Abstract
In the prior art, hoisting mechanisms with the hook free falling function have two structures, wherein one structure is achieved by directly adding a sleeve outside a hoisting gear box and controlling the sleeve and a reel through a clutch, and the other structure is achieved by controlling high speed gear ring of the gear box through the clutch; non of the two structures has the wire rope anti-slip function, the wire rope is easy to detach and the rope is at mess; moreover, the conventional hoisting mechanisms have the designing problems of low work efficiency, high energy consumption, incomplete and loose structure, difficulty in manufacturing, high cost, and the like. According to the invention, a dry clutch is used to directly control the reel, so as to achieve the function of hook free falling; when the free falling hook is at work, non of a planet reduction gear, a wet multi-sheet brake, and a driving hydraulic motor is at work; the high-performance hook free falling hoisting mechanism is high in efficiency, low in energy consumption, and simple in structure, realizes wire rope anti-slip and protection function by controlling through a caliper disc brake; the high-performance hook free falling hoisting mechanism solves the congenital deficits of a conventional product in aspects of scheme, structure, and technology, and can excellently meet the requirement of a user in the particular aspect of energy conservation and emission reduction.
Description
Technical field
The present invention relates to a kind of weight-lifting equipment hoisting mechanism.
Background technology
Free off the hook hoisting mechanism is applied more and more extensive in construction machinery and equipment weight-lifting equipment, can greatly shorten the hollow hook lowering time, increases work efficiency, and especially in the use of dynamic compaction machinery, more can embody its advantage.There are two types both at home and abroad at present: the first type: Chinese patent 201120037986.1 discloses the hoisting mechanism of the free off the hook function of a kind of new-type band, as shown in Figure 1.This structure is directly at the outside coupling tunnel 5 that increases of existing hoisting speed reducer 4, by axle 6, internal expansion type power-transfer clutch 10, bearing 81 and elevator 7 and left socle 1, right support 2, be connected and realize free unhook function, need to outside hoisting speed reducer, additionally increase coupling tunnel bearing, axle, huge structure, not compact, manufacture difficulty, cost is high; Reel is controlled and is relied on internal expansion type power-transfer clutch completely, poor reliability, and steel rope easily departs from, disorder cable; What reductor adopted is the differential type power dividing structure of gear ring output, and load-carrying capacity exists loss.The second type, can be referring to Chinese patent 201220616448.2, and name is called the crane hoisting mechanism that can realize free off the hook, and its structure as shown in Figure 2.This structure reel 4 directly connects with reductor 3 shells, controls hoisting speed reducer 3 internally toothed annuluss and realizes, although structure relative compact by power-transfer clutch 5, but while realizing free off the hook, reductor 3 gear rings and the equal high speed rotating of internal gear driving system thereof, efficiency is low, and energy consumption is large; Reel is controlled and is relied on power-transfer clutch 5 completely, poor reliability, and steel rope easily departs from, disorder cable; What reductor still adopted is the differential type power dividing structure of gear ring output, and load-carrying capacity exists loss.
All there is inefficiency in these two kinds of structures, energy consumption is large, and structure imperfection, not compact is manufactured difficulty, high in cost of production problem.

Adopted the free off the hook hoisting mechanism of above technical scheme to have the following advantages and effect:
1, can realize free off the hook function;
2, can realize preventing wire rope from falling defencive function;
3, adopt dry type clutch, avoided the generation of work high temperature, unlimited space structure rapid heat dissipation, lock torque is large, and unlatching, closed flexible, reliable, controls separately reel, when mechanism's hollow hook lowering, only reel assemblies is carried out high speed rotating, and reductor, HM Hydraulic Motor, drg all do not need work, and efficiency is high, less energy consumption;
4, bikini bearing configuration, has increased mechanism's rigidity and intensity, has guaranteed reliability, the alerting ability of power-transfer clutch work;
5, decelerator shell is directly connected by bearing with reel, and compact conformation is manufactured simply, and cost is low;
6, Integral type mounting frame guarantee shown in large, the good rigidly of structural strength, working accuracy is high, separation type supporting seat guarantees that mechanism is easy for installation, improves space availability ratio, safeguards, easy to use;
7, planetary reducer input end permanent seat and gear ring spline joint axial positioning structure, adopt packing ring, flathead screw location to replace back-up ring positioning form, increased the rigidity of gear ring, improved axial location reliability;
8, adopt three grades of series connection planetary transmission structures to realize free off the hook function, simple in structure,
Easily control
