DM3/3.3-J液缸举升式动力猫道设计与试验

Design and Test of DM3/3.3- J Hydraulic Cylinder Lifting Power Catwalk

为满足小型陆地钻机地面管子堆场与钻台面之间管柱的机械化输送要求,设计了DM3 /3.3-J液缸举升式动力猫道.该猫道采用模块化结构形式,输送臂为细长箱型梁结构,采用高强度钢板组焊;其控制系统采用“远程控制＋本地应急控制” 2 种控制模式,充分考虑了远程控制出现故障后的应急操作.现场试验结果表明：输送臂推移机构、踢出机构、安全防坠落机构及扶正缓冲臂运动合理,满足各种规格管柱的输送要求,猫道带载运行平稳,输送单根总运行用时 50-70s ,在举升过程中按下急停按钮和切断电源,猫道立即停止工作,并保持在当前状态,安全性高,可在ZJ30DB钻机上使用.所得结论可为动力猫道的结构优化提供参考.

The DM3/3. 3 -J hydraulic cylinder lilting power catwalk was designed to meet the demand ol mechanized transportation ol pipes between ground pipe stock yard ol the small land rig and the drill floor surface. The catwalk takes the modular structural style. Its conveying arm uses long and thin box beam structure and is welded by high-strength steel plates; and its control system applies two control modes of “ remote control ＋ local emergency control” that take into lull account of the emergency operation when the remote control fails. The result of field test indicated that thrust mechanism, kick-out mechanism, salety lalloll preventive mechanism and strengthening buller arm ol the conveying arm acted reasonably and satisfied conveying requirements ol pipes in a variety ol specifications. The catwalk operated stably with load and used a total operating time ol 50 -70 s to transport a single pipe. Once the emergency stop button was pressed and power supply was cut ofl in the process ol lilting, the catwalk stopped immediately and kept under the current status, featuring high safety. It could be used lor ZJ30DB rig. The conclusion obtained could be used as a reference lor structural optimization ol the power catwalk.
