After being straightened completely, middle layer inner platform 310 will be driven to move upwards, and then drives to be located in middle layer inner platform 310 and lowest level and put down
Foldable assembly 311 between platform 310 is straightened, final that lowest level inner platform 310 is driven to move upwards, when internally positioned platform body
After 30 jackings in place, top layer's inner platform 310, middle layer inner platform 310, lowest level inner platform 310 also will respectively in place.
As shown in Fig. 1 and 18, under tunneling boring operating condition, three platform bodies 30 in platform assembly 3 are fully deployed in place, can
Have three layers of inner platform 310, three layers of side platform 3211, one layer of internally positioned 30 top of platform body can fully meet different height
Degree under operation when, the support demand of operator and equipment.
Under half section operating condition, maximum height has certain drop compared to tunneling boring operating condition, is now placed in internal platform
Body 30 is in jacking state, is located in the middle platform body 30 and is in rounding state, correspondingly, is only unfolded and internally positioned platform
The side platform 3211 that body 30 is connected and the side platform 3211 being connected with the platform body 30 for being located at outside.Under such operating condition, tool
Standby two layers of inner platform 310, two layers of side platform 3211, one layer of internally positioned 30 top of platform body can be fully met in half section,
When operation under different height, the support demand of operator and equipment.
As shown in figure 18, when tunnel carries out arching operation, arch piece is divided into 5, is divided at left and right sides of tunnel cross-section altogether
There is the top arch piece 8 at the top of two pairs of symmetrical arch pieces and tunnel cross-section.Very narrow inside tunnel, current technology mode is
Section construction step by step, cannot a handgrip all arches are installed, frame is too low for efficiency.The characteristics of according to the operating condition, this reality
It applies mode arching vehicle and is disposed with three layers of handgrip, top handgrip 411 is responsible for the installation of top arch piece 8, internally positioned 30 He of platform body
It is equipped with side handgrip mechanism 5 positioned at external platform body 30, i.e., the top handgrip assembly 503 in internally positioned platform body 30 is negative
The installation of duty upside arch piece, is responsible for the installation of downside feed positioned at the lower gripper assembly 503 of external platform body 30, pushes up handgrip
411 and handgrip assembly 503 can simultaneously operation, thus a rack arch vehicle can disposably complete three pieces arch piece operation, improve frame
Encircle operating efficiency.
When arching operation, top arch piece 8 is lifted on the handgrip 411 of top by loop wheel machine 40, then passes through telescopic seat 410 again
It is flexible top arch piece 8 top is reached into tunnel top proper height, in place after, can be by adjusting top handgrip 411 in telescopic seat 410
On relative position, realize top arch piece 8 tunnel longitudinal direction construction location adjustment, adapt to tunnel top out-of-flatness operating condition want
It asks.It, will by operator station on the side platform 3211 being connected with internally positioned platform body 30 while top layer construction
The side handgrip mechanism 5 at internally positioned 30 top of platform body is collapsed around bearing base body rotary expansion, then by fixed pin shaft
It removes, unclamps support component 51 downward relative to level-one rotating arm 501, support wheel 511 is supported on side platform 3211, rear logical
Cross adjustment level-one rotating arm 501, handgrip assembly 503 is moved to arching vehicle rear, then passes through and hang by the angle of second level rotating arm 502
The arch piece for being located at side is lifted on top handgrip assembly 503 by machine 40, then is rotated by adjusting level-one rotating arm 501, second level
Arch piece on top handgrip assembly 503 is moved to suitable construction location by the angle of arm 502, and encircles piece with the top fixed
8 are hinged, and the side handgrip mechanism 5 of lower section opens up receipts and application method with the side handgrip mechanism 5 of top, wherein the side handgrip of lower section
The support wheel 511 that mechanism 5 includes is supported on scaling platform 3222.When arching vehicle collapses, the side handgrip mechanism 5 of top collapse in
The side handgrip mechanism 5 at the top of internally positioned platform body 30, lower section is collapsed in the side for being located at external platform body 30, is reached
Vehicle integrally collapses, convenient transportation.
Present embodiment has the advantages that 1, present embodiment arching car exhibition can provide multilayer operation platform after opening, and has
The multilayer height requirement of artificial construction in effect covering tunnel etc..2, present embodiment arching car exhibition big, energy of opening rear platform covering surface
Meet more people's construction requirements, equipment placement space and operating space of other auxiliary construction operations such as drilling etc. can be provided, improves
The construction operations efficiency such as tunnel.3, present embodiment arching vehicle can disposably complete the arching operation of multiple arch piece, improve arching
Efficiency.4, present embodiment arching bassinet structure is reliable and stable, and arching is high-efficient.5, when the not operation of present embodiment arching vehicle,
It folds and collapses, occupy little space, convenient transportation and storage.6, it is multi-faceted to be able to achieve space for present embodiment side handgrip component 50
It adjusts, is able to satisfy the crawl operation of different arch pieces, adapts to the complex situations of tunnel cross-section, improve arching operating efficiency, do not make
Used time folds relative to platform assembly 3 and collapses, and occupies little space, convenient transportation and storage.
