Description

Technical Field

[0001] The utility model belongs to the technical field of electric power and building construction, and specifically relates to a device for quickly installing a middle column of a flexible photovoltaic support. Background Art

[0002] Because the height of the main cable structure of the mountain flexible photovoltaic support varies greatly with the terrain, the overall height difference of each span of the main cable is large, and the span lengths vary. In order to improve the overall stability and safety of the flexible support, each span of the support is often equipped with middle columns between the spans in addition to the end piles at both ends. The middle columns and single-end columns are basically prefabricated pipe piles. When the middle column is hinged with two pipe piles, it is necessary to press a pipe pile into the soil in advance, and the exposed part is hinged with the upper pipe pile. After the two pipe piles are hinged, the upper pipe pile needs to be erected vertically. The traditional column erection process usually requires construction personnel to use hinges, traction ropes or cranes for construction. This method not only has high safety risk factors, high construction costs such as manpower, materials and machinery, and slow construction efficiency, but also the construction quality cannot be guaranteed. In actual engineering applications, especially large-span mountain photovoltaics, faced with adverse factors such as harsh terrain conditions, no motor vehicle lanes, inability to fix hinged traction ropes, inability to reach cranes, and high safety risks, the efficiency of column installation is low, the quality of engineering construction is difficult to guarantee, and the overall column installation qualification rate is affected.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 3As shown, the utility model provides a quick installation device for the middle column of a flexible photovoltaic support, the middle column includes a lower pipe pile 9 and an upper pipe pile 10 which are hinged to each other, the quick installation device includes a fixed frame 1, a control unit and a hydraulic jacking device 3, the fixed frame 1 is connected to the lower pipe pile 9 in a detachable manner, the hydraulic jacking device 3 is rotatably installed in the fixed frame 1, the telescopic end of the hydraulic jacking device 3 is rotatably connected to the upper pipe pile 10, and the control unit is used to control the hydraulic jacking device 3 to extend and retract.

[0018] The lower pipe pile 9 is buried in the ground with the top exposed, and the bottom end of the upper pipe pile 10 is rotatably connected to the top of the lower pipe pile 9 through the hinge structure 11. At this time, the fixed frame 1 is fixedly connected to the lower pipe pile 9, and the hydraulic jacking device 3 is rotatably installed in the fixed frame 1, and its telescopic end is rotatably connected to the upper pipe pile 10. When the control unit controls the telescopic end of the hydraulic jacking device 3 to extend, the upper pipe pile 10 can be pushed to rotate relative to the lower pipe pile 9 and adjusted to an upright state. Conversely, when the control unit controls the telescopic end of the hydraulic jacking device 3 to contract, the upper pipe pile 10 can be driven to be laid flat.

[0019] The fixed frame 1 is welded by a square tube and a bottom plate, and two first pile grippers 2 are fixedly connected to one side of the fixed frame 1, and the two first pile grippers 2 can be clamped on the lower pipe pile 9, and the telescopic end of the hydraulic jacking device 3 is rotatably connected to the second pile gripper 4, and the second pile gripper 4 can be clamped on the upper pipe pile 10. The hydraulic system has a simple structure, small size, light weight, easy installation and maintenance, and has functions such as adjustment, control, protection and automation, strong adaptability and high transmission efficiency, stable and reliable power transmission, and easy operation.

[0020] The first pile gripper 2 and the second pile gripper 4 are both composed of two semicircular structures, which can be sleeved on the pipe pile, one end of which is hingedly connected, and the other end is fastened by bolts and nuts. Since the second pile gripper 4 is rotatably connected to the telescopic end of the hydraulic jacking device 3, the second pile gripper 4 can also adjust its angle during the rotation of the upper pipe pile 10, so that the second pile gripper 4 always maintains a state of close fit with the upper pipe pile 10.

[0021] The control unit includes a control box 5, a power line 6, an oil pipe 7 and a switch 8. The two ends of the oil pipe 7 are respectively connected to the control box 5 and the hydraulic jacking device 3, and the two ends of the power line 6 are respectively connected to the control box 5 and the switch 8. The expansion and contraction of the hydraulic jacking device 3 can be controlled by the switch 8.

[0022] In summary, the overall use process of the utility model is as follows: after the lower pipe pile 9 is pressed, the upper pipe pile 10 is first moved to the installation position, so that the hinge of the two is initially installed. Then the device is placed horizontally at the appropriate position of the root of the lower pipe pile 9 and connected and fixed with the lower pipe pile 9 by the first pile gripper 2, so that the center of the fixed frame 1 coincides with the center of the upper pipe pile 10, and the second pile gripper 4 is fastened and connected with the upper pipe pile 10 at the appropriate position. After the preparation is completed, the control unit is turned on, and the upper pipe pile 10 is driven to rotate around the hinge structure 11 through the lifting of the hydraulic jacking device 3, and rotates from a horizontal state to an upright state. During the rotation process, the root of the hydraulic jacking device 3 rotates accordingly to ensure the integrity of the device. Finally, the hinged parts of the upper pipe pile 10 and the lower pipe pile 9 are finally fastened, the first pile gripper 2 and the second pile gripper 4 are removed, and the device is moved to the next position. The use of this device can save manpower and machinery, and is safe and quick to operate.
