Description

The automatic lifting device that is used for power actuated vehicle and analogue
Technical field
The present invention relates to be used for the automatic lifting device of power actuated vehicle and analogue.
Background of invention
In the apparatus field that is used for the power actuated vehicle hospital, known use automatic lifting device rises to a certain height on the ground generally with power actuated vehicle, thereby be convenient to the work that the operator maintains or repairs on described power actuated vehicle, in some cases, allow to arrive the bottom on power actuated vehicle chassis.
Especially, automatic lifting device under the known so-called vehicle body, basically by being used between decline state and propradation moving described flat-bed one mechanism by insertion and constituting this equipment about the related base of the platform of loader motor vehicle, described mechanism is mechanical or fluid-operated pattern to this equipment.
Platform is provided with the structure that is used to support power actuated vehicle, and this structure is suitable for being engaged on the so-called all raised position of the necessary ingear of automatic lifting device, so that guarantee the balance of during movement described mechanism vehicle.
Determine the arrangement and the size of these raised position at the during the design of power actuated vehicle, and suitably strengthened, so that avoid the fracture or the damage of vehicle body.
According to present applicable standard, the arrangement of the raised position of the power actuated vehicle that may change from a model to another model is being indicated corresponding Operation and maintenance handbook by manufacturer, and indicates on the chassis by corresponding benchmark.
In use, the power actuated vehicle that be raised is placed on the automatic lifting device, and is configured to make loading platform to be in the decline state: the operator places all supportive devices in indicated all raised position, and the actuation movement device, rises to cause platform.
Supportive device can be two types.
In one first situation, loading platform is made of the narrow platform of interior distance between shafts than all wheels of power actuated vehicle, thereby described machine power actuated vehicle can be set on this platform, and do not travel on it, and supportive device by a plurality of arms, be generally four arms and constitute, each arm can pivot at this flat-bed corner separately and be provided in the district, and this district has can be along the cushion rubber of described arm slip.
After power actuated vehicle being positioned on this platform of decline state, the operator must descend bending, so that reach all arms, rotate them and produce moving of corresponding cushion rubber, so that place them in all raised position that to carry out the power actuated vehicle of interventional procedure on it.
Replace as one, loading platform can have a width of the chassis width that equals power actuated vehicle at least, so that have all lateral strips, each lateral strip is set under the side of power actuated vehicle, before corresponding and between the trailing wheel, and supportive device is made of a plurality of cushion rubbers, common four cushion rubbers, and cushion rubber can be arranged on the described platform, under all raised position of power actuated vehicle.
After the power actuated vehicle that will carry out interventional procedure on it was positioned on the platform in the decline state, the operator must be crooked, and cushion rubber is placed between the chassis of this platform and power actuated vehicle, under corresponding all raised position.
These automatic lifting devices have shortcoming, these shortcomings comprise wherein force position that the operator works and he to the limited visual field of the bottom on power actuated vehicle chassis, about the work that all cushion rubbers is positioned at all raised position of self-propelled vehicle be very inconvenient and feasible hardly, and may have danger for the globality of operator's safety and power actuated vehicle.
In fact the operator must move along the periphery of power actuated vehicle when floor level is crooked so that to all cushion rubbers location, if he does not correctly place them once in a while, power actuated vehicle may fall from platform during promoting so.
Summary of the invention
Aim of the present invention is to eliminate above-mentioned shortcoming by the automatic lifting device that is provided for power actuated vehicle and analogue, and this equipment allows to be provided at all cushion rubbers more convenient of corresponding all raised position and the location of safety.
In this aim, a purpose of the present invention provides simply, in fact is easier to that provide, safe in utilization, efficient in operation and has the automatic lifting device of lower cost.
Following meeting become more obviously this aim and these and other objects have been realized by the automatic lifting device that is provided for power actuated vehicle and analogue, this equipment comprises loading platform, can be bonded under the body of power actuated vehicle or analogue by supportive device, the loading platform that inserts a plurality of raised position that can be arranged on described power actuated vehicle; And be used between decline state and propradation moving described flat-bed device; The device that also comprises all wheels that are used to support power actuated vehicle, this device links to each other with described platform by the unit that insertion is used to drive, this move have between described platform and the described supportive device at least one with respect to another the perpendicular direction, be used to locate a state of described supportive device and be used at the mutual motion of translation of getting involved on the power actuated vehicle between the state of work; At a state that is used for locating described supportive device, described supportive device is set near one of the described flat-bed height in the lifting state and highly locates, and power actuated vehicle is loaded on the described supportive device; At the state that is used for carrying out interventional procedure on power actuated vehicle, described supportive device is set at than the remarkable lower position of platform described in the propradation, and is loaded on the described platform by inserting described supportive device power actuated vehicle; The moving period from the decline state to propradation, described supportive device is rigidly connected in platform basically, and power actuated vehicle is loaded on the described supportive device.
