Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be known from fig. 1 to 4, the utility model discloses a suit is at cyclic annular gasbag 1 on the pier, the up end of cyclic annular gasbag 1 is equipped with an annular plate 2, the up end circumference equipartition of annular plate 2 has a plurality of vertical support columns 3, it has a plurality of openings fixing device outwards to follow its axial equipartition on every support column 3, every fixing device includes two upper and lower interval arrangement and opening arc 4 outwards, be equipped with tire 5 between two arc 4, arc 4 has two rows of rollers 6 along its radian direction equipartition, tire 5's outer fringe face is arranged in to one row of roller 6, the inboard of circle in tire 5 is arranged in to another row of roller 6, two rows of rollers 6 can be fixed tire 5 in two corresponding arc 4, and can make tire 5 at the fixing device internal rotation.

In order to realize the installation of annular gasbag and annular plate 2, annular gasbag 1 is formed by two semi-annular gasbags combinations, and two semi-annular gasbags lock forms an annular gasbag 1 on the pier, and annular plate 2 has two semi-annular plates 2 combinations to form, and two semi-annular plates 2 are through fastening pin combination into an annular plate 2.

In order to fix the supporting column 3, the upper end of the annular plate 2 is coaxially provided with a circular ring 7, the circular ring 7 is composed of two semi-annular rods, the two semi-annular rods are combined into a circular ring 7, and the upper end of the upright column is fixed on the outer circular surface of the circular ring 7.

In order to realize the installation of two sets of rollers 6, the upper and lower both ends that are close to a set of roller 6 in the outside on every fixing device of group all rotate and connect on two arcs 4 that correspond, a set of roller 6 that is close to the inboard includes a round pin axle 8 of demountable installation on two arcs 4, and round pin axle 8 can not rotate, and round pin axle 8 arranges the upper and lower both ends individual rotation of two arcs 4 internal parts in and is connected with a gyro wheel 9, and gyro wheel 9 contacts with the inner edge face of tire 5.

In order to realize the auxiliary reset after the tire 5 is extruded, a telescopic rod 10 with an outward extending end is arranged at the part, arranged in the tire 5, of the pin shaft 8, a pressure spring 11 is sleeved outside the telescopic rod 10, one end of the pressure spring 11 is fixed on the pin shaft 8, and the other end of the pressure spring is fixed at the extending end part of the telescopic rod 10.

The utility model discloses a concrete working process is: when the device is used, the device is combined and fixed on the outer side of a pier, wherein intervals uniformly exist among the annular air bags 1, the annular plate 2, the circular ring 7 and the pier, the plurality of tires 5 and the supporting devices thereof are arranged on the water surface in a floating mode under the action of buoyancy after the annular air bags 1 are inflated, the tires are easily collided by the pier, the annular air bags 1 can drive all the parts mounted on the annular air bags to float up and down according to the depth of the water level, and the pier is guaranteed to be easily protected by the parts of the device all the time.

When the hull is close to the pier and when brushing on the buffer device limit, with hull contact back hull removal can drive 5 rotations of tire and supplementary hull and leave the pier and play the effect of buffering, when the hull striking on the pier, tire 5 realizes the buffer protection to the pier through warping, leaves the back when the hull, under tire 5's self reset action with the telescopic link 10 and the pressure spring 11 the reset action under supplementary tire 5 resets to realize that this device is sustainable for providing buffer protection for the pier.

The significant benefits of the present device: this device replaces the gasbag through junked tire 5 and provides the buffer protection for the pier, has practiced thrift the resource on the one hand and has recycled the wastes material, and on the other hand when the hull draws the time from the tire 5 outside 5 autorotations can effectual supplementary hull to leave, prevents that the hull from destroying buffer, when the hull directly collides to the pier, tire 5 warp and provides the buffer support for the pier, and the effectual pier that prevents is destroyed, but this device low in manufacturing cost and repetitious used repeatedly.
