121 height is reduced, and is adapted to the mode of benching tunnelling method construction, reduces the next support body dismounting transport of engineering method transfer zone tired
Difficulty, saves the time and improves operating efficiency；And connector 123 is installed on upper frame 120 and lower frame 110, construction when
Wait, can muck discharging process completion before by bow member be arranged on excavate stand 100 on, so as to by the past after slagging tap
The sequential analysis for completing bow member installation is changed into parallel operations, saves the time of bow member on-site consolidation, improves operating efficiency；And under
Extensible member 111 on support body 110 can stretch, and be adapted to the construction demand in the tunnel of different in width, be applicable with very strong
Property；The convenient movement for excavating stand 100 of running gear 160, and positioner 115 can assist to excavate the positioning of stand 100；On
Erecting by overhang 170 is installed, convenient be arranged on bow member is excavated on stand 100 on support body 120 and lower frame 110；And cantilever shalving
140 can store, when work, regulation to the first operating position, when work is not needed, regulation to the second working position
Put, save space, and when the first operating position, the 3rd support surface 190 on upper frame 120 or lower frame 110 can
To play a supporting role to support member 142, the stress of a part of rod member 141 is shared, with very high security；And on
Grid foot plank 1211 is provided with crossbeam 113 on support body 120 and lower frame 110, the attachment of concrete can be effectively reduced,
The workload of cleaning is reduced, and pushing meanss 114 are installed on lower frame 110, when can be with convenient construction, bow member be pushed away
The position of work is entered, also, due to having fixing device 201 in adjusting means 200, first can be arranged fixing device 201
On column 112 on upper frame 120, then the wedge 2012 in fixing device 201 is advanced to using propulsion plant 202
Inside wedge shape space 20112, now, fixing device 201 keeps the first working condition, and fixing device 201 and upper frame 120 are fixed
Connection, continues with propulsion plant 202 and is promoted, and upper frame 120 can be directed away to the direction motion of lower frame 110,
When being advanced to a certain degree, it can stop promoting, the position of upper frame 120 and lower frame 110 is utilized into other columns
The working condition of fixing device 201 first on 112 is kept being relatively fixed, and fixing device 201 then is kept into the second working condition,
Then fixing device 201 is set in apart from the closer proximity of propulsion plant 202, fixing device 201 is then kept into the first work
Make state, then just can continue to promote using propulsion plant 202.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
