A multi-layer pipe row hook

Abstract

The invention provides a multilayer tube row lifting hook which comprises a positioning hook, wherein a connection block is arranged on the positioning hook; a clamping wheel is arranged at the bottom of the positioning hook through a pin with a hole; a lifting hook is arranged on the connection block through the pin with the hole and is embedded into a groove in the end face of the clamping wheel. According to the device disclosed by the invention, the shortcomings in the prior art are overcome; a plurality of pipe rows can be simultaneously lifted and transported at a time, so that the pipe row lifting and transporting time is obviously shortened, and the production efficiency is improved; furthermore, the precision of placement positions between surfaces of the pipe rows can be guaranteed, and the subsequent transportation is facilitated; the multilayer tube row lifting hook can be matched with various specifications of clamping wheels. The multilayer tube row lifting hook has the advantages of high generality, small volume, low manufacturing cost and simplicity in loading and unloading and is favorable for large-scale use in a production workshop.

Description

technical field [0001] The invention relates to a multilayer pipe row hook, which belongs to the technical field of boiler pipe rows. Background technique [0002] At present, there are mainly two types of tube rows processed and formed by boilers, namely, loose tube tube rows and membrane type spliced ​​rows. For these two types of tube rows, most of the manufacturing workshops currently use a single hook for lifting operations. This lifting method consumes Time-consuming and labor-intensive, and the production efficiency is low. At the same time, the monolithic tube rows are superimposed and placed layer by layer, and the accuracy of the placement position between the tube row surfaces is not easy to guarantee, which will bring inconvenience to subsequent transportation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-layer pipe row hook that can significantly reduce the lifting time of the pipe row, i...
