Description

Technical Field

[0001] The invention relates to the technical field of bridge pier protection, in particular to a lifting self-locking soft ball for bridge pier protection. Background Art

[0002] The bridge pier is an important part of the supporting bridge structure. Its main function is to bear the bridge deck load and transfer the load to the foundation. The main function of the pier is to bear the vertical and horizontal loads from the bridge superstructure, including traffic loads, wind loads, earthquake loads, etc. The pier provides a stable support for the bridge to ensure that the bridge remains balanced and safe during use. The pier is usually made of materials such as concrete, steel or stone. The specific choice depends on the design requirements, environmental conditions and economy. The pier is widely used in various types of bridges, including highway bridges, railway bridges, suspension bridges, beam bridges, etc. Different types of bridges will differ in the design and construction of the pier. The bridge pier is a key part of the bridge structure, and its design and maintenance are crucial to the safety and stability of the bridge. Reasonable pier design can effectively improve the service life and safety of the bridge.

[0003] In recent years, due to the increasing cost of land transportation and the resumption of navigation on some rivers that have been closed for many years, many goods have abandoned traditional land transportation and switched to water transportation. With the increase in the number of ships, the probability of ships colliding with bridge piers in the waterway has greatly increased. The existing bridge pier protection is achieved by increasing the strength of the pier, setting guardrails and setting protective piles. The protection effect is achieved without considering the protection of the ship itself, which can easily cause damage to the ship. In addition, it is troublesome to replace the guardrails and protective piles after they are damaged by collision. When the water level rises, the protective facilities may be submerged, causing the ship to pass over the protective facilities and collide with the bridge pier. Summary of the invention

[0015] Working principle: The limit strip 5 and the limit column 605 are installed on the side surface of the base pier body 2 by using expansion screws, etc., and then the box 1 is installed on the limit strip and placed on the water surface. The internal energy-absorbing material 304 is filled in the interior of the soft ball device 3 through the inner flange 310, and then the axial force traction ring 311 set on the sealing flanges 308 at both ends is connected together by ropes, and then the sealing flange 308 is installed on the inner flange 310 through the second connecting bolt 309. The skeleton material 302 is a soft linear fiber. One end of the box 1 is passed through the steel ring 307, and then it is reversed and installed, and then the outer flange is 305 is installed by the first connecting bolt 306. After filling, the soft ball device 3 is installed on the front concave surface of the box body 1 through the strapping belt 403. When there is no water in the mobile water tank 601, the buoyancy of the floating rod 604 in the water lifts the mobile water tank 601. At this time, the inclined surface block 603 is pushed toward the direction of the limiting column 605 under the action of the spring 608, and the groove set on the limiting column 605 is clamped, so as to fix the box body 1. When the water level rises, the water flows over the box body 1 and flows into the mobile water tank 601 through the hole groove set on the box body 1. At this time, the gravity in the mobile water tank 601 becomes larger and exceeds the supporting force provided by the inclined surface block 603 and the floating force. The buoyancy provided by the float rod 604 causes the mobile water tank 601 to move downward through the inclined surface on the inclined surface moving block 609 and the inclined surface on the inclined surface clamping block 603 to move the inclined surface clamping block 603 outward and push it out. At this time, the limit on the box body 1 is released. At the same time, under the action of the buoyancy of the box body 1 and the soft ball device 3 themselves, the box body 1 moves upward to the water surface. At this time, the water filter port 612 moves to the position of the water outlet set on the box body 1, and the water in the mobile water tank 601 flows out through the water filter port 612 and the water outlet. At this time, the buoyancy of the float rod 604 and the upward force of the inclined surface of the inclined surface clamping block 603 move the mobile water tank 601 upward to its original position. At this time, the inclined surface clamping block 603 also moves upward to the original position. Return to the original position and clamp the groove set on the limit column 605 to limit the box body 1. When the water level drops to below the floating rod 604, the gravity of the floating rod 604 and the movable water tank 601 itself is greater than the inclined support force on the inclined surface block 603. At this time, the movable water tank 601 moves downward and pushes the inclined surface block 603 open to release the limitation on the box body 1. The box body 1 moves downward and falls onto the water surface. Then the floating rod 604 rises through the buoyancy of the water and pushes the movable water tank 601 upward. The inclined surface block 603 returns to its original position to limit the box body 1. When the soft ball device 3 is damaged, unscrew the connecting pin 402 and remove the strapping belt 403 for replacement.

[0016] (III) Beneficial effects

[0017] The present invention provides a lifting self-locking soft ball for protecting bridge piers. It has the following beneficial effects:

[0018] 1. When the water level rises, water flows into the mobile water tank in the lifting device, increasing the weight to drive the mobile water tank downward, thereby driving the inclined surface block to move outward and release the limit on the limit column. At the same time, it moves upward to a place flush with the water surface through the buoyancy of itself and the soft ball device. After that, the water flows out, and the inclined surface block returns to its original position under the action of the spring and limits itself again, automatically realizing up and down movement and positioning.

[0019] 2. The ship impact is buffered by the outer layer rubber, skeleton material, inner layer rubber and internal energy-absorbing material, and the deformation of the sphere during impact is mitigated by the outer flange, steel ring and sealing flange.

[0020] 3. A self-locking strapping device is provided to install the soft ball device, so that it is convenient to replace the soft ball device when it is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] When there is no water in the mobile water tank 601, the buoyancy of the floating rod 604 in the water will lift the mobile water tank 601. At this time, the inclined block 603 is pushed toward the direction of the limiting column 605 under the action of the spring 608, and the groove set on the limiting column 605 is stuck, so as to fix the box body 1. When the water level rises, the water flows over the box body 1 and flows into the mobile water tank 601 through the hole groove set on the box body 1. At this time, the gravity in the mobile water tank 601 becomes greater and exceeds the supporting force provided by the inclined block 603 and the buoyancy provided by the floating rod 604. The mobile water tank 601 moves downward through the inclined surface on the inclined moving block 609 and the inclined surface on the inclined block 603 to move the inclined block 603 outward and push it out. At this time, the limit on the box body 1 is released. At the same time, under the action of the buoyancy of the box body 1 and the soft ball device 3, the box body 1 moves upward to the water surface. At this time, the water filter port 612 moves When the water level reaches the position of the water outlet set on the box body 1, the water in the mobile water tank 601 flows out through the water filter port 612 and the water outlet. At this time, the buoyancy of the floating rod 604 and the upward force of the inclined surface of the inclined surface of the inclined surface block 603 move the mobile water tank 601 upward to its original position. At this time, the inclined surface block 603 also returns to its original position to clamp the groove set on the limiting column 605, thereby limiting the box body 1. When the water level drops to below the floating rod 604, the gravity of the floating rod 604 and the mobile water tank 601 itself is greater than the inclined support force on the inclined surface of the inclined surface block 603. At this time, the mobile water tank 601 moves downward and pushes the inclined surface block 603 open to release the limitation on the box body 1. The box body 1 moves downward and falls onto the water surface. Then the floating rod 604 rises through the buoyancy of the water to push the mobile water tank 601 upward, and the inclined surface block 603 returns to its original position to limit the box body 1.
