The utility model relates to the technical field of coal in Zhanqiao, in particular to light a Zhanqiao closed coal bearing structure, which is characterized in that the steel truss on both sides are respectively fixed on both sides of the coal conveyer belt roller rack and rack middle coal belt conveyor; portal frame bottom beam from the gap penetration between one side adjacent to a vertical bar between the other side of the corresponding adjacent vertical rod gap, and the bottom of the horizontal beam is fixed on the bottom surface of the corresponding truss beam corresponding on the gantry frame on both sides of the lateral pole are respectively positioned on both sides of the vertical rod; the door type rigid frame length along the direction of the horizontal beam a plurality of gate type; located on both sides of the truss frame bottom beam are respectively on both sides of the door type paved trail; the frame respectively by the pressure plate covers the corresponding side of the pole number. Compared with the existing technology, the utility model eliminates the intermediate frame of the belt conveyer belt conveyor, and the steel overhaul on both sides of the truss has no composite floor, so that the weight of the whole structure can be reduced.

一种中承式轻型封闭输煤栈桥结构
本技术涉及输煤栈桥
,具体地说是一种中承式轻型封闭输煤栈桥结构。
技术介绍
火力发电厂的封闭式输煤栈桥结构通常分为“下承式”与“上承式”。“下承式”输煤栈桥,是指以桁架1的下弦及底部横梁12组成承托面形成栈桥桥面,在栈桥桥面上采用中间架5来固定布置输煤皮带机2,并在输煤皮带机2两侧的栈桥桥面上铺设步道6等。“下承式”输煤栈桥的围护结构一般均采用外包式,即利用栈桥的主桁架结构,在其内外侧分别用复合保温板及单层的压型钢板4围护结构封闭,参见图1。“上承式”输煤栈桥,是指以桁架1的上弦及其顶部的顶梁组成的承托面作为栈桥桥面,栈桥桥面上再通过中间架5布置输煤皮带机2,并在输煤皮带机2的两侧的栈桥桥面上铺设步道6等,在栈桥桥面的下方通常还需要设置支撑杆7作为辅助支撑。“上承式”输煤栈桥的封闭结构通常需要在栈桥桥面上间隔固定若干门式刚架3形成轻型结构,并在其外包压型钢板4进行封闭,参见图2。上述两种结构方案,输煤皮带机均需单独在输煤栈桥桥面上设置中间架5来承托输煤皮带机2。“下承式”输煤栈桥中桁架高度通常由通行净空高度要求确定,所以在经济 ...
