Description

Technical Field

[0001] The present application relates to the field of pile measuring instruments, and in particular to a multi-channel ultrasonic pile measuring instrument with a protective structure. Background Art

[0002] The multi-channel ultrasonic pile tester is a portable, special instrument that uses the ultrasonic transmission method to detect the integrity of concrete piles. A protective shell is set on the outside of the instrument to protect it and effectively prevent it from collision. The instrument uses a multi-channel self-transmitting and self-receiving circuit and can detect multiple sections at the same time. Three or four transducers are placed in the acoustic testing tube, and a full combination test of three or six sections can be completed in one lift, which greatly improves the detection efficiency and reduces the workload of on-site detection personnel. During the test, the test results can be viewed at any time, and the distribution of abnormal points in each section can be displayed graphically. At the same time, the wave train diagram, curve diagram, data list, image diagram, etc. of each section can be displayed. During the test, multiple transducer wires are placed on the depth recording wheel. When the operator adjusts the position of the transducer in the pile at the same time, the operator is required to pull multiple transducer wires at the same time. The multiple transducer wires are set separately. When pulling them at the same time, the multiple transducer wires need to be straightened, which is inconvenient to pull at the same time and is prone to misalignment, resulting in deviations in the adjustment positions of multiple different transducers, which brings inconvenience to the operation and needs to be improved.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0019] The depth recording wheel 3 includes a mounting frame 31 arranged on the upper surface of the fixed block 1 and a lower roller 32 rotatably connected to the inner wall of the mounting frame 31, an upper roller 33 is arranged on the top surface of the lower roller 32, and both ends of the upper roller 33 are rotatably connected to the inner wall of the mounting frame 31, and the surfaces of the lower roller 32 and the upper roller 33 are both provided with wire grooves, the number of which is equal to that of the transducer body 6, and the size of the wire grooves is adapted to the size of the transducer wire 5, and the transducer wire 5 passes through the wire grooves and is connected to the pile measuring instrument body 7;

[0020] The inner wall of the semicircular hole 43 is fixedly connected with a non-slip rubber pad 47. The multiple transducer wires 5 are flattened and placed in the corresponding semicircular holes 43, and then the lower clamping plate 41 and the upper clamping plate 42 are closed. At this time, the outer wall of the transducer wire 5 squeezes the non-slip rubber pad 47 to deform it, so that the multiple transducer wires 5 are flatly clamped to prevent misalignment, which makes it convenient for the operator to pull the multiple transducer wires 5 at the same time to adjust the position of the transducer body 6 in the foundation pile, providing convenience for the adjustment and detection of the multiple transducer bodies 6 inside different foundation piles.

[0021] Reference Figure 1-3 One end of the lower clamping plate 41 is hingedly connected to one end of the upper clamping plate 42, and one side of the lower clamping plate 41 and one side of the upper clamping plate 42 are both provided with a locking buckle 44, which is composed of an inclined circular rod and a round ball. One end of the circular rod is connected to the locking buckle 44, and the other end is welded to the round ball. The inclination directions of the circular rods in the two locking buckles 44 are designed to be relatively opposite, so that the two round balls can contact each other. When the lower clamping plate 41 is engaged with the upper clamping plate 42, the two round balls are staggered to limit each other, thereby achieving the fixation of the lower clamping plate 41 and the upper clamping plate 42;

[0022] The lower surface of the lower clamping plate 41 is fixedly connected with a connecting block 45, and the upper surface of the mounting frame 31 is provided with an installation slot 46.

At this time, the outer wall of the transducer wire 5 squeezes the anti-slip rubber pad 47 to deform it, so that the multiple transducer wires 5 are flatly clamped. The handheld wire clamp element 4 can pull the multiple transducer wires 5 at the same time, so as to synchronously adjust the positions of the multiple transducer bodies 6 in the foundation pile, and the wire clamp element 4 can be fixed on the depth recording wheel 3 by sliding the connecting block 45 into the installation slot 46, so as to prevent the wire clamp element 4 from falling off when not in use.

The multiple transducer wires 5 are flattened and put into the corresponding semicircular holes 43, and then the lower clamping plate 41 and the upper clamping plate 42 are closed. At this time, the outer wall of the transducer wire 5 squeezes the anti-slip rubber pad 47 to deform it, so that the multiple transducer wires 5 are flatly clamped. The handheld wire clamp element 4 can pull and pull the multiple transducer wires 5 at the same time, thereby synchronously adjusting the positions of the multiple transducer bodies 6 in the pile foundation, and using the transducer bodies 6 to detect the pile foundation.
