Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flanges, in particular to a flange for repairing a shaft sleeve. Background Art
[0002] Due to welding quality problems, the weld seams of the shaft sleeves installed on the transfer vehicle are cracked. To repair the shaft sleeve welds, the welding defects must be completely removed before repair welding. Due to limited on-site conditions, such as the lack of disassembly and assembly equipment, and the very narrow space at this location, grinding and repair welding operations are extremely difficult. Therefore, it is necessary to design a flange to solve the problem of repairing cracked shaft sleeves in a narrow space. Utility Model Content
[0003] In view of this, in order to solve the above problems, the purpose of the utility model is to provide a flange for repairing a shaft sleeve, comprising:
[0004] Two split flanges, both of which are semicircular, the upper surfaces of both ends of the opening of each split flange are chamfered, the two flanges are operably connected to form a flange ring, and the flange ring has a channel portion.
[0005] In another preferred embodiment, the two split flanges are connected by welding.
[0006] In another preferred embodiment, the channel portion includes a first channel portion, a second channel portion and a third channel portion that are interconnected, one end of the first channel portion is connected to one end of the second channel portion, and the other end of the second channel portion is connected to one end of the third channel portion.
[0007] In another preferred embodiment, the inner diameter of the first channel portion is greater than the inner diameter of the second channel portion, and the inner diameter of one end of the third channel portion is equal to the inner diameter of the second channel portion.
[0008] In another preferred embodiment, the inner diameter of the third channel portion increases gradually from one end to the other end.
[0009] Due to the adoption of the above technical solution, the utility model has the following positive effects compared with the prior art: through the application of the utility model, a flange for repairing a shaft sleeve is provided, two split flanges are sleeved on the cracked part of the shaft sleeve, and then the two split flanges are welded, without the need to disassemble any parts, return to the factory for repair, and grind the cracked part of the shaft sleeve, and the shaft sleeve can be directly repaired, saving time and effort.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0015] like Figures 1 to 3 As shown, a flange for repairing a shaft sleeve according to a preferred embodiment is shown, comprising:
[0016] Two split flanges 1 are both semicircularly arranged. The upper surfaces of both ends of the opening of each split flange 1 are both provided with chamfers 2. The two split flanges are operably connected to form a flange ring 3. The flange ring 3 has a channel portion.
[0017] In actual use, the two-part flange 1 is directly put on the crack of the sleeve, and then the two-part flange 1 is welded into a flange ring 3, and then the flange ring 3 is welded to the sleeve and the upper body respectively. When welding, the welding position of the two-part flange 1 avoids the weld of the original crack of the sleeve to avoid the weld from cracking again.
[0018] Furthermore, as a preferred embodiment, the two split flanges 1 are connected by welding.
[0019] Further, as a preferred embodiment, the channel portion includes a first channel portion 4, a second channel portion 5 and a third channel portion 6 which are interconnected, one end of the first channel portion 4 is connected to one end of the second channel portion 5, and the other end of the second channel portion 5 is connected to one end of the third channel portion 6.
[0020] Further, as a preferred embodiment, the inner diameter of the first channel portion 4 is greater than the inner diameter of the second channel portion 5 , and the inner diameter of one end of the third channel portion 6 is equal to the inner diameter of the second channel portion 5 .
[0021] Further, as a preferred embodiment, the inner diameter of the third channel portion 6 is gradually increased from one end to the other end.
[0022] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
