Abstract
Description
Technical Field
[0001] This application relates to the field of construction engineering technology, specifically to a crack detection device for construction projects. Background Technology
[0002] Cracks in steel structures are a common problem in construction projects. They not only affect the safety of the structure but may also shorten its service life. The causes of cracks in steel structures include cold cracks, which mainly occur when the welded joint cools down to below the martensitic transformation temperature and are common within a certain period after welding; hot cracks, which occur at high temperatures and usually appear inside the weld, and are related to metallurgical and mechanical factors; and stress cracks, which are caused by excessive construction loads, structural stress concentration, or improper control of the protective layer thickness.
[0003] Steel structures require regular inspections to ensure that they do not cause property damage in the event of cracks. Ultrasonic flaw detectors are used to inspect the surface of the steel structure. The ultrasonic flaw detector detects the echoes generated when ultrasonic waves encounter defects, which are received by a receiver and converted into electrical signals. By analyzing these signals, the location, size, and shape of the defects can be determined, thus enabling the inspection of the steel structure.
[0004] Because steel structures are the main structural element, they are generally quite tall. When using ultrasonic flaw detectors, personnel need to hold the probe close to the surface of the steel structure to transmit signals. When inspecting parts of the steel structure located at higher elevations, personnel need to use climbing equipment to move to those areas. This method is inconvenient when dealing with areas where climbing equipment cannot easily access, making it difficult to inspect those high-altitude parts of the steel structure. Utility Model Content
[0005] The purpose of this application is to provide a crack detection device for construction projects, in order to solve the problem mentioned in the background art that, because steel structures are the main structures, they are generally quite tall. During the ultrasonic flaw detector inspection process, personnel need to hold the probe and place it against the surface of the steel structure to transmit signals. When it is necessary to inspect the high parts of the steel structure, personnel need to use climbing equipment to move to the high parts of the steel structure for inspection. This method is inconvenient when dealing with areas where climbing equipment is inaccessible, making it difficult to inspect the high parts of the steel structure.
[0006] To achieve the above objectives, this application provides the following technical solution: a crack detection device for construction projects, comprising: a crack detection device body, a position adjustment mechanism, and a drive displacement mechanism. The crack detection device body includes an ultrasonic flaw detector body and an ultrasonic probe connected to the ultrasonic flaw detector body via a cable. The position adjustment mechanism is located on the outside of the ultrasonic probe and includes a fixed block located on the outside of the ultrasonic probe. The drive displacement mechanism is located on the outer wall of the fixed block and includes a second guide rod welded to the upper and lower sides of the fixed block, a limiting plate slidably connected to both ends of the second guide rod, a bidirectional cylinder fixed to the back of the fixed block, the output ends of the bidirectional cylinder being connected to the limiting plate, a first roller fixed to the inner wall of the limiting plate, and a second roller rotatably connected to the inside of the limiting plate via a shaft.

[0012] Preferably, the position adjustment mechanism further includes a threaded rod whose two ends are engaged and fixed in the bearings of the fixed block.
[0013] By adopting the above technical solution, it is possible to fix the device in place without affecting its rotational operation.
[0014] Preferably, the position adjustment mechanism further includes a first motor fixed on the outer wall of the fixed block, and the output end of the first motor is connected to one end of the threaded rod.
[0015] By adopting the above technical solution, the first motor can drive the structure connected to the output end to rotate stably.
[0016] Preferably, the position adjustment mechanism further includes a mounting block slidably connected to the first guide rod, wherein an ultrasonic probe is fixedly disposed inside the mounting block, and a threaded through hole is provided on the mounting block.

[0018] Preferably, the threaded rod is threaded inside the threaded through hole of the mounting block.
[0019] By adopting the above technical solution, the rotation of the threaded rod can drive the connected structure to rotate and shift.
[0020] In summary, this application has the following beneficial effects: By providing a position adjustment mechanism and a drive displacement mechanism, the drive displacement mechanism can be fixed to both sides of the steel structure by clamping according to the size of the steel structure. At this time, the ultrasonic probe fixed inside the position adjustment mechanism is driven by the rotation of the rollers to achieve height movement on the outer wall of the steel structure. Thus, it is possible to quickly detect high parts of the steel structure without the aid of climbing equipment. Furthermore, the position adjustment mechanism can drive the ultrasonic probe to move horizontally back and forth simultaneously during the vertical displacement, thereby providing detection of multiple points on the outer surface of the steel structure and improving the accuracy of the detection data.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.
[0028] Example 1
[0029] Please see Figures 1-4 This embodiment provides a technical solution: a crack detection device for construction projects, comprising: an ultrasonic flaw detector body 1, an ultrasonic probe 2, a position adjustment mechanism 3, and a drive displacement mechanism 4;
[0030] The crack detection device mainly includes an ultrasonic flaw detector body 1 and an ultrasonic probe 2 connected to the ultrasonic flaw detector body 1 via a cable. The echo generated by the ultrasonic waves encountering the defect is received by the receiver and converted into an electrical signal. By analyzing these signals, the location, size and shape of the defect can be determined, thereby realizing the detection of the steel structure. The above is the existing technology and will not be described in detail below.
[0031] The position adjustment mechanism 3 is located on the outside of the ultrasonic probe 2. The position adjustment mechanism 3 includes a fixing block 301 located on the outside of the ultrasonic probe 2. Through circular holes are opened on both sides of the inner wall of the fixing block 301, and a bearing is installed inside the through circular hole of the fixing block 301.
[0032] The driving displacement mechanism 4 is installed on the outer wall of the fixed block 301. The driving displacement mechanism 4 includes a second guide rod 401 welded to the upper and lower sides of the fixed block 301, a limiting plate 402 slidably connected to both ends of the second guide rod 401, a bidirectional cylinder 403 fixed to the back of the fixed block 301, the output ends of the bidirectional cylinder 403 on both sides being connected to the limiting plate 402, a first roller 404 fixed to the inner wall of the limiting plate 402, and a second roller 405 rotatably connected to the inside of the limiting plate 402 via a shaft. The first roller 404 and the second roller 405 are distributed at a 90° angle.
[0033] The drive displacement mechanism 4 also includes a second motor 406 fixed on the outer wall of the limiting plate 402, a first pulley 407 set on the shaft of the second roller 405, a second pulley 408 fixed on the output shaft of the second motor 406, and a wide belt 409 with its two ends respectively sleeved on the first pulley 407 and the second pulley 408.
[0034] The ultrasonic flaw detector body 1 and ultrasonic probe 2 are connected by a cable for signal transmission. When it is necessary to move the ultrasonic probe 2 vertically against the surface of the steel structure, the bidirectional cylinder 403 is activated. The bidirectional cylinder 403 drives the limiting plate 402 to move horizontally on the second guide rod 401, so that the first roller 404 and the second roller 405 on the limiting plate 402 can press against both sides of the surface of the steel structure. At this time, the second motor 406 is activated. Since the first pulley 407 and the second pulley 408 are connected by a wide belt 409, the second motor 406 drives the second pulley 408 to rotate, and at the same time drives the second roller 405 connected to the first pulley 407 to rotate. At this time, the second roller 405 is against both sides of the outer surface of the steel structure, thus achieving vertical movement. This drives the position adjustment mechanism 3 of the fixed ultrasonic probe 2 to move vertically as well. When it is necessary to move the ultrasonic probe 2 horizontally, the position adjustment mechanism 3 can be used quickly.
[0035] Example 2
[0036] Please see Figures 1-4 This embodiment provides a technical solution: a construction engineering crack detection device, including: a first guide rod 302, a threaded rod 303, a first motor 304, and a mounting block 305;
[0037] A first guide rod 302 is welded to the inner wall of the fixed block 301. A threaded rod 303 is engaged and fixed at both ends in the bearings of the fixed block 301. A first motor 304 is fixed to the outer wall of the fixed block 301, and the output end of the first motor 304 is connected to one end of the threaded rod 303. A mounting block 305 is slidably connected to the first guide rod 302. An ultrasonic probe 2 is fixed inside the mounting block 305, and a threaded through hole is opened on the mounting block 305. The threaded rod 303 is threadedly connected to the inside of the threaded through hole of the mounting block 305.
[0038] When it is necessary to move the ultrasonic probe 2 horizontally, it can be done quickly through the position adjustment mechanism 3. The first motor 304 on the fixed block 301 is started. During the operation of the first motor 304, the threaded rod 303 connected to the output end will rotate. At this time, during the rotation of the threaded rod 303, the threaded mounting block 305 connected to the thread will move steadily in the horizontal direction through the first guide rod 302, thereby providing the ultrasonic probe 2 fixed on the mounting block 305 to move in the horizontal direction together.
[0039] The implementation principle of the construction engineering crack detection device of this application is as follows:
[0040] First, connect the main body 1 of the ultrasonic flaw detector and the ultrasonic probe 2 by plugging in a cable to transmit the signal.
[0041] Secondly, when it is necessary to move the ultrasonic probe 2 vertically against the surface of the steel structure, the bidirectional cylinder 403 is activated. The bidirectional cylinder 403 drives the limiting plate 402 to move horizontally on the second guide rod 401, so that the first roller 404 and the second roller 405 on the limiting plate 402 can be pressed against both sides of the surface of the steel structure. At this time, the second motor 406 is activated. Since the first pulley 407 and the second pulley 408 are connected by a wide belt 409, the second motor 406 drives the second pulley 408 to rotate, and at the same time drives the second roller 405 connected to the first pulley 407 to rotate. At this time, the second roller 405 is pressed against both sides of the outer surface of the steel structure, thereby achieving vertical movement. This will drive the position adjustment mechanism 3 of the fixed ultrasonic probe 2 to move vertically as well.
[0042] Finally, when it is necessary to move the ultrasonic probe 2 horizontally, this can be done quickly through the position adjustment mechanism 3. The first motor 304 on the fixed block 301 is started. During the operation of the first motor 304, the threaded rod 303 connected to the output end will rotate. At this time, during the rotation of the threaded rod 303, the threaded mounting block 305 connected to the thread will move steadily in the horizontal direction through the first guide rod 302, thereby providing the ultrasonic probe 2 fixed on the mounting block 305 to move in the horizontal direction together.
[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
