Description

Technical field:

[0001] The invention relates to the field of pontoon bridge connection, in particular to a pontoon bridge quick connection device and an installation and connection method thereof. Background technology:

[0002] The present invention is designed in the field of pontoon bridge equipment, which is a special floating bridge equipment. The characteristics of pontoon bridges are just in line with the task requirements of ensuring that large rescue and emergency equipment can enter the disaster area from water when land routes are blocked by floods, earthquakes, etc. Therefore, pontoon bridge equipment has played an important role in emergency rescue tasks throughout history. In order to achieve land mobility and rapid erection capabilities, pontoon bridge equipment is divided into several components, which can be transported by special carriers and float in water through carriers. In order to meet the needs of road and rail transportation of cars, it is designed to be a section boat with a smaller length and transportation width. After floating in water, the section boat is expanded horizontally and connected and extended longitudinally to form a Caodu Gate Bridge with a certain loading capacity or a floating bridge of a certain length. The longitudinal connection between the section boats generally adopts a detachable connection, including single-ear hinges, double-ear hinges, latch connections, C and D hook connections, plate pin connections, etc. These connection methods are designed to reduce the increase in slope caused by changes in draft when the floating bridge is loaded and reduce the load impact that endangers the safety of the floating bridge. The connection clearance is very small, and it can be connected smoothly in a still water environment, but it is difficult to connect in a flowing water environment, especially when the blocked gate bridge is blocked, because a long floating bridge section has been formed at both ends, the inertia is large, and adjustment is difficult, and the connection is particularly difficult.

[0051] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0053] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0054] It should also be understood that, although the present application has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0055] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0056] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0057] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0058] Terminology explanation:

[0059] Term 1: Pontoon bridge - a bridge structure or floating bridge that uses boats as bridge legs.

[0060] Term 2: Section boat - a single section boat equipped with a specified number of superstructure equipment and anchors.

[0061] Term 3: Bridge boat - a bridge boat that can independently form a floating bridge section.

[0062] Term 4: Portal bridge - a combination of boat and superstructure or bridge boat.

[0063] Term 5: Bridge Section Portal Bridge - A portal bridge used to make up the mid-river portion of a floating bridge.

[0064] Term 6: Blocked gate bridge - the gate bridge that is used to connect the floating bridge sections at the end when erecting the floating bridge to make the floating bridge connected.

[0065] Term 7: Floating - the action of unloading pontoon equipment from shore or vehicle into the water.

[0066] Some domestic research institutes have developed a variety of solutions for the rapid connection technology of pontoon bridges and pontoons, including butterfly joints and flexible joints for connecting offshore pontoons. However, the results are not good and they cannot solve the problem of difficult pontoon bridge connection in flowing water and wave environments. Internationally, the research project "Future Pontoon Bridge" funded by the Japanese Defense Agency proposed a solution for the longitudinal connection between the pontoon bridges in offshore applications.

[0067] The section boat will be affected by the current in the flowing water and tend to drift downstream. The existing method is to stand 2 to 3 people at the opposite ends of the two sections of the boat to be connected, pull the two sections of the boat together and hold them with hooks or mooring ropes, and then have two people standing at the opposite ends of the two sections of the boat operate the transmission mechanism to connect the longitudinal joints. In this process, the premise for the smooth connection of the section boat is that the single ear plate can be smoothly embedded in the distance between the double ear plates, and the removal pin holes of the single ear plate and the double ear plates are concentric. Usually, under the condition of flowing water, the section boats on both sides should be able to move towards each other without center deviation. When the flow rate is low, the standard number of operators can still control the alignment of the section boats. When the flow rate is high, more people are needed to control the alignment of the section boats, and it may even fail. Under wave environment conditions, the segmented boats will move with six degrees of freedom under the action of waves. Since the size of the segmented boats is relatively small, the movement amplitude in the waves is large, which makes it more difficult to align the interconnected segmented boats, and then it is difficult to complete the single-ear and double-ear pin connection, resulting in the failure of the gate bridge structure and the pontoon erection.

[0068] From the above analysis, it can be concluded that as long as the two connected boats can be aligned in center and height, the longitudinal joints can be aligned, the latch can be smoothly inserted, and the longitudinal connection can be completed. Different from the traditional operation method of people using hooks and poles and pulling ropes, the present invention designs a guide device with functions from rough positioning to precise positioning to locking and fixing, and these functions are realized by the guide device using the kinetic energy of the two boats moving towards each other.

[0069] The invention solves the problem of difficulty in longitudinally connecting the segmented boats of pontoon bridge equipment under flowing water and wave environment conditions, thereby reducing the erection time of pontoon bridge equipment and expanding its application at sea.

[0071] The invention realizes the rapid connection of the pontoon bridge section and the pontoon boat in terms of the guiding design of the tapered pin and the tapered hole of the longitudinal joint, the collision locking of the hook and the hook seat, the longitudinal extension and contraction of the tapered pin to meet the guiding length requirement and the auxiliary hook disassembly.

[0072] like Figures 1 to 14 As shown, in one embodiment, the present invention provides a pontoon bridge quick connection device, the pontoon bridge quick connection device comprises at least two sections of the section boat 10, the at least two sections of the section boat comprises a first section boat 1 and a second section boat 2;

[0073] At least one guide cone hole 11 is provided on one end side of the first boat 1;

[0074] At least one taper pin assembly 21 is arranged on the side of one end of the second section boat 2. The taper pin assembly 21 includes a telescopic cylinder 211. The telescopic cylinder 211 is connected to the second section boat 2. The piston rod 212 of the telescopic cylinder 211 is extended and inserted into the guide taper hole 11 to achieve connection.

[0075] In the present embodiment, a specific structure of a pontoon bridge quick connection device is provided. The first section boat 1 and the second section boat 2 are both flat structures. In actual application, multiple section boats 10 are connected end to end in sequence to form a long bridge structure. In this embodiment, we use the first section boat 1 and the second section boat 2 as one of the connection methods as the basis to explain the connection method of multiple section boats 10. We insert the extended part of the telescopic cylinder 211 into the guide cone hole 11. The specific structure of the specific guide cone hole 11 will be further described later, so it will not be repeated here. The guide cone hole 11 has a certain guiding effect. The reason is that it is located on the side facing the outside as a cone hole, which helps to solve the technical problem in the prior art that the section boats are prone to failure due to their own movement during the docking process.

[0076] In one embodiment, a taper pin seat 22 is provided on the end surface of one end of the second section boat 2, one end of the telescopic cylinder 211 is connected to the taper pin seat 22, the end of the telescopic cylinder 211 extends out of the taper pin seat 22, and a hinged hook 23 is provided at the extended end of the piston rod 212, and the taper pin assembly 21 includes a first guide nylon plate 24 and a guide taper pin 25;

[0077] The first guide nylon plate 24 is disposed between the inner wall of the taper pin seat 22 and the telescopic oil cylinder 211;

[0078] One end of the guide cone pin 25 is connected to the end of the piston rod 212, and the hook 23 is hinged on the guide cone pin 25, and the small end of the guide cone pin 25 faces the direction of the guide cone hole 11;

[0079] A lap shaft 26 of the hook 23 is provided at the bottom of the guide tapered hole 11 , so that the hook 23 extends into the guide tapered hole 11 and overlaps with the lap shaft 26 .

[0080] In this embodiment, a telescopic cylinder 211 is provided for specifically connecting to the equipment. After the hook 23 is inserted, the outside of the hook 23 is an arc-shaped structure. After the arc-shaped structure abuts against the lap shaft 26, the lap shaft 26 will lift the hook 23 along the arc, and then the hook 23 falls down by its own gravity and hangs on the lap shaft 26. At this point, the hook 23 is hung on the lap shaft 26.

[0081] In one embodiment, a crowbar hole 12 is provided on the upper end surface of the first casing boat 1 .

[0082] In this embodiment, a specific implementation of the crowbar hole 12 is provided. In order to achieve faster docking of the joint boat 10, a crowbar can be inserted into the crowbar hole 12 to guide it to be connected and fixed as soon as possible.

[0083] In one embodiment, a horn cone opening 13 facing outward is provided at one end of the guide cone hole 11 close to the end surface.

[0084] In this embodiment, a guide cone hole 11 is provided with a horn cone opening 13 , and the guide cone pin is further introduced into the guide cone hole 11 through the structure of the horn cone opening 13 .

[0085] Except for the longitudinal freedom of movement, the other relative freedoms of the two sheathed boats are completely restricted, and the two sheathed boats continue to move toward each other.

[0086] In one embodiment, the guide cone hole 11 and the cone pin assembly 21 are located on the left and right sides of the section boat, and on a section of the section boat, the guide cone hole 11 and the cone pin assembly 21 are respectively arranged on the left and right sides of one end, and the other end of the section boat is also provided with the guide cone hole 11 and the cone pin assembly 21, and the guide cone hole 11 and the cone pin assembly 21 are staggered on both sides.

[0087] In one embodiment, the lap shaft 26 is laterally inserted into the guide tapered hole 11 from the side of the joint boat 10 .

[0088] In one embodiment, a fitting hole 3 is provided on the end surface where the first section boat 1 and the second section boat 2 are connected.

[0089] In one embodiment, the piston rod end portion matches the outer contour of the middle cross section of the telescopic oil cylinder 211 and the guide tapered hole 11 .

[0090] In one embodiment, the end of the telescopic cylinder 211 is hinged to the bottom of the hole of the pin shaft 22 .

[0091] In one embodiment, the present invention further provides a method for installing and connecting a pontoon bridge quick connection device, the method for installing and connecting a pontoon bridge quick connection device comprising:

[0092] The first section of the sheathing boat 1 and the second section of the sheathing boat 2 are connected end to end in water, and are connected after the guide cone hole 11 and the cone pin assembly 21 are automatically corrected and inserted.

[0093] Beneficial effects:

[0094] Regardless of whether the section boat is swinging horizontally, vertically, vertically, rolling, pitching, or swaying in the water, when the two section boats connected to each other are approaching, the guide cone pin is easily introduced into the cone hole of the guide cone pin structure because of the large gap between the cone end of the guide cone pin and the guide cone hole structure, thereby initially limiting the movement range of the two section boats to only within the gap between the guide cone pin and the cone hole of the guide cone pin structure. As the two section boats are longitudinally drawn together, the cone end of the guide cone pin is gradually introduced into the square hole of the cone hole structure until the straight section of the guide cone pin is introduced. In the square hole of the tapered hole structure, the relative movement freedom of the two sheathed boats is completely restricted except for the longitudinal movement freedom. The two sheathed boats continue to move toward each other. When the hook hits the hook seat, the hook is lifted by the hook seat, and the two sheathed boats continue to move toward each other. When the longitudinal end faces of the two sheathed boats fit together, the hook gap is just above the hook seat. The hook covers the hook seat under the action of gravity, thereby locking the longitudinal movement freedom of the two sheathed boats. The centers of the single and double ear pin holes of the bottom joint coincide, and the pins can be smoothly inserted. The present invention can make the pontoon bridge conveniently and quickly complete the longitudinal connection of the sheathed boats in a flowing water environment and a wave environment, which is conducive to the rapid completion of the Caodumen bridge structure and the erection of the floating bridge, thereby saving the operation time of the Caodumen bridge structure and the erection time of the floating bridge, reducing the number of operators and the labor intensity of the operators, and providing a hardware foundation for realizing the automatic connection of the sheathed boats.

[0095] A pontoon bridge quick connection joint is a collision-type docking, which divides the entire longitudinal connection into two actions: the cone pin and the cone hole are hard-guided and adjusted to the center, the power system moves in opposite directions to dock, the hook hits the hook seat to complete the locking and positioning, and the cylinder pin is inserted into the single and double ear holes to complete the longitudinal bottom connection. The structure is simple and can be easily installed and connected with the joint boat. The quick connection can be achieved through the guidance of the cone hole and the cone pin, and the collision locking of the hook and the hook seat.

[0096] Different from the existing single-ear and double-ear connections, C-D hook connections, butterfly pin connections and other structural forms of the existing pontoon bridge quick-connect connectors, the present invention has made innovative designs in the structural form and working principle of the quick-connect connector. In terms of the working principle, the quick connection process is decomposed into two processes: guiding positioning and locking and fixing. The guiding positioning is achieved through the tapered pin and the tapered pin hole, so that it can adapt to a larger range of relative movement of the joint boat and realize the transition from rough positioning to precise positioning, thereby ensuring the alignment of the bottom longitudinal single ear and the longitudinal double ears; the fixation is achieved through the tapered pin and the tapered pin hole to achieve the remaining degrees of freedom of movement except for the longitudinal displacement, and the longitudinal degree of freedom of movement is locked by the collision lock of the hook and the hook seat, and the collision force is cleverly converted into a tangential force to flip the hook upward. At the same time, when the hook notch is moved to the top of the hook seat by gravity, the inner arc of the hook falls on the hook seat, thereby locking the longitudinal movement freedom. The structure is designed with a tapered pin and a tapered hole as the guide, which can realize the transition from rough positioning to precise positioning when the two connected sheathed boats have a large relative motion range. The tapered hole is designed as a hollow structure with a telescopic cylinder installed inside to realize the longitudinal extension and retraction of the tapered pin, meeting the requirements of both transportation and working states and auxiliary separation.
