Description

Technical Field

[0001] The invention belongs to the field of engineering construction, and particularly relates to an irregular retractable protective canopy and an installation method. Background Art

[0002] As my country's urban renewal accelerates, many underground space renovation and foundation pit projects are located in urban cores and densely populated areas. During day and night construction, construction activities and mechanical operations can generate dust, noise, and light pollution for surrounding residential, commercial, and office buildings.

[0003] Chinese patent CN 116037600 B discloses a unitized intelligent protective canopy that divides the protective canopy into several protective canopy units. Each protective canopy unit can be freely folded and expanded using a simple drive mechanism. While this technology can achieve folding and expansion, the divided protective canopy units are all rectangular and cannot adapt to the irregular shape of the foundation pit.

[0004] Chinese patent CN 116480011 A discloses a protective canopy system suitable for irregular sites and its installation method. The system divides the construction site into several sections based on site conditions, and sets two groups of support columns in each section according to the terrain of the divided sections. By connecting cantilevered steel supports to the inner tops of some of the support columns, the inner tops of multiple support columns in the same group are aligned on the same horizontal line, allowing for the installation of linear slides and ensuring that the two linear slides are relatively parallel, thus meeting the requirements for opening and closing the dust screen. While this patent can solve the technical problem of fully covering canopies in irregular sites, the system transforms the canopy into parallel structural units by installing a large number of steel support columns, beams, and cantilevered supports. This makes the structure more complex, installation more difficult, and construction costs higher.

[0005] Therefore, it is necessary to design a canopy system that is lightweight, easy to install and suitable for irregular sites, breaking the design concept of conventional canopies that shrink in a rectangular shape. Summary of the Invention

[0016] In addition, an embodiment of the present invention further provides a method for installing the irregular intelligent retractable protective canopy as described above, which mainly includes the following steps: S1. Planning and layout of supports: In the early stage of construction, the positions and spacing of double-track supports and single-track supports are designed and laid out according to the contours of the construction site and the span of the canopy. The construction site can be divided into a single or more than two protective canopy unit systems for layout; Arrange multiple double-track supports and multiple single-track supports along a horizontal straight line, that is, keep all supports on one side on a horizontal straight line, form a layout diagram, and lay out multiple double-track supports and single-track supports on both sides of the construction site according to the layout diagram. At each support position, pre-embed at least 4 pre-embedded bolts in advance, and fix the double-track support and single-track support to the top of the site base structure with bolts respectively; S2.

Assemble the drive and traction mechanism: Install the load-bearing shaft, sprocket, traction motor, and chain on the double-track support to form the drive and traction mechanism. Use the connecting rod on the first sliding trailer at the head end of the first slide rail to pass through the gap so that it moves horizontally with the chain. Driven by the traction motor, the movement of the first sliding trailer can push the remaining sliding trailers in sequence. S4. Mount the curtain. The process is as follows: S4.1. Cut the curtain according to the contours of the construction site. Arrange and secure multiple hollow steel tubes on top of the curtain according to the corresponding relationship between the miniature winch and the pulley to form an opening and closing member. Fold it for use. S4.2. Release the rope from the output shaft of the micro winch and pass it through the recesses of the two guide sheaves. Secure the rope after the end reaches the pulley. Install multiple routing guide assemblies on each rope. S4.3. Gradually unfold the opening and closing components from one end, align the hollow steel pipes with the ropes, and slide the cable guide assembly to ensure even distribution. Then, use the steel pipe clamps to assemble the hollow steel pipes and ropes until the opening and closing components are fully unfolded and all the steel pipe clamps are installed. S5. Pre-operation debugging: By configuring the first travel switch, the second travel switch, the intelligent control system and the environmental monitoring system, and completing the installation and verification of the circuit connection and data programming, adjust the curtain tension to ensure that it is flat and has no obvious wrinkles after unfolding, and switch the curtain between the open state and the closed state to verify that the canopy system opens and closes normally.

[0017] Compared with the prior art, the present invention has the following improvements: The wiring guide assembly is suspended under the rope and connected to the opening and closing components. The contraction switching between the open state and the closed state is realized by driving the traction mechanism, which changes the design concept that the conventional canopy system can only be opened and closed along two relatively parallel linear slides. The canopy system can be automatically opened and closed along two relatively parallel or intersecting linear slides, thereby better adapting to the needs of canopy covering irregular venues and greatly improving the scope of application. By using supports to replace the steel structure support system in conventional protective canopies, the track form is changed from conventional H-type track to C-type steel track, making the canopy system structure lighter, the structure installation and maintenance more convenient, greatly reducing the canopy system construction cost and improving the canopy installation efficiency. By using the output end of the micro winch to adjust and ensure the corresponding change in the rope length during the retraction of the curtain during the switching process, and controlling the tightness of the rope, the curtain is prevented from sinking when it is folded or unfolded, the height of the curtain is maintained, and the curtain is prevented from sinking when it is folded or unfolded. The rope drives the curtain to move during the length change process, and the change in rope length during the contraction of the canopy from opening to closing drives the curtain to move left and right, maintaining the original state of the curtain, significantly improving stability and safety, and extending the service life of the device. By interconnecting the environmental monitoring system and the intelligent control system and coordinating the positioning with the first travel switch and the second travel switch, it is ensured that when the dust index is close to exceeding the standard value, the canopy system is started to cover the construction work surface in time, realizing automatic sensing and feedback control, automatic opening and closing of the protective canopy, and real-time response to environmental data such as dust and noise at the construction site. The present invention can accurately control the opening and closing module of the canopy system, realize automatic opening and closing of the protective canopy and timing judgment, and significantly improve intelligence.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 1-10The irregular intelligent retractable protective canopy shown in the figure provides a protective canopy unit structure, which includes a double-rail support 11 and a single-rail support 21. The double-rail support 11 and the single-rail support 21 are respectively installed with a first slide rail 19 and a second slide rail 20, and a curtain 6 matching the contour of the construction site is arranged between the first slide rail 19 and the second slide rail 20. A plurality of evenly distributed hollow steel pipes 4 are arranged on the top of the curtain 6. A plurality of evenly distributed sliding trailers 13 are movably arranged on the first slide rail 19, and a miniature winch 14 is installed on the sliding trailer 13. A plurality of evenly distributed pulleys 22 are movably arranged on the second slide rail 20. The pulleys 22 are distributed one-to-one with the sliding trailer 13, and the miniature winches 14 are installed on the sliding trailer 13. A rope 5 is wound around the output shaft of the winch 14, and the other end of the rope 5 is installed on the pulley 22, so that it has sufficient traction. At the same time, the output end of the micro winch 14 is used to adjust and ensure the corresponding change in the length of the rope 5 during the retraction of the curtain 6, and the tightness of the rope 5 is controlled to prevent the curtain 6 from sinking when it is folded or unfolded, thereby maintaining the height of the curtain 6 and preventing it from sinking when it is folded or unfolded. Multiple ropes 5 are distributed one by one above the hollow steel pipe 4, and the hollow steel pipe 4 and the curtain 6 are suspended below the rope 5 through the wiring guide assembly 3. The wiring guide assembly 3 connects the rope 5 to the hollow steel pipe 4 to prevent the rope 5 from driving the curtain 6 to move during the length change process, thereby maintaining the original state of the curtain 6. A driving traction mechanism 1 for driving the sliding trailer 13 is provided at the bottom of the first slide rail 19, which includes a chain 16 and a traction motor 15. The traction motor 15 is fixed to the outside of one of the double-track supports 11, and the double-track support 11 is rotatably connected to the load-bearing shaft 12. A sprocket 17 coaxially distributed with the load-bearing shaft 12 is provided in the central channel of the double-track support 11. The chain 16 is chain-driven and sleeved on the outside of multiple sprockets 17, and the output shaft of the traction motor 15 is transmission-connected to one of the load-bearing shafts 12. Under the drive of the traction motor 15, the curtain 6 is retracted and switched between the open state and the closed state.

[0033] In the present application, the protective cover unit structure can be set as one or multiple units can be combined.

[0034] In addition, the protective canopy structure provided in this application can be applied to irregular construction sites, as well as regular construction sites.

[0035] Specifically, in the above technical solution, the number of the wiring guide components 3 is set to be multiple, and the multiple wiring guide components 3 are distributed along the axial direction of the hollow steel pipe 4; The cable guide assembly 3 includes a pulley clamp 32 and a steel pipe clamp 33. The pulley clamp 32 is a frame-shaped structure with two rotatably connected guide sheaves 31 stacked one above the other. The rope 5 passes through the recesses of the two guide sheaves 31 and guides the cable. A slide bar 2 is provided at the bottom of the pulley clamp 32. The steel pipe clamp 33 consists of a fastening bolt 34 and two axially symmetrically distributed hoop plates. The slide bar 2 passes through the top of the two hoop plates and is slidably connected to the through-holes. The fastening bolt 34 is detachably mounted at the bottom of the two hoop plates. The two hoop plates are combined through the fastening bolt 34 to form a hoop structure that matches the hollow steel pipe 4. This ensures that the hollow steel pipe 4 is firmly fixed in the steel pipe clamp 33, preventing the curtain 6 from moving left and right due to changes in the length of the rope 5 during the contraction and reciprocation of the canopy between opening and closing.

[0036] Specifically, in the above technical solution, the first slide rail 19 and the second slide rail 20 are both C-shaped steel structures, the C-shaped groove of the first slide rail 19 is opened upward, and the C-shaped groove of the second slide rail 20 is opened toward the side of the first slide rail 19, and the pulley 22 and the sliding trailer 13 are both equipped with rollers that slide with the inner walls of the corresponding C-shaped grooves; The number of the first slide rails 19 is set to two, the two first slide rails 19 are distributed in parallel, and a gap is reserved between the two first slide rails 19 .

[0037] Specifically, in the above technical solution, the first sliding trolley 13 at the tail end of the first slide rail 19 is locked with the first slide rail 19, and a connecting rod 18 is installed at the bottom end of the first sliding trolley 13 at the head end of the first slide rail 19, and the connecting rod 18 passes through the gap and is hung on the chain 16; A first travel switch 9 and a second travel switch 10 are provided on the first slide rail 19, which are respectively used to sense the timing when the curtain 6 is fully extended and fully retracted, and to feedback signals; the installation position of the first travel switch 9 corresponds to the position of the first sliding trailer 13 at the front end of the first slide rail 19 when the curtain 6 is open; the installation position of the second travel switch 10 corresponds to the position of the second sliding trailer 13 at the rear end of the first slide rail 19 when the curtain 6 is closed.

[0038] Specifically, in the above technical solution, multiple hollow steel tubes 4 are distributed in parallel, and the length of the hollow steel tubes 4 is positively correlated with the cross-sectional length of the construction site where they are located. When the curtain 6 is opened, it is stretched out in a tensioned manner and fixedly connected to the outer surface of the hollow steel tubes 4 to prevent the curtain 6 from sinking like a hood. To ensure the strength of the connection and realize the combination of the hollow steel tubes 4 and the hoop structure, interval-type sections of the hollow steel tubes 4 are connected to the curtain 6. The connection locations include the two ends of the hollow steel tubes 4 and the middle position between two adjacent hoop structures. The length of the hollow steel tubes 4 is less than or equal to the width of the curtain 6 at the cross-section at the location where the hollow steel tubes 4 are located.

[0039] Specifically, in the above technical solution, the number of double-rail supports 11 and single-rail supports 21 is set to multiple, multiple double-rail supports 11 are distributed along a straight track parallel to the center line of the first slide rail 19, and multiple single-rail supports 21 are distributed along a straight track parallel to the center line of the second slide rail 20.

[0040] The protective canopy also includes an environmental monitoring system 8 installed at the construction site, which includes a dust particle concentration detector and a noise detector to collect information including the dust particle concentration and noise pollution index at the construction site.

[0041] like Figure 1 and Figure 11 As shown, the output end of the environmental monitoring system 8 is equipped with an intelligent control system 7, which includes a servo control module 71, a data acquisition and analysis module 72, and a canopy system opening and closing module 73. The data acquisition and analysis module 72 and the canopy system opening and closing module 73 are electrically connected to the input and output ends of the servo control module 71, respectively. The servo control module 71, the data acquisition and analysis module 72, and the canopy system opening and closing module 73 cooperate with each other. The data acquisition and analysis module 72 receives feedback signals from the first and second travel switches 9, 10, as well as the collected data from the environmental monitoring system 8. When the collected data approaches a set value (such as a national or local requirement), the traction motor 15 and the micro-winch 14 are programmed to coordinate operation, automatically starting and stopping the canopy opening and closing operation. Specifically, after the data from the environmental monitoring system 8 is processed and analyzed by the data acquisition and analysis module 72 through an algorithm, a control signal is generated and fed back to the servo control module 71. Based on the signal instructions, the servo control module 71 precisely controls the canopy system opening and closing module 73, achieving automatic opening and closing of the protective canopy.

[0042] Specifically, in the above technical solution, the intelligent control system 7 further includes a remote control module 74. After receiving the remote command, the remote control module 74 feeds the command back to the servo control module 71. like Figure 12 As shown, remote control module 74 utilizes one or a combination of two or more of an infrared remote control unit 741, an electromagnetic wave remote control unit 742, a network data signal remote control unit 743, and a mobile phone app remote control unit 744. The aforementioned embodiments of remote control module 74 are all mature technologies, and those skilled in the art will be able to understand their operating principles and implement their functions. Extensive description is omitted here. Through the aforementioned solutions, the system supports real-time monitoring and manual intervention functions, ensuring the coordinated and efficient operation of various system modules.

[0043] In addition, an embodiment of the present invention further provides a method for installing the above irregular intelligent retractable protective canopy, which mainly includes the following steps: S1. Planning, layout, and placement of supports: In the early stages of construction, the positions and spacing of the double-track supports 11 and the single-track supports 21 are laid out based on the contours of the construction site and the span of the canopy. Multiple double-track supports 11 and multiple single-track supports 21 are arranged along a horizontal straight line to form a layout diagram. Multiple double-track supports 11 and single-track supports 21 are laid out on both sides of the construction site according to the layout diagram and are installed on top of the site's base structure, for example, by bolting or direct welding. S2. Install the rails and railcars: Install two sets of first slide rails 19 on the double-rail support 11, install a set of second slide rails 20 on the single-rail support 21, slide multiple sliding trolleys 13 with miniature winches 14 into the C-shaped grooves of the first slide rails 19, lock the first sliding trolley 13 at the rear end of the first slide rail 19 to the first slide rail 19 with bolts, slide multiple pulleys 22 into the C-shaped grooves of the second slide rail 20, adjust the spacing between two adjacent miniature winches 14 and two adjacent pulleys 22 so that they are evenly spaced, and ensure that the miniature winches 14 correspond to the pulleys 22 one-to-one; S3. Assemble the drive traction mechanism 1: Install the load-bearing shaft 12, sprocket 17, traction motor 15, and chain 16 on the double-track support 11 to form the drive traction mechanism 1. Use the connecting rod 18 on the first sliding trolley 13 at the head end of the first slide rail 19 to pass through the gap, so that it moves horizontally with the chain 16. Driven by the traction motor 15, the movement of the first sliding trolley 13 can push the remaining sliding trolleys 13 in sequence. The operation of this structure is similar to the opening and closing method of curtains. S4, mounting curtain 6, the process is as follows: S4.1. Cut the curtain 6 according to the contours of the construction site. Arrange and secure multiple hollow steel tubes 4 on top of the curtain according to the corresponding relationship between the micro winch 14 and the pulley 22 to form an opening and closing member. Fold it for use. S4.2. Release the rope 5 from the output shaft of the micro winch 14 and pass it through the recesses of the two guide sheaves 31. Once the end reaches the pulley 22, secure it. Install multiple routing guide assemblies 3 on each rope 5. S4.3. Gradually unfold the opening and closing member from one end, aligning the hollow steel tube 4 with the rope 5. Slide the routing guide assembly 3 to evenly distribute the wires. Then, use the steel tube clamp 33 to assemble the hollow steel tube 4 and the rope 5. After the opening and closing member is fully unfolded, all the steel tube clamps 33 are installed. S5. Pre-operational debugging: After configuring the first and second travel switches 9, 10, intelligent control system 7, and environmental monitoring system 8, and completing the installation and verification of circuit connections and data programming, adjust the tension of the curtain 6 to ensure that it is flat and wrinkle-free after unfolding. The curtain 6 is retracted and switched between the open and closed states to verify that the canopy system opens and closes normally. After installation, a final comprehensive debugging of the intelligent control system 7 and an overall inspection of the entire system are required to ensure that all equipment is correctly connected and functioning properly. Actual operational drills are conducted, simulating automatic response and manual operation in various weather and emergency situations. Finally, operational training is provided to engineering personnel to ensure they are familiar with the system's daily use, maintenance, and troubleshooting procedures.

[0044] The protective canopy provided by the present invention can be applied to irregular construction sites. When in use, data including dust particle concentration and noise pollution index are collected through the environmental monitoring system 8 arranged at the construction site, and the data are compared with the set value. When the collected value is close to the set index, the open state and closed state of the curtain 6 are switched. For example, when switching from the open state to the closed state, the traction motor 15 is started. Under its drive, the movement of the first sliding trailer 13 can push the remaining sliding trailers 13 to move toward the tail end of the first slide rail 19 in turn until the second sliding trailer 13 at the tail end moves to the end position, that is, when the second travel switch 10 is touched and the feedback signal is fed back, the traction motor 15 is controlled to stop.

[0045] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
