Embodiment Construction

[0020] Attached below figure 1 And attached figure 2 , the present invention is described in detail.

[0021] An underwater reciprocating cutting saw, comprising a hydraulic clamping mechanism (6), a mechanical structure that enables the saw blade to reciprocate laterally for cutting and longitudinal feeding, a cam mechanism that can realize return lift, and a hydraulic control system that can realize return stop. The above-mentioned hydraulic clamping mechanism (6) can fix the reciprocating cutting saw on the pipe to be cut.

[0022] The mechanical structure that makes the saw blade reciprocate laterally for cutting and longitudinal feeding includes a main body (8), a front panel (7), a horizontal guide column (4), and a longitudinal guide column (5). The front panel (7) and The main body (8) is connected through the horizontal guide column (4), the saw blade (13) is fixed on the front panel (7), and two connecting blocks are connected at both ends by self-made screws, whe...

Abstract

The invention provides an underwater reciprocating cutting saw. The underwater reciprocating cutting saw comprises a hydraulic clamping mechanism, a mechanical structure for enabling a saw blade to perform a transverse reciprocating motion for cutting and longitudinal feeding, a cam mechanism capable of realizing return hoisting, and a hydraulic control system for realizing return stop. The cutting saw is a portable pipe cutting machine, is simple and compact in structure and high in practicability, adopts a cold cutting process, is wide in pipe diameter cutting range and wide in application range, can cut pipes and solid materials (rods and guide rails), can control the cutting speed, is convenient to install and operate, high in automation degree, suitable for ROV operation, not limitedto influence from the water depth, not limited by the environment, smooth in incision surface and high in operation efficiency, achieves the return hoisting function, and greatly prolongs the servicelife of the saw blade.

Description

technical field [0001] The invention relates to a cutting device, in particular to an underwater reciprocating cutting device. Background technique [0002] Under the long-term use of petroleum pipelines, in the face of complex application conditions and transmission medium conditions, oil and gas pipelines, petrochemical pipelines, heating pipelines, etc. often rupture, which not only causes huge economic losses, but also brings serious pollution to the surrounding environment . Therefore, the high-tech demand for corresponding pipeline repair projects is increasing day by day. [0003] This patent proposes an underwater reciprocating cutting saw just under this background. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the invention proposes an underwater reciprocating cutting saw. [0005] The present invention is achieved by the following technical solutions: [0006] An underwater reciprocating cutting saw, characterized in that it...
