Description
Technical field
The utility model relates to slag case transport trolley, but particularly a kind of slag case transport trolley of disengagement type.
Background technology
Domestic steel plant handle the general following several method that adopts to slag:
1. adopt slag ladle to connect slag, the slag train is transported to the unloading of slag field by industrial railway, and railway is crisscross steel mill in, has not only influenced the unimpeded of on-site traffic, and railway lays and occupied large stretch of industrial place, and this kind mode mostly is the employing of old steel mill.
2. the Baosteel converter slag is loaded by huge slag ladle, make short-range linear running to the tray workshop through electronic slag ladle chassis, slag ladle is sling and slag is unloaded to tray by driving, trickle cooling subsequently, by tray slag is dumped to special-purpose railway carriage again, be transported to tank again, further cooling, the slag in the tank is by grab bucket entrucking outward transport.This kind method has fewer environmental impacts, but complex process, equipment investment is big, and general steel mill is difficult to imitate.
3. steel mills such as China's Baosteel, Wuhan Iron and Steel Plant adopt the slag ladle transport trolley of no rail wheel type, the slag of transportation electric furnace steel making, Baosteel has been introduced the slag ladle transport trolley of 35 tons, 40 tons, 50 tons, 60 tons various models of load-carrying from Japan, moral figure, the U.S., and with homemade 35 tons, 45 tons slag ladle transpories trolley of research institute's cooperation research and development, Wuhan Iron and Steel Plant has also been introduced the slag ladle transport trolley from Spain.Tianjin Steel Pipe Corp. and Taiyuan Iron ﹠ Steel Corp introduce the slag ladle transport trolley of German KAMAC model, and the Nangang and the steel that continues adopt homemade 35 tons of slag ladle transpories trolley etc.The employing of slag ladle transport trolley has overcome the deficiency that railway is mucked haulage, and maneuverability, the efficient height, by external numerous steel mills are adopted, but because the high fault rate that is difficult to overcome that the mode of operation of slag ladle transport trolley is brought and the high price of slag ladle transport trolley make the numerous steel mills of China hang back to adopting the slag ladle transport trolley.For 80～100 tons of electric furnaces, minimumly should be equipped with 3～4 slag ladle transpories trolley.Because the price of 35 tons～45 tonnes of slag ladle transpories trolley of import is up to 400～5,000,000 yuan/, therefore domestic some steel mill only disposes two import slag ladles and carriages.For example China steel mill introduces 50 tons of slag ladles and carriages of 2 KAMAG, because the direct prestige of problem that breakdown of equipment and reparation brought is assisted the continuity of STEELMAKING PRODUCTION, steel mill's no fund again buys more slag ladle transpories trolley as emergency vehicle, so some once adopted the steel mill of slag ladle transport trolley to abandon the slag ladle transport trolley gradually, being compelled against one's will, (slag directly sprinkles on the ground under the electric furnace stove hot application slag technology that changes serious environment pollution into, the trickle cooling, use caterpillar loader to lorry loading then, fortune removes slag again), the trackless technology of mucking haulage faces major defeat in China.
Existing slag ladle transport trolley has two big classes: a class is the unit frame structure, the front-wheel hydraulic power-assisted steering.Another kind of is the articulated car body structure, and car load is made up of front vehicle body and aftercarriage two parts, be articulated and connected between the car body of front and back, by hydraulic steering gear, turn to oil cylinder make before and after the car body articulated steering.Owing to be articulated car body, therefore can obtain the turn radius littler than the slag ladle transport trolley of unit frame structure.
The double-arm operating mechanism of slag ladle transport trolley is arranged in rear vehicle, and its hinge-point is on the vehicle frame of car body tail end.When hydraulic ram pushes the work forward mechanism when turning near level attitude, the fork ear on operating mechanism top just can lift by crane bearing pin near slag ladle, the slag ladle and carriage reverse travel, operating mechanism's fork ear fork is held slag ladle lifting bearing pin, oil cylinder piston bar withdrawal then, make operating mechanism finish gyroscopic movement more forward, slag ladle then breaks away from ground and gives rise on the aftercarriage workplatform, finishes the tinning action.This is the specific mode of operation of slag ladle transport trolley.
The front vehicle body of the slag ladle transport trolley of articulated car body is provided with driver's cab, the power drive of operating part, f-w-d and hydraulic power unit etc., only is the tire of BOGEY WHEEL in the aftercarriage setting.
The slag ladle transport trolley of unit frame mostly is front-wheel steering, middle rear-axle drive, middle trailing wheel be load-supporting wheel be again drive wheel.
Because during slag ladle transport trolley reversing dress slag ladle, operating mechanism must make gyroscopic movement backward, during extremely near level attitude, just can make operating mechanism's fork ear near slag ladle, therefore when playing jar, because heavily loaded slag ladle and operating mechanism's weight have formed huge tilting moment, so all slag ladle transpories trolley must be provided with support oil cylinder at the aftercarriage afterbody, when rising jar and unloading jar, support oil cylinder support ground, support car body whereby, back axle and middle trailing wheel damage because of stressed in avoiding.In order to make balancing torque, must increase complete vehicle weight and counterweight is set foremost simultaneously at vehicle greater than capsizing moment.The slag ladle transport trolley of 35 tons of load-carryings for example, the car load deadweight is general, and heavily loaded car load gross weight is about about 65 tons all at 30～32 tons, and it has not only increased equipment cost, and the road pavement quality has also proposed strict demand.
Owing to need fork dress slag ladle, so the slag ladle transport trolley all adopts double-arm operating mechanism, this just requires two working arms of operating mechanism to be synchronized with the movement, otherwise will cause connection crossbeam torsional deflection or fracture between operating mechanism's both arms, even heavily loaded slag ladle is turned over to an inclination, cause and sprinkle slag and causing the serious consequence of burning car and personal injury thus.
Usually adopting increases operating mechanism's rigidity and intensity and adopts measure such as flow divider-combiner in hydraulic efficiency pressure system, guarantee being synchronized with the movement of the two working arms of operating mechanism, but because the fault of hydraulic efficiency pressure system element or the impurity in the fluid make faults such as spool blocks, even the formed torque failure power of asynchronous motion of two φ 280～320mm cylinder diameter oil cylinders also can't be born by reinforced double-arm operating mechanism.
The slag ladle transport trolley adopts hydromechanical drive, promptly adopt turbine transformer one hydraulic pressure manual transmission, the great advantage of hydraulic transmission is its software feature, and software feature is absolutely necessary to front loader, this class machinery of bulldozer, but for the slag ladle transport trolley, its advantage is then not remarkable.Efficient is low to be its maximum shortcoming, and to geared wheel, net effciency generally only is about 0.64 from diesel engine.The major failure of slag ladle transport trolley appears at two large parts, and the one, because heavy duty and abominable service conditions make the hydraulic efficiency pressure system component abrasion and cause various faults thus, cause operating mechanism's distortion, parts damage etc. thus; Another is the various faults of easy appearance such as sealing member, Transmission and power-transfer clutch in the hydraulic transmission system.
Because the mode of operation of slag ladle transport trolley and the formation of driving system have determined general layout, overall structure and the construction parameter of slag ladle transport trolley basically, thereby have also caused the high manufacturing cost and the high price of slag ladle transport trolley, and high service expenditure.
