Abstract
The present invention is adjustable wedged spring leaf type fastener and its fastening method, and belongs to the field of railway track switch manufacture technology. The fastener includes a tongue on the bed plate, a spring leaf inside bed plate cavity, and a wedged locating block in the back end of the bed plate cavity, with the back end of the spring leaf being located on the wedge surface of the wedged locating block. The present invention has the advantages of improved spring leaf stress condition and strength without fault of breaking; high safety and reliability, simple and flexible assembling and disassembling suitable for field operation.
Description
Technical field:
The present invention relates to a kind of wedge shape and adjust spring leaf type buckle and withhold method, belong to the railroad turnout railway switch and make the field.
Background technology:
Before the rolling stock speed-raising, the slide plate of domestic turnout switch part is to be welded by two block plates up and down, the sliding bed of the inboard main employing of stock rail platform presses the tongue rigidity to withhold (Fig. 8), cause tongue part elasticity relatively poor, form track structure and vertically reach the lateral stiffness irregularity, train by the time between wheel track, cause strong shock and vibration, thereby aggravated the dynamic action between wheel and tongue and tongue and the slide plate, worsen the condition of work of track switch, cause the shortening in application life of track switch part component, also injure traffic safety when serious.
After the rolling stock speed-raising, domestic slide plate begins to adopt the mode elasticity of shell fragment and pin to withhold stock rail inboard (Fig. 9), compbined test test result according to Qinhuangdao-Shenyang track switch, train by the time railway switch part stock rail horizontal maximum displacement value be 1.07mm, can satisfy the specially instructions for use of track switch of visitor fully, but owing to be subjected to the restriction of the stock rail and the AT rail discrepancy in elevation, cause the strength deficiency of shell fragment and pin, on-the-spot indivedual shell fragments and the pin found has hurt, the traffic safety of serious threat train.Along with railway speed constantly improves, guarantee that slide plate safety, reliable, lasting elasticity withholds the stock rail inboard and just become urgent problem.
Summary of the invention:
Purpose of design: provide a kind of and can satisfy the required buckle press in stock rail inboard (flange of rail), improve tongue district elasticity, whole switch area rigidity is reached unanimity, and can strengthen taking the passenger vehicle comfort level, prolong the sphenoid adjustment striking flake type fastener in track switch component application life and withholding method of passenger.
Design scheme: since the visitor specially track switch ride comfort, the elasticity of circuit is had extra high requirement, therefore not only the stock rail inboard must have enough buckle presses, and improve the elasticity in tongue district, whole switch area rigidity is reached unanimity, could strengthen the comfort level that the passenger takes passenger vehicle, prolong the application life of track switch component.Therefore on structure design, at used shell fragment of acclerating road switch slide plate and pin strength deficiency, there is problems such as fractureing, install difficulty, can't satisfies the on-the-spot instructions for use of railway switch, consider to improve slide plate withholding the stock rail inboard from shell fragment, platen structure and location and installation mode.(flange of rail) original shell fragment, platen have been carried out bigger change from structure, the mode of withholding, can satisfy simultaneously the use of special track switch of visitor and common acclerating road switch, mainly improve: 1. at the shell fragment strength deficiency from several aspects once, occur fractureing individually, so increase shell fragment thickness, shell fragment becomes in 11～15mm scope optional by original maximum ga(u)ge 10mm, structurally also change simultaneously, the boss with position limiting structure has been designed in both sides, rear end at shell fragment, reach the intensity that improves shell fragment, reduce the purpose of its stress; There is the hurt problem that fractures during 2. at the fastening shell fragment of pin, so the cancellation pin changes existing shell fragment pin button shape locating piece and supports elastic piece structure.Both sides, shell fragment rear end be provided with boss and with two walls of platen rear end U font perforated wall on the groove coupling, it is mobile to guarantee that shell fragment can not produce, purpose is to have improved the shell fragment force-bearing situation, and mounting and dismounting are convenient; 3. after cancelling the fastening shell fragment of pin, have enough buckle presses in order to ensure shell fragment, improve the fit form of platen and shell fragment, be provided with support rim, the platen inner chamber is provided with positive stop lug boss simultaneously; 4. wedge locating block is provided with spacing locking, tripper, this spacing device for locking and unlocking, and both location that can wedge locating block is firm can unlock again as required.
Technical scheme 1: sphenoid adjustment striking flake type fastener, tongue are positioned on the platen, and shell fragment is positioned at the platen inner chamber, and wedge locating block is positioned at the rear end of platen inner chamber and the rear end of shell fragment is positioned on the lozenges of wedge locating block.
Technical scheme 2: the method for withholding of sphenoid adjustment striking flake type fastener, the flange of rail of stock rail one side is fixed on the base plate, tongue is positioned on the platen, shell fragment is positioned at the platen inner chamber, the front end of shell fragment is positioned on the flange of rail of stock rail opposite side, the rear end of shell fragment is positioned on the lozenges of wedge locating block and by lozenges raises, the middle part of shell fragment is pushed down by the support rim of platen inner chamber, under the effect of external force, forcing shell fragment to form two ends upwarps, middle recessed, the wedge locating block of middle boss and rear end forces the shell fragment that is positioned on the stock rail opposite side flange of rail to produce buckle press, and wedge locating block is positioned at the rear end of platen inner chamber and is locking or opening by spacing locking tripper and platen.
The present invention compares with background technology, the one, sphenoid adjustment striking flake type fastener has fundamentally changed the shell fragment stress condition, has improved the intensity of shell fragment, the shell fragment pin that the shell fragment pin mode of withholding of having avoided acclerating road switch to adopt the occurs problem that fractures, its shell fragment weak spot maximum stress value reduced by 36% than the maximum stress value of existing shell fragment; The 2nd, this structure elasticity is lastingly withheld the stock rail inboard, and is safe and reliable; The 3rd, sphenoid adjustment striking flake type fastener is in the installation of shell fragment and disassemble all than simple and flexible, adapts to railway field work and maintenance; The 4th, this structure through a series of experimental tests can satisfy simultaneously the visitor specially turnout baseplate elasticity withhold requirement, started the frontier that the safe and reliable elasticity of turnout baseplate is withheld the stock rail inboard.
