Height-adjustable outboard motor hanging rack

Abstract

The invention belongs to the technical field of engineering pontoons and particularly relates to an outboard motor hanging rack. According to the technical scheme, the height-adjustable outboard motor hanging rack comprises a hand pump, a platform, upper guide rails, lower guide rails, an oil cylinder driven by the hand pump, an upper roller assembly, a lower roller assembly and an oil cylinder mounting seat; when the water level gets lower, the hand pump is operated, a piston rod of the oil cylinder is enabled to jack up an outboard motor to ascend to appropriate height; when the water level gets higher, the hand pump is reversely operated, the piston rod of the oil cylinder is enabled to descend, the outboard motor downwards slides to appropriate height along the upper guide rails and the lower guide rails under the action of gravity, and a propeller is enabled to keep appropriate draft. The height-adjustable outboard motor hanging rack can be used for adjusting the draft of the propeller of the outboard motor conveniently, thereby adapting to the water depth of a river channel and also adapting to larger draft change in loading and unloading processes of the pontoons.

Description

technical field [0001] The invention belongs to the technical field of engineering buoyancy tanks, in particular to a hanger for an outboard engine. Background technique [0002] When the engineering buoy needs to be equipped with power, the outboard motor with high system integration, simple installation process and low installation technical requirements is usually used. The outboard motor is installed on the outboard motor hanger of the engineering buoyancy tank. The existing buoyant tank outboard motor hanger is in the form of a fixed type, which is welded together with the buoyancy tank and cannot be disassembled. This method has the following disadvantages: [0003] 1. The fixed outboard motor hanger, as a part of the engineering buoy, is directly welded on the buoy and cannot be disassembled, so the outboard can only be hung on the side of the hanger mechanism of the engineering buoy, so the power of the buoy The direction of propulsion is just fixed as a side of the...

AI Technical Summary

Problems solved by technology

[0003] 1. The fixed outboard motor hanger, as a part of the engineering buoy, is directly welded on the buoy and cannot be disassembled, so the outboard can only be hung on the side of the hanger mechanism of the engineering buoy, so the power of the buoy The direction of propulsion is fixed to one side of the pontoon. When the pontoon needs power in different propulsion directions, it is necessary to redesign and manufacture the pontoon, resulting in a waste of resources.

[0004] 2. When the water level of the river changes and encounters a shoal, the outboard motor cannot dodge in time, then the propeller of the outboard motor will touch the river bed, causing damage to the propeller and loss of propulsion ability

[0005] 3. The draught of the engineering buoyancy tank varies greatly from empty load to full load. If the outboard motor hanger mechanism is set according to the empty load, then, in order to ensure that the outboard motor propeller has sufficient draft, the hanger mechanism needs to be set at the bottom of the buoyancy tank. Lower position, in this way, when the pontoon is loaded, the pontoon sinks, the pylon mechanism sinks accordingly, and the draft of the propeller of the outboard motor increases. When the pylon sinks a lot, the engine of the outboard motor will Submerged in the water, the outboard motor cannot work; if the installation height of the outboard motor is set according to the full load, in order to ensure that the engine of the outboard motor is always above the water surface, the hanger mechanism needs to be set at a higher position in the pontoon. After unloading, the pontoon floats up, the draft becomes shallower, and the outboard motor rises together with it. When the outboard motor rises too high, the draft of the propeller will be very shallow, or even lifted out of the water surface, resulting in a reduction in the propulsion efficiency of the propeller or loss of propulsion

[0006] 4. Because the fixed hanger is welded on the floating tank, the floating tank with the fixed hanger cannot be used in common with the ordinary floating tank, and when it is combined with the standard floating tank to assemble the water platform, it can only be assembled on the outermost side, so that affected its scope of use

[0007] 5. Sometimes the hanger mechanism and the floating tank are connected in a hinged way, and they are put down when in use. However, when the water level of the river channel becomes shallow or the carrying capacity of the floating tank changes, effective measures cannot be taken in time. rise or fall, thereby losing its propulsion function
