[0038] In the related art, the basic structure of the floor protection device is disclosed, but due to the different distances between each floor and the elevator, the distance between the floor protection device and the bottom surface and the side surface of the elevator is also inconsistent, which is easy to cause the distance of the side surface or the bottom surface to be large, causing the risk of falling.

[0039] In order to solve the problems in the related art to some extent, the elevator floor protection device provided by the embodiments of the present application adjusts the distance between the bottom surface and the side surface through the bottom distance adjusting assembly, the side distance adjusting assembly and the distance measuring sensor. The bottom distance adjusting assembly and the side distance adjusting assembly adjust the distance through the hydraulic cylinder, and the distance between the elevator and the floor platform is detected in real time through the control of the distance measuring sensor and the hydraulic cylinder, and the position of the bottom support plate and the side support plate is automatically adjusted to ensure that the gap is always controlled within a safe range, effectively reducing the falling risk caused by inconsistent distance of the traditional fixed protection device.

[0040] The present application will be described below in conjunction with the drawings and specific embodiments:

[0041] In conjunction with Figures 1-4 , the elevator floor protection device provided by the embodiments of the present application includes a bottom plate assembly 10, the bottom plate assembly 10 includes a bottom plate 11; a pre-buried steel plate 12 is fixedly connected to the bottom of the bottom plate 11; a pre-buried pipe 13 is fixedly connected to the bottom of the pre-buried steel plate 12;

[0042] The bottom plate 11 is fixed on the floor plate through the pre-buried steel plate 12 and the pre-buried pipe 13, which can improve the overall strength of the protection device;

[0043] The top of the bottom plate 11 is provided with a guardrail assembly 20, which comprises guardrail columns 21 arranged on the top of the bottom plate 11, and guardrail plates 22 fixedly connected to the outer side walls of the guardrail columns 21;

[0044] There are four groups of guardrail columns 21 in total, and the guardrail plates 22 are fixed on the bottom plate 11 through the guardrail columns 21;

[0045] The outer side walls of the guardrail columns 21 are hingedly connected with protective doors 30;

[0046] There are two protective doors 30 in total, which are connected with the guardrail columns 21 in a hinged manner;

[0047] One side of the bottom plate 11 is provided with a bottom surface distance adjusting assembly 40, which comprises a bottom surface sliding seat 41 fixedly connected to one side of the bottom plate 11, a bottom surface support plate 42 slidingly connected to the top of the bottom surface sliding seat 41, a connecting block 43 fixedly connected to the top of the bottom surface support plate 42, a hydraulic cylinder support plate 44 fixedly connected to the outer side wall of the bottom plate 11, and a hydraulic cylinder 45 arranged on the top of the hydraulic cylinder support plate 44, with a telescopic end connected to one side of the bottom surface support plate 42;

[0048] Under normal circumstances, the bottom surface support plate 42 is at the innermost side to avoid affecting the operation of the elevator. When the vertical distance between the floor protection device and the cage or the landing door exceeds 150 mm, the hydraulic cylinder 45 starts to work, so that the hydraulic cylinder 45 drives the bottom surface support plate 42 to slide on the bottom surface sliding seat 41, and the bottom surface support plate 42 slides outward, so that the vertical distance between the bottom surface support plate 42 and the cage or the landing door meets the requirement (less than 150 mm);

[0049] The outer side walls of the guardrail columns 21 are provided with side distance adjusting assemblies 50, which comprise side sliding seats 51 symmetrically arranged on the outer side walls of the guardrail columns 21, side sliding grooves 52 opened on the outer side walls of the side sliding seats 51, and side support plates 53 slidingly connected to the inner walls of the side sliding grooves 52 and connected to the top of the connecting block 43 at the bottom;

[0050] When the bottom surface support plate 42 moves outward, the connecting block 43 is driven to move the side support plate 53 outward, so that the side support plate 53 blocks and protects the side distance, avoiding the falling of materials or workers from the side distance;

[0051] The outer side walls of the guardrail columns 21 are fixedly connected with distance measuring sensors 60, which are electrically connected with the hydraulic cylinder 45;

[0052] The distance measuring sensor 60 is a non-contact laser distance measuring device, which monitors the distance between the elevator and the guardrail column 21 in real time, feeds back the data to the control system (single-chip microcomputer), and triggers the hydraulic cylinder 45 to act when the distance exceeds the safety threshold (the distance between the floor protection device and the vertical surface of the cage or landing door should be greater than 150 mm).

[0053] In some embodiments, the bottom plate assembly 10 further comprises a slope 14 arranged on one side of the bottom plate 11. The slope 14 facilitates the unloading of materials.

[0054] In some embodiments, the opening direction of the protective door 30 is inward opening. The inward opening protective door 30 can avoid affecting the operation of the elevator.

[0055] In some embodiments, the bottom surface distance adjusting assembly 40 further comprises a limiting sliding groove 46 arranged on the upper surface of the bottom surface sliding seat 41; and a limiting sliding block 47 fixedly connected to the bottom of the bottom surface support plate 42 and slidably connected with the limiting sliding groove 46. The limiting sliding groove 46 and the limiting sliding block 47 can improve the stability of the sliding of the bottom surface support plate 42 on the bottom surface sliding seat 41.

[0056] In some embodiments, the outer side wall of the side surface sliding seat 51 is provided with a reinforcing rib. The reinforcing rib improves the overall strength of the side surface distance adjusting assembly 50.

[0057] In some embodiments, the distance measuring sensor 60 is provided with two, which are symmetrically arranged on the two guardrail columns 21. The double-symmetric arrangement of the distance measuring sensor 60 can redundantly detect the distance data, ensure the reliability of the adjusting action, and realize multiple safety protection.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present specification.

[0059] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection required by the present application.
