Clamping and fixing device for large caliber steel pipe

Abstract

The invention discloses a clamping and fixing device for a large caliber steel pipe. Long strip-shaped through holes are formed in two side plates of a clamping frame plate in the vertical direction;lateral threaded rods are perpendicularly inserted in the long strip-shaped through holes; the lateral threaded rods are locked and fixed to side panels of the clamping frame plate through locking nuts I; lateral propping plates are fixedly connected to the tail ends of the lateral threaded rods; a top threaded rod is perpendicularly inserted in the middle position of a top plate of the clamping frame plate; the top threaded rod is locked and fixed to a top panel of the clamping frame plate through a locking nut; a top propping plate is fixedly connected to the tail end of the top threaded rod; one end of the large caliber steel pipe is inserted in the clamping frame plate; the lateral propping plates on the two sides and the top propping plate at the top end prop against the external wallof the large caliber steel pipe to clamp and fix the large caliber steel pipe. According to the clamping and fixing device for the large caliber steel pipe, by using the technical scheme, the structure is simple, the assembling, connecting and mounting are convenient, the clamping and fixing device can be suitable for propping against steel pipes with different specifications and calibers, and the application range is wider.

Description

Technical field [0001] The invention relates to a clamping and fixing device for large-diameter steel pipes, which is applied to the technical field of large-diameter steel pipe clamping. Background technique [0002] Large-diameter steel pipes can be used in underground pipelines, oil, natural gas, steam heating, hydropower stations, sewage treatment plants, thermal power plants, water supply and drainage, etc. The large-diameter steel pipe needs to be clamped and fixed by a clamping device during the production process, which is convenient for cutting or gas cutting operations. After the production is completed, the clamping device also needs to be clamped and transported. However, the existing large-diameter steel pipe The clamping device is only suitable for clamping of one specification of pipe diameter, and its application range is narrow. For this reason, we design a clamping fixture for large diameter steel pipe. Summary of the invention [0003] In order to solve the def...

Problems solved by technology

Large-diameter steel pipes need to be clamped and fixed by clamping devices during the production process, which is convenient for cutting or gas cutting operations. After the production is completed, clamping devices are also required to clamp and transport them. The clamping device is only suitable for one type of pipe diameter clamping, and its application range is relatively narrow. Therefore, we design a clamping and fixing device for large-diameter steel pipes
