Description
Technical field
The utility model relates to field of track traffic, and relates more specifically to a kind of fastening devices and track circuit reinforcement system.
Background technology
Beam track strengthening system (being track circuit reinforcement system) is widely used in domestic bridge pushing process in length and breadth, its structure is made up of i iron crossbeam arranged in parallel and longitudinal member, wherein beam vertical extends in track circuit, and longitudinal member is parallel to track circuit and extends.Longitudinal member mainly can comprise longeron and rail girder, and wherein, longeron is tied up into by many i iron and a branch ofly to be formed, and rail girder is tied up into by many one steel rails and a branch ofly to be formed.Train rail is held up by crossbeam, and longitudinal member is between each track and be placed in above crossbeam.The point of intersection of longitudinal member and every root crossbeam is bound by U-bolt, and thus, crossbeam and longitudinal member constitute beam track strengthening system in length and breadth.Framed underpass bridge construction with top with in the process of digging, if having train by job site and through frame bridge and excavation slight slope between space because there is the support of beam track strengthening system in length and breadth, train is able to safety.
When beam track strengthening system bears train load in length and breadth, crossbeam is as the main member bearing train load, and the effect of longitudinal member comprises: 1) make the amount of deflection of this crossbeam and stress comparatively large when time above train wheel is positioned at any single crossbeam, and longitudinal and transverse beam plays the effect of sharing train load, restriction beam deformation after binding together; 2) when vehicle is by reinforcement system, along rail direction wheel track between horizontal applied force can be passed on crossbeam and cause crossbeam to reverse, and provide the resist torque for this moment of torsion with the longitudinal member that crossbeam binds together, crossbeam can normally be worked; 3) when vehicle is by reinforcement system, the vibration of the reinforcement system caused due to various factors (resonance etc. as the insufficient rigidity of reinforcement system, track irregularity, vehicle and reinforcement system) easily makes crossbeam produce displacement, and the longeron of longitudinal member and crossbeam bind together and make crossbeam suffer restraints to guarantee that it normally works.As can be seen here, the Main Function of longitudinal member is: jointly form firm bent structure to ensure that train safe passes through with crossbeam.
But form of structure and the connected mode of the existing track strengthening of beam in length and breadth system determine its existing defects on force-mechanism, make the operating efficiency of beam track strengthening system in length and breadth lower, less effective.In the current track strengthening of beam in length and breadth system, longeron is positioned at above crossbeam, and is being connected by U-bolt with the Nodes of crossbeam.Under U-bolt pulling force effect after tightening, the effect that longeron restriction beam deformation and constraint crossbeam reverse relies on the normal force between vertical cross beam contacting surface to realize, and the effect that longeron suppresses crossbeam to produce relative displacement relies on the frictional force on contact surface to realize.But, for such reinforcement system, if when train is through out-of-date generation larger vibration, especially when vehicle dynamic load causes the resonance of reinforcement system, amplitude sharply increases, add crossbeam far-end because whipping effect is to the amplification of displacement, often make U-bolt deform or loosen gradually, cause the relative sliding in length and breadth between beam, this slip exacerbates again the distortion of U-bolt conversely, weakens the fastening force in length and breadth between beam.
In the job site of beam track strengthening in length and breadth, by again fastening for the beam connection in length and breadth (as U-bolt) loosened be a heavy and warm work, consume a large amount of manpower; And, even if sometimes there is sufficient staff to be also difficult to: on the circuit that driving is intensive, the time interval that train passes through is very short, in order to support personnel's safety, there will be the firm upper track of workman to start to construct the situation descending road to keep away car soon, rear car has to pass through from the reinforcement system that connector is fully not fastening, adds the danger of driving and engineering.In addition, on heavy haul transport circuit, heavy haul train may reach more than 1 kilometer, through track strengthening system job site, macro-axis is heavy and under the effect of ultra-long time, the loosening of reinforcement system connector becomes very large potential safety hazard.
Therefore, design a kind of device that can ensure that track circuit reinforcement system normally works firmly, for a long time to have become engineering and need badly.
