Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station pile foundation construction, and in particular to a micro-hole grouting pile positioning device. Background Technology

[0002] As one of the most important renewable energy sources, photovoltaic power plants are being built in large numbers across the country in response to the national call. The photovoltaic support structure and foundation are the most important components in the construction of photovoltaic power plants.

[0003] New energy photovoltaic projects are characterized by tight schedules and wide work areas, which often leads to unsatisfactory construction accuracy of the photovoltaic support foundation. This results in phenomena such as offset and tilting of the photovoltaic support foundation piles. The flatness or tilt of the photovoltaic support installation site also affects the vertical installation of the photovoltaic support foundation piles. Deviations in the foundation piles will directly lead to large installation errors in the upper support, thereby increasing the construction and installation period and handling costs. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to improve the installation accuracy of photovoltaic support foundation piles.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A micro-hole cast-in-place pile positioning device includes a top plate, with a horizontal state detection mechanism at the upper end of the top plate; at least three telescopic outriggers are circumferentially and evenly spaced downwards on the top plate; a positioning column is vertically positioned at the lower end of the top plate, with the bottom end of the positioning column used to connect to the cast-in-place pile sleeve; an alignment detection mechanism is also provided at the bottom end of the positioning column for detecting whether it is aligned with the ground hole; and a control system is also included, which is electrically connected to the horizontal state detection mechanism, the telescopic outriggers, and the alignment detection mechanism.

[0006] Furthermore, the aforementioned positioning column includes a cylindrical segment and a conical segment connected sequentially from top to bottom. The conical segment is used to fit onto the aforementioned cast-in-place pile sleeve, and a fixing structure is provided between the conical segment and the aforementioned cast-in-place pile sleeve.

[0007] Furthermore, the aforementioned fixing structure includes a first pin hole perpendicularly inserted into the aforementioned conical section, and a second pin hole perpendicularly inserted into the aforementioned cast-in-place pile sleeve, and also includes a fixing pin inserted into both the aforementioned first pin hole and the aforementioned second pin hole.

[0008] Furthermore, the aforementioned alignment detection mechanism includes a shadow image sensor for acquiring vertically downward ground images.

[0009] Furthermore, the aforementioned leveling detection mechanism includes a level.

[0010] Furthermore, the aforementioned telescopic outriggers are configured as three, with the included angle between any two of the aforementioned telescopic outriggers being 120°.

[0011] The beneficial effects of this utility model are: With the automatic adjustment of the control system, the roof can move horizontally within a certain range by multiple adjustable telescopic outriggers. The positioning and detection mechanism on the positioning column detects the position of the ground holes, and the horizontal state detection mechanism monitors the horizontal state of the roof and feeds it back to the control system. The control system adjusts the telescopic outriggers to keep the roof horizontal, thereby ensuring the accuracy and stability of the installation of the cast-in-place piles and preventing the piles from shifting or tilting.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown in the figure, this application proposes a micro-hole cast-in-place pile positioning device, including a top plate 1, a horizontal state detection mechanism 2 is provided on the upper end of the top plate 1; at least three telescopic support legs 3 are provided on the top plate 1 at uniform intervals around the circumference and rotate downwards; a positioning column 4 is provided on the lower end of the top plate 1, and the bottom end of the positioning column 4 is used to connect the cast-in-place pile sleeve 5; the bottom end of the positioning column 4 is also provided with an alignment detection mechanism 7 for detecting whether it is aligned with the ground hole; and a control system is also included, which is electrically connected to the horizontal state detection mechanism 2, the telescopic support legs 3 and the alignment detection mechanism 7.

[0015] First, it should be stated that, through the automatic adjustment of multiple adjustable telescopic outriggers 3, the top plate 1 can be moved horizontally within a certain range. The positioning detection mechanism 7 on the positioning column 4 detects the position of the ground holes, and the horizontal state detection mechanism 2 monitors the horizontal state of the top plate 1 and feeds it back to the control system. At the same time, the control system adjusts the telescopic outriggers 3 to keep the top plate 1 horizontal, thereby ensuring the accuracy and stability of the installation of the cast-in-place piles.

[0016] The aforementioned telescopic outriggers 3 can be existing pneumatic or hydraulic telescopic structures, capable of automatic extension and retraction via a control system. By adjusting the preset extension and retraction amount of each telescopic outrigger 3, the top plate 1 is offset in a horizontal position, thereby adjusting the alignment position of the positioning column 4 with the ground hole. The specific control system includes an existing controller, which receives the detection signal from the alignment detection mechanism 7 to determine whether the alignment with the ground hole is achieved, thereby controlling each telescopic outrigger 3 to extend and retract, enabling the positioning column 4 to move within a horizontal range. Throughout the process, the horizontal state detection mechanism 2 sends a horizontal signal to the controller in real time, and the controller controls multiple telescopic outriggers 3 to extend and retract, leveling the top plate 1 while ensuring that the horizontal position of the top plate 1 does not move. When the alignment detection mechanism 7 detects the alignment with the ground hole, it controls multiple telescopic outriggers 3 to retract synchronously, allowing the cast-in-place pile sleeve 5 to accurately and stably enter the preset hole in the ground.

[0017] The alignment detection mechanism 7 is a shadow image sensor, and the horizontal state detection mechanism 2 is an existing electronic level. Specifically, the camera that collects shadow images is installed at the bottom center of the positioning column 4. When the shadow image sensor collects a circular image that is not a ground hole, it indicates that the micro-hole grouting pile sleeve 5 is not aligned with the ground hole to be inserted. At this time, the control system causes the telescopic support leg 3 to extend and retract adaptively according to the image signal collected by the shadow image sensor, maintaining the horizontal movement of the positioning device platform end plate, the positioning column 4 below it, and the micro-hole grouting pile sleeve 5. When the shadow image collected by the shadow image sensor is a circle of a preset size, it indicates that the micro-hole grouting pile sleeve 5 is aligned with the ground hole to be inserted. At this time, the control system causes the support leg to retract simultaneously according to the image signal collected by the shadow image, so that the positioning device platform end plate remains horizontal and the micro-hole grouting pile sleeve 5 moves vertically downward without horizontal deviation.

[0018] In this embodiment, the number of telescopic outriggers 3 is set to 3, and the included angle between any two of the above telescopic outriggers 3 is 120°. The 3 telescopic outriggers 3 form a stable triangular support system, which improves the support stability. Moreover, with fewer telescopic outriggers 3, the horizontal adjustment and leveling of the top plate 1 can be achieved with less adjustment and control.

[0019] The aforementioned positioning post 4 includes a cylindrical section 41 and a conical section 42 connected sequentially from top to bottom. The conical section 42 is used to fit into the aforementioned cast-in-place pile sleeve 5. A fixing structure is provided between the conical section 42 and the aforementioned cast-in-place pile sleeve 5. The setting of the conical section 42 facilitates the stable insertion of the bottom end of the positioning post 4 into the inner hole of the cast-in-place pile sleeve 5, achieving a stable fit, and the fixing structure achieves fastening.

[0020] The aforementioned fixing structure includes a first pin hole 6 that is perpendicularly inserted into the conical section 42 and a second pin hole that is perpendicularly inserted into the cast-in-place pile sleeve 5. It also includes a fixing pin that is inserted into both the first pin hole 6 and the second pin hole. The fixing pin can stably connect the conical section 42 and the cast-in-place pile sleeve 5 and facilitate disassembly.

[0021] In summary, this utility model proposes a micro-hole grouting pile positioning device. By using information collected from a level and a ground hole alignment detection structure, the control system controls multiple telescopic outriggers 3 to extend and retract to adjust the top plate 1, the positioning column 4 below it, and the micro-hole grouting pile sleeve 5. This allows for the installation of photovoltaic support foundation piles on the ground without offset or tilt. Furthermore, by using a shadow image sensor as the ground hole alignment detection structure, the micro-hole grouting pile sleeve 5 can be vertically installed on flat ground, slopes, or other irregularly shaped ground surfaces, aligned with the vertically downward insertion holes in the ground, ultimately resulting in a vertically straight foundation pile without tilt or offset.
