Through setting up a plurality of sliders and corresponding first spout 220 or second spout 110 of slider, increased the cooperation area of activity stake 200 with spud pile 100, improved the stability of the two connection, alleviateed the volume of rocking when activity stake 200 slides for spud pile 100, guaranteed the reliability that pontoon 20 goes up and down. When the sliding block mechanism 300 is fixedly installed on the inner wall of the fixed pile 100 and the outer wall of the movable pile 200, the sliding block mechanism 300 includes a first sliding block installed on the top of the inner wall of the fixed pile 100 and a second sliding block installed on the bottom of the outer wall of the movable pile 200, so as to further increase the contact area between the movable pile 200 and the fixed pile 100 and improve the stability and reliability of relative sliding between the movable pile 200 and the fixed pile 100. It should be noted that, when the first slider and the second slider are respectively disposed on the fixed pile 100 and the movable pile 200, the first slider and the second slider are disposed at an interval, the movable pile 200 is provided with a first sliding chute 220 engaged with the first slider, and the fixed pile 100 is provided with a second sliding chute 110 engaged with the second slider, so as to improve the stability of the engagement between the fixed pile 100 and the movable pile 200.
Referring to fig. 1 again, in one embodiment, a pile cover 400 is disposed on the top of the movable pile 200, the cross-sectional area of the pile cover 400 is greater than that of the fixed pile 100, and the pile cover 400 is welded or screwed to the movable pile 200. Through setting up stake lid 400, can provide the installation position of pontoon 20 on the one hand, on the other hand, through setting up stake lid 400, when not installing pontoon 20, can avoid crossing low excessively because of the waters water level, the drop distance of activity stake 200 is too big, and then causes activity stake 200 to fall into spud pile 100 completely for pontoon 20 installs the emergence of difficulty problem under low water level, thereby guarantees that flexible stake has good flexible effect.
According to the telescopic pile 10 for fixing the floating bridge, the sliding block mechanism 300 is arranged between the fixed pile 100 and the movable pile 200, when the water level of a water area changes, the movable pile 200 is lifted along with the change of the water level, so that the floating bridge 20 is always positioned on the water surface, the buoyancy of the water body can support the floating bridge 20, the load of the fixed pile 100 and the movable pile 200 is reduced, and the service life of the telescopic pile and the floating bridge 20 can be prolonged; the sliding block mechanism 300 can reduce the friction force between the inner wall of the fixed pile 100 and the outer wall of the movable pile 200, and ensure the reliability of the sliding of the movable pile 200 relative to the fixed pile 100; in addition, through the arrangement of the first sliding groove 220 or the second sliding groove 110 matched with the sliding block mechanism 300, the circumferential movement of the movable pile 200 relative to the fixed pile 100 is limited, and the movable pile 200 can be prevented from driving the floating bridge 20 to rotate or swing relative to the fixed pile 100, so that the positioning reliability of the floating bridge 20 is ensured, and the safety of personnel standing on the floating bridge 20 is improved.
