The utility model has the advantages that the remote-distance remote-control operation control is realized, operators can get rid of the conventions of a traditional cab, the safety influence on the operators, caused by adverse factors such as high temperature, noise, dust, vibration, subsidence, unclear sight line and the like in the operation environment, can be reduced, and the optimum position can be freely selected for carrying out operation work on the digging machine.
Description
Technical field
The utility model relates to a kind of crawler-mounted excavator, relates in particular to a kind of circuit module of crawler-mounted excavator.
Background technology
The control of crawler-mounted excavator of the prior art mainly is that the staff finishes in driver's cabin.But abominable even have potential safety hazard or unhandy occasion at some operating environments, in driver's cabin, directly drive, control excavator by the staff and will cause a lot of dangerous or inconvenient factors to exist.
Production with mining industry in the hole, ore deposit is example, and the cardinal principle operation of hole, ore deposit mining is: leave the scope of operation-boring-explosion-excavator and dig mining stone-entrucking and transport in the hole, ore deposit.Because excavator digs the scope of operation of mining stone, is that the supporting protection facility can't be set, the uncertainty of the hole body plane of disruption during therefore along with extension of excavating and explosion, there is the danger of landslide in regular meeting in the excavation regions.
At the driving in-house operation of excavator, because the circumscribed restriction in the visual field, operating personnel can't in time recognize the situation of change on top, hole, excavator top, in case landslide occurs, operating personnel and excavator will face is pounded the hazardous situation that is buried, and is difficult to hide.Though at present protector has been installed additional in some enterprise on the excavator driver's cabin, also can only be limited avoid some to injure by a crashing object, for this foreseeable potential safety hazard, do not tackle the problem at its root.
Summary of the invention
The utility model technical issues that need to address have provided a kind of wireless remote control crawler-mounted excavator, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: remote-control transmitting module and remote control receiver module; Described remote control receiver module receives the signal of remote-control transmitting module and this signal is passed to middle electric appliance box; Electric appliance box connects respectively by hydraulic system in the middle of described, and electrohydraulic proportional control valve, each electric control point of the power of surging and the actuator that is provided by kinetic pump are provided.
Compared with prior art, the beneficial effects of the utility model are: realized Remote operation control, can make operating personnel break away from the constraint of traditional driver's cabin, alleviated high temperature, noise, dust in the operating environment, vibrated, subsided, security implication that unfavorable factor causes operating personnel such as sight line is unclear, can select best position to carry out operation task freely to excavator.
Description of drawings
Fig. 1 is the utility model module connection layout.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: remote-control transmitting module and remote control receiver module; Described remote control receiver module receives the signal of remote-control transmitting module and this signal is passed to middle electric appliance box; Electric appliance box connects electrohydraulic proportional control valve, each electric control point and actuator respectively in the middle of described;

Remote control launching system in the utility model is a remote control transmitter, is provided with on the remote control transmitter guidance panel that engine ignition control handle, grip, walking control rocking bar, knife plate are controlled distant bar, bucket is controlled action buttons such as distant bar, light switch, horn button, emergency stop switch.
Romote controlled receiving system is installed in the inside of described excavator.
Middle electric appliance box, electrohydraulic proportional control valve, each electric control point and actuator that the utility model adopts are prior art.
The remote control control principle of the utility model remote control excavator is: remote control transmitter is launched a radio signal, after receiver of remote-control sytem receives this signal, send the corresponding signal of telecommunication by middle electric appliance box, and pass to electrohydraulic proportional control valve, each electric control point and actuator, electrohydraulic proportional control valve and then control each function main valve, actuator and then control each functional circuit.
Electrohydraulic proportional control valve provides the power of surging by the system liquid pressing system.
Actuator provides the power of surging by kinetic pump.
The remote control of this remote control excavator has used radiotechnics, and operating procedure is as follows:
Operating personnel are a control stick or the button on the manual operation portable remote transmitter 3 at first, the portable remote transmitter converts manual command to a signal of telecommunication, transmitter is handled the back to this signal of telecommunication and is produced an Electronic Control instruction, transmitter passes to the antenna of transmitter after this instruction being carried out the detection of credibility and correctness.
The electromagnetic wave signal that sends by emitter antenna, different according to transmitted power, environment and weather condition, coverage can reach 100 meters to 150 meters.The electromagnetic wave signal that is sent by emitter antenna is received by the antenna of receiver in range of transmission, passes to computing module in the receiver by the antenna of receiver again.
Whether receiver can detect the electromagnetic wave that is received wrong; detect and convert them to Electronic Control instruction again after errorless; remove to control various ratio driver modules by middle electric appliance box; as: the acceleration of motor; the pass of hydraulic valve/open perhaps is used for controlling power-off protection apparatus and other electric installation.
The utility model remote control excavator comprises emission system, receiving system, middle electric system, hydraulic control and drive system, mechanical fixation and connected system.
Be provided with on the emission system guidance panel:
The igniting of ignition knob control engine start, flame-out control;
