[0028] Example

[0029] Reference Figure 1-Figure 4The utility model provides a technical solution: a hoisting and positioning device for a pile foundation aperture measuring instrument, comprising a mounting frame 1 and a positioning mechanism 3, and a round roller 2 is rotatably arranged at a position inside the mounting frame 1, the positioning mechanism 3 comprises a traction rope 31, the traction rope 31 is wound around the round roller 2, the round roller 2 is arranged into two areas, each area is separately wound with a traction rope 31, a connecting disk 32 is fixedly connected to one end of the traction rope 31, a circular plate 321 is rotatably mounted on the upper surface of the connecting disk 32, and a first distance measuring instrument 322 is fixedly mounted on the circular plate 321, an electric telescopic rod 33 is fixedly mounted at the bottom of the connecting disk 32, and a plug-in rod 331 is fixedly mounted at the telescopic end of the electric telescopic rod 33 for positioning the connecting disk 32.

[0030] In a preferred embodiment, a round rod 4 is fixedly installed inside the round roller 2, one end of the round rod 4 is rotatably connected to the inner wall of the mounting frame 1, and the other end passes through the outside of the mounting frame 1 and is rotatably connected to the inside of the mounting frame 1. In order to facilitate the control of the rotation of the round roller 2, a round rod 4 is fixedly installed inside the round roller 2, and one end of the round rod 4 is installed on the rotating disk 91. By controlling the rotation of the rotating disk 91, the round roller 2 can be driven to rotate, thereby winding and releasing the traction rope 31 to meet the needs of use.

[0031] In a preferred embodiment, a support frame 5 is fixedly installed on the upper surface of the connecting disk 32, a control motor 6 is fixedly installed on the top of the support frame 5, a transmission shaft is installed on the output end of the control motor 6, and the transmission shaft is fixedly connected to the circular plate 321 for driving the circular plate 321 to rotate. In actual use, it is necessary to change the measurement position, measure multiple times, and then take the average value to obtain accurate data for subsequent construction.

[0032] In a preferred embodiment, two first distance measuring instruments 322 are provided and are respectively installed on the upper surface of the connecting plate 32. The two first distance measuring instruments 322 are arranged facing each other. In order to facilitate the measurement of the inner diameter of the pile foundation, the device will provide two first distance measuring instruments 322 and both are installed on the connecting plate 32. The two first distance measuring instruments 322 are arranged back to back and can measure different surfaces, thereby realizing the measurement of the inner diameter of the pile foundation.

[0033] In order to improve the use effect of this device, a positioning plate 7 is fixedly installed on the inner side of the mounting frame 1, and a second distance measuring instrument 8 is fixedly installed on the bottom of the positioning plate 7 for measuring the depth of the pile foundation. When the connecting plate 32 is controlled to move downward, the distance that the connecting plate 32 moves downward will be measured by the second distance measuring instrument 8, so as to detect the distance that the connecting plate 32 moves to meet the use requirements.

[0034] After moving the connecting disk 32, the connecting disk 32 needs to be positioned so that the first distance measuring instrument 322 can be used stably. Therefore, a secondary positioning mechanism 9 is also provided on the outside of the mounting frame 1. The secondary positioning mechanism 9 includes a rotating disk 91, a through hole 92 and a rubber rod 93. The rotating disk 91 is installed at one end of the round roller 2, and a plurality of through holes 92 are opened on the outer surface of the rotating disk 91. The through holes 92 pass through the inner side surface of the rotating disk 91. A fixed block 10 is fixedly installed on the outer surface of the mounting frame 1. A connecting plate 11 is slidably installed inside the fixed block 10. A clamping plate 12 is fixedly installed on one end of the connecting plate 11. A rubber rod 93 is fixedly installed on the inner side surface of the clamping plate 12. The rubber rod 93 is snapped into the inside of the through hole 92.

[0035] In actual use, after determining the position of the connecting disk 32, the connecting plate 11 is moved, and the rubber rod 93 on the clamping plate 12 is clamped into the through hole 92 on the rotating disk 91, and the rotating disk 91 is positioned, so that the first distance measuring instrument 322 can be used stably and the measurement accuracy is improved. After the measurement is completed, the rotating disk 91 is reversed, the connecting disk 32 can be lifted upward, and the connecting disk 32 can be taken out from the pile foundation, and then the rotating disk 91 is positioned again to complete the operation.

[0036] Specifically, the working process or working principle of a hoisting and positioning device for a pile foundation aperture measuring instrument is as follows: after the pile foundation is completed, the inner diameter needs to be measured. The current method of measuring the inner diameter of the pile foundation is mostly for the staff to hoist the measuring tool into the pile foundation, and after entering the pile foundation, unfold the measuring tool and press it against the inner wall of the pile foundation to measure the inner diameter. However, in actual use, when the measuring tool is hoisted into the pile foundation, it is easy to shake because it is suspended in the air. If the measuring tool shakes in the air, it will affect the measurement accuracy of the inner diameter of the pile foundation. Therefore, this device is designed to solve this problem.

[0037] Through this device, the connecting plate 32 can be hoisted into the interior of the pile foundation, and the electric telescopic rod 33 is used to push the plug rod 331 to move, so that the plug rod 331 is pressed against the inner wall of the pile foundation, thereby controlling the connecting plate 32 to be stably located inside the pile foundation. Then, the first distance measuring instrument 322 is controlled by remote control. When the two first distance measuring instruments 322 are working, the light beam is captured on the inner wall of the pile foundation. The measured distance is added to the distance between the two first distance measuring instruments 322 to obtain the diameter of the inside of the pile foundation.

[0038] In order to improve the measurement accuracy, in actual use, the position will be changed multiple times, and the measurement will be re-measured to take the average value. Under the premise of positioning the connecting disk 32, the measurement position of the first distance measuring instrument 322 can be changed by controlling the motor 6 to drive the circular plate 321 to rotate. By changing the measurement position multiple times and taking the average value, the inner diameter of the pile foundation can be obtained.

[0039] By controlling the rotation of the rotating disk 91, controlling the rotation of the round roller 2, and releasing the traction rope 31, the connecting disk 32 continues to fall into the pile foundation. According to actual measurement requirements, the connecting disk 32 is continuously moved downward, and the distance between the position of the connecting disk 32 and the second distance measuring instrument 8 is measured by the second distance measuring instrument 8. Therefore, the device can measure the inner diameter of the pile foundation while also measuring the depth of the pile foundation measurement position, thereby meeting the needs of use, obtaining more data, and facilitating subsequent construction.

[0040] After determining the position of the connecting disk 32, move the connecting plate 11, clamp the rubber rod 93 on the clamping plate 12 into the through hole 92 on the rotating disk 91, and position the rotating disk 91, so that the first distance measuring instrument 322 can be used stably and the measurement accuracy can be improved. After the measurement is completed, the rotating disk 91 is reversed, the connecting disk 32 can be lifted upward, and the connecting disk 32 can be taken out from the pile foundation. Then, the rotating disk 91 is positioned again to complete the operation.

[0041] It should be noted that the first distance measuring instrument 322, the electric telescopic rod 33, the control motor 6 and the second distance measuring instrument 8 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
