The invention discloses a construction site crane, and relates to the technical field of cranes, the construction site crane comprises a supporting base, the supporting base is connected with a connecting rod through a connecting block, the connecting rod is provided with a moving part, and a first transmission gear and a second transmission gear arranged on the moving part move on a connecting tooth groove formed in the outer wall of the connecting rod; a protection plate connected to the second transmission gear rotates to wrap and protect the hook connected to the connecting rod; according to the crane for the construction site, the moving part moves up and down to drive the protection plate to rotate, the protection plate wraps the hook during falling, the hook is prevented from shaking in the falling process, the personal safety coefficient of workers is greatly improved, the hook is connected with an elastic limiting ring, the limiting ring is connected with a clamping block in an inserted mode, and therefore the safety coefficient of the workers is greatly improved. And a limiting block is fixed, so that a certain economic loss caused by the fact that a rope on a hook slips down due to the fact that a hung object shakes can be avoided, and the practicability of the device is greatly improved.
本发明公开了一种建筑工地起重机,涉及起重机技术领域,包括支撑底座,支撑底座通过连接块连接有连接杆,连接杆上设置有移动部件,移动部件上设置的第一传动齿轮和第二传动齿轮在连接杆外壁开设的连接齿槽上移动,且第二传动齿轮上连接的防护板转动对连接杆上连接的挂钩进行包裹防护;该建筑工地起重机,通过移动部件上下移动带动防护板转动,防护板在下落时对挂钩进行包裹,避免挂钩在下落的过程中发生晃动,大大提高了工作人员的人身安全系数,以及在挂钩上连接可松紧的限位圈,通过限位圈与卡接块插接,对限位块进行固定,能够避免悬挂物品发生摇晃,导致挂钩上的绳索滑落掉下,造成一定的经济损失,大大提高了该装置的实用性。
