Description
Technical field
The utility model relates to a kind of full section template chassis, and definite saying so is used to excavate end face carries out construction of concrete lining for circular or horseshoe-shaped tunnel large-scale template equipment.
Background technology
At present at the wholecircle needle beam chassis that uses mainly by template, the needle beam frame, needle beam, preceding base, rear base, the connection template is very heavy in the needle beam frame, oil cylinder, parts such as haulage gear are formed, template links to each other with the needle beam frame by bolt, the needle beam frame can drive template and slide on needle beam, needle beam is before jacking cylinder is connected in, on the rear base, before, rear base be based on respectively tunnel served as a contrast cut basal plane and the excavation basal plane on, hoist engine is established in the needle beam rear end, preceding, when rear base is the strong point, can draw the needle beam frame slides before and after needle beam, when being the strong point, can drawing needle beam and before and after the needle beam frame, slide with the template.Its template by: be fixed in bed die on the needle beam frame, form with hinged left side mould and the right mould of bed die and arranged on left and right sides respectively by pin, left side mould and the right mould can rotate around bearing pin.Template is supported on the needle beam frame by very heavy and oil cylinder during fluid concrete.During the demoulding: earlier by shrinking second demoulding oil jar, left side mould is broken away from lining, again by shrinking first demoulding oil jar, the right mould is taken off the lining face, by rising long jacking cylinder bed die is taken off the lining face at last, whole like this template limit broken away from the concrete lining face, just moving die plate vertically.This type chassis shortcoming is: one, demoulding amount (demoulding rear pattern plate and lining gap) is less, and when handling this trolley running, template and concrete are easy to generate to wipe and hang.Two, the weight of this type chassis is heavier, uneconomical.Three, when the tunnel of small size section uses this type chassis, this type chassis takes up room greatly, is unfavorable for that the workman constructs.
Summary of the invention
The utility model is intended to overcome the defective that above-mentioned existing wholecircle needle beam chassis exists, provide a kind of template and concrete to be not easy to produce to wipe hang, template weight gently, better economy, the full section template chassis being convenient to construct.
The technical solution of the utility model is as follows:
The full section template chassis of slidnig track type comprises template, longeron, fore-stock, after-poppet, demoulding oil jar, it is characterized in that: fore-stock is installed on the slidnig track type elder generation nose girder, and the crawler shoe on the first nose girder rotates the drive fore-stock forward or backwards and formerly relatively moves on the nose girder.
Described fore-stock comprises first fore-stock and second fore-stock, and second fore-stock and the after-poppet bottom of rear end are provided with jacking cylinder, extend during formwork, shrink during the demoulding; After the demoulding, roadbed that the roller of after-poppet through the bottom laying or the walking of the guide rail on the roadbed, fore-stock is driven by the crawler shoe device and formerly walks on the nose girder through roller, and the walking of front and back support realizes the transfer of bricklaying surface.
Described template is made of backform, left and right sides Bian Mo, bed die; backform is connected with longeron, and left and right limit mould is connected with longeron through first demoulding oil jar, and Bian Mo and backform both sides flexibly connect; left side mould or the right mould and bed die flexibly connect, and bed die is connected with left side mould or the right mould via second demoulding oil jar.
Advantage of the present utility model is:
One, demoulding amount (demoulding rear pattern plate and lining gap) is bigger, and when handling this type trolley running, template and concrete are not easy to produce to wipe and hang.
Two, light, the better economy of the template weight of this type chassis.
Three, when the tunnel of small size section used this type chassis, the constructor had bigger working space.

The specific embodiment
The utility model is compared with existing wholecircle needle beam chassis, and it is simple in structure and walking manner is different.The utility model is mainly by (seeing Fig. 1,2,3,4): after-poppet 1, longeron 2, second fore-stock 3, first fore-stock 4, drive unit 5, first nose girder 6, template 7,8,9,10,, parts such as oil cylinder 11,12,13 form.Elder generation's nose girder 6 connects with first fore-stock and second fore-stock by roller and crawler shoe device 14 on first fore-stock 4 and second fore-stock 3, and first nose girder 6 relative first fore-stocks and second fore-stock can only longitudinal sliding motions.Forward and backward support 1,3,4 is fixedlyed connected with longeron 2, and forward and backward support 1,3,4 drives templates along lining cutting basal plane or the guide rail and the crawler shoe longitudinal sliding motion of having laid on the lining cutting basal plane by longeron 2.Elder generation's nose girder 6 is based on the tunnel excavation basal plane.First fore-stock 4 is provided with drive unit 5, when being the strong point with first nose girder 6, can draw forward and backward support 1,3,4 along lining cutting basal plane or the guide rail and 6 longitudinal sliding motions of first nose girder of having laid on the lining cutting basal plane, when former support 3,4 is the strong point, can draws first nose girder 6 and slide along fore-stock 3,4.After-poppet 1 is provided with jacking cylinder 12 and roller, can be along lining cutting basal plane or the guide rail longitudinal sliding motion of having laid on the lining cutting basal plane, and jacking cylinder 12 1 ends are fixedlyed connected with second fore-stock with after-poppet, and the other end is supported on the lining cutting basal plane and excavation basal plane.
The composition (see figure 4) of template: be fixed in backform 7 on the longeron, be positioned at the left and right limit mould 8,9 of longeron 2 both sides, left and right limit mould 8,9 by pin with respectively hinged with backform 7 and arranged on left and right sides, link together with longeron 2 through first demoulding oil jar 11.Left and right limit mould can rotate around bearing pin, and bed die 10 1 sides and the right mould 9 or left side mould 8 one sides are hinged by bearing pin, and can rotate around bearing pin.Opposite side is fixedlyed connected with left side mould 8 or the right mould 9 one sides by bolt or spacer pin, and is connected with the right mould 9 or left side mould 8 via second demoulding oil jar 13.During fluid concrete, bed die 10 is fixedlyed connected by bolt or spacer pin with the right mould 9 or left side mould 8, the rigidity opposing of master plate external applied load own.
During the demoulding, unclamp the bolt or the spacer pin of bed die 10 and left side mould 8 or the right mould 9 earlier, shrink second demoulding oil jar 13, bed die 10 is broken away from lining, shrink first demoulding oil jar 11 again with a left side, the right mould 8,9 breaks away from lining and by shrinking jacking cylinder 12 backform 8 is broken away from lining then, on the guide rail that makes roller on the after-poppet 1 be supported in the lining cutting basal plane simultaneously or laid on the lining cutting basal plane, crawler shoe 6 is supported in the excavation basal plane, this moment, jacking cylinder 12 left lining cutting basal plane and excavation basal plane, handled drive unit 5 straight skidding templates to next lining cutting position.
During lining cutting, rise long jacking cylinder 12, backform 7 is risen to the lining cutting position, crawler shoe also leaves the excavation basal plane simultaneously, handle vertically slippage crawler shoe 6 forward of drive unit 5, leave the lining cutting position, rise long second demoulding oil jar 13 earlier, the back rises long first demoulding oil jar 11 and makes bed die 10, right, the left side 9,8 moulds install the bolt or the spacer pin of bed die 10 and left side mould 8 or the right mould 9 to the lining cutting position, just can carry out lining cutting.
