The invention discloses a jacking system, an H-shaped steel standard knot tower crane and a jacking method of the H-shaped steel standard knot tower crane, and solves the technical problem of low automation degree of a traditional H-shaped steel standard knot tower crane jacking system. The jacking system comprises a first braking mechanism, a second braking mechanism and a driving mechanism, the first braking mechanism is movably connected with a sleeve frame body fixed jacking beam, the second braking mechanism is movably connected with a movable jacking cross beam, the driving mechanism is connected with the sleeve frame body fixed jacking beam and the movable jacking cross beam, the driving mechanism drives the sleeve frame body fixed jacking beam and the movable jacking cross beam to ascend or descend to drive the first braking mechanism and the second braking mechanism to ascend or descend, and the first braking mechanism and the second braking mechanism are fixed to or separated from steps on an H-shaped steel main chord member under the action of self weight and/or pulling force. The jacking system is in a semi-automatic braking mode, and compared with a braking mode of the traditional H-shaped steel standard knot tower crane jacking system, the jacking system has the advantage that the automation degree of the jacking system is improved.

    本发明公开了一种顶升系统、H型钢标准节塔式起重机及其顶升方法,解决了传统H型钢标准节塔式起重机顶升系统的自动化程度低的技术问题。该顶升系统包括第一制动机构、第二制动机构和驱动机构,第一制动机构与套架体固定顶升梁活动连接,第二制动机构与活动顶升横梁活动连接,驱动机构与套架体固定顶升梁和活动顶升横梁连接,驱动机构通过驱动套架体固定顶升梁和活动顶升横梁上升或下降而驱动第一制动机构和第二制动机构上升或下降,并使第一制动机构和第二制动机构通过自重和/或拉力的作用与H型钢主弦杆上的踏步固定或分离。该顶升系统为半自动的制动方式,相比于传统H型钢标准节塔式起重机顶升系统的制动方式,其自动化程度提升。
