The utility model realizes pneumatic case opening by operation in a driving cab and ensures that the case door (4) in a transportation process is locked fixedly, safely and reliably.
Description
Technical field
The utility model relates to tip-up lorry, relates in particular to the unpacking device of dumping car.
Background technology
The mechanical type of the present domestic dumping car device of unpacking, it is board-like etc. to mainly contain locking bar formula, tightening latch bolt, when unloading, open with the lifting of dumping car casing, though this class formation can be supporting with dumping car, but convenient inadequately, can't in operator's compartment, handle, more bothersome, time has been grown also and can be out of shape, and influence is used.Device is unpacking by electrical control, locking to also have a class to unpack automatically, and is easy to use, flexible operation, by the bottom-up chamber door that hooks of latch hook of air chamber, the necessary pressure abundance of this structure gas circuit hooks with the air pressure pressurization all the time, if insufficient pressure or fault then can't guarantee the safety of locking a door.
Summary of the invention
The purpose of this utility model just provides a kind of can the manipulation and unpacks in operator's compartment, easy to use, improves dumping car unloading operation efficient, can guarantee to pin chamber door again, safe and reliable novel unpacking mechanism.
Task of the present utility model is finished like this: design a kind of dumping car pneumatic unpacking mechanism of coupling type, form by pneumatic control system and unpacking mechanism, supporting with dumping car, pneumatic control system comprises master cock, gas circuit, change-over valve, unpacking mechanism comprises air chamber, the air chamber support, connecting rod, link, air chamber is installed on the air chamber support of the cargo floor below of being fixed in dumping car, the air chamber push rod connects connecting rod by the push rod bearing pin, the connecting rod other end connects link by pitman pin, the connecting rod middle part is mounted on the air chamber support by rack pin shaft, and link can be hitched with the hook on the air chamber support and cooperate.The hook rear end is fixed on the air chamber support, and front end stretches out the cargo floor outside, and the jam plate of dumping car chamber door bottom can overlap and be buckled on the hook, and hook is hitched and chamber door and cargo floor can be locked in link.The control end of change-over valve connects master cock, and admission port is communicated with pressure gas source by gas circuit, and air extractor duct is equipped with check valve by the air chamber of the unpacking mechanism of gas circuit connection on the branch road of gas circuit.Change-over valve can be selected solenoid directional control valve or Pneumatic reversal valve for use, and air chamber can be that brake compressor also can be a cylinder.During work, by master cock cut-in pressure source of the gas, pressure gas enters air chamber through change-over valve, the air chamber push rod is extrapolated, and drivening rod rotates around rack pin shaft, tilts upward in the connecting rod outer end, drive link by the link bearing pin and upwards lift, by gravity breaks off relations and falls, and chamber door is opened voluntarily.Discharged, the closing control switch, the gas in the air chamber is discharged by the exhausr port of change-over valve, and the air chamber push rod resets, and drivening rod resets, and staff hangs over the link pull-up on the hook that leans out the chamber door jam plate at this moment, is about to chamber door and pins sealing.Such structure keeps the chamber door locking not need to use gas, and link promptly hangs over hook tightly and goes up the locking chamber door.Open chamber door, must start the pneumatic control system mechanism that promote to unpack, therefore as safe as a house in transportation at ordinary times.
Design and produce, test according to above-mentioned, prove that the utility model is rational in infrastructure, easy to operate, flexible, realized in operator's compartment, handling pneumatic unpacking, both can improve the dumping car rate of discharging, can guarantee that again chamber door is closed locking in the transportation, safe and reliable, reached predetermined purpose preferably.
