[0002] With the rapid development of the national economy, productivity and production efficiency in all walks of life need to be greatly improved. This requires the use of some large-scale equipment. The workpieces used to assemble large-scale equipment are usually large in size and weigh several tons or even more than ten tons. For example, in the production of loaders, steel structures, and offshore equipment, etc. Most of the large-scale equipment composed of these workpieces is used outdoors, even in relatively harsh working environments. Therefore, the workpieces need to undergo strict anti-corrosion treatment, such as spraying, painting, and other spraying processes. To complete these processes, multiple processing steps are often required, and different processes correspond to different studios. However, some existing factory areas are small, and conventional serial assembly lines cannot be laid out normally due to the large space they occupy. Therefore, they have to adopt a parallel arrangement. At the same time, due to the large or heavy workpieces, transportation difficulties and low efficiency arise when switching workstations. In order to complete the connection between each link, a conveying equipment is needed to assist in the connection to form a closed loop, complete the continuous processing operation, and reduce the safety hazards in the transfer process. Summary of the Invention

[0007] Furthermore, the power transmission device uses a busbar or a tank chain towline.

[0008] The technical solution of the present invention also seeks protection for a method for spraying production using a spraying process production line, which is applied to the above-mentioned aerial translation conveying equipment. The spraying process production line includes a shot blasting chamber, a paint spraying chamber, a leveling chamber, a drying chamber, and a polishing chamber, which are connected in sequence and arranged side by side on the foundation of a designated work area. A second guide rail is installed directly above each chamber body through a bracket, and its installation height is flush with the above-mentioned first guide rail. The top plates of the shot blasting chamber, paint spraying chamber, leveling chamber, drying chamber, and polishing chamber are each provided with a guide groove running through the length of each chamber body, located directly below and parallel to the second guide rail. The guide groove is provided with a width greater than the width of the chain electric hoist, and sealing strips are installed on the side walls of the guide groove. The aerial translation conveying equipment is provided with two groups, fixedly installed on the two ends of the above-mentioned chamber body, relatively parallel, wherein the aerial running track is perpendicular to the workpiece running line of each chamber body.

[0009] Furthermore, the method specifically includes the following steps:

[0010] S1. Preliminary preparations for the workpiece to enter the production line; the aerial trolley on the left first moves along the corresponding aerial walking track to the workstation of the corresponding shot blasting room, and the workpiece to be processed is placed on the support platform of the electric flat car opposite the shot blasting room. The electric flat car drives the workpiece to be processed from the outside along the flat car track to the bottom of the aerial trolley. Then, the operator uses the workpiece hook to hang it into the corresponding hanging hole on the balance beam according to the size of the workpiece. The chain electric hoist lifts the workpiece and hangs it, and the electric flat car withdraws to the starting point outside the production line.

[0011] S2. The workpiece circulates between various workstations; first, the first guide rail on the left aerial translation vehicle is aligned with the left end of the second guide rail above the shot blasting room, and the chain electric hoist runs along the first guide rail and the second guide rail above the shot blasting room to drive the workpiece into the shot blasting room for shot blasting cleaning. After the workpiece is shot blasted, the chain electric hoist drives the workpiece back to the left aerial translation vehicle; then the left aerial translation vehicle moves along the corresponding aerial walking track to the workstation of the corresponding paint spraying room, and the first guide rail on it is aligned with the left end of the second guide rail above the paint spraying room, and the chain electric hoist runs along the first guide rail and the second guide rail above the paint spraying room to drive the workpiece into the paint spraying room for painting. At this time, the right aerial translation vehicle moves along the corresponding aerial walking track to the workstation of the corresponding paint spraying room. At the right workstation of the spray painting room, the first guide rail on it is aligned with the right end of the second guide rail above the spray painting room. After painting is completed, the chain electric hoist drives the workpiece to move to the right aerial translation car; then the aerial translation cars on both sides move downward to the workstation corresponding to the leveling room, and the first guide rails on it are aligned with the two ends of the second guide rail above the leveling room, and the chain electric hoist drives the workpiece from the right side to the leveling room for volatilization and leveling, and then moves left along the guide rail to the left aerial translation car; the aerial translation cars on both sides continue to move downward to the workstation corresponding to the drying room, and the first guide rails on it are aligned with the two ends of the second guide rail above the drying room, and the chain electric hoist drives the workpiece from the left side to the drying room for drying.

[0012] S3. After the workpiece is processed, it is moved out of the production line. After the drying is completed, if the workpiece does not need to be polished, the chain electric hoist drives the workpiece out of the left side of the drying room, along the second guide rail above the drying room and the first guide rail of the left aerial horizontal car, and then returns to the left aerial horizontal car. At this time, the electric flat car facing the drying room moves along the flat car track to the bottom of the left aerial horizontal car. The chain electric hoist runs to lower the workpiece to the supporting platform of the electric flat car. The operator removes the workpiece from the workpiece hook. The electric flat car drives the workpiece along the flat car track to the process outside the production line, and all the aerial horizontal cars return to the starting position. After the drying is completed, if the workpiece needs to be polished, the chain electric hoist drives the workpiece out of the right side of the drying room. At this time, the right aerial horizontal car has moved to the corresponding workstation on the right side of the drying room. The first guide rail is aligned with the right end of the second guide rail above the drying room, and the chain electric hoist drives the workpiece to the right aerial trolley. Then the aerial trolleys on both sides move down to the corresponding workstations in the grinding room, and the first guide rails on them are aligned with the two ends of the second guide rail above the grinding room. The chain electric hoist drives the workpiece from the right to the inside of the grinding room for grinding. After grinding, it moves to the left along the guide rail to the left aerial trolley. The electric flat cart facing the grinding room moves along the flat cart track to the bottom of the left aerial trolley. The chain electric hoist lowers the workpiece to the supporting platform of the electric flat cart. The operator removes the workpiece from the workpiece hook, and the electric flat cart drives the workpiece along the flat cart track to the process outside the production line. All aerial trolleys return to their starting positions.

Then the chain electric hoist 14 is lowered and the workpiece is placed on the supporting platform of the electric flat car 20 corresponding to the drying chamber 4. The operator removes the workpiece hook 16, and the electric flat car 20 moves the workpiece along the corresponding flat car track 21 to the off-line process. If polishing is required after the drying is completed, the chain electric hoist 14 is moved out from the right side of the drying chamber 4 and enters the right aerial translation vehicle that has been advanced to the work station to complete the docking and leveling.
