Background technology
Traditional raise boring machine is all rail wheel type chassis, does not has the ability of autonomous, from aboveground to underground construction position Must be transported by cage, when down-hole same track up conversion construction location, it is necessary to by extraneous pull strength.At vertical machine and During receipts machine, it is necessary to use rail meter retaining rail wheel undercarriage frame, rail meter is relied on to provide a trimming moment allow main frame Found machine and receipts machine smoothly and do not tumble.Go into the well on either transport, on-the-spot mobile and receipts machine founds machine, and rail wheel type chassis is the most aobvious Obtain troublesome, need to put into the most supporting facility and manpower.
For solving the problem of raise boring machine walking, a kind of for raise boring machine disclosed in the patent No. 201420342626.6 Mobile type walking mechanism, it includes main frame, mainframe, rotating disk, sole and rail wheel, and described sole extends to two ends point Not forming the first extension and the second extension, the both sides of described first extension and the second extension are connected with wheel by wheel shaft Tire, the wheel shaft on described first extension is provided with knuckle.It achieves raise boring machine on trackless road surface by tire Walking, but the walking mechanism of rubber-tyred requires height to Land leveling row and solidity, in order to avoid rut is the deepest, increase running resistance with Steering drag, affects the stability that complete machine travels.
External portable raise boring machine uses split-type structural, i.e. power unit assembly, main frame assembly, the mobile end Dish each several part is all independent, and manufacturing cost is the highest and carries out disassembly and assembly labor intensive material resources at the construction field (site).And it is domestic Portable raise boring machine does not the most occur.Visible developing can have very important meaning by autonomous formula large aperture raise boring machine Justice, be domestic row those skilled in the art need the technical barrier captured badly.
Utility model content
The purpose of this utility model is that and overcomes the deficiencies in the prior art, it is provided that a kind of portable large aperture courtyard bores Machine, its power unit assembly, main frame assembly and mobile platform unitary design, complete machine autonomous, it is not necessary to dismantle or lift.
To achieve these goals, this utility model provides a kind of portable large aperture raise boring machine, total including main frame Become, power unit assembly and mobile platform, described main frame assembly include swiveling head, propelling cylinder, lead, shore oil cylinder, Pitching oil cylinder, base and top board, described swiveling head is connected with described propelling cylinder, and the two ends of described lead are respectively with described Top board is connected with base, and the two ends of described propelling cylinder are connected with described top board and base respectively, described in shore oil cylinder with Described top board is connected, and described mobile platform includes track rail assembly, sole and leg assembly, and described track rail assembly is with described Sole is connected, and the two ends of described pitching oil cylinder are connected with described base and sole respectively, described power unit assembly Including power unit underframe, described power unit underframe is connected with described sole, and described leg assembly includes four supporting legs, Two described supporting legs are installed in the support oil cylinder installing hole of described sole, and supporting leg described in another two is installed on described power list On unit's underframe, being installed on described sole two described supporting legs can individually regulate, and is installed on described power unit underframe Another two described in supporting leg adjusted in concert, the bottom support of four described supporting legs is on ground.
Further, described power unit assembly also includes being arranged at described power unit underframe Shang Fakong center, water Cooler, Diesel engine pump group, electric-motor pump group, secondary hydraulic oil container and driver's cabin.
Further, described sole is provided with the duct that described power unit assembly oil pipe passes.
Further, described sole is by the end face bolt hole being connected with described track rail assembly arranged on it and side Bolt hole, is connected with described track rail assembly bolt.
Further, described sole by the end face bolt hole being connected with described power unit underframe of its upper setting and Side bolt holes, is connected with described power unit underframe bolt.
Further, described sole being provided with main frame hinged seat and pitching cylinder support, described sole passes through institute Stating main frame hinged seat to be connected with described base, described sole is connected with described pitching oil cylinder by described pitching cylinder support Connect.
Further, there are electric control operation and manual operation in described Fa Kong center, and described valve control is centrally through remote controller control The action of each executive component, can be with manual operation when electric control operation breaks down.
Further, hydraulic motor, described hydraulic motor and described power unit assembly it are provided with in described track rail assembly It is connected.
Further, described pitching oil cylinder is provided with balanced valve.
Swiveling head of the present utility model combines driving rotary bit or cutterhead by two low speed high torque hydraulic motors, real High pulling torque of the present utility model output and wide-aperture operation are showed.
Oil cylinder of shoring of the present utility model when bore operation, the top of its piston masthead to tunnel, the boots plate of base with The lower concrete in tunnel is bolted, and has been achieved in that main frame assembly fixing at vertical direction, has enhanced complete machine and execute Stability during work industry, is the effective means preventing duct deflection.
Propelling cylinder of the present utility model applies propelling pressure and applies the anti-power of lifting, maximum propelling to reaming to boring Power or the anti-power of carrying are big, simultaneously advance oil cylinder also with guide function.Lead acts primarily as guide effect, simultaneously with propelling oil Cylinder shared creeps into rotary torque during reaming.Pitching oil cylinder is responsible for receipts machine and vertical machine, equipped with balanced valve on pitching oil cylinder, protects Card receipts machine and vertical machine stable action.Base is in addition to supporting the weight on top, and the boots plate below base is by foundation bolt and ground Surface concrete is fastenedly connected, it is ensured that during construction, complete machine stablizes.
