Detailed description of the invention
A kind of double beams double bogies bridge crane as Figure 1-Figure 5, including the consistent left dolly 1 of structure, right dolly 2, lifting crane span structure 3, described lifting crane span structure about 3 two ends are provided with complete machine travelling mechanism 4, drive and run before and after crane; The crossbeam 5 of left and right directions is installed on lifting crane span structure 3 crossbeam top, and described crossbeam 5 is provided with trolley track, and left dolly 1, right dolly 2 left and right on trolley track is run; Described left dolly 1, right dolly 2 are provided with hoist engine 100, and described hoist engine 100 includes lifting motor 101, reductor 102, reel 103, and the steel wire rope 104 that described reel 103 is wound around connects the equipment needing lifting by assembly pulley 105. Described trolley track includes the trapped orbit 51 being arranged on crossbeam 5 two ends, is arranged on the swing-around trajectory 52 in the middle part of crossbeam; Being connected with the piston rod of hydraulic cylinder 53 bottom swing-around trajectory 52, described hydraulic cylinder 53 bottom is connected with rotating disk 54, and described rotating disk 54 is arranged on crossbeam 5.
Described crossbeam 5 is arranged below the first cable trough 6, and described first cable trough 6 is equipped with the cable 7 moved with left dolly 1, and crossbeam is provided above the second cable trough 8, and described second cable trough 8 is provided with the cable 7 moved with right dolly 2.
During crane loading equipment, first left dolly 1, right dolly 2 are connected with equipment two ends by suspension hook, after lifting, left dolly 1, right dolly 2 can along crossbeam 5 transverse shiftings, crossbeam 5 vertically moves along lifting girder simultaneously, when equipment needs to rotate 180 ° in horizontal plane, control left dolly 1, right dolly 2 moves on swing-around trajectory 52, swing-around trajectory 52 is risen certain height by hydraulic cylinder 53, then swing-around trajectory 52 is allowed to rotate 180 ° relative to rotating disk 54 in horizontal plane, it is achieved turning around of equipment.Equipment can install pull rope in advance when rotating on equipment, realized it by the mode manually pulled to rotate, rotating disk 53 can also be allowed to be connected with the electric rotating machine 9 being arranged on crossbeam 5 by reducing gear, swing-around trajectory 52 is driven to rotate by electric rotating machine 9, described reducing gear can be multi-stage gear formula reductor, it is also possible to be Worm-gear type reductor.
In order to prevent left dolly 1, right dolly 2 wherein one or two but without when running on swing-around trajectory 52, swing-around trajectory 52 misoperation, can arrange between hydraulic cylinder 53 and rotating disk 54 central authorities LOAD CELLS 55, described left dolly 1, right dolly 2 assembly pulley 105 on be respectively provided with first LOAD CELLS the 106, second LOAD CELLS 107. When the weight that the weight controlling LOAD CELLS 55 measurement of system validation central authorities is added with first LOAD CELLS the 106, second LOAD CELLS 107 adapts, namely left dolly 1, right dolly 2 are all located on swing-around trajectory 52, just allow electric rotating machine 9 action.
When equipment is transferred to another place from a place by crane, need equipment rise, mobile, decline, in decline process, the gravitional force of available equipment, make its automatic descending, therefore better embodiment is to be provided with gearshift between described lifting motor 101 and reductor 102. Described gearshift includes the first axle 201, described one end of first axle 201 is connected by shaft coupling with the outfan of lifting motor 101, the other end of described first axle 201, by the first combined cover 202 that can slide along the first axle 201 axial direction, is connected with one end of the second axle 203; The described other end of the second axle 203 is connected with the input of reductor 102, and the second axle 203 is additionally provided with joint gear 204, and described joint gear 204 is connected with the power shaft of retarder 206 by the second clutch collar 205. Described first clutch collar 202, the second clutch collar 205 can be the inertia-type lock loop synchronizer used in automotive transmission field, it is also possible to be the lock unit of gear sliding type.
When equipment needs to decline, first clutch collar 202 action, by the first axle 201, second axle 203 separated, second clutch collar 205 will engage between gear 204 and retarder 206 and be connected simultaneously, such equipment moves downward under gravity, and the speed that it moves downward can be controlled by retarder 206, described retarder 206 can be hydraulic type retarder, it can also be electric motor type retarder, when using electric motor type retarder, can by retarder 206 and commutator, accumulator connects, gravitional force when namely can be declined by equipment is converted to electric energy, stored by accumulator, effectively save the energy.
