Six rib screwed pipes 420 and 413 combinations of hexagon screwed pipe cover can only axially move hydraulic piston 42 in compression cylinder 41, can not rotate along with hydraulic pressure screw rod 43.Hydraulic pressure screw rod 43 and 420 different being threaded of six rib screwed pipes, when making driven by shaking wheel 32 drive hydraulic pressure screw rod 43 toward the equidirectional rotation, two screw rod hydraulic compressors 40 all are with hydraulic oil output or are input into compression cylinder 41.
Clamping ball 50 and ball grooves 433 combinations; Make two mekydros 430 combine and be under pressure or can both normal rotation during pulling force; When hydraulic pressure screw rod 43 promotes itself will bear the recoil of drawing back when hydraulic piston 42 produces positive pressure; This recoil is sent on another screw rod hydraulic compressor 40 through clamping ball 50 it can not retreated, and can only promote hydraulic piston 42 hydraulic oil is imported pillar oil cylinder 240., hydraulic pressure screw rod 43 pulling hydraulic pistons 42 itself to bear progressive tractive force when producing negative pressure; This tractive force is sent on another screw rod hydraulic compressor 40 through clamping ball 50 it can not advanced, and can only spur hydraulic piston 42 hydraulic oil is sucked compression cylinder 41.
Present embodiment on even running road surface through interior lifting wheel 21, outer lifting wheel 22 or interior lifting wheel 21 with outside lifting wheel 22 mix and can both move easily; Transport trolley just can make loading compartment 10 maintenance state of equilibriums move according to the height of lifting wheel 21 in the gradient of slope adjustment and outer lifting wheel 22 when operation on ramped aisle.During present embodiment process step passage; Earlier with the headstock of transport trolley over against and push up step; Through interior lifting wheel 21 or outer lifting wheel 22 transport trolley integral body is risen; Another secondary outer lifting wheel 22 or interior lifting wheel 21 push up on the step through outer lifting wheel 22 or the interior lifting wheel 21 of wheel carrier pull bar 23 with the transport trolley front end along with transport trolley is increased to the height of step simultaneously, take turns 32 through driven by shaking simultaneously the weight of transport trolley transferred on the lifting wheel that pushes up step; Again through driven by shaking wheel 32 and wheel carrier pull bar 23 will not stress lifting wheel push up step to a new level on, so repeatable operation just can make transport trolley pass through the step passage.
In sum: the utility model solved the bigger ramped aisle of prior art hand barrow impassabitity step passage and the gradient and on ramped aisle compartment bevelled problem during operation, a kind of balanced type hand push transport trolley that can replace existing product is provided.
