Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic construction, and particularly relates to a jacking and transporting device for offshore photovoltaic support construction. Background Technique

[0002] At present, photovoltaic power generation is gradually moving towards the deep sea. To adapt to the marine environment, photovoltaic supports are generally designed as large platforms, resulting in an increase in the number of photovoltaic panels on each platform and an increase in construction difficulty. The largest domestic photovoltaic support is 60m x 35m. The hoisting and transportation of large photovoltaic supports generally use crawler cranes to hoist them onto flatbed trucks, and then the flatbed trucks transport them to the wharf. Then, large crawler cranes hoist them onto transport ships, and the transport ships transport them to the support installation location. More construction equipment is used and the construction speed is slower. Due to the large size of the hoisting structure, a 1250t or larger tonnage crawler crane is required for hoisting. The large crawler crane needs to be equipped with roadbed boxes, resulting in higher costs. In addition, the hoisting of large photovoltaic supports has high requirements for lifting tools, and the risk is relatively large, and it is greatly affected by wind loads. Content of the Utility Model

[0003] The purpose of the utility model is to provide a jacking and transporting device for offshore photovoltaic support construction.

[0004] On the one hand, this embodiment provides a jacking and transporting device for offshore photovoltaic support construction, which is characterized in that it includes a plurality of tire racks arranged under the photovoltaic support, a temporary anchoring structure arranged under the base of the photovoltaic support, an onshore jacking and transporting device connected to the temporary anchoring structure, and an offshore jacking and transporting device;

[0006] The offshore jacking and transporting device includes a transport ship and an anchoring bracket arranged on the transport ship. A hydraulic jacking device II is arranged on the anchoring bracket. The hydraulic jacking device II can be fixedly connected to the temporary anchoring structure through a detachable connecting piece.

[0007] The tire frame is used when the photovoltaic bracket is assembled to support the photovoltaic bracket. The specific number can be determined according to the actual situation. Generally, 8 tire frames are arranged in a matrix distribution. In addition, when the photovoltaic bracket is inclined, the tire frame needs to select a tire frame of appropriate height according to the inclination angle of the photovoltaic bracket; the transport vehicle adopts an existing transport vehicle that can realize synchronous walking, and it is best to have the function of turning 90 degrees on the spot. The transport vehicle is used to transport the photovoltaic bracket from the assembly site to the transport ship; the temporary anchoring structure is a temporary anchoring when the photovoltaic bracket is transported, which can limit the longitudinal and lateral displacement and vertical displacement of the photovoltaic bracket, and can resist the ship swaying force and wind load during the transportation of the photovoltaic bracket; the hydraulic jacking device is placed on the top of the transport vehicle. When the hydraulic jacking device is working, it lifts the photovoltaic bracket to make the photovoltaic bracket separate from the tire frame, which plays a role in removing the tire.

[0008] Furthermore, the temporary anchoring structure includes an anchoring platform, an anchoring steel plate fixedly arranged on the anchoring platform, a limiting base fixedly arranged on the anchoring steel plate, and an anchoring saddle buckled on the photovoltaic support base;

[0009] The anchor saddle is buckled on the base of the photovoltaic bracket and fixed to the anchor steel plate through the anchor cable.

The anchor cable can be made of high-strength flexible materials such as steel wire rope and cable. The anchoring platform is a connecting component between the land jacking and transportation device and the anchor steel plate during shore transportation, and a connecting component between the sea jacking and transportation device and the anchor steel plate during ship transportation. It is generally composed of a steel plate and longitudinal and transverse stiffening beams, and anchor holes are set on the surface for connection with the anchor bracket on the ship or the hydraulic jacking device.

[0010] Furthermore, four anchoring brackets are provided and located at the four corners of the anchoring platform, and the transport vehicle can pass through two adjacent anchoring brackets.

The cross braces can enhance the strength and stability of the anchor lattice columns and can also be made of steel pipe columns or steel section columns, which are fixedly welded to the anchor lattice columns.

[0014] Further, an installation groove that fits the upper end face of the photovoltaic support base is provided on the lower surface of the anchor saddle, and several grooves for placing the anchor cables are provided on the upper surface of the anchor saddle, which is convenient for binding and fixing the anchor cables.

[0015] Further, the lower end of the photovoltaic support base is inserted into the limit base, and a limit groove that matches the lower end of the photovoltaic support base is provided on the limit base. The inner wall slope of the limit groove matches the slope of the photovoltaic support base, and several stiffening ribs can be provided on the inner surface, with a general height of 35 cm.

[0016] Further, the gap between the inner wall of the limit groove and the outer wall of the photovoltaic support base is filled with a flexible material to limit the longitudinal and transverse displacement of the support and prevent damage to the paint due to hard contact.

[0017] Further, the photovoltaic support base and the photovoltaic support body are connected by several legs, and the anchor saddle is provided with a notch that cooperates with the legs. The notch can increase the contact area with the legs of the photovoltaic support; an outward-turning plate is provided at the outer edge of the notch, which can hold the legs while preventing the edge of the saddle from knocking against the legs.

[0018] Further, for the technical features not specifically described in this application, they can all be implemented by using existing technologies, such as the transport vehicle, the first hydraulic lifting device, the second hydraulic lifting device, etc.

[0019] Second, this embodiment provides a construction method for a lifting and transporting device for offshore photovoltaic supports, which is as follows:

[0020] First step, place the photovoltaic support on the jig or fix it to the jig through detachable connectors, and then assemble the photovoltaic support and the photovoltaic panel.

[0027] In the eighth step, after the transport vehicle drives the photovoltaic support to the designated position on the ship (the transport vehicle is located between two adjacent anchoring supports), the second hydraulic jacking device is started to jack up the photovoltaic support, so that the photovoltaic support is separated from the transport vehicle.

[0028] In the ninth step, the transport vehicle leaves the transport ship and proceeds with the jacking and transportation of the next photovoltaic support;

[0029] In the tenth step, after the transport vehicle drives away from the transport ship, the second hydraulic jacking device drops to make the anchoring platform contact the top support plate of the anchoring support, and then the anchor bolts are connected and fixed;

It only needs to be jacked away from the jig to be removed from the jig, replacing the original crawler crane hoisting scheme and reducing the hoisting height. The first hydraulic jacking device on the transport vehicle can adapt to the different heights of the bases of the photovoltaic supports (usually four), preventing uneven stress on the members during transportation.
