Abstract
Description
Technical Field
[0001] This application relates to the field of bridge anti-collision facilities, and in particular to a combined bridge self-floating anti-collision ring and its assembly process. Background Technology
[0002] In rivers, lakes, and seas, as the tonnage and volume of shipping increase year by year, conflicts between bridges and ships will inevitably occur. Especially when heavy rainfall causes rapid currents, ship collisions with bridge piers are frequent, causing significant damage to human life, property, and the environment. Therefore, in order to reduce the rate of ship collisions with bridges and mitigate the safety hazards caused by long-term ship impacts on bridge structures, collision protection for bridge piers is extremely important.
[0003] In related technologies, the form of a self-floating anti-collision device is as follows: an anti-collision ring is fitted around the bridge pier, floating on the water surface. Energy dissipation elements are installed on the inner edge of the anti-collision ring, which are used to directly contact the bridge pier. For bridge piers with a rectangular cross-section, the anti-collision ring is also rectangular. The assembly process of the anti-collision ring is as follows: two large U-shaped segments are assembled at the dock. Each U-shaped segment is towed away from the dock and close to the bridge pier body by a tugboat. Then, the two U-shaped segments are interlocked at the bridge pier to form a complete and closed floating anti-collision ring.
[0004] Due to the spatial constraints of the crash ring and the bridge pier, the crash ring at the bridge pier must be assembled from at least two segments from different directions, which will further increase the equipment cost or operating cost. Summary of the Invention
[0005] To address the aforementioned issues, this application provides a combined bridge self-floating anti-collision ring and its assembly process.
[0006] The combined bridge self-floating anti-collision ring provided in this application adopts the following technical solution:
[0007] A composite bridge self-floating anti-collision ring includes a ring body comprising two U-shaped segments. Each U-shaped segment has an energy dissipation component on its side facing the bridge pier. The two U-shaped segments are joined at a joint end. A connecting mechanism is provided on the ring body at the joint end to fix the two opposing joint ends. An angle ring is connected to one of the joint ends of each U-shaped segment. The angle rings of the two U-shaped segments are hinged together, and the hinge axis between the two angle rings is a first hinge axis, with its axis pointing vertically. The ring body also includes a control component for controlling the relative rotation of the two angle rings.
[0008] By adopting the above technical solution, the two U-shaped segments can rotate around the first hinge axis in a side-by-side flat state. First, one U-shaped segment is fastened to the side of the pier, and then the other U-shaped segment is rotated to go around the pier and complete the opposite fastening. This provides convenience for the transportation and splicing operation of the ring body, and the equipment requirements for this operation process are low, saving costs.
[0009] Preferably, the U-shaped segment includes a main segment and two wing segments. The two wing segments are located at opposite ends of the main segment and are fixedly connected to the main segment. The main segments of the two U-shaped segments are symmetrically arranged on both sides of the pier. The angle ring is rotatably connected to the wing segments of the U-shaped segment, and the rotation axis coincides with the axis of the angle ring itself. The two wing segments of the two U-shaped segments connected by the angle ring can also be detachably provided with the same locking member. The locking member is movably arranged relative to the wing segment, and the direction of movement is the circumference of the wing segment.
[0010] Preferably, an auxiliary groove is formed along the circumference of the wing segment, and an exit groove is formed at one end of the auxiliary groove on the wing segment. When the U-shaped segment is floating on the water surface, the exit groove is located on the side of the wing segment away from the main segment. The locking component includes a connecting rod and two locking rods. The two locking rods are located at opposite ends of the connecting rod. The locking rods are embedded in the auxiliary groove, and the opening of the exit groove is larger than the projected area of the locking rod.
[0011] By adopting the above technical solution, the locking component aims to improve the stability of the two U-shaped segments when they are stacked. During assembly, the two formed U-shaped segments are first stacked one on top of the other, with the two wing segments fitted with angle rings close together. The two locking rods of the locking component are respectively embedded in the auxiliary grooves of the two wing segments. In this state, the two wing segments are simultaneously restricted by the angle rings and the locking component and cannot be separated. When the upper U-shaped segment is flipped down and the two U-shaped segments are placed horizontally side by side, the exit grooves on the two close-to-side wing segments are aligned. At this time, the two locking rods of the locking component can be disengaged from the two exit grooves, and the two wing segments can then rotate around the first hinge axis.
[0012] Preferably, the control component includes an operating ring and a tension rope. The operating ring is connected to an angle ring and located away from the first hinge axis. The tension rope is fixedly connected to one of the operating rings, and its other end passes through the other operating ring.
[0013] By adopting the above technical solution, a tension generating device for applying tension to the tension rope needs to be installed on the ship. Under the action of the change of direction of the operating ring, the tension of the tension rope forms a torque on the angle ring originally located above and the U-shaped segment fitted thereon, which can make it rotate around the first hinge axis.
[0014] Preferably, the angle ring is divided into two hinged separate rings, with a first hinge axis located on one of the separate rings, and a second hinge axis connecting the two separate rings. The axis of the second hinge axis is parallel to the axis of the angle ring, and the angle ring is provided with a ring-forming assembly for connecting the two separate rings.
[0015] Preferably, the ring-forming assembly includes fixing blocks and fixing bolts. The number of fixing blocks is the same as the number of split rings. Each fixing block is fixedly connected to the end of the split ring away from the second hinge axis. The fixing bolt passes through one of the fixing blocks and is screwed into the other fixing block.
[0016] By adopting the above technical solution, the angle ring is variable. After the two U-shaped segments are spliced together, the task of the angle ring and the control component is completed. By rotating the split rings, the connection between the angle ring and the U-shaped segments is removed, and the angle ring can be removed from the ring body. Its own structure does not affect the normal operation of the ring body.
[0017] Preferably, the upper fixing block has a countersunk groove for the screw head of the fixing bolt, and the fixing block has a safety groove. The opening of the countersunk groove is located at the bottom of the safety groove. A safety block is slidably disposed on the fixing block and inside the safety groove. The sliding direction of the safety block is perpendicular to the length direction of the fixing bolt. The safety block has a safety hole, and the cross-section of the safety hole is greater than or equal to the cross-section of the countersunk groove.
[0018] Preferably, a safety spring is provided in the safety groove. One end of the safety spring is connected to the groove wall of the safety groove, and the other end is connected to the safety block. The end of the safety block away from the safety spring extends out of the safety groove. When the splicing ends of the two U-shaped segments abut each other, the two safety blocks abut against each other, and the safety hole is connected to the countersunk groove.
[0019] By adopting the above technical solution, during the operation, the screw head of the fixing bolt is sealed by the safety block, and the stability of the fixing bolt and the stability of the angle ring are guaranteed to a certain extent. When the U-shaped section is connected, the two safety blocks move naturally under the action of mutual abutment, so that the safety hole and the countersunk groove are connected. The operator can then insert a torque tool into the countersunk groove through the safety hole to disassemble the fixing bolt.
[0020] Preferably, the energy dissipation component includes a mounting plate and an abutment roller. The abutment roller is rotatably mounted on one side of the mounting plate. A receiving groove is provided on the side of the ring facing the pier. A buffer spring is fixedly connected to the bottom of the receiving groove. The side of the mounting plate away from the abutment roller is connected to the buffer spring. The rotation axis of the abutment roller is a vertical straight line.
[0021] By adopting the above technical solution, during the normal use of the ring structure, the energy dissipation components are used to directly contact and abut against the side wall of the pier, reducing the impact of the interaction force between the two and improving the structural durability of the ring structure.
[0022] This application also provides an assembly process for the above-mentioned composite bridge self-floating anti-collision ring, which includes the following steps in sequence:
[0023] S1: The combined bridge self-floating anti-collision ring is initially assembled so that the two U-shaped segments are stacked on top of each other, and the locking component crosses the auxiliary groove of the two U-shaped segments at the same time.
[0024] S2: Transport the two U-shaped segments stacked on top of each other to the side of the bridge pier, flip down the upper U-shaped segment so that the two U-shaped segments float side by side, and push one of the U-shaped segments laterally to the side of the bridge pier;
[0025] S3: Remove the locking piece, drag the tension rope to rotate the other U-shaped section, and fasten it to the other side of the pier;
[0026] S4: The two U-shaped segments are connected by a connecting mechanism;
[0027] S5: Remove the angle ring and control components from the ring body.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. By setting the angle ring, the two U-shaped segments can rotate around the first hinge axis in a side-by-side flat state. First, one U-shaped segment is fastened to the side of the pier, and then the other U-shaped segment is rotated to go around the pier and complete the opposite fastening. This provides convenience for the transportation and splicing operation of the ring body, and the equipment requirements for this operation process are low, saving costs.
[0030] 2. By setting up a split ring, after the angle ring completes its task, the split ring can be opened by operating the ring assembly, thereby removing the angle ring from the ring body. After that, the angle ring, the first hinge shaft, and the control assembly will leave the ring body without affecting the normal operation of the ring body. Attached Figure Description

Detailed Implementation
[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0038] Firstly, embodiments of this application disclose a combined bridge self-floating anti-collision ring, such as... Figure 1 and 2 As shown, the structure includes a ring body 2 and multiple energy dissipation components 5 located inside the ring body 2. The pier 1 enclosed by the ring body 2 has a square cross-section, and the energy dissipation components 5 are used to directly contact and abut against the sidewalls of the pier 1. The ring body 2 is composed of two mutually symmetrical U-shaped segments 21 spliced together. Each U-shaped segment 21 includes a main segment 211 and two wing segments 212. An angle ring 3 and a control component 32 are provided on the ring body 2, which are used to control the angle and changes between the two U-shaped segments 21.
[0039] like Figure 1 and 2As shown, two wing segments 212 are fixedly connected to opposite ends of the main segment 211. The length direction of the wing segment 212 is perpendicular to the length direction of the main segment 211. The cross-sections of both the wing segment 212 and the main segment 211 are approximately cylindrical. The end of the wing segment 212 furthest from the main segment 211 is the splicing end of the U-shaped segment 21. Angle ring 3 is connected to one splicing end of the U-shaped segment 21. The angle ring 3 is coaxially and rotatably connected to the wing segment 212. The angle rings 3 on the two U-shaped segments 21 are hinged to each other. The hinge axis between them is the first hinge axis 31, and the axis of the first hinge axis 31 is perpendicular to the length direction of the wing segment 212. Since the angle ring 3 is coaxially and rotatably connected to the wing segment 212, a single wing segment 212 can rotate independently relative to the angle ring 3 it is fitted with. During assembly, the two formed U-shaped segments 21 are first stacked on top of each other, with the two wing segments 212 fitted with angle rings 3 close to each other. At this time, the first hinge axis 31 is located between the upper and lower wing segments 212. To reduce damage caused by the interaction force between the two U-shaped segments 21 when they are stacked, an elastic object (not shown in the figure) can be placed between them for cushioning.
[0040] like Figure 2 and 3 As shown, in order to improve the stability of the two U-shaped segments 21 when they are stacked together, the same locking piece 25 can be detachably installed on the wing segments 212 of the two U-shaped segments 21 stacked together. The two wing segments 212 are provided with auxiliary grooves 24. The auxiliary grooves 24 and the angle ring 3 are located on the same wing segment 212. The length direction of the auxiliary grooves 24 is the circumferential direction of the wing segment 212. In the cross section of the wing segment 212, the span of the auxiliary grooves 24 is 90°. An exit groove 241 is provided on the wing segment 212 and at one end of the auxiliary groove 24. When the U-shaped segment 21 floats on the water surface, the exit groove 241 is located on the side of the wing segment 212 away from the main segment 211. The locking component 25 is I-shaped and includes a connecting rod 251 and two locking rods 252. The two locking rods 252 are welded to opposite ends of the connecting rod 251. The auxiliary groove 24 has an inverted T-shaped cross-section, and its opening allows the connecting rod 251 to pass through. The length direction of the exit groove 241 is parallel to the generatrix of the airfoil 212, and the opening area of the exit groove 241 is larger than the lateral projection area of the locking rod 252, meaning that the locking rod 252 can freely enter and exit the exit groove 241. The two locking rods 252 of the locking component 25 are respectively embedded in the auxiliary grooves 24 of the two airfoils 212. In this state, the two airfoils 212 are simultaneously restricted by the angle ring 3 and the locking component 25 and cannot be separated. When the upper U-shaped section 21 is flipped down and the two U-shaped sections 21 are placed horizontally side by side, the exit grooves 241 on the two closely adjacent wing sections 212 are opposite each other. At this time, the two locking rods 252 of the locking member 25 can be disengaged from the two exit grooves 241 respectively, and the two wing sections 212 can rotate around the first hinge axis 31.
[0041] like Figure 2 and 3As shown, the control component 32 includes an operating ring 321 and a tension rope 322. The operating ring 321 is fixedly connected to the angle ring 3 and located away from the first hinge axis 31. One end of the tension rope 322 is fixedly connected to the operating ring 321, which is originally located on the upper angle ring 3, and the other end passes through the operating ring 321, which is originally located on the lower angle ring 3, and this end is directly connected to the ship. A tension generating device (not shown in the figure) needs to be installed on the ship to apply tension to the tension rope 322. Under the action of the change in direction of the operating ring 321, the tension of the tension rope 322 forms a torque on the upper angle ring 3 and the U-shaped segment 21 fitted thereon, which can make it rotate around the first hinge axis 31.
[0042] like Figure 1 , 2 As shown in Figure 3, under the tension of the tension rope 322, the two U-shaped segments 21 rotate approximately 180° relative to each other, ultimately forming a connection between the two U-shaped segments 21. A connecting mechanism 22 is provided on the ring body 2 at the splicing end, and the splicing ends of the two U-shaped segments 21 are connected to each other, thus establishing a connection between the two U-shaped segments 21. The connecting mechanism 22 includes a connecting protrusion 221 and a giant screw 222. The connecting protrusion 221 is integrally formed at the splicing end of one of the U-shaped segments 21. A splicing groove 23 is provided at the splicing end of the other U-shaped segment 21. Both the wing segment 212 and the connecting protrusion 221 have through holes in the vertical direction. After the connecting protrusion 221 is inserted into the splicing groove 23, the through holes of the two are aligned and connected. The giant screw 222 passes through the through hole from top to bottom and is screwed into the wing segment 212. At this time, the giant screw 222 also passes through the connecting protrusion 221. Thus, the two U-shaped segments 21 that are connected to each other cannot be separated, and the complete ring body 2 is formed.
[0043] like Figure 4 and 5 As shown, after the ring body 2 is formed, the tasks of the angle ring 3 and the control component 32 are completed. In order to ensure that the angle ring 3 and other structures do not affect the normal operation of the ring body 2, the angle ring 3 is divided into two hinged split rings 33. The hinge axis between the two split rings 33 is the second hinge axis 331, and the axis of the second hinge axis 331 is parallel to the axis of the angle ring 3. The first hinge axis 31 is located on one of the split rings 33. The angle ring 3 is provided with a ring-forming component 4 for connecting the two split rings 33. The ring-forming component 4 includes a fixing block 41 and a fixing bolt 44. The number of fixing blocks 41 is the same as the number of split rings 33. A single fixing block 41 is integrally formed on the end of the split ring 33 away from the second hinge axis 331. The operating ring 321 is fixedly connected to the end of the fixing block 41 away from the split ring 33. When the U-shaped segment 21 is placed flat on the water surface, the two fixing blocks 41 on the same angle ring 3 are arranged vertically, and the fixing bolt 44 passes through the upper fixing block 41 and screws into the lower fixing block 41.
[0044] like Figure 4 and 5 As shown, when the two U-shaped segments 21 are connected, a safety groove 411 is provided on the upper fixing block 41. A safety block 42 is slidably disposed on the fixing block 41 and within the safety groove 411. The sliding direction of the safety block 42 is perpendicular to the length direction of the fixing bolt 44. A countersunk groove for the screw head of the fixing bolt 44 is provided at the bottom of the groove on the fixing block 411, that is, the safety block 42 is located above the fixing bolt 44. One end of the safety groove 411 is located on the side wall of the fixing block 41, and the safety block 42 can slide out from this end of the safety groove 411. A safety spring 43 is provided in the safety groove 411. One end of the safety spring 43 is fixedly connected to the end wall of the safety groove 411, and the other end is fixedly connected to the safety block 42. In the natural state, the end of the safety block 42 away from the safety spring 43 protrudes from the opening of the safety groove 411, and at this time, the countersunk groove is completely blocked by the safety block 42. The safety block 42 is provided with a safety hole 421. The cross-section of the safety hole 421 is larger than the cross-section of the countersunk groove. When the two U-shaped segments 21 are spliced together and the two angle rings 3 are coaxial and abut against each other, the fixing blocks 41 on the two angle rings 3 abut against each other. At the same time, the two safety blocks 42 also abut against each other and apply opposing thrusts to each other, causing the safety block 42 to retract into the safety groove 411. At this time, the safety hole 421 is coaxial with the countersunk groove. The operator can then insert a torque tool into the countersunk groove through the safety hole 421 to disassemble the fixing bolt 44.
[0045] like Figure 1 and 2 As shown, the energy dissipation component 5 includes a mounting plate 51 and an abutment roller 52. Multiple mounting plates 51 and abutment rollers 52 are provided, and each corresponds to one another. The ring body 2 has several receiving grooves 26 on the side facing the pier 1. Several buffer springs 53 are fixedly connected to the bottom of each receiving groove 26. The abutment roller 52 is rotatably mounted on one side of the mounting plate 51, and the side of the mounting plate 51 facing away from the abutment roller 52 is fixedly connected to the buffer springs 53. The roller surface of the abutment roller 52 is made of hard rubber or other elastic material. After the ring body 2 surrounds the pier 1, the rotation axis of the abutment roller 52 is a vertical straight line.
[0046] Secondly, this application also discloses the assembly process of the above-mentioned combined bridge self-floating anti-collision ring, which includes the following steps in sequence:
[0047] S1: At the dock, the ring body 2 is initially assembled. The U-shaped section 21 needs to be formed and the two U-shaped sections 21 should be stacked on top of each other. At this time, the locking piece 25 crosses the auxiliary groove 24 of the upper and lower U-shaped sections 21.
[0048] S2: The working vessel hoists the two U-shaped sections 21 stacked on top of each other to the side of the pier 1, and then flips down the upper U-shaped section 21 so that the two U-shaped sections 21 float side by side, and pushes the lower U-shaped section 21 laterally towards the pier 1 so that it crosses the pier 1.
[0049] S3: Remove the locking piece 25, start the tension generating device on the ship to drag the tension rope 322, so that the other U-shaped section 21 rotates and is fastened to the other side of the pier 1.
[0050] S4: Insert the giant screw 222, and establish a connection between the two U-shaped segments 21 through the connecting mechanism 22;
[0051] S5: Remove the fixing bolt 44, remove the angle ring 3 and control component 32 from the ring body 2, disconnect the ship from the ring body 2, and the assembly is completed.
[0052] The implementation principle of the combined bridge self-floating anti-collision ring and its assembly process in this application embodiment is as follows:
[0053] Taking a rectangular cross-section bridge pier 1 as an example, this scheme uses the segmented structure of the ring body 2 to make the segmented solid structure bypass the space occupied by the bridge pier 1 by rotating laterally, thereby realizing the encirclement of the bridge pier 1 by the ring body 2. Then, the originally separate segments are fixed to each other by the components, and the complete ring body 2 is formed.
[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
