The invention discloses an oil cylinder lifting type drilling rig power catwalk. The oil cylinder lifting type drilling rig power catwalk comprises a catwalk body. The catwalk body is longitudinally provided with a concaving space, a V-type drill column conveying device is placed in the catwalk space, the upper plane of the V-type drill column conveying device is flush with the upper plane of the catwalk body, a drill column device idler wheel is arranged at the front end of the V-type drill column conveying device, and the front end of the catwalk body makes contact with the lower end of a slope. The rear end of the V-type drill column conveying device is hinged to the rear end of a support, and the front end of the support is hinged to the front end of a moving pulley, the rear end of the moving pulley is hinged to an overturning oil cylinder, the other end of the overturning oil cylinder is hinged to the lower portion of the support, the rear end of the moving pulley is hinged to the front end of a moving oil cylinder, and the rear end of the moving oil cylinder is hinged to a supporting seat at the rear end of the catwalk body. The oil cylinder lifting type drilling rig power catwalk is higher in safety, and the slope does not need to be specifically made; a drill column can be lifted upwards through main power and put down through main power either and especially when the drill column is put down, self-weight is not needed, and dead point positions do not exist.
