Vertical bidirectional conveying device based on chain transmission

Abstract

The invention relates to the technical field of mechanical transmission, in particular to a vertical bidirectional conveying device based on chain transmission. The vertical bidirectional conveying device comprises chain wheels, transmission chains, guide rails, carriers and a chain wheel support. The chain wheels are driven by input torque to rotate around a shaft in a directional mode to drive the transmission chains to move in a directional mode. One transmission chain moves upwards, and the other transmission chain moves downwards. Materials needing to be conveyed upwards are loaded on the transmission chain which moves upwards after being loaded into the carriers, are driven by the corresponding transmission chain to convey upwards and are unloaded at preset positions. Meanwhile, materials needing to be conveyed downwards can be carried by the other transmission chain and conveyed downwards. Intermittent motion is adopted in the whole system; in other words, the materials only move by one clamping height during each time of ascending or descending and stay a certain period of time so that loading or unloading can be completed. A working part used in the conveying device is a transmission chain part which is internally and externally covered with the guide rails, and therefore it can be guaranteed that the carriers moving at the part always keep moving in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a chain transmission vertical two-way transmission device. Background technique [0002] With the advancement of science and technology and the development of human society, the activity space required by human beings is getting larger and larger, and people have to occupy forests, grasslands, and wetlands to meet people's growing land needs, which in turn has caused serious damage. Ecological destruction and environmental pollution; however, the earth's area is limited after all, forcing people to move from flat to three-dimensional, with taller and taller buildings, deeper and deeper basements, and people gradually living on different levels; therefore, How to efficiently complete the material circulation between different levels will become a key technology to ensure the sustainable and healthy development of human society. A chain drive vertical two-way transm...

Problems solved by technology

[0003] Due to the limitations of its own structure, traditional vertical conveying devices (such as elevators, conveyor belts, vertical conveyors, etc.) are difficult to meet the requirements of large load and large volume. It will become an urgent requirement and an inevitable trend; on the other hand, the high-speed operation of the economy and society also requires the high-speed logistics; at the same time, with the increasingly prominent energy problems, it is also required to meet the large volume and high speed. Reduce energy consumption and improve energy utilization

[0004] Elevator (application number: 201210310573.5), limited by its structure, can only accommodate one elevator in an elevator shaft; the elevator has a limited load, and can only transport a small amount of materials at a time; when transporting a large amount of materials, the elevator needs to move up and down continuously, When the transportation distance is long, it needs to wait for a long time due to the limitation of the running speed of the elevator; on the other hand, every time the goods are transported upwards, the elevator needs to overcome the gravity to do work, and at the same time, in order to increase the running speed of the elevator, the kinetic energy of the elevator must be increased , in the case of excluding other energy consumption, this will also consume a lot of energy; although the elevator can now convert part of the mechanical energy into electrical energy by collecting kinetic energy during deceleration to reduce energy loss, there is still energy loss during the energy conversion process. It is said that the energy utilization rate of elevators is still low. In summary, it is difficult for elevators to meet people's requirements for large-volume, high-speed, and low-energy vertical transportation technologies.
