In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
Please refer to fig. 1 and fig. 3 together, the utility model provides a small, safe and reliable and longer life's pontoon bridge installation mechanism of amplitude of oscillation, this pontoon bridge installation mechanism is including being fixed in the waters bottom and with the fixed pipe 100 and the rigid coupling of waters intercommunication and supporting the movable tube 200 of pontoon bridge 10, the inner chamber and the top that fixed pipe 100 was located to movable tube 200 cover are equipped with fixed pipe 100 top edge complex apron 210, still including locating the rolling device 300 that is used for reducing frictional force between fixed pipe 100 and the movable tube 200, movable tube 200 receives the buoyancy of waters to act on and holds up pontoon bridge 10 and receive the restraint of fixed pipe 100 to prescribe a limit to the swing range of pontoon bridge 10.
The floating bridge installation mechanism of the utility model is implemented by sleeving the movable pipe 200 in the fixed pipe 100 and arranging the rolling device 300 between the fixed pipe 100 and the movable pipe 200, the swinging range of the movable pipe 200 relative to the fixed pipe 100 is smaller, so that the swinging range of the floating bridge 10 installed on the movable pipe 200 is further limited, the swinging range of the floating bridge 10 is smaller and more stable, the vertigo feeling of personnel is eliminated, the risk of the personnel falling into the water area is reduced, and the use safety of the floating bridge 10 is improved; the use of the rolling device 300 reduces the abrasion between the fixed pipe 100 and the movable pipe 200, which is beneficial to prolonging the service life of the fixed pipe 100 and the movable pipe 200, and further reduces the use cost of the floating bridge 10.
The fixed pipe 100 serves to define the position of the movable pipe 200, thereby restricting the movable area of the pontoon 10 for managing the pontoon 10. In one embodiment, the fixed pipe 100 is a mechanically strong metal pipe, such as a corrosion-resistant stainless steel pipe, or may be a prefabricated cement pipe or other mechanically strong pipe. In actual installation, the fixed pipe 100 is completely immersed in the water body of the water area, that is, the top of the fixed pipe 100 is located below the water surface, so that water enters the bottom of the fixed pipe 100 through the gap between the fixed pipe 100 and the movable pipe 200, and the movable pipe 200 is always kept under the buoyancy of the water body. Of course, the bottom of the fixed pipe 100 may be provided with a water leakage hole, so that water can enter the inner cavity of the fixed pipe 100, and the buoyancy of the water body on the movable pipe 200 is ensured.

It should be noted that, for guaranteeing that the buoyancy of the water body to the movable tube 200 is enough to lift the pontoon 10, reduce the load of fixed pipe 100 and movable tube 200, the density of the movable tube 200 of the utility model should be less than the density of the water body, therefore, the movable tube 200 can be made of materials with small density and large mechanical strength such as engineering plastics, and should not select metal materials. The cover plate 210 is adapted to abut against a top edge of the stationary pipe 100 to define a relative position of the movable pipe 200 to the stationary pipe 100 in an axial direction thereof. Preferably, the width of the cap plate 210 is greater than the inner diameter of the fixing tube 100. When the water level in the water area drops to a position where the buoyancy applied to the movable tube 200 is smaller than the gravity, the movable tube 200 rapidly falls in the inner cavity of the fixed tube 100 until the cover plate 210 abuts against the top edge of the fixed tube 100, i.e., the top opening end surface of the fixed tube 100 abuts against the top opening end surface, and the movable tube 200 stops further falling, so that the problem that the movable tube 200 is difficult to take and place when the movable tube 200 completely falls into the fixed tube 100 is solved, and the management difficulty of the floating bridge 10 is reduced.
In one embodiment, the pontoon 10 is mounted on the cover plate 210 at a side thereof remote from the movable pipe 200. Specifically, in the installation of pontoon bridge 10, only need put pontoon bridge 10 at the top of activity pipe 200, make the bottom surface and the apron 210 butt of pontoon bridge 10, only fix a position pontoon bridge 10 through the bolt or predetermine the knot position afterwards, the bolt of deuterogamying consolidates pontoon bridge 10 and the being connected of apron 210, in order to promote the stability that pontoon bridge 10 and apron 210 are connected, therefore, greatly reduced pontoon bridge 10's the dismantlement degree of difficulty, and promoted pontoon bridge 10's maintenance efficiency.
The rolling device 300 is used for filling the gap between the movable pipe 200 and the fixed pipe 100 and reducing the swinging amplitude of the movable pipe 200 in the fixed pipe 100, and the rolling device 300 is also used for converting the sliding friction generated when the movable pipe 200 is in contact with the inner surface of the fixed pipe 100 due to swinging into rolling friction, namely, the friction force between the movable pipe 200 and the fixed pipe 100 is reduced, so that the abrasion of the pipe wall is delayed, the service life of the pipeline is prolonged, and the use and maintenance cost of the floating bridge 10 is reduced. In one embodiment, the rolling device 300 includes at least two balls or rollers 310, and each ball or roller 310 is uniformly arranged along the circumference of the outer surface of the movable tube 200. Through making each ball or gyro wheel 310 evenly set up the circumference at the activity pipe 200 surface, be rolling friction with fixed pipe 100 cooperation position on the activity pipe 200, avoid gathering together when a department because of ball or gyro wheel 310 between activity pipe 200 and fixed pipe 100, ball or gyro wheel 310 push activity pipe 200 to fixed pipe 100 inner wall, and then cause the frictional force increase between activity pipe 200 and the fixed pipe 100, but the scope grow problem of swinging of activity pipe 200, with guarantee to the spacing reliability of activity pipe 200 and pontoon 10.
