Abstract
The utility model relates to a kind of line rod crane armature of direct current motor winding circuits.Excitation commutation winding, which has, rises connector under commutation winding joint, main hook rising connector, anode connector and main hook, the main hook, which rises, concatenates the first rising D.C. contactor normally open contact between connector and positive pole, it is risen under the main hook and concatenates the first decline D.C. contactor normally open contact between connector and positive pole, the commutation winding joint directly concatenates the second rising D.C. contactor normally open contact and the second decline D.C. contactor normally open contact in parallel with connector is risen under main hook；Band-type brake coil is concatenated between the anode connector and commutation winding joint.Its structure is simple, and failure rate is low, long service life.
Description
Technical field
The utility model relates to a kind of armature of direct current motor winding circuit, in particular to a kind of line rod crane direct current is electromechanical
Pivot winding circuit.
Background technique
Line rod crane belongs to outdoor machinery, and opening hook up and down is DC MOTOR CONTROL, and high failure rate is directly used once burning out
Direct current generator replacement, and original mode of connection wiring is shone, on startup, upper and lower hook speed is slow, not interesting.It opens the throttle
When, oil circuit suppresses fire, as the feeling of fire extinguishing.Since contactor electric current is very big, D.C. contactor contact is burnt out.It live can only tie up
It repairs, seriously delays production.
Summary of the invention
The shortcomings that in order to overcome the prior art, the utility model provide a kind of line rod crane armature of direct current motor winding electricity
Road.Its structure is simple, and failure rate is low, long service life.
The technical solution adopted by the utility model to solve its technical problems is that: excitation commutation winding has commutation winding to connect
Head, main hook, which rise, rises connector under connector, anode connector and main hook, the main hook, which rises, concatenates the between connector and positive pole
One rises D.C. contactor normally open contact, and the first decline of concatenation direct current between connector and positive pole is risen under the main hook and is contacted
Device normally open contact, the second rising D.C. contactor that the commutation winding joint directly concatenates parallel connection with liter connector under main hook are normal
Open contact and the second decline D.C. contactor normally open contact；Band-type brake line is concatenated between the anode connector and commutation winding joint
Circle.
The utility model structure is simple, and failure rate is low, long service life；Direct current generator once damage, can with quick-replaceable,
It does not influence to produce.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is utility model diagram.
Specific embodiment
As shown in Figure 1, excitation commutation winding 8 has commutation winding joint 10, main hook to rise connector 9, anode connector 7 and main hook
Lower liter of connector 6, the main hook, which rises, concatenates the first rising D.C. contactor normally open contact 4 between connector 9 and positive pole 2,
It is risen under the main hook and concatenates the first decline D.C. contactor normally open contact 12, the commutation between connector 6 and positive pole 2
Winding joint 10 directly concatenates the second rising D.C. contactor normally open contact 5 and the second decline in parallel with connector 6 is risen under main hook
D.C. contactor normally open contact 11；Band-type brake coil 3 is concatenated between the anode connector 7 and commutation winding joint 10.
