Description

Technical Field

[0001] The utility model relates to a hole quality control device for rotary drilling and bored piles, belonging to the technical field of bored piles. Background Art

[0002] Bored piles are a type of pile made by drilling holes in place and pouring concrete or reinforced concrete. Auger drills, submersible drills, etc. are often used to dig holes on site and pour concrete into the piles. Bored piles have the advantages of high bearing capacity, low construction noise, low vibration and low unit price. They are now widely used in various engineering buildings such as foundation pit support, bridges, municipal administration, and highways. Bored piles are cast in place underground, and the pouring quality is difficult to ensure. Therefore, before pouring, it is necessary to drive a conduit into the ground hole, put a steel cage and pour concrete from the upper port of the conduit, and set a multi-layer ultrasonic detection head vertically on the outer wall of the conduit for quality inspection.

[0003] Publication No.: CN207633331U, mentions a bored cast-in-place pile quality control device. After the device is laid out and the conduit is lowered, before pouring concrete, multiple sets of sensor devices arranged along the concrete conduit can detect whether the steel cage is deformed, the main reinforcement spacing, the stirrup spacing, etc. As the concrete conduit is continuously lifted during the pouring process, the multiple sets of sensor devices arranged along the concrete conduit can detect the depth of the conduit inserted into the concrete surface, the pile body diameter, the pile body verticality, etc. However, the sensor device in the device is manually installed and fixed, which is inconvenient. At the same time, the detection position is fixed, which is inconvenient to perform all-round detection of the internal concrete density. Now a rotary bored cast-in-place pile hole quality control device is urgently needed to solve the above-mentioned problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a device for controlling the quality of bored pile holes, comprising an outer protective shell, a guide tube, an annular seat and a forward and reverse motor, a bucket-shaped fixing frame is installed at the upper end of the inner part of the outer protective shell, the guide tube is inserted into the inner side of the outer protective shell and the bucket-shaped fixing frame, a plurality of electric telescopic rods are fixed at equal angles inside the bucket-shaped fixing frame, the annular seat is located on the inner side of the outer protective shell, a conical ring is arranged on the inner side of the annular seat, an annular frame is installed on the lower end of the annular seat by bolts, an annular slide is fixed on the inner side of the annular frame, a rotating detection seat is installed on the upper end of the annular slide by a plurality of ball bearings, a plurality of ultrasonic detection sensor heads are installed at the same angles on the upper end of the rotating detection seat, an annular gear is fixed on the outer side of the rotating detection seat, the forward and reverse motor is installed on the left side of the upper end of the annular seat, and the shaft end of the forward and reverse motor passes through the annular seat and is fixed to the transmission gear.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a device for controlling the quality of bored piles, comprising an outer casing 1, a guide tube 2, an annular seat 6 and a forward and reverse motor 14. A bucket-shaped fixing frame 4 is installed at the upper end of the inner part of the outer casing 1. The guide tube 2 is inserted into the inner side of the outer casing 1 and the bucket-shaped fixing frame 4. A plurality of electric telescopic rods 5 are fixed at equal angles inside the bucket-shaped fixing frame 4. The annular seat 6 is located inside the outer casing 1. A conical ring 7 is arranged inside the annular seat 6. An annular frame 8 is installed at the lower end of the annular seat 6 by bolts. An annular sliding seat 9 is fixed inside the annular frame 8. A rotating detection seat 11 is slidably installed on the upper end of the annular slide 9 through multiple balls 10, and multiple ultrasonic detection sensor heads 15 are installed at equal angles on the upper end of the rotating detection seat 11. A ring gear 12 is fixed to the outside of the rotating detection seat 11, and a forward and reverse motor 14 is installed on the left side of the upper end of the annular seat 6. The shaft end of the forward and reverse motor 14 passes through the annular seat 6 and is fixed to the transmission gear 13. This design solves the problem that multiple sets of sensor devices in the original device are manually installed and fixed, which is inconvenient, and the detection position is fixed, which makes it inconvenient to conduct all-round detection of the internal concrete density.

[0019] As the first embodiment of the utility model: a pouring bucket 3 is integrally installed on the upper end of the conduit 2, and the pouring bucket 3 is placed on the inner side of the bucket-shaped fixing frame 4. The added bucket-shaped fixing frame 4 can provide auxiliary support for the pouring bucket 3, so that the pouring bucket 3 is installed more stably. The set pouring bucket 3 facilitates the injection of concrete into the conduit 2.

[0020] The movable ends of the multiple electric telescopic rods 5 are fixed to the annular seat 6 by bolts and flanges, and the added multiple electric telescopic rods 5 can drive the annular seat 6 to rise and fall. The conical ring 7, the annular slide 9 and the rotating detection seat 11 are sleeved on the outside of the catheter 2, and the conical ring 7, the annular slide 9 and the rotating detection seat 11 slide against the outer wall of the catheter 2. Through the added conical ring 7, the burrs on the outer surface of the catheter 2 can be scraped off when the catheter 2 is installed in the outer casing 1. The transmission gear 13 meshes and rotates with the annular gear 12. When the added transmission gear 13 rotates, the annular gear 12 and the rotating detection seat 11 can be driven to rotate accordingly.

[0021] As a second embodiment of the utility model: when the catheter 2 is inserted into the outer protective shell 1, the bucket-shaped fixing frame 4 can guide it, and the added conical ring 7 can scrape off the burrs on the outer surface of the catheter 2 when the catheter 2 is installed in the outer protective shell 1 until the catheter 2 is completely installed in the outer protective shell 1. At this time, the bucket-shaped fixing frame 4 can assist in supporting the pouring bucket 3, and then concrete can be poured into the catheter 2. During this process, multiple electric telescopic rods 5 are started, and the movable ends of the electric telescopic rods 5 drive the annular seat 6 to move downward, thereby causing the conical ring 7, the annular frame 8, the annular slide seat 9, the rotating detection seat 11, the annular gear 12, the transmission gear 13, the forward and reverse motors 14 and the multiple ultrasonic detection sensor heads 15 to move downward, and the multiple ultrasonic detection sensor heads 15 are started at the same time. A plurality of ultrasonic detection sensor heads 15 can detect the density of the concrete inside the conduit 2, and then control the shaft end of the forward and reverse motor 14 to rotate forward and reverse one circle, and the shaft end of the forward and reverse motor 14 can drive the transmission gear 13 to rotate forward and reverse one circle, so that the annular gear 12 meshes with it and rotates forward and reverse one circle. At this time, the rotating detection seat 11 will also be driven to rotate forward and reverse one circle (due to the setting of multiple balls 10, the annular slide seat 9 will not rotate at this time), so that the plurality of ultrasonic detection sensor heads 15 moving downward will rotate forward and reverse one circle, and then the density of the concrete inside can be fully detected through the conduit 2 (Note: the circuits and electronic components involved in the utility model are all existing technologies, which can be fully realized by those skilled in the art, and there is no need to elaborate. The content protected by the utility model does not involve improvements to software and methods).
