Abstract
The invention provides an automatic synchronous bottom oil cylinder jacking and lowering device of a crawling crane. The device comprises a control box in which a manual operating module and an automatic operating module are arranged; a solenoid directional valve is mounted on an oil line of an oil cylinder of the bottom of the crawling crane; a vehicle body horizontal sensor is mounted at the telescopic end of the bottom oil cylinder; the manual operating module is directly connected with the solenoid directional valve to control the bottom oil cylinder to be raised and lowered; the automatic operating module is synchronously connected with the solenoid directional valve and the vehicle body horizontal sensor and is automatically controlled by receiving a signal from the vehicle body horizontal sensor. The automatic synchronous bottom oil cylinder jacking and lowering device of the crawling crane is simple in structure; the degree of manual intervention from an operator can be reduced, so that the degree of fatigue of the operator in operation can be decreased, the automation degree of the operation can be increased, and the safety of the bottom of the crawling crane in raising and lowering can be improved.
Description
Technical field
The present invention relates to hydraulic lift technical field, be specifically related to oil cylinder automatic synchronization jacking lowering means bottom a kind of crawler crane.
Background technology
Bottom existing hoisting crane when dismounting and installation, traditional is employing four hydraulic actuating cylinder jackings and decline, and what have controls with solenoid directional control valve, and what have controls with hand change over valve.There is four cylinders jacking and decline function together, also have the holding function of an independent cylinder.
Problems existing is: be generally Hydraulic Pump fuel feeding, together an action, and parallel connection exists the inconsistent phenomenon of each branch circuit load pressure, and what pressure was little will first move and dynamic fast, large dynamic and dynamic after the meeting slow of pressure; If the series connection of each cylinder oil circuit, there is the problem of pressure superposition, system pressure higher, require that the withstand voltage of each Hydraulic Elements improves.
In jacking decline process, be all carry out artificial operation adjustment by driver to come bottom leveling now, driver's manual intervention degree is large, and easily tired, operation mistake also easily causes main frame to tumble.
Summary of the invention
Technical matters to be solved by this invention is the deficiency for above-mentioned existence, there is provided a kind of structure simple, reduce driver's manual intervention degree, alleviate the degree of fatigue of driver operation, strengthen the degree of automation of operation, oil cylinder automatic synchronization jacking lowering means bottom the crawler crane of the safety of jacking decline operation bottom raising hoisting crane.
The technical solution adopted for the present invention to solve the technical problems is:
Oil cylinder automatic synchronization jacking lowering means bottom crawler crane, is characterized in that: include a control capsule, is provided with M/C module and automatic operation module in control capsule; Bottom hoisting crane oil cylinder oil circuit on solenoid directional control valve is installed, and at the telescopic end of bottom oil cylinder, car body horizon sensor is also installed; Wherein, described M/C module directly connects solenoid directional control valve, carries out bottom oil cylinder elevating control; Described automatic operation module connects solenoid directional control valve and car body horizon sensor simultaneously, and the signal received from car body horizon sensor controls automatically.
In such scheme, described solenoid directional control valve has multiple, and correspondence is arranged on the oil circuit of multiple bottoms oil cylinder respectively.
In such scheme, described automatic operation module includes PLC, and PLC is parallel with multiple solenoid directional control valve, and can send control command to each solenoid directional control valve respectively.
In such scheme, described M/C module includes manual mode controller, and manual mode controller is also parallel with multiple solenoid directional control valve, and can send control command to each solenoid directional control valve respectively.
In such scheme, be line traffic control or remote control mode between described control capsule and solenoid directional control valve.
Principle of the present invention is: the control capsule of line traffic control or remote control has two operation modes, an automatic mode, a manual mode.Automatic mode is exactly that driver sends instruction by the PLC of control capsule, PLC receives the signal detected by the horizon sensor be arranged on car body simultaneously, PLC judges which solenoid directional control valve to send power on/off signal to by setup program, the signal intensity of car body horizon sensor is caused again after cylinder action, variation tendency is that the declarative instruction that error is reduced is correct, can continue action; Variation tendency is the declarative instruction mistake that error is increased, and needs to change instruction.Manual mode bypasses PLC exactly, directly sends power on/off signal to solenoid directional control valve, uses for scene adjustment.
Under automatic mode, PLC, except receiving the instruction of the rise and fall of control capsule, also will receive the detection signal that horizon sensor transmits, and then PLC inside is judged by stored Procedure, should give which or which solenoid directional control valve power on/off; The power on/off of electromagnetic valve can affect the stroke of oil cylinder, and the change of oil cylinder stroke can affect again the signal intensity of horizon sensor.The variable quantity of horizon sensor is input to PLC again, helps PLC to make and revises judgement.
The beneficial effect that the present invention produces is:
Invention compared with prior art has following main advantage:
Structure is simple, can reduce driver's manual intervention degree, alleviate the degree of fatigue of driver operation, strengthens the degree of automation of operation, improves the safety of jacking decline operation bottom hoisting crane.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention integral structure block diagram.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated:
