Description
Technical field
The invention belongs to the improved design projects of engineering machinery field component, more specifically, belong to one kind can be improved it is vertical
The step-down operation of straight column type electrohydraulic control system, practicability, safety design method.
Background technique
Aerial work platform be be serve various industries high altitude operation, equipment installation, maintenance etc. mobilitys high-altitude
The product of operation can send operator to the equipment of high altitude operation.Due to the particularity of operating environment, to aerial work platform
Each main component all put forward higher requirements.Important feature of the emergency decent system of vertical pillar as high altitude operation,
Its structure is improved, it is even more important to increase practicability.Existing vertical pillar electrichydraulic control emergency decent system valve block is mounted on oil
On cylinder, emergency decent system is arranged in the back side of vertical pillar, inconvenient for operation, safety is poor；In addition original power unit
With hydraulic oil container using split type, increase piping connection quantity, this design oil leak frequent occurrence in use, under the whole series are urgent
The manufacturing process of drop system is relative complex, higher cost.
Summary of the invention
The present invention is given and a kind of has both the improved of safety and practicability to efficiently solve the above technical problem
Vertical pillar electrichydraulic control emergency decent system device.
A kind of vertical pillar electrichydraulic control emergency decent system, including oil cylinder, transit joint 1, explosion-proof valve, hydraulic hose,
Transit joint 2 integrates power unit, solenoid valve, emergency descent bracing wire composition.It is characterized in that, explosion-proof valve passes through transit joint 1
It is directly rigidly attached on oil cylinder, has the characteristics that high reliablity and practical.
According to above-described vertical pillar electrichydraulic control emergency decent system, it is preferable that hydraulic hose passes through transit joint 2
It is flexibly connected explosion-proof valve and power unit.
According to above-described vertical pillar electrichydraulic control emergency decent system, it is preferable that change the electro-hydraulic control of former vertical pillar
Emergency decent system valve block processed is directly installed on oil cylinder.
According to above-described vertical pillar electrichydraulic control emergency decent system, it is preferable that hydraulic hose, using double-layer wire
Net, it is ensured that pressure is met the requirements.
According to above-described vertical pillar electrichydraulic control emergency decent system, preferentially, power unit is integrated, by function
Block, dynamical system and fuel tank integrate.
According to above-described vertical pillar electrichydraulic control emergency decent system, preferentially, emergency descent bracing wire passes through stud
It can be directly on the solenoid valve of integrated power unit.

Attached drawing 3 is vertical pillar electrichydraulic control emergency descent hydraulic principle schematic diagram；
Drawing reference numeral explanation: 1, oil cylinder, 2, transit joint 1,3, explosion-proof valve, 4, hydraulic hose, 5, transit joint 2,6, collection
At power unit, 7, solenoid valve, 8, emergency descent bracing wire, 9, platform, 10, column, 11, chassis.
Specific embodiment
It Fig. 1, Fig. 2, Fig. 3, is structural schematic diagram of the invention.
Fig. 1 is vertical pillar electrichydraulic control vehicle overall structure diagram of the invention, mainly by platform, column and bottom
Three, disk compositions.Vertical pillar electrichydraulic control emergency decent system of the invention uses explosion-proof valve and integrated power unit system,
Keep overall system structure compact, it is easy for installation, it is easy to maintenance, so that operator is used emergency descent device in side.Referring to
Fig. 2, oil cylinder 1 are mounted on first segment column by end trunnion by the mounting blocks of clearance fit, and the top of oil cylinder 1 passes through pin
Axis and connector are mounted on the second section column, and explosion-proof valve 3 is connected directly between the end of oil cylinder 1 by transit joint 2, hydraulic soft
Pipe 4 is connected explosion-proof valve 3 and integrated power unit 6 by transit joint 5, and integrated power unit 6 is connected by transition block bolt
It connects on chassis, 7 front end of emergency descent bracing wire is connected by stud with the decline solenoid valve of integrated power unit 6, emergency descent
The rear end of bracing wire 7 is connected by two sides nut and the baffle of chassis side, and after solenoid valve 3 is powered, spool switching direction, oil liquid can
To flow through, while design has restriction in valve, oil cylinder decrease speed can be made constant, solenoid valve 3 can also be manually
Switch spool, reaches same purpose.
The structure of vertical pillar electrichydraulic control emergency descent is improved, explosion-proof valve is improved, utilizes the pressure difference at inlet and outlet both ends
With the imbalance of spring force, when the flow in pipeline is more than setting value, two hydraulic fluid port pressure differences increase, and spring force is overcome to push valve
Core movement, cut-off loop, therefore can effectively prevent the decline accident out of control that hydraulic hose ruptures suddenly and occurs, while can be effective
The hydraulic oil in pipeline is prevented to leak.Hydraulic hose can effectively absorb vibration, while allow the relative displacement of oil cylinder part.Collection
Functional block and dynamical system are integrated at power unit, have leakage small, it is practical, it is highly-safe, it is at low cost etc.
Advantage, emergency descent bracing wire is mounted on the side of platform, convenient and simple for operation, meets the needs of high altitude operation.
