[0002] Probe cages are commonly used auxiliary tools in building construction. They are cage-shaped structures used to inspect the condition of pile holes during pile foundation construction. However, most probe cages require the use of guide rods or other structures to inspect the diameter of the pile holes, resulting in a narrow inspection range. Utility Model Content

[0003] This application mainly provides a pile hole detection cage and detection device, which has a simple structure, is easy to use for detection, and has comprehensive detection functions.

[0004] According to a first aspect of this application, this application provides a pile hole detection probe cage, comprising:

[0005] The probe cage body is used to be lowered or moved up along a direction coaxial with the pile hole;

[0006] A verticality detection unit is provided, which is set at a preset position on the probe cage body, and is used to detect the verticality of the pile hole.

[0007] A borehole detection unit is disposed on the outer periphery of the probe cage body and is used to detect the borehole diameter of the pile hole.

[0008] In one embodiment, the verticality detection unit includes at least one tilt sensor, and the preset position is the top end, and / or bottom end, and / or center of the probe cage body.

[0009] In one embodiment, the tilt sensor is provided at the top, bottom and center of the probe cage body.

[0010] In one embodiment, the aperture detection unit includes a measuring arm and a displacement sensor. The displacement sensor is installed on the outer periphery of the probe cage body.

[0011] In one embodiment, the aperture detection unit further includes an elastic element, and the measuring arm is connected to the outer periphery of the probe cage body through the elastic element, the elastic element being used to reset the measuring arm.

[0012] In one embodiment, the length of the probe cage body is 3 to 5 times the diameter of the pile hole.

[0022] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0023] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0024] See Figure 1 As shown, the pile hole detection cage 100 provided in this application includes a cage body 10, a discharge detection unit 20, and a hole diameter detection unit 30.

[0025] The probe cage body 10 is used to lower or move upward along the coaxial direction with the pile hole. Specifically, the probe cage body 10 is lowered to a preset position along the coaxial direction with the pile hole by a hoisting device to ensure that the probe cage body 10 can be completely inserted into the pile hole.

[0026] The cage body 10 includes multiple vertical ribs 11 and spiral ribs 12. The multiple vertical ribs 11 are arranged in sequence with equal circumferences. The spiral ribs 12 are wrapped around the multiple vertical ribs 11 and are fixedly connected to the multiple vertical ribs 11 by binding, welding or other methods.

[0027] The verticality detection unit 20 is set at a preset position on the probe cage body 10, and the verticality detection unit 20 is used to detect the verticality of the pile hole.

[0028] The aperture detection unit 30 is set on the outer periphery of the probe cage body 10, and the aperture detection unit 30 is used to detect the aperture of the pile hole.

[0029] In this application, a verticality detection unit 20 is installed at a preset position on the probe cage body 10. After the probe cage body 20 is installed into the pile hole, if the pile hole is skewed, the probe cage body 10 will also skew. Therefore, by detecting the verticality of the probe cage body 10 through the verticality detection unit 20, the detection function of the pile hole can be indirectly achieved. The hole diameter detection unit 30 is located on the outer periphery of the probe cage body 10, enabling the detection of the pile hole diameter. Compared with related technologies that rely on other auxiliary structures for detection, this pile hole detection probe cage 100 has a simpler structure and more comprehensive detection functions.

[0030] The verticality detection unit 20 includes at least one tilt sensor, with preset positions at the top, and / or bottom, and / or center of the probe cage body 10. In this embodiment, two tilt sensors are provided, with preset positions at the top and bottom of the probe cage body 10. The two tilt sensors are respectively located at the top and bottom of the probe cage body 10 to improve the accuracy of the detection results.

[0031] In one embodiment, tilt sensors are provided at the top, bottom and center of the probe cage body 10. Of course, tilt sensors may also be provided only at the center of the probe cage body 10.

[0032] like Figure 2 As shown, the aperture detection unit 30 includes a measuring arm 31 and a displacement sensor 32. The displacement sensor 32 is installed on the outer periphery of the probe cage body 10, specifically connected to the outer periphery of the probe cage body 10 through other support structures. One end of the measuring arm 31 is slidably installed on the probe cage body 10, and the other end of the measuring arm 31 extends to the outside of the probe cage body 10. The measuring arm 31 is used to contact the hole wall of the pile hole, and the displacement sensor 32 is used to detect the displacement of the measuring arm 31.

[0033] Specifically, the radial dimension of the probe cage body 10 is smaller than the diameter of the pile hole. The pile hole is drilled with a set diameter. In the initial state, the measuring arm 31 extends from the end of the measuring arm 31 to the center of the probe cage body 10 to the outside of the probe cage body 10. The length of the measuring arm 31 is a preset length. This preset length should be greater than the radius of the pile hole. After the probe cage body 10 is in place, the measuring arm 31 will be displaced. The displacement sensor 32 detects the amount of displacement. The difference between the preset length and the detected amount can be used to obtain the current diameter of the pile hole, thus completing the measurement of the pile hole diameter.

[0034] In this embodiment, multiple aperture detection units 30 are arranged along the height direction of the probe cage body 10. When different aperture detection units 30 detect different apertures, they can also indirectly reflect the verticality of the pile hole.

[0035] See also Figure 2 As shown, the aperture detection unit 30 also includes an elastic element 33. The measuring arm 31 is connected to the outer periphery of the probe cage body 10 through the elastic element 33. The elastic element 33 is used to reset the measuring arm 31, which has been displaced, to its initial position.

[0036] In this embodiment, the length of the probe cage body 10 is 3 to 5 times the diameter of the pile hole, combined with... Figure 3 As shown, the radial dimension of the probe cage body 10 is 5cm-10cm smaller than the diameter of the pile hole.

[0037] See Figure 1 and Figure 4As shown, the two ends of the probe cage body 10 are cones, which can guide the probe cage body 10 when it is lowered or moved up.

[0038] This application also provides a pile hole detection device, including the pile hole detection probe cage 100 in the above embodiments. For the specific structure and features of the pile hole detection probe cage 100, please refer to the above embodiments.

[0039] In summary, the pile hole detection cage and detection device provided in this application, by setting a verticality detection unit at a preset position on the cage body, ensures that if the pile hole is skewed after the cage body is installed, the cage body will also skew. Therefore, by detecting the verticality of the cage body through the verticality detection unit, the pile hole detection function can be indirectly achieved. The hole diameter detection unit, located on the outer periphery of the cage body, can detect the hole diameter. Compared to related technologies that rely on other auxiliary structures for detection, this pile hole detection cage has a simpler structure and more comprehensive detection functions.
