Multi-set-rope sawing machine and control method thereof

Abstract

The invention relates to a multi-set-rope sawing machine and a control method thereof. The multi-set-rope sawing machine comprises a gantry rack and a plurality of diamond string bead ropes. The lowerside of the gantry rack is provided with a trolley used for storing stone blocks and capable of longitudinally sliding. A first rack box and a second rack box which are connected through a truss andcan be lifted are arranged on the front portions of the two sides of the gantry rack correspondingly. The first rack box is internally provided with a main driving wheel. The upper portion of the second rack box is provided with a pre-tensioning wheel train assembly. The lower portion of the second rack box is provided with a micro-tensioning wheel train assembly for providing tensioning and supporting. Guiding wheels are further arranged on the inner sides of the lower portions of the first rack box and the second rack box correspondingly. The diamond string bead ropes are wound in wheel grooves corresponding to the main driving wheel, the pre-tensioning wheel train assembly, the micro-tensioning wheel train assembly and a guiding wheel set. The gantry rack is further provided with a water spraying cooling device. The multi-set-rope sawing machine is compact in structure, the purpose of stably cutting a plate can be achieved, and control is convenient.

Description

technical field [0001] The invention relates to a multi-group wire saw machine and a control method thereof. Background technique [0002] Because sand saws, frame saws, and circular saws are machines for cutting stone, they have the main disadvantages of slow cutting speed, large power consumption, unchanged installation, and environmental pollution. The group wire saw machine will become the mainstream stone cutting equipment due to its advantages of fast cutting speed, high efficiency, high power utilization rate and low waste rate. [0003] But the prior art includes various types of multiple sets of wire saw cutting machines, all of which are based on the same principle, wherein an electric motor provides power, which is rotated through a train of wheels and transmitted to a plurality of closed diamond beaded ropes that have been tensioned, and the machine The diamond beaded rope is guided and moderately tensioned. At the same time, the wheel train winding the diamond ...

AI Technical Summary

Problems solved by technology

from figure 1 It can be clearly seen that this type of multi-set saw has a complex structure, many tensioning side wheel sets, and many wearable parts such as bearings, which makes maintenance difficult and costly; Manufacturing and post-maintenance costs; the tensioning part, through the sliding out action, forms a suspended distance ( figure 1 ), tighten the rope, this kind of force is not beneficial, it will affect the stability of the whole machine
