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, the traveling wheels are driven by a servomotor by a wireless device, and the front and rear wheels are rotated. In addition, a gyro compass, a mileage sensor, a control device, and the like are incorporated in the main body, and automatic driving using these is enabled.

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.

[Problems to be solved by the invention] However, in such a conventional concrete floor direct finishing robot, concrete is gradually hardened after being placed, and finishing work is performed several times during this period. However, if the robot is heavy, it cannot be finished because it sinks early, and if it is light, on the other hand, the force that pushes the rotating iron against the concrete is insufficient and the finish cannot be done at a later time. was there.

The present invention has been made in view of such conventional problems, and by allowing the weight to be detachably mounted on the trowel body, it is possible to cover a wide range from when the concrete is soft to when it becomes hard. It is an object of the present invention to provide a concrete floor finishing robot capable of performing appropriate finishing.

[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 a concrete floor direct finishing robot having the above, a guide shaft for detachably mounting a weight on the trowel body is provided.

[Operation] In the present invention, when the concrete hardens to some extent, the weight is gradually inserted into the guide shaft of the trowel body.

Therefore, it is possible to finish over a wide range from when the concrete is soft to when it becomes hard. Also,
By adjusting the number of weights, it is possible to adjust the pressing force of the rotating iron, and it is possible to perform an appropriate finish that matches the hardness of concrete. Since the robot body is light, it can be easily transported by removing the weight.

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

1 to 5 are views showing an embodiment of the present invention.

First, the configuration will be described. In FIGS. 4 and 5, reference numeral 11 denotes a main body, and the main body 11 has traveling wheels 12 and 1 driven by independent servo motors (not shown).
3 are mounted on the left and right sides, and a power cable 14 is connected to the upper part. Also, on the left and right sides of the main body 11,
A plurality of handles 15 for carrying the main body 11 are attached. A gyro compass, a traveling distance sensor, a control device, and the like are incorporated in 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, and the bumper 18
And a wire spring 20 provided between the bumper 18 and the bumper 17 as well.

On the other hand, the trowel main body 23 is detachably connected to the main body 11 via a connecting portion 22 including a spring 21 and the like, and even if the main body 11 sways, the sway is not transmitted to the trowell main body 23 and the like, and the concrete floor finishes. It does not affect the surface. Three rotating irons 24, 25 are mounted on the left and right sides of the trowel body 23, respectively, and these rotating irons 24, 25 are rotated by a trowel motor 26 provided at the center to directly install the rotating irons on the concrete floor. I try to finish it.

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

Here, as shown in FIG. 1, a guide shaft 31 is provided on each of the left and right sides of the trowel body 23, and a weight 32 is detachably attached to the guide shaft 31.

As shown in FIG. 2, the weight 32 is formed with two small holes 33 into which the guide shaft 31 is inserted and a large hole 34 into which the motor shaft of the trowell body 23 is inserted, and a step portion 35. Are formed.

That is, as shown in FIG. 3, by forming the step portion 35, it is easy to remove even if several pieces are stacked.
Also, when you stack them, you do not have to worry about pinching your hands.

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 inside the main body 11.

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

Here, if the weight 32 is placed at an early stage after the concrete is placed, it will sink and the finishing work cannot be performed.
Do the finishing work without placing 2. Weight on robot 32
The weight of the robot before mounting is designed to be as light as possible.

After that, when the concrete hardens to some extent, the weight 32 is gradually placed on the trowel body 23. In this case, since the weight 32 is positioned by the guide shaft 31, it does not fall. Further, the weight 32 has a step portion 35.
Therefore, there is no need to worry about pinching the hand 36 when stacking, and it is easy to remove even when stacking several hands.

In this way, the number of the weights 32 placed on the rotary iron 24,
The force of pressing 25 onto the concrete is increased, and the finishing can be efficiently performed even if the concrete is considerably hardened. That is, it is possible to finish over a wide range from when the concrete is soft to when it becomes hard. Also, by adjusting the number of weights 32, the rotary iron 24,
The pressing force of 25 can be adjusted, and an appropriate finishing can be performed according to the hardness of concrete. Furthermore, since the weight of the pot body is light when the weight 32 is removed, it is easy to carry.

Next, FIG. 6 is a diagram showing another embodiment of the present invention.

In order to increase the pressing force of the rotating irons 24 and 25, it is sufficient to place the weight 32 on the trowel body 23 as shown in FIG. The weight of the trowel body 23 becomes too heavy, and the running wheels 12 and 13 of the body 11 idle.

Therefore, in such a case, it is necessary to place a weight on the main body 11 to increase the driving force of the traveling wheels 12, 13.

In FIG. 6, two units are provided on the left and right sides of the main body 11 for a total of 4 units.
Individual handles 15 are provided, and these handles 15 are
It is for transporting the main body 11, and it is located substantially symmetrically with respect to the running wheels 12 and 13 in the front-back direction. Can be maintained.

The weight 37 is formed in a substantially U shape and has a groove 38 to be inserted into the handle 15.

Thus, even if the weight of the trowel body 11 is increased, the running wheels 12 and 13 of the body 11 do not idle,
Finishing can be done.

[Effects of the Invention] As described above, according to the present invention, since the weight can be detachably mounted on the trowel body, it is possible to finish over a wide range from when the concrete is soft to when it becomes hard. Can be done. Also, by adjusting the number of weights, the pressing force of the rotating iron can be adjusted, and an appropriate finish suitable for the hardness of concrete can be performed.
