Therefore, a technique is known in which the returned scaffolding iron plates are washed one by one and placed on a press stand by a forklift, and the deformation is corrected by the press machine.

[0003]

However, the above-mentioned technique is a very laborious and dangerous work because the above-mentioned technique is corrected one by one and the opposite surface is turned over to correct the iron plate. .

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a scaffolding iron plate deformation correcting device which allows one worker to easily and continuously clean and correct the scaffolding iron plate in a short time.

[0005]

According to the present invention, in a deformation correcting device for correcting the deformation of a scaffolding iron plate composed of a thick iron plate, a traveling rail on which the hoist travels is provided, and the hoist can travel freely on the traveling rail. The hoist has a gripping device that vertically holds the iron plate at the end of the hanging wire, and the scaffold is vertically suspended below the rail. An iron plate correction device for correcting the deformation of the iron plate is provided.

Further, according to the present invention, the iron plate correcting device comprises a pair of cylinder bases standing upright on a base and a plurality of hydraulic cylinders mounted on the cylinder bases so that the plungers face each other. And a correction form movably provided on the facing surfaces of the pair of cylinder bases, respectively, and a control box for operating the hydraulic cylinder.

Further, according to the present invention, the iron plate cleaning device comprises a plurality of pairs of rotating brushes vertically rotatably provided on a base, nozzles, a water pump, a motor for rotating the brushes, and a casing. There is.

According to the present invention, the traveling rail is endless.

According to the present invention, the traveling rail is provided with a plurality of hoists.

Further, according to the present invention, a head is detachably attached to the tip of the plunger of the hydraulic cylinder.

[0011]

The present invention is configured as described above, and the returned scaffolding iron plate is carried under the rail of the deformation correcting device, the wire of the hoist is lowered, and the end of the iron plate is held by the gripping device. Grasp it, wind up the wire of the hoist, hang the iron plate vertically and move it along the rail, and drive the cleaning device to spray water from the nozzle while passing it between the brushes that rotate vertically. Wash both sides simultaneously. If it cannot be washed in one time, it can be washed back and forth.

Then, the iron plate vertically suspended between the cylinder bases of the iron plate correction device is moved, the correction form is moved to the deformed portion, and the hydraulic cylinder on the opposite side is driven by operating the control box to press. And fix it. By the same operation, repair work from both sides of the iron plate, move to the carry-out place along the rail when the correction is completed, lower the iron plate by operating the hoist, and release the gripping device to wash the iron plate, repair it and re-install it. It is ready for lease.

If a plurality of hoists are installed on the rails, it is possible to work continuously, so that the working efficiency is improved and the head of the plunger of the cylinder can be replaced according to the shape of the portion to be corrected. Work becomes easy.

FIG. 1 is a plan view showing the structure of a deformation correcting device for a scaffolding iron plate according to the present invention. A rail 1 formed in an elliptical shape.
An iron plate cleaning device 2 and an iron plate correction device 3 are provided below one of the straight portions 1a, and the other straight portion 1b serves as a loading / unloading place for the iron plates.

FIG. 2 is a perspective view of an iron plate correcting device generally designated by reference numeral 3, in which a rail 1 is provided with a hoist 4 so that the hoist 4 can travel freely. Individual) gripping devices 6, 6 are provided, and the iron plates 7 are gripped by the gripping devices 6, 6 and vertically hung.

An iron plate correcting device 3 is located below the iron plate correcting device 3, and the iron plate correcting device 3 is provided with cylinder bases 9 and 9 on a base 8 so as to face both sides of the iron plate. A plurality (five in the illustrated example) of hydraulic cylinders 10 are horizontally mounted so as to face each other.

A correction form 11 is movably provided along the slide rail 12 on the surface 9a facing the cylinder base, and the hydraulic cylinder 10 is not shown in the figure by operating a button 15a provided on the control box 15. It is driven by pressure oil supplied from a hydraulic unit. Here, the code | symbol 4a has shown the operating panel of a hoist.

Reference numeral 14 indicates a pin hole for fixing the mold 11.

The operation of the iron plate correcting device 3 will be described below with reference to FIG. 3 which is a view taken in the direction of arrow A in FIG.

When there is a convex portion on the B side of the iron plate, as shown in the figure, the left mold 11 is moved on the slide rail by the slide bearing provided on the mold, and the right hydraulic cylinder 1
The iron plate is pressed and corrected by the head 13 of the plunger 10a of 0. When the modification of the B surface is completed, the C surface is modified using the mold 11 on the right side and the hydraulic cylinder 10 on the left side in the same manner. In this case, depending on the state of deformation of the iron plate, the head 13 can be replaced with a shape corresponding to the deformation, and the work is facilitated.

FIG. 4 shows a perspective view of the iron plate cleaning apparatus 2. A pair of casings 22, 22 are provided on the upper portion of the base 21, and the casing 22 has a shaft 24 on which a rotating brush 23 is vertically provided. Rotating around, the brushes are arranged to rotate face to face.

The brush 2 is attached to the upper part of the casing 22.
A motor 25 for driving 3 and a pump 26 for supplying water to a nozzle 29 (see FIG. 5) are provided, and a guide pipe 24 is provided in a passage 27 of a vertically suspended iron plate.

FIG. 5 shows a state in which the upper portion of the casing of FIG. 4 is removed, and a plurality of (six in the illustrated example) rotating brushes 2 are provided.
3 is driven by a motor 25 via chains 30 and 31, and a nozzle 29 is connected to a pump 26 by a water circuit (not shown). A rubber cover 28 is provided on both sides of the passage 27 of the iron plate 7.

Therefore, the brush 23 is driven by the motor 25.
When the iron plate is passed through the passage 27 while water is supplied to the nozzle 29 by rotating the pump 26, both sides of the iron plate can be cleaned at the same time.

Further, if the iron plate that has been cleaned and corrected is unloaded at the carrying-out place, for example, on the fork of a forklift,
It can be easily carried out, and if multiple hoists are provided on the rail, cleaning and repair work can be performed continuously.

[0027]

Since the present invention is constructed as described above, the following excellent effects can be obtained. (1) Since the iron plate is cleaned before the deformation of the iron plate is corrected, the correction work can be performed easily with high accuracy. (2) Both sides can be cleaned and repaired while the iron plate is suspended in a basket.
It is efficient and safe, and continuous work is possible. (3) Therefore, the cost until re-lease is low.
