DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 3As shown, the utility model proposes a shore connection structure for a wharf approach bridge, comprising a pile foundation 1, a movable plate 6, a connecting plate 8, a supporting plate 11, a locking assembly, a driving assembly and a control assembly. The pile foundation 1 is connected to the abutment 2, the abutment 2 is connected to the supporting plate 3, and the supporting plate 3 is provided with a pavement layer 5 flush with the mainland road surface. A slide groove 101 is provided on the pile foundation 1, and a plurality of clamping holes 102 are evenly spaced along the height direction of the slide groove 101 on the pile foundation 1. One end of the movable plate 6 is inserted into the abutment 2 and slidably connected thereto, and the movable plate 6 is rotatably connected to the approach bridge plate 7. A cavity is provided in the abutment 2, the movable plate 6 is inserted into the cavity and slidably connected to its inner wall, and an inclined surface is provided on the side of the upper surface of the abutment 2 close to the approach bridge plate 7 to reduce the height difference between the surface of the abutment 2 and the upper surface of the movable plate 6. The connecting plate 8 is connected to the wharf and is rotatably connected to the approach bridge plate 7, and the connecting plate 8 is parallel to the movable plate 6. The upper surfaces of the abutment 2, the movable plate 6, the approach bridge plate 7 and the connecting plate 8 are all provided with anti-slip grooves. Guardrails A9 are symmetrically arranged on the abutment 2, the approach bridge plate 7 and the connecting plate 8, and guardrails B10 are symmetrically arranged on the movable plate 6. Guardrails B10 are inserted into the guardrails A9 on the abutment 2 and are slidably connected thereto. The support plate 11 is slidably connected to the pile foundation 1, and the support plate 11 is connected to the connecting plate 8. The locking assembly connects the support plate 11 and the pile foundation 1. The locking assembly includes a slider 14, a cam 15, a vertical plate 16 and a clamping block 17. The slider 14 is inserted into the support plate 11 and is rotatably connected thereto, and the slider 14 is connected to the cam 15. The vertical plate 16 is located in the support plate 11 and is slidably connected thereto, and the vertical plate 16 abuts against the cam 15, and a tensioning assembly 18 is arranged in the support plate 11 to keep the vertical plate 16 against the cam 15 through the tensioning assembly 18, and the clamping block 17 is connected to the vertical plate 16, and the clamping block 17 passes through the support plate 11 and is inserted into the corresponding side clamping hole 102. The driving assembly is connected to the pile foundation 1 and drives the connecting support lock assembly to achieve the locking and unlocking of the sliding of the support plate 11. The driving assembly includes a motor 13 and a rotating shaft 12, and the motor 13 drives the connecting rotating shaft 12. The rotating shaft 12 passes through the support plate 11 and is rotatably connected thereto, and a vertical groove 121 is provided on the rotating shaft 12, and the slider 14 is located in the vertical groove 121 and is slidably connected thereto. The control assembly is connected to the motor 13. A pressure detection assembly is provided on the support plate 11, and the detection end of the pressure detection assembly is connected to the connecting plate 8, and the pressure detection assembly is connected to the control assembly.

[0027] In this embodiment, when the dock sinks, the dock drives the movable plate 8 to descend. At this time, since the support plate 11 is in a locked state, when the pressure detection component detects the pressure signal, the control component controls the motor 13 to rotate, and the motor 13 drives the shaft 12 to rotate 90 degrees. At this time, the long end of the cam is away from the vertical plate 16. The vertical plate 16 moves toward the shaft 12 under the tension of the tensioning component 18, and the block 17 is recovered synchronously. The block 17 is separated from the clamping hole 102 to release the limiting relationship between the support plate 11 and the pile foundation 1. The connecting plate 8 follows the dock to descend, and the connecting plate 7 rotates freely at the same time. The movable plate 6 slides freely for an appropriate length to ensure that the connecting plate 8 and the movable plate 6 are always parallel. When the external environment is harsh, the pressure sensor detects the pressure signal of the toggle, and the toggle signal is fed back to the control component. The motor 13 remains motionless when the block 17 is inserted into the clamping hole. The structure improves the dock's ability to resist wave impact.

[0028] Embodiment 2

[0029] like Figure 1 As shown, the utility model proposes a shore connection structure for a wharf approach bridge. Compared with the first embodiment, the vertical plates 16 include two, and the two vertical plates 16 are symmetrical about the center of the rotating shaft 12, the cam 15 is a double-headed cam, and the two distal ends of the double-headed cam are symmetrical about the center of the rotating shaft 12.

[0030] In this embodiment, the bidirectionally synchronously moving vertical plate 16 drives the two side blocks 17 to synchronously extend and retract. The two groups of blocks 17 simultaneously connect the support plate 11 and the pile foundation 1, which can improve the stability and load-bearing capacity of the device.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
