Push rod 410, the lower end of this cam follower 410 can coordinate with drive shaft 41 overhead cam 412 and offsets, in the rotation of drive shaft 41
Under by with the coordinating of cam 412, cam follower 410 can periodically move up and down, and then controls the first stop valve 451 and the
Two stop valves 471 carry out the most alternately opening/closing.
In the double stroke piston hydraulic pressure loading climbing storey wheeled instrument that above-described embodiment provides, on the one hand drive shaft can drive power transmission shaft to enter
Row rotates, it is achieved the up/down stair function of stairs-mover, on the other hand cam follower can also be driven to move up and down, and controls
Alternately opening/closing between the first stop valve and the second stop valve, and then control first piston hydraulic cylinder and the second piston liquid
Hydraulic oil flow between cylinder pressure to, the specific works process of this stairs-mover is: start oil pump, the hydraulic oil in fuel tank is pumped into
In the cylinder body of the second piston hydraulic cylinder, under the pressure-driven of hydraulic oil, the second piston rod in the second piston hydraulic cylinder is downward
Mobile, see Fig. 3, owing to the second piston rod and the second rocking bar are rotationally connected, the second rocking bar therefore can be driven to move down, and then
Drive drive shaft to rotate, and owing to the first rocking bar and the second rocking bar are oppositely arranged, therefore, move down band at the second rocking bar
While dynamic drive shaft turns, the second rocking bar can move up along with the rotation of drive shaft, and then drive and to be rotationally connected with it
First piston bar in first piston hydraulic cylinder moves up, by the hydraulic oil in first piston hydraulic cylinder along the second pipeline stream
Entering in fuel tank, then be transported in the cylinder body of the second piston hydraulic cylinder by oil pump, now the first stop valve on the first pipeline is closed,
And on the second pipeline second stop valve open, when the piston rod in the second piston hydraulic cylinder move down move to extreme position time,
Piston rod in corresponding first piston hydraulic cylinder also on move on to extreme position, the projection in drive shaft by cam follower top to the highest
Position, now drive shaft runs half cycle just, and when under the effect of inertia, drive shaft is rotated further, push rod moves down, and controls
The first stop valve on first pipeline is opened, and the second stop valve on the second pipeline is closed, now, in the second piston hydraulic cylinder
Hydraulic oil is flowed in first piston hydraulic cylinder along the first pipeline, and the first piston bar of correspondence moves down, the second piston
Bar moves up, and drives drive shaft to carry out the rotation of lower half, reciprocal with this, it is achieved the lasting rotation of drive shaft, and then drives
The lasting rotation of power transmission shaft, drives the star wheels index at two ends, completes the up/down stair function of stairs-mover.
Wherein, the drive connection mode between drive shaft 41 and power transmission shaft 2 can select multiple, and such as conveyer belt connects
Deng, seeing Fig. 1, in the present embodiment, drive shaft 41 and power transmission shaft 2 are by intermeshing first gear 414 and the second gear 21
Drive connection；And first gear 414 fixed cover be loaded in described drive shaft 41, the second gear 21 fixed cover is loaded on described power transmission shaft
On 2, it is preferable that the first gear 414 fixed cover is loaded on the midpoint of drive shaft 41, the second gear 21 fixed cover is loaded on power transmission shaft 2
Midpoint.
Preferably, the radius ratio of the first gear 414 and the second gear 21 is 2:3, and then guarantees to pass when drive shaft rotates a circle
Moving axis completes the rotary motion of 120 °, makes stairs-mover entirety creep a step play certain transition and steadily act on.
Wherein, the first rocking bar 411 and the second rocking bar 413 are symmetrical arranged along the midpoint of drive shaft 41 in drive shaft 41, make
Stairs-mover receives the driving force of equilibrium, improves the stationarity of stairs-mover up/down stair.
For the rolling of stairs-mover discontinuity, for improving its stationarity gone downstairs and safety, in the present embodiment, at fuel tank
Precursor overflow valve it is provided with on 46, when needs carry out upper and lower building operation, first oil pump switch, then make at precursor overflow valve
In normally open, can be provided with at the handle position of stairs-mover for controlling the control handle that precursor overflow valve is opened/closed.
In operation process upstairs, run into when needing power transmission shaft rotary work, control precursor overflow valve by control handle and close
Close, make the first piston hydraulic cylinder being interconnected, the second piston hydraulic cylinder, fuel tank and multiple pipe-line system start supercharging, enter
And complete the cycle spinning movement climbed needed for building, after completing to work the most upstairs, can open precursor overflow valve carries out off-load,
Ensure that during horizontal movement, hydraulic system not drive shaft rotates.
In like manner, in operation process downstairs, the first piston hydraulic cylinder that makes to be interconnected, the second piston hydraulic cylinder, fuel tank
And multiple pipe-line system is the most in running order, precursor overflow valve by control handle control, scalable control during different loads
Knob processed, control the first piston hydraulic cylinder, the second piston hydraulic cylinder, fuel tank and the multiple pipe-line system supercharging that are interconnected with
No, make stairs-mover shaft portion during downstairs produce enough resistances, slow down impact, it is achieved go downstairs safely and smoothly.
