As further improvement of the utility model, described guiding mechanism is provided with four altogether, and is distributed on the surrounding of described test instrument body 2.
Concrete principle of the present utility model is as follows:
One, during air inlet.
Regulate two position three way directional control valve, second admission gear is communicated with admission line 36, admission gear does work, by air pressure, spool 22 is pushed up to piston 12 side, be resisted against on the end face of the first boss 38 to annular retaining ring 40, after this, the second admission gear pressurize or lasting voltage supply, and remain in a rational scope;
Now, air admission hole 46 is communicated with annular groove 44 and hollow passageway 24, first admission gear acting, gas enters in the second chamber 20 by the hole of above-mentioned connection, groove and passage, this air pressure is less than the pressure that the second admission gear provides, and therefore will promote piston 12 and do work, and piston 12 drives piston rod 14 to move upward, thus driving cylinder arm 8 to move upward, hoistable platform 4 rises.
Two, during exhaust.
First admission gear stops doing power;
Gas outlet is communicated with admission line 36;
Piston 12, piston rod 14 and the weight be arranged on piston rod 14 move downward under gravity, gas below compression piston 12, thus band movable valve plug 22 moves downward, open to vent port 26, the unnecessary gas of major part is discharged by vent port 26, another part gas is discharged by the above-mentioned gas outlet be communicated with draft tube, realizes Quick air-discharge with this, thus piston rod 14 drives cylinder arm 8 to move downward together with hoistable platform 4.
(1) cylinder arm 8 of the present utility model is provided with two chambers, the motion of cylinder is divided into two parts and relatively independent between two parts, this mode one can shorten the stroke of cylinder, and second can realize Quick air-discharge, substantially increases the hoisting depth of cylinder and promotes frequency;
(2) the second admission gear is set, by admission line 36, for piston 12 motion in cylinder body provides power;
(3) annular groove 44 is set, and the first through hole be communicated with column-like paths 42 is provided with in the circumference of annular groove 44, because in the process that spool 22 is elevated, the circumferential degree of freedom of spool 22 is limited, and therefore it can produce certain rotation unavoidably, if be only that the mode of passing hole to hole connects with air admission hole 46, situation about cannot aim at can be there is, cause column-like paths 42 cannot air inlet, and adopt said structure, effectively can prevent the generation of this situation;
(4) guide piece is set, the effect of a guiding can be played when hoistable platform 4 moves, improve the degree of accuracy of elevating movement;
(5) regulated the height and position of block 35 by Stroke Control post 32, control the height that hoistable platform 4 promotes.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
