Abstract
The utility model discloses a protection device of a shield tunneling machine cutter head. The protection device of the shield tunneling machine cutter head comprises a cutter head (2) which is installed at the front end of a shield tunneling machine (1). A wear resistant plate (3) which is attached to an inner edge and an outer edge of the cutter head (2) is paved on the cutter head (2), screw holes (4) which are communicated with each other are formed in the wear resistant plate (3) and the cutter head (2), and the wear resistant plate (3) and the cutter head (2) are fixed into a whole through a bolt which penetrates through the screw holes (4). The protection device of the shield tunneling machine cutter head is simple in structure and convenient to use. The protection device of the shield tunneling machine cutter head can be changed quickly at the construction site when the wear resistant plate abraded to a certain position is discovered, so that maintenance time is greatly reduced, and working efficiency is improved.
Description
Technical field
The utility model relates to shield machine processing and manufacturing field, is specifically related to a kind of cutter head of shield machine protective device.
Background technology
Cutterhead in shield machine adopts monomer structure to be made mostly at present, because its whole abrasion resistance of reason of its residing working environment is relatively poor, and wearing and tearing are all from the edge of cutterhead, in order to solve this phenomenon, usually the way that adopts is to carry out built-up welding processing at the edge of cutterhead, although extended to a certain extent its whole application life, but after reaching the cutterhead body in case wear and tear, often all need shield machine is withdrawn from, and then built-up welding, not only affected the efficient of driving, and higher to quality and the technological requirement of welding.
The utility model content
The utility model purpose is to provide a kind of cutter head of shield machine protective device, and it can solve existing problem in background technology effectively.
In order to solve existing problem in background technology, it comprises the cutterhead 2 that is arranged on shield machine 1 front end, be equipped with the wear plate 3 of its interior outer edge of fitting on this cutterhead 2, offer the screw 4 that communicates on this wear plate 3 and cutterhead 2, bolt passes screw 4 wear plate 3 and cutterhead 2 is fixed into one.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, can carry out at the construction field (site) quick-replaceable when finding that wear plate may wear to certain position, reduce greatly the time of maintenance, increased operating efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is done simple introduction.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment is clearly and completely described the technical scheme in the utility model embodiment.
Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, it comprises the cutterhead 2 that is arranged on shield machine 1 front end, be equipped with the wear plate 3 of its interior outer edge of fitting on this cutterhead 2, offer the screw 4 that communicates on this wear plate 3 and cutterhead 2, bolt passes screw 4 wear plate 3 and cutterhead 2 is fixed into one.
Owing to having adopted above technical scheme, this specific embodiment has following beneficial effect: simple in structure, easy to use, can carry out at the construction field (site) quick-replaceable when finding that wear plate may wear to certain position, reduce greatly the time of maintenance, increased operating efficiency.
