[0041] As shown in the accompanying drawings for purposes of the description hereinafter, Figures 1-6 The utility model provides a technical scheme:

[0042] A working platform of an elevator shaft, comprising a support frame 1, a platform body 2, a stand column 3 and a fence assembly 4; wherein:

[0043] The support frame 1 is installed at the lower side of the platform body 2 and matches the elevator shaft mouth and the elevator ring beam, and is used for fixing the working platform in the elevator shaft and supporting the whole upper structure;

[0044] The platform body 2 is installed at the upper end of the support frame 1 and is used for installing the upper structure and simultaneously plugging the elevator shaft interface when in use to ensure the safety of construction workers;

[0045] The stand column 3 is detachably installed at the four corner positions of the surface of the platform body 2;

[0046] The fence assembly 4 is installed between the four stand columns 3 and is used for protecting workers.

[0047] It should be noted that, in the embodiment, the support frame 1, the platform body 2, the stand column 3 and the fence assembly 4 are arranged to form a working platform that can be adjusted and fixed in the elevator shaft. The working platform is convenient for workers to hoist and fix in the elevator shaft when in use, and the fence assembly 4 protects the workers, facilitating the workers to maintain and construct the elevator shaft on the platform body 2. During specific construction, first, the working platform is hoisted in the elevator shaft. When hoisted to the position of the elevator shaft mouth or the elevator ring beam, the support frame 1 is adjusted so that the support frame 1 and the platform body 2 can be supported in the elevator shaft to fix the position of the platform in the elevator shaft, facilitating the workers to maintain and construct on the platform body 2.

[0048] In a preferred embodiment, as shown in Figure 1 and Figure 2 , the support frame 1 is hingedly mounted on the lower side of the platform body 2, comprising a steel support rod 101, a steel support frame 102 and a limiting bolt 103; wherein:

[0049] The steel support rod 101 is hingedly mounted on the lower side of the platform body 2, and the upper end hinge point is located on the lower side of the platform body 2 away from the elevator shaft opening, and a right-angle clamping piece is welded at the lower end of the steel support rod 101, which is used in cooperation with the lower edge of the elevator shaft opening or the elevator ring beam, and is abutted on the lower edge of the elevator shaft opening or the elevator ring beam in use, so as to fix the position of the working platform in the elevator shaft;

[0050] The steel support frame 102 is hingedly mounted on the lower side of the platform body 2, and is used in cooperation with the steel support rod 101, and is abutted on the steel support rod 101 through the steel support frame 102 in use to fix the platform body 2;

[0051] The limiting bolt 103 is detachably mounted on the steel support rod 101, and is used in cooperation with the steel support frame 102 to fix the free end of the steel support frame 102.

[0052] It should be noted that in the present embodiment, by providing the above-mentioned steel support rod 101, steel support frame 102 and limiting bolt 103, the support frame 1 can be adjusted according to the needs in use to fix the position of the platform body 2 in the elevator shaft. At the same time, it is also convenient to automatically disassemble the lower support frame 1 under the rotating action of the steel support rod 101 when the working platform is hoisted again, so as to facilitate the position transformation of the working platform. Specifically, the above-mentioned steel support rod 101 and steel support frame 102 can be made of angle steel.

[0053] In a preferred embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the fence assembly 4 comprises a connecting frame 401 movably sleeved on the surface of two posts 3, and a first guide rail 402 is installed on the connecting frame 401, two connecting plates 404 are installed on the opposite side of the two connecting frames 401, the surface of the connecting plate 404 is fixedly connected with a second guide rail 412, the surface of one of the second guide rails 412 is provided with a hook 407, the bottom end of the hook 407 is fixedly connected with a tool box 408, the first guide rail 402 is arranged in a curved manner, the second guide rail 412 is arranged in a horizontal manner, and the first guide rail 402 is matched with the second guide rail 412; a positioning frame 403 is installed on the side away from the two adjusting plates 412, the bottom end of the positioning frame 403 is fixedly connected with the platform body 2, and a plurality of insertion holes 413 are formed in the surface of the positioning frame 403; one of the insertion holes 413 is inserted with an insertion rod 410 for limiting the connecting plate 404, one end of the insertion rod 410 close to the connecting plate 404 is fixedly connected with the connecting plate 404; and a sliding rail 405 is fixedly connected on the opposite side of the two connecting frames 401, a sliding block 406 is slidingly connected in the inner cavity of the sliding rail 405, one end of the sliding block 406 close to the connecting plate 404 is fixedly connected with the connecting plate 404; a spring 411 is fixedly connected on the side of the surface of the sliding rail 405 close to the connecting plate 404, one end of the spring 411 close to the connecting plate 404 is fixedly connected with the connecting plate 404; the hook 407 is made of two plastic material hooks, and a hinge is arranged between the surfaces of the two hooks.

[0054] The outer surface of the tool box 408 is also provided with a placing hook 409, the material of the placing hook 409 is stainless steel, the number of the placing hook 409 is six, and the six placing hooks 409 are arranged on the front side and the two sides of the tool box 408.

[0055] It should be noted that in this embodiment, when the staff needs to adjust the height of the tool box 408, the two second guide rails 412 are pulled relative to each other, the two connecting plates 404 will displace with the second guide rails 412, and the insertion rod 410 will also move out of the insertion hole 413 of the positioning frame 403, since the connecting frame 401 and the first guide rail 402 are movably connected with the connecting plate 404, the height of the connecting plate 404 will also be adjusted, then the staff adjusts the height of the fence upward or downward, and when the adjustment is completed, only the second guide rail 412 needs to be loosened, at this time the spring 411 will drive the connecting plate 404 to reset, so that the insertion rod 410 on the surface of the connecting plate 404 is inserted into the corresponding insertion hole 413, to support and limit the overall fence guardrail;

[0056] Meanwhile, it needs to be explained that the surface of the insertion rod 410 is provided with a limiting ring, the limiting ring is in contact with the positioning frame 403, and the insertion depth of the insertion rod 410 can be limited when the staff adjusts the height of the fence and the connecting plate 404 is reset. In this way, not only can the position of the connecting plate 404 be prevented from deviating, but also the two ends of the second guide rail 412 can be aligned with the two first guide rails 402, and the sliding smoothness of the tool box 408 will not be affected.

[0057] In specific use: when the staff moves to each part of the platform body 2 to work and needs to use the tools in the tool box 408, the tool box 408 only needs to be pulled along the track of the first guide rail 402 and the second guide rail. At this time, the hook 407 above the tool box 408 limits the tool box 408, so that the effect of arbitrarily adjusting the position of the tool box 408 can be achieved.

[0058] It needs to be explained that in the embodiment, a hinge is installed on the surface of the hook 407, when the hook 407 is displaced to the bending position of the first guide rail 402, the hinge will be bent according to the track of the front hook, which can better make the hook 407 adhere to the bending position of the first guide rail 402, and it is beneficial for the staff to pull the tool box 408 to any position.

[0059] The construction process of using the working platform of the elevator shaft as described in the utility model is as follows:

[0060] When the worker is maintaining or working on the elevator shaft, he can stand on the platform body 2, place the tools and instruments needed in the tool box 408, and the hooks 409 can also hang the tools to a certain extent. When the worker needs to adjust the height of the tool box 408 to meet his own needs, pull the two second rails relatively, at this time the two connecting plates 404 will displace the second rails, and the plug rods 410 on the surface of the connecting plates 404 will also move out of the insertion holes of the positioning frame 403. When the connecting plate 404 is pulled, the spring 411 will contract, and the slide rail 405 and the sliding block 406 will longitudinally limit the connecting plate 404 and the second rail. The connecting frame 401 and the first rail 402 will also displace the height of the connecting plate 404 and the second rail. Then the worker can adjust the height of the fence up or down. When the adjustment is completed, only the second rail needs to be loosened. At this time, the spring 411 will reset the connecting plate 404, so that the plug rod 410 on the surface of the connecting plate 404 is inserted into the corresponding insertion hole, so as to support and limit the overall fence guardrail. When the worker moves to each part of the platform to work and needs to use the tools in the tool box 408, only the tool box 408 needs to be pulled along the track of the first rail 402 and the second rail. At this time, the hooks 407 above the tool box 408 will limit the tool box 408. When encountering a bending position, the hinges on the surface of the hooks 407 will bend the angle of the hooks 407 to adapt to the bending part of the first rail 402, so as to facilitate the worker to maintain and construct the elevator shaft.

[0061] The above is only a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application.
