Intelligent remote control lorry-mounted crane

Abstract

Provided is an intelligent remote control lorry-mounted crane. The lorry-mounted crane comprises a stand column assembly, a suspension arm assembly, a hydraulic oil tank assembly, a steel wire rope, a back landing leg assembly, a lifting hook assembly, a rack assembly and an oil pump. The invention further comprises a wireless remote control emission control system and a wireless remote control reception control system. In the wireless remote control emission control system, the inputs of an emission controller and an emission control module are respectively connected with proportion rocking bars, a rotary knob and switches, and the outputs of the emission controller and the emission control module are connected with a wireless signal emission module. In the wireless remote control reception control system, a wireless signal reception module outputs signals and instructions, and is connected with a reception controller and a reception control module, and the outputs of the reception controller and the reception control module are respectively connected with a winch motor, a telescopic cylinder, a derricking cylinder, a rotary motor and an accelerator motor through an intermediate relay, an accelerator executor and an electro-hydraulic proportional valve. The intelligent remote control lorry-mounted crane is advantaged by complete remote control functions, safety and high efficiency, and greatly raises the qualities and the technical performance of a lorry-mounted crane.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an intelligent remote control truck-mounted crane, which is widely used in transportation, civil construction, electric power and telecommunications, field operations, stone materials, gardens, oil fields, military, port cargo loading and unloading, emergency rescue, long-distance Transshipment, 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 product...

AI Technical Summary

Problems solved by technology

Due to the fact that domestic enterprises have little investment in the research and development of truck-mounted cranes, there is a certain gap in the advanced technology of hydraulic systems and control systems.

[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
