Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pile drivers, and in particular relates to a pile driving initial position identifiable mechanism of a static pile driver. Background Art
[0002] A static pile driver is a type of construction equipment used in the construction of bridges, ports, roads, and other projects. It is mainly used for compacting soil and concrete piles. This type of equipment is highly efficient and fast, and can complete pile construction tasks in a relatively short period of time, significantly improving construction efficiency. During the static pile construction process, since the pile driving depth will affect the bearing capacity and stability of the static pile, it is also an important parameter for judging whether the foundation pile meets the project quality requirements. Therefore, timely records are required during construction. The calculation of the pile driving depth requires first knowing the starting point of the pile material. Currently, the definition of the starting point of the pile material in the industry is usually determined by construction personnel visually confirming and recording the pile material placed on the ground. However, such record judgments rely heavily on the experience and proficiency of the construction personnel. At the same time, their effectiveness, reliability, and timeliness are difficult to guarantee, and may even leave room for cutting corners. Utility Model Content

[0012] The specific embodiment of the utility model will be further described in detail below by combining with the drawings, so that the technical scheme of the utility model is easier to understand and master. DRAWINGS
[0013] In order to more clearly illustrate the technical scheme of the utility model embodiment, the drawings needed in the embodiment description will be briefly introduced, and obviously, the drawings in the following description are some embodiments of the utility model, and for those skilled in the art, other drawings can also be obtained without creative labor.
[0014] Figure 1 It is the structural schematic diagram of the utility model.
[0015] Figure 2 It is the structural schematic diagram when the utility model measures the initial position of pile material. SPECIFIC EMBODIMENT
[0016] The utility model discloses a kind of initial position of pile of static force pile driver can be identified mechanism, combined with Figure 1 As shown in the drawing, the identifiable mechanism is usually used with static force pile driver, and the static force pile driver is the same as the existing static force pile driver main body structure, and both include pile machine platform 1 erected on leveling mechanism 11, and the pile machine platform 1 is provided with pile pressing mechanism 2.
[0017] The identifiable mechanism is placed at the bottom of the pile machine platform 1, and is used for assisting to measure the initial position of pile material, and it includes at least one group of distance measuring sensing assembly 3, and the distance measuring sensing assembly 3 includes laser ranging sensor.
[0018] The distance measuring sensing assembly 3 is connected with the control analysis unit, the distance measuring sensing assembly 3 includes a first laser distance measuring sensor 31 and a second laser distance measuring sensor 32 arranged outside the first laser distance measuring sensor, and an included angle is arranged between the first laser distance measuring sensor 31 and the second laser distance measuring sensor 32. Specifically, the laser sensing end of the first laser distance measuring sensor 31 is inclined to the direction of the pile material 5, that is, the first laser distance measuring sensor 31 is used to measure the straight line distance when intersecting with the bottom of the pile material 5. The laser sensing end of the second laser distance measuring sensor 32 is arranged vertically downward, which is used to measure the vertical distance between the second laser distance measuring sensor 32 and the ground 4. In order to better monitor, the transverse distance between the distance measuring sensing assembly 3 and the pile material 5 is 0.8-1.5 meters.
[0019] Because in the actual operation, the ground 4 will be uneven, if still through the construction personnel directly placed on the ground as the starting position, thereby calculating and judging the subsequent pile pressing depth, it is inevitable that the calculation result is inaccurate, and the present application can avoid this situation. At the same time, in order to make the monitoring data more accurate, the distance measuring sensing assembly 3 is provided with two groups, which are symmetrically arranged on both sides of the pile pressing mechanism, and the data obtained from both sides are compared to verify the accuracy of the data. Of course, the two distance measuring sensing assemblies 3 can also not be symmetrically arranged, but the principle of monitoring and identifying the starting position of the pile material is the same, and the data collection and verification of both sides can also be realized.
[0020] In order to better understand the data measurement of the starting position of the pile material by the pile pressing machine through the present application, the principle of measurement by the distance measuring sensing assembly on one side is described as follows:
[0021] Firstly, the present application needs to obtain the starting position of the pile material 5, and in combination with Figure 2 , the starting position is defined as the vertical distance between the bottom of the pile and the ground 4 when the laser sensing line of the first laser distance measuring sensor 31 intersects and contacts with the bottom of the pile when the pile material 5 is lowered.
[0022] When the pile material 5 is lowered, the transverse distance between the first laser distance measuring sensor 31 and the pile material 5 is d0, the straight line distance between the laser sensing line of the first laser distance measuring sensor and the bottom of the pile is L, the vertical distance between the first laser distance measuring sensor and the pile material 5 is h2, the vertical distance between the second laser distance measuring sensor 32 and the ground 4 is h3, and the vertical distance difference between the first laser distance measuring sensor 31 and the second laser distance measuring sensor 32 is Δh, then the distance between the initial position of the pile material and the ground is h1. Therefore, the value of h1 can be obtained to obtain the initial position of the pile material.
[0023] The distance between the initial position of the pile and the ground is h1=h3- Ah-h2. Based on the above principle, the distance between the distance measuring induction assembly 3 and the pile is usually set to 0.8-1.5 meters, because if the distance between the distance measuring induction assembly and the pile is too close, the first laser distance measuring sensor 31 will intersect with the pile too early, and the system will identify the initial position too early, which may cause misjudgment. If the distance is too far, the laser of the first laser distance measuring sensor 31 may directly irradiate the ground, and cannot form an intersection with the pile, causing a judgment error.
[0024] The distance measuring induction assembly 3 in the mechanism will acquire the initial modeling data when the first laser distance measuring sensor intersects with the pile during the installation and debugging stage, which is used as a reference standard. When actually used, during the pile driving process, when the straight-line distance between the first laser distance measuring sensor 31 and the pile is much smaller than the initial data, the system judges that the starting point has not been reached. As the pile descends, the straight-line distance between the first laser distance measuring sensor 31 and the pile will approach the initial data infinitely, until the system judges that the starting point is reached when the intersection occurs. At this moment, the vertical distance h3 is acquired by the second laser distance measuring sensor 32, and finally h1 is calculated.
