Abstract
The utility model discloses a kind of ring rail crane rotation trolley driving device, including speed reducer, the front of the speed reducer is connect with driving arm one end, and the driving arm other end is fixed on trolley bracket；It is fixed with gear on the output shaft of speed reducer, which engages with fixed gear ring on the drive wheel；Driving wheel center is equipped with bearing, and the bearing outer ring is fixed, and inner ring is fixed in support shaft on the drive wheel, and the other end stretching of support shaft is fixed on trolley bracket.The utility model is by the way of exposed gear external toothing, circumferentially by drive arrangement, driving torque can effectively be reduced, in the case where same driving torque demand, the output requirement of driving device can be advantageously reduced, while can effectively reduce the structure size of driving device, compared to traditional driving method, power unit is externally arranged space, there is preferably maintenance convenience, efficiently avoid turning round many shortcomings of trolley driving device now.
Description
Technical field
The utility model belongs to crane accessory technical field, and in particular to a kind of ring rail crane rotation trolley driving dress
It sets.
Background technique
In the lifting of nuclear power of new generation, petrochemical industry and ocean engineering moduleization, the requirement for hanging loading capability to equipment is continuous
It is promoted.Ring rail crane has the characteristics that hang the application that carrying capacity is big, operating radius is big, hoisting moment is big, in the field because of it
It is more and more extensive.Consequent, bigger hoisting power need the device for revolving and driving of ring rail crane to have bigger drive
Dynamic torque.Existing ring rail crane rotation trolley driving device is slowed down using the mounting means being arranged in shaft center hole
Machine output shaft with driving wheel is concentric is fixedly connected, the output torque of speed reducer directly drives driving wheel；Speed reducer and prime mover
Structure size limited by trolley size of wheel, when needing bigger output torque to carry out drive ring rail crane, bigger grade
Other speed reducer and prime mover structure size sharply increase, and make balance difficulties between structure size and wheel strength, even result in
The speed reducer for meeting design requirement can not be selected.In addition, space is narrow since revolution trolley drive arrangement is in central shaft hole
It is small, operating difficulties is installed, especially when power unit repairs, needs to dismantle entire driving device, maintenance difficult.
Summary of the invention
The purpose of the utility model is to provide a kind of simple structure and reasonable designs, and existing revolution trolley can effectively be overcome to drive
The ring rail crane rotation trolley driving device of dynamic device shortcoming.
To achieve the above object, the technical solution adopted in the utility model are as follows: the device includes speed reducer, its main feature is that:
The front of the speed reducer is connect with driving arm one end, and the driving arm other end is fixed on trolley bracket；The output of speed reducer
Gear is fixed on axis, which engages with fixed gear ring on the drive wheel；Driving wheel center is equipped with bearing, the bearing
Outer ring is fixed, and inner ring is fixed in support shaft on the drive wheel, and the other end stretching of support shaft is fixed on trolley bracket.
Using the above structure, in use, speed reducer output shaft band moving gear driven gear ring rotate, and then drive driving wheel around
Support shaft axis rotation, so that drive ring rail crane rotation trolley is around circular orbit center movement.The utility model is used and is opened
The mode of formula gear external toothing circumferentially by drive arrangement can effectively reduce driving torque, turn round in same driving
In the case where square demand, the output requirement of driving device can be advantageously reduced, while can effectively reduce driving device
Power unit is externally arranged space compared to traditional driving method by structure size, has preferably maintenance convenience, has
Avoid to effect the revolution many shortcomings of trolley driving device now.The utility model simple structure and reasonable design, is filled up
The blank of such device is worth extensive and promotes and applies.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the utility model gear ring structure schematic diagram.
Specific embodiment
As shown, the utility model includes speed reducer 1, the front of the speed reducer 1 passes through location hole and mounting hole spiral shell
Bolt 9 is connect with 3 one end of driving arm, and 3 other end of driving arm is fixed on trolley bracket 7.Make the entire driving unit of speed reducer 1
It is capable of fixing on driving arm 3.It is fixed with gear 4 on the output shaft 11 of speed reducer 1, is adopted between the gear 4 and output shaft 11
It is fixedly connected with key or interference positioning method.Gear 4 is engaged with the gear ring 2 being fixed on driving wheel 5.5 center of driving wheel
Equipped with bearing 8, which is fixed on driving wheel 5, and inner ring is fixed in support shaft 6, and the other end of support shaft 6 stretches out
It is fixed on trolley bracket 7.By being respectively provided at concentric boss 14 and groove 15 thereon between the gear ring 2 and driving wheel 5
Positioning, and be fixed together by being distributed in mutual corresponding screw hole and bolt 10 on gear ring 2 and driving wheel 5, it can protect in this way
Card gear ring 2 is overlapped with 5 center line of driving wheel.8 two sides of bearing, which are equipped with, is fixed on the bearing cap on driving wheel 5 by bolt 13
Plate 12, wherein the 12 center aperture of bearing cover of inside, so that support shaft 6 can protrude on the inner ring for being fixed on bearing 8.
The speed reducer 1 can be multiple to be distributed at a certain angle, can be not change speed reducer and original dynamic using multiple speed reducers 1
In the case where type number, the promotion of driving torque is realized by increasing multiple driving units, to meet actual work need
It asks.
