Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0019] Please refer to the attached Figure 1 To Attachment Figure 6 The present invention describes an SPMT combined transport lifting beam and a transport method.

[0020] At present, in the early stage of construction of large steel structures in traditional marine engineering, it is necessary to arrange the transport beams at the bottom of the steel structures. When the construction is completed and loaded on the ship, the SPMT self-propelled modular transport vehicle enters the bottom of the transport beams, loads the transport beams and steel structures onto the barge, and the transport beams go out to sea with the steel structures. After the offshore installation is completed, the transport beams return to land with the barge, resulting in a long period of transport beam occupation. A large number of transport beams need to be produced to meet the construction needs of the steel structures on site, which increases the construction cost of the transport beams.

[0021] Therefore, the SPMT combined transport lifting beam includes a foot shoe 2 and two lifting beams 1. The foot shoe 2 is provided with a transport area for carrying the steel structure 3. The lifting beam 1 is provided with an opening 17. The two lifting beams 1 can be buckled together. When the two lifting beams 1 are buckled together, the two openings 17 form a clamping hole, and the clamping hole clamps and fixes the foot shoe 2.

[0022] The SPMT combined transport beam solves the problem that the traditional SPMT roll-on / roll-off loading requires the transport beam 1 to go out to sea with the steel structure 3, and the beam 1 needs to be placed under the structure at the initial stage of construction of the steel structure 3, which leads to a long occupancy period of the transport beam 1. It greatly improves the utilization efficiency of the transport beam 1 and reduces the repeated construction cost of the transport beam 1.

[0023] Furthermore, the lifting beam 1 includes a beam top plate 11, a beam bottom plate 12 and a beam web 13. The beam web 13 is located between the beam top plate 11 and the beam bottom plate 12. The beam top plate 11 and the beam bottom plate 12 are fixedly connected by the beam web 13. When the two lifting beams 1 are buckled, the beam webs 13 of the two lifting beams 1 are in contact with each other, and the foot shoes 2 are in contact with the two beam top plates 11.

By setting the inclined top plate, the amount of steel in the lifting beam 1 is reduced.

[0025] Furthermore, a bolt plate 14 is fixedly connected to the top plate, and bolt holes for bolts to pass through are opened on the bolt plate 14. When the two lifting beams 1 are buckled, the bolt plates 14 on the two lifting beams 1 are in contact, and the two bolt holes overlap. Bolts are passed through the corresponding two bolt holes and then tightened to fix the two lifting beams 1.

[0026] Preferably, the specific number of bolt plates 14 is twelve, and every two bolt plates 14 located on different lifting beams 1 correspond to each other. In other embodiments of the present invention, the specific number of bolt plates 14 is multiple, as long as it can be guaranteed that the lifting beam 1 is fixed when the bolts are tightened.

[0027] Specifically, a beam stiffener plate 16 is fixedly connected between the beam top plate 11 and the beam bottom plate 12 , the beam stiffener plate 16 is fixedly connected to the beam web plate 13 , and the beam stiffener plate 16 is disposed in a direction perpendicular to the beam web plate 13 .

[0028] Furthermore, a lifting lug 15 is fixedly connected to the beam top plate 11, and the lifting lug 15 can be hooked with the hook of the crane. Preferably, the specific number of the lifting lug 15 is four, and each lifting beam 1 is fixedly connected to a lifting lug 15, and the lifting lug 15 is located at both ends of the lifting beam 1.

[0029] Furthermore, the foot shoe 2 includes a shoe top plate 21, a shoe bottom plate 22 and a middle tube 23. The middle tube 23 is fixedly connected to the shoe top plate 21 and the shoe bottom plate 22. The transport area is arranged on the shoe top plate 21. When the two lifting beams 1 are buckled, the clamping hole clamps and fixes the middle tube 23, and the shoe bottom plate 22 contacts the straight top surface, and the shoe bottom plate 22 is supported by the straight top plate.

[0030] Preferably, the diameter of the main column of the steel structure 3 is larger than the diameter of the middle circular hole of the shoe top plate 21 .

[0031] Preferably, the diameter of the intermediate tube 23 is smaller than or equal to the diameter of the clamping hole.

[0032] Preferably, a shoe cross rib plate 25 is fixedly connected inside the middle tube 23 . In other embodiments of the present invention, rib plates of other shapes may also be used as long as the rigid supporting force of the middle tube 23 can be guaranteed.

[0033] Furthermore, a rib plate 24 is fixedly connected between the shoe top plate 21 and the shoe bottom plate 22, and the rib plate 24 is fixedly connected to the middle tube 23. Preferably, the specific number of the rib plates 24 is multiple, and they are equidistantly arranged around the center tube. In other embodiments of the present invention, other numbers of rib plates 24 may be provided, or no rib plates 24 may be provided, as long as the rigid supporting force of the shoe top plate 21 and the shoe bottom plate 22 can be guaranteed.

[0034] Furthermore, a column rib plate 31 is provided on the transport area, and the column rib plate 31 is connected to the shoe top plate 21 and the steel structure 3. By providing the column rib plate 31, the steel structure 3 and the shoe top plate 21 are fixed.

[0035] A SPMT transportation method, using the above-mentioned SPMT combined transportation lifting beam 1, comprises the following steps: S1, place the foot shoe 2 on top of the cement pad 4, weld the rib plate 5 around the middle pipe 23 between the foot shoe 2 and the cement pad 4, place the steel structure 3 in the transportation area of ​​the foot shoe 2, and weld the column rib plate 31 between the steel structure 3 and the foot shoe 2; S2. When loading, the construction rib plate 5 is removed, the hook is connected to the lifting lug 15 by a crane, and the two lifting beams 1 are hoisted on both sides of the middle pipe 23 of the foot shoe 2 in sequence, and insulating rubber is placed between the foot shoe 2 and the transport lifting beam 1. Then, bolts are passed through the two bolt holes and tightened to fix the two lifting beams 1 and clamp and fix the middle pipe 23; S3, the SPMT self-propelled module transporter 6 enters the bottom of the transport beam 1, and places insulating rubber between the transport beam 1 and the SPMT self-propelled module transporter 6. The SPMT self-propelled module transporter 6 rises and contacts the transport beam 1 to transport the steel structure 3 to the barge; S4, after the steel structure 3 falls onto the sea transport pier, the transport lifting beam 1 is hoisted back onto the SPMT self-propelled modular transport vehicle 6, and the transport lifting beam 1 is withdrawn to land along with the SPMT self-propelled modular transport vehicle 6.
