Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment structure for high-rise elevator installation, and specifically relates to a temporary stabilization device for a chimney construction elevator. Background Technology

[0002] The construction elevator inside the chimney is a vertical transportation device used for chimney construction, maintenance, and other operations. During the installation of this construction elevator, the attachment rod is a key component that ensures the stability of the elevator guide rail support. The attachment rod connects the support to the inner wall of the chimney, counteracts the lateral forces on the support, and prevents the support from swaying or shifting; at the same time, it transfers the load of the support to the chimney structure, avoiding local overload that could lead to deformation or damage.

[0003] Existing construction standards require that the interval between the upper and lower attachment rods should not exceed 9m. In order to further improve the reliability and safety of elevator operation, the engineers designed this interval to be 6m based on the load-bearing capacity of the chimney construction elevator. However, when the height of the free end of the support assembled from standard sections exceeds 3m, the swaying amplitude of the free end increases exponentially until it reaches the installation height of the next layer of attachment rods, at which point the new layer of attachment rods is installed.

[0004] Because of the above, when the height of the free end of the support exceeds 3m, the free end of the support and the cable tray at the top of the support, which is used to support materials and personnel, will become unstable and sway significantly. This puts a lot of psychological pressure on the construction workers on the cable tray and poses a safety hazard. While shortening the interval between the two layers of attachment rods to within 3m can eliminate the safety hazard caused by the swaying of the top of the support, a 6m interval is sufficient to ensure the safe operation of the chimney elevator after completion. Reducing the interval to 3m results in a serious waste of material and labor costs. Utility Model Content

[0005] This utility model provides a temporary stabilizing device for a chimney construction elevator, which solves the problem in the prior art that when the height of the free end of the elevator support is greater than 3m, the free end of the support and the cable tray at the top of the support, which is used to support materials and personnel, become unstable and sway significantly, causing great psychological pressure on the construction workers on the cable tray and posing a safety hazard.

[0006] To achieve the above objectives, this utility model provides a temporary stabilization device for a chimney construction elevator, comprising:

[0007] The central fixed frame is detachably connected to the standard section at the top of the elevator support;

[0008] The balance link is detachably connected at one end to the central fixed frame and detachably connected at the other end to the inner wall of the chimney.

[0009] There are multiple balance rods, which are symmetrically arranged around the support.

[0010] As described above, the temporary stabilization device for a chimney construction elevator provided by this utility model has at least the following beneficial effects:

[0011] 1. This temporary stabilizing device for the chimney construction elevator is detachably connected to the standard section at the top of the elevator support via a central fixed frame. A balance rod is detachably connected at one end to the central fixed frame and at the other end to the inner wall of the chimney. Multiple balance rods are arranged symmetrically around the support. When erecting the standard section, once the free end of the standard section exceeds 3m, the central fixed frame can be connected to the standard section first, and then the two ends of the balance rods can be connected to the central support and the inner wall of the chimney respectively. This balances the lateral force on the free end of the standard section. The multiple balance rods arranged around the support further enhance the balancing effect, preventing the free end of the standard section from swaying. This solves the problem in existing technologies where, when the height of the free end of the elevator support exceeds 3m, the free end of the support and the cable tray at the top of the support, used to support materials and personnel, become unstable, resulting in significant swaying, causing considerable psychological stress on the construction workers on the cable tray, and posing a safety hazard.

[0012] 2. Once the free end of the standard section is erected to a height of 6m, it can be fixed by the attachment rods. At this point, because the connection between the fixing frame and the standard section, the balance rod and the middle fixing frame, and the balance rod and the inner wall of the chimney are all detachably designed, the construction personnel can disassemble the balance rods for use in the next standard section. This solves the problem of existing technology, which, although it can eliminate the safety hazard caused by the swaying of the top of the support by shortening the interval between the two layers of attachment rods to within 3m, still results in a serious waste of materials and labor costs. A 6m interval is sufficient to fully guarantee the safe operation of the chimney elevator after completion. Attached Figure Description

[0018] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

They are not intended to limit the implementation of this invention. The terminology used in this invention is solely for describing specific embodiments and is not intended to limit the invention. For example, terms such as "upper," "lower," "left," and "right," indicating orientation or positional relationships, are based solely on the orientations or positional relationships shown in the drawings and are used only for ease of description and simplification. They do not indicate or imply that the device / structure referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0021] Please see Figure 1 This utility model provides a temporary stabilizing device for a chimney construction elevator to solve the problem in the prior art where, when the height of the free end of the elevator support exceeds 3m, the free end of the support and the cable tray at the top of the support, which supports materials and personnel, become unstable and experience significant swaying. This causes considerable psychological stress on the construction workers on the cable tray and poses a safety hazard. While further shortening the interval between the two layers of attachment rods to within 3m can eliminate the safety hazard caused by the swaying at the top of the support, a 6m interval is sufficient to ensure the safe operation of the chimney elevator after completion. Reducing the interval to 3m results in a serious waste of materials and labor costs. The device includes:

[0022] like Figure 1 The central fixing frame 2 shown is detachably connected to the standard section 3 at the top of the elevator support; the specific detachable connection method will be described below.

[0023] like Figure 1 The balance link 4 shown is detachably connected at one end to the central fixing frame 2, and detachably connected at the other end to the inner wall of the chimney 1; similarly, the specific method of detachment will be described below.

[0024] like Figure 1As shown, there are multiple balance links 4, which are arranged symmetrically around the support.

[0025] like Figure 1 As shown, the temporary stabilizing device for the construction elevator in the chimney 1 is detachably connected to the standard section 3 at the top of the elevator support via the central fixed frame 2. The balance rod 4 has one end detachably connected to the central fixed frame 2 and the other end detachably connected to the inner wall of the chimney 1. Multiple balance rods 4 are arranged symmetrically around the support. When the standard section 3 is being erected, if the free end of the standard section 3 is greater than 3m, the central fixed frame 2 can be connected to the standard section 3 first, and then the two ends of the balance rod 4 can be connected to the central support and the inner wall of the chimney 1 respectively. This balances the lateral force on the free end of the standard section 3. The multiple balance rods arranged around the support further enhance the balancing effect, preventing the free end of the standard section 3 from swaying. This solves the problem in the prior art where, when the height of the free end of the elevator support exceeds 3m, the free end of the support and the cable tray at the top of the support used to support materials and personnel become unstable, resulting in significant swaying, causing considerable psychological pressure on the construction workers on the cable tray and posing a safety hazard.

[0026] like Figure 1 As shown, when the free end of standard section 3 is erected to a height of 6m, it can be fixed by the attachment rod. At this time, because the fixed frame and standard section 3, the balance rod 4 and the middle fixed frame 2, and the balance rod 4 and the inner wall of chimney 1 are all detachably connected, the construction personnel can disassemble the balance rod 4 for use in the next standard section 3. This solves the problem that the existing technology, by shortening the interval between the two layers of attachment rods to within 3m, can eliminate the safety hazards caused by the swaying of the top of the support, but the interval of 6m can fully guarantee the safe operation of the chimney 1 elevator after completion. Reducing the interval to 3m causes a serious waste of material and labor costs.

[0027] In another implementation, please refer to Figure 1 The central fixing frame 2 is rectangular, with its two opposite short sides extending outward from the standard section 3; the rectangular central fixing frame 2 is easy to insert into the standard section 3 and is easy to manufacture, and construction workers can process it using on-site materials.

[0028] like Figure 1 As shown, there are four balance rods 4, which are detachably connected to one corner of the central fixed frame 2, thereby ensuring the stability of the central fixed frame 2, that is, ensuring the stability of the free end of the standard section 3.

[0029] In another implementation, please refer to Figure 1 and Figure 3The central fixing frame 2 is detachably connected to the standard section 3 via a latch 5. The latch 5 includes an "Ω" shaped clamp 51, a first bolt 52, and a first nut. The two sides of the opening of the "Ω" shaped clamp 51 extend outwards, and the clamping arms are provided with fixing holes. The "Ω" shaped clamp 51 clamps the central fixing frame 2 and the standard section 3 in its opening. The first bolt 52 passes through the fixing hole and is locked by the first nut, thereby fixing the central fixing frame 2 and the standard section 3 together.

[0030] In another implementation, please refer to Figure 2 The balance link 4 is detachably connected to the central fixing frame 2 via a hook 6; the hook 6 is easy to install and remove, and the materials are readily available on site, so it does not need to be specially made.

[0031] In another implementation, please refer to Figure 1 The balance link 4 is detachably connected to the embedded plate on the inner wall of the chimney 1 by a second bolt. The second bolt is a high-strength bolt, which is easy to install and disassemble, highly adjustable, and suitable for frequent disassembly and assembly.

[0032] In other implementations, such as Figure 2 As shown, the balance link 4 includes a digital display force gauge 7 and a remote control electric hoist 8. The digital display force gauge 7 and the remote control electric hoist 8 are connected in sequence. The pulling force of the remote control electric hoist 8 is displayed by the digital display force gauge 7. The construction personnel can visually monitor the pulling force of each remote control electric hoist 8 by looking at the digital display force gauge 7, and then adjust the pulling force of the remote control electric hoists 8 of different balance links 4 to the same value by remote control, thereby ensuring the stability of the middle fixed frame 2, that is, ensuring the stability of the free end of the standard section 3.

[0033] In summary, this utility model features a detachable connection between the central fixed frame 2 and the standard section 3 at the top of the elevator support; a balance rod 4, with one end detachably connected to the central fixed frame 2 and the other end detachably connected to the inner wall of the chimney 1; and multiple balance rods 4 arranged symmetrically around the support. When the standard section 3 is being erected, if the free end of the standard section 3 is greater than 3m, the central fixed frame 2 and the standard section 3 can be connected first, and then the two ends of the balance rod 4 can be connected to the central support and the inner wall of the chimney 1 respectively, thereby balancing the lateral force on the free end of the standard section 3. The multiple balance rods arranged around the support further enhance the balancing effect, preventing the free end of the standard section 3 from swaying. This solves the problem in the prior art where, when the height of the free end of the elevator support exceeds 3m, the free end of the support and the cable tray at the top of the support used to support materials and personnel become unstable, resulting in significant swaying, which puts considerable psychological pressure on the construction workers on the cable tray and poses a safety hazard. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
