Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a large-volume concrete crack monitoring device. Background Art

[0002] A mass concrete crack monitoring device is a device used to detect and record cracks that appear in mass concrete structures. It usually includes sensors, monitoring instruments and data recording systems, which can measure the width, depth and changes of cracks in real time. This device helps to assess the health of concrete structures, prevent potential structural problems, and ensure the safety and durability of buildings or infrastructure;

[0003] After searching, a Chinese patent with the announcement number of CN215574854U discloses a large-volume concrete temperature gradient crack monitoring device. The patent records that by placing the protective structure in the center of the large-volume concrete to be poured, and then applying anti-sticking glue on the side wall surface of the protective structure, and then pouring concrete with the protective structure as the center, the protective structure is taken out after the large-area concrete solidifies in the later stage, the temperature sensing structure and the acoustic emission detection structure are installed inside the protective structure, so that the temperature sensing structure and the acoustic emission detection structure monitor the poured large-area concrete, and after the large-area concrete is completely solidified, the temperature sensing structure and the acoustic emission detection structure are taken out. When the acoustic emission detection structure is taken out, the driving structure is first compressed into the recovery structure, so that the driving structure compresses the limiting structure, so that the opening of one end of the protective cover of the limited temperature sensing structure and the acoustic emission detection structure is opened, and then the driving structure is rotated to drive the recovery structure to rotate inside the protection structure, so that the recovery structure pulls the temperature sensing structure and the acoustic emission detection structure into the protection structure, and then the protection structure is pulled out from the inside of the large area concrete, and then the recovery structure is pulled out from the inside of the protection structure. This device has a technical solution with the advantage of being convenient for taking out the detection device after detecting the concrete temperature and cracks;

[0004] In this solution, when detecting large-area concrete cracks, the staff uses the device for detection. The staff has limited height, so they can only detect the positions that can be touched. When the concrete cracks are located higher or farther away, they need to use external tools (ladders) to climb and then detect. When carrying external tools, it is time-consuming and unsafe, which greatly reduces work efficiency. In order to solve this technical problem, the utility model proposes a large-volume concrete crack monitoring device. Utility Model Content

[0005] (1) Technical problem to be solved

[0006] In this solution, when detecting large - area concrete cracks, the staff use this device for detection. Since the height of the staff is limited, they can only detect the positions that can be touched. When the concrete crack position is relatively high or far away, external tools (ladders) need to be used for climbing and then detection. When carrying external tools, it takes time and is also not safe, resulting in a significant reduction in work efficiency. To solve this technical problem, the present utility model proposes a large - volume concrete crack monitoring device.

[0015] (III) Beneficial Effects

[0016] The present utility model provides a large-volume concrete crack monitoring device, which has the following beneficial effects:

[0017] (1) The connection frame is convenient for the operator to lift and adjust through the handle. The motor is installed inside the connection frame and drives the threaded rod to rotate. The rotation of the threaded rod drives the first connecting block to move along its axial direction. The first connecting block and the fixed block cooperate through a linkage relationship. The fixed block slides in the chute to ensure that its moving direction is consistent. The movement of the fixed block further pushes the connecting rod. The connecting rod is connected to the universal joint and is connected to the detection head through the screw on the universal joint. Through the nut and the connecting head, the detection head can be stably fixed on the universal joint. The entire system realizes the front and rear adjustment of the detection head through this precise cooperation, allowing the operator to perform accurate detection at different positions. Such a design not only improves the flexibility and reliability of the system, but also significantly improves the detection efficiency and data accuracy, effectively solving the problem of difficult adjustment of the position of the detection head.

[0018] (2) The protective cover is fixed on the detection device body through the clamping block. The protective cover can stably protect the device body from external damage under the limitation of the clamping block. The push block cooperates with the protective cover, allowing the operator to easily move the protective cover through the push block, so as to conveniently access the device body when needed. The visual window is arranged above the protective cover, and the operator can observe the data on the device body in real time through it. This design ensures that data monitoring can be carried out without disassembling the protective cover, while protecting the device from physical damage. The push handle is used to push the entire detection device body, and the cooperation with the limit frame can accurately position the device. The overall cooperation effectively solves the problems of device protection and operation convenience. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] Embodiment 1: A large-volume concrete crack monitoring device, including a detection equipment body 1, adjusting mechanisms 2 are arranged on both sides of the detection equipment body 1. The adjusting mechanism 2 includes a connection frame 201. One end of the connection frame 201 is fixedly connected with a handle 202. A motor 203 is fixedly connected inside the connection frame 201. At the same time, the output end of the motor 203 is fixedly connected with a threaded rod 204. A first connection block 205 is threadedly connected to the outer side wall of the threaded rod 204. Fixed blocks 206 are fixedly connected to both side walls of the first connection block 205. Connecting rods 207 are fixedly connected to the outer side walls of the fixed blocks 206. The other ends of the two connecting rods 207 are fixedly connected with a second connection block 208. A universal joint 209 is fixedly connected to the other side of the second connection block 208. A connection head 212 is arranged at the other end of the universal joint 209. At the same time, a detection head 213 is fixedly connected to the bottom of the connection head 212. At the same time, the detection head 213 is connected to the detection equipment body 1 through a connecting wire 3. At the same time, a protection component is arranged outside the detection equipment body 1. The protection component includes a protective cover 6. The threaded rod 204 is rotatably connected inside the connection frame 201. Chutes 214 are opened on both sides of the connection frame 201. At the same time, the fixed blocks 206 correspond to the chutes 214, and the fixed blocks 206 are slidably connected inside the chutes 214. A screw 210 is fixedly connected to the other end of the universal joint 209. A nut 211 is fixedly connected to one side of the connection head 212. And the nut 211 corresponds to the screw 210. At the same time, the screw 210 is threadedly connected inside the nut 211.

[0027] After installing the detection head 213 onto the connection frame 201, it is quickly fixed onto the screw rod 210 of the universal joint 209 through the nut 211 on the connector 212. The staff member holds the handle 202, lifts the connection frame 201, and starts the motor 203 inside the frame. The motor 203 drives the threaded rod 204 to rotate. The rotation of the threaded rod 204 causes the first connecting block 205 to move along its axis. The movement of the first connecting block 205 drives the fixed blocks 206 on both sides to move together. The movement of the fixed blocks 206 further pushes the connecting rod 207 and the universal joint 209 to move backward. The fixed blocks 206 slide within the sliding grooves 214, thereby ensuring that the connecting rod 207 maintains a stable direction during movement. This process enables the detection head 213 to be precisely adjusted back and forth, thus achieving a rapid adjustment of the detection head, facilitating the detection of distant positions, avoiding the problem of inaccurate data, and significantly improving the work efficiency and data accuracy.

[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that on both sides of the detection device body 1, there are fixedly connected clamping blocks 4. The other ends of the clamping blocks 4 are fixedly connected with support plates 5. And the connection frame 201 is arranged on the tops of the clamping blocks 4 and the support plates 5. On the top of the detection device body 1, there is a fixedly connected limit frame 10. Inside the limit frame 10, there is a limit groove 11 opened. At the same time, the protective cover 6 is slidably connected within the limit groove 11. And on the top of the protective cover 6, there is a visual window 8 fixedly connected. On the top of the protective cover 6, there is a push block 7 arranged. Outside the detection device body 1, there is a push handle 9 arranged. At the bottom of the detection device body 1, there are fixedly connected two pairs of brake wheels 12.

[0029] The detection head 213 transmits data to the detection device body 1 through the communication line 3. When the visual window 8 is pushed, it drives the protective cover 6 to move inward and positions it within the limit groove 11, ensuring the stable position of the protective cover 6. At the same time, through the push block 7, the operator can observe the data on the detection device body 1. The protective cover 6 effectively protects the detection device body 1 from damage. In addition, the detection device body 1 can be moved through the cooperation of the push handle 9 and the brake wheels 12, making the movement of the device very convenient.

[0030] Working principle: When the staff needs to detect concrete cracks, first install the detection head 213 on the connection frame 201. At this time, the detection head 213 is quickly screwed onto the screw rod 210 of the universal joint 209 through the nut 211 on the connector 212. Then the staff holds the handle 202 and picks up the connection frame 201. By starting the motor 203 inside the connection frame 201, the motor 203 drives the threaded rod 204 to rotate. When the threaded rod 204 rotates, it drives the first connecting block 205 to move back and forth. When the first connecting block 205 moves, it drives the fixed blocks 206 on both sides. When the fixed blocks 206 move, they drive the connecting rod 207 and the universal joint 209 to move backward. The fixed blocks 206 are limited in the sliding groove 214, so as to ensure that the connecting rod 207 moves in the same direction, thus driving the detection head 213 to move back and forth, realizing the rapid adjustment of the detection head 213, facilitating the detection of farther positions, avoiding inaccurate data, greatly improving the work efficiency and data accuracy. The detection head 213 transmits data to the detection device body 1 through the communication line 3. At this time, pushing the visual window 8 will drive the protective cover 6 to move inward. The protective cover 6 is limited in the limit groove 11, thus positioning the protective cover 6. At the same time, the data on the detection device body 1 can be observed through the push block 7. The protective cover 6 can effectively protect the detection device body 1 from damage. The detection device body 1 can be moved by pushing the push handle 9 in cooperation with the brake wheel 12, which is very convenient.
