Detailed description of the invention
As shown in Figures 1 to 5, for existing defect, the protection main body of the present invention is as follows: exploitation is one
Kind of tunnel overall steel die bush platform building cart binds device, is made up of following structure.
The novel device structure that binds is mainly by panel 1, the cover plate 2 that binds, lift shaft 3, axle bed 4, spacing
Device 5 and the pipe 6 that binds etc. form, and wherein panel 1 is with a big plate of monoblock, use steel plate to make,
Panel is determined a major diameter bind aperture 11, such as, the aperture of binding of 20 cm diameters, envelope
The diameter of apical pore mouth is identical with the internal diameter of the corresponding pipe that binds.Corresponding welds one at the lower surface of panel
Bind pipe 5, and the pipe that binds is pipe, for connecting with concrete conveying pipeline.
A breach 12 determined by the panel of above-mentioned side, aperture 11 of binding, is used for rotating shaft is installed.?
The side contacted with the above-mentioned pipe that binds in breach 12 is provided with a groove 13, is used for discharging slurry.
The cover plate 2 that binds uses chamfer design 22, and the side of the cover plate 2 that binds arranges an ear 21, ear
21 for connecting with lift shaft 3, and connected mode is for being welded to connect, and lift shaft 3 is and the cover plate that binds
Vertical.
Above-mentioned pipe 6 side of binding is provided with some axle beds 4, axle bed about 4 orientation be coaxially disposed and with
After the lift shaft 3 that above-mentioned breach 12 position is the most corresponding, above-mentioned passes breach and axle bed, lower end
Extend out and be provided with the operating side 31 being easy to wrench operated.
The above-mentioned cover plate 2 that binds uses chamfering, band plate ear to design；Lift shaft 3 is fixed with the cover plate 2 that binds
Connect, can lift vertically and rotate；The pipe that binds is fixed as one with the panel 1 of lining trolley, and bind pipe
The indentation, there corresponding with the ear of the cover plate that binds uses bevel design, and concrete binds to manage and is fixed as one with axle bed
Body.
Above-mentioned each parts use process for machining, assemble and complete carry out outer surface grinding process, it is ensured that envelope
The cover plate that binds under apical organ closed mode smooths with slab joint.
Seamless closed-top technology process is as follows:
First, pump concrete binds before placing, the cover plate jacking rotating to outside aperture of binding of binding,
Avoid the orifice position that binds, fit with template, open the mouth of pipe that binds；
Second step, the device concrete that will bind binds to manage and snaps connection with concrete conveying pipeline, and concrete is by pipe
Road is pumped into mould, until filling slurry by mould, and end of binding,
3rd step, binds after end, rotates backward rotation and lifting rotating shaft so that the cover plate that binds turns to bind
At the mouth of pipe, the cover plate that binds falls under the pressure of concrete slurry and closes the mouth of pipe that binds, it is achieved coagulation grave
Top；Binding after cover closure, cover plate smooths with panel outer surface seam, eliminates the faulting of slab ends phenomenon that binds.?
During the above-mentioned cover plate that binds falls, the chamfering on cover plate that binds is arranged so that the cover plate that binds has
Automatic capturing function.
4th step, dismantling concrete conveying pipe, and maintenance,
5th step, maintenance removes, after completing, the device that binds.
By the application of said structure, overall punching block hydraulic lining trolley pumped concrete earth process Novel sealing top skill
The technological process of art: axially jacking lift shaft, rotary seal lamina tecti open hole → connections of binding bind manage and
Concrete delivery pipe → pump concrete → rotation and lifting rotating shaft is until cover plate coincide with aperture of binding and closes envelope
Apical pore → → bound.
The key problem in technology point of the present invention is the perfect knot of covering plate structure, liftable pivot structure and panel of binding
Close, and after closure, the cover plate that binds forms coordinating of a near seamless with panel.Operating process is simple, logical
Cross simple rotation to operate, the structure design that the cover plate that binds axially lifts so that the cover plate that binds can be with steel
Die face plate realizes smooth closely connected, eliminates concrete surface faulting of slab ends phenomenon when binding placing.
As improving further, a limited block can be welded on lift shaft 3 so that bind cover plate
After overlapping with aperture of binding spacing, do not rotating, preventing from rotating excessively, formed and preferably coordinate, form limit
Position device 5.
Lift shaft 3 and the pipe 6 that binds arrange alignment scale 41 simultaneously, when both scales overlap,
Represent that the cover plate upper surface that binds is concordant with panel upper surface, form a complete plane.
Embodiment described above is only to be described the preferred embodiment of the present invention, not to this
Bright scope is defined, on the premise of designing spirit without departing from the present invention, and relevant technical staff in the field
Various deformation and improvement to the present invention, all should expand in protection domain as determined by claims of the present invention.
