[0001] The utility model relates to the technical field of trailers, in particular to a multifunctional boat trailer for water rescue. Background Art
[0002] A boat trailer is a device for transporting and moving boats. Boats are needed for water sports or for flood relief. Before use, the boats need to be transported to the vicinity of the water. The trailer can well solve the problem of supporting and transporting the boats before they are launched into the water and after they leave the water. For example, in the patent document with Chinese patent application number 202322222235.2 and publication date 2024.05.03, a yacht trailer is disclosed, including a trailer bracket, a first support rib, a second support rib, a third support rib, a horizontal supporting wheel and a wheel; the trailer bracket is in a "V" shape, and the trailer The bracket is fixedly connected to a first supporting rib, a second supporting rib and a third supporting rib, and horizontal supporting wheels are installed on the trailer bracket, the second supporting rib and the third supporting rib. A wheel is fixedly connected under the trailer bracket, and two first supporting wheel assemblies are fixedly connected side by side to the first supporting rib, the second supporting rib is fixedly connected to the second supporting rib, and the third supporting rib is fixedly connected to the third supporting rib. The third supporting wheel assembly consists of a plurality of supporting wheels and a long cross bar, and the long cross bar is fixedly connected to supporting wheels arranged side by side, which solves the problem that when a yacht needs to be towed, it is difficult to transport it onto a trailer, and the existing yacht trailers are incompatible with yachts of different models.
[0003] However, the structure of the above patent document cannot adjust the height between the boat and the trailer. In the process of directly loading and unloading the boat onto the vehicle in the water, a special ramp with a certain slope is required. At the same time, with the help of manpower, the head of the boat can be lifted and then pulled onto the trailer with a winch. This requires multiple people to operate and is time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of the utility model is to provide a multifunctional boat trailer for water rescue, which can adaptively adjust the height between the boat and the trailer on different ground surfaces, and provide an adaptive ramp for the boat to load and unload, which is practical and reliable.

[0006] The above arrangement, by arranging an opening on the frame and a limit seat at the opening, and at the same time arranging a traction beam to be rotatably hinged with the frame through a hinge seat, so that when the boat presses against the rear end of the frame, the front end of the frame can be rotated around the hinge by manually unlocking the locking device. This process causes the front end of the frame to be lifted, and the rear end of the frame is adaptively pressed down by the boat, so that the frame is tilted to form a ramp adapted to the boat, which is convenient for the boat to adaptively adjust the height between the boat and the trailer to achieve loading and unloading on different grounds; by arranging a buffer device between the traction beam and the frame, in the process of rotating and lifting the front end of the boat, the traction effect of the buffer device can prevent the boat from rotating too much and being unable to be controlled when pressing against the rear end of the frame, thereby affecting the loading and unloading of the boat.
[0007] Furthermore, the front end of the frame is arranged in a "V" shape, one or more parallel and oppositely arranged guide wheel groups are fixedly provided on the frame, the rear end of the frame is provided with symmetrically arranged support wheels, and the bottom of the frame is provided with wheels.
[0008] With the above arrangement, when the boat presses against the rear end of the frame, the rear end of the frame will drop to the ground. By providing support wheels, it is possible to prevent the rear end of the frame from colliding with the ground. By providing a guide wheel group on the frame, it is convenient for the boat to slide onto the frame along the guide wheel group, thereby reducing friction with the frame.
[0009] Furthermore, the limit clamping seat includes a limit pin, a limit roller, a clamping seat welding plate 1 and a clamping seat welding plate 2, one end of the clamping seat welding plate 1 is welded and fixed on one side of the opening, one end of the clamping seat welding plate 2 is welded and fixed on the other side of the opening, and the limit pin is arranged between the clamping seat welding plate 1 and the clamping seat welding plate 2 and its two ends are respectively fixed on the other end of the clamping seat welding plate 1 and the other end of the clamping seat welding plate 2.
[0010] With the above arrangement, after the traction beam is inserted between the first and second welding plates of the clamping base, the limit pin can limit the height of the traction beam moving upward in the clamping base, thereby keeping the front and rear ends of the frame in balance.
[0011] Furthermore, a fixed shaft is fixed between the first and second clamping base welding plates, the fixed shaft is arranged above the limiting pin, and the limiting roller is sleeved on the fixed shaft.
[0012] The above arrangement makes it easy for the traction belt to pass through the bottom of the limiting roller to pull the boat. At the same time, the limiting roller limits the traction belt and can also reduce friction.
[0013] Furthermore, the locking device includes a positioning pin and a locking piece, one end of the positioning pin is provided with a limit block, and the other end of the positioning pin passes through the through holes relatively arranged on the base welding plate 1 and the base welding plate 2 to fix the limit base on the traction beam and is detachably connected to the locking piece.
[0014] The above arrangement enables, after the boat is loaded onto the frame, the front end of the frame to be pressed down until the traction beam is clamped between the first and second clamping seat welding plates, and then the positioning pin is inserted between the clamping seat welding plate and the traction beam, thereby locking the front end of the frame on the traction beam and achieving horizontal balance of the frame.
[0015] Furthermore, a lifting electric travel mechanism is fixedly provided on the other end of the traction beam, a hand-operated electric winch is provided between the locking device and the lifting electric winch, and a traction belt is provided in the hand-operated electric winch.
[0016] With the above arrangement, the hand-light integrated winch drives the traction belt to pull the boat onto the frame. After the boat is pulled onto the frame, the frame can be driven by the lifting electric walking mechanism to achieve walking, thereby realizing transportation.
[0017] Furthermore, the buffer device includes a buffer body, and there are more than two upper brackets and lower brackets. The upper bracket is fixed on one end of the frame near the opening, and the lower bracket is fixed on both sides of one end of the traction beam near the hinge. The two ends of the buffer body are rotatably connected to the upper bracket and the lower bracket respectively.
[0018] The above arrangement facilitates the synchronous driving of the buffer body to rotate during the process of the front end of the frame rotating and lifting, so that the front end of the frame slowly rotates and lifts under the action of the buffer body, thereby playing a buffering role.
[0019] Furthermore, the spacing between the first and second clamping seat welding plates matches the width of the traction beam.
[0020] The above arrangement facilitates the traction beam to be clamped between the first clamping seat welding plate and the second clamping seat welding plate to achieve locking. BRIEF DESCRIPTION OF THE DRAWINGS
