Technical field
The present invention relates to crane descending supporting leg locking device.The invention still further relates to the method for using this device to control the supporting leg of getting off.
Background technology
Car hosit must launch the supporting leg of getting off when hoisting operation operating mode, and the action of control landing leg stretching is its inner cross cylinder and Vertical Cylinders.When hoisting crane during in lifting operating mode its supporting leg must carry out any action, cross cylinder and the Vertical Cylinders of controlling supporting leg all can not have expanding-contracting action, otherwise may cause that car load unstability causes overthrow accident.Whether the core component of the support operating device of getting off that in prior art, car hosit is used is the maneuvering valve of getting off, after complete machine work, no matter get on the bus and work, as long as handle the handle of getting off on maneuvering valve, support oil cylinder all can follow suit and move accordingly.If have personnel to remove to handle the maneuvering valve of getting off in hoisting crane hoisting operation engineering, just probably cause and car load unstability cause overthrow accident.There is poor stability, once the maneuvering valve maloperation meeting of getting off is caused to the technical matterss such as safety misadventure.
Summary of the invention
The problem to be solved in the present invention is to provide crane descending supporting leg locking device, and in the process of hoisting crane work, the whether locked descending valve of automatic decision, prevents the safety misadventure causing getting off faulty switching when crane job; For this reason, the present invention also provides the method for using this device to control the supporting leg of getting off.
For solving the problems of the technologies described above, the technical solution used in the present invention is: crane descending supporting leg locking device, comprise controller, the change-over switch of getting on or off the bus, guide's enable switch and the maneuvering valve of getting off, the described change-over switch of getting on or off the bus is electrically connected to described controller signals input end, described guide's enable switch is electrically connected to controller signals input end, described in the maneuvering valve of getting off be electrically connected to controller signals mouth.
Further, described in the maneuvering valve of getting off comprise guide's electromagnetic cartridge valve, described guide's electromagnetic cartridge valve is electrically connected to described controller signals mouth.
Further, described guide's electromagnetic cartridge valve is two-position three-way electromagnetic inserted valve.
For solving the problems of the technologies described above the control effect that reaches good, the present invention also provides the method for using this device to control supporting leg: when described controller detects guide's enable switch and is opening, to the maneuvering valve of getting off, send locked signal;
When described controller detects guide's enable switch in closed condition, controller can continue to detect gets on or off the bus change-over switch in for which working position, when controller detects the change-over switch of getting on or off the bus in upper parking stall, illustrate that now hoisting crane is in hoisting operation operating mode, controller sends locked signal; When controller detects it when getting off working position, car load is in the working condition of getting off, and controller sends unlocking signal to the maneuvering valve of getting off.
Further, described controller sends guide's electromagnetic cartridge valve that locked signal gets off on maneuvering valve described in and obtains electricly, and the maneuvering valve of getting off is locked, the joystick of now handling the maneuvering valve of getting off get off cross cylinder and not action of Vertical Cylinders.
Further, described controller sends guide's electromagnetic cartridge valve dead electricity that locked signal is got off on maneuvering valve described in, and the maneuvering valve of getting off is locked, the joystick of now handling the maneuvering valve of getting off get off cross cylinder and not action of Vertical Cylinders.
Further, described controller sends guide's electromagnetic cartridge valve dead electricity that unlocking signal is got off on maneuvering valve described in, the maneuvering valve release of getting off, and the joystick of now handling the maneuvering valve of getting off can carry out normal horizontal support legs and vertical leg operation.
Further, described controller send guide's electromagnetic cartridge valve that unlocking signal gets off on maneuvering valve described in obtain electric, the maneuvering valve release of getting off, the joystick of now handling the maneuvering valve of getting off can carry out normal horizontal support legs and vertical leg operation.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, the whether locked descending valve of automatic decision in the process of hoisting crane work, prevent the safety misadventure causing getting off faulty switching when crane job, support personnel and device security.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present invention;
Fig. 2 is workflow diagram of the present invention.
The specific embodiment
As shown in Figure 1, crane descending supporting leg locking device of the present invention, comprise controller, the change-over switch of getting on or off the bus, guide's enable switch and the maneuvering valve of getting off, the change-over switch of getting on or off the bus is electrically connected to controller signals input end, guide's enable switch is electrically connected to controller signals input end, and the maneuvering valve of getting off is electrically connected to controller signals mouth; The maneuvering valve of getting off comprises guide's electromagnetic cartridge valve, and guide's electromagnetic cartridge valve is electrically connected to controller signals mouth; Guide's electromagnetic cartridge valve is two-position three-way electromagnetic inserted valve.
According to the different choice of guide's electromagnetic cartridge valve working position, provide two kinds of methods of using this crane descending supporting leg locking device to control the supporting leg of getting off:
Method one, as shown in Figure 2, when carrying out hoisting operation, hoisting crane need open guide's enable switch, when detecting enable switch and be opening, controller sends locked signal to the maneuvering valve of getting off, it is guide's electromagnetic cartridge valve dead electricity, the joystick of now handling the maneuvering valve of getting off get off cross cylinder and the non-telescope action of Vertical Cylinders, the supporting leg of getting off is locked; When controller detects guide's enable switch in closed condition, controller can continue to detect gets on or off the bus change-over switch in for which working position, and this switch has two working positions: upper parking stall and parking space; When detecting it in upper parking stall, controller illustrates that now hoisting crane is in hoisting operation operating mode, controller sends locked signal, guide's electromagnetic cartridge valve of getting off on maneuvering valve obtains electric, the maneuvering valve of getting off is locked, the joystick of now handling the maneuvering valve of getting off get off cross cylinder and not action of Vertical Cylinders; When controller detects it when getting off working position, car load is in the working condition of getting off, controller sends unlocking signal to the maneuvering valve of getting off, guide's electromagnetic cartridge valve dead electricity of getting off on maneuvering valve, the maneuvering valve release of getting off, the joystick of now handling the maneuvering valve of getting off can carry out normal horizontal support legs and vertical leg operation.
