Description
Technical field
This utility model relates to crane technical field, particularly relates to a kind of lifting hook crane lifting machine
Structure.
Background technology
Lifting hook crane belongs to general-purpose overhead crane, by trolley, crane span structure, traveling mechanism of the larger traveller
And electrical control equipment etc. four part composition.The position of drivers' cab is according to using environment, Ke Yigu
It is scheduled on both sides or the centre of crane span structure, in particular cases can also move with trolley.Lifting hook crane
Lifting mechanism generally include motor, decelerator, reel and cable wire, motor by decelerator drive volume
Cylinder rotates so that cable wire is wound on reel, and there is suspension hook cable wire lower end, thus drives weight slowly to promote；
At present weight rises, the distance that declines is all by Artificial Control, controls if up, dropping distance
The improper weight that may result on hook interferes with crane and collides, and there is peace during use
Full hidden danger.
Utility model content
There are the problems referred to above to solve crane hoisting mechanism of the prior art in this utility model, carries
Supply one can control suspension hook rising, dropping distance the most automatically, use safer suspension hook to rise
Heavy-duty machine intelligence lifting mechanism.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of lifting hook crane intelligence lifting mechanism, including motor, decelerator, reel, reel sets
Having hoist cable, motor to be connected with reducer input shaft, one end of reel is fixing with reducer output shaft to be connected,
The other end of described reel is fixed with support shaft, and the outer end of support shaft is connected with bearing block, described bearing
The side of seat is provided with connection seat, and the outer end of described support shaft is through connecting seat, the outer end of described connection seat
It is provided with the lifting stop rotating the number of turns for controlling support shaft.Motor is turned by decelerator band movable reel
Dynamic, thus rolling hoist cable, after spool turns one fixing turn, trigger lifting stop automatic spacing,
Spacing without Artificial Control, use safer.
As preferably, described lifting stop includes worm gear case, limit switch base, in worm gear case
Worm screw is coaxially connected with support shaft, and the flange on worm gear case connects with being connected seat, the worm gear in worm gear case
Being connected with worm-wheel shaft, the outer end of worm-wheel shaft is stretched in limit switch base, and described worm-wheel shaft is fixed with
Cam, in described limit switch base, the corresponding position with cam is provided with limit switch.Worm screw and support shaft,
Reel synchronous axial system, when spool turns N circle (number of turns required for rising, falling-threshold position) is received
During volume hoist cable, worm screw just drives cam to turn around, when cam turns around, at the big footpath of cam just
Pressure limit switch, it is achieved rise automatic spacing, when spool turns puts down hoist cable, spool turns N
Circle, bulge loop depresses limit switch after rotating a circle again, it is achieved decline automatic spacing.
As preferably, between reducer input shaft and reducer output shaft, it is provided with accident brake.Hanging
In rope lifting process, if it occur that emergency, can be braked by accident brake, so that
Reducer input shaft cannot rotate with reducer output shaft, ensures safety.
Therefore, this utility model has the rising of control suspension hook, dropping distance the most automatically, uses more
Add safe beneficial effect.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation lifting stop in this utility model.
In figure: motor 1, decelerator 2, reel 3, support shaft 4, bearing block 5, connect seat 6,
Lifting stop 7, accident brake 8, worm gear case 70, limit switch base 71, worm screw 72, method
Orchid 73, worm gear 74, worm-wheel shaft 75, cam 76, limit switch 77.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
A kind of lifting hook crane intelligence lifting mechanism as shown in Figure 1, including motor 1, decelerator 2,
Reel 3, reel is provided with hoist cable, and motor is connected with reducer input shaft, one end of reel 3 with subtract
Speed device output shaft is fixing to be connected, and the other end of reel 3 is fixed with support shaft 4, the outer end of support shaft with
Bearing block 5 connects, and the side of bearing block 5 is provided with connection seat 6, and the outer end of support shaft passes and connects seat,
The outer end connecting seat 6 is provided with the lifting stop 7 rotating the number of turns for controlling support shaft；Decelerator is defeated
Enter to be provided with between axle and reducer output shaft accident brake 8.
As in figure 2 it is shown, lifting stop 7 includes worm gear case 70, limit switch base 71, worm gear case
Worm screw 72 in 70 is coaxially connected with support shaft 4, the flange 73 on worm gear case 70 be connected seat 6
Connecting, the worm gear 74 in worm gear case 70 is connected with worm-wheel shaft 75, and limit is stretched in the outer end of worm-wheel shaft 75
In bit switch seat, worm-wheel shaft 75 is fixed with cam 76, right with cam in limit switch base 71
Limit switch 77 should be provided with in place；Spacing opening can be depressed when the bigger diameter end of cam turns at limit switch
Close.
In conjunction with accompanying drawing, principle of the present utility model is as follows: motor drives spool turns by decelerator,
Thus rolling hoist cable；In uphill process, after spool turns one fixing turn, worm screw just drives
Cam turns around, and when cam turns around, just depresses limit switch at the big footpath of cam, it is achieved rise
Automatic spacing, during declining, after spool turns one fixing turn, after bulge loop rotation one circle again
Once depress limit switch, it is achieved decline automatic spacing；During raising and lowering, if it occur that
Emergency, then can pass through accident brake fast braking.This utility model has control the most automatically
Suspension hook processed rises, dropping distance, uses safer beneficial effect.
