Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface treatment device for panels such as steel scaffolding boards, and more particularly, to an apparatus for removing hardened concrete that resists adhesion to the surface of scaffolding boards and the like.

Generally, when working at heights at a construction site, steel scaffolding boards are suspended on a temporary framework made of pipe materials, etc., and workers stand on these steel scaffolding boards and carry out various tasks such as pouring concrete and treating walls. It is being done.

In such cases, concrete often falls onto the steel scaffolding boards and hardens to resist adhesion.

Therefore, in consideration of work safety, steel scaffolding boards are reused after removing the hardened concrete. However, methods are used to forcibly peel off the concrete using the impact.

However, this method poses problems such as the risk of damaging the steel scaffolding boards, the risk of peeling off the anti-rust plating, and the inefficiency of manual work. have.

Therefore, a device for mechanically removing concrete adhering to steel scaffolding boards was developed in U.S. Pat. No. 54-38124.
It is stated in the No.

This structure constructs a rotating impact body by loosely fitting impact rings onto multiple shafts provided in the radial direction of a rotating shaft so that they can move freely in the radial direction, and each impact ring is rotated while rotating this rotating impact body. It is designed to hit the concrete of the scaffolding board one after another and peel off the concrete one after another.

However, according to this structure, the concrete of the scaffolding board is
Since each impact wheel peels off one after another, it takes a lot of time and is inefficient to peel off, and there is a large risk that the rust-proof plating will also peel off. It has the disadvantage that the tendency is more pronounced at the top and corners of the anti-slip protrusions that are formed.

The present invention was developed in view of these points, and involves supporting a panel such as a scaffolding board using forward and reverse rollers, moving it forward and backward, and depositing concrete on the surface of the panel as it moves forward and backward. By configuring the structure to crush and remove concrete using a group of rotating blades that repeatedly vibrate in the vertical direction, concrete that adheres to the surface of panels such as scaffolding boards can be efficiently removed without damaging the panels. The present invention provides a surface treatment device.

The motor frame 22 is supported by the front and rear cylinders 25 and is slid up and down along each guide rod 24.

Further, a vibration motor 27 as a vibration source is fixed on the bottom plate 22a of the motor frame 22.

Further, a vibration frame 28 is integrally fixed to the lower surface of the bottom plate 22a of the motor frame 22 with a plurality of bolts 29 and nuts 30.

This vibration frame 28 has support frames 32 arranged vertically and horizontally at predetermined intervals on the lower surface of a substrate 31, integrally protruding in a lattice shape, and an edge frame 33 integrally protruding from the periphery. Further, a plurality of mounting holes 34 through which the bolts 29 are inserted are bored at predetermined positions in the substrate 31.

Furthermore, communication holes 35 and 36 are formed in communication with each other at a predetermined interval in the horizontal frame and the edge frame 33 in the width direction of the support frame 32 formed on the substrate 31 of the vibration frame 28, and the communication holes 35, A horizontal shaft 37 is inserted through each of the horizontal shafts 36, and a nut 44 is fastened to a threaded portion 38 formed at both ends of each horizontal shaft 37.

In addition, a large number of rotary blade bodies 40 having spacers 39 at both ends of each support frame 32 are movably mounted in parallel in sequence with respect to each of the horizontal shafts 37, and the large number of rotary blade bodies 40 vibrate. A rotary blade group 41 is configured at the bottom of the frame 28.

As shown in FIG. 7, this rotary blade body 40 has an insertion hole 42 bored in the center with a diameter larger than the diameter of the horizontal shaft 37 that is loosely fitted into the horizontal shaft 37, and a through hole 42 in the peripheral side. A large number of cutting blade pieces 43 are integrally formed in a substantially gear shape.

In the device configured in this way, the guide port 3 of the machine frame 1
Insert a panel, for example, scaffolding board A, into the
is supported on a forward/reverse rotation roller 6.

This scaffolding board A is formed of a steel plate or the like in a horizontally long rectangular shape, and the upper surface board part B has protrusions C that bulge out in a grid pattern in the vertical and horizontal directions, and also, Hooks D are protruding from the front and back to lock onto pipes of the temporary framework.

Next, the geared motor 10 with a brake is driven once,
The forward and reverse rotation rollers 6 are rotated in conjunction with each other via the speed reducer 11 and the endless chain 13, and the vibration motor 27 is driven.

As a result, the scaffolding board A on each forward/reverse roller 6 is moved back and forth in the left-right direction in FIG. 1 at predetermined intervals.

Further, a vibration frame 28 integrated with the motor frame 22 to which the vibration motor 27 is fixed is vibrated up and down along the guide rod 24 by the vibration motor 27 .

Each of the rotary blade groups 41 of the vibrating frame 28 is rotated in conjunction with the movement of the scaffolding board A while vibrating in the vertical direction with respect to the scaffolding board A that is moved forward and backward in the left-right direction. The concrete adhering to the upper surface plate part B of the scaffolding plate A is crushed and removed by a large number of cutting blade pieces 43.

In this case, since each of the rotary blade bodies 40 of the rotary blade group 41 is mounted on the respective horizontal shafts 37 so as to be freely movable in the radial direction, the rotary blades When each cutting blade piece 43 of the body 40 is located on the protrusion C of the scaffold board A, and when each cutting blade piece 43 of the rotary blade body 40 is located within the recess E of the scaffold board A, the The interlocking rotation tongue 4 moves up and down within the size range of the insertion hole 42, so that the concrete adhering to the ridges C and the recesses E of the scaffold board A can be reliably crushed and removed.

According to the present invention, a panel such as a scaffolding board is arranged on the forward and reverse rollers, and the panel is moved by the rotation of the forward and reverse rollers, and a group of rotary blades is provided above the forward and reverse rollers with respect to the panel. By repeatedly vibrating in the vertical direction, the concrete adhering to the panel can be reliably crushed and removed. Therefore, each rotary blade moves up and down individually and simultaneously and collides with the concrete at each part of the panel's surface form, and its repeated vibrations can greatly crush the concrete at once, thus making it possible to break the panel. There is no risk of damage to the panel, unlike the conventional method in which concrete is removed from the panel by striking it with a stick, etc., and there is no risk of damage to the panel. It is extremely inefficient compared to the method of hitting the concrete with rings one after another and peeling off the concrete one after another, and it also requires polishing the tops and corners of the protrusions on the panels to remove the rust-preventing plating. In addition, the surface treatment work for removing concrete that adheres to the panel is automated using the panel that moves forward and backward and a group of rotating blades that vibrate in the vertical direction relative to the panel, greatly improving work efficiency. Furthermore, since the structure is simple, it is easy to manufacture.
