Portal frame device for welding steel pipe piles

Abstract

The invention provides a portal frame device for welding steel pipe piles. The portal frame device comprises flexible smoke discharging pipes and smoke discharging switches, wherein the tops of portalframe main bodies are I-shaped sliding rail structures; six universal wheels are mounted on the bottom end surfaces, the front end surfaces and the rear end surfaces of the portal frame main bodies;a total of eight fixed thread shafts are respectively mounted on the bottoms of two portal frame main bodies; the tops of the fixed thread shafts are hexagonal blocky structures; a total of eight fixed support plates are arranged; two ends of steel pipe piles in the hung state are fixed; the staff can conveniently and stably carry out the operation of welding the steel pipe piles in the later period; the influence on the welding accuracy of the steel pipe piles caused when the steel pipe piles shake back and forth in the portal frame main bodies can be avoided; with cooperation of the clampingthread shafts and hand wheels, the clamping diameters of two clamping blocks can be adjusted, so that the two clamping blocks are more capable of fixing the steel pipe piles with different diameter specifications; the fixing effect in the device can be improved.

Description

technical field [0001] The invention belongs to the technical field of steel pipe pile welding, and more specifically relates to a gantry equipment for steel pipe pile welding. Background technique [0002] Steel pipe piles are suitable for foundations in the construction of wharves and ports. The diameter range is generally between 600-2000mm, and the most commonly used one is 1800mm. During the production process of steel pipe piles, a series of welding of steel pipe piles is required. However, due to the heavy weight of the steel pipe piles, the staff basically use professional gantry equipment to hang the steel pipe piles in order to carry out welding operations on the steel pipe piles. [0003] Based on the above, the inventor found through searching that similar gantry equipment exists, such as patent application number CN207361723U, the mentioned gantry belongs to the technical field of automation equipment. The gantry frame of the present invention includes a gantry...
