Lifting system for multi-wire diamond wire saw

Abstract

The invention belongs to a lifting system for a multi-wire diamond wire saw. The main structure of the lifting system for the multi-rope diamond wire saw comprises a stand, lifting sliding sleeves, a driving motor, screw rods and a string bead wire, wherein the stand is of a door-shaped support structure formed by two stand upright posts and a top beam; auxiliary oil cylinders are arranged between bases of the stand upright posts and the lifting sliding sleeves and are fixedly arranged on the bases; piston rods of the auxiliary oil cylinders are hollow piston rods; inner bores of the piston rods are greater than the outside diameter of the screw rod; the top end of the lifting system is opened; the lower end of a main nut of each lifting sliding sleeve is connected with the top end of the corresponding piston; the upper ends of the screw rods are connected with a driving system of the driving motor; and the lower ends of the screw rods penetrate through the main nuts of the lifting sliding sleeves and extend into inner cavities of the piston rods. According to the lifting system disclosed by the invention, an auxiliary oil cylinder system is additionally arranged for offsetting and balancing the weight and bias torque of the lifting system of a saw machine; and a detection sensor and a rotary coder are additionally arranged, so that automatic shutdown can be realized when the wear of the main nut reaches a dangerous degree and the whole driving system has faults and further accidents are avoided.

Description

technical field [0001] The invention belongs to the field of parts, components or accessories of machine tools, in particular to a lifting system of a multi-rope diamond bead saw. Background technique [0002] Existing multi-rope (usually more than 5) diamond beaded saws are used as heavy machinery for cutting stones. At the beginning of work, the beaded ropes used as the cutting saw should be lifted to the top of the stone, and move down as the cutting progresses. figure 1 As shown, its main structure includes a frame 1, a lifting sliding sleeve 2, a drive motor 3, a screw rod 4, and a beaded rope 5. The frame 1 is composed of two frame columns 11 and a top beam 12 in the shape of a "door". Two screw rods 4 are respectively fixed on the top beam 12 and the frame column base 13, the driving motor 3 drives the screw rod 4 to rotate through the transmission system 31, and the screw rod cooperates with the main nut 21 in the lifting sleeve to drive the lifting The sliding slee...

[0002] Existing multi-rope (usually more than 5) diamond beaded saws are used as heavy machinery for cutting stones. At the beginning of work, the beaded ropes used as the cutting saw should be lifted to the top of the stone, and move down as the cutting progresses. figure 1 As shown, its main structure includes a frame 1, a lifting sliding sleeve 2, a drive motor 3, a screw rod 4, and a beaded rope 5. The frame 1 is composed of two frame columns 11 and a top beam 12 in the shape of a "door". Two screw rods 4 are respectively fixed on the top beam 12 and the frame column base 13, the driving motor 3 drives the screw rod 4 to rotate through the transmission system 31, and the screw rod cooperates with the main nut 21 in the lifting sleeve to drive the lifting The sliding sleeve moves up and down, and the beaded rope 5 is wound on the wheel set of the lifting sliding sleeve. Usually, a multi-rope diamond bead saw with a main motor power of 200KW has a total weight of nearly 20 tons of the lifting sliding sleeve, and is mainly concentrated on the front end. , there is a tendency to lean forward. When this weight directly acts on the main nut of the lifting sleeve, it is easy to generate a bias moment, which deteriorates the working state of the main nut and easily causes damage to the main nut. When the nut cannot withstand the entire set due to excessive wear When lifting the weight of the sliding sleeve, the lifting sliding sleeve may suddenly fall, causing the beaded rope to break, equipment damage, and even personal accidents
