Detailed description of the invention
As shown in Figure 1, a kind of running mechanism of middle low-speed maglev train, comprise draw beam 1 and linear electric motors 2, linear electric motors 2 are arranged on draw beam 1 by vertical lift registration device, and carry out lifting by vertical lift registration device, to adjust the spacing H between linear electric motors 2 and F rail 3 upper surfaces, vertical lift registration device comprises lifting mechanism and linear electric motors mount pad 4, lifting mechanism is arranged on draw beam 1, lifting mechanism is connected with linear electric motors mount pad 4, and linear electric motors 2 are arranged on the below of linear electric motors mount pad 4.Linear electric motors 2 carry out perpendicular positioning by 3~5 groups of lifting mechanisms that longitudinally arrange, and every group of lifting mechanism is made up of the lifting mechanism of two lateral arrangement.
Lifting mechanism is hydraulic actuating cylinder 6.Between hydraulic actuating cylinder 6 and draw beam 1, adopt flange connection or bearing connection mode to be fixed.Flange connect has simple in structure, the advantages such as easy processing and easily assembling, therefore hydraulic actuating cylinder 6 can be installed in hydraulic actuating cylinder sleeve 9, hydraulic actuating cylinder sleeve 9 is installed in the hydraulic actuating cylinder mounting hole on draw beam 1, on hydraulic actuating cylinder sleeve 9, there is flange, on flange, pad is adjusted pad 8, adjusting pad 8 and flange is fixed on draw beam 1 by tightening screw 7, between hydraulic actuating cylinder 6 and linear electric motors mount pad 4, adopt rubber arthrosis 5 to connect, be conducive to the high-frequency vibration that isolation comes from linear electric motors 2, screw thread has been designed in linear electric motors mount pad 4 lower ends, the screw hanging with linear electric motors coordinates, be convenient to the assembling of linear electric motors 2.
Hydraulic actuating cylinder 6 is entered and is promoted piston after oil cylinder and piston rod carries out corresponding actions by check valve by hydraulic oil, because hydraulic oil pressure shrinkage is larger, the feature such as therefore hydraulic actuating cylinder 6 has simple in structure, High power output, stable and reliable for performance, working service facilitates, have wide range of applications.The vertical lift registration device that employing hydraulic actuating cylinder 6 is power element is in the time that maglev vehicle lands, and hydraulic actuating cylinder 6 releases, make linear electric motors 2 and F rail 3 upper surface spacing H keep 3~5mm; When maglev vehicle suspends, hydraulic actuating cylinder 6 start of pressurizeing, makes the spacing H between linear electric motors 2 and F rail 3 upper surfaces still remain on 3~5mm, compares the vertical registration device of existing fixed type, the spacing H that can effectively reduce linear electric motors 2 and F rail 3 upper surfaces, effectively improves electrical efficiency.In addition,, for preventing that linear electric motors 2 from touching F rail 3, at linear electric motors, vertical anti-contact skid is installed for 2 times.
