Description

Concrete pouring level adjuster {LEVELING ADJUSTER FOR CONCRETE POURING}

The present invention relates to a concrete pouring leveler, and more particularly, to a concrete pouring leveler configured to automatically perform leveling work on a concrete pouring surface through remote control.

In the case of civil engineering or construction of a building or road construction, the floor can be formed by pouring concrete using a formwork and then curing the concrete.

Here, during the concrete pouring work, a flattening work must be performed to obtain an even filling of the concrete and a flat surface.

In the conventional concrete flattening work, a worker first performed a full surface leveling operation using a scraper, and then performed a partial surface leveling operation using a trowel secondly to complete the concrete leveling operation.

However, many workers must be mobilized for the conventional concrete leveling work, and there is a problem that the work time is also long. In addition, there is a problem that the work result of concrete flattening also varies depending on the operator.

Accordingly, various researches and developments have been conducted on a concrete placing level adjuster capable of more accurately, simply, and automatically performing a concrete leveling operation.

And the moving wing 440 is coupled to the rotating plate 430 . The moving wings 440 are spaced apart from each other at predetermined intervals along the circumference of the rotating plate 430 .

The movement wing 440 may be formed such that its width becomes narrower as it moves away from the rotating plate 430 . This is to effectively move the movable assembly 400 in a state in which it does not get caught in reinforcing bars and other construction materials installed on the floor during the moving process. In addition, since most of the driving force transmitted to the moving wing 440 is transmitted to the wide part of the moving wing 440 located close to the rotating plate 430, the movement of the moving assembly 400 can be done effectively.

On the other hand, the supply amount control unit 300 is provided at the front of the leveling assembly 200, and is configured to control the amount of concrete guided to the leveling assembly 200.

Here, the spiral pitch of the first transfer screw 310 is formed larger than the spiral pitch of the second transfer screw 340, so that the first transfer screw 310 primarily transfers a large amount of surplus concrete to the first transfer screw ( 310), the second conveying screw 340 is configured to discharge the other surplus concrete to one side of the second conveying screw 340 in the state of being discharged to one side of the second conveying screw 340.

The second transfer screw 340 is rotated by the second rotation unit 350, and surplus concrete may be transferred along the spiral direction of the second transfer screw 340. Here, the second rotating unit 350 may transmit rotational force to the second conveying screw 340 through a belt.

And the second supply amount control plate 360 is provided at the rear of the second transfer screw 340 .

The second supply amount control plate 360 controls the amount of concrete guided to the flattening assembly 200 and simultaneously guides the transfer direction of the surplus concrete transferred outward through the second transfer screw 340.

It is done. That is, the rotational frame 370 may be rotated based on the link shaft 371 by the expansion and contraction of the rod provided in the first cylinder 380 .

For example, when the height of the poured concrete at the current working position is higher than the reference level while the concrete pouring leveler 1000 is performing the leveling operation of the poured concrete, the rotation frame ( 370) may be moved to the lower side of the base frame 100 to increase the discharge amount of surplus concrete.

A light receiving unit (not shown) may be provided in the supply amount adjusting unit 300, and the light receiving unit may be provided from a laser level (not shown) that provides required concrete flat surface height information in a state disposed outside the work space. By receiving the irradiated light, the supply amount controller 300 can selectively control the discharge amount of excess concrete.

In this way, the concrete pouring level adjuster 1000 can selectively rotate the rotational frame 370 according to the height of the poured concrete at the working position and selectively adjust the discharge amount of surplus concrete.

Meanwhile, the leveling unit 500 maintains the level of the base frame 100 while the concrete placing level adjuster 1000 moves.

And one end of the third cylinder 540 is coupled to the rotating shaft 520, and the other end of the third cylinder 540 is supported on the upper portion of the support frame 410. The support frame 410 may be rotated based on the hinge axis 413 by the expansion and contraction of the rod provided in the third cylinder 540 .

In this way, the leveling unit 500 includes the second cylinder 510 and the third cylinder ( so that the base frame 100 maintains a horizontal state while the concrete pouring level adjuster 1000 proceeds with the flattening operation of the poured concrete). The moving assembly 400 can be selectively moved up, down, left, and right through the extension and contraction of the rod provided at 540 .

Here, a horizontal sensor (not shown) for measuring the horizontal state of the concrete placing level adjuster 1000 may be further provided in the concrete pouring level adjuster 1000, and the concrete pouring level adjuster 1000 receives information provided from the level sensor. Leveling of the concrete placing level adjuster 1000 may be performed based on the foundation.
