Description

Technical Field

[0001] The utility model relates to the technical field of measuring point position arrangement devices, in particular to a measuring area measuring point position arrangement device for a comprehensive concrete crack detector. Background Technique

[0002] In concrete structures and concrete bridges, cracks are relatively common quality problems, which can generally be divided into two categories: structural cracks and non-structural cracks. Structural cracks are mainly caused by insufficient bearing capacity and are also signs of the beginning of structural damage or insufficient strength. Non-structural cracks are mainly caused by non-structural factors such as settlement, temperature, and shrinkage, resulting in the concrete being cracked. However, non-structural cracks have little impact on the bearing capacity of the structure. The appearance of concrete cracks weakens the integrity and bearing capacity of the building and reduces the durability of the concrete structure. Therefore, the detection of cracks is particularly important. Through the detection of aspects such as width, depth, position, and distribution characteristics, analysis, evaluation, and treatment are carried out. Currently, for the detection of crack depth, the ultrasonic single-sided flat measurement method is the most common non-destructive detection method.

[0003] During the detection, with the crack position as the center, two probes are respectively placed on the concrete surfaces on both sides of the crack for measurement.

[0004] For the first type of cross-crack and non-cross-crack probe scale for fixing the concrete crack depth detection probe, in order to improve the detection accuracy, multiple measurements are carried out at different intervals on both sides of the crack. It is necessary to manually draw lines on the concrete surface in advance to determine the measurement points, and then apply a coupling agent at the corresponding positions to facilitate the detection of the ultrasonic probe. However, the coupling agent is easy to cover the marked measurement points, which easily causes dimensional deviation of the probe position and affects the accuracy of crack detection. In addition, for the first type of non-cross-crack measurement of the sound velocity of homogeneous concrete and cross-crack measurement of the sound velocity to determine the crack depth, two scales need to be replaced for measurement, and the process is relatively troublesome and not conducive to use. Therefore, a measuring area measuring point position arrangement device for a comprehensive concrete crack detector is proposed to solve the problems mentioned above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a measuring area measuring point position arrangement device for a comprehensive concrete crack detector, which solves the problems that it is easy to cause dimensional deviation of the probe position, affecting the accuracy of crack detection, and the process is relatively troublesome and not conducive to use.

[0006] To achieve the above object, the utility model provides the following technical solution: A measuring area measuring point position arrangement device for a comprehensive concrete crack detector, including a guide rail fixing base and a frame, and a measuring point arrangement component is arranged outside the guide rail fixing base;

[0007] The measuring point arrangement component includes a movable rod fixedly installed on the side of the guide rail fixed base. An infrared device is fixedly installed in the middle section of the movable rod. A guide rail seal seat is slidably connected to the outer surface of the movable rod.

A spring and a limiting rod are fixedly connected to the inner side of the sleeve. The top end of the spring is fixedly connected to a pressing plate. A piston rod fixedly connected to the middle of the pressing plate penetrates through the sleeve and extends to its bottom end. A probe seal is fixedly connected to the bottom end of the piston rod.

[0008] Furthermore, the number of the guide rail fixed base, the movable rod, and the guide rail seal seat is two each, and the pressing plate is slidably connected to the limiting rod.

[0009] Furthermore, the number of the card slots is several, and the inner edge spacing of the probe seal increases by 50 mm as the increment.

[0010] Furthermore, a lead screw is rotatably connected to the top of the frame. A threaded block is threadedly connected to the outer surface of the lead screw. A knob is fixedly connected to the top end of the lead screw. A moving rod is fixedly connected to the top of the frame. A moving block is slidably connected to the outer surface of the moving rod.

[0011] Furthermore, a connecting rod is fixedly connected to one end of the threaded block and the moving block close to the guide rail fixed base, and the front end of the connecting rod is fixedly connected to the side of the guide rail fixed base.

[0012] Furthermore, moving openings are formed on the left and right sides of the frame, and the connecting rod passes through the moving openings.

[0013] Furthermore, an arrangement opening is formed on the top of the frame, and the inner diameter of the arrangement opening is larger than the outer diameter of the probe seal.

Among them, when in use, the staff only needs to move the guide rail seal support left and right, so that the guide rail seal support slides on the outer surface of the movable rod, and the precise distance can be adjusted, thereby improving the detection efficiency. At the same time, press the piston rod, so that the piston rod continuously compresses the spring through the pressure plate, thereby driving the probe seal to continuously move downward to leave an impression on the concrete component, and then determine the detection position of the probe, which is relatively convenient. Among them, a number of card slots with an increment of 50 mm for the inner edge distance of the probe seal can fix the inner edge distances of the probe seal to be 50 mm, 100 mm, 150 mm, 200 mm, 250 mm, and 300 mm respectively, and can be used for fixing the probe seal at different positions, so as to ensure the symmetrical state of the guide rail seal support and avoid the situation of offset in the arrangement of the measuring point position.

An infrared device 4 is fixedly installed in the middle section of the movable rod 3. A guide rail stamp support 5 is slidably connected to the outer surface of the movable rod 3. A clamping groove 6 is opened on the outer surface of the movable rod 3. A sleeve 7 is fixedly connected to the inner side of the guide rail stamp support 5. A spring 8 and a limiting rod 12 are fixedly connected to the inner side of the sleeve 7. The top end of the spring 8 is fixedly connected to a pressing plate 9. A piston rod 10 is fixedly connected to the middle of the pressing plate 9 and penetrates through the sleeve 7 and extends to its bottom end. The bottom end of the piston rod 10 is fixedly connected to a probe stamp 11. By setting the measuring point arrangement component, when arranging the measuring area for detecting concrete component cracks, there is no need to manually draw the measuring area by hand. When arranging the measuring area across the crack, the infrared device can accurately arrange the measuring area in the direction perpendicular to the normal direction of the crack, and conveniently, quickly and integrally realize the arrangement of the measuring area across the crack and not across the crack, which is more conducive to use.

[0025] Among them, when in use, the staff only needs to move the guide rail stamp support 5 left and right, so that the guide rail stamp support 5 slides on the outer surface of the movable rod 3, and the precise distance can be adjusted, thereby improving the detection efficiency. At the same time, pressing the piston rod 10 makes the piston rod 10 continuously compress the spring 8 through the pressing plate 9, thereby driving the probe stamp 11 to move downward continuously to leave an impression on the concrete component, and then determining the probe detection position, which is relatively convenient.

[0026] Among them, a number of clamping grooves 6 with the inner edge spacing of the probe stamp 11 increasing in increments of 50 mm can fix the inner edge distances of the probe stamp 11 to be 50 mm, 100 mm, 150 mm, 200 mm, 250 mm and 300 mm respectively, and can be used for fixing the probe stamp 11 at different positions, so as to ensure the symmetrical state of the guide rail stamp support 5 and avoid the situation of offset in the arrangement of the measuring point position. In addition, the infrared device 4 can continuously irradiate infrared rays to determine whether the standard axis is perpendicular to the crack cross-section method direction, so as to facilitate the staff to confirm the accuracy of the measuring point position.

[0027] It should be noted that the number of the guide rail fixing base 1, the movable rod 3 and the guide rail stamp support 5 is two. The pressing plate 9 is slidably connected to the limiting rod 12. The number of the clamping grooves 6 is several, and the inner edge spacing of the probe stamp 11 increases in increments of 50 mm.

Connecting rods 18 are fixedly connected to one end of the threaded block 14 and the moving block 16 close to the guide rail fixing base 1.

Through the cooperation of the lead screw 13, the threaded block 14, the knob 17, the moving rod 15, the moving block 16 and the connecting rod 18, during use, the staff only needs to rotate the knob 17 clockwise or counterclockwise, so that the lead screw 13 rotates clockwise or counterclockwise, thereby finally driving the measuring point arrangement component to lift inside the frame 2, and then adjusting the horizontal height of the probe stamp 11 to better adhere to the concrete member for accurate imprinting.

[0032] During use, the staff first rotates the knob 17 clockwise or counterclockwise, so that the lead screw 13 rotates clockwise or counterclockwise, thereby finally driving the measuring point arrangement component to lift inside the frame 2, and then adjusting the horizontal height of the probe stamp 11 to better adhere to the concrete member for accurate imprinting. After the height adjustment is completed, the staff only needs to move the guide rail stamp support 5 left and right, so that the guide rail stamp support 5 slides on the outer surface of the movable rod 3, and the accurate distance can be adjusted, thereby improving the detection efficiency. At the same time, the piston rod 10 is pressed, so that the piston rod 10 continuously compresses the spring 8 through the pressing plate 9, thereby driving the probe stamp 11 to continuously move downward to imprint on the concrete member, and then determining the probe detection position, which is relatively convenient. Among them, a number of card slots 6 with an increment of 50 mm for the inner edge spacing of the probe stamp 11 can fix the inner edge distances of the probe stamp 11 to be 50 mm, 100 mm, 150 mm, 200 mm, 250 mm and 300 mm respectively, and can be used for fixing the probe stamp 11 at different positions, so as to ensure the symmetrical state of the guide rail stamp support 5 to avoid the situation of offset in the arrangement of the measuring point positions.
