Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to an auxiliary device for phased array detection of concrete in confined spaces. Background Technology

[0002] Phased array ultrasonic testing technology is increasingly widely used in the detection of internal defects (such as cracks, voids, and loose areas) in concrete structures due to its advantages such as high detection efficiency and intuitive imaging. Existing phased array testing equipment is usually large and heavy, requiring the operator to hold the testing device and press it on the concrete surface to perform the test, and manually press the record button on the instrument to save the data.

[0003] However, in actual engineering testing, one often encounters confined spaces and gaps where space is extremely limited, making it difficult for personnel to enter or maintain a stable and comfortable testing posture. Forcing entry is not only inefficient and prone to missed detections, but also poses safety hazards and makes it difficult to ensure proper coupling between the probe and the concrete surface and the correctness of the scanning path.

[0004] Therefore, there is an urgent need for an auxiliary device that can help operators safely and stably send phased array probes into confined spaces and remotely control the instrument's recording function. Utility Model Content

[0005] The present invention aims to solve the problem that existing phased array concrete detection devices cannot perform safe and stable detection in confined spaces.

[0006] This utility model provides an auxiliary device for phased array testing of concrete in confined spaces. The testing device includes a testing surface and a display screen opposite to the testing surface. Handles symmetrically distributed on both sides of the display screen are mounted on the testing device, and each handle has a switch button. The auxiliary device includes two sets of control mechanisms respectively mounted on the two handles. Each control mechanism includes a fixed rod, a movable rod, and a lifting rod. The fixed rod is directly or indirectly fixedly connected to the handle. A rotating component connects the movable rod to the fixed rod, allowing the movable rod to rotate about the fixed rod as a rotation axis. A roller is mounted on the movable rod. The lifting rod is hinged to the fixed rod. A pressure rod located on the upper part of the testing device connects the lifting rods of the two sets of control mechanisms. A pull-wire mechanism for driving the switch button is mounted on the switch button.

[0007] This utility model provides an auxiliary device for phased array detection of concrete in confined spaces, which, compared with the prior art, has the following beneficial effects, but is not limited to: This auxiliary device is used with existing testing equipment. In operation, the movable rods in the two sets of control mechanisms are adjusted so that they rotate around the fixed rod via rotating parts until they are directly below the fixed rod, ensuring the testing device is suspended. Then, the rollers on the movable rods move the testing device to the narrow space to be tested. Next, the two movable rods are flipped outwards, causing the rollers to move to both sides. During this process, the testing device descends to the concrete testing surface. Then, the lifting rod is raised, rotating around its hinge point with the fixed rod. At this time, the other end of the lifting rod (the end closer to the testing mechanism) moves downwards, causing the pressure rod to move downwards. The pressure bar applies downward pressure to the upper surface (display screen) of the testing mechanism, ensuring good acoustic coupling between the testing probe on the lower surface (testing surface) and the concrete surface. Finally, the switch button is activated via a pull-wire mechanism, enabling testing and data acquisition. This auxiliary device allows for convenient and safe placement and stabilization of the testing device in confined spaces or crevices where direct human operation is difficult, achieving good coupling between the testing probe and the concrete surface, standardizing the scanning path, and remotely triggering the switch button. This improves testing efficiency and safety, and reduces the risk of missed detections.

[0008] Furthermore, the detection device is located at one end of the fixed rod, the movable rod, and the lifting rod.

[0009] Furthermore, a connector is provided between the handle and the fixed rod.

[0010] Furthermore, the connector includes a support rod and a connecting sleeve fixedly connected to one end of the support rod, the other end of the support rod being fixedly connected to a fixed rod, and the connecting sleeve being detachably fixedly fitted onto the handle.

[0011] Furthermore, the rotating component includes a connecting rod and a connecting sleeve fixedly connected to one end of the connecting rod, the other end of the connecting rod being fixedly connected to the movable rod, and the connecting sleeve being rotatably sleeved on the fixed rod.

[0012] Furthermore, a guide mechanism is provided between the connecting sleeve and the fixed rod, the guide mechanism being used to ensure that the connecting sleeve rotates only on the fixed rod.

[0013] Furthermore, the fixed rod, movable rod, and lifting rod are all telescopic rods with adjustable length.

[0014] Furthermore, the pull-cord mechanism includes a sleeve fixedly mounted on the handle, the switch button is located inside the sleeve, a control block located at one end of the switch button is installed inside the sleeve, a spring is connected between the end of the control block away from the switch button and the sleeve, the extension and contraction direction of the spring is the same as the movement direction of the switch button; a pull cord is connected to the control block for pulling the control block toward the switch button.

[0028] Please see Figure 1 This utility model discloses an auxiliary device for phased array concrete detection in confined spaces. The device includes a detection device 100, which comprises a detection surface and a display screen opposite to the detection surface. Handles 101 symmetrically distributed on both sides of the display screen are mounted on the detection device 100, and switch buttons 102 are mounted on the handles 101. The auxiliary device includes two sets of control mechanisms respectively mounted on the two handles 101. Each control mechanism includes a fixed rod 200, a movable rod 300, and a lifting rod 400. The fixed rod 200 is directly or indirectly fixedly connected to the handle 101. A rotating component 500 is connected between the movable rod 300 and the fixed rod 200, allowing the movable rod 300 to rotate about the fixed rod 200 as a rotation axis. A roller 301 is mounted on the movable rod 300. The lifting rod 400 is hinged to the fixed rod 200. A pressure rod 700 located on the upper part of the detection device 100 is connected between the lifting rods 400 in the two sets of control mechanisms. A pull-wire mechanism 800 for driving the switch button 102 is mounted on the switch button 102.

[0029] In this embodiment, the auxiliary device is used with an existing detection device 100. During use, the movable rods 300 in the two sets of control mechanisms are adjusted so that they rotate around the fixed rod 200 via the rotating member 500 until they are directly below the fixed rod 200, ensuring that the detection device 100 is suspended. Then, the rollers 301 on the movable rods 300 move the detection device 100 to the narrow space to be detected. Next, the two movable rods 300 are flipped outwards, causing the rollers 301 to move to both sides. During this process, the detection device 100 descends to the concrete detection surface. Then, the lifting rod 400 is raised, causing it to rotate around the hinge point with the fixed rod 200. At this time, the other end of the lifting rod 400 (closer to the detection mechanism 100)... One end moves downward, causing the pressure rod 700 to move downward, so that the pressure rod 700 applies downward pressure to the upper surface (display screen) of the detection mechanism 100, ensuring that the detection probe on the lower surface (detection surface) of the detection mechanism 100 achieves a good acoustic coupling state with the concrete surface; finally, the switch button 102 is opened by the pull wire mechanism 800, so that detection and data acquisition can be performed; it can be seen that, through this auxiliary device, the detection device 100 can be conveniently and safely sent into and stabilized in a narrow space or gap that is difficult for personnel to operate directly, achieving good coupling between the detection probe and the concrete surface, standardizing the scanning path, and remotely triggering the switch button 102, thereby improving detection efficiency and safety and reducing the risk of missed detection.

[0030] Please note that you should refer to [link / reference]. Figure 2 The detection device 100 is a phased array ultrasonic testing device in the prior art. The handle 101 and the switch button 102 on it are inherent structures. The position and structure of the handle 101 and the switch button 102 are carried by the detection device 100 itself. The handle 101 is U-shaped, and the two handles 101 are located at the left and right ends of the detection device 100 respectively, and are symmetrical about the detection device 100. The switch button 102 is installed on the rear side of one of the handles 101, and its movement direction is the front and back direction. For example, in this embodiment, the model of the detection device 100 is: A1040 MIRA 3D ultrasonic tomography scanner.

[0031] Meanwhile, after the switch button 102 is triggered, the testing personnel can perform operations such as data saving and naming through a mobile phone or other terminal that is connected to the testing device 100 via WiFi.

[0032] Optionally, the detection device 100 is located at one end of the fixed rod 200, the movable rod 300, and the lifting rod 400.

[0033] In this embodiment, the fixed rod 200, the movable rod 300, and the lifting rod 400 have the same overall length and are aligned at their front and rear ends. The detection device 100 is located at the rear end of the fixed rod 200, the movable rod 300, and the lifting rod 400 to facilitate insertion into narrow spaces. Anti-slip sleeves 900 are installed at the front ends of the fixed rod 200, the movable rod 300, and the lifting rod 400 to enhance the friction during operation and prevent slippage.

[0034] Optionally, a connector 600 is provided between the handle 101 and the fixed rod 200.

[0035] In this embodiment, the handle 101 and the fixed rod 200 are indirectly fixedly connected by the connector 600, which can keep the relative position between the fixed rod 200 and the detection device 100 stationary.

[0036] Optionally, the connector 600 includes a support rod 602 and a connecting sleeve 601 fixedly connected to one end of the support rod 602. The other end of the support rod 602 is fixedly connected to the fixing rod 200. The connecting sleeve 601 is detachably and fixedly sleeved on the handle 101.

[0037] In this embodiment, the connecting sleeve 601 is open-ended, and a connecting bolt is provided at the open end of the connecting sleeve 601. The open-ended connecting sleeve 601 is fitted onto the handle 101, and then the open end is fixedly connected with the bolt, so that the connecting sleeve 601 can be fixedly installed on the handle 101. Similarly, by loosening the bolt, the connecting sleeve 601 can be removed, so as to achieve a detachable connection between the connecting sleeve 601 and the handle 101, thereby allowing the fixing rod 200 and the entire auxiliary device to be mounted and dismounted onto the detection device 100.

[0038] Optionally, the rotating component 500 includes a connecting rod 502 and a rotating sleeve 501 fixedly connected to one end of the connecting rod 502. The other end of the connecting rod 502 is fixedly connected to the movable rod 300, and the rotating sleeve 501 is rotatably sleeved on the fixed rod 200.

[0039] In this embodiment, since the rotating sleeve 501 and the fixed rod 200 are rotatably connected, the movable rod 300 can move in a circle around the fixed rod 200 as the central axis. When the movable rod 300 moves in a circle to below the fixed rod 200, the lower side of the detection device 100 needs to be suspended off the ground to avoid friction with the ground during the movement.

[0040] Optionally, a guide mechanism is provided between the rotating sleeve 501 and the fixed rod 200, the guide mechanism being used to ensure that the rotating sleeve 501 rotates only on the fixed rod 200.

[0041] In this embodiment, the guide mechanism includes an annular rail formed on the fixed rod 200 and an annular protrusion disposed on the inner ring of the rotating sleeve 501. The annular protrusion is movably embedded in the annular rail, ensuring that the rotating sleeve 501 can only rotate on the fixed rod 200 and will not move back and forth, thereby improving the stability of the movable rod 300 when it is flipped.

[0042] Optionally, the fixed rod 200, the movable rod 300, and the lifting rod 400 are all telescopic rods with adjustable length.

[0043] In this embodiment, the fixed rod 200, the movable rod 300, and the lifting rod 400 are all configured as multi-section sleeve structures, and their lengths can be locked by snap rings or knobs. Their lengths can meet the detection requirements of common narrow spaces, and they have sufficient rigidity and stability to ensure that the probe tip does not shake excessively, thus affecting the coupling effect and scanning accuracy.

[0044] Optionally, please refer to Figure 3 The pull-cord mechanism 800 includes a sleeve 801 fixedly mounted on the handle 101. The switch button 102 is located inside the sleeve 801. A control block 802 located at one end of the switch button 102 is installed inside the sleeve 801. A spring 803 is connected between the end of the control block 802 away from the switch button 102 and the sleeve 801. The extension and retraction direction of the spring 803 is the same as the movement direction of the switch button 102. A pull cord 804 is connected to the control block 802 for pulling the control block 802 toward the switch button 102.

[0045] In this embodiment, pulling the pull cord 804 can drive the control block 802 to move toward the switch button 102, thereby turning on the detection device 100; when the pull cord 804 is released, the control block 802 resets under the elastic force of the spring 803; in this way, remote control of the switch button 102 can be realized.

[0046] Optionally, the sleeve 801 has a channel 805 on its body, the extension direction of the channel 805 is parallel to the movement direction of the switch button 102, and the pull rope 804 passes through the channel 805.

[0047] In this embodiment, the pull rope 804 is threaded through the channel 805, which allows the movement of the pull rope 804 to be unrestricted and ensures the traction effect on the control block 802.

[0048] Optionally, the lifting rod 400 and the fixing rod 200 are hinged by a pin 401.

[0049] In this embodiment, a fixed-point hinge is achieved by means of pin 401. When the front end of the lifting rod 400 is lifted upward, the lifting rod 400 rotates around pin 401, causing its rear end to move downward, thereby realizing the lifting and lowering control of the rear end of the lifting rod 400.

[0050] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
