[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0036] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0037] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0038] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "below," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0040] Figure 1 It is a schematic diagram of the overall structure of a bridge steel structure crack detection device according to an embodiment of the present disclosure.

[0041] Figure 2 It is a schematic structural diagram of a lifting mechanism 2 and a resetting mechanism 4 of a bridge steel structure crack detection device according to an embodiment of the present disclosure.

[0042] Figure 3 It is a schematic structural diagram of a spacing adjustment mechanism 3 and a reset mechanism 4 of a bridge steel structure crack detection device according to an embodiment of the present disclosure.

[0043] like Figure 1-Figure 3 As shown, the bridge steel structure crack detection device disclosed in the present invention may include: a moving frame 1, a lifting mechanism 2, a spacing adjustment mechanism 3, a reset mechanism 4 and a flip clamping mechanism 5 and other components.

[0044] like Figure 2 As shown, in the present disclosure, the lifting mechanism 2 includes a lifting shell 21, a guide rod 22 and an adjusting bolt 23, wherein the lifting shell 21 is located on the inner side of the moving frame 1, the guide rod 22 slides through the moving frame 1 and is fixedly connected to the lifting shell 21, the adjusting bolt 23 penetrates the moving frame 1 and is threadedly connected to the lifting shell 21, and the bottom end of the adjusting bolt 23 is rotatably nested in the top of the lifting shell 21 through a bearing.

[0045] Therefore, it is convenient to rotate the adjusting bolt 23, so that the adjusting bolt 23 drives the lifting housing 21 to descend, and when the lifting housing 21 descends, the transmitting probe and the receiving probe are driven to descend synchronously.

[0046] like Figure 3As shown, in a preferred embodiment, the spacing adjustment mechanism 3 includes a locking hole 31, a locking rod 32, an adjusting rod 33 and a shuttle-shaped push block 34, wherein a plurality of locking holes 31 are provided, and a plurality of locking holes 31 are evenly opened on the top of the movable frame 1, and the locking rod 32 is slidably arranged on the inner side of any locking hole 31 along the vertical direction, and the adjusting rod 33 is fixedly arranged at the top end of the locking rod 32, and the adjusting rod 33 slides through the movable frame 1 and the lifting shell 21 and extends to the inside of the lifting shell 21, and the shuttle-shaped push block 34 is fixedly arranged at the bottom end of the adjusting rod 33.

[0047] Therefore, it is convenient to pull the adjusting rod 33 upward, so that the adjusting rod 33 drives the locking rod 32 to move out from the inside of the adjacent locking hole 31 to release the lock, and then rotate the adjusting rod 33, so that the adjusting rod 33 drives the shuttle-shaped push block 34 to push the reset mechanism 4 to complete the adjustment of the distance between the transmitting probe and the receiving probe, and finally press the adjusting rod 33 to make the locking rod 32 enter the adjacent locking hole 31 again to lock it.

[0048] It should also be noted that when the lifting shell 21 descends, the shuttle-shaped push block 34 rises relatively inside the lifting shell 21 .

[0049] like Figure 2 As shown, in the present disclosure, the reset mechanism 4 includes a moving block 41, a reset spring 42 and an end plate 43, wherein the moving block 41 is slidably arranged inside the lifting shell 21, the reset spring 42 is fixedly connected between the moving block 41 and the end plate 43, and the end plate 43 is fixedly connected to the inner wall of the lifting shell 21.

[0050] Therefore, when the moving block 41 is pushed, the moving block 41 stretches the reset spring 42, and at the same time drives the outer side of the clamping seat 53 through the rotating shaft 51, thereby adjusting the distance between the transmitting probe and the receiving probe. When the moving block 41 is no longer pushed, the stretched reset spring 42 drives the moving block 41 to reset, and the moving block 41 drives the clamping seat 53 to reset through the rotating shaft 51.

[0051] like Figure 3 As shown, in a preferred embodiment, the flipping and clamping mechanism 5 includes a rotating shaft 51, a long gear 52, a clamping seat 53, a side plate 54 and a rack 55, wherein the rotating shaft 51 is rotatably nested at the end of the moving block 41 through a bearing, the long gear 52 is fixedly sleeved on the outside of the rotating shaft 51, the clamping seat 53 is fixedly set at the end of the rotating shaft 51, the side plate 54 is fixedly set on the side of the moving frame 1, and the rack 55 is fixedly set at the bottom of the side plate 54 and meshes with the long gear 52.

[0052] In this way, it is convenient to insert the transmitting probe and the receiving probe into the inner side of the two clamping seats 53 through the top openings of the two clamping seats 53, and then complete the clamping and fixing. When the lifting mechanism 2 drives the reset mechanism 4 to move downward, the reset mechanism 4 drives the rotating shaft 51, the long gear 52 and the clamping seat 53 to move downward synchronously. During the downward movement of the long gear 52, it rotates under the action of the rack 55, and then drives the clamping seat 53 to rotate through the rotating shaft 51, so that the two clamping seats 53 respectively drive the transmitting probe and the receiving probe to contact the ground to start the crack detection operation.

[0053] It should also be noted that the transmitting probe and the receiving probe are both existing technologies and are not necessary technical features of the present application. Therefore, the present application does not elaborate on their specific structures and detection principles.

[0054] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.
