Description

Technical Field

[0001] The utility model belongs to the field of pile foundation detection, in particular to a pile foundation ultrasonic testing device fixing structure. Background Art

[0002] Ultrasonic testing is one of the most commonly used methods for testing the quality of concrete pile foundations. Two, three or four parallel ultrasonic testing tubes are pre-buried in the pile foundation. A probe is placed in each ultrasonic testing tube. The probe is first placed at the bottom of the ultrasonic testing tube, and the ultrasonic testing tube is filled with water as a coupling medium. The probe is pulled by a counting pulley, and the probe, including the transmitting probe and the receiving probe, moves upward synchronously in the ultrasonic testing tube to detect defects in the pile foundation.

[0003] CN110629809B discloses an ultrasonic detector, which is used to detect the strength of pile foundation, including at least two probe connecting wires, at least two acoustic detection tubes are arranged in the pile foundation, each acoustic detection tube is provided with a probe connecting wire, and a bracket is fixedly arranged at the upper end of each acoustic detection tube, and a support wheel and a clamping wheel are rotatably connected to the bracket, and the clamping wheel and the support wheel clamp the probe connecting wire relative to each other; the support wheel is connected to a transmission device, and the transmission devices on all the acoustic detection tubes rotate synchronously. The invention has the effect of pulling the probe upward at a relatively stable speed.

[0004] There are still some problems in the use of the above patent, such as: when the probe is moved up and down, it is done through a connecting wire. After long-term use, it is easy to cause the connection between the connecting wire and the probe to loosen, thereby affecting the normal use of the probe. At the same time, when the probe moves, there is a lack of a fixing device, which makes it easy for the probe to collide with the inner wall of the acoustic detection tube, thereby causing damage to the internal components of the probe and reducing the service life of the probe. Therefore, we need to propose a fixing structure for a pile foundation ultrasonic testing device. Utility Model Content
