Abstract
The utility model discloses a novel constant pressure type rail wheel type guiding device of an amphibious tractor for a railroad and a highway, which comprises rails, rail wheels, rotating pins, check clamping plates, a left swing rod, a right swing rod, wheel axles, oil seals, tapered roller bearings, check rings, slotted nuts, cotter pins, wheel hub covers, lower covers, bolts, lifting oil cylinders and lifting oil cylinder pins, wherein the rail wheels on two sides of the guiding device are respectively arranged on the left swing rod and the right swing rod; the wheel hub covers are pressed into the rail wheels; and the wheel axles are arranged on the left swing rod and the right swing rod through the lower covers and the bolts. In the constant pressure type rail wheel type guiding device, a rear axle of the railway keeps following; and whether the two sides of the rail wheels are uniformly stressed or not or how the road conditions of the railway change, the rail wheels press on the rails at constant pressure so as to be prevented from running off the rails. The rear axle of the railway acts on the rails at fixed pressure and the positive pressure of a vehicle, which is shared by the rear axle, is constant, so that the instability of the positive pressure of a drive axle is avoided.
Description
Technical field
The utility model relates to rail wheel guide piece, is specially novel railway highway double duty tractor constant pressure type rail wheel guide piece.
Background technology
At first the railway back axle is designed to separation type, promptly the rail wheel assembly of both sides links to each other with vehicle frame with independently shipping and reselling on another market respectively, and the rail of both sides is taken turns independently moving separately; Secondly railway back axle hoist cylinder is adopted the mode of hydraulic follow-up, concrete scheme is in multiple directional control valve, an integrated direct-acting overflow valve, the pressure setting of by pass valve is at 1Mpa, being converted to the power that rail wheel acts on the rail level is 1963N, by handling the multiple directional control valve valve rod, realize to railway back axle hoist cylinder level pressure fuel feeding.The Rail Highway double duty tractor is both can be on railway, the special purpose vehicle of the operation of can travelling on highway again.The advantage that it is compared with railway locomotive is: small investment, purchase commodity have only the 1/3-1/5 of railway locomotive, do not need special purpose railway engineering corollary equipment etc.; The utilization cost is low, be equivalent to the operation management cost of automobile or construction machinery and equipment, and consumption of fuel only is 1/2 of a railway locomotive; Railway, highway operation conversion conveniently particularly when railway operation, can descend the road to change the line operation without track switch; One machine can be used more, and function is wide.Also can make railway shunting machine and little running usefulness, it is applicable to Railways Stations section, cave depot, port and pier, industrial and mining enterprises, medium and small goods yard, special warehouse, private siding and local line etc.Install various engineering property facilities additional and become engineering truck, applicable surface is wider and tool is unique, clean facility, circuit cleaning accumulated snow device or the like as the speedily carrying out rescue work of hoisting crane, excavating machine, railroad bridge inspection, electrified contacting nets construction, maintenance, circuit, rescue, tunnel and subway; Also can adopt measures such as explosion-proof, dustproof and unmanned operation to satisfy the needs of special occasions.
Novel railway highway double duty tractor is for adapting to railway, two kinds of road conditions of highway, and car load has four bridges: drive axle, steeraxle, railway propons, railway back axle.When vehicle travelled on railway, car load was by drive wheel, by railway propons, railway back axle guiding.As the rail level injustice, or the distribution of load inequality of vehicle, may cause drive wheel to jolt, and drive wheel is as jolting, then stressed variation takes place in railway back axle rail wheel following closely simultaneously, causes the railway back axle hoist cylinder piston rod rollback that is attached thereto, lifts on the railway back axle wheel, make wheel derailment, cause the slide-out accident.Simultaneously, during vehicle operating, shared the positive pressure of drive axle too much as the railway back axle, will cause drive wheel positive pressure deficiency, skidding appears in wheel.The utility model relates to a kind of guide piece of novel railway highway double duty tractor rail wheel, guarantees the rail wheel with the constant pressure effect in orbit, avoids the derailing of rail wheel.Simultaneously, guarantee that the railway back axle acts on the rail level with constant pressure, avoid the super positive pressure of expectedly sharing drive axle, avoid drive wheel to skid because of positive pressure is not enough.The utility model provides a kind of constant pressure type rail wheel guide piece, can guarantee the railway back axle with the constant voltage effect in orbit, and the rail wheel is fully contacted with rail level, avoids wheel derailment to cause the accident.The railway back axle is chosen suitable oil cylinder cylinder diameter and oil pressure value by calculating during design with the level pressure effect in orbit simultaneously, and the positive pressure that assurance railway back axle is shared is within scope of design.
The utility model content
The technical matters that the utility model solved is to provide novel railway highway double duty tractor constant pressure type rail wheel guide piece, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved realizes by the following technical solutions:
Novel railway highway double duty tractor constant pressure type rail wheel guide piece, comprise rail, the rail wheel, ship and resell on another market, the retaining clamp, left side fork, right fork, axletree, oil sealing, tapered roller bearing, back-up ring, fluted nut, spring cotter, wheel hub cover, lower cover, bolt, hoist cylinder and hoist cylinder pin, the rail wheel of described both sides is loaded on left fork and the right fork by axletree, two tapered roller bearings are housed on the described axletree, one of them tapered roller bearing is by the endoporus step location of rail wheel, another tapered roller bearing is fixed on the axletree with back-up ring and fluted nut, lock with spring cotter, wheel hub cover is pressed in the rail wheel, axletree is loaded on left fork and the right fork by lower cover and bolt, railway back axle left side fork is connected with the car load vehicle frame by shipping and reselling on another market respectively with right fork, hoist cylinder is connected with the car load vehicle frame by the hoist cylinder pin, and railway back axle left side fork and the right fork pin that can rotate respectively rotates under the effect of hoist cylinder.
Beneficial effect
In the utility model, direct-acting overflow valve is integrated in the multiple directional control valve, the realization system is to hydraulic ram level pressure fuel feeding.The utility model railway back axle keeps servo-actuated, no matter whether rail takes turns the both sides unbalance stress, or the track road condition change, the rail wheel is pressed on the track with constant pressure all the time, avoids the derailing of rail wheel.The railway back axle with the level pressure effect in orbit, its vehicle positive pressure of sharing is constant, has avoided the positive pressure instability of drive axle, makes car load have enough deadweights to provide positive pressure to drive wheel, has avoided drive wheel to skid, the car load rideability is reliable.Direct-acting overflow valve is integrated in the multiple directional control valve, has reduced the joint quantity of Hydraulic Elements, the reliability of Hydraulic Elements is improved simultaneously, guarantees the hydraulic efficiency pressure system no leak, and is reliable and stable.
