[0002] Railway piling provides the cornerstone for the stability of railway tracks. After the railway pile driver drives the stainless steel drill rod into the ground, it pours in mortar concrete. The poured mortar concrete needs to reach a preset height to provide good stability.
[0003] Existing methods make it difficult to accurately detect whether mortar concrete has reached a preset height. Utility Model Content
[0004] In view of the above problems, the present application provides an ultrasonic mortar detection sensor and a mortar detection device to solve the technical problem that the existing method is difficult to accurately detect whether the mortar concrete has reached a preset height.
[0005] To achieve the above objectives, in a first aspect, the inventors provide an ultrasonic mortar detection sensor, comprising:
[0006] Drill pipe, which is hollow inside;
[0007] Transmitting transducer, which is installed on one side outside the drill pipe;
[0008] A receiving transducer is installed on the other side of the drill pipe corresponding to the transmitting transducer;
[0009] The single chip microcomputer is connected to the transmitting transducer and the receiving transducer respectively. The single chip microcomputer is used to transmit a pulse signal to the transmitting transducer and to output an alarm after receiving an echo signal from the receiving transducer.
[0010] Different from the existing technology, the technical solution of the present application utilizes the extremely strong reverberation signal generated during the transmission of ultrasonic waves in the drill rod. The interfering reverberation signal is reversely utilized, the transducer is used to detect the signal, and the single-chip microcomputer is used to analyze the received signal. Specifically, when the transducer detects that there is no sand and gravel concrete at the corresponding position of the drill rod, the reverberation signal is very large, and the single-chip microcomputer determines that there is no sand and gravel concrete in the drill rod; and when the drill rod is filled with sand and gravel concrete, there are a large number of bubbles in the sand and gravel concrete, which instantly absorb all the reverberation signals. At this time, it is determined that the drill rod corresponding to the transducer is full of sand and gravel concrete, and an alarm signal is given through the single-chip microcomputer to remind the staff, so as to accurately judge that the mortar concrete has reached the preset height.
[0011] As an embodiment of the present invention, the ultrasonic mortar detection sensor further includes two cables, the transmitting transducer is connected to the single-chip microcomputer via one cable, and the receiving transducer is connected to the single-chip microcomputer via another cable.
[0012] In this way, by setting up a cable to connect the transmitting transducer and the receiving transducer to the microcontroller, the transducer detection signal can be transmitted to the microcontroller, and the microcontroller then sends an alarm signal based on the detection signal to prompt the staff.
[0013] As an embodiment of the present invention, the ultrasonic mortar detection sensor further includes an outer tube, which is sleeved outside the drill rod, with a gap between the outer tube and the drill rod, and the transmitting transducer and the receiving transducer are located in the gap.
[0014] In this way, the transmitting transducer and the receiving transducer can be protected by providing the outer tube.
[0015] As an implementation mode of the present invention, the drill rod is welded to the outer tube.
[0016] In this way, by welding the drill rod to the outer tube, the outer tube and the drill rod can be better connected.
[0017] As an implementation manner of the present invention, the transmitting transducer and the receiving transducer are mounted on the inner wall of the outer tube via fasteners.
[0018] In this way, the transmitting transducer and the receiving transducer can also be detachably mounted on the outer tube, which facilitates installation and subsequent maintenance or disassembly.
[0019] As an embodiment of the present invention, the diameter of the outer tube is 235 mm, the diameter of the drill rod is 170 mm, and the gap is 32.5 mm.
[0020] Thus, it is preferred to set the diameter of the outer tube to 235 mm, the diameter of the drill rod to 170 mm, and the gap to 32.5 mm, which is more conducive to the installation and detection of the transducer.
[0021] As an embodiment of the present invention, there are more than two transmitting transducers and receiving transducers, one transmitting transducer corresponds to one receiving transducer, and more than two transmitting transducers are installed at intervals along the vertical direction on one side of the drill rod, and more than two receiving transducers are installed at intervals along the vertical direction on the other side of the drill rod.
[0022] In this way, a plurality of transmitting transducers and receiving transducers can be provided at different positions of the drill pipe along the vertical direction, so as to determine the position requiring an alarm according to actual usage.
[0023] As an embodiment of the present invention, the height of the drill rod in the vertical direction is 10000 mm, wherein a transmitting transducer and a receiving transducer are installed on both sides of the drill rod at a height of 6000 mm from top to bottom in the vertical direction, and another transmitting transducer and a receiving transducer are installed on both sides of the drill rod at a height of 8000 mm from top to bottom in the vertical direction.
[0024] Thus, two transmitting transducers and receiving transducers are optionally provided and respectively installed on both sides of the drill pipe at a height of 6000 mm and 8000 mm from top to bottom in the vertical direction.
[0025] To achieve the above objectives, in a second aspect, the inventors provide a mortar detection device, comprising:
[0026] As any one of the ultrasonic mortar detection sensors provided by the inventors above;
[0027] The host computer and the microcontroller are connected via RS485 communication.
[0028] Different from the existing technology, the technical solution of this application receives the information output by the microcontroller through the host computer, especially the alarm signal output by the microcontroller. The staff can receive the alarm information in time through the host computer and stop pouring, so that the mortar concrete can be accurately poured to the preset height.
