Shown in Fig. 1; The tunnel mid-board structure that the utility model is related; It comprises some splicings mutually tunnel duct pieces 1, be positioned at least two mid-boards 2 that tunnel duct piece 1 and an end link to each other with tunnel duct piece 1, the lane plate 3 that is positioned at tunnel duct piece 1; One end links to each other with lane plate 3, the pedestal 5 that the other end and mid-board 2 links to each other, is connected the draw-in groove 4 of tunnel duct piece 1 and mid-board 2 respectively.Tunnel duct piece 1 spliced moulded the cylindrical of hollow that is.The cross section of mid-board 2 is " I " type, and it adopts prefabricated reinforced concrete structure, and along the bearing of trend in tunnel, the length of mid-board 2 is identical with the length of tunnel duct piece 1.Draw-in groove 4 is a prefabricated reinforced concrete structure also, which is provided with the groove of the upper end of accommodating mid-board 2, and 2 of this draw-in groove 4 and mid-boards are reserved an amount of gap, are filled with the fire resistant flexible material in this gap.In addition, draw-in groove 4 and said tunnel duct piece 1 are for being fixedly connected, and in this embodiment, said draw-in groove member 8 links to each other through expansion bolt 6 with tunnel duct piece 1.Prepared screw-bolt hole on pedestal 5 realizes that bolt connects mid-board 2 and pedestal 5, makes things convenient for assembling construction, accelerates the assembly unit progress.
Referring to accompanying drawing 1-6, the partition wall special-purpose machinery was mainly by crawler unit 7, mechanical arm 15 and can finely tune mobile manipulator 21 and form among present embodiment was described.Below be described in detail for said modules:
Because crawler type walking mechanism tractive force is big, grounding pressure is little, and shortcoming is that translational speed is slow.The speed of travel lower (0.6 kilometer/hour) that requires when but the median septum operation is installed, so walking mechanism adopts crawler type.
This device is the chassis special of mid-board construction machinery, by the frame 7 of H type, hydraulic moving motor 8, drive sprocket 9, thrust wheel 13, holder sprocket wheel 14, guide wheel 10, be wound in track rail assembly 12 between drive sprocket 9 and the guide wheel 10, revolving dial 11 etc. and partly form.The body of two running motors 8 is individually fixed in two rear sides of frame 7, and its output drives and connects drive sprocket 9, makes the hydraulic moving horse from the hydraulic oil of oil pump, and 8 rotate, and rotate thereby drive drive sprocket 9.Thereby drive sprocket 9 moves chassis whole with the relative motion of track rail assembly 12.Two guide wheels 10 are loaded on two front sides of frame 7, and its axle that is parallel to drive sprocket 9 is provided with.Thrust wheel 13 links to each other with frame 7 and is bearing on the track rail assembly 12, the weight of supporting machinery.Holder sprocket wheel 14 is contained on the frame 7 of both sides, and the axle of thrust wheel 13 and holder sprocket wheel 14 all is parallel to the axle of said drive sprocket 9.Revolving dial 11 is installed in the upper end of frame 7, and can horizontally rotate, and can relatively rotate thereby drive mechanical arm 15 parts.Motor, high-pressure oil pump, hydraulic oil container, hydraulic oil radiator, control system, balance weight are housed on the revolving dial 11.
The main structure parameters of crawler unit 7: track pitch 154mm, track shoe width 400mm, wheelspan 3300mm, gauge 2500mm, employing fluid motor-driven.To consider during the meter walking mechanism; The centre of gyration of mid-board special-purpose machinery is wanted as close as possible mid-board 2; So the gauge of 2500mm has guaranteed that mid-board special-purpose machinery both sides track rail assembly 12 can insert the mid-board member has been transported outside the battery truck in tunnel that mid-board 2 is more near the machinery rotation center.
Simultaneously crawler unit 7 different with the crawler unit of routine have different as follows:
1, the turning cylinder of revolving dial 11 is very near from drive sprocket 9 centers, and its distance approximates 1/3 of wheel base, and this ratio is about 1/2 in the common crawler unit.
2, left and right sides track gage broad, between crawler belt inboard width greater than the width of transport member vehicle, thereby can make the chassis more near member, stability and alleviated mechanical weight when having improved mechanical work greatly.
The core of mid-board special-purpose machinery is a manipulator 21; Manipulator 21 is the parts that in tunnel mid-board work progress, pick up, move mid-board 2; And when mid-board 2 is moved to the installation site; About carrying out, all around fine setting and around the rotary fine adjustment of three directions of mid-board member axis, to guarantee that mid-board 2 can accurately installation in position.The fine setting of all directions of manipulator 21 all adopts hydraulic jack to accomplish.
Manipulator 21 is made up of frame construction 22, a slide block 23 and a gripping mechanism 24:
Be distributed with 4 fine setting oil cylinders 25 that laterally arrange on the said frame construction 22, these four fine setting oil cylinders 25 are fixed on the same plane and eject direction all down.Wear a hole I (not shown) that ejects direction perpendicular to said fine setting oil cylinder 25 on the frame construction 22; Hole I is made up of two coaxial holes here; And has the open space of an end between these two holes; Be used for slide block 23 and move betwixt or rotation, be called hole I here for simplifying description, two holes being closed.Wherein also be provided with a slide bar oil cylinder I27 on the frame construction 22, the pin ear that the Shen goes out on the slide bar oil cylinder I27 other end and the slide block 23 links to each other.
Have on said slide block 23 bodies and the hole II vertical with hole I; And its two ends are symmetrical in hole II and extend respectively and be provided with coaxial round bar; And constitute slide bar I26, and two semiaxis round bars of slide bar I26 are plugged in respectively in two holes of hole I, and slide block 23 then is arranged in above-mentioned open space; And can slide bar I26 be that axle rotates, can vertically move (promptly moving axially) at the driving lower edge of slide bar oil cylinder I27 slide bar I26 simultaneously.
Also be provided with a slide bar oil cylinder II29 on the slide block 23, the cylinder body of slide bar oil cylinder II29 links to each other with slide block 23, and piston rod links to each other with the slide bar II28 of gripping mechanism 24.
Said gripping mechanism 24 has slide bar II28, the clamp 30 of being located at slide bar II28 two ends and the clamp oil cylinder 31 that is set in the said hole II, and clamp 30 and clamp oil cylinder 31 are used for the said mid-board 2 of clamping.Identical with above-mentioned slide bar I26 structure, gripping mechanism 24 can slide bar II28 be that axle rotates equally, and slide bar II28 can drive in the II of hole through slide bar oil cylinder II29 and move axially simultaneously.
Because slide bar I26, slide bar II28 are free to rotate in hole I, hole II, when four above-mentioned fine setting oil cylinders 25 eject, promote mid-board 2 and rotate around slide bar I26 and/or slide bar II28.For realizing above-mentioned structure, fine setting oil cylinder 25, hole I and hole II from top to bottom distribute successively simultaneously.Thus,, can make 25 top mid-boards 2 of different fine setting oil cylinders, rotate thereby reach the fine setting that makes mid-board 2 through handling the combination of different fine setting oil cylinders 25.
