DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] As attached Figures 1 to 4A transport rack suitable for large assemblies shown in the figure includes a base plate 1, which has a frame structure. The base plate 1 is a frame formed by welding 60*60*6 square tubes. The square tubes have a large bending section modulus, which means that under the same load, it has high bending strength and performs well in flexibility and time and labor saving. It is more convenient during installation and does not require complicated welding technology. The inside of the base plate 1 is connected with a cross bar 2, and the cross bar 2 is provided with several groups, and each group of cross bars 2 is evenly arranged along the internal horizontal direction of the base plate 1. The cross bar 2 is located in the middle position of the base plate of the transport rack to improve the uniformity and stability of the support. Its size needs to be designed according to the length of the base plate and the weight of the goods carried to ensure sufficient strength and rigidity. A support structure 3 is arranged above the cross bar 2. The support structure 3 is an oblique triangular structure formed by welding square tubes, which can effectively resist the lateral force generated during transportation. If this force is not offset in time, it may cause the component to shift or even overturn during transportation. Through the support setting of the oblique square tubes, these forces are effectively transmitted to the main structure of the transport rack, thereby protecting the stable position of the goods. There are two groups of support structures 3, and multiple groups can be placed at the same time. There are connected gaps in the welded support structures 3 that can laterally load large components, which rationalizes the use of space. The two groups of support structures 3 are evenly arranged along the horizontal direction of the base plate 1, and the two sides of the support structure 3 A raft 4 is provided. The raft 4 is a plate made of Q355B steel, which plays a role in stably setting the bottom of the component on the transport frame. Columns 5 are provided at both corners of one side of the bottom plate 1. The tops of the two groups of columns 5 are connected with beams 6. The supporting body is formed by welding to maintain the overall shape and rigidity of the transport frame. The columns 5 are distributed at the four corners of the base to provide vertical support. The beams 6 are connected to the columns 5 to enhance the stability of the overall structure. One side of the two groups of columns 5 is connected with a guardrail 7. The guardrail 7 provides additional protection for the transport frame to prevent the goods from accidentally falling. One side of the two groups of guardrails 7 is connected with a limit railing 8. When the large component is hoisted to the specified position and fastened with a strap, the limit railing 8 can limit the forward and backward displacement of the component to ensure the transportation safety of the large component. Example 2

[0024] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0025] As a preferred embodiment, the support structure 3 includes a support frame 9 and a longitudinal connecting rod 10. There are three groups of support frames 9, and the three groups of support frames 9 are evenly arranged in the horizontal direction of the base plate 1. The tops of the three groups of support frames 9 are connected with longitudinal connecting rods 10. Such a design can make the supporting force of the transport frame on large components more uniform.

[0026] As a preferred embodiment, the support frame 9 includes a shear column 11 and a cross-link 12. The shear column 11 is a triangular structure and is provided in two groups. The two groups of shear columns 11 are symmetrically arranged along the horizontal direction of the cross bar 2. The shear column 11 is made of a 60*60*6 Q355B steel square tube. For large components with a high center of gravity, the oblique shear column 11 provides a stable base point to help disperse the weight and lower the center of gravity. This improvement in balance is a key factor in ensuring transportation safety, especially when large components need to be moved over long distances. It reduces load concentration at any point and avoids structural damage that may be caused by excessive pressure on a single point. A cross-link 12 is connected to the center of one side of the shear column 11. The cross-link 12 makes each group of shear columns 11 form a complete whole, making the bearing surface of the support frame more stable, and the two groups of shear columns 11 form the support frame 9 through the cross-link 12.

[0027] As a preferred embodiment, several groups of raft plates 4 are provided, and each group of raft plates 4 is arranged in the middle of both sides of two groups of cross bars 2 to form a plane for placing components, which can provide sufficient and uniform support area for large components and avoid structural deformation or damage caused by excessive local force. The surface of the raft plates 4 usually has an anti-slip texture or coating, which can effectively prevent the goods from sliding or shifting during transportation.

[0028] As a preferred embodiment, several groups of inclined beams 13 are obliquely arranged inside the cross beam 6, the guardrail 7 and the limit railing 8. The inclined beams 13 mainly bear axial pressure or tension in the structure. Their function is to provide stability and prevent lateral displacement or twisting of the transport frame during lifting and displacement, thereby ensuring the stability of the above structure.

[0029] As a preferred embodiment, a triangular connecting plate 14 is provided at the connection between the column 5 and the guardrail 7. The triangular connecting plate 14 is located at the corner of the structure. Due to the concentrated force, stress concentration is prone to occur, resulting in material fatigue or fracture. The triangular connecting plate 14 effectively disperses these stresses by providing additional materials and welds, significantly improving the bearing capacity and deformation resistance of the corners, and at the same time helps to prevent the expansion of existing small cracks. Under dynamic or variable loads, cracks are particularly prone to generation and expansion at the corners, and the reinforcement effect of the triangular connecting plate 14 can effectively delay this process.

[0030] As a preferred embodiment, the tops of the crossbeam 6 and the guardrail 7 are both provided with lifting rings 15, which are made of 306X581 Q355B steel. Measures to reduce wear and prevent cracks should be considered during the use of the lifting rings 15, such as adding lubricants or using wear-resistant materials, as well as regular maintenance and inspection procedures to ensure long-term safe use. The maximum load capacity of each set of lifting rings 15 should be clearly marked so that users can clearly understand its scope of application to avoid safety accidents caused by overloading. Four sets of lifting rings 15 are provided, two sets of lifting rings 15 are evenly arranged in the horizontal direction along the top of the crossbeam 6, and the remaining two sets of lifting rings 15 are respectively arranged on the two sets of guardrails 7 to ensure uniform force during lifting to prevent rollover.

[0031] The working process of the utility model is as follows: first, a 60*60*6 square tube is welded into a base plate 1, and then the square tube is used to weld a supporting structure 3, a column 5, a protective railing 7 and a limit railing 8 on the base plate 1 according to the size of the component to be transported to ensure the stability of transportation, and then the large component is hoisted to the specified position and loaded on the base plate 1, and the component is fixed on the supporting structure 3 by a strap, and the bottom of the component is placed on the raft 4 to prevent damage to the edge, and then the transport rack is sent into the container for transportation as a whole. The above is the working principle of a transport rack suitable for large assemblies.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
