Abstract

PROBLEM TO BE SOLVED: To solve such problems with a road cutting equipment that the operation of a walk operating road cutting equipment is extremely dangerous in a repair work on a congested road, since the repair work may be performed not only on a flat surface but also on a three-dimensional side surface and a high lift surface depending on the type of the repair work, a cost is increased when machines suitable for these works are prepared, and since the supply of cooling water for a diamond blade is performed intermittently, an extra work time is needed. SOLUTION: This passenger type cutting equipment can increase the safety of an operator because of being riding type. A twin cutter device is mounted together with a 360 deg. rotating mechanism, lifting mechanism, and lateral movement mechanism for a forklift arm on the equipment so that the works on the flat surface, three-dimensional side surface, and high lift surface can be performed by one unit of road cutter in one process. Also, the work time can be shortened by towing a cooling water cart.

2. Description of the Related Art The prior art is a single operation of cutting a flat road surface with a road cutter, and core removal is only on two surfaces, a flat surface and a side surface, and each working machine has a separate function. Since it is a machine, it was necessary to prepare various working machines depending on the content of the work.

DISCLOSURE OF THE INVENTION The present invention is an engine type riding type machine, which is a device capable of changing the cutting angle in the 360 ° direction, and is a cutter machine capable of cutting a road surface or a wall surface at an arbitrary angle. It can also be used as a concrete core removing device. In the device of the present invention, the two left and right cutter devices can move up and down in the direction of 360 ° in the vertical direction up to 3 m and can cut at any height.
The inclination can be fixed between ° and 45 °, so V-cut,
Parallel (slash) cutting can be completed simultaneously in one step. Next, from a safety point of view, conventionally, road cutting work is a work involving so-called 3K, where a danger of collision with another vehicle is always expected because it is a walking driving system. Since the present invention uses a forklift as a passenger, it is possible to solve all of the above 3K at once. Further, the drive of the cutter device uses the hydraulic pressure of the forklift truck.

[0004]

Each function of a traveling device, a lifting / lowering work device, and a fork moving device of a fork lift truck is utilized. In addition to the rotation mechanism of 360 °, the cutter device itself is equipped with a tilt angle cutting device of 0 to 45 ° left and right, so that V cutting and parallel (// slash) cutting can be performed at one time, and any cutting is possible. Angle cutting is also possible. These devices are means for solving the problems.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments will be described with reference to the drawings. As shown in the side view of the forklift and the loading cutter of FIG. 1, the oblique cutting cutter device and the core removing device are attached to the 360 ° rotating device of the lift and the fork moving device, so that the three-dimensional cutting work and core of the present invention are performed. Enables removal work. The trailing device represents a towed water tank truck.

Claims (6)

[Claims] 1. A cutting having a mechanism capable of changing an objective cutting angle by using a hydraulic motor as a power source on both sides of a tip end of a mechanism for lifting an arm of a forklift, a mechanism for rotating a 360 ° and a mechanism for moving left and right forks individually in parallel. Mounting the device,
A device that cuts from the ground plane up to 360 ° with a diamond blade. 2. A core cutter is attached to a rotary shaft of a diamond blade by simultaneously operating the parallel movement device of claim 1 and the cutting device of the present invention, and the core is removed at an arbitrary angle with respect to a surface to be cut. It is possible to work. 3. A height of 3 m using the lifting device according to claim 1.
Parallel cutting of side wall up to, diagonal cutting, core cutting possible. 4. The cutting device of the present invention comprises a forklift 3
Separately from the 60 ° rotation mechanism, up to 4 left and right independently
The mechanism is tiltable up to 5 ° and can be driven, so two diagonal cuts or four parallel cuts can be made at the same time. 5. A water tank truck traction device is provided to replenish cooling water to the diamond blade or the core cutter portion during cutting work. Conventionally, since a hose is supplied from a trailing truck, only a portion corresponding to the extension of the hose is provided. It took time and effort to move the cutter wheel forward and then follow the truck again. 6. It is obligatory to clean the cutting dust, sludge, etc. discharged at the time of cutting after the cutting work. Currently, after the work is completed, it is manually cleaned with water sprinklers and rubber sardines.This device replaces the core cutter with a cylindrical brush.
Since the worker can clean the forklift with a passenger, it saves time and effort and eliminates danger.
