Description

Technical Field

[0001] This invention relates to the field of municipal engineering construction technology, and in particular to a multifunctional mobile canopy for municipal engineering. Background Technology

[0002] With urbanization and the continuous expansion of major cities, roads built in the early urban areas can no longer meet the current traffic flow. In mature areas, it is impractical to build elevated roads to expand existing roads; instead, tunnels are often constructed beneath the existing roads, which has less impact on the residential areas on both sides. Tunnels are generally constructed using the cut-and-cover method, with one half being constructed first, followed by the other half. However, the construction site is located in a bustling urban area with dense residential communities and heavy traffic. It is foreseeable that residents and businesses in the surrounding area will strongly complain about dust, noise, nighttime construction, and potential damage to buildings during the construction period.

[0003] To address the issue of reduced efficiency, a mobile canopy is typically installed above the tunnel excavation site. Inside, facilities such as sprinklers, monitoring systems, and lighting are installed. The installation of the mobile canopy can reduce the impact of noise and dust on the surrounding environment and residents. It also allows for all-weather construction, making construction unaffected by weather and seasonality, thus improving construction efficiency and accelerating the construction progress.

[0004] Different segments of the movable canopy can be retracted and expanded according to the production conditions of the foundation pit. Before construction, a feasibility study is conducted, and a sample section is produced. Then, the sample section of the canopy is installed on-site to verify the design. Following this, large-scale production, debugging, and installation proceed. However, the resulting movable canopy is only suitable for tunnels of the current width. Figure 1 As shown, the spacing of the steel rails (3) on the two sides of the foundation pit support (1) is determined by the width of the tunnel, while the length of the truss beams (5) is customized according to the spacing of the steel rails (3), and the curtain (23) is connected between each truss beam (5). Therefore, the resulting movable canopy is only suitable for tunnels of the current width, and will not be applicable to tunnels with increased or decreased width. This results in problems such as low utilization rate of the movable canopy and extended construction period due to the inclusion of the production time of the movable canopy. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to increase the applicability of mobile canopies and provide a multifunctional mobile canopy for municipal engineering.

[0006] The technical solution of this invention is a multi-functional mobile canopy for municipal engineering, comprising two side plate devices installed between two foundation pit supports. Each of the two side plate devices has a steel rail at its top, and each steel rail has a scissor arm extending along its length. A truss beam is provided between the upper ends of the opposing scissor arms on both sides. The upper ends of the scissor arms are connected to the ends of the truss beams via universal joints. An outer protective plate with a height exceeding that of the scissor arms is provided on the outer side of the steel rails. The side plate device includes several irregularly shaped plates connected in sequence. Each irregularly shaped plate includes a long main plate and end plates at both ends of the main plate. A square notch is provided on the upward-facing side of the end plate, and a square insert is provided on the downward-facing side of the end plate. A rotating shaft is detachably connected within the notch, with the axial direction of the rotating shaft along the length direction of the main plate. A shaft hole is provided on the insert, with the axial direction of the shaft along the length direction of the main plate. The insert of each irregularly shaped plate is inserted into the notch of its adjacent irregularly shaped plate and rotatably connected via the rotating shaft. An upper through hole is provided on the main plate near the end plate. The end plate has a downward through hole near the main board. Both the upward and downward through holes are along the width direction of the main board. The side plate assembly also includes a downward push rod device located at the top of the irregular plate and an upward push rod device located at the bottom of the irregular plate. The downward telescopic rod of the downward push rod device passes downward through each of the downward through holes, and the upward telescopic rod of the upward push rod device passes upward through each of the upward through holes. The upward and downward push rod devices operate synchronously so that the ends of the upward and downward telescopic rods are both stopped between a set of two adjacent irregular plates. The height of the side plate assembly exceeds the foundation pit support. The bottom of one side of the side plate assembly is slidably connected to a ground rail, and the bottom of the side plate assembly is provided with a traction device to move along the ground rail.

[0007] In one implementation, the truss beam is a lightweight truss structure.

[0008] In one implementation, a curtain is connected between each of the truss beams.

[0009] In one embodiment, the curtain is made of noise-reducing and rainproof material.

[0010] In one implementation, the curtain and the truss beam are detachably connected.

[0011] In one embodiment, the lower end of the midpoint of the scissor arm is fixed relative to the steel rail, and the remaining lower ends of the scissor arm are provided with rollers. Each roller is embedded in the steel rail, and each roller at the two outer ends of the scissor arm is connected to a traveling mechanism. The two traveling mechanisms control the two ends of the scissor arm to compress towards the middle.

[0012] In one implementation, the walking mechanism is wirelessly connected to a remote controller.

[0013] In one embodiment, the irregularly shaped plate at the bottom is connected to a base plate, the bottom of the bottom has a mounting opening in the middle, and the bottom of the bottom has end feet on both sides of the mounting opening. The base plate is located at the bottom of the side plate device.

[0014] In one embodiment, the bottom of the end foot is E-shaped and embedded in the ground rail. The traction device is located in the ground rail and connected to the end foot. The traction device is provided with a traction wheel that cooperates with the ground rail.

[0015] In one embodiment, the truss beam includes an arc beam, a crossbeam, and inner struts filled within the arc beam and the crossbeam.

[0016] The beneficial effect of this invention compared to the prior art is that, through the synchronized action of the lower push rod device and the upper push rod device, the ends of both the upper and lower telescopic rods are positioned between a set of two adjacent irregularly shaped plates. The upper telescopic rod locks all irregularly shaped plates below this position, making them plate-like. The lower telescopic rod locks all irregularly shaped plates above this position, also making them plate-like. Between the two irregularly shaped plates where the ends of both the upper and lower telescopic rods are positioned, the two plates are relatively rotatable due to the lack of interlocking action of either the upper or lower telescopic rod. At this time, under the action of the traction device, if one side plate device is brought closer to the other side plate device, the aforementioned rotation occurs. Specifically, due to the mutual approach of the two side plate devices, the upper plate, interlocked by the lower telescopic rod, rotates outward until it rotates outward by 90 degrees. At this time, the entire movable canopy is π-shaped. If one side plate device is moved away from the other side plate device, the aforementioned rotation also occurs. Specifically, due to the mutual movement of the two side plate devices, the upper plate, interlocked by the lower telescopic rod, rotates inward until it rotates inward by 90 degrees. At this point, the mobile canopy takes on a low, n-shaped form. The two aforementioned operating methods respectively increase the usability scenarios for tunnels with fewer lanes and tunnels with more lanes. Therefore, this mobile canopy offers advantages such as wide applicability and high utilization rate. Attached Figure Description

[0022] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In one implementation, such as Figure 2-4 As shown.

[0024] The multi-functional mobile canopy for municipal engineering provided in this embodiment includes two side plate devices 2 installed between two foundation pit supports 1. Each side plate device 2 has a steel rail 3 at its top, and a scissor arm 4 extending along its length is installed within each steel rail 3. A truss beam 5 is installed between the upper ends of the opposing scissor arms 4 on both sides. The upper ends of the scissor arms 4 are connected to the ends of the truss beam 5 via universal joints 6. An outer protective plate 7 with a height exceeding that of the scissor arms 4 is installed on the outside of the steel rail 3. The side plate device 2 includes several irregularly shaped plates 8 connected in sequence. Each irregularly shaped plate 8 includes a long main plate 9 and end plates 10 at both ends of the main plate 9. A square notch 11 is provided on the upward-facing side of the end plate 10, and a square insert 12 is provided on the downward-facing side of the end plate 10. A rotating shaft 13 is detachably connected within the notch 11, with the axis of the rotating shaft 13 along the length of the main plate 9. A shaft hole 14 is provided on the insert 12, with the axis of the shaft hole 14 along the length of the main plate 9. The insert 12 of each irregularly shaped plate 8 is inserted into its corresponding... The adjacent irregular plate 8 is connected to the notch 11 by a rotating shaft 13. The main plate 9 is provided with an upper through hole 15 near the end plate 10, and the end plate 10 is provided with a lower through hole 16 near the main plate 9. Both the upper through hole 15 and the lower through hole 16 are along the width direction of the main plate 9. The side plate device 2 also includes a lower push rod device 17 located at the top irregular plate 8 and an upper push rod device 18 located at the bottom irregular plate 8. The lower telescopic rod 19 of the lower push rod device 17 passes downward along each lower through hole 16, and the upper telescopic rod 20 of the upper push rod device 18 passes upward along each upper through hole 15. The upper push rod device 18 and the lower push rod device 17 operate synchronously so that the ends of the upper telescopic rod 20 and the lower telescopic rod 19 are both stopped between a certain set of two adjacent irregular plates 8. The height of the side plate device 2 exceeds the foundation pit support 1. The bottom of one side plate device 2 is slidably connected to the ground rail 21. The bottom of the side plate device 2 is provided with a traction device 22 that moves along the ground rail 21.

[0025] In this embodiment, the two side plate devices 2 are installed between the two foundation pit supports 1. Figure 2 The foundation pit support 1 is not shown in the figure; it can be referenced. Figure 1 The height of the two side panel devices 2 exceeds the foundation pit support 1. During installation, one side panel device 2 is close to the foundation pit support 1; specifically, the side panel device 2 without the traction device 22 is close to the foundation pit support 1. It should also be noted that, in traditional mobile canopies, the curtain height is roughly the same as the ground height after installation. However, in this embodiment, the curtain height exceeds the ground height after installation, and some irregularly shaped panels 8 protrude from the ground. For tunnels with different numbers of lanes, the following adjustments can be made to accommodate more applicable scenarios.

[0026] Through the synchronized action of the lower push rod device 17 and the upper push rod device 18, the ends of the upper telescopic rod 20 and the lower telescopic rod 19 are both stopped between a set of two adjacent irregularly shaped plates 8. The upper telescopic rod 20 locks all irregularly shaped plates 8 below this position, making them plate-like. The lower telescopic rod 19 locks all irregularly shaped plates 8 above this position, also making them plate-like. As for the two irregularly shaped plates 8 between which the ends of the upper telescopic rod 20 and the lower telescopic rod 19 are both stopped, there is no interlocking action between the upper telescopic rod 20 or the lower telescopic rod 19, allowing the two irregularly shaped plates 8 to rotate relative to each other. At this time, under the action of the traction device 22, if one side panel device 2 is brought closer to the other side panel device 2, the aforementioned rotation action occurs. Specifically, due to the mutual approach of the two side panel devices 2, the upper plate, which is interlocked by the lower telescopic rod 19, rotates outward. At this time, the steel track 3, outer protective plate 7, scissor arm 4, etc., also rotate outward. The upper plate and outer protective plate 7 are covered by the curtain 23. Because the scissor arm 4 is connected to the end of the truss beam 5 through the universal joint 6, the steel track 3, outer protective plate 7, and scissor arm 4 can rotate outward by 90 degrees. At this time, the entire movable canopy is π-shaped. If one side panel device 2 is moved away from the other side panel device 2, the aforementioned rotation action also occurs. Specifically, due to the mutual separation of the two side panel devices 2, the upper plate, which is interlocked with the lower telescopic rod 19, rotates inward. At this time, the steel track 3, outer protective plate 7, and scissor arm 4 also rotate inward. The outer protective plate 7 covers the scissor arm 4, and the upper plate, outer protective plate 7, and curtain 23 together form a protective structure. Because the scissor arm 4 is connected to the end of the truss beam 5 through the universal joint 6, the steel track 3, outer protective plate 7, and scissor arm 4 can rotate inward by 90 degrees. At this time, the movable canopy is in the shape of a low n. The above two operation methods respectively increase the application scenarios of tunnels with fewer lanes and tunnels with more lanes. As for how much more or less, it depends on which two irregular plates 8 the ends of the upper telescopic rod 20 and the lower telescopic rod 19 stop between.

[0027] It should be noted that for tunnels wider than the original, the movable canopy can be adjusted within the excavation pit, while for tunnels narrower than the original, it can be adjusted and lowered into the pit using a crane. This results in the movable canopy having advantages such as wide applicability and high utilization rate.

[0028] In one implementation, such as Figure 2 As shown.

[0029] The multi-functional mobile canopy for municipal engineering provided in this embodiment has a lightweight truss structure for its truss beams 5. A curtain 23 connects each of the truss beams 5.

[0030] In this embodiment, a new type of curtain 23 is used to seal the top, and a lightweight truss beam 5 structure is selected as the segmental frame. A drive system is installed at the bottom of the truss beam 5, and the drive system can be selected according to the longitudinal slope. The use of a lightweight truss structure is beneficial for the movement of the canopy.

[0031] In one implementation, such as Figure 2 As shown.

[0032] The multi-functional mobile canopy for municipal engineering provided in this embodiment has a detachable connection between its curtain 23 and truss beam 5. The curtain 23 is made of noise-reducing and rainproof material.

[0033] In this embodiment, noise-reducing curtain material is selected, and the canopy is combined with the retaining walls on both sides of the foundation pit to minimize the impact on the external environment (normal foundation pit excavation noise is 65-85 dB, and after using noise-reducing curtain 23, the noise can be reduced to 50-70 dB). At the same time, different types of curtain 23 can be replaced according to different seasons and scenarios.

[0034] In one implementation, such as Figure 2 As shown.

[0035] The multi-functional mobile canopy for municipal engineering provided in this embodiment has a scissor arm 4 whose lower end is fixed relative to the steel track 3 at the midpoint of its length. The remaining lower ends of the scissor arm 4 are equipped with rollers 24, each roller 24 being embedded in the steel track 3. Each of the rollers 24 at the two outer ends of the scissor arm 4 is connected to a traveling mechanism 25, which controls the two ends of the scissor arm 4 to compress towards the middle. In addition, the traveling mechanism 25 is wirelessly connected to a remote control.

[0036] In this embodiment, the movable canopy is controlled by a remote control to move along the steel track 3. The two traveling mechanisms 25 have their own wheels and are also connected to rollers 24 at the outer ends of the scissor arms 4. Therefore, as the two traveling mechanisms 25 move along the steel track 3, they can compress the ends of the scissor arms 4 to retract the canopy towards the center, and also extend the ends of the scissor arms 4 to expand the canopy to both ends. Furthermore, a sprinkler system can be installed on the frame structure and linked with a dust monitoring system. The PM2.5 concentration monitored reaches 115 ug / m³. 3 The above automatically activates the sprinkler system when the PM2.5 concentration drops to 75 ug / m³. 3 The sprinkler system automatically stops afterward. A lighting system can also be installed on the frame structure to enable all-weather construction. A monitoring system can also be installed on the frame structure to realize the concept of intelligent, civilized, and intensive construction management. Simultaneously, the use of the canopy and sprinkler system reduces structural evaporation during curing, aligning with green and environmentally friendly construction principles. This also demonstrates the multi-functionality of the mobile canopy in this implementation method.

[0037] In one implementation, such as Figure 2 As shown.

[0038] The multi-functional mobile canopy for municipal engineering provided in this embodiment has a bottom plate 26 connected to the irregularly shaped plate 8 at the bottom. An installation port 27 is provided in the middle of the bottom of the bottom, and end feet 28 are provided at both ends of the bottom of the bottom on both sides of the installation port 27. The bottom plate 26 is located at the bottom of the side plate device 2.

[0039] In this embodiment, a base plate 26 is provided at the bottom of the irregular plate 8, and an installation port 27 is provided in the middle of the bottom for the upper push rod device 18 to be installed.

[0040] In one implementation, such as Figure 2 As shown.

[0041] The multi-functional mobile canopy for municipal engineering provided in this embodiment has an E-shaped bottom end 28, which is embedded in the ground rail 21. The traction device 22 is located in the ground rail 21 and connected to the end 28. The traction device 22 is equipped with a traction wheel 29 that cooperates with the ground rail 21.

[0042] In this embodiment, the E-shaped end feet 28 can be embedded in two parallel ground tracks 21. Driven by the traction device 22, the lower plate above the base plate 26 can be dragged along the ground tracks 21 until the upper plate rotates 90 degrees inward or outward, making the entire canopy reach a stable state.

[0043] In one implementation, such as Figure 2 As shown.

[0044] The multi-functional mobile canopy for municipal engineering provided in this embodiment includes an arc beam 30, a crossbeam 31, and an inner strut 32 filled in the arc beam 30 and the crossbeam 31.

[0045] In this embodiment, by setting up the arc beam 30, the crossbeam 31, and the inner strut 32, the top of the canopy is made to be arc-shaped, and the inner strut 32 filled in the arc beam 30 and the crossbeam 31 can strengthen the structure of the truss beam 5.

[0046] The specific embodiments described above further illustrate the inventive purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, or improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
