Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a safety hovering platform for air duct installation in a shaft. Background Technique

[0002] In engineering fields such as building construction and mine maintenance, especially in the air duct installation operation in a shaft, traditional hovering platforms have some significant problems and limitations. These problems not only affect the construction efficiency but also pose potential threats to the safety of construction workers. For example, when performing precision operations such as air duct installation, existing hovering platforms are generally hoisted by a single rope. As a result, when the rope hoists the platform, it is not only easy to shake but also difficult to achieve precise height and horizontal positioning. This may lead to inaccurate air duct installation and even require repeated adjustments, reducing the work efficiency.

[0003] After retrieval, such as the existing Chinese patent publication number: CN204661064U shaft hanging basket braking and docking device, including a hanging basket, the hanging basket is suspended under the gantry through a hoist steel wire rope. The hoist steel wire rope passes through a fixed pulley installed on the gantry at the top of the shaft and then is connected to the hanging basket. A transverse rod is installed under the top beam of the gantry, and a controller is suspended on the transverse rod. A counterweight is suspended below the controller; the controller includes a transmission shaft, an eccentric hammer is rotatably connected to one end of the transmission shaft, a conductive rod is rotatably connected to the other end of the transmission shaft, and a conductive block is closely attached above the conductive rod; the controller cooperates with the circuit control system of the hoist.

[0004] The cited patent literature also has the same problem. Hoisting by a single rope makes the platform easy to shake when hoisted by the rope and difficult to achieve precise height and horizontal positioning at the same time. This may lead to inaccurate air duct installation and even require repeated adjustments, reducing the work efficiency. Content of the Utility Model

[0033] This embodiment provides a safety hovering platform for installing air ducts in a shaft as shown in Figures 1 to 4 Figure, which includes a hovering platform member 1, a mobile hoisting assembly 9, and a lifting mechanism 10.

[0034] In this embodiment, the hovering platform member 1 is used for hoisting and construction in the shaft. Air duct members 2 are arranged on both sides of the top of the hovering platform member 1; the hovering platform member 1 serves as the main bearing platform for construction personnel and equipment. It provides a stable working surface, and the air duct members 2 are fixed through the arc-shaped card slots 19 arranged on both sides of its top. Ensure the safety and stability during the construction process and facilitate the air duct installation operation. The air duct members 2 are to be installed in the ventilation ducts in the shaft and are firmly fixed on the platform by cooperating with the arc-shaped card slots 19 on the hovering platform member 1, ensuring that the air ducts will not move or fall off during transportation and improving the installation efficiency.

[0035] In this embodiment, the mobile hoisting assembly 9 is horizontally arranged above the shaft and can provide the power for the horizontal linear movement of the hovering platform member 1; the mobile hoisting assembly 9 provides the hovering platform member 1 with the ability to move horizontally. Combining the linear electric guide rail member 5 and the guide rail slider seat 7 components, the platform can move freely above the shaft. It improves the flexibility of the platform and is suitable for shafts of various sizes and shapes.

[0036] In this embodiment, the lifting mechanism 10 is slidably connected to the mobile hoisting assembly 9 and is longitudinally arranged to longitudinally lift and adjust the position of the hovering platform member 1 through its own multi-stage lifting connection and drive; arc-shaped card slots 19 for clamping and bearing the air duct members 2 are symmetrically arranged on both sides of the top surface of the hovering platform member 1. The arc-shaped card slots 19 are used to fix the air duct members 2. Through a specific shape design, the air ducts can be firmly clamped to prevent them from sliding, ensuring the stability of the air ducts during transportation and installation. The lifting mechanism 10 controls the vertical lifting of the hovering platform member 1, which is composed of a first hydraulic column 13 and a second hydraulic column 14, and realizes multi-stage lifting through hydraulic drive, allowing the platform to be accurately positioned at different heights to meet various installation requirements.

[0037] In this embodiment, the mobile hoisting assembly 9 includes two symmetrically arranged support columns 3, a linear electric guide rail member 5 fixedly installed between the tops of the two support columns 3, and a guide rail slider seat 7 slidably installed on the linear electric guide rail member 5. The guide rail slider seat 7, as the connecting component between the lifting mechanism 10 and the linear electric guide rail member 5, wraps around and slides on the linear electric guide rail member 5, and at the same time bears the lifting mechanism 10, ensuring stability during longitudinal movement and also supporting lateral movement.

[0038] In this embodiment, the guide rail slider seat 7 is in a shape of a rectangle with a hole in the middle and is slidably connected to the outer wall on the circumferential side of the linear electric guide rail member 5.

[0039] In this embodiment, the lifting mechanism 10 includes a first hydraulic cylinder 13 fixed to the bottom surface of the guide rail slider seat 7 and a second hydraulic cylinder 14 fixed to the bottom lifting free end of the first hydraulic cylinder 13. The second hydraulic cylinder 14 is fixedly connected to the hovering platform member 1.

[0040] In this embodiment, at one end of the second hydraulic cylinder 14 away from the hovering platform member 1, an installation sleeve 15 is welded. When the installation sleeve 15 is sleeved on the bottom lifting end of the first hydraulic cylinder 13, the installation sleeve 15 is fixedly connected to the bottom end of the first hydraulic cylinder 13 through a locking bolt 16. The first hydraulic cylinder 13, as a part of the lifting mechanism 10, is responsible for the primary lifting action. It provides thrust through the hydraulic system to push the second hydraulic cylinder 14 up and down, realizing a large range of height adjustment to meet different construction requirements. The second hydraulic cylinder 14, as the fine adjustment part of the lifting mechanism 10, further refines the height adjustment to ensure that the platform can be accurately positioned, providing higher precision and stability, which is suitable for precision operations. The installation sleeve 15 connects the second hydraulic cylinder 14 and the first hydraulic cylinder 13 and is fixed through the locking bolt 16 to ensure a tight connection between the two hydraulic cylinders, enhancing the rigidity and stability of the structure and preventing loosening.

[0041] In this embodiment, extension ear plates 12 are symmetrically welded to the outer walls on both sides of the guide rail slider seat 7, and the two extension ear plates 12 are connected to the hovering platform member 1 through a positioning assembly 11.

[0042] In this embodiment, the positioning assembly 11 includes two positioning vertical rod members 8 symmetrically welded to the inner bottom wall of the hovering platform member 1, and each positioning vertical rod member 8 extends upward through the adjacent extension ear plate 12 to the outside.

[0043] In this embodiment, a limit cap 21 is threadedly connected to the top end of the extension ear plate 12, and the diameter size of the limit cap 21 is larger than the diameter size of the through hole on the top surface of the extension ear plate 12.

[0044] In this embodiment, a support base 4 is welded to the bottom end of each support column 3. A guide rail motor 6 is installed at one end of the linear electric guide rail member 5. The inside of the linear electric guide rail member 5 has a lead screw connected to the output shaft of the guide rail motor 6, and the inside of the guide rail slider seat 7 is penetrated by the lead screw in a threaded manner. The linear electric guide rail member 5 realizes the lateral movement of the guide rail slider seat 7. By connecting the built-in lead screw to the guide rail motor 6, it drives the guide rail slider seat 7 to translate along the guide rail, providing a horizontal displacement and facilitating the adjustment of the position of the hovering platform member 1.

[0045] In this embodiment, an installation connection plate 17 is welded to the bottom end of the second hydraulic column 14. The installation connection plate 17 is connected to the inner bottom wall of the hovering platform member 1 by bolts, and the installation connection plate 17 is located between two positioning vertical rod members 8. A platform door 18 is hinged to the outer wall of one side of the hovering platform member 1. External thread paths 20 for connecting with the limit caps 21 are provided at the top ends of each positioning vertical rod member 8. The positioning vertical rod members 8 assist in positioning and supporting the hovering platform member 1, penetrate through the extending ear plates 12, and cooperate with the limit caps 21 to limit the up and down movement of the platform, increasing the stability of the platform in the vertical direction and preventing accidental falling.

[0046] Working principle:

[0047] For the safety hovering platform for installing air ducts in the shaft, the air duct member 2 is fixed on the hovering platform member 1 through the arc-shaped card slots 19 to ensure that the air duct member 2 is stable and does not move. Open the platform door 18, and the construction workers enter the hovering platform member 1 through the hinged platform door 18. The staff can install the air ducts or perform other necessary construction operations on the platform. Confirm that the installation sleeve 15 between the first hydraulic column 13 and the second hydraulic column 14 has been firmly connected through the locking bolts 16, and the second hydraulic column 14 is connected to the hovering platform member 1 through the installation connection plate 17. By turning on the guide rail motor 6, the lead screw inside the linear electric guide rail member 5 rotates. The guide rail slider seat 7 wraps around and slides on the linear electric guide rail member 5, and translates along the guide rail as the lead screw rotates. Adjust the position of the guide rail slider seat 7 as needed so that it can cover the required operation area.

[0048] The on-site hydraulic station provides power for the first hydraulic column 13 and the second hydraulic column 14 through an external control panel. The first hydraulic column 13 extends or contracts, driving the second hydraulic column 14 and the hovering platform member 1 to perform preliminary height adjustment. Further, fine height adjustment is performed through the second hydraulic column 14 to make the hovering platform member 1 reach the required precise height. The positioning vertical rod members 8 penetrate upward through the extending ear plates 12 and are screwed into the limit caps 21 through the external thread paths 20.

[0049] After the construction is completed, disassemble the entire device or move it to the next working location.
