Abstract

The invention relates to a safe anti-falling device of a lifting handcart. The safe anti-falling device of the lifting handcart comprises a reduction gear box. The safe anti-falling device of the lifting handcart is characterized in that a reduction mechanism is installed on the inner side of the reduction gear box, and a storing cavity is installed on the outer side of the reduction gear box; and a driving shaft, a ratchet wheel, a pawl, friction plates, a spiral compression device and a safe anti-falling device body are installed in the storing cavity, wherein the pawl is movably installed on the gear box, the ratchet wheel is rotatably installed on the driving shaft, the friction plates are installed on the two sides of the ratchet wheel in the axial direction, one end of the driving shaft is connected with the reduction mechanism, the other end of the driving shaft is connected with the spiral compression device, the safe anti-falling device body is installed between the spiral compression device and the outer side friction plates, and the safe anti-falling device body is fixedly connected with the spiral compression device. By adoption of the structure, the safe anti-falling device can provide overload protection for the lifting handcart or provide safe protection when the inner friction plates loss efficacy.

Description

technical field [0001] The invention relates to a lifting handcart, in particular to a safety anti-drop device for a lifting handcart. Background technique [0002] Traditional lifting handcarts, as disclosed in Chinese invention patent 200720154117.0, because there is no safety anti-drop device, when the load of the lifting handcart is too large, the internal friction plate wears out or the operation is misoperated, heavy objects will often fall rapidly. In severe cases, it will hit the staff and cause work-related accidents. [0003] Therefore, the traditional lifting handcart needs to be further improved, and a safety anti-drop device for lifting handcart proposed in this patent is proposed to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a safety anti-drop device for a lifting handcart, which can provide overload protection for the lifting handcart, or provide safety protection when the function of the ...
