Description

Technical Field

[0001] The utility model relates to a frame structure, in particular to a frame structure of a yacht sliding trailer, belonging to the field of yacht trailers. Background Art

[0002] A yacht is a vessel with a mechanical propulsion device that is used only by the yacht owner for sightseeing, leisure and entertainment. A yacht is a high-end durable consumer product for water entertainment, which integrates navigation, sports, entertainment, leisure and other functions to meet the needs of individuals and families to enjoy life.

[0003] The production and assembly of yachts are completed in yacht production workshops or factories. After the yacht is completed, it needs to be transported to the seaside by vehicles and other means of transportation, and lifted into the water by cranes and other lifting equipment. However, there are few parts on the yacht that can be connected to the lifting equipment, so there are certain safety hazards in the lifting process. For some new yachts, it is even impossible to launch them by lifting. In addition, the terrain restrictions of the area where the yacht is launched by lifting are large, and the cost is also high, which brings great trouble to users. For this reason, some small yachts use the trailer towing method for inclined launching. The trailer has rollers, similar to a cart. After the yacht is placed on the trailer and fixed, the trailer can be moved by a tractor. When a small yacht is launched on shore or in the water with a trailer, the trailer pulls the yacht ashore or slides it into the water along a yacht-specific slide with a certain slope.

[0004] The existing trailer can be used for the storage and transportation of yachts. It facilitates the movement of yachts and forms a support platform for parking yachts, thus avoiding damage to yachts caused by uneven support force and shaking imbalance during transportation and parking. It can be said that yachts are supported by yacht trailers for most of the time after leaving the water. However, when the yacht is launched into the water using the existing trailer, it needs to be at a location with a special slideway for yachts. During the launching process, the tractor needs to reverse along the special slideway for yachts, push the trailer with the yacht to the bottom of the slideway until the trailer and the yacht enter the water, then untie the yacht, and manually push the yacht or the personnel on the yacht to start the yacht, so that the yacht is separated from the trailer. The whole process is time-consuming and labor-intensive, and the operation is difficult. In view of this, the applicant has invented a sliding trailer. After the sliding trailer is installed on the trailer, it can not only realize the storage and transportation of yachts, but also realize the automatic entry of yachts into the water, and the requirements for the entry point are not high. It is equivalent to designing the existing trailer with wheels into a split structure, that is, a trailer plus trailer structure.

[0026] Example 1

[0027] like Figure 1-Figure 5As shown: a frame structure of a yacht sliding trailer, which needs to be installed on a trailer 1 for use. The frame structure of the yacht sliding trailer includes a slide rail 2 and a main frame installed on the slide rail 2. The slide rail 2 is fixedly installed on the trailer 1. The main frame can slide forward and backward along the slide rail 2 and stop, thereby driving the yacht on the main frame to slide. When it stops, the yacht on the main frame slides out of the trailer under the action of inertia and its own gravity to achieve launching. The main frame includes a frame 3 and two support beams 4 arranged on the frame 3. When the yacht is placed on the main frame, the bottom of the yacht is supported by the support beams 4 respectively. When the yacht slides out along the support beam 4, since its bottom contacts the support beam 4, a soft protective layer can be wrapped outside the support beam 4 to reduce the wear of the bottom of the yacht. The inclination angle of the upper surface of the support beam 4 is adjustable, so it can be suitable for the storage, transportation and launching of yachts of different specifications and models. The main frame is connected to the trailer 1 through a buckle-type tensioning belt 5 to keep the two relatively fixed, preventing the main frame and the slide rail 2 from sliding relative to each other during transportation, etc., and a fixing belt 6 for holding the yacht is provided at the front end of the main frame to prevent the yacht and the support beam 4 from sliding relative to each other during transportation, etc. When the yacht needs to be launched, the buckle-type tensioning belt 5 and the fixing belt 6 need to be untied.
