Abstract

The invention relates to a tensioning device of an underwater diamond wire sawing machine. The tensioning device comprises a bracket, a tension pulley and a tensioning mechanism which is mounted on the bracket, and is characterized in that the tensioning mechanism comprises a support seat, a fixing disc and a driving disc are coaxially arranged in the internal cavity of the bracket, the fixing disc is fixedly connected with the bracket, a driving shaft penetrates through the center hole of the fixing disc and is connected with one end of the driving disc, the other end of the driving disc penetrates through the support seat and is connected with a tension pulley seat, two permanent magnets are respectively arranged on opposite end faces of the fixing disc and the driving disc, when the driving disc rotates under the drive of the driving shaft, the two magnets generate a repulsion force and an attraction force, the driving disc moves forwards and backwards relative to the fixing disc, and the tension pulley seat is driven to move forwards and backwards, so that the tension pulley moves leftwards and rightwards, and the tension regulation on a beaded rope is realized. According to the tensioning device, due to the adoption of the magnetic tensioning mechanism, the energy loss resulting from friction does not exist, and the vibration and noise can be reduced greatly, so that the tensioning device has the advantages of long part service life, lubricating oil saving and rapidity in regulation.

Description

technical field [0001] The invention relates to the technical field of underwater diamond wire saw machines, in particular to a tensioning device for diamond wire saw machines. Background technique [0002] At present, in the field of cutting and processing of stone and submarine oil pipes, wire saw cutting machines have been widely used due to their own advantages. For the commonly used diamond wire saw machine, it usually includes a clamping mechanism and a cutting mechanism, wherein the cutting mechanism includes a cutting frame, a tensioning device, a main moving device, a radial feeding device and a guiding device, etc. The existing tensioning device is mainly composed of a tensioning wheel, a tensioning wheel shaft seat, an adjustment handle, a screw, and a base. The base is slidingly fitted with the tensioning wheel shaft seat. Pass through the tensioning wheel shaft seat to connect the adjustment handle, and the tensioning wheel shaft seat is provided with a tension...
