Steel pipe parallel lifting and moving loading and unloading device

Abstract

The invention discloses a steel pipe parallel lifting and moving loading and unloading device which comprises two sets of driving mechanisms connected through a high-strength chain, a driving mechanism body comprises a first driving chain wheel and a second driving chain wheel which are installed at the upper end and the lower end, and the two ends of the high-strength chain are hung on the first driving chain wheel and the second driving chain wheel respectively. Compared with the prior art, the device has the advantages that the efficiency is greatly improved, the situation that products fall to the ground and then are transferred is reduced, the production cost is greatly saved, automatic operation is achieved in the whole process, manpower is saved, secondary pollution to the environment is avoided, and the device is wide in application range and can be used for metal pipes and non-metal pipes; the device is compact in structure, firm in connection, convenient to manufacture, install and overhaul, few in used material, little in welding and machining, safe, reliable, small in size and light in weight, and overlarge power load cannot be generated; the welding amount is small, machining is convenient, the manufacturing cost is low, the good popularization prospect is achieved, the part interchangeability is good, and part interchangeability can be achieved according to the actual situation.

Description

technical field [0001] The invention relates to the field of steel pipe production, in particular to a steel pipe parallel lifting mobile loading and unloading device. Background technique [0002] China is a big country of steel pipes. In 2014, China's steel pipe output was 88.98 million tons, accounting for 54% of the world's 165 million tons; among them, the output of welded steel pipes was 57.61 million tons, accounting for 50% of the world's 115.6 million tons of welded steel pipes; 63.56% of the 49.35 million tons of seamless steel pipes; but China cannot be called a steel pipe powerhouse, because we still have a certain gap with some advanced enterprises in product quality and variety innovation (Turner, Vallourec, Sumitomo, Kawasaki, Hyundai), we must speed up the pace of progress and march towards the world's steel pipe power. [0003] The advancement of welding technology and the improvement of plate quality have enabled welded pipe products to further replace som...
