Description

Hoister with brake

The utility model relates to elevator, promotes the capstan winch in the traction technique, winch; Be a kind of steel cable, wirerope or chain hoisting mechanism.

Common hoisting mechanism, especially steel cable or wirerope or chain hoisting mechanism, what more generally adopt is version used for a long time.Generally be by drop-gear box of driven by motor, drive rope drum by drop-gear box again and rotate, thereby with the steel cable tension or loosen.There are many shortcomings in above-mentioned existing steel cable or wirerope or chain hoisting mechanism: complex structure, heaviness, manipulate dumb, the manufacturing cost height, Applicable scope is restricted.

The purpose of this utility model provides a kind of yi word pattern band brake winch simple in structure, light, easy for operation.

Technical solution of the present utility model is: a kind of yi word pattern band brake winch, comprise motor, rope drum and support and underframe, and it is put unlike the prior art and is: transmission device is housed in the rope drum, has drg between transmission device and motor.

Transmission device in the utility model adopts many row's push rods and differential planetary composite driving mechanism.Certainly also can adopt single transmissioning mechanisms such as many row's push rod transmission devices separately, or adopt other composite driving mechanisms.

Comprise by push rod, push rod bobbin in many rows push rod in the utility model and the differential planetary composite driving mechanism, be contained in the needle roller on the rope drum inwall, many rows post rod mechanism that the eccentric wheel is formed, reach the differential planetary mechanism of forming by sun wheel, satellite gear, planet bearing pin, internally toothed annulus.

Push rod bobbin in many row's post rod mechanisms of the present utility model and the internally toothed annulus in the differential planetary mechanism are connected as a single entity.

Internally toothed annulus in the differential planetary mechanism perhaps of the present utility model is contained on the rope drum inwall with the needle rollers of arranging in the post rod mechanisms jointly.

Drg in the utility model adopts the normal obvolvent drg of enclosed.

Drg in the utility model be located on the electric machine support or in.

In the normal obvolvent drg of enclosed of the present utility model a closed shell is arranged, there is the spring leaf that brake strip is equipped with in an inboard to become normal obvolvent state with the brake disc that is connected as a single entity with motor output shaft in the shell, one end of spring leaf is fixed on shell or the underframe, the other end with one fixedly extension spring be connected; A leverage also is contained on the shell, and its short actuation arm links to each other with extension spring bonded assembly one end with spring leaf, and the long actuation arm of leverage can make its electromagnetic mechanism that produces displacement link to each other with one.

Drg closed shell of the present utility model and motor housing and rope drum support are connected as a single entity.

The utility model has the advantages that: volume is little, in light weight, simple in structure, cost is low, flexible and convenient operation, applied widely, noise is little, output torque is big, transmission accuracy is high, especially skid after adopting normally closed brake can not occur drenching with rain and foreign material are fallen into the space stuck phenomenon, and lower than the version cost that adopts the band brake motor, reliability is high.
