The invention relates to a device for protection of the enclosure integral part of the welding machine during a change of its location.

Proposed pending the invention relates in particular to a device to protect the body parts of the welding machine when the welder changes their location. For example, when carrying out welding work there are often situations in which the user moves an integral part of the welding apparatus, for example, a coil with a filler rod or wire feeder, welding, and transportation must be carried out by tightening a respective component parts. When pulling or pushing the component parts of the welding machine on the floor they are damaged.

Therefore, the objective of the invention is to create a device with which it is possible to provide optimal protection for the housing or located in it component parts, if the welder, for example, pulls or moves them across the floor.

The objective of the invention is solved by means of the protection device when moving to secure or protect the body in the form of a plate which is on the outside or facing away from the protected enclosure side provided with elevations to reduce the contact surface and resistance to friction. Pre is respectful is something that case on the ground or on the floor may be removed or tucked up, for example, suitable for carrying out the process of welding position, without damage to the shell. Thus, the lacquer on the body is not damaged, and the body stays and then, in particular, are protected from corrosion. Also due to the use of safety devices when moving creates a stable fit, if the body leans to the side. For example, the wire feeder to change it is located the coil with filler wire may be folded on the protection device when moving.

In a preferred embodiment, the elevation consistent with the direction of the expected change in the location. Such elevation are easily implemented controls to reduce the contact surface and resistance to friction.

If the conical eminences have done cross-section, in the preferred embodiment, it is possible to reduce the resistance to friction. When using such elevations advantage is that the location of the body cannot be easily changed undesirable as it could be, for example, when using rollers.

The fixing device protection when moving is performed in the preferred embodiment, on the inner side or on the side, about ashenai to the protected enclosure. By a corresponding performance can be adjusted by tilting the device protection during the move. Due to the detachable connection device protection when moving it can be easily replaced.

In the preferred embodiment, by means of measures for detachable fastening of the elevations on the protection device when moving ensure that the contact rails can be replaced separately. As a result of the contact of the runners may be used and other material, which, for example, further reducing the resistance to friction and wears out slower.

The form of the protection device when the move is aligned with the shape of the protected enclosure, for example to form the side wall of the shielded enclosure.

In the introduction it should be noted that the same parts of the embodiment of the invention are supplied with the same reference position.

Figure 1 shows the welding apparatus 1 or welding operator to carry out various processes or methods, for example, welding consumable electrode inert gas welding consumable electrode in an atmosphere of active gas, or TIG welding (tungsten inert gas / TIG welding (tungsten) is electrodom in the atmosphere of active gas, or welding electrode, dvuhtokovoe welding or welding successive arcs, welding arc plasma or soldering, etc.

Welding machine 1 includes a source 2 current located in it the element 3 of the power device 4 controls and other, are not depicted components and wires, for example a switching element, control valves, etc. the control Device 4 is connected, for example, with a control valve located in the supply bus for gas supply 5, in particular a protective gas, for example CO2, helium or argon and the like, between a gas cylinder 6 and the welding torch 7 or burner.

Moreover, by means of the control device 4 may be regulated by another mechanism 8 wire, which is typically used in the process of welding consumable electrode inert gas welding consumable electrode in an atmosphere of active gas, and the supply bus, a filler material or welding wire 9 is served from storage drum 10 or Bay with wire in the area of the welding torch 7. Of course, it is possible that the mechanism 8 wire, as is known from the prior art, integrated in the welding apparatus 1, in particular in the housing 11 source 2 current and has not been installed, as shown in figure 1, as the attachment on the truck 12. However it is also possible that the mechanism 8 feed wires which can be installed directly on the welding apparatus 1, that is, the housing 11 source 2 current is made on the upper side for placement mechanism 8 wire, so you may not want to use the truck 12. To install the mechanism 8 wire feeder has a lever 23.

It is also possible that through the mechanism of the 8 wire serves welding wire 9 or filler material to carry out the welding torch 7, and in the welding torch 7 in the preferred embodiment, is a consumable electrode, which is typically used when welding with a consumable electrode inert gas welding with non-consumable electrode in an atmosphere of active gas.

The current to the arcing 13, in particular the working of an electric arc between the electrode or welding wire 9 and performed in the preferred embodiment, one or more parts of the workpiece 14 through not illustrated welding line is served from item 3 of the power source 2 current, the welding torch 7, in particular to the electrode or welding wire 9, and weldable workpiece 14 through another welding line for another capacity, in particular through the mass of the cable is connected with a not shown source 2 current and, thus, by means of an electric arc 13 or formed plasma jet for domestic the process can be formed in a current loop. When using a burner with an internal electric arc 13 both not illustrated welding line connected to the burner so that the burner can be formed corresponding to a current loop, as can occur when using plasma burners.

For cooling the welding torch 7 through the cooling apparatus 15 of the welding torch 7, with the intermediate connection possible additional components, for example, relay control flow from the reservoir for the liquid, in particular a tank 16 for water, can be connected to the sensor 17 level, resulting in actuation of the welding torch 7, the cooling device 15, in particular, is used to located in the tank 16 for liquid water, liquid ring vacuum pump is actuated, which may contribute to the cooling of the welding torch 7. As shown in the present embodiment of the invention, the cooling device 15 is mounted on the carriage 12, which is then placed source 2 current. The individual components of the welding installation, namely a source 2 current mechanism 8 wire feed and the cooling device 15 made this so that have corresponding protrusions or recesses, so that you can securely be placed or installed at each other.

Welding machine 1, in particular East is CNIC 2 DC, has the next device 18 input and output of information, through which can be configured to be invoked and displayed a variety of welding parameters, operating modes or welding programs welding apparatus 1. When this is configured through device 18 input and output information of the welding parameters, operating modes and welding programs are transmitted to the control device 4, and with his help, then configure the individual components of the welding machines or welding apparatus 1, or to set the appropriate parameters adjustment or control. However it is also possible that when using the appropriate welding torch 7 can also be taken and setting operations through the welding torch 7, and for this purpose the welding torch 7 is equipped with a device 19 input and output information. In the preferred embodiment, when the welding torch 7 via the data bus, in particular a serial data bus, is connected with the welding apparatus 1, in particular from a source 2 current or mechanism 8 wire feeder. To start the welding process, the welding torch 7 is in most cases not depicted trigger switch, so that by actuation of the starting switch may be produced by the ignition of the electric arc 13. For protection from the strong, those who viewed the radiation of the electric arc 13 it is possible to equip the welding torch 7 with a heat shield 20.

In the present example of the invention, the welding torch 7 through the package 21 of the sleeve further connected with the welding apparatus 1 or with welding installation, and the package 21 of the sleeve through the device 22 protection under longitudinal bending mounted on the welding torch 7. In the package 21 sleeveless single wires, for example the supply bus or wire for welding wire 9, to gas 5, for cooling circuit, data, etc. are from the welding device 1 to the welding torch 7, while the mass of the cable in the preferred embodiment, a specially attached to the source 2 power. The package 21 of the sleeve by means not illustrated coupling device is attached to the source 2 power or mechanism 8 wire, while the individual wires in the bundle 21 of the sleeve through a protection device for longitudinal bending mounted on or in the welding torch 7. To ensure a corresponding reduction in tensile stress of the package 21 of the sleeves this package by means not illustrated devices for reducing tensile forces can be connected to the housing 11 source 2 current or mechanism 8 wire.

In principle, it should be mentioned that for a variety of welding methods or welding apparatus 1, for example machines for TIG welding (tungsten is a diversified) inert gas or apparatus for welding with consumable electrode inert gas welding consumable electrode in an atmosphere of active gas, or apparatus for welding arc plasma should be used or not be used all the previously mentioned components. It is possible, for example, that the welding torch 7 can be made in the form of a welding gun, air cooled, so that, for example, you can refuse the use of the cooling device 15. Thus, we can say that the welding apparatus 1 is formed at least by a source 2 current mechanism 8 wire feed and the cooling device 15, and they can be located in a common housing 11. Then it is possible that it can be, respectively, used and other elements or components, for example a support 24 for additional elements, a holder 25 for gas cylinder 6 and so on

Accordingly, the prior art generally known that the welder to welding in inert gas or welding in the environment of the active gas needed, at least, of the welding apparatus 1, the mechanism 8 wire and the package 21 of the sleeve with a welding torch 7. Many options for use, for example, in the shipyards, or when working on a construction site, welding machine 1 set is its consequences on the protected site, so the welder is in the workplace, mainly with the mechanism 8 wire feeder and welding torch 7. This package 21 of the sleeve, respectively, attached to the mechanism 8 wire and 8 wire feeder connected to the welding apparatus 1. From this it follows that by means of the positioning mechanism 8 wire and the length of the package 21 of the sleeve defined by the dimensions of the workplace. If, in accordance with this, the weld must be made outside the workplace, the location mechanism 8 wire feeder should be changed. In practice, this occurs in such a way that the welder pulls the package 21 of the sleeve or the welding torch 7, so that the mechanism 8 wire feed has moved past it. It is possible, accordingly, up until the wire - connecting mechanism 8 wire with the welding apparatus 1 is natjanutoi mechanism 8 wire feed is not changed their position undesirable way, he in the preferred embodiment, is located on established stands, and not on rollers. When this bearing surface counters in most cases made of rubber. As a result, changing the location of the mechanism 8 wire by pulling the package 21 of the sleeve, it is necessary to overcome a certain frictional resistance between Nam the future and racks mechanism 8 wire, moreover, the mechanism 8 wire feeder may be slightly tip over and continue, in accordance with figure 2 is pulled to the side wall of the housing 26. The housing 26 of the mechanism 8 wire thus be broken.

Therefore, in accordance with the invention provides that the housing 26 can be mounted device 27 protection when moving. For this purpose, the device 27 protection when moving formed by the plate 28, which on the outer side 29 or on the side facing to the protected enclosure 26 has at least two elevation 30 to reduce the contact surface and resistance to friction. Each elevation forms a surface 31, and connected to the device 27 protection when moving the housing 26 adjacent to these surfaces 31 and can be moved without damage to the shell 26. The housing 26 can be moved in the direction in which the welder pulls the package 21 of the sleeves.

In detail, the device 27 protection when moving in accordance with the invention is described based on figure 2-8.

Figure 3 presents the device 27 protection when moving, which is fixed on the side of the mechanism 8 wire feeder. The outer side 29 forming device 27 protection when moving plate 28 has several elevations of 30 to reduce the contact surface and the resistance is possible friction. Exaltation 30, respectively, protrude above the plate 28. The location of the elevations 30 are selected so that the housing 26 can be moved in the preferred direction without a lot of resistance to friction. The housing 26 and, accordingly, the mechanism 8 wire feeder can be, thus, through the device 27 protection when you move, stretch out on the floor or moved. In addition, the location is chosen so that the housing 26 can be positioned stably. As an example (as shown in the drawing) of elevation 30 are located along the length of the plate 28, so that formed the so-called contact runners 32. Contact the runners 32 are mostly parallel to each other and, respectively, touch the floor. Between the contact rails 32 provided hereinafter defined gap 33 so, and due to this, minimizing the resistance to friction. Because the package 21 of the sleeve mounted on the end of a longitudinal side of the plate 28, that is, on the front side of the mechanism 8 wire feeder, the runners are in the direction of the package 21 of the sleeve. Thus, the housing 26 is moved in the direction of the package 21 of the sleeves, if reaching for him.

If the housing 26 with its Foundation tipped onto the contact rails 32, it can easily be moved. Thus the case is not damaged, but due to the greatly reduced resistance, good discharge performance the I friction load on the connection between the package 21 and sleeve mechanism 8 wire is held at a minimum value. Thus, when positioning in the workplace mechanism 8 wire feeder is mounted on the contact rails 32 device 27 protection when moving, so that the housing 26 further, if required, can be podtacular the fact that through the contact rails 32 sets the direction of movement of the housing 26, also prevents an undesirable change of location, as when pulling up or move perpendicular to the contact rails 32 have higher resistance to friction. Additionally runners 32 allows simple change of direction at the request of the welder, as the plane fit is very small. Contact the runners 32 may be tapered, semi-circular or similar cross section, by which the resistance to friction is further reduced.

The fixing device 27 protection when moving is on the inner side 34 or converted to the protected enclosure 26 of the side plate 28, on which are the appropriate means 35 is mounted. For example, as a means of 35 attachment used hinges and locking mechanism 36. When the hinge is fixed mainly on the base plate of the housing 26 on which is also fixed and hours, that is at the bottom. Accordingly, the clamping mechanism 36 is located on the above, for example, accumulation drum 10, so that the device 27 protection when moving can be tilted. When this hinge device 27 protection when moving mirror each other so that the device 27 protection when moving can be fully open. This means that the device 27 are sewn when moving forms, basically, one line from the bottom plate of the housing 26.

The tilting device 27 protection while moving enables simple connection of the supply lines (gas, current, data, air, etc.) welding device 1, due to improved availability. This is necessary because the connecting elements 37 to the inlet lines are mainly located under the arm mechanism 23 8 wire - that is, mainly in the centre. Simultaneously, these connecting elements through the device 27 protection when moving protected as moving and stationary housing 26.

Due to the possibility of tilting can be used clamping mechanism 36, through which the device 27 protection when moving can be fixed at a certain angle. Thus, the welder in a universal manner to cause the device 27 protection when moving in accordance with the terms and conditions in the workplace.

All device 27 protection when moving in General can the t to be however, for example, through multiple clamping mechanisms 36 fixed to the body 26, so that the device 27 protection when moving can be mounted on the housing 26. The fixing device 27 protection when moving in the preferred embodiment, is made detachable, so that the device 27 protection when moving can be quickly and simply replaced. For example, replacement is required when the elevation of the runners 32 are erased and become indistinguishable.

Of course, that can be replaced only contact the runners 32, if they are connected to the plate 28 with the possibility of the connector. Plug connection contact of the runners 32 and plate 28 may be implemented, for example, by means of screw connections or connectors. It also has the possibility of making contact rails 32 of a material different from material of the plate 28. Thus, the contact rails 32 can be, for example in accordance with the condition of the floor.

The possibility of fixing device 27 protection is also not limited to the fastening on the side wall of the housing 26. The device 27 may be secured on the base plate or the cover 26. In a preferred embodiment, the device 27 protection is mounted on the lateral side of the housing 26 in which is located the center of gravity of the housing 26. Those who amym guaranteed what if you move the danger of revolution minimal.

In a preferred embodiment, the shape of the device 27 of protection are provided in accordance with the shape of the side wall of the housing 26 on which it should be fixed. Because of this, the appearance is also largely unchanged. This ensures that the housing 26 is stably located on the device 27 protection. To ensure this stability, in the presence of a small size, the device 27 protection, of course, can be made more housing 26. Depending on needs, the device 27 of the protection can be done, of course, and less housing 26, or may have a shape other than the shape of the hull 26.

For example, the device 27 protection allows you to continue to implement a very simple replacement of the accumulating drum 10 mechanism 8 wire, because it can be produced not in the side and from above.

Of course, on the left side wall, right side wall and the bottom of the base plate of the housing 26, respectively, can be installed on one device 27 protection when moving. Thus, the housing 26 can be displaced, mainly in any position without damage. Accordingly, two side walls and the base plate can also be used on a single device 27 protection when PE is Emesene.

The device 27 protection when moving can be mounted on the side of the chassis 11 of the welding apparatus 1 or source 2 current. This variant of the fastening takes place, for example, in the so-called welding apparatus with electrode wire, in which there is no need to use mechanism 8 wire.

In conclusion, we can say that through the use of the device in accordance with the invention creates the possibility to move the housing 26 or the housing 11 to the floor without damage when this housing 26. No obstacles on the floor also does not represent a problem, as can be held between the contact rails 32.
