[0002] Gangway refers to a movable ladder installed on both sides of a ship for passengers to get on and off the ship, made of wood or metal. The gangway device consists of a gangway and its retracting and releasing mechanism, which is generally installed above the bulkhead or freeboard deck, in the passageway on the side that is not closed by the outer plate. When in use, the gangway is moved out of the ship using the retracting and releasing mechanism, and is placed obliquely beside the ship close to the hull plate for people to get on and off. When the ship is sailing, the gangway should be folded up and fastened to the side of the deck. When processing the steps of the gangway, the raw materials need to be cut and polished to make them of the same size, and then assembled and used with the ladder frame.

[0003] When the existing cutting device is in use, the staff pushes the raw materials under the cutter and cuts them by manually pushing the raw materials and the cutter. Because the raw materials are generally large plates, they are too large and heavy, and the operation is difficult. At the same time, relying on manual pushing poses a safety hazard.

[0014] Compared with the prior art, the invention has the following beneficial effects: the gangway step cutting and grinding machine is

[0015] (1) In order to solve the problem that in the existing cutting device, when in use, the staff pushes the raw material to the bottom of the cutter, and manually pushes the raw material and the cutter for cutting. Because the raw material is generally a large plate, it is too large and heavy, and the operation is difficult. At the same time, it is safe to push it manually. In this application, the first electric hydraulic cylinder drives the electric linear guide rail to move downward, so that the electromagnetic seat is connected to the upper end of one side of the raw material plate, and then the electric linear guide rail drives the electromagnetic seat and the raw material plate to move and load on the moving roller, so that there is no need for manual pushing of the material.

[0016] (2) In order to solve the problem that the existing cutting device cannot grind the raw material in the same machine body after cutting, and needs to be moved to the grinder for processing, which makes the processing efficiency low and increases the manpower output, the present application uses an electric telescopic rod to push the lifting base and the supporting frame upward, so that the electric longitudinal guide rail drives the cutting machine body to move to cut the raw material plate longitudinally, and at the same time, the grinding sheet arranged on the outside of the cutting tool grinds the cutting position, and the two sides of the raw material plate are grinded by the grinding assembly, thereby improving the processing efficiency and reducing the manpower output;

[0017] (3) In order to solve the problem that the existing devices fail to cool down and collect the heat and dust generated by cutting and grinding after the cutting and grinding are completed, resulting in debris often remaining on the surface of the cut plate. If the debris and dust are not cleaned up in time, it will interfere with the grinding effect.
