Description

Technical Field

[0001] This utility model relates to the field of transportation technology for large heavy-duty components, specifically a transportation device for cantilever structures. Background Technology

[0002] Self-propelled modular transporters (SPMTs) evolved from hydraulic modular vehicles. They have a large load capacity, are easy to transport, are flexible in steering, and can be modularly combined, which improves the applicability of transporting complex components. They can realize the self-loading and unloading of large and heavy-duty components, have an independent hydraulic suspension system, can overcome complex road conditions, have strong passability, and are widely used in the transportation of large, heavy, and irregularly shaped structures in manufacturing, petroleum, aerospace engineering, nuclear engineering, and bridge engineering.

[0003] During the transport of oversized items, SPMTs (Self-Propelled Modular Vehicles) have lifting capabilities, with a lifting stroke typically exceeding 600mm. When oversized items are placed on supports or platforms, the SPMT can drive under the goods / structures, lift them off the supports or platforms, and then use its own power to move them out of the support or platform position, thus completing the transport of oversized items.

[0004] During the transportation of large items using SPMT modular vehicles, the deployment method of SPMT vehicles and the setting of upper support fixtures are limited due to the influence of road terrain. This results in some structures having large cantilevered sections during transportation, with large negative bending moments at the cantilever roots, which affects structural safety. Utility Model Content

[0005] To address the problem of large negative bending moments caused by large cantilever structures during the transportation of large items, this invention provides a transportation device for cantilever structures. This device can reduce the negative bending moment of the cantilever structure, ensuring that the transported object meets the stress requirements and guarantees structural safety.

[0006] The technical solution adopted by this utility model embodiment to solve its technical problem is:

[0007] A transport device for a cantilever structure includes an SPMT modular vehicle, a first distribution beam, a tower, a cable support structure, and a cable. The tower, the first distribution beam, and the SPMT modular vehicle are arranged sequentially from top to bottom. The cable support structure is fixed to the top of the tower. When the transport device carries the cantilever structure, the main body of the structure can be mounted on the first distribution beam. One end of the cable can be connected and fixed to the cantilever portion of the structure, and the other end of the cable can be connected and fixed to the first distribution beam. The cable is connected to the cable support structure.

[0008] The first distribution beam is a Bailey beam, and the first distribution beam is matched and connected to the SPMT module vehicle at the top and bottom.

[0009] The tower is connected to the first distribution beam via the second distribution beam.

[0010] The second distribution beam is an I-beam frame structure, containing multiple I-beams connected longitudinally and transversely.

[0011] The tower is a frame structure, and its height is greater than that of the structure. Along the length of the SPMT modular vehicle, the tower is located in the middle of the SPMT modular vehicle.

[0012] When the transport device of the cantilever structure carries the structure, the structure is located in front of or behind the SPMT module vehicle, the length direction of the structure is perpendicular or parallel to the length direction of the SPMT module vehicle, and the cable is taut.

[0013] The cable segment between one end of the cable and the cable support structure is the first cable segment, and the cable segment between the other end of the cable and the cable support structure is the second cable segment. The projections of the first cable segment and the second cable segment on the horizontal plane are on the same straight line.

[0014] The second cable section is equipped with a hand-operated hoist, which can adjust the tension of the cable.

[0015] The cable-stayed support structure is either a cable saddle or a truss structure.

[0016] When the transport device of the cantilever structure carries the structure, the structure is connected to the first distribution beam through the second distribution beam. The SPMT module vehicle or the second distribution beam is equipped with a stop block, which is located between the structure and the iron tower. The stop block can prevent the structure from moving towards the iron tower.

[0017] The beneficial effects of this utility model embodiment are:

[0018] 1. It facilitates the rapid transportation and entry / exit of cantilever structures as a whole, reduces on-site cutting or assembly work, enables rapid construction, and thus reduces the disruption to traffic and social impact of construction.

[0019] 2. It is highly adaptable and the arrangement of cable saddles and cables can be adjusted according to the form of the cantilever and the stress.

[0020] 3. Good synchronization: The transported structures and suspension structures are arranged as a whole on the SPMT, and synchronous lifting reduces the risks caused by asynchrony during transportation, making it safer. Attached Figure Description

This utility model is described from the perspective of a reader or user, but the aforementioned directional terms should not be understood or interpreted as limiting the scope of protection of this utility model. Regarding the dimensions and angles of the components, those skilled in the art can determine them specifically based on actual needs or a limited number of experiments.

[0034] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, a transportation device for a cantilever structure includes an SPMT module vehicle 1, a first distribution beam 2, a tower 5, a cable support structure 6, and a cable 7. The tower 5, the first distribution beam 2, and the SPMT module vehicle 1 are arranged sequentially from top to bottom. The weight borne by the tower 5 is transferred to the SPMT module vehicle 1 through the first distribution beam 2. The cable support structure 6 is fixed to the top of the tower 5. When the transportation device for the cantilever structure carries the structure 9, the structure 9 includes a cantilever portion 91 and a main body portion 92. The main body portion 92 can also be called a support structure portion. The main body portion 92 of the structure 9 can be mounted on the first distribution beam 2. One end of the cable 7 can be connected and fixed to the cantilever portion 91 of the structure 9, and the other end of the cable 7 can be connected and fixed to the first distribution beam 2. The cable 7 is connected to the cable support structure 6.

[0035] The first distribution beam 2 is a Bailey bridge beam, which is vertically matched with the SPMT modular vehicle 1. That is, the length and width of the first distribution beam 2 are the same as those of the SPMT modular vehicle 1. The first distribution beam 2 distributes the upper load across the SPMT modular vehicle 1, preventing excessive local load on the frame; simultaneously, the Bailey bridge beam can withstand large bending moments.

[0036] Tower 5 is connected to the first distribution beam 2 via the second distribution beam 3. The second distribution beam 3 is an I-beam frame structure containing multiple I-beams connected longitudinally and transversely. The longitudinal direction can be the length direction of the SPMT module vehicle 1, and the transverse direction can be the width direction of the SPMT module vehicle 1.

[0037] Tower 5 is a frame structure, and its height is greater than that of structure 9; for example, the height of tower 5 is 2 to 5 times the height of structure 9. Along the length of SPMT module vehicle 1 (its direction of travel), tower 5 is located in the middle of SPMT module vehicle 1. The direction of travel of SPMT module vehicle 1 is... Figure 1 The direction from left to right.

[0038] like Figure 1 and Figure 2 As shown, when the transport device of the cantilever structure carries the structure 9, the structure 9 is located in front of or behind the SPMT module vehicle 1, and the length direction of the structure 9 is perpendicular to the length direction of the SPMT module vehicle 1. Alternatively, as... Figure 4 and Figure 5 As shown, the length direction of structure 9 is parallel to the length direction of SPMT module vehicle 1. Cable 7 is in a taut state and is subjected to tensile stress.

[0039] The transport device for the cantilever structure may include one or more SPMT module vehicles 1. When the transport device for the cantilever structure includes multiple SPMT module vehicles 1, the multiple SPMT module vehicles 1 are connected side by side along the width direction of the SPMT module vehicles 1.

[0040] The cable 7 with one end connected to the cable support structure 6 is the first cable segment 71, and the cable 7 with the other end connected to the cable support structure 6 is the second cable segment 72. The projections of the first cable segment 71 and the second cable segment 72 of a cable 7 on the horizontal plane are located on the same straight line.

[0041] The end of the first distribution beam 2 can be connected to the cable 7 to serve as an anchor. The connection between the other end of the cable 7 and the first distribution beam 2 can be located at the upper, middle or lower part of the first distribution beam 2.

[0042] like Figure 1 and Figure 2 As shown, the projection of the first cable segment 71 on the horizontal plane deviates from the length and width directions of the SPMT module vehicle 1, that is, the projection of the first cable segment 71 on the horizontal plane is neither parallel nor perpendicular to the length direction of the SPMT module vehicle 1.

[0043] like Figure 1 and Figure 3 As shown, the cable support structure 6 can serve as a support point, either a cable saddle or a truss structure. When the cable support structure 6 is a cable saddle, the cable 7 passes around the cable saddle. When the cable support structure 6 is a truss structure, the middle part of the cable 7 is connected and fixed to the truss structure. For example, one end of the first cable segment 71 is connected and fixed to the cantilever portion 91 of the structure 9, and the other end of the first cable segment 71 is connected and fixed to the truss structure. One end of the second cable segment 72 is connected and fixed to the truss structure, and the other end of the second cable segment 72 is connected and fixed to the first distribution beam 2.

[0044] A hand-operated hoist 8 can be installed on the second cable section 72. The hand-operated hoist 8 can adjust the tension of the cable 7, that is, the hand-operated hoist 8 can adjust the magnitude of the tensile stress (tension) on the cable 7 to ensure that it will not loosen during transportation.

[0045] The transport device for the cantilever structure may include one or more cables 7. When the transport device for the cantilever structure includes multiple cables 7, one end of the multiple cables 7 may be on the left, right or both sides of the SPMT module vehicle 1.

[0046] When the transport device of the cantilever structure carries the structure 9, the structure 9 is connected to the first distribution beam 2 through the second distribution beam 3. A stop block 4 is fixedly connected to the SPMT module vehicle 1 or the second distribution beam 3. The stop block 4 is located between the structure 9 and the iron tower 5. The stop block 4 can prevent the structure 9 from moving towards the iron tower 5 and prevent the structure 9 from slipping during the transport.

[0047] The following describes the specific usage of the transportation device for the cantilever structure.

[0048] For example, when using SPMT modular vehicle 1 to transport concrete beams (i.e., structure 9), due to site limitations, the vehicle cannot be simply supported at the beam ends. There is a cantilever section 91 at the beam ends, and there is a large negative bending moment at the root of the cantilever section 91. There is a risk of cracking in the upper flange concrete of the beam section.

[0049] During transportation, two sets of SPMT modular vehicles 1 (SPMT modular vehicle 11 and SPMT modular vehicle 12) are respectively arranged at both ends of structure 9. SPMT modular vehicle 11 contains four SPMT modular vehicles 1 arranged side by side, and SPMT modular vehicle 12 contains two SPMT modular vehicles 1 arranged side by side. SPMT modular vehicle 12 and SPMT modular vehicle 11 are spaced apart on the left and right. The two sets of SPMT modular vehicles 1 are located on road 10.

[0050] Structure 9 has a large cantilever at train set #1, meaning the cantilever portion 91 of the transported structure 9 is located on the right side of SPMT module train #11. A first distribution beam 2 is installed and fixed on SPMT module train #11, and a tower 5 is installed on the first distribution beam 2 as a support point for arranging cable support structure 6. Cables 7 are connected to the cantilever portion 91 of the transported structure 9 via cable support structure 6 (cable saddle), and the tension of the cables is adjusted by a hand-operated hoist 8 to ensure that they do not loosen during transportation. The connection between the cables 7 and the cantilever portion 91 can be achieved using existing bolt connections. Second distribution beams 3 are respectively installed between the tower 5, the main body portion 92 of the transported structure 9, and the first distribution beam 2. A stop block 4 is installed next to the main body portion 92 of the transported structure 9 to prevent slippage. It can be understood that the transportation device for the cantilever structure includes SPMT module train #11, the first distribution beam 2, the tower 5, the cable support structure 6, and the cables 7.

[0051] The above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of its implementation. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this utility model should still fall within its coverage. Furthermore, the technical features, technical solutions, and embodiments of this utility model can be freely combined and used.
