切削用ケーブルによつて切断される。 On the other hand, the present inventor has recently developed a cable drive pulley that circulates a cutting cable, a pulley drive mechanism that rotates the cable, and a pulley drive mechanism that rotates the cable, and a pulley drive mechanism that rotates the cable and rotates it along a parallel track. We are developing a vehicle equipped with a front running wheel, a rear running wheel, and a wheel drive mechanism to rotate them. This cable drive device rotates the cutting cable that is stretched around the object to be cut in an endless manner by rotating the cable drive pulley, and rotates the entire device to drive the front wheels and rear wheels. Therefore, the object to be cut is moved along a trajectory in a direction opposite to the object to be cut, during which time the object to be cut is cut by the cutting cable.

Although the cable drive device described above has a running front wheel and a running rear wheel that roll on a track, it does not have a means to ground and move it on a non-track surface, so it generally weighs 1 to 1.5 tons. When transporting a cable drive device, which can reach a length greater than that in some cases, at a construction site, for example, when installing it on a track or lowering it from a track, a lifting device such as a crane is required.

を容易に使用することができる。 When huge stones are cut out using wire sawing at a quarry, the quarry is generally large and there is always a crane, etc. to transport the cut stones, so a cable-driven method is used. These cranes and the like can be easily used to transport the equipment.

作業効率が低下する等の問題もある。 However, when cutting and partially demolishing reinforced concrete structures such as buildings, bridges, foundations, and subway station walls using wire sawing, the construction site is generally small and intricate, and sometimes cable drive equipment is installed indoors. Because of this, there are problems such as not being able to freely use cranes, etc. Furthermore, wire sawing of reinforced concrete structures differs from the simple cutting of huge stones in a quarry, and in many cases consists of a combination of multiple partial cuts with different cutting locations and cutting directions.
It is necessary to frequently transport the cable drive device, and if a crane or the like is raised and lowered each time, there are problems such as a decrease in work efficiency.

A cable drive device for a wire saw according to the present invention includes a cable drive pulley that circulates a cutting cable, a pulley mechanism that rotationally drives the cable drive pulley, and a pulley mechanism that rotationally drives the cable drive pulley.
In a device equipped with a front running wheel and a rear running wheel that roll along parallel tracks and a wheel drive mechanism that rotationally drives them, the grounding point is lower than that of the front running wheel and the rear running wheel. The front wheel for driving and the rear wheel for driving are provided so that they do not touch the ground when they are on the track, and at least one of them is provided with a front wheel for transportation and a rear wheel for transportation, and the wheel drive mechanism is configured to The present invention is characterized in that it further includes a torque limiter for limiting the rotational torque of the front wheels for driving and the rear wheels for driving.

When this cable drive device is placed on a non-track surface such as a road or floor, the front transport wheels and rear transport wheels are in contact with the non-track surface, and the front wheels and rear wheels are in contact with the non-track surface. Since it floats, the cable drive device can be easily transported on a non-track surface by pushing the cable drive device with an input or by rolling the front transportation wheel and the rear transportation wheel using a drive source. Since the front transport wheels and/or the rear transport wheels can then change direction, the cable drive can be freely steered to the destination during transport.

Therefore, by rotationally driving the front wheels for running and the rear wheels for running by the wheel drive mechanism, the cable drive device can be made to run on the track.
