Abstract
The invention relates to a key component of a rail insulation joint, which lies at the rail joint of two ends of a rail line block partition for dividing rail circuit segment and separating adjacent rail circuit belonging to the railroad rail circuit technique field. The invention provides an insulation pad which is provided with high strength and high friction between a rail cap and a clamp (or named as rail splice), wherein the pad uses stainless steel as base, two faces of the pad are baked with enamel which is sanded and roughens the surface to brush a layer of silicon rubber, the outline is the same as the inside surface of the rail joint, the aperture on the pad and aperture distance are the same as the aperture and aperture distance of the clamp. The goal of the key component of the high-strength rail insulation joint is simple in preparation, inexpensive in cost and convenient in assembly, which also satisfies high-load dynamic loading fatigue action.
Description
Technical field
The present invention relates to a kind of critical component of rail insulated joint, it is positioned at the rail joint place at railway track block section two ends, is used to divide the section of track circuit, and the track circuit of separating adjacent belongs to the railway track circuit technical field.
Background technology
Rail insulated joint is positioned at the rail joint at block section two ends, is the important set Chengdu branch of track circuit.The function of rail insulation, be to divide the section of track circuit, the track circuit of separating adjacent, thereby require it to have the good insulation performance performance except that possessing, also should have enough mechanical strengths, make it at rail creeping and bear unlikely very fast destruction under the impact of wheel, to guarantee the security of operation of train.
At present, having on the rail track of track circuit, be used to connect the rail insulated joint structure, mainly contain two types: a kind of is common insulating joint structure, it has simple in structure, easy accessibility, advantage that price is low, but have the shortcoming that structural strength is low, joint resistance is little, joint disease is many, maintenance load is big, this kind insulating joint is a weak link outstanding on the circuit, and influences the speed-raising of rail track; Another kind of for glueing joint the insulating joint structure, it has bulk strength height, good insulation preformance, advantage that maintenance load is few, but shortcomings such as existence carrying inconvenience, construction bother, fault is difficult to processing and on the high side, and this kind insulating joint structure can not be used at some positions of switch area, therefore is unfavorable for the development of trans-section seamless railway.
It is simple to the purpose of this invention is to provide a kind of making, with low cost, easy for installation, can satisfy the high duty rails insulating joint critical component of high load capacity dynamic load fatigue effect again.
Summary of the invention
The present invention makes the high strength between a steel rail ends and clamping plate (or claiming splice bar), the insulating pad of high frictional force exactly, this backing plate be substrate by the thick corrosion resistant plate of 0.3～0.5mm, two-sided roasting enameling, the enamel face is earlier through blasting treatment, behind the rough surface, brush one deck silicon rubber, profile is identical with the rail joint inner surface, aperture on this backing plate is identical with the reservation aperture and the pitch-row of pitch-row and rail and clamping plate, this backing plate length, an end is mutually neat with the neat mutually other end in clamping plate top and steel rail ends.Wherein, greater than the rail case hardness, enough big friction factor is arranged between coarse surface and rail and clamping plate through the enamel case hardness of blasting treatment, the thin silicon rubber layer can prevent that then rainwater from entering the gap of backing plate and rail and clamping plate contact surface.
Description of drawings
Fig. 1 is the rail joint vitreous enamel insulating spacer outline drawing.Fig. 2 is the sectional drawing of the local A of rail joint vitreous enamel insulating spacer among Fig. 1, and wherein 1 is the substrate corrosion resistant plate, and 2 are enamel layer after the sandblast, and 3 is silastic-layer.Fig. 3 is the installation sectional drawing of rail joint vitreous enamel insulating spacer, and wherein 4 is rail, and 5 is clamping plate, and 6 is rail joint vitreous enamel insulating spacer, and 7 is fastening bolt, and 8 is glass fiber reinforced plastic bolt insulation sleeve.Fig. 4 is the installation side view of rail joint vitreous enamel insulating spacer, and wherein 9 are plastic insulation pad between the insulation rail joint.
The specific embodiment
For common rail joint, insulation if desired, plastic insulation pad (9), glass fiber reinforced plastic bolt insulation sleeve (8) between this rail joint vitreous enamel insulating spacer (6), steel rail ends are encased inside between clamping plate and the rail according to Fig. 4, Fig. 5, screw high-strength bolt by standard moment and get final product.Enamel on the pad two sides plays insulating effect like this, and enamel layer has the very high friction factor opposing rail and the relative displacement of clamping plate after the sandblast, and silastic-layer prevents that then rainwater from entering between rail, pad, the clamping plate, reaches purpose of design.
Claims (2)
1, a kind of rail joint vitreous enamel insulating spacer that is used to divide the railway track circuit section, it is characterized in that: paste in the both sides, two rails end that join and put this rail joint vitreous enamel insulating spacer, two clamping plates is placed in the vitreous enamel insulating spacer respectively, track-end insulation spare is placed in the two rails end, screws with the high-strength bolt injection joint preformed hole that puts the glass fibre reinforced plastic insulating sleeve pipe then promptly to constitute rail insulated joint.
2, rail enamel insulating joint pad according to claim 1, it is characterized in that: by the thick corrosion resistant plate of 0.3～0.5mm is substrate, profile is identical with the rail joint inner surface, aperture on this backing plate is identical with the reservation aperture and the pitch-row of pitch-row and rail and clamping plate, this backing plate length, and an end is mutually neat with the neat mutually other end in clamping plate top and steel rail ends, two-sided roasting enameling, the enamel face is earlier through blasting treatment, make its rough surface after, brush one deck silicon rubber.
