Abstract
The utility model discloses a drum type winding drum used in a hoisting system, which comprises a motor, a reduction gearbox, a chassis, a winding drum, a steel wire rope and a supporting bearing seat. The diameter of the beginning section and the destination section for lifting the hopper of the winding drum is smaller than that of the middle operation section. The winding drum provided by the utility model has the characteristics of guaranteed work efficiency, lower start current, stability in running, small impact, and longer service life of the steel wire rope.
Description
Technical field
The utility model belongs to the vehicle for construction technical field, especially relates to a kind of novel elevator system drum-type reel.
Background technology
The concrete mixer of vehicle for construction market use is now used general, in the concrete mixer hopper elevator system, steel rope generally is wrapped on the cylindrical drum at present, and starting current is bigger when hopper promotes, operating voltage can descend moment, causes work not steady; When hopper runs to terminal point, stop moment, the discharging of opening the door, impulsive force is bigger, influences the service life of parts such as reductor, steel rope.
The content of invention
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of can guaranteed efficiency, reduce starting current, work operates steadily, impulsive force is little, the elevator system cydariform reel in prolongation steel rope service life.
The purpose of this utility model is to realize like this, a kind of elevator system drum-type reel, be that motor, drop-gear box, chassis, reel, steel rope and supporting shaft holder are formed, be characterized in that the hopper of reel promotes The initial segment part and the diameter of terminal point section diameter partly less than middle target phase part.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is to change existing cylindrical straight reel into drum-type not isometrical drum-type reel, the starting point section and the terminal point section that promote at hopper adopt the minor diameter grooving, adopt the major diameter grooving at middle target phase, it is excessive to have solved hopper heavy duty lifting starting current like this, operating voltage descends, problem such as impulsive force was bigger when terminal point stopped, this drum-type reel does not have impact load when electric motor starting and discharging, promote stable working state, dynamic characteristics is good, prolong the service life of steel rope, when especially needing directly to start for high-power lifting motor, reduce starting current, realized reduced-voltage starting.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model
The specific embodiment:
Embodiment, a kind of elevator system drum-type reel, with reference to Fig. 1, be directly to connect with drop-gear box 2 at motor 1, on the output shaft of drop-gear box 2, be fixed with reel 4, one end of steel rope 5 is fixed on reel 4 and can be wrapped in along the grooving on the reel 4 on the reel 4, the other end of steel rope 5 is connected to hopper, the hopper of reel 4 promotes the diameter of the diameter of The initial segment and terminal point section part less than middle target phase, be that reel 4 is formed by being provided with a major diameter reel in the middle of two minor diameter reels, the output shaft of reel 4 is fixed on the supporting shaft holder 6, and above-mentioned parts integral installation is on chassis 3, and this constitutes a kind of structure of the present utility model.
Principle of work of the present utility model is as follows: when elevator system is worked, motor 1 drives drop-gear box 2 to begin to start, steel rope 5 drives hopper and promotes on the minor diameter of the end of reel 4, at this moment reel 4 diameters are little, hoisting speed is lower, start stable, need starting current little, steel rope 5 carries out the transition on the midway location major diameter position of reel 4 naturally then, and the hopper running velocity is accelerated, steel rope 5 carries out the transition on the other end small diameter portion of reel 4 naturally when closing on the lifting terminal point, at this moment the running velocity of hopper reduces, during to terminal point, and the master cock action, hopper slowly stops, and opens hopper discharge automatically.
Claims (1)
1. elevator system drum-type reel, be that motor (1), drop-gear box (2), chassis (3), reel (4), steel rope (5) and supporting shaft holder (6) are formed, it is characterized in that the hopper of reel (4) promotes The initial segment part and the diameter of terminal point section diameter partly less than middle target phase part.
