Description

Technical Field

[0001] This utility model relates to the field of crack detection technology, specifically a crack detection device for building engineering. Background Technology

[0002] Building cracks are cracks that occur in the structural components of a building. Depending on the material, they can be classified as concrete building cracks, brick masonry building cracks, new partition wall cracks, and cracks caused by different building materials. After cracks occur, workers need to measure and test them to take appropriate protective measures, which requires the use of testing equipment.

[0003] A search revealed that Chinese Patent Publication No. CN 220982134 U relates to the field of building engineering technology and discloses a crack detection device for building engineering. The device includes a base plate, wheels, and a crack detector. The wheels are mounted on the surface of the base plate, and an electric cylinder is fixedly mounted on the upper surface of the base plate. The moving end of the electric cylinder is rotatably connected to an I-shaped plate via a first rotating shaft. The moving end of the electric cylinder is equipped with a limiting mechanism connected to the I-shaped plate. The crack detector is located inside the I-shaped plate, and both sides of the crack detector are rotatably connected to the sides of the I-shaped plate via second rotating shafts. One end of the second rotating shaft extends to the outside of the I-shaped plate and is equipped with a locking mechanism. The locking mechanism includes a locking rod, a locking disc, and a spring. This invention allows for angular rotation of the crack detector, enabling it to be aligned with walls, roofs, or floors for crack detection, thus increasing the scope of application of the crack detector. It also provides protective storage for the crack detector, reducing the probability of damage.

[0004] The crack detection device in the aforementioned patent still has some shortcomings. In actual use, most existing building engineering crack detection devices require staff to hold the main unit of the detector and the connected planar transducer to the crack. When the crack is located on a high floor, it is difficult for the inspector to use and a ladder is required, which makes the operation relatively troublesome and reduces its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a building engineering crack detection device. It solves the problem that most existing building engineering crack detection devices require workers to hold the main unit of the detector and the connected planar transducer to the crack for detection. This method is difficult to use when the crack is located on a high floor slab, and a ladder is required for assistance, making the operation relatively cumbersome and reducing its practicality.

[0006] This utility model provides the following technical solution: a building engineering crack detection device, including a detection instrument main unit, two signal connectors symmetrically arranged at the top of the detection instrument main unit, an operation support component arranged on the outside of the detection instrument main unit, a detection adjustment component arranged on the operation support component, a signal connection line connected to each of the signal connectors, and a planar transducer connected to the end of the signal connection line.

[0007] The operating support assembly includes a mounting plate with a main unit slot. The main unit of the detector is inserted into the main unit slot. Two retraction grooves are symmetrically opened on the two side walls of the main unit slot. Each retraction groove is provided with an abutment plate. An abutment screw is rotatably connected to the side of the abutment plate. The end of the abutment screw is threaded through the inner wall of the retraction groove.

[0008] The detection and adjustment assembly includes a lifting connecting frame fixedly mounted on the side of the mounting plate. A lifting screw is rotatably mounted in the middle of the lifting connecting frame, and the bottom end of the lifting screw rotatably passes through the lifting connecting frame. A rotating handle is provided at the bottom end of the lifting screw. A lifting screw block is sleeved on the lifting screw. Two abutting push rods are symmetrically arranged on both sides of the top end of the lifting screw block. The top ends of the abutting push rods all pass through the top end of the lifting connecting frame. A top connecting plate is provided on the top of the lifting connecting frame. The bottom end of the top connecting plate is fixedly connected to the top ends of the abutting push rods. A fixing frame is fixed on the top connecting plate, and an installation slot is provided in the middle of the fixing frame.

[0009] Preferred technical solution 1: The planar transducers are all inserted into the mounting slots, and the top wall of the mounting slots is provided with a fixing contact plate.

[0010] Preferred technical solution 2: The top end of the fixed contact plate is symmetrically rotatably connected to two fixing screws, and the top ends of the fixing screws are threaded through the fixed frame.

[0011] Preferred technical solution three: The front side of the host slot is open.

[0012] This solution ensures that the mounting plate does not obstruct the side display screen of the main unit of the detector, making it easier for users to observe and operate the main unit.

[0013] Preferred technical solution four: The end of the top connecting plate extends to the side of the top of the lifting connecting frame.

[0014] This solution allows the planar transducer to extend to the side of the lifting connection frame, making it easier for the planar transducer to fit into the wall crack, thus facilitating subsequent crack detection.

[0015] Preferred technical solution five: Two support rings are symmetrically arranged on the side of the top end of the top connecting plate.

[0016] This design allows the signal connection lines connected to the planar transducer on the top connecting plate to be limited by the support ring, preventing the signal connection lines from getting tangled.

[0017] Compared with the prior art, this utility model provides a crack detection device for building engineering, which has the following beneficial effects:

[0018] (1) This utility model inserts the main unit of the detector into the mounting slot in the operating support assembly, while the planar transducer is fixed in the mounting slot. When the user needs to detect cracks at high places on the wall, the user only needs to rotate the lifting screw. The lifting screw will push the top connecting plate upward through the lifting screw block and the abutment push rod, which will drive the planar transducer fixed on the mounting slot to rise to the crack. This greatly expands the crack detection range of the operator, making the operation more convenient, easy to carry, and more convenient for the user to use. Attached Figure Description

[0026] Please see Figure 1-4 ,

[0027] Example 1: A crack detection device for building engineering includes a main unit 1. Two signal connectors 2 are symmetrically arranged on the top of the main unit 1. An operation support component 3 is arranged on the outside of the main unit 1. A detection adjustment component 4 is arranged on the operation support component 3. Each signal connector 2 is connected to a signal connection line 5. A planar transducer 6 is connected to the end of the signal connection line 5.

[0028] The operation support assembly 3 includes a mounting plate 301, on which a main unit mounting slot 302 is provided. The main unit 1 of the detector is inserted into the main unit mounting slot 302. Two retraction grooves 303 are symmetrically provided on the two side walls of the main unit mounting slot 302. Each retraction groove 303 is provided with an abutment plate 304. An abutment screw 305 is rotatably connected to the side of the abutment plate 304. The end of the abutment screw 305 is threaded through the inner wall of the retraction groove 303.

[0029] The detection and adjustment assembly 4 includes a lifting connecting frame 401 fixedly mounted on the side of the mounting plate 301. A lifting screw 402 is rotatably mounted in the middle of the lifting connecting frame 401, and the bottom end of the lifting screw 402 rotatably passes through the lifting connecting frame 401. A rotating handle 403 is provided at the bottom end of the lifting screw 402. A lifting screw block 404 is sleeved on the lifting screw 402. Two abutting push rods 405 are symmetrically arranged on both sides of the top end of the lifting screw block 404. The top ends of the abutting push rods 405 all pass through the top end of the lifting connecting frame 401. A top connecting plate 406 is provided on the top of the frame 401. The bottom end of the top connecting plate 406 is fixedly connected to the top end of the push rod 405. A fixed frame 407 is fixed on the top connecting plate 406. An installation slot 408 is provided in the middle of the fixed frame 407. The planar transducers 6 are all inserted into the installation slot 408. A fixed abutment plate 409 is provided on the top wall of the installation slot 408. Two fixed screws 410 are symmetrically rotatably connected to the top end of the fixed abutment plate 409. The top ends of the fixed screws 410 are threaded through the fixed frame 407.

[0030] Example 2: The difference between this example and Example 1 is that the front side of the host slot 302 is open.

[0031] This ensures that the mounting plate 301 does not obstruct the side display screen of the detector host 1, making it easier for the user to observe and operate the detector host 1.

[0032] Example 3: The difference between this example and Example 1 is that the end of the top connecting plate 406 extends to the side of the top of the lifting connecting frame 401.

[0033] This allows the planar transducer 6 to extend to the side of the lifting connection frame 401, making it easier for the planar transducer 6 to fit into the wall crack, thus facilitating subsequent crack detection.

[0034] Example 4: The difference between this example and Example 1 is that two support rings are symmetrically arranged on the side of the top of the top connecting plate 406.

[0035] This ensures that the signal connection lines 5 connected to the planar transducer 6 on the top connecting plate 406 are limited by the support ring to prevent the signal connection lines 5 from getting tangled.

[0036] In this embodiment, since most existing building crack detection devices are used in practice by staff who hold the main unit of the detector and the connected planar transducer to the crack, this method is difficult for the inspectors to use when the crack is located on a high floor slab, and a ladder is required for assistance, making the operation relatively troublesome and reducing its practicality.

[0037] In summary, in practical implementation, when a user needs to inspect cracks at higher points on a building floor slab, the user can insert the main unit 1 of the detector into the main unit mounting slot 302 in the operating support assembly 3. By rotating the abutment screw 305, the abutment screw 305 pushes the abutment clamp 304 to abut and fix the two sides of the main unit 1 of the detector. The planar transducer 6 is inserted into the mounting slot 408. The user can adjust the distance between the two planar transducers 6 according to the actual crack situation. After adjusting the distance, the two planar transducers 6 are then rotated by rotating the fixing screw 410, which pushes the fixing abutment plate 409 to press the top of the planar transducer 6, ensuring the stability of the planar transducer 6.

[0038] Next, the user can rotate the lifting screw 402, which is rotatably mounted in the middle of the lifting connecting frame 401, so that the lifting screw 402 can push the abutment push rod 405 upward through the lifting screw block 404. The top connecting plate 406 at the top of the abutment push rod 405 is provided with a mounting slot 408, and a planar transducer 6 is fixed in the mounting slot 408. This allows the user to adjust the height of the planar transducer 6 appropriately, greatly expanding the user's wall crack detection range. In addition, the entire device is made of high-strength plastic material to ensure the overall portability of the device, making it more convenient for users to carry and use for detection when going out. It is easy to operate and convenient for users to use.
