Tensioning device for rope saw machine

Abstract

The tightener for rope saw machine includes a seat holding rolling bearing set on tightened saw bow base, one sliding bearing seat holding sliding bearing set on tightened saw bow base, a lead screw with one end set inside the sliding bearing and the other end extending beyond the rolling bearing seat, and one tightening wheel frame set around the lead screw with nut for connection and driving in between. The tightening wheel frame has its top set inside the runner on tightened saw bow base and bottom with wheel for the bead rope to be wound on. The present invention regulates the tightening state of the bead rope indirectly through the feeding of the rope saw machine, and this maintains the stable tightening force during cutting.

Description

technical field [0001] The invention relates to a tensioning device, in particular to a tensioning device of a wire saw machine which can be applied underwater and meets the tension requirement of the wire saw machine for the beaded rope. Background technique [0002] Now, diamond wire saw machines are mainly used in the fields of marble mining, block shaping and segmentation, and special-shaped stone processing. These are all processed on land, so the tensioning device is also used on land. At present, there is still There are no tensioning devices suitable for underwater application. However, with the development of underwater resources, especially the development of offshore oil, in some occasions (such as submarine oil and gas pipeline maintenance operations), it is also necessary to use diamond wire saws underwater. [0003] When the diamond beaded rope cuts the workpiece, there must be a certain pre-tightening force. Only under the action of a suitable tension, the be...

AI Technical Summary

Problems solved by technology

During the cutting process, if the tension force is too small, the friction force is small, the cutting efficiency is low, and even cutting cannot be performed; if the tension force is too large, the life of the beaded rope will be short, and the shaft and bearing will be stressed. The rope will break

[0004] Restricted by the subsea working environment, the size and shape of the cut material, and the cut material, it is necessary to adjust the tension force of the beaded rope according to the working conditions and requirements, and the tensioning devices currently used on land are not suitable Applied underwater, therefore, it is necessary to have a tensioning device that can be applied underwater and meet the tension requirements of the wire saw machine for the beaded rope.
