Abstract
A synchronous sealing vehicle closed hydraulic system belongs to a hydraulic control system of engineering machinery, which is the combination of a closed variable plunger pump, various supraposition hydraulic control valves and hydraulic motors. With the control of PLC electronic signals on the vehicle, the synchronous sealing work of the hydronic heating of asphalt, the spraying of asphalt, the spreading of stone chips, the feeding of stone chips bins, and the like, can be realized in a coordinating way. Compared with open hydraulic systems, the hydraulic system is characterized by simple structure, few joints, and being easy to be adjusted and repaired.
Description
Technical field
The invention belongs to the hydraulic control system of engineering machinery.
Background technique
Synchronous chip sealer is that road can realize synchronously that distributing asphalt and aggregate chips finish the engineering truck of road seal.And coordinate to realize to pitch circulation heating, pitch spray, to spill cloth be by the HYDRAULIC CONTROL SYSTEM of synchronous chip sealer to aggregate chips.The hydraulic system of synchronous chip sealer generally adopts open type hydraulic system at present, promptly by main oil pump the hydraulic oil of fuel reserve tank is got, and returns fuel reserve tank after each hydraulic control motor or oil cylinder acting.Adopt this open hydraulic control system exactly as domestic TBS3500 type chip sealer.The open type hydraulic system complex structure, contact is many, rate of fault is high, adjust difficulty, its fuel reserve tank is also bigger.Along with the raising of engineering machinery technical merit and the innovation and development of hydraulic pressure components and parts, the hydraulic system of new generation of researching and developing a kind of synchronous chip sealer is imperative.
Summary of the invention
The objective of the invention is to use the new type hydraulic components and parts, for synchronous chip sealer design a kind of simple in structure, the pipeline contact is few, rate of fault is low, be easy to adjust, control hydraulic control system flexibly.
For achieving the above object, technological scheme of the present invention provides a kind of closed hydraulic system for synchronous chip sealer, it is by enclosed Variable plunger pump (1), total pressure regulation superposing control valve (C), bitumenpump drive motor superposing control valve (D), dial aggregate chips material roller drive motor superposing control valve (E), Heat-transfer Oil Pump drive motor superposing control valve (F), aggregate chips feed bin oil cylinder lifting superposing control valve (G) and bitumenpump oil hydraulic motor (14), dial aggregate chips oil hydraulic motor (13), Heat-transfer Oil Pump oil hydraulic motor (12), aggregate chips feed bin oil cylinder (11), pipeline pressure filter (2), cooling flushing valve (3), oil pressure gauge (4), radiator (15), return filter (16), oil suction filter (17), fuel tank (18), channel plate (10) and hydraulic pressure transfer pipeline are formed, and its total pressure regulation superposing control valve (C) is that two position and four-way reversing valves (5) and relief valve (6) stack are assemblied on the channel plate (10); Bitumenpump, drive motor superposing control valve (D), group aggregate chips material roller drive motor superposing control valve (E), Heat-transfer Oil Pump drive motor superposing control valve (F) are three position four-way directional control valve (7) and throttle valve (8) stack is assemblied on the channel plate (10); Aggregate chips feed bin oil cylinder lift controil valve (G) is that selector valve (7) and bidirectional hydraulic lock (9), throttle valve (8) stack are assemblied on the channel plate (10), channel plate (10) is fixed on the synchronous chip sealer left front, and two passwaies are connected for two mouthfuls with A, the B of enclosed Variable plunger pump respectively.
With open type hydraulic system relatively, the present invention has that system architecture is simple, contact is few, be easy to adjust and advantages such as maintenance.
Description of drawings
Fig. 1 is structure of the present invention and working principle schematic representation.
As shown in the figure, the present invention is by close circuit variable pump (1), total pressure regulation superposing control valve (C), pitch Pump drive motor superposing control valve (D), group aggregate chips material roller CD-ROM drive motor superposing control valve (E), Heat-transfer Oil Pump CD-ROM drive motor superposing control valve (F), aggregate chips feed bin oil cylinder lift controil valve (G), bitumenpump hydraulic motor (14), Dial aggregate chips hydraulic motor (13), Heat-transfer Oil Pump hydraulic motor (12), aggregate chips feed bin oil cylinder (11), channel plate (10), pipeline pressure filter (2), cooling flushing valve (3), oil pressure gauge (4), radiator (15), Return filter (16), oil absorption filter (17), fuel tank (18), two position and four-way reversing valves (5) and excessive Stream valve (6), three position four-way directional control valve (7), choke valve (8), bidirectional hydraulic lock (9) form.
Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are described in detail:, manually the ratio of revolutions of each motor in the hydraulic system is adjusted by the throttle valve (8) in each superposing control valve in advance according to the construction needs.
The diesel engine of opening on the car drives enclosed Variable plunger pump (1) rotation by universal joint, interior tool slippage pump rotates simultaneously to system mends full hydraulic oil, and from A mouth output high pressure oil inlet passage plate (10), get back to the low pressure pipeline of channel plate by total pressure regulation superposing control valve (C), enter main pump from the B refluxing opening, guarantee the non-loaded startup of main pump.During construction operation, according to the solenoid valve work in the automatically controlled program control enclosed of PLC on the synchronous chip sealer Variable plunger pump (1), cutoff high oil district is to the passage in low pressure oil district, make the A mouth be in high pressure conditions, handled the variable cylinder action in the enclosed Variable plunger pump (1), and then the main pump swash plate that promotes in the enclosed Variable plunger pump changes, and changed the output flow of main pump, reaches the feed rate of press speed ratio variation and aggregate chips feed bin oil cylinder (11) of each oil hydraulic motor (14) (13) (12).When the B point was in low-pressure state, 1/3rd of hydraulic oil total discharge entered radiator (15) cooling.The draining of enclosed Variable plunger pump (1) and the draining of each motor all can flow through filter (16) through threeway gets back to utilization again in the fuel tank (18).
