Manual screw hoist capable of automatically descending
The invention provides a manual screw hoist capable of automatically descending, belongs to the technical field of water conservancy projects, and aims to solve the technical problems that an existing manual screw hoist cannot automatically close a gate, the labor intensity of operators is high, and the gate closing speed is low. Comprising a shell, a worm gear and a worm are mounted in the shell, a mounting cavity is formed in the middle of the worm gear, two meshing plates and two clamping plates are arranged in the mounting cavity, a separating mechanism and a clamping mechanism are arranged on the worm gear, a screw is arranged between the two meshing plates, and meshing teeth meshed with the screw are arranged on the sides, close to the screw, of the meshing plates; according to the manual screw type hoist capable of automatically descending, before the meshing teeth are separated from the screw, the screw is fixed firstly, then the gravity of the screw and the gravity of a gate do not act on the edges of the meshing teeth, automatic and rapid gate closing can be achieved, and the service life of the meshing teeth is prolonged.
本发明提供了一种可自动下降的手动螺杆式启闭机，属于水利工程技术领域，用于解决现有的手动螺杆式启闭机不能自动关闸，操作人员劳动强度大，关闸速度慢的技术问题。包括外壳，外壳内部安装有蜗轮和蜗杆，蜗轮中间开设有安装腔，安装腔中设置有两个啮合板和两个夹紧板，蜗轮上设有分离机构以及夹紧机构，两个啮合板之间设置有螺杆，啮合板靠近螺杆的一侧设置有与螺杆啮合的啮合齿；本可自动下降的手动螺杆式启闭机将啮合齿与螺杆分离之前，先将螺杆进行固定，之后螺杆和闸门的重力不会作用在啮合齿的边沿处，不仅能够实现自动快速关闸而且提高啮合齿的使用寿命。
