【正文】 e two separate drive, thus simplifying transmission device, for the spade under the board layout, designed for good results sealed mechanical seal or reducer And shovel plate separation, while achieving automatic overload protection. 3) walk the trackdriven approach and a motordriven motor oil in two ways. Respectively, through mechanical devices or directly from the slowdown in motor oil led the initiative sprocket running track. Mechanical transmission of the walking track, with General Motors will be tracked in two reducer rear, the brake hydraulic braking by mechanical means way. This transmission mode drive high reliability and low prices of motor, easy maintenance, but not speed, slow me larger, Lin Shui major roadway, the motor easily exposed to moisture and burned. Tracked walk to adopt hydraulic transmission patterns, simple system, better performance and advanced technology. Hydraulic transmission of the walking mechanism, in the form choice and hydraulic motor speed control mode design, there are different options. The use of lowspeed torque motordriven, characterized by the system simple, small size, light weight, to achieve stepless speed regulation and automatic overload protection. However, hydraulic motor drive plex, the high cost of manufacturing, maintenance more difficult. Gear used motor oil, the volume of high efficiency, performance and impactresistant, easy maintenance, low cost, a 10 KW around the motor gear oil prices only with the power of the radialSema Da 1 / 10。 2) economic rationality: drive system as simple as possible, fewer ponents and easy processing, low price, easy maintenance, long life。 6) Caozong Tai position should be appropriate, should ensure that drivers easy manipulation, and effort. Instruments showed that the location devices for drivers to observe, not scattered normal operation of the driver39。 4) When all the major ponents designed after. Checking should be carried out, does not meet requirements to be adjusted just so that the focus in track and less than the former center Shaopian L / 6 (L grounding for the track length). In addition, the center of gravity position in the demand for cutting bodies turret after the centerline, and Yuediyuehao high center of gravity to enhance stability when operating machinery. 5) the overall layout should consider the weight of symmetrical left and right and take care of work habits and to facilitate the operation. General driver in the left side of the fuselage and the fuselage in the rear, driver seat height should ensure that the people39。 2) cantilever and spadesuited to the size of relations, not only conducive to loading, to avoid cutting the first shovel cutting board。s seat。 3) estimates plete machine weight and the weight of all ponents requested。英文翻譯：The vertical Boomtype Roadheader design1 IntroductionMechanical design is in the process of product design and an important part of the main links, it is followed in programme design after the design work. The vertical Boomtype roadheader (the roadheader) to the overall design of the merits of plete machine play a decisive role, and the decision of the assembly, the system, coordination between the various ponents of the unity and match, to obtain the highend performance and overall better economic efficiency technology.Roadheader design, including the following:1)According to design project description choice type and various cellular construction pattern2) Decides the plete machine the main technical performance parameter, Including size parameter, heavy parameter, the parameter of movement and the technical economy refer parameter,3) According to system design performance requirement, definite plete machine system position and between them match as well as each part main technical senate parameter,4) The necessary whole, and the mapping of transmission, hydraulic, electronic control systems, and other plans.2 the selected models and various ponents and structural type, drive, and the overall layout of the reasonableIn determining the content, first task should be designed to meet the contents, especially the users of the main demands of the investigation, the two sides exchanged views repeatedly, to satisfy both users (or superior) conditions, can better meet the product development of the overall plan. the selected modelsAccording to roadheader use, for the coal mine tunnel boring or used for other sectors of the works, roadheader working conditions for cutting coal roadway or semiCoal Lane, the pressive strength of coal and rock oneway (or the value of platts coefficient f) and the rock abrasion factor. At the same time the control line should be superscript MT138 ~ 1995 cantilevered Roadheader types and parameters, according to cutting coal and rock the biggest oneway pressive strength, the type of selected models. the structure of the various ponents, the way the driver identifiedRoadheader by cutting general agencies, shipping agencies, walking, hydraulic system, electronic control systems and auxiliary devices (such as dust removal devices, security devices, remote monitoring devices) and other ponents.1) Cutting agencies. Cutting the drive from AC motordriven, in the transmission system located in the general profile coupling with no mechanical overload protection device, the two planets reducer driven spindle front of the cutting head.Some sections of the working bodies boring machine has cut chain, discmilling and cuttingsuch as cantilever. Cantilever due to the cuttingboring machine body flexible, relatively small, can cut a variety of shapes and sections of the roadway, and to achieve selective cutting, but cutting good effect, a higher rate of boring, so now used mainly cantilever Cuttingand has bee boring machine working body of a basic pattern.By cutting head of the layout, is divided into horizontal and vertical axis of the two.
