[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] like Figure 1 to Figure 3 As shown, the adjustable platform provided in the embodiment of the present application is arranged inside the conical material tank, and the adjustable platform includes a first platform 1, a second platform 2 and an adjusting rod 3.

[0038] The first platform 1 is fixedly connected with a first connection part 11, which is internally penetrated and has a first thread on its inner wall. The second platform 2 is fixedly connected with a second connection part 21, which is internally penetrated and has a second thread on its inner wall, and the second thread has an opposite rotation direction to the first thread. The adjusting rod 3 is installed inside the first connection part 11 and the second connection part 21, and an external thread is provided on the outer peripheral surface of the adjusting rod 3. The external thread of the adjusting rod 3 is threadedly matched with the first thread and the second thread. The rotation of the adjusting rod 3 around its own axis can drive the first platform 1 and the second platform 2 to move closer to or away from each other along the length direction of the adjusting rod 3, and the first platform 1 and the second platform 2 can be supported on the inner wall of the conical tank.

[0039] When the adjusting rod 3 is rotated, since the external thread of the adjusting rod 3 is threadedly matched with the first thread and the second thread, and the second thread and the first thread have opposite rotation directions, the rotation of the adjusting rod 3 can drive the first connecting part 11 and the second connecting part 21 to move relative to each other, that is, the first connecting part 11 and the second connecting part 21 are moved closer to each other or farther away from each other, thereby driving the first platform 1 and the second platform 2 to move closer to each other or farther away from each other. In this way, when using the adjustable platform, the distance between the first platform 1 and the second platform 2 can be adjusted according to the size of the construction position inside the conical tank. After the adjustment is completed, the first platform 1 and the second platform 2 are supported on the inner wall of the conical tank, and the operator can stand on the adjustable platform to work.

[0040] The adjustable platform provided in the embodiment of the present application can adjust the distance between the first platform 1 and the second platform 2 through the adjusting rod 3. When the distance between the first platform 1 and the second platform 2 is small, the adjustable platform is suitable for the position with a smaller inner diameter of the conical tank. When the distance between the first platform 1 and the second platform 2 is large, the adjustable platform is suitable for the position with a larger inner diameter of the conical tank. In this way, the user can adjust the distance between the first platform 1 and the second platform 2 according to the size of the required construction position, so that the adjustable platform can meet the operations at different positions inside the conical tank.

[0041] The first connection portion 11 can be welded on the first platform 1 , and the second connection portion 21 can be welded on the second platform 2 .

[0042] In some embodiments, a slot (not shown) is provided on the inner wall of the conical tank, and the first platform 1 and the second platform 2 can be snapped into the slot. By providing the slot as a supporting structure for the first platform 1 and the second platform 2, the structure is simple and easy to process.

[0043] Of course, the structure for supporting the first platform 1 and the second platform 2 on the inner wall of the conical tank is not limited to the slot. In other embodiments, for example, a supporting platform may be provided on the inner wall of the conical tank, and the first platform 1 and the second platform 2 may be placed on top of the supporting platform.

[0044] In some embodiments, the first connection part 11 and the second connection part 21 are nuts, and the adjustment rod 3 is a lead screw. In this way, the first connection part 11, the second connection part 21 and the adjustment rod 3 are all set as universal parts, which are easy to obtain and can omit the design and manufacturing process.

[0045] In some embodiments, the first thread, the second thread and the external thread of the adjusting rod 3 are all trapezoidal threads. The trapezoidal thread can provide a larger contact area when the threads are mated, and has better load-bearing capacity and wear resistance.

[0046] like Figure 1 As shown, in some embodiments, an adjusting member 4 is fixedly sleeved on the adjusting rod 3, and the adjusting member 4 is located between the first connecting portion 11 and the second connecting portion 21, and the adjusting member 4 is configured to engage with a tool for rotating the adjusting rod 3. Exemplarily, the tool for rotating the adjusting rod 3 may be a wrench.

[0047] By providing the adjusting member 4, the convenience for the user to use a tool to rotate the adjusting member 4 is improved, which is beneficial to improving the adjustment efficiency of the adjustable platform.

[0048] Optionally, the cross-sectional shape of the adjusting member 4 is hexagonal, that is, the adjusting member 4 is in an outer hexagonal shape. Such a shape setting is conducive to improving the contact stability between the tool and the adjusting member 4 and avoiding slipping during the rotation process.

[0049] like Figure 1 As shown, in some embodiments, the first connection portion 11 is disposed at an end of the first platform 1 close to the second platform 2 , and the second connection portion 21 is disposed at an end of the second platform 2 close to the first platform 1 .

[0050] Through such an arrangement, compared with respectively arranging the first connecting portion 11 and the second connecting portion 21 at the middle positions of the first platform 1 and the second platform 2, the first platform 1 and the second platform 2 can move relative to each other over a longer distance, thereby making the overall size adjustment range of the adjustable platform wider and making the adjustable platform more adaptable.

[0051] like Figure 1 As shown, in some embodiments, two first connection parts 11 are arranged at intervals on the first platform 1, and two second connection parts 21 are arranged at intervals on the second platform 2, the first connection parts 11 and the second connection parts 21 correspond to each other, and the number of the adjustment rods 3 is set to two, and each adjustment rod 3 is installed inside the first connection part 11 and the corresponding second connection part 21. Such a configuration is conducive to improving the connection strength between the adjustment rod 3 and the first platform 1 and the second platform 2, and further conducive to improving the stability of the first platform 1 and the second platform 2.

[0052] Furthermore, the two adjusting rods 3 are symmetrically arranged. In this way, the two symmetrically arranged adjusting rods 3 can make the forces on the first platform 1 and the second platform 2 more balanced.

[0053] In some embodiments, when the distance between the first platform 1 and the second platform 2 is the smallest, one end of the adjusting rod 3 does not extend beyond the first platform 1, and the other end of the adjusting rod 3 does not extend beyond the second platform 2. This arrangement ensures that both ends of the adjusting rod 3 will never extend beyond the first platform 1 and the second platform 2, thereby preventing the adjusting rod 3 from affecting the relative fixation between the first platform 1 and the second platform 2 and the inner wall of the conical tank.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
