The invention relates to the technical field of cranes, and discloses a windproof tower crane which comprises a tower body, a jacking mechanism is connected to the top of the peripheral side of the tower body in a sleeving mode, the windproof tower crane comprises a windproof mechanism, the windproof mechanism is composed of a fixing frame and four inhaul cable mechanisms, and the fixing frame is fixedly connected to the bottom of the side wall of the jacking mechanism; the inhaul cable mechanism is used for tensioning the periphery of the fixing frame to improve the stability of the tower body. The inhaul cable mechanism is composed of a hoisting mechanism, a switch type guide pulley, a one-way pulley and a balancing weight, the hoisting mechanism is installed on the ground on the peripheral side of the tower body and wound with a steel rope, the switch type guide pulley is arranged at the bottom end of the side wall of the tower body, and the one-way pulley is installed at the top of the fixing frame. The steel rope bypasses the switch type guide pulley, is vertically upward, bypasses the one-way pulley, is vertically downward and is connected with the balancing weight; according to the tower crane, the windproof mechanism is additionally arranged on the basis of an original tower crane, inclined downward traction force can be formed on the periphery of the tower body through the four inhaul cable mechanisms of the windproof mechanism, the overall stability of the tower crane is improved, and the toppling condition caused by strong wind is avoided.
本发明涉及起重机技术领域,且公开了一种防风塔式起重机,包括塔体,塔体周侧顶部套接有顶升机构,包括有防风机构,防风机构由固定框及四个拉索机构,固定框在顶升机构侧壁底部固定连接,拉索机构用于将固定框四周拉紧提升塔体稳固性;拉索机构由卷扬机构、开关式导向滑轮、单向滑轮、配重块构成,卷扬机构安装于塔体周侧地面并卷绕有钢绳,开关式导向滑轮设置于塔体侧壁底端,单向滑轮安装于固定框顶部,钢绳绕过开关式导向滑轮垂直向上并绕过单向滑轮垂直向下与配重块连接;本发明在原有塔式起重机基础上增设防风机构,通过其结构的四个拉索机构,可对塔体四周形成斜下的牵引力,提升塔式起重机的整体稳定性,避免因强风发生倾倒状况。
