A process for transporting a crawler crane without disassembling and splicing in a transition place comprises the following steps: firstly, putting a roadbed platform and a roadbed trestle in place; secondly, driving the crawler crane to the roadbed platform; thirdly, placing a load-sharing cushion block on the self-propelled modular transport vehicle; fourthly, the self-propelled modular transport vehicle is driven to the lower part of the crawler crane; fifthly, lifting the crawler crane by the self-propelled modular transport vehicle roof and separating the crawler crane from the roadbed platform; sixthly, carrying the crawler crane by the self-propelled modular transport vehicle to carry out transition transportation to a new construction site; seventhly, repeating the operation of one; eighthly, placing the crawler crane on a roadbed platform of a new construction site; ninthly, descending the self-propelled modular transport vehicle and withdrawing; and ten, driving the crawler crane to the ground of the new construction site. The crawler crane can be integrally transported to a new construction site, the transition and transportation tasks of the crane are completed, the transition cost of the crawler crane is saved, and the transition efficiency is improved.

Description

Disassembling-free splicing transfer and transportation process for crawler crane

Technical Field

The invention relates to a crawler crane, in particular to a disassembling-free assembling transfer and transportation process of the crawler crane, belonging to the field of marine petroleum engineering.

Background

At present, a crawler crane is often used in the development and construction process of marine petroleum engineering, particularly in the transition transportation process. However, the crawler crane has large tonnage, so that the crawler crane can walk slowly and cannot walk on public roads in the transition transportation process.

In order to overcome the defects, the conventional method for transferring the crawler crane to the field is to disassemble the crawler crane into a plurality of small parts, respectively use other cranes to hoist and load the small parts, transport the small parts to a new construction site, unload the small parts by using the cranes, and integrally assemble the small parts. The whole process is long in construction period, consumes manpower and vehicle crane resources, and the cost of the crawler crane in the transition transportation process is high.

Disclosure of Invention

The invention mainly aims to overcome the defects in the prior art, and provides a disassembling-free assembling, transferring and transporting process of a crawler crane, which not only solves the problems of the crawler crane in the transferring and transporting process, but also greatly shortens the transferring construction period of the crawler crane and improves the transferring efficiency; and under the condition that the crawler crane is not disassembled, the whole crawler crane is transported to a new construction site, the transition and transportation task of the crawler crane is completed, and the transition cost of the crawler crane is greatly saved.

The purpose of the invention is realized by the following technical scheme:

the process for transporting the crawler crane in the disassembly-free assembly transfer field is characterized in that: the method comprises the following steps:

firstly, making size marks on the ground, and placing a roadbed platform and a roadbed trestle at set positions;

secondly, driving the crawler crane to the roadbed platform;

thirdly, placing a plurality of load sharing cushion blocks at set positions of the self-propelled modular transport vehicle;

fourthly, driving the self-propelled modular transport vehicle to a preset position below the crawler crane;

fifthly, lifting the crawler crane by the self-propelled modular transport vehicle roof to separate the crawler crane from the roadbed platform;

sixthly, carrying the crawler crane by the self-propelled modular transport vehicle to carry out transition transportation to a new construction site;

seventhly, repeating the operation of the first step, and placing a roadbed platform and a roadbed trestle on a new construction site;

eighthly, placing the crawler crane on a roadbed platform of a new construction site by using the self-propelled modular transport vehicle;

the ninth step, the self-propelled modular transport vehicle is descended and withdrawn;

and tenth, driving the crawler crane to the ground of the new construction site.

In the second step, the crawler crane runs through the roadbed trestle and goes up and down the roadbed platform.

And in the tenth step, the crawler crane runs through the roadbed trestle.

The invention has the beneficial effects that: by adopting the technical scheme, the transition construction period of the crawler crane is greatly shortened, and the transition efficiency is improved; and under the condition that the crawler crane is not disassembled, the whole crawler crane is transported to a new construction site, the transition and transportation task of the crawler crane is completed, and the transition cost of the crawler crane is greatly saved.
