Problems solved by technology
The efficiency of manual measurement is too low, and the measurement process is greatly affected by human factors
Although single-point laser ranging has the characteristics of high precision and non-contact, it can only measure the thickness of a single point, which is time-consuming and laborious.
[0004] There is also a new method to measure by visual means, but this method requires two high-precision cameras, which is expensive and complicated to correct

Embodiment Construction
[0017] like figure 1 and figure 2 As shown in the figure, the device of this embodiment is used in a concrete placing machine. The concrete placing machine walks on the truss above the mold 7 to carry out the placing operation. The device includes a laser ranging sensor (model SK-Z- 20), angle detection device and frame (not shown in the figure). The frame is fixedly mounted on the concrete placing machine, moves with the concrete placing machine, and if the conditions are feasible, the concrete placing machine itself can be equivalent to the frame. The laser ranging sensor is rotatably connected to the frame through a stepping motor, and the rotation axis of the laser ranging sensor is in the same direction as the longitudinal direction of the mold 7 (that is, in the same direction as the forward or backward direction of the concrete placing machine). ), the orientation of the laser ranging sensor is perpendicular to the rotation axis, and the angle detection device is use...

The invention provides a concrete distribution machine material thickness detection device and its measuring method, the thickness detection device includes a laser ranging sensor, an angle detection device, a processor and a frame fixedly installed on the concrete distribution machine, the The laser ranging sensor is rotationally connected to the frame through a stepping motor, the rotation axis of the laser ranging sensor is in the same direction as the length direction of the mould, and the direction of the laser ranging sensor is perpendicular to the rotation axis, The angle detection device is used to detect the rotation angle of the laser distance measuring sensor. There are at least two laser distance measuring sensors, which are respectively located at the front and rear ends of the concrete distribution machine's distribution port, and are respectively used to obtain the front and rear ends of the distribution machine. The data model of the mold bottom plate and the data model of the cloth after the cloth are compared to obtain the thickness of the concrete after the cloth. The invention also provides a detection method using the device.
Description
technical field [0001] The invention belongs to the technical field of thickness measurement, and in particular relates to a device for detecting the thickness of a concrete placing machine and a measuring method thereof in the production of prefabricated building concrete components. Background technique [0002] Since the 21st century, prefabricated assembly technology has developed rapidly. Prefabricated concrete components are the main components of prefabricated buildings, and their quality directly affects the quality of prefabricated buildings. [0003] At present, manual measurement, single-point laser ranging, etc. are generally used for fabric thickness measurement of prefabricated concrete components. The efficiency of manual measurement is too low, and the measurement process is greatly affected by human factors. Although single-point laser ranging has the characteristics of high precision and non-contact, it can only measure the thickness of a single point, wh...
