The utility model relates to a kind of overhead traveling crane lifting mechanisms, control more particularly to the extreme position of overhead traveling crane lifting mechanism.Overhead traveling crane lifting mechanism extreme position special alarming device, overhead traveling crane lifting mechanism (2) electric signal connects hand control switch (1) and electromagnetic switch (3), travel switch (5) electric signal connection electromagnetic switch (3) being mounted on overhead traveling crane lifting mechanism, displacement sensor (4) electric signal connection electromagnetic switch (3) and the warning device (6) being mounted on overhead traveling crane lifting mechanism.The beneficial effects of the utility model are: lifting mechanism caused by reducing because of travel switch damage does not stop making the equipment such as wirerope, suspension hook.
Description
Technical field
The utility model relates to a kind of overhead traveling crane lifting mechanisms, control more particularly to the extreme position of overhead traveling crane lifting mechanism.
Background technique
It is responsible for making for 22 overhead traveling cranes of full factory in the stainless wire rolling plants mechanical work area of Shanxi Taigang Stainless Steel Co., Ltd
With, maintenance, repair work, main target is to ensure that overhead traveling crane zero failure, zero complaint, provides high-efficiency high-quality service for production.And day
The lifting mechanism of vehicle is to ensure that one of the important component that overhead traveling crane operates normally, our factory overhead traveling crane largely belong to setting always for the sixties again
Standby, the limes superiors mode of braking of lifting mechanism is all cut off the power by travel switch to complete, i.e., when suspension hook rises to
When designated position, travel switch rotates screw rod by electromagnetic switch, and overhead traveling crane lifting mechanism is made to obtain contactor power-off release, raising
Motor stops, and suspension hook also stops immediately.It is that route is simple, convenient for safeguarding, cost that this lifting mechanism, which stops the advantages of mode,
It is lower.But have the shortcomings that it is larger i.e.:When travel switch is because of failure failure, after suspension hook rises to extreme position, stroke is opened
Pass is failure to actuate, and cannot disconnect in time power supply stops suspension hook, and suspension hook continues to rise will result in twist bad wirerope, pulley blocks,
Or wirerope is caused to twist disconnected suspension hook falling accident；If braking moment adjustment is improper, after travel switch power-off, due to inertia
Suspension hook will continue to operation a distance, and accident most probably occurs；Operator's operation error cannot timely find suspension hook
Whether also run when operation to extreme position.
Summary of the invention
The technical problem to be solved by the utility model is to reduce because travel switch damage caused by accident, avoid work
In insecurity factor, it is ensured that equipment operate normally.
The technical scheme adopted by the utility model is overhead traveling crane lifting mechanism extreme position special alarming device, overhead traveling crane is risen
It rises mechanism (2) electric signal connection hand control switch (1) and electromagnetic switch (3), the stroke being mounted on overhead traveling crane lifting mechanism is opened
(5) electric signal connection electromagnetic switch (3) is closed, displacement sensor (4) the electric signal connection electromagnetism being mounted on overhead traveling crane lifting mechanism
Switch (3) and warning device (6).
As a kind of preferred embodiment: hand control switch (1) and warning device (6) are mounted on overhead traveling crane lifting mechanism (2)
In drivers' cab.
The beneficial effects of the utility model are: lifting mechanism caused by reducing because of travel switch damage does not stop making steel wire
The equipment such as rope, suspension hook.It ensures that operation, the stopped process of overhead traveling crane are steady, brakes relatively reliable.It ensure that the accuracy of operation,
When suspension hook is close to extreme position, alarm device can sound an alarm prompt operator and controller is withdrawn zero-bit in time, and realization is worked as
The demand of the present work production, that is, require operator steady, quasi-, fast, safety, it is reasonable require, improve equipment running rate and
Working efficiency.Reduce the working strength and degree of fatigue of operator, when operation can more concentrate one's energy, and ensure operation rule
Model, standard, efficiently, significantly reduce the security risk of operation process, for safe operation improve sound assurance.
Detailed description of the invention
Fig. 1 is the circuit connection diagram of the utility model；
Wherein, 1, hand control switch, 2, overhead traveling crane lifting mechanism, 3, electromagnetic switch, 4, displacement sensor, 5, stroke opens
It closes, 6, warning device.
Specific embodiment
As shown in Figure 1, the utility model is a kind of improvement to existing overhead traveling crane lifting mechanism extreme position control circuit,
In development, on overhead traveling crane install one for detect lift hook position displacement sensor 4 and one when lift hook position connects
Realtime Alerts dress when alert locations (specific location, which can be set such as, can be 1 meter of distance limits position) of proximal pole extreme position
6 are set, when lift hook position reaches the distance that alert locations start casting lift hook position real-time range extreme position, prompting driver's note
Meaning, 4 electric signal of simultaneous displacement sensor connect electromagnetic switch, and overhead traveling crane lifting mechanism is controlled when lift hook position reaches capacity position
2 stop, and the utility model realizes that overhead traveling crane lifting mechanism 2 stops by displacement sensor 4 and 5 dual fail-safe of original travel switch,
Safety stop can be realized by having any one damage occur, in addition both damaged in time, can also be passed through the hand of driver
The stopping of overhead traveling crane lifting mechanism is realized in dynamic control, ensure that the safe and stable operation of overhead traveling crane lifting mechanism 2.
