[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Embodiment 1: As Figure 1-8 shown, the present invention provides a crack measurement device for high-speed railway base inspection, including a transfer mechanism 1. There are two transfer mechanisms 1, and an H-shaped frame 2 is fixedly installed at the top ends of the two transfer mechanisms 1. A first measurement mechanism 3 is provided at the upper end of the H-shaped frame 2, and the bottom end of the first measurement mechanism 3 is fixedly connected to a second measurement mechanism 4. An auxiliary mechanism 5 for cooperative use is provided on the second measurement mechanism 4, and a cleaning mechanism 6 is fixedly connected to one side of the bottom end of the second measurement mechanism 4. The cleaning mechanism 6 is used to clean the dust in the crack.

[0028] The transfer mechanism 1 includes a transfer frame 11. In the middle of the top end of the transfer frame 11, a rectangular frame 21 is fixedly installed. The bottom end of the H-shaped frame 2 is fixedly connected to the transfer frame 11, and the rectangular frame 21 is fixedly sleeved on the outside of the H-shaped frame 2. At the top end of the H-shaped frame 2, symmetrically arranged wedge-shaped support plates 22 are fixedly installed. Through the combined use of the rectangular frame 21 and the wedge-shaped support plates 22, the installation firmness of the H-shaped frame 2 is effectively improved, thus ensuring the stable use of the crack measurement device. On both sides of the bottom end of the transfer frame 11, universal wheels 12 are fixedly installed. A first lead screw 13 is threadedly inserted into the transfer frame 11, and the bottom end of the first lead screw 13 is rotatably connected to a positioning disc 14. On the side of the positioning disc 14 away from the transfer frame 11, anti-slip protrusions 15 distributed in an array are fixedly installed. One end of the first lead screw 13 away from the positioning disc 14 is fixedly connected to a first rotating wheel 16, and an anti-slip pattern is covered on the outer wall of the first rotating wheel 16. The setting of the first rotating wheel 16 provides convenience for the rotational adjustment of the first lead screw 13, and the anti-slip pattern can play a role in increasing friction and facilitating operation.

[0029] By adopting the above technical solution, during use, the user can push the H-shaped frame 2 and, in conjunction with the use of the universal wheels 12, move the crack measurement device to the crack on the high-speed railway base. Subsequently, the H-shaped frame 2 can be adjusted to be perpendicular to the crack. Then, the user can rotate the first rotating wheel 16, which can drive the first lead screw 13 to rotate, and then drive the positioning disc 14 to rotate and move it to the side away from the transfer frame 11. When the anti-slip protrusions 15 contact the ground, the first rotating wheel 16 can continue to be rotated. At this time, the positioning disc 14 will stop rotating, and the distance between the positioning disc 14 and the transfer frame 11 will continue to increase until the anti-slip protrusions 15 are deformed and the positioning disc 14 is in close contact with the ground.

[0030] The first measurement mechanism 3 includes a second lead screw 31 and a first scale plate 32. The second lead screw 31 is rotatably inserted into the upper end of the H-shaped frame 2. One end of the second lead screw 31 is fixedly connected to a second rotating wheel 38, and a driving rocker 39 is rotatably inserted into the second rotating wheel 38. Through the combined use of the driving rocker 39 and the second rotating wheel 38, it provides convenience for the rotational adjustment of the second lead screw 31. A driving screw cylinder 33 is threadedly sleeved on the outside of the second lead screw 31. A moving slider 34 is fixedly sleeved on the outside of the driving screw cylinder 33. On both sides of the upper end of the moving slider 34, first pointers 35 are fixedly installed. The first scale plate 32 is fixedly installed on the H-shaped frame 2 and is symmetrically distributed. The first pointers 35 are in sliding contact with the first scale plate 32. A transverse guide rod 36 is fixedly inserted into the upper end of the H-shaped frame 2, and a guiding through hole 37 is opened through the moving slider 34. The transverse guide rod 36 slidably penetrates through the guiding through hole 37.

[0031] By adopting the above technical solution, when it is necessary to measure the width of a crack, the user can rotate the driving rocker 39, which can drive the second runner 38 to rotate, and then drive the second lead screw 31 to rotate. At the same time when the second lead screw 31 rotates, it will cooperate with the use of the transverse guide rod 36 and the guiding perforation 37 to drive the moving slider 34 to move, so as to drive the second measuring mechanism 4 to move until the second measuring mechanism 4 is moved to the upper end of one side of the crack. After that, the user can stop rotating the driving rocker 39 and record the position where the first pointer 35 points to the first scale plate 32 at this time. Then the user can adjust the second measuring mechanism 4 to a suitable position. After that, the user can continue to rotate the driving rocker 39, which can drive the second lead screw 31 to rotate again through the second runner 38, and then drive the second measuring mechanism 4 to move again through the moving slider 34 until it is moved to the upper end of the other side of the crack. At this time, the user can stop rotating the driving rocker 39 and record the position on the first scale plate 32 where the first pointer 35 points again, so as to obtain the width of the crack.

[0032] The second measuring mechanism 4 includes a measuring outer frame 41, and the measuring outer frame 41 is fixedly connected to the bottom end of the moving slider 34. A measuring slide rod 42 is slidably inserted into the inner cavity of the measuring outer frame 41, and a transverse carrier plate 43 is fixedly installed at the bottom end of the measuring slide rod 42, and a measuring pointer 44 is fixedly installed in the middle of the bottom end of the transverse carrier plate 43. As Figure 7 shown, in order to clearly see the structure of the measuring slide rod 42, Figure 7Components such as the measuring slide bar 42 are placed outside the measuring outer frame 41. A driving slide bar 45 is fixedly installed at the upper end of the measuring slide bar 42, and symmetrically arranged first through slots 46 are formed through the measuring outer frame 41. The driving slide bar 45 is slidably clamped in the first through slots 46. A second through slot 47 is formed through one side of the measuring outer frame 41, and a positioning screw hole 48 for cooperating with the second through slot 47 is formed at the upper end of the measuring slide bar 42. A positioning bolt 49 can be threadedly inserted into the positioning screw hole 48, and the positioning bolt 49 can be movably inserted into the second through slot 47. The driving slide bar 45 is fixed by making the bolt head of the positioning bolt 49 closely adhere to the outer wall of the measuring outer frame 41. Symmetrically distributed second pointers 410 are fixedly installed on the driving slide bar 45, and symmetrically distributed second scale plates 411 are fixedly installed on the outside of the measuring outer frame 41. The second pointers 410 are in sliding contact with the second scale plates 411. The auxiliary mechanism 5 includes a side connection guide block 51 and a side connection support column 52. The side connection guide block 51 is fixedly connected to the driving slide bar 45, and the side connection guide block 51 has a symmetrical structure. A driving grip bar 53 is slidably inserted into the two side connection guide blocks 51, and an arc-shaped groove 412 is formed in the driving slide bar 45. The driving grip bar 53 can be slidably clamped in the arc-shaped groove 412, and a first ring 54 is fixedly connected to the driving grip bar 53. The side connection support column 52 is fixedly connected to the measuring slide bar 42, and a third through slot 413 for cooperating with the side connection support column 52 is formed through the measuring outer frame 41. The side connection support column 52 is slidably inserted into the third through slot 413, and the first ring 54 is slidably sleeved on the side connection support column 52. A return spring 55 is fixedly installed on one side of the first ring 54, and the return spring 55 is movably sleeved on the side connection support column 52. The end of the return spring 55 away from the first ring 54 is fixedly connected to a second ring 56, and the second ring 56 is fixedly sleeved on the side connection support column 52.

[0033] By adopting the above technical solution, during use, the user can rotate the positioning bolt 49 until the bolt head of the positioning bolt 49 is separated from the outer wall of the measuring outer frame 41. Then, the user can push the driving grip bar 53 and move it towards the side close to the measuring outer frame 41, thereby driving the first ring 54 to move and compress the return spring 55. When the driving grip bar 53 is clamped into the arc-shaped groove 412, tightly hold the driving grip bar 53 and the driving slide bar 45, and then drive the driving grip bar 53 and the driving slide bar 45 to move downward, further driving the measuring slide bar 42 to move downward, and further driving the measuring pointer 44 to move downward through the transverse carrier plate 43 until the bottom end of the measuring pointer 44 is flush with the upper part of the high-speed railway base. After that, the user can release the driving grip bar 53. At this time, the return spring 55 will drive the first ring 54 to reset, so that the first ring 54 is closely attached to the outer wall of the measuring outer frame 41. Then, the user can release the driving slide bar 45 and rotate the positioning bolt 49 in the reverse direction until the bolt head of the positioning bolt 49 is closely attached to the outer wall of the measuring outer frame 41 again.

[0034] The cleaning mechanism 6 includes an air collecting box cover 61. The air collecting box cover 61 is fixedly connected to the transverse carrier plate 43, and a driving motor 62 is fixedly installed at the top end of the air collecting box cover 61. In this solution: The driving motor 62 is preferably of the Y80M1-2 model. The power supply interface of the motor is connected to the power supply system through a switch. The operating circuit of the driving motor 62 is a conventional forward and reverse control program for the driving motor 62. The circuit operation is an existing conventional circuit. The circuits and controls involved in this solution are all prior arts and will not be elaborated here. The end of the output end of the driving motor 62 is fixedly connected to a driving rotating rod 63, and the driving rotating rod 63 is rotatably inserted on the air collecting box cover 61. A driving fan blade 64 is fixedly sleeved at the bottom end of the driving rotating rod 63, and a ventilation inclined groove 65 for cooperating with the driving fan blade 64 is opened at the bottom end of the air collecting box cover 61. A filtering disc 66 for cooperating with the driving fan blade 64 is fixedly inserted on one side of the air collecting box cover 61. A transverse rotating rod 67 is rotatably inserted on the filtering disc 66, and a cleaning scraper 68 is fixedly connected to one end of the transverse rotating rod 67. The cleaning scraper 68 is movably attached to the outer wall of the filtering disc 66, and a first bevel gear 69 is fixedly connected to the end of the transverse rotating rod 67 away from the cleaning scraper 68. A second bevel gear 610 is fixedly sleeved on the driving rotating rod 63, and the second bevel gear 610 meshes with the first bevel gear 69.

[0035] By adopting the above technical solution, when in use, the driving motor 62 can be turned on. At this time, the driving motor 62 will drive the driving rotating rod 63 to rotate, so as to drive the second bevel gear 610 and the driving fan blade 64 to rotate, and then the outside air can be filtered by the filtering disc 66 and guided into the crack through the ventilation inclined groove 65, further effectively cleaning the dust in the crack. And while the second bevel gear 610 is rotating, it will drive the transverse rotating rod 67 to rotate through the first bevel gear 69, so as to drive the cleaning scraper 68 to rotate, and then the dust attached to the outer wall of the filtering disc 66 can be scraped off.

[0036] Working principle: When it is necessary to measure the width of the crack, the user can push the H-shaped frame 2 and cooperate with the use of the universal wheels 12 to move the crack measuring device to the crack on the high-speed railway base. Subsequently, the H-shaped frame 2 can be adjusted to be perpendicular to the crack. Then the user can rotate the first rotating wheel 16, so as to drive the first lead screw 13 to rotate, and then drive the positioning disc 14 to rotate and move it to the side away from the transfer rack 11. When the anti-slip protrusion 15 contacts the ground, the first rotating wheel 16 can be continuously rotated. At this time, the positioning disc 14 will stop rotating, and the distance between the positioning disc 14 and the transfer rack 11 will continue to increase until the anti-slip protrusion 15 deforms and the positioning disc 14 is in close contact with the ground.

[0037] Subsequently, the user can rotate the driving rocker 39, which can drive the second runner 38 to rotate, and then drive the second lead screw 31 to rotate. While the second lead screw 31 is rotating, it will cooperate with the horizontal guide rod 36 and the guiding perforation 37 to drive the moving slider 34 to move, thereby driving the second measuring mechanism 4 to move until the measuring pointer 44 is moved to the upper end of one side of the crack. After that, the user can stop rotating the driving rocker 39 and record the position where the first pointer 35 points to the first scale plate 32 at this time. Then, the user can turn the positioning bolt 49. When the bolt head of the positioning bolt 49 is separated from the outer wall of the measuring outer frame 41, the user can then push the driving grip 53 and move it towards the side close to the measuring outer frame 41, which can drive the first ring 54 to move and compress the return spring 55. When the driving grip 53 is stuck in the arc-shaped groove 412, tightly hold the driving grip 53 and the driving slide rod 45, and then drive the driving grip 53 and the driving slide rod 45 to move downward, which can drive the measuring slide rod 42 to move downward, and further drive the measuring pointer 44 to move downward through the horizontal carrier plate 43 until the bottom end of the measuring pointer 44 is level with the upper part of the high-speed railway base. After that, the user can release the driving grip 53. At this time, the return spring 55 will drive the first ring 54 to reset, so that the first ring 54 can be closely attached to the outer wall of the measuring outer frame 41. Then, the user can release the driving slide rod 45 and reverse-turn the positioning bolt 49 until the bolt head of the positioning bolt 49 is closely attached to the outer wall of the measuring outer frame 41 again;

[0038] Then, the user can continue to turn the driving rocker 39, which can drive the second lead screw 31 to rotate again through the second runner 38, and then drive the measuring pointer 44 to move again through the moving slider 34 until the measuring pointer 44 is moved to the upper end of the other side of the crack. At this time, the user can stop rotating the driving rocker 39 and record the position on the first scale plate 32 pointed by the first pointer 35 again, so as to obtain the width of the crack;

[0039] During this period, the user can turn on the driving motor 62. At this time, the driving motor 62 will drive the driving rotating rod 63 to rotate, which can drive the second bevel gear 610 and the driving fan blade 64 to rotate, and then filter the outside air through the filter disc 66 and guide it into the crack through the ventilation chute 65, and further effectively clean the dust in the crack. While the second bevel gear 610 is rotating, it will drive the horizontal rotating rod 67 to rotate through the first bevel gear 69, which can drive the cleaning scraper 68 to rotate, and then scrape off the dust attached to the outer wall of the filter disc 66;

[0040] When the depth of the crack needs to be measured, the user can reverse the rotation of the driving rocker 39, so as to drive the second lead screw 31 to reverse through the second runner 38, and then drive the measuring pointer 44 to move back. When the measuring pointer 44 moves to the exact middle of the crack, stop rotating the driving rocker 39. At this time, the user can record the position on the second scale plate 411 pointed by the second pointer 410. Then the user can move down the measuring pointer 44 according to the above steps until the bottom end of the measuring pointer 44 touches the bottom end of the crack, and record the position on the second scale plate 411 pointed by the second pointer 410 again, so as to obtain the depth of the crack. After the measurement operation is completed, the user can perform the reverse operation according to the above steps to store the crack measuring device.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
