Pipeline pit lifting equipment for road and bridge construction
The invention relates to lifting equipment, in particular to pipeline pit lifting equipment for road and bridge construction. The technical problem to be solved is to provide the pipeline pit liftingequipment, which is characterized in that a worker can descend into a pipeline pit by rotating a rocking handle, and soil around the pipeline pit can be prevented from falling into the pit, for road and bridge construction. According to the technical scheme, the pipeline pit lifting equipment for road and bridge construction comprises a supporting ring, a common frame, a take-up mechanism and a fixing mechanism; the common frame is arranged on the supporting ring; one side of the common frame is connected with the take-up mechanism; and a fixing mechanism is arranged at the lower part of the take-up mechanism. According to the pipeline pit lifting equipment for road and bridge construction, when the worker works in the pipeline pit, the surrounding soil falls into the pit to disturb the work of the worker, and a soil retaining ring can effectively prevent the surrounding soil from falling onto a body of the worker.
本发明涉及一种起降设备，尤其涉及一种路桥施工用管道坑洞起降设备。要解决的技术问题是：提供一种转动摇柄就可以使得工人下降到管道坑洞中，并且可以防止管道坑洞口周围的泥土掉入洞中一种路桥施工用管道坑洞起降设备。技术方案是：一种路桥施工用管道坑洞起降设备，包括：支撑环和共性架，支撑环上设有共性架；收线机构，共性架的一侧连接有收线机构；固定机构，收线机构的下部设有固定机构。本发明涉及当工人在管道坑洞中工作时，周围的泥土掉落在洞中干扰工人工作，挡土环就可以有效的挡住周边的泥土掉落到工人身上。
