Description

Technical Field

[0001] The present invention relates to the technical field of underwater support for water-crossing platforms, and specifically to a buffer device for an underwater support structure of a steel structure water-crossing platform. Background Art

[0002] A water-crossing platform refers to a platform built on the water surface. The base of the water-crossing platform is fixed to the bottom of the water, and the platform is located at the top of the base.

[0003] In the prior art, the support rod of the water-crossing platform is fixed to the bottom of the water. The sleeve at the bottom of the water-crossing platform is sleeved outside the insertion rod to play a limiting role, and the platform floats on the water surface.

[0004] However, since the platform floats on the water surface, when the platform shakes up and down, the platform will move up and down outside the support rod, causing the support rod to shake, affecting the stability of the support rod, and causing the bottom of the support rod to become loose over time. Summary of the Invention

[0005] The purpose of the present invention is to provide a buffer device for an underwater support structure of a steel structure water-crossing platform to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A buffer device for an underwater support structure of a steel structure water-crossing platform, including: a floating plate, on the surface of which through holes are provided;

[0007] A support rod, at the end of which a connecting rod is connected. An inner ring is sleeved outside the connecting rod, an outer ring is arranged outside the inner ring, insertion slots are provided on the surface of the outer ring, an extension block is fixed at the top of the outer ring, and a second screw is screwed on the top of the extension block; and

[0008] A bottom ring, arranged at the top of the support rod.

[0009] Preferably, a sleeve ring is fixed at the bottom of the floating plate. The inside of the sleeve ring is empty and communicates with the through holes. A first screw is screwed on the surface of the sleeve ring. A rubber ring is sleeved outside the sleeve ring. A limiting groove is provided on the inner wall of the rubber ring. After the rubber ring moves, the first screw is inserted into the limiting groove. And a limiting block is fixed inside the sleeve ring. There are multiple groups of limiting blocks, and the multiple groups of limiting blocks are evenly distributed on the inner wall of the sleeve ring.

[0010] Preferably, a connecting rod is fixedly arranged in the middle of the support rod. The diameter of the connecting rod is smaller than that of the support rod. The inner ring can move outside the connecting rod. A card slot is provided on the surface of the support rod, and the cross-section of the card slot is T-shaped.

[0011] Preferably, there are multiple sets of insertion slots on the outer ring surface, and the width of the insertion slots is the same as that of the limiting blocks. The limiting blocks can be inserted into the insertion slots. An extension rod is fixed to the top of the outer ring, and an L-shaped rod is inserted into the top of the extension rod. The L-shaped rod can move up and down on the top of the extension rod. The top of the L-shaped rod can be inserted into the card slot and can slide in the card slot.

[0012] Preferably, a retaining ring is fixed to the bottom of the inner ring. The diameter of the retaining ring is larger than that of the inner ring. The inner ring can move outside the connecting rod, and a ring groove is fixed to the surface of the inner ring. An insertion ring is provided on the inner wall of the outer ring. The diameter of the insertion ring is larger than that of the ring groove. The insertion ring is inserted into the ring groove and can move in the ring groove.

[0013] Preferably, a first spring is fixed to the surface of the inner ring. The other end of the first spring is connected to the inner wall of the outer ring. There are multiple sets of first springs, and the first springs are distributed at the top and bottom of the inner ring.

[0014] Preferably, a holding plate is inserted into the extension block. The holding plate is inclined, and the surface of the holding plate is connected to a second spring. The other end of the second spring is connected to the inner wall of the extension block. The second spring has a pulling force on the holding plate, causing the holding plate to retract into the extension block.

[0015] Preferably, the end of the holding plate is arc-shaped. After the second screw is screwed into the extension block, the end of the second screw abuts against the end of the holding plate, pushing the holding plate out of the inner wall of the extension block. The end of the holding plate abuts against the top of the floating plate.

[0016] Preferably, screw holes are provided on the surface of the outer ring. There are multiple sets of screw holes, and the first screw can be screwed into the screw holes.

[0017] Preferably, the bottom of the support rod is fixed to the bottom of the water, and the floating plate floats on the water surface. There are multiple sets of support rods and floating plates. The multiple support rods are combined together to form a plane, and the support rods are evenly distributed at the bottom of the water.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The support rod of the present invention is inserted into the through hole, so that the sleeve ring is sleeved outside the outer ring, the limit block is inserted into the insertion groove, and the first screw rod is screwed, so that the first screw rod is screwed into the screw hole, and the floating plate is fixed outside the outer ring. Since the floating plate floats on the water surface, when the floating plate is lifted, the L-shaped rod is inserted into the card slot and then rotated, so that the outer ring is stabilized on the top of the connecting rod, which is convenient to fix the floating plate outside the outer ring. And the L-shaped rod can shake in the extension rod. A ring groove is formed inside the outer ring, and an insertion ring is inserted into the ring groove. The insertion ring can shake in the ring groove. When the floating plate shakes, the insertion ring can shake in the ring groove. And the outer ring and the inner ring are connected by a first spring, which plays a buffering role. And by screwing the second screw rod, the end of the second screw rod pushes against the holding plate, and the holding plate pushes against the top of the floating plate to prevent the floating plate from loosening. And the rubber ring moves upward, and the first screw rod is stuck in the limit groove to prevent the first screw rod from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
