Description
Technical field
It the utility model is related to crane technical field, more particularly to a kind of device of hierarchical control multilayer reel.
Background technology
Existing gantry crane is typically powered using cable drum, with the increase to gate-type crane loading tonnage,
Its installed capacity also improves constantly, therefore the quantity of service cable increases therewith, typically using the multiple cables of multi-cable collocation
Reel removes cooperated power supply, drives cable drum to rotate again using motor driving reductor, but in use, due to being rolled up
In process of production inevitably there is error in its diameter with cable, the diameter error and then cause to be entangled on each cable drum
The thickness of cable have differences, the every tightness by volume cable becomes inconsistent, abnormal with the rotation of cable drum
Pressure suffered by cable continues to increase, energy when finally even can break cable, therefore how solve to wind multi-cable at the same time
Pulling force on the single reel of adjust automatically suffered by abnormal cable, avoids cable from being pulled off, and turns into current urgent problem to be solved.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device of hierarchical control cable drum, and the device exists
In operation process, the rotation of the energy single reel of adjust automatically, and then adjust the pulling force size on reel suffered by cable.
Technical solution of the present utility model is to provide a kind of dress of the hierarchical control cable drum with following structure
Put, including motor, the reductor that is connected with motor, one end of the output shaft of described reductor is provided with multiple magnetic force couplings
Clutch, described each magnetic coupling are equipped with cable drum outside, and described magnetic coupling includes and output shaft is fixed and connected
The first magnetic patch connect and the second magnetic patch being connected with output shaft by bearing, the second described magnetic patch and described cable drum it
Between be fixedly connected.
After being designed more than, the utility model compared with prior art, has advantages below：
Because the first magnetic patch is fixedly connected on output shaft, magnetic force be present between the first magnetic patch and the second magnetic patch, the magnetic force
So that cable drum follows output shaft synchronous to rotate, the pulling force when some or some cable exceptions by volume suffered by it is more than it
By the pulling force suffered by volume cable, and with the rotation of output shaft, the abnormal pulling force persistently increases when being more than magnetic force for it, then right
Should abnormal pulling force reel not followed by output shaft synchronous rotate produce but speed difference is produced between output shaft, with reduce
The abnormal pulling force makes it equal to other pulling force by suffered by volume cable.
As an improvement, described cable drum both ends are respectively equipped with side plate, between described adjacent two cable drum
A side plate is shared, such a structure forms multilayer reel structure, saves the cost of reel and reduce the volume of whole device.
As an improvement, being externally provided with protection cap in the side plate close to reductor side, foreign matter is avoided to enter output shaft and reel
Between, output shaft and reel are worn, extends service life of the present utility model.
As an improvement, being additionally provided with collector ring on the other end of described reductor, cable is avoided to be turned round in rotary course
Wound.

Embodiment
As shown in Figure 1 to Figure 3, a kind of device of hierarchical control cable drum, including motor 5, be connected with motor
Reductor 6, one end of the output shaft 6.1 of described reductor 6 are provided with multiple magnetic couplings, and the other end is provided with collector ring
8；Cable drum 1 is equipped with outside described each magnetic coupling, described magnetic coupling includes being fixedly connected with output shaft
The first magnetic patch 2 and the second magnetic patch 3 being connected with output shaft by bearing and first magnetic patch 2 it is adjacent with the second magnetic patch 3
Hold as opposite pole, the first described magnetic patch 2 and the second magnetic patch 3 are permanent magnet, the second described magnetic patch 3 and described cable
It is fixedly connected between reel 1.The described both ends of cable drum 1 are respectively equipped with side plate 1.1, described adjacent two cable drum
Between share the cable drum that side plate 1.1 forms multilayer, formed between two side plates in multi-layer cable reel for holding
The grooving 1.2 of cable is put, the reinforcement 1.3 of multiple radial directions is provided with side plate 1.1, in the side plate 1.1 close to reductor side
It is additionally provided with protection cap 7 outside.
Motor 5 drives reductor 6 to operate, and the output shaft 6.1 of reductor is when rotating, because the first magnetic patch 2 is solid
Surely it is connected on output shaft 6.1, therefore the first magnetic patch 2 follows the synchronous axial system of output shaft 6.1, that is, rotating speed is identical.Described
Connected by bearing 4 between second magnetic patch 3 and output shaft 6.1, be fixedly connected between cable drum 1, due to the first magnetic patch 2 with
Magnetic force between second magnetic patch 3 be present, therefore when the first magnetic patch 2 follows output shaft 6.1 to rotate, multiple electricity in by volume cable
In the case that cable does not occur elastic differ, the second magnetic patch 3 and the synchronous axial system of the first magnetic patch 2；Occur in by volume cable elastic
During the phenomenon to differ, multiple magnetic couplings can adjust the rotating speed of the second magnetic patch 3 in it respectively, specifically adjust process
For with the rotation of output shaft 6.1, the degree that cable slack differs can increase, when the pulling force suffered by abnormal cable is more than first
During magnetic force between the magnetic patch 3 of magnetic patch 2 and second, the second magnetic patch 3 will not produce therebetween followed by the synchronous axial system of the first magnetic patch 2
Raw differential skids, until the pulling force suffered by abnormal cable is equal to the pulling force suffered by other normal cables, the drawing suffered by normal cable
Power is necessarily less than the magnetic force between the first magnetic patch 2 and the second magnetic patch 3, and now the second magnetic patch 3 is synchronous followed by the first magnetic patch 2
Rotate, the hierarchical control process to multi-layer cable reel is realized with this.Described the first magnetic patch 2 and the second magnetic patch 3 can be whole
The permanent magnet of block, it can also be combined by multiple small magnets, the pulling force that the quantity of small magnet can bear according to twined cable
To determine.
