DETAILED DESCRIPTION
[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figures 1 to 4As shown, a prefabricated pipe pile coring detection device includes a lifting mechanism, a positioning mechanism and a drilling coring mechanism, wherein the positioning mechanism is arranged at the bottom of the lifting mechanism and is used for positioning; the drilling coring mechanism includes a mounting frame 1, a power device 11, a drill bit 2 and a protective cover 3; one side of the mounting frame 1 is fixedly connected to the lifting mechanism; through the lifting mechanism, the drilling coring mechanism can be conveniently controlled to reach a specified position, which greatly improves the work efficiency and the flexibility of operation. The power device 11 is arranged on the mounting frame 1, and the output end of the power device 11 is connected to the rotating shaft 12; the rotating shaft 12 is connected to the drill bit 2; a shock absorbing frame 4 is arranged at the bottom of the mounting frame 1; the rotating shaft 12 passes through the bottom of the shock absorbing frame 4 and is connected to the drill bit 2; the protective cover 3 is arranged below the shock absorbing frame 4; the drill bit 2 is located inside the protective cover 3; the setting of the protective cover can protect the operator during the operation and prevent the safety risks caused by splashing or fragments of the drill bit 2. At the same time, it can also reduce the influence of external factors on the operation of the drill bit 2 and improve the operation quality. A support 31 is provided on the outer peripheral wall of the protective cover 3; a guide rod 32 is fixedly provided on the support 31, and the other end of the guide rod 32 passes through the shock absorbing frame 4 and the mounting frame 1 and is fixed to the top of the mounting frame 1 by bolts; a shock absorbing spring 41 is provided between the protective cover 3 and the shock absorbing frame 4.
[0022] The combination of the shock-absorbing frame 4 and the shock-absorbing spring 41 can effectively reduce the vibration generated by the drill bit 2 during operation, which not only protects the equipment itself and prolongs its service life, but also improves the operation accuracy and reduces the error caused by vibration. The setting of the guide rod 32 and the support 31 further enhances the connection stability between the protective cover 3 and the mounting frame 1, prevents displacement or shaking during operation, and improves the stability of the overall structure.
[0023] like Figure 1 and Figure 2 As shown, the lifting mechanism includes a lifting frame 5, a power mechanism 51 and a connecting block 52; the power mechanism 51 is arranged on the top of the lifting frame 5, and the output end of the power mechanism 51 passes through the top of the lifting frame 5 and is fixedly connected to the connecting block 52; guide columns 53 are arranged on both sides of the middle of the lifting frame 5, and both sides of the connecting block 52 are slidably arranged on the guide columns 53; the side walls of the connecting block 52 are fixedly connected to the mounting frame 1.
[0024] By setting a lifting mechanism to control the position height of the drilling coring mechanism, during the coring detection process of the prefabricated pipe piles, coring samples at different depths can be detected, thereby improving the detection accuracy.
[0025] like Figure 1 and Figure 4As shown, the positioning mechanism includes a positioning base 6, a clamping plate 7 and an adjusting bolt 71; the positioning base 6 is fixedly arranged below the lifting frame 5; an adjusting slot 61 is opened on the positioning base 6; the clamping plate 7 is slidably arranged in the adjusting slot 61 and is located below the positioning base 6; two clamping plates 7 are arranged in the adjusting slot 61; the adjusting bolt 71 is connected to the top of the two clamping plates 7.
[0026] By setting the positioning mechanism, the lifting mechanism can be stably installed on the prefabricated pipe pile, and the distance between the clamping plates 7 can be conveniently adjusted by adjusting the bolts 71, thereby achieving clamping of prefabricated pipe piles of different sizes, with a wider range of applications and improved work efficiency.
[0027] like Figure 2 As shown, a bearing seat 8 is provided on the shock absorbing frame 4 , and the bearing seat 8 is arranged at a position where the rotating shaft 12 and the shock absorbing frame 4 penetrate.
[0028] By setting the bearing seat 8, the direct contact area between the rotating shaft 12 and the shock-absorbing frame 4 can be reduced, thereby reducing friction and wear. At the same time, when the drill bit 2 is working, the vibration energy can be well transmitted to the shock-absorbing seat, and the shock-absorbing seat then alleviates the vibration energy through the shock-absorbing spring 41, thereby improving the integrity of the coring.
[0029] like Figure 2 and Figure 3 As shown, an annular receiving groove 33 is formed at the bottom of the protection cover 3 , and a water flow hole 34 is formed on the side wall of the annular receiving groove 33 .
[0030] By providing the water flow hole 34, the drill bit 2 can be effectively cooled and its temperature can be reduced during operation, thereby improving the durability and service life of the drill bit 2. At the same time, the water flowing out of the water flow hole 34 can wash away the waste chips and dust attached to the drill bit 2, keeping the drill bit 2 clean, thereby improving the quality and efficiency of drilling.
[0031] Working principle of the utility model: First, the lifting mechanism is positioned by the positioning mechanism. The whole device is placed above the prefabricated pipe pile, wherein the clamping plate 7 is located on both sides of the prefabricated pipe pile. The distance between the two clamping plates 7 can be adjusted by adjusting the bolts 71, so that the clamping plates 7 on both sides are fixed on both sides of the prefabricated pipe pile, ensuring that the lifting mechanism remains stable during the coring process. Next, the lifting mechanism is adjusted to a suitable height according to the coring depth requirement. The power mechanism 51 drives the connecting block 52 to slide on the guide column 53 of the lifting frame 5, thereby driving the mounting frame 1 fixedly connected to the connecting block 52 to rise and fall. The power mechanism 51 is preferably a telescopic motor. Then, the drilling and coring mechanism starts to work. The power device 11 on the mounting frame 1 is started, wherein the power device 11 is preferably a rotating motor, and the output end of the rotating motor is connected to the rotating shaft 12, thereby driving the rotating shaft 12 and the drill bit 2 connected to the rotating shaft 12 to rotate. While the drill bit 2 rotates at high speed, it gradually penetrates into the interior of the prefabricated pipe pile through the lifting action of the lifting mechanism to perform coring. During the coring process, the protective cover 3 is located below the shock-absorbing frame 4, covering the drill bit 2 therein to prevent splashes generated by the drill bit 2 during operation from affecting the surrounding environment. At the same time, the shock-absorbing spring 41 arranged between the protective cover 3 and the shock-absorbing frame 4 can absorb the vibration of the drill bit 2 during operation, reducing the impact of vibration on the entire equipment and the operator. At the same time, when the drill bit 2 is working, water is continuously injected from the water flow hole 34, which can effectively cool the drill bit 2 on the one hand, and on the other hand, it can wash away the waste and dust attached to the drill bit 2, keep the drill bit 2 clean, and thus improve the quality and efficiency of drilling.
[0032] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
