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.
