电动吊篮前横梁坐落在悬挂机构的前支架上,而前支架的马鞍和前横梁的连接是两条M14螺栓,前支架升降部分的支撑还是靠两条M14螺栓支撑。前横梁和前支架的各两条M14螺栓如果能均匀受力,再从承重链往前看,电动吊篮的整个受力链上也不存在问题。但受到加工精度的限制,此两处的螺栓实际受力也只是M14一条螺栓所承受的载荷。由于平安绳与吊篮架体的连接,因为绳均采用直径不小于φ13mm钢丝绳通长到底布置。正是平安绳的安全使用,才使得电动吊篮有了安全性的保障。 电动吊篮利用钢丝绳兜出吊篮架底与保险绳卡牢(少4扣)每卡一次留有不大于是1m升降量,吊篮万一从承重钢丝绳或钢丝链杆上脱落,平安绳就起到吊住吊篮架的作用。如果采用钢筋链杆作承重吊杆,则先把安全绳与钢筋链杆挂在已固定好的屋顶挑梁上,然后,把倒链挂在钢筋链杆的链杆上下部吊住电动吊篮,利用倒链升降。因为倒链行程有限,因此在升降过程中,要多次倒替倒链,人工将倒链升降,如此接力升降。
中译英: Electric basket front cross member located in the linkage of the front bracket, and the bracket of the saddle and the front cross beam is connected with the two M14bolts, the front bracket lifting part support on two M14bolt support. Front beam and the front supporting frame of the two M14bolts if can even force bearing chain, from look forward, electric basket the force chain does not have the problem. But affected by the processing accuracy constraints, the two bolts of actual stress is only M14a bolt load. Due to safety rope and the basket frame connection, because the rope with a diameter of not less than13mm diameter wire rope length is arranged. It is safe to use safety rope, which makes the electric basket with security safeguard. Electric basket using wire rope around a basket frame bottom and the safety rope clamping(at least 4BUCKLE)each card once left not greater than1m lifting weight, basket case from bearing wire rope or wire chain bar shedding, safety rope hanging basket frame plays the role of. If using the reinforced rod chain load-bearing suspender, then put the safety rope and reinforced bar chain hanging in the fixed roof beam, and then, the chain hanging on a steel link chain bar lower hanging electric basket, using the chain lift. Because the chain travel limited, therefore in the lifting process, has to replace the chain, the chain of artificial lift, so the relay lifting. (图/文http://www.chinaketong.cn) |
