６甲板起货机构造 （Construction of Cargo Crane on Deck） 吊杆和起重机是一般货船上最普遍使用的货物装卸设备，又称为起货设备。吊杆分轻型吊杆和重型吊杆，一般将起重量大于10 t的吊杆称为重吊。重型吊杆与轻型吊杆不同处在于吊杆的头部和根部结构。起重机按动力源不同分为电动式和液压式两种。 6.1轻型吊杆 (a)单桅吊杆装置 (b)门型桅吊杆装置 图6.1.1吊杆装置形式 图6.1.1吊杆装置形式derrick rig type (a)单桅吊杆装置single-masted derrick rig (b)门形桅吊杆装置goalpost-typed derrick device ①千斤索（也称为吊杆顶索）topping lift ②摆动稳索slewing guy ③牵索（稳索）guy ④吊货索cargo fall, cargo rope ⑤吊货钩cargo hook， ⑥绞车winch ⑦舱口围板hatch coaming ⑧上甲板upper deck ⑨舱口hatch，hatchway (10)舷墙bulwark (11)吊杆boom, derrick boom (12)侧柱side post (13)带叉架的桅柱derrick post with forked bracket (14)强力牵索和牵索滑车组 span guy and guy tackle (15)门型桅柱 goalpost (a) 轻型吊杆装置布置 （b）吊杆的牵索 (c) 吊杆的滑车和吊索 图6.1.2轻型吊杆装置构造 图6.1.2轻型吊杆装置构造construction of light derrick rig ①吊货杆桅derrick mast ②吊杆boom derrick boom ③舱口吊杆hatch boom ④舷外吊杆outboard boom ⑤吊杆台derrick stool ⑥吊杆承座derrick socket, gooseneck bracket ⑦千斤座topping bracket ⑧护索环cargo runner guide ⑨吊货索cargo fall, cargo rope, cargo runner (10)吊货滑车cargo block, load sheave (11)上吊货滑车derrick head purchase block (12)下吊货滑车lower cargo purchase block (13)吊杆座滑车derrick heel block (14)千斤索topping lift (15)千斤滑车topping lift block, span block (16)上千斤滑车head span block (17)下千斤滑车lower span block (18)千斤索绞车topping lift winch (19)摆动稳索slewing guy (20)保险稳索preventive guy (21)吊杆间牵索midship guy (22)保险稳索链preventive guy chain (23)吊货钩cargo hook (24)吊货短链short cargo chain (25)三角眼板triangular eye plate (26)吊货网兜cargo net, net sling (27)起货机cargo winch (28)稳索滑车guy block (29)有节定位索 pitched guyline (30)有节定位索夹头 pitched guyline clip (31)舱口围板 hatch coaming (32)起货机平台 winch platform -------------------------------------------------------------------------------------------------- ------------------------------- 图6.1.3 a轻型吊杆头部装置 图6.1.3 b轻型吊杆根部装置 图6.1.3 a轻型吊杆头部装置light derrick head 图6.1.3 b轻型吊杆根部装置light derrick heel ①吊杆箍derrick band ②吊货眼板cargo purchase eyeplate ③稳索眼板guy eyeplate ①吊杆叉头derrick heel ②叉头横销derrick heel cross pin ③
