Description

Technical Field

[0001] This application relates to the technical field of ship transportation, and particularly to a fastening connection device and method applicable to pontoon bridge equipment and floating box structures. Background Art

[0002] From the perspective of equipment transportation safety, pontoon bridge equipment and floating box structures need to limit their lateral, longitudinal, and vertical displacements. When the pontoon bridge equipment is in land mobility, its transport vehicle integrates functions such as folding of the pontoon bridge unit (the process of the pontoon bridge unit from the open through-loading state to the folded storage and transportation state), loading, and flooding (the process of the pontoon bridge unit transferring from the transport vehicle to the water). If the traditional fixed rope method is used, its disassembly is time-consuming. This is an unacceptable fixing method for pontoon bridges that need to meet rapid flooding. Therefore, a reliable and easily disassembled fixing method is required for pontoon bridge equipment and floating box structures.

[0003] The fixation of existing pontoon bridge equipment and floating box structures usually adopts two methods. One is the use of ropes and corresponding fixing fixtures in combination, such as the combination of steel wire ropes and wire rope clips, the combination of steel wire ropes and turnbuckles, the combination of fastening belts and ratchet fixing devices, etc. The other is the traditional non-reversible fastening tool with a collar.

[0004] The method using ropes and corresponding fixing fixtures has the disadvantages of large disassembly workload and high labor intensity for personnel when dealing with relatively large pontoon bridge units.

[0005] For the traditional collar method, since the collar cannot be reversed, the collar needs to be removed after the screw is completely withdrawn to release the fixation, resulting in a long disassembly operation time. Summary of the Invention

The collar 2 can be sleeved on the set screw knob 1, and the collar 2 is hinged to the connecting nut 5. The set tool backing plate 7 is provided with a connecting hole 14, asFigure 10 and Figure 11 As shown in Figure 11 , the first end of the screw rod 6 is rotatably connected to the set screw backing plate 7 through the connection hole 14, and the second end of the screw rod 6 is threadedly connected to the connection nut 5.

[0045] In some alternative embodiments, such as Figure 5 and Figure 6 As shown in Figure 6 , hinge shafts 12 are provided on both sides of the connection nut 5. As Figure 3 and Figure 4 As shown in Figure 4 , the collar 2 includes a main ring 9, a reinforcing iron 10 and a lug 11.

[0046] One side of the main ring 9 is arc-shaped, the reinforcing iron 10 is arranged on the inner arc-shaped side of the main ring 9, the other side is connected to the lug 11, and the lug 11 is provided with a through hole 13.

[0047] The collar 2 is hinged to the connection nut 5, including: the lug 11 is sleeved on the hinge shaft 12 through the through hole 13.

[0048] In some alternative embodiments, such as Figure 1 and Figure 2 As shown in Figure 2 , the collar 2 is hinged to the connection nut 5, and further includes: being sleeved on the hinge shaft 12 through the nut 3 and the gasket 4, and abutting against the lug 11 to limit the displacement of the lug 11 in the axial direction of the hinge shaft 12.

[0049] In some alternative embodiments, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown in Figure 11 , the above-mentioned set screw connection device applicable to the floating bridge equipment and floating box structures further includes: a handle 8, which is connected to the first end of the screw rod 6, and rotating the handle 8 can drive the screw rod 6 to rotate.

[0050] In some alternative embodiments, such as Figure 7 and Figure 8 As shown in Figure 8 , a spherical surface assembly 15 is provided at the end of the first end of the screw rod 6. As Figure 10 and Figure 11 As shown in Figure 11 , the connection hole 14 of the set screw backing plate 7 includes a flared opening 16 opened downward, and the flared opening 16 fits with the spherical surface assembly 15.

[0051] In some alternative embodiments, such as Figure 12 and Figure 13 As shown in Figure 13 , a limiting groove 17 is provided at one end of the set screw button 1, the limiting groove is used to sleeve the collar 2, and a welding surface 18 is provided on at least one side of the other end for connecting with the surface of the object to be fixed 22.

[0052] The embodiment of the present application provides a fastening connection method applicable to pontoon bridge equipment and floating box - like structures. By using the fastening connection appliance applicable to pontoon bridge equipment and floating box - like structures in any of the above - mentioned embodiments, the method includes: aligning the fastening round button 1 on the object to be fixed 22 with the fastener on the carrying platform 21 in the longitudinal position. After placing it well on the carrying platform 21; flipping the collar 2 upwards and sleeving the collar 2 on the fastening round button 1; rotating the screw 6 in the first direction to drive the collar 2 and the connecting nut 5 to move downward as a whole, so that the collar 2 presses tightly against the fastening round button 1, thereby forming a firm connection between the object to be fixed and the carrying platform.

[0053] Here, the first direction can be the clockwise or counter - clockwise direction, which can be determined according to the thread directions of the screw 6 and the connecting nut 5. Here, the rotation direction that can drive the connecting nut 5 to move downward along the axial direction of the screw 6 is taken as the first direction. Correspondingly, the direction opposite to the first direction is the second direction. It can be understood that the up and down in the embodiment of the present application are referenced with the carrying platform 21 as the horizontal plane.

[0054] Since hinge shafts 12 are designed on both sides of the connecting nut 5, the collar 2 can be flipped in the vertical plane. Therefore, the object to be fixed 22, such as a pontoon bridge unit, and the carrying platform 21, such as a carrier vehicle, do not need to be precisely aligned in the lateral position. Flipping the collar 2 upwards can buckle it into the fastening round button, improving the operation efficiency. Due to the existence of the fastener backing plate 7, during the process of screwing in the screw 6, the screw 6 cannot move upwards. Therefore, the collar 2 and the connecting nut 4 will move downward as a whole. The collar 2 presses tightly against the fastening round button 1, thereby forming a firm connection between the entire object to be fixed 22 and the carrying platform 21.

[0055] In some alternative embodiments, the above - mentioned method further includes: rotating the screw 6 in the second direction to drive the collar 2 and the connecting nut 5 to move upwards as a whole until the collar 2 can be flipped; flipping the collar 2 downwards so that the collar 2 disengages from the fastening round button 1, thereby releasing the firm connection between the object to be fixed 22 and the carrying platform 21. When the object to be fixed 22 and the carrying platform 21 need to be disconnected, unscrewing the screw 6 in the reverse direction by a certain height space so that the collar 2 can be flipped outwards to complete the disconnection action, without waiting for the screw 6 to be completely withdrawn, thus shortening the operation time.

[0056] In some embodiments, such as Figure 1 and Figure 2As shown in the figure, the fastening connection device consists of a fastening round button 1 (welded and installed on the object to be fixed 22), a collar 2, a nut 3, a washer 4, a connecting nut 5, a screw 6, a fastening device backing plate 7, and a handle 8. During operation, rotate the handle 8 to be perpendicular to the screw 6 for better force application. Rotate the handle 8 counterclockwise to withdraw the screw 6 from the connecting nut 5 by a certain length, thereby increasing the vertical movement space of the collar 2. Flip the collar 2 upward and hook it onto the fastening round button 1 of the object to be fixed 22. At this time, rotate the handle 8 clockwise to drive the screw 6 to screw into the connecting nut 5, and then press and fasten tightly between the collar 2 and the fastening round button 1 to complete the fastening process of the object to be fixed. The disassembly process of the fastening connection device is carried out in the reverse order of the connection process.

[0057] The fastening connection device and method for pontoon bridge equipment and pontoon-like structures provided in the above embodiments of the present application are used to solve the fastening problem of pontoon bridge units on transport vehicles, and have the characteristics of reliable fastening, simple operation, and high operation efficiency; the working mode of the collar is to achieve rotation and internal and external flipping through hinge joints, which can effectively shorten the time for releasing the fixation operation and improve efficiency; the longitudinal movement of the connecting nut is realized through the threaded connection of the screw, which can achieve good fastening effects, and can be directly operated by manpower with relatively low force requirements for operation, reducing the labor intensity of manual work; the spherical surface of the fitting surface at the second end of the screw is in contact with the fastening device backing plate, and at the same time, the fastening device backing plate has a flared hole. After the screw is loosened, the screw, the connecting nut, and the collar can be tilted outward as a whole, facilitating the better detachment of the fastening device from the fastening round button, thereby shortening the time for releasing the fixation operation; it is applicable to the fastening of pontoon bridge equipment and pontoon-like structures of different scales and types.
