[0002] To ensure the quality and safety of pile foundation engineering, verify the accuracy of design parameters, control construction costs and meet acceptance specifications, and avoid the risk of structural settlement due to insufficient pile length, it is necessary to measure the depth of cast-in-place pile foundations.
[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN220322263U discloses a pile hole depth measuring instrument for cast-in-place piles. During measurement, the staff can obtain the depth of the pile hole by observing how many times the second pulley rotates and calculating the scale line on it.

[0013] (1) The automatic pile foundation hole detection device in this utility model can automatically detect the depth of cast-in-place pile foundation, saving manual labor and reducing the impact of human factors on detection accuracy.
[0014] (2) Before measuring the depth, the bottom of the hammer is aligned with the ground by winding or releasing the hoisting rope. Then the hoisting rope is released. Under the action of the weight of the hammer, the hammer drives the hoisting rope to move down. The hoisting rope drives the friction wheel to rotate.

[0021] like Figures 1 to 4As shown, an automatic detection device for pile foundation drilling is disclosed, including a support 1. The support 1 has a vertical plate 12, and a horizontal plate 13 is vertically fixed at the top of the vertical plate 12. An elastic support mechanism 7 is provided on the horizontal plate 13, and a support plate 2 is suspended below the elastic support mechanism 7. A proximity switch 86 corresponding to the support plate 2 is provided on the horizontal plate 13. A friction wheel 3 is rotatably provided on one side of the support plate 2, and an encoder 9 that is drively connected to the friction wheel 3 is provided on the other side of the support plate 2. A [missing information - likely a device name] is provided on one side of the vertical plate 12. A rope winding mechanism 6 is provided, which includes a winding roller 62 rotatably mounted on one side of the upright plate 12 and a winding motor 63 that drives the winding roller 62 to rotate. A rope 64 is wound around the winding roller 62 and is fitted around the outside of the friction wheel 3. A counterweight 5 is fixedly mounted on the end of the rope 64 away from the winding roller 62. A display and control component 8 is fixedly mounted on the bracket 1. In this embodiment, the winding motor 63 in the rope winding mechanism 6 drives the winding roller 62 to rotate, thereby controlling the rotation of the winding roller 62. The side-wound suspension rope 64 is wound up or released. Before measuring the depth, the bottom of the hammer is aligned with the ground by winding or releasing the suspension rope. Then, the suspension rope 64 is released. Under the gravity of the hammer 5, the hammer 5 drives the suspension rope 64 to move downward. The suspension rope 64 drives the friction wheel 3 to rotate. The encoder 9 converts the rotation angle of the friction wheel 3 into a pulse signal and counts the pulse signal. After the hammer 5 touches the bottom, the suspension rope 64 loosens on the outside of the friction wheel 3, the elastic support mechanism 7 resets, and drives the support plate 2 to move upward, triggering the proximity switch 86. After the proximity switch 86 is triggered, the pulse counting stops. The display and control component 8 can obtain the depth of the cast-in-place pile according to the formula: Depth of cast-in-place pile foundation = (Total number of pulses ÷ Number of pulses per revolution) × circumference of friction wheel. The display and control component 8 is used to display the depth value of the cast-in-place pile foundation. The automatic pile foundation drilling detection device in this embodiment can automatically detect the depth of the cast-in-place pile foundation without manual calculation, saving manual effort and reducing the impact of human factors on the detection accuracy.
[0022] In some embodiments, the elastic support mechanism 7 has two guide rods 71 symmetrically arranged on the upper end of the support plate 2. The guide rods 71 are slidably connected to the horizontal plate 13. A top plate 72 is fixedly arranged at the top of the guide rods 71. A spring 73 is sleeved on the outside of the guide rods 71 between the top plate 72 and the horizontal plate 13. Under the gravity of the weight 5, the spring 73 is compressed, the support plate 2 moves away from the proximity switch 86, and the proximity switch 86 is not triggered. When the weight 5 touches the bottom, the suspension rope 64 loosens on the outside of the friction wheel 3, the spring 73 resets, the support plate 2 moves upward, and the proximity switch 86 is triggered.
[0023] In some embodiments, two clamping rollers 4 are symmetrically rotated on the support plate 2. The clamping rollers 4 are used to press the suspension rope 64 against the friction roller 3. By pressing the suspension rope 64 against the friction roller 3, the contact area between the suspension rope 64 and the friction roller 3 is increased, and the friction between the suspension rope 64 and the friction roller 3 is increased, so as to avoid slippage between the friction roller 3 and the suspension rope 64 and affect the detection accuracy.
[0024] In some embodiments, the display and control component 8 has a microcontroller 81, on which an up button 84, a down button 85, a display screen 82 and a motor driver 83 are connected. The motor driver 83 is connected to the winding motor 63, and the encoder 9 and the proximity switch 86 are connected to the microcontroller 81.
[0025] Specifically, the microcontroller 81 is an AT89C52 microcontroller. The up button 84 and down button 85 are connected to the P1.0 and P1.1 pins of the microcontroller, respectively. The display screen 82 is an LM016L LCD module, and the display screen 82 is connected to the P0.0 to P0.7 pins of the microcontroller. The motor driver 83 is connected to the microcontroller 81. In the initial state, the bottom of the counterweight 5 is flush with the bottom of the bracket 1. Pressing the down button 85 causes the microcontroller 81 to control the winding motor 63 to reverse, releasing the lifting rope 64. The lifting rope 64 drives the friction wheel 3 to rotate, the encoder 9 outputs a pulse signal, the microcontroller counts the encoder 9, the proximity switch 86 is triggered and stops counting, the microcontroller 81 outputs the pile foundation depth value of the grouting pile to the display screen 82 according to the preset algorithm; then press the rise button 84, the microcontroller 81 controls the winding motor 63 to rotate forward, wind up the lifting rope 64 and lift the weight 5, but when the weight 5 rises to be level with the bottom of the support 1, press the rise button 84 again to stop the winding motor 83.
[0026] In some embodiments, the take-up roller 62 is rotatably provided with bearing seats 61 at both ends, and the bearing seats 61 are fixedly provided on one side of the upright plate 12; the take-up roller 62 is rotatably mounted on one side of the upright plate 12 through the bearing seats 61, and the take-up motor 63 is mounted on the outside of the bearing seats 61, and the output shaft of the take-up motor 63 drives the take-up roller 62.
[0027] In some embodiments, a base plate 11 is vertically fixed to the bottom end of the upright plate 12; specifically, the upright plate 12 is vertically welded to the top of the base plate 11, and when taking measurements, the measuring personnel can step on the base plate 11 to keep the support 1 stable.
