【正文】 , to expand the width of unloading. running track and identify the technical parameters of connectivity between a)walking track drivers and transmission patterns have the following two ways, the overall design and layout determined at the time one of them. 1) Drive a motordriven than reducer (i ≈ 250) → led。 ~ 25 176。.2) Cutting the link .Cutting agencies cantilever Chaxinginstalled in front of the fixedChaxing rotary table, the turret to the rack. According to cutting agencies in the course of operating the force and torque, the application of MT4751996 cantilevered Roadheader rotary bearing type, the basic parameters and technical requirements selected rotary bearing the structural type, determined by calculating slewing ring size specifications. If the user does not require a cantilever stretching structure, is generally not remended. shipping agencies determine the parameters 1) Loading mechanism Loading bodies and Middle conveyor used linkage or singleaction mode, loading the bodies rake claws speed is generally 25 ~ 48 r / min. Star Ferry39。 ( ~ ) Pv, this force should be no larger than the floor slippery track at the limits of traction. technical and economic indicatorsQ = (m3/min), in the sxcutting head for the vertical cross sectional area, m2: Vn for the cutting head of cutting swing speed, m / min.Roadheader designed life, in the international advanced products up to 3 to 5 years, during which the need of major repair or wells, the general domestic product for 1 to 2 years.4 in accordance with design requirements. Determine the parameters of the main ponents and their relationship between the connector cutting agencies and technical parameters of the established link between1) Cuttingagency technical parameters of cutting the head with the general pick for the doubleheaded or three spiral layout. Cutting head speed n = 20 ~ 65r/min, a sharp pick cutting the average speed V = ~ / s, cutting swing speed Vn = ~ l0m / s. Cutoff line from t = 20 ~ 50mm, (when cutting coal from the value of alltime for small value). Average singlepole/doublethrow force should reach: f4 grade coal and rock F ≥ 2500 N, f6 grade coal and rock F ≥ 5000 N, f8 grade coal and rock F ≥ 12000 N, pick the best angle for the installation of 45 176。 Rcp cutting head for the average radius。 muddy for the water to soften the shale bottom, p ≤ MPa. movement parametersCutting the movement parameters: cutting head of the average cutting speed V: on the oneway coal and rock pressive strength of 40 MPa, V = 3 ~ / s。 V for the cutting head on average cutting speed, m / s。 weight parameter, parameter of movement and dynamic parameter. size parametersComplete machine length, width of the size directly related to its turning radius, Remended lightlength ≤ m, mediumlength ≤ m, heavy machine ≤ l0m, the corresponding width were ≤ m, ≤ m, ≤ 3 m. The plete machine relates its tendency, the static stability highly directly, the adaptation scope and passes quality, therefore lower better. The current development trend of Chinese and foreign models is the dwarf models, medium and heavyhigh ~ 2 m, special light, light machine the height of ~ m. Roadheader to dig the biggest section of roadway, the minimum height and width should be designed to meet the requirements of the mission. Undercover depth of 250 ~ 400 mm, ground clearance C = B/13 +84 (mm), B for the two track distance). Middlelong conveyor entrance to the expected high degree of the best 400 mm, length of track ground with the center distance L B ratio for L / B ≤ . weight parametersThe plete machine dead weight is the mechanical roadheader an important parameter, the engine weight too is light, the work stability drops, when swinging cutting can occur fishtails the phenomenon, the cutting efficiency drops, truncation tooth rate of wear increase。 4) adaptation: the drive system ponents should be adapted to load, working conditions and environmental conditions of the request. Agencies to the transmission system requirements and the choice of transmission patterns .Boring machine cutting, loading, transport, walking and other institutions generally are respectively transmission, all parts of the state and subject to different working conditions, thus driving patterns have different requirements. 1) institutions require a greater shortterm Guozainengli, motor oil is very sensitive to the impact load, the loading capacity of lowimpact cutting head for normal functioning. Therefore, the boring machine working body should adopt the motordriven mechanical transmission type. Should make use of small size, power, a strong capacity for electric motors, and equipped with reliable electrical protection device. According to the pact body of work features, usually work in the reducer cantilever, an integral part of a cantilever. Cutting the first governor general way with a round peg for the method of transmission organizations to simple. 2) rake with institutions transmission device is characterized by: reducer be installed in the limited size of the lower part of the shovel plate, thus design a smaller space, poor working conditions. Reducer often soaked in muddy coal and rock in the cards when the material easy to overload. Trailing equipment, transportation agencies the use of mechanical transmission, for the larger motor, not the end of the conveyor installation, the shovel is generally installed on both sides of the board two motor, with a rake, a mon power transmission organizations, such bound to make the Slowdown me the size of the increase in the spade under the board layout more tense. In addition, consider the claw and rake boards linked linked overload situation, to protect the motor did not burn, the general needs of internal security in reducer frictionclutch. Trailing equipment, transportation agencies the use of motor oil transmission gear, as small size, light weight, will enable th
