Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power supply device for an electric concrete floor finishing machine that levels a floor surface on which concrete has been poured.

[Conventional technology]

There are two types of concrete floor finishing machines that level the poured concrete floor before the concrete hardens: engine-driven machines that use an engine to rotate a rotary trowel, and electric machines that use an electric motor to rotate a rotary trowel. .

[Problem that the invention attempts to solve]

By the way, the engine-driven finishing machine is not restricted in leveling movement on the concrete pouring surface;
There is a lot of noise and vibration, whereas electric finishing machines have no noise and vibration, but a worker operates the finishing machine while handling the power supply cable with one hand, and another worker handles the power supply cable on the power supply side. However, even then, the cables may become tangled, the floor surface may be dragged along the surface and the concrete surface that has been carefully leveled may be damaged, and the cables that have been running on the floor surface may be cut by the rotating blades. was.

[Means for solving problems]

The present invention was devised to eliminate the shortcomings of the conventional electric concrete floor finishing machine, and its purpose is to efficiently finish concrete floors by one worker without being tied down to power supply cables. The purpose of the present invention is to provide a power supply device for an electric concrete floor finishing machine that can finish concrete floors. The other end of the swing arm is equipped with an automatic take-up reel, which is wrapped with a power supply cable that supplies power to the electric concrete floor finishing machine, and is pivoted so that the reel direction can be changed freely. This constitutes a power supply device for a surface finishing machine.

[Effect]

In the above configuration, the unwinding end of the power cable is connected to an electric concrete floor finishing machine, the switch is turned on, and a worker operates the finishing machine to level the concrete floor one by one. At this time, as the finishing machine moves, the take-up reel is pulled by the cable to which a constant tension is constantly applied, and the take-up reel changes direction toward the finishing machine, and the swing arm also pivots in that direction. In addition, the cable is automatically pulled out from the take-up reel in response to increases or decreases in the distance between the take-up reel and the finishing machine to maintain tension, so that workers do not have to operate the cable on the finishing machine side or the power supply side. The cables do not get tangled or hang down and drag on the floor surface, and the worker can efficiently finish the floor surface by himself without having to worry about cables.

〔Example〕

The present invention will be explained in detail below based on an illustrated embodiment.

The power supply device of the present invention has a support member 1 made of channel steel.
One end of a rotating arm 2 made of square steel is supported horizontally by a vertical pin 3, and an automatic take-up reel 5 on which a power supply cable 4 is wound is attached to the other end of the rotating arm 2. 6, the reel 5 is attached by a seat plate 7 such that the direction of the reel 5 can be changed freely.

When finishing the concrete floor, the power supply device described above is attached to the structure 8 at an appropriate location on the site. Attach the support member 1 with bending bolts 11, 11 (Fig. 1, Fig. 2),
If the structure 8 is a steel frame 9, attach it to the steel frame 9 with similar bending bolts 11, 11 (Figs. 3 and 4), pull out the power supply cable 4 of the take-up reel 5, and connect it to the electric concrete floor finishing machine 12. Connecting. Then, the worker turns on the switch and operates the finishing machine 12 to level the concrete floor surface 13 one by one. At this time, as shown in FIG. 4, as the finishing machine 12 moves, the take-up reel 5 is pulled by the cable 4 to which a constant tension is constantly applied by the take-up reel 5.
changes its direction toward the finishing machine 12, and the swing arm 2 also pivots in that direction, and the cable 4 also automatically moves away from the take-up reel 5 in response to an increase or decrease in the distance between the take-up reel 5 and the finishing machine 12. The tension is maintained when the drawer is pulled in, and even if the worker does not operate the cable 4 on the finishing machine 12 side or the power supply side, the cable 4 will not become tangled or hang down and drag on the floor, and the worker will not be bothered by the cable 4. One person can efficiently finish the floor surface.

[Effect of idea]

As explained above, according to the present invention, one end of the swivel arm is pivotally supported horizontally on a support member that can be attached and removed from a structure on site, and the other end of the swivel arm is provided with an electric concrete floor surface finish. The power supply device for the electric concrete floor finishing machine consists of an automatic take-up reel wrapped around the power supply cable that supplies power to the machine, which is pivoted so that the direction of the reel can be changed. On the other hand, the disadvantages of electric concrete floor finishing machines, which were disadvantageous in terms of cable handling, are eliminated, and the floor finishing can be efficiently completed by one worker without cable troubles. .
