To keep the purposes, technical schemes and advantages of the utility model implementation clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Described reality
Applying example is the utility model a part of the embodiment, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and should not be understood as limiting the present invention.It is practical new based on this
Embodiment in type, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.The embodiments of the present invention are described in detail with reference to the accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of crane remote control early warning system, the early warning system include sound module 1, when
Between relay KT, remote controler 2, power supply 3；The sound module 1 is concatenated with the normally opened contact K1 phase in remote controler 2, by normally opened
The on-off of contact K1 realizes the start and stop of sound module 1；Delay break contact KT-1 in the time relay KT connects with multiple
Branch after the normally opened contact I of tentaculum concatenates is concatenated with normally opened contact K1 phase；Coil one end of the time relay KT and electricity
Source is connected, and the coil other end of time relay KT is connected to the normally opened contact I and delay break contact KT-1 of multiple contactors
Between route in；When starting lifting, each contactor movement is closed multiple normally opened contacts, and time relay KT obtains electrician
Make, while sound module 1 is alarmed, but because of delay break contact KT-1 of the string in 1 circuit of sound module because the time relay obtains
Electricity and be delayed after disconnect so that 1 power loss stop alarm of sound module.
The preferred embodiment in above-described embodiment about sound module is given below:
Sound module 1 uses electric bell.Certain sound module 1 is also possible to loudspeaker and buzzer etc..
With continued reference to shown in Fig. 1, Fig. 2, multiple contactors are respectively contactor KM2, contactor KM3, contactor KM4, connect
Tentaculum KM5, contactor KM6, contactor KM7；Wherein, contactor KM2, contactor KM3 coil tandem remote controler remote control
In contact, contactor KM2, contactor KM3 normally opened contact II be connected with motor M1, pass through control remote controler 2 in switch
The operation up and down of SB1, switch SB2 realization crane.
Contactor KM4, contactor KM5 coil tandem in the remote control contact of remote controler, contactor KM4, contactor KM5
Normally opened contact II be connected with motor M2, pass through control remote controler 2 in switch SB3, switch SB4 realization crane front and back fortune
Row.
Contactor KM6, contactor KM7 coil tandem in the remote control contact of remote controler, contactor KM6, contactor KM7
Normally opened contact II be connected with motor M3, pass through control remote controler 2 in switch SB5, switch SB6 realize crane control fortune
Row.
It should be noted that having transmitter and receiver in the remote controler 2, when pressing operation button on remote controler 2, send out
Emitter emits signal to receiver, and recipient makes its internal normally opened contact K1 closure after receiving signal processing, at this time sound module 1
Restore electric, starts jingle bell early warning.
Power supply 3 is control transformer KB, and the primary side side of control transformer KB is connected in 380V main power source, controls transformation
The secondary side of device KB is connected with early warning system.Control the model KB380/36V of transformer KB.
The model AT3P-AC36V of time relay KT.
It is remotely controlled the working principle of early warning system
1) automatic early-warning principle when equipment starts
2 electromagnetic safe lock of remote controler is placed on remote controler unlocked position, remote control is pressed in the unlock of 2 inside locking poiut of remote controler
Device " beginning/alarm bell " button (the operation button K i.e. in figure), main contactor KM1 is attracted in crane electric box, 380V main power source
Into the trolley electric cabinet on electric block, control transformer KB primary side is obtained electric in trolley electric cabinet, and secondary side exports 36v control
Voltage processed continues to press " beginning/alarm bell " button, remote control normally opened contact K1 closure at this time, while early warning electric bell L must be established by cable
Beginning jingle bell, unclamps and is somebody's turn to do " beginning/alarm bell " button, and jingle bell stops.
When starting lifting, the movement of each contactor makes each control normally opened contact I (normally opened contact KM2-4, normally opened touching i.e. in figure
Point KM3-4, normally opened contact KM4-4, normally opened contact KM5-4, normally opened contact KM6-4, normally opened contact KM7-4) closure, the time after
Electric appliance KT work once electrified, while early warning jingle bell, but the delay break contact KT-1 because going here and there in electric bell circuit is because of the time relay
It obtains electric and is disconnected after delay.Power loss stops jingle bell to early warning electric bell again.The secondary jingle bell is crane automatic early-warning jingle bell.When jingle bell
Between be delayed contact actuation time, can need to adjust according to different.
2) early warning principle in crane operational process
During crane carries out hoisting operation, operator will carry out early warning, can press remote controler " beginning/alarm bell " and press
Button, remote controler emits signal to signal receiver at this time, and recipient makes its internal normally opened electric shock K1 closure after receiving signal processing,
Electric bell L restores electric at this time, starts jingle bell early warning, and to terminate early warning, operator unclamps " beginning/alarm bell " pressed and presses
Button, signal receiver no longer receive signal, and internal normally opened electric shock K1 is voluntarily disconnected, and electric bell L power loss stops jingle bell, terminates early warning.
3) in hoisting operation, operator can press " beginning/alarm bell " button at any time and carry out early warning.It is easy to operate, it is sensitive
Reliably.
It follows that remote control operation of the early warning system by crane operator, is issued loud in time by electric bell
Pre-warning signal, avoid with cammander issue command signal interfere with each other, cause maloperation.The early warning system can be opened in equipment
It before dynamic, voluntarily issues warning signal, in equipment operation, when various hoisting operations movements start, the work of active forewarning circuit is carried out
Jingle bell early warning.Operator operates capable of also issuing warning signal whenever and wherever possible for remote control simultaneously, and slinging work is enable to carry out safely.
When there is other staff to enter operating area, operator sends alarm signal by pressing early warning button.Other people are reminded to infuse in time
Meaning safety, quickly avoids, it is ensured that hoisting operation securely and reliably carries out.
The utility model also provides a kind of crane comprising the remote control early warning system in the various embodiments described above, crane
Other parts be the prior art, not reinflated description herein.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of the utility model rather than limit it
System；Although the utility model has been described in detail with reference to the preferred embodiment, those of ordinary skill in the art should
Understand: specific implementation of the utility model can still be modified or is equally replaced to some technical characteristics
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
