Technical Field

[0001] This utility model relates to the field of Bailey bridge technology, specifically a modular Bailey bridge structure that can be quickly assembled and disassembled. Background Technology

[0002] Bailey bridges are a common type of temporary bridge structure, constructed primarily of Bailey beams as load-bearing components. To improve installation efficiency, Bailey beams are typically assembled into components before being connected and assembled together.

[0003] Currently, components are typically connected and fixed with bolts during assembly, which makes installation and subsequent disassembly cumbersome, time-consuming, and reduces overall construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a modular Bailey bridge structure that can be quickly assembled and disassembled, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular Bailey bridge structure that can be quickly assembled and disassembled, comprising: two support frames, the support frames having a C-shaped cross-section; several connecting frames, fixedly disposed between the two support frames, with both ends of the connecting frames inserted into the two support frames respectively, and the connecting frames being perpendicular to the support frames; several stabilizing frames, disposed between the support frames and the connecting frames; several through holes, penetrating the overlapping area between the support frames, connecting frames, and stabilizing frames; a docking sleeve, inserted into the through holes; several elastic shrink plates, fixedly disposed at one end of the docking sleeve; a clamp, fixedly disposed on the end face of the elastic shrink plates, the clamp having a trapezoidal cross-section to facilitate the installation and disassembly of the docking sleeve; a filler core, inserted into the docking sleeve, one end of the filler core extending to the clamp position to limit one end of the docking sleeve; and a tensioning sleeve, threaded on the surface of the docking sleeve, the tensioning sleeve being away from the clamp, the tensioning sleeve being configured to, when rotated, tightly connect the support frames, connecting frames, and stabilizing frames through cooperation with the clamp.

[0006] Preferably, it further includes: a mating block, fixedly disposed at one end of two support frames, the two mating blocks being located on the same side; a circular through hole, penetrating one end of the two mating blocks and the other end of the two support frames, the circular through hole on the mating block and the support frame being connected when the mating block is inserted into the other end of the support frame; a mating bolt, inserted into the circular through hole, the mating bolt penetrating the support frame and the mating block; and a mating nut, threaded onto the mating bolt.

[0007] Preferably, it further includes: a stabilizing block, fixedly disposed at both ends of the connecting frame, the stabilizing block being inserted into the support frame, and the outer surface of the stabilizing block being tightly fitted with the interior of the support frame.

[0008] Preferably, it further includes: a positioning partition, which is fixedly disposed inside the support frame, wherein the side of the positioning partition is in close contact with the surface of the stabilizer frame, and the positioning partition is hollow.

[0009] Preferably, it further includes: a plurality of elastic rubber pads, sleeved on the mating sleeve, wherein the surfaces of the plurality of elastic rubber pads are respectively in close contact with the surfaces of the tensioning screw sleeve, the support frame and the stabilizer.

[0011] This utility model provides a modular Bailey bridge structure that can be quickly assembled and disassembled, which has the following advantages:

[0012] This invention involves passing the docking sleeve through the corresponding docking hole. During installation, the clamp head is compressed and contracts towards the center, causing the elastic shrinkage piece to deform elastically. After the clamp head disengages from the docking hole, the elastic shrinkage piece restores its elastic deformation and expands the clamp head, allowing it to tightly connect the support frame, connecting frame, and / or stabilizing frame together with the tensioning screw sleeve. Then, the filling core is inserted into the docking sleeve to limit the clamp head, completing the rapid assembly of the modular Bailey bridge trestle component. During disassembly, only the filling core needs to be removed from the docking sleeve, and then the docking sleeve can be pulled out, improving construction efficiency. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: Referring to 1-4, in this embodiment, a modular Bailey bridge structure that can be quickly assembled and disassembled includes: two support frames 1, the support frames 1 having a C-shaped cross-section; several connecting frames 2, fixedly disposed between the two support frames 1, with both ends of the connecting frames 2 inserted into the two support frames 1 respectively, and the connecting frames 2 being perpendicular to the support frames 1; several stabilizing frames 3, disposed between the support frames 1 and the connecting frames 2; several through holes 5, penetrating the overlapping area between the support frames 1, connecting frames 2 and stabilizing frames 3; a docking sleeve 6, inserted into the through holes 5; several elastic shrink plates 7, fixedly disposed at one end of the docking sleeve 6; a clamp 8, fixedly disposed on the end face of the elastic shrink plate 7, the clamp 8 having a trapezoidal cross-section to facilitate the installation and disassembly of the docking sleeve 6; and a filling core 9, inserted into the docking sleeve 6. The filling core 9 extends to the position of the clamp 8 at one end, so that one end of the mating sleeve 6 is limited; the tensioning sleeve 10 is threaded on the surface of the mating sleeve 6 and is away from the clamp 8. The tensioning sleeve 10 is set to tightly connect the support frame 1, the connecting frame 2 and the stabilizing frame 3 through cooperation with the clamp 8 when rotating. The connecting frame 2 can form a preliminary frame through cooperation with the support frame 1 and perform basic functions. The stabilizing frame 3 can provide auxiliary support and improve structural strength. The elastic shrink plate 7 can shrink the clamp 8 when it is under pressure, so that it can pass through the mating through hole 5. The filling core 9 can fill the inside of the mating sleeve 6 to improve its structural strength and limit the clamp 8 to improve its tensile strength and improve the connection strength.

[0020] It also includes: a docking block 12, fixedly installed at one end of two support frames 1, with the two docking blocks 12 located on the same side; a circular through hole 13, which is opened through one end of the two docking blocks 12 and the other end of the two support frames 1, and when the docking blocks 12 are inserted into the other end of the support frames 1, the circular through hole 13 on the docking blocks 12 and the support frames 1 are connected; a docking bolt 14, inserted into the circular through hole 13, and the docking bolt 14 passes through the support frame 1 and the docking block 12; and a docking nut 15, threaded onto the docking bolt 14. By setting the docking blocks 12, the two components can be connected together; by setting the docking bolts 14, the position of the docking blocks 12 can be fixed; and by setting the docking nut 15, the docking bolts 14 can be prevented from coming off, thus improving the stability of the connection.

[0021] Stabilizing blocks 4 are fixedly installed at both ends of the connecting frame 2. Stabilizing blocks 4 are inserted into the support frame 1. The outer surface of stabilizing blocks 4 is in close contact with the inside of the support frame 1, which can increase the contact area between the connecting frame 2 and the support frame 1, making the connecting frame 2 less prone to shaking and improving stability.

[0022] It also includes: a positioning partition 16, which is fixedly installed inside the support frame 1. The side of the positioning partition 16 is in close contact with the surface of the stabilizer 3. The positioning partition 16 is hollow and can position the stabilizer 3 so that it is not easy to shake and improve stability.

[0023] It also includes: several elastic rubber pads 11, which are fitted onto the mating sleeve 6. The surfaces of the several elastic rubber pads 11 are in close contact with the surfaces of the tensioning screw sleeve 10, the support frame 1 and the stabilizer 3, respectively, to increase the friction between them and the tensioning screw sleeve 10, making it less prone to loosening.

[0024] The shape formed after several stabilizers 3 are fixed together is rhomboid.

[0025] This utility model provides a modular Bailey bridge structure that can be quickly assembled and disassembled. The specific working principle is as follows:

[0026] When assembling the modular Bailey bridge components, the workers assemble the designated support frame 1, connecting frame 2, and stabilizing frame 3 one by one. After aligning the docking through holes 5 on the components, the workers pass the docking sleeve 6 through the corresponding docking through hole 5. During the installation process, the clamp head 8 is squeezed and shrinks towards the center, causing the elastic shrinkage piece 7 to undergo elastic deformation. When the clamp head 8 is released from the docking through hole 5, the elastic shrinkage piece 7 restores its elastic deformation and opens the clamp head 8, so that it can tightly connect the support frame 1, connecting frame 2, and / or stabilizing frame 3 together with the cooperation of the tensioning sleeve 10. Then, the filling core 9 is inserted into the docking sleeve 6, so that the filling core 9 limits the clamp head 8, completing the installation. When disassembling, it is only necessary to remove the filling core 9 from the docking sleeve 6, and then pull out the docking sleeve 6 to disassemble.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
