[0035] like Figure 1-Figure 5 As shown together, the pile hole diameter detection device proposed in this embodiment can be used to detect the inner diameters of cast-in-place piles with various hole diameters, and can also be used to measure the hole diameters in other occasions.

[0036] The pile hole diameter detection device comprises a central support 1 and a measuring component 2. The central support 1 is used to adjustably connect the measuring component 2 and support the measuring component 2 to penetrate into the pile hole. The measuring component 2 can form a cylindrical shape with different diameters and is used to measure whether pile holes with different diameters are qualified.

[0039] In order to be adjustably connected with the measuring component 2 and adapt to pile holes of different diameters, plug-ins 12 are evenly arranged from top to bottom on the middle rod 11, and each group of plug-ins 12 includes connecting pipes 121 evenly arranged around the outer wall of the middle rod 11. The connecting pipes 121 are all in the same plane, and the through holes 122 evenly arranged on the connecting pipes 121 are used for adjustably connecting with the measuring component 2.

[0040] In order to form a stable cylindrical detection device and enable the measuring assembly 2 to penetrate into a deeper pile hole with a poor environment without deformation, the measuring assembly 2 is configured to be composed of several measuring parts. The measuring assembly 2 may include an end measuring part 22 and a rod measuring part 21. The rod measuring part 21 includes a first strip plate 211 and a first connecting rod 212 vertically connected to the middle of the first strip plate 211. The end measuring part 22 includes a second strip plate 221 and a second connecting rod 222 vertically connected to one end of the second strip plate 221. Perforations are evenly arranged on the first connecting rod 212 and the second connecting rod 222, respectively. The spacing of the perforations is the same as the spacing of the through holes 122 on the connecting pipe 121, and the inner diameter of the perforations is the same as that of the through holes 122.

[0041] For easy installation, the axis of the through hole 122 is parallel to the axis of the middle rod 11. The center axis of the through hole is parallel to the length center line of the first strip plate 211 / the second strip plate 221.

[0042] The end measuring piece 22 is used to be installed at both ends of the center bracket 1, and the rod measuring piece 21 is used to be installed on the center bracket 1. In order to facilitate the penetration into the pile hole, the second strip plate 221 of the end measuring piece 22 is connected to the second connecting rod 222 in an L shape. The second connecting rod 222 is inserted into the connecting tube 121 at the end of the intermediate rod 11. The insertion length of the second connecting rod 222 is adjusted according to the measurement needs, the through hole 122 is aligned with the perforation, and the pin 3 is inserted to fix the second connecting rod 222 and the connecting tube 121. In order to fix and stabilize, multiple pins 3 can be inserted. Several second strip plates 221 are firmly around the intermediate rod 11. The pin 3 can be bolted and fastened by nuts.

[0043] In order to measure the stability of the structure, the first strip plate 211 of the rod measuring piece 21 is connected to the first connecting rod 212 in a T-shape, and the width of the first strip plate 211 is the same as that of the second strip plate 221. The first connecting rod 212 is inserted into the connecting tube 121 in the middle of the middle rod 11. The insertion length of the first connecting rod 212 is adjusted according to the measurement needs, the through hole 122 is aligned with the perforation, and the pin 3 is inserted to fix the first connecting rod 212 and the connecting tube 121. For stability, multiple pins 3 can be inserted. Several first strip plates 211 are firmly around the middle rod 11. After the first strip plate 211 is installed, it is aligned and close to the adjacent second strip plate 221.

After assembly, the strip plates on the same straight line can form a long board.

[0046] In a specific embodiment of the utility model, in order to prevent the strip plates from being deformed during long-term use, the length of the strip plates can be appropriately shortened. According to the length of the first strip plates 211, the plug-ins 12 are evenly arranged on the rod portion of the middle rod 11, and there can be at least two groups of the plug-ins 12.

All the first strip plates 211 and the second strip plates 221 are surrounded on the same cylinder.

[0047] In a specific embodiment of the present invention, the number of connecting tubes 121 of a group of plug-ins 12 is greater than 4, and in this embodiment, 8 are used. A larger number of connecting tubes 121 can connect more strip plates, and the shape formed by more strip plates is closer to a cylinder, which makes it more convenient and accurate to put it into a deep hole for inspection.

[0048] In a specific embodiment of the present invention, in order to firmly and stably secure the connecting tube 121 of the plug 12, the plug 12 further comprises a ring plate 123 connected to the connecting tube 121 of one circle, and the end of the connecting tube 121 away from the middle rod 11 passes through the ring plate 123. The ring plate 123 is connected to the outer end of the connecting tube 121 of one circle, and the outer end position of the connecting tube 121 of one circle is fixed and stabilized, so as to prevent the connecting tube 121 from horizontal deformation and dislocation.

[0049] In a specific embodiment of the present invention, in order to prevent the plug-in 12 from deforming up and down, support rods 13 are evenly connected between adjacent ring plates 123. The number of support rods 13 can be four, and the four support rods 13 are supported between adjacent ring plates 123 to prevent the plug-in 12 from deforming up and down, so as not to affect the verticality of the first and second connecting plates.

The outer ends of the reinforcement rods 15 are commonly connected to reinforcement rings 16, and oblique rods 17 are evenly connected between the reinforcement rings 16 and the adjacent ring plates 123.

[0051] Both ends of the middle rod 11 are truncated cone-shaped, which is convenient for being placed in the hole. A reinforcing rod 15 is arranged at the end of the end rod 14. The reinforcing rod 15 is shorter than the connecting tube 121. The outer ends of the reinforcing rods 15 are connected together by reinforcing rings 16 to prevent the reinforcing rods 15 from deforming horizontally. The number of inclined rods 17 can be four, and the four inclined rods 17 are supported between the reinforcing ring 16 and the ring plate 123 to prevent the reinforcing ring 16 from deforming up and down. The end rods 14 at both ends can be used for hoisting, and the ends are firm.

[0052] In a specific embodiment of the utility model, a lifting ring 4 may be provided on the end rod 14. A steel ring is connected to the end of the end rod 14 to facilitate lifting by a crane.

[0053] In a specific embodiment of the utility model, an inclined plate 223 may be connected to the end of the second strip plate 221 connected to the second connecting rod 222, and after the second connecting rod 222 is connected to the connecting pipe 121, the inclined plate 223 is parallel to the reinforcing rod 15. The end measuring piece 22 is composed of the inclined plate 223 and the second strip plate 221, and the inclined plate 223 transitions to the vertical second strip plate 221, which helps the entire device to be smoothly placed in the pile hole.

[0054] The utility model is firmly welded and rust-proofed, and can be put into a deeper hole to check whether the hole diameter at any position is qualified. If it is lowered smoothly, the hole diameter is qualified; if it is lowered by an obstacle, the hole diameter at the obstacle is unqualified.

[0055] The length of the middle rod 11 is set according to the needs of the construction. Generally, the length of the middle rod 11 is 4-6 times the diameter of the pile hole to ensure stable lowering. The inner diameter of the pile hole in a project is different from 1.2m to 1.8m. In order to adapt to different pile holes, the middle rod 11 is set to about 7.2m in this embodiment, and a steel pipe with an outer diameter of 8cm and a wall thickness of 1cm is used.

[0056] The outer diameter of the plug 12 can be about 1m, which meets the outer diameter of the adjustment measuring assembly 2. The outer diameter of the reinforcement ring 16 can be 0.5m.
