The invention is characterized in that an electromotor is arranged on a connection seat with bolts by a connection tray, a braking control system is fixed on the connection seat by an axis pin, a vertical planetary reducer is fixed with an upper fixed ring by bolts, a locating block and a locating plate are used for fixing a rotating anchor device so as to prevent loosening, a pinion is fixed on the vertical planetary reducer by the bolts, and a lower fixed ring is welded with a rotary table of the crane, and a first oil drain pipe, an oil filling pipe and a second oil drain pipe are respectively connected with the vertical planetary reducer by the bolts. The invention has simple, compact and reasonable structure, can greatly improve working efficiency and safety performance of the crane, reduce failure rate of the swing mechanism, and simplify installation of the swing mechanism.
Description
Technical field
The present invention relates to a kind of rotating mechanism of hoisting crane, specifically be applicable to all kinds of high pedestal jib cranes, 360 degree revolution Control work devices of floating crane stationary crane are the indispensable important component parts of hoisting crane.
Background technology
At present, port operation in the modern times, the various hoisting crane that need such as factory's manufacture are equipped with is owing to be that how tame manufacturer makes, multiple drawing manufacturing causes all kinds of hoisting crane kinds loaded down with trivial details, and quality is low, crane rotation mechanism structure confusion particularly, maintenance difficult, work efficiency is low, greatly reduces the hoisting crane service efficiency.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of installation and maintenance of being convenient to are provided, can improve the service efficiency of hoisting crane, and also can improve the rotating mechanism of the hoisting crane of crane safety in-use performance simultaneously.
According to technical scheme provided by the invention, the rotating mechanism of hoisting crane comprises terminal pad, connection seat, friction disk type moment coupler, vertical planetary reducer, last mounting ring, miniature gears, braking control system, first oil drain tube, fuel filler pipe, second oil drain tube, following mounting ring, locating piece, locating plate and rotation anchoring device, electrical motor is installed on the connection seat with bolt by terminal pad, braking control system is fixed on the connection seat by bearing pin, braking control system is connected to the driver's cab foot-operated switch by high pressure fuel pipe, friction disk type moment coupler flat key, the tooth axle is separately fixed on vertical planetary reducer and the electrical motor, behind a whole set of positioning correcting of last mounting ring and vertical planetary reducer, last mounting ring and rotating platform of crane welding are fixing, vertical planetary reducer is fixed with bolt and last mounting ring, locating piece, locating plate is used for fixing the usefulness of rotating anchoring device, prevent to become flexible, miniature gears is fixed by bolts on the rotation anchoring device, following mounting ring and rotating platform of crane welding, first oil drain tube, fuel filler pipe, second oil drain tube respectively with vertical planetary reducer with being threaded.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Because this mechanism passes through motor, moment coupler reductor lower drive shaft, the revolution work to hoisting crane is finished in a series of connection such as miniature gears, improved the work efficiency of hoisting crane greatly, safety performance has reduced the fault rate of swing type mechanism, has simplified the installation of swing type mechanism.
Description of drawings

Fig. 3 is a structure moment coupler scheme drawing of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 3, comprise terminal pad 1, connection seat 2, friction disk type moment coupler 3, vertical planetary reducer 4, go up mounting ring 5, miniature gears 6, braking control system 7, first oil drain tube 8, fuel filler pipe 9, second oil drain tube 10, mounting ring 11, locating piece 12, locating plate 13, rotation anchoring device 14 etc. down.
The present invention adopts electrical motor to be installed on the connection seat 2 by terminal pad 1 usefulness bolt, braking control system 7 is fixed on the connection seat 2 by bearing pin, braking control system 7 is connected to the driver's cab foot-operated switch by high pressure fuel pipe, friction disk type moment coupler 3 is used flat key, the tooth axle is separately fixed on vertical planetary reducer 4 and the electrical motor, behind last mounting ring 5 and the vertical planetary reducer 4 a whole set of positioning correctings, last mounting ring 5 is fixing with the rotating platform of crane welding, vertical planetary reducer 4 usefulness bolts and last mounting ring 5 are fixing, miniature gears 6 is fixed by bolts to vertical planetary reducer 4 lower shaft end, following mounting ring 11 and rotating platform of crane welding, first oil drain tube 8, fuel filler pipe 9, second oil drain tube 10 is threaded with vertical planetary reducer 4 usefulness respectively.
Friction disk type moment coupler of the present invention 3 adopts half-couplinves, brake wheel, power wheel, compositions such as platen, friction lining, stage clip up and down, last half-coupling is fixed on the motor shaft, following half a coupler is fixed on the reductor input shaft, power wheel is fixed on down in the half a coupler, friction lining is put in the platen centre up and down, is installed in the middle of power wheel and the following half a coupler.
The drg of braking control system 7 of the present invention, by brake scotch, support, hydraulic ram is regulated compositions such as bolt, handwheel, and brake scotch is installed on the brake support frame, brake support frame is fixed on the reductor special stand, hydraulic ram, and handwheel is fixed on the support by bracket holes.
Vertical planetary reducer of the present invention (M510 type) 4 the latter halfs are made up of lower connecting barrel, adapter plate, miniature gears regulating sleeve etc.; Lower connecting barrel is fixed on the reducer shell, is fixed on the rotating platform of crane, and miniature gears and adjusting ring are fixed on the speed reducer output shaft.
Rotating mechanism of the present invention needs only light step and steps on switch when operation, just can control cylinder action by high-pressure oil passage and control crane rotation work, but in the not drg hand brake revolution of the moving control system of work schedule of hoisting crane, prevent that hoisting crane from turning to.
