Description

Technical Field

[0001] The utility model relates to the technical field of lifting and transmission, in particular to an auxiliary tooling for replacing furnace tubes. Background Art

[0002] High temperature tube furnaces play a key role in the manufacture of photovoltaic cells. In this manufacturing process, a series of process steps are involved, including boron diffusion, low pressure oxidation and plasma enhanced chemical vapor deposition. These steps need to be carried out in a high temperature environment, and high temperature rod furnaces are designed to provide such heating conditions. Generally speaking, there are multiple furnace tubes inside a high temperature rod furnace, and the most common configuration is 6. These furnace tubes are responsible for carrying and conducting the heat energy of the heating source to ensure the smooth progress of the process steps. However, over time, the furnace tubes may expire or be damaged and need to be replaced.

[0003] At present, when replacing the furnace tube, the operator uses a ladder to lift the new furnace tube to a certain height and then slowly inserts it into the furnace. This process requires 6 to 10 operators to cooperate and the labor cost is high. In order to improve the loading and unloading efficiency of the furnace tube, a lifting device or a climbing vehicle is also used for assistance. When using a lifting device, the furnace tube is fixed with a strap and then lifted by a cable, which reduces the difficulty of lifting the furnace rod. However, when moving the furnace tube into the furnace, the end of the furnace tube away from the furnace still needs to be held horizontally by manpower to avoid the end of the furnace tube entering the furnace from colliding with the furnace and being damaged. The overall operation is difficult. When using a climbing vehicle, the furnace rod is lifted to the height of the furnace and then pushed in manually. However, since the furnace rod is a cylindrical structure, it is easy to deviate from the track when pushed in, and it is easy to collide with the equipment and be damaged, and it is also very easy to be damaged by friction with the climbing vehicle.

[0033] See also Figure 1 and Figure 2 An embodiment of the present application provides an auxiliary tooling for furnace tube replacement, which includes a carrier frame 1, a roller assembly, a hoisting assembly, a support assembly 4 and a detection component 5.

[0034] Specifically, the support frame 1 is used to support the furnace tube 10. The support frame 1 is a cylindrical frame structure formed by connecting at least three fixing rings 11 through a plurality of cross bars 12. The at least three fixing rings 11 are coaxial and spaced apart, and the plurality of cross bars 12 are spaced apart and arranged outside the at least three fixing rings 11.
