Description

Technical Field

[0001] This utility model relates to the field of building crack detection, specifically to a user-friendly building crack detection device. Background Technology

[0002] Building crack detection is a process of systematically investigating and analyzing cracks on or inside a building using specialized equipment and technology. Through non-destructive testing methods such as ultrasound, laser, and electromagnetic induction, the location of cracks is accurately determined, their width and depth are measured, and the impact of cracks on building safety is assessed in conjunction with structural mechanics principles. Ultimately, this provides a scientific basis for developing repair and reinforcement plans or long-term monitoring strategies, and is a key link in ensuring the durability and safety of building structures.

[0003] The building crack detector emits specific signals to the crack area through a built-in transmitting device (such as an ultrasonic probe or a laser emitter). When the signal encounters the crack, it will be reflected, refracted, or its shape will change (such as the ultrasonic wave reflection time being prolonged, or the laser line being displaced due to the crack width). After the receiving device captures these changing signals, it processes them through internal algorithms to calculate parameters such as the depth, width, and location of the crack. Finally, the detection results are displayed on the screen in real time, realizing fast and accurate non-destructive testing.

[0004] In the existing technology, when encountering high positions during crack detection, ladders or other climbing devices are needed to place the detection head of the device. Using this method will affect the efficiency of subsequent detection work, for example, it is inconvenient to adjust the device and multiple people need to work together simultaneously. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an easy-to-use building crack detection device. This device systematically solves the deficiencies of traditional crack detection devices in terms of operational flexibility, detection range, stability, durability and data reliability by combining mechanical structural innovation (such as adjustable extension frame and double threaded screw drive) and auxiliary function design (such as level and triangular pressure plate), and significantly improves the efficiency and accuracy of building crack detection.

[0006] The objective of this utility model is achieved through the following technical solution: An easy-to-use building crack detection device includes a detector, an extension frame, an adjusting component, and a triangular pressure plate. The detector has a fixed base at its upper end, and two detachable connectors at its upper output ends. Each connector includes a second connecting line connected to the fixed base. Second handles for support are connected to the left and right ends of the fixed base, and a triangular pressure plate is connected to the rear end of each handle. A telescopic extension frame is connected to the upper end of the fixed base, and an adjusting component is located at its upper end. The adjusting component includes a limiting bracket mounted on a connecting plate on the extension frame. A double-threaded screw with two symmetrical threaded grooves is rotatably mounted on the limiting bracket. A threaded rod sleeve is threaded onto the double-threaded screw, and a probe is mounted on the threaded rod sleeve. A right-angle converter is connected to the left end of the double-threaded screw, and the other rotating output end of the right-angle converter is connected to the extension frame. A scale is connected to the lower end of the connecting plate, and a guide head is connected to the threaded rod sleeve, with the arrow of the guide head pointing towards the scale.

[0007] In one optional implementation, the two upper output ends of the detector are connected to a first connecting line, the outer wall of the first connecting line is provided with a protective spring, the upper end of the first connecting line is connected to a connecting socket, and the upper end of the connecting socket is connected to a screw ring.

[0008] In one alternative implementation, the connector includes a fixed screw sleeve threaded onto a screw ring, and a second connecting wire passes through the fixed screw sleeve and is inserted into the connecting socket.

[0009] In one alternative implementation, the inner layer of the extension frame is fitted with two extension layers, and the upper and lower ends of the connecting plate are provided with a first groove.

[0010] In one alternative implementation, a fourth connecting line is connected to the lower end of the lead screw sleeve, the fourth connecting line is connected to the second connecting line, and the fourth connecting line passes through the first groove and is placed in the extension frame.

[0011] In one optional implementation, a connecting frame is provided at the upper end of the lead screw sleeve, a connecting sleeve is connected to the front end of the connecting frame, and a third connecting line is connected to the rear end of the probe head, with the third connecting line inserted into the connecting sleeve.

[0012] In one alternative implementation, the outer wall of the probe head is provided with two fixing frames, which are fixedly connected to the connecting frame by bolts, and the guide head is fixed to the front end of the connecting frame.

[0013] In one alternative implementation, the front and rear ends of the lead screw sleeve are fitted with the front and rear ends of the inner wall of the limiting frame.

[0014] In one alternative implementation, a level is provided at the front end of the fixed base, and the front ends of the two second handles are connected to the first handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The height of the device can be adjusted by the extension frame to solve the problem that normal human hands cannot place the detection position at a high position. When the extendable frame rotates, the adjustment component is driven by the limit frame to adjust the distance between the two probes. The height-increasing extension component can be removed by the detachable connector. The above solves the problems of inconvenient adjustment of the probe position, difficulty in achieving accurate multi-point measurement and limited detection height, and difficulty in reaching high or deep cracks.

[0016] 2. The probe head can be moved closer or further away synchronously by the double-threaded screw and the lead screw sleeve. The design of the extension frame and right-angle converter allows the probe head to rotate and adjust the angle in the horizontal direction to adapt to changes in crack direction.

[0017] 3. The movement of the probe head drives the movement of the scale head. The arrow on the scale head points to the numbers on the scale, allowing for intuitive adjustment of the two probe heads. Attached Figure Description

The height-increasing extension component can be removed by the detachable connector. The above solves the problems of inconvenient adjustment of the probe position, difficulty in achieving accurate multi-point measurement, and limited detection height, making it difficult to reach high or deep cracks.

[0025] Please refer to Figures 1-4 In a preferred embodiment of this utility model, the two output ends of the upper end of the detector 1 are connected to a first connecting line 101. The outer wall of the first connecting line 101 is provided with a protective spring 102. The upper end of the first connecting line 101 is connected to a connecting socket 103. The upper end of the connecting socket 103 is connected to a screw ring 104. The connector includes a fixing sleeve 106 threaded onto the screw ring 104. The second connecting line 105 passes through the fixing sleeve 106 and is then inserted into the connecting socket 103. After the second connecting line 105 is inserted into the connecting socket 103, the fixing sleeve 106 is rotated so that the fixing sleeve 106 is threaded onto the screw ring 104. The inner layer of the extension frame 3 is provided with two extension layers. The upper and lower ends of the connecting plate 301 are provided with a first groove 302. The front end of the fixed base 2 is provided with a level 201. The front ends of the two second handles 203 are connected to the first handle 202.

[0026] Please refer to Figures 3-6In a preferred embodiment of this utility model, a fourth connecting line 409 is connected to the lower end of the lead screw sleeve 402. The fourth connecting line 409 is connected to the second connecting line 105. The fourth connecting line 409 passes through the first groove 302 and is placed in the extension frame 3. A connecting frame 403 is provided at the upper end of the lead screw sleeve 402. A connecting sleeve 406 is connected to the front end of the connecting frame 403. A third connecting line 407 is connected to the rear end of the probe head 404. The third connecting line 407 is inserted into the connecting sleeve 406. Two... A fixed frame 405 is fixedly connected to a connecting frame 403 via bolts. The guide head 408 is fixed to the front end of the connecting frame 403. The front and rear ends of the screw sleeve 402 are in contact with the front and rear ends of the inner wall of the limiting frame 4. The probe head 404 moves synchronously closer or further away through the threaded engagement of the double threaded screw 401 and the screw sleeve 402. The design of the extension frame 501 and the right angle converter 5 allows the probe head 404 to rotate and adjust its angle in the horizontal direction to adapt to changes in crack orientation.

[0027] First, insert the second connecting wire 105 on the connector on the fixed base 2 into the connecting socket 103. Then, by rotating the fixing sleeve 106, it is threaded onto the screw ring 104 to connect the two second connecting wires 105 to the first connecting wire 101. The spring 102 is used to protect the first connecting wire 101. By pulling out the inner liner of the extension frame 3, the extension frame 3 can be extended. Then, the extension frame 501 is stretched synchronously. During the stretching of the extension frame 3, the fourth connecting wire 409 inside the extension frame 3 will also be straightened, ensuring that the two probes 404 and the two second connecting wires 105 can be connected normally.

[0028] During use, by rotating the extension frame 501, the double-threaded screw 401 on the limit frame 4 can be rotated, so that the two threaded sleeves 402 move synchronously on the double-threaded screw 401, moving closer and further away from each other, thereby changing the position of the two probes 404. Through multi-point measurement, random errors are eliminated, the full picture of the crack morphology is obtained, the reliability of the data is verified, and the needs of complex structure detection are met.

[0029] During placement, the rear end of the device is pressed against the wall, so that the rear end of the triangular pressure plate 204 is in contact with the wall surface. The horizontal position of the fixed seat 2 can be adjusted by using the level 201.

[0030] Through the above steps, the height of the device can be adjusted by the extension frame 3 to solve the problem that normal human hands cannot place the detection position at a higher level. When the extendable extension frame 501 rotates, the adjustment component is driven by the limit frame 4 to adjust the distance between the two probes 404. The height-increasing extension component can be removed by the detachable connector. The above steps solve the problems of inconvenient adjustment of the probe position, difficulty in achieving accurate multi-point measurement, and limited detection height, making it difficult to reach high or deep cracks.

[0031] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0032] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
