The specific embodiment
Referring to Fig. 1 to Fig. 3, a kind of differential trolley container crane of the present invention comprises main hoisting mechanism, wheeling mechanism, and luffing mechanism and traveling mechanism of the larger traveller also comprise the differential speed reducer 1 that is arranged in the machine room.
The present invention takes and uses differential technique, especially adopts differential speed reducer 1, and main hoisting mechanism and wheeling mechanism are united two into one, and structure is greatly simplified, and has saved trolley travelling retarder, dolly reel, trolley travelling steel rope and assembly pulley.
One of them input shaft 11 of differential speed reducer 1 is connected with vehicle motor 2, and another input shaft 12 of differential speed reducer 1 is connected with main lifting motor 3.One of them output shaft 13 of differential speed reducer 1 is connected with reel A, and another output shaft 14 of differential speed reducer 1 is connected with reel B.Reel A and reel B are trolley travelling and hoist and use reel, and raising line is the dolly hauling rope just.Reel A and reel B by hauling rope separately descending operation carry out the lifting goods, also trolley travelling operation separately, trailer wagon operation make goods along the operation of crossbeam track cross level, can also carry out dipping and heaving and dolly pulling motion simultaneously.
Principle of work of the present invention is as follows:
1. dolly does not move, and when only doing lifting, with car brake 5 brakings, restarts main lifting motor 3 earlier.This moment is because differential speed reducer connects reel A and reel B, do by solid arrow contrary in the same way/clockwise rotate.Mechanism does the motion of receiving/releasing rope, by lay winding wire ropes, freight container is risen or decline.
2. it is motionless to hoist, only separately during the dolly pulling motion, and drg 6 brakings of main lifting motor, starting vehicle motor 2.This moment is because differential reel A and the reel B of making does the opposite sense motion by dotted arrow.Mechanism makes reel B receiving/releasing steel rope and makes reel A put/receive steel rope.Make dolly make pulling motion by lay winding wire ropes to land side or extra large side.
3. compound motion: when hoisting and car brake is opened simultaneously, lifting motor, vehicle motor turn round simultaneously, and this moment, the work of two reels was stacks of two motions.Carry out composition operation thus, make handling goods make compound motion.
Referring to Fig. 4, when hoisting or during descending motion (solid arrow), reel A and reel B equidirectional (suitable, conter clockwise) rotate, thereby make goods rise or descend.
When the dolly pulling motion (dotted arrow), reel A and reel B counter-rotation, thus dolly is moved to extra large side along big beam orbit, or move to the land side.
Its principle is in conjunction with referring to Fig. 3 and Fig. 4, and differential technique of the present invention is with the differential mode of machinery and goods lifting, level run.Input shaft 11 is connected with vehicle motor 2, and another input shaft 12 is connected with main lifting motor 3, and output shaft 13 is connected with reel A, and output shaft 14 is connected with reel B.Differential speed reducer 1 will hoist to move with two actions of trolley travelling and unite two into one.
When working independently when hoisting, input shaft 11 is braked, thereby gear Z1, Z2, Z3, Z4, Z8, Zb1, Zb2 can not rotate.After the lifting motor running,, make reel A and reel B finish to rise and descend with rotating speed in the same way and move by a series of planetary mechanism transmissions.
When dolly worked independently, input shaft 12 was braked, thereby the sun wheel Za2 of gear Z5, Z7 and right lateral star mechanism can not rotate, and the sun wheel Za1 of Z5, Z6 and left lateral star mechanism can not rotate simultaneously.When vehicle motor input shaft 11 makes reel A on the output shaft and the reverse same rotational speed of reel B (shown in the turning to of dotted arrow among Fig. 4) by train running, realized trolley travelling.
When carrying out compound motion, vehicle motor 2 and main lifting motor 3 make the aforementioned two kinds of motion stacks on the reel all to the retarder input torque, change turning to and different rotating speeds of reel A and reel B.When a reel speedup, another reel just subtracts same rotating speed.
Because mechanical differential mode need could be moved by the differential speed reducer of big weight and size, in order to cancel differential speed reducer, differential technique of the present invention reaches lifting and level run in the electrical differential mode.In conjunction with referring to Fig. 5, the present invention has replaced the function of mechanical differential mode mainly by two motor linkages operations, makes entire mechanism greatly simplify.The reel varying duty technical requirements of electrical differential mode is as follows:
When hoisting, at n with the dolly stable motion
Hoist=n
DollyThe time, can see that it is (nA=0 or the nB=0) that does not change that a reel is arranged between reel A and the reel B.
When hoist and dolly when the land side is moved, reel A rotating speed slows down and is n
Hoist-n
Dolly, reel B faster rotational speed is n
Hoist+ n
Dolly
When descend and dolly when extra large side is moved, reel A rotating speed slows down and is n
Descend-n
Dolly, reel B faster rotational speed is n
Descend+ n
Dolly
When descend and dolly when the land side is moved, reel A faster rotational speed is n
Descend+ n
Dolly, reel B rotating speed slows down and is n
