Boat trailer of automatic centering structure

Abstract

The invention discloses a boat trailer of an automatic centering structure. The boat trailer comprises a trailer frame, wheels, load-bearing rolling wheel devices, guide rolling wheel devices, a V-shaped guide plate and an uplifting wheel, and the V-shaped guide plate is located at the tail of the trailer. The trailer frame comprises a side frame and a supporting frame. The load-bearing rolling wheel devices and the guide rolling wheel devices are all fixed to the two ends of the supporting frame through supporting rods and all comprise swing arm mechanisms. Each swing arm mechanism comprises a swing arm and supporting wheels. The two ends of each swing arm are provided with supporting shafts. The supporting wheels are pivoted to the supporting shafts. The swing arms are pivoted to load-bearing beams or guide beams through pivots in a swing mode. Conical surfaces are arranged at the two ends of through holes of the supporting wheels. The V-shaped guide plate is arranged between the two guide rolling wheel devices. The uplifting wheel is located in the middle of the V-shaped guide plate. A boat can be automatically centered when transported on the trailer, sea waves and other external influence factors are avoided, and later-period correction is not needed; and in addition, the supporting wheels on the swing arms can cater to the inclined plane of the bottom of the boat, and enough support is given to the boat.

Description

technical field [0001] The invention relates to the field of boat trailers, in particular to a boat trailer with an automatic centering structure. Background technique [0002] Most of the existing boat trailers have support wheels, and the function of the support wheels is to support the boat to hold up the hull, and then fix the boat by tools such as ropes, so that the fixed boat can be towed. [0003] However, due to some yachts with large weight and volume, it is not suitable to use the above simple trailer for fixing, the reasons are as follows: [0004] 1. For small and medium-sized yachts, the bottom is V-shaped, and the vertical support alone is not enough, and the bottom of the inclined plane needs to be supported; [0005] 2. When the boat is being towed, the most difficult step should be how to lift the hull in the water and transport it to the top of the trailer; [0006] 3. When the boat is loaded onto the trailer, the boat can be accelerated to the trailer wi...

Problems solved by technology

[0006] 3. When the boat is loaded onto the trailer, the boat can be accelerated to the trailer without mechanical lifting. However, in the actual process of loading the boat, there will be water currents and waves that will affect the angle of the boat, making it move forward. It is difficult to maintain the centering angle in the middle, how to realize the automatic alignment in the water and rush to the trailer, still need to improve the trailer
