Description
Technical field
The invention belongs to underground cavern engineering construction equipment technical field, be specifically related to a kind of concrete lining steel formwork jumboFrame structure.
Background technology
Concrete lining steel formwork jumbo is the indispensable nonstandard product of secondary lining in underground cavern work progress. Due toThe diversity of actual requirement of engineering, makes the size of cave depot section there will be variation, as occur span, height andThe variation that the two has concurrently. Be used at present the telescoping steel form in underground cavern construction, can not adapt to cave depot section and go outSituation about now changing, can only take the method for changing different size telescoping steel form to meet requirement of engineering, like this,In the cave depot construction of many cross dimensions, just need to be equipped with the telescoping steel form of plurality of specifications, not only increased constructionEquipment investment, and installation, assembling, transport, storage and the increase of management chassis cost, reduced engineering constructionBenefit.
Summary of the invention
The shortcoming that the object of the invention is to overcome telescoping steel form bad adaptability in existing cave depot construction, provides a kind ofApplicable to the change of the concrete lining steel formwork jumbo of different cave depot section spans and the high size of wall across uprising device.
For achieving the above object, the technical solution used in the present invention is:
Installation composition is put and uprised to the change of described concrete lining steel formwork jumbo across uprising device by becoming straddle mounting. Become across withUprise function and realize by frame structure, frame structure comprise road wheel, lower longeron, column, door frame crossbeam,Upper longeron, arch crossbeam, telescopic supporting rod.
Become straddle mounting put comprise door frame crossbeam, door frame crossbeam become across oil cylinder, arch crossbeam, arch crossbeam become across oil cylinder,Become across flexible road wheel assembly, become across cross slide way. Door frame crossbeam and arch crossbeam are three joint telescopic structures,Both ends are that box-shaped overcoat, pars intermedia are box inner sleeve, are provided with moving sets between inner-outer sleeve, box overcoat with inOverlap corresponding connecting portion and be uniformly distributed multiple equally spaced connection pin-and-holes. By being arranged on door frame crossbeam and arch horizontal strokeThe push-and-pull of beam intracavity liquid compressing cylinder, make door frame crossbeam and arch crossbeam flexible drive framework to realize to become across.
Uprising device comprises column, uprises oil cylinder. Column is the overlapping telescopic structure of three joints, by inner sleeve, middle coverBe formed by connecting by moving sets with overcoat, relevant position arranges alignment pin and is connected with holding screw. By being arranged onThe two-way function of column intracavity liquid compressing cylinder, makes column up-down drive framework upper motion to realize and uprises.
Further, described hydraulic system is by electrical control.
Further, door frame crossbeam, the change of arch crossbeam are single-piston rod formula double acting push action cylinder across oil cylinder.
Further, to uprise oil cylinder be the telescopic double acting push action cylinder of two-stage stretching to column.
Further, door frame crossbeam, arch crossbeam and pillar construction junction are provided with strength-enhanced structure, described inStrength-enhanced structure be the rectangle frame that an outer use steel plate bar that is enclosed within the inside and outside socket place of body structure is welded.
Further, lower longeron inner chamber doubles as fuel tank.
Further, the change of described concrete lining steel formwork jumbo is across uprising device into singly cutting off structure, according to real workNeed, select two-section and above change across uprising device synchronous working.
The change of concrete lining steel formwork jumbo of the present invention is across the using method that uprises device: a side become across time opposite side motionless;By being fixed on change on the lower longeron hydraulic jack across flexible road wheel assembly, top is lower to be become across flexible road wheel,It is contacted with longitudinal rail, take off the each pin that connects door frame crossbeam and arch crossbeam, becoming across flexible road wheelBelow lay cross slide way, oil cylinder continue action road wheel and longitudinal rail are disengaged, by being arranged onThe door frame crossbeam of door frame crossbeam and arch crossbeam inner chamber becomes across oil cylinder and arch crossbeam and becomes pushing away or drawing and make across oil cylinderDoor frame crossbeam and arch crossbeam drive framework to laterally move to need position, by longitudinal rail by former span positionMove to new span position, by oil cylinder this skidding travelling wheel that lands, it is contacted again with rail, this side becomes and is cross overPosition;
One side become be cross over behind position, opposite side with same method realize become across;
Both sides become across after all putting in place, the more piece box-structure of door frame crossbeam and arch crossbeam are connected to multiple pinsOne, becomes across completing.
Further, the change of described concrete lining steel formwork jumbo, across the using method that uprises device, is removed each column (4)All circular cone alignment pins and the holding screw of upper installation;
By being arranged on the two-way function that uprises oil cylinder of each column inner chamber, make column realize lifting, drive frameThe lifting of frame top realizes and uprising; After needs height and position, each column circular cone alignment pin is installed and is realized altitude location,The all holding screws of each column are installed and are realized fixing between column body structure, uprised.
Adopt the change of the concrete lining steel formwork jumbo that as above technical scheme provides across uprising device compared with prior art,Beneficial effect is:
(1) be provided with become across with uprise device, can certain limit according to the span of cave depot section and height,Laterally overhanging or interior receipts framework and side wall template, raises or reduces framework, bow member and vault template, meets multibreakFace cave depot construction requirement.
(2) change of described concrete lining steel formwork jumbo is across uprising device into singly cutting off structure, can many sections of synchronous uses,Strong adaptability.
(3) overcome in multibreak cave depot concrete lining construction, changed the inconvenience that different telescoping steel forms bring,Effectively save construction cost and improved efficiency of construction.
(4) change of described concrete lining steel formwork jumbo can be realized by the hydraulic system of electrical control across uprising device,Easy to operate, reliable in function.
(5) because following longeron inner chamber doubles as fuel tank, saved material, reduced cost, made overall structureMore succinct.
