Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying, and more specifically, the utility model relates to a hole detector for bored cast-in-place piles. Background Technique

[0002] Due to its mature construction technology, high bearing capacity and wide application range, bored cast-in-place piles have been widely used in the foundations of structural projects such as highways and railway bridges. For large, medium and small bridges and interchange bridges on high-grade highways, bored cast-in-place piles are basically adopted. After the bored cast-in-place pile hole is formed, according to the requirements of design and specifications, a crane is used to lower the hole detector for bored cast-in-place piles into the formed pile hole. The hole detector is a device used to detect the diameter and verticality of the formed hole before the construction of cast-in-place concrete piles.

[0003] In the use process of the existing common hole detectors for bored cast-in-place piles, if there are multiple pile hole diameters, it is necessary to manufacture hole detectors with different diameters for detection, which is more wasteful of materials, and relatively time-consuming in selecting the hole detector with the same diameter as the pile hole.

[0004] Therefore, a hole detector for bored cast-in-place piles is proposed to solve the above problems. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a hole detector for bored cast-in-place piles to solve the problems put forward in the above background technique.

[0007] A main rod is fixedly connected to the central part of the hanging shell body. A first adjusting component is nested and installed on the outer wall of the upper part of the main rod, and a second adjusting component is nested and installed under the main rod. An electric push rod is fixedly installed at the outer end of the first adjusting component. One end of the electric push rod is fixedly connected to a fixed block, and one end of the fixed block is fixedly connected to a detection rod. A connecting piece is fixedly connected under the first adjusting component. The outside of the connecting piece is movably connected to a first rotating plate. One end of the first rotating plate is embedded and connected with a first rotating shaft. The other end of the first rotating plate is movably connected to a second rotating plate. One end of the second rotating plate is embedded and connected with a second rotating shaft. The other end of the second rotating plate is movably connected to a third rotating plate. One end of the third rotating plate is embedded and connected with a third rotating shaft. The other end of the third rotating plate is embedded and connected with a fourth rotating shaft. One end of the detection rod is fixedly connected to a support block.

[0008] Furthermore, a hanging ring is fixedly connected to the top of the main rod.

[0009] Further, there are two sets of the electric push rods, and each set has six electric push rods. The six electric push rods are arranged equidistantly around the first adjustment component and the second adjustment component for one week.

[0010] Further, the cross-sectional shapes of the first rotating plate, the second rotating plate and the third rotating plate are all rectangular, and the cross-sectional dimension of the third rotating plate is larger than those of the first rotating plate and the second rotating plate.

[0011] Further, there are six detection rods in total, and the six detection rods are arranged around the main rod as the axis.

[0012] Further, the cross-sectional shapes of the detection rod and the main rod are both cylindrical, and the length of the detection rod is greater than that of the main rod.

[0023] Embodiment 1

[0024] As shown in the attached Figures 1-4 A hole detector for bored cast-in-place piles shown in the figure includes a hanging shell body 1;

[0025] The central part of the hanging shell body 1 is fixedly connected with a main rod 2. The outer wall of the upper part of the main rod 2 is nested with a first adjusting component 3. The lower part of the main rod 2 is nested with a second adjusting component 4. The outer end of the first adjusting component 3 is fixedly installed with an electric push rod 5. One end of the electric push rod 5 is fixedly connected with a fixed block 6. One end of the fixed block 6 is fixedly connected with a detection rod 14. The lower part of the first adjusting component 3 is fixedly connected with a connecting piece 7. The outside of the connecting piece 7 is movably connected with a first rotating plate 8. One end of the first rotating plate 8 is embedded with a first rotating shaft 9. The other end of the first rotating plate 8 is movably connected with a second rotating plate 10. One end of the second rotating plate 10 is embedded with a second rotating shaft 11. The other end of the second rotating plate 10 is movably connected with a third rotating plate 12. One end of the third rotating plate 12 is embedded with a third rotating shaft 13. The other end of the third rotating plate 12 is embedded with a fourth rotating shaft 16. One end of the detection rod 14 is fixedly connected with a support block 15.

[0026] Among them: When in use, the whole device is lowered into the pile hole. During the lowering process, the distance between the detection rod 14 and the main rod 2 can be adjusted according to the diameter inside the pile hole. By turning on multiple electric push rods 6, the detection rod 14 can be pushed to expand or contract. During the movement of the detection rod 14, the first rotating plate 8 rotates under the action of the first rotating shaft 9, and then drives the second rotating plate 10 and the third rotating plate 12 to rotate in sequence, so as to adjust the distance between the detection rod 14 and the main rod 2. After the detection is completed, the detection rod 14 can be contracted under the action of the contraction of the electric push rod 5, so as to avoid the hanging shell body 1 occupying too much space.

[0027] Embodiment 2

[0028] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods. For details, see the following description:

[0029] As Figure 2 shown, as a preferred embodiment; a lifting ring 17 is fixedly connected to the top of the main rod 2. Further, by fixing the lifting crane to the lifting ring 17, the entire device can be lowered into the pile hole.

[0030] The working process of the present utility model is as follows:

[0031] When using this kind of borehole cast-in-place pile hole detector, the entire device is lowered into the pile hole. During the lowering process, the distance between the detection rod 14 and the main rod 2 can be adjusted according to the inner diameter of the pile hole. By activating multiple electric push rods 6, the detection rod 14 can be pushed to expand or contract. During the movement of the detection rod 14, the first rotating plate 8 rotates under the action of the first rotating shaft 9, and then drives the second rotating plate 10 and the third rotating plate 12 to rotate successively, so as to adjust the distance between the detection rod 14 and the main rod 2. After the detection is completed, the detection rod 14 can be contracted under the action of the contraction of the electric push rod 5, which can avoid the over-large occupation of space by the hanging shell body 1. This is the working process and working principle of this device.
