[0033] Referring to Figures 1 to 8 , in one embodiment of the present utility model, a crack detection device for a concrete structure in a cement project includes:
[0034] A rolling structure body 100, including a bracket and a roller assembly 120. The bracket includes a horizontal plate 111 and a vertical plate 112 that are connected to each other and arranged in an "L" shape. At both ends of the horizontal plate 111 in the length direction, close to and away from the vertical plate 112, first mounting holes 113 and second mounting holes 114 that are matched are respectively provided. On the vertical plate 112, third mounting holes 115 corresponding to the second mounting holes 114 and / or the second mounting holes 114 are provided. The roller assembly 120 is connected and extends beyond the free end of the vertical plate 112 in the length direction. In the middle of the horizontal plate 111 in the length direction and at one end in the width direction, a mounting seat 130 is connected;
[0035] A detection functional part 200, connected to the mounting seat 130;
[0036] A plurality of bolt assemblies are provided corresponding to the first mounting holes 113, the second mounting holes 114, and the third mounting holes 115.
[0037] In the prior art, although there are many types of devices for detecting cracks, how to perform a mechanical design structure that can be adapted to concrete structures of various structural types in a cement project is still a difficult point; for example, a detection device of one structure can only measure concrete structures with specific sizes, specific configurations, or specific characteristic directions.
[0038] In the present utility model, during the use of the crack detection device for a concrete structure in a cement project, except when the size of the concrete structure to be detected is small (for example, one side of a column), during the use process, a plurality of crack detection devices 010 need to be combined and used, and the combination method is limited to a linear connection method, and can also be combined according to actual situations.
[0039] The rolling structure 100 includes a bracket and a roller assembly 120. The bracket includes a horizontal plate 111 and a vertical plate 112 that are connected to each other in an "L" shape arrangement. The connection method between the horizontal plate 111 and the vertical plate 112 can be integrally formed, mechanically connected, welded, etc. At both ends of the horizontal plate 111 in the length direction, close to and away from the vertical plate 112, first mounting holes 113 and second mounting holes 114 that are formed to match are respectively provided. When connecting two rolling structures 100 in the length direction, the second mounting hole 114 of the horizontal plate 111 on the first rolling structure 100 corresponds to the first mounting hole 113 of the horizontal plate 111 on the second rolling structure 100, thereby forming a connection basis for the connection between the two. A third mounting hole 115 corresponding to the second mounting hole 114 and / or the second mounting hole 114 is provided on the vertical plate 112, forming a basis for forming a folding connection between the two rolling structures 100. By providing the third mounting hole 115 on the vertical plate 112, adjacent rolling structures 100 can achieve greater freedom during the process of mutual splicing of multiple crack detection devices 010 through the mutual connection between the vertical plate 112 and the horizontal plate 111, and thus can adapt to cement engineering concrete structures 020 with more shapes, or simultaneously adapt to multiple planes of the cement engineering concrete structure 020. In the above folding structure, it is necessary to adaptively disassemble a certain number of roller assemblies 120.
[0040] A mounting seat 130 is connected to the middle of the horizontal plate 111 in the length direction and at one end in the width direction. The detection functional part 200 is connected to the mounting seat 130. The implementation method of the detection functional part 200 can be a visible light, infrared light test part, ultrasonic wave, etc., which is not the focus in the present utility model specifically. The fixing method of the detection functional part 200 on the mounting seat 130 can be a threaded connection or a clamping connection, etc. According to different use environments or design concepts, the power supply of the detection functional part 200 can be set on the rolling structure 100 or in an external connection form. The roller assembly 120 is connected to and extends beyond the free end of the vertical plate 112 in the length direction. While the vertical plate 112 serves as the fixing basis of the roller assembly 120, it also forms a basis for forming a folding connection between the two rolling structures 100. When two roller assemblies 120 are connected, there will naturally be more than two roller assemblies 120 forming a support basis for the overall structure. Through the contact between the roller assembly 120 and the cement engineering concrete structure 020, rolling support is formed.
[0041] A plurality of bolt assemblies are arranged corresponding to the first mounting hole 113, the second mounting hole 114, and the third mounting hole 115. It should be noted that the number of bolt assemblies is not three, and they are not respectively arranged corresponding to the first mounting hole 113, the second mounting hole 114, and the third mounting hole 115. Specifically, as long as a fixed connection can be formed. For example, after the first mounting hole 113 on one rolling structure 100 is fixed to the second mounting hole 114 on another rolling structure 100, a bolt assembly passes through the first mounting hole 113 and the second mounting hole 114 to fix the two rolling structures 100.
[0042] During the use process: According to the specific shape of the concrete structure 020 of the cement project, a plurality of crack detection devices 010 are combined, so that the respective detection functional parts 200 on the crack detection devices 010 can detect cracks at corresponding positions. After the data collected by the detection functional part 200 is obtained, it can be directly analyzed, but the preferred method is to centrally process and analyze the data collected by the detection functional part 200 through processing. During the use process, by adding an attached track, the usage methods (vertical or inverted, etc.) of the crack detection devices 010 can also be increased.
[0043] In summary, according to the specific shape of the concrete structure 020 of the cement project, a plurality of crack detection devices 010 are combined, so that the respective detection functional parts 200 on the crack detection devices 010 can detect cracks at corresponding positions; when connecting two rolling structures 100 in the length direction, extension in length can be achieved; the adjacent rolling structures 100 can achieve a shape change through the mutual connection between the vertical plate 112 and the horizontal plate 111; while the vertical plate 112 serves as the fixed foundation for the roller assembly 120, it forms the foundation for forming a fold angle connection between the two rolling structures 100.
[0044] Refer to Figures 3 to 6 In one embodiment, a first notch 116 is provided on the back surface of the horizontal plate 111 near one end of the vertical plate 112, and a second notch 117 is provided on the front surface of the horizontal plate 111 far from one end of the vertical plate 112, wherein the thicknesses of the first notch 116 and the second notch 117 are the same.
[0045] In this embodiment, by designing the shape of the cross plate 111, a first notch 116 and a second notch 117 are respectively arranged at both ends of the cross plate 111 in the length direction. When two rolling structures 100 are joined end to end, a mortise and tenon structure is formed. For example, during the installation process, when two rolling structures 100 are joined in the length direction, the second notch 117 of the previous rolling structure 100 forms a connection with the first notch 116 of the subsequent rolling structure 100, and a fixed connection is formed through a bolt assembly. At this time, the heights of the mounting seats 130 are the same. Then when multiple rolling structures 100 are combined, the detection functional parts 200 on all the mounting seats 130 are at the same distance from the concrete structure 020, reducing the possibility of abnormal focusing. During the implementation process, the lengths of the first notch 116 and the second notch 117 can also be the same. Then when the two cross plates 111 are joined end to end, the first notch 116 and the second notch 117 can form an effect of mutual abutment, thereby improving the stability between the joined bodies.
[0046] In one embodiment, the length of the vertical plate 112 is the same as the length of the first notch 116.
[0047] In this embodiment, the length of the vertical plate 112 is limited, so that when two rolling structures 100 are joined at an angle, an abutment is formed between the vertical plate 112 and the first notch 116, and a stable connection can be formed between the vertical plate 112 and the first notch 116.
[0048] In one embodiment, it further includes a first driving part installed on the bracket, and the first driving part includes a first motor and a driving wheel connected to the output end of the first motor.
[0049] In this embodiment, a moving method of a crack detection device 010 is given. A first motor is installed on the bracket, and a driving wheel is arranged at the output end of the first motor. Then during the operation of the first motor, the interaction between the driving wheel and the external foundation makes the entire crack detection device 010 move. The number and type of the driving wheels are limited according to the actual situation, and the hardness of the driving wheels is moderately selected, so as to generate a certain buffering effect while providing stable support, and ensure the test results of the detection functional part 200.
[0050] In one embodiment, it further includes a second driving part, and the second driving part includes a second motor and a connecting cable;
[0051] Wherein, one end of the connecting cable in the length direction is detachably connected to the bracket, and the other end is wound around the output end of the second motor.
[0052] In this embodiment, considering that it is difficult to drive the entire crack detection device 010 in a rolling manner on a vertical surface. For example, on a vertical wall, first, and then, the second motor is installed at the top of the wall; then the two ends of the connecting cable are connected; finally, the rolling structure 100 is installed on the wall, and the operation of the second motor can achieve the lifting and lowering of the rolling structure 100 in the vertical direction.
[0053] In one embodiment, the detection functional part 200 is at least one of a visible light test part, an infrared light test part, and an ultrasonic test part.
[0054] In this embodiment, several common ways of the detection functional part 200 are given. It should be noted that the detection functional part 200 can be comprehensive. For example, it has both a visible light test part and an infrared light test part at the same time. During use, appropriate arrangements can be made at corresponding positions on the mounting base 130.
[0055] In one embodiment, the horizontal plate 111 and the vertical plate 112 are detachably arranged or integrally formed.
[0056] In this embodiment, two convenient combination ways between the horizontal plate 111 and the vertical plate 112 are given. The integrally formed way has the advantages of simplicity and reliable structure, while the detachable arrangement provides greater flexibility for the combination of multiple rolling structures 100. The specific detachable connection way between the horizontal plate 111 and the vertical plate 112 can be a combination of plugging and bolts.
[0057] Refer to Figures 7 to 8 , in one embodiment, it further includes a track 300;
[0058] A groove structure 310 corresponding to the roller assembly 120 is arranged in the length direction of the track 300.
[0059] In this embodiment, the track 300 is arranged in cooperation with the rolling structure 100 to restrict or even fix the movement direction of the rolling structure 100 through the track 300. Thus, during the use of the crack detection device 010, the movement process of the rolling structure 100 is more standardized, and then the entire detection process is more complete.
[0060] Refer to Figures 7 to 8 , in one embodiment, the roller assembly 120 forms a clamping fit with the groove structure 310 in the thickness direction of the track 300.
[0061] In this embodiment, the combination between the roller assembly 120 and the groove structure 310 is restricted, and the groove structure 310 restricts the roller assembly 120 from coming out in the thickness direction of the track 300. Therefore, during the use of the entire crack detection device 010, the restriction state of the track 300 on the rolling structure 100 is more stable, and the flexibility of use is improved. For example, in addition to supporting the rolling structure 100 at the bottom, the track 300 can also fix the rolling structure 100 at the top in a hanging manner.
[0062] In one embodiment, the bracket is made of aluminum alloy or alloy steel.
[0063] In this embodiment, the material of the bracket is limited, and aluminum alloy or alloy steel is used to meet the structural strength and achieve better weather resistance. Specifically, in order to achieve the design structural strength, the thickness of the horizontal plate 111 and the vertical plate 112 is limited according to actual conditions.
[0064] In summary, the cement engineering concrete structure crack detection device provided by the utility model combines multiple crack detection devices 010 according to the specific shape of the cement engineering concrete structure 020, so that the respective detection function parts 200 on the crack detection device 010 can detect cracks at corresponding positions; when two rolling structures 100 are connected in the length direction, extension in length can be achieved; adjacent rolling structures 100 can achieve shape transformation through the mutual connection between the vertical plate 112 and the horizontal plate 111; the vertical plate 112 serves as the fixing base of the roller assembly 120, and forms the basis for forming an angle connection between the two rolling structures 100.
