Description of drawings of the present invention is as follows.
Fig. 1 is structural representation of the present invention.
Fig. 2 is Fig. 1 plan view.
Among the figure: 1. cabinet; 2. piston; 3. guiding stay cord; 4. heavily cut or polish jade with an emery wheel; 5. the first static pulley; 6. the second static pulley; 7. the 3rd static pulley; 8. crossbeam; 9. hydraulic seal layer; 10. intermediate support truss; 11. upper support truss; 12. lower support truss.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Such as Fig. 1, shown in Figure 2, a kind of car type gas chamber piston levelling device, it includes the upper levelling gear that is installed in cabinet 1 upper end and is connected with piston 2 upper-end surfaces, upper levelling gear includes a plurality of upper leveling units, it also includes the lower levelling gear that is installed in cabinet 1 lower end and is connected with piston 2 lower end surfaces, lower levelling gear includes a plurality of lower leveling unit leveling units, lower leveling unit includes the sheave block that is fixed on the cabinet 1, guide stay cord 3 and heavily cut or polish jade with an emery wheel 4, guiding stay cord 3 one ends are fixed on piston 2 lower end surfaces, the other end passes sheave block and heavily cuts or polish jade with an emery wheel 4 and be connected, to heavily cut or polish jade with an emery wheel 4 is hung in the air, lower leveling unit is identical with upper leveling element number, the guiding stay cord 3 of each lower leveling unit the immovable point on the piston 2 all with one on the immovable point of leveling unit on piston 2 corresponding.
The present invention adopts the working method of simultaneously leveling of upper and lower levelling gear, when piston 2 occurs tilting, the guiding stay cord 3 of piston 2 tops that the upper-end surface horizontal position is lower is in tensioned state, provide a lifting force that makes progress to lower, piston 2 position, lower, piston 2 position is promoted, reach the purpose of leveling, but this guiding stay cord 3 can produce one simultaneously along the horizontal component of the higher direction in piston 2 upper-end surfaces; The below guiding stay cord 3 of the piston 2 that the lower end surface is higher is in tensioned state, provide a downward pulling force to position, piston 2 lower end surface higher position, piston 2 position higher positions are descended, reach the purpose of leveling, simultaneously this guiding stay cord 3 can produce simultaneously one along piston 2 lower end surface lower ones to horizontal component, the moment of this component is just in time opposite with the moment that piston 2 upper-end surfaces guiding stay cord 3 produces, cancel out each other, avoid 2 pairs of cabinet 1 inwalls of piston to clash into, safer under the high-pressure work pattern.
Owing to be cancelling out each other of horizontal component in the nuclear of the present invention, so upper leveling unit is essential identical with lower leveling element number, and immovable point is corresponding, immovable point has determined the direction of horizontal component, when piston 2 run-off the straight, the horizontal component that upper leveling unit produces will offset with the horizontal component that lower leveling unit produces, and the immovable point of the upper leveling unit of generally cancelling out each other, lower leveling unit and cabinet 1 center of circle are positioned on the straight line.The pulling force of guiding stay cord 3 produces by heavily cutting or polish jade with an emery wheel 4, heavily cuts or polish jade with an emery wheel the pulling force that 4 pairs of guiding stay cords 3 produce vertically downward, and guiding stay cord 3 is converted to lower leveling unit to the lower pulling force of piston 2 by sheave block with this pulling force.
Upper leveling unit includes the static pulley that is installed on the cabinet 1 and passes the guiding stay cord 3 of static pulley, and guiding stay cord 3 one ends are connected with piston 2, the other end with heavily cut or polish jade with an emery wheel 4 and be connected.Heavily cut or polish jade with an emery wheel 4 gravity is converted to upper leveling unit guides stay cord by static pulley lifting force.
Sheave block can include three static pulley, and the first static pulley 5 is installed in cabinet 1 bottom, and the second static pulley 6 is installed in cabinet 1 top, and the 3rd static pulley 7 is installed on the cabinet 1 top crossbeam 8, the same heavy stone roller 4 of lower leveling units shared.So arrange and to guide all guiding stay cords into the cabinet top, be convenient to cabling, solved the in disorder problem of guiding stay cord, more convenient operation.
Sheave block also can include two static pulley, and two static pulley are installed in the cabinet bottom one on the other.So arrange simple in structurely, be convenient to safeguard.
Certainly sheave block can also be other structural type, changes according to field condition.
Lower leveling unit can be two, and two lower leveling units are evenly distributed on cabinet 1 surface.Lower leveling unit further is four, eight or a plurality of, be evenly distributed on the cabinet 1, but need to be corresponding one by one with upper leveling unit.
Pass cabinet 1 position at cabinet 1 bottom guiding stay cord 3 and be provided with hydraulic seal layer 9.The sealability of gas cabinet is extremely important, because the guiding stay cord need to pass the cabinet surface, will inevitably produce the slit, and the hydraulic seal layer can effectively solve sealing problem, can certainly use other forms to seal.
Be provided with intermediate support truss 10 at piston 2.Because in the process of leveling, guiding stay cord 3 can provide pulling force to piston 2, and this pulling force acts on the point of piston 2, piston 2 discontinuity produce distortion easily, affect piston 2 normal operations, the effect of intermediate support truss 10 is exactly the intensity of strengthening piston 2, avoids distortion.In like manner, can also be provided with upper and lower sub-truss 10,11 at piston 2 upper/lower terminal faces.
Guiding stay cord 3 can be wire rope, also can be other high strength cords.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present invention.
