Example Embodiment

[0033] like figure 1 As shown, the pipe end cutting device for large-diameter long pipe fittings of the present invention includes a fixed pipe fitting support seat 4, two sections of rails 5 relatively arranged on both sides of the fixed pipe fitting support seat 4, and two sections of rails 5 relatively arranged on And by being positioned at the one end that is positioned at fixed pipe fitting support seat 4 side to the other end, two pipe fittings supporting positioning car 3, two moving receiving cars 2 and two pipe end intersecting line cutting machines 1 are arranged successively. The two mobile receiving vehicles, the two pipe fitting support positioning vehicles and the two pipe end intersecting wire cutting machines can all move and adjust their positions on the track. It can complete the intersecting line cutting of pipes of different lengths and diameters.

[0034] like Figure 2A , 2B , shown in 2C, mobile receiving car 2 is provided with a frame-type car body 2...

Abstract

A large-diameter long-pipe-fitting pipe-end cutting device comprises a pipe-fitting fixing supporting seat, two rails, two pipe-fitting supporting locating trolleys, two moving material connecting trolleys and two pipe-end intersecting line cutting machines, wherein the two rails are oppositely arranged on the two sides of the pipe-fitting fixing supporting seat, and the two pipe-fitting supporting locating trolleys are oppositely arranged on the two rails and are successively arranged at one end of the side of the pipe-fitting fixing supporting seat to the other end of the side of the pipe-fitting fixing supporting seat. The two moving material connecting trolleys, the two pipe-fitting supporting locating trolleys and the two pipe-end intersecting line cutting machines can be moved on the rails so that the positions can be adjusted. The two pipe-fitting supporting locating trolleys have multi-direction moving and adjusting functions, so that the whole device can complete intersecting line cutting work of pipes with different lengths and different pipe diameters.

Description

technical field [0001] The invention relates to a cutting device for pipe ends, in particular to a pipe end cutting device for large-diameter long pipes in marine engineering. Background technique [0002] At present, the existing pipe cutting machines in China mainly have two types: chuck type and friction wheel type, which are used to cut the intersecting lines of pipes with a length of less than 12m and a diameter of less than Φ1.5m: (1) Chuck type pipe cutting Machine: scope of application: small diameter (<670mm), short pipe (<12000mm). Pipe clamping and leveling are time-consuming, the efficiency is not high, and the remaining material after cutting is long. Affected by the bending of the pipe, affected by the longitudinal seam of the welded pipe. It is suitable for general building steel structures. (2) Friction wheel pipe cutting machine: applicable scope diameter (<1500mm), short pipe (<12000mm). The cutting assembly line with automatic transmission ...
