In order to solve the problems of little remote control signals, little travel distance and easy misoperation of the existing remote control tower crane, the utility model comprises a button or a remote bar worktable, a digital coding launching system, a receipt decoding system, a multi-channel amplifying output system, a relay interface and a control box, a power mechanism of the tower crane and an interphone. The device is characterized in that every channel of signal output from the multi-channel amplifying output system respectively controls every relay of the relay interface circuit and a time relay is arranged at the same time, thus error operation can be prevented. By adopting the anti-misoperation device, the high intensity aerial operation can be solved and aerial environment is avoided, thus no accident occurs.
Description
Technical field:
Belong to the weight-lifting equipment class, be specifically related to tower crane digital radio remote tracking error-proof device.
Background technology:
Current field of remote control kind has multiple, as infrared light remote control, the remote control of radio analog signal, intercommunication remote control etc., in the various light composition of construction site complexity, the infrared light remote control is disturbed easily, radio analog signal anti-interference resistance especially is poor, the analog signal remote control is subjected to various electromagnetic interferences serious at construction site, and functional reliability is very poor, and is dangerous.The intercommunication remote control does not have the real high-altitude manual working of tower machine that realizes banning yet.Have performance such as extra-code remote controller reliable relatively in addition, still, the remote control shelves are few, and the remote controller double speed key stroke that perhaps has is very little, and maloperation takes place easily, makes the tower machine high-speed operation directly occur, and safety is affected.
Summary of the invention:
The purpose of this utility model: in view of the various hostile environment conditions of camp site, in order more reliably tower crane to be realized the ground remote control operation, thoroughly realize banning the manual aloft work of tower machine, eliminate the operation blind area simultaneously, omnidirectional tracking monitors, at any time intercommunication contact, and some maloperation situation of easily sending out of solution remote controller.
The technical solution of the utility model is: tower crane digital radio remote tracking error-proof device comprises button or distant bar operator's station, digital coding emission coefficient, reception decode system, multichannel amplification output system, relay interface and electric cabinet, tower crane actuating unit and interphone composition, it is characterized in that described multichannel amplify each road signal of exporting in the output system respectively each relay of direct control relay interface circuit also be provided with time relay simultaneously, can prevent bit error ratio operation.The technical solution of the utility model also further comprises omnibearing monitor system in forming, and it is made up of the camera of a device on the tower crane turntable and the monitoring device that is arranged on many cameras of non-blind area on the camp site and be arranged in the operation room.
The utility model has the advantages that: the tower machine adopts this digital radio telecommand to follow the tracks of highly intensive labour and the bad high altitude environment of disengaging that error-proof device can reach thorough solution aloft work, can guarantee the safe and reliable tower machine that uses efficiently again, can monitor intuitively and remote manipulation tower machine in operation room that error-proof device makes accident rate drop to zero.
Description of drawings:
Fig. 1 is that the utility model is formed scheme drawing,
Fig. 2 is a relay interface circuit theory scheme drawing.
Among Fig. 1, the 1st, button or distant bar operator's station, the 2nd, the digital coding emission coefficient, the 3rd, receive decode system, the 4th, multichannel is amplified output system, the 5th, relay interface and electric cabinet, the 6th, tower crane actuating unit, the 7th, interphone, the 8th, omnibearing monitor system.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model specific embodiment is elaborated.Referring to Fig. 1, tower crane digital radio remote tracking error-proof device, comprise button or remote-control lever operator's station (1), digital coding emission coefficient (2) receives decode system (3), multichannel is amplified output system (4), relay interface and electric cabinet (5), tower crane actuating unit (6), interphone (7) is formed, wherein multichannel is amplified each road signal of exporting in the output system and also is provided with time relay each relay of direct control relay interface circuit the time respectively, prevents maloperation.Also comprise omnibearing monitor system (8) in composition, it is made up of the camera of a device on the tower crane turntable and a plurality of cameras that are arranged on non-blind area on the camp site and the high LCD monitor that is arranged in the operation room.Wherein digital coding emission coefficient (2) is made of rf carrier, digital coding circuit, radio transmitter circuit; Receiving decode system (3) is made of radio reception, digital decoding circuit; Multichannel is amplified output system (4) and is made of amplification promotion circuit, relay output circuit; Relay interface and electric cabinet (5) are made of relay interface circuit and electric control box.
The groundwork of tower crane digital radio remote tracking error-proof device is: produce a high frequency wireless carrier by radio-frequency generator, modulate through the multiple digital signal of digital coding circuit establishment seniority top digit, launch extraordinary radio modulation ripple by transmission circuit again, constituted the digital coding emission coefficient, after this radiowave is received by cooresponding radio receiver, restore original various digital signals through the decoding of internal digital decoding circuit, by amplifying and output, remove to promote the multiplex output circuit of several roads to tens tunnel by designer's intention, organically combine by relay interface and chain circuit and electric-control system again, go to each mechanism of remote manipulation tower crane, allow whole tower machine become taming instrument.Need install camera in all angles at the scene, carry out picket surveillance, add the intercommunication commander, operator, supplier, demanding party and field condition are linked together closely by monitoring device.Referring to Fig. 2, in conjunction with relay interface circuit principle schematic, further specify as follows: each relay that amplifies each road signal difference direct control relay interface circuit of output system (4) output by multichannel, as the 1 road signal control relay J closure, J then controls the general supply contactless switch adhesive of electric control box (5) and send, the 2 the tunnel, the 3 road signal is waited until then control relay J1 respectively of 18 road signals, J2, J3 ... J17, J1～J17 relay respectively the rising 1 of control tower machine fast 2 fast 3 speed; Descend 1 fast 2 fast 3 speed, revolution left and 1 speed to the right, 2 speed, 3 speed, 4 speed, luffing forward and 1 speed and 2 speed backward, and compatible electric bell, brake and signal etc.For anti-misoperation, be provided with time relay KT
1～KT
17, as 1 speed direct maloperation to 2 speed that hoists, by KT
1Finish that 1 speed rises earlier after 2 speed could cycling starts behind the delay time of setting, KT
2Be to establish to the transition of 3 speed for finishing 1 speed, 2 speed will be by KT to 3 speed
2Transition in the time of setting, otherwise with restricted; KT
3Be the direct high speed cycling start of restriction, as the straight then KT of three speed that rises
3To directly it be transferred to 1 speed, inaccurate 3 speed start.Through this cover system the mandatory requirement operator is operated in operation sequence, can reach fool proof purpose.
