Description

[Detailed Description of the Invention] The present invention mainly relates to a moped crane used for removing deposits from concrete wooden forms and the like.

Concrete is currently used in a wide variety of fields, including footings, foundations, columns, beams,
In addition to being used in all important building elements such as girders, wall slabs, and roofs, it is also widely used in road pavements, airport runways, bridges or dams, irrigation channels, water diversion structures, and more. Many are used in the form of masonry parts such as building blocks and bricks.

When pouring concrete, a wooden formwork is used, and the concrete is placed inside the formwork by hand-pounding, kneading, or mixing around the reinforcing bars, or by digging on or near the vertical surface. It is poured and solidified.

However, after the concrete hardens, the formwork is removed, various finishes are applied to the concrete surface, and the formwork is subjected to removal of adhering concrete, dust, etc. in preparation for reuse. .

Incidentally, in the past, the work of removing such deposits from the formwork was generally carried out by manually scrubbing the formwork one by one using an iron tool called a scraper. However, since this type of work is done manually, it cannot be disputed that it is inefficient, and concrete casting, which requires many formworks, takes a lot of time and is extremely troublesome work. .

The present invention has been devised to deal with such a situation and to efficiently carry out the work of removing deposits using a motor.

That is, the object of the present invention is to provide a trolley that is easy to move because it has wheels for transportation, and can also perform light deposit removal work using a brush roll driven by a motor. A brush roll is rotatably supported by a mounting frame at the tip of the rod, and a motor is disposed near it via a mounting plate, so that the brush roll can be driven by a chain transmission from the motor or the like. It is characterized by having a pair of wheels and a jump prevention member provided below the tip of the holding rod.

Hereinafter, embodiments of the present invention will be described further based on the accompanying drawings.

Figure 1 is a side view of the brace of the present invention, Figure 2 is a partially cutaway top view of the brace in the A-A direction, and Figure 3 is the same B.
- It is a rear view as seen from the direction of arrow B.

In each of these figures, reference numeral 1 denotes a holding rod, at the lower end of which a brush roll 3 is pivotally supported on both sides via a mounting frame 2, and at a slightly upper position, a brush roll 3 is also supported via a mounting plate 4. A motor 5 is provided. A chain 6 is placed between the brush roll 3 and the motor 5, extending over sprocket foils etc. attached to the side of the brush roll 3 and the side of the motor 5, respectively, to drive the brush roll 3 as appropriate. I'm starting to get it.

Note that 7 is a wiring connected to a power source for operating the motor 5.

On the other hand, a pair of moving wheels 9 are provided below the motor 5 installation position of the holding rod 1 via a wheel mounting frame 8, and a pair of moving wheels 9 are provided near the tips of the wheels 9 to prevent the motor 5 from jumping up. When the jump prevention member 10 is attached to the holding rod 1 and the tow is in use,
or to prevent it from tipping over and prevent contamination during periods of rest.

In the above configuration, it is preferable that the brush roll 3 can be replaced as appropriate, and any material for the roll can be used as long as it can remove deposits attached to the formwork. In particular, although the formwork is mainly made of wood, considering that it can also be used for forms made of other materials, it is effective for the work to use brush rolls that are suitable for each type of material. In the figure,
11 indicates a formwork.

The crane of the present invention is constructed as described above.Next, the work of using this crane to remove deposits from the formwork will be explained.The crane of the present invention is placed on the formwork 11 that has been removed from the concrete. When the motor 5 is operated, the brush roll 3 interlocked with the motor 5 rotates, and the jump prevention member 10 prevents jump contamination and sequentially removes foreign matter adhering to the mold surface.

At this time, by moving the holding rod 1 forward with the wheels while pushing it, it is possible to sequentially remove deposits over a wide area on the formwork.

In addition, the rotation of the brush roll 3 by the operation of the motor 5 removes deposits and at the same time provides forward torque, and by simply lightly grasping the holding rod 1, the crane of the present invention can be moved forward very easily.

Furthermore, even if the crane of this invention is left as it is when work is stopped, it will not fall over because it has a fall prevention member with a pair of wheels.

In this way, the work of removing deposits from the formwork by scraping can be carried out efficiently, and the conventional work time can be greatly shortened.

Furthermore, if the brush roll 3 is replaced whenever it becomes worn out, deposits can be removed as effectively as before.

As described above, the present invention has a motor-driven brush roll attached to the tip of the holding rod, which improves the efficiency of removing deposits from concrete formwork, which previously had to be done manually. The rotational drive of the brush roll not only removes deposits from the formwork surface, but also increases the torque in the forward direction of the crane. This assists in making the twitch movement extremely light and reduces the force required to push the pusher rod forward, which has an excellent effect of eliminating the feeling of fatigue caused by long-term use.

In addition, the crane of the present invention is equipped with a pair of wheels and an anti-jumping member, which prevents it from tipping over and maintains a stable condition not only during use, but also when left unattended, and is extremely easy to handle.
In addition, jumping contamination is also prevented, and its practical value is expected to be great in conjunction with the use of concrete, for which demand is increasing.
