The utility model is characterized in that ear rings arranged on both sides of an integrated endless-track plate provided with a dismountable rubber friction block are fixedly connected with two close links positioned on the edges of both sides of the tyre through a rod end joint bearing; the endless-track plates which are mutually lapped are uniformly and tight sheathed on the outer circumference of the tyre to form a tyre protector. The utility model is capable of effectively preventing the tyre from being worn, punctured and hacked, increases the service lift of the tyre, the operational reliability, the tractive property and the productivity of the machine, enhances the operating stability of the vehicle and extends the range of use of the wheeled engineering machinery.
Description
The utility model relates to a kind of apparatus for protecting tyres, especially for the tire protection rubber-metal track device of engineering machinery vehicle.
Tire is a consumable accessory, and its resistance to abrasion is low, anti-thorn cut wound poor performance, and the life-span is very short, and particularly under the mine operation environment, the general life-span only is 500-2000 hour, and the tire operating costs accounts for the total operating costs of machine up to 48-60%.In order to increase the service life, reduce cost of tires usefulness, up to the present, apparatus for protecting tyres is nothing more than two kinds in the world: first protection link network.Its two be the protection crawler belt.
The tire protection link network is combined into link network by many chain pieces, chain link by the definite shape connection and is rolled in the tire outside.Noise is arranged during work, and the relative tire of link network has slippage, loose, and finger stone easily enters in the net in addition, increases wear on tyres, link network cooperated pine with tire, can influence capacity rating, even can not work, and cooperated tension, then the link network overtension can quicken the link network wearing and tearing, reduces its life-span.Protection link network optimum racing slick is not suitable for installing to dapple tire and the tire of deepening decorative pattern, can cause that the decorative pattern Root Stress concentrates, even gets rid of pattern block and make tyre injury, and in addition, protection link network tensile force is difficult for adjusting.
The tire protection crawler belt is to wrap up in a crawler belt in the tire outside, constitutes crawler belt tread tire.At first be applied to CAT988 type loader by the U.S. long Te Bile company, its structure is that tire protector central authorities have a circle criss cross groove, the criss-cross projection that is fixed by bolts on the caterpillar block is embedded in the groove, and each caterpillar block is linked to be the periphery that the osed top polygon wraps in tire through the chain rail joint of tire both sides.This device needs special tyre, the expense costliness, and commonality is poor, can not adjust the predetermincd tension between crawler belt and the tire, and the installation and maintenance inconvenience, the force structure of rail chain hinged place is bad, pin and guide life-span are lower, install crawler belt rear tyre formula advantage additional and reduce to some extent, and manoevreability reduces.
The purpose of this utility model is that a kind of improved tire protection rubber-metal track device will be provided; it can prevent wear on tyres, anti-puncture, anti-cut wound effectively; improve tire service life; reduce the tire operating costs; improve the tire working reliability; improve machine productivity, vehicle operation stability and vehicle towed performance, enlarge the range of use of wheeled construction machinery.
The purpose of this utility model is achieved in that the integral type three muscle caterpillar block both sides earrings that removable rubber friction piece is installed are hinged with bearing pin and spherical plain bearing rod end; and be connected so that conical surface positioning threads is fastening with the chain link that is the closed polygon shape that is positioned at tire both sides outer rim respectively by the screw rod of spherical plain bearing rod end; produce elastic deformation by screw clamp bearing up pulley tire; make to produce between caterpillar block and the tire to clamp and adhere to friction force, thereby make the caterpillar block of mutual overlap joint wrap tightly formation apparatus for protecting tyres equably at the crown place of tire excircle.
The utility model is owing to organically used both sides to have the parts such as integral type three muscle caterpillar blocks, spherical plain bearing rod end, removable rubber friction piece and enclosed ring of earrings; thereby overcome the functional defect of original protection crawler belt, have outstanding substantive distinguishing features and significant technological advance.This utility model is compared with prior art and is had the following advantages:
1, novel structure is simple, compact, is easy to make, and cost is low, is easy to installation and maintenance, and is safe and reliable, do not need special tyre, applied widely.
2, because entire track plate both sides have earrings, and be fastened and connected by spherical plain bearing rod end and the sealed joint link that is positioned at the tire both sides, so crawler belt is installed the back with the tire combination firmly, has predetermincd tension to a certain degree, have good adhesion value along tire circumferential direction, can side direction not come off simultaneously.
3,,, caterpillar block clamps so can installing on vehicle under the inflation of tire state immediately because the screw rod of spherical plain bearing rod end is connected by clamp nut with the chain link, and screw rod clamps with conical surface location mutually with the chain link simultaneously; Screw rod and chain link location are convenient and reliable, by installing the taper pad additional at conical surface place, can realize the adjusting of the degree that clamps between caterpillar block and tire.
4, be positioned on the spherical plain bearing rod end by earrings is hinged owing to the entire track plate, along the tire excircle uniform and mutually the overlap joint and totally-enclosed, and removable rubber friction piece is installed in the caterpillar block outside, so, can be anti-attrition effectively, thorn, cut wound tire protector and sidewall, prolong its service life, improve its functional reliability, simultaneously, do not reduce the manoevreability of rubber-tyred vehicle, be adapted to various road surface work environments for use, enlarge the machine range of use, can change rapidly after the friction shoe wearing and tearing, therefore, can reduce the tire operating costs significantly.
5, owing to adopt spherical plain bearing rod end, make the caterpillar block degree of freedom increase, caterpillar block eliminated " polygon effect ", thereby rolling resistance is little along circumferentially freely rotating around ball pivot point; Avoid the movement interference between caterpillar block and the chain link at steering state or along tire cross direction load when inhomogeneous, improved chain link pin and guide life-span.
When 6, behind inflation of tire, installing under the free state, the ball pivot center-point that each caterpillar block earrings is connected with spherical plain bearing rod end is positioned on each chain link hinge-point place circumference or its inboard, thereby guarantee the relative displacement minimum that tire protector and caterpillar block inside face are produced when tire load-bearing ground state, make treadwear extremely small.
7, after on the tire the utility model device being installed, machine gravity is reduced, increase vehicle operation stability; Simultaneously, it is big that ground contact area becomes, and grounding pressure reduces, and has improved adhesion value, improves vehicle soft surface crossing ability; Because caterpillar block is equivalent to ballast, can produce additional tractive force, has improved vehicle towed performance and capacity rating significantly.
