Semi-physical training system for mounting and debugging of electrical control circuits of portal cranes and bridge cranes

Abstract

The invention provides a semi-physical training system for mounting and debugging of electrical control circuits of portal cranes and bridge cranes. The system is composed of a crane operation device,a crane electrical control cabinet (comprising an electrical control system of the crane), a substitutional motor and substitutional motor rotary encoder module, a virtual scene signal feedback assembly, a data exchange assembly, an analog computer assembly, and a display and sound assembly. The computer graphic processing technology is adopted, the mechanical structure is subjected to computer virtualization, and the floor area is small. The semi-physical form is adopted, the electrical control system of the crane adopts the real device, the practical-operation-like training can be carried out aiming at the relevant skills of mounting, debugging and repairing and maintenance of the electrical control systems of the portal hoisting devices and bridge hoisting devices, both the skill training effect and resource investment are considered, and the truth degree of skill training is relatively high.

Description

technical field [0001] The invention mainly relates to the technical field of teaching equipment, in particular to a semi-physical training system for the installation and adjustment of electrical control circuits of gantry bridge cranes. Background technique [0002] As my country has become a major manufacturing country in the world, the amount of goods transported has increased rapidly. Portal bridge cranes have been widely used in ports, freight yards, workshops and other occasions that require heavy cargo lifting. The equipment quantity of portal bridge cranes The rapid increase, the degree of automation is also constantly improving, the installation, commissioning and maintenance of the electrical control system of the gantry bridge crane equipment is a very important part of it, which puts forward higher requirements for the relevant personnel training. Require. [0003] At present, many colleges, technical secondary schools, technical training departments and electric...

AI Technical Summary

Problems solved by technology

[0003] At present, many colleges, technical secondary schools, technical training departments and electrician certification have set up practical courses related to the installation, commissioning and maintenance of electrical control circuits of lifting equipment. It takes up a lot of space and is expensive. Generally, only the electric control cabinet is used as the training object for the installation, commissioning and maintenance skills training of the electrical control circuit of the lifting equipment. This is feasible for personnel with relevant practical experience. However, in the actual training process, there are many beginners who do not understand its structure and working principle, and have not even seen the work of a real portal bridge crane. For such beginners, if the training object is just an electronic control Cabinet, the trainees cannot establish the connection between the mechanical mechanism and the electrical part, and they cannot understand the cooperation of each part and the overall working principle and process. The training effect will be greatly reduced, and even cause the separation of training and practice, and the training quality is not high.

[0004] Due to the wide variety of gantry or bridge cranes in practical applications, different functions and huge size and high price, the cost of establishing a practical training facility for the installation, commissioning and maintenance of gantry bridge crane electrical control circuits based on real equipment is very high And it covers a huge area, which will inevitably lead to the lack of training facilities and the lack of sufficient training of students' practical skills. Therefore, the supporting practice of the installation, commissioning and maintenance of the electrical control system of portal bridge crane equipment The research and development of practical training equipment is particularly important. In the process of skill training practice, there is an urgent need for a device that can take into account the effect of skill training and resource input to change the current situation.
