[0030] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 6The utility model provides a linkage protective cover device for a lifting platform, comprising a cover frame 1, a protective cover 2 that can be flipped open, at least one pull rope 3 for driving the protective cover 2 to open, and a driving frame 4. The cover frame 1 is located on one side of the lifting platform 7, and the protective cover 2 can be rotatably mounted on the cover frame 1. When the protective cover 2 is closed (in a horizontal state), the protective cover 2 is flush with the lifting platform 7. A steering wheel frame 5 is fixed to the lower side of the cover frame 1, and a steering wheel group 6 can be rotatably mounted on the steering wheel frame 5, and the steering wheel group 6 is used to steer the pull rope 3. One end of the pull rope 3 is connected to the end of the protective cover 2, and the other end of the pull rope 3 is connected to the driving frame 4 after passing the steering wheel group 6. The driving frame 4 can drive the protective cover 2 to open or close through the pull rope 3; the driving frame 4 is fixed on the external lifting platform 7, and can be lifted and lowered following the lifting platform 7. Among them, the pull rope 3 is a steel wire rope to ensure the structural strength.

[0032] The protective cover is linked to the lifting platform so that it can open and close automatically with the lifting platform, which is convenient to use. When the lifting platform is lowered, the protective cover is closed under the action of its gravity, thereby blocking the space on both sides of the lifting platform, which not only improves the safety of use but also makes it more beautiful. When the lifting platform is raised, the protective cover is flipped open by a pull rope to avoid interference with the lifting stage.

[0033] In some embodiments, Figure 2 and Figure 5 As shown, an upper guide wheel frame 8 and a lower guide wheel frame 9 are spaced apart at the lower side of the bogie frame 5, and the upper guide wheel frame 8 and the lower guide wheel frame 9 are arranged correspondingly. An upper guide wheel 10 is installed on the upper guide wheel frame 8, and a lower guide wheel 11 is installed on the lower guide wheel frame 9.

[0034] like Figure 3 and Figure 5 As shown, the pull rope 3 includes a first pull rope 31 and a second pull rope 32. One end of the first pull rope 31 is connected to the end of the protective cover plate 2. The other end of the first pull rope 31 is connected to one end of the second pull rope 32 after passing through the steering wheel group 6 and the upper guide wheel 10. The other end of the second pull rope 32 is connected to the lower end of the first pull rope 31 after passing through the lower guide wheel 11 and the upper guide wheel 10. The driving frame 4 is fixed on the second pull rope 32. In this structure, when the lifting platform 7 is raised, the lifting platform 7 drives the driving frame 4 to rise, and the driving frame 4 pulls the second pull rope 32 toward the upper side. The second pull rope 32 drives the first pull rope 31 to move downward, and then the first pull rope 31 pulls the end of the protective cover plate 2 to flip the protective cover plate 2 open. When the lifting platform 7 is lowered, the protective cover plate 2 can be gradually closed under the action of its gravity.

[0035] In some embodiments, Figure 5As shown, the first pull rope 31 and the second pull rope 32 are connected by a counterweight rod 33. The end of the first pull rope 31 close to the counterweight rod 33 is connected to a counterweight block 35 through a connecting rope 34. The gravity of the counterweight block 35 and the counterweight rod 33 always makes the protective cover 2 have a tendency to open. Through the cooperation of the counterweight rod 33 and the counterweight block 35, on the one hand, the pull rope can be tensioned, and on the other hand, the gravity direction of the counterweight rod 33 and the counterweight block 35 is consistent with the force direction of the protective cover 2 to open, which reduces the weight of manually opening the protective cover 2 and is more convenient for maintenance.

[0036] In some embodiments, Figure 2 and Figure 3 As shown, the steering wheel group 6 includes a first steering wheel 61 installed at the end of the steering wheel frame 5 and a second steering wheel 62 arranged on the steering wheel frame 5 at intervals along a straight line direction. In order to ensure the reliability of the structure, there are multiple pull ropes 3, two second steering wheels 62, and two corresponding upper guide wheels 10 and lower guide wheels 11.

[0037] In some embodiments, Figure 3 and Figure 4 As shown, a spring pin 12 is installed at the bottom of the cover frame 1. After the protective cover 2 is flipped open to a certain angle, the end of the protective cover 2 abuts against the compression spring pin 12. The spring pin 12 is provided to reset the protective cover 2 to prevent the protective cover 2 from being stuck due to excessive opening angle.

[0038] In one example, if Figure 3 and Figure 6 As shown, a connecting ear 21 is provided at the end of the protective cover plate 2, a first rotating shaft 22 is inserted into the connecting ear 21, and one end of the pull rope 3 is connected to the first rotating shaft 22 through a wire rope fastener 36. The protective cover plate 2 is rotatably connected to the cover plate frame 1 through a second rotating shaft 23, and the second rotating shaft 23 is arranged close to the first rotating shaft 22.

[0039] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0040] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
