Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and in particular to a multi-channel ultrasonic pile measuring instrument for engineering testing. Background Technology

[0002] In various projects involving pile foundations, such as building construction, bridge construction, and rail transit engineering, multi-channel ultrasonic pile measuring instruments are used to detect the integrity of the pile body. They can promptly detect defects such as mud inclusions, broken piles, and diameter reduction inside the pile body, ensuring that the quality of the pile foundation meets the design and specification requirements and guaranteeing the safety and stability of the entire engineering structure.

[0003] A search revealed Chinese Patent Publication No. CN218233584U, which discloses an ultrasonic flaw detector for foundation pile testing in building engineering. The flaw detector includes a main body with a display screen mounted on its front surface. It also includes protective components, which consist of a movable plate, a protective cover, a fixed plate, a placement groove, a rubber pad, a spring, and a receiving groove. The front surface of the protective cover has a placement groove for inserting the flaw detector. The fixed plates are symmetrically fixed to the inner sides of the flaw detector, and each of the two fixed plates has a receiving groove on its opposite side. One end of the movable plate is embedded in the receiving groove, and the other end extends out of the receiving groove and is connected to a rubber pad. The beneficial effect of this invention is that the designed protective components ensure the flaw detector is placed stably. This design further enhances the protection of the flaw detector body, reducing damage caused by accidental slippage. The positioning component allows the positioning pin to be inserted along the positioning groove during use, improving the positioning of the flaw detector body during installation. Currently, pile foundation quality inspection is a crucial aspect of construction engineering. Traditional inspection methods mainly include static load testing, dynamic penetration testing, and core drilling. While these methods can meet inspection needs to some extent, they have many limitations in practical applications. In recent years, with the development of engineering inspection technology, ultrasonic pile measuring instruments have gradually been widely used in pile foundation inspection due to their high efficiency and accuracy. However, static load testing and dynamic penetration testing methods are complex to operate, time-consuming, and subject to significant site limitations. Utility Model Content

[0040] Specifically, cable 4 is connected to instrument 1 and wound around the recording wheel 7. The housing 8 is placed in the ground, and the motor 10 inside the housing 8 is started. Motor 10 drives the output shaft 11 to rotate, which in turn drives the crank 13 below to rotate. Crank 13 drives shaft 14 to rotate, and shaft 14 on detector 15 drives differential gears 16 and 17 to rotate, causing detector 15 to slowly twist and rotate. Shaft 18 on detector 15 rotates within connecting block 19, and shafts 20 on the left and right sides of connecting block 19 are mounted on support arms 12.

The handle 27 is used to move the reel 5. The outer wall of the handle 27 is equipped with an anti-slip sleeve 28. The anti-slip sleeve 28 is used to prevent the hand from easily slipping off the handle 27 when lifting.

[0042] Specifically, when encountering complex geological conditions, an external force impacts the rubber shell 207. The slide rail 203 inside the square groove 201 of the shell 8 slides within the slider 202. The slide rail 203 on the fixed plate 204 presses against the spring 205 on the inner wall of the rubber shell 207. At this time, the spring 205 deforms and rebounds due to inertia, causing the slide rail 203 to spring back. The rubber column 206 inside the square groove 201 presses against the slider 202. At this time, the rubber column 206 buffers and limits the sliding distance of the slide rail 203.

The chassis 29 is used to rotate the turntable 30, which allows the recording wheel 7 to rotate in any direction. The foot pedal 31 can fix the tripod 6 to the ground. The anti-slip mat 32 is used to prevent slipping when stepping on the foot pedal 31.

[0045] Working principle: Cable 4 is connected to instrument 1 and wound around the recording wheel 7. The housing 8 is placed in the ground and the motor 10 inside is started. Motor 10 drives the output shaft 11 to rotate, which in turn drives the crank 13 below to rotate. Crank 13 drives the shaft 14 to rotate, which in turn drives the differential gears 16 and 17 on detector 15 to rotate, causing detector 15 to slowly twist and rotate. The shaft 18 on detector 15 rotates within the connecting block 19, and the shafts 20 on the left and right sides of the connecting block 19 rotate... The support arm 12 rotates, enabling the detector 15 to rotate and scan stably in multiple directions within the connecting block 19. This allows for the rapid acquisition of comprehensive information about the circumference of the pile body. Combined with axial scanning, this enables efficient detection of the entire pile surface, reducing detection time and workload. The main control unit quickly filters, amplifies, and digitizes the raw data received, generating images or curves to be displayed on the screen for operators to view. Simultaneously, the data transmission module synchronously sends the processed results to an external terminal for remote monitoring and data analysis.

[0046] When encountering complex geological conditions, an external force impacts the rubber shell 207. The slide rail 203 inside the outer square groove 201 of the shell 8 slides within the slider 202. The slide rail 203 on the fixed plate 204 presses against the spring 205 on the inner wall of the rubber shell 207. At this time, the spring 205 deforms and rebounds due to inertia, causing the rubber column 206 inside the square groove 201 to press against the slider 202. The rubber column 206 acts as a buffer and limits the sliding distance of the slide rail 203. The spring 205 effectively absorbs and buffers vibration energy, preventing components from being damaged or loosened due to vibration, thus ensuring the stability and reliability of the equipment.
