Description

Technical Field

[0001] The utility model relates to the technical field of Bailey sheets, in particular to automatic rust and paint removal equipment for Bailey sheet maintenance. Background Art

[0002] Baileys, also known as Bailey frames, Bailey beams or trusses, were first invented by a British engineer during World War II to solve the need for rapid bridge erection during the war and were named after him. They can be used for highway bridges, assembling gantry cranes, guide beams, bridge erection machines, hanging baskets, etc. Baileys have the characteristics of simple structure, convenient transportation, fast erection, large load capacity, good interchangeability and strong adaptability. After using Baileys for a period of time, a large amount of rust will be generated on the surface. If these rusts are not cleared in time, they will become more and more with the passage of time, thus affecting the overall performance of the Baileys and causing the performance of the Baileys to decline. Therefore, every period of time, people will perform maintenance work on the Baileys that have been used for a long time. Maintenance generally involves rust removal, paint removal, shaping and repainting, so that the Baileys can be used again without damaging their performance. Most of the existing Bailey plate repair and maintenance work is done manually, with the rust on the Bailey plate being removed by the primitive method of knocking, and then the paint being removed by solution, which is time-consuming and labor-intensive, and has low work efficiency. Even if a lot of human resources are wasted on repair and maintenance, the daily repair and maintenance volume is not high. Utility Model Content

[0012] Working time / working principle of this utility model:

[0013] Workers use a crane to hang the Bailey pieces for maintenance on the hanging rod on the right side of the equipment. The conveying mechanism transports the Bailey pieces suspended on the fixed mechanism to the immersion mechanism through chains and pulleys. At the same time, the lifting device raises the height of the Bailey pieces. When the conveying mechanism transports the Bailey pieces to the top of the immersion tank, the conveying is stopped. At the same time, the lifting device lowers the Bailey pieces to allow the Bailey pieces to be completely immersed in the immersion tank. The electric air pumps on both sides of the immersion tank are energized to give power to the air nozzles. The air nozzles blow the solution in the immersion tank to fully react chemically with the rust and paint on the Bailey pieces. At the same time, the lifting device rhythmically rises and lowers the height of the Bailey pieces to allow the Bailey pieces to fully react chemically with the solution to remove the paint and rust on the Bailey pieces. After working for a period of time, the lifting device raises the Bailey pieces, and the conveying device transports the Bailey pieces to the circulation cleaning mechanism to remove the unsoaked Bailey pieces. The Bailey sheet is transported to the soaking pool to continue the previous link. When the conveying mechanism transports the Bailey sheet between two high-pressure cleaning devices, the conveying is stopped, and the high-pressure cleaning device and the electric air pump on the device are energized to work, and the Bailey sheet is high-pressure cleaned. The cleaned water flows into the water collecting tank along the collection tank, and the electric air pump pumps the water in the water collecting tank to the recovery device through the pipeline for filtration, recovery and harmless treatment, and the harmless water is transported back to the high-pressure cleaning device through the electric air pump for recycling. After a period of cleaning, the conveying mechanism transports the cleaned Bailey sheet to the drying mechanism, and transports the next soaked Bailey sheet to the previous link. The drying mechanism uses a heating device to dry the Bailey sheet that is continuously transported. The dried Bailey sheet is transported to the next link through the conveying mechanism for re-spraying.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The immersion mechanism of the equipment includes a immersion pool for soaking Bailey pieces, which is filled with a solution for dissolving rust and paint. Electric air pumps and air nozzles are also provided on both sides of the immersion pool. When the Bailey piece is immersed in the immersion pool, the air nozzle blows the solution through the electric air pump to immerse the Bailey piece in all directions, so that the Bailey piece being repaired and maintained can fully react chemically with the solution, so that the rust and paint on the Bailey piece can be better removed, thereby improving the rust and paint removal effect of the equipment.

[0016] The circulating cleaning mechanism of this equipment includes a high-pressure cleaning device, a collecting tank, a water collecting tank and a recovery device. It can not only carefully clean the soaked Bailey sheet, but also control the rise and fall of the Bailey sheet through the lifting device to further remove the stubborn rust and paint remaining on the Bailey sheet, so as to further improve the rust and paint removal effect of the equipment. In addition, the recycling and reuse of waste water effectively reduces the consumption of water resources, saves water resources, and reduces maintenance costs.

[0017] This equipment can transport the Bailey pieces for maintenance to various institutions through the conveying mechanism for rust and paint removal. It has a high degree of automation and only requires a small number of workers to lift the Bailey pieces into the equipment through a crane. By starting the equipment, the Bailey pieces can be continuously maintained, saving human resources, improving work efficiency, and further reducing maintenance costs.
