Description

Technical Field

[0001] A drive shaft protection device, belonging to the field of drive shaft technology. Background Technology

[0002] The power source for a loom is usually located high up, separated from the loom by a partition. This serves two purposes: first, to prevent small debris such as fabric scraps from entering the power source; and second, to isolate the noise generated by the power source, providing a relatively quiet environment for the weavers. Since the drive shaft connecting the power source and the loom extends from a high position, the partition needs to have through holes for the drive shaft to pass through. This allows small debris such as fabric scraps to pass through the partition and enter the power source, offering limited protection. Furthermore, the drive shaft requires regular lubrication; the vibration generated by the power source driving the vertically positioned drive shaft causes some grease to splash, resulting in contamination. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a transmission shaft protection device, which is set on the outside of the transmission shaft to prevent debris from entering the upper part of the partition through the through hole and entering the power unit, and the protection device is easy to disassemble and assemble.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: the transmission shaft protection device includes a mounting base, a connecting cover, a protective cover, and a fixing bracket.

[0016] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0017] Reference Figures 1-2In the textile industry, the power unit 6 is typically located on the upper side of a partition 7. The partition 7 has a through hole for the drive shaft 5 to pass through. The drive shaft 5 connects to the loom below through the through hole. A drive shaft protection device is located on the outside of the drive shaft 5, including a mounting base 1, a connecting cover 2, a protective cover 3, and a fixing bracket 4. The mounting base 1, connecting cover 2, and protective cover 3 are located on the outside of the drive shaft 5. The mounting base 1 is located below the power unit 6 and is fixedly connected to it. The connecting cover 2 is located below the mounting base 1 and is used to connect to the protective cover 3. The protective cover 3 extends through the through hole to the bottom of the partition 7. One end of the fixing bracket 4 is connected to the power unit 6, and the other end is connected to the protective cover 3. The power unit 6 of this invention can be any mechanism capable of generating power, such as an engine or motor.

[0018] Specifically, the rectangular mounting base 1 is hollow inside and has a through bottom. Its top plate is bolted to the power unit 6. The connecting cover 2 is also hollow inside and has a through top and bottom. The connecting cover 2 is bolted to the mounting base 1. The mounting base 1 and the connecting cover 2 cover the bottom of the power unit 6. The top plate of the mounting base 1 has a through hole for the drive shaft 5 to pass through. After passing through the mounting base 1 and the connecting cover 2, the drive shaft 5 extends to the bottom of the partition 7 and connects to the loom.

[0019] The connecting cover 2 includes a connecting part 201 and a locking part 202. The connecting part 201 and the locking part 202 are integrally formed. The arc-shaped locking part 202 is located on the lower side of the connecting part 201 and extends outward. The connecting part 201 is connected to the side of the mounting base 1 by bolts.

[0020] The protective cover 3 includes a first protective cover 301 and a second protective cover 302. The first protective cover 301 and the second protective cover 302 have the same shape. The connecting parts of the first protective cover 301 and the second protective cover 302 each have a bolted fixing part 303 protruding outward, and the two are fixed by bolts. The upper parts of the first protective cover 301 and the second protective cover 302 are connected to form an arc shape, and the lower parts of the first protective cover 301 and the second protective cover 302 are connected to form a cylinder shape. In this utility model, the upper and lower parts are set separately and connected by bolts. In other embodiments, the upper and lower parts can also be set as one piece.

[0021] The protective cover 3 of this utility model is made of rubber. The upper parts of the first protective cover 301 and the second protective cover 302 are connected to form an arc shape. The diameter of the arc shape gradually increases from top to bottom, and the minimum diameter of the arc shape is equal to or less than the diameter of the locking part 202. Therefore, after being enclosed, it can be locked by the locking part 202. The upper parts of the first protective cover 301 and the second protective cover 302, together with the locking part 202, form a spherical enclosing space. The universal joint components on the drive shaft 5 can be set in this space, resulting in a simple structure.

[0022] The lower parts of the first protective cover 301 and the second protective cover 302 are connected to form a cylindrical cover. The diameter of the cover is smaller than the diameter of the through hole. The cover extends through the partition 7 to the lower side of the partition 7. Compared with the drive shaft 5 directly passing through the through hole, the diameter of the cover is much smaller than the diameter of the through hole, so that debris is not easy to enter the cover, thus protecting the power unit 6.

[0023] Reference Figure 3 The fixed bracket 4 includes a vertical connecting part and a horizontal connecting part. The upper end of the vertical connecting part is connected to the power device 6, and the lower end is connected to the horizontal connecting part. The end of the horizontal connecting part protrudes outward and is provided with a fixed mounting part 401, which is parallel to the fixed part 303.

[0024] One end of the fixed mounting part 401 is rectangular, and the other end protrudes to both sides of the rectangle to form a trapezoidal connecting part. The connecting part fits into the fixed part 303. The connecting part is provided with bolt holes in the same position as the fixed part 303. The two halves of the lower cover 302 are connected to the connecting part in sequence by bolts.

[0025] Reference Figure 4 The vertical connecting part consists of a first connecting part 402 and a second connecting part 403. The first connecting part 402 and the second connecting part 403 are connected by bolts. The upper end of the second connecting part 403 is provided with a vertical elongated hole 404, and the first connecting part 402 is provided with bolt holes. Bolts are placed in the bolt holes and the elongated hole 404, and both ends are tightened with nuts. By setting the bolts at different positions in the elongated hole 404, the length of the overlapping part of the first connecting part 402 and the second connecting part 403 can be adjusted, thereby adjusting the installation height of the protective cover 3.

[0026] Work process: When installing the protective cover 3, the upper parts of the first protective cover 301 and the second protective cover 302 are placed around the outside of the locking part 202. The first protective cover 301 and the second protective cover 302 are connected into a whole by bolts. The two bolts corresponding to the fixing mounting part 401 of the fixing bracket 4 are not tightened at first. After the lower cover is extended to the lower side of the partition 7, the fixing mounting part 401 is attached to the fixing part 303, and the two bolts are tightened to fix it. When disassembly is required for maintenance, the fixing bracket 4 is separated from the cover first, then the bolts are removed, and the first protective cover 301 and the second protective cover 302 are separated to allow maintenance of the drive shaft 5.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
