Abstract

A rubber track is applied to a travelling system of special marsh transporting equipment for oil geophysical prospecting, and integrally formed by connecting a plurality of abreast aluminum rails with three closed annular connecting rubber plates through nuts and bolts. A tensile steel wire and a second iron core are arranged below the connecting rubber plates at two ends, the second iron core is made of a steel plate bent into a hook shape, and two embedded bolts are perpendicularly welded to the outer side of the second iron core. The embedded second iron core, the bolts and the tensile steel wire are integrally vulcanized by means of a die, and the vulcanized second iron core and rubber jointly form a limiting block. A first iron core, bolts and a tensile steel wire are arranged below the connecting rubber plate in the middle and integrally vulcanized through the die, wherein the bolts and the tensile steel wire are integrally welded to the first iron core. The nuts are connected with bolt threaded rods exposed outside the rubber to fix the aluminum rails. The rubber track has the advantages that the rubber track is light in weight, low in landing specific pressure and capable of meeting the requirements of the marsh equipment while travelling in the ground environment of river networks, marshes and the like.

The technical scheme that the utility model adopts is: rubber belt track is connected offset plate through nut, bolt with three closed rings by a plurality of aluminium rails and connects to form whole rubber belt track; Described aluminium rail is a grooved, at the trench bottom of aluminium rail bolt hole is arranged; Described connection offset plate is rectangular annular sulfuration offset plate, connects offset plate and is made up of tension steel wire and rubber layer, and the rubber layer sulfuration is in the outside of tension steel wire; Between adjacent two aluminium rails, there are three annulars to connect offset plate, wherein have two to connect offset plate, a middle part that connects offset plate at the aluminium rail at the two ends of aluminium rail; Be furnished with second iron core below the connection offset plate of at both ends portion; Second iron core adopts steel plate to curve hook solid, and is connected to two pre-embedded bolts at the lateral surface vertical welding of second iron core, under the connection offset plate at middle part, is furnished with first iron core; What first iron core adopted is the oblong steel plate, and is connected to two pre-embedded bolts at the lateral surface vertical welding of first iron core.Second iron core, first iron core, pre-embedded bolt, tension steel wire sulfide through mold integral; Limiting stopper in the middle of first iron core and the vulcanization of rubber form, the cross-sectional plane of middle limiting stopper is an isosceles trapezoid; Second iron core and the vulcanization of rubber form limiting stopper; The thread rod exposed parts of bolt is fixed on the aluminium rail with the nut of screwing and is connected on the offset plate.

First iron core and second iron core are inner at limiting stopper, the transverse force that is used for bearing parts such as caterpillar wheel, crawler belt side-to-side movement during the restriction walking.The tension steel wire vulcanizes in rubber layer, and bears pulling force and equipment load with the rubber layer on the go, realizes walking function.Bolt and iron core are integrally welded to be vulcanized then in rubber layer, is used for fixing the aluminium rail in the outside.

The aluminium rail is the aluminium alloy extrusions that a kind of cross section is grooved, is installed in the rubber layer outside, is used on the one hand and the drive wheel engagement, realizes the transmission of dynamic movement, drives the rubber belt track motion; Contact with ground on the other hand, for the equipment walking provides adhesive ability.Under water environment, can realize the locomotor activity of striking.The width dimensions of aluminium rail and fillet radian and driving gear teeth matching design are realized driving steadily, reduce noise and vibration.

During the rubber belt track combine and assemble, three ring seal rubber belt tracks of aluminium rail and left, center, right are linked into an integrated entity with nut.Drive wheel and aluminium rail are meshed and carry out transmission during walking, and the aluminium rail drives rubber belt track and realizes walking.The aluminium rail is a trench structure, and U type opening is outside, when the walking of soft, hard place table, and aluminium rail ground connection; When landform such as marsh, the network of rivers, the aluminium rail can both contact adherent surface with crawler belt, and grounding pressure is little.Flute profile aluminium rail can be sheared earth, strike, and makes equipment realize walking, has water, the amphibious walking function in land.The width dimensions of U type groove aluminium and fillet radian and drive wheel tooth pitch matching design guarantee to drive the steady engagement of the gear teeth and groove aluminium, have reduced driving noise and vibration.

The beneficial effect of the utility model: the utility model rubber belt track; Can realize equipments in swamp carrying and running gear transmission; Grounding pressure is little, can satisfy the walking requirement of extraordinary equipments in swamp under ground surface environments such as the network of rivers, marsh, improves its driveability and crossing ability.In light weight, have long service life.The aluminium rail is installed in the rubber layer outside, is used on the one hand and the drive wheel engagement, realizes the transmission of dynamic movement, drives the rubber belt track motion; Contact with ground on the other hand, for the equipment walking provides adhesive ability.Under water environment, can realize the locomotor activity of striking.The width dimensions of aluminium rail and fillet radian and driving gear teeth matching design are realized driving steadily, reduce noise and vibration.
