Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a concrete floor direct finishing robot for directly finishing a concrete floor with a rotating iron.

[Prior Art] Conventional concrete floor finishing robots include, for example, the following.

That is, the concrete floor direct finishing robot includes a main body having running wheels, a bumper portion connected to the main body, and a trowel main body connected to the main body and having a rotating iron.

For traveling, a traveling wheel is driven by a servo motor by a wireless device to move forward or backward or rotate. Further, a gyro compass, a mileage sensor, a control device, and the like are incorporated in the main body, and automatic driving can be performed using these.

Three rotating irons are mounted on each of the left and right sides of the trowel body, and the trowel motor provided at the center of the trowel body rotates the rotating irons to directly finish the concrete floor. Further, the main body and the trowel main body are connected by a spring, so that even if the main body sways, the shake is not transmitted to the trowel main body and does not affect the finishing surface of the concrete floor.

In addition, artificial turf is attached to the outer circumference of the running wheels. Artificial grass is made of a material that does not easily adhere to concrete and has a coefficient of friction necessary for running.

[Problems to be Solved by the Invention] However, in such a conventional concrete floor direct finishing robot, the artificial turf is directly adhered to the outer periphery of the running wheel. ,
It is necessary to remove the running wheels from the main body and scrape off the artificial grass and the adhesive with a lathe, which causes a problem that replacement work takes time.

The present invention has been made in view of the above conventional problems, and the screwing operation of the drum to which the artificial turf is adhered to the running wheels does not require replacement work. The purpose is to provide a concrete floor direct finishing robot.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a trowel body having a main body having running wheels, a bumper portion connected to the main body, and a rotating iron connected to the main body. In the concrete floor direct finishing robot having the above, a drum is attached with screws and nuts as an exchange unit in which artificial grass is adhered to the outer wall of the running wheel.

[Operation] In the present invention, the artificial turf is adhered to the drum, the drum is used as a replacement unit, the drum is expanded and fitted into the running wheel, and the drum is fixed to the running wheel with the screw and the nut.

Therefore, the replacement work is less troublesome and the replacement work can be performed on site.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 6 are views showing an embodiment of the present invention.

First, the structure will be described. In FIGS. 5 and 6, 11 is a main body, and traveling wheels 12 and 13 driven by independent servo motors (not shown) are mounted on the left and right sides of the main body 11, respectively. The power cable 14 is connected to the upper part. A plurality of handles 15 for carrying the present invention 11 are attached to the left and right sides of the main body 11.
A gyro compass, a mileage sensor, a control device, and the like are incorporated inside the main body 11.

A bumper portion 16 is detachably connected to the main body 11, and the bumper portion 16 is connected to the main body 11 by one bumper 17, the other bumper 18, the bumper 18 and the bumper 17.
A leaf spring 19 provided between the bumper 18 and the bumper 17, and a wire 20 also provided between the bumper 18 and the bumper 17.

On the other hand, a trowel body 23 is detachably connected to the body 11 via a connecting portion 22 including a spring 21 and the like.
Even when the main body 11 shakes, the shake is not transmitted to the trowel main body 23 and the like, and the finished surface of the concrete floor is not affected. Three rotating irons 24 and 25 are mounted on the left and right sides of the trowel body 23, respectively, and these rotating irons 24 and 25 are rotated by the central trowel motor 26 to directly finish the concrete floor. I am trying to do.

A guard frame 27 for protecting the rotating irons 24, 25 is attached to the trowel body 23.

Here, as shown in FIG. 1, the artificial turf 31 is mounted on a drum 32, and the drum 32 is screwed to the running wheels 12, 13 with a screw 33 and a nut 34.

As shown in FIG. 2, the drum 32 is formed of a thin plate member in a cylindrical shape and can be expanded as indicated by an arrow.

Further, as shown in FIG. 3, a screw 33 projects inward from the drum 32, and the screw 33 is integrated with the drum 32.

As shown in FIG. 4, the running wheels 12 and 13 are formed with screw holes 35 into which the screws 33 are inserted.
It is designed to be fixed to 12,13.

Next, the operation will be described.

The traveling wheels 12 and 13 are driven by wireless devices via independent servo motors to perform forward and backward movement or rotation. In addition, automatic driving is performed using a gyro compass and a traveling distance sensor incorporated in the main body 11.

The rotating irons 24, 25 are driven by a trowell motor 26 to directly finish the concrete floor.

Here, the drum 32 to which the artificial turf 31 is adhered is used as a replacement unit, and when the drum 32 is attached to the traveling wheels 12 and 13, the drum 32 is expanded in the radial direction and fitted into the traveling wheels 12 and 13. That is, the screw 33 of the drum 32 is inserted into the screw hole 35 of the traveling wheels 12, 13. Then, the drum 32 is fixed to the traveling wheels 12 and 13 by tightening the nut 34.

When removing the drum 32 from the traveling wheels 12 and 13, the procedure reverse to the above may be performed. In this way, the drum 32 to which the artificial turf 31 is adhered can be easily replaced with respect to the running wheels 12 and 13 and at the site.

As a result, the manual replacement work is less troublesome.

[Advantages of the Invention] As described above, according to the present invention, the drum to which the artificial turf is adhered can be attached to the traveling wheel with screws and nuts as a replacement unit. . Also, replacement work can be performed on site.
