The invention relates to the technical field of cranes, and discloses a simple crane which comprises a fixing plate, connecting rods are fixedly mounted at the left end and the right end of the interior of the fixing plate, an air supply mechanism is fixedly mounted in the fixing plate, and an early warning mechanism is fixedly mounted at the lower end of the fixing plate and located on the opposite faces of the connecting rods. According to the simple crane, in the downward movement process of the connecting rod, the rack can be driven to move, so that the rack moves downwards to drag the arc-shaped wheel to rotate, then the radius of an opening in the upper end of the arc-shaped wheel becomes larger and smaller, and the radius of the lower end of the arc-shaped wheel becomes smaller and smaller, so that the number of vibration pieces exposed under gas becomes larger and larger; therefore, the sound of the horn device becomes larger and larger, the effects of notifying constructors in time and preventing the constructors from not hearing the sound are achieved, the trigger mechanism can be started in cooperation with the action of the transverse plate and the guide rod, and the trigger mechanism can conduct remote control and feedback information.

    本发明涉及起重机技术领域,且公开了一种简易式起重机,包括固定板,所述固定板内部的左右两端均固定安装有连接杆,所述固定板的内部固定安装有供气机构,所述固定板的下端且在连接杆的相对面上固定安装有预警机构。该简易式起重机,通过连接杆在向下运动过程中,可以带动齿条运动,从而齿条向下运动,拖动弧形轮发生转动,然后弧形轮上端的开口半径越来越大,下端的半径越来越小,从而暴露在气体下的震动件个数越来越多,所以喇叭装置的声音越来越大,从而实现了及时通知施工人员,避免其听不到声音的效果,而且配合横板和导杆的作用,可以启动触发机构,触发机构可以进行远程控制,反馈信息。
