Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the structural representation of the protective equipment of the damping spring that Fig. 1 provides for the utility model embodiment.
In a kind of specific embodiment, the protective equipment of the damping spring 2 of the locomotive that the present embodiment provides, this protective equipment is the heat-shrink tube 1 be enclosed within damping spring 2, and namely heat-shrink tube 1 is arranged on the outside of damping spring 2.Heat-shrink tube 1 shrink under preset temperature shaping after can wrap the outside of damping spring 2.Heat-shrink tube 2 shrinks shaping under preset temperature, and refer to heat-shrink tube 1 after once heating, heat-shrink tube 1, by means of the memory capability of self, is shrunk to original size shape.Shrink shaping after should wrap the outside of damping spring 2, namely represent be heat-shrink tube 1 shrink shaping after shape should be able to cover all outer side surfaces of damping spring 2, so just can play the effect of real protection damping spring 2.
The operating temperature of damping spring 2 is generally between subzero 50 DEG C to 125 DEG C above freezing, within this temperature range, its working state should not affected by heat-shrink tube 1, namely heat-shrink tube 1 can not interfere the work of described damping spring 2 under the temperature environment between subzero 50 DEG C to 125 DEG C above freezing, and damping spring can normally work between 125 DEG C of temperature ranges above freezing at subzero 50 DEG C.This just requires that heat-shrink tube 1 should possess lower temperature resistance, only possesses lower temperature resistance, can be so just the ability that heat-shrink tube 1 also can have protection damping spring 2 at low ambient temperatures, and does not affect the flexible of damping spring 2.Meanwhile, heat-shrink tube 1 also should possess ductility, because stretching along with damping spring 2, heat-shrink tube 1 also needs to do corresponding distortion.And heat-shrink tube 1 also will possess stronger elastic deformability, because when damping spring 2 is in extended state, heat-shrink tube 1 also preferably can stretch along with damping spring 2, and not damaged.The character that heat-shrink tube 1 possesses, should ensure following 2 points in a word: one is the outside that heat-shrink tube 1 can wrap damping spring 2 always, two is the work that heat-shrink tube 1 can not interfere described damping spring 2 under the temperature environment between subzero 50 DEG C to 125 DEG C above freezing.In actual use, heat-shrink tube 1 is first enclosed within damping spring 2, then heat from one end, before heating, the caliber of heat-shrink tube 11 is generally slightly larger than the external diameter of damping spring 2, if heat-shrink tube 12 does not have the stop of damping spring 2 after heating, caliber after contraction should be slightly less than the external diameter of damping spring 2, makes to heat rear heat-shrink tube 12 and tightly can wrap damping spring 2 under self contractile force and elastic force effect.
Consider that locomotive in use, due to contingency, make damping spring 2 surrounding there is naked light, or temperature is too high, if the material of heat-shrink tube 1 itself is inflammable plastics, fire scope may be expanded or cause fire, so heat-shrink tube 1 preferably fire retardant thermal shrinkage tube, namely there is flame retarding.
Concrete, the heat-shrink tube 1 like this with flame retarding generally directly can select a kind of polyester heat-shrink tube, i.e. PET heat-shrink tube.Also can manufacture according to following explained hereafter: select to account for the polyolefin hybrid resin of heavy about 60%, account for the Halogenless composite fire retardant of heavy about 30% and account for the masterbatch of other auxiliary agent of heavy about 10%, wherein other auxiliary agent generally refers to the blending agent of antioxidant, sensitizing powder and brightening agent.Mixed by masterbatch, through banbury melt blending, obtain particle by single screw extrusion machine, then particle is injection molded into cast by injection machine, caliber is now the caliber after heat-shrink tube 1 pyrocondensation.Then cross-linking radiation is that polyolefinic structure of molecule changes, and this change makes polyolefin have memory effect under certain condition.Then carry out adding thermal enlargement, finally carry out cooling and shaping, heat-shrink tube 11 before the heat-shrink tube 1 after sizing is and shrinks.Owing to having memory effect, so heat-shrink tube 1 heating can be shrunk to the shape size before expansion.
In actual use, because damping spring 2 stretches, heat-shrink tube 1 inside may be caused to have larger space, or gap between two ends heat-shrink tube 1 with damping spring 2 is larger, sleet may be made like this to flow to, make heat-shrink tube 1 not reach better protection effect, so one deck hot melt adhesive can be coated with on heat-shrink tube 1 inwall, heat-shrink tube 1 can be pasted onto on damping spring 2, even if a certain joint heat-shrink tube fails, can also ensure that can not there be sleet in other places near damping spring 2.Hot melt adhesive generally selects ethylene-vinyl acetate copolymer (abbreviation EVA hot-melt adhesive), this EVA hot-melt adhesive be a kind of do not need solvent, not water content, 100% the polymer of solid solubility, be solid at normal temperatures, heating and melting to a certain extent after can fluidify and there is the liquid adhesive of certain viscosity.
