Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floating dock facilities, in particular to a heart-shaped pile structure of a movable approach bridge of a floating dock. Background Technique
[0002] The floating dock is one of the important dock types on inland waterways, with the characteristics of simple structure, low project cost, wide applicability, etc. The floating dock usually consists of a pontoon, the anchor system of the pontoon, an approach bridge and a revetment, etc. Since the pontoon needs to rise and fall with the change of water level, the pontoon, the anchor chain and the approach bridge are all movable during use, which is a significant difference between the floating dock and the fixed dock. The outermost span of the approach bridge is the movable approach bridge, which can be a single-span movable approach bridge or a multi-span approach bridge according to the distance from the water area. In the case of a multi-span approach bridge, the other spans towards the shore can be movable or fixed. One end of the movable approach bridge is placed on the pontoon, and the other end is placed on the bridge platform on the land or on the end pier of the approach bridge.
[0003] To ensure the safe operation of the movable approach bridge, the conventional method is to set a steel chain to fix at the end of the movable approach bridge. Since the steel chain cannot be set too heavy, the force is limited and the chain fixation results in a limited movement range of the approach bridge. When the water level has a large amplitude change during the flood season and the dry season, and the angle of the movable approach bridge changes greatly, this method cannot play a good safety protection role.
[0004] In view of this, it is necessary to propose a heart-shaped pile structure of a movable approach bridge of a floating dock to solve or at least alleviate the above defects. Content of the Utility Model

[0030] Please refer to the attached Figures 1 to 4 As shown in the figure, a heart-shaped pile structure of a floating dock movable approach bridge in an embodiment provided by the present utility model includes a pile body 10 and a connecting mechanism 20 for connecting the movable approach bridge 30; wherein,
[0031] The pile body 10 includes a connecting portion 110 for connecting an external pier 40 and a vertical through portion 120 matching with the connecting mechanism 20. The connecting mechanism 20 is provided with a limiting hole 211 for the vertical through portion 120 to pass through. The connecting mechanism 20 is movably sleeved around the vertical through portion 120 through the limiting hole 211. A limiting mechanism 140 for preventing the connecting mechanism 20 from vertically disengaging from the vertical through portion 120 is further provided on the vertical through portion 120.
[0032] As Figure 1 shown, the aperture of the limiting hole 211 is larger than the outer diameter of the vertical through portion 120. Preferably, it can be set in the form of a waist-shaped hole. During the operation of the dock, due to the movement of the movable approach bridge caused by waves or water level, the connecting mechanism 20 is driven to fluctuate. Since the connecting mechanism 20 and the pile body 10 are movably connected, the limiting hole 211 provides a certain space for movement adaptation. Therefore, it can meet the movement of the movable approach bridge 30 caused by waves or water level during the operation of the dock and can play a good safety protection role for the movable approach bridge 30. At the same time, in this application, it is not a steel chain connection, but a connecting structure 20 is adopted. For example, a connecting plate is used to connect with the movable approach bridge 30, increasing the connecting area. In addition, since the connecting structure is sleeved around the vertical through portion 120, the horizontal flipping of the movable approach bridge 30 is restricted to a large extent, improving its stability.
[0033] As a preferred embodiment, the limiting mechanism 140 is a limiting bolt. A transverse bolt hole 1211 for the limiting bolt to penetrate is formed in the first through section 121. The limiting bolt penetrates through the transverse bolt hole 1211 and extends to a position beyond the limiting hole 211 to prevent the connecting mechanism 20 from vertically disengaging from the vertical through section 120.
[0034] Specifically, during installation, after the first connecting plate 210 is sleeved around the first through section 121 through the limiting hole 211, the limiting bolt penetrates through both ends of the transverse bolt hole 1211 and is fixed with a nut. Among them, the limiting bolt penetrates through the transverse bolt hole 1211 and extends to a position beyond the limiting hole 211. Thus, when the water level rises, the movable approach bridge 30 floats upward, driving the first connecting plate 210 to move upward along the vertical through section 120. After abutting against the limiting bolt, it will not continue to move upward and will not disengage / jump out of the vertical through section 120, effectively ensuring the safety and reliability of the movable approach bridge 30.
[0035] As a preferred embodiment, the connecting mechanism 20 includes a first connecting plate 210 and a second connecting plate 220. The first connecting plate 210 and the second connecting plate 220 are connected. A limiting hole 211 is formed in the middle of the first connecting plate 210. The second connecting plate 220 is used to connect the movable approach bridge 30.
[0036] As a preferred embodiment, the vertical through section 120 is columnar. The vertical through section 120 includes a first through section 121 and a second through section 122 connected in sequence from top to bottom. The outer diameter of the first through section 121 is smaller than the outer diameter of the second through section 122. A wear-resistant bushing 130 is sleeved on the outer periphery of the first through section 121. The wear-resistant bushing 130 is installed at the top of the second through section 122.
[0037] It should be noted that the wear-resistant bushing 130 can be sleeved on the first through section 121 corresponding to the frequently changing water level. The wear-resistant bushing 130 contacts the waist-shaped hole. By using wear-resistant materials, its service life can be increased. Or, in other embodiments, such as using a self-lubricating bushing, it can meet the requirements when cooperating with the waist-shaped hole, having a good lubrication effect and reducing friction.
[0038] Furthermore, a reinforcing rib plate 230 for connecting the first connecting plate 210 and the second connecting plate 220 is further included. By providing the reinforcing rib plate 230, the overall structural strength of the first connecting plate 210 and the second connecting plate 220 can be increased, such as Figure 2As shown, multiple reinforcing ribs 230 can be provided. For example, long strip-shaped reinforcing ribs 230 are provided on both sides, above and below the first connecting plate 210, and two reinforcing ribs 230 with shorter dimensions are provided at the middle position of the first connecting plate 210.
[0039] Further, as Figure 2 shown in FIG. 2 or FIG. 3, the limiting hole 211 is an elongated hole, and the extending direction of the elongated hole is perpendicular to the second connecting plate 220. By setting the limiting hole 211 as an elongated hole, the requirement for the movement of the movable approach bridge 30 caused by waves during the operation of the dock can be met. Preferably, the extending direction of the elongated hole is perpendicular to the second connecting plate 220, that is, a larger movement space can be provided along the water flow direction, and the allowable fluctuation range in the direction perpendicular to the water flow is smaller.
[0040] Further, a reinforcing structure 240 is provided on the hole wall of the elongated hole. Since the elongated hole frequently contacts the vertical through portion 120 or the wear-resistant bushing 130, the structural strength and service life of the hole wall of the elongated hole can be increased by providing the reinforcing structure 240. The material and shape of the reinforcing structure 240 can be set according to actual needs. As a preferred example, the reinforcing structure 240 is a profiled steel reinforcing ring welded to the hole wall of the elongated hole.
[0041] Further, as Figure 2 shown in FIG. 3 or FIG. 4, the connecting portion 110 is a horizontal plate, and the horizontal plate is provided with a plurality of bolt holes 111 for the embedded bolts 112 embedded in the external pier 40 to pass through, and the horizontal plate is connected to the external pier 40 through the embedded bolts 112. The embedded bolts 112 can be embedded in the external pier 40 in advance, and the horizontal plate and the external pier 40 can be connected by tightening the embedded bolts 112, thereby providing support for the stability of the movable approach bridge 30.
[0042] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
