Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1 and Figure 2, a kind of telescoping auxiliary cargo boom, comprises auxiliary fundamental segment 10, auxiliary slip joint 11, luffing arm-tie 12, oil cylinder bolt mechanism 13, auxiliary head pulley 14; The end of auxiliary fundamental segment 10 is provided with oil cylinder bolt mechanism 13, oil cylinder bolt mechanism 13 connects luffing arm-tie 12, auxiliary slip joint 11 is flexible in auxiliary fundamental segment 10, auxiliary slip joint 11 saves knock hole arm being arranged and locates with auxiliary fundamental segment 10, auxiliary slip joint 11 is located by oil cylinder bolt mechanism 13 and auxiliary fundamental segment 10, and auxiliary head pulley 14 is arranged on the top of auxiliary slip joint 11.
As shown in Figure 3, oil cylinder bolt mechanism, comprises arm guide 15, arm pin 16, latch spring 17, the hydraulic ram 18 that can reset, proximity switch 19, nylon slide block 20 and detects block 21; Arm guide 15 is fixed on auxiliary fundamental segment 10, arm guide 15 is provided with through dowel hole 22, arm guide 15 outside is provided with the hydraulic ram 18 that can reset, can the reset cylinder bar of hydraulic ram 18 and arm pin 16 is threaded connection, arm pin 16 top is provided with latch spring 17, arm guide 15 and auxiliary slip joint contact surface are provided with nylon slide block 20, and arm guide 15 is provided with proximity switch 19, detect block 21 and are arranged on the joint arm of auxiliary slip joint knock hole side.
