The invention discloses a quick lifting machine of a shear type lifting platform. The quick lifting machine comprises a rack. A shear type mechanism and a lifting oil cylinder are arranged on the rack, the top end of the shear type mechanism is a platform panel, the end of an output rod of the lifting oil cylinder is provided with a movable pulley, the movable pulley is winded with a chain, one end of the chain is fixedly connected with a shear rod of the shear type mechanism, and the other end of the chain is fixedly connected with a cylinder body of the lifting oil cylinder. According to the quick lifting machine for the shear type lifting platform, through the match of the movable pulley with the lifting oil cylinder and the chain, the lifting speed of the platform panel is increased greatly, enlarging is achieved on extending speed of the lifting oil cylinder, the work efficiency of the shear type lifting platform is increased, the reduction of the use-cost of users is facilitated, and the lifting machine is suitable for replacing an existing shear type lifting machine.
