Description
Technical field
The utility model relates to a kind of chassis, relates in particular to a kind of working jumbo for tunnel lining.
Background technology
At present, raising along with the construction quality standard, tunnel lining all adopts formwork jumbo to carry out concrete casting and constructing, in construction, behind tunnel (culvert) excavation, carry out first lining cutting, clear up tunnel bottom dregs (picking up the end) then by concrete and steel mesh sheet etc., use the concrete pouring tunnel floor, and according to the short abutment wall in constructing tunnel drawing cast both sides.By the time after base plate and short abutment wall had certain intensity, the rigging chassis carried out lining cutting.Now the jacking cylinder in the formwork jumbo hydraulic system used of society adopts basically is to be placed on the door type frame bottom or on door type frame top, but concrete when equally all adopting the hydraulic lock locking type to bear lining cutting and template pressure, this mode is unscientific.
At first, the structure that links to each other as 4 jacking cylinders of formwork jumbo is a rigidity, but when practice of construction, often be the single-point action, like this, certainly will cause jacking cylinder when knee-action, increased bigger lateral force, aggravated the wearing and tearing of hydraulic seal, if adopt the hydraulic lock sealing again, unload in being easy to cause, and then make just to sink in the template of lining cutting.
Secondly, if below jacking cylinder was placed on, this mode was more defective, this layout not only causes whole formwork jumbo overall structure shakiness, simultaneously, the weight that also makes jacking cylinder not only bear masterplate is also born total weights such as formwork jumbo skeleton and support system simultaneously.
At last, because formwork jumbo is in construction, environment of living in is more mixed and disorderly, and the plug-in hydraulic lock of oil cylinder, careless slightly will being bruised caused thrashing.
The utility model content
The purpose of this utility model is the problem that exists at the jacking cylinder in the formwork jumbo hydraulic system of present society use, a kind of new working jumbo for tunnel lining is provided, this formwork jumbo is by changing the structure of jacking cylinder, thereby make oil cylinder when stressed, by the trapezoidal thread and the nut of cylinder sleeve outer wall, realize mechanical interlocking.
The utility model purpose is achieved through the following technical solutions:
A kind of working jumbo for tunnel lining comprises running gear, door type frame, mechanical support system, limit mould, backform, jacking cylinder, hydraulic system, electrical system, also comprises translation system, bottom girder; Running gear is connected with bottom girder, and door type frame is connected by mechanical support system with the limit mould, the backform system by translation system, rise the top oil cylinder and be connected with door type frame.
Backform is one group, and the limit mould is two groups, and Bian Mo and backform are formed the template system of this chassis; Backform is connected by hinge with the limit mould.
Running gear comprises road wheel, motor, speed changer, and road wheel places on the track.
Jacking cylinder is an one-way cylinder, form by upper flange, lower flange, cylinder sleeve, locking nut, guiding support set, piston, combination sealing, upper flange is fixedly connected on the piston termination, the guiding support set is sleeved on the outside of cylinder sleeve, fixedly connected with upper flange in the upper end of guiding support set, locking nut is sleeved on the cylinder sleeve outside, is positioned at the below of guiding support set; On the oil steel bushing outer wall trapezoidal thread is arranged.
Have oil-in on the lower flange, the oil-in place is provided with the buffering step.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Wherein:
Fig. 1 is a cross-sectional drawing of the present utility model.
Fig. 2 is a skiagraph of the present utility model.
Fig. 3 is a jacking cylinder structural representation of the present utility model.
The specific embodiment
A kind of working jumbo for tunnel lining comprises running gear 1, door type frame 5, mechanical support system 4, limit mould 3, backform 8, rises top oil cylinder 6, hydraulic system, electrical system, also comprises translation system 7, bottom girder 2; Running gear 1 is connected with bottom girder 2, and door type frame 5 is connected by mechanical support system 4 with limit mould 3, backform 8 by translation system 7, rise top oil cylinder 6 and be connected with door type frame 5.
One group of backform 8 and two groups of limit moulds 3 are formed the template system of these chassis, and backform 8 and limit mould 3 are connected by hinge.
Running gear 1 comprises road wheel, motor, speed changer, and road wheel is placed on the track.
Jacking cylinder 6 is made up of upper flange 16, lower flange 10, cylinder sleeve 11, locking nut 12, guiding support set 13, piston 14, combination sealing 15, upper flange 16 is fixedly connected on piston 14 terminations, guiding support set 13 is sleeved on the outside of cylinder sleeve 11, fixedly connected with upper flange 16 in the upper end of guiding support set 13, locking nut 12 is sleeved on cylinder sleeve 11 outsides, is positioned at the below of guiding support set 13; On oil steel bushing 11 outer walls trapezoidal thread is arranged.Jacking cylinder 6 by the trapezoidal thread and the locking nut 12 of cylinder sleeve 11 outer walls, is realized mechanical interlocking when stressed.
Have oil-in on the lower flange 10, the oil-in place is provided with the buffering step, and design can avoid piston to drop to lowermost end like this, and under the condition of loading, oil cylinder can't rise " hydraulic pressure is stuck " phenomenon.
In real work, start movable motor, formwork jumbo is closed movable motor after driving to the lining cutting mileage, transfers rail meter, screws down supporting leg.Starter motor, the operation hydraulic control valve according to the hydraulic operation rules, rises jacking cylinder, to the lining cutting height.And screw locking nut 12 one by one.Again other mechanical support are rotated in place afterwards.
After everything is ready, carry out concrete spouting.
By the time after concrete reaches certain intensity, organize form removal.Tear limit mould mechanical support earlier open, receive limit mould 3 again, remove vertical support then.
At last, starter motor, before unscrewing locking nut 12, fuel feeding in quick fuel feeding, unscrews nut 12 rapidly at first fast, and the reverse operating control valve by the template deadweight, makes jacking cylinder 6 returns.
