Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1-3, the hanging type box turnover device provided by the invention comprises a clamping device, a box turnover main frame 2 and a base 5;
two groups of clamping devices are arranged side by side along the transverse direction, and each clamping device comprises a clamping oil cylinder 1 and a clamping hanging frame 11; the clamping cylinder 1 is arranged on the main box turnover frame 2, the output end of the clamping cylinder 1 is in driving connection with the clamping hanger 11, and the output end of the clamping cylinder 1 drives the clamping hanger 11 to move along the direction towards the main box turnover frame 2 so as to clamp the sand box between the clamping hanger 11 and the main box turnover frame 2, or move along the direction away from the main box turnover frame 2 so as to release the sand box clamped between the clamping hanger 11 and the main box turnover frame 2; the main box turnover frame 2 is rotatably arranged on the base 5; a box turnover oil cylinder 4 for driving the box turnover main frame 2 to rotate is arranged on the base 5; the two box turning oil cylinders 4 are arranged side by side along the longitudinal direction, the output end of the box turning oil cylinder 4 is rotationally connected with the box turning main frame 2, and the other end of the box turning oil cylinder is rotationally connected with the base 5.
