Abstract

The invention discloses a hand-operated elevator, and belongs to the technical field of transportation. The hand-operated elevator comprises a rack body, a guide rail groove, a hanging part, a fixed pulley, a haulage rope and a rope coiling rack. The guide rail groove is fixed in the middle of the rack body, and the concave face of the guide rail groove faces upwards. The guide rail groove extendsforwards to excess the bottom of the rack body, and the extending end of the guide rail groove is slightly higher. The fixed pulley is arranged on the upper portion of the rack body. The hanging partcomprises a movable pulley, a bent part and a hook, and the bent part is connected with the two ends of a central spindle of the movable pulley to form an opening. The guide rail groove can penetratethrough the opening, and the movable pulley is clamped into the guide rail groove and moves towards the middle of the rack body. The haulage rope is drawn out from the extending end of the guide railgroove and is wound into a groove of the movable pulley and wound against the fixed pulley; and at last the haulage rope is coiled onto the rope coiling rack. The hand-operated elevator is safe and stable in operation, and materials can be unloaded safely and reliably.

Description

【Technical field】 [0001] The invention relates to the technical field of transportation, in particular to a hand hoist. 【Background technique】 [0002] For building construction or decoration, it is necessary to lift materials to the roof platform. Various types of lifting machinery are commonly used to lift materials to the roof platform. At present, hoisting machinery lifts the material to a high place, and people stand on the roof platform and pull back hard to unload the material. There are potential safety hazards in such unloading mode, and the operation is extremely unsafe. 【Content of invention】 [0003] The invention provides a hand-operated hoist, which is used for hoisting materials on a platform at a high place in a building. [0004] A hand-operated hoist, including a frame body, a guide rail groove, a hanging part, a fixed pulley, a traction rope and a rope coil frame; the lower part of the frame body is a base for supporting the lifting device; the middle...
