Description
The utility model relates to a kind of railway tunnel that is used for, particularly electrified railway tunnels enlarging, construction maintenance unit.
Do not having a power failure, under the situation about not cutting off traffic, transforming railway tunnel, to Development of Railway, improving transport capacity has been a difficult problem of being badly in need of solution.Tunnel reconstruction work is to carry out under the condition that has a power failure, cuts off traffic both at home and abroad at present." railway track top architectural furniture " (Chinese patent: 86204286.0) of railway scientific research institution, Xi'an development, solved the problem of livewire work, make in bright, the hangar tunnel construction of electrified sections and accomplish uninterrupted operation, improve efficiency of construction greatly, reduced the conveyance loss that causes because of power failure.But said apparatus is that the enlarging construction in wired tunnel is inapplicable for electric railway, still need have a power failure, and cuts off traffic, and constructs.
The utility model is according to the deficiency of prior art, a kind of new design scheme has been proposed, design a kind of constructing tunnel protector, purpose provides a kind of constructing tunnel equipment that neither cuts off traffic and can guarantee construction safety in electrified railway tunnels, can be used for removing or change tunnel lining is promptly arranged, enlarge tunnel cross-section etc., can be used as the template of augmenting lining cutting again.Be to transform the railway existing line, increase and build multiple line new construction equipment is provided.
Technical essential of the present utility model is that total is closed, bolted pin-connected panel steel work.The arch ring of this constructing tunnel protector comprises three sections arch joints, be provided with the flank door, spiral is set on the truss upright-column to be supported and connector, rotate the leading screw that spiral supports, leading screw is tightly supportted in tunnel lining, and the leading screw that rotates connector can make and hang over the band that is embedded in the tunnel lining and collude chain link tension on the anchor pole.Longeron is provided with the transverse splicing bar under the trusses, by cross bar with hound is hinged forms.Cross bar is passing between the sleeper below the rail, near ballast aggregate.Hound is connected with following longeron by bolt, and the transverse splicing bar can be with horizontal load by hound, and cross bar passes to ballast aggregate, strengthens the stability increasing supporting capacity of whole device by the use of connector, support helix and transverse splicing bar.For preventing that quarrel stone falls into the driving gauge in the construction, arch ring is provided with steel plate, and truss upright-column is provided with band frame steel plate, also is provided with steel plate on the flank door, makes the sealing of this device, to realize safe construction.
Accompanying drawing 1 is a constructing tunnel protector elevation
Accompanying drawing 2 is a constructing tunnel protector lateral view
In accompanying drawing 1,1 is truss, and 2 for encircleing joint down, and 3 is the intermediate arches joint, and 4 is all-insulated plate, and 5 is fixed coupling unit, and 6 for band colludes anchor pole, and 7 is tunnel lining, and 8 is support helix, and 9 is cross bar, and 10 is hound, and 11 is travelling wheel, and 12 is interim rail.
In accompanying drawing 2,13 is truss upright-column, and 14 is the control sprocket wheel of flank door, 15 is driving chain, and 16 for the flank door opens and closes spiral, and 17 is the flank door, 18 is the framework of flank door, 19 is flank door bolt axle, and 20 is the vertical connecting rod of arch ring, and 21 is arch ring top steel plate, 22 is longeron on the truss, 23 is truss band frame steel plate, and 24 is longeron under the truss, and 25 is jack.
Now in conjunction with the accompanying drawings the utility model is elaborated.
The utility model total is closed, and the pin-connected panel steel work that spiral connects is by truss 1, arch joint 2,3, all-insulated plate 4, transverse splicing bar 9,10, running part 11,12, support helix 8, flank gate control sprocket wheel 14, fixed connection bar 5, driving chain 15, jack 25 grades are partly formed.Specifically be performed such: the top of the utility model both sides truss 1 is fixed with arch joint 2,3 respectively, is become a whole arch ring between arch joint 2 saves 3 with arch by bolted on connection.Change the width that intermediate arches joint 3 can change close whole device; Change column 13 height on the both sides truss 1, can change whole height of devices, to adapt to the different headroom in tunnel.Column 13 is provided with longeron 22, following longeron 24.Last longeron 22 connects with bolt and column 13 respectively mutually with following longeron 24.The arch ring 2,3 that truss 1 top is provided with connects with last longeron 22 mutually by bolt respectively.For stability and the security reliability that intensifier uses, truss upright-column 13 is provided with screw, leading screw and connects the fixed coupling unit 5 that chain link is formed, support helix 8.The screw of fixed connection spare 5 is welded on the column 13, is fixing joining link before the leading screw.Joining link hangs over to be embedded in to be with in the tunnel lining 7 and colludes on the anchor pole 6, can strain joining link or unclamp joining link by rotational lead screw.Support helix 8 is made up of screw, leading screw.Screw is welded on the column 13, and rotational lead screw tightly supports in tunnel lining 7 the leading screw supporting surface.It is by cross bar 9 and hound 10 hinged forming that the following longeron 24 of truss 1 is provided with the transverse splicing bar, and cross bar 9 passes between the sleeper of track below, is close to ballast aggregate.Hound 10 is connected with following longeron 24 by bolt, the transverse splicing bar can pass to ballast aggregate by hound 10, cross bar 9 with horizontal load, by the use of fixed connection spare 5, support helix 8 and transverse splicing bar 9,10, strengthen the stability of whole device, strengthen supporting capacity.Following arch joint 2 is provided with flank door 17, and truss upright-column 13 is provided with flank gate control sprocket wheel 14, and longeron 22 is provided with the flank door and opens and closes spiral 16 on the truss.Rotate flank gate control sprocket wheel 14, pass to the flank door by driving chain 15 and open and close spiral 16, drive flank door 17 opens around bearing pin 19 rotations or regains.Arch and tunnel top that flank door 17 opens this device of back fit tightly, be unlikely very big shock loading, before this device moves, must fall, and the withdrawal of flank door 17, make this device fall back arch ring 2,3 and tunnel vault everywhere distance equate, be convenient to mobile this device and the overhead contact built-in spare of can preventing and collide.For preventing that quarrel stone falls into the driving gauge in the construction, at arch ring 2,3, steel plate is housed respectively on the flank door 17, on truss upright-column 13, also be provided with band frame steel plate, make this device for closed.
The utility model compared with the prior art can be in the feelings that do not have a power failure, do not cut off traffic Under the condition, electrified railway tunnels is extended construction, for example remove or change tunnel-liner, enlarge tunnel cross-section etc. Be to transform Existing Railway Line, increase and build multiple line new construction equipment is provided. Simultaneously, this device also can be used for the enlarging construction in the non-electrified railway tunnel, safety, reliable. The utility model resistance to overturning is good, has stronger bearing capacity, and the ballast in can effectively preventing from constructing enters the driving gauge, the traffic safety in guaranteeing to construct.
