[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As attached Figure 1 As shown, the pile hole diameter detection device to be protected by the utility model includes a device body 1, a control console 2 located at the upper end of the device body 1 and capable of controlling the electronic components and electrical components in the device body 1, and a detection structure located below the device body 1 and used for penetrating into the pile hole to realize pile hole diameter measurement.

[0029] The aforementioned detection structure includes a telescopic rod 11, which has an extension part and a base part. The base part of the telescopic rod 11 is connected to a power part for driving the telescopic rod 11. Driven by the power part, the extension part of the telescopic rod 11 is extended or retracted in the base part.

[0030] As an embodiment of the utility model, a hydraulic pump 12 is connected to the bottom end of the telescopic rod 11, and the hydraulic pump 12 has one or two ends; when the hydraulic pump 12 has one end, a hydraulic cylinder is connected to the hydraulic pump 12, and an inner cavity 5 is provided in the device body 1, and a power oil tank 7 is installed in the inner cavity 5. The hydraulic pump 12 obtains energy from the power oil tank 7 through an oil pipe 10 connected to the power oil tank 7 and controls the first movable column 13 to realize telescopic movement in the aforementioned hydraulic cylinder after conversion; a first wall-adhering arc block 14 that adheres to the inner wall of the pile hole is provided at the front end of the first movable column 13; at this time, the aforementioned power oil tank 7 stores hydraulic oil sufficient for the first movable column 13 to realize telescopic workmanship, and the power oil tank 7 and the hydraulic pump 12 pass therethrough.

[0031] In order to improve the measurement accuracy of the device, the first wall-adhering arc block 14 is detachably arranged at the upper end of the first movable column 13, and the detachable implementation methods include but are not limited to snaps, threads and concave-convex connections; in order to improve the detection fit of the device, the first wall-adhering arc block 14 should have different specifications, and the first wall-adhering arc blocks 14 of different specifications have the same thickness; a wireless pressure sensor is embedded in the first wall-adhering arc block 14, and when the first wall-adhering arc block 14 detects the generation of pressure, it sends an electrical signal to the PLC located in the console 2, and the PLC controls the first movable column 13 to stop working.

[0032] When in use, the user first connects the device to an external control power supply, places the device body 1 above the pile hole of the aperture to be detected, and the lower edge position of the device body 1 contacts the upper surface of the pile hole. At this time, the hydraulic pump 12 and the first movable column 13 located at one end thereof are located within the aperture of the pile hole, and one end of the hydraulic pump 12 is attached to the inner wall of the pile hole. The inner wall of the pile hole attached to the hydraulic pump 12 is defined as point one. At this time, the user controls the first movable column 13 to extend through the control console 2. The movement of the first movable column 13 drives the first wall-attached arc block 14 to move at the same time. The first wall-attached arc block 14 moves toward the inner wall corresponding to the inner wall one. The inner wall corresponding to the inner wall one is defined as point two. The first wall-attached arc block 14 will gradually approach point two during the movement until the first wall-attached arc block 14 is attached to point two and is located opposite to the first wall-attached arc block 14. When the pressure sensor on the surface of block 14 detects the generation of pressure, it sends an electrical signal to the PLC, and the PLC controls the first movable column 13 to stop moving. At the same time, the displacement sensor arranged at the combination position of the hydraulic pump 12 and the first movable column 13 detects the displacement distance of the first movable column 13 in real time, and transmits the data detected by the displacement sensor to the PLC in real time. The PLC displays the value through the display screen 4 located on the control console 2. After the first movable column 13 stops moving, the value on the display screen 4 no longer changes. At this time, the value displayed by the displacement sensor is the moving distance of the first movable column 13 from the combination position of the first movable column 13 and the hydraulic pump 12 to point two; the sum of the moving distance, the thickness of the first wall-attached arc block 14 and the length of the hydraulic pump 12 is the value of the inner diameter of the pile hole.

[0033] As a further improved embodiment of the above embodiment, different from the above embodiment, the hydraulic pump 12 has two ends, and a hydraulic cylinder is connected to each end respectively. A movable column is retractably driven in each hydraulic cylinder, one of the movable columns is a first movable column 13, and the other movable column is a second movable column 15. As in the above embodiment, the front end of the first movable column 13 is a detachable first wall-attached arc block 14, and the front end of the second movable column 15 is coupled with the second wall-attached arc block 16. Since the two hydraulic cylinders are supplied with oil through the power oil tank 7, the oil demand of the power oil tank 7 becomes larger. In order to improve the overall energy supply stability of the device, the power oil tank 7 and the oil pump 6 are sealed through the connecting pipe 8. The oil delivery of the oil pump 6 is sufficient for the detection structure contained in the device to realize detection.

[0034] When in use, the user connects the device to an external control power supply to obtain power, and then places the device body 1 on a surface with a detection aperture. At this time, the hydraulic pump 12, the first movable column 13, and the second movable column 15 are all located in the aperture. At this time, as shown in the attached Figure 4As shown, the first movable column 13 is driven by the hydraulic pump 12 to move in one direction, which is defined as direction a. At the same time, the hydraulic pump 12 drives the second movable column 15 to move in a direction b opposite to direction a, until the first wall-adhering arc block 14 and the second wall-adhering arc block 16 are respectively attached to the inner wall of the pile hole. At this time, the moving distance of the first movable column 13 and the moving distance of the second movable column 15 are both displayed on the display screen 4. The moving distance of the first movable column 13, the moving distance of the second movable column 15, the length of the hydraulic pump 12, the thickness of the first wall-adhering arc block 14 and the second wall-adhering arc block 16 are added together to obtain the aperture value.

[0035] Combination Figure 2 and Figure 3 In order to improve the protection performance of the console 2, the console 2 is arranged in a recessed shape on the upper surface of the device body 1, and a sealing cover 3 is connected to the top of the console 2 through a hinge in an openable and closable manner. A lock body 32 that can lock the sealing cover 3 is provided on the device body 1, and a handle 31 is provided on the sealing cover 3 for the user to collect or carry the device.

[0036] At the same time, the device can control the extension and retraction of the telescopic rod 11 located at the upper end of the hydraulic pump 12 through the driving motor 9. When the telescopic rod 11 is extended, the hydraulic pump 12 can be driven to any depth in the pile hole, so that the hydraulic pump 12 can measure the aperture, which is convenient for the user to obtain the aperture difference at various depths.

[0037] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
