 away from the fixed plate 5, and a rotating block 12 is rotatably installed in the inside of the groove 16.

[0030] As a technical optimization scheme of the utility model, the outer wall of the side of the mounting plate 6 away from the fixed plate 5 is provided with two circular grooves 22 in communication with the groove 16, two springs 23 are installed in the insides of the two circular grooves 22, one end of each of the two springs 23 away from the circular groove 22 is connected with the rotating block 12, and a handheld part 13 is installed on the outer wall of the side of the rotating block 12 away from the rail body 1. The handheld part 13 is manually pulled, the rotating block 12 is driven to rotate in the inside of the groove 16 towards the direction away from the mounting plate 6, and the two springs 23 are driven to be in the elongated state, the restriction on the handheld part 13 is manually released, the rotating block 12 is driven to rotate and reset by the elastic reset of the two springs 23, the knocking block 14 provided on the outer wall of the side of the rotating block 12 close to the mounting plate 6 is driven to collide with the rail body 1, and the rail body 1 can be conveniently knocked and detected to detect whether there is a fracture problem in the inside of the rail body 1.

[0031] As a technical optimization scheme in the utility model, two fixed sleeves 21 are installed on the outer wall of the side of the mounting plate 6 away from the fixed plate 5, and the inside of the two fixed sleeves 21 is jointly inserted with an insertion rod 15 for limiting and fixing the position of the rotating block 12. Because the rotating block 12 and other components are arranged at the end of the two mounting plates 6 away from the fixed plate 5, in order to avoid that the rotating plate 3 is hindered by the two rotating blocks 12 and other components during the rotation between the two sleepers 2, when the rotating plate 3 needs to drive the two mounting plates 6 and other components to rotate downward to between the two sleepers 2, the two handheld parts 13 are manually pulled in sequence, the two rotating blocks 12 are driven to rotate upward in the corresponding grooves 16 to be in a horizontal state in sequence, then the two insertion rods 15 are inserted into the inside of the corresponding two fixed sleeves 21 in sequence, the position of the rotating block 12 after upward rotation is limited and fixed, and the two rotating blocks 12 are prevented from continuing to rotate downward and reset by the elasticity of the spring 23, after the rotating plate 3 drives the two mounting plates 6 and other components to rotate and adjust, the two insertion rods 15 are slid out from the inside of the corresponding two fixed sleeves 21, so that the two rotating blocks 12 can be elastically reset by the corresponding two springs 23.

[0032] In the utility model, after the rail body 1 is completed and has not been put into use, the rotating plate 3 and other components are installed between the two sleepers 2 at the positions with greater wear degree in the curved track, slope and heavy load line in the rail body 1, after the rotating plate 3 is controlled to rotate upward to be in a vertical state and drives the fixed plate 5 and the two mounting plates 6 to rotate to the top of the rail body 1, the two nuts 10 are loosened, the moving plate 4 is affected by the gravity of the components above and slides downward in the rotating plate 3, until the bottom end of the two mounting plates 6 abuts against the top end of the rail body 1, then the two nuts 10 are tightened to limit and fix the position of the moving plate 4 in the rotating plate 3, and then the rotating plate 3 drives the moving plate 4 and other components to rotate downward to be placed between the two sleepers 2, so that the use of the rail body 1 is not affected.

[0033] After the rail body 1 is used for a period of time, the rotating plate 3 drives the moving plate 4 and other components to rotate upward by 90 degrees, so that the bottom end of the two mounting plates 6 abuts against the top end of the rail body 1, at this time, the two laser two-dimensional sensors 7 are in contact with the top end of the rail body 1 to automatically detect the wear degree of the top of the rail body 1, so that the wear degree of the top of the rail body 1 is automatically detected.

[0034] With the continuous use of the rail body 1, the distance between the rail body 1 and the bottom end of the two laser two-dimensional sensors 7 increases, so that the two laser two-dimensional sensors 7 cannot accurately detect the top of the rail body 1 due to the increase in the distance from the top end of the rail body 1. When the two nuts 10 are loosened again, the moving plate 4 is moved downward in the interior of the rotating plate 3, ensuring that the two mounting plates 6 abut against the top of the rail body 1, so that the height of the two laser two-dimensional sensors 7 can be adjusted synchronously with the degree of wear of the top of the rail body 1, ensuring that the two laser two-dimensional sensors 7 can always accurately detect the top of the rail body 1 during long-term use.

[0035] During the detection of the degree of wear of the top of the rail body 1 by the two laser two-dimensional sensors 7, the rotation of the double-headed screw rod 18 can drive the two moving blocks 19 to move away from each other, thereby adjusting the distance between the two mounting plates 6 and the laser two-dimensional sensors 7, so that the range of detection of the degree of wear of the top of the rail body 1 by the two laser two-dimensional sensors 7 is larger.

[0036] When the device is not needed to detect the degree of wear of the top of the rail body 1, after the two insertion rods 15 limit and fix the position of the rotating block 12 after being rotated upward, the rotating plate 3 is controlled to rotate downward, thereby driving the two mounting plates 6 and other components to rotate together from the top of the rail body 1 to between the two sleepers 2, without hindering the subsequent operation of the track vehicle.

[0037] When the rail body 1 is used in a cold region low-temperature environment, the brittleness of steel materials increases in a low-temperature environment, which causes the rail body 1 to be more prone to breaking during use. Therefore, while detecting the degree of wear of the top of the rail body 1, the staff also needs to knock the rail body 1 at regular intervals to detect whether there is a breakage in the rail body 1, to ensure that the rail body 1 can be used normally in a cold region low-temperature environment. When it is necessary to knock the rail body 1 for detection, the two insertion rods 15 are slid out of the interiors of the two fixed sleeves 21, the handheld portion 13 is manually pulled, the rotating block 12 is rotated in the interior of the groove 16 away from the mounting plate 6, the two springs 23 are elongated, the restriction on the handheld portion 13 is manually released, the elastic reset of the two springs 23 drives the rotating block 12 to rotate and reset together, and the knocking block 14 provided on the side of the rotating block 12 close to the mounting plate 6 collides with the rail body 1, thereby facilitating the knocking detection of the rail body 1. In combination with the rotation of the double-headed screw rod 18, the two mounting plates 6 are moved away from each other for adjustment, further improving the range of the two knocking mechanisms for knocking detection of the rail body 1, thereby improving the sustained and durable use performance of the entire device during actual use.

[0038] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
