Description

Technical Field

[0001] The utility model belongs to the technical field of water propulsion, and in particular relates to a semi-hanging amphibious rescue buoy. Background Art

[0002] At present, most of the powered pontoons are composed of river boats, shore boats, boat vehicles and auxiliary equipment. Although they have achieved amphibious functions, they cannot achieve the ability to maneuver and deliver to overcome water obstacles, quickly change the function and purpose of the vehicle, and the ability to transform.

[0003] The existing power pontoons and water propulsion devices have weak functional integration and correlation. The buoyancy reserve function and the water power function are not effectively integrated. It is impossible to achieve modular rapid replacement of amphibious operations. It is separated from the main body and cannot achieve autonomous water operation functions. The purchase and use costs are high, maintenance is difficult, and the carrying capacity is limited.

[0012] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below.

[0013] The utility model provides a semi-hanging amphibious rescue buoy, comprising a vehicle body 1, a hydraulic tailgate 2, a water propeller 3, a running wheel 4, a shock-absorbing leaf spring 5, an engine 6, a liftable front wheel 7, a cockpit 8, a gooseneck 9, a hydraulic pump station 10, a vehicle battery 11, a seat ring 12 and a steering system 13;

[0014] The outer surface of the vehicle body 1 is welded with aluminum alloy. In consideration of weight reduction, the main cross beam, longitudinal beam and bearing ribs of the internal skeleton of the vehicle body are welded with I-beams and channel steels, and are connected with bolts through the main cross beam of the vehicle body 1 and the axle of the semi-trailer.

[0015] The hydraulic tailgate 2 is arranged at the rear of the vehicle and connected to the vehicle body 1 through a hydraulic cylinder for rapid loading and unloading of personnel, vehicles and materials and equipment.

[0016] The water thruster 3 is arranged on the left and right sides of the rear of the vehicle, fixed to the vehicle body connecting plate by bolts, and driven by a hydraulic motor.

[0017] Travel wheels 4 are arranged at the rear of the vehicle, placed in parallel, and connected to the axle of the semi-trailer by bolts.

[0018] The shock-absorbing leaf spring 5 is installed between the vehicle bridge and the bottom of the vehicle body 1. When the semi-trailer amphibious rescue pontoon is traveling on land, it encounters a road with poor road conditions and plays a buffering and energy-absorbing role. The leaf spring uses a general semi-trailer spring.

[0019] The engine 6 is arranged on the right side of the vehicle bow and is fixed to the attachment seat reserved on the vehicle body 1.

[0020] The liftable front wheels 7 are arranged on the left and right sides of the vehicle bow to reduce the resistance of the vehicle bow in underwater propulsion. They have a folding function, which is realized by a hydraulic cylinder. Longitudinal tracks are designed on the left and right sides of the wheel hub. When the cylinder piston rod is fully extended, the front wheels are unfolded and on the same horizontal line as the rear wheels for land driving. When the cylinder piston rod is fully retracted, the wheels are hidden to the side of the vehicle body, which is convenient for water driving.

[0021] The cockpit 8 is arranged at the left part of the bow of the vehicle and is fixed with the pre-buried attachment of the vehicle hull 1. It is composed of a frame, an aluminum alloy shell, a window glass, and a wiper spray system.

[0022] The gooseneck 9 - the towing pin at the front end is connected to the towing saddle on the towing vehicle, and the rear end is connected to the vehicle hull 1 through a pin shaft and a hydraulic cylinder. It has a folding function, which is achieved by the hydraulic cylinder. After the cylinder piston rod is retracted, the gooseneck 9 is retracted into the hull 1 and hidden, which is convenient for driving in water. After the cylinder piston rod is extended, the gooseneck 9 is unfolded to the land transportation state and connected to the towing vehicle.

[0023] The hydraulic pump station 10 is arranged on the right side of the vehicle bow and fixed to the attachment seat reserved on the vehicle hull 1 to provide a power oil source for the water propeller 3, the liftable front wheel 7 and the gooseneck 9.

[0024] The vehicle battery 11 is arranged in front of the engine 6 and fixed to the vehicle body by standard parts such as bolts for power supply.

[0025] The seat ring 12 is arranged in the middle of the cabin of the vehicle hull 1 and is fixed to the main cross beam and the longitudinal beam by bolts and other standard parts.

[0026] Steering system 13 - The hydraulic pump provides power for this subsystem. Through the switching of the two-position four-way valve, the steering decoupling cylinder realizes the direction switching, further drives the mechanical structure, completes the connection or disconnection of the steering column and the power steering mechanism, and thus realizes the steering switching in two different situations of land and water.

[0027] Directions:

[0028] Start the engine 6, operate the control handle in the cab 8 to switch the electromagnetic reversing valve of the hydraulic pump station 10 to control the hydraulic cylinder of the gooseneck 9 to extend to connect with the rotary base of the tractor. Figure 3 , realizing the road transportation function of the semi-hook amphibious rescue pontoon.

[0029] On land, the tractor is transported to the shore, and then the semi-hook amphibious rescue pontoon is pushed into the water by reversing. The engine 6 is started, and the control handle in the cockpit 8 is operated to switch the electromagnetic reversing valve of the hydraulic pump station 10 to control the hydraulic cylinder of the gooseneck 9 to retract and separate from the slewing base of the tractor. The clutch handle in the cockpit is operated to engage the transmission shaft with the propeller to realize the water driving operation of the semi-hook amphibious rescue pontoon. The driving speed is controlled by stepping on the accelerator, and the driving direction of the semi-hook amphibious rescue pontoon is realized by operating the water propeller 7 to rotate the handle direction.

[0030] The vehicle hull 1 is a key innovation of the utility model. It adopts the basic line of the round-bilged single-body high-speed boat to achieve a low flow resistance body shape design that integrates vehicle and boat, ensuring the high-speed driving capability and high endurance of the semi-hook amphibious rescue pontoon on the water surface, and is an important innovation in the research of vehicle integration.

[0031] The lightweight body structure adopts lightweight materials such as aluminum alloy and automotive composite materials. Through the optimization design of multiple materials, the body is mainly made of aluminum alloy, and the cab is composed of aluminum alloy and lightweight composite materials. It has a strong and tough synergistic advantage and achieves performance indicators such as high strength / stiffness / high modal frequency under lightweight.

[0032] The water propulsion device 3 is stored in the groove at the rear of the vehicle to avoid the turbulence of the vehicle body and improve the propulsion efficiency.

[0033] The seat ring 12 module can be disassembled and replaced in one piece.

[0034] The utility model newly adds a set of power sources, so that the whole vehicle can be operated normally on water when it is separated from the tractor.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
