Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a special bridge connection device for water surface. Background Art

[0002] When supplying power to the center of the water surface, the bridge is laid on the floating ship. When the water surface fluctuates, the floating ship and the bridge will fluctuate accordingly. Existing bridge connectors are rigidly connected. Excessive fluctuations or large fluctuations can easily damage the bridge, thereby causing cable damage. CN 221227055 U discloses a bridge connector that can be bent at any angle. Although it can rotate in a direction perpendicular to the bridge surface, it cannot rotate at any time once the angle is fixed, and cannot be used for special bridges on the water surface.

[0003] Therefore, it is of great practical significance to develop a bridge connection device that can be applied to special bridges on the water surface. Summary of the invention

[0004] Since the prior art has the above-mentioned defects, the present invention provides a bridge connection device applicable to a special surface bridge, which overcomes the defect that the bridge connection device cannot be adaptively rotated under stress to meet the needs of the special surface bridge.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A special bridge connection device for water surface, comprising a left bridge connection structure, a right bridge connection structure and a horizontal rotation structure;

[0007] One end of the left bridge connection structure is provided with a left soft connection section, and one end of the right bridge connection structure is provided with a right soft connection section matching the left soft connection section. The left soft connection section and the right soft connection section have the same structure, including a circular bottom plate and elastic guardrails located on both sides of the circular bottom plate;

[0008] The left soft connection section and the right soft connection section are connected by a horizontal rotation structure, and the horizontal rotation structure includes a horizontal rotation upper plate and a horizontal rotation lower plate, and the centers of the horizontal rotation upper plate and the horizontal rotation lower plate are respectively provided with a horizontal rotation upper plate rotation middle hole and a horizontal rotation lower plate rotation middle hole, the horizontal rotation upper plate is provided with two horizontal rotation upper plate symmetrical rotation C holes that are symmetrical relative to the horizontal rotation upper plate rotation middle hole, the horizontal rotation lower plate is provided with two horizontal rotation lower plate symmetrical rotation C holes that are symmetrical relative to the horizontal rotation lower plate rotation middle hole, the circular bottom plates of the left soft connection section and the right soft connection section are both provided with circular bottom plate rotation middle holes that match the horizontal rotation upper plate rotation middle hole, the left soft connection section, the right soft connection section and the horizontal rotation structure are fixedly positioned by a fixed positioning device located between the right soft connection section and the horizontal rotation upper plate. The fixed connection and the fixed positioning device include a rotating connecting rod, and the two sides of the middle part of the rotating connecting rod are respectively fixedly connected with an upper positioning shaft and a lower positioning shaft perpendicular to the rotating connecting rod, and the two ends of the rotating connecting rod are fixedly connected with a limiting rod perpendicular to the rotating connecting rod and located on the same side as the lower positioning shaft, the upper positioning shaft passes through the rotating middle holes of the two circular bottom plates and the lower positioning shaft passes through the rotating middle holes of the horizontal rotating upper plate and the rotating middle holes of the horizontal rotating lower plate, that is, the rotating connecting rod is rotatably connected with the two circular bottom plates, the horizontal rotating upper plate and the horizontal rotating lower plate, and the limiting rod passes through the symmetrically rotating C holes of the horizontal rotating upper plate and the symmetrically rotating C holes of the horizontal rotating lower plate in turn, and then is rotatably connected with the horizontal rotating upper plate and the horizontal rotating lower plate, and the horizontal rotating upper plate, the horizontal rotating lower plate and the fixed positioning device can limit the rotation angle of the two circular bottom plates.

[0009] The surface-specific bridge connection device of the present invention has a reasonable structural design. The left and right side bridge connection structures are connected by a soft connection section in cooperation with a horizontal rotating structure. The horizontal rotating upper plate, the horizontal rotating lower plate and the fixed positioning device cooperate to realize its rotation on the horizontal plane, ensuring that the two sections of the bridge can bend at a certain angle (slight rotation can limit the maximum rotation angle to meet the maximum bending radius of the cable laying) when the water surface fluctuates. It is particularly suitable for surface working environments, and can offset part of the impact of water surface fluctuations through changes in the bridge connection parts, thereby providing certain protection for the bridge and the cables inside it, and has good application prospects.

[0010] As the preferred technical solution:

[0011] In the above-mentioned surface-specific bridge connection device, a horizontal rotating structure protection cover is provided below the horizontal rotating structure to protect the horizontal rotating structure.

[0012] In the above-mentioned surface-specific bridge connection device, the limiting rod is provided with a limiting edge away from the end of the rotating connection rod, and the horizontal rotating lower plate is limited by the limiting edge.

[0013] A special bridge connection device for the water surface as described above, on the radial directions of the upper positioning shaft and the lower positioning shaft far from the end of the rotating connecting rod, an upper positioning shaft fixing pin and a lower positioning shaft fixing pin are respectively provided.

On the right bridge connection section, a right connection shaft fixing hole matching with the right telescopic slide rail is provided. The right telescopic connection shaft passes through the right telescopic slide rail and the connection shaft fixing hole to fix the right bridge connection section and the right horizontal telescopic section together. The right horizontal telescopic section is connected with the right flexible connection section. The telescopic slide rails endow the left and right bridge connection structures with a certain degree of flexibility (the telescopic length can be limited). When the water surface fluctuates, the left and right bridge connection structures can adaptively adjust the length and angle to a certain extent to offset the influence brought by the water surface fluctuation, so as to protect the bridge and the cables inside from being affected.

[0017] A special bridge connection device for the water surface as described above, the elastic guardrail is a telescopic guardrail.

[0018] The above technical solutions are only a feasible technical solution of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0036] The left flexible connection section 15 and the right flexible connection section 25 have the same structure, including a circular bottom plate and elastic guardrails (retractable guardrails) on both sides of the circular bottom plate;

[0037] The left side soft connection section 15 and the right side soft connection section 25 are connected through a horizontal rotation structure 3, and the horizontal rotation structure 3 includes a horizontal rotation upper plate 31 and a horizontal rotation lower plate 32. The centers of the horizontal rotation upper plate 31 and the horizontal rotation lower plate 32 are respectively provided with a horizontal rotation upper plate rotation middle hole 33 and a horizontal rotation lower plate rotation middle hole.
