The specific embodiment
With reference to Fig. 1-6, a kind of half rubber-tyred electric block gantry crane of the present utility model, comprise girder 11, and the left support frame 12 and the right support frame 13 that are arranged at girder 11 both sides, on girder 11, mounted electric block 16, left support frame 12 bottoms are provided with left crossbeam 14, and right support frame 13 bottoms are provided with right crossbeam 15.
The below of left crossbeam 14 is fixedly installed rail 4.The two ends of left crossbeam 14 are respectively equipped with horizontal wheel mechanism 6 and the steel wheel 3 that rail 4 slides relatively, and be wherein provided with steel wheel driver train 2 in one end at left crossbeam 14, steel wheel driver train 2 is connected with the steel wheel 3 of this end, by this steel wheel driver train 2, the power that provides steel wheel 3 to rotate.Steel wheel driver train 2 comprises drive motor 1 and under drive gear 22, and drive motor is connected with steel wheel 3 by under drive gear 22.
The two ends of right crossbeam 15 are respectively equipped with tyre type wheel 5, and are provided with tire wheel driver train 7 on right crossbeam 15, by described tire wheel driver train 7 and right crossbeam 15 wherein the tyre type wheel 5 of one end be connected.Tire wheel driver train 7 comprises drive motor 2 71, sprocket wheel 73 and chain 72, and drive motor 2 71 is connected with tyre type wheel 5 by sprocket wheel 73, chain 72.By controlling the rotation of drive motor 2 71, then transmitted by sprocket wheel 73 and chain 72, drive tyre type wheel 5 to rotate.
Horizontal wheel mechanism 6 comprises horizontal wheel bearing 61 and two horizontal wheel 62, horizontal wheel bearing 61 is fixedly installed on left crossbeam 14, on horizontal wheel bearing 61, be fixedly installed fixing or movable being arranged on pillar 8 respectively of 8, two horizontal wheel 62 of two pillars, and be symmetrically arranged in rail 4 both sides.When horizontal wheel 62 is fixedly mounted on pillar 8, in crane operational process, by the restriction of 62 pairs of large Car Track left and right sides of two horizontal wheel, steel wheel 3 is remained along rail 4 direction operations, effectively prevent steel wheel 3 derailings.While being fixedly connected with pillar 8 because horizontal wheel 62 is fixing, between horizontal wheel 62 and rail 4, be cliding friction, in order to reduce this cliding friction, the another kind of preferred version of taking, is movably arranged on horizontal wheel 62 on pillar 8.Particularly, horizontal wheel 62 is movably arranged on pillar 8 by bearing, can effectively reduce like this friction force between horizontal wheel 62 and rail 4, can better keep and adjust steel wheel 3 simultaneously, makes steel wheel 3 all the time along rail 4 direction operations.
The load carrying ability of considering various transfer cranes is different, can on left crossbeam 14, increase several steel wheels 3, on right crossbeam 15, increase several tyre type wheels 5, the quantity of steel wheel 3 and tyre type wheel 5 is determined according to the load carrying ability of transfer crane, can effectively increase like this bearing force of left crossbeam 14 and right crossbeam 15.
Electric block 16 transfer cranes that the utility model has solved conventional all-steel wheel 3 cannot adapt to the familiar lacunas of special geological surrounding, are only allowing the place of laying track to lay a rail 4, and the crossbeam of steel rail laying 4 one sides adopts steel wheel 3; Another root crossbeam adopts tyre type wheel 5, without rail 4.So both met the demand of different geographical environments, and can make again to remain in transfer crane operational process in the direction of rail 4 layings, not offset track simultaneously; And 5 pairs of place strong adaptabilities of tyre type wheel, thereby realized above-mentioned special occasions to electric block 16 transfer crane requirements.
