In order to solve the technical problem that in the prior art, a traveling crane cannot be applied to a dust-free room, the invention discloses an overhead traveling hoisting mechanism for a dust-free double-beam bridge crane, the overhead traveling hoisting mechanism comprises a traveling vehicle body and a hoisting mechanism, and traveling wheels traveling along a guide groove above a main beam are arranged on two sides of a frame of the traveling vehicle body; the hoisting mechanism is installed at the bottom of the walking vehicle body and comprises a chain hoist, a chain, a lifting hook and an organ type housing, the chain hoist is fixed at the bottom of the vehicle frame, a dustproof housing is installed outside the chain hoist, one end of the organ type housing is connected with the bottom of the dustproof housing outside the chain hoist, and the other end of the organ type housing is connected with the neck of the lifting hook. And the chain connected with the lifting hook is positioned in the organ type housing. Powder or greasy dirt generated in the chain rolling or lowering process falls into the dustproof cover shell and the organ type cover shell, so that the powder or greasy dirt is prevented from being diffused into the air of the dust-free room, and the cleanliness level in the dust-free room is guaranteed.
本发明为了解决现有技术中行车起重机无法应用于无尘室内的技术问题,公开了无尘双梁桥式起重机用上置式行走起升机构,包括行走车体和起升机构,行走车体的车架两侧设置有沿主梁上方导槽行走的行走轮;起升机构安装于行走车体的底部,包括链条葫芦、链条、吊钩和风琴式罩壳,链条葫芦固定于车架的底部,链条葫芦的外部安装有防尘罩壳,风琴式罩壳的一端与链条葫芦外部防尘罩壳底部相连接,另一端与吊钩颈部连接,连接吊钩的链条位于风琴式罩壳内。链条卷收或者下放过程中产生的粉末或者油污掉落在防尘罩壳和风琴式罩壳内,避免了向无尘室空气中扩散,保证了无尘室内的洁净等级。
