Abstract
The utility model relates to hot-rolling F-shaped profiled bar used for middle-speed and low-speed magnetic suspension train track. The cross section of the profiled bar is of a F shape, and the profiled bar comprises a inclined leg (1), a web plate (2), a straight leg (3) and a level extension section (4). The center line of the inclined leg and the lower surface of the web plate form a included angle, the upper and lower surfaces of the level extension section and the upper and lower surface of the web plate are parallel or in a same plane, and the straight leg is arranged at a joint of the web plate and the level extension section. Each corner is circular arc in shape. Unlike a F-shaped profiled bar welded by steel plate, each joint of the hot-rolling F-shaped profiled bar is circular arc transition, and the two sides of the inclined leg and the straight leg and the lower web plate both form a included angle of 92-110 DEG. The purpose of the design is to guarantee the product to be produced through hot-rolling while not need welding and mechanical processing, thereby simplifying the manufacturing process, reducing the cost, enhancing the production efficiency, increasing rigidity and strength of the inclined extension section and the vertical extension section, and enhancing use safety.
Description
Technical field
The utility model relates to a kind of deformed steel, particularly a kind of middle low speed magnetic suspension train track hot rolling F type deformed steel.
Background technology
1969, begin to carry out magnetic suspension train research in the world, through years of researches and practice, middle low speed magnetic suspension system has accumulated many successful experiences.In the research and the application facet of middle low speed magnetic suspension, the most representative is low speed magnetic suspension traffic system in the Japan.Middle low speed magnetic suspension traffic technique appears at Germany the earliest, and Japan successively developed 7 middle low speed magnetic suspension vehicle models through nearly 30 years research, developed into the H100 series of Nagoya, and system moves successfully.Hills, east, Nagoya line, positive line length 8.9km, wherein 1.4km is a underground cable, all the other are overhead route, are provided with nine stations, and the minimum row workshop is divided into 6min during the peak, flat peak period running interval is 10min, interval highest running speed 100km/h, one way 15min running time, a day freight volume is 1.5 ten thousand person-times.Formally be open to traffic on March 5th, 2005.Also have Daewoo's test wire, the U.S. AMT of Korea S with the similar system of HSST.
China begins often to lead the research work of low-speed maglev train in the type from the eighties initial stage, " eight or five " state key program for tackling key problems in science and technology is listed in magnetic-levitation train key technology in 1992 research in, obtain interim result of study, and successfully realized the manned operation of full-scale single bogie in the laboratory first in nineteen ninety-five.
Beijing Holding Magnetic Suspension Techn Development Co., Ltd. in 1999 and the National University of Defense technology organizes in concert, the enterprise of railway, aviation, the tool technical advantage of automobile and other industries has built Chinese article one magnetic-levitation train test wire in Changsha University of Science and Technology for National Defence campus in the United Nations, and finish the manufacturing of full-scale test vehicle production; September calendar year 2001, Full Vehicle System began to carry out operation test.
CN1621618 discloses a kind of travel that is used for magnetic suspension train, this road comprises that is bearing in a supporting construction of especially being made by steel concrete or prestressed concrete on the ground, this supporting construction has the edge that stretch out the side tabularly on the position that interrelates with vehicle, the suspension framework of on this edge, arranging the magnetic-levitation traveling mechanism by vehicle take the shape of the letter U around functional unit-as sliding panel, stator and side guide rail, make the minimized in size in the slit of the transmission sound between the end portion vehicle suspension framework and supporting construction, and to make this slit be the labyrinth form.At this moment, the height in slit and width approximately corresponding the tolerance dimension of the magnetic-levitation traveling mechanism on sliding panel and the position side guide rail.
CN2869102 discloses a kind of middle low-speed maglev train track, and rail directly is fixed on the both sides of beam by bolt or pre-buried mode; The soffit of rail fixedly is inverted U in the bottom of inverted U suspension rail or rail in the bolt mode, constitutes the inverted U suspension rail.
Problems such as the low speed magnetic suspension train track has box steel, i iron and U shaped steel several types with shaped steel in existing, has low precision in the practical application, and complexity is installed, and the tracks positioned difficulty is big.The middle low speed magnetic suspension test wire track of Japan adopts weather-resistant steel plate welding and machinery to be processed into, though precision is higher, waste of material is serious, and cost of manufacture is high, and production efficiency is low, is difficult to realize mass production, only can satisfy the requirement of present small lot test.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of raising product precision, simplify installation steps, reduce the tracks positioned difficulty, reduce production costs again simultaneously, save material, enhance productivity, satisfy a kind of middle low speed magnetic suspension train track hot rolling F type deformed steel of the requirement of industrialization, mass.
Low speed magnetic suspension train track hot rolling F type deformed steel in a kind of, it is characterized in that, the cross section of this deformed steel is a F shape, form by four parts: battered leg, web, straight leg, the level section of stretching out, wherein between battered leg center line and the web soffit angle theta is arranged, the level section of stretching out upper and lower surface is parallel to each other or at grade with the web upper and lower surface respectively, and straight leg is positioned at web and the level section of stretching out junction.
Described battered leg is identical with respect to the vertical height of web soffit with straight leg.
Each corner of described deformed steel is circular arc.
Angle theta between described battered leg center line and the web soffit is the obtuse angle, and angle is between 92～120 degree, and preferred 95～105 spend.
The angle that 92～110 degree are all arranged between described battered leg and straight leg both sides and the bottom web.
The effect of battered leg is to cooperate with the brake of middle low speed magnetic suspension train car body to finish braking procedure; The following transverse plane of battered leg and straight leg and the interaction of the electromagnet of car body produce power upwards suspends car body.The level section of stretching out plays interconnect function, and the low speed magnetic suspension train track connects easily with hot rolling F shaped steel and is fixed on the sleeper in can making, and has higher strength and stiffness.The design of web is for the ease of tablet being installed in the above, the driving force of level being provided for car body during operation.
Different with the F type deformed steel of steel plate welding processing is, each corner of deformed steel is a circular arc, and battered leg and straight leg both sides all have certain gradient, this design is in order to guarantee that this product can directly need not weld and machining by the method production of hot rolling, to have simplified manufacturing process, having reduced cost, improved production efficiency, simultaneously, improve the rigidity and the intensity of the tilt section of stretching out and the vertical section of stretching out, strengthened the safety of using.
