Of course, the effect of raising the height of the upper car body 4 can also be achieved by increasing the height of the underframe 2. Therefore, the scheme is suitable for construction vehicles with low chassis, and is particularly suitable for rotary drilling rigs.
According to the technical scheme, the heightening mechanism is arranged between the underframe and the slewing bearing, so that the height of the upper vehicle body is raised, the upper vehicle body is higher than the water surface, and the construction vehicle can adapt to construction in a deeper water area, so that the operation capacity of the construction vehicle is enhanced; the scheme is particularly suitable for the rotary drilling rig.
Specifically, as shown in fig. 1, the heightening mechanism includes: supporting the cartridge 11. It will be understood that the support cylinder 11 has a hollow through structure so as to serve as a passage for laying components connected between the running gear 1 and the upper vehicle body 4. In this scheme, adopt a support section of thick bamboo 11 as increasing the mechanism, have simple structure, support characteristics such as intensity are big. Of course, support posts may also be used as the heightening mechanism. Further, in order to adjust the height of the upper vehicle body 4, the support cylinder 11 may be designed to have a hydraulic lifting structure.
In this scheme, because last automobile body 4 is in high-order operation, in order to reduce the staff and take place unexpected risk, this needs last automobile body 4 to have protective structure, prevents that the staff from taking place high-order tumble injury, helps promoting construction vehicles's operation security.
