[0028] The technical solutions of the embodiments of the application are described in detail below with reference to the drawings.

[0029] Referring to Figures 1-2The concrete surface crack detection device, which comprises a support table 1, a moving mechanism 15 arranged at the bottom of the support table 1, a limiting groove 2 opened at the top of the support table 1, a sliding block 3 movably sleeved in the limiting groove 2, a support sleeve 4 fixedly connected to the top of the sliding block 3, an electric push rod 7 fixedly installed in the support sleeve 4, a lifting column 8 installed at the top of the electric push rod 7, the lifting column 8 penetrating through the top of the support sleeve 4 and being in sliding connection with the support sleeve 4, a rotating column 9 rotatably installed at the top of the lifting column 8, a detector body 10 fixedly installed at the top of the rotating column 9, a first gear 11 fixedly sleeved to the outside of the rotating column 9, and an adjusting mechanism 12 arranged at the top of the side of the lifting column 8 and comprising a second motor 121 fixedly installed at the top of the side of the lifting column 8 and a second gear 122 fixedly sleeved to the output shaft of the second motor 121 and in meshing connection with the first gear 11.

[0030] When working, the moving mechanism 15 drives the movement of the whole device, the sliding block 3 drives the horizontal movement of the detector body 10 through the support sleeve 4, the lifting column 8 and the rotating column 9, the electric push rod 7 drives the vertical movement of the detector body 10 through the lifting column 8 and the rotating column 9, and the second motor 121 drives the rotation of the detector body 10 through the second gear 122, the first gear 11 and the rotating column 9, so that the detector body 10 can shoot the whole crack, thereby achieving the crack shape detection effect and avoiding the problem that it is difficult to comprehensively detect the crack when the detection device is fixed, thereby improving the practicability of the detection device.

[0031] The top of the electric push rod 7 is fixedly connected to the bottom of the lifting column 8, and the electric push rod 7 is located at the middle part of the support sleeve 4. When adjusting the height of the detector body 10, the electric push rod 7 is started to drive the lifting column 8 to move up and down, that is, to drive the detector body 10 to move up and down, thereby achieving the adjusting effect of the working height of the detector body 10.

[0032] When it is necessary to adjust the detection angle of the detector body 10, the second motor 121 is started to drive the first gear 11 to rotate through the second gear 122, that is, to drive the detector body 10 to rotate through the rotating column 9, thereby achieving the adjusting effect of the detection angle of the detector body 10.

[0033] In some embodiments, referring to Figure 4 , the internal thread of the sliding block 3 is sleeved with a threaded column 5, a side of the support table 1 is fixedly provided with a first motor 6, one end of the threaded column 5 is fixedly connected with the output shaft of the first motor 6, and the threaded column 5 is movably sleeved in the internal of the limiting groove 2, and both ends thereof are rotatably connected with the wall surface of the limiting groove 2.

[0034] In operation, one end of the threaded column 5 is fixedly connected with the output shaft of the first motor 6, and the threaded column 5 is movably sleeved in the internal of the limiting groove 2; by arranging the threaded column 5, when the concrete surface crack width detection is completed, the first motor 6 is started, so that the first motor 6 drives the sliding block 3 to move horizontally through the threaded column 5, that is, the detector body 10 is driven to move horizontally through the support sleeve 4, so that the detector body 10 can shoot the whole crack, thereby achieving the crack whole shape detection effect, avoiding the problem that the detection device is difficult to detect the crack comprehensively when the position is fixed, and improving the practicability of the detection device.

[0035] In some embodiments, the bottom of the lifting column 8 is provided with a limiting plate, the limiting plate is in the internal of the support sleeve 4, the upper part of the lifting column 8 is provided with a limiting mechanism 13, the limiting mechanism 13 comprises a baffle 131, the baffle 131 is fixedly sleeved outside the lifting column 8, and the bottom of the baffle 131 is fixedly connected with a damping plate 132.

[0036] In operation, the limiting plate can prevent the lifting column 8 from coming out of the support sleeve 4, the material of the damping plate 132 is rubber material, by arranging the limiting mechanism 13, when the height of the detector body 10 is adjusted, the baffle 131 can limit the lifting amplitude of the lifting column 8, so that the problem that the detector body 10 hits the top of the support sleeve 4 when the lifting column 8 moves up and down is avoided, thereby improving the safety of the detector body 10 when moving up and down.

[0037] In some embodiments, referring to Figure 3 , the internal cavity of the limiting groove 2 is movably sleeved with a sliding ball 14, and the sliding balls 14 are uniformly distributed on the bottom of the internal cavity of the limiting groove 2.

[0038] In operation, the number of the sliding balls 14 is several, and the several sliding balls 14 are uniformly distributed on the bottom of the internal cavity of the limiting groove 2; by arranging the sliding ball 14, when the position of the support sleeve 4 is adjusted, the sliding ball 14 can support and limit the horizontally moving sliding block 3, so that the problem that the sliding block 3 rubs against the bottom of the internal cavity of the limiting groove 2 when moving horizontally is avoided, thereby improving the smoothness of the sliding block 3 when moving horizontally, that is, improving the smoothness of the detector body 10 when moving horizontally.

[0039] In some embodiments, the moving mechanism 15 comprises a support column 151 fixedly connected to the bottom of the support table 1, and a sliding wheel 152 is installed at the bottom of the support column 151.

[0040] In operation, by setting the moving mechanism 15, when the detection device is moved for conveying, the support table 1 is pushed so that the sliding wheel 152 drives the support table 1 to move horizontally through the support column 151, i.e. drives the detector body 10 to move horizontally, thereby achieving the effect of moving and conveying the crack detection device, and further facilitating the adjustment of the working position of the crack detection device.

[0041] Working process of the application:

[0042] First step: first, when the concrete surface crack width detection is completed, start the first motor 6 so that the first motor 6 drives the sliding block 3 to move horizontally through the threaded column 5, i.e. drives the detector body 10 to move horizontally through the support sleeve 4, thereby enabling the detector body 10 to take a picture of the overall crack, thereby achieving the effect of detecting the overall shape of the crack, avoiding the problem that it is difficult to detect the crack comprehensively when the detection device is fixed, thereby improving the practicality of the detection device. When adjusting the height of the detector body 10, start the electric push rod 7 so that the electric push rod 7 drives the lifting column 8 to move up and down, i.e. drives the detector body 10 to move up and down, thereby achieving the effect of adjusting the working height of the detector body 10. When detecting the concrete crack, move the detector body 10 to the side of the crack, and then start the detector body 10 so that the detector body 10 can take pictures and measure the crack, thereby enabling the detector body 10 to transmit the crack detection data to the display terminal, thereby achieving the effect of detecting the crack. When the detection angle of the detector body 10 needs to be adjusted, start the second motor 121 so that the second motor 121 drives the first gear 11 to rotate through the second gear 122, i.e. drives the detector body 10 to rotate through the rotating column 9, thereby achieving the effect of adjusting the detection angle of the detector body 10.

[0043] Second step: when the detector body 10 height adjustment is carried out, the baffle 131 can limit the lifting column 8 lifting amplitude, so that the detector body 10 is avoided to hit the support sleeve 4 top when the lifting column 8 moves up and down, thereby improving the safety of the detector body 10 up and down movement, when the support sleeve 4 position adjustment is carried out, the sliding ball 14 can support the sliding block 3 horizontal movement limiting groove 2, so that the sliding block 3 horizontal movement is avoided to rub with the limiting groove 2 inner cavity bottom, thereby improving the smoothness of the sliding block 3 horizontal movement, that is, improving the smoothness of the detector body 10 horizontal movement, when the detection device moves, the supporting table 1 is pushed, so that the sliding wheel 152 can drive the supporting table 1 horizontal movement through the supporting column 151, that is, drive the detector body 10 horizontal movement, thereby achieving the crack detection device moving conveying effect, and further facilitating the crack detection device working position adjustment.
