Description
Technical field
The present invention relates generally to track structure, particularly relates to the track structure and the manufacture method thereof of low speed magnetic floating traffic.
Background technology
In normal lead Induction Motor-Driven magnetic floating system, the both sides of rail beam are unsettled " U " shape steel ferromagnetism guide rail.Be fixed on the hold concurrently electromagnet of guiding usefulness of suspension on the magnetic-levitation train and just in time place the guide rail below, and iron core is " U " shape, the guide rail of " U " is relative with falling.During train operation, electromagnet produces the suction that attracts guide rail from the below, and train utilizes this suction and suspends.When car body electromagnet and guide rail generation transversion malposition, produce oblique gravitation between them, the horizontal component of this gravitation will play the effect of corrected transposition, thereby realize guide function.
Said system adopts the type of drive of short stator line inductance electromotor.That is, lay the rotor of reaction plate (being generally aluminium matter) falling the upper surface of " U " shape guide rail, the stator of these linear electric motors is installed on the car body above it as linear electric motors.After stator is fed three-phase alternating current, produce a shifting magnetic field, owing to the effect in this magnetic field produces tractive force.
By the principle of aforementioned low speed magnetic floating system as can be seen, " U " shape guide rail (" F " because of its cross section looks like to lie down often is called the F steel plate) that falls wherein is the critical component of this system track structure.The F steel plate supports the train slide travelling wheel in addition and the effect of rubbing surface is provided for the braking of train hydraulic braking pincers except playing the effect that suspends guiding and drive.Therefore, in engineering is used, for providing orbit, train just becomes the key technical problem of magnetic suspension traffic system construction thereby guide rail and its supporting construction combined.
With regard to above-mentioned magnetic floating system, often lead the low speed magnetic floating line as Japanese HSST, and domestic low speed magnetic floating test wire, its track structure that adopts generally all is that the F steel plate as track is bearing on the rail beam by sleeper.Japan Patent JP3257201 and Chinese patent CN2584643Y have just disclosed such sleeper type magnetic floating traffic track structure, sleeper is wherein generally made by i iron or concrete, and sleeper is connected on the backing plate or precast concrete cushion block that is embedded in the rail beam end face by bolt.Traditional railway sleeper form commonly used has been adopted in this connection, though can solve the installation question of low speed magnetic floating track, its cost height, maintenance workloads such as preservative treatment are big.In addition, owing on the rail beam face many sleepers are set, all brought difficulty for the regular maintenance and passenger's the evacuation in emergency circumstances of circuit.The air-flow that is produced when vehicle is advanced at a high speed also can improve noise level.
Japan Patent JP3333301 has disclosed a kind of " guide rail that the aspiration-type levitation train is used and the advance system that is used for this guide rail ", it has proposed a kind ofly directly guide rail to be connected in the guide rail form of rail beam side, thereby has solved the problem that above-mentioned sleeper form low speed magnetic floating track structure exists.Yet for the rail beam on the curve circuit, when adopting this technical scheme, the horizontal wall inscription of circuit and horizontal wall inscription reverse the Liang Tishang that must be located at rail beam.So just need to adopt different template manufacturings to have the rail beam of different sweeps or curvilinear motion rate, thereby the requirement of rail beam manufacturing and complexity are improved greatly, thereby be very uneconomic.Therefore, the applicability of this technical scheme also has been subjected to very big restriction.
Japan Patent JP4272301 has disclosed a kind of " orbit trimming fixed structure ", and it has proposed a kind of form that guide rail is directly installed on rail beam upper surface both sides.Also there is the manufacturing that the makes rail beam complicated problems that becomes in this technical scheme.
Summary of the invention
For overcoming the defective of above-mentioned prior art, the objective of the invention is to, a kind of simple in structure, track structure and manufacture method thereof of being convenient to the magnetic floating traffic making and install is provided.
Another object of the present invention is, a kind of magnetic floating traffic track structure and manufacture method thereof that is specially adapted to the curve highway section is provided.
For achieving the above object, the invention provides a kind of track structure of magnetic floating traffic, comprise rail beam, be positioned at the guide rail of upper surface both sides of rail beam and the syndeton that these two parts are coupled together, syndeton comprises securing member, wherein, syndeton also comprises the cushion block that is arranged between rail beam and the guide rail as structural connection.
The present invention also provides a kind of manufacture method of track structure of magnetic floating traffic, comprises the steps: to prepare a rail beam; Prepare a guide rail, this guide rail will be set to the both sides of the upper surface of described rail beam; Also comprise the step of described rail beam being fixedlyed connected with described guide rail by as the cushion block of structural connection.
For obtaining above-mentioned track structure, the invention provides three kinds of enforceable schemes.
Scheme one is that prefabrication and mach steel member are as cushion block.The steel member body is the square steel pipe of vertically placing, and these square steel pipe both sides connect by bolt or the welding angle steel, connect guide rail and concrete track beam respectively, be reserved with the reinforcing bar of projection on the rail beam, insert in the square steel pipe, concreting in square steel pipe, thus finish and being connected of rail beam.
Scheme two is the precast concrete cushion block.Be connected by bolt between cushion block top pre-embedded steel slab, guide rail and pre-embedded steel slab; Except that bolt is connected, can also add fastener being set connecting between guide rail and pre-embedded steel slab; WELDING STUDS pre-buried on the cushion block and tension bolt are inserted rail beam face preformed hole, and concreting is realized being connected of guide rail and rail beam again.
The core component of scheme three is an i-steel component, this steel member top flange is outwards chosen, connect guide rail with bolt, stretch out to the rail beam center line this steel member bottom flange, the WELDING STUDS of bottom flange by bolt and welding inserted in the rail beam in the preformed hole, realizes and being connected of rail beam by concreting again.
In above-mentioned three kinds of schemes, the definite of guide rail position can adopt following two kinds of methods:
Method one is: under the situation of the rough precision of control, at first cushion block and rail beam are built and be integral, the increase pad is accurately adjusted position, mounting guide rail between guide rail and pre-embedded steel slab then.
Method two is: at first cushion block and guide rail are fixed together, utilize frock and pass through the accurate locus of measuring, adjusting guide rail, cushion block and rail beam are coupled together by grouting again.
In above-mentioned three kinds of schemes, the route curve horizontal wall inscription is arranged on the described cushion block, by adjusting pad tile height and end face inclination angle, cooperates with the guide rail of factory bend fixing, and it is linear to form route curve.Cushion block is processed in factory to reach the certain precision requirement, because the cushion block yardstick is less, this is easy to realize very much.
The present invention has following advantage:
1. the rail beam pattern is unified, saves template, has reduced manufacturing complexity and difficulty;
2. route curve is arranged on the cushion block on the slope in length and breadth, greatly facilitates that to adjust circuit linear, and method is simple, and cost is low.
3. utilize frock to form the section of track and carry out the guide rail location, be convenient to the linear adjustment of guide rail, improve efficiency of construction.
