Abstract
A remote control system for the container hanger without electric cable is composed of hanger set and the driver cab of bridge crane. Said hanger set has the remote control emitter for emitting the limit signals. Said drive cab has a remote control receiver for receiving said limit signals for driving different electromagnetic valves of hanger set.
Description
This case is that application number is: 01113425.9 divide an application.
Technical field
The present invention relates to container handling machinery, particularly a kind of command and control system of hanger without electric cable.
Background technology
One more than 60 meter long suspender cable all is housed between suspender on the existing container handling machinery and the machine tool, is used for the power and the signal transmission of each action of suspender.Suspender hoists, descends when loading and unloading operation, and the suspender cable is stored effectively by cable storage frame or tension cable reel.Owing to hoist with little vehicle speed constantly increases and when running into strong wind in the course of the work, the suspender cable is cisco unity malfunction usually, cable takes place when particularly adopting cable storage frame frame even hooked to break, and causes hoisting crane to shut down.On certain meaning, can the suspender cable normal operation be the key that can hoisting crane all weather operation.Moreover the vertical cable of suspender is worth expensive, if be damaged, changing vertical cable must increase expense.
If change the folding and unfolding that realizes cable by the suspender cable drum into, then on the dolly of hoisting crane, increase by a cover complicated mechanical electric apparatus, make dolly layout trouble, manufacturing cost increases.
Common container spreader generally overlaps hydraulic power station as propulsion source by a direct motor drive one, and electrical motor is generally 7.5kW, for to its power supply, the suspender cable must be housed, and the shortcoming of bringing thus also is unavoidable.
Summary of the invention
Task of the present invention provides a kind of command and control system of hanger without electric cable, and it has solved the technical matters of the signal transmission between hanger without electric cable and the crane driver, makes that the signal transmission between suspender and the hoisting crane realizes with remote control mode.
Technical scheme of the present invention is as follows:
A kind of command and control system of hanger without electric cable, it comprises hanger structure and bridge crane driver's cab, on the described hanger structure remote control transmitter is housed, described bridge crane driver's cab is equipped with receiver of remote-control sytem, the frequency of projector is identical with the frequency of receptor, after limit signal on the hanger structure inserts projector, radio wave band by fixed frequency sends, receptor by same frequency receives, convert the switching value signal to and drive specific electromagnetic valve intermediate relay, final each electromagnetic valve that drives suspender is realized the suspender run action.
The command and control system of hanger without electric cable of the present invention adopts remote control transmitter and receiver of remote-control sytem under the situation of cancellation suspender cable, have more the reliability and the convenience of practical application; By the transmission of the signal between hanger without electric cable and the crane driver, with remote control mode remote control and driving suspender.
Description of drawings
Fig. 1 is the remote control transmitter structural representation of a kind of hanger without electric cable command and control system of the present invention.
Fig. 2 is the receiver of remote-control sytem structural representation of a kind of hanger without electric cable command and control system of the present invention.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of command and control system of hanger without electric cable comprises hanger structure 1 and bridge crane driver's cab, on suspender is put 2 support 10 on the shelf remote control equipment (RCE) projector 101 is housed, and at the bridge crane driver's cab remote control equipment (RCE) receptor 102 is housed.Projector 101 sends signal to receptor 102, realizes the transmission up and down of bridge crane driver's cab signal and suspender signal.These signals comprise the control and the feedback signal of everything on the suspender, and pressure state signal and voltage state signal in the energy-storage hydraulic system, have realized that intelligently the hydraulic efficiency pressure system high pressure generates electricity automatically and the functions such as auto alarm of low voltage low oil pressure.
The frequency of projector is identical with the frequency of receptor, after limit signal on the hanger structure inserts projector, radio wave band by fixed frequency sends, receptor by same frequency receives, convert the switching value signal to and drive specific electromagnetic valve intermediate relay, final each electromagnetic valve that drives suspender is realized the suspender run action.
The concrete configuration of remote control equipment (RCE) is as follows:
At the bridge crane driver's cab FSE716 type receptor is installed, is received, output to the indicator lamp on PLC intelligent object and the control desk from the various limit signals on the suspender (comprising that suspender opens and closes lock signal, ejector pin signal, 20 feet and 40 feet signals etc.).A FSS716F type projector is installed in addition, the various control commands on the control desk (comprise and open and close lock order, the flexible order of suspender, guide plate action command etc.) are transmitted on the suspender.
A FSS716F type projector is installed on suspender is put on the shelf, and frequency is identical with the receptor frequency of driver's cab.All suspenders and put on the shelf on limit signal insert this projector after, the radio wave band by fixed frequency sends, and is received by the receptor of driver's cab same frequency, converts concrete switching value signal to.Equally, the receptor on suspender is put on the shelf receives the radio wave band that the driver's cab projector sends, and converts the switching value signal to and drives specific electromagnetic valve intermediate relay, finally drives each electromagnetic valve of suspender, realizes the suspender action.
The rubber buffer 103 of cushioning effect has been housed respectively on the support of remote control transmitter 101 and receiver of remote-control sytem 102.The steel rope energy disperser 104 of cushioning effect has been housed respectively on the support of remote control transmitter 101 and receiver of remote-control sytem 102.These shock absorption devices are installed, can be protected remote control equipment (RCE) to avoid the fierce impact in suspender when work and cause damaging, played the effect of quakeproof and quake-resistant.
Claims (3)
1. the command and control system of a hanger without electric cable, it comprises hanger structure and bridge crane driver's cab, it is characterized in that, on the described hanger structure remote control transmitter is housed, described bridge crane driver's cab is equipped with receiver of remote-control sytem, the frequency of projector is identical with the frequency of receptor, after limit signal on the hanger structure inserts projector, radio wave band by fixed frequency sends, receptor by same frequency receives, convert the switching value signal to and drive specific electromagnetic valve intermediate relay, finally drive each electromagnetic valve of suspender, realize the suspender run action.
2. the command and control system of hanger without electric cable according to claim 1 is characterized in that, the rubber buffer of cushioning effect has been housed respectively on described remote control transmitter and the receiver of remote-control sytem.
