Abstract

Device for prestressing the guide groove of welding machines when welding vertical, inclined walls and ceilings, characterized in that the respective stand consists of a base plate in which slides or rollers are built in. Furthermore, a stand with a device for extracting the force necessary for prestressing the guide groove is built into it. A control device for checking the prestress is placed on the stand. The stand is provided with side struts for capturing lateral forces. A guide rail for inserting a mobile welding machine is further fixed to the base plate, ■■caught in a movable frame for capturing the reaction from the device for extracting the force necessary for prestressing the guide groove, which «e at the upper end rests on a movable frame. . The device for prestressing the guide groove can be used in mechanical engineering and construction, especially in the nuclear program.

Description

. BACKGROUND OF THE INVENTION The present invention relates to a device for prestressing the guide groove of welding machines for welding vertical, inclined walls and ceilings.

According to the state of the art, the grooves for guiding the welding machines are stitched to the weldment by 15 to 20 cm. When welding stainless steel or other vessel material for use in the nuclear and other industries, the existing guide grooves cannot be used because they have to be stitched, which is usually prohibited due to the difficulty and in most cases the inability to perform stitch check when fixing the groove. as there is a risk that the stitch may cause distortion or weaken the weldment material.

The above-mentioned disadvantages are eliminated by the invention, which consists in that the mobile stand consists of a base plate in which the slides or rollers are incorporated, and in addition a built-in stand with a device for applying the force necessary for preloading the guide groove.

The preload control device is located on the stand. The stand is equipped with side struts to absorb the lateral forces. A guide groove is also attached to the base plate for the deployment of a mobile welding machine. The other end of the guide groove is mounted in the movable arm to receive the reaction from the device for exerting the force required to bias.

The advantage of the solution according to the invention is that the productivity of the work and the improved welding of sawdust, both stainless steel and others, are improved, because otherwise it would not be possible. The guide groove and the biasing device form one assembly which can be easily and quickly displaced.

. An exemplary embodiment of a groove biasing device according to the invention is shown in the attached drawing, where the figure is a side view.

An example of a device for generating a preload of a guide groove is an icon assembly consisting of a preloaded guide groove 1, which is embedded in the bottom of the base plate 2 and is mounted at the top in a movable arm 3 which receives reactions from the deriving device 4 the forces required to bias the guide groove 1 and the stand 5.

The movable frame 3 is supported on the supports 6. For the lateral forces, the stand 5 is provided with lateral or lateral struts 7. On the stand there is a device 4 for pre-fitting five guide grooves 1, which can be mechanical or hydraulic. The control device 8 is used to check the preload. A mobile welding machine 9 is mounted on the guide groove 1.

The preloading device of the guide groove 1 according to the invention operates in such a way that the stand 5 is fastened to the base plate 2, which is also fastened with the guide groove 1 and a support 6 or supports absorbing the lateral forces generated by the device 4. to preload the guide groove 1, which rests on the upper end on the movable arm 3. The armrests 6 are fastened to the arm 3.

Welding Vertical, sloping walls and ceilings with automatic welding machines can be used for welding stainless and possibly other materials in the nuclear industry, especially in the production of warehouses and miezis depots of spent fuel, in welding of tanks and the like.
