Lifting gear

Abstract

The invention discloses a lifting transmission device. The lifting transmission device comprises a lifting mechanism for driving a lifting frame; the lifting mechanism comprises a lifting power transmission box, transmission distribution boxes, a transmission shaft and chain wheel systems, wherein the transmission distribution boxes are arranged at the left side and the right side of the lifting power transmission box respectively, the lifting power transmission box is connected with the transmission distribution boxes by transverse connecting shafts respectively, longitudinal transmission shafts are arranged at the front side and the rear side of each transmission distribution box, the inner end of the longitudinal transmission shaft is connected with the transmission distribution box, the outer ends of the longitudinal transmission shafts correspond to the four corners of the lifting frame and are connected with the corresponding corners of the lifting frame by the chain wheel systems correspondingly, a transmission shaft chain wheel of the chain wheel system is arranged at the outer end of the longitudinal transmission shaft, a lifting frame chain wheel is arranged on the lifting frame, a counterweight chain wheel is arranged on a counterweight, and a chain is sequentially connected with the counterweight chain wheel, the transmission shaft chain wheel and the lifting frame chain wheel. The lifting transmission device has lifting synchronization and accuracy in leveling and is energy-saving and safe, so that the lifting platform cannot deflect or swing during lifting, can be operated stably and has reliable safety performance.

Description

[0001] (1) Technical field: [0002] The invention relates to a transmission mechanism, in particular to a lifting transmission device capable of achieving synchronous lifting, accurate leveling and energy saving. [0003] (two) background technology: [0004] At present, mechanical vertical lifting devices, such as the current vertical lifting and traversing type three-dimensional parking garage, the lifting mechanism is driven by a wire rope hoist, and the front and rear pulleys are assembled on the lifting carrier. On the upper fulcrum, the lifting operation is achieved by winding the rope forward and backward by the hoist, and a set of the same pulley block device is installed on the left and right sides. When the lifting height is higher, the diameter of the reel is larger, which not only increases the volume of the equipment but also increases the manufacturing cost.

Problems solved by technology

[0004] At present, mechanical vertical lifting devices, such as the current vertical lifting and traversing type three-dimensional parking garage, the lifting mechanism is driven by a wire rope hoist, and the front and rear pulleys are assembled on the lifting carrier. On the upper fulcrum, the lifting operation is achieved by winding the rope forward and backward by the hoist, and a set of the same pulley block device is installed on the left and right sides. When the lifting height is higher, the diameter of the reel is larger, which not only increases the volume of the equipment but also increases the manufacturing cost. In actual operation, the carrier is used Because it is difficult to ensure that the loaded objects are located at the center balance point of the carrier, the front, rear, left, and right pulleys are unbalanced in force, resulting in natural deviations in the level of the carrier. fall accident
