Abstract
A kind of auxiliary propulsion plant for shield-tunneling construction comprising auxiliary jack, the auxiliary jack is set on the inside of shield machine shield tail shell by jack mounting groove, among the original-pack propelling cylinder of shield machine, for promoting shield machine thrust.Auxiliary propulsion plant processing and fabricating provided by the utility model for shield-tunneling construction is simple, and installation operation is convenient, there is stronger applicability；Auxiliary propulsion plant has the characteristics that plug and play, encountered during shield-tunneling construction shield machine it is stuck when, or utility model device is installed when encountering barrier, so as to effectively solve the stuck problem of shield machine.
Description
Technical field
The utility model is related to Subway Tunnel shield-tunneling construction auxiliary device fields, more specifically to a kind of to be applied to shield
The auxiliary propulsion plant of structure construction.
Background technology
Currently, the tunnels such as more and more subways, high ferro, highway, municipal administration and water power are all constructed using shield machine, shield
The passed through stratum of structure construction becomes increasingly complex, and various barriers or different ground textures are likely encountered in crossing process
It makes.When shield machine encounters hard barrier, limited normal thrust may cannot be satisfied construction demand, easily lead to shield machine
It is stuck.
Utility model content
In view of the shortcomings of the prior art, the utility model provides one kind for shield-tunneling construction and can effectively solve shield machine card
Dead auxiliary propulsion plant.
The technical scheme in the invention for solving the above technical problem is：A kind of auxiliary propulsion for shield-tunneling construction
Device comprising auxiliary jack, the auxiliary jack are set to shield machine shield tail shell inside, shield by jack mounting groove
Among the original-pack propelling cylinder of structure machine, for promoting shield machine thrust.
Further, further include cushion block, the cushion block is set between auxiliary jack top and shield machine segment, is used for
The advance distance of adjustment auxiliary jack.
Further, the cushion block is lightweight, rigid material, and cushion block is internally provided with gusset.
Further, it is provided with connecting hole on the cushion block, for connecting installation between cushion block.
Further, the mounting groove is set on the inside of shield machine shield tail shell, among the original-pack propelling cylinder of shield machine.
Compared with prior art, what the utility model had has the beneficial effect that：It is provided by the utility model to be applied for shield
The auxiliary propulsion plant processing and fabricating of work is simple, and installation operation is convenient, there is stronger applicability；Auxiliary propulsion plant, which has, to be filled
The characteristics of using, encountered during shield-tunneling construction shield machine it is stuck when, or the utility model is installed when encountering barrier
Device, so as to effectively solve the stuck problem of shield machine.

Fig. 2 is the utility model shield machine another kind structural schematic diagram；
Fig. 3 is partial enlarged view at A in Fig. 2；
Fig. 4 is that jack schematic view of the mounting position is assisted in the utility model shield machine side structure schematic view；
Fig. 5 is partial enlarged view at B in Fig. 4.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-5, a kind of auxiliary propulsion plant for shield-tunneling construction comprising auxiliary jack 6, the auxiliary
Jack 6 is set to by jack mounting groove 1 among the original-pack propelling cylinder of the inside of shield machine shield tail shell 4, shield machine 2, is used for
Promote shield machine thrust.
Further, since auxiliary 6 general stroke of jack only has 40cm, and original-pack 2 stroke one of propelling cylinder of shield machine
As up to 2m or more, therefore the auxiliary propulsion plant of the utility model needs to customize cushion block 7, and it is very heavy that the cushion block 7 is set to auxiliary
It pushes up between top and shield machine segment 5, the advance distance for adjusting auxiliary jack 6.
Further, the cushion block 7 using rigidity larger, lighter weight material, be highly 15cm, inside set gusset,
And connecting hole is set, it is installed convenient for connection between each other.
Further, the mounting groove 1 is set in the original-pack propelling cylinder of the inside of shield machine shield tail shell 4, shield machine 2
Between, the position close to shield tail front end, the original-pack propelling cylinder of shield machine 2 is set to 3 inside of middle shield shell.It assists jack 6 to be equipped with to connect
Plugboard is easily installed in mounting groove 1.
When shield machine only lean on normal thrust can not advance when and shield-tunneling construction during encounter shield machine it is stuck when, you can
It installs the present apparatus additional, to effectively promote thrust, avoids shield machine stuck.Specifically, auxiliary jack 6 is pacified by mounting groove 1
Dress is fixed, and the tail portion of auxiliary jack 6 is withstood on shield tail partition board, and piston effect will assist jack in cushion block 7, by cushion block 7
Thrust be applied on shield machine and increase augmented thrust for shield machine, and original-pack jack thrust collective effect promotes shield machine
Thrust, to avoid shield machine stuck.The usage quantity of cushion block 7 can be determined according to original-pack 2 advance distance of propelling cylinder of shield machine.
When shield machine is working properly, i.e., the auxiliary propulsion plant is removed, in order to operation.
It should be noted that the product form and style of above-described embodiment and schema and non-limiting the utility model, any
The appropriate changes or modifications that person of an ordinary skill in the technical field does it all should be regarded as not departing from the utility model
Patent category.
