[0020] To better understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1

[0023] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the present utility model provides a protective shaft cover plate, which includes a cover plate main body 1. One side of the cover plate main body 1 is fixedly connected with a positioning rod 13. Both ends of the positioning rod 13 are fixedly connected with bent rods 6. The positioning rod 13 is located at the bent part of the bent rod 6. One end of the bent rod 6 is rotatably connected with an adapter rod 7. The other end of the adapter rod 7 is rotatably connected with an adjusting rod 8. The adjusting rod 8 is parallel to one of the bent rods 6. One side of the adjusting rod 8 is fixedly connected with a rotating rod 11. The outer wall of the rotating rod 11 is fixedly connected with a support plate 10. One side of the support plate 10 is fixedly connected with a protective plate 2. The protective plate 2 is located directly above the support plate 10.

[0024] The following specifically describes the specific settings and functions of this embodiment. When in use, the cover plate main body 1 is deployed above the shaft, and at the same time, the protective plate 2 is arranged above the cover plate main body 1 and is parallel to the cover plate main body 1. The space left between them is sufficient for buffering. When there are falling objects above, it can play a role in protecting the cover plate main body 1, avoiding the impact force being directly transmitted to the base surface through the cover plate main body 1, and at the same time playing a role in protecting the cover plate main body 1 and the base surface.

[0025] The edge of the protective plate 2 is provided with a support plate 10. The adjusting rods 8 at both ends of the rotating rod 11 in the support plate 10 are connected to the bent rods 6 at both ends of the positioning rod 13 through the adapter rod 7. When deploying the cover plate main body 1, the rotation of the cover plate main body 1 will drive the bent rod 6 through the positioning rod 13. The bent rod 6 drives the adjusting rod 8 through the adapter rod 7, and then changes the angle of the support plate 10 through the rotating rod 11, so that the protective plate 2 directly covers above the cover plate main body 1. When deploying the cover plate main body 1, the protective plate 2 can be deployed synchronously, and when removing the cover plate main body 1, the protective plate 2 can also be removed synchronously.

[0026] Embodiment 2

[0027] As Figure 1 and Figure 2As shown in the figure, a positioning base 3 is provided on one side of the cover plate body 1. A vertical plate 4 is fixedly installed on the upper surface of the positioning base 3. A positioning rod 13 is rotatably installed in the middle of the vertical plate 4. A rotating rod 11 is rotatably installed at the top of the vertical plate 4. An electric cylinder 5 is rotatably installed on the top of the positioning base 3. One end of the piston rod of the electric cylinder 5 is fixedly connected with an adapter head 9. There is a rotational connection between the adapter head 9 and the other end of the bent rod 6. A positioning groove 12 is provided at the junction of the bent rod 6 and the adapter head 9. The upper surface of the positioning base 3 is provided with an inclined surface. The electric cylinder 5 is located above the inclined surface.

[0028] The effect achieved by the entire embodiment is that the positioning base 3 determines the position of the cover plate body 1 through the vertical plate 4. When deploying the cover plate body 1, the positioning base 3 can be fixed near the shaft. The positioning rod 13 at the edge of the cover plate body 1 is installed in the vertical plate 4, leaving a gap between the cover plate body 1 and the base surface, providing more operating space.

[0029] The angle of the cover plate body 1 is controlled by the electric cylinder 5. When the piston rod of the electric cylinder 5 retracts, it drives the bent rod 6. The bent rod 6 directly drives the positioning rod 13 to rotate, covering the cover plate body 1 on the shaft. When moving the cover plate body 1 away, the piston rod of the electric cylinder 5 is pushed out, rotating the cover plate body 1 and the protective plate 2 away from the shaft at the same time. The existence of the positioning groove 12 provides enough movement space for the adapter head 9. At the same time, the existence of the inclined surface also provides movement space for the electric cylinder 5.

[0030] The usage method and working principle of this device: When deploying the cover plate body 1, deploy the positioning base 3 near the shaft. Then, the piston rod of the electric cylinder 5 retracts, driving the bent rod 6 through the adapter head 9. By rotating the positioning rod 13, the cover plate body 1 is covered on the shaft. A gap is left between the cover plate body 1 and the base surface, providing more operating space. During the rotation of the bent rod 6, the angle of the steering rod 8 is changed through the connecting rod 7, causing the rotating rod 11 to rotate and changing the angle of the support plate 10, so that the protective plate 2 covers the cover plate body 1. When there are falling objects above, the protective plate 2 can protect the cover plate body 1, preventing the impact force from directly being transmitted to the base surface through the cover plate body 1, and playing a role in protecting both the cover plate body 1 and the base surface. When moving the cover plate body 1 away, the piston rod of the electric cylinder 5 is pushed out, rotating the cover plate body 1 and the protective plate 2 away from the shaft at the same time.

[0031] The above description is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
