Description
Technical field
It the utility model is related to a kind of bridge crane fixed pulley steel cable slot disengaging warning device.
Background technology
Bridge crane（That is overhead traveling crane）It is the capital equipment for producing plant area's transported material in metallurgy industry, there is work frequency
It is numerous, load operating rate is high, fireballing feature.And operationally out of order probability is also larger for overhead traveling crane, overhead traveling crane failure will be serious
Influence the normal production order.Due to when violation operation or suspension hook, which decline, encounters article generation upward active force, having often resulted in
Heavy-duty machine fixed pulley steel cable slot disengaging phenomenon.Fixed pulley steel cable slot disengaging failing to find that to will result in steel wire rope improper in time
Excessive wear, or even rope-broken accident occurs, improves overhaul of the equipments cost and workload, cause greatly to pacify to normal production
Full hidden danger simultaneously brings unnecessary economic loss.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of bridge crane fixed pulley steel cable slot disengaging alarm
Device, the present apparatus provide alarm signal in time to steel cable slot disengaging, so that it is non-to have prevented the steel wire rope caused by steel cable slot disengaging
Normal excessive wear or rope-broken accident, it is ensured that the normal operation of crane, avoids security risk, reduces overhaul of the equipments cost and work
Measure.
In order to solve the above technical problems, the utility model bridge crane fixed pulley steel cable slot disengaging warning device includes machine
Frame, fixed pulley axis, stent, base, travel switch and limit pull rod, the support vertical are arranged on the rack and are located at respectively
The fixed pulley axis both ends, the base are arranged on the cantilever tip, and the travel switch is arranged on the base end face, the limit
Motion end, the lower horizontal that position pull rod top connects the travel switch are extended to above the fixed pulley axis, and the stroke is opened
The contact signal of pass is connected to overhead traveling crane machine controller.
Further, the limit pull rod is located at described for motion end, the galianconism of L-shaped and the long-armed connection travel switch
Above fixed pulley axis.
Further, the travel switch is equipped with normally-closed contact and is serially connected with the control of overhead traveling crane machine controller main circuit breaker
Circuit, when travel switch normally-closed contact is opened a way, overhead traveling crane machine controller main circuit breaker disconnects.
Since the utility model bridge crane fixed pulley steel cable slot disengaging warning device employs above-mentioned technical proposal, i.e.,
The present apparatus includes rack, fixed pulley axis, stent, base, travel switch and limit pull rod, and support vertical is arranged on rack and difference
Positioned at fixed pulley axis both ends, base is arranged on cantilever tip, and travel switch is arranged on base end face, and limit pull rod top connection stroke is opened
Motion end, the lower horizontal of pass are extended to above fixed pulley axis, and the contact signal of travel switch is connected to bridge crane control
Device.The present apparatus provides alarm signal in time to steel cable slot disengaging, so that it is non-just to have prevented the steel wire rope caused by steel cable slot disengaging
Normal excessive wear or rope-broken accident, it is ensured that the normal operation of crane, avoids security risk, reduces overhaul of the equipments cost and work
Amount.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the utility model bridge crane fixed pulley steel cable slot disengaging warning device structure diagram.
Embodiment
Embodiment is as shown in Figure 1, the utility model bridge crane fixed pulley steel cable slot disengaging warning device includes rack
1st, fixed pulley axis 2, stent 3, base 4, travel switch 5 and limit pull rod 6, the stent 3 are vertical at the rack 1 and divide
Not Wei Yu 2 both ends of fixed pulley axis, the base 4 is arranged on 3 top of stent, and the travel switch 5 is arranged on the base 4
End face, motion end, the lower horizontal that 6 top of limit pull rod connects the travel switch 5 are extended on the fixed pulley axis 2
Side, the contact signal of the travel switch 5 are connected to overhead traveling crane machine controller.
Preferably, the limit pull rod 6 is located at institute for motion end, the galianconism of L-shaped and the long-armed connection travel switch 5
State the top of fixed pulley axis 2.
Preferably, the travel switch 5 is equipped with normally-closed contact and is serially connected with the control of overhead traveling crane machine controller main circuit breaker
Circuit processed, when 5 normally-closed contact of travel switch is opened a way, overhead traveling crane machine controller main circuit breaker disconnects.
The structure of present apparatus combination bridge crane, increases a safe spacing in the fixed pulley group both sides of bridge crane
Structure, it respectively installs a travel switch, the action of travel switch in bridge crane fixed pulley both sides by stent and base
Component extends downwardly a certain distance by limit pull rod, when fixed pulley steel cable slot disengaging falls, falls first in limit pull rod
Galianconism, while drive two travel switches to act by limit pull rod, its normally-closed contact disconnects after travel switch action, bridge-type
Crane stops running immediately and is in alarm condition.
Solve the problems, such as that steel cable slot disengaging cannot be found in time substantially using the present apparatus, so as to prevent because steel wire rope takes off
The improper excessive wear of steel wire rope caused by groove or rope-broken accident, provide safety assurance, really to bridge crane normal operation
The normal production order has been protected, has avoided security risk, has reduced overhaul of the equipments cost and workload.
