Description

Technical Field

[0001] The invention relates to an adaptive terrain pile driving positioning device, belonging to the technical field of pile driving. Background Art

[0002] In construction projects, some piles are driven by bored piles. This method is mainly suitable for pile foundation construction that needs to be deep into the soil layer. The construction steps of bored piles are usually as follows: 1. Drilling: Use large machinery to drill the pile holes. Before construction, the soil at the drilling location needs to be cleaned and then drilled. The depth and diameter of the drill hole are usually determined according to the design requirements. Cleaning the hole: After drilling, the hole should be cleaned to ensure that there is no debris and mud residue in the hole, so as to prepare for the subsequent pouring construction. Put in the pipe pile: After the hole is cleaned, the prefabricated pipe pile (concrete pile) is placed in the hole. Pouring construction: After the pipe pile is placed in the hole, pouring construction is carried out. Usually, while ensuring verticality, concrete and other materials are poured into the hole through a conduit or other means until the pipe pile is completely fixed.

[0003] The verticality of pipe piles is one of the key factors affecting the stability of building structures. The verticality deviation between the pile body and the ground shall not exceed 0.5%~1%. If the verticality exceeds the prescribed range, it will have an adverse effect on subsequent construction and project quality.

[0004] The inventors have discovered that the prior art has at least the following technical problems:

[0005] At present, part of the construction is to form a natural verticality through hoisting, and then carry out pouring construction. If the hoisting method is adopted, it is necessary to adjust the pipe piles in the hoisting process in advance to ensure the verticality, which usually requires manual adjustment. Therefore, pile clamping equipment was developed later. The pile piles in the hoisting are clamped by the pile clamping equipment. After clamping, the oil cylinder at the lower end of the pile clamping equipment is used to make an overall adjustment, so that the pile clamping equipment is level as a whole. The clamped pipe piles are perpendicular to the pile clamping equipment, meeting the verticality requirement. However, the oil itself is easily affected by the ambient temperature factors, resulting in poor stability during precise adjustment and errors after adjustment. The oil cylinder is prone to oil leakage during use, and the hydraulic oil needs to be replaced regularly, resulting in high maintenance costs in the later stage. Summary of the invention

[0065] The level detection unit 2 is arranged and installed in a region between the upper clamping unit 1 and the lower clamping unit 3 .

[0066] A spring member 23 is connected between the support frame 42 and the detection frame 21 , and an adjustment mechanism 24 is connected to one end of the spring member 23 located on the detection frame 21 .

An inner slider 241 is installed on the inner side of the adjusting plate 242, and one end of the spring member 23 is installed on the inner slider 241.

[0068] Working process:

[0069] Step 1, the pushing component 43 is pre-activated to align the lower clamping unit 3 and the upper clamping unit 1 coaxially. When the pipe pile is hoisted and placed into the clamping area in the middle of the device, the upper clamping component 12, the lower clamping component 32 and the locking component 22 are activated, and the pipe pile is clamped and fixed.

[0070] In step two, after the pipe pile is clamped, it is subjected to the clamping force, and the pipe pile will be coaxial with the vertical clamping area of ​​the device. After being fully clamped, the device and the equipment driving the device are stable. At this time, through the clamping of the locking component 22, the inclination angle can be measured by the horizontal detection component 25 on the detection frame 21, and the distance and inclination angle between the upper clamping component 12 and the lower clamping component 32 can be used to obtain the length L of the lower clamping component 32 that needs to move based on the trigonometric function.

[0071] Step three, such as Figure 1 or Figure 5 As shown, three groups of electric cylinders 432 of the pushing component 43 retract, and another group of electric cylinders 432 moves forward a distance length L, that is, the distance length L obtained from step 2. At this time, the guide wheel 431 pushes the guide ring 433 to move, thereby moving the lower clamping unit 3. At this time, the other three groups of electric cylinders 432 are in action to fix the guide ring 433 to prevent it from moving around and causing deviation.

[0072] Step 4, the driving mechanism 44 drives the rotating disk 41 to rotate, and the rotating disk 41 drives the pushing component 43 to rotate. As the rotation occurs, the electric cylinder 432 in the pushing component 43 moves a distance L and pushes the lower clamping unit 3 to move. As the movement occurs, the detection frame 21 in the middle is rigidly clamped with the pipe pile, so the detection frame 21 moves with the pipe pile, and the axis of the pipe pile is always perpendicular to the horizontal plane of the detection frame 21. Specifically, the spring deformation in the spring member 23 ensures that the detection frame 21 follows the movement of the pipe pile. As the pipe pile changes, the inclination angle of the horizontal detection component 25 installed on the detection frame 21 changes from small to large, then decreases and gradually becomes zero, or the inclination angle directly changes from large to small, and gradually becomes zero. At this time, the verticality of the pipe pile is qualified and concrete can be poured into it for fixation.

[0073] Working principle:

[0074] like Fig. 9 As shown, the clamping column 123 is connected to the clamping plate 124 through a ball hinge. When the upper clamping unit 1 clamps the pipe pile, the pipe pile can be adjusted through the ball hinge. When the lower clamping unit 3 clamps, the pipe pile is locked and can no longer be adjusted. It can only be adjusted by the overall translation ball hinge of the lower clamping unit 3, thereby completing both the locking and adjustment of the pipe pile.
