Description

Technical Field

[0001] This utility model relates to the field of subway construction technology, and in particular to a canopy device for subway construction. Background Technology

[0002] During subway construction, some subway stations are often located in relatively developed areas. Therefore, the construction of each subway station inevitably has a negative impact on the daily lives of the surrounding residents. To mitigate this impact, existing technologies typically use a canopy to enclose the construction site, thereby reducing the impact on the surrounding environment. The canopy consists of an internal skeleton structure and numerous supporting members mounted on the skeleton. The skeleton structure is composed of a series of interconnected vertical beams, horizontal beams, and longitudinal beams. For both the skeleton and the supporting members, appropriate structures are required to enhance connection strength. In existing technologies, connecting two parallel members with inclined members to improve connection strength is a common choice. However, the shortcomings of existing technologies are twofold: firstly, it results in different models of foundation members—foundation members with connecting plates and those without—which increases the difficulty of transportation and installation; secondly, the connection position between the reinforcing member and the foundation member is fixed. If manufacturing and installation errors accumulate, the end of the reinforcing member may not be perfectly aligned with the connecting plate, making installation impossible.

[0003] Chinese patent CN217975573U discloses a canopy device for subway construction, comprising multiple sets of columns forming side walls. These columns are spaced apart along the length of the base, and adjacent columns are interconnected. The spacing between adjacent columns is adjustable. Each column has a pull-out arc rod at its top, forming the canopy of the device. The width of the canopy is adjustable, and a canopy membrane covers the pull-out arc rods. The adjustable width of the canopy allows for adjustment based on actual usage, and the adjustable spacing between adjacent columns allows for adjustment of the canopy's length. This subway construction canopy device facilitates installation, ensures the canopy's strength, and allows for adjustments based on actual usage.

[0004] However, the above-mentioned subway construction canopy device still has the following problems when in use: (1) The subway construction canopy device cannot adapt to the shield tunneling process in urban subway construction; (2) The stability of the subway construction canopy device will be affected by strong winds or uneven ground. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a canopy device for subway construction. On the one hand, by setting up a liftable skylight and a telescopic mechanism connected thereto, the height and opening degree of the canopy can be flexibly adjusted to adapt to the construction needs of different stages. On the other hand, the roof and facade are constructed with a portal steel frame structure and covered with a protective film, which makes the structure stable and able to withstand harsh weather and geographical environment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides a design for a canopy device for subway construction, including a roof and facades connected to the four sides of the roof. The roof includes multiple skylights that are movably connected to the facades. Lifting mechanisms are provided at both ends of each skylight and between each skylight and the facade. Telescopic mechanisms are provided between each skylight and the corresponding lifting mechanism.

[0008] Furthermore, the lifting mechanism includes a drive motor; the output end of the drive motor is connected to a rotating shaft; two first gears are provided on the rotating shaft; two first racks are slidably installed on the inner side of the facade corresponding to the two first gears; the first racks mesh with the first gears; and the first racks are connected to the telescopic mechanism.

[0009] Furthermore, the telescopic mechanism includes an outer tube connected to the first rack; a telescopic component is slidably sleeved inside the outer tube, and a connecting block penetrating the outer tube is connected to the telescopic component, the connecting block being connected to the sunroof.

[0010] Furthermore, the telescopic assembly includes an inner tube that is slidably connected to the outer tube; a transmission tooth groove is formed on the inner side wall of the outer tube; a second rack is coaxially connected to the front end of the inner tube; and a second gear that meshes with the second rack and the transmission tooth groove is provided.

[0011] Furthermore, the facade includes an east facade, a west facade, a south facade, and a north facade; the west facade, the south facade, and the north facade are all equipped with passageway doors and ventilation windows; the bottom of the east facade and the west facade are equipped with insulation panels.

[0012] Furthermore, the roof and the facade are constructed using a portal steel frame structure, with adjacent beams connected to each other as a whole; both the roof and the facade are covered with a protective film.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By installing multiple liftable skylights and connecting them with telescopic mechanisms, the height and opening degree of the canopy can be flexibly adjusted to adapt to the construction needs at different stages. For example, when performing high-altitude operations, the skylights can be raised to provide a larger working space; in severe weather conditions, the skylights can be closed to protect the construction site.

[0015] 2. The roof and facade are constructed using a portal steel frame structure and covered with a protective film, which can effectively resist wind and rain, keep the interior dry, and help maintain the safety of equipment and materials. The bottom of the east and west facades are equipped with insulation boards, which helps to maintain a stable internal temperature and reduce the impact of changes in external temperature on construction.

[0016] 3. The west, south, and north facades are equipped with passageways and ventilation windows, ensuring good air circulation, which helps improve the working environment for construction workers and also helps to remove harmful gases or dust. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0030] Combination Figure 1-8 As shown, this utility model provides a canopy device for subway construction, including a roof 1 and a facade connected to the four sides of the roof 1. The roof 1 includes a plurality of skylights 11 that are movably connected to the facade. Lifting mechanisms 3 are provided at both ends of the skylights 11 and the facade. Telescopic mechanisms 4 are provided between the skylights 11 and the corresponding lifting mechanisms 3.

[0031] It should be noted that the widths of the multiple skylights 11 are different to accommodate various construction needs. One skylight 11 is formed by movably installing two steel frames and span supports in the middle of the roof 1, while another skylight 11 is formed by movably installing four steel frames and span supports near the south facade 22 of the roof 1. The rest of the roof 1 is fixedly installed. The skylights 11 can be opened or closed independently during use, and can be folded together with the rest of the roof 1 via the lifting mechanism 3 and the telescopic mechanism 4, creating a partially exposed structure to adapt to different construction needs and to adjust lighting and ventilation. The facade is stably installed on the foundation, ensuring the overall structure is stable and adaptable to different weather and ground conditions.

[0032] Furthermore, the lifting mechanism 3 includes a drive motor 31; the output end of the drive motor 31 is connected to a rotating shaft 32; two first gears 33 are provided on the rotating shaft 32; two first racks 34 are slidably installed on the inner side of the facade at positions corresponding to the two first gears 33; the first racks 34 mesh with the first gears 33; the first racks 34 are connected to the telescopic mechanism 4.

[0033] The lifting mechanism 3 also includes a housing 35, which is fixedly installed on the inner side of the facade. A drive motor 31 is installed inside the housing 35 to provide power. The first rack 34 is sandwiched between the first gear 33 and the inner side of the facade. Therefore, the first rack 34 will move up and down during the rotation of the first gear 33. Moreover, due to the meshing of the first gear 33 and the first rack 34, the first rack 34 can be limited.

[0034] Furthermore, the telescopic mechanism 4 includes an outer tube 41 connected to the first rack 34; a telescopic component 43 is slidably sleeved inside the outer tube 41, and a connecting block 42 that penetrates the outer tube 41 is connected to the telescopic component 43, and the connecting block 42 is connected to the skylight 11.

[0035] In this embodiment, the telescopic mechanism 4 is controlled by a servo motor. The bottom end of the outer tube 41 is fixedly connected to the first rack 34. When the first rack 34 moves up or down, the outer tube 41 will move up or down accordingly.

[0036] Furthermore, the telescopic component 43 includes an inner tube 431 that is slidably connected to the outer tube 41; a transmission tooth groove 432 is provided on the inner side wall of the outer tube 41; a second rack 433 is coaxially connected to the front end of the inner tube 431; a second gear 434 is provided between the second rack 433 and the transmission tooth groove 432 for mutual meshing.

[0037] The top end of the connecting block 42 is fixedly connected to the bottom end of the steel frame of the skylight 11, providing stable support for the skylight 11. The bottom end of the connecting block 42 is fixedly connected to the top end of the inner tube 431, allowing it to move back and forth with the inner tube 431. The transmission gear grooves 432 are located on the left and right sides of the outer tube 41. When the servo motor drives the second gear 434 to rotate, since the outer tube 41 is fixed, the second gear 434 will move horizontally along the axial direction of the outer tube 41 while rotating. At the same time, the rotation of the second gear 434 further drives the second rack 433, which meshes with it, to move, thereby causing the inner tube 431 to move horizontally, ultimately allowing the inner tube 431 and the second rack 433 to move outside the outer tube 41.

[0038] Furthermore, the facade includes an east facade 2, a west facade 21, a south facade 22, and a north facade 23; the west facade 21, the south facade 22, and the north facade 23 are all provided with passage doors 24 and ventilation windows; the bottom of the east facade 2 and the west facade 21 are provided with insulation boards.

[0039] Furthermore, the roof 1 and the facade are constructed using a portal steel frame structure, with adjacent beams interconnected as a single unit; both the roof 1 and the facade are covered with a protective film. Each skylight is an independent unit, with its two ends movably connected to the facade.

[0040] Working principle: First, the drive motor 31 controls the rotation of the rotating shaft 32, which in turn drives the first gear 33 to rotate. Under the meshing action of the first gear 33 and the first rack 34, the first rack 34 moves upward, thereby pushing the skylight 11 upward to the designated position. Then, the servo motor controls the rotation of the second gear 434. Since the outer tube 41 is fixed, the second gear 434 moves horizontally along the axial direction of the outer tube 41 while rotating. At the same time, the rotation of the second gear 434 drives the second rack 433, which meshes with it, to move, thereby driving the inner tube 431 to move horizontally. Finally, the inner tube 431 and the second rack 433 can move outside the outer tube 41 until they reach the position required for construction and then stop moving.
