Description

{Self-propelled diamond wire saw machine}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled diamond wire saw machine, and more particularly, to a self-propelled diamond wire saw machine used for cutting concrete structures or stones, To prevent splashing and safety of the diamond wire saw, and to easily supply the cooling water supply for reducing the high frictional heat generated at the portion where the diamond wire saw is in contact with the concrete structure.

Generally, when a reinforced concrete structure having a large volume such as a pier of a building or a bridge or a structure generated when a building is demolished is broken, the concrete structure is slightly broken by using an excavator, so that the demolition time is long , Noise and dust are generated to deepen environmental pollution and require a lot of manpower.

Recently, a diamond wire saw machine using diamond wire saw has been widely used to solve the problems of the related art.

A diamond wire saw machine is equipped with a high-hardness diamond tip on a wire, placing the wire saw on an object to be cut, rotating the wire saw while pulling the wire saw, cutting the plane of the object, cutting the object .

The conventional diamond wire saw machine is composed of a drive pulley which is rotated in the normal or reverse direction by driving an engine or a motor on a machine body installed on a guide rail, and a vertical hole or a horizontal hole The diamond wire saw is driven by the drive pulley to rotate the drive pulley, the main body is retracted from the guide rail as the concrete structure is cut, and when the cutting operation is completed, the guide rail is disassembled and the main body is moved repeatedly.

The diamond wire saw has a structure in which a plurality of diamond tips are coupled to an outer circumferential surface of a wire formed by twisting a plurality of steel wires and a connection part is formed between the diamond tips and a sleeve for forming a closed curve.

However, in the above-described diamond wire sawing machine, as described above, since the guide rail is separated and rejoined to change the cutting position and then the main body is moved, it requires a considerable work time and manpower, .

In addition, as the object is cut, the wire saw machine body is pulled back while the wire saw machine body is pulled back, and a relatively large working space is required. In addition, if the wire saw rotating at high speed and high tension during operation is broken, a fatal accident occurs Problems are also pointed out.

A registration utility model 20-0305560 designed to solve this problem includes a running section having an endless track driven by a hydraulic motor directly connected to a planetary gear type speed reducer; An upper frame provided with an engine for turning the hydraulic pump, a fuel tank, a hydraulic pump, and a hydraulic valve; A drive unit mounted on the upper frame and provided with a drive pulley for rotating the wire saw; A plurality of idler rollers for changing the direction of the wire saws coming out of the driving unit; And a guide portion for guiding the movement path of the aileron being rotated by the drive pulley.

Since the self-propelled diamond wire saw machine according to the registration utility model No. 20-0305560 is cut in the equipment while moving the idler roller part on the guide, it is not necessary to repeatedly install and disassemble the guide rails on the floor surface, , The work time is significantly shortened and the number of workers is significantly reduced. Since the size of the equipment is small, the space required for the work is small, and the range of safety accidents caused by the breakage of the wire saw that has taken over long is reduced And it is possible to prevent an accident that the wire saw is cut off due to abrupt load fluctuation which is caused by the wire saw. Further, since there is no need for a separate device for generating power by driving the hydraulic pump by the motor or the engine, the work environment can be improved and the working time can be reduced and the motor can be driven by itself without any additional heavy equipment. It is known.

However, the self-propelled diamond wire saw machine according to the above-mentioned Registration Utility Model No. 20-0305560 has been proposed to prevent dust or the like generated when a concrete structure or stone is cut by diamond wire sawing, In addition, when a diamond wire saw having a high tension is cut, when a wire saw is bounced around, a large impact is applied to a neighboring worker or other equipment, which may cause a safety accident. Diamond wire saws Since the cooling water for reducing the high frictional heat generated at the portion where the concrete structure touches the concrete is supplied through a separate hose and the water supply hose is sprayed by the hand of the operator by hand, .
