Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically relating to a training and examination crane. Background Technology

[0002] A crane, also known as a tower crane, is a rotating crane with its boom mounted on the upper part of a tall tower. It has a large working space and is mainly used for the vertical and horizontal transportation of materials and the installation of building components in building construction. It consists of three parts: metal structure, working device, and electrical system. The metal structure includes the tower, boom, and base, etc. The working device has four parts: hoisting, luffing, slewing, and traveling. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signal and lighting devices, etc.

[0003] During crane training, instructors operate the equipment from the operator's cab. Because the operator's cab is small, trainees need to stand on an external platform to watch the instructors operate the equipment. However, only trainees on the platform who are closer to the operator's cab can see the instructors' operation, which means that some trainees cannot see the equipment. If trainees move around to change positions, there may be pushing and shoving, which poses a safety hazard.

[0004] Secondly, because there are many students but only one instructor, some students do not learn effectively while watching, resulting in a poor learning outcome.

[0005] To address this, we propose a training and examination crane that enables multiple people to learn simultaneously. The real-time video transmission provides an intuitive display of operational details, allowing trainees to more clearly understand and master the key operational points. Furthermore, real-time observation of trainees' operations allows for a more accurate and comprehensive assessment and scoring of their operational skills. Utility Model Content

[0006] The purpose of this invention is to provide a crane for training and examination. This device enables multiple people to learn simultaneously, and the real-time video transmission intuitively displays the operational details, allowing trainees to more clearly understand and master the key points of operation. Furthermore, real-time observation of trainees' operations allows for more accurate and comprehensive evaluation and scoring of their operational skills.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A training and examination crane includes a small crane body, the small crane body including a vertical support, a fixed plate at the top of the vertical support, a railing fixedly mounted on the fixed plate, a plurality of seat plates mounted on the railing, a control room rotatably mounted at the center of the fixed plate, a plurality of display screens corresponding to the seat plates mounted outside the control room, an operation transmission component electrically connected to the display screens mounted on the control room, and a lifting boom mounted on the top of the control room.

[0009] Furthermore, the operation transmission component includes a video recorder body disposed inside the control room and a distributor disposed on the control room. The video recorder body and the distributor are connected via a first wire, and the distributor is connected to the four displays via four second wires respectively.

[0010] Furthermore, it also includes a magnetic sealing cap.

[0011] Furthermore, a comfort layer is provided on the seat plate.

[0012] Furthermore, a seat belt is provided on the seat plate.

[0013] Furthermore, a fixing seat is provided at the bottom of the vertical support.

[0014] The technical effects achieved by this utility model are as follows:

[0015] During the training phase, trainees first climb onto a fixed platform; the railing effectively prevents them from standing for extended periods, significantly enhancing safety. Trainees sit on the platform to avoid fatigue from prolonged standing, ensuring a good learning state. The instructor then enters the control room to demonstrate and teach the operation of the mini crane. Throughout this process, the operation transmission component captures every step and image of the instructor's operation in real time, transmitting this information to a display screen. Trainees can then watch the instructor's actions in real time for in-depth learning. This design allows multiple trainees to learn simultaneously, and the real-time image transmission significantly improves learning effectiveness. During the exam, the roles of trainee and instructor are reversed. Trainees operate the mini crane, and their operation is displayed in real time via the operation transmission component. Instructors can view the trainees' operation information on the screen and score accordingly. This device enables multiple people to learn simultaneously, and the real-time image transmission intuitively displays operational details, allowing trainees to more clearly understand and master the key points of operation. Furthermore, real-time observation of trainees' operations allows for a more accurate and comprehensive assessment and scoring of their operational skills. Attached Figure Description

[0037] Furthermore, an explanation speaker is installed on control room 6. The explanation speaker can be used to explain the actions, which can improve the learning effect. This is existing technology and will not be elaborated on here.

[0038] The working principle of this practical system is as follows: During the training phase, trainees first climb onto the fixed platform 3, where the railing 4 effectively blocks movement, significantly improving safety. Trainees sit on the seat 5, avoiding fatigue from prolonged standing and ensuring a good learning state. The instructor then enters the control room 6 to demonstrate and teach the operation of the mini crane body 1. During this process, the operation transmission component captures every step and image of the instructor's operation in real time and transmits this information to the display screen 7, allowing trainees to watch the instructor's actions in real time for in-depth learning. This design allows multiple trainees to learn simultaneously, and the real-time image transmission significantly improves learning effectiveness. During the exam, the roles of trainee and instructor are reversed. The trainee operates the mini crane body 1, and the operation image is transmitted in real time to the display screen 7 for display. The instructor can view the trainee's operation information on the display screen 7 and score accordingly. This device allows multiple people to learn simultaneously, and the real-time image transmission intuitively displays the operational details, enabling trainees to more clearly understand and master the key points of operation. Furthermore, real-time observation of trainee operations allows for more accurate and comprehensive evaluation and scoring of trainees' operational skills.
