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 underneath type traveling lifting mechanism for a dust-free double-beam bridge crane, the underneath type traveling lifting mechanism comprises a traveling vehicle body and a lifting mechanism, the traveling vehicle body comprises a frame located between two H-shaped steel beams, and two sides of the frame are respectively provided with a group of traveling mechanisms; a housing extending to the lower part of the H-shaped steel beam is arranged below the frame; the electric lifting hook comprises a chain block, a chain, a lifting hook and an organ-type housing, the chain block is located above the housing, the lifting hook is located below the housing, the chain block is fixed to the bottom of the frame, one end of the organ-type housing is connected with the bottom of the dustproof housing outside the chain block, 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 process that the walking mechanism walks and the chain is rolled up or put down falls into the organ type housing, 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下置式行走起升机构,包括行走车体和起升机构,行走车体包括位于两根H型钢梁之间的车架,车架的两侧各设置有一组行走机构;车架的下方设置有延伸至H型钢梁下方的罩壳;电动吊钩包括链条葫芦、链条、吊钩和风琴式罩壳,链条葫芦位于罩壳的上方,吊钩位于罩壳的下方,链条葫芦固定于车架的底部,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。行走机构行走、链条卷收或者下放过程中产生的粉末或者油污掉落在风琴式罩壳内,避免了向无尘室空气中扩散,保证了无尘室内的洁净等级。
