Description

Technical Field

[0001] The invention relates to the technical field of equipment maintenance, in particular to a self-adjusting maintenance platform for maintenance of fully mechanized mining and excavation equipment based on a level sensor. Background Art

[0002] With the rapid development of automation technology, traditional equipment maintenance methods are gradually transforming towards intelligence and automation. In the maintenance of various industrial equipment, especially in the maintenance of comprehensive mining and excavation equipment, how to efficiently and accurately adjust the angle of the maintenance platform has become a key factor in improving maintenance efficiency and ensuring the long-term stable operation of the equipment. Comprehensive mining and excavation equipment usually operates in harsh working environments. Therefore, equipment maintenance work often requires frequent adjustment of the angle of the maintenance platform to adapt to different working postures and working conditions.

[0003] At present, some maintenance table adjustment systems use mechanical devices or manual control methods to adjust the angle of the maintenance table. These systems adjust the position of the maintenance table by means of electric push rods, manual wheels or hydraulic devices.

[0004] However, the existing maintenance platform has prominent accuracy problems. Traditional manual control methods often make it difficult to adjust the platform in place every time, which easily causes angle errors and affects maintenance efficiency. There is a lack of real-time monitoring and automatic feedback mechanisms, and the status of the equipment is often not perceived and adjusted in a timely manner. The adjustment process lacks effective data support, and the existing technology is difficult to adapt to different sizes of comprehensive mining and excavation equipment, thereby reducing the use value of the maintenance platform.

[0027] Working principle: First, the horizontal state of the support plate 206 is detected by the sensor. When adjustment is needed, the guide slider 203 can be driven to move in the internal groove of the base 1 by starting the electric push rod 201, so that one end of the telescopic rotating rod 204 rotates along the outside of the guide slider 203, so that the other end of the telescopic rotating rod 204 is raised to adjust the balance; after the adjustment is completed, the connecting rotating rod 302 is driven to rotate the gear 303 by starting the motor 301, and the two racks 304 are driven to move in opposite directions through the mutual meshing of the gear 303 and the rack 304, so that the connecting block 305 moves synchronously, and then the moving plate 306 drives the maintenance table 1 307 and the maintenance table 2 308 to move away from each other, so that the size of the maintenance table surface can be conveniently adjusted, so that it can have a wide range of applications; After the maintenance table is adjusted, the limit block 503 can be pressed to compress the compression spring 504, so that the limit block 503 can be retracted into the groove outside the telescopic rod 502, and the telescopic rod 502 can be moved out of the inner wall of the sleeve 501 by pulling down the telescopic rod 502, so that the limit block 503 re-enters the limit slot 505 under the rebound effect of the compression spring 504, so that the length of the telescopic rod 502 moved out can be conveniently fixed, so that the stability of the maintenance table can be increased after the balance adjustment of the maintenance surface is completed; The horizontal sensor in the sensor module monitors the angle changes of the maintenance platform in real time, including the pitch angle and the roll angle. When the angle of the maintenance platform deviates from the preset standard, the sensor sends the angle data to the control module. The control module uses a programmable logic controller to receive the sensor data, calculate the angle deviation, and output an adjustment instruction based on the calculation result to control the driving source in the execution module. The driving source drives the adjustment device of the maintenance platform according to the control instruction to accurately change the angle of the maintenance platform to restore it to the required working state. The human-computer interaction module provides a user interface through which the operator can monitor the angle of the maintenance platform in real time and manually control the adjustment of the maintenance platform when necessary. The safety protection module uses the emergency stop button to quickly cut off the system power supply in the event of an accident or failure to prevent further misoperation or damage and ensure the safe operation of the maintenance platform.
