Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting and lifting machinery, and particularly relates to a vertical reciprocating automatic conveying and hoisting machine. Background Art

[0002] The reciprocating hoist, also called a hoist or a lift, is just a kind of up-and-down reciprocating conveying equipment in lifting equipment. This kind of hoist has the characteristics of advanced control, reliable performance, high positioning accuracy of the lifting car, etc. In the prior art, the reciprocating hoist often drives the hoisting drum to rotate through a motor, and the hoisting drum hoists the hanging frame by winding and unwinding the steel wire rope, that is, the flexible part, the steel wire rope and the transported goods are driven by a power machine to move up and down to complete the transportation. Multiple sets of movable pulley assemblies are required. A large frictional force will be generated between the steel wire ropes of each group of movable pulley assemblies and between the steel wire rope and the hoisting drum. Therefore, it is necessary to frequently lubricate and maintain the steel wire rope. The steel wire rope will be deformed under the influence of temperature and tension. Therefore, a large error will occur between each section of the steel wire rope. After a long time of reciprocating hoisting work, the lifting force of the hanging basket will be uneven, and in severe cases, the steel wire rope will break. Therefore, in the prior art, it is inconvenient to maintain the steel wire rope when hoisting the hanging basket with the steel wire rope, and the steel wire rope needs to be frequently replaced. Moreover, after the hanging basket lifts the heavy object to a high place in the prior art, it is inconvenient to move the goods out of the hanging basket. Content of the Utility Model

A hanging frame is arranged in the support frame, and a feeding mechanism for conveying materials is arranged at the bottom of the hanging frame, and the feeding mechanism includes a plurality of conveying rollers arranged in parallel, both ends of the conveying rollers are rotatably assembled at the lower end of the hanging frame through a support shaft, and two second transmission sprockets arranged at intervals are fixed on the support shaft at one end of the conveying roller, and a feeding motor is fixed on the hanging frame below the conveying roller, and the feeding motor is synchronously connected with each conveying roller through a transmission chain (not shown in the drawings of the specification), and the feeding motor is started, and the feeding motor drives each conveying roller to rotate synchronously and in the same direction through the transmission chain, so as to facilitate the conveying of the materials on the conveying roller out of the hanging frame. A lifting mechanism for lifting the hanging frame is provided at the top of the uppermost supporting frame. The lifting mechanism includes a lifting motor and a reducer fixed at the top of the supporting frame, and also includes two parallel and spaced first rotating shafts and a second rotating shaft.

Both ends of the first rotating shaft and both ends of the second rotating shaft are fixed with a first transmission sprocket. The power output shaft of the lifting motor is connected to the first rotating shaft through a first chain after being decelerated by the reducer. The second chain, the third chain, the fourth chain and the fifth chain are respectively fixed at the four corners of the top of the hanging frame. A vertically arranged counterweight mechanism is provided on the right side inside the supporting frame. The counterweight mechanism includes a counterweight block. The other ends of the second chain and the third chain bypass the second rotating shaft and the first rotating shaft and are fixed to the top of the counterweight block. The other ends of the fourth chain and the fifth chain bypass the first transmission sprocket on the first rotating shaft and are detachably fixed to the top of the counterweight block. The lifting motor is started, and the lifting motor pulls the hanging frame up and down through the second chain, the third chain, the fourth chain and the fifth chain.

[0004] Preferably, vertically arranged counterweight guide rails are detachably fixed on the support frames on both sides of the counterweight, and a counterweight guide slider matching the counterweight guide rails is fixed on the counterweight.
