Description
Technical field
The present invention relates to building, transport field, particularly relate to a kind of gantry crane.
Background technology
Gantry crane is a kind of deformation of bridge crane, is again straddle truck.Straddle truck in the market mostly is wheel-track type, in use, needs to overlay track, big by site influence, the most inconvenient, although also to have some rubber-tyreds, but structure is complicated, bulky, when using in-site installation, needing to use giant caterpillar (or tire) to hang, splicing cost is high, and the cycle is long.It has the disadvantages that on the whole
1
, Wheeltrack type gantry crane, in use, need to overlay track, time and effort consuming, extremely inconvenience；
2
, rubber tyred gantry crane in the market, piece weight is relatively big, on-the-spot splicing extremely inconvenience；
3
, tyre crane in the market turn to underaction, during use, take up room big；
4
, owing to single-piece volume is big, when transition is transported, there is the phenomenon of superelevation, ultra-wide in both of which so that cost of transportation is the highest；
5
, current crawler belt (tyre crane) multiplex be elevator lifting, the steel wire rope maintenance that need to often oil is cumbersome.
Summary of the invention
It is an object of the invention to provide a kind of gantry crane, can be applicable to the lifting of construction and installation, bridge construction, harbour, harbour, Hai Gong etc., jacking, place transport, the assembly of big part.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of gantry crane, a pair lifting device including chassis, being arranged on described chassis, it is connected to the crossbeam between the lifting device top described in a pair, the suspender being connected on described crossbeam and power station, described chassis include two can the modular cart of independent ambulation, two described modular cart are separately positioned on the bottom of described lifting device.
Described modular cart is equipped with the remote controller for controlling its walking, lift or turn to.
Being provided with pedestal in described modular cart, the bottom of described lifting device is fixed on described pedestal.
Described lifting device includes the overcoat being fixed on described pedestal, the elevating ram being arranged in described overcoat and is fixed on the inner sleeve on the cylinder sleeve of described elevating ram, and described crossbeam is connected to described inner sleeve top.
The bottom of described elevating ram is provided with elevating ram seat, and described outer putting is provided with the first fixed oil cylinder for fixing described inner sleeve and the second fixed oil cylinder for fixing described elevating ram seat.
Described lifting device also includes, for it is carried out micro-electric control system and the stay wire sensor that lifting controls, being connected by signal between described micro-electric control system and stay wire sensor.
Described power station is hydraulic power station, and described hydraulic power station is connected in described modular cart.
Described lifting device, modular cart connect a described hydraulic power station, or one described hydraulic power station of common connection respectively.
What described suspender can be dismantled is connected on described crossbeam.
Hereinafter modular cart is described in detail:
Modular cart includes vehicle frame, is arranged on the multiple hitches below vehicle frame and steering mechanism, it is respectively connected with tire in the lower section of suspension holdfast, hitch and steering mechanism generally include by hanging oil cylinder and steering cylinder, and modular cart is equipped with special hydraulic power station and provides power for hanging oil cylinder and steering cylinder and drive its walking.
Modular cart can be equipped with the remote controller that specialized operations goes to walk, turn to, lift, and is walked by remote controller realization, turn to, is lifted various motion；The multi-mode steering function of modular cart can realize keeping straight on, walks crosswise, diagonal, center steering, pendulum are first, wag the tail, and waits and turns to pattern；The axis number of modular cart can be allocated with the difference of the specified lifting amount of straddle truck.
Modular cart realizes the structure of above-mentioned functions and can also refer to the relevant patent that applicant had previously applied for.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The present invention uses modular cart to do walking chassis so that it is be greatly enhanced the adaptability in place, it is not necessary to overlay track.This had both greatly reduced use cost, saved again the use time；And due to the feature of its multi-mode steering so that it goes slick, and operation takes up space little, and can lift by crane, jacking and short distance transhipment, and the route of transhipment do not limited by track, and reliability is high, the easy to operate hoisting operation requirement that disclosure satisfy that various working.
