Description
Technical field
The utility model belongs to autocrane field, and specifically a kind of Car Crane Retractable Arms band carries flexible protection control
System.
Background technology
It is to drive rope to realize arm by oil cylinder that medium and small tonnage Car Crane Retractable Arms are flexible in current Crane Industry
It is flexible.Because the load that oil cylinder and rope are carried is smaller, so forbidding operator to carry out arm while crane hangs load
Flexible operation.Simply regulation can not carry out band load scaling operation in operation instructions at present, in actual use
Operator often feels oneself to know a thing or two and violation operation, Car Crane Retractable Arms telescopic oil cylinder and rope unprotect, may
Cause the irreversible damage of Car Crane Retractable Arms telescopic system or even trigger serious accident.
Utility model content
The technical problems to be solved in the utility model is to overcome the defect of prior art there is provided a kind of Car Crane Retractable Arms
Band carries flexible Protection control system, can effectively be solved by this control system because violation operation, caused autocrane
The irreversible damage of hoisting arm expansion system or serious accident.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of Car Crane Retractable Arms
Band carries flexible Protection control system, including controller, arm displacement transducer, arm elevation sensor, pressure sensor, pressure
Switch, selecting switch and pilot solenoid valve, arm displacement transducer, arm elevation sensor and pressure sensor all with controller
Signal input part connect；Described pressure switch includes semi-girder pressure switch and contracting arm pressure switch, semi-girder pressure switch peace
On ground jack arm semi-girder hydraulic circuit, contracting arm pressure switch be arranged on contracting arm hydraulic circuit on, semi-girder pressure switch with
Contracting arm pressure switch is all connected with controller signals input；Selecting switch connects with the input of controller.
Controller is handled by the signal to arm displacement transducer, arm elevation sensor, pressure sensor, meter
Calculate the rated load value under current working, by Calculation and Analysis of Force go out oil cylinder and rope bear load limitation (be computed,
Bear load limitation for rated load 30%).The operating mode needed to use is selected by selecting switch again, switch default conditions are
Forbid band to carry scaling operation, press selecting switch and then the rated load value that is calculated according to controller, held when hanging load value and being less than
Band can be then carried out during the limit loaded and carries scaling operation.
Semi-girder pressure switch and contracting arm pressure switch transmit signals to controller, and current operator is judged by controller
Whether hoisting arm expansion operation can be carried out.
Controller output signal is to pilot solenoid valve under nominal situation, and pilot solenoid valve work can normal operating automobile crane
Machine.When autocrane, which is in, hangs load state, and judge that operator carries out hoisting arm expansion operation, with reference to selecting switch
State, judge whether to output signal to pilot solenoid valve by controller, pilot solenoid valve, which is powered, can carry out the operation of crane,
When pilot solenoid valve power-off, operation is also not carried out even if operator's operating control handle crane, reaches that arm suspending belt is carried flexible
The purpose of protection.
The input/output terminal of controller also connects with the input/output terminal of human-computer interaction device, can on human-computer interaction device
The signal exported according to controller displays whether that being in band carries flexible operating mode, points out operator to operate with caution.
Brief description of the drawings
Fig. 1 is the theory diagram that the utility model Car Crane Retractable Arms band carries flexible Protection control system.
Embodiment
In order to be more clearly understood that the utility model, with reference to the accompanying drawings and detailed description to the utility model
It is described further.
Car Crane Retractable Arms band carries flexible Protection control system, as shown in figure 1, including controller, arm displacement sensing
Device, arm elevation sensor, pressure sensor, pressure switch, selecting switch, pilot solenoid valve and human-computer interaction device, arm
Displacement transducer, arm elevation sensor and pressure sensor all connect with the signal input part of controller；Described pressure is opened
Pass includes semi-girder pressure switch and contracting arm pressure switch, and semi-girder pressure switch is arranged on ground jack arm semi-girder hydraulic circuit,
Contracting arm pressure switch is arranged on contracting arm hydraulic circuit, and semi-girder pressure switch and contracting arm pressure switch are all inputted with controller signals
End connection；Selecting switch connects with the input of controller；The output end of controller and pilot-actuated valve and human-computer interaction device
Connect.
Controller is handled by the signal to arm displacement transducer, arm elevation sensor, pressure sensor, meter
Calculate the rated load value under current working, by Calculation and Analysis of Force go out oil cylinder and rope bear load limitation (be computed,
Bear load limitation for rated load 30%).The operating mode needed to use, selecting switch acquiescence shape are selected by selecting switch again
State is forbids band to carry scaling operation, the rated load value pressed selecting switch and then calculated according to controller, and when hanging, load value is small
Band can be then carried out when load limitation is born and carries scaling operation, while display is currently to be in band to carry on human-computer interaction device
Flexible operating mode, points out operator to operate with caution.
Semi-girder pressure switch and contracting arm pressure switch transmit signals to controller, and current operator is judged by controller
Whether hoisting arm expansion operation can be carried out.
Controller output signal is to pilot solenoid valve under nominal situation, and pilot solenoid valve work can normal operating automobile crane
Machine.When autocrane, which is in, hangs load state, and judge that operator carries out hoisting arm expansion operation, with reference to selecting switch
State, judge whether to output signal to pilot solenoid valve by controller, pilot solenoid valve, which is powered, can carry out the operation of crane,
When pilot solenoid valve power-off, operation is also not carried out even if operator's operating control handle crane, reaches that arm suspending belt is carried flexible
The purpose of protection.
It is described above, only it is embodiment of the present utility model, is not limitation of the utility model, this area
Technical staff the change made using above-mentioned technology contents or is repaiied in the case where not departing from the utility model Technology design principle
Decorations, are regarded as belonging to protection domain of the present utility model.
