Description

Technical Field

[0001] The present application relates to the field of boat folding and launching technical equipment, and in particular to a carrying device for a foldable boat. Background Art

[0002] At present, the folding, launching and transportation of steel motorboats usually require the use of a motorboat cart, and the motorboat needs to be moved on the motorboat cart during the folding and launching process. In order to achieve this process, rollers are usually arranged at the rear of the motorboat cart so that the bottom of the boat body moves on the rollers. This design can make the folding, launching and transportation process of the motorboat more convenient and efficient.

[0003] For steel motorboats, their relatively strong structure enables local support of rollers. However, with the widespread use of composite materials in motorboat manufacturing, such as fiberglass, composite boat hulls are usually designed to reduce weight, increase strength and corrosion resistance. Therefore, when using rollers for retrieval and transportation, special consideration needs to be given to the way the rollers support the composite boat hull to avoid damage to the hull. The use of boat carts for retrieval and deployment may result in damage to the hull due to the limited bearing capacity of the local hull structure.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the existing boat vehicle can only carry small motorboats with a weight of no more than 10 tons and a length of no more than 8 meters. Boats with a weight of 20 to 30 tons and a length of 12 to 20 meters cannot be carried by the entire vehicle. Summary of the invention

Figure 1 , Figure 2 A carrying device for retractable boats includes a tractor 1, which includes a head end of the tractor 1 located on one side and a tail end of the tractor 1 located on a side away from the head end of the tractor 1. The direction from the head end of the tractor 1 to the tail end of the tractor 1 is the length direction of the tractor 1.

[0035] A trailer chassis 2 is disposed on one side of the tractor 1, and the tractor 1 can drive the trailer chassis 2 to move. A tray 4 is horizontally disposed on the trailer chassis 2, and a plurality of first rollers 21 are disposed between the trailer chassis 2 and the tray 4, the mounting ends of the first rollers 21 are fixedly connected to the trailer chassis 2, and the roller ends of the first rollers 21 are relatively abutted against the bottom wall of the tray 4 to roll, so that the tray 4 can move along the length direction on the trailer chassis 2 under the rolling of the first rollers 21.

[0036] A flip assembly 3 is relatively arranged on the trailer chassis 2, and the flip assembly 3 is used to drive the pallet 4 to move and flip relatively on the trailer chassis 2, so as to facilitate loading and unloading of the boat located above the pallet 4 through the pallet 4.

[0037] Reference Figure 3 , Figure 4 The flip assembly 3 includes a control base 31, and the control base 31 includes a flip part 311 on the side away from the head end of the tractor 1. A sliding part 312 is slidably connected to the side of the flip part 311 close to the head end of the tractor 1. The sliding part 312 slides relatively with the trailer chassis 2, so that the length of the control base 31 along the length direction can be adjusted by the sliding part 312. The end of the flip part 311 away from the head end of the tractor 1 is hinged to the trailer chassis 2, and the hinge point of the flip part 311 and the trailer chassis 2 is lower than the upper surface of the trailer chassis 2.

[0038] The sliding part 312 includes a vertically arranged connecting part 3121, the top of which is hingedly arranged with the end of the tray 4. A sliding part 3122 is horizontally arranged at the bottom of the connecting part 3121, and the side of the sliding part 3122 facing away from the head end of the tractor 1 is relatively connected to the flip part 311 and relatively slidably connected.
