Embodiment Construction

[0037] Such as Figure 1-1 to Figure 13 Shown, the present invention adopts following steps:

[0038] first step, such as Figure 1-1 to Figure 2-2 As shown, make dimension marks on the ground, and place the subgrade platform 1 and subgrade trestle 2 to the set positions;

[0039] The second step, such as image 3 , Figure 4 As shown, the crawler crane 3 is driven to the roadbed platform 1 through the roadbed trestle 2;

[0040] The size and arrangement of the above-mentioned roadbed platform 1 and roadbed trestle 2 are determined according to the size and type of the crawler crane 3 .

[0041] The third step, such as Figure 5 , Image 6 As shown, on the set position of the self-propelled modular transport vehicle 5, several load-sharing pads 4 are placed, and the load-sharing pads 4 are used for crawler cranes 3 with protrusions or depressions on the chassis. The self-propelled modular transport vehicle 5 is evenly stressed;

[0042] The fourth step, such as Figur...

Abstract

The invention provides a process for field shifting and transport of a crawler crane without disassembling and assembling. The process comprises the following steps that S1, a roadbed platform and a roadbed trestle are placed in place; S2, the crawler crane is driven to the roadbed platform; S3, partial loading cushion blocks are placed on a self-propelled modular transport vehicle; S4, the self-propelled modular transport vehicle is driven to the lower part of the crawler crane; S5, the self-propelled modular transport vehicle lifts the crawler crane, the crawler crane is separated from the roadbed platform; S6, the crawler crane is transported by the self-propelled modular transport vehicle to a new construction site; S7, operation of step 1 is repeated; S8, the crawler crane are placedon a roadbed platform of the new construction site; S9, the self-propelled modular transport vehicle is descended and retreated; and S10, the crawler crane is driven to the ground of the new construction site. According to the process, the crawler crane can be integrally transported to the new construction site, the field shifting and transport task of the crane is completed, the transferring field cost of the crawler crane is saved, and the transferring efficiency is improved.

Description

technical field [0001] The invention relates to crawler cranes, in particular to a technology for crawler cranes without dismantling, assembly, and transfer, and belongs to the field of offshore oil engineering. Background technique [0002] At present, crawler cranes are often used in the development and construction of offshore oil projects, especially in the transfer process. However, due to the large tonnage of the crawler crane, the walking is relatively slow, and it is not allowed to walk on public roads during the transfer process. [0003] In order to overcome the above-mentioned shortcomings, the existing method of reversing the yard is to disassemble the crawler crane into several small parts, and use other cranes to hoist and load the car respectively, and then transport it to the new site, unload the car with a crane, and then carry out Overall assembly. The whole process not only has a long construction period, but also consumes manpower and vehicle crane reso...
