A load-turning device for slag box of double girder gantry crane
During shield construction of urban rail transit, before shield tunneling starts, the construction of sludge pit and installation of double girder gantry crane are generally completed. As a double girder gantry crane for shield tunneling, it is designed with a dumping device of shield slag soil transport slag box. However, with the development of the city, the locations of some subway ports are limited, the traffic of people and vehicles is large, and the construction progress is slow. As the station construction is just starting, there is no space for the planning and construction of sludge pits. The double girder gantry crane used for vertical transportation of shield sludge is particularly important in the process of transportation of sludge. However, the existing turnover device of the double girder gantry crane sludge box is generally the bottom of the sludge box to dump soil, which needs manual cooperation. This method not only increases the construction personnel, but also increases the construction cost. The safety of the construction personnel also has great potential hazards. Another large and small hook is used to realize the turnover and unloading of soil at the top of the slag box. The slag process is complicated and the continuous working efficiency is low. Therefore, we need to put forward a new design scheme to solve the above problems, in which the slag tank can not automatically turn over for unloading and loading.
The invention discloses a load-turning device of slag box of double girder gantry crane, belonging to the field of cranes; Including two sets of support brackets, two sets of support brackets are arranged at parallel intervals to form a bucket chamber, and between the two sets of support brackets are fixed by a longitudinal beam, sliding blocks are movably set on the longitudinal beam, connecting columns are set below the sliding blocks, and overturning components for overturning slag are set below the connecting columns, and connecting columns and overturning components are fixed by a buckle plate, and by setting the overturning components and crank rocker components, To realize the self-turnover function of the slag tank of the crane, driven by the motor, the bucket carries out the slag removal work and limits the limit cylinder through the limit movable rod, so as to prevent the bucket from falling down or difficult to carry out the follow-up work and carry out the work procedure, and complete the automatic transportation and overturning of the slag.Rotation improves work efficiency, guarantees safety of construction personnel and simplifies operation of slag discharging process.
