Upper loading frame of port unmanned container transport vehicle

Abstract

The invention discloses an upper loading frame of a port unmanned container transport vehicle. The upper loading frame comprises an upper loading frame longitudinal beam and an upper loading frame cross beam vertically fixed to the upper loading frame longitudinal beam; the upper loading frame longitudinal beam is provided with an assembling and fixing structure which is detachably fixed with a main frame; and the upper loading frame cross beam is provided with a guide structure used for guiding a container to fall into the middle of the upper loading frame cross beam, and the upper loading frame longitudinal beam is fixedly provided with a limiting structure used for limiting the front-back position of the container. The upper loading frame is simple in structure and good in bearing capacity, and has guiding and positioning functions on loading and unloading of the container. The upper loading frame is simply connected to the main frame, the reliability is high, and the requirements of the design and manufacturing process are simple. Even if the container falls and impacts the upper loading frame all the year round, and the bearing contact surface of the upper loading frame is abraded and rusted, the upper loading frame can be directly hoisted and replaced without replacing the whole chassis, so that the maintenance cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobile chassis, in particular to an upper loading frame of an unmanned container transport vehicle at a port. Background technique [0002] At present, most driverless smart trucks on the market are rebuilt from pure electric trucks with cabs equipped with intelligent systems or AGVs equipped with intelligent systems. [0003] The application number is CN202110351747.1, and the patent name is "A Transport and Self-unloading Dual-purpose Skeleton Container Semi-trailer Embedded in the Subframe", which discloses a dual-purpose transport and self-unloading semi-trailer embedded in the subframe. A frame container semi-trailer, which includes a main frame container semi-trailer, an embedded subframe, a turning mechanism and a hydraulic lifting system, wherein: the hydraulic lifting system is arranged at the head end of the main frame container semi-trailer, and the embedded The head end of the sub-frame i...

AI Technical Summary

Problems solved by technology

The layout of pure electric unmanned trucks has always needed to solve the three problems of bodywork adaptation, compact structure and related components. All the above-mentioned solutions have common or respective limitations, as follows: Unmanned collection trucks have certain limitations due to the layout of trucks. The front space occupies too much space and the driver's cab is redundant, resulting in a long vehicle size.

The power battery, suspension, and motor are exposed, and they are visually fragmented and not integrated

However, the limitations of unmanned trucks based on AGV transformation are as follows: the upper body and sub-frame are integrally welded and formed, which cannot cope with scenarios that require different upper bodies, and the adaptability to operating scenarios is poor; if the upper body is damaged, the entire frame needs to be replaced, and the maintenance workload huge
