Description

Technical Field

[0001] The utility model relates to a building detection equipment technology, in particular to a building crack detection device. Background Art

[0002] At present, the total number of engineering safety accidents remains high. Cracks in concrete are a major hazard to the structure. On the one hand, the development of cracks leads to a decrease in structural stiffness and an increase in brittleness, which reduces the performance of the structure. On the other hand, it may accelerate the aging effect of the environment on the structure, causing the surface protective layer to peel off, affecting the durability of the structure. At present, the detection of concrete structure cracks in the engineering field mainly uses concrete crack detection devices, which can identify, extract and calculate the width of cracks and accurately obtain the location of cracks.

[0003] In the prior art, in order to ensure the accuracy of crack depth detection, two detection probes need to be manually pressed on both sides of the crack, and then the distance between the transmitting detection probe and the receiving detection probe and the inside of the crack is measured, and then the depth of the crack to be detected is obtained by the Pythagorean theorem. However, when the two existing detection probes are in use, the distance between the detection probes and the crack on the wall needs to be manually measured, and the distance between the two detection probes must be the same, so that the crack depth obtained is accurate enough. However, during the frequent adjustment process, it is difficult to make the distance of the detection probes completely consistent, which affects the accuracy of crack depth detection. At the same time, some equipment that performs transmission measurement through machinery still requires manual transmission operation, which is more laborious.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] According to an embodiment of the utility model, a building crack detection device is provided.

[0026] The transmitter 3 and the receiver 4 are respectively installed on the connecting structure 2, and the positioning structure 5 positions the detection device on the crack. The transmission structure 1 transmits the connecting structure 2 to make the transmitter 3 and the receiver 4 move at the same distance in relative directions, so that the transmitter 3 and the receiver 4 move to the two ends of the crack, so that the detection and positioning of the building cracks can achieve equidistant detection to prevent errors. The transmitter 3 is a sound wave transmitting device, and the receiver 4 is a sound wave receiving device.

[0027] The transmission structure 1 includes a mounting shell 101, a control panel 102, a mounting cavity 103, a direct drive motor 104, a transmission gear 105, a side panel 106, and a transmission port 107. The control panel 102 is embedded in the mounting shell 101, and a mounting cavity 103 is provided inside the mounting shell 101. The direct drive motor 104 is fixedly installed in the mounting cavity 103, and the driving end of the direct drive motor 104 is connected to the transmission gear 105. Side panels 106 are fixedly connected to both sides of the mounting cavity 103, and a transmission port 107 is opened on the side panels 106.

[0028] The direct-drive motor 104 transmits the power to the rack 201 via the direct-drive transmission gear 105. Due to the servo characteristics of the direct-drive motor 104, the number of transmission circles can be recorded in real time. The transmission distance can be calculated through the radius of the gear using a built-in algorithm, so that the transmission distance of the rack 201 can be displayed in real time without manual measurement. At the same time, the measurement data of the transmitter 3 and the receiver 4 can also be transmitted to the control module built into the control panel 102 through the wireless transmission module. Then, the distance from the deepest part of the crack to the receiver 4 can be used to calculate the crack depth through the built-in Pythagorean theorem algorithm, thereby realizing automation of measurement and calculation, reducing manual intervention, and improving efficiency.

[0029] The connecting structure 2 includes a rack 201, a fixing ring 202, a fixing bolt 203, and a limit block 204. One end of the rack 201 is fixedly connected to the fixing ring 202, and the fixing bolt 203 is passed through the fixing ring 202. The other side of the rack 201 is fixedly connected to the fixing ring 202. The transmission port 107 on the side plate 106 is slidably connected to the rack 201, and the rack 201 is in transmission meshing engagement with the transmission gear 105.

[0030] The rack 201 is relatively transmitted, and the fixed ring 202 is used to fix the transmitter 3 and the receiver 4 by adjusting the fixing bolts 203. Since four sets of fixing bolts 203 are provided, the fixing bolts 203 can be adjusted to make the transmitter 3 and the receiver 4 as close to the midpoint of the fixing ring 202 as possible, thereby improving the accuracy of detection.

[0031] The positioning structure 5 includes a mounting ring 501, a transmission groove 502, a sliding cavity 503, a buffer ring 504, a first mounting groove 505, a positioning cone 506, a second mounting groove 507, a second spring 508, and a first spring 509. A transmission groove 502 is provided in the middle of the mounting ring 501, a sliding cavity 503 is provided at one end of the mounting ring 501, a buffer ring 504 is slidably connected in the sliding cavity 503, a first mounting groove 505 is provided on the buffer ring 504, a positioning cone 506 is slidably connected inside the buffer ring 504, a second mounting groove 507 is provided on the positioning cone 506, a first spring 509 is provided in the first mounting groove 505, and a second spring 508 is provided in the second mounting groove 507.

[0032] During the pressing process of the overall detection device, the positioning structure 5 can first realize the displacement and pressing fixation of the first section through the positioning cone 506, and then continue to apply force to press and fix the buffer ring 504 and the first spring 509 in the second section. Then, the positioning cone 506 can be pressed further to resist the elastic force of the second spring 508 so that the end of the positioning cone 506 contacts the bottom of the transmission groove 502, so that the positioning structure 5 can be adjusted and fixed in multiple sections according to the crack width, thereby improving the fixing effect.

[0033] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0034] In actual application, the transmitter 3 and the receiver 4 are respectively installed on the connecting structure 2, and the positioning structure 5 positions the detection device on the crack. The transmission structure 1 transmits the connecting structure 2 to make the transmitter 3 and the receiver 4 move at the same distance in relative directions, so that the transmitter 3 and the receiver 4 move to the two ends of the crack, so that the detection and positioning of the building cracks can be equidistantly detected to prevent errors. The direct drive motor 104 transmits the rack 201 through the direct drive transmission gear 105. Due to the servo characteristics of the direct drive motor 104, the number of transmission circles can be recorded in real time. The transmission distance can be calculated through the radius of the gear through the built-in algorithm, so that the transmission distance of the rack 201 can be displayed in real time without manual measurement. At the same time, the measurement data of the transmitter 3 and the receiver 4 can also be transmitted to the control module built into the control panel 102 through the wireless transmission module, and then the distance from the deepest part of the crack to the receiver 4 can be obtained through the internal The Pythagorean theorem algorithm is used to calculate the crack depth, realize the automation of measurement and calculation, reduce manual intervention, and improve efficiency. The rack 201 is relatively transmitted, and the fixed ring 202 fixes the transmitter 3 and the receiver 4 by adjusting the fixing bolts 203. Since four sets of fixing bolts 203 are set, the transmitter 3 and the receiver 4 can be placed as close to the midpoint of the fixing ring 202 as possible by adjusting the fixing bolts 203, thereby improving the accuracy of detection. The positioning structure 5 can first realize the displacement pressing and fixing of the first section through the positioning cone 506 during the pressing of the overall detection device, and then continue to apply force to press and fix the buffer ring 504 and the first spring 509 in the second section, and then continue to press to make the positioning cone 506 resist the elastic force of the second spring 508 so that the end of the positioning cone 506 contacts the bottom of the transmission groove 502, so that the positioning structure 5 can be adjusted and fixed in multiple sections according to the crack width, thereby improving the fixing effect.
