Problems solved by technology

[0002] The design scheme of the similar hand winch basically satisfies the lifting and labor-saving effect during operation, but there are still some problems in the reverse operation. When the reverse operation is performed, the safety pin must be pulled up and completely separated from the safety wheel to perform the rope release operation. At this time, because there is no protective effect of the safety ratchet, in actual use, the reverse operation basically depends on increasing manpower to ensure the operation of the rope, which is less safe, and the efficiency of the rope is very low, which seriously affects the work efficiency of maintenance.

Abstract

The invention discloses a hand operated grinding mill comprising a main body of the hand operated grinding mill and a rocker arm matched with the main body. The main body of the hand operated grinding mill comprises a grinding mill frame; two ends of the grinding mill frame are provided with a pinion shaft and an intermediate gear shaft in parallel; a core grinding shaft is arranged on the grinding mill frame above the intermediate gear shaft; a gearwheel and a core grinding are arranged by taking the core grinding shaft as a central shaft, a second pinion and an intermediate gear are arranged at two ends of the intermediate gear shaft by taking the intermediate gear shaft as a central shaft, a first pinion is arranged by taking the pinion shaft taken as a central shaft, the gearwheel is engaged with the second pinion, and the intermediate gear is engaged with the first pinion; and the main body of the hand operated grinding mill is also provided with a multi-connecting-rod mechanism which is used for providing reverse resistance when the grinding mill reels off. A simple connecting-rod-operated separated friction plate is used to lock a friction wheel to provide reverse resistance when the grinding mill reels off, thereby achieving the labor-saving effect of reducing labor input.

Description

technical field [0001] The invention relates to a hand winch mill. Background technique [0002] The design scheme of the similar hand winch basically satisfies the lifting and labor-saving effect during operation, but there are still some problems in the reverse operation. When the reverse operation is performed, the safety pin must be pulled up and completely separated from the safety wheel to perform the rope release operation. At this time, because there is no protective effect of the safety ratchet, the operation of releasing the rope is basically guaranteed by increasing manpower during reverse operation in actual use. The safety is poor, and the efficiency of releasing the rope is very low, which seriously affects the work efficiency of maintenance. Contents of the invention [0003] The purpose of the present invention is to overcome the technical problems existing in the prior art, and propose a reverse labor-saving function requirement for the labor-saving hand w...
