Description
Technical field
The invention belongs to railway freight loading and reinforcing technologies, are related to goods loading and reinforcing equipment, are a kind of special specifically
For covering the catch of catch wheel type cargo.
Background technology
When transporting cargo with rolling stock, cargo will be reinforced after loading.It is with a kind of triangular prism shape for cylindrical goods
Equipment covers gear, which is known as triangle gear, and cross-sectional profiles are isosceles triangles；For Wheel type goods（Such as automobile, engineering
Vehicle）, radius of wheel is larger, is to cover gear with triangle gear, radius of wheel is smaller, is to cover gear, so-called catch and one with catch
Kind triangular prism shape equipment, differs only in, and covering on gear working face has an arc groove consistent with wheel contour.Reinforcing device
Material is in use, be anchored on Goods bearer.
Above-mentioned reinforcing equipment is manufactured with timber earliest, is disposable consumables, timber consumption is very big, not only transports
It is defeated of high cost, also increasingly conflict with forestry code, it is difficult to be after.Afterwards to mould Dai Mu, it is changed to be made of plastic.
Existing plastics gear, main material is plastics and mineral powder, is aided with auxiliary agent, avoids and conflicts with forestry code,
As the direction of development.But there is also some problems, mainly：
1st, plastics are combustible, and there are fire safety evaluating hidden danger；
2nd, plastic products are easy to aging, strength reduction, and expired plastics gear cannot use, the bad assurance of railway department inventory stock amount,
Loss from spoilage is larger.
3rd, the structure design of product is not good enough, and force analysis not science, dimension scale, cloth muscle position be not quite reasonable, causes to produce
Product weight is larger, and materials are more, and mold is complicated, and process is more, and the manufacturing cycle is long.
Invention content
In view of the above problems, the present invention improves the material and structure of product, the following technical solutions are proposed：
A kind of catch is made after being uniformly mixed with the raw material of following parts by weight through hot extrusion cold pressing：
HDPE resins 100
LDPE or POE resin 15 ~ 20
Red soil 30 ~ 70
Lubricant 1
Coupling agent 1
Antioxidant 0.5
Carbon black 0.15
Fire retardant 33
The lubricant selects HSt stearic acid；The coupling agent selects KR-212 coupling agents；The antioxidant includes main antioxygen
Agent and auxiliary anti-oxidant, primary antioxidant select 1010 antioxidant, dosage 0.2, and auxiliary anti-oxidant selects DLTP antioxidant, and dosage is
0.3；The fire retardant includes deca-BDE and plumbous plumbate, and deca-BDE dosage is 25, plumbous plumbate dosage
It is 8.
The catch be triangular prism shape, tool there are one bottom surface, one as cover gear working face before, a back side,
Two end faces in left and right, cross-sectional profiles is fall " V " shapes, profile line is isosceles triangle, " V " shape internal abdominal walls have it is vertical perpendicular
The reinforcing rib of intertexture；The gear working face of covering has arc groove corresponding with wheel contour for face where a waist on the working face；
The back side is face where another waist, is the vertical perpendicular reticular structure to interweave in the middle part of the back side, mesh is counterbore；Have on the bottom surface
Support rim, rearwardly holdfast perforation platform is extended in direction for the bottom surface；There is deep gouge on the end face, there is end face reinforcement in deep gouge
Muscle.
The end face of the catch is composed of Upper vertical face and lower bevel, left and right two end faces lower bevel by
Both ends are tilted to middle point symmetry, and the longitudinal length of catch bottom surface is made to be less than the longitudinal length on gear top.
Beneficial effects of the present invention：By the improvement above to material prescription and product structure, product is greatly improved
Performance, securely and reliably, be easy to keeping and lay in, it is anti-aging, good weatherability, antistatic, fire-retardant, to mould Dai Mu, reduce gloomy
Woods is cut down, environmentally friendly, has significant society, environmental protection, economic benefit.Following table is the Mechanics Performance Testing of product, completely
Meet the ministry standard of the former Ministry of Railways.
Material property value test value ministry standard
