Description
Technical field
The utility model is related to shield machine hinge apparatus technical field, and in particular to a kind of new shield machine is hinged sealing
Part.
Background technology
It is to increase the device of the flexibility of shield machine that shield machine, which is hinged,.It makes shield function flexibly turn in the soil body
It is curved more to adapt to design curve.Increase is hinged the contact necessarily increased with the soil body, causes water burst, gushes the phenomenon of sand, causes ground
Face is settled.So the Sealing Technology being hinged is by for key.
Current shield machine be hinged generally the front and rear shield shell of hinged place on shield machine is realized using single seal it is close
Envelope, due to shield, to be hinged seal its hardness higher, after the connection sealing of front and rear shield shell, largely effects on the bending of shield machine, urgently
It is to be modified.
Utility model content
The purpose of this utility model is that defect and deficiency for prior art, there is provided one kind is simple in construction, is designed and closed
Reason, new shield machine easy to use are hinged seal, and detachable connection, and its are used between shield shell before and after shield machine
Hardness is relatively low, and can realize does not influence shield machine also bending while sealing is advanced, and practicality is stronger.
To achieve the above object, the technical solution adopted in the utility model is：It includes seal, fixing bolt；It is described
The rear and front end of seal be connected respectively by fixing bolt with shell after shield machine fore shell, shield machine；Described sealing
Part is silicone elastomer seal；Magnetic gasket is equipped with the inside of its two ends；The outer face of described magnetic gasket is embedded
In the caulking groove of seal two ends madial wall.
Further, the inside middle portion of described seal, which is provided with cell body, cell body, is embedded with spring, the two ends point of spring
Two sides not with cell body are connected.
Further, described fixing bolt is embedded in seal, and its outer face is flushed with the outer wall of seal.
Further, the inner face of described magnetic gasket is embedded the groove on the outside of shell after shield machine fore shell and shield machine
It is interior.
Further, the lateral wall of described seal is provided with anticorrosion antiwear layer.
After said structure, the utility model has the beneficial effect that：A kind of new shield machine described in the utility model
Seal is hinged, detachable connection is used between shield shell before and after shield machine, and its hardness is relatively low, can realize sealedly same
When do not influence also the bending of shield machine to advance, practicality is stronger, and the utility model has simple in construction, and it is reasonable to set, and is fabricated to
This low advantage.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the scheme of installation of the utility model and shield machine.
Fig. 2 is the structural representation of seal in the utility model.
Fig. 3 is the side view of seal in the utility model.
Description of reference numerals：
Shell 4, magnetic gasket 5, caulking groove 6, fixing threaded hole after seal 1, fixing bolt 2, shield machine fore shell 3, shield machine
7th, cell body 8, spring 9, anticorrosion antiwear layer 10.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Referring to as shown in Figure 1-Figure 3, the technical scheme that present embodiment is used is：It includes seal 1, fixed spiral shell
Bolt 2；The rear and front end of described seal 1 is equipped with fixing threaded hole 7, and the rear and front end of described seal 1 is respectively by solid
Determine bolt 2 to be connected with shell 4 after shield machine fore shell 3, shield machine；Described seal 1 is silicone elastomer seal；Its two ends
Inner side is equipped with magnetic gasket 5；The outer face of described magnetic gasket 5 is embedded the caulking groove 6 in the two ends madial wall of seal 1
It is interior, and be connected by the inwall of glue and caulking groove 6.
Further, the inside middle portion of described seal 1 is provided with cell body 8, cell body and is embedded with spring 9, the two of spring 9
Two sides by glue respectively with cell body 8 are held to be connected.
Further, described fixing bolt 2 is embedded in seal 1, and its outer face is flushed with the outer wall of seal 1.
Further, the inner face of described magnetic gasket 5 is embedded the outside of shell 4 after shield machine fore shell 3 and shield machine
Groove in, and be connected by the inwall of glue and groove.
Further, the lateral wall of described seal 1 is by glue provided with anticorrosion antiwear layer 10, and anticorrosion antiwear layer 10 is adopted
It is made of scale copper, scale copper has certain expansion and contraction, ensure that certain flexibility and degree of drawing.
The operation principle of present embodiment：Original steel sealing part is replaced using silicone elastomer seal, greatly
Ensure the bending of shield machine in degree, wherein magnetic gasket 5 can effectively ensure that the close of the two ends of seal 1 and shield machine housing
The setting of sealing property, wherein spring 9, can aid in the reduction after the two-part buckling of shells of shield machine.
After said structure, present embodiment has the beneficial effect that：It is a kind of new described in present embodiment
Shield machine be hinged seal, detachable connection is used between shield shell before and after shield machine, and its hardness is relatively low, can realize
The bending of shield machine is not influenceed also to advance while sealing, practicality is stronger, the utility model has simple in construction, setting conjunction
The advantages of reason, low manufacture cost.
It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover among right of the present utility model.
