Problems solved by technology
Due to the inevitable human error, it is easy to cause uneven force on the seal installation, resulting in substandard sealing effect, or even falling off during use, which will directly lead to hob seal failure, lubricating oil leakage, and bearing damage. The hob is damaged and scrapped, which reduces the construction efficiency and increases the construction cost

The invention discloses a device for assisting in assembly of a sealing ring of a hobbing cutter of a shield tunneling machine, and relates to the technical field of hobbing cutter assembly. The device comprises a sealing tool. A shaft hole allowing a cutter shaft of the hobbing cutter to penetrate through is formed in the middle of the sealing tool, a flat force application face allowing external force application is arranged on one side of the sealing tool, and an annular protruding pressing platform part which corresponds to the floating sealing ring of the hobbing cutter and is used for pressing the floating sealing ring in the external force application state is arranged on the side, far away from the force application face, of the sealing tool and located on the outer side of the shaft hole. A protruding limiting part is arranged on the edge, far away from the shaft hole, of the protruding pressing part, and when the floating sealing ring is installed, the protruding limiting part is used for limiting the floating sealing ring inside. By the adoption of the technical scheme, specific nylon plastic is selected as a pressing cushion layer, abrasion, caused by the external force, of the metal face of the floating sealing ring can be avoided in the assembly process of the cutter, the man-made damage is reduced, and the mechanical fixing, assembling and pressing modes can be adopted so that the cutter sealing ring can be evenly stressed in the assembling process.
Description
technical field [0001] The invention relates to the technical field of hob assembly, in particular to a device for assisting the assembly of the hob sealing ring of a shield machine. Background technique [0002] With the continuous development of urban rail transit construction, the shield tunneling method has been more and more widely used due to its advantages of convenience, speed, safety and reliability. The cutter head cutter is the core component of the shield excavation system, and the cutter is one of the most direct structural components to realize the excavation function of the shield machine. Therefore, the maintenance and management of the shield cutter is of great significance. [0003] In the maintenance process of shield machine hob cutter, the installation of floating seal is one of the most critical steps, which directly affects the assembly quality and service life of internal components of the cutter body. In the traditional process, when the hob seal is...
