Embodiment Construction
[0029] In order to enable those skilled in the art to understand the present invention more clearly, a more detailed description will be given below through embodiments.
[0030] figure 1 with figure 2 The mounting base for the induction device for the concrete conveying pipe in some embodiments of the present invention is shown. Such as figure 1 with figure 2 As shown, the induction device mounting seat for a concrete conveying pipe includes a first pipe body 1 for mounting the induction device, a second pipe body 3 arranged on the outside of the first pipe body 1 and coaxial with the first pipe body 1 , And an isolation device arranged between the second tube body 3 and the first tube body 1. The first tube body 1 and the second tube body 3 form a double-layer tube structure, and the isolation device makes the second tube body 3 receive The effect of the bending torsion force on the first tube body 1 is negligible, and the effect of vibration on the first tube body 1 can be...

The invention provides an induction device mounting base for a concrete conveyer pipe, which comprises a first pipe body used for mounting an induction device, a second pipe body, which is arranged at the outer side of the first pipe body and is coaxial with the first pipe body, and an isolation device arranged between the second pipe body and the first pipe body, wherein a thread guide hole is arranged on the pipe wall of the second pipe body. The invention also provides a pressure measuring apparatus and a friction force measuring apparatus. The pressure measuring apparatus and the friction force measuring apparatus comprise an pressure induction device and an induction device mounting base; the pressure induction device is arranged on the first pipe body of the induction device mounting base, and a signal wire is led out of the second pipe body from the thread guide hole. The invention also provides a concrete pump car, and the induction device mounting base is arranged between a first concrete conveyer pipe and a second concrete conveyer pipe. The induction device mounting base, provided by the invention, effectively avoids the effect of vibration and bending torsion of the conveyer pipe on the induction and can ensure the measuring accuracy.
Description
Technical field [0001] The invention relates to a concrete pump truck, in particular to an induction device mounting seat for a concrete conveying pipe, a pressure measuring device and a friction force measuring device for a concrete conveying pipe, and a concrete pump truck equipped with the sensing device mounting seat. Background technique [0002] In the existing projects, the concrete pumping height is getting higher and higher, and the concrete pump truck is prone to a series of concrete pump truck operation problems caused by insufficient pumping pressure in the process of conveying concrete. The flow of concrete in the conveying pipe is affected by resistance such as pipe friction, and the pressure value of each pipe wall from the feed end to the discharge end gradually decreases. In order to ensure that the concrete can be pumped to a certain height, it is necessary to measure the pressure loss of the fluid along the pipeline. Therefore, it is very necessary to accurate...
