Abstract
The utility model relates to a buffer, and more particularly relates to a built-in protective screening type polyurethane buffer. The built-in protective screening type polyurethane buffer comprises a polyurethane elastomer (1), a soft metal screen (2) and an embedded iron piece (3). The built-in protective screening type polyurethane buffer is characterized in that the embedded iron piece (3) is composed of a round disk (4), a reinforcing steel bar (5) and a screw (6); the reinforcing steel bar (5) is welded in the middle of the round disk (4), the other end of the reinforcing steel bar (5) is welded with a hexagonal end of the screw (6); through holes (7) are evenly arranged in the round disk (4), and metal wire holes (8) are evenly arranged in the periphery of the round disk (4). The soft metal screen (2) is fixed on the embedded iron piece (3) by metal wires (10) and cast with the polyurethane elastomer (1) together. The built-in protective screening type polyurethane buffer has the advantages that every performance index of the buffer is not changed, the service life is prolonged, and both the stability and the reliability of long-term use are enhanced.
Description
Technical field
The utility model relates to a kind of buffer, more specifically to a kind of built-in protecting net formula polyurethane bumper absorber.
Background technique
Thereby buffer is a kind ofly to slow down impact, absorb to transform the protection work that collision energy plays the safety protection effect, has been widely used in industries such as lifting, transportation, mining industry, harbour, smelting, boats and ships.Polyurethane bumper absorber is to utilize high scalability that foaming polyurethanes elastomer self had and the micropore bubble structure that gathers wherein to absorb impact kinetic energy, and its foam structure is equivalent to miniature air bag spring one by one.That polyurethane bumper absorber has is simple in structure, easy for installation, in light weight, non-maintaining, shock-resistant, absorb that energy is big, corrosion-resistant, noise is little, insulation explosion-proof, restorative advantage such as good; But because polyurethane is a kind of macromolecule polymeric material; Have anti-aging power poor, not UV resistant, deficiency such as high-and low-temperature resistance not again; Therefore the problem of crackle or local fracture also can appear in the outer surface of polyurethane bumper absorber in use for some time, and this has brought hidden danger to safety in production.And the polyurethane bumper absorber safety and reliability that we need use; Therefore at the inner software wire netting that increases by with metal wire knitted one-tenth of buffer; The potential safety hazard that crackle or local fracture bring occurs thereby solved, prolonged buffer working life because of reasons such as polyurethane material is aging cause the outer surface of polyurethane bumper absorber.
The model utility content
The technical problem that the utility model will solve is: a kind of built-in protecting net formula polyurethane bumper absorber is provided, under the situation that guarantees former polyurethane bumper absorber each item performance index, prolongs the working life of buffer, make the polyurethane bumper absorber safety and reliability.Therefore we weave columned software wire netting according to the polyurethane bumper absorber boundary dimension of different model; The software wire netting is fixed on the preburied iron part; Cast in polyurethane elastomer; Fundamentally having solved itself is the potential safety hazard that buffer produced of safety protection element, has realized secondary protection function.
The utility model comprises polyurethane elastomer, software wire netting, preburied iron part; Its characteristics are: preburied iron part is made up of disk, reinforcing bar and screw; Be welded with reinforcing bar in the middle of the disk; The other end and the screw of reinforcing bar are welded to connect, and on disk, are uniformly distributed with through hole, on the periphery of disk, are uniformly distributed with wire hole.The software wire netting is fixed on the preburied iron part, casts in polyurethane elastomer.
The utility model has the advantages that: do not change each item performance index of buffer, prolonged working life, strengthened the stability and the reliability of long-term use.

Embodiment
In Fig. 1,2,3,4,5,6: be welded with reinforcing bar 5 in the middle of the disk 4, the hexagonal end welding of the other end of reinforcing bar 5 and screw 6, the threaded end of screw 6 is connected with the anti-collision protection device of crane facility.On the periphery of disk 4, be uniformly distributed with 12-24
wire hole 8, its effect is: wire 10 is fixed braiding software wire nettings 2 through wire hole 8.Software wire netting 2 is cylindric, and the hole count of the wire hole 8 on its cylindric size and disk 4 peripheries all determines according to the polyurethane bumper absorber technical requirements.Software wire netting 2 is to be cut into disconnected wire 10 by size requirement, and wire 10 forms through the 8 fixing braidings of the wire hole on disk 4 peripheries.On disk 4, be uniformly distributed with 6 through holes 7, its effect is: when the cast polyurethane raw material, urethane raw is flow to respectively from through hole 7, software wire netting 2 and preburied iron part 3 are cast in polyurethane elastomer 1.Built-in protecting net formula polyurethane bumper absorber, the surface is uniformly distributed with lobe 9, and its effect is: increase frictional force.
Built-in protecting net formula polyurethane bumper absorber is to form like this: software wire netting 2 and preburied iron part 3 are put into mould together; Cast polyurethane raw material in mould again; Urethane raw flows to from through hole 7 respectively; Software wire netting 2 and preburied iron part 3 are cast in polyurethane elastomer 1; Built-in protecting net formula polyurethane bumper absorber blank with casting forming after 2 hours takes out from mould, then built-in protective net formula polyurethane bumper absorber blank is repaired, and promptly built-in protecting net formula polyurethane bumper absorber has been accomplished.
Claims (2)
1. built-in protecting net formula polyurethane bumper absorber; Comprise polyurethane elastomer (1), software wire netting (2), preburied iron part (3); It is characterized in that: preburied iron part (3) is made up of disk (4), reinforcing bar (5) and screw (6), is welded with reinforcing bar (5) in the middle of the disk (4), and the other end of reinforcing bar (5) and screw (6) are welded to connect; On disk (4), be uniformly distributed with through hole (7), on the periphery of disk (4), be uniformly distributed with wire hole (8); Software wire netting (2) is fixed on the preburied iron part (3), casts in polyurethane elastomer (1).
