Abstract
The present invention relates to a kind of attachment beams in combined high-speed train apparatus cabin, belong to track train technical field.Traditional equipment compartment attachment beam is a kind of aluminium alloy attachment beam of monoblock cast, and lifting lug is easy to generate fatigue fracture, and is difficult to securely be connected again with the methods of welding, can not be repaired.In view of the above problems, lifting lug is detachable the invention proposes a kind of knockdown high-speed trains cabin attachment beam, with bolt fastening in connection beam body, can be replaced at any time after fracture；Connection beam body still uses aluminum alloy materials, and detachable lifting lug material is high-strength steel, and intensity is higher, and the service life is longer.
Description
Technical field:
The present invention relates to a kind of attachment beams in combined high-speed train apparatus cabin, belong to track train technical field.
Background technique:
Many equipment of bullet train are all lifted on vehicle body bottom frame and protect in the following, being surrounded by equipment compartment, prevent sandstone, dust
Equivalent damage equipment.Equipment compartment is generally made of equipment hatchway cover, skirtboard, equipment compartment attachment beam, and equipment compartment attachment beam is equipment compartment
Frame member, by bolt fastening on vehicle body bottom frame, side cover skirtboard, bottom surface connect equipment hatchway cover, formed one it is close
The cabin closed is to protect equipment under vehicle.
Equipment compartment attachment beam is a kind of aluminium alloy attachment beam of monoblock cast, and bottom side is cast with multiple lifting lugs, equipment compartment
Cover board is bolted connection on these lifting lugs.Lifting lug bears equipment hatchway cover weight, while being also subjected to when vehicle is run
Vibration and windage bring alternating load.The bullet train speed of service is high, and alternating load caused by windage is big, and lifting lug is easy to produce
Raw fatigue fracture, and then equipment hatchway cover is caused to fall off, crisis traffic safety.Therefore, once there is lifting lug breakage problem, just must
It must on-call maintenance solution.But it since this attachment beam is aluminium alloy monoblock cast, is difficult to after lifting lug fracture with the side such as welding
Method securely in connection, can not repair again, in order to guarantee traffic safety, can only integral replacing, cause equipment compartment attachment beam using the longevity
Order low, vehicle maintenance is at high cost.This problem seriously annoyings vehicle using unit, is badly in need of solving.
In view of the above problems, dexterously being solved the invention proposes a kind of knockdown high-speed trains cabin attachment beam
Can not be repaired after traditional one piece casting type equipment compartment attachment beam lifting lug fracture, attachment beam scrap must integral replacing the problem of.
Summary of the invention:
Above-mentioned purpose of the invention is realized by the following method, as follows now in conjunction with Detailed description of the invention:
The equipment compartment attachment beam of traditional monoblock cast is shown in attached drawing 1, connects beam body 1 (1) with lifting lug 1 (2) and is
Aluminum alloy materials, and integrally casting shaping is used, the position at arrow meaning to be easily broken in actual use.
The combined high-speed train apparatus cabin attachment beam is shown in attached drawing 2, comprising in 1. connection beam bodies, 2. lifting lugs, 3.
Hex bolts.Lifting lug 2 is fastenedly connected by hexagon socket head cap screw 3 with beam body 1 is connect, and equipment compartment attachment beam is assembled into.When lifting lug 2
When being broken or needing replacing, bolt 3 only need to be unloaded, changes new lifting lug, it is good to be fastened with bolt 3, entire connection that no replacement is required
Beam.
The connection beam body 1, material still use aluminium alloy, are cast with several lifting lug installation bases 2 (4), boss thereon
Upper thread mill drilling, boss can also supplement connection beam strength；
The replaceable lifting lug 2, material are high-strength steel, and the boss 2 of connection beam body 1 is fixed on by hexagon socket head cap screw
It (4), can be with dismounting and change on.
The present invention has the advantage that attachment beam be it is knockdown, the bolt 3 of lifting lug 2 be fastened on connection beam body 1 on,
Lifting lug is detachable, can replace at any time after fracture；It connects beam body 1 and still uses aluminum alloy materials, light-weight, 2 material of lifting lug is
High-strength steel, intensity is higher, and the service life is longer.
Detailed description of the invention:
Attached drawing 1 is the equipment compartment attachment beam schematic diagram of traditional monoblock cast
In figure: 1 (1) connection beam body；1 (2) lifting lug
Attached drawing 2 is knockdown high-speed trains cabin attachment beam schematic diagram
In figure: 1. connection beam bodies；2. lifting lug；3. hexagon socket head cap screw, 2 (4) boss
Attached drawing 3 is connection 1 schematic diagram of beam body
Attached drawing 4 is 2 schematic diagram of lifting lug
Specific embodiment:
The further explanation contents of the present invention and specific embodiment in conjunction with shown in attached drawing.
The knockdown high-speed trains cabin attachment beam is shown in attached drawing 2, includes 1. connection beam bodies, 2. lifting lugs, 3.
Hexagon socket head cap screw.Lifting lug 2 is fastenedly connected by hexagon socket head cap screw 3 with beam body 1 is connect, and equipment compartment attachment beam is combined into.When hanging
When ear 2 is broken or needs replacing, bolt 3 only need to be unloaded, changes new lifting lug, it is good to be fastened with bolt 3, and no replacement is required entirely connects
Connect beam.
Combined high-speed train apparatus cabin attachment beam of the invention, lifting lug is detachable, once lifting lug fracture only needs individually more
Change lifting lug, it is not necessary to replace entire attachment beam, be remarkably improved attachment beam service life, reduce vehicle maintenance cost.
Claims (3)
1. a kind of attachment beam in combined high-speed train apparatus cabin includes 1. connection beam bodies；2. lifting lug；3. hexagon socket head cap screw,
It is characterized in that attachment beam be it is knockdown, the bolt 3 of lifting lug 2 is fastened in connection beam body 1, can dismounting and change at any time.
2. the attachment beam in a kind of combined high-speed train apparatus cabin according to claim 1, it is characterised in that connection beam body 1
Still aluminum alloy materials are used, lifting lug 2 is detachable, and material is high-strength steel.
3. the attachment beam in a kind of combined high-speed train apparatus cabin according to claim 1, it is characterised in that connection beam body 1
It is cast with boss 2 (4), is connect thereon by threaded hole with lifting lug.
