The invention discloses a chain block back-pushing jacking device which comprises an outer main frame (1) located at the bottom and provided with an opening in the upper end, an inner jacking frame (2) sleeved with the outer main frame (1) from the opening in the upper end and a lifting chain block fixed to the bottom of the outer main frame (1), and a shell of the lifting chain block is connectedwith the outer main frame (1). The tail end of the chain block is connected with the inner jacking frame (2), the lifting chain block can drive the inner jacking frame (2) to move up and down in theouter main frame (1), and maintenance equipment is placed on the top surface of the inner jacking frame (2). According to the chain block back-pushing jacking device, the problem that rooting, hoisting and overhauling cannot be conducted due to narrow space in the equipment overhauling process is solved, and rapid and accurate positioning, jacking and installing can be achieved.
