Abstract
The utility model discloses a kind of rail fastener insulating pad, comprise the rectangle like backing plate that adopts insulation materials to make, the two ends external surface of described rectangle like backing plate respectively symmetrical offer for the storage tank being fixed of the front end edge of the spring of rail fastener, described rectangle like backing plate middle part offer with rail fastener in the arc storage tank that is fixed of the front end arc flanging of spring.The utility model is after installation is fixing, the front end edge of spring is fixed in storage tank, the front end arc flanging of spring is fixed in arc storage tank, so compress rail by the utility model, and compress contact for face contact, the frictional force of increase and rail, prevents that rail from sliding, and stops potential safety hazard.And the utility model utilizes insulation materials to make, prevent that the electric charge between spring and rail from shifting.
Description
Technical field
The utility model relates to rail fastener technical field, particularly a kind of insulating pad for coordinating with railway fastening elastic rod SKL 15.
Background technology
Existing rail fastener assembly generally comprises rail, rail pad, sleeper bolt, spring, gauge apron, base plate, elastic bottom plate pad and insulation sleeve, insulation sleeve is arranged on rail in advance, rail pad, base plate and elastic bottom plate pad are arranged under rail successively, by sleeper bolt, the gauge apron on both sides and spring are screwed again, to fix rail, the effect of fixation assembly is played in sleeper bolt screw-in insulation sleeve inside.
Shown in Figure 1, the tail end arc flanging 41 of the spring 40 of the rail fastener assembly of this structure can slide to for 11 times with arc mounting groove 12 and be fixed along the arc chimb of gauge apron 10, now, the front end arc flanging 42 of spring 40 can be chimeric fixing with arc positioning groove 13, the front end edge 42a of spring 40 can leave chute 14 and moves forward and block rail 50, plays the effect of fixing rail 50.But the front end arc flanging 42 that this fixed form makes spring 40 and front end edge 42a and rail 50 lower surface are almost and contact, and frictional force is inadequate, rail 50 easily occurs and slide, and brings potential safety hazard.And due to material cause, between spring 40 and rail 50, be conductive contact, easily cause electric charge to shift, also can bring potential safety hazard.
Utility model content
The purpose of this utility model is for shortcomings and deficiencies of the prior art, and a kind of rail fastener insulating pad is provided, and utilizes this rail fastener insulating pad can prevent that rail from sliding, and further fixes rail.
The technical problem that the utility model solves can realize by the following technical solutions:
Rail fastener insulating pad, it is characterized in that, comprise the rectangle like backing plate that adopts insulation materials to make, the two ends external surface of described rectangle like backing plate respectively symmetrical offer for the storage tank being fixed of the front end edge of the spring of rail fastener, described rectangle like backing plate middle part offer with rail fastener in the arc storage tank that is fixed of the front end arc flanging of spring.
Owing to having adopted technical scheme as above, the utility model is after installation is fixing, the front end edge of spring is fixed in storage tank, the front end arc flanging of spring is fixed in arc storage tank, so compress rail by the utility model, and compress contact for face contact, increase the frictional force with rail, prevent that rail from sliding, and stops potential safety hazard.And the utility model utilizes insulation materials to make, prevent that the electric charge between spring and rail from shifting.

Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the rail fastener insulating pad shown in Fig. 2 to Fig. 5, comprise the rectangle like backing plate 100 that adopts insulation materials to make, the insulation materials in the present embodiment is the polyamide that contains 30% fiber glass reinforcement, and has anti-daylight and characteristic ultraviolet.The two ends external surface of rectangle like backing plate 100 respectively symmetry offers storage tank 110, and rectangle like backing plate 100 middle parts offer arc storage tank 120.
In conjunction with Fig. 6, when pre-installation, referring to state I in Fig. 6, the front end arc flanging 420 of spring 400 is fixed on the installation base 300 of gauge apron 700, on the chute 320 that the front end edge 421 of spring 400 pre-fixes, the tail end arc flanging 410 of spring 400 pre-fixes at the first arc chimb 210 tops, on position corresponding to spring 400 front ends on rail 500, be placed with rectangle like backing plate 100, the arc storage tank 120 of rectangle like backing plate 100 is aimed at the front end arc flanging 420 of spring 400, when after the good tie bolt 600 of pre-installation, after confirming that installation site is errorless, referring to state I I in figure, tie bolt 600 is further screwed, the tail end arc flanging 410 of spring 400 can slide to for 210 times with arc mounting groove 220 and be fixed along the first arc chimb, the front end edge 421 of spring 400 is pressed in the storage tank 110 of rectangle like backing plate 100, the front end arc flanging 420 of spring 400 can be pressed in arc storage tank 120, rectangle like backing plate 100 is pressed on rail 500, plays the effect of fixing rail 500.And rectangle like backing plate 100 is that face contacts with the compression of rail 500, the frictional force of increase and rail 500, prevents that rail 500 from sliding, and stops potential safety hazard.And the utility model utilizes insulation materials to make, can also prevent that the electric charge between spring 400 and rail 500 from shifting.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
