Description

Technical Field

[0001] The invention discloses an intelligent monitoring and deviation correction system for a digital display visual large-span gantry crane, belonging to the technical field of gantry cranes. Background Art

[0002] Gantry crane is a variation of bridge crane, also called gantry crane. It is mainly used for loading and unloading of outdoor cargo yards, material yards and bulk cargo. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and is widely used in port cargo yards. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam, which can walk directly on the ground track, and the two ends of the main beam can have outward cantilever beams.

[0003] In the prior art, the existing large-span gantry crane correction monitoring is not convenient enough. During the operation of the large-span gantry crane, due to the different running resistance of the legs on both sides, wheel slippage, wheel diameter difference, and the different running resistance caused by the height and parallel deviation of the trolley track, the rigid and flexible legs will produce different speeds after running for a period of time. One leg is ahead of the other leg. When the leading amount (or deflection) exceeds a certain value, the crane gantry structure will deform greatly, which will increase the running resistance of the mechanism and the internal force of the metal components, causing the running motor to burn out or the metal components to be damaged, thereby reducing the performance and service life of the drive device and the metal components, and even making the crane unable to work. Now there is an urgent need for a digital display visual large-span gantry crane intelligent monitoring and correction system to solve the above problems. Summary of the invention

[0025] An internal thread is engraved on the inner annular side of the cylindrical groove 25, and an external thread is engraved on the annular side of the infrared laser pen 26, and the external thread is meshed with the internal thread, and the meshing of the external thread and the internal thread facilitates the disassembly and assembly of the infrared laser pen 26.

[0026] An analog / digital converter 281, a single-chip microcomputer 282, a memory 283 and a digital / analog converter 284 are welded on the printed circuit board 28. The analog / digital converter 281, the single-chip microcomputer 282, the memory 283 and the digital / analog converter 284 on the printed circuit board 28 are all electrically connected to the DC-DC power supply module 29, and infrared sensing is used to facilitate the correction monitoring of the gantry crane.

[0027] A display screen is installed on the upper side of the front end surface of the controller 6, and a high-definition tempered film is pasted on the front end surface of the display screen. The display screen is used to display the deviation correction data of the gantry crane.

[0030] As an embodiment of the present invention: a cylindrical groove 25 is opened inside the right end face of the supporting leg 1, and the inner annular side face of the cylindrical groove 25 is engraved with an internal thread, and the annular side face of the infrared laser pen 26 is engraved with an external thread.
