The utility model content:
The purpose of the utility model is to overcome the deficiency of prior art and provides a kind of bottom headroom big; Whole demoulding amount is big; Can effectively reduce bubbles volume, improve the bottom Surface Quality of Concrete, and can handle the under shed formula wholecircle needle beam lining trolley with maintenance timely the bottom concrete.
A kind of under shed formula wholecircle needle beam lining trolley comprises beam frame assembly, needle beam assembly, walking wheel frame, stopping means, backform, left side mould, right side mould, left bed die, right bed die and wedge mould with common needle beam chassis; Said beam frame assembly is installed on the said needle beam assembly through said walking wheel frame; Said beam frame assembly is connected with said backform; Flexibly connect between the both sides of said backform and said left side mould and the right side mould; Flexibly connect between said left side mould and left bed die, said right side mould and the right bed die; Said wedge mould one side is movably connected on the said right bed die; Opposite side is installed on the said left bed die, and said backform, left side mould, right side mould, left bed die, right bed die and wedge mould connect to form circular shuttering, is connected through symmetrically arranged side form oil cylinder between said left side mould and right side mould and the said beam frame assembly; Connect through symmetrically arranged bed die oil cylinder between said left bed die and left side mould, right bed die and the right side mould, said left bed die is connected with beam frame assembly bottom through symmetrically arranged jacking cylinder respectively with right bed die.
In the utility model, be equipped with the working window that can be in communication with the outside on said left bed die and the right bed die.
In the utility model, said wedge mould is provided with steam vent.
In the utility model, said beam frame assembly is fixedly connected with right beam by lower transverse beam, Zuo Liang and constitutes, and it is inboard that the Zuo Liang of said beam frame assembly and the upper end of right beam are fixed on said backform, and the lower end is fixedly connected with said lower transverse beam.
In the utility model; Said wheel frame comprises upper block frame and lower tumbler frame; The lower transverse beam installed inside of said beam frame assembly has the lower tumbler frame; Said backform is inboard to be equipped with the upper block frame with said lower tumbler frame correspondence position, and said needle beam assembly is installed on said upper block frame and the lower tumbler frame roller through the track plate of above and below.
The advantage of the utility model is:
1. this device saves the top rail and the vertical support that links to each other with crossbeam, backform of beam frame assembly, adopts the left and right beam of beam frame assembly directly to be connected with backform, makes the beam frame move on the whole, and compact conformation has strengthened bottom space;
2, on left bed die and right bed die, be provided with working window; And on the wedge mould, be provided with steam vent; Make when the lining cutting bottom; Make things convenient for the staff through the working window on the bed die with poker vibrator through working window to operations such as concrete vibrate, effectively reduce bubble and produce, improve the concrete lining quality;
3. the very heavy quantity of spiral that is provided with between this device template and beam frame is few, and the two space is big, and convenient working give to be installed air chimney etc. and stayed than large space;
3. this device is owing to adopt the side form oil cylinder and the bed die oil cylinder contraction demoulding; Whole demoulding amount is bigger; Template and concrete are difficult for producing scraping during trolley running, and because bottom space is bigger, so the bed die shrink space is bigger; Make to receive behind the mould that the bottom has than large space when the tunnel section size is big, make things convenient for staff's maintenance work, current.
Description of drawings:
Fig. 1 is the structural representation of the utility model lining cutting state.
Fig. 2 is the structural representation of the utility model demoulding state.
Fig. 3 is the utility model running status figure.
The specific embodiment:
Below in conjunction with accompanying drawing, specify a kind of specific embodiment of upper shed formula wholecircle needle beam lining trolley.
Shown in Fig. 1 to 3; A kind of upper shed formula wholecircle needle beam lining trolley mainly is made up of wedge mould 1, left and right sides bed die 2, left and right sides side form 3, backform 4, beam frame assembly 5, needle beam assembly 6, walking wheel frame 7, stopping means 8, side form oil cylinder 9, bed die oil cylinder 10, jackscrew 11, jacking cylinder 12, level and vertical centering guiding mechanism, hoist and traction machine structure, anti-floating system, hydraulic system and electrical system etc.; Jacking cylinder 12 is connected with beam frame assembly 5; Left and right sides bed die 2 comprises that left bed die and right bed die, left and right sides side form 3 comprise left side mould and right side mould; Beam frame assembly 6 is welded into " U " type by lower transverse beam, Zuo Liang and You Liang; The Zuo Liang of beam frame assembly 6 and the upper end of right beam and said backform 4 inboards are welded into integral body; Flexibly connect through bearing pin between the both sides of backform 4 and said left side mould and the right side mould; Flexibly connect through bearing pin between said left side mould and left bed die, said right side mould and the right bed die, said backform 4, left and right sides bed die 2, left and right sides side form 3 and wedge mould 1 connect to form circular shuttering, and said wedge mould 1 one sides are fixed on the said right bed die through bearing pin; Opposite side is installed on the said left bed die; Said left side mould is connected with beam frame assembly 5 through symmetrically arranged side form oil cylinder 9 respectively with the right side mould, connects through symmetrically arranged bed die oil cylinder 10 between said left bed die and left side mould, right bed die and the right side mould, and said left bed die is connected with beam frame assembly 5 bottoms through jackscrew 11 respectively with right bed die; Be equipped with the working window 13 that can be in communication with the outside on said left bed die and the right bed die, said wedge mould is provided with steam vent 14.
