TECHNICAL FIELD

[0001] The present application relates to the field of construction equipment, in particular to a concrete pouring and vibrating operation area pre-vibration detection device and method. BACKGROUND

[0002] After concrete pouring and before vibrating operation, the steel bar distribution and the concrete pouring surface height of the concrete pouring area need to be detected in order to avoid vibrating the vibrating rod under the steel bar. In the field, the naked eye is used to observe the steel bar distribution and the concrete pouring surface height before vibrating the concrete pouring area by manually holding the vibrating rod or using a mechanical device to carry the vibrating rod. This not only has low detection efficiency, but also has the problem of high-altitude operation hazards. SUMMARY

[0003] The purpose of the present application is to provide a concrete pouring and vibrating operation area pre-vibration detection device and method to solve the problems of low detection efficiency and high-altitude operation hazards in manually detecting the steel bar distribution and the concrete pouring surface height.

[0004] To solve the above technical problems, the technical solution provided by the present application is: a concrete pouring and vibrating operation area pre-vibration detection device, comprising a hole base, a gear ring disc arranged below the hole base, an eccentric motor vertically arranged on the hole base, the eccentric motor being eccentrically connected to the gear ring disc through a transmission mechanism, a binocular vision camera vertically downward arranged on the gear ring disc, and at least one set of laser ranging sensors.

[0005] Further, the concrete pouring and vibrating operation area pre-vibration detection device provided by the present application, the transmission mechanism is a gear transmission, a belt transmission or a chain transmission.

[0006] Further, the concrete pouring and vibrating operation area pre-vibration detection device provided by the present application, each set of the laser ranging sensors comprises a plurality of laser ranging sensors arranged in a straight line.

[0007] Further, the concrete pouring and vibrating operation area pre-vibration detection device provided by the present application, the laser ranging sensors are two sets, and the straight line directions of the two sets of laser ranging sensors are orthogonally distributed.

[0008] Further, the concrete pouring and vibrating operation area pre-vibration detection device provided by the present application, the eccentric motor is a servo motor or a stepping motor.

[0009] A concrete pouring and vibrating operation area pre-vibration detection method using the above-mentioned concrete pouring and vibrating operation area pre-vibration detection device, comprising: Connect the binocular vision camera, each set of laser rangefinders and eccentric motor to the controller, and pass the vibrating rod and its connected cable through the perforated base and gear ring to extend downwards below the binocular vision camera; The controller uses a binocular vision camera to identify the distribution of the vibrating rod and the reinforcing bars in the concrete pouring vibration operation area based on binocular vision technology, and determines whether there is a risk of collision between the sinking path of the vibrating rod and the reinforcing bars below it. The controller detects the elevation of the concrete pouring surface within the coverage width of the corresponding set of laser rangefinders using at least one set of laser rangefinders. When the corresponding set of laser rangefinders falls on the reinforcing bars, the controller controls the eccentric motor to control the gear ring disk to rotate through the transmission mechanism, which in turn drives the binocular vision camera and each set of laser rangefinders to rotate. This changes the detection position of the binocular vision camera and each set of laser rangefinders to perform multiple detections on the distribution of reinforcing bars and the elevation of the concrete pouring surface in the concrete pouring vibration operation area.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a pre-vibration detection device and method for a concrete pouring vibration operation area. It automatically determines whether there is a collision risk between the sinking path of the vibrator and the reinforcing steel below it using a binocular vision camera based on binocular vision technology. The elevation of the concrete pouring surface within the coverage width of at least one set of laser ranging sensors provides data support for adjusting the sinking depth of the vibrator. When the laser ranging sensor detects that the corresponding set of sensors has landed on the reinforcing steel, an eccentric motor controls the rotation of a gear ring disc, synchronously driving the binocular vision camera and each set of laser ranging sensors to rotate. This changes the detection position of the binocular vision camera and each set of laser ranging sensors, allowing for multiple detections of the reinforcing steel distribution and the elevation of the concrete pouring surface in the concrete pouring vibration operation area. This achieves automated obstacle avoidance for the reinforcing steel in detecting the elevation of the concrete pouring surface, thereby improving inspection efficiency. The entire process requires no manual measurement or inspection, avoiding the risks of working at heights.

[0011] The pre-vibration detection device and method for concrete pouring vibration operation area provided by the present invention can provide data support for adjusting the sinking position and sinking depth of the vibrator by detecting the distribution of reinforcing bars and the elevation of the concrete pouring surface, thereby improving the vibration effect.

[0013] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0014] Please refer to Figs. 1-3 This invention provides a pre-vibration detection device 100 for a concrete pouring vibration operation area, including a perforated base 101, a gear ring disk 102 disposed below the perforated base 101, an eccentric motor 103 vertically disposed on the perforated base 101, the eccentric motor 103 being eccentrically connected to the gear ring disk 102 via a transmission mechanism, and a binocular vision camera 104 and at least one set of laser rangefinders 105 vertically disposed on the gear ring disk 102. The holes in the perforated base 101 refer to the center holes. The eccentric motor 103 can be a servo motor or a stepper motor. To achieve rotational control of the gear ring disk 102, the transmission mechanism can be a gear drive, belt drive, or chain drive.

[0015] Please refer to Figs. 1-3 This invention also provides a method for pre-vibration testing in a concrete pouring vibration operation area, using the aforementioned pre-vibration testing device 100 for the concrete pouring vibration operation area, comprising: In step S1, connect the binocular vision camera 104, each set of laser rangefinders 105, and the eccentric motor 103 to the controller 300. Pass the vibrating rod 200 and its connected cable 201 through the perforated base 101 and gear ring 102, extending downwards below the binocular vision camera 104. To achieve coordinated control, the frequency converter of the vibrating rod can be connected to the controller 300, thus making the controller 300 the main controller, and separately controlling the detection and vibration.

[0016] In step S2, the controller 300 uses the binocular vision camera 104 to identify the distribution of the vibrating rod 200 and the reinforcing bars in the concrete pouring vibration operation area based on binocular vision technology, and determines whether there is a risk of collision between the sinking path of the vibrating rod 200 and the reinforcing bars below it.

[0017] In step S3, the controller 300 detects the elevation of the concrete pouring surface within the coverage area of ​​at least one set of laser rangefinders 105. When the corresponding set of laser rangefinders 105 is positioned on the reinforcing steel, the controller 300 controls the eccentric motor 103 to rotate the gear ring disk 102 via the transmission mechanism, synchronously driving the binocular vision camera 104 and each set of laser rangefinders 105 to rotate. This changes the detection position of the binocular vision camera 104 and each set of laser rangefinders 105, allowing for multiple detections of the reinforcing steel distribution and the elevation of the concrete pouring surface in the concrete pouring and vibration operation area.

[0018] The pre-vibration detection device 100 and method for concrete pouring vibration operation area provided in this embodiment of the invention automatically determines whether there is a risk of collision between the sinking path of the vibrator 200 and the reinforcing steel below it through binocular vision camera 104 based on binocular vision technology; the elevation of the concrete pouring surface within the coverage width of the corresponding set of laser rangefinders 105 is detected by at least one set of laser rangefinders 105, providing data support for adjusting the sinking depth of the vibrator 200; when the corresponding set of laser rangefinders 105 is detected to be landing on the reinforcing steel, the gear ring disk 102 is rotated by the eccentric motor 103 to synchronously drive the binocular vision camera 104 and each set of laser rangefinders 105 to rotate, thereby changing the detection position of the binocular vision camera 104 and each set of laser rangefinders 105 to perform multiple detections on the distribution of reinforcing steel and the elevation of the concrete pouring surface in the concrete pouring vibration operation area, realizing automated obstacle avoidance of reinforcing steel to detect the elevation of the concrete pouring surface, thereby improving detection efficiency, eliminating the need for manual measurement and detection throughout the process, and avoiding the risks of high-altitude operations.

[0019] The pre-vibration detection device 100 and method for the concrete pouring vibration operation area provided in this embodiment of the invention can provide data support for adjusting the sinking position and sinking depth of the vibrator 200 by detecting the distribution of reinforcing bars and the elevation of the concrete pouring surface, thereby improving the vibration effect.

[0020] To improve the accuracy of elevation detection when the concrete pouring surface is uneven, the present invention provides a pre-vibration detection device 100 and method for the concrete pouring vibration operation area. Each group of laser rangefinders 105 includes multiple laser rangefinders arranged in a straight line. Each group of laser rangefinders 105 can perform linear scanning detection of the concrete pouring vibration operation area. By rotating each group of laser rangefinders 105, a fan-shaped or circular scanning detection of the concrete pouring vibration operation area can be achieved. This allows for the detection of the overall elevation distribution of the concrete pouring surface within the scanning detection area when the concrete pouring surface is uneven. For example, rotating the gear ring 102 one revolution every 3 seconds controls the rotation speed of each group of laser rangefinders 104, enabling real-time detection of the bottom concrete pouring surface elevation at different positions by each group of laser rangefinders 104, avoiding the problem of laser beam obstruction caused by the arrangement of rebar spacing. The real-time monitoring frequency of each group of laser rangefinders 104 can be one data point every 0.5 seconds. After each group of laser rangefinders 104 rotates 360°, each group of laser rangefinders 104 will collect 6 sets of data, with each set of data containing at least 2 values. At least 12 values ​​are then compared, and the maximum value is taken to represent the elevation of the concrete pouring surface. This avoids the situation where single-point scanning detection cannot truly reflect the elevation of the concrete pouring surface when there are uneven areas.

[0021] To avoid the problem of the laser beam of the laser rangefinder 104 being blocked by the rebar arrangement, the pre-vibration detection device 100 and method for the concrete pouring vibration operation area provided in this embodiment of the invention uses two sets of laser rangefinders 105, which are orthogonally distributed in the straight line direction. When one set of laser rangefinders 105 is blocked by the rebar, detection is performed by the other set of laser rangefinders 105, thereby improving the accuracy of the detection data and avoiding detection of the rebar elevation. Alternatively, the elevation detection of the rebar can be avoided by rotating the gear ring 102 to change the position of each set of laser rangefinders 105, thus improving the accuracy of the concrete pouring surface detection data.
