Abstract
The utility model relates to a safety feature used for preventing the rupture of welding lines of a railway rail. The safety feature is composed of a plywood, a stickiness layer and a reinforcing device. The inside shape of the plywood is a geometry shape which is inosculated with the rail head mandible of the railway rail, the rail waist and the top surface of the rail bottom; the stickiness layer is arranged between two faces to agglutinate the plywood and the railway rail. An outer side face of the plywood is vertical to an axial lead; a groove propped by a transverse bolt is arranged using the axial lead as the center; the lower part of the outer side is arranged as a concave step shape, and the upper part of the outer side is connected by a pitch arc. The reinforcing device is enclosed by a baffle plate, a gauge apron and lateral plates, and the space between two lateral plates is designed in the width which can contain a sleeper as the best. A lug boss part is inosculated with the concave step shape arranged at the lower part of the outer side of the plywood to play a role of supporting the plywood. The lower part of the reinforcing device is designed as a U shape, when installing, the bottom of the rail bottom is blocked in the U shape, so the reinforcing device can be firmly fixed at the bottom part of the rail. The reinforcing device can improve the strength and firmness of the plywood with effect for long period, and has rail pressing and rail supporting function.
Description
Affiliated technical field
The utility model belongs to the railway track joint technical field, relates in particular to a kind of safety device that is used to prevent the steel rail welding line fracture.
Background technology
Along with railway transportation constantly to the heavy duty, high speed development, the track structure seamless process is imperative.Rail joint adopts scene " perforating train wheel bridge " to prevent the aluminothermy welding seam breaking usually at present, and the rail perforating not only slackens the intensity of self, and site operation also will be subjected to driving instrument, operating condition restriction, and the nonstandard meeting of eyelet causes artificial potential safety hazard.The intensity of aluminothermy weld seam only is 70% of rail strength of parent in addition, and above-mentioned joint has become the weak link of track.
Summary of the invention
For guarantee driving safety, solve above technical problem, the purpose of this utility model provides a kind of at the bonding clamping plate in steel rail welding line place, and utilizes the safety device of the further fixing prevention steel rail welding line fracture of stiffening device.Its objective is such realization: it is made up of clamping plate, adhesive layer and stiffening device.The inboard of clamping plate is shaped as the geometry that matches with rail head of rail lower jaw, the web of the rail and flange of rail end face, is glue-line between the two sides, and clamping plate and rail are bonding.Clamping plate lateral surface and axial line are perpendicular, are that the center is provided with to the groove of going into cross bolts with the axial line, and outer lower portion is arranged to recessed step-like, and the outer upper camber line connects.Stiffening device is surrounded by baffle plate, gauge apron and side plate to be formed, and spacing is a benefit with the width that can hold sleeper between biside plate.Projection section that baffle plate and side plate are provided with and clamping plate outer lower portion are arranged to recessed step-like matching, clamping plate are played a supporting role, U-shaped is arranged in the bottom of baffle plate and side plate, and flange of rail bottom snaps in the U-shaped structure in the time of fixedly, can make stiffening device be securely fixed in flange of rail end.Gauge apron is pressed on flange of rail end face and the sleeper, is provided with the apron block that soft materials is made between the end of gauge apron and the sleeper.Cross bolts is supported into the clamping plate groove by the through hole of reserving on the baffle plate, tightens back crosswise fixed clamping plate.Spring and plain washer fastening nut are installed on gauge apron, are made stiffening device and sleeper firm engagement.The baffle plate middle part is provided with the semiarc shape groove from top to bottom, so that the bolt railway spike is installed.Terse for describing, other are not stated parts and are prior art.
Compared with prior art the clamping plate design of section is reasonable for the utility model, and bond area is good; Shear strength＞the 26mpa of high-strength structureal adhesives; Peel strength＞=3.5kn/m; Fatigue test＞=2,000,000 time, hardening time is fast, and adhesive is stable; Stiffening device improves clamping plate intensity and fastness, reaches permanently effective, and has the rail of pressure and the effect of support rail; The utlity model has safe, economical and practical, simple to operate stable, the advantage of not destroying rail strength, for heavy duty, at a high speed shipping or high speed passenger transportation (300 kilometers/time more than) train provide the transportation guarantee of safety and stability.
