Example Embodiment

[0043] Below in conjunction with accompanying drawing, invention will be further described:

[0044] Depend on Figure 1 to Figure 23 As shown, the device consists of: odd-numbered pads, even-numbered pads, odd-numbered elastic frames, even-numbered elastic frames, elastic frames, connecting cylinders, small guide wheels, small pin shafts, wheel brackets, pad expansion rings, and front support tubes , Stop ring, push-pull rod, hanger rod, front sliding sleeve, rear sliding sleeve, compression spring, auxiliary handle.

[0045] The liner used by the device to block the groove of the pipeline is composed of a plurality of block liners, and the material of the liner is ceramic or copper alloy. The odd pads and the even pads of the device are different in shape, and the two are installed in the same quantity, the odd pads are installed on the odd elastic frames, and the even pads are installed on the even elastic frames.

[0046] The odd-numbered gaskets are long and block-shape...

Abstract

The invention provides a push-pull expansion type gasket device for pipeline welding. The invention mainly aims at providing a push-pull expansion type gasket device with a relatively small radial size, which can be applied to welding construction of pipelines with small and medium calibers. The device is characterized by comprising odd gaskets, even gaskets, odd elastic frames, even elastic frames, an elastic frame seat, a connecting barrel, a small guide wheel, a small pin shaft, a wheel bracket, a gasket expansion spring, a front supporting barrel, a baffle ring, a push-pull rod, a gear engaging rod, a front sliding sleeve, a tail sliding sleeve, a compression spring and an auxiliary handle; the shapes of the odd gaskets and the even gaskets of the device are different and the quantities of the odd gaskets and the even gaskets are the same; the odd gaskets are mounted on the odd elastic frames; and the even gaskets are mounted on the even elastic frames.

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 push-pull tensioning type 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 ...
