Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic pile foundation construction, in particular to a connection and fixing device for photovoltaic pile foundation construction equipment and a pile foundation. Background Art

[0002] Photovoltaic pile foundation is an important part of the construction of photovoltaic power stations. Traditional photovoltaic pile foundation is to drill holes in the ground and pour concrete to form a supporting structure for fixing photovoltaic panel brackets. With the development of current technology, most grassland photovoltaic projects now use steel pipe piles as the foundation of the bracket. Compared with traditional concrete pile foundations, it has the advantages of simple process, fast construction efficiency and long service life. After the later operation and maintenance period, it provides great convenience for re-construction or maintenance. Concrete piles are also easy to damage the soil and affect the growth of grassland plants, making steel pipe piles more cost-effective and thus widely used.

[0003] During the construction of existing steel pipe piles, a pile driver is generally used. The hydraulic device on the pile driver drives the steel pipe pile to rotate and press down, thereby driving the steel pipe pile below the ground, thereby completing the pile foundation construction. However, the existing pile driver and the steel pipe pile generally require manual assistance in installation and disassembly, which is not convenient for rapid installation and disassembly, resulting in low construction efficiency and increased construction costs. In order to solve this technical problem, the utility model proposes a connection and fixing device for photovoltaic pile foundation construction equipment and pile foundation. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, by providing components such as a buckle and an extrusion plate, after the pile top enters the interior of the fixed shell, the power mechanism drives the buckle to reset, and then the telescopic cylinder extends to drive the extrusion plate downward to squeeze the pile top, thereby fixing the pile top between the extrusion plate and the buckle, achieving the effect of easy fixation. After the piling is completed, the telescopic cylinder shortens to drive the extrusion plate to move away from the pile top, and the power mechanism drives the buckle to rotate 180 degrees, thereby moving the fixed shell away from the pile top, achieving the effect of easy disassembly, thereby solving the problem that the existing pile driver and steel pipe pile generally require manual assistance for installation and disassembly, which is not convenient for quick installation and disassembly, resulting in low construction efficiency and increased construction costs.

[0015] In the utility model, by providing components such as a detection mechanism, the pile top squeezes the sliding rod. When the sliding rod is squeezed, it moves close to the pressure sensor and squeezes the spring at the same time, so that the squeezing force of the spring on the pressure sensor increases.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a connection and fixing device for photovoltaic pile foundation construction equipment and pile foundation includes a fixing plate 1, and a connecting mechanism 2 is provided on the upper surface of the fixing plate 1. The connecting mechanism 2 includes a protective wall 201, and the lower surface of the protective wall 201 is fixedly connected to the fixing plate 1. A connecting column 202 is welded to the inner wall of the protective wall 201, and a connecting plate 203 is welded to the upper end of the connecting column 202. The connecting column 202 is fixed and supported by the protective wall 201. The protective wall 201 consists of a middle cylinder and surrounding inclined plates to increase the firmness between the fixing plate 1. A plurality of through holes are opened on the connecting plate 203, which can be fixed to the pile driver by bolts.

[0024] The lower surface of the fixed plate 1 is fixedly connected to the fixed shell 3, and the side of the fixed shell 3 is provided with a wheel axle 5, and the bottom of the wheel axle 5 is fixedly connected with a buckle 6. The outer surface of the wheel axle 5 is provided with a power mechanism 4, which includes a motor 401. The motor 401 is installed on the upper surface of the fixed plate 1, and the output shaft of the motor 401 passes through the fixed plate 1 and is fixedly connected to the wheel axle 5. The motor 401 can drive the wheel axle 5 to rotate, thereby driving the buckle 6 to rotate. The outer surface of the wheel axle 5 is rotatably connected to the fixed sleeve 402, and the outer surface of the fixed sleeve 402 is fixedly connected to the fixing frame 403. The outer surface of the fixing frame 403 is fixedly connected to the fixed shell 3, and the wheel axle 5 is limited and supported by the fixing sleeve 402, so that the wheel axle 5 can only rotate and cannot move up and down, so as to increase stability. The fixing frame 403 is fixed to the fixed shell 3 by multiple high-strength bolts to increase firmness.

[0025] A telescopic cylinder 7 is provided inside the connecting mechanism 2. The telescopic end of the telescopic cylinder 7 passes through the fixed plate 1 and extends to the bottom. The telescopic end of the telescopic cylinder 7 is fixedly connected to the extrusion plate 8. The outer surface of the extrusion plate 8 is slidably connected to the fixed shell 3. The upper surface of the telescopic cylinder 7 is fixedly connected to the inner top wall of the connecting column 202. The lower surface of the connecting column 202 is also fixedly connected to the fixed plate 1. When the telescopic cylinder 7 is extended, the extrusion plate 8 can be pushed downward to move the extrusion plate 8 downward, thereby squeezing the pile top 10.

[0026] A detection mechanism 9 is provided on the inner wall of the fixed plate 1, and the detection mechanism 9 includes a fixed cylinder 901. The lower surface of the fixed cylinder 901 is fixedly connected to the fixed plate 1, and the inner wall of the fixed cylinder 901 is slidably connected with a sliding rod 904. The outer surface of the sliding rod 904 is slidably connected to the fixed plate 1 and the extrusion plate 8. A pressure sensor 902 is installed inside the fixed cylinder 901, and a spring 903 is also provided inside the fixed cylinder 901. One end of the spring 903 is fixedly connected to the pressure sensor 902, and the other end of the spring 903 is fixedly connected to the sliding rod 904. When the sliding rod 904 is squeezed, it will move close to the pressure sensor 902 and squeeze the spring 903 at the same time, so that the extrusion force of the spring 903 on the pressure sensor 902 increases, and the pressure sensor 902 transmits the pressure signal to the external controller, thereby informing the driver of the pile driver.

[0027] A pile top 10 is provided inside the fixed shell 3 . The buckles 6 are triangular in shape, and their upper surfaces are horizontal. There are four buckles 6 , which can clamp the pile top 10 into the inside of the fixed shell 3 .

[0028] It should be noted that, in actual use, the device is connected to a pile driver via the connecting plate 203, and the motor 401 drives the wheel shaft 5 to rotate 180 degrees, so that the buckle 6 rotates to the outside of the fixed plate 1. The pile driver controls the device so that the pile top 10 enters the interior of the fixed shell 3. The pile top 10 squeezes the sliding rod 904, so that when the sliding rod 904 is squeezed, it moves close to the pressure sensor 902, and at the same time squeezes the spring 903, so that the squeezing force of the spring 903 on the pressure sensor 902 increases. The pressure sensor 902 transmits a pressure signal to an external controller, thereby informing the driver of the pile driver that the pile top 10 has entered the interior of the fixed shell 3 and passed the buckle 6, so as to prevent the buckle 6 from hitting the pile top 10 when resetting. After receiving the signal from the pressure sensor 902, the motor 401 is controlled to drive the wheel shaft 5 to rotate, thereby driving the buckle 6 to reset, and then the telescopic cylinder 7 is extended to drive the extrusion plate 8 to squeeze the pile top 10 downward, thereby fixing the pile top 10 between the extrusion plate 8 and the buckle 6, achieving the effect of facilitating fixation.

[0029] The steel pipe pile is then driven by a pile driver to rotate and drive the pile. After the pile driving is completed, the telescopic cylinder 7 is shortened to drive the extrusion plate 8 to move away from the pile top 10. The power mechanism 4 drives the buckle 6 to rotate 180 degrees, thereby moving the fixed shell 3 away from the pile top 10, achieving the effect of facilitating disassembly.
