Description
The technical field is as follows:
the utility model belongs to the technical field of fender processing manufacturing, concretely relates to roll formula fender, under the boats and ships berth state, the impact of boats and ships can rotate the fender, reduces boats and ships to the impact force of fender, and when boats and ships floated from top to bottom along with the surge, can reduce the friction between boats and ships and the fender, effectively protected the hull outer wall.
Background art:
the fender is also called as the fender of a ship, is an elastic buffer device used at the edge of a wharf or a ship, is made of wood and rubber, is mainly used for slowing down the impact force between the ship and the wharf or between the ships in the process of docking or mooring, and reducing or eliminating the damage to the ship and the wharf; chinese patent 201710411577.5 discloses a rubber fender device of a full-rotation tugboat, which structurally comprises a first supporting roller, a connecting gasket, a base, a connecting shaft, a first fixing ring, a second fixing ring, a first support, a fixing screw port, a second support, a second supporting roller and a third support, wherein the upper part and the lower part of the first supporting roller are respectively provided with the connecting gasket; chinese patent 201820640275.5 discloses a mobile rolling fender, which comprises a circular rolling fender, a fender bracket and a telescopic oil cylinder, wherein the fender bracket is of a triangle-like structure, one corner of the fender bracket is provided with a fixed rubber roller shaft, two circular rolling fenders are fixed on the fixed rubber roller shaft, the second corner of the fender bracket is provided with a positioning shaft, the fender bracket rotates 90 degrees around the positioning shaft to reach the working position for protecting a ship, the third corner of the fender bracket is provided with a positioning lug plate, a fixed pin shaft is inserted into the positioning lug plate, the telescopic oil cylinder is arranged below the fender bracket, a hydraulic oil cylinder is adopted to replace manpower, the docking operation time is shortened, and the work efficiency is improved; chinese patent 201820999472.6 discloses a vertical rotary fender and a vehicle roll-on-roll-off ship, wherein the vertical rotary fender comprises a connecting frame with at least one side surface formed to be open and the inside formed to be a hollow structure, and a plurality of rolling elements partially arranged in the hollow structure, the bottom of the connecting frame is also connected with an arc-shaped guide plate, the connecting frame is arranged to be hollow, and the rolling elements partially arranged in the hollow structure are arranged in the hollow structure, so that the friction between a ship body and a gate wall can be effectively protected during gate passing, the ship body can run lightly in the gate, and meanwhile, the arc-shaped guide plate is formed at the bottom of the connecting frame, so that a small ship is effectively prevented from being clamped at the bottom end during gate passing; in the prior art and in the patent products, the rolling fender can reduce the impact of a ship on a wharf when the ship is in a parking state, but the friction force generated when the ship floats up and down along with surge is large, so that the outer wall of the ship is easily damaged, and the service life of the ship is influenced; therefore, the rolling type fender is researched and designed, the fender can be rotated by the impact force of a ship in a ship parking state, the impact force of the ship on the fender is reduced, when the ship floats up and down along with surge, the friction between the ship and the fender can be reduced, the outer wall of a ship body is effectively protected, and the rolling type fender has good use value and popularization prospect.
The invention content is as follows:
the utility model aims to overcome the not enough and defect that prior art exists, seek to design and provide a structure scientific and reasonable, roll formula fender that convenience safe in utilization can be under the boats and ships berth state, and the impact force through boats and ships rotates the fender, reduces boats and ships to the impact force of fender, and when boats and ships floated from top to bottom along with the surge, can reduce the friction between boats and ships and the fender, effectively protects the hull outer wall.
In order to achieve the above object, the main structure of the present invention comprises: the fender bracket, the rolling body, the connecting shaft and the bearing; the fender support is composed of a bottom plate, support rods and reinforcing plates, two groups of parallel support rods are arranged on the square bottom plate, the bottom ends of the two groups of support rods are vertically and fixedly connected with the bottom plate, the reinforcing plates are arranged between the two groups of support rods and the bottom plate, and the reinforcing plates are vertically and fixedly connected with the bottom plate and the support rods; a rolling body is separately arranged between the two groups of support rods, and a rubber layer, an EVA foaming material layer and a polyurea spraying layer are sequentially arranged on the rolling body from inside to outside; a connecting shaft is fixedly arranged in the rolling body, the connecting shaft penetrates through the rolling body, two ends of the connecting shaft respectively extend outwards into the two groups of supporting rods, and the connecting shaft and the rolling body are on the same horizontal central axis; and bearings are arranged between two ends of the connecting shaft and the two groups of supporting rods, the inner walls of the bearings are fixedly connected with the connecting shaft, and the outer walls of the bearings are fixedly connected with the supporting rods.
Compared with the prior art, the utility model, its overall structure has changed prior art's shortcoming, and its structure scientific and reasonable can rotate the fender through the impact of boats and ships under the boats and ships berth state, reduces boats and ships and to the impact force of fender, and when boats and ships floated from top to bottom along with the surge, can reduce the friction between boats and ships and the fender, effectively protects the hull outer wall, and its processing technology is simple, and the cost of manufacture is low, long service life, and application environment is friendly.
