Abstract

The invention provides a power-driven lift platform carrier vehicle for a steel mill, comprising an engine, a carriage, a hydraulic system with an oil cylinder, at least one cab, an engine control unit, a vehicle-mounted terminal system, a PLC control system and related executive mechanisms; and in the process, data is transmitted by respectively using CAN, MIPI and USB protocol to finish the control of a finished vehicle. The invention has the advantages of having higher driving speed, satisfying logistics operation efficiency in the steel mill, being capable of continuous operation in full load working condition, having compact installation structure of the parts and conforming to the requirement of road boundary line.

Description

Technical field [0001] The invention relates to a frame transport vehicle, in particular to a power lift flat frame transport vehicle for steel mills. Background technique [0002] The road transportation of finished products in the steel plant is an important part of the logistics transportation in the factory. The traditional method uses ordinary flatbed transport vehicles. However, due to the low load capacity and long waiting time for loading, its transportation efficiency is low, which increases Logistics operation costs. The frame transportation mode is being adopted by more and more steel mills because it shortens the waiting time for loading and improves the utilization rate of vehicles. The frame transportation mode generally adopts a unified specification frame as the carrier of cargo turnover. This has higher requirements for the frame-carrying flatbed transporter: (1) It has a higher driving speed and meets the efficiency of logistics operations in the factory; (2) I...

AI Technical Summary

Problems solved by technology

Although this kind of frame transport vehicle can realize the logistics transportation function in the factory, due to the limitations of the frame structure, steering mode, system control ability, etc., its transportation effect is poor, and it has the following defects:

[0004] 1. Since the transmission system, electronic control system and the overall structure are characterized by heavy load and low speed, the driving speed is generally lower than 15km / h, and the transportation efficiency is low, which cannot meet the process transportation needs of the continuous operation production line

[0005] 2. In order to meet the volume and weight requirements of the carrying object, limited by the uniaxial load on the road surface, the body size of the large-scale power flatbed transport vehicle is relatively large. For the boundary conditions of road transportation, it is generally an ultra-wide and ultra-long vehicle, so it is not suitable It is used as an internal process transport vehicle in a steel plant; the transport vehicle in the plant is required to meet the requirements of the external dimensions of special road transport vehicles, the width is generally less than 3.2m, the components are compactly arranged and the function integration is high, and the parts are exposed to high temperature and dust. The performance requirements under harsh conditions such as vibration and vibration are relatively high, and its components have a higher technical level than ordinary large-scale flatbed transport vehicles.

Therefore, it is difficult for ordinary large-scale flatbed transport vehicles to meet the needs of operation in the factory.

[0006] 4. Most of the existing power flatbed transport vehicles focus on the realization of functions, that is, the design of load capacity. There is no safety system designed for the vehicle in the steel plant environment, and there are no corresponding measures for the safety hazards such as fires that exist due to continuous heavy-duty operation of the vehicle. In the event of a fire, the entire vehicle will suffer catastrophic damage, and the operator may also suffer serious personal injury

[0007] 5. The existing power flatbed transport vehicles do not have supporting management equipment for the internal process transportation of steel mills. For logistics operations such as vehicle scheduling and transportation route selection, traditional manual methods can only be used, which has become a bottleneck for improving vehicle turnover and transportation efficiency. Increased logistics costs
