Abstract

The utility model relates to an external tyre, which is mainly suitable for large low-speed engineering machinery wheels for fork trucks, road rollers, etc. The tyre provided with an enhanced shielding layer on a tyre surface is characterized in that steel plate strips are arranged at intervals on a yarn layer of the tyre surface, the steel plate strips are provided with steel cogs, and the steel plate strips are connected and fixed by an annular chain-shaped hoop; the chain-shaped hoop is arranged at the cog root of the inner wall of the tyre, and the steel plate strips and the chain-shaped hoop can be movably connected. A rubber layer is covered on the surface of the steel plate strips, the steel cogs are exposed, and a steel plastic composite wearing layer is formed. The tyre can be used for vehicle wheels in cold weather. The tyre of the utility model can prolong service life more than five times, and when the wearing layer is worn or lacerated, a plurality of components can be replaced with convenient maintenance.

Description

A kind of cover tire

The utility model relates to a kind of tire, is applicable to the wheel of large-scale slow speed of revolution construction machinery and equipments such as forklift, roller, also can be applied to automotive wheel below temperature-2 ℃.

Existing forklift, tyre roller, because body is heavy, rubble is many, the work-yard is complicated, cover tire is easy to damage, breach is long greater than 15cm, just can't repair.New tyre generally can only just be scrapped with 3～4 months.The tire price is expensive, generally more than 6000 yuan, specification is big each more than 10,000 yuan.In some bigger building sites, the tire of scrapping is quite a lot of.The perishable not only waste of tire is big, the construction cost height, nor convenient.

The purpose of this utility model is to solve the perishable problems of large-scale slow speed of revolution off-the-road tyre such as forklift, roller, and a kind of novel tire of wear-resisting, long service life is provided.

The technical solution of the utility model is: be provided with the enhancing protective layer on shoe tread, be provided with layer (16～20 layers of yarn) on anodontia cover tire surface, be spaced interconnective steel plate bar on the layer, be welded with steel-tooth on the steel plate bar, replace original rubber tooth, steel plate bar two side ends links to each other with the ring-type chain hoop at lower tire side wall tooth root place respectively by attaching parts, steel plate bar surface coverage one rubber layer, expose steel-tooth, constitute steel glue synergic wear layer.

For flexibly connecting, adopt clasp and hook form between the steel plate bar, also for flexibly connecting, the tread rubber layer both sides fuse rubber layer, steel plate bar, layer with connecting element for steel plate bar two side ends and chain hoop.Flexible connection is that the sidewall face between the steel plate bar is established latch, establishes clasp on the steel plate bar, with between the latch with the hook be connected, one hole is arranged in the middle of the latch, every pitch chain shape hoop middle part has a screw rod to be inserted in the locking plate hole, and with nut locking, every pitch chain shape hoop connects with the button circle.The chain hoop is made of steel bar.

The utility model is compared with prior art, has following good effect: 1. tyre surface has steel glue composite bed, and the gear teeth are steel-tooth, improves tire service life greatly, general available 2 years of this tire, and the more former tire life-span prolongs 6 times; Even 2. there is damage to scratch, only need to change the rubber covering layer of appearance; 3. the gear teeth and attaching parts only need to change the parts that damage, convenience easy to maintenance if any damage; 4. old-fashioned tire does not reach the degree of scrapping as damage, can use this technology yet and set up protective layer, and the saving fund cuts the waste.

Accompanying drawing provides an embodiment of the present utility model.

Fig. 1 is the local protective layer structure scheme drawing that strengthens of cover tire;

Fig. 2 is radially (A to) scheme drawing of cover tire

The embodiment explanation, from Fig. 1, Fig. 2 as can be known, this kind cover tire has 16～20 layers of yarn on tyre surface, also available glue is bonded in conveyor belt material and constitutes layer 13 on the old tire of worn-down, arrangement (axially) evenly and at intervals has steel plate bar 1 on the layer, steel plate bar two side ends is provided with clasp 2, and every block plate has 8 of clasps, and hook 6 connects steel plate bar 1.Microscler steel-tooth 5 is arranged on the steel plate bar, and steel-tooth is welded on the steel plate.Sidewall face between the steel plate bar has latch 4, and there is clasp the latch both sides, and there is circular hole the centre.Steel plate bar and latch 4 usefulness 3 oblique connections of hook.Having a hole, every pitch chain shape to bind round 8 middle parts in the middle of the latch has screw rod 10 to be inserted in latch 4 holes, locks with nut.Chain hoop 8 is positioned at tooth root place, tire both sides, and every pitch chain shape hoop connects with button circle 9.The chain hoop is made of Φ 12～Φ 18 steel bars.Hook 3,6 usefulness Φ 10～Φ 14 steel bars are made.

Steel plate bar surface coverage one rubber layer 7, at steel-tooth 5 place's openings so that expose steel-tooth.The tread rubber layer both sides fuse rubber layer 7, steel plate bar 1, layer 13 with connecting element 11, tighten with nut 12.

Because steel plate bar, chain hoop, rubber layer all adopt flexible connection, the stressed irregular influence of yet not having in tire a part can not damage; It is also convenient to use with the passing of time certain failsafety to change.

For making this technology be applied to automotive wheel, establish the arc backing plate in cover tire layer 13 upper steel plate bar positions, establish oblique heat radiation guide duct between arc backing plate and the steel plate bar, this design ventilation and heat is good, can be applicable to automotive wheel in freezing sky.
