附 录附录A 英文文献Dump Truck OverviewCompartment is equipped with automatic devices for dumping cars. Also known as dump trucks, construction vehicles, from motor vehicle chassis, hydraulic lifting mechanism, taking the composition of power devices andFreight platform. In civil engineering, often with the excavators, loaders, belt conveyors, such as joint operations, constitute a loading, transportation and unloading production lines, to carry out earthworks, gravel, loading and unloading loose materials transport. Compartment can be loaded automatically as a result of a certain tipping point of discharge, discharge significant savings of time and labor, reduce the transport cycle, increase productivity, reduce transportation costs, and to identify the loading capacity. Transport machinery is commonly used. Engine, chassis and cab of the truck the same structure and general. Can train to the tipping or lateral tipping, through manipulation of the system control rod movement, tipping beyond the more common to promote the piston rod so that tipping inside. A small number of two-way tipping. The allocation of oil by high-pressure valves, tubing into the lifting hydraulic cylinder, inside the front fenders have a driver's safety. Engine through the transmission, hydraulic pump driven from power devices, hydraulic tipping body inside fuel tanks, hydraulic pumps, distribution valves, hydraulic lifting cylinder, control valves and tubing and other components. Hydraulic tipping body inside the tank, pump, distribution valves, hydraulic lifting cylinder, control valves and tubing and other components. Engine through the transmission, hydraulic pump driven from power plant, high pressure oil through the distribution valve, hydraulic cylinder tubing into the lift, push rod so that tipping inside. After tipping more to the common piston rod through the control system to control movement, will enable the train to stop at any position on the need for the tilt. Compartments use of its own gravity and hydraulic control reset. Dump Truck of the main technical parameters are loaded with weight, and marked volume loading. New car or car repair factory commissioning must be carried out so that the process inside a smooth lifting action without strings. Use of the site shall be the right choice of lubricating oil, saving unloading time and labor, the attention of lubrication cycle, lifting oil change schedule strictly. Shipment according to nominal load, overloading is strictly prohibited. Dump truck classification: 1. In accordance with the carrying capacity of the chassis can be divided into series dump truck, dump in tons of series and series of large-tonnage Dump; 2. By the driver dump the form of the bridge can be divided into single-, double-bridge dump, dump eight after the first four, the first four series of ten different models; 3. By unloading the hydraulic lifting mechanism can be divided into different Monacrosporium biparietal dump and dump. Structural analysis of the dump truck: Mainly by the hydraulic dump truck dump bodies, cars, and its annexes constitute the frame. Hydraulic dump them inside the structure of institutions and manufacturers in various different modifications, the following compartments and the lifting mechanism in accordance with the pattern of the two aspects of the structure of that dump truck. 1、compartment type Node compartments by use of different body types can be broadly divided into: general rectangular bucket compartment and inside mine. Ordinary rectangular compartments for the carriage of goods in bulk. Plate with subsequent automatic opening and closing of institutions, to ensure smooth unloading of goods. Ordinary rectangular compartment thickness as follows: pre-board 4 to 6mm, side panels 4 to 8 mm, after the board 5 to 8 mm, bottom 6 to 12 mm. For example: dump truck license ChengLi common standard rectangular compartment thickness as follows: 4 at the end of the first 4 side 8 5. Inside bucket mining is applicable to a larger particle size, such as large stones of goods in transit. Taking into account the impact of goods and touch buildings, mining bucket inside the design of more complex shape, with thicker material. For example:-way power bucket mining dump truck license compartment standard thickness as follows: 6 at the end of the first 6 edges 10, and some models in the floor on some angle iron welded to increase the train capacity of stiffness and impact resistance. 2 、lifting body type Dump truck lifting mechanism is the core of the primary advantages and disadvantages of discriminant indicators truck. Type lifting mechanism common current: F-type lifting mechanism to enlarge tripod, T-style tripod lifting mechanism to enlarge, double lift, the former top-lift and double rollover. Enlarge tripod-type lifting mechanism is currently the most frequently used means of a lift for 8 to 40 tons of dead weight, train length of 4.4 ~ 6 met。
