Description
Technical field
The utility model relates to a kind of hydraulic efficiency pressure system, particularly a kind of live hydraulic system of aerial platform workplatform.
Background technology
At present, aerial platform is widely used in the aloft work of every profession and trade with the characteristics of its maneuverability.The highest in the world aerial platform has reached hundred meters.Under this big operation height, for workplatform provides the pipeline of hydraulic oil very long, the watt loss along stroke pressure loss and car load of pipeline is bigger, thereby has increased the hydraulic pressure cost of car load, and economy is bad.In addition, for hydraulic oil is served workplatform, the flat-bed that pushes the work forward action needs on the aerial platform to arrange corresponding towing chain mechanism that its complex structure has increased complete vehicle quality simultaneously, has further influenced the stability of aerial platform workplatform.
Summary of the invention
For the hydraulic efficiency pressure system energy consumption that overcomes existing aerial platform is big, the shortcoming that towing chain mechanism is complicated, the utility model provides a kind of live hydraulic system of aerial platform workplatform.
The purpose of the utility model is to reach through following measure: the live hydraulic system that a kind of aerial platform workplatform is provided.The live hydraulic system of said aerial platform workplatform comprises power unit, control part, power train control module and is installed in the independent hydraulically controlled power unit 7 of two covers of workplatform 4; Two gear type pumps 9 are equipped with in fuel tank 8 inside; Gear type pump 9 links to each other with two motors 12 respectively through contiguous block 11; Fuel tank 8 is connected with platform valve group 10 oil circuits respectively with gear type pump 9; Power unit is electrically connected with electrical motor 12; Control part and the independent hydraulically controlled power unit of two covers 7, power unit signal are connected.
One preferred version is: said power unit is mounted in the storage battery of workplatform 4.
One preferred version is: said power unit is mounted in the direct supply of turntable 1, and the power lead that connects power supply and electrical motor can be through cable reel 18 automatically regulatings that are installed in jib 3.
One preferred version is: the Hydraulic Pump outlet is connected with energy storage 14.
One preferred version is: said power train control module can be controlled the alternation of two motors 12.
One preferred version is: said control part further comprises motor fault warning, electric quantity of power supply indication and electrical motor high temperature alarm.
Beneficial effect: the live hydraulic system that the utility model discloses a kind of aerial platform workplatform.It can make the aerial platform workplatform save long pipe runs and towing chain mechanism on the jib, reduces the loss in efficiency and the cost of system, improves the speed of response of workplatform simultaneously, makes car load more stable.Adopt double-motor and gear type pump in addition, hot spare has each other guaranteed the safety and the reliability of system works.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
With reference to accompanying drawing, in the present embodiment, the live hydraulic system of aerial platform workplatform comprises power unit, control part, power train control module and is installed in the independent hydraulically controlled power unit 7 of two covers of workplatform 4; Two gear type pumps 9 are equipped with in fuel tank 8 inside; Gear type pump 9 links to each other with two motors 12 respectively through contiguous block 11; Fuel tank 8 is connected with platform valve group 10 oil circuits respectively with gear type pump 9; Power unit is electrically connected with electrical motor 12; Control part is connected with the power train control module signal.
The live hydraulic system of said aerial platform workplatform has been saved long pipe runs and the towing chain mechanism 2 on the jib, and the speed of response of platform action is faster, and energy consumption is low.In addition, gear type pump 9 is placed on hydraulic reservoir inside, both can saves the space, can increase again gear type pump from absorption, simultaneously can also play dustproof effect, make the structure of power unit compact more.Two electrical motors 12 and two gear type pumps 9 have been designed in the hydraulic power unit; Two covering device alternations are platform valve group fuel feeding, and this has solved the problem that the electrical motor work-hours is short, heating is bigger on the one hand, and two overlap propulsions source hot spare each other on the other hand; When wherein a cover system goes wrong; Another set of system can take over immediately and devote oneself to work, and control system is understood the alarm operator simultaneously, thereby has guaranteed the safety and the reliability of system works.
Workflow: when the action of operator's operating handle control jib 3 luffings; Controller can be given the power train control module signal simultaneously, actuating motor 12 one of them, the motor drives gear type pump operates as platform valve group 10 fuel feeding; Fluid gets in the leveling cyclinder 16; The promotion oil cylinder stretches out or withdraws, and drives platform and moves, simultaneously adjusting work platform 4 levels; When platform arrived assigned address, the operator stopped the luffing action, and controller is also given the power train control module signal simultaneously, stops electrical motor.
When operator's continuous handling jib 3 luffings or workplatform 4 actions, according to the rotating speed and the pressure of tachogen and oil pressure sensor 13 detections, two electrical motors 12 of controller control are with certain rotating speed alternation.If during one of them electrical motor 12 work; When controller inside detects excessive or other abnormality of electric current; Controller stops this electrical motor 12 through power train control module at once, and starts another electrical motor 12 work, also can report to the police on the control panel of platform 4 simultaneously; Fault has appearred in prompting operation person's electrical motor, in time overhaul.
Above content is to combine optimal technical scheme to the further explain that the present invention did, and can not assert that the practical implementation of invention only limits to these explanations.Under the present invention, the those of ordinary skill of technical field, under the prerequisite that does not break away from design of the present invention, simple deduction and replacement can also be made, all protection scope of the present invention should be regarded as.
