Port fixture for steel pipe hoisting

Abstract

The invention discloses a port fixture for steel pipe hoisting. The port fixture for steel pipe hoisting comprises a motor cover, a connection cross rod, a fixing block and a second slide block, wherein a screw rod is rotationally installed at the middle position in the connection cross rod, four first slide grooves are symmetrically formed in the connection cross rod and around the screw rod, thesecond slide block is of a cross-shaped structure, and the middle position of the second slide block is in threaded connection with the screw rod; and the fixing block is fixedly installed at the right end of the connection cross rod, four slide rods are symmetrically installed around the fixing block, a slide sleeve is arranged on the slide rod, a second slide groove is formed in one end away from the fixing block, of the slide sleeve, a first slide block is slidably installed in the second slide groove, and a press plate is fixedly installed at the other end of the first slide block. According to the port fixture for steel pipe hoisting, the cross-shaped second slide block is driven to slide through the screw rod, so that the four slide sleeves are driven to slide; and the inner wall ofthe steel pipe is extruded and fixed through the press plate provided with anti-slide lines, so that the stability during the steel pipe hoisting is improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a port clamp for steel pipe hoisting. Background technique [0002] Steel pipes are used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes...

AI Technical Summary

Problems solved by technology

[0003] During the processing or transportation of steel pipes, lifting devices are always needed. Due to the cylindrical structure of steel pipes and the smooth surface of the inner and outer walls, it is difficult to lift steel pipes. The structure and function of existing lifting devices are too simple. It is difficult to effectively and stably fix the steel pipe, thereby increasing the difficulty of lifting the steel pipe, and at the same time bringing safety hazards to the staff on site
