Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a non-destructive testing device for pile foundation integrity. Background Technology

[0002] As the "underground foundation" of buildings, bridges, wind power, and other engineering projects, pile foundations are susceptible to defects such as cracks, necking, and segregation, which directly affect their bearing capacity. Non-destructive testing devices for pile foundation integrity can accurately identify these hidden defects without damaging the pile foundation, preventing safety accidents such as building settlement and bridge collapse caused by pile foundation quality problems. This ensures the safety of the engineering structure from the source. Traditional pile foundation quality testing often uses destructive methods such as "core sampling," which requires repair of the pile foundation after testing and consumes a lot of manpower and resources. In contrast, non-destructive testing devices can directly perform batch testing on all pile foundations without damaging them, greatly reducing repair costs and material waste. This is especially suitable for large-scale infrastructure projects.

[0003] Most non-destructive testing devices for pile foundation integrity on the market require manual positioning, which is quite troublesome. Inaccurate positioning can lead to a discrepancy between the actual defect location and the location displayed by the test. This can cause subsequent repair work to be carried out in the wrong location, which not only fails to solve the problem but may also cause additional operations due to excessive excavation and reinforcement of non-defective areas. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a non-destructive testing device for pile foundation integrity, which aims to improve the problem that the testing device requires manual positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing device for pile foundation integrity, comprising a base, a support frame fixedly connected to the upper surface of the base, a rotary valve rotatably connected to the outside of the support frame, a threaded rod fixedly connected to the outside of the rotary valve, both ends of the threaded rod rotatably connected to the inside of the support frame, a fixing plate threadedly connected to the outside of the threaded rod, a slide rail first provided inside the support frame, a slider fixedly connected to the upper surface of the fixing plate, the slider slidably connected to the inside of the slide rail first, and a positioning component installed on the outside of the fixing plate.

[0006] Preferably, the positioning component includes a horizontal rod, a horizontal plate slidably connected to the outside of the horizontal rod, a telescopic rod one fixedly connected to the bottom end of the horizontal plate, a housing fixedly connected to the outside of the telescopic rod one, a display fixedly connected to the outside of the horizontal rod, a telescopic rod two fixedly connected to the outside of the display, and a probe fixedly connected to the bottom end of the telescopic rod two.

[0007] Preferably, a motor is fixedly connected inside the housing, and the output end of the motor is connected to a slide rail.

[0008] Preferably, a moving column is slidably connected to the outside of the slide rail, and a hammer block is fixedly connected to the bottom end of the moving column.

[0009] Preferably, the base has a second slide rail inside, and a locking block is slidably connected inside the second slide rail.

[0010] Preferably, the card block is externally fixedly connected to a caliper, and the caliper is externally fixedly connected to an anti-slip sand block.

[0011] Preferably, the caliper is externally fixedly connected to a connecting block.

[0012] Preferably, the connecting block has a tightening screw connected to its internal thread.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when it is necessary to position the detection equipment, rotating the rotary valve drives the threaded rod to rotate, causing the horizontal plate to move back and forth inside the slide rail one. Pulling the horizontal plate causes it to move left and right on the horizontal rod. Telescopic rod one and telescopic rod two control the detection device to move up and down, so that the detection device can move back and forth, left and right in the horizontal direction and move up and down, thereby achieving the purpose of positioning the pile foundation by the detection device.

[0015] 2. In this utility model, when the detection device needs to be fixed, push the caliper inward so that the connected caliper block slides inside the slide rail two. After the anti-slip sand blocks on both sides are tightly attached to the pile foundation, rotate the tightening screw to fix the caliper in shape, so as to firmly fix the pile foundation.

[0028] Specifically, when it is necessary to locate the detection equipment, rotating the rotary valve 3 drives the threaded rod 4 to rotate, causing the horizontal plate 82 to move back and forth inside the slide rail 6. Pulling the horizontal plate 82 makes it move left and right on the horizontal rod 81. The telescopic rod 83 and the telescopic rod 86 control the detection device to move up and down, so that the detection device can move horizontally back and forth, left and right, and up and down, to achieve the purpose of locating the pile foundation.

[0030] Specifically, when the motor 9 is running, the slide rail rod 10 at the output end rotates, and the moving column 11 sliding on its surface slides along the slide rail, carrying the hammer block 12 in a cyclic reciprocating motion, so as to achieve the purpose of detection without human intervention to strike the pile foundation.
