A movable assembly room and assembly method of a disc hob

Abstract

The invention discloses a disc-shaped hob removable assembly chamber and assembly method and relates to the technical field of disc-shaped hob assembly. A washing device, an electrical oven, a hydraulic machine, an air compressor and a detection platform are fixed to a bottom plate of a container, and an electric welding machine is movably arranged on the bottom plate of the container; a rotary shaft is vertically arranged on the bottom plate of the container, the top penetrates the container, one ends of a first cantilever and second cantilever are hinged to the rotary shaft, the first cantilever is located in the container, the second cantilever is located outside the container, and the hydraulic machine and the detection platform are located below the rotating range of the first cantilever. The assembly method includes utilizing the washing device to wash parts, utilizing the hydraulic machine to assemble the parts to form a disc-shaped hob body, utilizing the air compressor to detect the tightness, and utilizing the electric welding machine to welding a retaining ring, and obtaining a product. The disc-shaped hob can be assembled on the construction site, and the assembly process is simple and labor saving.

Description

technical field [0001] The invention relates to the technical field of assembly of disc-shaped hobs, in particular to a movable assembly room and an assembly method of disc-shaped hobs. Background technique [0002] During the excavation of the subway tunnel by the shield machine, the disc-shaped hob on the cutter head (hereinafter referred to as the hob) is a vulnerable part, which often needs to be replaced and repaired. Such as figure 1 As shown, the disc hob includes a mandrel 95, and two bearings are sheathed on the mandrel 95. Each bearing includes a bearing inner ring 91 and a bearing outer ring 92, and a cutter hub 94 is sheathed outside the two bearings. The upper and lower ends of 94 are respectively provided with end caps 97, the mandrel 95 runs through the end caps 97 at both ends, the middle part of the outer ring of the cutter hub 94 is sleeved with a cutter ring 93 and a retaining ring 96, and the retaining ring 96 is welded together with the cutter hub 94, ...

AI Technical Summary

Problems solved by technology

When the hob is being repaired, the tunneling work of the shield machine will stop, and the assembly will take a long time period, which will delay the construction period and increase the construction cost

In addition, the construction site is constantly changing, and the construction site space is limited, and the factory hob assembly room and related equipment cannot be set up and installed

Moreover, when the hob is assembled, it is necessary to move the hob continuously inside and outside the assembly room, but the weight of the hob is greater than 150kg, and it is impossible to set up factory lifting equipment on the construction site, which leads to inconvenience in on-site operation
