It closes, four control operation handles being adjusted up in hydraulic control device 63 keep 3 piston rod of transverse hydraulic oil cylinder mobile, make to rise
5 horizontal spreading of descending branch leg assembly is to utmostly；
Step 2: four operation handles in hydraulic control device 63 are playbacked, then four operation handles are adjusted downwards,
The piston rod of four longitudinal hydraulic cylinders 51 is longitudinally unfolded along the direction of piston rod, until with ground face contact, entire vehicle-mounted self-chambering
Platform is unloaded not have to get off.
4) after vehicle-mounted Self-loading-unloading platform expansion, if there is ground out-of-flatness, leveling step:
Step 1: being changed when 5 longitudinal direction of liftable leg assembly is expanded to contact ground using the flexible rotation of supporting leg seat 52
Become the angle of liftable leg assembly 5 and ground face contact, to reach leveling.
Step 2: if testing ground road quality is very poor, when having uneven, in the longitudinal exhibition of liftable leg assembly 5
After opening, liftable leg assembly 5 between ground at a distance from differ, can use in hydraulic control device 63 four controls operation
Handle balances come every lifting of liftable leg assembly 5 of fine adjustment respectively to reach.
Therefore, the vehicle-mounted Self-loading-unloading platform of the present embodiment can be automatically performed up and down without crane cooperation
Vehicle, operating process is simple, reliable, work efficiency is high, is very suitable for the field test of super extra-high voltage equipment.
In conclusion the vehicle-mounted Self-loading-unloading platform whole process of the present embodiment cooperates without crane, but pass through the hydraulic of oil cylinder
Device adjusts the flexible of 4 pedipulators, and Lai Shixian platform is got on or off the bus.When the road out-of-flatness of testing ground, testing equipment can
It can tilt, there are security risks, can be at the scene according to surface conditions to the height of 4 legs using vehicle-mounted Self-loading-unloading platform
It is adjusted, not only saves manpower, can be improved installation effectiveness, it is most important that greatly reduce installation problems, improve peace
Quan Xing.It is automatic that the implementation of the vehicle-mounted Self-loading-unloading platform of the present embodiment realizes the vehicular platform at laboratory and field test
It gets on or off the bus and pot hole is not finely adjusted usually to reach balance at the scene, solve at the scene and above and below platform when laboratory
Vehicle needs crane to cooperate, and platform can not be integrally placed in indoor problem, reduces the input of manpower and material resources, eliminates spy
Security hidden trouble existing for kind equipment operation, improves the convenience of platform.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
