horizontal and vertical axis of the two. The linecutting head of the advantages are: Transmission convenient, pact and can be cut to any shape of the profile, easy access to the formation of a crosssection and is conducive to expansion in the use of cantilever, or ditch digging, in Waterloo. Cutting head the shape of a cylindrical, cone and the cone and cylindrical, as the latter two cutting head to drilling, and the cutting surface than the formation, use it more. This is the work of the shortings: As the longitudinal axis of cutting head in the horizontal swing at the cutting reaction force is not passed machine centres, with cantilevered form of torque to boring machine have a greater vibration, stability is poor. Therefore, the coal roadway excavation, the need to increase the body weight or support the installation of auxiliary equipment. At present, such a boring machine in some sections of the use of more boring machine. 2) Shipment of bodies. It generally from the middle loading and conveyor ponents. They were driven or focus may be linked, either by AC motor drive, can also be used hydraulic motor drive. Trailing clawis to use a turn moves the rake claws to continue to rake materials and in a reprint from transport operators. This structure is simple, reliable, small form factor, loading good effect, the application is widespread. However, such institutions loading width restricted (because boring machine running track when agencies generally do not arouse). To expand the loading width, will shovel the entire harrow board, together with the claw agencies in the level of swing, or design dual rake claws, to expand the scope of loading. Institutions than the rakewheelclaw simple, high intensity, reliable, but with less bulk materials. Loading agency programme is not only the installation of the clawrakewheel can also be installed, the two can be used interchangeably. Usually, the choice rake clawloaded, but considering loading width of the problem, may choose to double rake claws, can also be designed to rake clawround interchangeable with the loading mechanism. Some sections boring machine use of scraper chain conveyor agencies. Transportation agencies are generally undertaken by the tail to the nose tilted upward direction of the layout. Transportation agencies can be the driver, is about to motor or hydraulic motor and reducer layout in the scraper conveyor and around the side of the fuselage, the body in the driver loading at the same time, indirectly, to transport bodies to take the initiative to the tail shaft driven scraper Transportation agencies. This drive system ponents in small, relatively simple bodies, but loading and transportation agencies involved in the two campaigns, mutual influence. As the location less space layout more difficult. Transmission organizations to adopt an independent driver, is about to motor or hydraulic motor layout away from the machine side, driven by slow delivery agencies. This mode of transmission drive layout simple, and filling the campaign Hubuyingxiang. However, due to transmission and more dynamic ponents, the point of failure has increased. At present, the two transportation agencies are used, as appropriate, the design should be identified. General loading and institutions often use the same drive. Loading agencies can use motordriven, can also be used hydraulic motor drive. However, in consideration of the working environment and wet with mud, optional hydraulic motor drive for good. 3) Run institutions. Walking agencies tracked the general pattern, crawlerrun institutions apply to the floor is uneven or soft conditions, no road track laying. Traction with large capacity, good mobility, reliability, flexibility and mobility on the floor adaptability of the advantages of good. But its plex structure, ponents and wear more serious. At present crosssection of the boring machine is usually used crawlerrun institutions. Walking agencies tracked the general pattern, the two tracked separately by the respective power to drive, to achieve in situ. Caterpillar is the driving force of two motors and hydraulic motors, motor driver is generally set up a walking speed, hydraulic motordriven large lowspeed torque motor can be driven directly tracked sprocket, or used in the hydraulic motor speed Reducer led the drive sprocket track, it can achieve Promise governor. Tracked structure of a sliding and rolling two, when the speed machine to mobilize ≤ 10 m / min in the light Roadheader, should adopt the structure of sliding when the mobilization of speed machines 10 m / min of heavy, severe Roadheader should be used Rolling structural type. 4) The hydraulic system. Hydraulic systems use of openway valve system more centralized control (direct or remote control manipulation) way. Domestic and foreign use of the past, gear pumps, hydraulic system in recent years Roadheader used piston pump have increased the trend. 5) Electronic control system. Electronic control systems, including some power, control and inspection of the part. Electronic control system must be in accordance with the requirements of coal mine explosionproof design, manufacture, testing, GB38362020 must meet the standards of the relevant provisions and requirements. In order to improve operations at the Roadheader in the security, operational flexibility and mechanical transmission part of the fault diagnosis and monitoring functions, from the practical point of view, the installation of the necessary machines from a remote control device, monitoring pressure, temperature, level and key parts the fault diagnosis device. Layout General layout of the contents include the following: 1) Identify the ponents in plete machine said the location, shape and size of the request。 2) To identify the parts, ponents。
