The suspension frame is a key core component of the magnetic suspension vehicle, is equivalent to a bogie of a wheel-track vehicle, and is mainly used for suspending a train and bearing the weight of the vehicle body. The existing magnetic suspension vehicle is generally designed with 4-5 suspension frames which are arranged compactly in the longitudinal direction. The module assembly is the skeleton of suspension frame, and the slip table is the main part that suspension frame and automobile body are connected, and the slip table is installed in the automobile body bottom, is equipped with the air spring between slip table and the module assembly. Meanwhile, in order to provide mounting interfaces for other components and prevent the vehicle from derailing to the maximum extent, the module assembly is provided with a C-shaped supporting arm, and the whole suspension frame forms a special encircling track structure.
As shown in fig. 1, the track of the existing magnetic levitation vehicle is an F-track 16, and the magnetic levitation vehicle is overhauled on the F-track 16, and the whole vehicle is often lifted during overhauling, but due to the rail surrounding structure of the magnetic levitation vehicle, if the vehicle body 1 is directly and vertically lifted, the trailing arm 5 interferes with the F-track 16, and the vehicle cannot be lifted. At present, the method is adopted that all parts below a sliding table of the suspension frame must be disassembled, a special tool is installed at the bottom of a vehicle body, the tool is lifted by a crane, the vehicle body is lifted, and the suspension frame and the vehicle body 1 are assembled again after all parts of the vehicle are overhauled, so that the overhauling efficiency of the vehicle is greatly influenced.
In addition, the directional terms referred to in this application are defined, and in the field of rail vehicles, there are three directions that are generally recognized by a skilled person:
vertical direction: vertically to the direction of the rail surface.
Longitudinal direction: along the direction of the track.
Transverse: horizontally perpendicular to the direction of the track.
Disclosure of Invention
Aiming at the problems, the invention aims to provide a magnetic levitation vehicle hoisting structure and a magnetic levitation vehicle maintenance system which are convenient and efficient to maintain.
The technical scheme for solving the problems is as follows: the utility model provides a maglev vehicle lifts by crane structure, is including setting up the lifting rope between bottom of car body slip table and module assembly tip, and the lifting rope upper end can be dismantled with the slip table and be connected, the lifting rope lower extreme can be dismantled with the trailing arm of module assembly tip position and be connected.
In traditional maglev vehicles, due to the unique design of surrounding rails of a suspension frame, all parts below a sliding table are required to be disassembled before lifting the vehicles, so that the requirement of connection between the sliding table and module assembly is eliminated, and a lifting structure is not designed. The design of present case realizes that automobile body and suspension frame lift by crane together, improves maintenance efficiency, consequently need design one set and can be connected automobile body and suspension frame to can lift by crane the structure of atress. The lifting structure of the scheme can realize the connection of the vehicle body and the suspension frame. Specifically, the vehicle body is connected with the sliding table, and the sliding table is assembled and connected with the module through a hoisting structure.
Specifically, a through hole is formed in the sliding table from top to bottom, a threaded sleeve is arranged at the bottom of the through hole, a suspension bolt is arranged in the through hole, and the suspension bolt penetrates through the through hole and is fastened with the upper end of the threaded sleeve;
the lower end of the screw sleeve is provided with a dovetail groove which is communicated along the direction vertical to the axis of the screw sleeve, and the upper end of the dovetail groove is wide and the lower end of the dovetail groove is narrow;
the upper end of the lifting rope is fixedly connected with an inverted trapezoidal clamping piece which can be matched with the dovetail groove, the clamping piece is clamped into the dovetail groove from one side of the dovetail groove, pressing plates which can plug the clamping piece are arranged on two sides of the dovetail groove, and the pressing plates are fixedly connected with the threaded sleeve.
A series of designs such as suspension bolt, swivel nut, lifting rope all are for the dismouting hoisting structure is more convenient to and connect more firmly.
Furthermore, a hanging ring is fixedly arranged at the lower end of the hanging rope and is connected with the supporting arm at the end part of the module assembly through a fastener.
Because the pretightening force of the threaded sleeve and the suspension bolt is very large, a socket wrench is needed, and an outer hexagonal boss matched with the socket wrench is arranged in the middle of the threaded sleeve.
Furthermore, a regulating gasket with a central hole is arranged at the bottom of the through hole and tightly attached to the sliding table, and the lower end of the suspension bolt penetrates through the central hole of the regulating gasket and is fastened with the threaded sleeve.
Furthermore, a counter bore with the aperture larger than that of the through hole is formed in the top of the through hole, at least two opposite surfaces of the inner wall of the counter bore are planes, the suspension bolt is an outer hexagon bolt, the bolt head is placed into the counter bore, and two surfaces of the hexagon surface of the bolt head are attached to the planes of the inner wall of the counter bore.
The counter bore is used for preventing the suspension bolt from rotating when the suspension bolt is fastened with the threaded sleeve.
The sliding table is a movable sliding table or a fixed sliding table.
Correspondingly, the invention also provides a magnetic suspension vehicle maintenance system, wherein the magnetic suspension vehicle comprises supporting wheels, module assemblies, C-shaped supporting arms, maintenance tracks and the magnetic suspension vehicle hoisting structure, and the hoisting structure is arranged at the longitudinal end part of each module assembly;

the support wheels can roll along the plane rails.
The maintenance track that the magnetism suspension vehicle overhauld usefulness has been exclusively used in the pioneering design of above-mentioned scheme, and traditional technique overhauls and all directly goes on the F rail, has the defect that the background art mentioned. The improved scheme is that the supporting wheels fall down, the engineering vehicle or the manual work is used for pushing the magnetic suspension vehicle into the plane rail, and the plane rail is not provided with the part of the F rail extending into the cavity of the C-shaped supporting arm, so that the problem of F rail interference does not exist when the vehicle is integrally lifted, and the precondition that the vehicle can be directly lifted without disassembling all parts below the sliding table of the suspension frame is created. And the newly designed hoisting structure (the vehicle body is connected with the sliding table, and the sliding table is connected with the module through the hoisting structure) is matched, so that the vehicle body and the suspension frame can be hoisted at one time under the condition of not dismounting any part, and the overhaul is more convenient. If the lifting structure is not designed, the integral lifting cannot be carried out at one time because the suspension frame and the vehicle body are not reliably connected. And in the normal running process of the vehicle, the hoisting structure is carried with the vehicle.
Preferably, the top of the plane rail and one end far away from the bracket arm are provided with limiting bulges. The limiting bulge is used for preventing the support wheel from derailing.
According to the invention, through stable and reliable lifting structure design and track improvement, the vehicle body and the suspension frame can be lifted at one time under the condition of not dismounting any part, so that the maintenance efficiency is improved. The hoisting structure is convenient to disassemble and assemble, and is stable and reliable.
