Specific embodiment

With reference to the accompanying drawing, the utility model is described in detail.

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

Suspension type monorail traffic system is a kind of railway traffic system, and there are no operation lines to build up at home at present, Its bridge pier is generally steel structure pier, and reinforced concrete bridge pier is more rare, and height is higher in rail level than other kinds of bridge High 6m or more (Vehicle suspension is under beam body) under unanimous circumstances is spent, therefore bridge pier is integrally relatively high, generally in urban district Bridge pier height is in 14m~17m under normal circumstances, because this kind of standard is required to comparatively strictly landscape, investment and land occupation etc., Therefore general pier section is also smaller, under normal circumstances, domestic existing vehicle in 3 marshallings, 30m across freely supported structure its bridge pier Sectional dimension should be less than 1m × 1m, at this point, the spring level displacement of bridge pier pier top longitudinal direction can not under longitudinal load effect Meet the requirement of the domestic standard formulated at present.

Before " suspension type monorail traffic design standard " (in August, 2018) is not promulgated, bridge pier is usually suspension type monorail It is designed using strength control, principle mainly has two, first is that guaranteeing knot according to " railroad bridge Code for design of steel structures " requirement Intensity, stability and fatigue behaviour of structure etc. do not control the deformation of bridge pier, but must guarantee that each component of structure can normally make With；Second is that guaranteeing driving comfort level requirement using vehicle-bridge interaction analysis.The reason of considering in this way is suspension type monorail knot Structure and conventional railway bridge have essential difference, it is believed that and suspension type monorail bogie is built within bridge rail spar-box body, Be not in the derailment occurring generated because pier displacement is excessive, as long as therefore structure safety, vehicle safely, meanwhile, cannot Because the rigidity of structure is insufficient, comfort of passenger is caused to can not meet requirement.At this point, by the average high 15m of pier, girder span 30m (suspension type Single track simply supported beam girder span is generally up to 30m, and beam just sharply increases when 30m or more, more wastes, also influences landscape and increase Difficulty of construction etc.), the case where 3 vehicles marshalling, calculates, and the sectional dimension of bridge pier is about 0.9m × 0.9m, can meet above want It asks.

But the domestic suspension type monorail design standard formally promulgated has Sichuan Province's provincial standard " suspension type now Monorail transit design standard ", other include existing such as the suspension type monorail traffic design standard that rail traffic association writes The stage is consulted on, whichsoever standard all provides that the spring level displacement of the bridge pier pier top longitudinal direction in the case where longitudinal force acts on is answered Meet:(wherein, L is span).In the case where such pier top is limited along bridge to displacement, the sectional dimension of bridge pier is in pier height When 15m, with under above-mentioned same case, the change in size of steel pier is 2.3m × 0.9m, and sectional dimension than pressing intensity originally Big 2 times or more when control design case, at this point, only the project amount of bridge pier increases 180% or more, and pier Gao Yue great, section Size is bigger.And suspension type monorail is completely elevated bridge, every kilometer of a minimum of 34 bridge pier is practical far more than the value, because The current linear beam of suspension type monorail can accomplish 30m across but camber beam maximum is across generally only 25m, suspension type monorail are different In other traffic standards, great advantage be curve can flexible arrangement, therefore, line alignment is generally with adaptation to the ground requirement Standard, curve accounting is larger, and general 50% or more.

The appearance of design standard brings detrimental effects to the popularization of this newborn traffic standard of suspension type monorail, through surveying It calculates, the bridge being designed using this standard did not promulgated the preceding bridge designed using strength control, project cost than originally standardizing Every kilometer about increases by 13,000,000 RMB (not comprising the increased expense in basis), meanwhile, detrimental effects are brought to landscape.

As shown in Fig. 2, suspension type monorail is according to conventional railway, highway, municipal administration or the letter of other kinds of rail traffic bridge Strutbeam design method is designed, and hold-down support 30 is arranged in one end of simply supported beam, longitudinal living in the other end setting of simply supported beam Dynamic support 31, the activity of longitudinally-moving support 31 have to be larger than the displacement of longitudinal force generation, guarantee longitudinally-moving support 31 Energy Free Transform, the longitudinal forces overwhelming majority such as brake force are transferred to 30 place bridge pier 1 of hold-down support under longitudinal force effect, longitudinal 31 place bridge pier 1 of movable bearing support is only assigned to few longitudinal force because the coefficient of friction of longitudinally-moving support is smaller, and when design is past It is born toward longitudinal force is safely relatively thought of as only 30 place bridge pier 1 of hold-down support.At this point, being acted in longitudinal forces such as brake force Under, do not consider that longitudinally-moving support 31 resists horizontal force action, meanwhile, bridge pier 1 is controlled using Intensity Design, is calculated solid 1 pier top vertical equity of bridge pier displacement where determining support 30 is Δ₁, Δ at this time₁Value is typically much deeper thanSpecification is unsatisfactory for want It asks.

To solve the above-mentioned problems, the invention proposes a kind of schemes, as shown in figure 3, main thought is suspension type monorail Beam body energy Free Transform under temperature load effect, and camber beam can longitudinal Free Transform (both under Vehicle Load Frequency of loading action is higher, has an impact if limitation to 31 durability of longitudinally-moving support), to track under Braking 2 longitudinally-moving of beam is constrained, by longitudinally-moving support 31 " locked ", by suspension type monorail bridge pier 1 when longitudinal force is excessive into Brake force, is transferred to the bridge pier 1 in vehicle forward direction by row series connection, so that the brake force of all bridge piers 1 is in the reasonable scope, At this point, the pier displacement Δ being calculated₂=Δ₁/ n (n is the number for transmitting the bridge piers of longitudinal forces such as brake force), meets pier top DisplacementThis is with respect to excessively strict requirements for suspension type monorail.Therefore, under this mentality of designing, longitudinally-moving Support 31 will also have certain longitudinal direction to move freely displacement and longitudinal braking function simultaneously.For this purpose, the present invention is specially set A kind of novel longitudinally-moving support, i.e., following supports 6 have been counted, and longitudinal direction move freely displacement and longitudinal braking function It is then to be realized by longitudinal adjustment apparatus.
