Erecting method for catwalk bearing cable of oil and gas pipeline suspension bridge
The invention relates to an erecting method for catwalk bearing cables of an oil and gas pipeline suspension bridge. A first guide connecting device is arranged at a bridge head; a side span bearing cable is used, a first fixing device at the top of a branch tower adjacent to the bridge head is connected with a first guide connecting device on the bridge head, and then side span rope winding is conducted; a mid-span bearing cable is used, the first fixing devices and the second guide connecting devices on the tops of the two adjacent branch towers are connected, and then mid-span rope winding is conducted; during side span rope winding and middle span rope winding, one end of the side span bearing cable is connected with the first fixing device, and the other end of the side span bearing cable penetrates through the first guide connecting device; one end of the mid-span bearing cable is connected with the first fixing device, the other end of the mid-span bearing cable penetrates through the second guide connecting device, and then through cooperation of the chain hoist, the long auxiliary rope and the short auxiliary rope, the rope is pulled and collected multiple times, so that erection is completed on the oil and gas pipeline suspension cable crossing bridge with small dead load, narrow bridge floor and large flexibility. The problems of land occupation and impact caused by arrangement of a winch are solved.
本申请涉及一种用于油气管道悬索桥猫道承重索的架设方法，在桥头设置第一导向连接装置；使用边跨承重索，将与桥头相邻的支塔顶部的第一固定装置与该桥头上的第一导向连接装置相连，然后进行边跨收绳；使用中跨承重索，将相邻的两个支塔顶部的第一固定装置与第二导向连接装置相连，然后进行中跨收绳；使得在边跨收绳和中跨收绳时，边跨承重索的一端与第一固定装置连接，另一端穿过第一导向连接装置；中跨承重索的一端与第一固定装置连接，另一端穿过第二导向连接装置，然后通过链条葫芦、长副绳和短副绳的配合，多次拽拉收绳，以在恒载较小、桥面较窄和柔性较大的油气管道悬索跨越桥上完成架设，解决了因布置卷扬机引起的占地和冲击问题。
