Technical Field

[0001] The utility model relates to the technical field of hydraulic building detection, and particularly relates to a crack detection device for hydraulic buildings. Background Art

[0002] Buildings constructed for water conservancy and flood control are called hydraulic buildings. Since hydraulic buildings are in long-term contact with water and some hydraulic buildings also bear water pressure, it is necessary to regularly detect cracks in hydraulic buildings to evaluate their stability. Chinese Patent CN202321712433.0 discloses a building crack detection device, including a main body and a probe. A telescopic rod is arranged on the back side of the main body away from the display screen. The probe is arranged at the telescopic end of the telescopic rod and is electrically connected to the main body. Four support rods are arranged on the back side of the main body away from the display screen. The four support rods are all perpendicular to the main body and are located on both sides of the telescopic rod. This device drives the probe to move upward on the main body by using the telescopic rod, and positions the main body by using the four support rods to abut against the wall, so that the probe can be kept stable, thereby making the detection result more accurate when the crack detection device detects cracks at higher positions.

[0003] The existing detection devices have the following problems: The measurement angle is not easy to adjust, and it is not convenient to measure hydraulic buildings with inclined surfaces, such as the side surface of a dam is an inclined surface.

[0004] Based on the above situation, there is an urgent need for a crack detection device for hydraulic buildings to solve the problem that the measurement angle is not easy to adjust. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the measurement angle is not easy to adjust for the existing detection devices, which are not convenient for measuring hydraulic buildings, such as the side surface of a dam is an inclined surface.

[0011] Furthermore, the lifting mechanism (3) includes a main pulling rope (31) connected to the movable platform (1). The main pulling rope (31) is connected to a lifting drum (32), and the lifting drum (32) is connected to a first bidirectional motor (33).

[0012] Furthermore, the angle adjustment mechanism (2) includes a mounting plate (21) provided on the main pulling rope (31). A adjusting drum (22) and a second bidirectional motor (23) for driving the adjusting drum (22) are mounted on the mounting plate (21).

[0030] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0031] Embodiment:

[0032] Please refer to Figure 1 and Figure 2 , a crack - detection device for hydraulic structures, comprising:

[0033] A moving platform 1, on which a measuring instrument 11 for detecting cracks is installed;

[0034] An angle - adjusting mechanism 2, which is arranged above the moving platform 1 and is used to adjust the inclination angle of the moving platform 1;

[0035] The lifting mechanism 3 is connected to the angle adjustment mechanism 2 and is used for the overall lifting of the movable platform 1 and the angle adjustment mechanism 2.

[0036] For existing detection equipment, since its measurement angle is not easy to adjust, it is not convenient to measure hydraulic structures, such as the side of a dam being an inclined plane; in this solution, the inclination angle of the movable platform 1 is adjusted through the angle adjustment mechanism 2, and then the measurement angle of the measuring instrument 11 is changed, which can adapt to the crack detection of different inclined-plane hydraulic structures and solve the problem that the measurement angle is not easy to adjust. The lifting mechanism 3 drives the movable platform 1 to lift to detect different heights and angle positions of the hydraulic structure, solving the problem that the measurement angle is not easy to adjust.

[0037] Refer to Figure 3 , since some hydraulic structures are relatively high, in order to solve the problem that the detection height of traditional telescopic rods is limited, one feasible solution is: the lifting mechanism 3 includes a main pulling rope 31 connected to the movable platform 1, the upper end of the main pulling rope 31 is connected to a lifting drum 32 and the lifting drum 32 is connected to a first bidirectional motor 33. When this solution is adopted, the first bidirectional motor 33 drives the lifting drum 32 to rotate to pull or release the main pulling rope 31, and then the movable platform 1 reaches the specified height. Compared with the traditional telescopic rod solution, the height adjustment is more convenient, improving the detection range and space.

[0038] Refer to Figure 3 and Figure 4 , this solution does not uniquely limit the specific structure of the angle adjustment mechanism 2. One feasible solution is: the angle adjustment mechanism 2 includes a mounting plate 21 arranged on the main pulling rope 31, the mounting plate 21 is equipped with an adjustment drum 22 and a second bidirectional motor 23 for driving the adjustment drum 22, and a secondary pulling rope 24 is arranged between the adjustment drum 22 and the movable platform 1. When this solution is adopted, the second bidirectional motor 23 drives the adjustment drum 22 to rotate, and then pulls or releases the secondary pulling rope 24, thereby achieving the adjustment of the inclination angle of the movable platform 1.

[0039] In order to facilitate the adjustment of the movable platform 1 to a preset inclination angle, one feasible solution is: an angle meter 25 is installed on the movable platform 1. When this solution is adopted, the angle data obtained by the angle meter 25 can be used to control the second bidirectional motor 23. By observing the angle value displayed by the angle meter 25, the movable platform 1 can be conveniently and quickly adjusted to the preset inclination angle.

[0040] Refer to Figure 4 , in order to protect the measuring instrument 11, one feasible solution is: a baffle 12 is installed on the movable platform 1. When this solution is adopted, through the protection of the baffle 12, the measuring instrument 11 can be prevented from being scratched by the hydraulic structure.

[0041] A rotating wheel 13 is installed on the baffle 12. When this solution is adopted, it can effectively protect the baffle 12 and prevent sliding friction between the baffle 12 and the hydraulic structure.

[0042] The working principle of this embodiment:

[0043] Install the lifting mechanism 3 on the top or corresponding position of the hydraulic structure. Drive the adjusting roller 22 to rotate through the second bidirectional motor 23, so that the adjusting roller 22 rotates to pull or release the secondary pulling rope 24. With the assistance of the angle gauge 25, adjust the movable platform 1 to the preset inclination angle. The first bidirectional motor 33 drives the lifting roller 32 to release the main pulling rope 31. The movable platform 1 and the measuring instrument 11 synchronously descend to the corresponding position under the action of gravity, and the hydraulic structure is detected for cracks through the measuring instrument 11.

[0044] To solve the problem that the measurement angle is not easy to adjust, in this solution, the inclination angle of the movable platform 1 is adjusted through the angle adjustment mechanism 2, and then the measurement angle of the measuring instrument 11 is changed, which can adapt to the crack detection of hydraulic structures with different inclined surfaces. The lifting mechanism 3 drives the movable platform 1 to lift and lower to detect different height positions of the hydraulic structure.

[0045] To improve the detection range, in this solution, since the lifting mechanism 3 includes a main pulling rope 31 connected to the movable platform 1, the main pulling rope 31 is connected to a lifting roller 32 and the lifting roller 32 is connected to a first bidirectional motor 33. The first bidirectional motor 33 drives the lifting roller 32 to rotate to pull or release the main pulling rope 31, so that the movable platform 1 reaches the specified height. Compared with the traditional telescopic rod solution, the height adjustment is more convenient, and the detection range and space are improved.

[0046] To realize the inclination angle adjustment of the movable platform 1, in this solution, since the angle adjustment mechanism 2 includes a mounting plate 21 arranged on the main pulling rope 31, an adjusting roller 22 and a second bidirectional motor 23 for driving the adjusting roller 22 are installed on the mounting plate 21. A secondary pulling rope 24 is arranged between the adjusting roller 22 and the movable platform 1. The second bidirectional motor 23 drives the adjusting roller 22 to rotate, and then pulls or releases the secondary pulling rope 24, thereby adjusting the inclination angle of the movable platform 1.

[0047] Compared with the existing technology, the beneficial effects of the present utility model are:

[0048] First, the inclination angle of the movable platform is adjusted through the angle adjustment mechanism, and then the measurement angle of the measuring instrument can be changed, which can adapt to the crack detection of hydraulic structures with different inclined surfaces. The lifting mechanism drives the movable platform to lift and lower to detect different height positions of the hydraulic structure, solving the problem that the measurement angle is not easy to adjust;

[0049] Second, since the lifting mechanism includes a main pulling rope connected to the movable platform, the main pulling rope is connected to a lifting drum, and the lifting drum is connected to a first bidirectional motor. The first bidirectional motor drives the lifting drum to rotate to pull or release the main pulling rope, thereby enabling the movable platform to reach a specified height. Compared with the traditional telescopic rod solution, the height adjustment is more convenient, improving the detection range and space.

[0050] Third, since the angle adjustment mechanism includes a mounting plate disposed on the main pulling rope, an adjustment drum and a second bidirectional motor for driving the adjustment drum are mounted on the mounting plate, and an auxiliary pulling rope is disposed between the adjustment drum and the movable platform. By driving the adjustment drum to rotate with the second bidirectional motor, the auxiliary pulling rope is pulled or released, thereby adjusting the inclination angle of the movable platform, which has the advantage of convenient inclination angle adjustment.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
