Description

Maglev vehicle underframe mounting structure

Technical field

The present invention relates to magnetic-levitation train technical field, and in particular to a kind of maglev vehicle underframe mounting structure.

Background technology

The maglev vehicle underframe mounting structure of prior art, more using tower structure.This structure as shown in Figure 1, The framework being welded to form by the intersecting framework beam of crossbeam 19 and longeron 21, in the frame between inlay aluminium honeycomb aluminum floor 22.Two groups 20 points of expansion crosstie is left and right two parts, and all chassis apparatus are hanging on crossbeam.The shortcoming of this scheme be car body rigidity compared with It is weak, car body soundproof effect is bad, and part is more, and welding capacity is big etc., and because expansion crosstie is divided right and left, the flatness of its lower surface It is difficult to ensure with linearity.To solve these problems, the Chinese patent application of Application No. CN201310380606.8 is proposed A kind of levitation train vehicle body bottom frame structure.This structure is integral type expansion crosstie welding structure, mainly by floor long, underframe Side bar, end carriage, six expansion crossties are welded.Although this scheme overcomes the one of said frame formula structure to a certain extent A little shortcomings, but expansion crosstie, using complicated welding structure, part is more, causes construction weight to increase, the overall structure fatigue longevity Life is also difficult to ensure that;The integral planar degree and guide groove linearity of six groups of expansion crossties are difficult to ensure that, it is necessary to complete laggard in welding The overall machining of row, processing capacity is big, high to equipment frock requirement, and manufacturing cost is huge.Existing two kinds of structures all can only be by equipment It is hung directly under floor, the vibrations of equipment, noise, heat will directly pass through the incoming guest room in floor, the direct closely plate of equipment, It is unfavorable for equipment wiring, radiating and overhauls.

The content of the invention

The present invention provides a kind of maglev vehicle underframe mounting structure, simplifies structure, increases intensity, convenient to install.

The technical solution adopted in the present invention is:A kind of maglev vehicle underframe mounting structure, by side bar, base plate, end carriage, holds Carry mounting rail, equipment mounting rail, buttress brace composition, it is characterised in that base plate is to be welded to connect with side bar and end carriage, base plate lower section It is provided with for installing buttress brace, wire casing, pipeline and the chute of suspension controller, top is provided with the width for pre-buried floor mounting seat Chute, the position for corresponding to each suspension rack sets a pair of carrying mounting rails, and the top of side bar is connected with vehicle body side wall, side bar Lower section is provided with chute, is connected with mounting rail is carried by sliding block matching fastener, and buttress brace is arranged on base plate and is held by bolt Carry between mounting rail, equipment mounting rail is bolted on mounting rail is carried, end bearing mounting rail is by bolt and end Mounting blocks connection on portion's suspension rack slide unit, the pre-buried screw-thread bush in middle part carrier bar lower section is suspended by bolt installed in middle part On the guide rail of frame guide rail formula slide unit.

In order to the purpose of the present invention is better achieved, the side bar uses the hollow extruded aluminium section of big cross section, will be following non- The bottom one layer of rectangle mold cavity for carrying mounting rail connecting portion is machined away.

In order to the purpose of the present invention is better achieved, the base plate is lap weld with the weld seam form of end carriage, side bar.

In order to the purpose of the present invention is better achieved, the section of the sliding block is Qian shape structure, and bottom is provided with and may pass through spiral shell The through hole of bolt.

The beneficial effects of the invention are as follows:Simple structure, number of parts is few, lightweight, with high intensity.Using bolt with it is outstanding Scaffold slide unit is connected, and does not have welding deformation, will not produce potential safety hazard because of weld fatigue failure.It is easy for installation flexible, to system Making error has adjustment capability, it is not necessary to carry out overall machining because of installation accuracy requirement, cost-effective.Easily inspection Repair, structure type beneficial to equipment cooling and to greatest extent to guest room sound insulation, it is heat-insulated.

Specific embodiment

Invention is described further in conjunction with accompanying drawing.

Referring to Fig. 2 and Fig. 3, the maglev vehicle underframe mounting structure of the present embodiment is pacified by side bar 1, carrying mounting rail 2, equipment Dress beam 3, end carriage 4, base plate 5, buttress brace 6 are constituted.Base plate 5 is formed using the hollow extruded aluminium section welded of big cross section, and weld seam is right Welding seam.There is chute 10 lower section of base plate 5, and for installing buttress brace 6, wire casing, pipeline and suspension controller etc., mounting means is spiral shell Tether and connect.The pre-buried floor mounting seat 12 for installing guest room floor 11 in the top sipes 9 of base plate 5, in guest room floor and base plate 5 Between arrange acoustical and thermal material, effective heat-insulating and shock-absorbing noise reduction.Base plate 5 is welded to each other with end carriage 4, side bar 1, and weld seam form is to take Welding seam, is shown in Fig. 6.Side bar 1 is the important carrying force transferring part in underframe, and top is connected with vehicle body side wall (not shown), lower section It is connected with mounting rail 2 is carried, carries mounting rail 2 and formed using hollow extruded aluminium shape extrusion.Non-bearing is installed below side bar Beam connecting portion, bottom one layer of rectangle mold cavity is machined away, and on the premise of intensity is met, amplitude peak mitigates weight, together When facilitate suspension controller extract out maintenance (suspension controller is drawer-type structure), see Fig. 3.The lower section of side bar 1 is provided with chute 13, holds Carrying mounting rail 2, to connect through the matching fastener 8 of sliding block 7 coupled, and sliding block 7 is stainless steel part, and its section is Qian shape structure, bottom Portion is provided with the through hole that may pass through fastener 8, plays increase contact area, it is ensured that the effect of structural strength.Can be adjusted by pad The whole foozle and car body between, convenient and flexible installation can guarantee that the installation accuracy requirement of slide unit again, see Fig. 5.End suspends Frame slide unit 14 sets four mounting blocks 15 for being threaded hole, is connected with mounting rail 2 is carried by bolt, sees Fig. 7.Middle part suspends Frame slide unit 18 is different from end slide unit, is relative sliding structure, possesses two sections of stainless steel guide rails 16.Carry the lower section of mounting rail 2 Pre-buried screw-thread bush 17, guide rails assembling is rear on carrying mounting rail 2 to be connected with middle slide unit, and can between energy and slide unit Relative slip is produced, vehicle completes small curve negotiating, sees Fig. 8 by this mechanism.Buttress brace 6 is used to strengthen underframe mounting structure Intensity, is equally connected by screw bolts.Equipment mounting rail 3 is bolted on mounting rail 2 is carried, for the installation of equipment. After equipment is installed, space is left between top and base plate 5, facilitate the arrangement of pipeline and circuit, be also beneficial to equipment cooling.Entirely Inventive structure is simple, and part is few, lightweight, and intensity is high, bolt connection substitution welding structure, can effectively avoid weld fatigue from losing The potential safety hazard that effect is caused.
