Description
Technical field
The utility model relates to carrying transporting apparatus, refers in particular to controlled loss of weight scheme during Large heavy object high precision movement.
Background technology
When moving Large heavy object at present, often need large-scale haulage equipment to realize, when if desired carrying out retrofit or other high Precision Processing to this type objects, just to its carrying or the mobile requirement having degree of precision.But because it is bulky, the reason that especially quality is larger, traditional large-scale haulage equipment is to its operating difficulties and be difficult to the requirement reaching high precision movement.If only utilize electromagnetic force to carry out loss of weight to object, when mass of object is very large, the energy consumption of weight reducing device is larger.
Utility model content
In view of the above deficiency of prior art, the purpose of this utility model is the difficulty for high precision movement Large heavy object, provides a kind of scheme of hybrid magnets power loss of weight that utilizes to realize the high precision movement of object.
The technical solution of the utility model is:
A load-carrying transfer platform for the controlled loss of weight of hybrid magnets power, for carrying out high precision displacement to large and heavy objects.Having that track 2 and its top is placed in can along the U-shaped load carrying platform 1 of its surface sliding on track 2; Track 2 is provided with a magnetic force generating mechanism below and between U-shaped load carrying platform bottom, this magnetic force generating mechanism is formed relative to two electromagnet of load carrying platform rear and front end and two permanent magnets be placed in respectively on two electromagnet by having to be symmetrically distributed in, four magnet coils are wrapped on four U-shaped posts of two electromagnet respectively, and magnetic force generating mechanism produces the suction of U-shaped load carrying platform bottom upwards adhesive; Four pressure sensors are arranged on load carrying platform, to be symmetrically distributed in bottom load carrying platform all around on four points; One for realizing forming with sensor and magnet coil respectively the control unit 7 that four magnet coil electricity control being electrically connected by reading four pressure sensor signals; Being provided with at electromagnet medium position avoids permanent magnet to occur the dead boss 6 of anti-suction that track is inhaled dead situation and occurred when producing relative motion with track.
Further, described track 2 is trapezoidal with the contact surface on U-shaped load carrying platform 1 top, and namely track 2 has inverted trapezoidal groove, and U-shaped load carrying platform 1 top has trapezoid convex.
Permanent magnet 3 and electromagnet 4 produce suction in order to offset the gravity of mobile object and load carrying platform with rail interaction.
The object 9 of required movement is placed in load carrying platform top.Permanent magnet provides larger suction to overcome the gravity of required mobile object and load carrying platform, and its suction is slightly less than gravity.
Like this, the electric current flowing through magnet coil is less, is only applied to the malconformation of track upward pressure in order to balanced load platform.Its malconformation is detected by pressure sensor, when the detected value of four sensors is not of uniform size cause time, the size flowing through magnet coil 5 electric current is regulated by control unit 7, thus make the suction of four electromagnet different, finally make the detected value of four sensors identical, equal a less fixed value, thus reach balanced load platform and be applied to the unbalanced object of track upward pressure, when avoiding mobile object, occur the situation nodded in left and right or front and back.
Load carrying platform is to the pressure of track about close to 0 but when being not equal to 0, namely hybrid magnets suction is less than the gravity of load carrying platform and mobile object, load carrying platform can be pressed in orbit completely, and platform and interorbital gap are zero, thus there will not be up-down vibration when ensure that mobile object.In addition, because inverted trapezoidal groove is arranged at track top, ensure that load carrying platform band animal body there will not be when moving and swing.
The effect of the dead boss of anti-suction be for load carrying platform upwards relative motion time, avoid permanent magnet and track to inhale dead situation and occur.
Owing to there will not be the situation of bobbing and weaving and nodding when the program ensure that object moves all around, thus ensure that the high precision movement of required mobile object by track alignment.
Accompanying drawing explanation

Detailed description of the invention
Two permanent magnets are identical with electromagnet structure, and symmetry is arranged on load carrying platform rear and front end.Permanent magnet is rectangular configuration, and electromagnet is U-shaped, and four magnet coils 5 are wound around on four U-shaped posts of electromagnet respectively, and the number of turn of coil is identical with coiling direction.
Four pressure sensor 8 parameters are identical, and symmetry to be arranged on bottom load carrying platform all around on four points, and Fig. 1 is seen in installation site.
Permanent magnet provides larger suction to overcome the gravity of required mobile object and load carrying platform, and its suction is slightly less than gravity.Such as the weight of required mobile object and load carrying platform is 2 tons altogether, can design the suction that permanent magnet provides 1.9 tons.
The down suction that the dead boss of anti-suction leaves the right or normal track is much smaller than permanent magnet and interorbital down suction, when there is the situation of upward movement in load carrying platform, first the dead boss of anti-suction withstands on rail base, stops the further upward movement of platform, thus avoids permanent magnet and track and inhale dead situation and occur.
When object sole mass is uneven or load carrying platform band animal body move steadily time, the pressure that load carrying platform applies in orbit can unbalanced, thus load carrying platform there will be about or the front and back situation of nodding.For avoiding this situation to occur, the suction by electromagnet regulates.When load carrying platform be applied to track upward pressure unbalanced time, the force value meeting difference that four pressure sensors detect, four detected pressure values are sent into magnet coil control unit, the size flowing through electromagnet coil current is regulated by control unit, thus make the suction of four electromagnet different, the force value finally making four sensors detect is identical, equal a less fixed value, as 0.1kg, so just, the pressure uniform distribution that ensure that load carrying platform in orbit, avoids the situation that when load carrying platform moves, appearance is nodded all around.
The power applied in orbit due to load carrying platform is not equal to 0, and this just ensure that load carrying platform falls in orbit completely, and by the restriction of track inverted trapezoidal structure, load carrying platform there will not be the situation of left and right downward shift.
Permanent magnet provides the suction of mobile object and load carrying platform total weight 95%, electromagnet needs the power that provides less, only be applied to the malconformation of track upward pressure in order to balanced load platform, therefore the electric current flowing through magnet coil is less, thus greatly reduces the energy consumption of weight reducing device.
