Description

Technical Field

[0001] The invention belongs to the technical field of novel floating bridge modules, and in particular relates to a pneumatic fast floating bridge module based on a rigid-flexible combined lattice structure and a use method thereof. Background Art

[0002] As a temporary water transport infrastructure, floating bridges play an important role in wartime, disaster relief and special transportation. Traditional floating bridges are mostly made of steel or aluminum alloys. They rely on floating modules on the water to carry the weight of vehicles, equipment and personnel. They are temporarily built on rivers, lakes and other waters to provide support for short-term traffic. With the development of technology, the design of floating bridges has evolved from simple rigid structures to the introduction of lighter, more convenient materials and more efficient assembly methods.

[0003] The traditional floating bridge structure currently has the following shortcomings: 1. Excessive weight, difficult to transport and build: Traditional floating bridges often use rigid materials such as steel or aluminum alloy. Although this improves the carrying capacity of the floating bridge, it also increases the weight of the floating bridge, resulting in complexity and time-consuming transportation and construction. 2. Lack of rapid deployment capabilities: In an emergency, the traditional floating bridge system is difficult to deploy quickly due to its design complexity. When a temporary passage needs to be quickly built in sudden disasters or wartime, this slow deployment efficiency may delay the rescue opportunity. 3. Insufficient adaptability: Traditional floating bridges usually rely on static designs and lack the ability to adaptively adjust according to environmental changes. In waters with large water level fluctuations or in river sections with turbulent water flow, it is difficult for traditional floating bridges to ensure stability, which can easily lead to dangerous situations. 4. Insufficient energy absorption and vibration reduction capabilities: Due to factors such as vibration and wave impact when vehicles pass through the floating bridge, the traditional floating bridge design often lacks an effective energy absorption and vibration reduction mechanism, which affects the long-term durability of the floating bridge and increases maintenance costs.

[0004] Therefore, the art needs to develop a pneumatic fast floating bridge module based on a rigid-flexible lattice structure and a method of using the same, which can effectively solve the above problems. Summary of the invention

[0020] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0021] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0022] Example like Figure 1 As shown, a pneumatic fast floating bridge module based on a rigid-flexible lattice structure includes a plurality of pneumatic fast floating bridge module units 1, each of which can be assembled in four directions: front, back, left, and right. The connection structure 2 of a single pneumatic fast floating bridge module based on a rigid-flexible lattice structure is shown in detail and is distributed as follows: Figure 2 As shown, the connection method adopts a bolt hole docking method, which is distributed in the front, back, left and right directions, and is used to connect the pneumatic fast floating bridge module units 1. The connection structure 2 is staggered up and down on both sides of the pneumatic fast floating bridge module unit 1.

[0023] The pneumatic fast floating bridge module unit 1 is composed of a lattice structure floating module 3 and a multi-channel gas management device 4. The floating body of the lattice structure floating module 3 is a lattice structure, and the lattice structure floating module 3 includes a working state and a contracted storage state, and the working state and the contracted storage state are quickly switched in a pneumatic manner. Figure 3 As shown, the lattice structure floating module 3 provides the main floating function, and the multi-channel gas management device 4 manages the gas in the lattice structure floating module 3 to achieve the conversion between the two states and the stability in the working state.

[0024] like Figure 4As shown, the lattice structure floating module 3 is composed of a lattice structure floating body 5, an air film 6 and a supporting inflatable column 7. The lattice structure floating body 5 plays the most important floating function. The air film 6 wraps the lattice structure floating body 5. The air film 6 adopts a highly elastic and highly sealed film. When in the working state, all the gas in the air film 6 is extracted, so that the air film 6 is tightly attached to the surface of the lattice structure floating body 5, which helps to enhance the rigidity of the lattice structure floating body 5 and reduce the degree of structural deformation during operation.

[0025] The supporting inflatable column 7 is inserted into the lattice structure float 5 to improve the stability of the lattice structure float 5. The supporting inflatable column 7 is a cylindrical gas column made of PVC or TPU material. The supporting inflatable column 7 has the same diameter as the hollow rod of the lattice structure float 5. The supporting inflatable column 7 is inserted between the trusses in the lattice structure float 5. In the working state, the supporting inflatable column 7 is filled with gas to expand it, so as to play the role of supporting the lattice structure float 5 and limit the deformation of the lattice structure float 5 in the working state.

[0026] like Figure 5 As shown, the lattice structure floating body 5 is composed of rigid lattice units 8 and flexible connection units 9 arranged alternately, and both units are rod-based structures. The rigid lattice unit 8 is designed based on the lattice structure, and the supporting rods of the rigid lattice unit 8 and the flexible connection unit 9 are both cylindrical straight rods.

[0027] The cylindrical straight rods in the lattice structure float 5 are hollow rods, the thickness of which is 1 / 10-1 / 5 of the length, and are manufactured by 3D printing or one-time casting to ensure the molding quality of the connection between the rigid lattice unit 8 and the flexible connection unit 9. The volume of the filling structure inside the hollow rod does not exceed 40% of the total volume of the hollow rod. The hollow rod has the characteristics of light weight, high strength and better energy absorption effect.

[0028] Each rigid lattice unit 8 is designed with four endpoints in each face of a cube connected diagonally through a rod through the center of the face, and is the main load-bearing unit. The flexible connection unit 9 uses a highly elastic flexible material, and has two main functions: First, the energy absorption and vibration reduction capacity of the lattice structure floating body 5 is improved through the flexible material. Second, when the lattice structure floating module 3 turns from the working state to the contracted state, its high elasticity can be used to realize the curling of the lattice structure floating module 3, realize its rolling and contraction, reduce the volume occupied by the contracted state, and facilitate transportation and storage.

[0029] In order to make the expanded supporting air columns 7 fully support the lattice structure floating body 5 in the working state, each flexible connection unit 9 is inserted with four supporting air columns 7, and four supporting air columns 7 form a group. The air columns have the same diameter as the rods of the lattice structure floating body 5, and the insertion positions are as follows: Figure 6 shown.

[0030] The multi-channel gas management device 4 includes an integrated gas pump 10, a gas connection pipe 11, a shell float 12 and a gas management module. Figure 7 (a) and Figure 7 As shown in (b), the integrated air pump 10, the gas connection pipe 11 and the gas management module are all placed in the outer shell float 12, and connected to the lattice structure floating module 3 through the connection structure 2. After the connection, the outer shell float 12 and the upper surface of the air film 6 are in the same plane, biased towards the paved road.

[0031] The gas connection pipe 11 is divided into two types: the air film connection pipe 13 and the inflatable column connection pipe 14, both of which are used as gas passages between the air film 6 enclosed area, the supporting inflatable column 7 and the integrated air pump 10. Each group of inflatable column connection pipes 14 will be combined into a large connection pipe, which is connected to the integrated air pump 10 in the air film connection pipe 13.

[0032] The integrated air pump 10 performs suction and inflation operations on the air film 6 enclosed area and the supporting air-filled column 7. The integrated air pump 10 has multiple built-in air pumps for absorbing and discharging gas. The gas management module monitors and regulates the air pressure in the air film 6 enclosed area and the supporting air-filled column 7 in real time by setting multiple pressure sensors on the air film 6 and the supporting air-filled column 7.

[0033] The location of the air pressure sensor in the gas management module is as follows: Figure 8 As shown, the square area is the location of the air pressure sensor on the upper and lower supporting air-filled columns 7, which is the geometric center of each rigid lattice unit 8 in the top view. The circular area is the location of the air pressure sensor on the left and right supporting air-filled columns 7, which is the midpoint of the upper right rod of the geometric center of each rigid lattice unit 8 in the top view. The air pressure sensor on the air membrane 6 is set at the contact point between the geometric center of each rigid lattice unit 8 and the air membrane 6.

[0034] A method for using a pneumatic fast floating bridge module based on a rigid-flexible lattice structure comprises the following steps: Step S1, assembling the pneumatic fast floating bridge module unit 1: Step S11, arrange air pressure sensors at predetermined positions in the supporting air-filled columns 7 and the air membranes 6, insert the supporting air-filled columns 7 into the lattice structure floating body 5, wrap the lattice structure floating body 5 with the air membranes 6, and assemble the lattice structure floating module 3.

[0035] Step S12 , connecting the integrated air pump 10 to the lattice structure floating module 3 through the gas connecting pipe 11 , and installing the outer shell floating body 12 to dock with the connecting structure 2 on the air membrane 6 .

[0036] Step S2, contracted storage state: the air in the air film 6 and the supporting inflatable column 7 is continuously extracted through the integrated air pump 10, and at the same time, the lattice structure floating module 3 is rotated and rolled up using the flexible connection unit 9 of the lattice structure float 5, and the pneumatic rapid floating bridge module is turned into a contracted state.

[0037] Step S3, shrinking from storage state to working state.

[0038] Step S31, after placing the pneumatic fast floating bridge module at the designated position, the integrated air pump 10 rapidly inflates the air film 6 enclosed area, so that the lattice structure floating module 3 is rapidly straightened from being rolled up.

[0039] Step S32 , rapidly inflate the supporting air-filled columns 7 to expand them, thereby fixing the shape of the lattice structure floating module 3 .

[0040] Step S33, finally, the closed area of ​​the air film 6 is quickly evacuated so that the air film 6 is tightly attached to the surface of the lattice structure float 5.

[0041] Step S34: finally paving the road on the surface.

[0042] Step S4, working status: When the floating bridge is in working status, the gas management module monitors through the air pressure sensors arranged in the closed area of ​​the air membrane 6 and the supporting inflatable columns 7, so as to adjust the power of the integrated air pump 10 and monitor the working status of the air membrane 6 and the supporting inflatable columns 7 in real time.

[0043] Step S5, assembling the pneumatic fast floating bridge: assembling the pneumatic fast floating bridge module units 1 along various directions according to actual conditions.

[0044] Step S6: From working state to contracted storage state.

[0045] Step S61, releasing the assembly of the pneumatic rapid floating bridge module units 1 and dismantling the road.

[0046] Step S62, after the road is removed, the air membrane 6 is inflated to the enclosed area to atmospheric pressure, the supporting inflatable column 7 is sucked to atmospheric pressure, the lattice structure floating module 3 is shrunk and rolled up, and the multi-channel gas management device 4 is closed.

[0047] Step S63, splitting the lattice structure floating module 3 and the multi-channel gas management device 4 and storing them separately.

[0048] Therefore, the present invention adopts the above-mentioned pneumatic rapid floating bridge module based on the rigid-flexible lattice structure and the use method thereof. Through the rigid-flexible design concept, coupled with the excellent light weight, high strength, and excellent energy absorption and shock absorption characteristics of the lattice structure itself, the rapid switching of the working state and the contraction state of the floating bridge module and the adaptive regulation of the floating bridge module in the working state are achieved in a pneumatic manner, thereby achieving rapid start-up of the floating bridge module and improving the stability of the floating bridge in the working state, thereby realizing a lightweight, excellent energy absorption and shock absorption, fast start-up, and adaptive floating bridge module.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
