Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of not making creative work, all should belong to present invention protection
Scope.
It is more than the core concept of the present invention, in order that those skilled in the art more fully understand the present invention program, under
Face combines accompanying drawing, and the present invention is described in further detail.
The scheme of installation of the wheel detection device that Fig. 1 provides for the embodiment of the present application.
As shown in figure 1, in figure 100 is sintering pallet；200 is trolley wheel, and 300 is the track of pallet.This vehicle
Detection means is installed in rail 300, as shown in figure 1, being provided with the detection breach of a depression on the working face of in rail 300
400, when running in wheel 200 in rail 300, wheel can be hanging at detection breach 400.Alternatively, another reality of the present invention
Apply in example, the working face of track is disconnected by detection breach 400, such wheel can be completely hanging at detection breach 400.
In order to improve accuracy, in other embodiments, described track is also provided with multiple detection breach, each
It is provided with a set of described wheel detection device in detection breach.
The structural representation of the vehicle detection apparatus that Fig. 2 provides for the embodiment of the present application.In conjunction with shown in Fig. 1 and Fig. 2, this car
Detection means includes：Proximity test switch 1, power supply 2, relay and alarm 4, wherein, proximity test switch 1 is located at detection
In breach 400；First connection terminal of proximity test switch 1 is electrically connected with power supply 2；Second connection end of proximity test switch 1
Son is electrically connected with one end of the control coil 31 of relay；The other end of control coil 31 of relay 3 is electrically connected with power supply 2；
Alarm 4 is electrically connected with power supply 2 by the contact 32 of relay, and described relay contact 32 can control power supply 2 to alarm 4
Power supply, for example：The contact 32 of relay is normally opened contact, when the coil 31 of relay is energized, can be by the contact 32 of relay
Adhesive is so that power supply 2 is powered to alarm 4.
As shown in figure 1, proximity test switch 1 is located in detection breach 400, and proximity test switch 1 is apart from track 300
Top surface between be provided with certain distance, normal wheel when by detecting breach 400, the lower edge of wheel will not with close to inspection
Slowdown monitoring switch 1 contacts, and will not trigger proximity test switch, but if damaging occurs in the bearing of wheel, then wheel is through inspection
When surveying breach 400, it will move down than normal wheel, this will encounter proximity test switch, and that is, triggering proximity test is opened
Close.
Power supply 2 can be common power, for example：Dc source or AC power, in embodiments of the present invention, with alternating current
As a example source.
Proximity test switch 1, the coil 31 of relay are in series, and the circuit two ends after connecting respectively with power supply 2
Both positive and negative polarity is connected.The contact of proximity test switch 1 is normally opened contact, when proximity test switch 1 is subject to wheel touch trigger, connects
Nearly detection switch 1 will close, so the coil 31 of relay switch on power after be energized.
Alarm 4 is connected with power supply 2 by the contact of relay, and alternatively, the contact of relay has multigroup, and reports
Two connector lugs of alert device 4 are connected with the both positive and negative polarity of power supply 2 respectively by two groups of contacts respectively.
After the coil 31 of relay is energized, the contact 31 of relay will close, and then alarm 4 is switched on power,
Reported to the police.
The embodiment of the present application provide this device, due to wheel bearing prejudicial in the case of, when hanging, the wheel of damage
Lower edge can be lower than the lower edge of normal wheels, and then detection breach ought be provided with orbit, and arrange in detection breach
Proximity test switchs, and the vehicle that such bearing is damaged, will under gravity, to detection breach when through detection breach
Internal mobile, and then the proximity test switch 1 being arranged in detection breach is triggered, correspondingly make the coil of relay
Conduction, after the coil conduction of relay, with the closing of contact of motor type relay, finally makes alarm and power on, is reported
Alert, point out the bearing that staff has wheel to occur damaging, need to check in time and change, it is to avoid the wheel of damage moves to rail
Road corner leads to pallet card problem in orbit.
After alarm starts to report to the police, staff has already known that wheel is damaged, and can shut down sintering pallet,
This may result in the wheel continuous extrusion proximity test switch of damage, namely alarm can persistently be reported to the police, in staff existing
During the maintenance of field, alarm can interfere to staff.
After shutting down in order to avoid pallet, the wheel of damage makes alarm persistently report to the police, as shown in Fig. 2 in this Shen
Please be in embodiment, this device can also include：Hand brake switch 5.
The contact of hand brake switch is normally-closed contact, and hand brake switch is connected on described relay, proximity test is opened
Close in the loop forming with power supply.When staff needs manual stop alarm device work, can directly hand brake be opened
The contact closed is opened, so that the coil blackout of relay, and then the contact of relay is opened, by between alarm and power supply
Connection disconnect.
When power supply is for AC power, in order to improve the security after power-off it is preferable that hand brake switch is connected on friendship
Between first connection terminal of the hot terminal of stream power supply and proximity test switch, the coil of relay is switched with proximity test
The second connection terminal be connected.So after hand brake switches off, the coil of relay will not directly and AC power
Hot terminal be connected, reduce potential safety hazard.
In addition, the security of the coil in order to improve relay, as shown in Fig. 2 this device can also include：Relay is protected
Shield switch 6.
Relay protection switch 6 is in parallel with proximity test switch.Relay protection switch 6 and proximity test switch 1
Linked switch, that is, during proximity test switch 1 closure, relay protection switch 6 also closes；Proximity test switch 1 is opened, relay
Protection switch 6 is also opened.
When electric current is larger, relay protection switch 6 disconnects automatically, correspondingly also drives proximity test switch 1 disconnection, keeps away
Exempt from high current the coil of relay to be caused damage.
When power supply is for AC power, in this application, a connection terminal of described alarm passes through described relay
One group of contact electrically connect with the hot terminal of described AC power；Another connection terminal of described alarm passes through described
Another group of contact of relay is electrically connected with the zero line terminals of described AC power.
In addition, in order to improve security, no matter it is can also to set between alarm or relay coil, and AC power
Put breaker, circuit is protected.
In this application, alarm is connected with AC power using same breaker with the coil of relay.As Fig. 3 institute
Show, in figure breaker is 7.L is hot terminal, and N is zero line terminals.
All contacts of described alarm and described relay form the first loop, and described first loop is by described open circuit
Device is connected with described power supply；
The coil of described proximity test switch and relay forms second servo loop, or, described proximity test switch, relay
The coil of device, hand brake switch composition second servo loop；Described second servo loop is connected with described power supply by described breaker.
In the application other embodiments, alarm is voice guard, such as sound equipment；Or, described alarm is lamp
Light crossing-signal, for example：Bulb, or, described alarm is audible-visual annunciator.
