The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the traveling gear of hoisting crane, comprise: walking cart 1, the lower end of walking cart 1 is provided with running wheel 2, walking cart 1 is arranged on the track 3 by running wheel 2, track 3 is arranged on the track girder 4, the support 5 of one end of walking cart 1 is provided with fixedly hinge 6 and fixedly hinge 7 and movable hinge 8 and movable hinge 9, fixedly be provided with trammel beam 10 between hinge 6 and the movable hinge 8, fixedly be provided with trammel beam 11 between hinge 7 and the movable hinge 9, be provided with roller 12 in the lower end of movable hinge 8, be provided with roller 13 in the lower end of movable hinge 9, roller 12 and roller 13 are separately positioned on the both sides of track 3 and cooperatively interact with track 3, the other end of trammel beam 10 and trammel beam 11 is fixed together by regulating connecting rod 14, wherein a trammel beam 10 is provided with drop-gear box 15, drop-gear box 15 is connected with electrical motor 16 on being arranged on support 5, on electrical motor 16, also be provided with drg 20, electrical motor 16 is connected with drop-gear box 15, what the drop-gear box 15 in the present embodiment adopted is the vertical-type planetary drop-gear box, and the output shaft 17 of drop-gear box 15 is provided with Drive pinion 18 and cooperatively interacts with the tooth bar 19 that is arranged on track girder 4 one sides.
The concrete working process of the traveling gear of the hoisting crane of said structure is: drive 15 rotations of vertical-type planetary drop-gear box by the electrical motor 16 that is arranged on the support 5 earlier, thereby the Drive pinion 18 that drives on the output shaft 17 that is arranged on the vertical-type planetary drop-gear box 15 rotates, Drive pinion 18 cooperatively interacts with the tooth bar 19 that is arranged on a side on the track girder 4, thereby driving walking cart 1 walks on track 3, the running wheel 2 that is arranged on walking cart 1 lower end cooperatively interacts with track 3, is arranged on the effect that drg 20 on the electrical motor 16 can play brake.
When distortion appears in track 3, the traveling gear of the hoisting crane of said structure can be regulated the direction that walking cart 1 advances automatically, the running wheel 2 that is arranged on walking cart 1 lower end is adapted with track 3, concrete control process is: by the fixedly hinge 6 on the end support 5 that is arranged on walking cart 1 and fixedly hinge 7 and movable hinge 8 and movable hinge 9, be arranged on the fixedly trammel beam 10 between the hinge 6 and movable hinge 8, be arranged on the fixedly trammel beam 11 between the hinge 7 and movable hinge 9, be arranged on movable hinge 8 the lower end roller 12 and be arranged on movable hinge 9 the lower end roller 13 and regulate the regulating mechanism that connecting rod 14 is formed a parallelogram together, when track 3 deforms, the Drive pinion 18 that can cause being arranged on the output shaft 17 of drop-gear box 15 breaks away from mutually with the tooth bar 19 that is arranged on track girder 4 one sides, can not provide stable propulsive effort for walking cart 1, the cart 1 that causes walking can not be walked normally, at this moment, micro-distortion can take place in the adjusting connecting rod 14 that is arranged between trammel beam 10 and the trammel beam 11, thereby drive and to be arranged on track 3 both sides and to deflect with roller 12 and roller 13 that track 3 cooperatively interacts, thereby drive trammel beam 10 and trammel beam 11 deflect and adapt to the distortion of track 3, the vertical-type planetary drop-gear box 15 that is arranged on the trammel beam 10 also can follow trammel beam 10 to deflect together, thereby the Drive pinion 18 that guarantees to be arranged on the output shaft 17 of drop-gear box 15 cooperatively interacts with the tooth bar 19 that is arranged on track girder 4 one sides, continues to drive the walking normally on track 3 of walking cart 1.
