Description
Technical field
The utility model relates to a kind of hydraulic control lowering or hoisting gear, specifically relates to a kind of remote control hydraulic control pedal lowering or hoisting gear.
Background technique
The hydraulic control elevating system is that the motion by oil hydraulic cylinder or oil hydraulic motor drives the device that load is risen or descended, have carrying capacity big, operate steadily, advantages of simple structure and simple.But the switch of elevating system all is mechanical pull-rod type, finishes by the manual draw bar operation, and this switch has increased certain manual labor, and noise is arranged.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that prior art exists, the utility model proposes a kind of remote control hydraulic control pedal lowering or hoisting gear, this device can be realized manual control, remote control and automatically controlled three kinds of modes of operation, has high reliability.
Technological scheme: for solving the problems of the technologies described above, remote control hydraulic control pedal lowering or hoisting gear of the present utility model comprises the hydraulic system that drives pedal, the remote-controlled valve, the Direct box that are connected with hand control valve on the hydraulic system, controlled by remote controller; Hand control valve is connected on the pump oil pipe line; The P of remote-controlled valve
SMouth is connected the P of remote-controlled valve with the pump oil pipe line
A, P
BTwo hydraulic fluid ports are connected with oil cylinder; The coil of remote-controlled valve is connected with Direct box; Direct box connects power supply.
Remote control and manual throw over switch button and coil control knob are arranged on the Direct box.
Behind the oil hydraulic pump fuel feeding, high pressure oil enters remote-controlled valve through hand control valve, handles remote controller, the remote-controlled valve action, and high pressure oil enters two hydraulic jacks through remote-controlled valve by hydraulic lock.When A that handles remote controller or C, piston rises pedal.Whenever, any position can be handled the A or the C of remote controller once more, and then pedal will be parked in desired position.When waiting to finish required task, can handle the B or the D knob of remote controller, pedal is slowly downwards up to the desired position.When pedal (during limit position) on earth, by the B or the D button of a remote controller, at this moment, pedal just is locked in original position again.The utility model also can carry out automatically controlled.Four electromagnetic coils of remote-controlled valve are controlled in the throw over switch fingertip control remote control of Direct box and automatically controlled conversion, coil control knob respectively.By " 1 " number button, the A coil motion, the high pressure oil that comes from oil hydraulic pump enters remote-controlled valve by oil filter and hand control valve, enters the bottom of hydraulic cylinder piston by hydraulic lock, and piston protrudes upward, and promotes the pedal rise.Whenever, once " 1 " number button all can be pressed again in any position, in case release button, pedal just is parked on the desired position; When needing pedal to descend, by " 2 " number button, press once " 2 " number button again, pedal descends and stops; If do not stop, repeat to handle " 2 " number button, till satisfaction to desired location.In like manner, handle " 3 " or " 4 " fingertip control pedal lifting.When remote-controlled valve breaks down, by handling hand control valve, but system's proper functioning still.
Beneficial effect: the utility model is the new product of electronic technology and hydraulics combination, and three remainings are arranged, i.e. remote control, automatically controlled and manual has high reliability; The utlity model has purposes widely, can be used for outside the vehicle transport semitrailer, hydraulic tipper, hydraulic pressure winch etc.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in drawings, remote control hydraulic control pedal lowering or hoisting gear comprises the hydraulic system that drives pedal 6, the remote-controlled valve 2, the Direct box 3 that are connected with hand control valve 1 on the hydraulic system, controlled by remote controller; Hand control valve 1 is connected on the pump oil pipe line 4; The P of remote-controlled valve 2
SMouth is connected the P of remote-controlled valve with pump oil pipe line 4
A, P
BTwo hydraulic fluid ports are connected with oil cylinder 5; The coil of remote-controlled valve 2 is connected with Direct box 3; Direct box 3 connects power supply; On the oil cylinder 5 of hydraulic system pedal 6 is arranged.
Remote control and manual switching button 7 and coil control knob 8 are arranged on the Direct box 4.
Every group of pedal 6 is by the 5 control liftings of two oil cylinders, by the oil hydraulic pump fuel feeding, high pressure oil enters remote-controlled valve 2 through hand control valve 1, handle remote controller, radio signal is amplified the coil that enters remote-controlled valve 2 through Electronic Control Box 3, remote-controlled valve 2 actions, high pressure oil enters two hydraulic jacks 5 through remote-controlled valve 2 by hydraulic lock 9.When A that handles remote controller or C, high pressure oil enters hydraulic jack 5 bottoms, and the piston of oil cylinder 5 moves upward, and piston rises pedal 6.Whenever, any position can be handled the A or the C of remote controller once more, and then pedal 6 will be parked in desired position.When waiting to finish required task, can handle the B or the D knob of remote controller, at this moment high pressure oil enters the other end of hydraulic jack 5 pistons by hydraulic lock 9, with hydraulic cylinder piston to pressing down, the oil of the other end is got back to fuel tank by hydraulic lock 9 from another pipeline, and pedal 6 is slowly downwards up to the desired position.When pedal 6 (during limit position) on earth, by the B or the D button of a remote controller, at this moment, pedal 6 just is locked in original position again.
This system also can carry out automatically controlled.The throw over switch button 7 control remote control and the automatically controlled conversions of Direct box, coil control knob 8 has four, and " 1 " " 2 " " 3 " " 4 " are controlled remote-controlled valve A, B, four electromagnetic coils of C, D respectively.By " 1 " number button, the A coil motion, the high pressure oil that comes from oil hydraulic pump enters remote-controlled valve 2 by oil filter and hand control valve 1, enters the bottom of hydraulic cylinder piston by hydraulic lock 9, and piston protrudes upward, and promotes pedal 6 rises.Whenever, once " 1 " number button all can be pressed again in any position, in case release button, pedal 6 just is parked on the desired position; When needing pedal 6 to descend, by " 2 " number button, press once " 2 " number button again, pedal descends and stops; If do not stop, repeat to handle " 2 " number button, till satisfaction to desired location.In like manner, handle " 3 " or " 4 " fingertip control pedal lifting.
When remote-controlled valve 2 breaks down, when stuck, make remote-controlled valve 2 be in the right side or left position by manual methods, at this moment, by handling hand control valve 1, but system's proper functioning still.
There are three remainings in this system, i.e. remote control, automatically controlled and manual, and system has high reliability.Be that electronic technology and hydraulics are combined into the incorporate new product of mechano-electronic, have purposes widely, except the vehicle transport semitrailer, hydraulic tipper, hydraulic pressure winch etc. can adopt; Electronic Control Box 3 is critical products of signal conversion and amplification; The coupling of remote-controlled valve 2 and electronic controller is the key technology of signal transmission.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
