Diamond wire saw

Abstract

The invention relates to a diamond wire saw which comprises a power head, a rotation mechanism, a travelling mechanism, a box body and a control system. A transversely-moving shaft in the power head of the diamond wire saw is placed in a sliding bearing seat of a rotation spindle connecting piece in the rotation mechanism, and a transversely-moving oil cylinder is fixedly arranged in the rotationspindle connecting piece; a hydraulic station controls a piston rod of the transversely-moving oil cylinder to move, and the travelling mechanism comprises a vertical adjusting mechanism in an adjusting chain wheel and a chain track engaged mode; a traveling chain adopts a direct connection mode; a rotation spindle of the diamond wire saw is subjected to double supporting of a double-supporting rotation speed reducer and a rotation spindle bearing seat, and the power head supports force and stably rotates; the power head and a power wheel stably operate, drooping and shaking are avoided even if the power head is used for a long period, during cutting, shaking is small, and machine vibration is also small; transverse movement is achieved in a hydraulic mode, and the parallelism depth errorof movement in the up-down and left-right directions is small; and through the vertical adjusting mechanism, the diamond wire saw normally travels on various tracks, and the climbing ability of the diamond wire saw is improved.

Description

technical field [0001] The invention relates to cutting equipment, in particular to a diamond wire saw machine. Background technique [0002] Diamond wire saw machine is used for cutting and mining marble, granite, sandstone and other stone ores, as well as reinforced concrete, bridges and other cutting and demolition equipment. During operation, the beaded wire saw is worn on the drilled stone, and the wire saw is connected with a joint to form a closed saw ring. The power wheel installed on the main motor drives the wire saw to move in a rapid cycle. The traveling sprocket on the reducer drives the wire saw machine to move backward on the track at a certain speed to cut stone or steel concrete. [0003] Figure 7 It is a diamond wire saw machine in the prior art and a schematic diagram of its use. The diamond wire saw machine is mainly composed of a power head 32 , a rotary mechanism 31 , a traveling mechanism 30 , a track 29 and a wire saw 25 . The traveling mechanism ...

AI Technical Summary

Problems solved by technology

[0006] (1) Most of the sheets are thin. Although some shelves are very large, electric welding or even spot welding is used because the sheets are thin.

[0007] (2) The rotary box that supports the rotation and lateral movement of the power head adopts a single-rotation support reducer. The diameter of the rotary main shaft is only about 140mm, and the power head is easy to sag. The vibration of the big machine is also big. After a period of use, the power head droops seriously, and it is difficult to repair except for replacement;

[0008] (3) The lifting ring is basically welded, if the welding is not firm and there is a false weld, it is easy to cause a safety accident;

[0009] (4) Most of the guide wheels are equipped with ordinary precision bearings. The good ones can be used for half a year, and some can only be used for two to three months or even a month.

[0010] (5) The wire control method is adopted. Most of the control wires use 24-core wires, and some even use 48-core wires. It is difficult to repair if a fault occurs.

[0012] (7) The left and right adjustment of the power head is basically driven by a screw nut. The screw is easy to wear, and if the screw protection is not good and the limit is not effective, it is easy to fail
