TECHNICAL FIELD
[0001] The present application relates to the technical field of pile foundation construction, and in particular to a wind turbine generator foundation PHC pipe pile rapid construction auxiliary equipment. BACKGROUND
[0002] The PHC pipe pile of the wind turbine generator foundation needs to be driven into the ground by a pile driver for pile sinking during construction. The pipe pile is prone to deflection during pile sinking, and thus the verticality of the pipe pile during pile sinking needs to be detected to assist the pipe pile in pile sinking, so as to avoid the situation of pile body deflection.
[0003] At present, the verticality detection of the pipe pile mainly relies on the plumb bob method, that is, the plumb bob is connected to the pipe pile, and the verticality of the plumb bob in the front and side directions is observed to determine whether the pipe pile is deflected during pile sinking. Although the plumb bob method is simple to operate, the detection accuracy is low, and it is difficult to accurately detect the verticality of the pipe pile. CONTENT OF THE UTILITY MODEL
[0004] In order to accurately detect the verticality of the pipe pile during pile sinking, the present application provides a wind turbine generator foundation PHC pipe pile rapid construction auxiliary equipment.
[0005] The wind turbine generator foundation PHC pipe pile rapid construction auxiliary equipment provided by the present application adopts the following technical scheme:
[0006] The wind turbine generator foundation PHC pipe pile rapid construction auxiliary equipment comprises a support seat and a detection assembly. The support seat is annular and is installed on the ground. The support seat is used for sleeving the pipe pile. A plurality of detection holes are formed in the support seat in the circumferential direction. The detection assembly is provided in multiple groups and corresponds to the detection holes one by one. The detection assembly comprises a detection telescopic rod, an air pressure sensor and a display. The detection telescopic rod is arranged in the detection hole. The rod cavity of the detection telescopic rod is in communication with the atmosphere. The rodless cavity of the detection telescopic rod is sealed with air. The movable end of the detection telescopic rod abuts against the side wall of the pipe pile. The air pressure sensor is arranged in the rodless cavity of the detection telescopic rod and is used for outputting an air pressure signal. The display is connected to the detection telescopic rod and is electrically connected to the air pressure sensor. The display is used for displaying the air pressure signal in the form of numbers.
[0007] By adopting the technical scheme, in the pile sinking process of the pipe pile, the movable end of the detection telescopic rod abuts against the side wall of the pipe pile, the fixed end of the detection telescopic rod is fixed at a distance from the pipe pile under the support of the support seat, when the pipe pile is deflected, the movable end of the detection telescopic rod in the deflection direction of the pipe pile is subjected to the pushing force of the pipe pile, so that the movable end of the detection telescopic rod in the deflection direction of the pipe pile can be retracted, the movable end of the detection telescopic rod can increase the air pressure in the rodless cavity of the detection telescopic rod when retracted, so that the air pressure signal output by the air pressure sensor is increased, and the number displayed on the display is also increased, the deflection of the pipe pile can be accurately reflected through the position of the display on the pipe pile and the size of the number change on the display, so that the perpendicularity of the pipe pile in the pile sinking process can be accurately detected.
[0008] Optionally, the detection telescopic rod is arranged in the detection hole in a sliding manner along a direction close to or away from the pipe pile, a plurality of fixing assemblies are arranged on the support seat, the fixing assemblies correspond to the detection telescopic rods one by one, and the fixing assemblies are used for fixing the detection telescopic rods relative to the support seat.
[0009] By adopting the technical scheme, the detection telescopic rod is slid, the position of the detection telescopic rod relative to the pipe pile can be adjusted, and after the position of the detection telescopic rod is adjusted, the movable end of the detection telescopic rod can abut against the pipe pile with different diameters through the fixing effect of the fixing assembly, so that the auxiliary equipment can adapt to the pipe pile with different diameters.
[0010] Optionally, the movable end of the detection telescopic rod is pressed against the side wall of the pipe pile in an initial state.
[0011] By adopting the technical scheme, before the perpendicularity of the pipe pile is detected, the detection telescopic rod is slid, the movable end of the detection telescopic rod is pressed against the side wall of the pipe pile after retraction, the rodless cavity of the detection telescopic rod pre-exerts a pre-pressure on the air pressure sensor, and thus the pushing force exerted by the detection telescopic rod on the pipe pile can have a more sensitive response.
[0012] Optionally, the fixing assembly comprises a fixing rod, the fixing rod is slid through the support seat and into the detection hole, and the detection telescopic rod is provided with a plurality of fixing grooves in a sliding direction of the detection telescopic rod, and the end portion of the fixing rod is clamped in one of the fixing grooves.
[0013] By adopting the technical scheme, after the position of the detection telescopic rod is adjusted, the fixing rod is slid, the end portion of the fixing rod is clamped into the fixing groove on the detection telescopic rod, and the fixing rod can fix the detection telescopic rod under the limitation of the support seat, so that the detection telescopic rod is difficult to slide.
[0014] Optionally, the fixing assembly further includes a fixing frame and an anti-detachment plate. The fixing frame is connected to the support base, the fixing rod is located inside the fixing frame and is slidably connected to the fixing frame, and the anti-detachment plate is slidably inserted through the fixing frame. When the end of the fixing rod is engaged in the fixing groove, the end of the fixing rod away from the fixing groove abuts against the anti-detachment plate. The anti-detachment plate is used to prevent the end of the fixing rod from detaching from the fixing groove.
[0015] By adopting the above technical solution, the sliding of the fixing rod is restricted by the anti-detachment plate, making it difficult for the end of the fixing rod to slip out of the fixing groove, thereby making the fixing rod stable and reliable in fixing the detection telescopic rod.
[0016] Optionally, it also includes a correction component, which includes a support frame and correction cylinders. The support frame is ring-shaped and installed on the ground. The support frame is sleeved on the pipe pile. Multiple correction cylinders are provided, each corresponding to a detection telescopic rod. The correction cylinders are connected to the support frame, and the movable end of the correction cylinder abuts against the side wall of the pipe pile.
[0017] By adopting the above technical solution, when the pipe pile is deviated, the detection telescopic rod in the direction of deviation can detect the deviation of the pipe pile. By detecting the change of the number displayed on the monitor corresponding to the detection telescopic rod, the correction cylinder corresponding to the detection telescopic rod is activated. Under the support of the support frame, the correction cylinder can drive the pipe pile to swing to a vertical state.
[0018] Optionally, both the movable end of the correction cylinder and the movable end of the detection telescopic rod are rotatably connected to rollers.
[0019] By adopting the above technical solution, the rolling action between the roller and the pipe pile makes the moving end of the correction cylinder and the moving end of the detection telescopic rod less prone to wear.
[0020] Optionally, both the support base and the support frame are connected to fixing nails, which are used to insert into the formation.
[0021] By adopting the above technical solution, the fixing nails fix the support base and support frame to the ground, making it difficult for them to move relative to the ground, thus ensuring that the support base and support frame can be stably installed on the ground.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a support base, detecting the telescopic rod, air pressure sensor and display, the verticality of the pipe pile can be detected digitally, thereby accurately detecting the verticality of the pipe pile during the pile driving process;
[0024] 2. By setting a fixed rod, a fixed frame, and an anti-detachment plate, the position of the telescopic detection rod can be quickly fixed after adjustment;
[0025] 3. By setting up a support frame and a correction cylinder, the pipe pile can be corrected after it deviates. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.
[0031] This application discloses an auxiliary device for rapid construction of PHC pipe piles for wind turbine foundations. (Refer to...) Figure 1 and Figure 2 A rapid construction auxiliary device for PHC pipe piles for wind turbine generator foundations includes a support base 1 and a detection component 2. The support base 1 is ring-shaped and installed on the ground. The support base 1 is used to fit onto the pipe pile. Multiple detection holes 11 are opened along the circumference of the support base 1. Multiple sets of detection components 2 are provided, and each detection hole 11 corresponds to one of the detection holes 11. The detection component 2 includes a detection telescopic rod 21, a pressure sensor 22, and a display 23.
[0032] Reference Figure 2 The detection telescopic rod 21 is installed inside the detection hole 11. The rod-side cavity of the detection telescopic rod 21 is open to the atmosphere, while the rodless cavity is sealed with air. The movable end of the detection telescopic rod 21 abuts against the side wall of the pipe pile. The air pressure sensor 22 is fixedly installed in the rodless cavity of the detection telescopic rod 21 and is used to output air pressure signals. The display 23 is fixedly connected to the detection telescopic rod 21 and electrically connected to the air pressure sensor 22. The display 23 is used to display the air pressure signals in digital form.
[0033] During use, in the process of driving the pipe pile, the movable end of the detection telescopic rod 21 abuts against the side wall of the pipe pile. Under the support of the support seat 1, the fixed end of the detection telescopic rod 21 is kept at a fixed distance from the pipe pile. When the pipe pile deviates, the movable end of the detection telescopic rod 21 in the direction of deviation will be pushed by the pipe pile, causing the movable end of the detection telescopic rod 21 in the direction of deviation to retract. When the movable end of the detection telescopic rod 21 retracts, it can increase the air pressure in its rodless cavity, thereby increasing the air pressure signal output by the air pressure sensor 22. At the same time, the number displayed on the display 23 will also increase. By observing the position of the pipe pile where the display 23 is located and the magnitude of the change in the number on the display 23, the deviation of the pipe pile can be accurately reflected, thereby accurately detecting the verticality of the pipe pile during the driving process.
[0034] Reference Figure 2 In order to enable the auxiliary equipment to adapt to pipe piles of different diameters, the detection telescopic rod 21 is slidably installed in the detection hole 11 in the direction of approaching or moving away from the pipe pile. Multiple sets of fixing components 3 are provided on the support base 1. The fixing components 3 correspond one-to-one with the detection telescopic rod 21. The fixing components 3 are used to fix the detection telescopic rod 21 relative to the support base 1.
[0035] The sliding telescopic rod 21 can adjust the position of the telescopic rod 21 relative to the pipe pile. After adjusting the position of the telescopic rod 21, the movable end of the telescopic rod 21 can abut against pipe piles of different diameters through the fixing action of the fixing component 3, so that the auxiliary equipment can adapt to pipe piles of different diameters.
[0036] Furthermore, referring to Figure 1 The test shows that the movable end of the telescopic rod 21 is pressed against the side wall of the pipe pile in the initial state.
[0037] Before testing the verticality of the pipe pile, the detection telescopic rod 21 is slid down so that the movable end of the detection telescopic rod 21 presses against the side wall of the pipe pile after it is retracted. This allows the rodless cavity of the detection telescopic rod 21 to apply pre-pressure to the air pressure sensor 22, thereby enabling the detection telescopic rod 21 to have a more sensitive response to the thrust applied to the pipe pile.
[0038] Specifically, refer to Figure 2 The fixing component 3 includes a fixing rod 31, which slides through the support base 1 and enters the detection hole 11. The detection telescopic rod 21 has multiple fixing grooves 211 along its sliding direction, and the end of the fixing rod 31 is engaged in one of the fixing grooves 211.
[0039] After adjusting the position of the detection telescopic rod 21, slide the fixing rod 31 so that the end of the fixing rod 31 is engaged in the fixing groove 211 on the detection telescopic rod 21. Under the restriction of the support seat 1, the fixing rod 31 can fix the detection telescopic rod 21, making it difficult for the detection telescopic rod 21 to slide.
[0040] Furthermore, referring to Figure 2 The fixing component 3 also includes a fixing frame 32 and an anti-detachment plate 33. The fixing frame 32 is fixedly connected to the support base 1. The fixing rod 31 is located inside the fixing frame 32 and is slidably connected to the fixing frame 32. The sliding direction of the fixing rod 31 is perpendicular to the sliding direction of the detection telescopic rod 21. The anti-detachment plate 33 is slidably installed on the fixing frame 32. The sliding direction of the anti-detachment plate 33 is perpendicular to the sliding direction of the fixing rod 31. When the end of the fixing rod 31 is engaged in the fixing groove 211, the end of the fixing rod 31 away from the fixing groove 211 abuts against the anti-detachment plate 33. The anti-detachment plate 33 is used to prevent the end of the fixing rod 31 from detaching from the fixing groove 211.
[0041] The anti-slip plate 33 restricts the sliding of the fixing rod 31, making it difficult for the end of the fixing rod 31 to slip out of the fixing groove 211, thereby making the fixing rod 31 stable and reliable in fixing the detection telescopic rod 21.
[0042] Reference Figure 1 In order to straighten the pipe pile into a vertical state after it is tilted, a rapid construction auxiliary device for PHC pipe piles of wind turbine generator foundations also includes a correction component 4. The correction component 4 includes a support frame 41 and a correction cylinder 42. The support frame 41 is ring-shaped and installed on the ground. The support frame 41 is sleeved on the pipe pile. Multiple correction cylinders 42 are provided and correspond one-to-one with the detection telescopic rod 21. The correction cylinder 42 is fixedly connected to the support frame 41, and the movable end of the correction cylinder 42 abuts against the side wall of the pipe pile.
[0043] When the pipe pile is deviated, the detection telescopic rod 21 in the deviated direction can detect the deviation of the pipe pile. By the change of the number displayed on the display 23 corresponding to the detection telescopic rod 21, the correction cylinder 42 corresponding to the detection telescopic rod 21 is activated. Under the support of the support frame 41, the correction cylinder 42 can drive the pipe pile to swing to a vertical state.
[0044] Furthermore, referring to Figure 1 and Figure 2 Both the movable end of the correction cylinder 42 and the movable end of the detection telescopic rod 21 are rotatably connected to rollers 421.
[0045] The rolling action between the roller 421 and the pipe pile makes it less prone to wear on the moving end of the correction cylinder 42 and the moving end of the detection telescopic rod 21.
[0046] Furthermore, referring to Figure 1Both the support base 1 and the support frame 41 are connected to fixing nails 12, which are used to be inserted into the formation.
[0047] The fixing nail 12 secures the support base 1 and the support frame 41 to the ground, making it difficult for them to move relative to the ground, thus ensuring that the support base 1 and the support frame 41 can be stably installed on the ground.
[0048] The implementation principle of the rapid construction auxiliary equipment for PHC pipe piles of wind turbine generator foundations in this application embodiment is as follows: When in use, the movable end of the detection telescopic rod 21 is pressed against the pipe pile. When the pipe pile is tilted, the detection telescopic rod 21 in the tilted direction can retract to increase the air pressure in its rodless cavity, so that the air pressure signal output by the air pressure sensor 22 can increase. According to the change of the numbers displayed on the display 23, the correction cylinder 42 corresponding to the detection telescopic rod 21 is activated. The correction cylinder 42 pushes the pipe pile to a vertical state, thereby accurately detecting the verticality of the pipe pile during the pile driving process.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
