Description

Technical Field

[0001] The utility model relates to the field of civil engineering, in particular to a pile foundation depth measuring device. Background Art

[0002] Pile foundation is a commonly used foundation form in civil engineering, used to bear the load of buildings or other structures and transfer the load to deeper soil or rock layers. Pile foundation is usually a columnar structure made of materials such as concrete, reinforced concrete or steel. It is pre-buried or driven into the ground to increase the bearing capacity and stability of the foundation. The pile foundation depth measuring device is a device used to measure the depth of the pile foundation.

[0003] An existing pile foundation depth measuring device is usually equipped with a ruler, which is used to measure the depth. The depth of the pile foundation is then known by observing the scale. When the weather is gloomy and the light is dim, people need to remove the ruler to observe the scale, which can easily lead to errors in reading the scale and inaccurate depth measurement, thus affecting the measurement results.

[0004] Therefore, it is necessary to design a pile foundation depth measuring device that can measure the pile foundation depth by listening to the number of knocks, improve the measurement accuracy, reduce errors, and improve the measurement efficiency. Utility Model Content

[0009] Preferably, the prompt mechanism includes a rotating trigger wheel, a first fixed connecting frame, a sliding rod, a first spring, a second fixed connecting frame and a metal ball. The rotating trigger wheel is rotatably connected to the right front side of the lower part of the scale lamp tube, and the rotating trigger wheel is connected to the guide roller. The first fixed connecting frame is connected to the left front side of the lower part of the scale lamp tube.

The right part of the scale lamp tube is slidably connected to the sliding frame, the sliding frame is in contact with the coil, the front side of the sliding frame is slidably connected to the guide fixing frame, and the second spring is connected between the guide fixing frame and the sliding frame. By pulling the guide fixing frame to separate from the coil, the second spring is squeezed, and then the sliding frame is moved upward, and then the hand is released, the second spring rebounds, and the guide fixing frame is reset to clamp and fix the coil.

[0013] 2. The utility model moves the sliding frame upward, then lets go, the second spring rebounds, the guide fixing frame moves and resets to clamp and fix the coil, and then moves the sliding frame downward, thereby driving the coil to rotate downward to release the line, so that the pressure sensor moves downward into the pile foundation, thereby lowering the line to measure the depth of the pile foundation.

It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0022] A pile foundation depth measuring device, such as Figure 1-Figure 5 As shown, it includes a scale lamp tube 1, a support frame 2, a coil 3, a pressure sensor 5, a guide roller 6, a prompt mechanism 7 and a pulling mechanism 8. A handle is connected to the rear side of the middle part of the scale lamp tube 1, and the support frame 2 is connected to the left and right sides of the lower part of the scale lamp tube 1. The upper part of the scale lamp tube 1 is rotatably connected to the coil 3, and also includes a handle 4. The right side of the coil 3 is rotatably connected to the handle 4. The lower part of the coil 3 is connected to the pressure sensor 5, and the pressure sensor 5 is electrically connected to the scale lamp tube 1. The inner side of the lower part of the scale lamp tube 1 is rotatably connected to the left and right guide rollers 6, and the guide rollers 6 are in contact with the coil 3. The lower part of the scale lamp tube 1 is provided with a prompt mechanism 7 for prompting the measured value, and the scale lamp tube 1 is provided with a pulling mechanism 8 for pulling the coil 3.

[0023] like Figure 1-Figure 3As shown, the prompt mechanism 7 includes a rotating trigger wheel 70, a first fixed connecting frame 71, a sliding rod 72, a first spring 73, a second fixed connecting frame 74 and a metal ball 75. The rotating trigger wheel 70 is rotatably connected to the right front side of the lower part of the scale lamp tube 1, and the rotating trigger wheel 70 is connected to the guide roller 6. The first fixed connecting frame 71 is connected to the left front side of the lower part of the scale lamp tube 1. The sliding rod 72 is slidably connected to the first fixed connecting frame 71, and the sliding rod 72 is in contact with the rotating trigger wheel 70. A first spring 73 is connected between the sliding rod 72 and the first fixed connecting frame 71. The second fixed connecting frame 74 is connected to the left side of the lower part of the scale lamp tube 1. The second fixed connecting frame 74 is connected to the metal ball 75, and the metal ball 75 is in contact with the sliding rod 72.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the pulling mechanism 8 includes a sliding frame 80, a guide fixing frame 81, and a second spring 82. The sliding frame 80 is slidably connected to the right side of the calibrated lamp tube 1. The sliding frame 80 contacts the coil 3. The front side of the sliding frame 80 is slidably connected to the guide fixing frame 81. The front side of the guide fixing frame 81 is connected to a handle. A second spring 82 is connected between the guide fixing frame 81 and the sliding frame 80.

[0025] When it is necessary to measure the depth of the pile foundation, the device can be used. The device is picked up by the handle and placed on the pile foundation to be measured, so that the support frame 2 contacts the ground. The guide fixing frame 81 is pulled out of the coil 3 by the handle, and the second spring 82 is squeezed, thereby moving the sliding frame 80 upward, and then the hand is released, the second spring 82 rebounds, and the guide fixing frame 81 moves and resets to clamp and fix the coil 3, and then the sliding frame 80 is moved downward, thereby driving the coil 3 to rotate downward to release the line, so that the pressure sensor 5 moves downward into the pile foundation, thereby lowering the line to measure the depth of the pile foundation. The operation is simple and convenient for controlling the speed and length of the line release. When the pressure sensor 5 contacts the ground and is under pressure, the scale lamp 1 will flash a red light to remind people to pay attention, and then the coil 3 is no longer pulled downward. While the coil 3 moves downward, it will drive the guide roller 6 to rotate, thereby driving the rotating trigger wheel 70 to rotate and contact the sliding rod 72, thereby squeezing the sliding rod 72. Move leftward to knock the metal ball 75 on the second fixed connecting frame 74, the first spring 73 is squeezed, the rotating trigger wheel 70 rotates one circle, the sliding rod 72 knocks the metal ball 75 once, and the rotating trigger wheel 70 rotates one circle, and the length of the coil 3 falling is the same, so the pile foundation depth can be determined by listening to the number of knocks, and then the pile foundation depth can be measured, thereby improving the measurement accuracy, reducing errors, and improving the measurement efficiency. When the rotating trigger wheel 70 is disengaged from the sliding rod 72, the first spring 73 rebounds, and the sliding rod 72 moves and resets. At the same time, the position of the sliding frame 80 on the scale lamp tube 1 can be observed, and then the scale on the scale lamp tube 1 can be observed to read the value. When the pile foundation depth is deep, the sliding rod 72 can be repeatedly moved upward, and then the coil 3 can be pulled down for measurement, which is convenient for adapting to pile foundations of different depths and improving the usability of the device. After the measurement is completed, the coil 3 can be driven to rotate by pulling the handle 4, and then the line can be reeled in.
