Abstract

The invention discloses a steel plate splicing welding joint bottom-surface ceramic liner lifting device and an operation method thereof. The device comprises a lifting hanging rack, a lifting device body and a liner bracket, wherein the lifting hanging rack is mounted on the upper surface of welded steel plates; the lifting device body is fixedly connected with the lifting hanging rack and penetrates through a steel plate welding joint; the liner bracket is mounted at the bottom of the lifting device body; and the lifting device body comprises pulley blocks each provided with a self-locking device. By means of the method, a liner is lifted to a welding joint plate bottom position to be put in place from the ground (floor) surface through the lifting device body, is fixed through the self-locking devices and then is mounted at the highly-aloft surface steel plate welding joint, so that welding joint backing weld operation is guaranteed, the mounting efficiency of the liner is improved, the operation difficulty is lowered, the construction cost is reduced, and the construction safety is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to welding of steel structures and bottoming welding of weld seams, and in particular to a lifting device for ceramic liners suitable for the bottom surface of steel plate splicing weld seams and an operating method thereof. Background technique [0002] With the development of modern technology, steel structure welding is more and more widely used in the field of building construction. In the actual welding process, to ensure the welding quality of the flat weld of thick members, especially in the process of back welding, the ceramic liner on the bottom of the weld is the main measure to ensure the quality of the back welding. However, in the actual installation process of the ceramic liner at the bottom of the high-altitude panel, there are technical problems such as large workload, low efficiency and high risk of high-altitude operations in setting up auxiliary faci...
