Establish the end, middle and high three layers on the described base and fixedly mark time, these three aspects are the staged dislocation; Mobile lifting platform be positioned at high-rise fixedly mark time on.
The utility model is by adding two fixedly mark time layer and mobile lifting platforms at base, form structural framing, its three aspects are the staged dislocation, form the staged step of marking time, each aspect has certain width, can stand for the people, and ascend operation thus, also can stand in and carry out job execution on each aspect, when needed, each aspect can be put instrument and various spare part again.
Near the medium of air pump output can directly enter column is input to its excess-three column by the conduit connection again, and the superiors of dolly will raise automatically, reach the purpose of ascending a height.
Compressed gas is drained by blow off valve (hand push button formula check valve) during recovery, and dolly supports suspension column by spring reset, and the dolly wheel settling touch-down can move freely simultaneously.
The beneficial effects of the utility model:
The utility model promotes the piston rod stretching operation by eccentric cam, makes several piston rods move the design that forms an air pump continuously, improves the air pressure continuous output, and the equipment that has substituted the active hydraulic pump fully uses.Because dynamic medium is an air, having removed active lift car from has oil pollution and makeup oil problem with oil, will consider also during use whether the scene has power supply, and the restriction condition of all inconvenience of power lead and searching cooperation work post or the like; Its type of belt drive is to use hand variable gear, drives eccentric wheel and promotes air pump piston output pressurized air, and the power mode of transmission is to utilize eccentric inertia to borrow the power transmission, reaches the effect of getting twice the result with half the effort.
