鳞板输送机设计

摘 要

鳞板输送机是由一系列支承在滚子链上相互搭接的金属磷板形成 以个连续移动的工作面来载运散装固体物料的输送设备。 磷板输送机 有水平型、倾斜型、水平倾斜型三种机型，其工作原理基本相同，物 料的移动是靠磷板载运而形成。鳞板输送机机构简单、适用范围广、 输送能力搭、运行阻力小、安装维修方便、使用寿命长。它不但能水 平输送，也能倾斜输送；能多点加料，设备工艺布置灵活。鳞板输送 机可用于沿水平或倾斜方向由储仓向破碎机、输送机或其它工作机械 输送各种块状或松散物料。有轻型和中型之分。

鳞板输送机是一种挠性牵引的连续输送机械，是为采煤工作面和 采区巷道运煤布置的机械。它的牵引机构是鳞板链，承载装置是运输 机，鳞板链安装在运输机的槽面。运输机沿运输路线全线铺设，鳞板 链绕经机头、机尾的链轮接成封闭形置于运输机中，与滚筒采煤机和 输送机推移装置配套，实现落煤、装煤、运煤及推移输送机械化。沿 输送机全长都可向溜槽中装煤，装入运输机中的煤被鳞板链拖拉，在 运输机内滑行到卸载端卸下。

鳞板输送机在使用中要受拉、压、弯曲、冲击摩擦和腐蚀等多种 作用，因此，必须有足够的强度、刚度、耐磨和耐腐蚀性。由于它的 运输方式是物料和鳞板链都在槽内滑行，因此运行阻力和磨损都很 大。但是，在采煤工作面运煤，目前还没有更好的机械可代替，只能 从结构上、强度上和制造工艺上不断研究，使它更加完善、耐用。

Abstract

Scales conveyor overlap each other by a series of supporting roller chain metal phosphorus plate to form a continuous movement of the face to the carriage of solid bulk materials conveying equipment. Phosphorus conveyor horizontal, inclined and horizontal tilt in three models, and its working principle is basically the same, the movement of materials formed by phosphorus plate carrying. Scales plate conveyor institutions, applicable to a wide range of transmission capacity to take small running resistance, easy installation and maintenance, long service life. It not only can the level of transmission can also be inclined conveyor? more feeding equipment process layout flexibility. Scales conveyor can be used to transport a variety of block or loose materials along horizontal or inclined direction from the storage bunker to the crusher, conveyor or other machinery. There are points of light and medium.

Conveyor scales is a flexible traction of the continuous conveyor

machinery, the mechanical layout of the coal of the coal face and Roadway. Traction is a scaly plate chain, the carrying device is a transport aircraft, scaly plate chain installed in the transport plane of the groove face. Transports across the board laying along the transportation routes, scales plate chain around by the nose, tail sprocket connected to the closed form placed in the transport plane, with the drum shearer and conveyor passage of equipment and supporting facilities to achieve a fall of coal, coal loading, coal and the passage of transport mechanization. Along the conveyor length can be coal to the chute are installed, load transport aircraft in the coal scales plate chain drag, remove the side in transport aircraft taxiing to uninstall.

Scales conveyor in use tension, compression, bending, impact friction and corrosion and other role, therefore, must be of sufficient strength, stiffness, wear and corrosion resistance. Since its mode of transport for materials and scales plate chain sliding in the slot, running resistance and wear. However, in the coal of the coal face, there is no better machinery instead of only from the structure, strength, and manufacturing processes continue to study and make it more perfect and durable.

Keywords: conveyor scales board? head assembly? drive assembly? transport aircraft

前 言

鳞板输送机是一种挠性牵引的连续输送机械，是为采煤工作面和

采区巷道运煤布置的机械。它的牵引机构是鳞板链，承载装置是运输 机，鳞板链安装在运输机的槽面。运输机沿运输路线全线铺设，鳞板 链绕经机头、机尾的链轮接成封闭行置于运输机中，与滚筒采煤机和 输送机推移装置配套，实现落煤、装煤、运煤及推移输送机械化。烟 输送机全长都可向溜槽中装煤，装入运输机中的煤被鳞板链拖拉，在 运输机内滑行到卸载端卸下。

鳞板输送机在使用只能感要受拉、压、弯曲、冲击摩擦和腐蚀等多种作用， 因此，必须有足够的强度、刚度、耐磨和耐腐蚀性。由于它的运输方式是物料 和鳞板敛都在槽内滑行，因此运行阻力和磨损都很大。用鳞板输送机运输散碎 物料的方式出现于工业发达的国家。早期的鳞板输送机长度只有几十米；功率 小，牵引链的强度也不高。经过多年的改进和发展，目前综合采矿用的鳞板输 送机除了运煤之外，还有很多功能。鳞板输送机在综合采煤工作面与采煤机和 液压支架配套工作。
