Description

Heating device for preventing deformation of iron plate {HEATING APPARATUS FOR PREVENTING DEFORMATION OF STEEL PLATES}

The present invention relates to a heating apparatus for preventing deformation of an iron plate.

In order to increase the rigidity of the plate during ship construction, small assembly is formed by welding the plate and durable material.

Deformation occurs at the end of the plate due to the thermal stress generated at this time.

Deformation generated during the subassembly process has a characteristic that becomes larger and larger through the next stage of the intermediate assembly, control process. In order to correct this deformation, heating is performed on the back surface of the deformed member or steel plate in the heavy assembly and the contrasting process such as so-called bending work.

At this time, because the overhead work also has to be done, the work is difficult and the work fatigue increases.

In addition, since the heating operation generates heat in a general torch using oxygen and ethylene gas, there is a possibility of device explosion in case of gas leakage, so securing the torch safety is very important.

The heating device according to the prior art is inconvenient that the safety device is inadequate and configured to move along the rail, so that the operator must install the rail before working.

In addition, other common heating devices that do not use rails have inconveniences in that the worker must move the equipment when the equipment is running so that the equipment runs in a straight line at the time of work.

On the other hand, the automatic bending device for deformation correction of the iron plate according to the prior art, as shown in Figure 1, to implement the configuration of the traveling cart to be in close contact with the surface of the iron plate to correct the deformation of the iron plate installed vertically and horizontally In addition, the construction of the work-point heating and cooling work mechanisms is carried on the traveling trolley to perform the bending work by the automated device.

That is, the automatic bending device for deformation correction of the iron plate of the prior art is a driving motor 16 and a bevel gear, a belt, a pulley for rotating the wheel 11 and the wheel 11 for driving at each corner point of the main body, respectively, A traveling mechanism part 10 having a base 12 provided with a power transmission mechanism such as a shaft 15; An adhesion mechanism part 20 installed on the main body so as to generate an attraction force between the bottom surface of the main body and the working surface so that the main body moves in close contact with the working surface; A heating and cooling mechanism unit 50 mounted on the main body and provided with a torch and a cooling water injection nozzle supplied with external materials from both sides of the main body is installed to heat and cool a work point, and the meandering of the traveling mechanism unit 10 is performed. When generated, it includes a central moving mechanism having a motor 33, rack, pinion, etc. to move the position of the heating cooling mechanism unit 50 on both sides.

However, the automatic bending device for deformation correction of a prior art iron plate is manufactured for the process after small assembly to fit the iron plate deformation is generated after the small assembly through welding or the like.

For example, the automatic bending device for deformation correction of a prior art iron plate is configured to perform a heating operation in a heavy assembly or a contrasting process corresponding to a post-process, and in order to prevent deformation in advance by heating the steel plate in advance. As it can not generate a large thermal stress repeatedly, the meandering occurs during the running of the device, there is no separate guide means or automatic stop means, it is difficult to be used as a device for heating the iron plate in advance to prevent the occurrence of deformation before small assembly.

In addition, the automatic bending device for deformation correction of the iron plate according to the prior art, once the meander occurs, only by adjusting the meander by operating the center moving mechanism, it has a very difficult configuration of straight running.

In addition, the automatic bending device for deformation correction of the iron sheet according to the prior art has a disadvantage that the torch is distributed on both sides so that intensive heating work that can prevent in advance the deformation caused when forming the small assembly can not be performed at the same time running. .

In addition, the automatic bending device for deformation correction of the iron plate according to the prior art has a disadvantage that the automation of at least after the completion of work can not be made due to the absence of the means for recognizing the end of the member to be worked.

In addition, the automatic bending device for deformation correction of the iron plate according to the prior art has a relatively very low operation safety due to the failure of the safety device, the risk of explosion in severe cases because it is exposed to a safety accident such as backfire or gas leakage in the torch. I have it.

In addition, the automatic bending device for deformation correction of the iron plate according to the prior art is equipped with a complex power transmission device such as bevel gear, belt, pulley, etc. other than the motor, the device configuration is very complicated, in particular the wheel connected to the end of the power transmission device It is exposed outside, and has the disadvantage of not being protected by heat, heat or flame.

The gas supply is shut off and fire extinguishing occurs automatically.

In the same principle, the gas leakage detector 153 determines a gas leakage by using a known method of detecting a gas amount within a preset detection range, and operates the solenoid valve 152 according to the result. This is done in a timely manner.

As shown in FIG. 3 or FIG. 4, the operator guides the first guide arm 142 by clamping or unclamping the clamping lever 143 of the guide unit 140 to linearly travel the body 110. The second guide arm 144 is inclined so as to have a tilt angle t, so that the extending direction of the guide reference surface 1a of the member 1 and the longitudinal direction of the body portion 110 are not parallel to each other. Set to achieve
