Intelligent lorry crane with intelligent operation control system

Abstract

An intelligent lorry crane with an intelligent operation control system comprises a column assembly, a boom assembly, a hydraulic oil tank assembly, a steel wire rope, a rear supporting leg assembly, a lifting hook assembly, a frame assembly, and an oil pump; according to the invention, a program controller is mounted on an automotive chassis; a length sensor, an angle sensor, a limit switch, and a second balance valve are mounted on the boom assembly; an upper cavity pressure sensor, a lower cavity pressure sensor, and a first balance valve are mounted on the column assembly; a multi-way valve, a normal open solenoid valve, a tilt sensor, an oil temperature sensor, a central rotation slip ring, and an alarm are mounted on the frame assembly; the program controller is connected with a Canbus bus; the Canbus bus is respectively connected with the length sensor, the angle sensor, the upper cavity pressure sensor, the lower cavity pressure sensor, and the limit switch through the central rotation slip ring; the oil temperature sensor, the tilt sensor, the normal open solenoid valve, and the alarm below the frame are respectively connected by corresponding branch lines in the Canbus bus. The invention adopts advanced electronic technology and information processing technology, has multiple display functions, can perform alarming and protection of system faults, and greatly improve the technical performance and quality of the lorry crane.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an intelligent truck-mounted crane, which can be widely used in transportation, civil engineering, electric power and telecommunications, field operations, stone, gardens, oil fields, military, port cargo loading and unloading, emergency rescue, remote Distance transfer, as well as bridge maintenance, high-altitude wire detection, fire safety engineering and other operating fields. Background technique [0002] The current status and shortcomings of truck-mounted cranes in my country are as follows: [0003] 1. There are few varieties and low yield. my country's existing truck-mounted cranes are in the primary stage of development. There are few varieties, and there are many repetitions of small and medium tonnages. So far, a complete series of large, medium and small has not been formed. The annual output is only equivalent to the production capacity of a foreign...

AI Technical Summary

Problems solved by technology

At present, domestic enterprises invest very little in the research and development of truck-mounted cranes, and there is a certain gap between the level of hydraulic system and control system compared with advanced technology.

[0005] 3. Incomplete safety devices and inconvenient operation

The existing truck-mounted cranes in our country are only equipped with general safety devices such as "lifting height", "limit", "balance valve" and "overflow valve", and all of them are manually operated. The safety devices are not complete and the operation is inconvenient.

[0006] 4. Single function

[0007] 5. The appearance is not beautiful
