Power and free overhead conveyer

Abstract

The invention discloses a power and free overhead conveyer which comprises a quick chain rack, an overhead conveyer, a low-speed chain rack and a control system, wherein a quick chain traction track is arranged in the quick chain rack, a chain wheel device is arranged below the quick chain traction track, a quick chain bearing rack is arranged below the chain wheel device, a driving wheel is arranged on the quick chain traction track, a drag rod is arranged on the driving wheel, the lower end of the drag rod is connected with a guide block arranged on the chain wheel device, two ends of the chain wheel device are provided with chain wheel driving systems, and a load feedback tightening system is arranged in each chain wheel driving system. The power and free overhead conveyer has the advantages that a lifting claw structure is adopted for a travelling bogie of the conveyer, in a power and free state, the kinetic energy of the trolley is converted into potential energy, and when the trolley is started, potential energy is converted into kinetic energy, thus saving energy for operation of the trolley.

Description

technical field [0001] The invention relates to a hanging conveyor, more specifically, to a product-and-free hanging conveyor. Background technique [0002] Suspension conveyor is a continuous transportation equipment with a space-enclosed line. It can realize downhill and turning in space. It has the advantages of flexible layout and small footprint. Therefore, it is widely used in machinery, automobiles, electronics, It is widely used in mass flow production operations in industries such as household appliances, light industry, food and chemical industry. [0003] At present, there are mainly the following problems in the use of ordinary suspension conveyors: [0004] Ordinary suspension conveyors use the speed signal of the chain, which cannot truly reflect the real speed of the chain, resulting in the asynchronous processing of the workpiece being conveyed and the workpiece, especially in an environment with a high degree of automation in the production line and a fast ...

Problems solved by technology

[0009] Chinese patent application number CN200720040917.X, the name of the invention is: a hoisting claw lifting device for accumulative suspension conveyor spreader; the application provides a hoisting claw 1 and a forced plate 5 used together, the trolley passes in front of the spreader , once the lowering of the front shovel 6 of the spreader is blocked, failing to drive the lifting claw 1 of the spreader to rise synchronously with the catenary pusher 2, it may cause the decoupling between the lifting claw 1 of the spreader and the catenary pusher 2, After adding the forcing plate 5, the lifting claws will basically rise synchronously with the catenary push head 2 under the action of the forcing plate 5 to ensure the absolute reliability of chain changing

The lifting claw 1 of this application also cannot achieve the purpose of saving energy for the operation of the trolley.
