Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaic construction, in particular to an automatic climbing device for an offshore photovoltaic truss. Background Art

[0002] Offshore photovoltaics is a technology for building and operating solar photovoltaic power generation systems in a marine environment. Compared with land-based photovoltaic power stations, under the same lighting conditions, offshore photovoltaic projects have advantages such as open sea surface without obstructions and long sunshine hours, which makes the light utilization efficiency higher and the power generation significantly increased.

[0003] Offshore photovoltaic power stations are mainly divided into two types: pile-based and floating. For pile-based power stations, the installation of steel trusses is an important part of the construction. At present, the installation of steel trusses mainly adopts the hoisting method. The trusses are purchased in small units and transported to the pre-supported component site. The staff assembles and welds the small unit trusses into a 24-meter-long complete truss at the dock or component yard, and then hoists the assembled trusses onto the transport ship. Finally, the trusses are hoisted to the top of the pre-set piles at sea by the hoisting ship for installation.

[0004] However, in the actual execution of the lifting operation, the complex and changeable offshore environment has become a key factor restricting construction efficiency and safety. Specifically, natural factors such as wind and waves can easily cause the lifted trusses to shake and deviate unpredictably, which not only directly affects the stable connection between the trusses and the pile foundations, reduces the accuracy and reliability of the installation, but also greatly increases the difficulty of operation and safety risks for construction personnel. In addition, the high rental and operating costs of lifting vessels and auxiliary heavy equipment constitute an additional burden that cannot be ignored in the construction of offshore photovoltaic power stations. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an automatic climbing device for offshore photovoltaic trusses with simple operation, stable docking and low cost in view of the deficiencies in the prior art.

[0009] The truss transfer mechanism includes a lifting frame horizontally arranged on the outside of the pile foundation, a positioning wheel group is provided between the inner side of the lifting frame and the pile foundation, the positioning wheel group includes a driving wheel matched with the climbing track, and a lifting drive mechanism providing power for the driving wheel is provided on the lifting frame;

[0010] A supporting frame is extended to the left and right sides on the outer side of the lifting frame, and a horizontal guide rail is provided above each supporting frame along the front-to-back direction.

A translation driving mechanism for driving the hopper trolley to slide forward and backward along the horizontal guide rail is provided on the supporting frame. The two ends of the horizontal guide rail are respectively located at the front and rear sides of the pile foundation.

[0012] The technical problem to be solved by the utility model can be further achieved through the following steps: a stabilizing rod is provided on the lower part of the lifting frame extending downward, and a stabilizing wheel matching the climbing track is provided on the stabilizing rod.

[0013] The technical problem to be solved by the utility model can be further achieved through the following steps: the lifting drive mechanism includes a drive motor, and the output end of the drive motor is connected to the driving wheel for transmission.

[0014] The technical problem to be solved by the utility model can be further achieved through the following steps: the translation drive mechanism includes a driving cylinder, which is arranged in parallel on one side of the horizontal guide rail, and the output end of the driving cylinder faces forward and is fixedly connected to the hopper trolley through a connecting plate.

[0015] The technical problem to be solved by the utility model can be further achieved by the following steps: the upper end of the climbing track is flush with the upper end surface of the pile foundation.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting up a truss transfer mechanism, the truss is loaded onto the hopper trolley, and the truss is steadily transported to the top of the pile foundation through the cooperation of the positioning wheel group and the climbing track, thereby effectively avoiding the influence of the complex offshore environment, improving the accuracy and reliability of the connection between the truss and the pile foundation, and reducing the safety risks in the construction process; at the same time, the utility model transforms the hoisting process of the truss into a more economical automatic climbing process, reduces the dependence on heavy hoisting equipment, and significantly reduces the construction cost.

DETAILED DESCRIPTION

[0024] The specific technical solutions of the present invention are further described below so that those skilled in the art can further understand the present invention, but it does not constitute a limitation on the rights thereof.

The positioning wheel group includes a driving wheel 4 matched with the climbing track 2, and a lifting drive mechanism for providing power to the driving wheel 4 is provided on the lifting frame 3.

[0028] A support frame 5 is extended to the left and right sides of the outer surface of the lifting frame 3. The support frame 5 is fixedly connected to the lifting frame 3 as a whole, and the support frame 5 includes at least two support rods arranged along the left and right directions. A horizontal guide rail 6 is provided above each support frame 5 along the front-to-back direction, and the horizontal guide rail 6 is fixedly connected to the support frame 5. A hopper trolley 7 for loading the truss 19 is provided above the horizontal guide rail 6, and a guide wheel 8 matching the horizontal guide rail 6 is provided at the lower part of the hopper trolley 7. A translation drive mechanism for driving the hopper trolley 7 to slide forward and backward along the horizontal guide rail 6 is provided on the support frame 5. The two ends of the horizontal guide rail 6 are respectively located at the front and rear sides of the pile foundation 18. When the hopper trolley 7 slides to the front end of the horizontal guide rail 6, there is an anti-collision gap between it and the climbing track 2. As shown in FIG. Figure 3-5 As shown, the significance of the anti-collision gap is to prevent the hopper trolley 7 from interfering with the climbing track 2 when lifting.
