A kind of fence type reel bank bridge elevation mount
Technical field
The utility model relates to hoisting crane mechanical field, specifically, is a kind of fence type reel bank bridge elevation mount.
Background technology
About the hoisting crane of bank lifting freight container, it is responsible for front crossbeam and is called bank bridge elevation mount around the mechanism that crossbeam hinge has been removed and put down, by direct motor drive, by coupler, carry out coiling action through actuator drives cable drums such as retarders and realize luffing.
In prior art, the common arrangement form of bank bridge elevation mount is, a base-fixed retarder 84, and its high speed shaft 81 connects motor 8, slow-speed shaft 82 connect single laminate roll around common reel 83(see Fig. 1 and Fig. 2).And have following shortcoming about bank bridge elevation mount of the prior art: first, because common reel 83 is windings of single layer, so it is limited to hold rope amount, and in order to ensure that the drift angle that steel rope leaves common reel 83 grooving meets the requirements, so common reel 83 diameter is larger, general more than one meter; Secondly, the high speed shaft 81 of motor 8 and common reel 83 difference connection reducer 84 and slow-speed shaft 82, not on same straight line, retarder 84 volume ratio is larger, the volume ratio of whole bank bridge elevation mount is comparatively large, causes bank bridge elevation mount base and the corresponding increase of machine house volume thus.
In sum, need badly a kind ofly hold that rope amount is large, volume is little, the bank bridge elevation mount of lightweight, long service life.Report is yet there are no about the bank bridge elevation mount that can solve the problems of the technologies described above.
Summary of the invention

Described bank bridge elevation mount is also provided with emergent motor.
The utility model advantage is:
1, bank bridge elevation mount of the present utility model, selects fence type reel, and steel rope can carry out multilaminate coiled, and the Rong Shengliang of reel obviously strengthens;
2, bank bridge elevation mount of the present utility model, select fence type reel, ensure steel rope leave drum rope groove drift angle meet the requirements time, reel vertical direction can save the space of about 1m, that drum diameter can be done when same castor is less, thus machine house chassis and machine house also can correspondingly reduce, and effectively reduce volume;
3, due to dual slope grooving and the special disc of fence type reel, what can ensure that steel rope can be smooth-going is wound on reel, and damage and disorder cable can not be had to internal layer steel rope, steel rope and grooving angle control within 1.5 degree simultaneously, control the situation within 2.5 degree compared to this drift angle general of common reel, to the service life of steel rope, there is clear superiority;
4, bank bridge elevation mount of the present utility model, adopt planetary reduction gear, when transmitting onesize power, volume is little, lightweight, compact conformation; Especially high speed shaft and the transmission of slow-speed shaft coaxial line, make the size of retarder length direction greatly reduce.
