Technical Field

[0001] The utility model relates to the technical field of photovoltaic construction, and particularly relates to a special lifting tool for loading and unloading precast pipe piles. Background Technique

[0002] Photovoltaic cell modules (also called solar panels, photovoltaic modules) are the core part of a solar power generation system and also the most important part. Its function is to convert solar energy into electrical energy, which can be sent to a storage battery for storage or drive a load to work. The quality and cost of photovoltaic cell modules will directly determine the quality and cost of the entire system. Component products with high power, high efficiency, high reliability, and high power generation are the key to promoting the photovoltaic power generation into the era of full parity.

[0003] Photovoltaic precast pipe piles are a new type of component that combines photovoltaic panels with pipe pile structures, and are mainly applied to the construction of photovoltaic power stations. Compared with traditional concrete foundations, photovoltaic precast pipe piles have higher installation efficiency and stronger bearing capacity. In large-scale ground photovoltaic power stations, photovoltaic precast pipe piles can quickly complete foundation construction, shorten the construction period, and reduce costs. At the same time, with the continuous development and popularization of photovoltaic technology, photovoltaic precast pipe piles will play a more important role in future photovoltaic projects and make greater contributions to promoting the green energy revolution. Excellent bearing performance can ensure the safe and stable operation of photovoltaic panels and improve the overall power generation efficiency of the power station.

[0004] However, there are some problems in the prior art: when installing photovoltaic precast pipe piles, a crane needs to be used to lift the photovoltaic precast pipe piles with ropes and transport them to a predetermined position. During the transportation process, the photovoltaic precast pipe piles will swing in the air, resulting in the deviation of the center point of the lifting tool clamping the photovoltaic precast pipe piles, causing the photovoltaic precast pipe piles to slip and pose a danger during actual use. Therefore, we propose a special lifting tool for loading and unloading precast pipe piles. Content of the Utility Model

The adjusting mechanism passes through the strip-shaped through hole and is fixedly connected to the movable clamping plate, and can adjust the position of the movable clamping plate to cooperate with the fixed clamping plate to clamp the pipe wall of the pipe pile body.

[0007] Further, the adjusting mechanism includes a screw that can rotate inside the assembly hole, a threaded seat sleeved on the screw, and a fixed sleeve for driving the screw to rotate. The threaded seat is sleeved and threadedly connected with the screw, and a limit cover is welded to one end of the screw located at the lower end of the connecting plate. A rotating cover is formed on one side of the fixed sleeve, and the other side extends into the assembly hole and is fixedly sleeved and connected with the screw. A connecting block is integrally formed on the outer wall of the threaded seat, and the connecting block passes through the strip-shaped through hole and is welded to the movable clamping plate.

[0008] Further, a polygonal shaft section is formed at one end of the screw away from the limit cover, and a polygonal groove body matching the polygonal shaft section is provided at one end of the fixed sleeve. The screw is sleeved and connected with the fixed sleeve through the polygonal shaft section.

[0009] Further, a small-diameter threaded shaft is formed at the outermost end of the polygonal shaft section of the screw, and a through hole for the small-diameter threaded shaft to pass through is provided on the fixed sleeve. The small-diameter threaded shaft passes through the through hole on the fixed sleeve and is threadedly connected with a nut to limit the sleeved position of the fixed sleeve.

On one side of the connecting plate 1 close to the pipe pile body 5, a fixed clamping plate 4 is welded, and an adjustable movable clamping member is provided; a connecting hole 13 is provided on the movable clamping member, and a U-shaped shackle 6 is connected to the movable clamping member through the connecting hole 13. A through assembly hole 9 is provided on the connecting plate 1. On one side of the connecting plate 1 close to the pipe pile body 5, a strip-shaped through hole 8 communicating with the assembly hole 9 is provided. A detachable adjusting mechanism 2 is installed inside the assembly hole 9; the adjusting mechanism 2 passes through the strip-shaped through hole 8 and is fixedly connected to the movable clamping plate 3; thereby, the position of the movable clamping plate 3 can be adjusted according to the wall thickness of the pipe pile body 5, so that it cooperates with the fixed clamping plate 4 to facilitate clamping and fixing of the pipe wall of the pipe pile body 5, improving the practicability and applicable range of the sling 7. At the same time, the connecting hole 13 is located on the movable clamping plate 3. By using the movable clamping plate 3 in combination with the U-shaped shackle 6, the installation efficiency of the hoisting rope is greatly improved, meeting the requirements of construction specifications, greatly reducing the risk of the pipe pile slipping, and at the same time facilitating the operator to place the pipe pile in time.

[0021] As Figure 2 , Figure 3 and Figure 4 shown in the figure, the adjusting mechanism 2 includes a screw 10 that can rotate inside the assembly hole 9, a threaded seat 11 sleeved on the outer wall of the screw 10, and a fixed sleeve 12 that drives the screw 10 to rotate. The threaded seat 11 is sleeved and threadedly connected with the screw 10. A limiting cover 15 is welded to one end of the screw 10 located at the lower end of the connecting plate 1; a rotating cover 17 is formed on one side of the fixed sleeve 12, and the other side extends into the assembly hole 9 and is fixedly sleeved and connected with the screw 10; a connecting block 16 is integrally formed on the threaded seat 11, and the connecting block 16 passes through the strip-shaped through hole 8 and is welded to the movable clamping plate 3. Rotate the rotating cover 17 on one side of the fixed sleeve 12 to make the fixed sleeve 12 drive the screw 10 to rotate. While the screw 10 rotates, since the threaded seat 11 is threadedly connected with the screw 10 and at the same time the threaded seat 11 is limited by the strip-shaped through hole 8, the threaded seat 11 can drive the movable clamping plate 3 to move up and down, so that the movable clamping plate 3 cooperates with the fixed clamping plate 4 to realize clamping and fixing according to the wall thickness of the pipe pile body 5.

[0022] The fixed sleeve 12 and the screw 10 can be fixedly sleeved and connected in the following way: As Figure 4 shown in the figure, in this embodiment, the end of the screw 10 far from the limiting cover 15 is processed into a shaft section 14 with a polygonal cross-section, such as: a shaft section with a hexagonal cross-section or a shaft section with an octagonal cross-section; at the same time, a polygonal groove body matching it is processed at one end of the fixed sleeve 12 so that it can be sleeved. In addition, a small-diameter threaded shaft 18 is processed at the outermost end of the screw 10, and a through hole 19 that meets the requirement for the small-diameter threaded shaft 18 to pass through is provided on the fixed sleeve 12. A nut 20 is used to threadedly connect with the small-diameter threaded shaft 18 at the through hole 19 to limit the sleeved position of the fixed sleeve 12.
