Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a large bottom shaft support wear-resistant device. Background Art
[0002] A gate is a control facility for closing and opening a discharge (release) water channel. It is an important part of a hydraulic structure and can be used to intercept water flow, control water level, regulate flow rate, discharge sediment and floating objects, etc.; the gate includes a rotating gate and a vertical gate. When setting a rotating gate, the lower end of the gate plate rotates around the bottom shaft, and a support component for supporting its rotation needs to be arranged outside the bottom shaft. There is a lack of wear-resistant devices outside the traditional bottom shaft, resulting in the non-wear-resistant support part of the bottom shaft, which is not conducive to improving the service life of the product.
[0003] Based on this, a large bottom shaft support wear-resistant device is provided now, which can eliminate the drawbacks of the existing device. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a large bottom shaft support wear-resistant device, which solves the problem of non-wear resistance in the prior art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A large bottom shaft support wear-resistant device includes a wear-resistant outer sleeve arranged outside the bottom shaft. The wear-resistant outer sleeve includes one or more wear-resistant rings. A plurality of welding filling holes are distributed on the surface of the wear-resistant ring. Welding filler is filled between the welding filling holes and the auxiliary connection holes for fixing the wear-resistant ring on the surface of the bottom shaft. The outer end face of the welding filler is flush with the surface of the wear-resistant ring.
[0007] On the basis of the above technical solutions, the utility model also provides the following optional technical solutions:
[0008] In an optional solution: A plurality of auxiliary connection holes are distributed on the surface of the bottom shaft where the welding filling holes are located.
[0009] In an optional solution: The diameter of the welding filling hole is not less than 10 mm.
[0010] In an optional solution: A polishing layer is provided on the end of the welding filler and the surface of the wear-resistant ring.
[0011] In an optional solution: A plurality of filler side notches are distributed at both ends of the wear-resistant ring.
[0012] In an optional solution: The wear-resistant ring is made of stainless steel material and its thickness is at least 10 mm.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] The utility model greatly improves the wear resistance between it and the supporting components by constructing a stainless steel protective ring outside the bottom shaft, thus greatly improving the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0021] As Figures 1-4 shown, the embodiment of the utility model provides a large bottom shaft support wear-resistant device, including a wear-resistant outer sleeve 200 arranged outside the bottom shaft 100. The wear-resistant outer sleeve 200 includes one or more wear-resistant rings 201. A plurality of welding filling holes 202 are distributed on the surface of the wear-resistant ring 201. A plurality of auxiliary connection holes are distributed on the surface of the bottom shaft 100 where the welding filling holes 202 are located. A welding filler 203 is filled between the welding filling holes 202 and the auxiliary connection holes for fixing the wear-resistant ring 201 on the surface of the bottom shaft 100. The outer end surface of the welding filler 203 is flush with the surface of the wear-resistant ring 201, and a polishing layer is provided on the end of the welding filler 203 and the surface of the wear-resistant ring 201, so that the bottom shaft 100 rotates more smoothly;
[0022] Figure 2 and 3 shown, a plurality of filler side notches 204 are distributed at both ends of the wear-resistant ring 201, which can further increase the welding filling amount during side welding and improve the connection strength;
[0023] The wear-resistant ring 201 is made of stainless steel material with a thickness of at least 10 mm. By constructing a wear-resistant layer at the key position outside the bottom shaft 100, the service life of the equipment is effectively improved without significantly increasing the cost;
[0024] Figure 4 As shown, first complete the preliminary docking, then perform spot welding filling, then cut off the excess part, and finally perform polishing operations.
[0025] Working principle: In actual use, first put the wear-resistant ring 201 on the target position outside the bottom shaft 100, then align the welding filling holes 202 with the auxiliary connection holes, and then perform welding operations at the positions of each welding filling hole 202 to construct multiple welding fillers 203 that connect the wear-resistant ring 201 and the bottom shaft 100. Then, cut the welding fillers 203 protruding outside the wear-resistant ring 201 through a lathe, and polish the outside of the wear-resistant ring 201 through a polishing device, so as to reduce the friction coefficient of the support area and facilitate the subsequent rotational connection.
[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
