Description

Technical Field

[0001] The utility model relates to the field of elevator shaft lifting platforms, and more specifically, to an elevator shaft lifting platform. Background Art

[0002] Safety production at the construction site is the primary task in engineering projects. Only on the premise of ensuring safe construction can the progress and quality of the project be guaranteed. An elevator is a necessary vertical transportation device in all buildings. The elevator shaft is one of the major edge openings at the construction site, which can facilitate construction workers to carry out mobile operations on high floors.

[0003] However, most current elevator shaft lifting platforms have the following problems:

[0004] For example, a lifting platform for elevator shaft construction with the publication number CN219753907U. Although the guardrail can rotate on the sliding rod and play a role in isolation and protection, there are certain gaps at the rotation points. After long-term use, the gaps are easily blocked by dust and impurities, affecting subsequent rotation and deployment. Moreover, small parts such as nuts are still prone to falling, making it inconvenient for convenient protection. At the same time, the use height of the guardrail is limited. If the guardrail is too high, it is easy to enter the lifting platform, and if the guardrail is too low, it is easy to fail to play a safety protection role and cannot be adjusted according to the usage situation.

[0005] Therefore, we make improvements on this and propose an elevator shaft lifting platform. Summary of the Invention

[0006] The purpose of the utility model is to address the problems of inconvenient convenient protection and inability to be adjusted according to usage situations currently existing.

[0035] The solution in Example 1 will be further introduced below in combination with the specific working mode. See the following description for details:

[0036] As Figure 8 shown, as a preferred embodiment, on the basis of the above method, further, the installation boxes 2 are distributed at equal angles on the lifting platform 1, and the side end face of the moving box 4 is in contact with the inner side face of the installation box 2, which can ensure that when the moving box 4 moves, it can move smoothly through the support of the inner side face of the installation box 2.

[0037] As Figure 8 shown, as a preferred embodiment, on the basis of the above method, further, the return springs 5 are symmetrically distributed on the left and right sides inside the moving box 4, and the return springs 5 correspond to the clamping blocks 7 through the limiting plates 6, which can ensure that the clamping of the two clamping blocks 7 can limit and fix the moving box 4.

[0038] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the limiting plate 6 is in contact with the inner side face of the moving box 4, and the cross section of the clamping block 7 is an isosceles triangle, which can ensure that the clamping block 7 in the shape of an isosceles triangle can move to one side through the action of the inclined surface.

[0039] As Figure 8 shown, as a preferred embodiment, on the basis of the above method, further, the protective nets 13 are symmetrically distributed on the left and right sides inside the push rod 10, and the protective nets 13 correspond to the material shafts 14 one by one, which can ensure that under the action of the two protective nets 13, the function of protection and isolation can be achieved.

[0040] Specifically, when this elevator shaft lifting platform is in use: Combining Figures 1-9, when the lifting platform 1 is used for lifting, the installation boxes 2 on the front, rear, left and right sides can play a role in blocking and protecting, avoiding the situation that tool parts fall off when tools are placed stably on the lifting platform 1 during use, and can prevent dust and impurities from blocking the normal use of the installation boxes 2, playing a protective role.

[0041] When the lifting platform 1 is lifted and needs to be protected, the cover plate 11 can be pulled up by pulling the pulling plate 12. When the cover plate 11 moves, it can drive the moving box 4 to move through the push rod 10. When the two moving boxes 4 move inward at the same time, the moving box 4 can move smoothly under the support of the sliding rod 3. When the moving box 4 moves, the inclined surface of the clamping block 7 on the moving box 4 is pushed by the installation box 2, and the clamping block 7 is retracted into the installation box 2 to drive the limiting plate 6 to move. When the limiting plate 6 moves upward, it can squeeze the return spring 5. When the clamping block 7 moves forward without obstruction and moves above the clamping groove 8, it drives the limiting plate 6 and the clamping block 7 to reset under the push of the return spring 5. The clamping block 7 can be clamped in the clamping groove 8 in the installation box 2 to play a limiting role and fix the use position of the cover plate 11. When the cover plate 11 moves upward, it can pull the protective net 13 upward, and the protective net 13 drives the material shaft 14 to rotate. When rotating, the scroll spring 15 can be pressed. The clamping of the moving box 4 can limit and fix the protective net 13 on the cover plate 11, and the protective net 13 can be fixed according to the use situation, which is convenient to use the protective net 13 for protective isolation.

[0042] When it is necessary to lower the cover plate 11, the pull plate 9 can be pushed to drive the limiting plate 6 to move upward. When the limiting plate 6 moves, it can drive the clamping block 7 to retract into the moving box 4. When the moving box 4 is unobstructed and the cover plate 11 is pressed downward, the cover plate 11 can drive the moving box 4 to reset through the push rod 10. After the protective net 13 is unobstructed, the material shaft 14 is wound under the force of the scroll spring 15, improving the adjustment effect.

[0043] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific embodiments.
