Production-line ground conveying pre-jacking system and load control method thereof

Abstract

The invention relates to the technical field of ship sectioned transportation and discloses a production-line ground conveying pre-jacking system and a load control method thereof. The system comprises an oil cylinder, a pressure sensor, a servo valve and a reversing valve. The pressure sensor is fixedly mounted in a rodless cavity of the oil cylinder; an oil outlet of a rod cavity of the oil cylinder communicates with an oil inlet of one end of the reversing valve; and an oil inlet of the other end of the reversing valve communicates with an oil outlet of the servo valve. A plurality of ground conveying trolleys which are distributed at the bottom of a product are set in a no-load jacking state, when the pressure reaches a pre-set pressure value of 2MPa, the servo valve is automatically closed, and the oil cylinder stops pre-jacking action. Before product jacking, the system provides pre-jacking for the product, full contact of a balance support and the bottom surface of the product is guaranteed, the good synchronous foundation is built for subsequent synchronous loaded jacking, the advantages of being convenient to control and good in extendibility, and the working efficiency and the operation safety of ship sectioned transportation are greatly improved.

Description

technical field [0001] The invention relates to the technical field of segmental transportation of ships or marine products in the production line of a workshop, especially in the ground transportation trolley system moving between different carriers, specifically a pre-lifting system for ground transportation of a production line and Its load control method. Background technique [0002] In recent years, the shipbuilding industry has overcome difficulties in response to the current situation, breaking through the design and construction technology of luxury cruise ships, and the assembly and construction of cruise ships has been vigorously developed in my country. The thin-plate plane segment assembly line is a production workshop for building luxury cruise ship thin-plate plane segments, including steel pretreatment workshops, plate cutting workshops, profile processing workshops, component manufacturing workshops, and segmental manufacturing workshops where equipment is l...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the control process of the existing ships or marine products in the workshop production line, the ground conveyance trolley and ship segmental movement, the present invention provides a production line ground conveyance pre-jacking system and its load control The method has the advantages of synchronous jacking to prevent the product from tilting and ensure the non-destructiveness of the product, and solves the problems raised in the above-mentioned background technology
