Description

A floating platform equipped with a conveyor}

The present invention relates to a floating pier combined with a conveyor, and more specifically, to a floating bridge that improves the convenience of cargo transportation in an aging fishing village by combining a cargo transport conveyor on the side of the base frame of the bridge.

A floating bridge is a facility that combines a pontoon bridge floating on the water surface of a lake or beach and a footbridge connecting a steep coast. It is usually installed between the steep land and the water's edge to facilitate the movement of people and cargo. am. A pontoon bridge floats on the water surface by combining multiple buoyant bodies at the bottom of the square-shaped upper plate. Piles or pillars are installed under the water to tie the pontoon bridge and limit the movement of the pontoon bridge. The side of the pontoon bridge is used when a ship docks. A band-shaped buffer member or multiple tires are installed to absorb shock, and a number of hanging posts for tying ropes are installed around the top of the pontoon bridge so that docking vessels can be tied with ropes and docked. .

Because floating piers installed on the coast can be affected by rain, wind and waves, recent floating bridges are being developed one after another that can flexibly respond to changes in water level and withstand external shocks such as currents and waves. Republic of Korea Patent No. 10-0984 766 and Registered Patent No. 10-1254018 are examples of technologies related to floating piers that provide this function. Registered Patent No. 10-0984766 installs a ball on the lower part of the top of the bridge and combines a lower plate with a hemispherical groove to accommodate the ball on the revetment to comply with the up and down movement and left and right twist of the bridge. To complement the connection, the bridge and pontoon bridge are connected in a chain to prevent the bridge from breaking away.

Registered Patent No. 10-1254018 covers a pier floating in the sea, a hinge member installed on land, a footbridge connected to the hinge member, and a hanging part that is located on land and allows the upper part of one side of the footbridge to be rotatably hung. A floating pier was developed that is located on land and has a lifting part that connects the other side of the bridge to the other side of the bridge and moves the bridge to the hanging part, and has the function of lifting the bridge in bad weather or other times of need.

Conventional technologies for such floating bridges have greatly contributed to reducing the effects of currents and waves during bad weather, but in order to raise and lower heavy cargo on a steeply sloping bridge when the sea level is lowered, the cargo must still be carried or carried manually by manpower. There is a problem with doing this.

Republic of Korea Patent No. 10-0984 766 Republic of Korea Patent No. 10-1254018

In order to improve the above problems, the present invention attaches a conveyor belt to a footbridge to facilitate the transportation of cargo in fishing villages, prevents cargo from slipping even if the slope of the footbridge is high, minimizes vibration of the conveyor, and adjusts the height and lowering of the water surface. We aim to provide a floating bridge that can alleviate the shock caused by the horizontal movement of the floating bridge due to wind, etc., and allows the conveyor to be used for a long time by easily adjusting the tension of the belt.

In order to perform the above task, the present invention includes a pontoon bridge (50) installed on the water surface of the coast; A bridge fixing plate (70) installed on coastal land; A pair of side beams 120 forming the side of the bridge 100 installed between the pontoon bridge and the bridge fixing plate, an upper crossbar 130 and a lower crossbar 150 horizontally connected to the pair of side beams 120, a plurality of A base frame (110) consisting of one or more internal beams coupled in parallel between the middle crossbar (170) and the pair of side beams (120); A handrail (200) coupled to the upper part of the side beam (120); A driving roller 300 coupled to the side beam 120 on one side and the upper part of the inner beam; A lower roller 320 coupled to the lower part of the side beam 120 and the inner beam to which the driving roller 300 is coupled; A driving motor 350 installed on the side beam 120 on one side; Power transmission means 370 coupled to the shaft of the drive roller 300 and the shaft of the drive motor 350 to transmit power to the drive motor 350; A stainless steel plate 400 coupled to the upper part of the middle crosspiece 170 between the driving roller 300 and the lower roller 320; A conveyor belt 410 in contact with the upper part of the stainless steel plate and coupled to the outside of the driving roller 300 and the lower roller 320; A support roller 450 coupled between the side beam 120 and the inner beam 180 to support the lower part of the conveyor belt 410; A fixing plate hinge member 600 coupled to the upper part of the bridge fixing plate; An upper hinge member (650) coupled to the upper crossbar (130); And a control box 900 installed on the handrail 200 to control the operation of the drive motor 350.

The present invention, constructed as described above, improves the convenience of transporting cargo in fishing villages by attaching a conveyor to a footbridge, prevents cargo from slipping when caught on a non-slip bar even when the slope of the footbridge is high, and minimizes vibration of the conveyor because the belt rotates on a stainless steel plate. The shock caused by the up-down and horizontal movement of the pontoon bridge is alleviated by the bottom roller combined with the spring and the springs installed on both sides of the bottom roller. The tension of the belt can be easily adjusted, allowing the conveyor to be used for a long time, and the motor and power transmission The rain and wind are blocked by the waterproof cover attached to the part, which reduces the maintenance burden and extends the life of the bridge.
