Abstract
The utility model discloses the device that shield tail during a kind of reception for shield separates with shaping section of jurisdiction, including I-steel and the supporting steel plate for being welded on I-steel axial direction both ends, the roof center opening position of I-steel is welded with section of jurisdiction hoisting head, offers the bolt hole for wearing arch screw bolt on the supporting steel plate described in one piece wherein.The utility model advantage securely and reliably, substantially increases efficiency of construction, cost of labor is greatly lowered in the do mechanization operation realized shield tail be molded in the separation process of section of jurisdiction.I-steel is 250H shaped steel, and supporting steel plate uses 20mm steel plates, and section of jurisdiction hoisting head uses old section of jurisdiction hoisting head, therefore can process at the construction field (site), low manufacture cost.
Description
Technical field
It the utility model is related to shield and receive construction, be especially for shield tail when shield receives and separated with shaping section of jurisdiction
Device.
Background technology
In Construction of Urban Rail Traffic, shield method tunnel construction, because its is safe, speed of application is fast, have become
The main construction method of each urban track traffic constructing tunnel.Shield tail separates with shaping section of jurisdiction when shield receives, and being exactly will shaping
Section of jurisdiction（Reception ring）Deviate from the 3rd tail sealing brush of shield tail, so that the shield machine after separating carries out tearing machine operation open.Conventional shield
Shield machine is separated with shaping section of jurisdiction using the method in the assembled two pieces of interim sections of jurisdiction in shield tail bottom when structure receives, still,
After being separated due to shield machine with shaping section of jurisdiction, duct piece assembling machine vertically moves oil cylinder range and does not reach two pieces of interim section of jurisdiction positions
Put, therefore two pieces of interim sections of jurisdiction can not be removed with duct piece assembling machine, can only rely on tearing open for artificial two pieces of interim sections of jurisdiction of progress
Remove and transport outward, workload is big, and process is cumbersome, and the human and material resources of input are more, and operating efficiency is low；Simultaneously as working space is narrow
Small, there is hidden danger in the dismounting for manually carrying out two pieces of interim sections of jurisdiction.
The content of the invention
The utility model purpose be to provide it is a kind of it is safe and reliable, artificial input amount is few, efficiency of construction is high is used for shield
The device that shield tail separates with shaping section of jurisdiction during reception.
To achieve the above object, the utility model takes following technical proposals：
The device that shield tail separates with shaping section of jurisdiction during the reception described in the utility model for shield, including I-steel and welding
Supporting steel plate at I-steel axial direction both ends, the roof center opening position of I-steel is welded with section of jurisdiction hoisting head, at it
In bolt hole for wearing arch screw bolt is offered on supporting steel plate described in one piece.
The utility model advantage in realize shield tail be molded section of jurisdiction separation process in do mechanization operation, securely and reliably,
Efficiency of construction is substantially increased, cost of labor is greatly lowered.I-steel is 250H shaped steel, and supporting steel plate uses 20mm thickness steel
Plate, section of jurisdiction hoisting head uses old section of jurisdiction hoisting head, therefore can process at the construction field (site), low manufacture cost.

Embodiment
Embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings, the present embodiment is with the utility model technology
Implemented under premised on scheme, give detailed embodiment and specific operating process, but protection of the present utility model
Scope is not limited to following embodiments.
As Figure 1-4, the device that shield tail separates with shaping section of jurisdiction during the reception described in the utility model for shield, including
Support arm, the support arm is by I-steel 1 and the supporting steel plate 2,3 for being welded on the 1 axial both ends of I-steel, and welding
Formed in the section of jurisdiction hoisting head 4 of the roof center opening position of I-steel 1, offer use on the supporting steel plate 2 described in one piece wherein
In the bolt hole 6 for wearing arch screw bolt 5.
The utility model is used for shield tail when shield receives and is summarized as follows with the job step that shaping section of jurisdiction separates：
The first step, as shown in figure 5, shield machine driving after the completion of, open assembled pattern：The underface of shield body 7 is pushed away first
Enter oil cylinder 8 to withdraw, then first support arm is put in place by duct piece assembling machine, supported this with arch screw bolt 5
The supporting steel plate 2 that the bolt hole 6 is offered on arm is connected with reception ring section of jurisdiction 9, by the underface propelling cylinder of the shield body 7
8 stretch out the supporting steel plate 3 for holding out against the support arm the other end, the arch screw bolt 5 are fastened, state now is as shown in Figure 6；
Second step, the propelling cylinder of the underface of the shield body 45 ° and underface 45 ° of opening positions to the right to the left is received successively
Return, using the same method of second step, second support arm and the 3rd support arm are installed, spelled the section of jurisdiction after installation
Installation resets；
Propulsion operation is carried out after 3rd step, three support arm installations；Propulsion uses shield machine assembly pattern, grasps
Make personnel by shield body propelling cylinder guidance panel, operate underface propelling cylinder 8 and 45 ° to the left of the underface of the shield body 7
Propelling cylinder and underface 45 ° of propelling cylinders to the right synchronize propulsion, and remaining propelling cylinder of shield body 7, which is in, withdraws shape
State, forbid to open；
4th step, when the shield body 7 be advanced into the 3rd tail sealing brush depart from portal water-tight device when, in time using chain
Bar crane tenses portal water-tight device, avoids portal from gushing mud, the generation of flowing water phenomenon；
5th step, as shown in fig. 7, when the shield body 7 be advanced into the 3rd tail sealing brush 10 completely disengage it is described
During reception ring section of jurisdiction 9, shield body 7 is advancing to the position, and stops promoting, mask work is completed；
6th step, it is described be advancing to the position after, first with the duct piece assembling machine by the branch of underface first of the shield body 7
Brace is firmly grasped, and then removes the arch screw bolt 5 on first support arm, the underface propelling cylinder 8 of shield body 7 is withdrawn, by first
Individual support arm is removed to be placed into and fed on piece machine, using same method, removes second support arm and the 3rd branch successively
Brace, which is placed into, is fed on piece machine, and three support arms are hung on Gilled tube transporting carriage finally by segment crane and are transported to ground storage.
