Description

Technical Field

[0001] This utility model relates to the technical field of pile foundation hole formation quality inspection device, specifically a pile foundation hole formation quality inspection device. Background Technology

[0002] A pile foundation hole forming quality inspection device disclosed in CN218862592U includes a placement plate; a rotating shaft is rotatably connected to the inner side of the placement plate; a connecting line is fixedly connected to the surface of the rotating shaft; an infrared detector is fixedly connected to the end of the connecting line away from the rotating shaft; a limit ring and a connecting ring are fixedly connected to the surface of the rotating shaft; a circular groove is evenly formed on the top surface of the connecting ring; and a support plate is fixedly connected to the top of the placement plate.

[0003] The process involves placing a support plate on the borehole and positioning the infrared detector close to the center of the borehole. Then, the limiting rod is pulled to slide out of the circular groove. The connecting wire is then held by hand while the shaft is rotated to release the connecting wire from the shaft. At this point, the infrared detector will slowly descend, preventing it from colliding with the bottom of the borehole due to an unexpectedly rapid descent.

[0004] The technical solution in the prior art has the effect of descent at a constant speed to avoid impact caused by excessive speed. However, during the descent at a constant speed, it cannot automatically reduce speed when the infrared detector approaches the bottom wall of the pile hole, nor can it buffer kinetic energy when the infrared detector contacts the bottom wall of the pile hole. The impact caused by the descent at a constant speed will still damage the infrared detector in the long run. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pile foundation hole formation quality inspection device, which solves the problem that during uniform descent, the device cannot automatically slow down when the infrared detector approaches the bottom wall of the pile hole, and cannot buffer kinetic energy when the infrared detector contacts the bottom wall of the pile hole.

[0011] In a specific embodiment, the bottom ring pushes the slide pipe to move upward along the slide rod when the bottom ring contacts the bottom wall in the pile hole, and the slide pipe compresses the spring to absorb the impact force of the infrared detection structure when the slide pipe moves upward.

[0012] In a specific embodiment, the pull rod drives the clamping column to disengage from the positioning hole of the extension rod when the pull rod slides along the sliding groove of the sleeve, and the small spring drives the clamping column to insert into the positioning hole of the extension rod to lock the extension length of the extension rod when the small spring resets.

[0013] Compared with the prior art, the pile foundation hole forming quality inspection device has the following beneficial effects:

[0025] The wire releasing assembly 6 comprises a clamping plate 61 fixedly connected to the bottom surface of the sleeve 4, the surface of the clamping plate 61 is rotationally connected with a take-up reel 62, the side surface of the clamping plate 61 is fixedly connected with a drive motor 63 for fixing the take-up reel 62, the surface of the take-up reel 62 is fixedly connected with an infrared detection structure 64 through a connecting rope, the surface of the infrared detection structure 64 is sleeved with an upper ring 65, the bottom surface of the upper ring 65 is fixedly connected with a slide rod 66 in a rectangular array, the bottom surface of the slide rod 66 is fixedly connected with a spring 67, the bottom surface of the spring 67 is fixedly connected with a slide pipe 68, and the bottom surface of the slide pipe 68 is fixedly connected with a bottom ring 69. In the embodiment, the slide rod 66 is slidingly connected with the slide pipe 68, the spring 67 is compressed and deformed when the slide pipe 68 slides along the slide rod 66, and the bottom ring 69 and the bottom surface of the infrared detection structure 64 form a buffer spacing. The drive motor 63 receives the real-time ranging signal of the infrared detection structure 64 through the control panel 5, and when the infrared detection structure 64 detects that the distance from the bottom wall in the pile hole is less than a preset threshold, the control panel 5 triggers the drive motor 63 to run at a reduced speed to slow down the wire releasing speed of the take-up reel 62; when the bottom ring 69 contacts the bottom wall of the pile hole, the slide pipe 68 is pushed to move upward along the slide rod 66, and the slide pipe 68 compresses the spring 67 to form a counteracting force to offset the inertial impact of the infrared detection structure 64; the control panel 5 adopts a Siemens S7-1200 PLC controller which analyzes the laser ranging data of the infrared detection structure 64 through an embedded algorithm and dynamically controls the rotational speed gradient of the drive motor 63; the sliding fit of the slide rod 66 and the slide pipe 68 ensures that the bottom ring 69 moves smoothly in the vertical direction when it is pressed, the elastic deformation of the spring 67 absorbs the instantaneous kinetic energy of the infrared detection structure 64, and the spacing buffer design of the upper ring 65 and the bottom ring 69 realizes double anti-collision protection.

[0027] When the pull rod 34 is pulled horizontally by external force, the sleeve 31 guides the pull rod 34 to drive the clamping column 33 to move upward synchronously, so that the clamping column 33 is separated from the positioning hole of the extension rod 2, and at this time, the extension rod 2 can be freely telescopic to adapt to the diameter of the pile hole; after the external force is released, the small spring 32 in the sleeve 31 pushes the clamping column 33 to press downward and insert into the corresponding positioning hole of the extension rod 2, so that quick locking is realized; the symmetrical design of the pull rod 34 ensures that the clamping column 33 is balanced in the lifting process, and deviation and jamming are avoided; the elastic force of the small spring 32 continuously acts on the clamping column 33, and stable pressure is formed in the locked state, so that the extension rod 2 is prevented from being accidentally retracted during detection; the cooperation mechanism can complete the unlocking, adjusting and locking actions by operating the pull rod 34 with one hand, the sliding groove of the sleeve 31 restricts the movement track of the pull rod 34, and the self-resetting characteristics of the small spring 32 are combined, so that the adjusting efficiency of the extension rod 2 and the adaptability of the device to different pile hole sizes are significantly improved.
