Description
Technical Field
[0001] This invention belongs to the field of building engineering technology, and in particular relates to a rapid crack detection system for building engineering. Background Technology
[0002] The crack width tester has a measurement range of 0.01 mm to 2.00 mm, a reading accuracy of 0.005 mm, and a magnification of 40 times. After use, the crack width tester should be placed in its packaging sleeve or instrument box in a timely manner to prevent dust from entering the instrument. The instrument should be maintained regularly. After a period of use, it should be wiped and cleaned, but the assembly relationship of the various parts and the whole machine should not be changed.
[0003] The prior art can be referenced in Chinese invention patent with authorization announcement number (CN110528371B), which discloses a road crack detector, including a detector housing, an electronic display screen, operation buttons, a data cable, and a detection head. It also includes an extension device, which comprises a movable base, multiple rollers mounted on the bottom of the movable base, a horizontal plate that slides vertically, a fixing mechanism mounted on the top of the horizontal plate for fixing the detection head, and an extension mechanism mounted on the top of the movable base for driving the horizontal plate to move. The extension mechanism includes a first lead screw rotatably connected to the top of the movable base and vertically arranged, a transmission assembly mounted on the top of the movable base for driving the first lead screw to rotate, a connecting plate threaded to the first lead screw, and a connecting plate mounted on the top of the movable base. The system includes a guide assembly for guiding the connecting plate and a linkage assembly mounted on the top of the movable base for driving the horizontal plate to move vertically. The linkage assembly includes a plurality of first vertical rods vertically fixed to the top of the movable base. Each first vertical rod is slidably connected to a first sliding sleeve along the vertical direction. A first connecting rod is provided between the first sliding sleeve and the connecting plate, and the two ends of the first connecting rod are respectively hinged to the first sliding sleeve and the connecting plate. Each first sliding sleeve is hinged to a second connecting rod, and the top of the plurality of second connecting rods is hinged to a support plate. The top of the movable base is equipped with a guide rod for guiding the support plate, and the support plate is slidably connected to the guide rod along the vertical direction. An extension tube is installed on the support plate, and the top of the extension tube is fixedly connected to the bottom of the horizontal plate.
[0004] However, the above technology has the following technical problems: 1. The hinged first sliding sleeve, first connecting rod, and second connecting rod require more precise machining of the first vertical rod to ensure smooth sliding. However, the space under the first vertical rod is not fully utilized. Due to height constraints, the length of the first vertical rod is directly increased, causing inconvenience for subsequent maintenance and wasting resources during use; 2. The bottom of an elevated bridge is composed of a large flat surface and a curved surface. Cracks are caused by the compression between two sections or environmental stress. Therefore, the flatness test should not be based on the ground but on the bottom surface of the elevated bridge to obtain the most accurate data. Furthermore, some underground roads of elevated bridges are damaged, which greatly affects the practicality of the product. 3. The lifting mechanism of the detection head is supported by the elasticity of a spring, but the spring has a short lifespan and needs to be replaced frequently. While the spring can be used as a buffer, prolonged compression increases its fatigue coefficient, shortens its lifespan, and increases maintenance costs. 4. When used for both downward and fixed movement, the detection head should cover as much detection space as possible. For cracks above, it's difficult for someone below to accurately pinpoint the crack's location. A reasonable detection and movement device is needed for cracks. 5. The height of the detection head needs to be manually adjusted, increasing labor costs and hindering rapid and effective detection, resulting in unnecessary time costs. 6. The fixed position of the detection display cannot be adjusted according to the user's height, increasing the risk of injury during operation. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art, the present invention provides a rapid crack detection system for building engineering.

[0007] Secondly, hook posts are fixedly installed on both concave blocks one and two, and tension springs are installed between the hook posts on concave blocks one and two, with the two ends of the tension springs respectively sleeved on the hook posts on both sides.
[0008] Furthermore, a sliding column is fixedly installed on the lower side of the central support block, and a C-shaped ring block is slidably installed on the other end of the sliding column. A column hole is opened on the C-shaped ring block, and the sliding column slides in the column hole. A base is fixedly installed on the lower side of the C-shaped ring block, and a bottom cylinder is fixedly installed on the base. The telescopic shaft of the bottom cylinder is fixedly installed on the central support block. Side blocks are fixedly installed on all four sides of the central support block. A second partition plate is hinged on the side block. A first partition plate is hinged on the other end of the second partition plate. A sliding sleeve is hinged on the other end of the first partition plate. A vertical rod is slidably installed on the sliding sleeve. A fixed seat is fixedly installed at the lower end of the vertical rod. The fixed seat is fixedly installed on the base. A fixed ring is fixedly installed at the end of the vertical rod away from the fixed seat.
[0009] Furthermore, a small abutment is fixedly provided on the first partition plate, and a large abutment is fixedly provided on the side of the second partition plate where the small abutment is located.
[0010] Furthermore, a power storage box and a pressure box are fixedly installed on the chassis, side strips are fixedly installed on both sides of the chassis, U-shaped buckles are fixedly installed on the inner side of the side strips, a rear rail seat is slidably installed on the U-shaped buckle, a rubber buckle is slidably installed on the rear rail seat, a display seat is fixedly installed on the rubber buckle, and casters are fixedly installed on the lower side of the chassis.
[0011] A stop post is slidably mounted on the top plate. A buffer block is fixedly mounted on the upper end of the stop post. A stop spring is sleeved on the stop post. The stop spring is located between the buffer block and the top plate. The lower end of the stop post penetrates the top plate and a stop ring is fixedly mounted on the lower end of the stop post.
[0012] Furthermore, two vertical plates are symmetrically fixedly arranged on the upper top plate. A square groove is opened on the upper top plate. A light column is symmetrically fixedly arranged between the two vertical plates. A lead screw is rotatably arranged between the two vertical plates.

[0014] In summary, the beneficial effects are:
[0015] The actual usable area of the vertical rod 202 is increased, and the length of the vertical rod 202 is shortened, which reduces the subsequent maintenance cost. The shortened length also reduces the processing cost.
[0016] Using the bottom surface of the viaduct as a plane reference avoids erroneous data due to slant, providing a true and effective survey foundation. Furthermore, it eliminates the need to consider the flatness of the ground beneath the viaduct, increasing the practicality of the device.
[0017] The overall device has a buffer spring and an automatic return spring on the flat part of the detection head, which reduces the stress on the spring, increases the service life of the spring, and reduces maintenance costs.
[0018] With the help of the cylinder, the operator only needs to raise the cylinder. With the action of the upper part that automatically keeps the plane with the overpass, and with the buffering effect of the spring, the device can reach the survey position in the first time, reducing labor costs and achieving speed and efficiency.
[0019] Cracks are usually irregular long cracks. This device can move the detection head to a larger area for surveying at a single point by clicking, reducing the need to move and locate the bottom position due to the need to measure multiple sets of data, and reducing back-and-forth positioning.
[0020] The angle of the display stand can be adjusted according to the user's height to accommodate users within a certain height range and reduce the risk of injury. Attached Figure Description

[0040] Working principle:
[0041] The display stand 104 is secured to the rear rail 107 via the U-shaped buckle 108 on the rear side. The specific angle is determined based on the user's height, making it more ergonomic. Holding the rear rail 107, move the device to the bottom of the location to be surveyed. After determining whether it is within the survey height range of this device, begin surveying the crack. Activate the bottom cylinder 208, which will smoothly move the middle support block 206 upwards along the column hole 2091, roughly to block 21. As the middle support block 206 moves, the small abutment block 212 causes the angle between the first partition plate 204 and the second partition plate 205 to change, causing the large abutment block 211 and the small abutment block to touch together. This makes the first partition plate 204 and the second partition plate 205 move upward as a whole, making full use of the height of the vertical rod 202 without affecting the function. When the stroke of the bottom cylinder 208 is fully released, the buffer block 403 touches the bottom of the viaduct, and the upper support cylinder 306 begins to release air. 6. Moving downwards with connecting plate 305, the upper top plate 408, due to the cooperation of the central column block 407 and the ball column 409, and the force of the bottom cylinder 208, causes the upper buffer block 403 to fully contact the bottom of the viaduct. This achieves alignment with the flatness of the viaduct's bottom. The motor 406 is then started, causing the lead screw slider 508 to move, which in turn moves the fixed horizontal plate 505 to collect more data on a single crack. After use, the bottom... When the air cylinder 208 is depressurized, the middle support block 206 lowers along with the other components. At this time, the upper top plate 408 returns to its upright position under the action of the tension spring 309. However, because the tension spring 309 has an error in its elastic coefficient, air is injected into the support cylinder 306 to make the rubber pad 307 fit tightly against the bottom surface of the upper top plate 408, so that the upper top plate 408 can be stable and not tilted. After the air cylinder 208 at the bottom is completely depressurized, the device is moved to the next survey location by holding the rear rail seat 107.
