Bridge device for facilitating the deployment of a wakeboard

Abstract

The present invention provides a bridging device facilitating the deployment of a water ski board, belonging to the technical field of water ski boards. The bridging device facilitating the deployment of a water ski board includes an amphibious vehicle assembly and a bridging assembly. The amphibious vehicle assembly includes an amphibious vehicle and a first mounting plate. The bridging assembly includes a base arm, a first oil cylinder, a second oil cylinder, a swing arm, a leg oil cylinder, a fixed arm, a bridge and a third oil cylinder. The first oil cylinder drives the swing arm to deflect around the first mounting plate, and drives the water ski board at one end close to the base arm to rise through the deflection, expanding the deployment space of the water ski board and facilitating the deployment of the water ski board. This effectively improves the problem that the water ski board is not easily deployed after a bridging structure is installed on the upper end of the amphibious vehicle. During land travel, raising the water ski board at one end close to the base arm can also improve the driver's line of sight and facilitate the driver to observe the road surface conditions. When encountering a road surface with a height limit, the base arm is lowered to reduce the height of the device and facilitate passing through the height-limited road surface.

Description

Technical Field

[0001] The present invention relates to the field of water skis, and more particularly to a bridging device that facilitates the deployment of water skis. Background Art

[0002] An amphibious vehicle has excellent water and land passage performance and can cross rivers, lakes and seas without being restricted by bridges or ships. Therefore, it has been widely regarded and applied in transportation. The water skis on an amphibious vehicle are composed of upper and lower parts. When driving on land, the water skis are folded and retracted on the vehicle body surface. The upper part is folded and retracted in the upper front part of the amphibious vehicle, and the lower part is retracted in the lower front part of the amphibious vehicle. When sailing on water, the water skis are deployed forward at a certain angle to the water surface to reduce the sailing resistance. At present, during the deployment and retraction of the folding water skis, a certain swinging space is required. After installing a bridging structure on the upper end of the amphibious vehicle, the folding water skis are prone to interference with the bridging structure during deployment and retraction, thereby affecting the smooth deployment of the water skis.

[0003] How to invent a bridging device that facilitates the deployment of water skis to improve these problems has become an urgent problem for those skilled in the art to solve. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a bridging device that facilitates the deployment of water skis, aiming to improve the problem that the water skis are not easily deployed after installing a bridging structure on the upper end of the amphibious vehicle.

[0046] Specifically, the working principle of the bridging device facilitating the deployment of the hydrofoil: During use, the first oil cylinder 220 drives the swing arm 240 to deflect around the first mounting plate 130, driving the end of the base arm 210 close to the hydrofoil 120 to rise, expanding the deployment space of the hydrofoil 120, facilitating the deployment of the hydrofoil 120, and effectively improving the problem that the hydrofoil is not easy to deploy after a bridging structure is installed on the upper end of the amphibious vehicle. During land travel, raising the end of the base arm 210 close to the hydrofoil 120 can also improve the driver's line of sight and facilitate the driver to observe the road conditions. When encountering a road with a height limit, lower the base arm 210 to reduce the height of the device and facilitate passing through the height-limited road.

[0047] When bridge erection is required, the second oil cylinder 230 is pushed out. The second oil cylinder 230 drives the swing arm 240 to deflect. The fixed arm 260 and the bridge frame 270 move along with the swing arm 240. When the swing arm 240 deflects to be perpendicular to the ground, the outrigger oil cylinder 250 is pushed out until the outrigger oil cylinder 250 supports the ground, improving the force on the swing arm 240 and the second oil cylinder 230. The third oil cylinder 280 is pushed out. The third oil cylinder 280 drives the fixed arm 260 to deflect, and the bridge frame 270 deflects along with the fixed arm 260 until one end of the bridge frame 270 falls to the ground on the opposite side of the riverbed. The connection between the fixed arm 260 and the bridge frame 270 is removed, and the bridge frame 270 falls, achieving the purpose of bridge erection. Both ends of the bridge frame 270 are provided with inclined planes to facilitate vehicles and pedestrians passing through the bridge frame 270.
