Abstract
The utility model relates to a device for preventing a travelling crane steel wire rope from jumping from a slot, which is used for preventing the steel wire rope wound in the main fixed pulley for a travelling crane. The device comprises a contact electrode, a support, a power supply, a contactor and a circuit breaker, wherein, the contact electrode is arranged on the support, and the support is installed near to a fixed pulley, so that a vertical gap is formed between the contact electrode and the horizontal direction of the fixed pulley; the contactor is connected with the power supply, and the other end of the contactor is connected with the contact electrode through a conductive wire; and the circuit breaker is connected with a power supply circuit for the travelling crane and controlled by the contactor to disconnect the power supply circuit. The device for preventing the travelling crane steel wire rope from jumping from the slot can detect the fact that the steel wire rope is about to jump from the slot and stops the traveling operation, so that the phenomenon that the steel wire rope jumps form the slot can be found in time, and an unexpected accident can be avoided.
Description
Technical field
The utility model relates to a kind of traffic safety fender guard, specifically, relates to a kind of driving steel wire rope that prevents and takes off the device of groove, and it can work as the steel rope of driving when being about to break away from pulley, makes driving out of service, thereby prevents the appearance of contingency.
Background technology
Driving is the requisite hanging device of moving of large warehoused operation.The main at present various extensions that rely on formulation hang the working specification that rules and regulations restrict operating personal, prevent various contingencies.Yet, in some unconventional operation task, the blind area can appear monitoring inevitably, tend to hang operation, very easily cause driving steel wire rope and break away from the generation of rope race accident, gently then stop operation and take repairing apart owing to carelessness produces askew skewing, heavy then cause the damage of philtrum, equipment is impaired.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of driving steel wire rope to take off the anti-locking apparatus of groove, when the steel rope that this device can work as driving is about to break away from pulley, make drive a vehicle out of service, thereby prevent the appearance of contingency.
According to above-mentioned purpose, driving steel wire rope of the present utility model takes off the anti-locking apparatus of groove, and the Wound steel rope of the master file fixed pulley that is used for preventing driving a vehicle takes off groove, it is characterized in that this anti-locking apparatus comprises:
Contact electrode,
Support, this contact electrode are arranged on this support, and this support is installed near the fixed pulley, and making between this contact electrode and this fixed pulley horizontal direction has a vertical gap;
One power supply;
One contactless switch links to each other with this power supply, and its other end links to each other with this contact electrode by a lead; And
Circuit breaker is connected in the current supply circuit of driving, and this circuit breaker is subjected to the control of this contactless switch and disconnects current supply circuit.
Take off in the anti-locking apparatus of groove at described driving steel wire rope, described power supply is a voltage transformer, and 24 volts power supply is provided.
As mentioned above, can when steel rope just will take off groove, just can detect, and stop vehicling operation, therefore, can find in time that steel rope takes off groove, prevents the appearance of contingency because the driving steel wire rope that the utility model provides takes off the anti-locking apparatus of groove.

Fig. 2 is the installation site figure (overlook) of the support in the utility model with the driving fixed pulley.
Fig. 3 shows the scheme drawing that driving steel wire rope of the present utility model takes off the circuit part in the anti-locking apparatus of groove.
The specific embodiment
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, Fig. 1 shows driving steel wire rope of the present utility model and takes off the support in the anti-locking apparatus of groove and the structural representation of electrode.
Among Fig. 1 10 is support.Support 10 is by three right angle bonded assembly arms.Wherein, on a side of intermediate arm 12, contact electrode 20 is set.Intermediate arm 12 adopts non-conducting materials to make, and two side arms 11 and 13 is provided with mounting hole 14 in addition, by this mounting hole 14 support 10 is installed near the driving fixed pulley.Two side arms 11 and 13 for example can adopt material such as angle steel to make.
As shown in fig. 1, also include a lead 30.One end of lead 30 links to each other with contact electrode 20, and the other end will link to each other with contactless switch described later.
See also Fig. 2 below, Fig. 2 is the installation site figure (overlook) of the support in the utility model with the driving fixed pulley.As shown in Figure 2, support is installed near the fixed pulley, and makes between the horizontal direction of contact electrode 20 and this fixed pulley 40 a vertical clearance G is arranged.Under normal circumstances, the steel rope 50 of driving is embedded in the groove of pulley 40 and slides.But because a variety of causes, steel rope 50 can break away from (climbing out of) groove.The steel rope 50 that breaks away from groove this moment can touch nigh contact electrode 20 is set.Contact electrode 20 passes this activation signal by lead 30.The size of clearance G can be according to the factor settings such as thickness of the groove and the steel rope of fixed pulley.
See also Fig. 3 again, Fig. 3 shows the scheme drawing that driving steel wire rope of the present utility model takes off the circuit part in the anti-locking apparatus of groove.20 is contact electrode among Fig. 1 among Fig. 3, and contact electrode 20 is connected to contactless switch 60 by lead 30.Contactless switch 60 is connected to the power winding of voltage transformer 70.Voltage transformer 70 provides 24 low tension, for contactless switch 60 provides working power.In a further embodiment, working power also can adopt direct supply.On car owner's scrolling power of being expert at electric power loop, be connected in series a circuit breaker 80.This circuit breaker 80 is normally closed in normal circumstances, and its opening action is subjected to the control of contactless switch 60.Steel rope 50 in pulley contacts with contact electrode 20 because of a variety of causes takes off groove, makes in the contactless switch 60 and produces electric current.This moment, contactless switch 60 control circuit breakers 80 disconnected, and made driving lose the master file electrical source of power, and driving quits work.The staff can search steel wire and take off the groove reason, and steel rope is resetted.So, can prevent that steel rope from taking off groove, cause serious consequence.
