The technical scheme that the utility model is total, drive the revolution module of tower machine to be turned round by wireless remote controller is set, and realized the operation of electromechanical integration, makes the operator can break away from the driver's cab on the tower machine.Wherein wireless signal receiver and driver module are installed on the tower machine, and be connected with the rotating revolution module of control tower machine, the operator is by the wireless signal transmitter emissioning controling signal, after wireless signal receiver receives signal, by driver module, drive revolution module control tower machine to turn round operation.
Concrete, described wireless signal transmitter comprises load module, the processing module that transmits and transmitter module, and described signal processing module is connected with transmitter module with load module respectively.
Concrete, described load module is one or more in action button and operating handle, keyboard, touch-screen and voice input device.
The mode that adopts action button and operating handle to combine in this programme, advantage is to make the operator to simulate the operating mode in driver's cab, directly by the rocking bar control tower machine arranged on handle, similar with the control rocking bar in driver's cab, make the operator can adapt to faster remote control and control.
Concrete, the described processing module that transmits comprises coding unit, carrier modulation unit and the signal amplification unit connected successively.
Concrete, described transmitter module is emitting antenna.
Concrete, described wireless signal receiver comprises reception signal processing module and output circuit, described output circuit is connected with driver module with the reception signal processing module respectively.
Concrete, described reception signal processing module comprises signal amplification unit, demodulating unit, decoding unit and the driver element connected successively.
Concrete, also comprising electric protection module and drg, described electric protection module is connected with driving circuit, and described drg is connected with the revolution module with driving circuit respectively.
The purpose that the electric protection module is set is; when the tower machine possesses manual control and wireless remote control control simultaneously; can only allow at one time a kind of mode to be controlled the tower machine, avoid meeting accident, therefore need the electric protection module to carry out electric lock operation.
Concrete, described electric protection module is change-over swith.
The advantage that change-over swith is set is, after inside and outside change-over swith is installed, inside and outside control circuit board philosophy is controlled manually and remote control, and when change-over swith, during at interior location, the work of internal control circuit plate, can only realize M/C; When change-over swith, externally during position, the work of external control circuit plate, can only realize remote manipulation; And by controller, circuit is carried out to electrical interlocks, guarantee the safe in operation of hoisting crane.
Concrete, described wireless signal transmitter is provided with limit switch, starts module and alarm module.
The beneficial effects of the utility model are, have improved work efficiency, and operating personal can independent judgment, thereby accuracy, the continuity of operation were significantly improved than in the past; Be limited by pining down of upper and lower operator's compartment due to unnecessary, avoid the operator higher because of temperature in operator's compartment at high-temperature condition, uncomfortable and work efficiency that cause is not high, improved operating environment simultaneously, safety, reliability have been improved, and operating personal can be selected best angle, avoid poor visibility, with serious pollution operating position; Stop the operator and be subject to the infringement of pernicious gas, also owing to having saved commander's link, thereby avoided the improper misunderstanding caused due to commander; The operator can be in commander's angle operation, see clearly more intuitively by the article hoisting field condition, avoid in addition tower crane operation person insecurity in operator's compartment under inclement weather, and operator's aloft work and commanding officer link up wrong and cause unnecessary accident, also can realize that in the remote control situation people controls many tower machines.
The accompanying drawing explanation
The functional block diagram that Fig. 1 is wireless remote controller of the present utility model;
The control flow schematic diagram that Fig. 2 is embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail:
As shown in Figure 1, wireless remote controller for tower type crane slewing gear described in the utility model, comprise wireless signal transmitter, wireless signal receiver, driver module and revolution module, described wireless signal transmitter matches and is connected by wireless signal with wireless signal receiver, and described driver module is connected with the revolution module with wireless signal receiver respectively.The operator can realize the repertoire by manual drive tower machine operation person hands-operation by remote manipulation, can complete simultaneously swing type mechanism left, to the right, the location, the gearshift; Be specially: according to the actual needs of tower machine work, corresponding button in the push key circuit, produce thus one group of binary data code, under the control of the processing module that transmits, a string data code is sent to modulator circuit from cell encoder, digital signal is converted to the analog signal of transmitting on carrier current channel in modulator circuit.This analog signal enters transmission circuit via interface circuit, and goes out by transmission antennas transmit.The signal receiving processing module enters demodulator circuit via acceptor circuit and interface circuit after receiving the next carrier signal of Digiplex emission.Demodulation is contrary with modulation, recovers data code from carrier wave.Data code after demodulation is sent into decoder circuit, demoder will be understood correct code signal and deliver to decoder circuit, drive corresponding relay work by driver module after decoder for decoding, thereby control tower machine revolution module is turned round, and has just completed thus button remote control tower machine and has carried out work.
Embodiment:
