Description

Technical Field

[0001] The invention relates to the technical field of approach bridges, in particular to a wharf approach bridge structure. Background Art

[0002] The wharf approach bridge is an important part of the port or wharf. It is usually designed to be relatively long. The main purpose is to slow down the up and down slope of the vehicle so that the vehicle can smoothly and safely transition from the shore to the wharf or ship. This design helps to improve transportation efficiency and ensure the safety of personnel and goods. The wharf approach bridge refers to the use of a bridge to connect the wharf with the highway (road) when the water level fluctuates greatly or the riverbed slope is too steep to set up an approach. This bridge is called a wharf approach bridge. The characteristics of the approach bridge are that the width is not large, generally 8 to 15m; the vertical load is light, and it is generally only affected by natural horizontal loads (wave force and water flow force), without ship loads; so a light structure can be used. According to the local natural conditions and instructions for use, the use of approach dikes or approach bridges can also be combined. The approach dike is used in the shallow water section near the shore, and the approach bridge is used in the deep water section away from the shore.

[0003] The existing wharf approach bridge still has certain deficiencies in actual use: the existing wharf approach bridge lacks a supporting structure for the middle part of the bridge body, and only supports and fixes the two ends of the bridge body. This means that in the absence of a supporting structure, the force on the approach bridge will be more concentrated in certain parts, such as the two ends or the mid-span position. This uneven force distribution may lead to excessive local stress, thereby causing structural destruction or damage. Based on the existing technical deficiencies, the present invention designs a wharf approach bridge structure. Summary of the invention

[0012] As a preferred technical solution of the present invention, threaded rods are installed on the internal threads of the two triangular blocks, and telescopic rods are movably installed inside the two triangular blocks.

[0013] As a preferred technical solution of the present invention, a mounting plate is fixedly mounted on one end of the two telescopic rods, and an anti-collision airbag is rotatably mounted between the two mounting plates.

[0014] As a preferred technical solution of the present invention, cable arrangement structures are provided on both sides of the top of the bridge body, and the two cable arrangement structures include three fixed support rods, cable arrangement tubes are fixedly installed inside the three fixed support rods, and multiple wiring openings are opened on the outer surfaces of the two cable arrangement tubes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A dock approach bridge structure, after the bridge body is erected through the supporting structure, two workers pull the pull plates on both sides at the same time, and at this time, the two springs are stretched to drive the positioning pins out of the fixing holes. At this time, the sliding rod can be pulled downward, and the buoyancy tube stops after contacting the water, and then the pull plate is released to release the spring force and reset, so that the positioning pins are inserted into the fixing holes again and fixed, thereby supporting the middle part of the bridge body through the buoyancy generated by the contact of multiple buoyancy tubes with water, thereby avoiding structural damage caused by uneven force on the bridge body, and improving the stability and durability of the bridge body;

[0017] 2. The anti-collision structure of the wharf approach bridge structure is used. After the installation is completed, the staff will loosen the threaded rods on both sides by twisting them in turn, and then push the two telescopic rods inward, so that the installation plate can drive the anti-collision airbag to move forward, so that the anti-collision airbag can expand the protection range, avoid and reduce the damage caused by the collision of the ship, and improve the safety of the device;

[0018] 3. This kind of wharf approach bridge structure uses a cable-laying structure. After the erection is completed, the workers fix multiple fixed support rods on the top, pass the cable-laying pipe through the inside of the structure, and then pass the pipeline through the cable-laying pipe, so as to avoid the hanging pipeline under the bridge affecting the appearance and safety.

[0029] See also Figure 1-2 A connecting plate 4 is fixedly installed on one side of the outer surface of the bridge body 1. Articulated seats 5 are fixedly installed on both sides of the top of the connecting plate 4. A cavity is opened inside the bridge body 1, and a plurality of weight-reducing plates 6 are fixedly installed inside the cavity. A fixing plate 7 is fixedly installed on one side of the outer surface of the bridge body 1. Positioning holes 8 are opened on both sides of the outer surface of the fixing plate 7.

[0030] The weight of the bridge body 1 can be reduced by setting the weight-reducing plate 6. The other end of the bridge body 1 can be flexibly connected to the floating bridge by being hingedly connected to the shore by the hinge seat 5. The two positioning holes 8 can be fixedly connected to the floating bridge.

[0031] See also Figure 1 and Figure 7 The two sides of the outer surface of the bridge body 1 are fixedly mounted with anti-collision structures 9, and the two anti-collision structures 9 include triangular blocks 91. The internal threads of the two triangular blocks 91 are mounted with threaded rods 92, and the insides of the two triangular blocks 91 are movably mounted with telescopic rods 93. One end of the two telescopic rods 93 is fixedly mounted with mounting plates 94, and an anti-collision airbag 95 is rotatably mounted between the two mounting plates 94.

[0032] After the staff loosens the threaded rods 92 on both sides in turn, they push the two telescopic rods 93 inward, so that the mounting plate 94 drives the anti-collision airbag 95 to move forward, thereby expanding the protection range of the anti-collision airbag 95, which can prevent 1 from reducing the damage caused by the collision of the ship.

[0033] See also Figure 1 and Figure 6 , cable arrangement structures 10 are arranged on both sides of the top of the bridge body 1, and the two cable arrangement structures 10 include three fixed support rods 101, and cable arrangement tubes 102 are fixedly installed inside the three fixed support rods 101, and multiple wiring openings 103 are opened on the outer surfaces of the two cable arrangement tubes 102.

[0034] The staff fixes a plurality of fixing rods 101 on the top of 1 , passes the cable duct 102 through the inside thereof, and then passes the pipeline through the cable duct 102 .

[0035] Working principle: when a dock approach bridge structure is used, the hinge seat 5 is first hinged to the shore, and the other end is connected to the floating bridge through the positioning hole 8. After the bridge body 1 is erected, two workers pull the pull plates 39 on both sides at the same time. At this time, the two springs 310 are stretched to drive the positioning pin 38 to disengage from the fixing hole 33. At this time, the sliding rod 32 can be pulled downward and stopped after the buoyancy tube 36 contacts the water. Then, the pull plate 39 is released to release the spring 310 and reset it, so that the positioning pin 38 is inserted into the fixing hole 33 again and fixed. In this way, the buoyancy generated by the contact between multiple buoyancy tubes 36 and water can support the middle part of the bridge body 1, so that This avoids structural damage caused by uneven force on the bridge body 1 and improves the stability and durability of the bridge body 1. Then, the staff loosens the threaded rods 92 on both sides in turn, and pushes the two telescopic rods 93 inward, so that the mounting plate 94 drives the anti-collision airbag 95 to move forward, thereby expanding the protection range of the anti-collision airbag 95, which can prevent 1 from reducing the damage caused by ship collision to 1 and improve the safety of the device. Finally, multiple fixed support rods 101 are fixed to the top of 1, and the cable tube 102 is passed through it from the inside to fix it, and then the pipeline is passed through the cable tube 102, thereby avoiding the suspension of pipelines under the bridge to affect the appearance and safety.
