Description

Amphibious Vessel Crawler Traveling Mechanism

technical field

The utility model relates to a walking mechanism, in particular to a crawler-type walking mechanism used on an amphibious ship, and belongs to the technical field of amphibious ships.

Background technique

China has a coastline of more than 20,000 kilometers, and its offshore marine resources have not been fully developed. Restricted by tides and coastal topography, offshore marine resources cannot be developed more efficiently. For example, in the coastal aquaculture industry and coastal wind power industry, the operation time can only be completed within a limited specified time, and amphibious ships can effectively avoid these problems;

However, when conventional amphibious boats walk on land, they all adopt a wheeled structure. Due to the heavy weight of the hull itself, when it walks on muddy roads, beaches, tidal flats and other places, the wheels are prone to collapse and cannot walk; at the same time, When it walks on a relatively rough road, when it encounters a high obstacle, or when the road surface has too much ups and downs, the wheeled structure is often unable to climb forward, thus affecting its passing performance.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide a crawler type walking mechanism for amphibious ships with good passability.

A crawler-type walking mechanism for an amphibious ship, the mechanism includes at least one driving wheel driven by an oil cylinder, and at least one driven wheel, the driving wheel and the driven wheel are covered with crawlers, and a lifting mechanism is fixed on the amphibious On the hull of the ship, and the lifting mechanism is connected with the driving wheel or the driven wheel.

The utility model relates to a crawler-type walking mechanism for an amphibious ship. The lifting mechanism includes a lifting oil cylinder, the oil cylinder seat of the lifting oil cylinder is fixed on the hull of the amphibious ship, and a bearing seat is connected to the piston rod of the lifting oil cylinder. A lifting roller is installed on the wheel surface of the driving wheel or the driven wheel, the lifting roller is located on the central axis of the driving wheel or the driven wheel, and the lifting roller is inserted into the bearing seat of the piston rod of the lifting cylinder.

The utility model relates to a crawler-type walking mechanism for amphibious ships. There are two lifting oil cylinders, and a bearing seat is arranged on the piston rod of each lifting oil cylinder. Lifting rollers inserted into the bearing housings are installed.

The purpose of this utility model is achieved in that:

Compared with the prior art, the beneficial effects of the utility model are:

The utility model adopts a crawler-type structure, which greatly increases the force-bearing area and reduces the pressure on the road surface through the contact of the crawler belt with the road surface, so that the hull can walk on soft roads such as tidal flats and sandy beaches; The driving wheel or the driven wheel is lifted, thereby realizing the climbing function, enabling it to walk on a site with large undulations on the road surface, and increasing its passing performance.

Detailed ways

Referring to Figures 1 to 3, the utility model relates to a crawler-type traveling mechanism for amphibious ships, the mechanism includes at least one driving wheel 1 driven by an oil cylinder, and at least one driven wheel 2, the driving wheel 1 and the driven wheel The driving wheel 2 is covered with crawlers 3, and a lifting mechanism 4 is fixed on the hull of the amphibious ship, and the lifting mechanism 4 is connected with the driving wheel 1 or the driven wheel 2;

Specifically, the lifting mechanism 4 includes a lifting cylinder, the cylinder seat of which is fixed on the hull of the amphibious ship, the piston rod of the lifting cylinder is connected with a bearing seat, and the driving wheel 1 or the driven wheel A lifting roller is installed on the wheel surface of 2, and the lifting roller is located on the central axis of the driving wheel 1 or the driven wheel 2, and the lifting roller is interspersed in the bearing seat of the piston rod of the lifting cylinder; so that when the lifting cylinder pulls the driving wheel 1 or When the driven wheel 2 is lifted, it does not affect the normal rotation of the driving wheel 1 or the driven wheel 2;

Preferably, the above-mentioned lifting oil cylinders are provided with two sets, and the piston rod of each lifting oil cylinder is provided with a bearing seat. At this time, the wheel surfaces on both sides of the driving wheel 1 or the driven wheel 2 are equipped with a lifting cylinder inserted into the bearing seat. Roller, when there are two lifting cylinders, the lifting and walking are more stable;

Referring to Fig. 3, when an obstacle is encountered while walking, the driving wheel 1 or the driven wheel 2 is lifted by the lifting mechanism 4, so that the walking mechanism of the utility model can easily climb over the obstacle.

In addition: it should be noted that the above specific implementation is only an optimization solution of this patent, and any changes or improvements made by those skilled in the art based on the above ideas are within the scope of protection of this patent.
