Hydraulic suspension heavy load agv

Abstract

The invention relates to an AGV trolley and concretely relates to a hydraulic and suspension type heavy duty AGV. The hydraulic and suspension type heavy duty AGV comprises a driving unit and an AGV body, wherein the AGV body is loaded via the driving unit; the driving unit has a hydraulic cylinder, driving devices and driving wheels; two driving wheels are arranged on two sides of the driving unit and driven to rotate by two different driving devices; the hydraulic cylinder is rotationally arranged in the middle of the driving unit; a rotary center axis of the hydraulic cylinder is perpendicular to an axial center line of the driving wheels; and the AGV body is connected with the hydraulic cylinder. An original spring combination is replaced by the hydraulic cylinder for guarantee of driving force of the driving wheel, so AGV loading capacity can be greatly improved.

Description

technical field [0001] The invention relates to an AGV trolley, in particular to a hydraulically suspended heavy-duty AGV. Background technique [0002] In recent years, heavy industry has developed rapidly, and the demand for heavy industry equipment has grown rapidly. In the production process of heavy industrial equipment, the handling efficiency of heavy-duty parts directly affects the processing progress and production efficiency of the entire equipment. The traditional way of transporting heavy cargo is relatively single. The common ways are driving, rail transportation system, large trailers and cranes, etc., but the above transportation methods have many limitations, such as difficult installation, huge volume, and inability to realize all-round Walking, high labor costs, etc., so heavy industry equipment manufacturers are gradually adopting heavy-duty AGVs with a higher degree of automation and larger loads to solve the problem of heavy-duty parts handling, but tra...

Problems solved by technology

The traditional way of transporting heavy cargo is relatively single. The common ways are driving, rail transportation system, large trailers and cranes, etc., but the above transportation methods have many limitations, such as difficult installation, huge volume, and inability to realize all-round Walking, high labor costs, etc., so heavy industry equipment manufacturers are gradually adopting heavy-duty AGVs with a higher degree of automation and larger loads to solve the problem of heavy-duty parts handling, but traditional AGVs generally use integral drive wheels to Carry out driving and walking, and maintain the pressure of the driving wheel on the ground in the form of a spring group. As the load of the AGV increases, the positive pressure required for the driving wheel also increases. The data obtained after a large number of experiments generally show that the load is 20 When the load is about 1 ton, the traditional spring set can no longer meet the requirements of providing positive pressure due to design and processing problems, and the pressure that the integral drive wheel can carry is also very limited, and it cannot be further expanded.
