Description
Technical field
The utility model belongs to railway switch field, especially relates to a kind of disc spring external locking device.
Background technology
Existing external locking device for railway tie, as dovetail type external locking device and hook-type external locking device, dovetail type external locking device uses in railway speed increase in early days in a large number, owing to adjusting difficulty, serious wear, stressedly unreasonablely to be eliminated gradually, the hook-type external locking device of current use generally uses on railway switch, but also exist volume comparatively large, take up room large, unlock and change the phenomenons such as jam, operation is affected, simultaneously because scantling of structure excessive being unfavorable for of the stressed wear-out part of key carries out PROCESS FOR TREATMENT, and PROCESS FOR TREATMENT uneconomical.
In the locking iron construction of general type, latch hook fitting surface is constant inclined surface, and closely connected tab is completely fixed, and cannot adapt to track switch vibration.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of disc spring external locking device, effectively can reduce locking conversion power, can solve again the problem of the locking iron latch hook fitting surface abnormal wear that external locking device occurs because track switch vibration is excessive.
The technical solution adopted in the utility model is:
A kind of disc spring external locking device, comprise roller, bearing pin, bolt, disc spring buffer structure, locking iron, locking frame, spring buffer structure comprises disc spring axle sleeve, disc spring, disc spring pad, locking iron centre portion is provided with a groove, bearing pin is horizontally through groove, it is inner that level is installed on locking iron, bearing pin is positioned at the flexible roller of arranged outside of the part of groove, groove both sides are respectively provided with a bolt, it is inner that bolt level is installed on locking iron, vertical with bearing pin, bolt arranged outside has disc spring axle sleeve, bolt bottom is provided with disc spring, disc spring pad is provided with on the downside of disc spring, closely connected tab is provided with on the downside of spring shim, disc spring, disc spring pad is between locking iron and closely connected tab, closely connected tab is positioned at locking frame upper surface place.
Further, lining is provided with between described bearing pin and elastic roller.
Further, the material of described lining is high-abrasive material.
The advantage that the utility model has and good effect are:
The utility model latch hook coordinates for elastic roller, and between closely connected tab and locking iron, increase disc spring buffer structure, when track switch is vibrated, elastic roller and disc spring buffer structure can cushion the vibratory impulse of track switch, reduces the abrasion between locking iron and latch hook; During locking, cliding friction is become friction of rolling by elastic roller.Can ensure switch locking, can reduce again track switch conversion locking force, actv. solves the problem of the latch hook locking iron inordinate wear that track switch vibration causes.
Accompanying drawing explanation
Fig. 1 is disc spring external locking device front view.
Fig. 2 is disc spring external locking device birds-eye view.
Fig. 3 is disc spring external locking device left view.
In figure:
1. locking iron, 2. locking frame, 3. bolt, 4. disc spring axle sleeve, 5. disc spring, 6. disc spring pad, 7. closely connected tab, 8. bearing pin, 9. elastic roller.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in FIG. 1 to 3, a kind of disc spring external locking device, comprise roller 9, bearing pin 8, bolt 3, disc spring buffer structure, locking iron 1, locking frame 2, spring buffer structure comprises disc spring axle sleeve 4, disc spring 5, disc spring pad 6, locking iron 1 centre portion is provided with a groove, bearing pin 8 is horizontally through groove, it is inner that level is installed on locking iron 1, bearing pin 8 is positioned at the flexible roller 9 of arranged outside of the part of groove, groove both sides are respectively provided with a bolt 3, it is inner that bolt 3 level is installed on locking iron 1, vertical with bearing pin 8, bolt 3 arranged outside has disc spring axle sleeve 4, bolt 3 bottom is provided with disc spring 5, disc spring pad 6 is provided with on the downside of disc spring 5, closely connected tab 7 is provided with on the downside of spring shim 6, disc spring 5, disc spring pad 6 is between locking iron 1 and closely connected tab 7, closely connected tab 7 is positioned at locking frame 2 upper surface place.
Be provided with lining between bearing pin 8 and elastic roller 9, the material of lining is high-abrasive material.
Latch hook coordinates for elastic roller, increases disc spring buffer structure between closely connected tab and locking iron, and when track switch is vibrated, elastic roller 9 and disc spring buffer structure can cushion the vibratory impulse of track switch, reduce the abrasion between locking iron 1 and latch hook; During locking, cliding friction is become friction of rolling by elastic roller 9.Can ensure switch locking, can reduce again track switch conversion locking force, actv. solves the problem of latch hook locking iron 1 inordinate wear that track switch vibration causes.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
