The utility model provides a hoisting mechanism, service braking dish and service braking utensil have the samely and the deformation volume syntropy, and the greatly reduced that influences each other between them has solved the intervene problem of service braking ware with the service braking dish.
Description
Technical field
This utility model relates to hoisting machinery technical field, specifically relates to one and is applicable to various general and special elevator gate-type or bridge-type one crane hoisting mechanism.
Background technology
Lifting mechanism, is the mechanism of the most critical of crane.The structure design type of lifting mechanism, it is determined that crane uses the integrality of process.
Currently, do not set the closed-type cylindrical gearing lifting mechanism of exposed gear, because it is simple and compact for structure, mechanism driving efficiency high, be phased out old-fashioned open type gear driving version.
Existing closed-type cylindrical gearing lifting mechanism, it mainly includes motor, service brake, duty Moving plate, service brake support, decelerator, reel group, deadman's brake, safety arrestment dish, bearing block, bearing bracket, reducer stent, bracing frame and pulley gear etc..
Its main connected mode is: bearing bracket, reducer stent and service brake support are all connected with bracing frame by the way of welding respectively.Such version, once crane comes into operation, and there will be following technical problem in its use afterwards:
Service brake support is welded on plane on bracing frame, and reducer stent is also welded to plane on bracing frame, and duty Moving plate is that the high speed shaft with decelerator is connected, and duty Moving plate and service brake cooperate braking.The bracing frame deformation when lifting mechanism works, now between duty Moving plate and service brake, deflection is different with deformation direction, thus is easily caused between service brake and duty Moving plate and interferes, and affects crane and normally works.
Utility model content
This utility model aims to the defect existing for above-mentioned prior art and deficiency, a kind of crane hoisting mechanism is provided, lifting mechanism provided by the utility model, duty Moving plate and service brake have deformation quantity identical and in the same direction, influence each other between them and be substantially reduced, solve the interference problem of service brake and duty Moving plate.
This utility model realizes by using following technical proposals:
A kind of crane hoisting mechanism, it is characterized in that including bracing frame, drive mechanism, decelerator, reducer stent, duty Moving plate, service brake and for carrying the service brake support of service brake, described decelerator is installed on reducer stent, reducer stent is supported on support frame as described above, described service brake support is detachable to be connected on described reducer stent, and the connection plane of service brake support and reducer stent is not higher than the upper plane of reducer stent.
The high speed shaft of described decelerator is double shaft versions: specifically high speed shaft one end of decelerator is connected with the drive shaft of drive mechanism, and fixing connection duty Moving plate on the other end of high speed shaft, duty Moving plate coordinates with described service brake.
Compared with prior art, what this utility model was reached has the beneficial effect that:
1, service brake support uses and is bolted on reducer stent, when lifting mechanism works, even if bracing frame deforms, now accelerator support and service brake are owing to being connected together, thus be that there is deformation quantity identical and in the same direction between them, so, theoretically, the duty Moving plate being installed on high-speed shaft of speed reducer and the service brake being installed on service brake support also have deformation quantity identical and in the same direction, influence each other between them and be substantially reduced, solve the interference problem of service brake and duty Moving plate.
2, service brake support is not higher than plane on reducer stent with the connection plane of reducer stent, it is simple to the dismounting of decelerator.
