Description

A kind of rigid suspended formula monorail transit system

Technical field

This patent is related to a kind of rigid suspended formula monorail transit system, is applied to rail traffic.Specifically, exactly pass through It is proposed that a kind of track beam deflection, vehicle shake smaller rigid suspended formula monorail transit system, it is existing flexible or half to solve Soft half just suspension type monorail railway and highway system track girder deformation is big, vehicle shaking is big, and the running speed thereby resulted in is slow, freight volume Low, the problems such as there are traffic safety hidden danger, belong to suspension type monorail field of traffic.

Background technology

Under track girder, track girder has both load-bearing effect and is oriented to be made vehicle hanging in suspension type monorail railway and highway system With.Angular dimension is shaken according to car body when the malformation size of suspension type monorail railway and highway system and operation, existing can will be hanged Hanging monorail transit system is divided into flexible suspension formula monorail transit system and half two kinds of soft half rigid system.

Flexible suspension formula monorail transit system is generally made of flexible cable 1-r and the car body 4-r of suspention, track when operation Girder construction system deforms and car body shakes very greatly.Flexible cable 1-r load-carrying members and guiding as track system simultaneously Structure.The rigidity very little of flexible cable 1-r, vertical deformation f when stress_rIt is very big, up to more than ten centimetres or even bigger, such as Fig. 1 It is shown.When being acted on by lateral load, for example wind load, the transversely deforming of one side cable very cause cable itself to have greatly One larger lateral shift angle, θ；On the other hand due to being articulated connection between flexible cable 1-r and car body 4-r, therefore car body Relative thereto is generated a larger rotational angle α by 4-r, and the two collective effect has led to car body when operation and shakes very Greatly, angle is shaken up to 15 ° or so, as shown in Figure 2.This suspension type monorail track structure deformation and car body in operation shake It is uncontrollable, lead to that running velocity is very low, freight volume also very little, is only applicable to the works such as park or recreation ground and goes sightseeing to use.

Half soft half rigid suspension type monorail railway and highway system is generally by half soft half rigid track girder 1-m, bridge pier system 3-m and car body There is the Vehicular system composition of larger rotation in relative orbit beam.Wherein, Vehicular system includes bogie 2-m and car body 4-m.It is this Track beam structure deformation and car body shaking are reduced railway and highway system compared with flexible suspension formula monorail transit system at runtime.This The track girder rigidity of the soft half rigid suspension type monorail railway and highway system of kind half is much larger than the rigidity of cable, but due to its generally use bottom The steel construction of the forms such as the Thin Walled Steel Box Beam of opening or steel truss, therefore its lateral stiffness is also unable to reach conventional rebar concrete The lateral stiffness of box beam causes its rigidity between cable and conventional rebar concrete box girder, referred to as half soft half rigid track Beam.This track girder can reduce malformation, control track girder vertical deflection f in bearing load_mThe 1/800 of itself span Between~1/100, it can be met the requirements in engineering, this kind of track beam deflection schematic diagram is as shown in Figure 3.Work as suspension type monorail When vehicle is run, car body is generally made of three parts relative to the shaking angle of track girder, i.e.,：Track girder is relative to pier cap beam Rotational angle θ, shakings of the rotational angle α and car body that bogie is generated relative to track girder change in location relative to bogie Angle beta, as shown in Figure 4.This half soft half rigid suspension type monorail railway and highway system and above-mentioned flexible suspension formula monorail transit system It compares, although the angle, θ that track girder shakes is negligible, since general bogie torsional rigidity is smaller in this system Using hinged (can lead to larger β) between (can lead to larger α) or car body and bogie, therefore (alpha+beta) can still reach one Larger value generally can reach 4 °~15 ° or so, and vehicle shakes larger when leading to the system running.Half soft half rigid suspension type list The malformation of rail railway and highway system and car body shaking are greatly reduced compared with flexible suspension formula monorail transit system, this makes its driving Speed and freight volume are substantially improved, and have both the effect of carrying and sightseeing, thus this suspension type monorail railway and highway system have become it is medium and small The optimal selection of the medium and small freight volume traffic lines such as city, airport line and various short distance traffic lines.

It is completed in world wide at present and several suspension type monorail traffic lines used as public transport mainly uses Match aircraft (Safege) type suspension type monorail traffic that two kinds of patterns, i.e. German blue root (Langen) type and Japan largely use System.Although both single track system track girder forms and the form of Vehicular system are different, all use in nature Be that half soft half just the form of the Vehicular system combination of larger rotation, both forms have occurred in track girder and car body relative orbit beam Belong to half soft half rigid suspension type monorail railway and highway system.Wherein, German (Langen) system uses the track of steel truss girder form Beam, rigidity are more than cable less than reinforced beam, belong to half soft half rigid track girder.In its Vehicular system, although turning The angles rotation β are not present using rigid connect between frame and car body, but using hinged between the travelling wheel and track girder on bogie Form is attached, therefore the angles rotational angle α that bogie is generated relative to track girder change in location will be very big, therefore leads to (alpha+beta) It is very big, facts proved that the system (alpha+beta) can reach 15 ° or so.And match aircraft (Safege) type single track system of Japan uses bottom For the Thin Walled Steel Box Beam of portion's opening as track girder, rigidity belongs to half soft half between cable and armored concrete steel box-girder Rigid track girder；Using the bogie for not setting steady wheel, antitorque and anti-shake dynamic arm of force very little, when leading to operation in its Vehicular system There are the larger angles α.Meanwhile articulated form is used between bogie and car body, cause the angles β also very big, therefore (alpha+beta) is very big, one As at 4 ° or more.In summary, existing suspension type monorail railway and highway system has belonged to this half soft half just in world wide at present Suspension type monorail railway and highway system.

Connection between existing suspension type monorail railway and highway system bogie and car body substantially using flexible connection, That is articulated form.As patent No. CN106218648A discloses a kind of suspension type monorail car body beam connecting structure and suspension type list Rail vehicle, the invention is by being arranged overhead structure, the barb cooperation of crossbeam and connecting plate, so that crossbeam and suspension type car body Between realize non-rigid connection, avoid the dependence to welding manner, solve the internal stress that suspension type body movement is brought. But this non-rigid connection makes car body easy to produce larger shaking at runtime, influences drive a vehicle stationarity and running speed.

China Patent No. CN106004912A discloses a kind of steering reducing suspension type monorail traffic train transverse shakiness Frame adds side arm on the longeron of bogie, steady wheel is arranged on side arm, mutual by bogie longeron, side arm, suspension arrangement Effect forms antitorque frame system and travelling wheel, directive wheel, steady wheel form antitorque space-load system to increase train With the lateral stiffness of bogie system, achievees the purpose that balance train, reduces transverse shakiness.Although the patent can reduce by turning The shaking angle [alpha] generated to frame, but car body can not be reduced and shake the angle beta generated.

In view of the above-mentioned problems, and combining existing flexible suspension formula monorail transit system and half soft half just suspension type monorail friendship The deformation of entire body architecture is big, car body shakes the actual conditions such as big, freight volume is small, in conjunction with a large number of experiments and experience of applicant, from rail Road girder construction deformation and car body shake principle and set out, and carry out theory analysis, finally propose this patent.

Specific implementation mode

A kind of rigid suspended formula monorail transit system is described further below in conjunction with attached drawing, should be referred to before this Go out, being intended only as demonstration by attached drawing described embodiment illustrates, and is not considered as limiting the invention.

A kind of one rigid suspended formula monorail transit system of prestressed concrete bottom opening of embodiment

In conjunction with Fig. 5, Fig. 6 and Fig. 7 to based on a kind of rigid suspended formula of prestressed concrete bottom opening described in this patent Monorail transit system carries out demonstration explanation.The rigid suspended formula monorail transit system of a kind of prestressed concrete bottom opening Including prestressed concrete bottom opening box track girder 1-a, the bogie 2-a for adding steady wheel, L-shaped bridge pier system 3-a and Car body 4-a.

For in terms of the structure and function, prestressed concrete bottom opening box track girder 1-a is main carrying knot Structure and guide frame pass through suspended bearer S_aMounted on the bent cap G of L-shaped bridge pier system 3-a_aLower section.Add the bogie of steady wheel 2-a is placed in the inside of prestressed concrete bottom opening box track girder 1-a, and travelling wheel is placed in prestressed concrete bottom plate D_a On inner surface, directive wheel is placed in prestressed concrete web W_aIn the lower surface of inside, steady wheel is placed in prestressed concrete Native web W_aOn the upper face of inside；The bogie 2-a and car body 4-a for adding steady wheel pass through bolt L_aIn a manner of fastening and connect It is whole to form a rigidity for rigid connection.The bogie 2-a for adding steady wheel primarily serves the effect that limitation vehicle shakes.

For in terms of the stress and deformation, the prestressed concrete bottom opening suspension type monorail railway and highway system is in operation The effect being mainly subject to has conducting oneself with dignity, secondary dead load, prestressed load, train static live load, train impact load, centrifuging for track girder Power, wind load and train rocking force etc..

For track girder：

Make in vertical loads such as track girder dead weight, secondary dead load, prestressed load, train static live load, train impact loads Under, track girder is primarily subjected to the effect of vertical moment of flexure and vertical shear, generates vertical deflection deformation.At this point, track back bottom Plate is mainly used for unbending, and roof and floor is in compression or tension state；Track beam web is mainly used for shearing resistance, web be in by Scissor state.

The lateral loads such as centrifugal force, wind load and train rocking force effect under, track girder be primarily subjected to transverse bending moment, Transverse shearing force and torque effect, generate transversely deforming and torsional deflection.At this point, track girder roof and floor is mainly used for unbending, Roof and floor is in by curved state, but in view of track girder roof and floor transverse width is larger, causes its lateral bending stiffness also larger, And the transverse bending moment that track girder is subject to is typically small, therefore the transversely deforming under transverse bending moment effect can be ignored；Track beam web Be mainly used for it is antitorque, web be in by turn round state.

From the above analysis, in the case where runing load action, track girder roof and floor is mainly acted on by tension and compression, track beam web Mainly by vertical shear and twisting action.

A kind of rigid suspended formula monorail transit system of prestressed concrete bottom opening is opened using prestressed concrete bottom Mouth box track girder 1-a, upper plate use roof support with reinforced concrete U_a, and by increasing top plate thickness and the longitudinal steel of configuration Muscle improves its Anti-pull-press ability, to realize the purpose of rigid panel；Its web uses prestressed concrete web W_a, pass through increasing Big web thickness configures stirrup and applies prestressing force to improve its shearing resistance and anti-twisting property, to realize the purpose of rigid web； Its bottom plate uses prestressed concrete bottom plate D_a, carried by increasing base plate thickness, configuration longitudinal reinforcement and applying prestressing force Its high Anti-pull-press ability, to realize the purpose of stiff baseplate.It is operated by above several respects, realizes that prestressed concrete bottom is opened Mouth box track girder 1-a is the purpose of rigid track beam.

Experiment prove, rigid track beam can generally meet the vertical deflection in the case where run load action be not more than itself across The 1/800 of degree, prestressed concrete bottom opening box track girder 1-a vertical deflections deform f_aAs shown in Figure 5.Due to suspension type The characteristics of monorail transit " beam body is track ", the track girder of small deformation will ensure the flat of the linear controllability of track and driving It is pliable, provide precondition for the raising of running speed.On the other hand, the track girder of small deformation, ensure that itself and bogie Normally deformation matching, avoids the problem of causing bogie tire to be stuck greatly because of track girder section deformation between tire.

For bogie and car body：

The lateral loads such as centrifugal force, wind load, nosing force act on the car body, and are transmitted on bogie, make bogie Lateral shaking is generated with car body.The angle of shaking includes the rotational angle α that bogie is generated relative to track girder change in location Shaking angle beta with car body relative to bogie.The rigid suspended formula monorail transit system vehicle of the prestressed concrete bottom opening It is as shown in Figure 6 that body shakes angle.

It is as shown in Figure 7 that bogie and track girder simplify stress model.It can be seen from the figure that being transmitted to bogie by car body Lateral load can be reduced to act on a horizontal force F of a bogie position of centre of gravity and torque M.Due to leading herein The anti-torsion ability of bogie is analyzed, therefore only analysis torque M acts on the stressing conditions of lower bogie.When bogie is by torque When M is acted on, the steady wheel that contact with track beam web and a pair of counter-force F will be generated with the travelling wheel of track girder contacts baseplate₁Come Moment of resistance M.According to the equilibrium principle of torque, there are equilibrium relation M=F₁× a, a are for directive wheel stress point on diagonal line and surely The distance between fixed wheel stress point.Because of F₁Size be generally dependent on the interaction of track girder and bogie tire, therefore want The anti-twisting property for improving bogie, can only increase the distance between directive wheel stress point and steady wheel stress point a on diagonal line, this It is equal to and increases the distance between homonymy steady wheel and travelling wheel, you can with the distance between homonymy steady wheel and travelling wheel size The anti-twisting property of a bogie is weighed, when the distance between side steady wheel and travelling wheel be bigger, the anti-twisting property of bogie It is bigger.

A kind of rigid suspended formula monorail transit system of prestressed concrete bottom opening is using adding turning for steady wheel To frame 2-a, bogie frame structure K_aHalf rigid bogie frame soft compared to half is additionally arranged steady wheel above directive wheel.It can Know to stablize to take turns to the distance between travelling wheel and be more than to be oriented to and take turns to the distance between travelling wheel, i.e., weighing the antitorque energy of bogie The distance of power increases, and the anti-twisting property for the rigid bogie 2-a for adding steady wheel is increased with this, to realize rigid bogie frame The purpose of frame structure；The bogie and car body use bolt L_aIt fastens the mode of connecing to be rigidly connected, nothing between bogie and car body Relative movement, to realize the purpose rigidly fixed.It is operated by above several respects, realizes the rigid bogie 2- for adding steady wheel A is the purpose of rigid bogie.

Experiment proves that for rigid bogie when being acted on by lateral load, rigid bogie frame can guarantee bogie phase For the windup-degree α very littles of track girder, generally no greater than 3 °；And it is then eliminated using rigid connection between bogie and car body Shaking angle beta of the car body relative to bogie.Therefore car body shaking angle (alpha+beta) will be controlled within 4 ° when runing, this is Passenger provides preferably comfort；The fatigue effect for also reducing bogie simultaneously, reduces the security risk of system.

For bridge pier system：

The lateral loads such as wind load and the load come from track girder and car body transmission will act in bridge pier system, make bridge Pier pier top generates horizontal displacement, and bent cap generates vertical deflection, and hanging anchoring system generates direction across bridge rotation or moves and lead to rail Road beam generates a rotational angle theta relative to bent cap, as shown in Figure 6.At this point, bridge pier bending moment and pressure effect, bent cap is mainly by curved Square and shearing action, hanging anchoring system are mainly acted on by vertical tension, cross force and lateral torsion.

The bridge pier Q of L-shaped bridge pier system 3-a_aIts stress rigidity is improved by increasing section size, to realize rigid bridge The purpose of pier；Bent cap G_aBy increasing bent cap depth of section and configuring longitudinal reinforcement and stirrup, and carried using prestressing technique The bending resistance of high bent cap and shear resistance, to realize the purpose of Rigid Pier；Hanging anchoring system is by using constraint lateral rotation With mobile suspended bearer S_aThe anti-shake dynamic deformation ability of itself is improved, to realize the purpose of rigid anchoring system.By with Upper several respects operation realizes that L-shaped bridge pier system 3-a is the purpose of Rigid Pier system.

Experiment proves that the malformation of Rigid Pier and rigid bent cap in the case where runing load action is smaller, meets use and wants It asks；Rigid anchoring system can constrain rotation of the track girder relative to bent cap, eliminate rotational angle theta of the track girder relative to bent cap.It solves Half soft half just bridge pier pier displacement and bent cap deformation is excessive leads to drive a vehicle that ride comfort is poor, goes out in suspension type monorail railway and highway system The problems such as now jumping vehicle.Meanwhile by eliminating rotational angle theta of the track girder relative to bent cap, car body shaking is reduced, improves passenger's Comfort improves the freight volume and reliability of system.

It, can be very using a kind of rigid suspended formula monorail transit system of prestressed concrete bottom opening according to the above analysis Track girder vertical deformation and the shaking of car body are controlled well, to make rigid suspended formula monorail transit system keep better circuit Linear, guarantee driving safety and driving ride comfort provide condition to improve running speed.Meanwhile car body shaking is reduced, change It has been apt to the comfort of passenger, has improved the freight volume and reliability of system.
