Description

A kind of novel support boots structure

Technical field

The utility model provides a kind of novel support boots structure, belongs to shield-tunneling construction field.

Background technique

Support boots on shield machine are the important tools for segment assembly, its structure quality directly affects shield machine assembly The working efficiency and job schedule of section of jurisdiction.The support boots structure of large-diameter shield machine is mostly extra large RAKE architecture currently on the market, it Internal structure is designed compared to novel support boots structure: 1, structure is relative complex；2, maintenance is relatively inconvenient；3, high production cost. If Patent Office of the People's Republic of China discloses a kind of support boots structure of (CN105443135A) class rectangle shield driving oil cylinder, front end is equipped with flexibility Plate, rear end are connect by mounting screw with oil cylinder, are rigid push-and-pulls during push-and-pull, section of jurisdiction can be damaged during push-and-pull, for a long time Very big damage will cause to all parts of system after use, reduce the service life of system.If replacing internal screw needs Top plate, the flexible board etc. of front end are removed, it is very inconvenient to repair.

Summary of the invention

The utility model solves above-mentioned technical problem and provides a kind of novel support boots structure, compact-sized simple, the maintenance side Just, safety measure is high, production cost is low, long service life, excavates production for large-diameter shield and provides stable guarantee.

The utility model 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 thrust Oil cylinder connection, bulb are fixed on thrust base rear end by rear cover, and bulb front end is equipped with kingbolt, during thrust bearing structure front end has Hole, kingbolt protrude into mesoporous, between kingbolt and thrust bearing be equipped with elastomer, between the kingbolt and thrust holder structure between Gap cooperation, kingbolt can be moved forward and backward under push action cylinder effect in regime of elastic deformation, and thrust bearing structure front end is equipped with and pushes away Power pad, thrust pad middle part are equipped with the through-hole being connected to mesoporous.

Above-mentioned through-hole is equipped with gland, is not higher than thrust pad for closing the mesoporous, and in preceding extreme direction upper press cover, It avoids gland from touching and is pushed away pipe of concrete on piece.

Above-mentioned elastomer is butterfly spring.

It is covered after above-mentioned equipped with oil cylinder via hole, bulb is enable to connect with extraneous oil cylinder, the rear cover is connected by bolt It connects on thrust holder structure.

The utility model has the beneficial effects that

1, by being equipped with elastomer, gap between the kingbolt and thrust holder structure between kingbolt and thrust bearing Cooperation, kingbolt can be moved forward and backward under push action cylinder effect in regime of elastic deformation, and push-and-pull is made to have resiliency, can be big The big service life for improving system, and reduce the damage to section of jurisdiction；

2, there is mesoporous by thrust bearing structure front end, kingbolt protrudes into mesoporous, is equipped in the middle part of thrust pad and is connected to mesoporous Through-hole, through-hole is equipped with gland, is not higher than thrust pad for closing the mesoporous, and in preceding extreme direction upper press cover, avoids pressing Lid, which touches, is pushed away pipe of concrete on piece, can greatly improve the convenience of maintenance, and can seal outside by gland setting Boundary's dirt body enters hollow interior, protects at kingbolt and elastomer and kingbolt and the cooperation of thrust holder structure.

3, butterfly spring has outer diameter than wider characteristic, can bend to avoid elastomer caused by the non axial push-and-pull of oil cylinder And cause stuck elastomer.

4, rear cover is connect by bolt with thrust holder structure, easy to disassemble.

Detailed description of the invention

It is illustrated below in conjunction with attached drawing with embodiment

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Referring to attached drawing 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 connect 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 protrudes into mesoporous, is equipped with elastomer 4 between kingbolt and thrust bearing, the kingbolt with Clearance fit between thrust holder structure, kingbolt can be moved forward and backward under push action cylinder effect in regime of elastic deformation, thrust Holder structure front end is equipped with thrust pad 1, is equipped with the through-hole 10 being connected to mesoporous in 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, it covers after described equipped with oil cylinder via hole, so that bulb is connect with extraneous oil cylinder, the rear cover passes through It is bolted on thrust holder structure.

This support boots working 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.

The protection scope of the utility model is not limited to the above embodiments, it is clear that those skilled in the art can be right The utility model carries out various changes and deformation without departing from the scope of the utility model and spirit.If these changes and deformation Belong in the range of the claims of the present invention and its equivalent technology, then the intention of the utility model also include these change and Including deformation.
