Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiment of the present invention high security crane;
In accompanying drawing, the mark of each parts is as follows: 1, base, and 2, column, 3, actuating unit, 4, control operation room, 5, remote control reception parts, 6, remote control transmitter, 7, equilibrium arm, 8, crane arm, 9, hang head.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the structural representation of embodiment of the present invention high security crane; This crane comprises base 1, column 2, actuating unit 3, control operation room 4, remote control reception parts 5, remote control transmitter 6, equilibrium arm 7, crane arm 8 and hangs 9, described column 2 is arranged on base 1, described control operation room 4 is positioned on column 2, it is outside and be connected with the control mechanism in control operation room 4 that described remote control reception parts 5 are arranged on control operation room 4, described equilibrium arm 7, a crane arm 8 and hang 9 and be positioned at column 2 top.
The high security crane that the present invention mentions is by combining the machinery of wireless remote control technology and overhead crane control mechanism, hydraulic pressure and electron controls technology, achieve the remote manipulation of crane and manual mode operation and use, and two kinds of operation interlockings also can switch easily, thus greatly improve processing safety and the operating efficiency of crane.
Control operation room 4 in this high security crane is provided with hand held console and control mechanism, and wherein, control mechanism is made up of signal processor, PLC primary controller and output driving circuit; Signal processor in this control mechanism is connected with the remote control reception parts 5 being arranged on outside, control operation room 4, and the corresponding signal of remote control reception parts 5 transmission can be processed, and transmit signal to PLC primary controller, send relevant execution instruction by the analysis of PLC primary controller, then send relevant drive signals by output driving circuit; Output driving circuit is connected with each parts in actuating unit 3, and driving associated components to complete predetermined action, each parts in this actuating unit 3 comprise jack up unit, turning gear, hang head moving device, cylinder efficient device, gear controller, steering controller and brake controller.The interference of the interference introduced by electrical network in order to avoid external disturbance and any surging, electrostatic, and command and control system is on the impact of manual control system, remote control reception parts 5 have employed anti-conducted interference power supply and high quality mu balanced circuit, meanwhile, have employed electromagnetic isolation plate between the control mechanism in itself and control operation room 4 and increase electrostatic screening.In order to ensure the accurate of transmission of wireless signals and continue reliable, the high gain that the remote control transmitter 6 of this high security crane configuration have employed that harmonic wave is less than 60dB, mounted modulating emission circuit is floated on power saving, stable surface and standing-wave ratio (SWR) is less than 1:2 corrects antenna, and four group storage batteries of its positioned inside can provide the continuous working voltage of half a year more than.
The remote control transmitter 6 of the high security crane configuration that the present invention proposes is made up of coder, modulation circuit, amplifying circuit and correction antenna, the various control command signals that remote controller inputs can carry out encoding by this remote control transmitter 6, carrier modulation and signal amplify, then launch with the form of radiowave by correcting antenna, then received by remote control reception parts 5.Wherein, remote control reception parts 5 are made up of amplifying circuit, decoding circuit, decoder and voltage-stabilized power supply circuit, the radio signal received carries out amplifying by these remote control reception parts, demodulation, the signal processor given in control mechanism processes after decoding, then PLC primary controller sends and performs instruction and output driving circuit and send relevant drive signals and drive corresponding actuating unit parts to complete predetermined action in control mechanism.In actual mechanical process, be in charging, the workmen of discharge position can be as required, signal is sent request to the operator holding remote controller by wireless interspeaker, after operator receives request signal, crane operated accordingly and control, having carried out the lifting carrying needs of each position.Like this, the not only accurate positioning of handling material, and also dangerous low, working strength also reduces much than traditional approach.Just in case occur that drop damage, electric energy of remote controller such as to exhaust at the malfunctioning situation of temporary remote control, also can enter and enable manual control mode in control operation room 4 and operate.
