Embodiment Construction
[0039] The present invention will be further described below in conjunction with accompanying drawing:
[0040] Depend on Figure 1 to Figure 21 As shown, the device consists of: front support cylinder, cross carriage, small arc liner, large arc liner, split slideway, slideway blocking plate, positioning pin, slideway screw, nut, slideway spring, guide Wheel seat, small guide wheel, small pin shaft, long connecting cylinder, push-pull rod, carriage screw, push-pull handle, wear-reducing ring, lock head, lock spring, fixed handle.
[0041] The front support cylinder is a short cylinder for supporting the front of the device; the rear end surface of the front support cylinder is flange-shaped, and is connected with the front flange of the long connecting cylinder through slideway screws.
[0042] The cross carriage is a cross-shaped sliding body, and the four cross-shaped ribs are divided into two groups, the upper and lower ribs form a group, and the left and right ribs form a...

The utility model relates to a cross-sliding top pad device for pipeline welding. The main purpose of the utility model is to provide a liner device that can be applied to the welding construction of small and medium-diameter pipelines. It is characterized in that: the device includes a front support cylinder, a cross carriage, a small arc liner, a large arc liner, a split slideway, a slideway blocking plate, a positioning pin, a slideway screw, a nut, a slideway spring, a guide Wheel seat, small guide wheel, small pin shaft, long connecting cylinder, push-pull rod, carriage screw, push-pull handle, wear-reducing ring, lock head, lock spring and fixed handle; among them, four arc-shaped gaskets are used to replace Multiple block liners for sealing. This kind of liner device has a small radial dimension and can be applied to the welding of small-diameter pipes. It has a relatively simple structure and is very convenient to operate, which can improve the working efficiency of welding. In addition, it is equipped with guide wheels to realize the function of pipe matching.
Description
technical field [0001] The invention relates to a liner device for pipeline welding. Background technique [0002] The application of welding backing can greatly improve the welding quality. At present, pipe welding counterparts with gasket parts have been developed at home and abroad, and the gasket technology is applied to the welding process of large-diameter pipelines. However, due to the narrow radial space, small and medium-diameter pipes cannot be fitted into pipe welding counterparts with complex structures. Therefore, in the welding process of small and medium-diameter pipes, there is no mature liner device application. Contents of the invention [0003] In order to solve the technical problems mentioned in the background technology, the present invention provides a cross-sliding top liner device with a small radial dimension, which can be applied to the welding construction of small and medium-diameter pipelines. The liner device has a simple structure and is e...
