Description
Technical field
The present invention provides a kind of novel support boots structure, belongs to shield-tunneling construction field.
Background technology
Support boots on shield machine are the important tools for segment assembly, its structure quality directly affects shield machine segment assembly
Work efficiency and job schedule.The mostly extra large RAKE architecture of the support boots structure of large-diameter shield machine currently on the market, its inside
Structure compares new support boots structure design：1st, structure is relative complex；2nd, it is relatively inconvenient to safeguard；3rd, production cost is high.As in
Patent Office of state discloses（CN105443135A）A kind of support boots structure of class rectangle shield driving oil cylinder, its front end are equipped with flexible board,
Rear end is connected by mounting screw with oil cylinder, is rigid push-and-pull during push-and-pull, and section of jurisdiction can be damaged during push-and-pull, permanent to use
Very big infringement can be caused to all parts of system afterwards, reduce the service life of system.If replacing internal screw needs to tear open
Except the top plate of front end, flexible board etc., it is very inconvenient to repair.
The content of the invention
The present invention solves above-mentioned technical problem and provides a kind of novel support boots structure, compact-sized simple, the easy to maintain, peace
Full measure is high, production cost is low, service life length, and excavating production for large-diameter shield provides stable guarantee.
The present invention solves the technical solution that technical problem uses：
A kind of novel support boots structure, including thrust holder structure, thrust holder structure rear end are equipped with bulb, bulb and extraneous push action cylinder
Connection, bulb are fixed on thrust base rear end by rear cover, and bulb front end is equipped with kingbolt, and thrust bearing structure front end has mesoporous,
Kingbolt stretches into mesoporous, and elastomer, gap between the kingbolt and thrust holder structure are equipped between kingbolt and thrust bearing
Coordinate, kingbolt can move back and forth under push action cylinder effect in regime of elastic deformation, and thrust bearing structure front end is equipped with thrust
Pad, thrust pad middle part are equipped with the through hole connected with mesoporous.
Above-mentioned through hole is equipped with gland, and thrust pad is not higher than for closing the mesoporous, and in preceding extreme direction upper press cover,
Avoid gland from touching and pushed away pipe of concrete on piece.
Above-mentioned elastomer is butterfly spring.
Covered after above-mentioned equipped with oil cylinder via, bulb is connected with extraneous oil cylinder, the rear cover is connected by bolt
It is connected on thrust holder structure.
Beneficial effects of the present invention：
1st, by being equipped with elastomer between kingbolt and thrust bearing, gap is matched somebody with somebody between the kingbolt and thrust holder structure
Close, kingbolt can move back and forth under push action cylinder effect in regime of elastic deformation, push-and-pull is had resiliency, it can be significantly
The service life of raising system, and reduce the damage to section of jurisdiction；
2nd, there is mesoporous by thrust bearing structure front end, kingbolt stretches into mesoporous, leads in the middle part of thrust pad equipped with what is connected with mesoporous
Hole, through hole are equipped with gland, are not higher than thrust pad for closing the mesoporous, and in preceding extreme direction upper press cover, avoid gland from connecing
Contact and pushed away pipe of concrete on piece, it can greatly improve the convenience of maintenance, and can seal extraneous dirt by gland setting
Body enters hollow interior, protects at kingbolt and elastomer and kingbolt and thrust bearing respective outer side edges.
3rd, butterfly spring has the wider characteristic of outside diameter, can be bent to avoid elastomer caused by the non axial push-and-pull of oil cylinder
And cause stuck elastomer.
4th, rear cover is connected by bolt with thrust holder structure, convenient dismounting.
Brief description of the drawings
Illustrated below in conjunction with attached drawing with embodiment
Fig. 1 is the structure diagram of the present invention.
Embodiment
Referring to the drawings 1, a kind of novel support boots structure, including thrust holder structure 5, thrust holder structure rear end are equipped with bulb 8, ball
Head is connected with extraneous push action cylinder, and bulb is fixed on thrust base rear end by rear cover 6, and bulb front end is equipped with kingbolt 2, thrust bearing
Structure front end has mesoporous 9, and kingbolt stretches into mesoporous, is equipped with elastomer 4 between kingbolt and thrust bearing, the kingbolt with
Clearance fit between thrust holder structure, kingbolt can move back and forth under push action cylinder effect in regime of elastic deformation, thrust
Holder structure front end is equipped with thrust pad 1, and the through hole 10 connected with mesoporous is equipped with the middle part of thrust pad.
Preferably, the through hole is equipped with gland, is not higher than for closing the mesoporous, and in preceding extreme direction upper press cover
Thrust pad, avoids gland from touching and is pushed away pipe of concrete on piece.
Preferably, the elastomer is butterfly spring.
Preferably, covered after described equipped with oil cylinder via, bulb is connected with extraneous oil cylinder, the rear cover passes through
It is bolted on thrust holder structure.
This support boots operation principle is：Under the promotion of push action cylinder, thrust is applied to by thrust holder structure and thrust pad
Pipe of concrete on piece；Under the pulling of push action cylinder, pulling force is by kingbolt and rear cover, under the buffering of disk spring, pushing away
The support boots gone out pull back.
Protection scope of the present invention is not limited to the above embodiments, it is clear that those skilled in the art can be to this hair
It is bright to carry out various changes and deformation without departing from scope and spirit of the present invention.If these changes and deformation belong to power of the present invention
In the range of profit requirement and its equivalent technologies, then including the intent of the present invention is also changed and deformed comprising these.
