Abstract
The utility model provides a double-cylinder hydraulic lifting device adopting double-cylinder lifting, which consists of a gear pump assembly and two oil cylinders, wherein the gear pump assembly has the structure that an oil pump driven by a motor is arranged on the oil intake pipe of an oil groove, the oil pipe is divided into two paths with one path communicated with the oil groove through an overflow valve and the other path connected with the oil cylinder through a check valve, and the pipeline connected into the oil cylinder has a branch pipeline communicated with the oil groove through a hand-operated direction valve and a throttle valve. The double-cylinder hydraulic lifting device has a simple structure, is convenient to use, and greatly enhances the safety by adopting the double-cylinder lifting mode.
Description
Technical field
The utility model belongs to the auto parts and components field.
Background technique
The hydraulic lifting of existing automobile all is to adopt the single cylinder artificial lifting way, in the lifting process, very easily causes deflection, cause the accident, and the single cylinder lifting also very easily damages.
Summary of the invention
The purpose of the utility model provides a kind of double-cylinder hydraulic lift device that adopts the twin-tub lifting.
The utility model is divided into gear pump assembly and oil cylinder; Wherein oil cylinder has two; The gear pump assembly structure is: the oil pump through driven by motor is arranged on the oil inlet pipe of oil groove, and oil pipe is divided into two-way then, and one the tunnel communicates with oil groove through relief valve; Oil cylinder is sent into through one-way valve in another road, and the pipeline of sending into oil cylinder has a branch line to communicate with oil groove through hand-operated direction valve and throttle valve.
The utility model is simple in structure, and is easy to use, because the twin-tub pattern lifting of adopting, so increased Security greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is divided into gear pump assembly 2 and oil cylinder 1; Wherein oil cylinder 1 has two; Gear pump assembly 2 structures are: the oil pump 5 that drives through motor 4 is arranged on the oil inlet pipe of oil groove 9, and oil pipe is divided into two-way then, and one the tunnel communicates with oil groove 9 through relief valve 6; Oil cylinder 1 is sent into through one-way valve 3 in another road, and the pipeline of sending into oil cylinder 1 has a branch line to communicate with oil groove 9 through hand-operated direction valve 7 and throttle valve 8.
The lifting process:
Press switch rising button, relay adhesive machine operation, the gear pump oil suction is a bilateral oil cylinder fuel feeding, piston rod rising lifting operator cabin when oil cylinder guarantees the pressure unanimity.Exceed the overflow of oil pressure relief relief valve like system pressure, not lifting of oil cylinder, relay disconnection gear pump quits work when unclamping the rising button, and oil cylinder stops vertical motion, leans on the pump one-way valve to realize auto-lock function.
The falling process:
Press switch decline button, the solenoid valve switching-over, the oil cylinder piston bar leans on the operator cabin action of gravity to fall after rise.Solenoid valve adds manual Decompression valves in addition, and when solenoid valve did not have electricity and do not work, available manual Decompression valves was realized switching-over.
Seal ring is made up of 5 elements, the central ring that nitrile butadiene rubber is processed, two supporting rings that thermoplastic material is processed, and two guide rings of being processed by polyoxymethylene.This combined sealing ring can guarantee the low friction under high pressure, improves the working life of oil cylinder, and can prevent the poor sealing that the oil cylinder of single piston action is influenced by big lateral force.
