Description
Technical field
The present invention relates to medium-and low-speed maglev technical field of rail traffic, be specially a kind of medium-and low-speed maglev system F shaped steel double slit jointing.
Background technology
The track structure of medium-and low-speed maglev system is mainly made up of the section of track of piecemeal, fastener system and track.The section of track can at the scene or factory-assembled, it is connected with the track of cast in situs by fastener system, simultaneously, for the deformation that adaptation infrastructure and the section of track cause under variations in temperature, need between the section of track to arrange expansion joint, the size at expansion joint, should meet and be not zero when historical high temperature to guarantee not hold out against between the section of track stress, when historical low temperature less than structural joint gap to guarantee that train smooth runs.
Between the section of track, F shaped steel double slit jointing is provided between the adjacent section of track connecting device of expansion joint position, and the stroke between the section of track is assigned to two expansion joints by this structure, is therefore adapted for mount between the section of track that relative telescopic amount is bigger.At present, existing at home and abroad put in actually used F shaped steel double slit jointing, the interior lower limb of its main F shaped steel and outer lower limb have been provided with two pieces of cushion blocks protruded, under wing plate, are welded with two pieces of cushion blocks, with vertical support secondary F shaped steel simultaneously；The processing of main F shape steel web position has the boss with screw, by limiting the lateral attitude of secondary F shaped steel with the matching relationship of secondary F steel section size with groove, and utilizes the pressing plate and connecting bolt that are arranged on boss, is fixed by secondary F shaped steel vertical.
Though above-mentioned jointing can meet the connection request of the section of track, but in use, still come with some shortcomings: 1. owing to the boss of main F shape steel web position is arranged, make secondary F shape steel web length too short, cause when magnetic-levitation train passes through double slit jointing, suspension detecting device is easily made mistakes, and the collision of induction coil and tablet, the safety of impact driving can occur under extreme case；2. buckle realize owing to major and minor F shaped steel lengthwise position relies only on the longitudinal spacing being arranged on outer lower limb side, cause that, when low temperature limit buckle holds out against, secondary F shaped steel is subjected to bigger moment of torsion, affect the horizontal ride comfort of track；3. magnetic-levitation train is when utilizing emergent support to take turns operation, owing to major and minor F shaped steel is " one " font seam at flap position, is severely affected when emergent support is taken turns by this seam, affects the ride comfort of track and the emergent life-span supporting and taking turns.
Summary of the invention
Therefore, for the deficiency overcoming prior art to exist, the present invention provides a kind of medium-and low-speed maglev system F shaped steel double slit jointing that can keep orbital forcing.
nullFor solving above-mentioned technical problem，Medium-and low-speed maglev system F shaped steel double slit jointing of the present invention includes two sections of main F shaped steel 1 being provided with in first lower limb 1-1 and the first outer lower limb 1-3、One section of secondary F shaped steel 2 being provided with in second the outer lower limb 2-3 of lower limb 2-1 and the second and two block pressur plates 4,The outer lower limb 1-3 of lower limb 1-1 and the first is respectively equipped with in described first the first of protrusion and connects cushion block 1-2 and the second connection cushion block 1-4，Described second end connecting cushion block 1-4 is provided with the main limit buckle 1-5 of vertical projections，In described second, lower limb 2-1 is provided with and is connected cushion block 1-2 the first connecting platform 2-2 matched with first，Described second outer lower limb 2-3 is provided with and is connected cushion block 1-3 the second connecting platform 2-4 matched with second，The end of described second connecting platform 2-4 is provided with the secondary limit buckle 2-5 of vertical projections，In described second, secondary F shaped steel 2 two ends between lower limb 2-1 and the second outer lower limb 2-3 are provided with boss 2-6，The link of described two sections of main F shaped steel 1 is equipped with the shrinkage pool 1-6 matched with boss 2-6，Described secondary F shaped steel 2 two ends are withheld between two sections of main F shaped steel 1 by two block pressur plates 4.
Present invention achieves the vertical and lateral connection of two sections of main F shaped steel and one section of secondary F shaped steel, longitudinally the relative telescopic of two sections of main F rails can be assigned to two expansion joints, and have the advantage that compared with existing structure
1, secondary F shaped steel two link of present invention web position between interior lower limb and outer lower limb arranges the boss sunk relative to end face, when not increasing sleeper pitch, significantly increase the web length of secondary F shaped steel, it is ensured that safety and reliability when train is by double slit jointing.
2, major and minor F shaped steel longitudinal spacing realizes by being arranged on the outer limit buckle of lower limb side of F shaped steel and the connecting plate of wing plate side, and when making low temperature, secondary F shaped steel longitudinal stress is more reasonable, and joint track transverse direction ride comfort keeps.
3, major and minor F shaped steel link " ladder " type at wing plate place connects, impact suffered when effectively alleviating emergent support wheel by double joint, is conducive to the maintenance of orbital forcing and extends the emergent service life supporting and taking turns.
4, by pressing plate, connecting plate with the vertical changing of the relative positions of limit major and minor F shaped steel, by the horizontal changing of the relative positions with limit major and minor F shaped steel of the breach of secondary F shape steel web position boss and flap position, therefore, it hangs down, cross spacing ability is higher.
5, present configuration is simple, easy for installation, for ease of maintenaince.
After reading in conjunction with the accompanying the detailed description of embodiment of the present invention, the other features and advantages of the invention will become clearer from.
