Description
Technical field
The invention belongs to field of track traffic, and in particular to a kind of maglev vehicle hoisting structure and maglev vehicle maintenance system
System.
Background technique
Suspension rack is the key core component of maglev vehicle, is equivalent to the bogie of wheel track vehicle, and main function is outstanding
Floating train and bearing body weight.Existing maglev vehicle generally is configured with the 4-5 suspension racks for being longitudinally compact arrangement.Module assembly
It is the skeleton of suspension rack, slide unit is the main component that suspension rack is connect with car body, and slide unit is mounted on vehicle bottom, slide unit and module
Empty spring is equipped between assembly.Meanwhile in order to provide installation interface to other component and prevent vehicle derailing to greatest extent, module dress
It is equipped with C-shaped trailing arm, entire suspension rack, which is formed, special encircles track structure.
As shown in Figure 1, the track of current maglev vehicle is F rail 16, maglev vehicle is also enterprising in F rail 16 when overhauling
Row, when maintenance, generally requires lifting vehicle, but encircles rail structure due to maglev vehicle, if directly vertical lifting car body 1, meeting
Cause trailing arm 5 and F rail to interfere 16, can not lift by crane.Currently used way is must to dismantle all components of suspension rack slide unit or less,
Special tooling is installed in vehicle bottom, with crane hoisting tool, realizes car body lifting, is weighed again after completing all component inspections of vehicle
Newly suspension rack and car body 1 are assembled, this leverages the overhaul efficiency of vehicle.
In addition, being defined to the direction vocabulary being previously mentioned in this case, in track vehicular field, technical staff usually recognizes
There are three types of fixed directions:
It is vertical: vertically perpendicular to the direction of rail level.
It is longitudinal: along the direction of track.
Laterally: horizontal vertical is in the direction of track.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of maglev vehicle hoisting structure for overhauling convenience and high-efficiency and magnetic float vehicle
Examination and repair system.
The technical solution that the present invention solves the problems, such as is: a kind of maglev vehicle hoisting structure, including is set to vehicle bottom and slides
Lifting rope between platform and module assembly end, lifting rope upper end and slide unit be detachably connected, lifting rope lower end and module assembly side position
The trailing arm set is detachably connected.
In traditional maglev vehicle, Track desigh is encircled since suspension rack is distinctive, it must will be below slide unit before Vehicles Lifting
All component disassemblies, therefore there is no the demand of connection between slide unit and module assembly, also without design hoisting structure.The structure of this case
Think of be realize car body lifted by crane together with suspension rack, improve overhaul efficiency, it is therefore desirable to design it is a set of can be by car body and suspension rack
Connection, and the structure of stress can be lifted by crane.The hoisting structure of above scheme can be realized the connection of car body and suspension rack.Specifically
Car body is connect with slide unit, slide unit passes through hoisting structure and module assembly connection.
Specifically, offering top-down through-hole on slide unit, via bottoms are provided with swivel nut, and suspension is provided in through-hole
Bolt, Hanging bolt passes through through-hole and swivel nut upper end fastens；
Swivel nut lower end is equipped with dovetail groove, and the dovetail groove is penetrated through along perpendicular to swivel nut axis direction, and dovetail groove upper end is wide, lower end
It is narrow；
The inverted trapezoidal holding firmware that can cooperate with dovetail groove is fixedly connected in lifting rope upper end, the holding firmware is from dovetail groove side card
Enter in dovetail groove, the pressing plate that holding firmware can be blocked is equipped in dovetail groove two sides, pressing plate is fixedly connected with swivel nut.
It is more convenient that a series of designs such as Hanging bolt, swivel nut, lifting rope are provided to dismounting hoisting structure, and connects more steady
Gu.
Further, the lifting rope lower end is fixed with hanging ring, and the hanging ring passes through fastener and module assembly side position
The trailing arm connection set.
Since the pretightning force of swivel nut and Hanging bolt is very big, need to use box spanner, therefore being equipped in the middle part of swivel nut can
With the outer-hexagonal boss of box spanner cooperation.
Further, it is equipped with the band centre bore being close to slide unit at via bottoms position and adjusts gasket, the suspension spiral shell
Bolt lower end passes through the centre bore of adjustment gasket and swivel nut fastens.
Further, it is equipped with the counterbore that aperture is greater than through-hole in via top, at least there are two opposite for the counterbore inner wall
Face be plane, the Hanging bolt is outer-hexagonal bolt, and bolt head is placed in counterbore, and two in the hex surface of bolt head
Face is bonded with the inner wall plane of counterbore.
When the effect of counterbore is so that Hanging bolt and swivel nut fasten, Hanging bolt is avoided to rotate.
The slide unit is movable slide unit or fixed slide unit.
Correspondingly, the present invention also provides a kind of maglev vehicle examination and repair system, maglev vehicle includes support wheel, module assembly,
Module assembly is equipped with C-shaped trailing arm, further includes maintenance track and above-mentioned maglev vehicle hoisting structure, and the hoisting structure exists
The longitudinal end of each module assembly has setting；
The maintenance track includes sleeper, the plane rail for being set to sleeper top two sides；It is plane at the top of the plane rail, and flat
The transverse end of face rail and the transverse end of sleeper are concordant, and the type that plane rail transverse end does not protrude into C-shaped trailing arm is intracavitary；
The support wheel can be rolled along plane rail.
Above scheme initiative devises the maintenance track for being exclusively used in maglev vehicle maintenance, when traditional technology overhauls all
It is directly carried out on F rail, haves the defects that background technique is previously mentioned.Improved scheme is utilized by falling support wheel
Maglev vehicle is manually pushed into plane rail by engineering truck, since plane rail is without the portion of the type chamber for protruding into C-shaped trailing arm of F rail
Point, therefore F rail interference problem is just not present when integral lifting vehicle, all portions of suspension rack slide unit or less can not be dismantled by creating
Part and the precondition directly lifted by crane.Cooperating newly-designed hoisting structure again, (car body is connect with slide unit, slide unit passes through hoisting structure
With module assembly connection), disposably car body and suspension rack can be sling in the case where not dismantling any part, so that inspection
It repairs more convenient.If not designing this hoisting structure, just can not disposable integral lifting because suspension rack and car body may not be used
By connection.In vehicle normal course of operation, hoisting structure is with vehicle.
Preferably, one end at the top of plane rail, far from trailing arm is equipped with retention bead.Retention bead is for preventing support wheel de-
Rail.
The present invention allows to do not dismantling any part by reliable and stable hoisting structure design and improvement of orbit
In the case of, disposably car body and suspension rack are sling, improve overhaul efficiency.Hoisting structure is convenient for disassembly and assembly, reliable and stable.
