Description

Technical Field

[0001] This utility model relates to the field of engineering vessel manufacturing technology, specifically to an intermediate shaft for an emergency engineering vessel. Background Technology

[0002] The intermediate shaft is a connecting shaft located between the main motor and the reducer, or between the main motor and the gear housing, or between the main motor and the universal joint shaft. A shaft is a cylindrical object that passes through the center of a bearing, wheel, or gear; however, some are square. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, and different sections can have different diameters. The rotating parts in the machine are mounted on the shaft. Currently, the intermediate shafts of emergency engineering vessels do not have a sleeve on the outside during application. Over time, the intermediate shaft is prone to wear, leading to a decrease in performance. To address these issues, a new intermediate shaft for emergency engineering vessels is proposed.

[0003] Publication number CN219299762U discloses a marine intermediate shaft, including a connecting section. One end of the connecting section is fixedly connected to a flange, and the other side of the flange is fixedly connected to a shaft body. The surface of the shaft body is provided with screw holes, and the outside of the shaft body is provided with wear-resistant steel plates. The wear-resistant steel plates are symmetrically arranged and fixedly connected to the shaft body by a fixing mechanism. In this utility model, the outside of the shaft body is provided with wear-resistant steel plates, and both ends of the wear-resistant steel plates are respectively provided with clamping plates and clamping grooves. The wear-resistant steel plates are connected end to end, and the clamping plates and clamping grooves are used to connect them, which facilitates the quick positioning of the wear-resistant steel plates and improves the installation accuracy of the wear-resistant steel plates. At the same time, the surface of the wear-resistant steel plates is provided with mounting holes, which facilitates the use of bolts to fix the assembled wear-resistant steel plates to the shaft body, improves the overall installation accuracy and strength, facilitates the assembly by the staff, and meets the usage requirements.

[0004] Regarding the aforementioned prior art, the inventors believe that the following shortcomings exist: The shaft body is externally fitted with a wear-resistant steel plate, and both ends of the wear-resistant steel plate are respectively provided with a retaining plate and a retaining groove. The wear-resistant steel plates are connected end-to-end, and the retaining plate and retaining groove are used to facilitate quick positioning of the wear-resistant steel plate, improving the installation accuracy of the wear-resistant steel plate. Simultaneously, the surface of the wear-resistant steel plate is provided with mounting holes, facilitating the use of bolts to fix the assembled wear-resistant steel plate to the shaft body, improving overall installation accuracy and strength, and making assembly convenient for workers to meet usage requirements. However, the connection between the wear-resistant steel plate and the shaft body has certain limitations. During prolonged use, the inner diameter of the shaft may shrink, leading to gaps between the steel plate and the shaft body, ultimately causing the wear-resistant steel plate to fail. Utility Model Content

[0005] The purpose of this utility model is to provide an intermediate shaft for an emergency engineering vessel, to solve the problem mentioned in the background art where the shaft body is externally fitted with a wear-resistant steel plate, and both ends of the wear-resistant steel plate are respectively provided with a clamping plate and a clamping groove. The wear-resistant steel plates are connected end to end, and the clamping plate and the clamping groove are used to connect them, which facilitates the quick positioning of the wear-resistant steel plate and improves the installation accuracy of the wear-resistant steel plate. At the same time, the surface of the wear-resistant steel plate is provided with mounting holes, which facilitates the use of bolts to fix the assembled wear-resistant steel plate to the shaft body, improves the overall installation accuracy and strength, facilitates the assembly by the staff, and meets the usage requirements. However, the connection between the wear-resistant steel plate and the shaft body has certain limitations. When the shaft body is used for a long time, the inner diameter may shrink, which will lead to the gap between the steel plate and the shaft body, and ultimately cause the wear-resistant steel plate to fail.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an intermediate shaft for an emergency engineering vessel, comprising a shaft body:

[0008] A shaft connecting body is fixedly installed on the outer side of the shaft body. A second connecting groove is opened in the inner cavity of the shaft connecting body. Four connecting grooves are symmetrically opened in the second connecting body. A connecting body is fixedly connected to the left end of the shaft connecting body. A connecting external thread is fixedly connected to the outer side of the connecting body. The connecting external thread is connected to the shaft connecting body through the connecting body.

[0009] Furthermore, a wear-resistant steel plate is fixedly connected to the outer side of the shaft, and the shaft is connected to the shaft assembly through the wear-resistant steel plate, with the wear-resistant steel plate covering the outer side of the shaft.

[0010] Furthermore, the inner cavity of the shaft body is provided with a connecting groove, and two connecting grooves are symmetrically provided. The inner cavity of the shaft body is provided with a positioning groove, and four positioning grooves are symmetrically provided.

[0011] Furthermore, a shaft core is fixedly connected to the inner cavity of the shaft body, and the shaft core is fixedly disposed in the inner cavity at the center of the shaft body.

[0012] Furthermore, a bushing is movably provided on the outer side of the shaft, a limiting post is fixedly connected to the outer side of the right end of the bushing, and a connecting post is fixedly connected to the left end of the bushing, the connecting post being connected to the bushing and the limiting post.

[0013] Furthermore, the inner cavity of the bushing body is fixedly provided with a connecting internal thread, and the connecting internal thread and the connecting external thread are engaged and connected.

[0014] Furthermore, the inner cavity of the bushing body is fixedly provided with a shaft groove, and the inner diameter of the shaft groove is the same as the inner diameter of the shaft body.

[0015] This utility model has the following beneficial effects:

[0016] I. This utility model includes a shaft body. After the user places the shaft body, it is connected to the shaft connecting body via a wear-resistant steel plate on the outside. The shaft connecting body allows the right end of the shaft body to be fixedly connected via a connecting groove. Then, the shaft connecting body is connected to the connecting body and the connecting external thread. The shaft connecting body is rotated by the engagement of the connecting external thread and the connecting internal thread in the inner cavity of the bushing body. The connection of the connecting external thread and the connecting internal thread makes the connection between the shaft body and the bushing body more stable, and the shaft body will not wear down due to long-term use, resulting in a reduction in the inner diameter and ultimately insufficient restraint between the shaft body and external parts. This shaft body is connected to the bushing body via a wear-resistant steel plate, and the bushing body is connected to the external parts, ensuring the service life of the shaft body.

[0017] II. Based on the above-mentioned beneficial effects, it also includes a bushing body. After the user rotates and connects the shaft body and the bushing body through the engagement of the external thread and the internal thread, the bushing body is used to protect the outer side of the shaft body when it rotates. There is a limit post on the outer side of the bushing body, which is used to limit the position of the bushing body deflection. There are symmetrically arranged limit grooves in the inner cavity of the outer ring of the limit post to help limit the position. The inner diameter of the shaft groove in the inner cavity of the bushing body is exactly the same as the inner diameter of the shaft body. The shaft groove is used to place the shaft body without affecting its rotation. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is an intermediate shaft for an emergency engineering vessel, including shaft body 1:

[0028] A shaft connecting body 6 is fixedly installed on the outer side of the shaft body 1. A connecting groove 7 is opened in the inner cavity of the shaft connecting body 6. Four connecting grooves 7 are symmetrically opened. A connecting body 8 is fixedly connected to the left end of the shaft connecting body 6. A connecting external thread 9 is fixedly connected to the outer side of the connecting body 8. The connecting external thread 9 is connected to the shaft connecting body 6 through the connecting body 8.

[0029] A wear-resistant steel plate 2 is fixedly connected to the outer side of the shaft body 1. The shaft body 1 is connected to the shaft connector 6 through the wear-resistant steel plate 2, and the wear-resistant steel plate 2 covers the outer side of the shaft body 1.

[0030] The shaft body 1 is connected to the shaft connector 6 via a wear-resistant steel plate 2 on the outside.

[0031] The inner cavity of the shaft 1 is provided with a connecting groove 3, and there are two connecting grooves 3 symmetrically provided. The inner cavity of the shaft 1 is provided with a positioning groove 4, and there are four positioning grooves 4 symmetrically provided.

[0032] A core 5 is fixedly connected to the inner cavity of the shaft body 1, and the core 5 is fixedly located in the inner cavity at the center of the shaft body 1.

[0033] Shaft 1 is connected to external parts through connecting groove 3, and shaft 1 is positioned through positioning groove 4.

[0034] Working principle: After the user places the axle 1, the axle 1 is connected to the shaft connector 6 via a wear-resistant steel plate 2 on the outside. The shaft connector 6 is fixedly connected to the right end of the axle 1 via a connecting groove 7. Then, the shaft connector 6 is connected to the connecting body 8 and the connecting external thread 9. The shaft connector 6 is rotated by engaging the connecting internal thread 13 of the inner cavity of the bushing 10 via the connecting external thread 9. The connection between the connecting external thread 9 and the connecting internal thread 13 makes the connection between the axle 1 and the bushing 10 more stable, and the axle 1 will not wear down due to long-term use, resulting in a reduction in the inner diameter and insufficient restraint between the axle 1 and external parts. The connection between the axle 1 and the bushing 10 via the wear-resistant steel plate 2 and the bushing 10 with the external parts ensures the service life of the axle 1.

[0035] This step involves connecting the wear-resistant steel plate 2 and the bushing 10, with the bushing 10 connected to external parts, thus ensuring the service life of the shaft 1.

[0039] The inner cavity of the bushing body 10 is fixedly provided with a connecting internal thread 13, which engages with the connecting external thread 9.

[0040] The inner cavity of the bushing 10 is fixedly provided with a shaft body 1 groove, and the inner diameter of the shaft body 1 groove is the same as the inner diameter of the shaft body 1.

[0042] Working principle: After the user connects the shaft body 6 and the bushing body 10 by engaging the external thread 9 and the internal thread 13, the bushing body 10 is used to protect the outside of the shaft body 1 when it rotates. There is a limit post 11 on the outside of the bushing body 10, which limits the position of the bushing body 10. The limit post 11 is used to limit the position of the bushing body 10. The inner cavity of the outer ring of the limit post 11 is provided with symmetrically arranged limit grooves to help limit the position. The inner diameter of the shaft body 1 groove in the inner cavity of the bushing body 10 is exactly the same as the inner diameter of the shaft body 1.
