A heavy equipment transfer system with curved track transportation

Abstract

The invention relates to a heavy equipment transport system containing curved rail transport. The heavy equipment transport system comprises a heavy rail, a heavy load vehicle and power units; the heavy rail comprises two rails arranged side by side; clamping grooves are formed in the upper surfaces of the two rails; the heavy load vehicle is in sliding fit with the heavy rail; each rail of the heavy rail is matched with one corresponding power unit; each power unit comprises a back seat, a stepping hydraulic cylinder and a hydraulic pump station; each back seat comprises a lower clamping part; the lower clamping parts are in snap fit with the clamping grooves formed in the upper surfaces of the two rails; one end of each stepping hydraulic cylinder is connected with the corresponding back seat; the other end of each stepping hydraulic cylinder is connected with the heavy load vehicle. The hydraulic pump stations are connected with the stepping hydraulic cylinders through pipelines, and therefore the stepping hydraulic cylinders are driven. According to the heavy equipment transport system, the aim that a main device can walk on a curve is achieved; heavy load rollers are arranged at the lower portion of a vehicle frame; the rolling transport mode is adopted, and the needed driving force is small; due to the clamping grooves in the side walls of the two groove-type rails, the number of operators is reduced, and the labor intensity of the operators is relieved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant heavy equipment transfer, in particular to a heavy equipment transfer system with curved track transportation. Background technique [0002] In the current second-generation and second-generation semi-pressurized water reactor nuclear power plants (stations), the transfer system for heavy equipment (that is, main equipment, including reactor pressure vessels, steam generators, and pressurizers, etc.) The transportation from the outside of the plant equipment gate to the designated location in the reactor building is mainly composed of heavy rails, heavy trucks and towing systems. The heavy rails are two parallel straight rails with a rectangular cross-section, and a guide rail with a rectangular cross-section is fixed on the upper surface of one of the rails. The heavy-duty vehicle is composed of front and rear frames, and the two frames are rigidly connected, and are pulled by the to...

AI Technical Summary

Problems solved by technology

The towing system consists of a tractor and a wire rope. One end of the wire rope is connected to the heavy-duty vehicle and the other end is connected to the tractor. This equipment can only complete the transportation of heavy equipment on straight rails.
