Problems solved by technology
In fact, once the pipe is blocked on the construction site, workers and technicians cannot quickly and accurately find the location of the blocked pipe, which will affect the construction efficiency and progress, and even delay the construction period, resulting in huge economic losses.

Embodiment Construction
[0026] exist figure 1 and figure 2 Among them, 1 is the base part of the photoelastic display sheet, 2 is the pump tube body, 3 is the welding position, and 4 is the cutout. The photoelastic display sheet is composed of its base part and photoelastic material. Stainless steel material or plastic with good surface reflective performance is selected, and the base part 1 of the photoelastic display sheet is precisely processed according to the diameter of the pump tube, so that the lower surface thereof can be closely attached to the pump tube. Precisely process the shape of the notch according to the design drawing, and cut the required notch through the base part 1 of the photoelastic display sheet up and down. The upper surface is coated with photoelastic materials or bonded with photoelastic patches, and the standard is to coat or paste the complete upper surface. So far, the processing and production of the photoelastic display sheet has been completed. Weld the process...

The invention relates to a tube plugging detection system of a concrete pump. The tube plugging detection system of a concrete pump is used for detecting the tube plugging situation for concrete pumping construction, and includes photoelastic display sheets. The tube plugging detection system of a concrete pump is characterized in that each photoelastic display sheet includes a matrix part 1; a notch 4 is formed in the matrix part 1; the outer surface of the matrix part 1 is coated with a photoelastic material layer; the inner surface tube plugging detection system of a concrete pump fits the outer surface of a conveying pipeline to be detected; the plurality of photoelastic display sheets are respectively fixed at different parts of the conveying pipeline; the tube plugging detection system also includes a light source, a polarizing film 5 and a polarization analyzer 6; and the light emitted from the light source irradiates to one photoelastic display sheet after passing through the polarizing film 5, and then the light reflected from the photoelastic display sheets can be emitted out from the polarization analyzer 6.
Description
technical field [0001] The invention belongs to the technical field of civil engineering and relates to a concrete pump pipe plugging detection system. Background technique [0002] Due to many environmental factors and human factors, concrete pipe plugging occurs from time to time. The methods for judging whether the pipe is blocked are as follows: when the concrete is pumped, the pipe is usually blocked. From the perspective of the pumping oil pressure, if the peak value of the pressure of each pumping stroke rises rapidly with the alternation of strokes, and quickly reaches the set value pressure, the normal pumping cycle stops automatically, and the main oil circuit overflow valve makes an overflow sound, indicating that the pipe has been blocked. On the other hand, the condition of the pipeline can be observed. During normal pumping, the pipeline and the pump only vibrate slightly. If there is a sudden violent vibration, although the pumping operation is still in progr...
