Abstract
A fast-replacing-type tunnel boring machine (TBM) main drive sealing device comprises a cutter disc, an outer seal, an outer ring, a main bearing, a main drive casing, a reducer, a driving motor, a coupler, an inner ring, a large gear ring, an inner seal, a small gear and an adaptation ring. A main drive provides rotating power through the driving motor and the reducer and is fixedly connected with the coupler on the main drive casing, the small gear is meshed with the large gear ring, one side of the adaptation ring is connected with the large gear ring, the other side of the adaptation ring is connected with the cutter disc, and the main bearing for support is connected in the middle of the adaptation ring. The device is applied to a TBM shield machine main drive portion, adopts a four-claw-type lip-shaped sealing ring, and is reasonable in sealing structure design. By means of the matched unique design of an inner sealing structure and an outer sealing structure, the inner seal and the outer seal of the TBM shield machine main drive are convenient to detach, and seal replacement is very convenient.
Description
Technical field
A kind of quick-change type TBM driving owner that the utility model relates in TBM development machine field drives sealing device.
Background technology
Main driving is the important component part of various types of TBM tunnel machines such as soil pressure, muddy water, hard rock, for cutterhead rotation provides power.And sealing is one of core texture of main driving; its driving gear pair to base bearing and main driving plays seal protection effect; because the construction environment of TBM shield machine is very complicated; in the time of need to changing if the sealing of main driving is damaged; in tunnel, due to factors such as spatial limitation, make difficult sealing to change.Often need excavating shaft, then change sealing, operating difficulties not only, and waste time very much, consume huge cost.When sealing has just been changed in the main driving of TBM shield machine, need to dismantle cutterhead, and cutterhead is removed to larger distance, for dismounting provides space, operate very complicatedly, spend huge.So the reliability of sealing is the normally key factor of smooth construction of TBM shield machine equipment.If can there be a kind of hermetically-sealed construction can solve the replacing problem of sealing, for the reliability that improves TBM shield machine, great meaning will be had so.Therefore, researching and developing a kind of quick-change type TBM driving owner, to drive sealing device be new problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is to provide a kind of quick-change type TBM driving owner and drives sealing device, this application of installation is in the main drive part of TBM shield machine, adopt four-jaw type lip-type packing, rational design of Sealing Structure, coordinate unique inside and outside two seals structure design, make in the main driving of TBM shield machine sealing and the external seal can be for convenience detach, make the replacing of sealing become very convenient.
The purpose of this utility model is achieved in that a kind of quick-change type TBM driving owner drives sealing device, comprise cutterhead, external seal, outer shroud, base bearing, main drive shell, reductor, drive motors, shaft coupling, interior ring, bull gear, interior sealing, pinion, adapter ring, main driving provides rotary power by drive motors and reductor, be fastened in main drive shell with shaft coupling, pinion and bull gear engagement, adapter ring one side is connected with bull gear, adapter ring opposite side is connected with cutterhead, in the middle of adapter ring, connect the base bearing providing support, interior sealing, external seal, interior ring, outer shroud, the main driving hermetically-sealed construction that the common formation of main drive shell is isolated from the outside.
Main points of the present utility model are its structure.Its operating principle is that the utility model patent adopts a kind of hermetically-sealed construction of quick-change type, while sealing in changing, can dismantle cutterhead, completes efficiently rapidly more changing jobs of interior sealing.And when changing cutterhead external seal, also only need to drive 50mm-60mm distance separated with cutterhead can realize the replacing of external seal.While sealing in the main driving replacing of TBM cutterhead, only interior ring need be disassembled, then change.When changing external seal, need to dismantle cutterhead, but only cutterhead need be moved to 50-60mm, outer shroud can be dismantled, then change external seal.While sealing in the main driving replacing of TBM cutterhead, only interior ring need be disassembled, then change.Main driving provides rotary power by drive motors 7, is connected with shaft coupling, drives pinion rotation.When electric motor starting, cutterhead 1 is rotary work thereupon.Interior sealing and external seal, with interior ring and the common hermetically-sealed construction that forms main driving of outer shroud, are isolated from the outside main driving cavity, prevent from entering impurity.
A kind of quick-change type TBM driving owner drives sealing device compared with prior art, have be applied to the main drive part of TBM shield machine, adopt four-jaw type lip-type packing, reasonably design of Sealing Structure, coordinate unique inside and outside two seals structure design, make in the main driving of TBM shield machine sealing and the external seal advantage such as very convenient that can replacing for convenience detach, that make sealing becomes, will be widely used in TBM development machine field.
Accompanying drawing explanation
