Description

Self-propelled wire saw machine {Self Drive Wire saw machine}

The present invention relates to a self propellered wire saw machine, and as the cutting body is cut in more detail, a guide rail for transporting the wire saw machine itself to the rear is removed so that the guide rail does not need to be installed and removed, and the self propellered wire saw machine It is a self-propelled wire saw machine which has an engine and a running part which can be cut without the support of other heavy equipment.

In general, when demolishing a large-volume reinforced concrete structure such as a bridge of a building or a bridge, a demolition work is performed using an excavator.

By using the excavator to open the concrete structure little by little to cut the reinforcement or steel frame installed in the concrete structure using an oxygen cutter. When using this method to dismantle the structure, a long time is used, noise and dust are generated to intensify environmental pollution, and require a lot of manpower. In addition, there was a problem that frequent safety accidents during the demolition work.

In order to solve this problem, a method of dismantling and dismantling the structure by installing explosives on a plurality of bodies of the structure, but this method has a problem that a large amount of dust occurs at a time, the risk of safety accidents due to debris Because of this, a high level of skill is required. In addition, when a single blast does not sufficiently blow up the structure, it may be difficult to dismantle the structure.

In addition, when dismantling overpasses, elevated roads, etc., where the traffic of vehicles is in progress, the long-term work may impede the smooth communication of traffic.

Recently, in order to solve the problems of the related art, a wire saw machine using a wire saw as shown in FIG. 1 has been widely used.

The wire saw machine is a device in which the diamond tip of the wire saw cuts the surface of the object by installing a hard diamond tip on the wire, mounting the wire saw on the object to be cut, and rotating the wire saw while pulling the wire saw. to be.

Accordingly, a wire saw machine according to the prior art will be described with reference to the accompanying drawings.

1 is an enlarged view showing a part of a wire saw used in a general wire saw machine, and FIGS. 2 to 3 are schematic views showing a working state of a wire saw machine according to the prior art.

As shown in FIG. 1, a general wire saw has a plurality of diamond teams 3 coupled to an outer circumferential surface of a wire 2 formed by twisting a plurality of regular lines 2 ′, and a spacing sleeve (between the diamond tips). 4) is connected to the connecting portion (5) to form a closed curve.

2 and 3 illustrate a working state of cutting concrete framework using a wire saw machine.

First, the guide rail 14 is installed and the main body 10 is seated on the guide rail 14. Next, equipment such as a core drill (not shown) is used to drill vertical holes 16 or horizontal holes (not shown) in the concrete framework 18. The wire saw 1 is placed through the vertical hole 16 and then the wire saw 1 is fastened to the driving pulley 12.

Thereafter, as the concrete frame 18 is cut while rotating the driving pulley 12, the main body 10 is retracted on the guide rail 14. When the cutting operation is completed, the guide rail 14 is dismantled and then the body 10 is moved and the above operation is repeated.

The wire saw machine according to the prior art configured as described above is variously used for work such as demolition of buildings and some cutting, cutting of bridges, and the like.

However, in this type of wire saw machine, as described above, the guide rail 14 must be detached and recombined to change the cutting position, and then the main body 10 must be moved.

These tasks require considerable time and manpower, resulting in higher operating costs. In addition, as the object is cut, a relatively large work space is required by pulling the wire saw 1 while the wire saw machine main body 10 moves backward, and the wire saw 1 that rotates at high speed and high tension during operation is broken. In case of loss, the range of fatal accidents is widened.

Accordingly, an object of the present invention is to remove the guide rail for moving the wire saw machine itself in the rear and rail direction as the object is cut, to pull the wire saw using a hydraulic cylinder on the guide provided in the equipment itself, cutting operation It is to provide a self-propelled wire saw machine that all the work is done in one equipment with equipment designed so that the guide rail does not need to be installed and removed. Another object of the invention is to provide a self-propelled wire machine capable of moving and cutting the equipment itself without support by other equipment or withdrawal of power by the power generator.

Still another object of the present invention is to provide a self-propelled wire saw for directly mounting a wire saw in the form of a closed curve without the hassle of mounting the wire saw to the equipment and connecting both ends.

It is yet another object of the present invention to provide a self propellered wire saw machine for facilitating management of storage during and after use by having all the devices necessary for every cut in the equipment.
