Creeper undercarriage described in the present invention and wheeled suspension traveling gear and supporting leg body connection mode also can adopt following technical proposals to realize: namely described creeper undercarriage and wheeled suspension traveling gear are installed in respectively the both sides of supporting leg body.
The switching of traveling gear is to finish by the lifting of wheeled suspension traveling gear in above-mentioned two kinds of structures.
Jacking system described in the present invention is to be made of the hydraulic ram that is connected between supporting leg body and the wheeled suspension traveling gear; Described jacking system also can form with the adjusting oil cylinder that is connected triangular in shape, upper connecting rod and lower link between the wheeled suspension traveling gear by being connected to the supporting leg body; Described jacking system can also form by being connected to the four-bar mechanism between supporting leg body and the wheeled suspension traveling gear and regulating oil cylinder, and described adjusting oil cylinder is connected between two hinges in middle part of four-bar mechanism to be horizontally disposed with mode.
Creeper undercarriage described in the present invention is installed in supporting leg body one side by the adjusting oil cylinder that vertically arranges side by side with vertical slideway, and wheeled suspension traveling gear is installed in the below of supporting leg body by jacking system.The switching of traveling gear can be finished by the lifting of wheeled suspension traveling gear or the lifting of creeper undercarriage in this structure.
Beneficial effect of the present invention is as follows:
Adopt crane support of the present invention at hoisting crane when the walking of common road conditions is logical, can drag the car load walking by wheeled suspension, realize fast walking, pivot turn, diagonal, walk crosswise, this moment, creeper undercarriage was unsettled; Hills, marshy area, etc. during abominable road conditions, wheeled suspension is unsettled, creeper undercarriage is landed drag the car load walking; Do not walk, hang when carrying operation when complete machine is fixing, open support oil cylinder, wheeled suspension and creeper undercarriage are all unsettled, finish the leveling work of car load by the support oil cylinder load-bearing and by it.
