Description
Technical Field
The invention relates to the field of hydraulic systems, in particular to a hydraulic system with an integral box hopper with manual emergency lifting.
Background
At present, all the integral garbage compression boxes for compressing domestic garbage are provided with no hopper manual emergency lifting system. This mode of operation: 1. because the position and time of the power system with faults can not be predicted in advance, the probability of the power system of the hopper with faults at any point of the motion trail of the power system is the same. 2. The power bin provided with the power system is usually arranged at a certain position on the motion path of the hopper swing arm (considering that the storage bin and the compression bin are convenient to install and maintain, and the power bin is generally not arranged at the position where the hopper ascends in place), so that when the power system breaks down, the hopper swing arm possibly blocks a power bin door, and the power system cannot be pulled out for troubleshooting and maintenance. 3. If the oil pipe of the hopper oil cylinder is removed, the position of the hopper is changed by external force or gravity, and the weight of the hopper is heavy, regeneration accidents which harm the personal safety of maintenance personnel and the like can be caused. 4. When the problem of faults is large and the faults cannot be eliminated on site and need to be pulled to a maintenance factory for elimination, if the hopper is not lifted to the proper position, the lifting ring of the whole box can be blocked, and the hook arm vehicle cannot be hooked to the lifting ring for transferring.

Drawings
The invention is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a schematic diagram of the present invention.
Detailed Description
As shown in fig. 1, the hydraulic system with manual emergency lifting for the integral box hopper comprises a motor 1, a hydraulic pump 2, a three-position four-way O-shaped electromagnetic directional valve 5, a first one-way valve 3, a second one-way valve 9, a two-position two-way electromagnetic directional valve 7, a hopper oil cylinder 6, a high-pressure ball valve 8, a manual pump 11 and an oil tank 12;
the motor 1 drives the hydraulic pump 2 to work;
an oil suction port of the hydraulic pump 2 is connected with an oil tank 12 through a pipeline, a pressure oil port of the hydraulic pump 2 is connected with an oil inlet of a first check valve 3 through a pipeline, an oil outlet of the first check valve 3 is connected to a P port of a three-position four-way O-shaped electromagnetic reversing valve 5 through a pipeline, a T port of the three-position four-way O-shaped electromagnetic reversing valve 5 is connected with an oil return tank 12 through a pipeline, and a B port of the three-position four-way O-shaped electromagnetic reversing valve 5 is connected to a rod cavity of a hopper oil cylinder 6 through a pipeline;
an oil outlet of the two-position two-way electromagnetic reversing valve 7 is connected to a rodless cavity of the hopper oil cylinder 6, and an A port of the three-position four-way O-shaped electromagnetic reversing valve 5 is connected to an oil inlet of the two-position two-way electromagnetic reversing valve 7 through a pipeline;
an oil suction port of the manual pump 11 is connected with the oil tank 12 through a pipeline, and a pressure oil port of the manual pump 11 is connected with an oil inlet of the second one-way valve 9 through a pipeline;
an oil outlet of the second one-way valve 9 is connected to a pipeline between an A port of the three-position four-way O-shaped electromagnetic reversing valve 5 and an oil inlet of the two-position two-way electromagnetic reversing valve 7 through a pipeline;
one end of the high-pressure ball valve 8 is connected to an oil outlet of the second one-way valve 9 through a pipeline, and the other end of the high-pressure ball valve 8 is connected to a pipeline between a port B of the three-position four-way O-shaped electromagnetic reversing valve 5 and a rod cavity of the hopper oil cylinder 6 through a pipeline.
The hydraulic pump further comprises an electromagnetic overflow valve 4, a P port of the electromagnetic overflow valve 4 is connected to a pipeline between a pressure oil port of the hydraulic pump 2 and an oil inlet of the first check valve 3 through a pipeline, and a T port of the electromagnetic overflow valve 4 is connected with an oil return tank 12 through a pipeline. The pressure oil delivered by the hydraulic pump 2 has enough pressure to push the hopper cylinder 6 to extend and retract through the electric pressurization of the electromagnetic overflow valve 4, so that the hopper is pushed to normally rise and fall, and the system is ensured not to damage parts through overpressure operation. The first check valve 3 prevents the motor 1, the hydraulic pump 2 or the electromagnetic overflow valve 4 from suddenly breaking down in the hopper lifting process, and pressure oil in a rodless cavity of the hopper oil cylinder 6 cannot reversely flow through the hydraulic pump 2 or the electromagnetic overflow valve 4 and rapidly flow back to the oil tank 12, so that the sudden and rapid hopper descending can endanger the personal safety of workers.
The invention also comprises an overflow valve 10, wherein a P port of the overflow valve 10 is connected to a pipeline between a pressure oil port of the manual pump 11 and an oil inlet of the second check valve 9 through a pipeline, and a T port of the overflow valve 10 is connected with an oil return tank 12 through a pipeline. The overflow valve 10 ensures that the pressure output by the manual pump 11 cannot be overpressured to cause regeneration faults such as system element damage and the like
The working principle of the invention is as follows: in normal operation, the high pressure ball valve 8 is in a closed state. The motor 1 drives the hydraulic pump 2 to work, and pressure oil is sucked from the oil tank 12 to the pressure port of the hydraulic pump 2 and is pumped. The electromagnetic overflow valve 4 is electrically pressurized, and the system pressure is ensured not to be over-pressurized. The pressure oil delivered from the hydraulic pump 2 enters a P port of a three-position four-way O-shaped electromagnetic directional valve 5 through a first one-way valve 3. When the electromagnet at the left end of the three-position four-way O-shaped electromagnetic reversing valve 5 is electrified, pressure oil flows out from the port A of the three-position four-way O-shaped electromagnetic reversing valve and enters the rodless cavity of the hopper oil cylinder 6 through the two-position two-way electromagnetic reversing valve 7, oil flowing out from the rod cavity of the hopper oil cylinder 6 passes through the three-position four-way O-shaped electromagnetic reversing valve 5 and flows out from the port T of the three-position four-way O-shaped electromagnetic reversing valve to. When the electromagnet at the right end of the three-position four-way O-shaped electromagnetic reversing valve 5 and the two-position two-way electromagnetic reversing valve 7 are electrified, pressure oil flows out from the port B of the three-position four-way O-shaped electromagnetic reversing valve 5 and enters the rod cavity of the hopper oil cylinder 6, and oil flowing out from the rodless cavity of the hopper oil cylinder 6 passes through the two-position two-way electromagnetic reversing valve 7 and the three-position four-way O-shaped electromagnetic reversing valve 5 and flows out from the port T of the three-position four-way O-shaped electromagnetic reversing valve 5 and returns to the oil tank. A rodless cavity of the hopper oil cylinder 6 is provided with a two-position two-way electromagnetic reversing valve 7, when a rubber tube of the oil cylinder bursts, the hopper can be stopped at any position only by releasing the hopper operating button, and therefore life and property safety when the rubber tube bursts is guaranteed.
When the power system has a fault and needs to lift the hopper in an emergency, the high-pressure ball valve 8 is opened, the manual pump 11 is manually shaken, the manual pump 11 sucks oil from the oil tank 12, and pressure oil is conveyed to the pressure oil port of the manual pump 11. The pressure oil delivered by the manual pump 11 enters the rodless cavity of the hopper oil cylinder 6 through the second one-way valve 9 and the two-position two-way electromagnetic directional valve 7, so that the hopper is pushed to ascend. Hydraulic oil from a rod cavity of the hopper cylinder 6 also enters a rodless cavity of the hopper cylinder 6 through the high-pressure ball valve 8 and the two-position two-way electromagnetic directional valve 7, so that the hopper is quickly pushed to ascend, and the efficiency is greatly improved. The two-position two-way electromagnetic directional valve 7 ensures that pressure oil entering a rodless cavity of the hopper oil cylinder 6 cannot flow backwards, so that the safety and stability of emergency lifting of the hopper are ensured. The second check valve 9 ensures that the pressure oil in the rear oil path cannot flow reversely to influence the efficiency of the manual pump 11 for outputting the pressure oil and reduce the hand-cranking load.
In summary, it can be seen that the hydraulic system: 1. under the normal working condition, when the power source breaks down suddenly, the safety of the hopper can be ensured, and the sudden drop can not endanger the personal safety. 2. When a power system breaks down, the hopper can be conveniently lifted manually and emergently, so that the failure can be timely eliminated, and the garbage operation efficiency is ensured. 3. When the great maintenance factory that needs of transporting of trouble goes to overhauing, can guarantee the convenient timely hoist and mount of hook arm car and transport. 4. The manual emergency lifting hopper capable of rapidly and safely lifting the hopper guarantees the safety and efficiency of maintenance. 5. The life and property safety of the rubber hose in bursting is ensured.
