Description
Technical field
The utility model relates to the one-touch telescopic control device of a kind of hoisting crane.
Background technology
The telescoping mechanism structural shape of the crane arm of hoisting crane is widely adopted at present mainly contains two kinds of patterns: telescopic hydraulic cylinder adds rope row's formula and single cylinder bolt-type.The former can only be used for the following hoisting crane of 5 joint arm joints; The latter is suitable for and the above hoister in large tonnage of 5 joint arms.Can the single cylinder bolt-type stretch mode realize it being the gordian technique of restriction China single oil cylinder hoisting crane development.The flexible prosecutor formula of single-cylinder plug type telescopic jib crane all is to follow Liebherr's control style at present: after setting flexible purpose state, the operator is under the prompting of display interfaces, repeatedly pull flexible bar handle to correct direction, single step, finish the expanding-contracting action of arm intermittently, this operating mode needs multi-pass operation, and inconvenience is arranged more.
The utility model content
The above-mentioned technical matters that exists for the extension and contraction control mode that solves existing single-cylinder plug type telescopic jib crane, the utility model provides a kind of hoisting crane simple in structure one-touch telescopic control device, the utility model only need be pulled a switch, and the expanding-contracting action of crane arm can be finished automatically continuously.
The technical scheme that the utility model solves the problems of the technologies described above is: the one-touch telescopic control device of a kind of hoisting crane, comprise flexible automatic switch, comprise flexible hand switch, arm pin force switch, cylinder pin force switch, telltale, electronic control unit, bolt mechanism state-detection switch, detector switch induction installation, hoisting arm expansion oil cylinder device for detecting length, hydraulic valve, described flexible automatic switch, flexible hand switch, arm pin force switch, cylinder pin force switch, telltale are installed in the control cabin; Bolt mechanism state-detection switch is installed on the bolt mechanism, the detector switch induction installation is installed in every joint arm afterbody, and flexible automatic switch, arm pin force switch, cylinder pin force switch, telltale, detector switch induction installation, hoisting arm expansion oil cylinder device for detecting length, hydraulic valve link to each other with electronic control unit respectively.
Above-mentioned hoisting crane also comprises flexible hand switch with in the one-touch telescopic control device, and flexible hand switch links to each other with electronic control unit.
Technique effect of the present utility model is: the automatic extension and contraction control technology of single cylinder single oil cylinder is the gordian technique of crane-car to the single oil cylinder development, is the problem of forefront in the industry.The utility model of this device has broken through the mode of the man-machine interactive of original complexity, for the single cylinder bolt-type extension and contraction control of single oil cylinder hoisting crane is sought a kind of mode easy and simple to handle, safe in utilization.Designed, set up a kind of advanced person's of standard control system mould simultaneously for enterprise
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises hoisting arm expansion oil cylinder device for detecting length 1, flexible hand switch 2, flexible automatic switch 3, arm pin force switch 4, cylinder pin force switch 5, a plurality of bolt mechanism state-detection switch 6, electronic control unit 7, a plurality of bolt mechanism status indicator lamp 8, hydraulic valve 9, telltale 10, CAN bus 11, and described flexible automatic switch 3, arm pin force switch 4, cylinder pin force switch 5, telltale 10 are installed in the control cabin; A plurality of bolt mechanism state-detection switches 6 are installed on the bolt mechanism, and the detector switch induction installation is installed in every joint arm afterbody.
Behind the purpose state that sets hoisting arm expansion on the telltale 10, flexible automatically interface can appear in telltale.At this moment pull flexible automatic switch 3, make it closed, electronic control unit 7 (PLC Programmable Logic Controller) starts the intelligent decision algorithm, and go out bolt mechanism according to the calculated signals of telescopic oil cylinder linear transducer and where save inside the arm, and the existing condition of cylinder pin, arm pin.And then after the current state of arm (last expanding-contracting action finish back preserve) and purpose state compared, draw bolt mechanism, telescopic oil cylinder will be the sequence of operation table of purpose state with hoisting arm expansion, according to this sequence of operation modulated pressure valve 9, realize the flexible automatically of arm, up to being the purpose state with hoisting arm expansion.Simultaneously, electronic control unit 7 (PLC Programmable Logic Controller) is sent to telltale 10 with the information that it receives by CAN bus 11, moves animation program on telltale, the state of Real time dynamic display arm, bolt mechanism.As Redundancy Design, on the instrument desk of control cabin, also design bolt mechanism status indicator lamp 8, the state of indication bolt mechanism.
The groundwork principle of single cylinder bolt-type telescoping mechanism is as follows:
Be furnished with a telescopic oil cylinder in the arm.The telescopic oil cylinder header arrangement has telescoping mechanism.Be furnished with cylinder pin and bolt mechanism on the telescoping mechanism.Every joint arm has one or two arm pin-and-hole respectively at 0%, 46%, 90%, 100% length direction, and two sides of tail then respectively has two cylinder pin-and-holes, and there is an arm pin afterbody top, is used for the locking between arm and the arm.During telescoping boom, telescopic oil cylinder drives bolt mechanism and finds the telescopic boom N afterbody that will stretch, and stretches out the cylinder pin with telescopic oil cylinder and telescopic boom N locking, and withdrawal is inserted in the arm pin among the arm N-1.Stretch (contracting) telescopic oil cylinder, telescopic boom N and then stretches (contracting), and behind the arrival telescopic location, bolt mechanism release arm pin with telescopic boom N and telescopic boom N-1 locking, is finished the expanding-contracting action of telescopic boom N.Finish the flexible of each joint telescopic boom and so forth in fact, thereby finish whole expanding-contracting action
The utility model of this device is that the extension and contraction control of single cylinder bolt-type hoisting crane has been sought a kind of controlling party easy and simple to handle, safe in utilization.The operator makes it closed as long as easily pull a flexible automatic switch, electronic control unit just can rely on rich sensor information, carries out the intelligent decision control policy, carry out computing, the modulated pressure valve member opens and closes, openings of sizes, and arm is stretched into the purpose state that the operator is provided with automatically.Automatically the real-time status that dynamically shows arm, arm pin telescoping boom the time on the telltale.Except stretching automatically, this device has also designed manual stretch mode.Realize by being used in combination flexible hand switch, arm pin force switch, cylinder pin force switch.
