[0002] Current social engineering projects are generally large-scale, such as industrial parks or large residential complexes. These projects often use a large number of large elevators. The construction process involves safety protection and on-site operating platforms. Conventional practices require horizontal and vertical safety protection for elevator shafts. At the same time, to ensure on-site operations, corresponding scaffolding needs to be erected as operating platforms. The workload involved in safety protection and operating platform erection is substantial. This not only limits the progress of the project but also makes cost control difficult, resulting in poor overall construction quality and relatively high costs.
[0003] Therefore, in order to ensure the construction and safety of elevator shafts, it is necessary to develop an operating platform with a multi-turnable structure that integrates safety protection and operation platform, so as to be suitable for the on-site progress and safety management of industrial and civil buildings, thereby achieving the goal of cost reduction and efficiency improvement.

[0010] In a preferred embodiment of the high-turnover elevator shaft collection operation platform of this utility model, the end of the second support rod is connected to the threaded hole on the contact angle by a fastener.
[0011] In a preferred embodiment of the high-turnover elevator shaft assembly operation platform of this utility model, the fastener includes a fastening bolt, and the end of the first support rod away from the extension rod is connected to the threaded hole on the contact angle through the fastening bolt.
[0012] In a preferred embodiment of the high-turnover elevator shaft centralized operation platform of this utility model, the fastener includes a fastening shaft that can pass through the end of the first support rod; an axial through groove is provided on the contact angle that contacts the first support rod, and a fan-shaped groove is provided on the side wall of the contact angle; the fastening shaft passes through the end of the first support rod and engages with the contact angle; the first support rod passes through the fan-shaped groove and can move along the fan-shaped groove; when the first support rod and the contact angle are in a connected state, the first support rod is located in the fan-shaped groove, and the fan-shaped groove provides the first support rod with a rotation space of 0° to 90°.
[0013] As a preferred embodiment of the high-turnover elevator shaft centralized operation platform of this utility model, the first support rod is provided with at least two sets of connecting holes at one end near the extension rod, and the fastening bolt passes through the end of the second support rod and also passes through one of the connecting holes of the first support rod.

This allows the entire device to be moved simply by removing the fastening bolts connecting the first and second support rods, then loosening the bolts connecting the first and second support rods to the first workbench. This allows the first support rod to rotate towards the second support rod, which in turn moves the extension rod towards the second support rod until the extension rod no longer contacts the elevator shaft platform. At this point, a crane can be used to move the entire device to the next floor elevator shaft platform.
[0018] Compared to existing technologies, the integrated device in this invention is easier to move in elevator shaft passages and can be reused without requiring repeated manual assembly. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1
[0029] Reference Figures 1-2 This is the first embodiment of the present utility model. This embodiment provides a high-turnover elevator shaft collection operation platform, including a first workbench 1, a first support rod 2 connected to the first workbench 1 by fasteners 4, and a second support rod 3 connected to the first workbench 1 by fasteners 4.
[0030] The end of the second support rod 3 away from the first workbench 1 is connected to the end of the first support rod 2 away from the first workbench 1 by fastener 4;
[0031] An extension rod 5 is provided at the end of the first support rod 2 that is away from the first worktable 1;
[0032] When moving the first workbench 1 to the elevator shaft at an adjacent floor level, remove the fastener 4 that connects the first support rod 2 and the second support rod 3, and rotate the first support rod 2 so that the extension rod 5 is no longer in contact with the elevator shaft platform X.
[0033] Example 2
[0034] Reference Figures 1-2 This is the second embodiment of the present invention. Unlike the previous embodiment, the extension rod 5 is integrally formed with the first support rod 2, and the extension rod 5 is parallel to the first workbench 1. The extension rod 5 is used to abut against the elevator shaft platform X.
[0035] Specifically, the first worktable 1 has contact angles 6 connected to both sides, and threaded holes are provided on the contact angles 6.
[0036] Furthermore, the end of the second support rod 3 is connected to the threaded hole on the contact angle 6 via a fastener 4.
[0037] Furthermore, the fastener 4 includes a fastening bolt 41. The end of the first support rod 2 away from the extension rod 5 is connected to the threaded hole on the contact angle 6 through the fastening bolt 41. The end of the first support rod 2 near the extension rod 5 is provided with at least two sets of connecting holes 7. The fastening bolt 41 passes through the end of the second support rod 3 and also passes through one of the connecting holes 7 of the first support rod 2.
[0038] In the prior art, because the first support rod 2 and the second support rod 3 at the bottom of the operating platform are fixed, the operating platform cannot adapt to the width of the elevator shaft passage and it is not convenient for the crane to move the entire operating platform.
[0039] In this application, by connecting one end of the first support rod 2 and the second support rod 3 to the first workbench 1 with fastening bolts 41, and simultaneously connecting the other end of the second support rod 3 to the other end of the first support rod 2 with fasteners 4, when the entire device needs to be moved, it is only necessary to remove the fastening bolts 41 that connect the first support rod 2 and the second support rod 3, and then loosen the fastening bolts 41 that connect the first support rod 2 and the second support rod 3 to the first workbench 1, so that the first support rod 2 can rotate in the direction of the second support rod 3. When the first support rod 2 rotates in the direction of the second support rod 3, it drives the extension rod 5 to move in the direction of the second support rod 3 at the same time, until the extension rod 5 is no longer in contact with the elevator shaft platform X. At this time, the entire device can be moved to the next floor elevator shaft platform X by a crane.
[0040] Compared to existing technologies, the integrated device in this invention is easier to move in elevator shaft passages and can be reused without requiring repeated manual assembly.
[0041] Operation process: First, connect the ends of the first support rod 2 and the second support rod 3 to the side wall of the first workbench 1 with fastening bolts 41. Both sides of the first workbench 1 are connected to the first support rod 2 and the second support rod 3. Then, connect the other end of the second support rod 3 to the end of the first support rod 2 near the extension rod 5 with fastening bolts 41.
[0042] After installation, a crane is used to move the entire device to the elevator shaft passage. The extension rod 5, which is connected to the first support rod 2, overlaps with the elevator shaft platform X to provide support for the entire device.
[0043] When the construction is completed and the entire device needs to be moved to the next floor elevator shaft platform X, firstly, remove the fastening bolts 41 that connect the first support rod 2 and the second support rod 3. Then, loosen the fastening bolts 41 on the first support rod 2 and the second support rod 3 that are connected to the first workbench 1, so that the first support rod 2 can rotate in the direction of the second support rod 3. When the first support rod 2 rotates in the direction of the second support rod 3, it drives the extension rod 5 to move in the direction of the second support rod 3 at the same time, until the extension rod 5 is no longer in contact with the elevator shaft platform X. At this time, the entire device can be moved to the next floor elevator shaft platform X by a crane.
[0044] Example 3
[0045] Reference Figure 3 and Figure 4 Unlike embodiment 2, the fastener 4 includes a fastening shaft 42 that can pass through the end of the first support rod 2; an axial through groove 61 is provided on the contact angle 6 that contacts the first support rod 2, and a fan-shaped groove 62 is provided on the side wall of the contact angle 6. The axial through groove 61 and the fan-shaped groove 62 are connected. The fastening shaft 42 passes through the end of the first support rod 2 and engages with the contact angle 6. The first support rod 2 passes through the fan-shaped groove 62 and can move along the fan-shaped groove 62. When the first support rod 2 and the contact angle 6 are in the connected state, the first support rod 2 is located in the fan-shaped groove 62, and the fan-shaped groove 62 provides the first support rod 2 with a rotation space of 0° to 90°.
[0046] The rest of the structure is the same as in Example 2.
[0047] Unlike Embodiment 2, the end of the first support rod 2 away from the extension rod 5 is connected to the contact angle 6 of the side wall of the first working platform through the fastening shaft 42. Usually, the end of the first support rod 2 connected to the first working platform through the fastening shaft 42 does not need to be separated from the first working platform.
[0048] With this configuration, when the end of the second support rod 3 is no longer connected to the end of the first support rod 2 near the extension rod 5, the first support rod 2 can rotate toward the second support rod 3. When both ends of the second support rod 3 are connected to the first working platform and the end of the first support rod 2 respectively, the first support rod 2, the second support rod 3 and the first working platform form a stable triangular structure. At this time, the first support rod 2 cannot rotate toward the second support rod 3.
[0049] Operation process: First, connect the first support rod 2 to the side wall of the first workbench 1 through the fastening shaft 42. Both sides of the first workbench 1 are connected to the first support rod 2 and the second support rod 3. Then, connect the other end of the second support rod 3 to the end of the first support rod 2 near the extension rod 5 through the fastening bolt 41.
[0050] After installation, a crane is used to move the entire device to the elevator shaft passage. The extension rod 5, which is connected to the first support rod 2, overlaps with the elevator shaft platform X to provide support for the entire device.
[0051] When the construction is completed and the entire device needs to be moved to the next floor elevator shaft platform X, first remove the fastening bolts 41 that connect the first support rod 2 and the second support rod 3. Then rotate the first support rod 2 towards the second support rod 3. When the first support rod 2 rotates towards the second support rod 3, it drives the extension rod 5 to move towards the second support rod 3 at the same time until the extension rod 5 is no longer in contact with the elevator shaft platform X. At this time, the entire device can be moved to the next floor elevator shaft platform X by a crane.
[0052] Example 4
[0053] Reference Figures 1-2 and Figure 5 This is the fourth embodiment of the present invention. Unlike the previous embodiments, this embodiment provides a high-turnover elevator shaft operation protection device, including the aforementioned high-turnover elevator shaft operation platform, and further including a load-bearing rod 8, a second workbench 9 disposed at the end of the load-bearing rod 8, and a ladder 10 disposed between the first workbench 1; the end of the load-bearing rod 8 away from the second workbench 9 is connected to the first workbench 1; the first workbench 1, the load-bearing rod 8, and the second workbench 9 cooperate to form a protective space, which is disposed within the construction space of the elevator shaft.
[0054] Specifically, the second workbench 9 is provided with an opening 91, and a cover plate 92 is movably connected to the end face of the second workbench 9 away from the first workbench 1. The cover plate 92 is adapted to the opening 91; the end of the ladder 10 connected to the second workbench 9 is adjacent to the opening 91.
[0055] Furthermore, the ladder 10 is vertically or inclinedly positioned between the first workbench 1 and the second workbench 9.
[0056] In the existing technology, workers work on the first workbench 1. When it is necessary to work on a position that is higher than their own height, it is usually necessary to build a device that is too tall. Such a setup is labor-intensive and prone to safety accidents.
[0057] In this embodiment, the function of setting the second workbench 9 at the end of the first workbench 1 is to facilitate workers to perform high-altitude operations. After setting the second workbench 9 at the end of the first workbench 1, the whole can form a protective device. The specific reason is that the middle of the elevator shaft is a vertical passage. During the construction process, there is a risk that the construction workers may fall from the elevator shaft platform X at the higher level to the elevator shaft platform X at the lower level. In this embodiment, setting the second workbench 9 at the end of the first workbench 1 can solve the problem of falling from the elevator shaft platform X at the higher level to the elevator shaft platform X at the lower level.
[0058] The rest of the structure is the same as in Example 2.
[0059] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.
