[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A temporary transportation device for installing photovoltaic panels on a marine square pyramid steel pipe grid includes a temporary hoop device, a steel wire rope, a fixed bottom plate, and a pulley assembly. There are two groups of temporary hoop devices, and the two groups of temporary hoop devices are symmetrically arranged along the width direction of the steel pipe grid. Each group of temporary hoop devices includes two groups of temporary hoop components. The two groups of temporary hoop components are arranged along the length direction of the steel pipe grid and are respectively located at both ends of the steel pipe grid. The temporary hoop components are fixedly connected to the upper chord steel pipe of the steel pipe grid. A steel wire rope is tensioned and connected between the two groups of temporary hoop components in each group of temporary hoop devices. The two steel wire ropes in the two groups of temporary hoop devices form a sliding track. The fixed bottom plate is arranged between the two steel wire ropes. The pulley assembly is fixedly connected to the fixed bottom plate. The pulley assembly is slidably connected to the steel wire rope. The pulley assemblies on the two steel wire ropes are symmetrically arranged. The photovoltaic panel is placed on the fixed bottom plate. The fixed bottom plate moves along the sliding track through the pulley assembly to realize the transportation and movement of the photovoltaic panel.

[0006] Furthermore, the temporary hoop assembly includes a locking clip and a lower hanging connecting frame. The bottom of the locking clip is fixedly connected to the lower hanging connecting frame through a lower bolt assembly. The upper chord steel pipe is limited and fixed in the locking clip. The lower hanging connecting frame is connected to the wire rope. The upper chord steel pipe is limited and fixed by the locking clip to achieve a stable connection between the temporary hoop assembly and the steel pipe grid. It is easy to assemble and disassemble, and can be quickly disassembled and assembled, reducing construction difficulty and improving construction efficiency. The lower bolt assembly can effectively ensure the firmness and reliability of the connection between the locking clip and the lower hanging connecting frame, improve structural safety, and also facilitate the connection between the temporary hoop assembly and the wire rope.

[0007] Furthermore, the locking buckle includes two locking cards, which are symmetrically arranged on both sides of the lower hanging connecting frame. The bottoms of the two locking cards are fixedly connected to the lower hanging connecting frame through the lower bolt assembly, and the tops of the two locking cards are connected by the upper bolt assembly. The upper chord steel pipe is limited and fixed to the middle of the two locking cards. The overall structural design is ingenious and reasonable. The locking buckle adopts two locking cards design, and the bottoms of the two locking cards and the lower hanging connecting frame are connected through the lower bolt assembly to achieve a firm installation between the two locking cards and the lower hanging connecting frame, and the tops of the two locking cards are also connected with the upper bolt assembly. By adjusting the tightness of the upper bolt assembly, it can be ensured that the locking buckle is firmly fixed on the upper chord steel pipe, effectively preventing the connection between the two from shaking or falling off, thereby ensuring the structural stability of the entire conveying device, and this design makes the locking buckle applicable to upper chord steel pipes of different specifications and sizes, improving the versatility of the temporary clamp assembly and expanding the scope of application.

[0008] Furthermore, the middle part of the locking card is an arc-shaped card segment. After the two locking cards are assembled, an arc-shaped card slot is formed between the two arc-shaped card segments, and the upper chord steel pipe is limited and fixed in the arc-shaped card slot. The design of the arc-shaped card segment is more ingenious and reasonable, so that an arc-shaped card slot is formed between the middle parts of the two locking clips. Combined with the design of the upper chord steel pipe as a round tube, the contact area between the locking clip and the upper chord steel pipe can be increased, so that the locking card and the upper chord steel pipe fit tightly to form a stable fixed structure, reduce the relative displacement between the upper chord steel pipe and the locking clip, etc., improve stability, and this design is also easy to install and disassemble.

[0009] Furthermore, a wire rope locker is provided on the lower hanging connecting frame, and the wire rope is passed through and connected to the wire rope locker. The wire rope locker directly adopts the conventional wire rope locker on the market. The wire rope locker can firmly fix the end of the wire rope to prevent the wire rope from falling off or loosening during the use of the conveying device, thereby improving the safety of use.

[0010] Furthermore, the pulley assembly includes a pulley and a connecting seat. The pulley is arranged on the connecting seat, and the pulley is rollingly arranged above the steel wire rope. The design is reasonable. The connecting seat is used to support and fix the pulley. The steel wire rope is exactly located between the connecting seat and the pulley, and the steel wire rope is limited in the rolling chute at the bottom of the pulley. Through the rolling of the pulley on the steel wire rope, the fixed bottom plate drives the photovoltaic panel to move smoothly along the sliding track, realizing the stable transportation of the photovoltaic panel, improving the installation efficiency of the photovoltaic panel, and reducing the labor cost.

[0011] Furthermore, a suspension connecting frame is fixedly connected below the connecting seat. The bottom of the suspension connecting frame is connected and fixed to the fixed bottom plate through a connecting piece. The design is reasonable. Through the design of the suspension connecting frame, the installation and fixation between the pulley assembly and the fixed bottom plate can be facilitated.

[0012] Furthermore, the connecting piece is a connecting bolt. The design is reasonable. Using the connecting bolt as the connecting piece can facilitate the actual assembly and disassembly, and can also ensure the connection strength between the suspension connecting frame and the fixed bottom plate.

[0013] Furthermore, the connecting seat and the suspension connecting frame are welded and fixed. Welding and fixing can ensure the connection firmness and reliability between the connecting seat and the suspension connecting frame, making the two welded and fixed into a whole, improving the overall bearing capacity and structural safety.

[0014] Furthermore, at least two groups of pulley assemblies are arranged on each steel wire rope. A number of pulley assemblies located on the same steel wire rope are evenly distributed along the corresponding side edges of the fixed bottom plate. If only two groups of pulley assemblies are arranged on each steel wire rope, a total of four groups of pulley assemblies are arranged on the two steel wire ropes. The four groups of pulley assemblies are preferably arranged at the four corners of the fixed bottom plate, and the number of pulley assemblies on the steel wire rope can also be increased according to requirements to ensure the overall structural bearing capacity, but it must be ensured that the pulley assemblies on the two steel wire ropes are symmetrically arranged and evenly distributed along the corresponding side edges of the fixed bottom plate, so as to ensure the overall structural balance and stability and improve the use safety.
