Problems solved by technology

[0002] There are a large number of loose tubes and rows in the components of the boiler department. The tube rows need to be lifted and turned over during the tailor welding process. At present, the production workshop is accustomed to using simple lifting locks such as hooks for lifting and turning. Using this method is easy to damage the tube rows , and the pipe row is easy to slip during the hoisting process, and there is a big hidden danger of accident

Abstract

The invention provides a lifting device for horizontal tube banks. The lifting device is characterized in that the lifting device comprises a clamping block and a fastening block or fastening strip, the fastening block or fastening strip is positioned on the upper portion of the clamping block, a first connection block is connected to the middle of the clamping block, the first connection block and a press rod are connected through a first hinge pin and a first split pin, a positioning strip is arranged on the upper side of the lower portion of the clamping block, the press rod is arranged above the positioning strip, and the horizontal tube banks are arranged between the press rod and the positioning strip. The lifting device has the advantages that aiming at banks of separate tubes in boiler components, tube bank lifting and overturning speeds can be increased effectively by the lifting device; meanwhile, mechanical damage to tube bank lifting ends due to use of tools such as lifting hooks is avoided during lifting, and large-scale application of the lifting device in production workshops is facilitated.

Description

technical field [0001] The invention relates to a horizontal pipe row lifting device. Background technique [0002] There are a large number of loose tubes and rows in the components of the boiler department. The tube rows need to be lifted and turned over during the tailor welding process. At present, the production workshop is accustomed to using simple lifting locks such as hooks for lifting and turning. Using this method is easy to damage the tube rows , and the pipe row is easy to slip during the hoisting process, and there is a greater hidden danger of accidents. Contents of the invention [0003] The object of the present invention is to provide a horizontal pipe row lifting device. [0004] In order to achieve the above object, the present invention provides a horizontal pipe row lifting device, which is characterized in that it includes a clamping block and a clamping block or a clamping strip, and the clamping block or clamping strip is positioned on the upper p...
