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...

Abstract
The invention discloses a cross sliding roof type liner device for pipe welding, and mainly aims to provide a liner device capable of being applied to medium / small-caliber pipe welding construction. The device is characterized by comprising a front support cylinder, a cross slide frame, small arc liners, large arc liners, a split slide way, a slide way blockage plate, a dowel pin, a slide way screw, a nut, a slide way spring, a guide wheel base, a small guide wheel, a small pin shaft, a long connecting cylinder, a push-pull rod, a slide frame screw, a push-pull handle, a wear reducing ring, alocking head, a locking spring and a fixed handle, wherein four arc liners are adopted to replace multiple massive liners for blockage. The liner device is smaller in radial size, can be applied to the small-caliber pipe welding, is simpler in structure and more convenient to operate, can improve the welding efficiency, and in addition, can be provided with the guide wheels to achieve a pipe orifice aligning function.
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...
