When entering rolling stock section based on monorail train and overhauling storehouse, or special circumstances Train needs when surprisingly going out line end
Brake in time, this utility model provides a kind of straddle-type monorail and fixes car bumper.
Next, car bumper will be fixed to straddle-type monorail from basic engineering, extension design, alternative design etc. being retouched in detail
State：
A kind of straddle-type monorail fixes car bumper, and as Figure 1-4, which includes：Fixed structure and buffer structure.Fixed structure
It is mainly used in providing the fixation of car bumper, it is to avoid shift in the presence of huge impulsive contact force.Buffer structure is mainly used in receiving
Huge impulsive contact force, enters row buffering, and discharges counteracting force.Wherein fixed structure is arranged in prefabricated PC beams 4, at buffer structure
In the outside of PC beams 4, and in the top of fixed structure, fixed structure is fixedly connected with buffer structure.Wherein, buffer structure master
To be constituted by clashing into guiding piece 8 and buffering restoring piece, guiding piece 8 is clashed into for impact force is guided to buffering restoring piece, buffering
Restoring piece is for entering row buffering by impact force.The shock portion contact train coupler of guiding piece 8 is clashed into, directly receives impulsive contact force, its
Rigidity and impact resistance ability are stronger, and shock portion can be a part for clashing into guiding piece 8, it is also possible to pacify as separate part
Loaded on shock guiding piece 8.The one end for clashing into guiding piece 8 is connected with buffering restoring piece, and buffering restoring piece is to buffering percussive force
And discharge restoring force.
In order to improve warning function, the striking face 1 in shock portion arranges warning strip；The warning strip can be strip, planar, can
Think and be applied to striking face 1, it is also possible to be pasted onto above, striking face 1 can be arranged on other usual ways.The warning possesses
Reflecting effect, such as：Red reflective, yellow is reflective or other colors it is reflective.
In addition, warning sign 5 can be set everywhere in fixed car bumper, such as：The top of buffer structure arranges circuit end
End warning sign 5.Warning sign 5 is set in certain altitude, observing effect can be strengthened.
When train clashes into, clash into radical and first contact train, receive and clash into kinetic energy, and the shock kinetic energy is delivered to into buffering
Restoring piece.The shock portion is box like stereochemical structure, and one end of box like stereochemical structure arranges striking face 1, opposite other end and buffering
Restoring piece connects.
Effectively guide to buffering restoring piece in order to kinetic energy will be clashed into, casing stereochemical structure inwardly arranges blind hole from striking face 1.
By the energy expenditure of blind hole, loss when shock portion is impacted is reduced.
Because fixed structure needs to provide powerful fixed supporting role, therefore, PC beams 4 are made full use of in this technique,
Fixed structure is embedded in PC beams 4.The fixed structure can be designed as the structure being made up of multiple fixed steel columns 3, fixed steel
The upper end of post 3 is fixedly connected with buffering restoring piece.Can be connected using bolt 7 between the upper end of fixed steel column 3 and buffering restoring piece
Connect, weld, draw-in groove connection etc., welding is relatively stable mode, and the transmission effect of power is more uniform, but, for convenience
Change, dismantle, it is proposed that using bolt 7 or the connected mode of draw-in groove.
In certain embodiments, fixed steel column 3 is preferably and is evenly arranged, and to equalize stress, strengthens fixed effect.And
And, the number of fixed steel column 3, height, diameter can be according to practical situation (such as car load, vehicle joint number, car speed
Deng) and set, in addition, in further embodiments, fixed steel column 3 can be replaced with other structures, such as：Fixed block；
Fixed claw etc..All structures for playing fixed, supporting role are all in protection domain.
In order to further improve fixed effect, the lower end of fixed steel column 3 arranges and laterally bends；Add by horizontal restraint
It is strong fixed.
Based on above-mentioned basic engineering or extension design, buffering restoring piece is mainly by steel construction main body 2 and hydro-pneumatic buffer
Composition.The hydraulic cylinder of hydro-pneumatic buffer arranges the inside of steel construction main body 2, and hydraulic stem 6 and the shock portion of hydro-pneumatic buffer are fixed
Connection.Hydraulic stem 6 is received and clashes into kinetic energy, is moved in the presence of kinetic energy is clashed into, and promotes hydro-pneumatic buffer to open buffer mode.
The inside oil pocket of hydro-pneumatic buffer is divided into the first oil pocket and the second oil pocket, the first oil pocket by the tail end of hydraulic stem 6
And second arrange valve opening between oil pocket.Internally oil pocket is portable for hydraulic stem 6, and the oil in the first oil pocket is oily into second by valve opening
Chamber, the space of the second oil pocket diminish, and oil mass increases.
And, filled with nitrogen in the second oil pocket, as the space of the second oil pocket reduces, the gas compartment is also with the feelings for reducing
Under condition, the air pressure of nitrogen increases, and promotes the movement of 6 opposite direction of hydraulic stem, progressively opens reforestation practices.
Supporting body of the steel construction main body 2 for hydro-pneumatic buffer, which needs to keep being relatively fixed with fixed structure, so steel knot
The lower edge of structure main body 2 is fixedly connected with fixed structure.
The shock kinetic energy of train is passed to hydraulic jack by shock guide (clashing into guiding piece 8) (to buffer
Restoring piece), hydraulic oil is arranged to another chamber (the second cavity) from a chamber (i.e. the first cavity) of oil cylinder by valve opening, while producing big
The heat of amount, consumes the inertia kinetic energy of train out of control, and during hydro-pneumatic buffer is compressed, oil cylinder total capacity reduces, nitrogen
The pressure increase of gas, gathers substantial amounts of pressure energy, afterwards being automatically releasable by pressure energy, realizes automatically reseting for car bumper.Should
The brake force of car bumper equipment can change with the energy variation of train is clashed into, can effective protection vehicle.
Car bumper is fixed in order to prepare above-mentioned straddle-type monorail, as shown in figure 5, following steps can be adopted：
The fixed structure that straddle-type monorail fixes car bumper is positioned over the production location of PC beams by step 110；
Car bumper built-in fitting is carried out according to size pre-buried before PC beams are poured, and ensure car bumper embedded board position dimension.
Step 120, in the prefabricated PC beams of production location, fixed structure is imbedded, and exposes the upper end of fixed structure；
Step 130, the buffer structure that straddle-type monorail fixes car bumper is positioned on PC beams, and position is in fixed structure
Top；
Step 140, fixed structure is fixedly connected with buffer structure.
After PC beams are machined, the buffer structure of single track car bumper is lifted on into PC beams upper end, with car bumper built-in fitting position pair
Together, car bumper clamping screw is tightened one by one and completes car bumper installation.
Straddle-type monorail storehouse internally-fixed liquid gas buffering car bumper is arranged on PC beams end.
It should be noted that straddle-type monorail fix car bumper in manufacturing process, institute welding in need position (compare
Such as：The prefabricated light plate junction of steel construction main body is welding position) all process through flaw detection during welding.
The various embodiments that this utility model is provided can be mutually combined as needed in any way, combined by this
The technical scheme for arriving, also in the range of this utility model.Obviously, in the situation without departing from spirit and scope of the present utility model
Under, those skilled in the art can carry out various changes and modification to this utility model.If changed to of the present utility model these
Dynamic and modification is that within the scope of claim of the present utility model and its equivalent, then this utility model also will be comprising this
It is a little to change and modification.
