Embodiment one:
As shown in Figure 5,6:In the present embodiment:Travel mechanism includes modular cart 2, and pedestal 10 passes through first connecting portion 100 It is fixed with modular cart 2.
Modular cart 2 includes vehicle frame, multiple hitches and the steering mechanism being arranged on below vehicle frame, under suspension holdfast Side is respectively connected with tire, and hitch and steering mechanism are generally included by hanging oil cylinder and steering cylinder, and modular cart 2 is equipped with specially Hydraulic power station provide power for hanging oil cylinder and steering cylinder and drive its walking, modular cart 2 and lifting mechanism 11 can be with A hydraulic power station, or one hydraulic power station of connection jointly are connected respectively.Modular cart 2 can be equipped with specialized operations and go to go The remote control walk, turn to, lifted, walking is realized by remote controller, turned to, lifting various motion;The multi-mode of modular cart 2 Turning function can realize straight trip, row, diagonal, center steering, pendulum is first, wags the tail, etc. steering pattern;The axis number of modular cart 2 can Allocated with the difference of the specified lifting amount of straddle truck.
When crane main body is when modular cart 2 is used together, can operate according to the following steps:
1st, first the pedestal 10 of gantry body is individually placed in two modular carts 2, passes through first connecting portion in pedestal 10 Fixed with modular cart 2 with connector 20;
2nd, modular cart 2 is made to run to the correct position of needs lifting or transhipment object, so that slip suspender 13 can be with Hoisting point position face on weight;
3rd, modular cart 2 is closed down;
4th, the lift height of gantry body and the lateral attitude of slip suspender 13 are adjusted respectively, are made it and to be lifted by crane Lifting hole(eyelet) on weight aligns;
5th, it is attached with slip suspender 13;
6th, make weight be increased to it is suitable be highly put on the car that other are used for transporting or stop it is all wherein operate, carry out In next step;
7th, operation module car, suitable position is moved into, then weight is fallen;
8th, modular cart 2 is made to reorganize and outfit the position for being moved to and specifying, so as to complete the hoisting operation.
So, pedestal is capable of in the modular cart of independent ambulation installed in two, by the synchronous operation of two modular carts, is come real Existing displacement storage or stacking of the crane after weight is sling, when doing walking chassis using modular cart, its adaptation to place Property greatly enhances, and without overlaying track, this had both greatly reduced use cost, saved usage time again;And because it is more Pattern turn to the characteristics of so that it goes slick, operation take up space it is small, and can lift by crane, jack and short distance transhipment, and transport Route do not limited by track, reliability is high, the easy to operate hoisting operation requirement that disclosure satisfy that various working.
Embodiment two:
As shown in Figure 7,8:In the present embodiment:Travel mechanism includes guide rail 30, walking oil cylinder 31, the upper plane of guide rail 30 On be provided with gib block, the guide groove of the bottom of pedestal 10 is engaged with gib block, can avoid pedestal 10 and its reorganize and outfit sliding During skew, it is ensured that pedestal 10 be expert at oil cylinder 31 push-and-pull under can advance along predetermined direction.Walking oil cylinder 31 Cylinder sleeve is connected on guide rail 30, and the tailpiece of the piston rod of walking oil cylinder 31 is connected in second connecting portion 101, certainly, oil cylinder 31 of walking Cylinder sleeve be connected in second connecting portion 101, the tailpiece of the piston rod of walking oil cylinder 31 is connected on guide rail and equivalent.
When crane main body and guide rail 30 coordinate lifting and short distance displacement to operate according to the following steps:
1st, needed below with thing pads such as rubble or sleepers in the suitable position laying guide rail 30 of weight for needing to lift by crane, guide rail 30 Real, the spacing of guide rail 30 determines according to the length of crossbeam 12 of gantry body;
2nd, by gantry body, assembly is good on guide rail 30, by second on the tailpiece of the piston rod and pedestal 10 of oil cylinder 31 of walking Connecting portion 101 is connected, and the cylinder sleeve of walking oil cylinder 31 is connected with the fixing threaded hole on guide rail 30;
3rd, the suspender of slip suspender 13 of gantry body is connected with the corresponding suspension centre of lifted weight respectively;
4th, weight is sling;
5th, walking oil cylinder 31 is made gantry body is advanced by shrinking(Or retreat), oil cylinder 31 of being expert at is retracted to most In short-term, twist off be fixed on guide rail 30 it is up walk oil cylinder 31 cylinder sleeve bolt, be fixed to next fixation of direction of advance Position;
6th, the action of repeated contraction oil cylinder, by circulating repeatedly, until weight to be moved to the position specified, then behaviour is passed through Make slip suspender 13, it laterally can be also met status requirement, then fallen;
7 then by gantry body remove by transport back otherwise or using oil cylinder 31 of walking carry out reversely repeatedly Shrink, gantry body is returned to initial position, then removed.
So, pedestal is arranged on guide rail, passes through the walking oil cylinder of the left and right that is respectively connected with the pedestal of left and right two two Walking advances, to realize displacement storage or stacking of the crane after weight is sling, compared with embodiment one, the present embodiment It is relatively low to reorganize and outfit cost, better economy, but it is poor to the adaptability in place, efficiency is relatively low.
The utility model can two sets or more set complete a lifting or displacement task together, in the course of the work, pass through One remote control can control the action of multiple devices simultaneously, and synchronism is good.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this. All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it It is interior.
